| 2011-06-30 | add and consolidate nasty stdio_ext junk•••hopefully this resolves the rest of the issues with hideously
nonportable hacks in programs that use gnulib.
| Rich Felker | 4 | -17/+84 |
| 2011-06-30 | implement the nonstandard GNU function fpurge•••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.
| Rich Felker | 2 | -0/+12 |
| 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•••these interfaces are required to be thread-safe even though they are
not state-free. the random number sequence is shared across all
threads.
| Rich Felker | 1 | -7/+28 |
| 2011-06-29 | work around linux bug in mprotect•••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 0.7.11 | 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•••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.
| Rich Felker | 1 | -1/+1 |
| 2011-06-28 | make dynamic linker relocate the main program image last, after all libs•••prior to this change, copy relocations for initialized pointer
variables would not reflect the relocated contents of the pointer.
| Rich Felker | 1 | -0/+1 |
| 2011-06-28 | fix a few bugs from last dynamic linking build system commit•••some cruft was left and DESTDIR was not being used correctly.
| Rich Felker | 1 | -2/+2 |
| 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•••the path for the dynamic linker is now configurable, and failure to
install the symlink for it will not stop the build.
| Rich Felker | 3 | -16/+21 |
| 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•••deps can be null if a library has no dependencies (such as libc itself)
| Rich Felker | 1 | -3/+3 |
| 2011-06-26 | fix resolving symbols in objects loaded in RTLD_LOCAL mode•••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.
| Rich Felker | 1 | -0/+11 |
| 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•••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.
| Rich Felker | 1 | -2/+19 |
| 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•••1. search was wrongly beginning with lib itself rather than dso head
2. inconsistent resolution of function pointers for functions in plt
| Rich Felker | 3 | -4/+6 |
| 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•••previously, a potentially-indeterminate value from we_offs was being
used, resulting in wrong we_wordc and subsequent crashes in the
caller.
| Rich Felker | 1 | -1/+2 |
| 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•••why did gcc allow this invalid assignment to compile in the first place?
| Rich Felker | 1 | -1/+1 |
| 2011-06-25 | proper path searching for dynamic linker•••first, use $LD_LIBRARY_PATH unless suid. if that fails, read path from
/etc/ld-musl-$ARCH.path and fallback to a builtin default.
| Rich Felker | 3 | -14/+42 |
| 2011-06-25 | optimize opendir using O_CLOEXEC | Rich Felker | 1 | -2/+1 |
| 2011-06-25 | discard dso descriptors after performing relocations•••eventually (once dlopen exists) this behavior will be conditional on
dlopen/dlsym not being reachable.
| Rich Felker | 1 | -0/+12 |
| 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•••the linker script caused a bogus DT_NEEDED entry
| Rich Felker | 1 | -2/+2 |
| 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)•••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.

| 2011-06-23 | initial commit of prng implementation by Szabolcs Nagy | Rich Felker | 3 | -12/+111 |
| 2011-06-19 | make ldso asm more uniform with rest of codebase (no unnecessary suffixes) | Rich Felker | 1 | -12/+12 |
| 2011-06-19 | x86_64: ensure that dtor pointer passed to app is 0 so it won't be used•••leaving it uninitialized caused unpredictable crashes or worse due to
calling an indeterminate function pointer.
| Rich Felker | 1 | -0/+1 |
| 2011-06-18 | dynamic linker 64bit fix: hash table entries are always 32bit | Rich Felker | 1 | -2/+2 |
| 2011-06-18 | experimental dynamic linker!•••some notes:
- library search path is hard coded
- x86_64 code is untested and may not work
- dlopen/dlsym is not yet implemented
- relocations in read-only memory won't work
| Rich Felker | 5 | -0/+466 |
