(__HAVE_PTRACE_MACHDEP) and procfs (__HAVE_PROCFS_MACHDEP).
These changes will allow platforms like x86 (XMM) and PowerPC
(AltiVec) to export extended register sets in a sane manner.
* Use __HAVE_PTRACE_MACHDEP to export x86 XMM registers (standard
FP + SSE/SSE2) using PT_{GET,SET}XMMREGS (in the machdep
ptrace request space).
* Use __HAVE_PROCFS_MACHDEP to export x86 XMM registers via
/proc/N/xmmregs in procfs.
case when the requested memory size can't ever be granted - instead
of panic, malloc(9) would return failure (NULL).
Note kernel code should do proper bound checking, rather than
depend on M_CANFAIL. This flag is only supposed to be used in very
special cases, where common bound checking is not appropriate.
Discussed on tech-kern@, name ``M_CANFAIL'' suggested by Chuck Cranor.
- use cpp -traditional, since the default has now changed. We want to allow
unmatched single quotes!
- use fparseln, instead of a fixed 2k buffer.
- make all locals static and move to the top. This is so we can eventually
make calendar understand languages other than us_en
- add braces and continue's to clarify things.
- replace gratuitous fprintf uses with warnx.
- replace vforks() with forks() since we tried to print errors with stdio.
- add more warnings so that we know how things fail.
XXX: Eventually we'll have to remove the cpp dependency, and we should:
- make it use m4 instead [bad, breaks compatibility]
or
- add a small cpp like parser for #include [bad, too much code]
- 'denyquick'; deny a connection so tagged by ftpusers(5) after the USER
command instead of the PASS command. whilst this might provide some
info leakage of accounts names if you have some `real' or `chroot'
users enabled and not others, it does prevent accidental entering of
such passwords if you have all such users denied. This option is
strongly recommended on anonymous-only servers.
Functionality requested by Rob Windsor in [bin/12602]
- 'private'; don't display class related information in the output of STAT.
