* const correctness on function pointerRich Felker2011-07-241-1/+1
|
* simplify dynamic linker startupRich Felker2011-07-241-23/+17
| | | | | | instead of creating temp dso objects on the stack and moving them to the heap if dlopen/dlsym are used, use static objects to begin with, and just donate them to malloc if we no longer need them.
* some preliminaries for vdso clock supportRich Felker2011-07-233-7/+35
| | | | | | | | these changes also make it so clock_gettime(CLOCK_REALTIME, &ts) works even on pre-2.6 kernels, emulated via the gettimeofday syscall. there is no cost for the fallback check, as it falls under the error case that already must be checked for storing the error code in errno, but which would normally be hidden inside __syscall_ret.
* check for fd exhaustion in forkptyRich Felker2011-07-221-2/+15
| | | | | | | we cannot report failure after forking, so the idea is to ensure prior to fork that fd 0,1,2 exist. this will prevent dup2 from possibly hitting a resource limit and failing in the child process. fcntl rather than dup2 is used prior to forking to avoid race conditions.
* incorrect check for open failure in openpty functionRich Felker2011-07-221-1/+1
| | | | -1, not 0, indicates failure
* fix errno value when fdopendir is given an invalid file descriptorRich Felker2011-07-211-1/+4
| | | | this resolves an issue reported by Vasiliy Kulikov
* ensure in fork that child gets its own new robust mutex listRich Felker2011-07-161-0/+1
|
* fix logic error in freadRich Felker2011-07-161-6/+1
| | | | | | | | fread was calling f->read without checking that the file was in reading mode. this could: 1. crash, if f->read was a null pointer 2. cause unwanted blocking on a terminal already at eof 3. allow reading on a write-only file
* fix various bugs in new integer parser frameworkRich Felker2011-07-145-10/+15
| | | | | | | | | | 1. my interpretation of subject sequence definition was wrong. adjust parser to conform to the standard. 2. some code for handling tail overflow case was missing (forgot to finish writing it). 3. typo (= instead of ==) caused ERANGE to wrongly behave like EINVAL
* fix wcsto[iu]max with high charactersRich Felker2011-07-142-4/+2
| | | | | | | | stopping without letting the parser see a stop character prevented getting a result. so treat all high chars as the null character and pass them into the parser. also eliminated ugly tmp var using compound literals.
* new restartable integer parsing framework.Rich Felker2011-07-146-156/+197
| | | | | | | | | this fixes a number of bugs in integer parsing due to lazy haphazard wrapping, as well as some misinterpretations of the standard. the new parser is able to work character-at-a-time or on whole strings, making it easy to support the wide functions without unbounded space for conversion. it will also be possible to update scanf to use the new parser.
* gb18030 support in iconv (only from, not to)Rich Felker2011-07-122-2/+1887
| | | | | also support (and restrict to subsets) older chinese sets, and explicitly refuse to convert to cjk (since there's no code for it yet)
* "implement" getnetbyaddr and getnetbynameRich Felker2011-07-121-0/+12
| | | | | these are useless legacy functions but some old software contains cruft that expects them to exist...
* legacy japanese charset support in iconv (only from, not to)Rich Felker2011-07-122-0/+597
|
* simplify iconv and support more legacy codepagesRich Felker2011-07-123-352/+331
|
* printf: "if a precision is specified, the '0' flag shall be ignored."Rich Felker2011-07-041-1/+1
|
* 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.
* 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
|
* 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 Felker2011-06-303-17/+57
| | | | | hopefully this resolves the rest of the issues with hideously nonportable hacks in programs that use gnulib.
* implement the nonstandard GNU function fpurgeRich Felker2011-06-301-0/+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 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
|
* 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
|
* 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 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 Felker2011-06-251-4/+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 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 Felker2011-06-254-0/+352
