- Convert all K&R definitions to ANSI equialents.
- Retire bsd_malloc and bsd_free macros and
use malloc/free directly.
- Drop some unused debugging calls.
This commit brings no functional changes.
Minimize differencies between our ext2fs headers and relevant Linux
versions by using EXT2_SB macro to access the superblock fields. Most
of the differencies in access to these fields are now hidden inside
this macro.
- Rename the s_db_per_group field of ext2fs_sb_info to s_gdb_count
to reflect the similar change in Linux headers. New name also seem
to be more appropriate for this field.
- Use proper types for s_first_inode and s_inode_size in-core superblock
fields. Now they reflec types used in the on-disk superblock version.
- Add support for older filesystem revisions that doesn't have proper
s_first_ino and s_inode_size fields in the on-disk superblock. In these
cases predefined values for these fields are used.
- Add simple sanity checks for s_first_inode and s_inode_size correctness.

deleted when the system is low on memory. This ought to allow an increase to
vfs.ufs.dirhash_maxmem on machines that have lots of memory, without
degrading performance by having too much memory reserved for dirhash when
other things need it. The default value for dirhash_maxmem is being kept at
2MB for now, though.
This work was mostly done during the 2008 Google Summer of Code.

makes it easier for first-time users to configure and work with biba as
remote acess is still allowed. Effectively, this means that, by default,
only local security properties, not distributed ones, are enforced.

might arise from WITNESS not understanding its locking protocol, which
should be deadlock-free. Currently these warnings generally don't occur,
but as object locking is pushed into policies for some object types, they
would otherwise occur more often.

goal of shipping 8.0 with MAC support in the default kernel. No policies
will be compiled in or enabled by default, but it will now be possible to
load them at boot or runtime without a kernel recompile.
While the framework is not believed to impose measurable overhead when no
policies are loaded (a result of optimization over the past few months in
HEAD), we'll continue to benchmark and optimize as the release approaches.
Please keep an eye out for performance or functionality regressions that
could be a result of this change.

count of the number of registered policies.
Rather than unconditionally locking sockets before passing them into MAC,
lock them in the MAC entry points only if mac_policy_count is non-zero.
This avoids locking overhead for a number of socket system calls when no
policies are registered, eliminating measurable overhead for the MAC
Framework for the socket subsystem when there are no active policies.
Possibly socket locks should be acquired by policies if they are required
for socket labels, which would further avoid locking overhead when there
are policies but they don't require labeling of sockets, or possibly
don't even implement socket controls.

bridge do a better job.
o move ether_ifdetach to the top of ieee80211_detach
o do not clear if_softc at the top of ieee80211_detach; we no longer need
this because we are safeguarded against calls coming back through if_ioctl
o simplify the bpf tracker now that we don't null if_softc
This also fixes an issue where having a bpf consumer active when a vap
is destroyed would cause a crash because bpf referenced free'd memory.

Some time ago Tom Rhodes sent me an email that he was willing to perform
various cleanups to the window(1) source code. After some discussion, we
both decided the best thing to do, was to move window(1) to the ports
tree. The application isn't used a lot nowadays, mainly because it has
been superseeded by screen, tmux, etc.
A couple of hours ago Tom committed window(1) to ports (misc/window), so
I'm removing it from the tree. I don't think people will really miss it,
but I'm describing the change in UPDATING anyway.

shm_dotruncate() and vnode_pager_setsize(). Specifically, if the length of
a shared memory object or a file is truncated such that the length modulo
the page size is between 1 and 511, then all of the page's dirty bits were
cleared. Now, a dirty bit is cleared only if the corresponding block is
truncated in its entirety.
and -delete (which implies depth-first traversal), avoid using -delete in
favour of -execdir.
This has a side-effect of not removing directories that contain files,
even if we delete all of those files, but IMHO that's a better option
than specifying all possible local filesystem types in this script.

These controllers use newer descriptor format and the new descriptor
format uses status LE to indicate the status of checksum. Rx
checksummed value used in previous controllers were very cryptic
and I failed to understand how to use them. In addition most
controllers in previous generations had Rx checksum offloading bug.
While I'm here introduce a MSK_FLAG_NORX_CSUM flag to bypass
checking Rx checksum offloading as Yukon FE+ A0 has status LE bug.
