aee35ecd72 Protect against DoS attacks, such as being described in CVE-2010-2632.
The changes were derived from what has been committed to NetBSD, with
modifications. These are:
1.  Preserve the existsing GLOB_LIMIT behaviour by including the number
    of matches to the set of parameters to limit.
2.  Change some of the limits to avoid impacting normal use cases:
    GLOB_LIMIT_STRING - change from 65536 to ARG_MAX so that glob(3)
	can still provide a full command line of expanded names.
    GLOB_LIMIT_STAT - change from 128 to 1024 for no other reason than
	that 128 feels too low (it's not a limit that impacts the
	behaviour of the test program listed in CVE-2010-2632).
    GLOB_LIMIT_PATH - change from 1024 to 65536 so that glob(3) can
	still provide a fill command line of expanded names.
3.  Protect against buffer overruns when we hit the GLOB_LIMIT_STAT or
    GLOB_LIMIT_READDIR limits. We append SEP and EOS to pathend in
    those cases. Return GLOB_ABORTED instead of GLOB_NOSPACE when we
    would otherwise overrun the buffer.

This change also modifies the existing behaviour of glob(3) in case
GLOB_LIMIT is specifies by limiting the *new* matches and not all
matches. This is an important distinction when GLOB_APPEND is set or
when the caller uses a non-zero gl_offs. Previously pre-existing
matches or the value of gl_offs would be counted in the number of
matches even though the man page states that glob(3) would return
GLOB_NOSPACE when gl_matchc or more matches were found.

The limits that cannot be circumvented are GLOB_LIMIT_STRING and
GLOB_LIMIT_PATH all others can be crossed by simply calling glob(3)
again and with GLOB_APPEND set.

The entire description above applies only when GLOB_LIMIT has been
specified of course. No limits apply when this flag isn't set!

e0cbca43aa In globextend(), take advantage of the fact that realloc(NULL, size) is
equivalent to malloc(size). This eliminates the conditional expression
used for calling either realloc() or malloc() when realloc() will do
all the time.

5192abbac6 In globextend() when the pathv vector cannot be (re-)allocated, don't
free and clear the gl_pathv pointer in the glob_t structure. Such
breaks the invariant of the glob_t structure, as stated in the comment
right in front of the globextend() function. If gl_pathv was non-NULL,
then gl_pathc was > 0. Making gl_pathv a NULL pointer without also
setting gl_pathc to 0 is wrong.

Since we otherwise don't free the memory associated with a glob_t in
error cases, it's unlikely that this change will cause a memory leak
that wasn't already there to begin with. Callers of glob(3) must
call globfree(3) irrespective of whether glob(3) returned an error
or not.

04619555a4 libc: Allow setting close-on-exec in fopen/freopen/fdopen.
This commit adds a new mode option 'e' that must follow any 'b', '+' and/or
'x' options. C11 is clear about the 'x' needing to follow 'b' and/or '+' and
that is what we implement; therefore, require a strict position for 'e' as
well.

For freopen() with a non-NULL path argument and fopen(), the close-on-exec
flag is set iff the 'e' mode option is specified. For freopen() with a NULL
path argument and fdopen(), the close-on-exec flag is turned on if the 'e'
mode option is specified and remains unchanged otherwise.

Although the same behaviour for fopen() can be obtained by open(O_CLOEXEC)
and fdopen(), this needlessly complicates the calling code.

Apart from the ordering requirement, the new option matches glibc.

99d6a5644c Implement DTrace for PowerPC. This includes both 32-bit and 64-bit.
There is one known issue:  Some probes will display an error message along the
lines of:  "Invalid address (0)"

I tested this with both a simple dtrace probe and dtruss on a few different
binaries on 32-bit.  I only compiled 64-bit, did not run it, but I don't expect
problems without the modules loaded.  Volunteers are welcome.
