2011-05-27Correct a bug when remapping textrel segments on nommuAlan Davis
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.

Fix dladdr to correctly handle local function's address so backtrace_symbols print only the function address for these function, instead of showing the name of nearest one. Indeed the dladdr walk through the hash table to find the nearest symbol, that doesn't contain local symbols.
