not removing tabs before "__P((", and not outdenting continuation lines
to preserve non-KNF lining up of code with parentheses. Switch to KNF
formatting and/or rewrap the whole prototype in some cases.
not blocked by raising the pil, a reciever may be interrupted while holding
a spinlock. If the sender does not defer interrupts throughout the entire
operation it may be interrupted and try to acquire a spinlock held by a
reciever, leading to a deadlock due to the synchronization used by the
ipi handlers themselves.

as a macro w/o messing things up. This is really an abuse and we will back
this out as soon as the abusers have been fixed. Add a comment to this
effect.
With this change, the XFree86-4 port now builds.
code that is still not safe. suser() reads p_ucred so it still needs
Giant for the time being. This should allow kern.giant.proc to be set
to 0 for the time being.
- expr must conform to the Utility Syntax Guidelines, so use
getopt() to eat the (non-existent) options.
- Use the Standard type intmax_t for arithmetic.
- If an argument cannot be *completely* converted to an integer, then
it is a string.
Additionally make some style cleanups near the modified lines. This
utility is still not completely style-compliant.
rpcgen can't really make those fields const because the remote side might
want to munge them, so we need to pass non-const in. Hackish, but should
work.
Move the network code from using cr_cansee() to check whether a
socket is visible to a requesting credential to using a new
function, cr_canseesocket(), which accepts a subject credential
and object socket. Implement cr_canseesocket() so that it does a
prison check, a uid check, and add a comment where shortly a MAC
hook will go. This will allow MAC policies to seperately
instrument the visibility of sockets from the visibility of
processes.

count never being decremented. Just flood ping the localhost and
watch refcnt of the 127.0.0.1 route with netstat(1).

Back out ip_output.c,v 1.143 and ip_mroute.c,v 1.69 that allowed
ip_output() to be called with a NULL route pointer. The previous
paragraph shows why this was a bad idea in the first place.

to test req->td for NULL values and then do somewhat more bizarre things
relating to securelevel special-casing and suser checks. Remove the
testing and conditional security checks based on req->td!=NULL, and insert
a KASSERT that td != NULL. Callers to sysctl must always specify the
thread (be it kernel or otherwise) requesting the operation, or a
number of current sysctls will fail due to assumptions that the thread
exists.
