0afc94c17a mdoc: move CAVEATS, BUGS and SECURITY CONSIDERATIONS sections to the
bottom of the manpages and order them consistently.

GNU groff doesn't care about the ordering, and doesn't even mention
CAVEATS and SECURITY CONSIDERATIONS as common sections and where to put
them.

5b3fab81ab Fix a bug due to a type conversion from 64 to 32 bits. The side effect of
this type conversion is the high bits which were used to indicate if a
special character was a literal or special were dropped. As a result, all
special character were treated as special, even if they were supposed to
be literals.

3d74e220a5 strptime(3) confused July with June with the fr_FR locale.
When parsing the month "juillet" (abbr "jul"), %B recognized it as
"juin" (abbr "jui") because the full name of the month names is
checked at the same time as the abbrevation.

The new behaviour checks the full names first before checking the
abbrevation names.

e27ed89aef Merger of the quota64 project into head.
This joint work of Dag-Erling Smørgrav and myself updates the
FFS quota system to support both traditional 32-bit and new 64-bit
quotas (for those of you who want to put 2+Tb quotas on your users).

By default quotas are not compiled into the kernel. To include them
in your kernel configuration you need to specify:

options         QUOTA                   # Enable FFS quotas

If you are already running with the current 32-bit quotas, they
should continue to work just as they have in the past. If you
wish to convert to using 64-bit quotas, use `quotacheck -c 64';
if you wish to revert from 64-bit quotas back to 32-bit quotas,
use `quotacheck -c 32'.

There is a new library of functions to simplify the use of the
quota system, do `man quotafile' for details. If your application
is currently using the quotactl(2), it is highly recommended that
you convert your application to use the quotafile interface.
Note that existing binaries will continue to work.

Special thanks to John Kozubik of rsync.net for getting me
interested in pursuing 64-bit quota support and for funding
part of my development time on this project.

702f62fb48 getcwd(3): Clarify that EACCES may or may not be checked.
POSIX permits but does not require checking access on the current and parent
directories.

Because various programs do not like it if getcwd(3) fails, it seems best
to avoid checking access as much as possible. There are various reports in
GNATS about this (search for getcwd).

Our getcwd(3) implementation first queries the kernel for the pathname
directly, which does not check any permissions but sometimes fails, and then
falls back to reading all parent directories for the names.

rounding (impl. dep. ), the SPARC JPS1 responsible for SPARC64 and
UltraSPARC processors defines that in all cases  tininess is detected
before rounding therefore rounding up to the smallest normalized number
should set the underflow flag. This change is needed for using SoftFloat
on sparc64 for reference purposes.

f3c733e82b libc/db/hash: cap auto-tuned block size with a value that actually works
This fix mostly matters after r206129 that made it possible for
st_blksize to be greater than 4K.  For this reason, this change should
be MFC-ed before r206129.
Also, it seems that all FreeBSD uitlities that use db(3) hash databases
and create new databases in files, specify their own block size value
and thus do not depend on block size autotuning.

510ea843ba Rename st_*timespec fields to st_*tim for POSIX 2008 compliance.
A nice thing about POSIX 2008 is that it finally standardizes a way to
obtain file access/modification/change times in sub-second precision,
namely using struct timespec, which we already have for a very long
time. Unfortunately POSIX uses different names.

This commit adds compatibility macros, so existing code should still
build properly. Also change all source code in the kernel to work
without any of the compatibility macros. This makes it all a less
ambiguous.

I am also renaming st_birthtime to st_birthtim, even though it was a
local extension anyway. It seems Cygwin also has a st_birthtim.

dabae22639 Two optimizations to MI strlen(3) inspired by David S. Miller's
blog posting [1].

 - Use word-sized test for unaligned pointer before working
   the hard way.

   Memory page boundary is always integral multiple of a word
   alignment boundary.  Therefore, if we can access memory
   referenced by pointer p, then (p & ~word mask) must be also
   accessible.

 - Better utilization of multi-issue processor's ability of
   concurrency.

   The previous implementation utilized a formular that must be
   executed sequentially.  However, the ~, & and - operations can
   actually be caculated at the same time when the operand were
   different and unrelated.

   The original Hacker's Delight formular also offered consistent
   performance regardless whether the input would contain
   characters with their highest-bit set, as it catches real
   nul characters only.

These two optimizations has shown further improvements over the
previous implementation on microbenchmarks on i386 and amd64 CPU
including Pentium 4, Core Duo 2 and i7.

ff2f66ea79 - The OPSZ macro actually only does the right thing for int32 and int64
operands but not for double and extended double ones. Instead of trying
  to fix the macro just nuke it and unroll the loops in the correct way
  though as extended double operands turn out to be the only special case.
- For FxTO{s,d,q} the source operand is int64 so rs2 has to be re-decoded
  after setting type accordingly as it's generally decoded using the low
  2 bits as the type, which are 0 for these three instructions.
- Similarly, in case of F{s,d,q}TOx the target is int64 so rd has to be
  re-decoded using not only the operand mask appropriate for int64 but
  also the correct register number encoding.
- Use const where appropriate.
- Wrap long lines.

interfaces. Do not block rt signals during and after pause(3) calls.
Use private libc namespace to call proper methods.

62399df2c9 Add proper const keywords to sysctl(3) parameters.
The `name' and `newp' arguments can be marked const, because the buffers
they refer to are never changed. While there, perform some other
cleanups:

- Remove K&R from sysctl.c.
- Implement sysctlbyname() using sysctlnametomib() to prevent
  duplication of an undocumented kernel interface.
- Fix some whitespace nits.

It seems the prototypes are now in sync with NetBSD as well.

066d438476 Unbreak ia64: tls_model("initial-exec") is invalid, because it assumes

TLS model. The consequence was data corruption. Limit the attribute to

Empty string test gone wrong.

Testing this requires that you have a locale that has the sign string
unset but has int_n_sign_posn set (the default locale falls through to
use "()" around negative numbers which is probably another bug).

I created that setup by hand and indeed without this fix negative
numbers are put out as positive numbers (doesn't fall through to use
"-" as default indicator).

Unfixed example in nl_NL.ISO8859-1 with lc->negative_sign set to empty
string:
  strfmon(buf, sizeof(buf), "%-8i", -42.0);
==>
example2: 'EUR  42,00' 'Eu 42,00'

Fixed:
example2: 'EUR  42,00-' 'Eu 42,00-'

This file and suggested fix are identical in at least freebsd-8.
Backport might be appropriate but some expert on locales should
probably have a look at us defaulting to negative numbers in
parenthesis when LC_* is default.  That doesn't look right and is not
what other OSes are doing.

90b4621a5f Add PT_VM_TIMESTAMP and PT_VM_ENTRY so that the tracing process can
obtain the memory map of the traced process. PT_VM_TIMESTAMP can be
used to check if the memory map changed since the last time to avoid
iterating over all the VM entries unnecesarily.

2f9f616df9 Reinstate the ptrace patch to restore the 'gp' register after calling
a function. I made a mistake in assuming that the .cprestore directive
will cause the assembler to automatically restore 'gp' after the 'jalr'.

The .cprestore directive does its magic only after 'jal' and 'bal'
instructions - not the 'jalr'.
