9e49a2370c Add function pthread_timedjoin_np, the function is similar with pthread_join
except the function will return ETIMEDOUT if target thread does not exit
before specified absolute time passes.

67a7895ff4 For some utterly bizarre reason, sparc64 coerces PAGE_SIZE to be a long
instead of an int.  No other FreeBSD architecture does this.  Patch over
this problem in the lmc driver.  While I'm here, correct a mistake with
DEVICE_POLLING.

448434c3c9 Initialize the inode i_flag field in ffs_valloc() to clean up any
stale flag bits left over from before the inode was recycled.

Without this change, a leftover IN_SPACECOUNTED flag could prevent
softdep_freefile() and softdep_releasefile() from incrementing
fs_pendinginodes.  Because handle_workitem_freefile() unconditionally
decrements fs_pendinginodes, a negative value could be reported at
file system unmount time with a message like:
        unmount pending error: blocks 0 files -3
The pending block count in fs_pendingblocks could also be negative
for similar reasons.  These errors can cause the data returned by
statfs() to be slightly incorrect.  Some other cleanup code in
softdep_releasefile() could also be incorrectly bypassed.

721d95b6b2 Use more rc.subr bits to clean up pccard_ether and implement new
features.  Both the presence of a NOAUTO keyword and an interface being
up can be ignored is the forcestart option is used.  Additionally, a
restart option has been added.

Colin Percival
33812c066d If sufficiently bad things happen during a call to kern_execve(), it is
possible for do_execve() to call exit1() rather than returning.  As a
result, the sequence "allocate memory; call kern_execve; free memory"
can end up leaking memory.

This commit documents this astonishing behaviour and adds a call to
exec_free_args() before the exit1() call in do_execve().  Since all
the users of kern_execve() in the tree use exec_free_args() to free
the command-line arguments after kern_execve() returns, this should
be safe, and it fixes the memory leak which can otherwise occur.

1fa9efeffb Acquire Giant conditionally in in_addmulti() and in_delmulti() based on
whether the interface being accessed is IFF_NEEDSGIANT or not.  This
avoids lock order reversals when calling into the interface ioctl
handler, which could potentially lead to deadlock.

The long term solution is to eliminate non-MPSAFE network drivers.

interface polling, compiles on 64-bit platforms, and compiles on NetBSD,
OpenBSD, BSD/OS, and Linux.  Woo!  Thanks to David Boggs for providing this
driver.

Altq, sppp, netgraph, and bpf are required for this driver to operate.
Userland tools and man pages will be committed next.

5032ff8197 Always wire the sysctl output buffer in sysctl_kern_proc() before
calling sysctl_out_proc().  -- fix from jhb

Move the code in fill_kinfo_thread() that gathers data from struct proc
into the new function fill_kinfo_proc_only().

Change all callers of fill_kinfo_thread() to call both
fill_kinfo_proc_only() and fill_kinfo() thread.  When gathering
data from a multi-threaded process, fill_kinfo_proc_only() only needs
to be called once.

Grab sched_lock before accessing the process thread list or calling
fill_kinfo_thread().

da927f93bd - Call db_setup_paging() for traceall.
- Make it so one can't call db_setup_paging() if it has already been called
before. traceall needs this, or else the db_setup_paging() call from
db_trace_thread() will reset the printed line number, and override its
argument.
This is not perfect for traceall, because even if one presses 'q' while in
the middle of printing a backtrace it will finish printing the backtrace
before exiting, as db_trace_thread() won't be notified it should stop, but
it is hard to do better without reworking the pager interface a lot more.
