| 2011-06-29 | locking support for random() prng | Rich Felker | -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/+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 | -0/+5 | |
| 2011-06-28 | release notes for 0.7.11v0.7.11 | Rich Felker | -0/+22 | |
| 2011-06-28 | reclaim the memory wasted by dynamic linking for use by malloc | Rich Felker | -0/+39 | |
| 2011-06-28 | use type directives for fenv asm functions | Rich Felker | -0/+14 | |
| 2011-06-28 | use load address from elf header if possible | Rich Felker | -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 | -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 | -2/+2 | |
| some cruft was left and DESTDIR was not being used correctly. | ||||
| 2011-06-27 | minor updates to INSTALL documentation | Rich Felker | -0/+10 | |
| 2011-06-27 | cleanup shared library build system to be more $HOME-local-install friendly | Rich Felker | -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 | -4/+10 | |
| 2011-06-27 | match LSB/glibc constants for dynamic loader | Rich Felker | -4/+4 | |
| 2011-06-26 | fix stale pointer issue in dynamic linker with dlopen | Rich Felker | -0/+1 | |
| 2011-06-26 | don't leave the lock held on dlopen failure.. | Rich Felker | -2/+2 | |
| 2011-06-26 | add RTLD_DEFAULT support | Rich Felker | -1/+2 | |
| 2011-06-26 | in dlopen: don't use null pointer | Rich Felker | -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 | -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 | -8/+125 | |
| 2011-06-26 | type directives for x86_64 math asm | Rich Felker | -0/+2 | |
| 2011-06-26 | error handling in dynamic linking | Rich Felker | -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 | |
| 2011-06-26 | eliminate OOB array hacks in malloc | Rich Felker | -46/+45 | |
| 2011-06-26 | use .type directives for math asm (needed for dynamic linking to work) | Rich Felker | -0/+26 | |
| 2011-06-25 | fix some symbol resolution issues in dynamic linker | Rich Felker | -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 | |
| 2011-06-25 | wordexp cannot use we_offs unless WRDE_DOOFFS flag is set | Rich Felker | -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 | -4/+392 | |
| 2011-06-25 | handle library paths better (ignore empty path components, etc.) | Rich Felker | -3/+5 | |
| 2011-06-25 | move all limits that don't vary out of bits/limits.h, into main limits.h | Rich Felker | -53/+24 | |
| 2011-06-25 | fix possible (questionable) strict aliasing violations and ptr arith | Rich Felker | -3/+3 | |
| 2011-06-25 | const correctness in mq_notify | Rich Felker | -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 | -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 | -2/+1 | |
| 2011-06-25 | discard dso descriptors after performing relocations | Rich Felker | -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 | -0/+1 | |
| 2011-06-24 | use soname in ld-musl.so to prevent filename appearing in DT_NEEDEDs | Rich Felker | -1/+1 | |
| 2011-06-24 | use symlink rather than bogus linker script for libc.so | Rich Felker | -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 | -9/+20 | |
| 2011-06-23 | prepare support for LD_LIBRARY_PATH (checking suid/sgid safety) | Rich Felker | -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. | ||||
| 2011-06-23 | initial commit of prng implementation by Szabolcs Nagy | Rich Felker | -12/+111 | |
| 2011-06-19 | make ldso asm more uniform with rest of codebase (no unnecessary suffixes) | Rich Felker | -12/+12 | |
| 2011-06-19 | x86_64: ensure that dtor pointer passed to app is 0 so it won't be used | Rich Felker | -0/+1 | |
| leaving it uninitialized caused unpredictable crashes or worse due to calling an indeterminate function pointer. | ||||
| 2011-06-18 | dynamic linker 64bit fix: hash table entries are always 32bit | Rich Felker | -2/+2 | |
| 2011-06-18 | experimental dynamic linker! | Rich Felker | -0/+466 | |
| 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 | ||||
| 2011-06-18 | fix memory leak on failure in realpath | Rich Felker | -4/+4 | |
| 2011-06-18 | copy-paste error in prctl.h | Rich Felker | -1/+1 | |
| 2011-06-16 | fix some struct padding to match LSB/glibc ABI where it may be helpful | Rich Felker | -2/+5 | |
| 2011-06-16 | duplicate re_nsub in LSB/glibc ABI compatible location | Rich Felker | -2/+3 | |
| 2011-06-14 | restore use of .type in asm, but use modern @function (vs %function) | Rich Felker | -0/+29 | |
| this seems to be necessary to make the linker accept the functions in a shared library (perhaps to generate PLT entries?) strictly speaking libc-internal asm should not need it. i might clean that up later. | ||||
