fae7e96d82 Add a test to verify compatibility with archives with
odd hardlinks.  I need to extend this to test pax extended
archives with bodies attached to hardlinks and other less-common cases.

6f6dfc16c2 Tighten up the heuristic that decides whether or not we should
obey or ignore the size field on a hardlink entry.  In particular,
if we're reading a non-POSIX archive, we should always ignore
the size field.

This should fix both the audio/xmcd port and the math/unixstat port.

Thanks to: Pav Lucistnik for pointing these two ports out to me.

8f2948f1c1 Bring in the nice work from Mark Tinguely on arm pmap.
The only downside is that it renames pmap_vac_me_harder() to pmap_fix_cache().
From Mark's email on -arm :
pmap_get_vac_flags(), pmap_vac_me_harder(), pmap_vac_me_kpmap(), and
pmap_vac_me_user() has been rewritten as pmap_fix_cache() to be more
efficient in the kernel map case. I also removed the reference to
the md.kro_mappings, md.krw_mappings, md.uro_mappings, and md.urw_mappings
counts.

In pmap_clearbit(), we can also skip over tests and writeback/invalidations
in the PVF_MOD and PVF_REF cases if those bits are not set in the pv_flag.
PVF_WRITE will turn caching back on and remove the PV_MOD bit.

In pmap_nuke_pv(), the vm_page_flag_clear(pg, PG_WRITEABLE) has been moved
to the pmap_fix_cache().

We can be more agressive in attempting to turn caching back on by calling
pmap_fix_cache() at times that may be appropriate to turn cache on
(a kernel mapping has been removed, a write has been removed or a read
has been removed and we know the mapping does not have multiple write
mappings to a page).

In pmap_remove_pages() the cpu_idcache_wbinv_all() is moved to happen
before the page tables are NULLed because the caches are virtually
indexed and virtually tagged.

In pmap_remove_all(), the pmap_remove_write(m) is added before the
page tables are NULLed because the caches are virtually indexed and
virtually tagged. This also removes the need for the caches fixing routine
(whichever is being used pmap_vac_me_harder() or pmap_fix_cache()) to be
called on any of these mappings.

In pmap_remove(), I simplified the cache cleaning process and removed
extra TLB removals. Basically if more than PMAP_REMOVE_CLEAN_LIST_SIZE
are removed, then just flush the entire cache.

9cf15e9671 Add unix_sorflush, a regression test for the following scenario:
- Process (a) is blocked in read on a socket waiting on data.
 - Process (b) is blocked in shutdown() on a socket waiting on (a).
 - Process (c) delivers a signal to (b) interrupting its wait.

When the signal is delivered, the kernel panics as sblock() fails in
sorflush().  Even if it didn't panic, shutdown() would block potentially
indefinitely waiting for recv() to succeeded.  Fixes to follow.

2369087a60 - Rework the kld support to hook into GDB's shared library support.
kgdb(8) now treats kld's as shared libraries relative to the kernel
  "binary".  Thus, you can use 'info sharedlibrary' to list the kld's
  along with 'sharedlibrary' and 'nosharedlibrary' to manage symbol
  loading and unloading.  Note that there isn't an easy way to force GDB
  to use a specific path for a shared library.  However, you can use
  'nosharedlibrary' to unload all the klds and then use 'sharedlibrary'
  to load specific klds where it gets the kld correct and use
  'add-kld' for the kld's where the default open behavior doesn't work.
  klds opened via 'sharedlibrary' (and during startup) do have their
  sections listed in 'info files'.
- Change the 'add-kld' command to use filename completion to complete its
  argument.

that we don't list sections for memory in the crash dump.

5ca09def5b Add support for automatically loading symbols for kld's on startup:
- Add a new 'kgdb_auto_load_klds()' routine which is invoked during
  startup that walks the list of linker files and tries to find a matching
  kld on disk for each non-kernel kld.  If a kld file is found, then it
  is added as if the 'add-kld' command is invoked.  One change from
  'add-kld' is that this method attempts to use the 'pathname' from the
  linker_file structure first to try to load the file.  If that fails
  it then looks in the kernel directory followed by the directories in
  the module path.
- Move the kld file suffix handling into a separate routine so that it
  can be called standalone and to reduce duplicate code in find_kld_path().
- Cache the offsets of members of 'struct linker_file' during startup
  instead of computing them for each 'add-kld'.
- Use GDB's target_read_string() instead of direct KVM access.
- Add all resident sections from a kld by using bfd_map_over_sections() to
  build the section list rather than just adding symbols for ".text",
  ".data", ".bss", and ".rodata".
- Change the 'add-kld' command to do a y/n prompt before adding the
  symbols when run interactively to match 'add-symbol-file'.

c52a508838 Make sure that the termid type is initialized to AU_IPv4 by default.
This makes sure that process tokens credentials with un-initialized
audit contexts are handled correctly.  Currently, when invariants are
enabled, this change fixes a panic by ensuring that we have a valid
termid family.  Also, this fixes token generation for process tokens
making sure that userspace is always getting a valid token.

This is consistent with what Solaris does when an audit context is
un-initialized.

relabel check for MLS rather than returning 0 directly.

This problem didn't result in a vulnerability currently as the central
implementation of ifnet relabeling also checks for UNIX privilege, and
we currently don't guarantee containment for the root user in mac_mls,
but we should be using the MLS definition of privilege as well as the
UNIX definition in anticipation of supporting root containment at some
point.
