2016-08-25Spliced TCP sockets become faster when the output part is runningAlexander Bluhm
as its own task thread. This is inspired by userland copy where a process also has to go through the scheduler. This gives the socket buffer a chance to be filled up and tcp_output() is called less often and with bigger chunks. When two kernel tasks share all the workload, the current scheduler implementation will hang userland processes on single cpu machines. As a workaround put a yield() into the splicing thread after each task execution. This reduces the number of calls of tcp_output() even more. OK tedu@ mpi@
2016-08-25Completely revert the M_WAIT change on the cluster allocation andAlexander Bluhm
bring back the behaviour of rev 1.72. Although allocating small mbufs when allocating an mbuf cluster fails seems suboptimal, this should not be changed as a side effect when introducing m_getuio(). OK claudio@

MCLGETI and large mbuf clusters. This should speed up local connections a fair bit. OK dlg@ and bluhm@ (after reverting the M_WAIT change on the cluster allocation)

2016-08-09When interrupted, connect() should leave the socket connecting in thePhilip Guenther

2016-07-19instead of messing about with pointer arithmetic, add an empty arrayTed Unangst
to the end of the defer structure. solves sizing and alignment concerns.
2016-07-14kern.usermount=1 is unsafe for everyone, since it allows any non-pledgedTheo de Raadt
program to call the mount/umount system calls. There is no way any user can be expected to keep their system safe / reliable with this feature. Ignore setting to =1, and after release we'll delete the sysctl entirely. ok lots of people

2016-07-14kevent validates that ident is a valid fd by getting the file. one sadTed Unangst
quirk: uint64 to int32 truncation can lead to false positives, and then later in the array sizing code, very big mallocs panic the kernel. add a check that the ident isn't larger than INT_MAX in the fd case. reported by Tim Newsham
2016-07-12The only valid flag for unmount(2) is MNT_FORCE, ignore any others.Todd C. Miller
Fixes a crash when MNT_DOOMED is passed in the flags to unmount(2) found by NCC Group. OK bluhm@
2016-07-12in the great unp_gc rewrite, a null check was lost. we have spent someTed Unangst
time investigating and arguing about whether a NULL fp is a bug or not, but what has become clear is that NULL fps get passed to unp_discard and have been for quite some time. restore old accomodating behavior by checking for null in unp_gc. ok deraadt kettenis

2016-07-06fix several places where calculating ticks could overflow.Ted Unangst
it's not enough to assign to an unsigned type because if the arithmetic overflows the compiler may decide to do anything. so change all the long long casts to uint64_t so that we start with the right type. reported by Tim Newsham of NCC. ok deraadt

2016-06-27Repair kill(2) on zombie processes.Jeremie Courreges-Anglas
kill(2) is supposed to find zombie processes, this probably got broken when the process reaper was introduced. As a temporary(tm) workaround, walk the list of zombie processes if we can't find the target pid in the main process list. Problem with zsh initially reported by Geoff Wozniak on misc@, analysis done by naddy@. ok kettenis@ tedu@

2016-06-27Restore the sys_o58_kill system call.Joel Sing
By keeping both the new (sys_kill/sys_thrkill) and old (sys_o58_kill) system calls for the OpenBSD 6.0 release, code that uses either of these mechanisms will work on both of the supported OpenBSD releases. This provides a clean transition for runtimes that make direct system calls (namely the Go programming language). This requires a minimal amount of non-intrusive code and does not block development progress within OpenBSD. ok deraadt@ guenther@

2016-06-23It is annoying that the dmesg buffer can overflow and loose messagesAlexander Bluhm
undetected during debugging. To make clear what happens, count the dropped bytes and write message buffer full to syslogd. This also helps to have a reliable log system. OK deraadt@ millert@ tedu@
2016-06-19Remove the lockmgr() API. It is only used by filesystems, where it is aMartin Natano
