| | | | | | | | | | | | | | | This is based on Ulrich Drepper's implementation in GLIBC, but hacked up to work in uClibc. The differences from the GLIBC version are as follows: - b64_from_24bit() has been converted into a macro - Usage of GLIBC-isms (such as libc_freeres_ptr) have been removed It is enabled by the UCLIBC_HAS_SHA256_CRYPT_IMPL configuration symbol.

* libc/x86: fix stack unwinding and backtrace informationTimo Teräs2011-12-233-75/+28
| | | | | | | | | | | | | | | | | | | | | | | When compiled without framepointer, the DWARF-2 CFI data is required for proper stack unwinding. This patch adds the CFI information to: * syscalls (so we get proper backtrace even for release builds) the ebx hack was removed as it would complicate the CFI generation * new thread stub function (so the backtrace is clean for user created threads) Also pads the signal return trampolines separate from other functions. If CFI info was found for signal return code (which seems to happen if it's located right next a valid function), it will not be recognized as signal trampoline (gcc unwinder and gdb check first CFI info, and only if it does not exists it compares the exact opcode sequence to see if we are at signal return code block). This fixes a real crash if thread is cancelled and the cancellation handler fails to detect the signal return frame.

Things might go very wrong because stdint.h has conditional defines and if stdlib.h is included before #define's for stdint.h we end up missing things and breaking builds (e.g. openjdk).

* resolv: fix resolver to return TRY_AGAIN on timeoutTimo Teräs2011-12-231-46/+49
| | | | | | | | | | | | | | | | | | | | | This fixes the internal __dns_lookup to get a h_errno pointer so it works nicely with the _r variants. Additionally the function is modified to permanent error if the static buffer lengths are not enough. And finally it fixed to return TRY_AGAIN if the nameservers timeout. res_search is fixed to continue searching if we receive TRY_AGAIN. It could be a problem with the specific search domain's server and not necessarily a problem in the recursive resolver we are querying. For same reason, it does not make sense to differentiate timeout or SERVFAIL error reply. The biggest issue this fixes is that we now properly set h_errno to TRY_AGAIN if upstream nameserver(s) timed out. Previously we would have returned NETDB_INTERNAL.

* resolv: res_query for CNAMEsTimo Teräs2011-12-231-5/+3
| | | | | | | | | | | | | From: http://lists.busybox.net/pipermail/uclibc/2009-June/042583.html I had postfix failing for domains with MX->CNAME->A chain. In glibc it works. I tracked it to be a problem in uclibc res_query. It returns bogus data for CNAME entries, apparently intentionally, which is wrong. glibc return CNAME entries even for CNAME queries and most applications rely on this. So we should do the same in uclibc. Signed-off-by: Natanael Copa <ncopa@alpinelinux.org>

* Correct a bug when remapping textrel segments on nommuAlan Davis2011-05-271-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From: Alan Davis <adavis@ti.com> On C6X, when trying to execute a program that has a textrel DSO, it fails to load. The telltale line in the LD_DEBUG output is: _dl_get_ready_to_run:779: file=''; needed by './a.out' The corresponding DT_NEEDED entry has 'libc.so.0', but here the filename is empty. This is what is happening in _dl_elf_shared_library(): First, map all segments according to their permissions. Text gets initially mapped read-only. Then, parse the dynamic information. The dynamic table is in RW but some of the tags may point to RO. For example, DT_NEEDED points to a string in .dynstr which is in RO. These pointers get computed according to the loadmap from the original mapping. Then, in response to a DT_TEXTREL tag, the RO segment gets remapped, thereby invaliding anything that points to it, in particular certain dynamic tags such as DT_NEEDED. The following patch re-parses the dynamic info after the remapping so as to re-compute any invalid pointers.
