* zero precision with zero value should not inhibit prefix/width printingRich Felker2011-07-041-1/+4
|
* printf("%#x",0) should print 0 not 0x0Rich Felker2011-07-041-1/+1
|
* iconv was not returning -1 on most failureRich Felker2011-07-031-0/+2
| | | | | this broke most uses of iconv in real-world programs, especially glib's iconv wrappers.
* 0.7.12 release notes v0.7.12Rich Felker2011-07-031-0/+16
|
* fix dlopen UB due to longjmp/volatile rules violationRich Felker2011-07-011-1/+1
|
* res_search symbol, aliased to res_query for now (better than nothing)Rich Felker2011-06-301-0/+3
|
* simple rpath support (no token expansion yet) for dynamic linkerRich Felker2011-06-301-2/+8
|
* fill in junk in stropts.hRich Felker2011-06-301-1/+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...
* fix error in previous ld80 fpclassify commitRich Felker2011-06-301-1/+1
|
* catch invalid ld80 bit patterns and treat them as nanRich Felker2011-06-301-2/+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...
* fix logic in __fwritingRich Felker2011-06-301-1/+1
|
* add and consolidate nasty stdio_ext junkRich Felker2011-06-304-17/+84
| | | | | hopefully this resolves the rest of the issues with hideously nonportable hacks in programs that use gnulib.
* implement the nonstandard GNU function fpurgeRich Felker2011-06-302-0/+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.
* fix buffer overrun in getgrent code when there are no group membersRich Felker2011-06-301-4/+8
|
* posix_memalign should fail if size is not a multiple of sizeof(void *)Rich Felker2011-06-291-1/+1
|
* avoid errors in ucontext.h when no feature test macros are definedRich Felker2011-06-291-3/+5
|
* locking support for random() prngRich Felker2011-06-291-7/+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.
* work around linux bug in mprotectRich Felker2011-06-291-1/+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.
* textrel support, cheap and uglyRich Felker2011-06-291-0/+5
|
* release notes for 0.7.11 v0.7.11Rich Felker2011-06-281-0/+22
|
* reclaim the memory wasted by dynamic linking for use by mallocRich Felker2011-06-281-0/+39
|
* use type directives for fenv asm functionsRich Felker2011-06-282-0/+14
|
* use load address from elf header if possibleRich Felker2011-06-281-1/+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.
* make dynamic linker relocate the main program image last, after all libsRich Felker2011-06-281-0/+1
| | | | | prior to this change, copy relocations for initialized pointer variables would not reflect the relocated contents of the pointer.
* fix a few bugs from last dynamic linking build system commitRich Felker2011-06-281-2/+2
| | | | some cruft was left and DESTDIR was not being used correctly.
* minor updates to INSTALL documentationRich Felker2011-06-271-0/+10
|
* cleanup shared library build system to be more $HOME-local-install friendlyRich Felker2011-06-273-16/+21
| | | | | the path for the dynamic linker is now configurable, and failure to install the symlink for it will not stop the build.
* further fixup dlfcn.hRich Felker2011-06-271-4/+10
|
* match LSB/glibc constants for dynamic loaderRich Felker2011-06-271-4/+4
|
* fix stale pointer issue in dynamic linker with dlopenRich Felker2011-06-261-0/+1
|
* don't leave the lock held on dlopen failure..Rich Felker2011-06-261-2/+2
|
* add RTLD_DEFAULT supportRich Felker2011-06-261-1/+2
|
* in dlopen: don't use null pointerRich Felker2011-06-261-3/+3
| | | | deps can be null if a library has no dependencies (such as libc itself)
* fix resolving symbols in objects loaded in RTLD_LOCAL modeRich Felker2011-06-261-0/+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.
* experimental dlopen/dlsym and dynlink changes needed to support themRich Felker2011-06-261-8/+125
|
* type directives for x86_64 math asmRich Felker2011-06-262-0/+2
|
* error handling in dynamic linkingRich Felker2011-06-261-2/+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.
* fix useless use of potentially-uninitialized mode variable in sem_openRich Felker2011-06-261-1/+1
|
* eliminate OOB array hacks in mallocRich Felker2011-06-261-46/+45
|
* use .type directives for math asm (needed for dynamic linking to work)Rich Felker2011-06-2615-0/+26
|
* fix some symbol resolution issues in dynamic linkerRich Felker2011-06-253-4/+6
| | | | | 1. search was wrongly beginning with lib itself rather than dso head 2. inconsistent resolution of function pointers for functions in plt
* fix dynamic linker issue in musl-gcc wrapperRich Felker2011-06-251-1/+1
|
* wordexp cannot use we_offs unless WRDE_DOOFFS flag is setRich Felker2011-06-251-1/+2
| | | | | | previously, a potentially-indeterminate value from we_offs was being used, resulting in wrong we_wordc and subsequent crashes in the caller.
* XSI search.h API implementation by Szabolcs NagyRich Felker2011-06-256-4/+392
|
* handle library paths better (ignore empty path components, etc.)Rich Felker2011-06-251-3/+5
|
* move all limits that don't vary out of bits/limits.h, into main limits.hRich Felker2011-06-253-53/+24
|
* fix possible (questionable) strict aliasing violations and ptr arithRich Felker2011-06-251-3/+3
|
* const correctness in mq_notifyRich Felker2011-06-251-1/+1
| | | | why did gcc allow this invalid assignment to compile in the first place?
* proper path searching for dynamic linkerRich Felker2011-06-253-14/+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.
* optimize opendir using O_CLOEXECRich Felker2011-06-251-2/+1
