2003-07-21remove caddr_t casts. it's just silly to cast something when the functionTed Unangst
takes a void *. convert uiomove to take a void * as well. ok deraadt@

rescinded 22 July 1999. Proofed by myself and Theo.
2002-08-23Just like getvnode, make getsock FREF the file so that we can't get awayArtur Grabowski
with not refing it. Eyeballed by lurene@daemonkitty.net, fries@, nordin@ and fries@ Some additional cleanups by nordin@
2002-05-23In sys_accept don't FILE_SET_MATURE the file if we got an error and we've ↵Artur Grabowski
freed it. Noticed by enami@netbsd in a recent discussion on tech-kern@netbsd. Thanks to miod@ for helping me understand my code and realize that what the discussion was originally about (a diff by itojun@) didn't apply to us because I tweaked the semantics of closef() to solve the problem automagically for us (and I forgot about it). miod@ ok.
2002-02-12Fix my total blackout of the brain.Artur Grabowski
I rearrange half of this function to properly handle unlocking in one error case, then I forget to handle that error case. I even had a regression test written for this! In other words: fix accept(2) to unlock when it runs out of fds.
2002-02-12Fix all users of getsock to use FREF/FRELE properly.Artur Grabowski
2002-02-11In {send,recv}msg allow zero sized message. We can have control data.Artur Grabowski
2002-02-08- Rename FILE_{,UN}USE to FREF and FRELE. USE is a bad verb and we don't haveArtur Grabowski
the same semantics as NetBSD anyway, so it's good to avoid name collissions. - Always fdremove before freeing the file, not the other way around. - falloc FREFs the file. - have FILE_SET_MATURE FRELE the file (It feels like a good ortogonality to falloc FREFing the file). - Use closef as much as possible instead of ffree in error paths of falloc:ing functions. closef is much more careful with the fd and can deal with the fd being forcibly closed by dup2. Also try to avoid manually calling *fo_close when closef can do that for us (this makes some error paths mroe complicated (sys_socketpair and sys_pipe), but others become simpler (sys_open)).
2001-12-27makes a new accept() socket have the nonblock behavior.Federico G. Schwindt
slightly modified version from the original diff by theo, based on comments by niels@ and deraadt@; both ok'ed.

based on freebsd. okay art@ markus@
2001-11-27change socket connection queues to use TAILQ_Niels Provos
from NetBSD: Wed Jan 7 23:47:08 1998 UTC by thorpej Make insertion and removal of sockets from the partial and incoming connections queues O(C) rather than O(N).
2001-10-26 - every new fd created by falloc() is marked as larval and should not be usedArtur Grabowski
any anyone. Every caller of falloc matures the fd when it's usable. - Since every lookup in the fd table must now check this flag and all of them do the same thing, move all the necessary checks into a function - fd_getfile.

2001-09-17Don't treated return length of recvfrom() as a size_t... it's a socklen_t.Jason Wright

okay art@, millert@
2000-11-10Change the ktrace interface functions from taking the trace vnode to taking theArtur Grabowski
traced proc. The vnode is in the proc and all functions need the proc.

IPv6 advanced API). sync with netbsd.

1999-12-08bring in KAME IPv6 code, dated 19991208.Jun-ichiro itojun Hagino
replaces NRL IPv6 layer. reuses NRL pcb layer. no IPsec-on-v6 support. see sys/netinet6/{TODO,IMPLEMENTATION} for more details. GENERIC configuration should work fine as before. GENERIC.v6 works fine as well, but you'll need KAME userland tools to play with IPv6 (will be bringed into soon).
1999-07-13introduce fdremove() to mark a file descriptor as unused. fdremove makesNiels Provos
sure that the fd_freefile hints stay in sync, otherwise free file descriptors might not be overlooked by fdalloc(); ok millert@

namelen is uninitialized.
1999-02-14readv/writev with iov_len == 0 is legal (was already ok in uipc_syscalls.c).Todd C. Miller
Make the check more readable by comparing against SSIZE_MAX instead of checking for wraparound. This is safe because SSIZE_MAX * 2 <= SIZE_T_MAX. Fixes recno problems in the db routines exposed by a perl test.
