* refactor pledge_*_check and pledge_fail functionssemarie2015-11-011-6/+6
| | | | | | | | | | | | | | - rename _check function without suffix: a "pledge" function called from anywhere is a "check" function. - makes pledge_fail call the responsability to the _check function. remove it from caller. - make proper use of (potential) returned error of _check() functions. - adds pledge_kill() and pledge_protexec() with and OK deraadt@

* Setting fcntl(F_SETOWN) for a pipe failed with inappropriate ioctlbluhm2015-10-211-1/+11
| | | | | | | for device. In sys_fcntl() the ioctl(TIOCSPGRP) is called, but the pipe expects SIOCSPGRP. Sockets have a specal case for the same reason, so adapt the special code for pipes. OK millert@

* isatty() is used by stdio to determine the buffering mode. Add a F_ISATTYderaadt2015-05-171-1/+11
| | | | | | | option to fcntl(), so that isatty() can use this rather than than the bloated ioctl() interface. Reducing uses of ioctl() by libc makes it easier to constrain programs with various kinds of systrace sandboxes. ok guenther, previously discussed as a concept with nicm

* Indroduce fd_getfile_mode() and use it were fd_getfile() is directlympi2015-04-301-1/+16
| | | | | | | followed by a mode check. This will simplify the ref/unref dance as soon as fd_getfile() will increment fp's reference counter. Idea from and ok guenther@, ok millert@

* primary change: move uvm_vnode out of vnode, keeping only a pointer.tedu2014-12-161-1/+2
| | | | | | objective: vnode.h doesn't include uvm_extern.h anymore. followup changes: include uvm_extern.h or lock.h where necessary. ok and help from deraadt

| | | | | | | when creating them: pipe2(), dup3(), accept4(), MSG_CMSG_CLOEXEC, SOCK_CLOEXEC. Includes SOCK_NONBLOCK support. ok matthew@

* Use sizeof(struct file *) consistently for memcpy()'ing fd_ofiles.matthew2014-06-151-2/+2
| | | | Pointed out by Jean-Philippe Ouellet.
* Move from struct proc to process the reference-count-holding pointersguenther2014-05-151-16/+7
| | | | | | | | | | to the process's vmspace and filedescs. struct proc continues to keep copies of the pointers, copying them on fork, clearing them on exit, and (for vmspace) refreshing on exec. Also, make uvm_swapout_threads() thread aware, eliminating p_swtime in kernel. particular testing by ajacoutot@ and sebastia@
* revert falloc change, as it causes all new processes to get stuck after a whileespie2014-04-121-43/+14
| | | | | | | | | | | (race condition ?) problem noticed by me, aja, sthen, brynet, rpe. vanishing after this revert, okay aja@, sthen@ tedu, you probably want to look into re-checking the fcreate/fpublish addition first, then if it's stable, see about tweaking doopenat ?
* Eliminates struct pcred by moving the real and saved ugids intoguenther2014-03-301-2/+2
| | | | | | | | | struct ucred; struct process then directly links to the ucred Based on a discussion at c2k10 or so before noting that FreeBSD and NetBSD did this too. ok matthew@
* split falloc into two functions, the allocation and the publication.tedu2014-03-081-14/+43
| | | | | | | | | | the first part is likely to fail, but we can generally prevent the second part from failing. use these two functions to drop the fdp lock around vn_open in sys_open, but still maintain the original semantics of allocate then open. the goal here is to fix the blocked fifo deadlock in a threaded program. testing volunteers in short supply, resorting to conscription
* Snapshots for all archs have been built, so remove the T32 codeguenther2013-09-141-27/+1

* Switch time_t, ino_t, clock_t, and struct kevent's ident and dataguenther2013-08-131-2/+27
| | | | | | | | | | | | | | | | | | | | members to 64bit types. Assign new syscall numbers for (almost all) the syscalls that involve the affected types, including anything with time_t, timeval, itimerval, timespec, rusage, dirent, stat, or kevent arguments. Add a d_off member to struct dirent and replace getdirentries() with getdents(), thus immensely simplifying and accelerating telldir/seekdir. Build perl with -DBIG_TIME. Bump the major on every single base library: the compat bits included here are only good enough to make the transition; the T32 compat option will be burned as soon as we've reached the new world are are happy with the snapshots for all architectures. DANGER: ABI incompatibility. Updating to this kernel requires extra work or you won't be able to login: install a snapshot instead. Much assistance in fixing userland issues from deraadt@ and tedu@ and build assistance from todd@ and otto@

| | | | | | Having done that, dupfdopen() has to handle a possible race. ok matthew@ krw@
* Cleanup O_CLOEXEC handling and make sure UF_EXCLOSE is set correctlymatthew2012-05-211-2/+3
| | | | | | | | | | when opening /dev/fd/* (i.e., UF_EXCLOSE is now set iff O_CLOEXEC is set, rather than copying UF_EXCLOSE from the file descriptor being dup'd). Also, add support for O_CLOEXEC and O_DIRECTORY to fhopen(). ok krw, guenther; feedback from millert; testing and bug finding by krw
* Remove the "vn_open() returning ENXIO means dup+close" hook thatguenther2012-05-141-48/+14
| | | | | | | was used by the now defunct portalfs. Zero out fd_ofileflags[fd] when allocating an fd instead of when releasing it. ok krw@ matthew@
* Eliminate the f_usecount ref count in struct file; instead of sleepingguenther2012-05-011-30/+16
| | | | | | | | | at the top of closef() until all in-progress calls finish, just do the advisory locking bits required of close() by POSIX and let whichever thread has the last reference do the call to the file's fo_close() method and the final cleanup. lots of discussion with deraadt@ and others; worked out with and ok krw@

* Correct the links between threads, processes, pgrps, and sessions,guenther2010-07-261-4/+4
| | | | | | | | | so that the process-level stuff is to/from struct process and not struct proc. This fixes a bunch of problem cases in rthreads. Based on earlier work by blambert and myself, but mostly written at c2k10. Tested by many: deraadt, sthen, krw, ray, and in snapshots
