| | | | | | | | make it a list of processes, and change P_NOZOMBIE and P_STOPPED from thread flags to process flags. Add allprocess list for the code that just wants to see processes. ok tedu@
* Move the declarations for dogetrusage(), itimerround(), and dowait4()guenther2013-10-251-3/+1
| | | | | | | | | | to sys/*.h headers so that the compat/linux code can use them. Change dowait4() to not copyout() the status value, but rather leave that for its caller, as compat/linux has to translate it, with the side benefit of simplifying the native code. Originally written months ago as part of the time_t work; long memory, prodding, and ok from pirofti@

| | | | | | | | | | | | | | | | | | | | 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@

| | | | | | | | | 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

* This patch is mortly art's work and was done *a year* ago. Art wants to thankniklas2005-05-251-2/+2
| | | | | | | | | | | | | | | | everyone for the prompt review and ok of this work ;-) Yeah, that includes me too, or maybe especially me. I am sorry. Change the sched_lock to a mutex. This fixes, among other things, the infamous "telnet localhost &" problem. The real bug in that case was that the sched_lock which is by design a non-recursive lock, was recursively acquired, and not enough releases made us hold the lock in the idle loop, blocking scheduling on the other processors. Some of the other processors would hold the biglock though, which made it impossible for cpu 0 to enter the kernel... A nice deadlock. Let me just say debugging this for days just to realize that it was all fixed in an old diff noone ever ok'd was somewhat of an anti-climax. This diff also changes splsched to be correct for all our architectures.

| | | | | | | | | argument. old cred only calls user suser_ucred. this will allow future work to more flexibly implement the idea of a root process. looks like something i saw in freebsd, but a little different. use of suser_ucred vs suser in file system code should be looked at again, for the moment semantics remain unchanged. review and input from art@ testing and further review miod@
