a257862d4b When (re)allocating space for an array of pointers to char, use
sizeof(*list), not sizeof(**list).  (i.e., sizeof(pointer) rather than
sizeof(char)).

It is possible that this buffer overflow is exploitable, but it was
added after RELENG_5 forked and hasn't been MFCed, so this will not
receive an advisory.

c479a90eb8 Add GIANT_REQUIRED and WITNESS sleep warnings to uprintf() and tprintf(),
as they both interact with the tty code (!MPSAFE) and may sleep if the
tty buffer is full (per comment).

Modify all consumers of uprintf() and tprintf() to hold Giant around
calls into these functions.  In most cases, this means adding an
acquisition of Giant immediately around the function.  In some cases
(nfs_timer()), it means acquiring Giant higher up in the callout.

With these changes, UFS no longer panics on SMP when either blocks are
exhausted or inodes are exhausted under load due to races in the tty
code when running without Giant.

NB: Some reduction in calls to uprintf() in the svr4 code is probably
desirable.

NB: In the case of nfs_timer(), calling uprintf() while holding a mutex,
or even in a callout at all, is a bad idea, and will generate warnings
and potential upset.  This needs to be fixed, but was a problem before
this change.

NB: uprintf()/tprintf() sleeping is generally a bad ideas, as is having
non-MPSAFE tty code.

583b25a64f Remove mac_create_root_mount() and mpo_create_root_mount(), which
provided access to the root file system before the start of the
init process.  This was used briefly by SEBSD before it knew about
preloading data in the loader, and using that method to gain
access to data earlier results in fewer inconsistencies in the
approach.  Policy modules still have access to the root file system
creation event through the mac_create_mount() entry point.

Removed now, and will be removed from RELENG_6, in order to gain
third party policy dependencies on the entry point for the lifetime
of the 6.x branch.

41d865435a Fixed aliasing bugs in TRUNC() by using the fdlibm macros for access
to doubles as bits.  fdlibm-1.1 had similar aliasing bugs, but these
were fixed by NetBSD or Cygnus before a modified version of fdlibm was
imported in 1994.  TRUNC() is only used by tgamma() and some
implementation-detail functions.  The aliasing bugs were detected by
compiling with gcc -O2 but don't seem to have broken tgamma() on i386's
or amd64's.  They broke my modified version of tgamma().

Moved the definition of TRUNC() to mathimpl.h so that it can be fixed
in one place, although the general version is even slower than necessary
because it has to operate on pointers to volatiles to handle its arg
sometimes being volatile.  Inefficiency of the fdlibm macros slows
down libm generally, and tgamma() is a relatively unimportant part of
libm.  The macros act as if on 32-bit words in memory, so they are
hard to optimize to direct actions on 64-bit double registers for
(non-i386) machines where this is possible.  The optimization is too
hard for gcc on amd64's, and declaring variables as volatile makes it
impossible.

5376d97a97 Fix configuration locking in MD.
Remove  md_mtx.

Remove GIANT from the mdctl device driver and avoid DROP_GIANT,
PICKUP_GIANT and geom events since we can call into GEOM directly
now.

Pick up Giant around vn_close().

Apply an exclusive sx around mdctls ioctl and preloading to protect
lists etc..

Don't initialize our lock (md_mtx or md_sx) from a
SYSINIT when there is a perfectly good pair of _fini/_init
functions to do it from.

Prune any final fractional sector from the mediasize to
keep GEOM happy.

Cleanups:

Unify MDIOVERSION check in (x)mdctlioctl()

Add pointer to start() routine to softc to eliminate a switch{}

Inline guts of mddetach().

Always pass error pointer to mdnew(), simplify implementation.

cause a crash.  Eliminate this possibility by moving the if_free to

37a0bbb7e5 Add the beginnings of a testsuite for testing GPT control requests.
The testsuite is based on a simple driver program that builds a
request from the arguments passed to it and issues the request to
Geom. The driver emits FAIL with the error string or PASS depending
on whether the request completed with an error or not. A -v option
has been added to the driver and causes the request to be dumped.
The -v option to prove(1) controls the -v option to the driver.

The testsuite itself contains a hash of which the key constitutes
the arguments and the value is the expected result.

0fa86d9cb5 MFp4:
o eliminate the ED_NO_MIIBUS option.  Now, you need miibus to use ed with
  pccard.  If you have an old ISA or PCI card w/o a miibus, then you'll still
  be able to use the ed driver w/o miibus in the kernel.  If you have pccard
  you'll need mii now.  Most pccards these days have miibus, and many
  cards have ISSUES if you don't attach miibus.  issues I don't want to
  constantly rediagnose.
  - Add new media_ioctl, mediachg and tick function pointers.  The core
    driver will call these if they aren't NULL, or return an error if they
    are.
  - migrate remaining mii code into if_ed_pccard.
o include some notes from my datasheet fishing.  this may allow us to
  get media status from some pccards.
o Fix one bug that's common to many drivers.  call if_free(ifp) after
  we tear down the interrupt.  ed_intr() depends on ifp being there and
  freeing it while interrupts can still happen is, ummm, bad.

64eedb0310 Take a first cut at cleaning up ifnet removal and multicast socket
panics, which occur when stale ifnet pointers are left in struct
moptions hung off of inpcbs:

- Add in_ifdetach(), which matches in6_ifdetach(), and allows the
  protocol to perform early tear-down on the interface early in
  if_detach().

- Annotate that if_detach() needs careful consideration.

- Remove calls to in_pcbpurgeif0() in the handling of SIOCDIFADDR --
  this is not the place to detect interface removal!  This also
  removes what is basically a nasty (and now unnecessary) hack.

- Invoke in_pcbpurgeif0() from in_ifdetach(), in both raw and UDP
  IPv4 sockets.

It is now possible to run the msocket_ifnet_remove regression test
using HEAD without panicking.

af8c8375af - In gem_ioctl() move the call to ether_ioctl() to the default case of
the switch statement in order to make this driver more like other
  Ethernet NIC drivers.
- In gem_attach() call gem_stop() in addition to gem_reset() to make
  sure the chip actually is stopped and not just reset.
- In gem_stop() also stop the gem_rint_timeout() callout in case the
  driver is compiled with GEM_RINT_TIMEOUT defined.

Merge some locking improvements from hme(4):
- Use callout_init_mtx() to close races between gem_stop() and gem_tick()
  as weel as gem_stop() and gem_rint() in case the driver is compiled
  with GEM_RINT_TIMEOUT defined.
- Use the driver lock instead of Giant in a bus dma callback.
- Lock the driver lock around mii operations.
- Cleanup locking in gem_ioctl().
- Remove redundant assertions that the driver lock is not held in
  gem_attach() and gem_detach() since mtx_lock() will assert that
  already since the driver lock is not recursive.
- Add callout_drain()'s to gem_detach() after calling gem_stop() to make
  sure that if softclock is running on another CPU and is blocked on our
  driver lock, we will wait until it has acquired the lock, seen that it
  was cancelled, dropped the lock, and awakened us so that we can safely
  destroy the mutex.
