musl - The musl libc tree (WIP / dev branches)

Age	Commit message (Collapse)	Author	Files	Lines
2011-06-30	simple rpath support (no token expansion yet) for dynamic linker	Rich Felker	1	-2/+8

2011-06-30	fill in junk in stropts.h	Rich Felker	1	-1/+123
	STREAMS are utterly useless as far as I can tell, but some software was apparently broken by the presence of stropts.h but lack of macros it's supposed to define...
2011-06-30	fix error in previous ld80 fpclassify commit	Rich Felker	1	-1/+1

2011-06-30	catch invalid ld80 bit patterns and treat them as nan	Rich Felker	1	-2/+2
	this should not be necessary - the invalid bit patterns cannot be created except through type punning. however, some broken gnu software is passing them to printf and triggering dangerous stack-smashing, so let's catch them anyway...
2011-06-30	fix logic in __fwriting	Rich Felker	1	-1/+1

2011-06-30	add and consolidate nasty stdio_ext junk	Rich Felker	4	-17/+84
	hopefully this resolves the rest of the issues with hideously nonportable hacks in programs that use gnulib.
2011-06-30	implement the nonstandard GNU function fpurge	Rich Felker	2	-0/+12
	this is a really ugly and backwards function, but its presence will prevent lots of broken gnulib software from trying to define its own version of fpurge and thereby failing to build or worse.
2011-06-30	fix buffer overrun in getgrent code when there are no group members	Rich Felker	1	-4/+8

2011-06-29	posix_memalign should fail if size is not a multiple of sizeof(void *)	Rich Felker	1	-1/+1

2011-06-29	avoid errors in ucontext.h when no feature test macros are defined	Rich Felker	1	-3/+5

2011-06-29	locking support for random() prng	Rich Felker	1	-7/+28
	these interfaces are required to be thread-safe even though they are not state-free. the random number sequence is shared across all threads.
2011-06-29	work around linux bug in mprotect	Rich Felker	1	-1/+5
	per POSIX: The mprotect() function shall change the access protections to be that specified by prot for those whole pages containing any part of the address space of the process starting at address addr and continuing for len bytes. on the other hand, linux mprotect fails with EINVAL if the base address and/or length is not page-aligned, so we have to align them before making the syscall.
2011-06-29	textrel support, cheap and ugly	Rich Felker	1	-0/+5

2011-06-28	release notes for 0.7.11v0.7.11	Rich Felker	1	-0/+22

2011-06-28	reclaim the memory wasted by dynamic linking for use by malloc	Rich Felker	1	-0/+39

2011-06-28	use type directives for fenv asm functions	Rich Felker	2	-0/+14

2011-06-28	use load address from elf header if possible	Rich Felker	1	-1/+1
	this is mostly useless for shared libs (though it could help for prelink-like purposes); the intended use case is for adding support for calling the dynamic linker directly to run a program, as in: ./libc.so ./a.out foo this usage is not yet supported.
2011-06-28	make dynamic linker relocate the main program image last, after all libs	Rich Felker	1	-0/+1
	prior to this change, copy relocations for initialized pointer variables would not reflect the relocated contents of the pointer.
2011-06-28	fix a few bugs from last dynamic linking build system commit	Rich Felker	1	-2/+2
	some cruft was left and DESTDIR was not being used correctly.
2011-06-27	minor updates to INSTALL documentation	Rich Felker	1	-0/+10

2011-06-27	cleanup shared library build system to be more $HOME-local-install friendly	Rich Felker	3	-16/+21
	the path for the dynamic linker is now configurable, and failure to install the symlink for it will not stop the build.
2011-06-27	further fixup dlfcn.h	Rich Felker	1	-4/+10

2011-06-27	match LSB/glibc constants for dynamic loader	Rich Felker	1	-4/+4

2011-06-26	fix stale pointer issue in dynamic linker with dlopen	Rich Felker	1	-0/+1

2011-06-26	don't leave the lock held on dlopen failure..	Rich Felker	1	-2/+2

2011-06-26	add RTLD_DEFAULT support	Rich Felker	1	-1/+2

2011-06-26	in dlopen: don't use null pointer	Rich Felker	1	-3/+3
	deps can be null if a library has no dependencies (such as libc itself)
2011-06-26	fix resolving symbols in objects loaded in RTLD_LOCAL mode	Rich Felker	1	-0/+11
	basically we temporarily make the library and all its dependencies part of the global namespace but only for the duration of performing relocations, then return them to their former state.
2011-06-26	experimental dlopen/dlsym and dynlink changes needed to support them	Rich Felker	1	-8/+125

2011-06-26	type directives for x86_64 math asm	Rich Felker	2	-0/+2

2011-06-26	error handling in dynamic linking	Rich Felker	1	-2/+19
	some of the code is not yet used, and is in preparation for dlopen which needs to be able to handle failure loading libraries without terminating the program.
2011-06-26	fix useless use of potentially-uninitialized mode variable in sem_open	Rich Felker	1	-1/+1

2011-06-26	eliminate OOB array hacks in malloc	Rich Felker	1	-46/+45

2011-06-26	use .type directives for math asm (needed for dynamic linking to work)	Rich Felker	15	-0/+26

2011-06-25	fix some symbol resolution issues in dynamic linker	Rich Felker	3	-4/+6
	1. search was wrongly beginning with lib itself rather than dso head 2. inconsistent resolution of function pointers for functions in plt
2011-06-25	fix dynamic linker issue in musl-gcc wrapper	Rich Felker	1	-1/+1

2011-06-25	wordexp cannot use we_offs unless WRDE_DOOFFS flag is set	Rich Felker	1	-1/+2
	previously, a potentially-indeterminate value from we_offs was being used, resulting in wrong we_wordc and subsequent crashes in the caller.
2011-06-25	XSI search.h API implementation by Szabolcs Nagy	Rich Felker	6	-4/+392

2011-06-25	handle library paths better (ignore empty path components, etc.)	Rich Felker	1	-3/+5

2011-06-25	move all limits that don't vary out of bits/limits.h, into main limits.h	Rich Felker	3	-53/+24

2011-06-25	fix possible (questionable) strict aliasing violations and ptr arith	Rich Felker	1	-3/+3

2011-06-25	const correctness in mq_notify	Rich Felker	1	-1/+1
	why did gcc allow this invalid assignment to compile in the first place?
2011-06-25	proper path searching for dynamic linker	Rich Felker	3	-14/+42
	first, use $LD_LIBRARY_PATH unless suid. if that fails, read path from /etc/ld-musl-$ARCH.path and fallback to a builtin default.
2011-06-25	optimize opendir using O_CLOEXEC	Rich Felker	1	-2/+1

2011-06-25	discard dso descriptors after performing relocations	Rich Felker	1	-0/+12
	eventually (once dlopen exists) this behavior will be conditional on dlopen/dlsym not being reachable.
2011-06-25	keep track of which dsos have been relocated	Rich Felker	1	-0/+1

2011-06-24	use soname in ld-musl.so to prevent filename appearing in DT_NEEDEDs	Rich Felker	1	-1/+1

2011-06-24	use symlink rather than bogus linker script for libc.so	Rich Felker	1	-2/+2
	the linker script caused a bogus DT_NEEDED entry
2011-06-23	adapt build/install/gcc-wrapper systems for dynamic linking support	Rich Felker	3	-9/+20

2011-06-23	prepare support for LD_LIBRARY_PATH (checking suid/sgid safety)	Rich Felker	1	-0/+6
	the use of this test will be much stricter than glibc and other typical implementations; the environment will not be honored whatsoever unless the program is confirmed non-suid/sgid by the aux vector the kernel passed in. no fallback to slow syscall-based checking is used if the kernel fails to provide the information; we simply assume the worst (suid) in this case and refuse to honor environment.
