allowed. It takes three int * arguments indicating domain, type, and
protocol. Replace previous KAUTH_REQ_NETWORK_SOCKET_RAWSOCK with it (but
keep it still).
Places that used to explicitly check for privileged context now don't
need it anymore, so I replaced these with XXX comment indiacting it for
future reference.
Documented and updated examples as well.
Brought up on tech-kern@ some ~2 months ago, didn't seem to be an
objection; brought up again recently and no objection either... this is
not too intrusive and I've been running with this for a while.
supported. This adds further differentiation between which argument to
socket(2) caused the error. No longer are invalid domain (address family)
errors classified as ENOPROTOSUPPORT errors. This should make socket(2)
conform to current POSIX and X/Open standards. Fixes PR/33676.
- use vmspace rather than proc or lwp where appropriate.
the latter is more natural to specify an address space.
(and less likely to be abused for random purposes.)
- fix a swdmover race.
chgsbsize() as mentioned in the PR can be called from an interrupt context
via tcp_close(). Avoid calling uid_find() in chgsbsize().
- Instead of storing so_uid in struct socketvar, store *so_uidinfo
- Add a simple lock to struct uidinfo.
- don't use managed mappings/backing objects for wired memory allocations.
save some resources like pv_entry. also fix (most of) PR/27030.
- simplify kernel memory management API.
- simplify pmap bootstrap of some ports.
- some related cleanups.

Add a new explicit `struct proc *p' argument to socreate(), sosend().
Use that argument instead of curproc. Follow-on changes to pass that
argument to socreate(), sosend(), and (*so->so_send)() calls.
These changes reviewed and independently recoded by Matt Thomas.
Changes to soreceive() and (*dom->dom_exernalize() from Matt Thomas:
pass soreceive()'s struct uio* uio->uio_procp to unp_externalize().
Eliminate curproc from unp_externalize. Also, now soreceive() uses
its uio->uio_procp value, pass that same value downward to
((pr->pru_usrreq)() calls for consistency, instead of (struct proc * )0.
Similar changes in sys/nfs to eliminate (most) uses of curproc,
either via the req-> r_procp field of a struct nfsreq *req argument,
or by passing down new explicit struct proc * arguments.
Reviewed by: Matt Thomas, posted to tech-kern.
NB: The (*pr->pru_usrreq)() change should be tested on more (all!) protocols.

Convert struct session, ucred and lockf to pools.

every field; some need to stay around.
Fixes a bug where by calling shutdown() on a socket with knotes
will cause the kernel to panic when the kernel closes the socket.
Other access, such as calling kevent() may also trigger the panic.
Debugged with help from Jason and Allen. Patch reviewed by same plus
Itojun and Matt Thomas.
This problem seems to be the same one that FreeBSD saw in their PR
number 54331.
Kernel version _not_ bumped as we will piggyback the bump earlier today.
