* libelf: Fix handling of (extended) phnum.Mark Wielaard2014-11-173-7/+24
| | | | | | | | If there is no e_phoff e_phnum cannot be trusted. Extended phnum can only be gotten if we have an actual section table and a shdr for section zero, Extended phnum can be too large to fit in the file (or a size_t). Signed-off-by: Mark Wielaard <[email protected]>
* gelf_getnote: Check padding overflow.Mark Wielaard2014-11-162-2/+11
| | | | | | | Since ELF notes need to be properly aligned they can include padding. Make sure the padding itself and the padding calculation doesn't overflow. Signed-off-by: Mark Wielaard <[email protected]>
* libelf: getdata check 64bit values correctly on 32bit arch.Mark Wielaard2014-11-162-3/+8
| | | | | | | | On 32bit arches size_t is too small to do size and overflow checks of 64bit ELF files. Use the actual Elf64 types to make sure checks on 64bit ELF files are done correctly on 32bit arches. Signed-off-by: Mark Wielaard <[email protected]>

* libelf: Use mempcpy not __mempcpy.Mark Wielaard2014-11-132-2/+6
| | | | | | | We were using mempcpy everywhere else, only __libelf_next_arhdr_wrlock used __mempcpy. Signed-off-by: Mark Wielaard <[email protected]>

* elf_begin sets elf_errno for cases that the file is completely unreadablePetr Machata2014-09-112-3/+11
| | | | | | | | | | | | | | - The problem this is trying to solve can be seen for example thus: $ eu-readelf -a / eu-readelf: failed reading '/': (null) With the fix we see a proper error number and get a reasonable error message: $ eu-readelf -a / eu-readelf: failed reading '/': invalid file descriptor Signed-off-by: Petr Machata <[email protected]>
* Update elf.h from glibc.Mark Wielaard2014-07-042-1/+33
| | | | | | | Includes new bits needed for ppc64le ELFv2 abi. https://bugzilla.redhat.com/show_bug.cgi?id=1110249 Signed-off-by: Mark Wielaard <[email protected]>
* Remove mudflap build option.Mark Wielaard2014-04-184-14/+8
| | | | | | | | | The --enable-mudflap configure build has been broken for 2 years without anybody apparently noticing. GCC 4.9 removed mudflap support. Before release we now run make distcheck with valgrind support. Removal of the mudflap configure option simplifies the build a little. Signed-off-by: Mark Wielaard <[email protected]>

* libelf: Only memcpy ehdr back when not already directly mmapped.Mark Wielaard2013-11-112-1/+6
| | | | | | | | | | When the elf file is mmapped ehdr can still point to ehdr_mem if the address is unaligned. In such cases we do need to memcpy the ehdr back to the file. We shouldn't when ehdr already comes directly from the mmapped file, because that would cause an memcpy call with overlapping addresses (ehdr being copied directly over itself).

* libelf: Write all section headers if elf flags contains ELF_F_DIRTY.Mark Wielaard2013-11-052-2/+9
| | | | | | | | | When ehdr e_shoff changes, elf flags is set dirty. This indicates that the section header moved because sections were added/removed or changed in size. Reported-by: Jiri Slaby <[email protected]> Signed-off-by: Mark Wielaard <[email protected]>
* Check for prefixed ar, readelf, and nmMichael Forney2013-11-052-1/+5
| | | | | | | | Sometimes with cross-compile toolchains, the tools are prefixed with the target arch. Using AC_CHECK_TOOL looks for tools named like this. Signed-off-by: Michael Forney <[email protected]> Signed-off-by: Mark Wielaard <[email protected]>

* elf32_offscn.c: Do not match SHT_NOBITS sections at OFFSET.Mark Wielaard2012-04-022-1/+7
| | | | | | readelf -d doesn't work if a SHT_NOBITS section is right before the actual .dynamic section at the same offset. elflint also fails on such binaries. So skip SHT_NOBITS sections at the same offset in [g]elf[32|64]_offscn().

| | | | | | | | The gelf_update_[eps]hdr functions didn't implicitly mark the data structures as modified. This has always been the case and programs should set the bit but it is somewhat inconsistent since other update functions implicitly set the bit. Do it in these three cases, too.

* Fix fill_mmap for sections past the section headersLubomir Rintel2010-01-042-2/+10
| | | | | | | | | | If fill_mmap() was run for a section that's past the shdr_end, but does not immediately follow the section headers the fill start would be determined incorrectly as shdr_end, which would wipe off contents of sections between shdr_end and current one. Issue was reported and triaged by Hugo Mildenberger, Graham Murray and Peter Alfredsen. (http://bugs.gentoo.org/show_bug.cgi?id=288977)
