2013-05-30Make interrupt handling in hibernate resume MI by providing MD-specificMike Larkin
functions to enable and disable interrupts, if needed. If a platform doesnt need interrupt handling in this way, the MD function can be a no-op. discussed with pirofti and deraadt
2013-05-30tiny change to support two poison values based on page addrTed Unangst
2013-05-30Enforce ca_activate tree-walks over the entire heirarchy for all events,Theo de Raadt
cleaning up some shutdown-hook related code on the way. (A few drivers related to sparc are still skipped at kettenis' request) ok kettenis mlarkin, tested by many others too

2013-05-07Merge from FreeBSD, r191313Philip Guenther
--------------------------- On the exit of the child process which parent either set SA_NOCLDWAIT or ignored SIGCHLD, unconditionally wake up the parent instead of doing this only when the child is a last child. This brings us in line with other U**xes that support SA_NOCLDWAIT. If the parent called waitpid(childpid), then exit of the child should wake up the parent immediately instead of forcing it to wait for all children to exit. --------------------------- ok tedu@, millert@
2013-05-06restore original gangster lockstatus return values for compatTed Unangst
2013-05-03switch the malloc and pool freelists to using xor simpleq.Ted Unangst
this adds a tiny bit more protection from list manipulation.

2013-04-29Extend P_SIGSUSPEND handling in userret() to properly restore theMatthew Dempsky
sigmask even if there are no pending signals under the temporary sigmask. Refactor existing select() and poll() system calls to introduce the pselect() and ppoll() system calls. Add rthread wrappers for pselect() and ppoll(). While there, update cancellation point comments to reflect recent fdatasync() addition. Minor bumps for libc and librthread due to new symbols. ok guenther, millert, deraadt, jmc

2013-04-24When a ucom(4) is removed, it frees the tty with ttyfree(). However ifNicholas Marriott
anyone is waiting with kqueue their knotes may still have a reference to the tty and later try to use it in the filt_tty* functions. To avoid this, walk the knotes in ttyfree(), remove them from the tty's list and invalidate them by setting kn_hook to NODEV. The filter functions can then check for this and safely ignore the knotes. ok tedu matthieu
2013-04-24When attaching disks, feed the disklabel's checksum toBret Lambert
the random pool as unique-esque-but-not-secret data. inspired by conversations with tedu@/deraadt@ ok deraadt@

2013-04-17check that the pool we are about to init isn't already on the list inTed Unangst
order to detect double init mistakes. add a similar check and rearrange pool_destory to detect the opposite mistake.

2013-04-15regenJoel Sing
2013-04-15Add an f_mntfromspec member to struct statfs, which specifies the name ofJoel Sing
the special provided when the mount was requested. This may be the same as the special that was actually used for the mount (e.g. in the case of a device node) or it may be different (e.g. in the case of a DUID). Whilst here, change f_ctime to a 64 bit type and remove the pointless f_spare members. Compatibility goo courtesy of guenther@ ok krw@ millert@

2013-04-09Add a magic number to the head of the signature block. Check for magicMike Larkin
number match during signature block read during speculative unhibernate on boot. If the magic number matches but we have otherwise chosen to not unhibernate (due to kernel/memory mismatch), clear the signature block early to avoid accidentally trying to unhibernate on subsequent boots. This prevents accidental unhibernates and endless unhibernate/reboot cycles. Add a define for HIBERNATE_DEBUG for various debugging printfs (disabled by default). Finally, change some KASSERTs to warning printfs (they probably shouldn't have been KASSERTs in the first place). "looks good" deraadt@

2013-04-04Do not allow the listen(2) syscall for an already connected socket.Alexander Bluhm
This would create a weird set of states in TCP. FreeBSD has the same check. Issue found by and OK guenther@
2013-04-01Make setrlimit() return EINVAL if rlim_cur > rlim_max, per POSIX.Philip Guenther
Use limfree() instead of decrementing the reference counter directly. ok kettenis@

2013-03-30vrele() is a tricky beast. it can sleep if the refcount hits zero,Ted Unangst
leaving us with a free type function that isn't atomic. deal with this by erasing any reachable pointers to the vnode first, then free it. ok deraadt guenther

ok deraadt guenther
2013-03-28When updating fd_cdir or fd_rdir, put the new pointer in placePhilip Guenther
_before_ vrele()'ing the old one, so that you can't catch the process with a vnode with no references. Similarly, in checkdirs(), just count the needed releases and do them all at the end. (I think I saw this in FreeBSD.) Original problem encountered by landry@ (yay for backtrace) ok tedu@ deraadt@
2013-03-28Handle the pathconf _PC_PATH_MAX, _PC_PIPE_BUF, _PC_ASYNC_IO,Philip Guenther
_PC_PRIO_IO, and _PC_SYNC_IO names in VOP_PATHCONF(), as they're fs-independent for us. Since we don't support latter three on any fs, we can also define the related _POSIX_{ASYNC,PRIO,SYNC}_IO symbols in <unistd.h> (via sys/unistd.h) with value -1. Also, zap pointless tty-only values from procfs(!). ok beck@, deraadt@
2013-03-27Move soidle() into the big #ifdef SOCKET_SPLICE block to have itAlexander Bluhm
all in one place. Saves one additional #ifdef, no functional change. OK mikeb@
