In sysctl_ifdata(), query the ifnet pointer using the index only
once, rather than querying it, validating it, and then re-querying
it without validating it. This may avoid a NULL pointer
dereference and resulting kernel page fault if an interface is
being deleted while bsnmp or other tools are querying data on the
interface.
The full fix, to properly refcount the interface for the duration
of the sysctl, is in 8.x, but is considered too high-risk for
7.2, so instead will appear in 7.3 (if all goes well).

- Remove redundant bzero(9)'ing of the softc.
- Don't map the framebuffer twice in case the firmware has already
mapped it as besides wasting resources this isn't possible with
all MMUs. This is a bit tricky as a) just because the firmware
provides a property with a virtual address doesn't mean it's
actually mapped (but typically is when the framebuffer is the
console) and b) the firmware doesn't necessarily map it with
the same byteorder as we do. This makes machfb(4) work on machines

- At least Fire V880 have a small hardware glitch which causes the
reception of IDR_NACKs for CPUs we actually haven't tried to send
an IPI to, even not as part of the initial try. According to tests
this apparently can be safely ignored though, so just return if
checking for the individual IDR_NACKs indicates no outstanding

by the combined usage of smp_ipi_mtx makes no difference to this
phenomenon. [1]
- Provide relevant debugging bits already with the initial panic
in case of problems with the IPI dispatch, which would have
allowed to diagnose the above problem without a specially built
kernel.
- In case of cheetah_ipi_selected() base the delay we wait for
other CPUs which also might want to dispatch IPIs on the total
amount of CPUs instead of just the number of CPUs we let this
CPU send IPIs to because in the worst case all CPUs also want
to IPI us at the same time.
- There's no need to wrap kdb_active in #ifdef KDB as it's always

bus_dma(9) conversion and make txp(4) work on all architectures.
o Header file cleanup.
o bus_dma(9) conversion.
- Removed all consumers of vtophys(9) and converted to use
bus_dma(9).
- Typhoon2 functional specification says the controller supports
64bit DMA addressing. However all Typhoon controllers are known
to lack of DAC support so 64bit DMA support was disabled.
- The hardware can't handle more 16 fragmented Tx DMA segments so
teach txp(4) to collapse these segments to be less than 16.
- Added Rx buffer alignment requirements(4 bytes alignment) and
implemented fixup code to align receive frame. Previously
txp(4) always copied Rx frame to align it on 2 byte boundary
but its copy overhead is much higher than unaligned access on
i386/amd64. Alignment fixup code is now applied only for
strict-alignment architectures. With this change i386 and
amd64 will get instant Rx performance boost. Typhoon2 datasheet
mentions a command that pads arbitrary bytes in Rx buffer but
that command does not work.
- Nuked pointer trick in descriptor ring. This does not work on
sparc64 and replaced it with bcopy. Alternatively txp(4) can
embed a 32 bits index value into the descriptor and compute
real buffer address but it may make code complicated.
- Added endianness support code in various Tx/Rx/command/response
descriptor access. With this change txp(4) should work on all
architectures.
o Added comments for known firmware bugs(Tx checksum offloading,
TSO, VLAN stripping and Rx buffer padding control).
o Prefer faster memory space register access to I/O space access.
Added fall-back mechanism to use alternative I/O space access.
The hardware supports both memory and I/O mapped access. Users
can still force to use old I/O space access by setting
hw.txp.prefer_iomap tunable to 1 in /boot/loader.conf.
o Added experimental suspend/resume methods.
o Nuke error prone Rx buffer handling code and implemented local
buffer management with TAILQ. Be definition the controller can't
pass the last received frame to host if no Rx free buffers are
available to use as head and tail pointer of Rx descriptor ring
can't have the same value. In that case the Rx buffer pointer in
Rx buffer ring still holds a valid buffer and txp_rxbuf_reclaim()
can't fill Rx buffers as the first buffer is still valid. Instead
of relying on the value of Rx buffer ring, introduce local buffer
management code to handle empty buffer situation. This should fix
a long standing bug which completely hangs the controller under
high network load. I could easily trigger the issue by sending 64
bytes UDP frames with netperf. I have no idea how this bugs was
not fixed for a long time.
o Converted ithread interrupt handler to filter based one.
o Rearranged txp_detach routine such that it's now used for general
clean-up routine.
o Show sleep image version on device attach time. This will help
to know what action should be taken depending on sleep image
version. The version information in datasheet was wrong for newer
NV images so I followed Linux which seems to correctly extract
version numbers from response descriptors.
o Firmware image is no longer downloaded in device attach time. Now
it is reloaded whenever if_init is invoked. This is to ensure
correct operation of hardware when something goes wrong.
Previously the controller always run without regard to running
state of firmware. This change will add additional controller
initialization time but it give more robust operation as txp(4)
always start off from a known state. The controller is put into
sleep state until administrator explicitly up the interface.
o As firmware is loaded in if_init handler, it's now possible to
implement real watchdog timeout handler. When watchdog timer is
expired, full-reset the controller and initialize the hardware
again as most other drivers do. While I'm here use our own timer
for watchdog instead of using if_watchdog/if_timer interface.
o Instead of masking specific interrupts with TXP_IMR register,
program TXP_IER register with the interrupts to be raised and
use TXP_IMR to toggle interrupt generation.
o Implemented txp_wait() to wait a specific state of a controller.
o Separate boot related code from txp_download_fw() and name it
txp_boot() to handle boot process.
o Added bus_barrier(9) to host to ARM communication.
o Added endianness to all typhoon command processing. The ARM93C
always expects little-endian format of command/data.
o Removed __STRICT_ALIGNMENT which is not valid on FreeBSD.
__NO_STRICT_ALIGNMENT is provided for that purpose on FreeBSD.
Previously __STRICT_ALIGNMENT was unconditionally defined for
all architectures.
o Rewrote SIOCSIFCAP ioctl handler such that each capability can be
controlled by ifconfig(8). Note, disabling VLAN hardware tagging
has no effect due to the bug of firmware.
o Don't send TXP_CMD_CLEAR_STATISTICS to clear MAC statistics in
txp_tick(). The command is not atomic. Instead, just read the
statistics and reflect saved statistics to the statistics.
dev.txp.%d.stats sysctl node provides detailed MAC statistics.
This also reduces a lot of waste of CPU cycles as processing a
command ring takes a very long time on ARM93C. Note, Rx
multicast and broadcast statistics does not seem to right. It
might be another bug of firmware.
o Implemented link state change handling in txp_tick(). Now sending
packets is allowed only after establishing a valid link. Also
invoke link state change notification whenever its state is
changed so pseudo drivers like lagg(4) that relies on link state
can work with failover or link aggregation without hacks.
if_baudrate is updated to resolved speed so SNMP agents can get
correct bandwidth parameters.
o Overhauled Tx routine such that it now honors number of allowable
DMA segments and checks for 4 free descriptors before trying to
send a frame. A frame may require 4 descriptors(1 frame
descriptor, 1 or more frame descriptors, 1 TSO option descriptor,
one free descriptor to prevent descriptor wrap-around) at least
so it's necessary to check available free descriptors prior to
setting up DMA operation.
o Added a sysctl variable dev.txp.%d.process_limit to control
how many received frames should be served in Rx handler. Valid
ranges are 16 to 128(default 64) in unit of frames.
o Added ALTQ(4) support.
o Added missing IFCAP_VLAN_HWCSUM as txp(4) can offload checksum
calculation as well as VLAN tag insertion/stripping.
o Fixed media header length for VLAN.
o Don't set if_mtu in device attach, it's already set in
ether_ifattach().
o Enabled MWI.
o Fixed module unload panic when bpf listeners are active.
o Rearranged ethernet address programming logic such that it works
on strict-alignment architectures.
o Removed unused member variables in softc.
o Added support for WOL.
o Removed now unused TXP_PCI_LOMEM/TXP_PCI_LOIO.
o Added wakeup command TXP_BOOTCMD_WAKEUP definition.
o Added a new firmware version query command, TXP_CMD_READ_VERSION.
o Removed volatile keyword in softc as bus_dmamap_sync(9) should
take care of this.
o Removed embedded union trick of a structure used to to access
a pointer on LP64 systems.
o Added a few TSO related definitions for struct txp_tcpseg_desc.
However TSO is not used at all due to the limitation of hardware.
o Redefined PKT_MAX_PKTLEN to theoretical maximum size of a frame.
o Switched from bus_space_{read|write}_4 to bus_{read|write}_4.
o Added a new macro TXP_DESC_INC to compute next descriptor index.

- Currently the PMAP code is laid out to let the kernel TSB cover the
whole KVA space using one locked 4MB dTLB entry per GB of physical
memory. On Cheetah-class machines only the dt16 can hold locked
entries though, which would be completely consumed for the kernel
TSB on machines with >= 16GB. Therefore limit the KVA space to use
no more than half of the lockable dTLB slots, given that we need
them also for other things.

Use the spitfire VIS block copy/zero functions also with cheetah-

USIII and beyond CPUs have stricter requirements when it comes
to synchronization needed after stores to internal ASIs in order
to make side-effects visible. This mainly requires the MEMBAR #Sync
after such stores to be replaced with a FLUSH. We use KERNBASE in
the kernel and the newly introduced PROMBASE for the loader as the
addresses to FLUSH as these are guaranteed to not trap. Actually,
the USII synchronization rules also already require a FLUSH in
pretty much all of the cases changed.
We're also hitting an additional USIII synchronization rule which
requires stores to AA_IMMU_SFSR to be immediately followed by a DONE,
FLUSH or RETRY. Doing so triggers a RED state exception though so
leave the MEMBAR #Sync. Linux apparently also has gotten away with
doing the same for quite some time now, apart from the fact that
it's not clear to me why we need to clear the valid bit from the
SFSR in the first place.

Use the PROM provided SUNW,set-trap-table to take over the trap

Without this, f.e. a `ofwdump -ap` triggers a fatal reset error or
worse things on machines based on USIII and beyond.
In theory this should allow to remove touching %tba in cpu_setregs(),
in practice we seem to currently face a chicken and egg problem when
doing so however.
The physical address space of cheetah-class CPUs has been extended
to 43 bits so update TD_PA_BITS accordingly. For the most part this
increase is transparent to the existing code except for when reading
the physical address from ASI_{D,I}TLB_DATA_ACCESS_REG, which we
only do in the loader and which was already adjusted in r190002, or
from the OFW translations node.
While at it, ensure we are only taking valid OFW mapping entries
into account.
- USIII-based machines can consist of CPUs running at different
frequencies (and having different cache sizes) so use the STICK
(System TICK) timer, which was introduced due to this and is
driven by the same frequency across all CPUs, instead of the
TICK timer, whose frequency varies with the CPU clock, to drive
hardclock. We use the STICK timers only when absolutely necessary
though as the STICK timers are driven at frequencies as low as
5MHz, resulting in bad granularity compared to the TICK timers.
However, don't employ the workaround for the BlackBird erratum #1
when using the TICK timer on machines with cheetah-class CPUs for
performance reasons.
Note that using the STICK counter also causes a hang with USIIIi
MP machines for reasons unknown, but these can only consist of
identical CPUs anyway.
- Given that we only (try to) synchronize the (S)TICK timers of APs
with the BSP during startup, we could end up spinning forever in
DELAY(9) if that function is migrated to another CPU while we're
spinning due to clock drift afterwards, so pin to the CPU in order
to avoid migration. Unfortunately, pinning doesn't work at the
point DELAY(9) is required by the low-level console drivers, yet,
so switch to a function pointer, which is updated accordingly, for
implementing DELAY(9). For USIII and beyond, this would also allow
to easily use the STICK counter instead of the TICK one here,
there's no benefit in doing so however.
While at it, use cpu_spinwait(9) for spinning in the delay-
functions. This currently is a NOP though.
- Don't set the TICK timer of the BSP to 0 during startup as there's
no need to do so.
- Implement cpu_est_clockrate().
- Unfortunately, USIIIi-based machines don't provide a timecounter
device besides the STICK and TICK counters (well, in theory the
Tomatillo bridges have a performance counter that can be (ab)used
as timecounter by configuring it to count bus cycles, though unlike
the performance counter of Schizo bridges, the Tomatillo one is
broken and counts Sun knows what in this mode). This means that
we've to use a (S)TICK counter for timecounting, which has the old
problem of not being in sync across CPUs, so provide an additional
timecounter function which binds itself to the BSP but has an
adequate low priority.

The IOCTL-interface is intentionally left (and where needed
actually changed) to be completely little-endian as otherwise
we would have to add conversion code for every possible
configuration page to mpt(4), which didn't seem the right
thing to do, neither did converting only half of the user-

Initialize the vblank structures at load time. Previously we did this

disable vblank interrupts if there are no active consumers. This will
fail after a vt switch until another modeset ioctl is called via dpms

This addresses interrupt storms that were noticed after enabling MSI

should handle it in hardware, while others felt it was the drivers
responsibility.

When a statically linked binary is executed (or at least, one without
an interpreter definition in its program header), set the auxiliary
ELF argument AT_BASE to 0 rather than to the address that we would
have mapped the interpreter at if there had been one.
The ELF ABI specifications appear to be ambiguous as to the desired
behavior in this situation, as they define AT_BASE as the base address
of the interpreter, but do not mention what to do if there is none.
On Solaris, AT_BASE will be set to the base address of the static
binary if there is no interpreter, and on Linux, AT_BASE is set to 0.
We go with the Linux semantics as they are of more immediate utility
and allow the early runtime environment to know that the kernel has
not mapped an interpreter, but because AT_PHDR points at the ELF
header for the running binary, it is still possible to retrieve all
required mapping information when the process starts should it be
required. Either approach would be preferable to our current behavior
of passing a pointer to an unmapped region of user memory as AT_BASE.

A partial solution to some of the 'pull the umass device with a

avoidable panic' than a complete solution to removable devices. We
now close the barn door after the horse has gotten lose and has been
hit by a truck, as it were. The barn no longer catches fire in this
case, but the horse is still dead :-).
The vfs_bio.c fix causes us not to put a failed write back into the
dirty pool if the error returned was ENXIO. In that case, the buffer
is treated like any other clean buffer that's being retured. ENXIO
means the device isn't there anymore and will never be there again in
the future, so retrying is futile.
The vfs_mount.c fix treats 'ENXIO' as success for unmounting a file
system. If the device is gone, retrying later won't help and we'll
never be able to unmount the device.

Modify fdcopy() so that, during fork(2), it won't copy file descriptors
from the parent to the child process if they have an operation vector
of &badfileops. This narrows a set of races involving system calls that
allocate a new file descriptor, potentially block for some extended
period, and then return the file descriptor, when invoked by a threaded
program that concurrently invokes fork(2). Similar approches are used
in both Solaris and Linux, and the wideness of this race was introduced
in FreeBSD when we moved to a more optimistic implementation of
accept(2) in order to simplify locking.
A small race necessarily remains because the fork(2) might occur after
the finit() in accept(2) but before the system call has returned, but
that appears unavoidable using current APIs. However, this race is
vastly narrower.
The fix can be validated using the newfileops_on_fork regression test.

read(2), which meant that records longer than the buffer passed to read(2)
were dropped. Instead take the approach of allowing partial reads to be
continued across multiple system calls more in the style of streaming
character device.
This means retaining a record on the per-pipe queue in a partially read
state, so maintain a current offset into the record. Keep the record on
the queue during a read, so add a new lock, ap_sx, to serialize removal
of records from the queue by either read(2) or ioctl(2) requesting a pipe
flush. Modify the kqueue handler to return bytes left in the current
record rather than simply the size of the current record.
It is now possible to use praudit, which used the standard FILE * buffer
sizes, to track much larger record sizes from /dev/auditpipe, such as
very long command lines to execve(2).

Move the code from ufs_lookup.c used to do dotdot lookup, into

"table all {flush | list}" to act on all tables.

has no practical importance; two "tos" flags are represented

r188144:
Standardize the various prison_foo_ip[46] functions and prison_if to
return zero on success and an error code otherwise. The possible errors
are EADDRNOTAVAIL if an address being checked for doesn't match the
prison, and EAFNOSUPPORT if the prison doesn't have any addresses in
that address family. For most callers of these functions, use the
returned error code instead of e.g. a hard-coded EADDRNOTAVAIL or
EINVAL.
Always include a jailed() check in these functions, where a non-jailed
cred always returns success (and makes no changes). Remove the explicit
jailed() checks that preceded many of the function calls.
r188146:
Don't allow creating a socket with a protocol family that the current
jail doesn't support. This involves a new function prison_check_af,

When attempt is made to suspend a filesystem that is already syspended,
wait until the current suspension is lifted instead of silently returning
success immediately. The consequences of calling vfs_write() resume when
not owning the suspension are not well-defined at best.
Add the vfs_susp_clean() mount method to be called from
vfs_write_resume(). Set it to process_deferred_inactive() for ffs, and
stop calling it manually.
Add the thread flag TDP_IGNSUSP that allows to bypass the suspension
point in the vn_start_write. It is intended for use by VFS in the
situations where the suspender want to do some i/o requiring calls to
vn_start_write(), and this i/o cannot be done later.
Note that addition of the mount method and new struct mount field change
the KBI. This was approved by re and no objections on stable@ were
raised.
Add the ffs structures introspection functions for ddb.
Show the b_dep value for the buffer in the show buffer command.
Add a comand to dump the dirty/clean buffer list for vnode.
When downgrading the read-write mount to read-only, do_unmount() sets
MNT_RDONLY flag before the VFS_MOUNT() is called. In ufs_inactive()
and ufs_itimes_locked(), UFS verifies whether the fs is read-only by
checking MNT_RDONLY, but this may cause loss of the IN_MODIFIED flag
for inode on the fs being remounted rw->ro.
Introduce UFS_RDONLY() struct ufsmount' method that reports the value
of the fs_ronly. The later is set to 1 only after the remount is
finished.
In ffs_valloc(), ffs_vget() may fail because insmntque() refused to
insert new vnode into the mount vnode list. Then, for the SU-enabled
mount, ffs_vfree could create freefile dependency. This dependency can
hang around forever since inode is not marked as IN_MODIFIED and
correspondingly inodeblock may be not marked as dirty.
After ffs_vget() fails, retry with FFSV_FORCEINSMQ, mark the inode as
modified, and vput() it immediately. Take care of the dup alloc.
Softdep code may need to instantiate vnode when processing
dependencies. In particular, it may need this while syncing filesystem
being unmounted. Since during unmount MNTK_NOINSMNTQUE flag is set,
that could sometimes disallow insertion of the vnode into the vnode
mount list, softdep code needs to overwrite the MNTK_NOINSMNTQUE flag.
Create the ffs_vgetf() function that sets the VV_FORCEINSMQ flag for
new vnode and use it consistently from the softdep code instead of
ffs_vget().
Add the retry logic to the softdep_flushfiles() to flush the vnodes
that could be instantiated while flushing softdep dependencies.
Introduce the VV_FORCEINSMQ vnode flag. It instructs the insmnque() function
to ignore the unmounting and forces insertion of the vnode into the mount
vnode list.
Change insmntque() to fail when forced unmount is in progress and
VV_FORCEINSMQ is not specified.
Add an assertion to the insmntque(), requiring the vnode to be
exclusively locked for mp-safe filesystems.
MFC note: because zfs in stable/7 does not follow the insmntque() protocol,
the assertion is commented out.
Use the VV_FORCEINSMQ for the creation of the syncvnode.

- If we fall into the loop with our max_len == 0 (the bug
above) we then call in to copy out the data, setup the length
of the waiting to transmit data to 0 and call the mbuf copy routine
which 0 indicates copy all the data to the mbuf chain.. which it
does. This then leaves a "stuck" message on the stream queue with
its size exactly 0 bytes but all the data there and thus nothing
left in the uio structure. We then reach a stuck forever state
never being able to send data.

Add basic WOL support for 82550/82551/82558 and 82559 based
controllers. ICH based controllers are treated as 82559. 82557,
earlier revision of 82558 and 82559ER have no WOL capability.
o WOL support requires help of a firmware so add check whether
hardware is capable of handling magic frames by reading EEPROM.
o Enable accepting WOL frames only when hardware is about to
suspend or shutdown. Previously fxp(4) used to allow receipt of
magic frame under normal operation mode which could cause
hardware hang if magic frame is received by hardware. Datasheet
clearly states driver should not allow WOL frames under normal
operation mode.
o Disable WOL frame reception in device attach so have fxp(4)
immunize against system hang which can be triggered by magic
packets when the hardware is not in fully initialized state.
o Don't reset all hardware configuration data in fxp_stop()
otherwise important configuration data is lost and this would
reset WOL configuration to default state which in turn cause
hardware hang on receipt of magic frames. To fix the issue,
preserve hardware configuration data by issuing a selective
reset.
o Explicitly disable interrupts after issuing selective reset as
reset may unmask interrupts.
r185538:
Make sure to clear PMDR register by writing back power management

Implement TSO for 82550/82551 controllers.
o Configure controller to use dynamic TBD as TSO requires that
operation mode.
o Add a dummy TBD to tx_cb_u as TSO can access one more TBD in TSO
operation.
o Increase a DMA segment size to 4096 to hold a full IP segment
with link layer header.
o Unlike other TSO capable controllers, 82550/82551 does not
modify the first IP packet in TSO operation so driver should
create an IP packet with proper header. Subsequent IP packets
are generated from the header information in the first IP packet
header. Likewise pseudo checksum also should be computed by
driver for the first packet.
o TSO requires one more TBD to hold total TCP payload. To make
code simple for TSO/non-TSO case, increase the index of the
first available TBD array.
o Remove KASSERT that checks the size of a DMA segment should be
less than or equal to MCLBYTES as it's no longer valid in TSO.
o Tx threshold and number of TBDs field is used to store MSS in
TSO. So don't set the Tx threshold in TSO case.
Implement Rx checksum offload for 82559 or later controllers.
82559 or later controllers added simple checksum calculation logic
in RU. For backward compatibility the computed checksum is appended
at the end of the data posted to Rx buffer. This type of simple
checksum calculation support had been used on several vendors such
as Sun HME/GEM, SysKonnect GENESIS and Marvell Yukon controllers.
Because this type of checksum offload support requires parsing of
received frame and pseudo checksum calculation with software
routine it still consumes more CPU cycles than that of full-fledged
checksum offload controller. But it's still better than software
checksum calculation.
o Introduce a new function, fxp_new_rfabuf which allocates a new
Rx buffer and loads DMA map. Also add a function
fxp_discard_rfabuf that handles reusing Rx buffer/DMA map. With
this change fxp_add_rfabuf just handles appending a new RFA to
existing chain.
o Initialize mbuf length in fxp_new_rfabuf.
o Don't reset rnr and have fxp(4) handle received frames even if
it couldn't allocate new Rx buffer. This will make fxp(4) reload
updated RFA under rnr case. The rnr would still be reset to 0 if
polling is active and fxp(4) processed number of allowed Rx
events.
o Update if_iqdrops if fxp(4) couldn't allocate Rx buffer.
Previously fxp(4) used to try to reuse Rx buffer when new buffer
allocation is failed. But fxp(4) didn't take into account loaded
DMA map such that the same DMA map was loaded again without
unloading the map. There is no reason to unload the loaded map and
reload the same map again, just reusing the map is enough. I
believe the spare DMA map in softc was introduced to implement this
behaviour. Also fxp(4) used to stop Rx processing if once Rx buffer
allocation or DMA map load fails which in turn resulted in losing
incoming frames under heavy network load. With this change fxp(4)
should survive from resource shortage condition.
- Allow fxp_encap() enqueue failed transmissions and set
IFF_DRV_OACTIVE to note resource shortage to upper stack.
- Don't count number of mbuf chains. Default 32 DMA segments for a
frame is enough for most cases. If bus_dmamap_mbuf_sg fails use
m_collapse(9) to collapse the mbuf chain instead of relying on
expensive m_defrag(9).
- Move bpf handling to fxp_start_body() which is supposed to be
more appropriate place.
- Always arm watchdog timer whenever a new Tx request is made.
Previously fxp(4) used to arm watchdog timer only when
FXP_CXINT_THRESH-th Tx request is made. Because fxp(4) does not
rely on Tx interrupt to reclaim transmitted mbufs it's better to
arm watchdog timer to detect potential lockups.
- Add more aggresive Tx buffer reclaiming in fxp_start_body to make
room for new Tx requests. Since fxp(4) does not request Tx
completion interrupt for every frames it's necessary to clean
TXCBs in advance to saturate link.
- Make fxp(4) try to start more packets transmitting regardless of
interrupt type in fxp_intr_body.
Move unarming watchdog timer and pending multicast configuration
check to fxp_txeof(). While I'm here unarm watchdog timer only if
there are no pending queued Tx requests.
Previously the watchdog timer was unarmed whenever Tx interrupt is
raised. This could be resulted in hiding root cause of watchdog
timeouts.
Fix Tx/Rx checksum offload ioctl handling and make Rx handler honor
checksum offload configuration. Now checksum offload can be
controlled by ifconfig(8).
While I'm here add an additional check for interface capabilities
before applying user's request.
Reuse the mbuf that was just retrieved from the receive ring if mbuf
exhaustion is encountered. There was a fix made previously for this
problem but the solution (breaking out of the receive loop) does not
seem to work. mbuf reuse strategy is already adopted by other drivers
such as if_bge. The problem was recreated and the patch is also
verified in the same test environment.
Remove local jumbo locator and switch to UMA backed page allocator
for jumbo frame.
o Nuke unneeded jlist lock which was used to protect jumbo buffer
management in local allocator.
o Added a new tunable hw.mskc.jumbo_disable to disable jumbo
frame support for the driver. The tunable could be set for
systems that do not need to use jumbo frames and it would
save (9K * number of Rx descriptors) bytes kernel memory.
o Jumbo buffer allocation failure is no longer critical error
for the operation of msk(4). If msk(4) encounter the allocation
failure it just disables jumbo frame support and continues to
work without your intervention.
Using local allocator had several drawbacks such as requirement of
large amount of continuous kernel memory and fixed (small) number
of available buffers. The need for large continuous memory resulted
in failure of loading driver with kldload on running systems.
Also small number of buffer used in local allocator showed poor
performance for some applications.

r186214:
It seems that RealTek PCIe controllers require an explicit Tx poll
command whenever Tx completion interrupt is raised. The Tx poll
bit is cleared when all packets waiting to be transferred have been
processed. This means the second Tx poll command can be silently
ignored as the Tx poll bit could be still active while processing
of previous Tx poll command is in progress.
To address the issue re(4) used to invoke the Tx poll command in Tx
completion handler whenever it detects there are pending packets in
TxQ. However that still does not seem to completely eliminate
watchdog timeouts seen on RealTek PCIe controllers. To fix the
issue kick Tx poll command only after Tx completion interrupt is
raised as this would indicate Tx is now idle state such that it can
accept new Tx poll command again. While here apply this workaround
for PCIe based controllers as other controllers does not seem to
have this limitation.

Update jail startup script for multi-IPv4/v6/no-IP jails.
Note: this is only really necessary because of the ifconfig

Consensus among simon and I is that the logic should
really be factored out from the startup script and put
into a proper management solution.
- We now support starting of no-IP jails.
- Implement jail_<jname>_ip options to support both
address familes with regard to ifconfig logic.

address returned usually did not belong to the jail.
Like for v6, if there was an ifr_addr given on v4, you could probe
for more addresses on the interfaces that you were not allowed to see
from inside a jail. Return an error (EADDRNOTAVAIL) in that case
now unless the address is on the given interface and valid for the

This enhances the current jail implementation to permit multiple
addresses per jail. In addtion to IPv4, IPv6 is supported as well.
Due to updated checks it is even possible to have jails without
an IP address at all, which basically gives one a chroot with
restricted process view, no networking,..
SCTP support was updated and supports IPv6 in jails as well.
Cpuset support permits jails to be bound to specific processor
sets after creation.
Jails can have an unrestricted (no duplicate protection, etc.) name
in addition to the hostname. The jail name cannot be changed from
within a jail and is considered to be used for management purposes
or as audit-token in the future.
DDB 'show jails' command was added to aid debugging.
Proper compat support permits 32bit jail binaries to be used on 64bit

Add a new flag to dumpfs(8), -f, which causes dumpfs to list all free
fragments in the file system by fragment (block) number. This new
mode does the necessary arithmetic to generate absolute fragment
numbers rather than than the cg-relative numbers printed in the default
mode.
If -f is passed once, contiguous fragment ranges are collapsed into
an X-Y format as free block lists are currently printed in regular
dumpfs output, but if specified twice, all block numbers are printed
individually, allowing both compact and more script-friendly
representation.
This proves quite handy when attempting to recover deleted data, as it
allows exclusion of non-deleted data from blocks searched.

- Add private tx/rx buffer management to support large frame sizes and update
the rx code to handle multiple frames in a single usb transfer. AX772 parts
(at least) exhibit many input errors when operated with a 2K rx buffer and
no errors w/ a 4K rx buffer (it's unclear what the cause of the errors is
for 2K so this may just be covering up the real issue). Larger rx buffer
sizes show no significant performance improvement for AX772. Bypassing the
common buffer management routines also eliminates an extra context switch on
every packet which noticeably improves performance (TCP netperf rx goes from
45 Mb/s to 85 MB/s).
- Apply le*toh() or htole*() to the variables of which we use the address as
the buffer pointer in the call to axe_cmd(). This is needed to make the code
work on big-endian machines.

Following a fair amount of real world experience with ACLs and
extended attributes since FreeBSD 5, make the following semantic

- Don't update the inode modification time (mtime) when extended
attributes (and hence also ACLs) are added, modified, or removed.
- Don't update the inode access tie (atime) when extended attributes
(and hence also ACLs) are queried.
This means that rsync (and related tools) won't improperly think
that the data in the file has changed when only the ACL has changed.
Note that ffs_reallocblks() has not been changed to not update on an
IO_EXT transaction, but currently EAs don't use the cluster write
routines so this shouldn't be a problem. If EAs grow support for

Likewise, replace the single global condition variable used to signal

variable to avoid spurious wakeups when event subscriptions differ
across multiple pipes.
This slightly increases the cost of delivering to audit pipes, but should

overheading when different pipes are used in different ways.

executed with this vnode.
To keep the size of the struct vm_page and offsets of the fields
accessed by out-of-tree modules, swap the types and locations of the
wire_count and cow fields. Add safety checks to detect cow overflow and
force fallback to the normal copy code for zero-copy sockets.
Change configuration order to enable output only after codec is configured.

Check the return values of contigmalloc(9) as well as bus_dma(9)

they indicate failure. This fixes a panic seen on sparc64 machines
with no free physical memory in the requested 32-bit region but
still doesn't make dcons(4)/dcons_crom(4) these work.
Given that the buffer dcons_crom(4) exposes is used for both input
and output, set BUS_DMA_COHERENT when creating the DMA map used for
loading the buffer. As a side-effect this solves locking issues on
sparc64 when dcons(4) calls bus_dmamap_sync(9) while in an interrupt
filter, which are executed in a critical section, and iommu(4) has
to use a sleep lock when taking advantage of the streaming buffer.

Since we don't request reset for rlphy(4), the link state 'UP'
event from mii(4) may not be delivered if valid link was already
established. To address the issue, check current link state after
driving MII_TICK. This should fix a regression introduced in
r184245.
r184245:
Implement miibus_statchg handler. It detects whether rl(4)
established a valid link or not.
In rl_start_locked, don't try to send packets unless we have valid
link. While I'm here add a check that verifies whether driver can
accept Tx requests by inspecting IFF_DRV_OACTIVE/IFF_DRV_RUNNING
flag.

Various bus_dma(9) fixes.
- The hardware does not support DAC so limit DMA address space to
4GB.
- Removed BUS_DMA_ALLOC_NOW flag.
- Created separated Tx buffer and Rx buffer DMA tags. Previously
it used to single DMA tag and it was not possible to specify
different DMA restrictions.
- Apply 4 bytes alignment limitation of Tx buffer.
- Apply 8 bytes alignment limitation of Rx buffer.
- Tx side bus_dmamap_load_mbuf_sg(9) support.
- Preallocate Tx DMA maps as creating DMA maps take very long time
on architectures that require real DMA maps.
- Adjust guard buffer size to 1522 + 8 as it should include VLAN
and additional reserved bytes in Rx buffer.
- Plug memory leak in device detach. Previously wrong buffer
address was used to free allocated memory.
- Added rl_list_rx_init() to clear Rx buffer and cleared the
buffer.
- Don't destroy DMA maps in rl_txeof() as the DMA map should be
reused. There is no reason to destroy/recreate the DMA maps in
this driver.
- Removed rl_dma_map_rxbuf()/rl_dma_map_txbuf() callbacks.
- The hardware does not support descriptor based DMA on Tx side
and the Tx buffer address should be aligned on 4 bytes boundary
as well as manual padding for short frames. Because of this
hardware limitation rl(4) always used to invoke m_defrag(9) to
get a 4 bytes aligned single buffer. However m_defrag(9) takes
a lot of CPU cycles on slow machines and not all packets need
the help of m_defrag(9). Armed with the information, don't
invoke m_defrag(9) if the following conditions are true.
1. Buffer is not fragmented.
2. Buffer is aligned on 4 bytes boundary.
3. Manual padding is not necessary.
4. Or padding is necessary but upper stack passed a writable
buffer and the space needed for padding is satisfied.
This change combined with preallocated DMA maps greatly
increased Tx performance of driver on sparc64.
- Moved bus_dmamap_sync(9) in rl_start_locked() to rl_encap() and
corrected memory synchronization operation specifier of
bus_dmamap_sync(9).
- Removed bus_dmamap_unload(9) in rl_stop(). There is no need to
reload/unload Rx buffer as rl(4) always have to copy from the
buffer. It just needs proper bus_dmamap_sync(9) calls before
copying the received frame.
With this change rl(4) should work on systems with more than 4GB
memory.

1. Make it more SMP polite. Previous version uses average CPU load that
often leads to load underestimation. It make powerd with default
configuration unusable on systems with more then 2 CPUs. I propose to use
summary load instead of average one. IMO this is the best we can do without
specially tuned scheduler. Also as soon as measuring total load on SMP
systems is more useful then total idle, I have switched to it.
2. Make powerd's operation independent from number and size of frequency
levels. I have added internal frequency counter which translated into real
frequencies only on a last stage and only as good as gone. Some systems may
have only several power levels, while others - many of them, so adaptation
time with previous approach was completely different.
3. As part of previous I have changed adaptive mode to rise frequency on
demand up to 2 times and fall on 1/8 per time internal.
4. For desktop (AC-powered) systems I have added one more mode - "hiadaptive".
It rises frequency twice faster, drops it 4 times slower, prefers twice
lower CPU load and has additional delay before leaving the highest frequency
after the period of maximum load. This mode was specially made to improve
interactivity of the systems where operation capabilities are more
significant then power consumption, but keeping maximum frequency all the
time is not needed.
5. I have reduced default polling interval from 1/2 to 1/4 of second.
It is not so important for algorithm math now, but gives better system
interactivity.
6. Restore original frequency on exit.
7. getopt(3) returns -1, not EOF.

Work-around a compiler optimization bug, that broke libthr. Massive
inlining resulted in constant propagation to the extend that cmpval
was known to the compiler to be URWLOCK_WRITE_OWNER (= 0x80000000U).
Unfortunately, instead of zero-extending the unsigned constant, it
was sign-extended. As such, the cmpxchg instruction was comparing
0x0000000080000000LU to 0xffffffff80000000LU and obviously didn't
perform the exchange.
But, since the value returned by cmpxhg equalled cmpval (when zero-
extended), the _thr_rtld_lock_release() function thought the exchange
did happen and as such returned as if having released the lock. This
was not the case. Subsequent locking requests found rw_state non-zero
and the thread in question entered the kernel and block indefinitely.
The work-around is to zero-extend by casting to uint64_t.

Add ale(4), a driver for Atheros AR8121/AR8113/AR8114 PCIe ethernet
controller. The controller is also known as L1E(AR8121) and
L2E(AR8113/AR8114). Unlike its predecessor Attansic L1,
AR8121/AR8113/AR8114 uses completely different Rx logic such that
it requires separate driver. Datasheet for AR81xx is not available
to open source driver writers but it shares large part of Tx and
PHY logic of L1. I still don't understand some part of register
meaning and some MAC statistics counters but the driver seems to
have no critical issues for performance and stability.
The AR81xx requires copy operation to pass received frames to upper
stack such that ale(4) consumes a lot of CPU cycles than that of
other controller. A couple of silicon bugs also adds more CPU
cycles to address the known hardware bug. However, if you have fast
CPU you can still saturate the link.
Currently ale(4) supports the following hardware features.
- MSI.
- TCP Segmentation offload.
- Hardware VLAN tag insertion/stripping with checksum offload.
- Tx TCP/UDP checksum offload and Rx IP/TCP/UDP checksum offload.
- Tx/Rx interrupt moderation.
- Hardware statistics counters.
- Jumbo frame.
- WOL.
AR81xx PCIe ethernet controllers are mainly found on ASUS EeePC or
P5Q series of ASUS motherboards. Special thanks to Jeremy Chadwick
who sent the hardware to me. Without his donation writing a driver
for AR81xx would never have been possible. Big thanks to all people

The BCE chips appear to have an undocumented requirement that RX frames
be aligned on an 8 byte boundary. Prior to rev 1.36 (now r176448) this
wasn't a problem because mbuf clusters tend be naturally aligned. The
switch to using split buffers with the first buffer being the embedded
data area of the mbuf has broken this assumption, at least on i386,
causing a complete failure of RX functionality. Fix this for now by
using a full cluster for the first RX buffer. A more sophisticated
approach could be done with the old buffer scheme to realign the m_data
pointer with m_adj(), but I'm also not clear on performance benefits of
this old scheme or the performance implications of adding an m_adj()
call to every allocation.

not using the process's limit, if any. However, if tcp_input() is
called in other contexts that do have limits, this may prevent the
incorrect limit from being used.
Rewrite sbreserve_locked()'s comment on NULL thread pointers, eliminating
an XXXRW about the comment being stale.

Further minor cleanups to UNIX domain sockets:
- Staticize and locally prototype functions uipc_ctloutput(),
unp_dispose(), unp_init(), and unp_externalize(), none of which have
been required outside of uipc_usrreq.c since uipc_proto.c was removed.
- Remove stale prototype for uipc_usrreq(), which has not existed in the
code since 1997
- Forward declare and staticize uipc_usrreqs structure in uipc_usrreq.c
and not un.h.
- Comment on why uipc_connect2() is still non-static -- it is used
directly by fifofs.
- Remove stale comments, tidy up whitespace.
Use soconnect2() rather than directly invoking uipc_connect2() to
interconnect two UNIX domain sockets.
Now that portalfs doesn't directly invoke uipc_connect2(), make it a
static symbol.
Remove stale comment (and XXX saying so) about why we zero the file
descriptor pointer in unp_freerights: we can no longer recurse into
unp_gc due to unp_gc being invoked in a deferred way, but it's still
a good idea.
Remove stale comment: while uipc_connect2() was, until recently, not
static so it could be used by fifofs (actually portalfs), it is now

- Since soreceive_dgram() has a simpler structure, replace several gotos
with a while loop making the invariants more clear.
- In the blocking while loop, don't try to handle cases incompatible with
the loop invariant (since m is always NULL, don't check for and handle
non-NULL).
- Don't drop and re-acquire the socket buffer lock unnecessarily after
sbwait() returns, which may help reduce lock contention (etc).

When an inpcb doesn't have a socket but the inpcb is passed to ipfw
in the transmit path, such as TCPS_TIMEWAIT, fail the credential
extraction immediately rather than acquiring locks and looking up
the inpcb on the global lists in order to reach the conclusion that
the credential extraction has failed.
This is more efficient, but more importantly, it avoids lock

When dropping a packet and issuing a reset during TCP segment handling,
unconditionally drop the tcbinfo lock (after all, we assert it lines
before), but call tcp_dropwithreset() under both inpcb and inpcbinfo
locks only if we pass in an tcpcb. Otherwise, if the pointer is NULL,
firewall code may later recurse the global tcbinfo lock trying to look
up an inpcb.
This is an instance where a layering violation leads not only
potentially to code reentrace and recursion, but also to lock
recursion, and was revealed by the conversion to rwlocks because
acquiring a read lock on an rwlock already held with a write lock is
forbidden. When these locks were mutexes, they simply recursed.

Essentially, neither madvise(..., MADV_DONTNEED) nor madvise(..., MADV_FREE)
work. (Moreover, I don't believe that they have ever worked as intended.)
The explanation is fairly simple. Both MADV_DONTNEED and MADV_FREE perform
vm_page_dontneed() on each page within the range given to madvise(). This
function moves the page to the inactive queue. Specifically, if the page is
clean, it is moved to the head of the inactive queue where it is first in
line for processing by the page daemon. On the other hand, if it is dirty,
it is placed at the tail. Let's further examine the case in which the page
is clean. Recall that the page is at the head of the line for processing by
the page daemon. The expectation of vm_page_dontneed()'s author was that
the page would be transferred from the inactive queue to the cache queue by
the page daemon. (Once the page is in the cache queue, it is, in effect,
free, that is, it can be reallocated to a new vm object by vm_page_alloc()
if it isn't reactivated quickly enough by a user of the old vm object.) The
trouble is that nowhere in the execution of either MADV_DONTNEED or
MADV_FREE is either the machine-independent reference flag (PG_REFERENCED)
or the reference bit in any page table entry (PTE) mapping the page cleared.
Consequently, the immediate reaction of the page daemon is to reactivate the
page because it is referenced. In effect, the madvise() was for naught.
The case in which the page was dirty is not too different. Instead of being
laundered, the page is reactivated.
Note: The essential difference between MADV_DONTNEED and MADV_FREE is
that MADV_FREE clears a page's dirty field. So, MADV_FREE is always
executing the clean case above.
This revision changes vm_page_dontneed() to clear both the machine-
independent reference flag (PG_REFERENCED) and the reference bit in all PTEs
mapping the page.

the destination address for a connect()'d raw socket at the rip6_send()
layer, and then re-acquire the inpcb lock in the rip6_output() layer to
query other options on the socket. Previously, the global raw IP socket
lock was used, which while correct and marginally more consistent, could
add significantly to global raw IP socket lock contention.

Marginally decomplicate set/getsockopt code in ip6_output.c by simply

Rather than checking for a NULL so_pcb in raw_attach(), assert that

Remove unused support for local and foreign addresses in generic raw
socket support. These utility routines are used only for routing and
pfkey sockets, neither of which have a notion of address, so were
required to mock up fake socket addresses to avoid connection
requirements for applications that did not specify their own fake
addresses (most of them).
Quite a bit of the removed code is #ifdef notdef, since raw sockets
don't support bind() or connect() in practice. Removing this
simplifies the raw socket implementation, and removes two (commented
out) uses of dtom(9).
Fake addresses passed to sendto(2) by applications are ignored for
compatibility reasons, but this is now done in a more consistent way
(and with a comment). Possibly, EINVAL could be returned here in
the future if it is determined that no applications depend on the
semantic inconsistency of specifying a destination address for a
protocol without address support, but this will require some amount
of careful surveying.
NB: This does not affect netinet, netinet6, or other wire protocol
raw sockets, which provide their own independent infrastructure with
control block address support specific to the protocol.

Revert the r167541: "Remove unneeded getinoquota() call in the

purpose of instantiating inode dquot from the vn_open(). Since quotas

of the call prevented opened inodes from participation in the quota

o Sort includes and add <endian.h> to support endianness.
o Removed unneeded header files.

- set 4096 alignment limit for Tx/Rx descriptor rings.
- separate Rx buffer tag from Tx buffer tag such that Tx tag
allows up-to 16 segments while Rx buffer tag only allows
single segment.
- it seems the controller has no alignment restrictions on Tx/Rx
buffers. Remove ETHER_ALIGN alignment restriction in Tx/Rx
buffers.
- created a spare Rx dma map which would be used to cope with
failure of loading a dma map.
- make sure to load full Tx/Rx descriptor size for Tx/Rx
descriptor dma maps, previously bfe(4) used to load single
descriptor size for each descriptor rings. I have no idea how
it could be run without problems.
- don't blindly cast bus_addr_t type to 32bits in bfe_dma_map().
- created bfe_dma_free() to free allocated dma memory/tags.
- make sure to invoke bus_dmamap_sync(9) before/after processing
descriptor rings/buffers. Because the hardware has severe dma
address space limitation, bounce-buffers would be always used
on systems with more than 1GB memory during
descriptors/buffers access.
- added Tx descriptor ring initialization function,
bfe_list_tx_init().
- moved producer/consumer index initialization to
bfe_list_tx_init() and bfe_list_rx_init() from
bfe_chip_reset().
- added bfe_discard_buf() which will update loaded descriptors
without unloading/reloading the dma map to speed up error
recovery.
- implemented Tx side bus_dmamap_load_mbuf_sg(9). The number of
segments allowed was chosen to be 16 which should be enough for
non-TSO capable hardwares. Setting SOF bit of Tx descriptor is
done in the last to avoid potential race.
- don't give up sending frames in bfe_start() until the hardware
lacks free descriptors.
- added XXX comment to second kick command and possible workaround.
- implemented Rx side bus_dmamap_load_mbuf_sg(9).
- removed bfe_dma_map_desc() as it's not needed anymore after

With SECURE_NODOTDOT, this isn't needed because we refuse to restore

is a common and perfectly valid idiom that incidentally copies "."
to "..".
Before this, the often-recommended incantation
find -d . | cpio -p <target>
fails to properly carry through dir metadata because each
file copy implicitly creates the parent dir, which cpio subsequently
refuses to overwrite. With this patch, the incantation works
with or without the -d option to find because without it, there
is no implicit dir creation, and with it, the subsequent dir
restore will update the metadata on the dir.

Don't enable TSO by default. Users of RTL8169/8110 reported

silicon bug of controller. Personally I couldn't reproduce it on

For newer PCIe based controllers I have no TSO complaints but
turning off TSO would be more safe. Users who are sure that
their controller works with TSO can still reenable the TSO with
ifconfig(8).
The number of bits reserved for MSS in RealTek controllers is

Detect if the application has cleared the environ variable by setting
the first value (environ[0]) to NULL. This is in addition to the
current detection of environ being replaced, which includes being set to
NULL. Without this fix, the environment is not truly wiped, but appears
to be by getenv() until an *env() call is made to alter the enviroment.
This change is necessary to support those applications that use this
method for clearing environ such as Dovecot and Postfix. Applications
such as Sendmail and the base system's env replace environ (already
detected). While neither of these methods are defined by SUSv3, it is
best to support them due to historic reasons and in lieu of a clean,
defined method.
Add extra units tests for clearing environ using four different methods:
1. Set environ to NULL pointer.
2. Set environ[0] to NULL pointer.
3. Set environ to calloc()'d NULL-terminated array.
4. Set environ to static NULL-terminated array.

resizing, is still required.
In a future change, the ifnet lock should be converted from a mutex to an

Add an XXX comment regarding a bug I introduced when modifying the behavior
of audit log vnode rotation: on shutdown, we may not properly drain all
pending records, which could lead to lost records during system shutdown.
When allocating temporary storage to hold a TCP/IP packet header

with mtod(9) and dtom(9). This eliminates the last use of
dtom(9) in TCP.

The default implementation is augmented for the nfs and smbfs.
In the nfs_advlock, push the Giant inside the nfs_dolock.
Before the change, the vop_advlock and vop_advlockasync have taken the
unlocked vnode and dereferenced the fs-private inode data, racing with
with the vnode reclamation due to forced unmount. Now, the vop_getattr
under the shared vnode lock is used to obtain the inode size, and
later, in the lf_advlockasync, after locking the vnode interlock, the
VI_DOOMED flag is checked to prevent an operation on the doomed vnode.

Workaround design botch in usb: blindly mixing bus_dma with PIO does not
work on architectures with a write-back cache as the PIO writes end up
in the cache which the sync(BUS_DMASYNC_POSTREAD) in usb_transfer_complete

writes out of the cache before usb_transfer_complete is called.
Correct cache handling for xfer requests marked URQ_REQUEST: many (if not
all uses) involve a read but usbd_start_transfer only does a PREWRITE; change
this to BUS_DMASYNC_PREREAD | BUS_DMASYNC_PREWRITE as I'm not sure if any
users do write+read.
Correct the logic : we can just invalidate the cache lines, and not
write-back them, only if PREWRITE is not set, and if the buffer is

interrupt-driven configuration handlers to complete, print out a
diagnostic message every 60 second indicating which handlers are
still running. Do this at most 5 times per run so as to avoid
scrolling out any useful information from the kernel message
buffer.
The interval of 60 seconds was selected based on a best guess as
to the nature of "long enough" and may want to be tuned higher

The kqueue_register() function assumes that it is called from the top of
the syscall code and acquires various event subsystem locks as needed.
The handling of the NOTE_TRACK for EVFILT_PROC is currently done by
calling the kqueue_register() from filt_proc() filter, causing recursive
entrance of the kqueue code. This results in the LORs and recursive
acquisition of the locks.
Implement the variant of the knote() function designed to only handle
the fork() event. It mostly copies the knote() body, but also handles
the NOTE_TRACK, removing the handling from the filt_proc(), where it
causes problems described above. The function is called from the fork1()
instead of knote().
When encountering NOTE_TRACK knote, it marks the knote as influx
and drops the knlist and kqueue lock. In this context call to
kqueue_register is safe from the problems.
An error from the kqueue_register() is reported to the observer as
NOTE_TRACKERR fflag.

Add age(4), a driver for Attansic/Atheros L1 gigabit ethernet
controller. L1 has several threshold/timer registers and they
seem to require careful tuned parameters to get best
performance. Datasheet for L1 is not available to open source
driver writers so age(4) focus on stability and correctness of
basic Tx/Rx operation. ATM the performance of age(4) is far from
optimal which in turn means there are mis-programmed registers or
incorrectly configured registers.
Currently age(4) supports all known hardware assistance including
- MSI support.
- TCP Segmentation Offload.
- Hardware VLAN tag insertion/stripping.
- TCP/UDP checksum offload.
- Interrupt moderation.
- Hardware statistics counter support.
- Jumbo frame support.
- WOL support.
L1 gigabit ethernet controller is mainly found on ASUS
motherboards. Note, it seems that there are other variants of
hardware as known as L2(Fast ethernet) and newer gigabit ethernet
(AR81xx) from Atheros. These are not supported by age(4) and
requires a seperate driver. Big thanks to all people who reported
feedback or tested patches.

Since fdescfs might recurse on itself, adding proper locking to it needed some
tricky workarounds in some parts to make it work. For instance, a descriptor in
fdescfs could refer to an open descriptor to itself, thus forcing the thread to
recurse on vnode locks. Because of this, other race conditions also had to be

Summary:
In some situations we were not clearing pending link state attentions.
Because of this we were not getting further interrupts for link state
changes, thus never went into iface UP state and thus could not transmit.
The only way out of this was an incoming packet generating an rx interrupt
and making us call into bge_link_upd.
What we do now is force an interrupt at the end of bge_ifmedia_upd_locked
so we will call bge_link_upd, clear the link state attention and get
further interrupts.
While the initial version was not expected to work with all chips
the later update in rev. 1.210 is.

When writing trailers in sendfile(2), don't call kern_writev()

Note that the current fix isn't perfect, but better than
panicking: normally we guarantee that simultaneous invocations
of a system call to write on a stream socket won't be
interlaced, which is ensured by use of the socket buffer sleep

Although BSD has historically guaranteed that st_size is the size

The fix is to not stat the directory at all, set the initial

-- lower latency: if packet flow does not exceed pipe bandwidth, packets

-- lower overhead: if packet avoids dummynet scheduler it shouldn't reenter
ip stack later. Such packets can be fastforwarded.

Don't touch MSI enable bit in RL_CFG2 register. For unknown reason
clearing MSI enable bit for MSI capable hardwares resulted in Tx
problems. MSI enable bit is set only when MSI is requested from
user.
In revision 1.70, 1.71 and 1.84 re(4) tried to workaround checksum
offload bugs by manual padding for short IP/UDP frames. Unfortunately
it seems that these workaround does not work reliably on newer PCIe
variants of RealTek chips.
To workaround the hardware bug, always pad short frames if Tx IP
checksum offload is requested. It seems that the hardware has a
bug in IP checksum offload handling. NetBSD manually pads short
frames only when the length of IP frame is less than 28 bytes but I
chose 60 bytes to safety. Also unconditionally set IP checksum
offload bit in Tx descriptor if any TCP or UDP checksum offload is
requested. This is the same way as Linux does but it's not
mentioned in data sheet.
For MSI capable hardwares, enable MSI enable bit in RL_CFG2
register. If MSI was disabled by hw.re.msi_disable tunable
expliclty clear the MSI enable bit.
VLAN hardware tag information should be set for all desciptors of a
multi-descriptor transmission attempt. Datasheet said nothing about
this requirements. This should fix a long-standing VLAN hardware
tagging issues with re(4).
Always honor configured VLAN/checksum offload capabilities.
Previously re(4) used to blindly enable VLAN hardware tag stripping
and Rx checksum offload regardless of enabled optional features of
interface.
Don't map memory/IO resource in device probe and just use PCI
vendor/revision/sub device id of the hardware to probe it.
This is the same way as NetBSD does and it enhances readabilty
a lot.
Overhaul re(4).
o Increased number of Rx/Tx descriptors to 256 for 8169 GigEs
because it's hard to push the hardware to the limit with default
64 descriptors.
TSO requires large number of Tx descriptors to pass a full sized
TCP segment(65535 bytes IP packet) to hardware. Previously it
consumed 32 Tx descriptors, assuming MCLBYTES DMA segment size,
to send the TCP segment which means re(4) couldn't queue more
than two full sized IP packets.
For 8139C+ it still uses 64 Rx/Tx descriptors due to its hardware
limitations. With this changes there are (very) small waste of
memory for 8139C+ users but I don't think it would affect 8139C+
users for most cases.
o Various bus_dma(9) fixes.
- The hardware supports DAC so allow 64bit DMA operations.
- Removed BUS_DMA_ALLOC_NOW flag.
- Increased DMA segment size to 4096 from MCLBYTES because TSO
consumes too many descriptors with MCLBYTES DMA segment size.
- Tx/Rx side bus_dmamap_load_mbuf_sg(9) support. With these
changes the code is more readable than previous one and got a
(slightly) better performance as it doesn't need to pass/
decode arguments to/from callback function.
- Removed unnecessary callback function re_dmamap_desc() and
nuked rl_dmaload_arg structure which was used in the callback.
- Additional protection for DMA map load failure. In case of
failure reuse current map instead of returning a bogus DMA
map.
- Deferred DMA map unloading/sync operation for maximum
performance until we really need to load new DMA map. If we
happen to reuse current map(e.g. input error) there is no need
to sync/unload/load again.
- The number of allowable Tx DMA segments for a mbuf chains are
now 32 instead of magic nseg value. If the number of available
Tx descriptors are short enough to send highly fragmented mbuf
chains an optimized re_defrag() is called to collapse mbuf
chains which is supposed to be much faster than m_defrag(9).
re_defrag() was borrowed from ath(4).
- Separated Rx/Tx DMA tag from a common DMA tag such that Rx DMA
tag correctly uses DMA maps that were created with DMA alignment
restriction(8bytes alignments). Tx DMA tag does not have such
alignment limitation.
- Added additional sanity checks for DMA ring map load failure.
- Added additional spare Rx DMA map for graceful handling of Rx
DMA map load failure.
- Fixed misused bus_dmamap_sync(9) and added missing
bus_dmamap_sync(9) in re_encap()/re_txeof()/re_rxeof().
o Enabled TSO again as re(4) have reasonable number of Tx
descriptors.
o Don't touch DMA address of a Tx descriptor in re_txeof(). It's
not needed.
o Fix incorrect update of if_ierrors counter. For Rx buffer
shortage it should update if_qdrops as the buffer is reused.
o Added checks for unsupported H/W revisions and return ENXIO for
these hardwares. This is required to remove resource allocation
code in re_probe as other drivers do in device probe routine.
o Modified descriptor index manipulation macros as it's now possible
to have different number of descriptors for Rx/Tx.
o In re_start, to save a lock operation, use IFQ_DRV_IS_EMPTY before
trying to invoke IFQ_DRV_DEQUEUE. Also don't blindly call re_encap
since we already know the number of available Tx descriptors in
advance.
o Removed RL_TX_DESC_THLD which was used to reserve RL_TX_DESC_THLD
descriptors in Tx path. There is no such a limitation mentioned in
8139C+/8169/8110/8168/8101/8111 datasheet and it seems to work ok
without reserving RL_TX_DESC_THLD descriptors.
o Fix a comment for RL_GTXSTART. The register is 8bits register.
o Added comments for 8169/8139C+ hardware restrictions on descriptors.
o Removed forward declaration for "struct rl_softc", it's not needed.
o Added a new structure rl_txdesc for Tx descriptor managements and
a structure rl_rxdesc for Rx descriptor managements.
o Removed unused member variable rl_intlock in driver softc. There are
still several unused member variables which are supposed to be used
to access hardware statistics counters. But it seems that accessing
hardware counters were not implemented yet.

0xfff0 is special meaning that indicates hardware is in the
process of copying a packet into host memory. But it seems
there are other cases that hardware is busy or stuck in bad
situation even if the received frame length is not 0xfff0.
To work-around this condition, add a check that verifys that
recevied frame length is in valid range. If received length is out
of range reinitialize hardware to recover from stuck condition.

The default value is 1(102.4us). Users can change the timer value
with dev.sf.N.int_mod sysctl(8) variable/loader(8) tunable.
o bus_dma(9) conversion
- Enable 64bit DMA addressing.
- Enable 64bit descriptor format support.
- Apply descriptor ring alignment requirements(256 bytes alignment).
- Apply Rx buffer address alignment requirements(4 bytes alignment).
- Apply 4GB boundary restrictions(Tx/Rx ring and its completion ring
should live in the same 4GB address space.)
- Set number of allowable number of DMA segments to 16. In fact,
AIC-6915 doesn't have a limit for number of DMA segments but it
would be waste of Tx descriptor resource if we allow more than 16.
- Rx/Tx side bus_dmamap_load_mbuf_sg(9) support.
- Added alignment fixup code for strict-alignment architectures.
- Added endianness support code in Tx/Rx descriptor access.
With these changes sf(4) should work on all platforms.
o Don't set if_mtu in device attach, it's handled in ether_ifattach.
o Use our own callout to drive watchdog timer.
o Enable VLAN oversized frames and announce sf(4)'s VLAN capability
to upper layer.
o In sf_detach(), remove mtx_initialized KASSERT as it's not possible
to get there without initialzing the mutex. Also mark that we're
about to detaching so active bpf listeners do not panic the system.
o To reduce PCI register access cycles, Rx completion ring is
directly scanned instead of reading consumer/producer index
registers. In theory, Tx completion ring also can be directly
scanned. However the completion ring is composed of two types
completion(1 for Tx done and 1 and DMA done). So reading producer
index via register access would be more safer way to detect the
ring wrap-around.
o In sf_rxeof(), don't use m_devget(9) to align recevied frames. The
alignment is required only for strict-alignment architectures and
now the alignment is handled by sf_fixup_rx() if required. The
removal of the copy operation in fast path should increase Rx
performance a lot on non-strict-alignemnt architectures such as
i386 and amd64.
o In sf_newbuf(), don't set descriptor valid bit as sf(4) is
programmed to run with normal mode. In normal mode, the valid bit
have no meaning. The valid bit should be used only when the
hardware uses polling(prefetch) mode. The end of descriptor queue
bit could be used if needed, but sf(4) relys on auto-wrapping of
hardware on 256 descriptor queue entries so both valid and
descriptor end bit are not used anymore.
o Don't disable generation of Tx DMA completion as said in datasheet
and use the Tx DMA completion entry instead of relying on Tx done
completion entry. Also added additional Tx completion entry type
check in Tx completion handler.
o Don't blindly reset watchdog timer in sf_txeof(). sf(4) now unarm
the the watchdog only if there are no active Tx descriptors in Tx
queue.
o Don't manually update various counters in driver, instead, use
built-in MAC statistic registers to update them. The statistic
registers are updated in every second.
o Modified Tx underrun handlers to increase the threshold value
in units of 256 bytes. Previously it used to increase 16 bytes
at a time which seems to take too long to stabalize whenever Tx
underrun occurrs.
o In interrupt handler, additional check for the interrupt is
performed such that interrupts only for this device is allowed to
process descriptor rings. Because reading SF_ISR register clears
all interrtups, nuke writing to a SF_ISR register.
o Tx underrun is abonormal condition and SF_ISR_ABNORMALINTR includes
the interrupt. So there is no need to inspect the Tx underrun again
in main interrupt loop.
o Don't blindly reinitialize hardware for abnormal interrupt
condition. sf(4) reintializes the hardware only when it encounters
DMA error which requires an explicit hardware reinitialization.
o Fix a long standing bug that incorrectly clears MAC statistic
registers in sf_init_locked.
o Added strict-alignment safe way of ethernet address reprogramming
as IF_LLADDR may return unaligned address.
o Move sf_reset() to sf_init_locked in order to always reset the
hardware to a known state prior to configuring hardware.
o Set default Rx DMA, Tx DMA paramters as shown in datasheet.
o Enable PCI busmaster logic and autopadding for VLAN frames.
o Rework sf_encap.
- Previously sf(4) used to type 0 of Tx descriptor with padding
enabled to store driver private data. Emebedding private data
structures into descriptors is bad idea as the structure size
would be different between 64bit and 32bit architectures. The
type 0 descriptor allows fixed number of DMA segments in
a descriptor format and provides relatively simple interface to
manage multi-fragmented frames.
However, it wastes lots of Tx descriptors as not all frames are
fragmented as the number of allowable segments in a descriptor.
- To overcome the limitation of type 0 descriptor, switch to type
2 descriptor which allows 64bit DMA addressing and can handle
unliumited number of fragmented DMA segments. The drawback of
type 2 descriptor is in its complexity in managing descriptors
as driver should handle the end of Tx ring manually.
- Manually set Tx desciptor queue end mark and record number of
used descriptors to reclaim used descriptors in sf_txeof().
o Rework sf_start.
- Honor link up/down state before attempting transmission.
- Because sf(4) uses only one of two Tx queues, use low priority
queue instead of high one. This will remove one shift operation
in each Tx kick command.
- Cache last produder index into softc such that subsequenet Tx
operation doesn't need to access producer index register.
o Rewrote sf_stats_update to include all available MAC statistic
counters.
o Employ AIC-6915 firmware from Adaptec and implement firmware
download routine and TCP/UDP checksum offload.
Partial checksum offload support was commented out due to the
possibility of firmware bug in RxGFP.
The firmware can strip VLAN tag in Rx path but the lack of firmware
assistance of VLAN tag insertion in transmit side made it useless
on FreeBSD. Unlike checksum offload, FreeBSD requires both Tx/Rx
hardware VLAN assistance capability. The firmware may also detect
wakeup frame and can wake system up from states other than D0.
However, the lack of wakeup support form D3cold state keep me from
adding WOL capability. Also detecting WOL frame requires firmware
support but it's not yet known to me whether the firmware can
process the WOL frame.
o Changed *_ADDR_HIADDR to *_ADDR_HI to match other definitions of
registers.
o Added definitioan to interrupt moderation related constants.
o Redefined SF_INTRS to include Tx DMA done and DMA errors. Removed
Tx done as it's not needed anymore.
o Added definition for Rx/Tx DMA high priority threshold.
o Nuked unused marco SF_IDX_LO, SF_IDX_HI.
o Added complete MAC statistic register definition.
o Modified sf_stats structure to hold all MAC statistic regiters.
o Nuke various driver private padding data in Tx/Rx descriptor
definition. sf(4) no longer requires private padding. Also remove
unused padding related definitions. This greatly simplifies
descriptor manipulation on 64bit architectures.
o Becase we no longer pad driver private data into descriptor,
remove deprecated/not-applicable comments for padding.
o Redefine Rx/Tx desciptor status. sf(4) doesn't use bit fileds
anymore to support endianness.
o Import AIC-6915 firmware for GFP from Adaptec.
Make ALTQ cope with disappearing interfaces (particularly common with mpd
and netgraph in gernal). This also allows to add queues for an interface
that is not yet existing (you have to provide the bandwidth for the
interface, however).

Don't zero td_runtime when billing thread CPU usage to the process;

When thread information is requested using the thread monitoring
sysctls, export thread td_runtime instead of process rusage runtime
in kinfo_proc.
This restores the display of individual ithread and other kernel
thread CPU usage since inception in ps -H and top -SH, as well for
libthr user threads, valuable debugging information lost with the
move to try kthreads since they are no longer independent processes.
There is universal agreement that we should rewrite the process and

Note: in MFC, td_incruntime is added to the end of struc thread,

Return ESRCH when a kernel stack is queried on a process in execve() --
p_candebug() will return EAGAIN which, if the other process never

spinning in kernel while we wait is bad for countless reasons, and
particularly harmful if execve() itself is deadlocked.
Possibly we should return another error, or return a marker indicating
the thread is in execve() so it can be reported that way in userspace.

Use m_collapse(9) to collapse mbuf chains instead of relying on
shortest possible chain of mbufs of m_defrag(9). What we want is
chains of mbufs that can be safely stored to a Tx descriptor which
can have up to STGE_MAXTXSEGS mbufs. The ethernet controller does
not need to align Tx buffers on 32bit boundary. So the use of
m_defrag(9) was waste of time.
Implement WOL capability.
- Turn on WOL bits in suspend/shutdown method.
- WOL is disabled in resume routine as WOL can interfere normal
Rx operation.
- Move stge_reset() to stge_init_locked() as resetting hardware
clears configured Rx information which in turn results in
non-working Rx module after suspend/shutdown operation.
o vr(4) repocopied from sys/pci to sys/dev/vr.
Teach vr(4) to use bus_dma(9) and major overhauling to handle link
state change and reliable error recovery.
o Moved vr_softc structure and relevant macros to header file.
o Use PCIR_BAR macro to get BARs.
o Implemented suspend/resume methods.
o Implemented automatic Tx threshold configuration which will be
activated when it suffers from Tx underrun. Also Tx underrun
will try to restart only Tx path and resort to previous
full-reset(both Rx/Tx) operation if restarting Tx path have failed.
o Removed old bit-banging MII interface. Rhine provides simple and
efficient MII interface. While I'm here show PHY address and PHY
register number when its read/write operation was failed.
o Define VR_MII_TIMEOUT constant and use it in MII access routines.
o Always honor link up/down state reported by mii layers. The link
state information is used in vr_start() to determine whether we
got a valid link.
o Removed vr_setcfg() which is now handled in vr_link_task(), link
state taskqueue handler. When mii layer reports link state changes
the taskqueue handler reprograms MAC to reflect negotiated duplex
settings. Flow-control changes are not handled yet and it should
be revisited when mii layer knows the notion of flow-control.
o Added a new sysctl interface to get statistics of an instance of
the driver.(sysctl dev.vr.0.stats=1)
o Chip name was renamed to reflect the official name of the chips
described in VIA Rhine I/II/III datasheet.
REV_ID_3065_A -> REV_ID_VT6102_A
REV_ID_3065_B -> REV_ID_VT6102_B
REV_ID_3065_C -> REV_ID_VT6102_C
REV_ID_3106_J -> REV_ID_VT6105_A0
REV_ID_3106_S -> REV_ID_VT6105M_A0
The following chip revisions were added.
#define REV_ID_VT6105_B0 0x83
#define REV_ID_VT6105_LOM 0x8A
#define REV_ID_VT6107_A0 0x8C
#define REV_ID_VT6107_A1 0x8D
#define REV_ID_VT6105M_B1 0x94
o Always show chip revision number in device attach. This shall help
identifying revision specific issues.
o Check whether EEPROM reloading is complete by inspecting the state
of VR_EECSR_LOAD bit. This bit is self-cleared after the EEPROM
reloading. Previously vr(4) blindly spins for 200us which may/may
not enough to complete the EEPROM reload.
o Removed if_mtu setup. It's done in ether_ifattach().
o Use our own callout to drive watchdog timer.
o In vr_attach disable further interrupts after reset. For VT6102 or
newer hardwares, diable MII state change interrupt as well because
mii state handling is done by mii layer.
o Add more sane register initialization for VT6102 or newer chips.
- Have NIC report error instead of retrying forever.
- Let hardware detect MII coding error.
- Enable MODE10T mode.
- Enable memory-read-multiple for VT6107.
o PHY address for VT6105 or newer chips is located at fixed address 1.
For older chips the PHY address is stored in VR_PHYADDR register.
Armed with these information, there is no need to re-read
VR_PHYADDR register in miibus handler to get PHY address. This
saves one register access cycle for each MII access.
o Don't reprogram VR_PHYADDR register whenever access to a register
located at a PHY address is made. Rhine fmaily allows reprogramming
PHY address location via VR_PHYADDR register depending on
VR_MIISTAT_PHYOPT bit of VR_MIISTAT register. This used to lead
numerous phantom PHYs attached to miibus during phy probe phase and
driver used to limit allowable PHY address in mii register accessors
for certain chip revisions. This removes one more register access
cycle for each MII access.
o Correctly set VLAN header length.
o bus_dma(9) conversion.
- Limit DMA access to be in range of 32bit address space. Hardware
doesn't support DAC.
- Apply descriptor ring alignment requirements(16 bytes alignment)
- Apply Rx buffer address alignment requirements(4 bytes alignment)
- Apply Tx buffer address alignment requirements(4 bytes alignment)
for Rhine I chip. Rhine II or III has no Tx buffer address
alignment restrictions, though.
- Reduce number of allowable number of DMA segments to 8.
- Removed the atomic(9) used in descriptor ownership managements
as it's job of bus_dmamap_sync(9).
With these change vr(4) should work on all platforms.
o Rhine uses two separated 8bits command registers to control Tx/Rx
MAC. So don't access it as a single 16bit register.
o For non-strict alignment architectures vr(4) no longer require
time-consuming copy operation for received frames to align IP
header. This greatly improves Rx performance on i386/amd64
platforms. However the alignment is still necessary for
strict-alignment platforms(e.g. sparc64). The alignment is handled
in new fuction vr_fixup_rx().
o vr_rxeof() now rejects multiple-segmented(fragmented) frames as
vr(4) is not ready to handle this situation. Datasheet said nothing
about the reason when/why it happens.
o In vr_newbuf() don't set VR_RXSTAT_FIRSTFRAG/VR_RXSTAT_LASTFRAG
bits as it's set by hardware.
o Don't pass checksum offload information to upper layer for
fragmented frames. The hardware assisted checksum is valid only
when the frame is non-fragmented IP frames. Also mark the checksum
is valid for corrupted frames such that upper layers doesn't need
to recompute the checksum with software routine.
o Removed vr_rxeoc(). RxDMA doesn't seem to need to be idle before
sending VR_CMD_RX_GO command. Previously it used to stop RxDMA
first which in turn resulted in long delays in Rx error recovery.
o Rewrote Tx completion handler.
- Always check VR_TXSTAT_OWN bit in status word prior to
inspecting other status bits in the status word.
- Collision counter updates were corrected as VT3071 or newer
ones use different bits to notify collisions.
- Unlike other chip revisions, VT86C100A uses different bit to
indicate Tx underrun. For VT3071 or newer ones, check both
VR_TXSTAT_TBUFF and VR_TXSTAT_UDF bits to see whether Tx
underrun was happend. In case of Tx underrun requeue the failed
frame and restart stalled Tx SM. Also double Tx DMA threshold
size on each failure to mitigate future Tx underruns.
- Disarm watchdog timer only if we have no queued packets,
otherwise don't touch watchdog timer.
o Rewrote interrupt handler.
- status word in Tx/Rx descriptors indicates more detailed error
state required to recover from the specific error. There is no
need to rely on interrupt status word to recover from Tx/Rx
error except PCI bus error. Other event notifications like
statistics counter overflows or link state events will be
handled in main interrupt handler.
- Don't touch VR_IMR register if we are in suspend mode. Touching
the register may hang the hardware if we are in suspended state.
Previously it seems that touching VR_IMR register in interrupt
handler was to work-around panic occurred in system shutdown
stage on SMP systems. I think that work-around would hide
root-cause of the panic and I couldn't reproduce the panic
with multiple attempts on my box.
o While padding space to meet minimum frame size, zero the pad data
in order to avoid possibly leaking sensitive data.
o Rewrote vr_start_locked().
- Don't try to queue packets if number of available Tx descriptors
are short than that of required one.
o Don't reinitialize hardware whenever media configuration is
changed. Media/link state changes are reported from mii layer if
this happens and vr_link_task() will perform necessary changes.
o Don't reinitialize hardware if only PROMISC bit was changed. Just
toggle the PROMISC bit in hardware is sufficient to reflect the
request.
o Rearrganed the IFCAP_POLLING/IFCAP_HWCSUM handling in vr_ioctl().
o Generate Tx completion interrupts for every VR_TX_INTR_THRESH-th
frames. This reduces Tx completion interrupts under heavy network
loads.
o Since vr(4) doesn't request Tx interrupts for every queued frames,
reclaim any pending descriptors not handled in Tx completion
handler before actually firing up watchdog timeouts.
o Added vr_tx_stop()/vr_rx_stop() to wait for the end of active
TxDMA/RxDMA cycles(draining). These routines are used in vr_stop()
to ensure sane state of MAC before releasing allocated Tx/Rx
buffers. vr_link_task() also takes advantage of these functions to
get to idle state prior to restarting Tx/Rx.
o Added vr_tx_start()/vr_rx_start() to restart Rx/Tx. By separating
Rx operation from Tx operation vr(4) no longer need to full-reset
the hardware in case of Tx/Rx error recovery.
o Implemented WOL.
o Added VT6105M specific register definitions. VT6105M has the
following hardware capabilities.
- Tx/Rx IP/TCP/UDP checksum offload.
- VLAN hardware tag insertion/extraction. Due to lack of information
for getting extracted VLAN tag in Rx path, VLAN hardware support
was not implemented yet.
- CAM(Content Addressable Memory) based 32 entry perfect multicast/
VLAN filtering.
- 8 priority queues.
o Implemented CAM based 32 entry perfect multicast filtering for
VT6105M. If number of multicast entry is greater than 32, vr(4)
uses traditional hash based filtering.
o Reflect real Tx/Rx descriptor structure. Previously vr(4) used to
embed other driver (private) data into these structure. This type
of embedding make it hard to work on LP64 systems.
o Removed unused vr_mii_frame structure and MII bit-baning
definitions.
o Added new PCI configuration registers that controls mii operation
and mode selection.
o Reduced number of Tx/Rx descriptors to 128 from 256. From my
testing, increasing number of descriptors above than 64 didn't help
increasing performance at all. Experimentations show 128 Rx
descriptors seems to help a lot reducing Rx FIFO overruns under
high system loads. It seems the poor Tx performance of Rhine
hardwares comes from the limitation of hardware. You wouldn't
satuarte the link with vr(4) no matter how fast CPU/large number of
descriptors are used.
o Added vr_statistics structure to hold various counter values.
Add a new function is_default_interface() which determines if this
interface is one with the default route (or there isn't one). Use it to
decide if we should adjust the default route and /etc/resolv.conf.
Fix the delete of the default route. The if statement was totally bogus
and the delete only worked due to a typo. [1]

Add two new sysctls in support of the forthcoming procstat(1) to support
its -f and -v arguments:
kern.proc.filedesc - dump file descriptor information for a process, if
debugging is permitted, including socket addresses, open flags, file
offsets, file paths, etc.
kern.proc.vmmap - dump virtual memory mapping information for a process,
if debugging is permitted, including layout and information on
underlying objects, such as the type of object and path.
These provide a superset of the information historically available
through the now-deprecated procfs(4), and are intended to be exported
in an ABI-robust form.
stack.h:1.3, redzone.c:1.2 from HEAD to RELENG_7:
Modify stack(9) stack_print() and stack_sbuf_print() routines to use new
linker interfaces for looking up function names and offsets from
instruction pointers. Create two variants of each call: one that is
"DDB-safe" and avoids locking in the linker, and one that is safe for
use in live kernels, by virtue of observing locking, and in particular
safe when kernel modules are being loaded and unloaded simultaneous to
their use. This will allow them to be used outside of debugging
contexts.
Modify two of three current stack(9) consumers to use the DDB-safe
interfaces, as they run in low-level debugging contexts, such as inside
lockmgr(9) and the kernel memory allocator.
Update man page.
The kernel linker includes a number of utility functions to look up symbol
information in support of DDB(4); these functions bypass normal linker
locking as they may run in contexts where locking is unsafe (such as the
kernel debugger).
Add a new interface linker_ddb_search_symbol_name(), which looks up a
symbol name and offset given an address, and also
linker_search_symbol_name() which does the same but *does* follow the
locking conventions of the linker.
Unlike existing functions, these functions place the name in a
caller-provided buffer, which is stable even after linker locks have been
released. These functions will be used in upcoming revisions to stack(9)
to support kernel stack trace generation in contexts as part of a live,
rather than suspended, kernel.
audit_private.h:1.17 from HEAD to RELENG_7:

Calling RequestSupplementAdapterInfo before RequestAdapterInfo appears
to trip a bug causing the latter to return a zeroed struct
aac_adapter_info. This causes two issues. One is cosmetic only --
a verbose boot prints information about the controller, and shows all
zero:
aac0: Unknown processor 0MHz, 0MB memory (0MB cache, 0MB execution),
unknown battery platform
The second problem is that the firmware version information is stored
away for aac_rev_check, for userland tools (like aaccli) to query via
the FSACTL_MINIPORT_REV_CHECK and FSACTL_LNX_MINIPORT_REV_CHECK ioctls.
When aaccli encounters this issue it prints
Command Error: <The current AFAAPI.DLL is too old to work with the
current controller software.>
Move the RequestSupplementAdapterInfo call after RequestAdapterInfo,
which seems to fix both problems.

Rather than copying out the full audit trigger record, which includes
a queue entry field, just copy out the unsigned int that is the trigger
message. In practice, auditd always requested sizeof(unsigned int), so
the extra bytes were ignored, but copying them out was not the intent.
Replace somewhat awkward audit trail rotation scheme, which involved the
global audit mutex and condition variables, with an sx lock which protects
the trail vnode and credential while in use, and is acquired by the system
call code when rotating the trail. Previously, a "message" would be sent
to the kernel audit worker, which did the rotation, but the new code is
simpler and (hopefully) less error-prone.

- Switch from timeval to bintime, to use 1/(2^20) of seconds instead of
microseconds. It allows to use bit shifts instead of some heavy 64bit
mul/div math operations.
- Account all node stats at the shape mode.
- Do not check destination hook presence, it will be done by netgraph.
- Use u_int instead of int in some places to simplify type conversions.
- Use NG_SEND_DATA_ONLY() macro instead of selfmade equivalent.
Add a /S mode to DDB "ex" command, which interprets and prints the
value at the requested address as a symbol. For example, "ex /S
aio_swake" prints the name of the function currently registered in
via aio_swake hook.
The change as committed differs slightly from the patch in the PR,
as I force the size of the retrieved value (and the automatic
address increment) to be sizeof(void *). This seems to provide
the most useful auto-increment behavior, and defaults using the
default size (4), which is not sizeof(void *) on 64-bit platforms.

db_textdump.c:1.1, ddb.h:1.46, kern_shutdown.c:1.187 from HEAD to
RELENG_7:
Add textdump(4) facility, which provides an alternative form of kernel
dump using mechanically generated/extracted debugging output rather than
a simple memory dump. Current sources of debugging output are:
- DDB output capture buffer, if there is captured output to save
- Kernel message buffer
- Kernel configuration, if included in kernel
- Kernel version string
- Panic message
Textdumps are stored in swap/dump partitions as with regular dumps, but
are laid out as ustar files in order to allow multiple parts to be stored
as a stream of sequentially written blocks. Blocks are written out in
reverse order, as the size of a textdump isn't known a priori. As with
regular dumps, they will be extracted using savecore(8).
One new DDB(4) command is added, "textdump", which accepts "set",
"unset", and "status" arguments. By default, normal kernel dumps are
generated unless "textdump set" is run in order to schedule a textdump.
It can be canceled using "textdump unset" to restore generation of a
normal kernel dump.
Several sysctls exist to configure aspects of textdumps;
debug.ddb.textdump.pending can be set to check whether a textdump is
pending, or set/unset in order to control whether the next kernel dump
will be a textdump from userspace.
While textdumps don't have to be generated as a result of a DDB script
run automatically as part of a kernel panic, this is a particular useful
way to use them, as instead of generating a complete memory dump, a
simple transcript of an automated DDB session can be captured using the
DDB output capture and textdump facilities. This can be used to
generate quite brief kernel bug reports rich in debugging information
but not dependent on kernel symbol tables or precisely synchronized
source code. Most textdumps I generate are less than 100k including
the full message buffer. Using textdumps with an interactive debugging
session is also useful, with capture being enabled/disabled in order to
record some but not all of the DDB session.

ddb.h:1.1, ddb_script.c:1.1 from HEAD to RELENG_7:
Add command-line tool ddb(8), which allows DDB(4) scripts to be

are awkward to use directly, this provides an easier-to-use
interface.
db_lex.h:1.15, db_main.c:1.7, db_script.c:1.1-1.2, ddb.h:1.45 from HEAD

Add a simple scripting facility to DDB(4), allowing the user to
define a set of named scripts. Each script consists of a list of DDB
commands separated by ";"s that will be executed verbatim. No higher
level language constructs, such as branching, are provided for:
scripts are executed by sequentially injecting commands into the DDB
input buffer.
Four new commands are present in DDB: "run" to run a specific script,
"script" to define or print a script, "scripts" to list currently
defined scripts, and "unscript" to delete a script, modeled on shell
alias commands. Scripts may also be manipulated using sysctls in the
debug.ddb.scripting MIB space, although users will prefer to use the
soon-to-be-added ddb(8) tool for usability reasons.
Scripts with certain names are automatically executed on various DDB
events, such as entering the debugger via a panic, a witness error,
watchdog, breakpoint, sysctl, serial break, etc, allowing customized
handling.

Now it returns last nonzero result from all call chain results in this request.
As soon as this improvement gives reliable error reporting, it is now possible
to remove dirty workaround in ng_socket, made to return ENOBUFS error statuses
of request-response operations. That workaround was responsible for returning
ENOBUFS errors to completely unrelated requests working at the same time
on socket.
Enhance realpath(1) in a number of ways:
- Allow realpath to accept multiple paths on the command line.
- Add -q to suppress warnings if some paths can't be processed, and use
getopt(3) to process flags.
- Print the path being requested rather than a possibly partially
processed path when a failure occurs so that you can tell which of
several passed paths did fail.

Don't auto-start or allow extattrctl for UFS2 file systems, as UFS2 has
native extended attributes. This didn't interfere with the operation of
UFS2 extended attributes, but the code shouldn't be running for UFS2.
The possibly interruptible msleep in coda_call() means well, but is
fundamentally fairly confused about how signals work and when it is
appropriate for upcalls to be interrupted. In particular, we should
be exempting certain upcalls from interruption, we should not always
eventually time out sleeping on a upcall, and we should not be
interrupting the sleep for certain signals that we currently are
(including SIGINFO). This code needs to be reworked in the style of
NFS interruptible mounts.
Use sbuf routines to construct core dump filenames rather than custom
string buffer handling, making the code both easier to read and more
robust against string-handling bugs.
In Coda, flush the attribute cache for a cnode when its fid is
changed, as its synthesized inode number may have changed and we
want stat(2) to pick up the new inode number.
Update cache flushing behavior in light of recent namecache and
access cache improvements:
- Flush just access control state on CODA_PURGEUSER, not the full
namecache for /coda.
- When replacing a fid on a cnode as a result of, e.g.,
reintegration after offline operation, we no longer need to
purge the namecache entries associated with its vnode.
RELENG_7:
Implement a rudimentary access cache for the Coda kernel module,
modeled on the access cache found in NFS, smbfs, and the Linux coda
module. This is a positive access cache of a single entry per file,
tracking recently granted rights, but unlike NFS and smbfs,
supporting explicit invalidation by the distributed file system.
For each cnode, maintain a C_ACCCACHE flag indicating the validity
of the cache, and a cached uid and mode tracking recently granted
positive access control decisions.
Prefer the cache to venus_access() in VOP_ACCESS() if it is valid,
and when we must fall back to venus_access(), update the cache.
Allow Venus to clear the access cache, either the whole cache on
CODA_FLUSH, or just entries for a specific uid on CODA_PURGEUSER.
Unlike the Coda module on Linux, we don't flush all entries on a
user purge using a generation number, we instead walk present
cnodes and clear only entries for the specific user, meaning it is
somewhat more expensive but won't hit all users.
Since the Coda module is agressive about not keeping around
unopened cnodes, the utility of the cache is somewhat limited for
files, but works will for directories. We should make Coda less
agressive about GCing cnodes in VOP_INACTIVE() in order to improve
the effectiveness of in-kernel caching of attributes and access
rights.

coda_namecache.c:1.26, coda_namecache.h:1.15, Makefile:1.18,
from HEAD to RELENG_7:
Rather than having the Coda module use its own namecache, use the global
VFS namecache, as is done by the Coda module on Linux. Unlike the Coda
namecache, the global VFS namecache isn't tagged by credential, so use
ore conservative flushing behavior (for now) when CODA_PURGEUSER is
issued by Venus.
This improves overall integration with the FreeBSD VFS, including
allowing __getcwd() to work better, procfs/procstat monitoring, and so
on. This improves shell behavior in many cases, and improves ".."
handling. It may lead to some slowdown until we've implemented a
specific access cache, which should net improve performance, but in the
mean time, lookup access control now always goes to Venus, whereas
previously it didn't.
Add an option to register DUN (Dial-Up Networking) service on the same
RFCOMM channel if needed. There is really no good reason to not to support
this. AT-command exchange can be faked with chat script in ppp.conf.
Padding after EOL option must be zeros according to RFC793 but
the NOPs used are 0x01.
While we could simply pad with EOLs (which are 0x00), rather use an
explicit 0x00 constant there to not confuse poeple with 'EOL padding'.
Put in a comment saying just that.

because of more people reporting problems on net@
stdio is currently limited to file descriptors not greater than
{SHRT_MAX}, so {STREAM_MAX} should be no greater than that. (This
does not exactly meet the letter of POSIX but comes reasonably close
to it in spirit.)
When the state of the interface changes rapidly enough there is a race
where dhclient is in the process of exiting due to the link going down
when the link coming up causes devd to try and start a new one. This
results is the link being up, but no dhclient running.
Work around this race by checking a second time after a one second delay
before refusing to start a dhclient instance due to one already being
running.
During PREINIT, when giving the interface the address 0.0.0.0, do it as an
alias to avoid distrubing other addresses.

coda_vfsops.c:1.74, coda_vnops.c:1.87, coda_vnops.h:1.20 from HEAD
to RELENG_7:
The Coda module was originally ported to NetBSD from Mach by rvb, and
then later to FreeBSD. Update various NetBSD-related comments: in some
cases delete them because they don't appply, in others update to say
FreeBSD as they still apply but in FreeBSD (and might for that matter
no longer apply on NetBSD), and flag one case where I'm not sure
whether it applies.
Before invoking vnode operations on cache vnodes, acquire the vnode
locks of those vnodes. Probably, Coda should do the same lock sharing/
pass-through that is done for nullfs, but in the mean time this ensures
that locks are adequately held to prevent corruption of data structures
in the cache file system.
Assuming most operations came from the top layer of Coda and weren't
performed directly on the cache vnodes, in practice this corruption was
relatively unlikely as the Coda vnode locks were ensuring exclusive
access for most consumers.
This causes WITNESS to squeal like a pig immediately when Coda is used,
rather than waiting until file close; I noticed these problems because
of the lack of said squealing.
NB: Because WITNESS in RELENG_7 doesn't yet support lockmgr, said
squealing doesn't yet happen in RELENG_7, but will do if/when lockmgr
grows support for WITNESS there.
Remove undefined coda excluded by #if 1 #else, which previously protected

When redrawing an input line, count backspaces to get to the beginning of

Otherwise, we may overshoot, overwriting a bit of the previous line and
failing to fully overwrite the current line.

sctp_input.c:1.67, sctp_peeloff.c:1.17, sctputil.c:1.73,
socketvar.h:1.161 from HEAD to RELENG_7:
Correct two problems relating to sorflush(), which is called to flush
read socket buffers in shutdown() and close():
- Call socantrcvmore() before sblock() to dislodge any threads that
might be sleeping (potentially indefinitely) while holding sblock(),
such as a thread blocked in recv().
- Flag the sblock() call as non-interruptible so that a signal
delivered to the thread calling sorflush() doesn't cause sblock() to
fail. The sblock() is required to ensure that all other socket
consumer threads have, in fact, left, and do not enter, the socket
buffer until we're done flushin it.
To implement the latter, change the 'flags' argument to sblock() to
accept two flags, SBL_WAIT and SBL_NOINTR, rather than one M_WAITOK
flag. When SBL_NOINTR is set, it forces a non-interruptible sx
acquisition, regardless of the setting of the disposition of SB_NOINTR
on the socket buffer; without this change it would be possible for
another thread to clear SB_NOINTR between when the socket buffer mutex
is released and sblock() is invoked.

tcp_usrreq.c:1.313 removed tcbinfo locking from tcp_usr_accept(), which
while in principle a good idea, opened us up to a race inherrent to
the syncache's direct insertion of incoming TCP connections into the
"completed connection" listen queue, as it transpires that the socket
is inserted before the inpcb is fully filled in by syncache_expand().
The bug manifested with the occasional returning of 0.0.0.0:0 in the
address returned by the accept() system call, which occurred if accept
managed to execute tcp_usr_accept() before syncache_expand() had copied
the endpoint addresses into inpcb connection state.
Re-add tcbinfo locking around the address copyout, which has the effect
of delaying the copy until syncache_expand() has finished running, as
it is run while the tcbinfo lock is held. This is undesirable in that
it increases contention on tcbinfo further, but a more significant
change will be required to how the syncache inserts new sockets in
order to fix this and keep more granular locking here. In particular,
either more state needs to be passed into sonewconn() so that
pru_attach() can fill in the fields *before* the socket is inserted, or
the socket needs to be inserted in the incomplete connection queue
until it is actually ready to be used.

ffs_balloc_ufsX() routines, in the case of recovering from the failed

that could lead to the softupdate inconsistencies in the case of the

Rearrange the recover code to do the ffs_blkfree() after the second
ffs_syncvnode(), that clears the pointers chain.
The ffs_balloc() routines, whan allocating the indirect blocks for
the inode, do the rollback in case the allocation failed (due to
insufficient free space or quota limits). But, the code does leaves the
buffers corresponding to the inoirect blocks on the vnode bufobj list.
This causes several assertion failures (for instance, "ffs_truncate3"
in ffs_truncate()) to fail, and could result in the indirect block
aliasing problem, like writing the context of such blocks to random
disk location.

positives returned by __gthread_active_p() for non-threaded programs
cause the exception handling implementation GCC uses in this case to
crash. This is because GCC assumes that the POSIX threading functions
actually work when __gthread_active_p() returns 1 while in fact the
corresponding stubs in libc just immediately return.
Given that __gthread_active_p() is also used in a couple of other
places besides exception handling, this bug has great potential to
also cause problems in other areas and on all archs.
This is committed to RELENG_7 directly in order to get a fix into
RELENG_7_0 as soon as possible while allowing to loop the official
fix back into the vendor branch and not taking gthr-posix.h off the
vendor branch in HEAD.

Do not allow the SNPSTTY ioctl for the snoop device that has a tty
attached. Otherwise, the snp->snp_tty would be overwritten, while the
tty line discipline still set to the snpdisc. Then snplwrite() causes
panic because ttytosnp() cannot find the snp. (And do it at the proper
place, from rev. 1.107).
MFC rev. 1.107:
The snp_target == NULL implies the snp_tty == NULL. Remove the code
that is put under snp_target == NULL and snp_tty != NULL clause.
In snpclose(), do the snp_detach() before scheduling the snp device
destruction. Otherwise, after the return from snpclose(), the snp
device is already removed from the snp_list, but tty is still in
snooped state. Any attempt to do i/o on such tty cause panic because
ttytosnp() returns NULL.

How it's done currently, the kernel domain could be allocated for a

So switch back to the previous way we did things, set the first available

sys/arm/include/asmacros.h rev 1.7
sys/arm/include/atomic.h rev 1.23
Close a race.
The RAS implementation would set the end address, then the start
address. These were used by the kernel to restart a RAS sequence if
it was interrupted. When the thread switching code ran, it would
check these values and adjust the PC and clear them if it did.
However, there's a small flaw in this scheme. Thread T1, sets the end
address and gets preempted. Thread T2 runs and also does a RAS
operation. This resets end to zero. Thread T1 now runs again and
sets start and then begins the RAS sequence, but is preempted before
the RAS sequence executes its last instruction. The kernel code that
would ordinarily restart the RAS sequence doesn't because the PC isn't
between start and 0, so the PC isn't set to the start of the sequence.
So when T1 is resumed again, it is at the wrong location for RAS to
produce the correct results. This causes the wrong results for the
atomic sequence.
The window for the first race is 3 instructions. The window for the
second race is 5-10 instructions depending on the atomic operation.
This makes this failure fairly rare and hard to reproduce.
Mutexs are implemented in libthr using atomic operations. When the
above race would occur, a lock could get stuck locked, causing many
downstream problems, as you might expect.
Also, make sure to reset the start and end address when doing a syscall, or
a malicious process could set them before doing a syscall.

with the current code can re-enable it but it will require tweaking
conf files and unifdef'ing it. By removing it now before the release,
we avoid having to support the current allocation protocol in future

Remove hacks from the NFSv2/3 client intended to handle a lack of a
server-side RPC retranmission cache for non-idempotent operations: these
hacks substituted 0 (success) for the expected EEXIST in the event that
a target name already existed for LINK, SYMLINK, and MKDIR operations,
under the assumption that EEXIST represented a second application of the
original RPC rather than a true failure.
Background: certain NFS operations (in this case, LINK, SYMLINK, and
MKDIR) are not idempotent, as they leave behind persisting state on the
server that prevents them from being replayed without an error;if an UDP
RPC reply is lost leading to a retransmission by theclient, the second
reply will return EEXIST rather than success, asthe new object has
already been created. The NFS client previouslysilently mapped the
EEXIST return into success to paper over thisproblem.
However, in all modern NFS server implementations, a reply cache is kept
in order to retransmit the original reply to a retransmitted request,
rather than performing the operation a second time, allowing this hack
to be avoided. This allows link()-based filelocking over NFS to operate
correctly, as an application requestingthe creation of a new link for a
file to tell if it succeededatomically or not.
Other NFS clients, including Solaris and Linux, generally follow this
behavior for the same reasons. Most clients also now default to TCP,
which also helps avoid the issue of retransmitted but non-idempotent
requests in most cases.

strees2 suite, to quote his letter, this change:
1. It removes the tn_lookup_dirent stuff. I think this cannot be fixed,
because nothing protects vnode/tmpfs node between lookup is done, and
actual operation is performed, in the case the vnode lock is dropped.
At least, this is the case with the from vnode for rename.
For now, we do the linear lookup in the parent node. This has its own
drawbacks. Not mentioning speed (that could be fixed by using hash), the
real problem is the situation where several hardlinks exist in the dvp.
But, I think this is fixable.
2. The patch restores the VV_ROOT flag on the root vnode after it became
reclaimed and allocated again. This fixes MPASS assertion at the start
of the tmpfs_lookup() reported by many.

The kernel uses two ways to write data on a pipe:
o buffered write, for chunks smaller than PIPE_MINDIRECT bytes
o direct write, for everything else
A call to writev(2) may receive struct iov of various size and the
kernel may have to switch from one solution to the other. Before doing
this, it must wake reader processes and any select/poll/kqueue up.
This commit fixes a bug where select/poll/kqueue are not triggered
when switching from buffered write to direct write. It adds calls to
pipeselwakeup().

- When we process an association, we expect the tag chosen

In theory this should have caused almost all assoc not

Add support for RealTek RTL8211B(L) PHY. It's based on the patch
made by Michael Eisele and the patch was slightly modified by me.
With this change several NVIDIA ethernet controllers(e.g. MCP61)
works.
RTL8211B(L) is RealTek's new gigabit PHY. The PHY has several
features including crossover correction, polarity correction as
well as supporting triple speed(10/100/1000bps). Data transfer
between MAC and PHY is via RGMII for 1000baseT, MII for
10baseT/100baseTX.
Unfortunately, RealTek used the same model number for RTL8211B(L)
PHY so there is no way to discriminate between RTL8211B(L) and its
predecessors. ATM RTL8211B uses revision number 2 so checking the
revision number seems to be only way to identify it.

- Fix the handling of R_SPARC_OLO10, which is a bit of a special case
in the way we implement handling of relocations.
As for the kernel part this fixes the loading of lots of modules,
which failed to load due to unresolvable symbols when built after
the GCC 4.2.0 import. This wasn't due to a change in GCC itself
though but one of several changes in configuration done along the
import. Specfically, HAVE_AS_REGISTER_PSEUDO_OP, which causes GCC
to denote global registers used for scratch purposes and in turn
GAS uses R_SPARC_OLO10 relocations for, is now defined.
While at it replace some more ELF_R_TYPE which should have been
ELF64_R_TYPE_ID but didn't cause problems so far.
- Sync a sanity check between kernel and rtld(1) and change it to be
maintenance free regarding the type used for the lookup table.
- Sprinkle const on lookup tables.
- Use __FBSDID.

NFS MP scaling changes.
- Eliminate the hideous nfs_sndlock that serialized NFS/TCP request senders
thru the sndlock.
- Institute a new nfs_connectlock that serializes NFS/TCP reconnects. Add
logic to wait for pending request senders to finish sending before
reconnecting. Dial down the sb_timeo for NFS/TCP sockets to 1 sec.
- Break out the nfs xid manipulation under a new nfs xid lock, rather than
over loading the nfs request lock for this purpose.
- Fix some of the locking in nfs_request.
Many thanks to Kris Kennaway for his help with this and for initiating the

Not all VIA Rhine chips support 256 register space. So touching
VR_STICKHW register would result in unexpected results on these
hardwares. wpaul said the following for the issue.
The vr_attach() routine unconditionally does this for all supported
chips:
/*
* Windows may put the chip in suspend mode when it
* shuts down. Be sure to kick it in the head to wake it
* up again.
*/
VR_CLRBIT(sc, VR_STICKHW, (VR_STICKHW_DS0|VR_STICKHW_DS1));
The problem is, the VR_STICKHW register is not valid on all Rhine
devices. The VT86C100A chip, which is present on the D-Link DFE-530TX
boards, doesn't support power management, and its register space is
only 128 bytes wide. The VR_STICKHW register offset falls outside this
range. This may go unnoticed in most scenarios, but if you happen to have
another PCI device in your system which is assigned the register
space immediately after that of the Rhine, the vr(4) driver will
incorrectly stomp it. In my case, the BIOS on my test board decided
to put the register space for my PRO/100 ethernet board right next
to the Rhine, and the Rhine driver ended up clobbering the IMR register
of the PRO/100 device. (Long story short: the board kept locking up on
boot. Took me the better part of the morning suss out why.)
The strictly correct thing to do would be to check the PCI config space
to make sure the device supports the power management capability and only
write to the VR_STICKHW register if it does.
Instead of inspecting chip revision numbers for the availability of
VR_STICKHW register, check the existence of power management capability
of the hardware as wpaul suggested.

The D compiler produces programs using the native data model of the operating system kernel. You can use the \fBisainfo\fR\fB-b\fR command to determine the current operating system data model. If the \fB-32\fR option is specified, \fBdtrace\fR forces
the D compiler to compile a D program using the 32-bit data model. If the \fB-64\fR option is specified, \fBdtrace\fR forces the D compiler to compile a D program using the 64-bit data model. These options are typically not required as \fBdtrace\fR selects the
native data model as the default. The data model affects the sizes of integer types and other language properties. D programs compiled for either data model can be executed on both 32-bit and 64-bit kernels. The \fB-32\fR and \fB-64\fR options also determine the ELF file format

Permit probe descriptions that match zero probes. If the \fB-Z\fR option is not specified, \fBdtrace\fR reports an error and exits if any probe descriptions specified in D program files (\fB-s\fR option) or on the command line (\fB-P\fR, \fB-m\fR, \fB-f\fR, \fB-n\fR, or \fB-i\fR options) contain descriptions that do not match any known probes.

You can specify zero or more additional arguments on the \fBdtrace\fR command line to define a set of macro variables (\fB$1\fR, \fB$2\fR, and so forth). The additional arguments can be used in D programs specified using the \fB-s\fR option
or on the command line. The use of macro variables is described further in the \fISolaris Dynamic Tracing Guide\fR.
