* | zero precision with zero value should not inhibit prefix/width printing | Rich Felker | 2011-07-04 | 1 | -1/+4 | |
| | ||||||
* | printf("%#x",0) should print 0 not 0x0 | Rich Felker | 2011-07-04 | 1 | -1/+1 | |
| | ||||||
* | iconv was not returning -1 on most failure | Rich Felker | 2011-07-03 | 1 | -0/+2 | |
| | | | | | this broke most uses of iconv in real-world programs, especially glib's iconv wrappers. | |||||
* | fix dlopen UB due to longjmp/volatile rules violation | Rich Felker | 2011-07-01 | 1 | -1/+1 | |

* | res_search symbol, aliased to res_query for now (better than nothing) | Rich Felker | 2011-06-30 | 1 | -0/+3 | |
| | ||||||
* | simple rpath support (no token expansion yet) for dynamic linker | Rich Felker | 2011-06-30 | 1 | -2/+8 | |

* | fix error in previous ld80 fpclassify commit | Rich Felker | 2011-06-30 | 1 | -1/+1 | |
| | ||||||
* | catch invalid ld80 bit patterns and treat them as nan | Rich Felker | 2011-06-30 | 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... | |||||
* | fix logic in __fwriting | Rich Felker | 2011-06-30 | 1 | -1/+1 | |
| | ||||||
* | add and consolidate nasty stdio_ext junk | Rich Felker | 2011-06-30 | 3 | -17/+57 | |
| | | | | | hopefully this resolves the rest of the issues with hideously nonportable hacks in programs that use gnulib. | |||||
* | implement the nonstandard GNU function fpurge | Rich Felker | 2011-06-30 | 1 | -0/+11 | |
| | | | | | | 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 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 | Rich Felker | 2011-06-29 | 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. | |||||
* | work around linux bug in mprotect | Rich Felker | 2011-06-29 | 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. | |||||
* | 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 | Rich Felker | 2011-06-28 | 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. | |||||
* | make dynamic linker relocate the main program image last, after all libs | Rich Felker | 2011-06-28 | 1 | -0/+1 | |
| | | | | | prior to this change, copy relocations for initialized pointer variables would not reflect the relocated contents of the pointer. | |||||
* | 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 | Rich Felker | 2011-06-26 | 1 | -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 mode | Rich Felker | 2011-06-26 | 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. | |||||
* | 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 | Rich Felker | 2011-06-26 | 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. | |||||
* | 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 | Rich Felker | 2011-06-25 | 1 | -4/+4 | |
| | | | | | 1. search was wrongly beginning with lib itself rather than dso head 2. inconsistent resolution of function pointers for functions in plt | |||||
* | wordexp cannot use we_offs unless WRDE_DOOFFS flag is set | Rich Felker | 2011-06-25 | 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. | |||||
* | 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 | Rich Felker | 2011-06-25 | 1 | -1/+1 | |
| | | | | why did gcc allow this invalid assignment to compile in the first place? | |||||
* | proper path searching for dynamic linker | Rich Felker | 2011-06-25 | 1 | -14/+38 | |
| | | | | | 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_CLOEXEC | Rich Felker | 2011-06-25 | 1 | -2/+1 | |
| | ||||||
* | discard dso descriptors after performing relocations | Rich Felker | 2011-06-25 | 1 | -0/+12 | |
| | | | | | eventually (once dlopen exists) this behavior will be conditional on dlopen/dlsym not being reachable. | |||||
* | 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) | Rich Felker | 2011-06-23 | 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. | |||||
* | 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 | Rich Felker | 2011-06-19 | 1 | -0/+1 | |
| | | | | | leaving it uninitialized caused unpredictable crashes or worse due to calling an indeterminate function pointer. | |||||
* | dynamic linker 64bit fix: hash table entries are always 32bit | Rich Felker | 2011-06-18 | 1 | -2/+2 | |
| | ||||||
* | experimental dynamic linker! | Rich Felker | 2011-06-18 | 3 | -0/+412 | |
| | | | | | | | | 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 | |||||
* | 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) | Rich Felker | 2011-06-14 | 20 | -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. |
