| | | | | | | | | 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@
* Move p_emul and p_sigcode from proc to process.guenther2014-03-261-7/+7
| | | | | | | | | Tweak the handling of ktrace EMUL when changing ktracing: only generate one per process (not one per thread) and pass the correct proc pointer down to the VFS layer. Permit generating of NAMI and CSW records inside ktrace(2) itself. ok deraadt@ millert@

* Start to deal with the time_t change's effect on compat/linux:guenther2013-10-251-55/+95
| | | | | | | | | | | | | | - add Linux versions of struct rusage, timeval, and itimerval and conversion functions for them - add Linux versions of getrusage(), gettimeofday(), {set,get}itimer(), and nanosleep() - fix various inconsistencies in naming of Linux versions of types and conversion functions - add mappings for LINUX_CLOCK_{PROCESS,THREAD}_CPUTIME_ID to the native versions Originally written months ago as part of the time_t work; long memory, prodding, and ok from pirofti@
* Switch time_t, ino_t, clock_t, and struct kevent's ident and dataguenther2013-08-131-6/+5
| | | | | | | | | | | | | | | | | | | | 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@
* compat_linux: Add support for future time_t and ino_t size enlargements.pirofti2013-05-101-10/+39
| | | | Reviewed by guenther@.
* Remove the lack of gettid() implementation. Okay tedu@pirofti2012-06-081-1/+8
| | | | Looks right to jasper@ as well.
* Add emulation support for fstatfs64.pirofti2012-05-231-1/+30
| | | | Okay matthew@.
* Add support for statfs64.pirofti2012-05-231-11/+91
| | | | | | | | | While at it get rid of some magic numbers and add support for more filesystem types (like NTFS, AFS etc.). Suggestions and feedback from ajacoutot@, jsing@ and matthew@. Okay matthew@.

* Remove the sys_opipe() kernel entry point. sys_pipe() is the future.matthew2011-07-081-47/+1
| | | | | | | While here, switch compat_linux to just use sys_pipe() rather than incorrectly wrapping sys_opipe(). ok tedu@, miod@

* Move the bufcachepercent setting code to MI locations -- set it to 42%deraadt2011-06-051-2/+2
| | | | | | | for now; that is unlikely to hit some of the remaining starvation bugs. Repair the bufpages calculation too; i386 was doing it ahead of time (incorrectly) and then re-calculating it. ok thib

* Correct the links between threads, processes, pgrps, and sessions,guenther2010-07-261-5/+5
| | | | | | | | | 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
* Merge from NetBSD: "Linux's getsid(2) does in fact return a pid,guenther2010-06-301-28/+1

* Fix various cases of stackgap_alloc() size arguments not being computedmiod2009-09-051-2/+2
| | | | | correctly, usually yielding the right value on 32 bit machines because sizeof int == sizeof pointer.
* First pass at removing clauses 3 and 4 from NetBSD licenses.ray2008-06-261-8/+1
| | | | | | | | | Not sure what's more surprising: how long it took for NetBSD to catch up to the rest of the BSDs (including UCB), or the amount of code that NetBSD has claimed for itself without attributing to the actual authors. OK deraadt@

* This moves access to wall and uptime variables in MI code,tholo2004-06-241-17/+15
| | | | | | | | | | | | | | encapsulating all such access into wall-defined functions that makes sure locking is done as needed. It also cleans up some uses of wall time vs. uptime some places, but there is sure to be more of these needed as well, particularily in MD code. Also, many current calls to microtime() should probably be changed to getmicrotime(), or to the {,get}microuptime() versions. ok art@ deraadt@ aaron@ matthieu@ beck@ sturm@ millert@ others "Oh, that is not your problem!" from miod@

* change arguments to suser. suser now takes the process, and a flagstedu2003-08-151-2/+2
| | | | | | | | | 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@

| | | | | | | | | | use them to correctly emulate linux brk. update to TNF copyright in linux_exec.c. from netbsd, mostly from a diff by Kurt Miller in pr3318. this should fix java. no regressions in testing by kurt and sturm@. be prepared for "proc size mismatch" -- recompile ps and friends. ok deraadt@
* Bring back setreuid(2) and setregid(2) as first class syscallsmillert2003-01-301-5/+5
| | | | | | | (but still implemented via setres[ug]id(2)). Basically this just moves them from COMPAT_43 into kern_prot.c. Also fixes a typo in my old implementation. The userland portion will follow in a few days. deraadt@ OK
* Now that we have [gs]etres[ug]id() as a native system call, use itmillert2002-10-301-171/+58
| | | | | | for HP-UX, FreeBSD, and Linux emulations. Note that Linux has two versions of these system calls. One for 16bit uids and another for 32bit uids.
