(Previously they were equal, but under a close reading of POSIX, NGROUPS_MAX was defined to be too large by 1 since it is the number of supplemental groups, not total number of groups.) The bulk of the change consists of converting the struct ucred member cr_groups from a static array to a pointer. Do the equivalent in kinfo_proc. Introduce new interfaces crcopysafe() and crsetgroups() for duplicating a process credential before modifying it and for setting group lists respectively. Both interfaces take care for the details of allocating groups array. crsetgroups() takes care of truncating the group list to the current maximum (NGROUPS) if necessary. In the future, crsetgroups() may be responsible for insuring invariants such as sorting the supplemental groups to allow groupmember() to be implemented as a binary search. Because we can not change struct xucred without breaking application ABIs, we leave it alone and introduce a new XU_NGROUPS value which is always 16 and is to be used or NGRPS as appropriate for things such as NFS which need to use no more than 16 groups. When feasible, truncate the group list rather than generating an error. Minor changes: - Reduce the number of hand rolled versions of groupmember(). - Do not assign to both cr_gid and cr_groups[0]. - Modify ipfw to cache ucreds instead of part of their contents since they are immutable once referenced by more than one entity.

Jails may have their own host information, or they may inherit it from the parent/system. The proper way to read the hostname is via getcredhostname(), which will copy either the hostname associated with the passed cred, or the system hostname if you pass NULL. The system hostname can still be accessed directly (and without locking) at prison0.pr_host, but that should be avoided where possible. The "similar information" referred to is domainname, hostid, and hostuuid, which have also become prison parameters and had their associated global variables removed.

Being exported, AT_CLKTCK is returned by sysconf(_SC_CLK_TCK), glibc falls back to the hard-coded CLK_TCK value when aux entry is not present. Glibc versions prior to 2.2.1 always use hard-coded CLK_TCK value. For older applications/libc's which depends on hard-coded CLK_TCK value user should set compat.linux.osrelease less than 2.4.0.

If AT_CLKTCK entry is not exported, Glibc uses 100. linux_times() shall use the value that is exported to user space.
