2013-09-14Correct the handling of I/O of >=2^32 bytes and the ktracing there ofPhilip Guenther
by using size_t/ssize_t instead of int/u_int to handle I/O lengths in uiomove(), vn_fsizechk(), and ktrgenio(). Eliminate the always-zero 'error' argument to ktrgenio() at the same time.
2013-04-05remove some obsolete castsTed Unangst
2012-10-17In sys_accept(), don't sleep between pulling the new socket from thePhilip Guenthe
queue and calling soaccept(), so that the socket can't get torn down by a TCP RST in the middle and trigger "panic: soaccept: !NOFDREF", as seen by halex@ Analysis, original diff, and ok bluhm@
2012-05-06Change accept(), recvfrom(), recvmsg(), getsockname(), andMatthew Dempsky
getpeername() to return the untruncated address length in *addrlen instead of the number of bytes copied out. This matches POSIX's requirements and allows userland applications to detect when the returned address was truncated. ok guenther

2010-07-03Fix the naming of interfaces and variables for rdomains and rtablesPhilip Guenthe
and make it possible to bind sockets (including listening sockets!) to rtables and not just rdomains. This changes the name of the system calls, socket option, and ioctl. After building with this you should remove the files /usr/share/man/cat2/[gs]etrdomain.0. Since this removes the existing [gs]etrdomain() system calls, the libc major is bumped. Written by claudio@, criticized^Wcritiqued by me
2010-06-30Add getsockopt SOL_SOCKET SO_PEERCRED support. This behaves similar toTheo de Raadt
getpeereid(2), but also supplies the remote pid. This is supplied in a 'struct sockpeercred' (unlike Linux -- they showed how little they know about real unix by calling theirs 'struct ucred'). ok guenther ajacoutot
2009-12-23The process's rdomain should be, well, per-process and not per-rthread,Philip Guenthe
so put it in struct process instead of struct proc. While at it, move the p_emul member inside struct proc so that it gets copied automatically instead of requiring manual assignment. ok deraadt@

2008-12-16Move the functionality of psignal() to a new function ptsignal()Philip Guenthe
that takes an additional argument "type" that indicates whether the signal is for the process, just a particular thread, or propagated to a thread because it's not caught or blocked. psignal() becomes a wrapper that does the first of those. So that sys_kill() can tell apart signals for the process and signals for the process's original thread, the tid of the original thread is defined as its pid + THREAD_PID_OFFSET. ok tedu@ art@ andreas@ kurt@ "better early than late" deraadt@
2008-05-23Deal with the situation when TCP nfs mounts timeout and processesThordur I. Bjornsson
get hung in nfs_reconnect() because they do not have the proper privilages to bind to a socket, by adding a struct proc * argument to sobind() (and the *_usrreq() routines, and finally in{6}_pcbbind) and do the sobind() with proc0 in nfs_connect. OK markus@, blambert@. "go ahead" deraadt@. Fixes an issue reported by bernd@ (Tested by bernd@). Fixes PR5135 too.

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)).

2001-10-26 - 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.
