12 years agoCorrect a bug when remapping textrel segments on nommu
Alan Davis [Thu, 26 May 2011 16:15:06 +0000 (18:15 +0200)]
Correct a bug when remapping textrel segments on nommu

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.

libubacktrace: generic implementation based dwarf

Use the initial implementation for SH4 based on dwarf for all archs.
Indeed there are not obvious reason for which it should not work in general.

MIPS LDSO: pass sym_ref parameter to _dl_find_hash() to support PROTECTED symbols

_dl_find_hash() relies on sym_ref parameter to check if the looked-up symbol
is protected. The code fixes a case when _dl_perform_mips_global_got_relocations()
was calling _dl_find_hash() without providing sym_ref parameter.
The bug was causing hangs if a library exporting non-protected symbol was earlier in
link order than library with the same symbol declared as protected.
