| * | fix logic in __fwriting | Rich Felker | 2011-06-30 | 1 | -1/+1 |
| * | 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 | 2011-06-30 | 3 | -17/+57 |
| * | 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 | 2011-06-30 | 1 | -0/+11 |
| * | fix buffer overrun in getgrent code when there are no group members | Rich Felker | 2011-06-30 | 1 | -4/+8 |
| * | posix_memalign should fail if size is not a multiple of sizeof(void *) | Rich Felker | 2011-06-29 | 1 | -1/+1 |
| * | 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 | 2011-06-29 | 1 | -7/+28 |
| * | 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.
| Rich Felker | 2011-06-29 | 1 | -1/+5 |
| * | textrel support, cheap and ugly | Rich Felker | 2011-06-29 | 1 | -0/+5 |
| * | reclaim the memory wasted by dynamic linking for use by malloc | Rich Felker | 2011-06-28 | 1 | -0/+39 |
| * | use type directives for fenv asm functions | Rich Felker | 2011-06-28 | 2 | -0/+14 |
| * | 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 | 2011-06-28 | 1 | -1/+1 |
| * | 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 | 2011-06-28 | 1 | -0/+1 |
| * | fix stale pointer issue in dynamic linker with dlopen | Rich Felker | 2011-06-26 | 1 | -0/+1 |
| * | don't leave the lock held on dlopen failure.. | Rich Felker | 2011-06-26 | 1 | -2/+2 |
| * | add RTLD_DEFAULT support | Rich Felker | 2011-06-26 | 1 | -1/+2 |
| * | in dlopen: don't use null pointer•••deps can be null if a library has no dependencies (such as libc itself)
| Rich Felker | 2011-06-26 | 1 | -3/+3 |
| * | 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 | 2011-06-26 | 1 | -0/+11 |
| * | experimental dlopen/dlsym and dynlink changes needed to support them | Rich Felker | 2011-06-26 | 1 | -8/+125 |
| * | type directives for x86_64 math asm | Rich Felker | 2011-06-26 | 2 | -0/+2 |
| * | 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 | 2011-06-26 | 1 | -2/+19 |
| * | fix useless use of potentially-uninitialized mode variable in sem_open | Rich Felker | 2011-06-26 | 1 | -1/+1 |
| * | eliminate OOB array hacks in malloc | Rich Felker | 2011-06-26 | 1 | -46/+45 |
| * | use .type directives for math asm (needed for dynamic linking to work) | Rich Felker | 2011-06-26 | 15 | -0/+26 |
| * | 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 | 2011-06-25 | 1 | -4/+4 |
| * | 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 | 2011-06-25 | 1 | -1/+2 |
| * | XSI search.h API implementation by Szabolcs Nagy | Rich Felker | 2011-06-25 | 4 | -0/+352 |
| * | handle library paths better (ignore empty path components, etc.) | Rich Felker | 2011-06-25 | 1 | -3/+5 |
| * | fix possible (questionable) strict aliasing violations and ptr arith | Rich Felker | 2011-06-25 | 1 | -3/+3 |
| * | const correctness in mq_notify•••why did gcc allow this invalid assignment to compile in the first place?
| Rich Felker | 2011-06-25 | 1 | -1/+1 |
| * | 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 | 2011-06-25 | 1 | -14/+38 |
| * | optimize opendir using O_CLOEXEC | Rich Felker | 2011-06-25 | 1 | -2/+1 |
| * | discard dso descriptors after performing relocations•••eventually (once dlopen exists) this behavior will be conditional on
dlopen/dlsym not being reachable.
| Rich Felker | 2011-06-25 | 1 | -0/+12 |
| * | keep track of which dsos have been relocated | Rich Felker | 2011-06-25 | 1 | -0/+1 |
| * | 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.
| Rich Felker | 2011-06-23 | 1 | -0/+6 |
| * | initial commit of prng implementation by Szabolcs Nagy | Rich Felker | 2011-06-23 | 2 | -12/+107 |
| * | make ldso asm more uniform with rest of codebase (no unnecessary suffixes) | Rich Felker | 2011-06-19 | 1 | -12/+12 |
| * | 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 | 2011-06-19 | 1 | -0/+1 |
| * | dynamic linker 64bit fix: hash table entries are always 32bit | Rich Felker | 2011-06-18 | 1 | -2/+2 |
| * | 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 | 2011-06-18 | 3 | -0/+412 |
| * | fix memory leak on failure in realpath | Rich Felker | 2011-06-18 | 1 | -4/+4 |
| * | duplicate re_nsub in LSB/glibc ABI compatible location | Rich Felker | 2011-06-16 | 1 | -1/+1 |
| * | restore use of .type in asm, but use modern @function (vs %function)•••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.
| Rich Felker | 2011-06-14 | 20 | -0/+29 |
| * | fix race condition in pthread_kill•••if thread id was reused by the kernel between the time pthread_kill
read it from the userspace pthread_t object and the time of the tgkill
syscall, a signal could be sent to the wrong thread. the tgkill
syscall was supposed to prevent this race (versus the old tkill
syscall) but it can't; it can only help in the case where the tid is
reused in a different process, but not when the tid is reused in the
same process.
the only solution i can see is an extra lock to prevent threads from
exiting while another thread is trying to pthread_kill them. it should
be very very cheap in the non-contended case.
| Rich Felker | 2011-06-14 | 3 | -1/+8 |
| * | run dtors before taking the exit-lock in pthread exit•••previously a long-running dtor could cause pthread_detach to block.
| Rich Felker | 2011-06-14 | 1 | -2/+2 |
| * | minor locking optimizations | Rich Felker | 2011-06-14 | 2 | -2/+2 |
| * | avoid 64bit warnings when using pointers as entropy for temp names | Rich Felker | 2011-06-13 | 2 | -2/+4 |
| * | fix sigset macro for 64-bit systems (<< was overflowing due to wrong type) | Rich Felker | 2011-06-13 | 1 | -1/+1 |
| * | remove all .size and .type directives for functions from the asm•••these are useless and have caused problems for users trying to build
with non-gnu tools like tcc's assembler.
| Rich Felker | 2011-06-13 | 18 | -52/+0 |
| * | remove old useless timezone.s file (unused) | Rich Felker | 2011-06-13 | 1 | -27/+0 |
| * | fix wrong type for wcsrchr argument 2 | Rich Felker | 2011-06-13 | 1 | -1/+1 |
