b812fe4d6b [mips] add support for using the MIPS user register for TLS data.
This work, originally from Stacey Son, uses the MIPS UserReg for
reading the TLS data, and will fall back to the normal syscall path
when it isn't supported.

This code dynamically patches cpu_switch() to bypass the UserReg
instruction so to avoid generating a machine exception.

Thanks to sson for the original work, and to Dan Nelson for
bringing it to date and testing it on MIPS32 with me.

Tested:

* mips64 (sson)
* mips74k (dnelson_1901@yahoo.com) - AR9344 SoC, UserReg support
* mips24k (adrian) - AR9331 SoC, no UserReg support

1c1093d6d6 Fix dlsym(RTLD_NEXT) handling to only return the next library in last library cases.
The root of the problem here is that TAILQ_FOREACH_FROM will default to
the head of the list if passed NULL, which will be the case if there are
no libraries loaded after this one.  Thus all libraries, including the
current, were iterated in that case rather than none.

This was broken in r294373.

e7debdcb15 Fix race for incrementally rebuilding VERSION_MAP.
The dependency is needed in PROG_FULL since only the build of PROG_FULL
is using the LDFLAGS and depending on VERSION_MAP.  This was not a problem
with MK_DEBUG_FILES==no since it only builds PROG.

This should probably be using bsd.lib.mk instead [1]

504422fab3 Update blacklist support in ftpd to clarify fd usage
The ftp daemon dups the control socket to stdin and uses that fd
throughout the code.  Clarify this usage slightly by changing from
explicit use of "0" for the fd to a variable, to make it clear what
the zero represents in the non-blacklist code. Make the
blacklist_notify routine use STDIN_FILENO so as to have less of a
"magic number" feel to the code.

The 'CONFS' entries in share/mk/bsd.confs.mk explicitly check
for the 'installconfig', but does not behave properly with the

This seems to be related to the previously-reported issues
with files within /etc in the past.

360ba6bc13 Fix issues found by Coverity in the rtld-elf.c:gethints().
Check that the dirlist path string specification does not cause
overflow and is fully contained in the hints file.
Check that the dirlist string is nul-terminated.
Make 'hdr' static variable, so that hdr.dirlistlen is available when
hints cached value is used on next function calls.  Reset hdr.dirlistlen
to zero if error was detected, so that allocations use reasonable size.
Use 'hints', and not 'p' in the body, since p is only initialized on the
first call.

430f7286a5 Merge ^/user/ngie/release-pkg-fix-tests to unbreak how test files are installed
after r298107

Summary of changes:

- Replace all instances of FILES/TESTS with ${PACKAGE}FILES. This ensures that
  namespacing is kept with FILES appropriately, and that this shouldn't need
  to be repeated if the namespace changes -- only the definition of PACKAGE
  needs to be changed
- Allow PACKAGE to be overridden by callers instead of forcing it to always be
  `tests`. In the event we get to the point where things can be split up
  enough in the base system, it would make more sense to group the tests
  with the blocks they're a part of, e.g. byacc with byacc-tests, etc
- Remove PACKAGE definitions where possible, i.e. where FILES wasn't used
  previously.
- Remove unnecessary TESTSPACKAGE definitions; this has been elided into
  bsd.tests.mk
- Remove unnecessary BINDIRs used previously with ${PACKAGE}FILES;
  ${PACKAGE}FILESDIR is now automatically defined in bsd.test.mk.
- Fix installation of files under data/ subdirectories in lib/libc/tests/hash
  and lib/libc/tests/net/getaddrinfo
- Remove unnecessary .include <bsd.own.mk>s (some opportunistic cleanup)

Document the proposed changes in share/examples/tests/tests/... via examples
so it's clear that ${PACKAGES}FILES is the suggested way forward in terms of
replacing FILES. share/mk/bsd.README didn't seem like the appropriate method
of communicating that info.

ca8c8dc3eb Fix handling of DT_TEXTREL for an object with more than one read-only
segment.  According to gABI spec, presence of the tag indicates that
dynamic linker must be prepared to handle relocations against any
read-only segment, not only the segment which we, somewhat arbitrary,
declared the text.

For each read-only segment, add write permission before relocs are
processed, and return to the mapping mode requested by the phdr, after
relocs are done.

c501d73c7e Convert casperd(8) daemon to the libcasper.
After calling the cap_init(3) function Casper will fork from it's original
process, using pdfork(2). Forking from a process has a lot of advantages:
1. We have the same cwd as the original process.
2. The same uid, gid and groups.
3. The same MAC labels.
4. The same descriptor table.
5. The same routing table.
6. The same umask.
7. The same cpuset(1).
From now services are also in form of libraries.
We also removed libcapsicum at all and converts existing program using Casper
to new architecture.
