Rich Felker	d89c9e8a63	use an accessor function for __libc data pointer when compiled as PIC prior to this change, a large portion of libc was unusable prior to relocation by the dynamic linker, due to dependence on the global data in the __libc structure and the need to obtain its address through the GOT. with this patch, the accessor function __libc_loc is now able to obtain the address of __libc via PC-relative addressing without using the GOT. this means the majority of libc functionality is now accessible right away. naturally, the above statements all depend on having an architecture where PC-relative addressing and jumps/calls are feasible, and a compiler that generates the appropriate code.	15 years ago
Rich Felker	4ee039f354	avoid referencing address of extern function from vdprintf this change is in preparation for upcoming PIC/shared library support. the intent is to avoid going through the GOT, mainly so that dprintf is operable immediately, prior to processing of relocations. having dprintf accessible from the dynamic linker will make writing and debugging the dynamic linker much easier.	15 years ago

Rich Felker	f552c792c7	include sys/sysmacros.h from sys/types.h when _GNU_SOURCE is defined	15 years ago
Rich Felker	b1b752372f	fix typo in inotify structure	15 years ago
Rich Felker	26031da0f8	make malloc(0) return unique pointers rather than NULL this change is made with some reluctance, but i think it's for the best. correct programs must handle either behavior, so there is little advantage to having malloc(0) return NULL. and i managed to actually make the malloc code slightly smaller with this change.	15 years ago
Rich Felker	598a0147cd	fix simple_malloc malloc(0) behavior not to return non-unique pointers	15 years ago
Rich Felker	a23baf586a	fix simple_malloc size restrictions do not allow allocations that overflow ptrdiff_t; fix some overflow checks that were not quite right but didn't matter due to address layout implementation.	15 years ago
Rich Felker	96f2197494	fix null pointer dereference introduced in last sigprocmask commit	15 years ago
Rich Felker	eee150f39c	make real symbols for the legacy (nonstandardized) utmp functions this is needed in the long term for ABI compatibility anyway, and in the immediate, it helps with building broken programs like GNU screen that try to prototype the functions themselves rather than using the header.	15 years ago
Rich Felker	d6a1e0c79e	resolve some header namespace non-issues after re-reading 2.2.2 of POSIX 2008, all of these are in the correct reserved namespaces and do not need protection.	15 years ago
Rich Felker	855df698c4	move the GNU siginfo renaming so it doesn't lead to mismatching names	15 years ago
Rich Felker	8668f033bc	fill in some missing siginfo stuff in signal.h	15 years ago
Rich Felker	2b43ef8fc7	make sys/param.h not depend on PATH_MAX and NAME_MAX this is a nonstandard header used only by backwards programs, but for some reason it's extremely popular. the recent namespace cleanup fixes broke it, because PATH_MAX and NAME_MAX will not be defined unless an approriate feature test macro has been defined. moreover, it's too late to just #define _GNU_SOURCE in param.h, since limits.h may have already been included. let's just hard-code standard values and be done with it.	15 years ago
Rich Felker	13e8459232	workaround gcc bug 46926 by providing a dumb sincos implementation note that this library itself is built with -ffreestanding so sincos.c should not be miscompiled even if the gcc used to compile musl has this bug.	15 years ago
Rich Felker	98e02144da	use rt_sigprocmask, not legacy sigprocmask, syscall in pthread exit code	15 years ago
Rich Felker	5316d083ec	fix typo in wordexp.h (note that the function is still unimplemented)	15 years ago
Rich Felker	4b1244a0bf	implement the remaining clock_* interfaces	15 years ago
Rich Felker	19eb13b9a4	race condition fix: block all signals before decrementing thread count the existence of a (kernelspace) thread must never have observable effects after the thread count is decremented. if signals are not blocked, it could end up handling the signal for rsyscall and contributing towards the count of threads which have changed ids, causing a thread to be missed. this could lead to one thread retaining unwanted privilege level. this change may also address other subtle race conditions in application code that uses signals.	15 years ago
Rich Felker	a49c119276	prevent sigprocmask/pthread_sigmask from blocking implementation signals this code was wrongly disabled because the old version was trying to be too clever and didn't work. replaced it with a simple version for now.	15 years ago
Rich Felker	fb11b6b85e	make pthread_exit run dtors for last thread, wait to decrement thread count	15 years ago
Rich Felker	69ecbd0f31	make mktemp match the historic behavior, and update functions that use it the historic mktemp is supposed to blank the template string on failure, rather than returning 0. just zero the first character so that mkstemp and mkdtemp can still retry with O(1) space requirement.	15 years ago

Rich Felker	b386d81862	prototypes for brk and sbrk	15 years ago
Rich Felker	ad2fe25041	support the ugly and deprecated ucontext and sigcontext header stuff... only the structures, not the functions from ucontext.h, are supported at this point. the main goal of this commit is to make modern gcc with dwarf2 unwinding build without errors. honestly, it probably doesn't matter how we define these as long as they have members with the right names to prevent errors while compiling libgcc. the only time they will be used is for propagating exceptions across signal-handler boundaries, which invokes undefined behavior anyway. but as-is, they're probably correct and may be useful to various low-level applications dealing with virtualization, jit code generation, and so on...	15 years ago
Rich Felker	e9417fffb3	add pthread_atfork interface note that this presently does not handle consistency of the libc's own global state during forking. as per POSIX 2008, if the parent process was threaded, the child process may only call async-signal-safe functions until one of the exec-family functions is called, so the current behavior is believed to be conformant even if non-ideal. it may be improved at some later time.	15 years ago
Rich Felker	446b4207cc	major improvements to temp file name generator use current time in nanoseconds and some potentially-random (if aslr is enabled) pointer values for the initial tempfile name generation, and step via a cheap linear prng on collisions. limit the number of retry attempts to prevent denial of service attacks even if an attacker can guess the filenames.	15 years ago
Rich Felker	3e9e30166f	reformat mkstemp like mkdtemp this is cleaner and makes it easy to impose a limit on the number of retries later if it seems desirable to do so.	15 years ago
Rich Felker	d5ca067c7b	add portable lchown (trivial to support and a few ancient things want it..)	15 years ago
Rich Felker	982a478433	prepare WHATSNEW for release	15 years ago

Rich Felker	127ab575fc	avoid deleting the lib/empty file	15 years ago
Rich Felker	e882756311	reorganize pthread data structures and move the definitions to alltypes.h this allows sys/types.h to provide the pthread types, as required by POSIX. this design also facilitates forcing ABI-compatible sizes in the arch-specific alltypes.h, while eliminating the need for developers changing the internals of the pthread types to poke around with arch-specific headers they may not be able to test.	15 years ago
Rich Felker	4fd159568a	new solution for empty lib dir (old one had some problems)	15 years ago
Rich Felker	a36164c474	improve Makefile handling of git checkouts with missing lib/ and config.mak	15 years ago
Rich Felker	187fe29d5b	make daemon try the operations that might fail before fork rather than after	15 years ago
Rich Felker	19e35c500b	daemon should check for failures and return -1	15 years ago
Rich Felker	b24bc15f5c	don't compare elements with themselves during qsort. this is actually a workaround for a bug in gcc, whereby it asserts inequality of the keys being compared...	15 years ago
Rich Felker	798a12ecc4	ucontext is no longer in the standard, so use gnu-friendly struct name note that this header is still bogus and needs a lot of work and factoring into arch-dependent parts...	15 years ago
Rich Felker	417dbe92cb	some gnu software wrongly uses "struct siginfo" instead of siginfo_t...	15 years ago
Rich Felker	56b784d603	add to pthread.h: pthread_mutex_timedlock and sched.h, time.h	15 years ago
Rich Felker	5cbd76c6b0	fix printf %n specifier - missing breaks had it clobbering memory	15 years ago
