* [BZ #15022] Correct global-scope dlopen issues in static executables.Maciej W. Rozycki2013-06-283-31/+46
| | | | | | | | This change creates a link map in static executables to serve as the global search list for dlopen. It fixes a problem with the inability to access the global symbol object and a crash on an attempt to map a DSO into the global scope. Some code that has become dead after the addition of this link map is removed too and test cases are provided.

* Avoid crashing in LD_DEBUG when program name is unavailableSiddhesh Poyarekar2013-05-2914-49/+92
| | | | | | | | | Resolves: #15465 The program name may be unavailable if the user application tampers with argc and argv[]. Some parts of the dynamic linker caters for this while others don't, so this patch consolidates the check and fallback into a single macro and updates all users.
* Update comments in ldconfig.c and dl-hwcaps.c.Carlos O'Donell2013-05-222-8/+10
| | | | | | | | | | | | | | | | | In dl-hwcaps.c the comment read that rounding was done to ElfW(Addr), but it's actually rounded to ElfW(Word). In ldconfig.c we make each comment a sentence and mention that the "tls" pseudo-hwcap is just for legacy installations where TLS was optional. --- 2013-05-22 Carlos O'Donell <carlos@redhat.com> * elf/ldconfig.c (is_hwcap_platform): Make comments full setences. (main): Mention "tls" pseudo-hwcap is legacy. * elf/dl-hwcaps.c (_dl_important_hwcaps): Correct rounding comment.
* Add #include <stdint.h> for uint[32|64]_t usage (except installed headers).Ryan S. Arnold2013-05-167-1/+7

* Add comments to vDSO hwcap loading process.Carlos O'Donell2013-05-142-1/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Loading of the vDSO pseudo-hwcap from the type 2 GNU note is a rather arcane and poorly documented process. Given that I had a chance to review this code today I thought I would add all of the things I had to lookup to verify the validity of the process. With a single .note.GNU the vDSO can register up to 64 flags, though in practice you are limited to 64 - _DL_FIRST_EXTRA bits which on x86 is 12 bits. The only use of this that I know of is in the Xen support in Linux where they use the 1st bit to indicate "nosegneg". I see "We use bit 1 to avoid bugs in some versions of glibc when bit 0 is used; the choice is otherwise arbitrary.", but no reference to a glibc bug anywhere. The code as-is should support bit zero, so we still have that free for future use. The kernel, glibc, and ld.so.cache must coordinate to ensure that bit values don't go too high and are used consistently. --- 2013-05-13 Carlos O'Donell <carlos@redhat.com> * elf/dl-hwcaps.c (_dl_important_hwcaps): Comment vDSO hwcap loading. * elf/ldconfig.c (is_hwcap_platform): Comment each hwcap check. (main): Comment "tls" pseudo-hwcap.
* Use *stat64 instead of *stat in installed programsFlorian Weimer2013-05-101-2/+2
| | | | | This ensures reliable operation on file systems with inode numbers which do not fit into 32 bits.
* Add more comments to dlclose() algorithm.Carlos O'Donell2013-05-091-0/+6
| | | | | | | | | | | | | | The algorithm for scanning dependencies upon dlclose is less than immediately obvious. This patch adds two bits of comments that explain why you start the dependency search at l_initfini[1], and why you need to restart the search. --- 2013-05-09 Carlos O'Donell <carlos@redhat.com> * elf/dl-close.c (_dl_close_worker): Add comments.

* dl_open_worker: Memset all of seen array.Carlos O'Donell2013-04-061-1/+1
| | | | | | | | | | | | | The seen array was doubled in size recently, but the memset to clear the array was not adjusted. We adjust the memset to always be correct regardless of the size of seen. --- 2013-04-06 Carlos O'Donell <carlos@redhat.com> [BZ #15309] * elf/dl-open.c (dl_open_worker): memset all of seen array.

* Add more comments to _dl_load_cache_lookup().Carlos O'Donell2013-02-081-2/+3
| | | | | | Calling _dl_load_cache_lookup will load the cache if not already. If loading the cache fails no more attempts will be made to load the cache.
* ARM: Support loading unmarked objects from cache.Carlos O'Donell2013-02-081-0/+4
| | | | | | | | | | | | ARM now supports loading unmarked objects from the dynamic loader cache. Unmarked objects can be used with the hard-float or soft-float ABI. We must support loading unmarked objects during the transition period from a binutils that does not mark objects to one that does mark them with the correct ELF flags.
