For objects without a TLS segment, tlsindex is zero. tls_get_addr_slow()
then reads dtv_slots[-1], which is dtv_size, and returns it as the TLS
address. Set dlpi_tls_data to NULL for such objects instead.

Without it, LLVM libunwind doesn't know where to stop when unwinding the
main thread, so it uses a stale LR as the return address and crashes.
Our libunwind doesn't do that since 5866c369e4 reverted it, but
programs that bundle their own copy, like ClickHouse, are hit by it.

The setting of _TTY ran afoul of set -e.
Also the handling of Myname blew up if debug.sh included by
a login sheel (eg in .profile).
For non-posix shell, leave false alone if it is a builtin.
Complete the controls with -v "values":
sh ./safe_eval.sh set_var -a "knob" -v "no yes" knob=yes knob=no knob=ok ok=yes

safe_var_set can be used to safely handle var=val args from command line.
eg.

# safe_var_set will only eval if
# both var and value are sane.

mountd exits if it cannot read any exports files. Requiring
/etc/exports, however, unconditionally stops mountd from starting on a
server that exports ZFS datasets only (/etc/zfs/exports).
Let sbin/mountd handle requirements itself, instead of hardcoding
/etc/exports, which is also wrong, because different files can be
specified in mountd_flags.
This patch also works with nfsv4_server_enable="YES", by preserving the
behavior of failing to start if there is no "V4:" line in the exports
file, which is missing by default on ZFS-only exports.

Drop support for queries and commands that are not supported by ACPI's

The original purpose of this daemon was to route power management
requests to userspace, e.g. when the suspend button was pressed, the
APM driver posted an event read by apmd(8) that would invoke zzz(8) to
suspend. However, on ACPI systems this is handled by devd(8) events
instead and running apmd(8) in addition just adds extra complexity.
This probably should have been axed when the APM BIOS support was
retired in commit 8c576a279e.

Incorrect ELF might have PT_NOTE slightly larger than the needed to
contain all notes, and the PT_NOTE size could be larger than one page.
Then rtld mmaps just the notes bytes to parse. After the last note,
we iterate past the mapped region trying to read the Elf_Note header.
This was found in wild.
Require full elf note to fit into the [start_note, end_note) region to
continue the parsing. Check it in stages, first verifying the Elf_Note
header structure fits, to be able to read the name and data length.
After that, check the whole note against limit.

The default on my laptop is annoyingly bright, and this is a useful
feature to mitigate that. The backlight script is largely a copy of the
mixer service which provides the same value for mixers, but this one is
specifically dependant on kld to allow DRM drivers a chance to attach.
Note that it's off by default to avoid interference with DEs, and
document the capability in backlight(8). Set backlight_enable=YES in

This patch adds a new nfs_client_rdma_enable variable
to /etc/rc.d/nfsclient to enable the client side of
NFS over RDMA. The client side of NFS over RDMA
requires the nfsclrdma.ko module, which is still under
test/review.
I wanted to get the "glue" into main so that others
could test the module more easily. Avaliability of
the module will be announced on freebsd-current@ soon.
It should not affect non-RDMA operation.
I've specified a long MFC, since the module still
requires extensive testing and, hopefully, a review.

In VM and cloud environments it is often possible to enlarge virtual
disks; this can be useful, for example, if a system is launched with a
small root disk and it later becomes clear that more space is needed.
On kernels which support run-time resizing of disks (for NVMe, this was
added in November 2025; some other disk types have supported this for
longer) a SIZECHANGE notification is sent to userland via devd.
Add a "nostart" rc.d script (runnable manually but not automatically at
boot time) and a devd script which invokes it when a notification
arrives. The rc.d script enlarges the "final partition" on partitioned
geoms, or the UFS filesystem or zpool device when triggered on a disk
containing either of those.

Commit 7144a1d58c added the hooks for the nfsrdma.ko module.
Once loaded, this module adds RDMA support to the nfsd.
This patch adds a few lines to /etc/rc.d/nfsd, so that
nfs_server_rdma_enable="YES"
in your /etc/rc.conf will load nfsrdma.ko, so that RDMA
service is enabled.
It also supports
nfs_server_rdma_listen="port#"
so that the default of 20490 can be overridden in /etc/rc.conf.
At this available as time, the nfsrdma.ko module is an unofficial port,
since it was developed by Vinicius Ferrao <[email protected]>
using generative AI.
As soon as it is available, it will be announced on
[email protected].
