* In sys_accept don't FILE_SET_MATURE the file if we got an error and we've freed it.art2002-05-231-2/+3
| | | | | | | | | 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.
* Fix my total blackout of the brain.art2002-02-121-3/+2
| | | | | | | | 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.
* Fix all users of getsock to use FREF/FRELE properly.art2002-02-121-62/+99

* - Rename FILE_{,UN}USE to FREF and FRELE. USE is a bad verb and we don't haveart2002-02-081-10/+15
| | | | | | | | | | | | | | 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)).
* makes a new accept() socket have the nonblock behavior.fgsch2001-12-271-2/+6
| | | | | slightly modified version from the original diff by theo, based on comments by niels@ and deraadt@; both ok'ed.

| | | | | | | | 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).
* - every new fd created by falloc() is marked as larval and should not be usedart2001-10-261-3/+6
| | | | | | | 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.

* bring in KAME IPv6 code, dated 19991208.itojun1999-12-081-8/+28
| | | | | | | | | 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).
