2011-07-27ldso/mips: dlsym() incorrectly matches undefined symbolsKevin Cernekee
check_match() relies on checking for (sym->st_value == 0) to see if the symbol is undefined. This works reasonably well on most architectures, such as ARM or i386: $ readelf -s /lib32/libcap.so.2 | grep -E "\<malloc\>" 17: 00000000 0 FUNC GLOBAL DEFAULT UND malloc@GLIBC_2.0 (2) However, on MIPS, libbfd puts nonzero data in the st_value field to facilitate resetting the symbol's GOT entry if the library that defines the symbol gets unloaded: $ mipsel-linux-readelf -s libfoo.so | grep -E "\<malloc\>" 74: 00003140 0 FUNC GLOBAL DEFAULT UND malloc This can cause check_match to report a false positive when examining the external symbol reference. Consequently dlsym() will return a bad pointer to the caller. Use the special MIPS logic from glibc-ports-2.13 to avoid this situation.

The net effect is that when running with "LD_DEBUG=reloc", ldso itself crashes before the program even starts. This is caused by _dl_dprintf() dereferencing an unadjusted string pointer such as 0xe570. This patch enables the missing relocations and allows LD_DEBUG to work as designed.

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.

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.

2011-04-11Support dynamic assignment of DSBT_INDEXBernd Schmidt
For DSBT targets (C6X only at this point), we'd like to support the case where the user did not specify --dsbt-index at link time when building a shared library. The dynamic linker can still assign an index at runtime and fix up the DSBT_INDEX relocs, at the cost of startup time and memory space. Signed-off-by: Bernd Schmidt <bernds@codesourcery.com>
2011-04-11Fix nommu handling of DT_TEXTRELBernd Schmidt
We have a problem with DT_TEXTREL shared libraries on nommu machines. The dynamic linker's strategy is to map the text segment read-only first, then look for DT_TEXTREL, and use mprotect to change protections if necessary. This fails on nommu, since a nommu kernel can decide to share the memory for private read-only file mappings, and mprotect doesn't (can't) do anything about this sharing. Existing nommu targets apparently have no need for this, but on C6X, we may need to assign library indices at run-time if no --dsbt-index option was passed to the linker at build time. Hence, the following patch, which instead of using mprotect, redoes the mapping with PF_W set. Signed-off-by: Bernd Schmidt <bernds@codesourcery.com>

2011-02-21ldso: fix fdpic buildsMike Frysinger
Commit 33cb7f0b4 tried to add a small optimization for skipping unnecessary .dynamic adjustments, but did so by referencing an opaque type. While this works for non-fdpic targets (since the type can be cast to an integer), it falls apart for fdpic targets where the type is actually a structure. Since FDPIC can't support this optimization without walking a series of linked structures, just skip it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2011-01-20Add protected symbols support for all architecturesSalvatore Cro
Protected symbols are global symbols for which interposition is not allowed. We manage them in generic _dl_lookup_hash function. To handle protected symbols we need to get a reference to the module that defines the symbol itself. So we pass a new parameter 'struct symbol_ref' to the __dl_lookup_hash that is defined as below: struct symbol_ref { const ElfW(Sym) *sym; struct elf_resolve *tpnt; }; The tpnt field is used as an ouput parameter and refers to the module which defines the protected symbol. Further it can be used as output parameter for TLS relocations and FDPIC case. The sym field is instead used as an input parameter to detect the visibility of the symbol we are looking-up. In this way we get rid of different signatures for _dl_lookup_hash, allowing to remove the _dl_find_hash wrapper. This new structure is also suitable for prelink integration.
