Age	Commit message (Collapse)	Author
2015-12-10	use geteuid to allow root to communicate with others.	Ted Unangst
	report from Jeunder Yu
2015-11-10	Split the intra-thread functionality from kill(2) into its own syscall	Philip Guenther
	thrkill(2), rolling the kill(2) syscall number with the ABI change to avoid breaking binaries during during the transition. thrkill(2) includes a 'tcb' argument that eliminates the need for locking in pthread_kill() and simplifies pthread_cancel(). Switch __stack_smash_handler() to use thrkill(2) and explicitly unblock SIGABRT. Minor bump to both libc and libpthread: make sure you install a new kernel! ok semarie@
2015-11-01	delete old lint ARGSUSED comments	Philip Guenther

2015-10-23	Merge the sigaction() and sigprocmask() overloads/wrappers from libpthread	Philip Guenther
	into libc, and move pthread_sigmask() as well (just a trivial wrapper). This provides consistent handling of SIGTHR between single- and multi-threaded programs and is a step in the merge of all the libpthread overloads, providing some ASM and Makefile bits that the other wrappers will need. ok deraadt@ millert@
2015-10-18	ld.so no longer needs or uses a bind lock, so stop setting it. This	Philip Guenther
	eliminates a chunk of complexity from the libpthread init and the fork wrapper, as it was the bind lock that needed prebinding before use.
2015-10-15	Handle F_ISATTY in the fcntl() stub as well	Theo de Raadt
	ok guenther
2015-05-19	Instead of testing for __ELF__ and/or vax, leave out the bits for interfacing	Philip Guenther
	with ld.so locking whenever building NOPIC pointless use of __ELF__ noted by brad@ ok miod@
2015-05-12	Put the right number of leading underscores in ___cerror and __cerror, for	Miod Vallat
	the sake of libpthread. Probably missed during the a.out->ELF switch, I can't believe this went unnoticed for so long.
2015-05-10	In the child after fork, the dl lock has to be forced as its inner spinlock	Philip Guenther
	may have been grabbed by another thread in the parent before the fork problem report from dcoppa@, ok kettenis@
2015-04-29	Delete the duplicated sched_{policy,param} members from the internal struct	Philip Guenther
	pthread and instead use the values from the embedded struct pthread_attr. For bonus points, pay attention to the sched_inherit attribute and possibly set the values from the parent thread. Problem noted by natano of bitrig.
2015-04-07	Make pthread_atfork() track the DSO that called it like atexit() does,	Philip Guenther
	unregistering callbacks if the DSO is unloaded. Move the callback handling from libpthread to libc, though libpthread still overrides the inner call to handle locking and thread-library reinitialization. Major version bump for both libc and libpthread. verification that this fixes various ports ajacoutot@ asm assistance miod@; ok millert@ deraadt@
2015-01-24	Add back <sys/param.h>; it's needed for MACHINE_STACK_GROWS_UP.	Mark Kettenis
	ok millert@, tobiasu@
2015-01-16	Move to the <limits.h> universe.	Theo de Raadt
	review by millert, binary checking process with doug, concept with guenther
2014-12-08	avoid void arithmetic. from david carlier	Ted Unangst

2014-11-16	Don't restart syscalls on SIGTHR. When a cancellation happens, we need to	Philip Guenther
	unroll to the cancellation check ok tedu@
2014-11-16	Don't assume __thrsigdivert() autorestarts on EINTR. This lets us check for	Philip Guenther
	cancellation properly when a handled (but not waited for) signal occurs ok tedu@
2014-08-31	accept4() should be a cancellation point.	Philip Guenther
	Update the list in the pthread_testcancel(3) manpage: several were missing. noted by miod@
2014-08-31	Declare and document getthrid()	Philip Guenther
	indirectly prodded by krw@
2014-08-09	Only need <stdint.h> and not <inttypes.h> here	Philip Guenther

2014-07-16	zap trailing newlines; "go for it" deraadt	Okan Demirmen

2014-07-10	__tfork_thread is in libc, so move the manpage over too	Philip Guenther
	ok deraadt@
2014-07-08	decouple struct uvmexp into a new file, so that uvm_extern.h and sysctl.h	Theo de Raadt
	don't need to be married. ok guenther miod beck jsing kettenis
2014-07-01	Use a flag on the pthread_t to indicate that the thread's stack was	Philip Guenther
	allocated by the kernel's execve bits. ok matthew@
2014-06-27	Fix mmap() flag usage: explicitly specify MAP_PRIVATE and drop useless	Matthew Dempsky
	MAP_FILE and MAP_HASSEMAPHORE flags. Discussed with deraadt, tedu, and kettenis
2014-06-23	Remove unintended statement from my copyright block	Philip Guenther

2014-05-02	- Adjust pthread_stackseg_np to return the page aligned addressable stack	Kurt Miller
	range. okay kettenis@, guenther@, deraadt@
2014-04-18	It's been a quarter century: we can assume volatile is present with that name.	Philip Guenther

2014-03-18	Retire hp300, mvme68k and mvme88k ports. These ports have no users, keeping	Miod Vallat
	this hardware alive is becoming increasingly difficult, and I should heed the message sent by the three disks which have died on me over the last few days. Noone sane will mourn these ports anyway. So long, and thanks for the fish.
2014-03-16	lint is dead (long live the lint!), so stop using it as a cpp conditional	Philip Guenther
	(namespace pollution!) or talking about its opinion on code. ok krw@
2013-12-18	Provide a random stackgrap on pthread frames. Use _STACKALIGNBYTES to	Theo de Raadt
	ensure the frames are aligned correctly. Discussed at length with guenther and kettenis ok kettenis, this is the right first step
2013-12-12	Fix static linking of libpthread: have crt0 invoke __init_tcb() if it's	Philip Guenther
	defined and we don't think ld.so has already done the TCB setup. ok and much discussion miod@
2013-12-11	revert to return EPERM for sem_init pshared until it really works	Ted Unangst
	reported by zhuk
2013-12-08	Reduce the random name length when sem_init is called with pshared	Federico G. Schwindt
	following what is recommended for mkstemp. This reduces the number of calls to sched_yield considerably. tedu@ ok.
2013-11-29	Don't try to reuse _initial_thread in the fork() wrapper, as the	Philip Guenther
	thread's existing handle must continue to be valid and it didn't fully 'change' the thread handle anyway. For pthread_main_np(), use a new flag, THREAD_ORIGINAL, to indicate that the flagged thread is the original thread for this process. Fixes some ConsoleKit failures according to aja@
2013-11-26	Remove unused var and include. Fix errno values as per spec.	Federico G. Schwindt
	NULL semaphore in sem_close(). Minor cosmetic changes. tedu@ zhuk@ ok
2013-11-22	don't use PAGE_SIZE, it is not portable. Ted can polish this after	Theo de Raadt
	if he wants, but let us get the tree building.
2013-11-21	remove dead assignment as reported by llvm.	Federico G. Schwindt

2013-11-21	handle the fourth vararg value to sem_open	Ted Unangst
	ok zhuk and presumably fgsch who just sent me a similar diff
2013-11-20	shared semaphore fixes. first, eliminate the sem inside a sem indirection.	Ted Unangst
	it's not needed (mindless holdover from earlier prototype). everything is simpler and sem_init shared semaphores even work now (confirmed by sthen). correct the einval checks to not deref a pointer before the null check. in sem_open, if we created the semaphore, we need to initialize the spinlock.
2013-11-20	oops, forgot about unnamed shared sems	Ted Unangst

2013-11-20	zhuk and i have slightly different styles. unify and consistify	Ted Unangst

2013-11-18	interprocess semaphores ala sem_open. mostly following in the pattern	Ted Unangst
	of shm_open. with some additions and fixes from zhuk.
2013-11-13	use sysctl vm.psstrings to calculate stack bounds, rather than USRSTACK.	Theo de Raadt
	long discussions with guenther, kurt, kettenis etc etc etc
2013-11-02	remove unnecessary spinlock that slowed down pthread_getspecific.	Ted Unangst
	original report and fix provided by John Carr. ok guenther kettenis
2013-10-23	In pthread_kill()/pthread_cancel(), hold the target thread's flags	Philip Guenther
	lock across the kill, so that it can't exit (and its tid be reused!) before the kill() discussed with tedu@ marc@
2013-10-04	_thread_sys_tcdrain() doesn't exist and isn't used	Philip Guenther

2013-08-28	Following the ARM manuals and cookbooks, ldrex/strex don't have implicit	Patrick Wildt
	barriers. Therefore it is required to add a memory berrier, so that it is ensured that all observers observed the change. ok rapha@
2013-08-26	Use %r27 as the thread control block pointer, allowing for __get_tcb() calls	Miod Vallat
	in libpthread to be optimized away. While there, follow DG/UX's example of using more than one register for thread purposes (after all, the ABI reserves four of them), and also use %r26 to store a pointer to the current thread's errno. Since it is not possible to initialize %r26 at thread creation without intrusive and potentially race-prone changes, have __tfork() reset %r26 to zero, and libpthread's __cerror lazy initialize it. As soon as %r26 is nonzero, it will be used instead of calling __errno(). This means that binaries linked against HEAD libpthread need to run on HEAD kernels, and we are belatedly jumping on the 64-bit time_t bump (since there are no 64-bit time_t m88k snapshots yet). Joint work with guenther@; "Your love of asm is sick and wrong, and yet beautiful." and ok guenther@
2013-08-13	Switch time_t, ino_t, clock_t, and struct kevent's ident and data	Philip Guenther
	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@
2013-08-06	Remove support for COMPILER_VERSION == gcc2.	Miod Vallat
	Change the logic depending upon COMPILER_VERSION everywhere, to assume gcc4 is the norm and to explicitely test for gcc3 when a different behaviour is required. No functional change intended. Be sure to `make install' in share/mk before attempting to do anything.
