to repeatedly read the conf files. Depending on what is enabled the
files are being read anywhere from 15, 30, or more times currently.
By loading the values in the environment this is reduced to 1, with
perhaps a couple more, again depending on what is enabled.
The speed-up for boot and shutdown is negligible when rc.conf is
on local disk, noticable when accessing files over NFS, and dramatic
when pulling rc.conf values from a database.
This change also includes a minor optimization to the conditional
for $_rc_conf_loaded.

Implement the long double version for the cube root function, cbrtl.
The algorithm uses Newton's iterations with a crude estimate of the
cube root to converge to a result.

the inp->in6p_laddr (laddr) and a following priv_check_cred() call
would return an error and will allow us to merge the IPv4 and IPv6

behavior, where the module checks that the supplicant is a member of the
required group. The latter checks the target user instead. If neither
option was specified, pam_group(8) assumes "ruser" and issues a warning.
I intend to eventually change the default to "luser" to match the
behavior of similarly-named service modules in other operating systems.

even after dropping the reference and unlocking. Previously we
have dereferenced a NULL pointer (after r121765).
Simply unlocking after the block does not work either because of
lock ordering (see r121765) and in addition we would still hold
a pointer to something that might be gone by the time we access it.
Thus take a copy of the value rather than just caching the pointer.

Add systrace_linux32 and systrace_freebsd32 modules which provide
support for tracing compat system calls in addition to native system
call tracing provided by systrace module.
Provided that all the systrace modules are loaded now you can select
what syscalls to trace in the following manner:
syscall::xxx:yyy - work on all system calls that match the specification
syscall:freebsd:xxx:yyy - only native system calls
syscall:linux32:xxx:yyy - linux32 compat system calls
syscall:freebsd32:xxx:yyy - freebsd32 compat system calls on amd64

turned out to yield slightly better buildstone performance.
- Emitt an error when encountering an unsupported and in case of the

- Fix R_SPARC_LOX10 relocations. Apparently these are hardly ever used.
- Add the _RF_X committed in r212998 also to the tables in the sparc64
reloc.c in order reduce differences between the kernel and the userland
source. This results in no functional change though.
- Fix further inconsistencies in the abbreviations of the names of the

* elf64-sparc.c (sparc64_elf_relocate_section): Adjust addend of
dynamic relocs against section symbols for the output section vma.
However, with the addition of TLS support in the upstream rev. 1.104
this fix was essentially reverted. After factoring out the common parts
of elf32-sparc.c and elf64-sparc.c a comment was added to elfxx-sparc.c
in the upstream rev. 1.27 as part of unrelated changes, saying that the
fix from elf64-sparc.c rev. 1.61 indeed should be implemented, but given
that some unspecified OS has a broken ld.so expecting broken relocations
deliberately is omitted.
As the current behavior actually violates the SPARC ABI, FreeBSD never
had such a broken ld.so and this is actually causing problems with at
least kernel modules linked with binutils 2.17.50 committed in r218822
without the workaround committed in r219340 in place, re-implement the
above fix in a way so that is only applied if the output format is
ELFOSABI_FREEBSD. In the upstream version it probably would make sense
to invert this check and only skip adjusting the addend for the OS with
the broken ld.so, once it's determine which one that is.
