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.

e113edf30a o Move a lot of parameter checking from netisr_poll() to
dedicated sysctl handlers. Protect manipulations with
  poll_mtx. The affected sysctls are:
  - kern.polling.burst_max
  - kern.polling.each_burst
  - kern.polling.user_frac
  - kern.polling.reg_frac
o Use CTLFLAG_RD on MIBs that supposed to be read-only.
o u_int32t -> uint32_t

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.

2bc6081c9f Reintroduce the lmc T1/E1/T3 WAN driver. This version is locked, supports
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.

fec39060e2 Fixing WEP bustage in hostap mode since 5.2-RELEASE.
- WEP TX fix:

  The original code called software crypto, ieee80211_crypto_encap(),
which never worked since IEEE80211_KEY_SWCRYPT was never flagged due to
ieee80211_crypto_newkey() assumes that wi always supports hardware based
crypto regardless of operational mode(by virtue of IEEE80211_C_WEP).
This fix works around that issue by adding wi_key_alloc() to force
the use of s/w crypto.  Also if anyone ever decides to cleanup ioctl
handling where key changes wouldn't cause a call to wi_init() every time,
we'll need wi_key_alloc() to DTRT.

  In addition to that, this fix also adds code to wi_write_wep() to force
existing keys to be switched between h/w and s/w crypto such that an
operation mode change(sta <-> hostap) will flag IEEE80211_KEY_SWCRYPT
properly.

- WEP RX fix:

  Clear IEEE80211_F_DROPUNENC even in hostap mode.  Quote from Sam:

	"This is really gross but I don't see an easy way around it.
	By doing it we lose the ability to independently drop unencode
	frames (and support mixed wep/!wep use).  We should really be
	setting the EXCLUDE_UNENCRYPTED flag written in wi_write_wep
	based on IEEE80211_F_DROPUNENC but with our clearing it we can't
	depend on it being set properly."
