cmcred_groups[0] in 'struct cmsgcred' must be the effective GID. Note that the code in unp_addsockcred() filling up 'struct sockcred'/'struct sockcred2' (LOCAL_CREDS/LOCAL_CREDS_PERSISTENT options) was in fact "wrong" before 'cr_gid' was moved out of cr_groups[], in the sense that it would transmit the effective GID twice, both separately as 'sc_egid' and as the first element of 'sc_groups'. It is now exact, so is left unchanged, which causes a difference in output (the effective GID is no more in 'sc_groups', unless it is also a supplementary group) that is unlikely to affect applications in practice.

This is the top level of the FreeBSD source directory.
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
