3962505497 This little BSD licensed library has been kicking around for years.
It allows one to trivially convert an absolute path to a relative path
and the reverse. The test programs themselves are very useful in scripts
but the real use comes shortly with the -r and -a arguments to ln.
These are sometimes known as the --relative and --absolute flags and
can force a symlink to be relative when you only have an absolue path.
Another place these are sometimes used is to add -a and -r args to 'realpath'.
Incredibly useful in Makefiles.

I was going to just add the files in with 'ln' but a library makes more sense.
The test programs may come out in their own right some day for scripting.

released under a BSD 2-clause:

The test directry does not conform to any framework.

56c196dc25 open(2): Clarify non-POSIX error when opening a symlink with O_NOFOLLOW.
We return [EMLINK] instead of [ELOOP] when trying to open a symlink with
O_NOFOLLOW, so that the original case of [ELOOP] can be distinguished. Code
like cmp -h and xz takes advantage of this.

a20c52a118 Fix error reporting from wcstof()
When wcstof() skipped initial space and then parsing failed, it set
endptr to the first non-space character.  Fix it to correctly report
failure by setting endptr to the beginning of the input string.
The fix is from theraven@, who fixed this bug in wcstod() and
wcstold() in r227753.

While I'm here:

Move assignments out of declarations in wcstod() and wcstold().
This is against my personal preference, but it is our agreed style(9).

Set endptr correctly on malloc() failure in all three functions.

Remove an incorrect comment:  This is pointer arithmetic,
so the code was not actually making that assumption.

wcstold() advanced the wcp pointer beyond leading whitespace
and then reset it back to the beginning of the string.
Do not reset it.  This seems to have no functional effect,
since strtold_l() also skips leading whitespace.  I'm making
the change to keep this function consistent with wcstof() and
wcstod(), and because the C11 spec prescribes the use of iswspace()
to skip leading space.

8d17c296fe Fix buildworld for powerpc.
vmpage requires struct pmap to exist and contain a pm_stats field.  As of
r308817, either AIM or BOOKE is required to be set in order to get their
respective pmap structs.  Rather than expose them both, or try to unify them
unnecessarily, add a third option which contains only a pm_stats field, and
change the two existing pmap structures to place the common fields at the
beginning of the struct.  This actually fixes the stats collection by libkvm on
AIM hardware, because before it was accessing a possibly different offset, which
would cause it to read garbage.

Bump __FreeBSD_version to denote this ABI change, so that ports which depend on
libkvm can be rebuilt.

9e66c6e8f0 Speed up pw operations that edit /etc/group or /etc/passwd
r285050 fixed a bug in pw that could lead to /etc/passwd or /etc/group
corruption on power loss. However, it fixed it by opening those files with
O_SYNC, which is very slow, especially on ZFS. This change replaces O_SYNC
with appropriately placed fsync()s instead, which is much faster. Using a
ZFS tmpdir, the time to run pw's kyua tests drops from 245s to 35s.

4455fc87b3 Loader paged/pageable data is not always paged.
This change does modify devsw dv_print() to return the int value,
enabling walkers to interrupt the walk on non zero value from dv_print().

This will allow the pager_print actually to stop displaying data on
user input, and additionally pager is used in various *dev_print callbacks,
where it was missing.

For test, lsdev [-v] command should display data by screenfuls and should
stop when the key 'q' is pressed on pager prompt.

13d9c12d58 Replace basename(3) by a thread-safe implementation.
Now that the changes to the dirname(3) function had some time to settle,
let's go ahead and use the same approach for replacing basename(3) by a
simple implementation that modifies the input string, thereby making it
thread-safe and guaranteed to succeed.

Unlike dirname(3), this function already had a thread-safe variant
basename_r(3). This function had its own set of problems, like having an
upper bound on the pathname length. Keep this function around for
compatibility, but remove most references from the man page. Make the
man page more similar to that of dirname(3).

As the basename_r(3) function is only provided by FreeBSD (and Bionic),
depending on its use is even more implementation defined than assuming
that basename(3) is thread-safe.

40c4c3de40 Create a new MACHINE_ARCH for Freescale PowerPC e500v2
Summary:
The Freescale e500v2 PowerPC core does not use a standard FPU.
Instead, it uses a Signal Processing Engine (SPE)--a DSP-style vector processor
unit, which doubles as a FPU.  The PowerPC SPE ABI is incompatible with the
stock powerpc ABI, so a new MACHINE_ARCH was created to deal with this.
Additionaly, the SPE opcodes overlap with Altivec, so these are mutually
exclusive.  Taking advantage of this fact, a new file, powerpc/booke/spe.c, was
created with the same function set as in powerpc/powerpc/altivec.c, so it
becomes effectively a drop-in replacement.  setjmp/longjmp were modified to save
the upper 32-bits of the now-64-bit GPRs (upper 32-bits are only accessible by
the SPE).

Note: This does _not_ support the SPE in the e500v1, as the e500v1 SPE does not
support double-precision floating point.

Also, without a new MACHINE_ARCH it would be impossible to provide binary
packages which utilize the SPE.

Additionally, no work has been done to support ports, work is needed for this.
This also means no newer gcc can yet be used.  However, gcc's powerpc support
has been refactored which would make adding a powerpcspe-freebsd target very
easy.

Test Plan:
This was lightly tested on a RouterBoard RB800 and an AmigaOne A1222
(P1022-based) board, compiled against the new ABI.  Base system utilities
(/bin/sh, /bin/ls, etc) still function appropriately, the system is able to boot
multiuser.
