* Trust AC_SYS_LARGEFILE to provide large file supportJosh Stone2015-10-091-6/+6
| | | | | | | | | | | | | | | AC_SYS_LARGEFILE defines _FILE_OFFSET_BITS in config.h if needed for LFS, and this automatically maps things like open to open64. But quite a few places used explicit 64-bit names, which won't work on platforms like FreeBSD where off_t is always 64-bit and there are no foo64 names. It's better to just trust that AC_SYS_LARGEFILE is doing it correctly. But we can verify this too, as some file could easily forget to include config.h. The new tests/run-lfs-symbols.sh checks all build targets against lfs-symbols (taken from lintian) to make sure everything was implicitly mapped to 64-bit variants when _FILE_OFFSET_BITS is set.

* strip: Only sanity check symbols to not discarded sections for debug file.Mark Wielaard2015-10-091-3/+5
| | | | | | | | | | | | | | We can only sanity check the symbols to discarded sections when creating a debug file. Otherwise we won't keep track of debug_data. This can trigger erroneously when there are relocation symbols in the symtab for a .debug section but we are not putting those symbols in a separate .debug file. Adjust run-strip-test.sh to always run in-place strip size check even for ET_REL files. Before this fix the sanity check would trigger for some ET_REL files because they contained such relocation symbols to .debug sections (but debug_data would be NULL because -f wasn't used).

* Handle merged strtab/shstrtab string tables in strip and unstrip.Mark Wielaard2015-10-051-6/+9
| | | | | | | | | | | | | | | | | | | | | ELF files can share the section header string table (e_shstrndx) with the symtab .strtab section. That might in some cases save a bit of space since symbols and sections might share some (sub)strings. To handle that eu-strip just needs to not unconditionally remove the .shstrtab section (it will be properly marked as used/unused as needed). eu-unstrip needs to make sure the section names are added to the strtab if it decides to rewrite that section. Also makes sure that eu-strip won't move around a SHT_NOBITS section that has SHF_ALLOC set. Although it is allowed to move such sections around, there is no benefit. And some tools might expect no allocated section to move around, not even a nobits section. It also makes it harder to do "roundtripping" sanity checks that make sure splitting a file with eu-strip and then reconstructed with eu-unstrip produce the same ELF file (as is done in the new run-strip-strmerge.sh). Introduces a somewhat large test generator elfstrmerge.c that will hopefully turn into a more generic string table merger program. Signed-off-by: Mark Wielaard <[email protected]>
* Remove old-style function definitions.Mark Wielaard2015-09-231-2/+2

* strip: Just admit we don't support stripping ar archives for now.Mark Wielaard2015-06-101-2/+12
| | | | | | | | | | | | | We try to handle (in-place) stripping of ar archives, but since elf_clone doesn't really support cloning ar members and we don't handle reducing the size of the members, moving the offsets of other members. This causes crashes or writing garbage. Better to just admit that for now we don't support stripping archives. Call error when we see an ELF_K_AR file. https://bugzilla.redhat.com/show_bug.cgi?id=766156 https://lists.fedorahosted.org/pipermail/elfutils-devel/2009-August/000567.html Signed-off-by: Mark Wielaard <[email protected]>
* strip: Harden against bogus input files. Don't leak tmp debug file on error.Mark Wielaard2015-05-181-77/+191
| | | | | | | | | | There were various places where a bogus/unexpected input file would cause eu-strip to crash. Also on an unexpected error eu-strip would leak the temp debug file it was writing. https://bugzilla.redhat.com/show_bug.cgi?id=1170810#c34 Signed-off-by: Mark Wielaard <[email protected]>
* Always call gelf_fsize with EV_CURRENT as argument.Mark Wielaard2015-05-131-12/+7
| | | | | | | | | | Don't trust the elf version given by the file. It could be completely bogus. In which case gelf_fsize just returns zero. Which could cause divide by zero errors. https://bugzilla.redhat.com/show_bug.cgi?id=1170810#c34 Signed-off-by: Mark Wielaard <[email protected]>

* Fix two memory leaks in findtextrel and strip.Mark Wielaard2013-03-011-1/+6
| | | | | | | | | | | The findtextrel leak is real, when processing lots of files without text relocations the files and memory wouldn't be released. The strip leak is minor since it can only happen when using -f which only allows one file as argument. But it is nice to see valgrind say: "All heap blocks were freed -- no leaks are possible".

* Add aliases for elf_getshnum and elf_getshstrndx.Ulrich Drepper2009-06-131-2/+2
| | | | | | | | | | Sun in their implementation messed up the semantics of these functions. To get back to source code compatibility they asked for a solution. We simply add aliases for the two affected functions, named elf_getshdrnum and elf_getshdrstrndx. The semantics remains the same. Users of the old interfaces receive a warning for now. In future we might make it impossible to link programs which request the old interfaces (binary compatibility will of course be maintained).
