* Also set r->r_map when unmapping the first object in a namespace.Gary Benson2012-08-171-1/+1
| | | | | | When unmapping the first object in a namespace, the runtime linker did not update the externally visible pointer. This resulted in debuggers seeing pointers to memory that had been freed.

* Fix invalid memory access in do_lookup_x.Andreas Schwab2012-06-224-18/+15
| | | | | | | | [BZ #13579] Do not free l_initfini and allow it to be reused on subsequent dl_open calls for the same library. This fixes the invalid memory access in do_lookup_x when the previously free'd l_initfini was accessed through l_searchlist when a library had been opened for the second time.

| | | | | | | | [BZ #13882] * elf/dl-deps.c (_dl_map_object_deps): Fix cycle detection. Use uint16_t for elements in the "seen" array to avoid char overflows. * elf/dl-fini.c (_dl_sort_fini): Likewise. * elf/dl-open.c (dl_open_worker): Likewise.
* Remove use of INTDEF/INTUSE in stdio-commonAndreas Schwab2012-06-012-8/+6

* Fix stack size and address inconsistency due to executable stackSiddhesh Poyarekar2012-05-261-1/+70
| | | | | | | | | | | | | | | When a stack is marked executable due to loading a DSO that requires an executable stack, the logic tends to leave out a portion of stack after the first frame, thus causing a difference in the value returned by pthread_getattr_np before and after the stack is marked executable. It ought to be possible to fix this by marking the rest of the stack as executable too, but in the interest of marking as less of the stack as executable as possible, the path this fix takes is to make pthread_getattr_np also look at the first frame as the underflow end of the stack and compute size and stack top accordingly. The above happens only for the main process stack. NPTL thread stacks are not affected by this change.

* Parse hexadecimal and octal strings correctlySiddhesh Poyarekar2012-04-251-7/+25
| | | | | | | | The current implementation of __strtoul_internal seems to only pretend to support hex and octal strings by detecting a preceding 0x or 0 and marking base as 8 or 16. When it comes to the actual processing of the string, it only considers numeric values within, thus breaking hex values that may have [a-f] in them. Fixed with this commit.

* Fix ld.so regression.David S. Miller2012-04-101-6/+8
| | | | | | [BZ #13967] * elf/dynamic-link.h (_ELF_DYNAMIC_DO_RELOC): Handle the case where the is a gap between DT_REL(A) and DT_JMPREL.
* New ld.so argument --inhibit-ldcache to disable ld.so.cache lookupSiddhesh Poyarekar2012-04-114-4/+17
| | | | | | | | | | | It may sometimes be desirable to make the dynamic linker only pick up libraries from the library path and rpath and not look at the ld.so.cache that ldconfig generates. An example of such a use case is the glibc testsuite where the dynamic linker must not be influenced by any external paths or caches. This change adds a new option --inhibit-ldcache that when used, tells the dynamic linker to not use ld.so.cache even if it is available.
