* Merge branch 'master' into portableMark Wielaard2015-06-1015-355/+1016
|\ | | | | | | Fixup futimens issues.
| * addr2line: Fix memory leak in print_dwarf_function.Mark Wielaard2015-06-102-5/+15
| | | | | | | | | | | | Always free the scopes returned by dwarf_getscopes () when done. Signed-off-by: Mark Wielaard <[email protected]>
| * strip: Just admit we don't support stripping ar archives for now.Mark Wielaard2015-06-102-2/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | 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]>
| * elfcmp: Don't call memcmp with possible NULL d_buf.Mark Wielaard2015-06-052-1/+6
| | | | | | | | | | | | When d_size is zero d_buf might be NULL. Signed-off-by: Mark Wielaard <[email protected]>
| * config: Add -Wstack-usage=262144 (256K) warning check.Mark Wielaard2015-05-272-0/+19
| | | | | | | | | | | | | | | | All library code now builds with this warning and -Werror enabled. Add exceptions for most of the src tools (ldgeneric, readelf, nm, size, strip, elflint, findtextrel, elfcmp objdump, ranlib, ar and unstrip). Signed-off-by: Mark Wielaard <[email protected]>
| * addr2line: Set scopes to NULL after free in handle_address.Mark Wielaard2015-05-272-0/+5
| | | | | | | | | | | | | | If dwarf_getscopes_die () fails then scopes might not be reset and we could cause a double free. Signed-off-by: Mark Wielaard <[email protected]>
| * addr2line: Add --pretty-print option to show all information on one line.Mark Wielaard2015-05-272-11/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds an option --pretty-print to eu-addr2line to show all information on one line and all inlines on a line of their own. This mimics the same option from binutils addr2line, but without the short option variant -p. Since we already use -p to select the process. Example output: eu-addr2line --pretty-print -s -i -f -C -p$(pidof firefox) 0x00007f368c6f8915 mozilla::ReentrantMonitor::Wait(unsigned int) at ReentrantMonitor.h:92 (inlined by) mozilla::ReentrantMonitorAutoEnter::Wait(unsigned int) at ReentrantMonitor.h:190 A couple of tests were added to check the output matches that of binutils addr2line.

| * addr2line: Add demangler support.Mark Wielaard2015-05-273-7/+58
| | | | | | | | | | | | | | Makes the -C, --demangle option visible and implements it (ignoring the demangle style argument). Adds a new test with sample output. Signed-off-by: Mark Wielaard <[email protected]>
| * addr2line: Add -a, --address. Print address before for each entry.Mark Wielaard2015-05-272-1/+45
| | | | | | | | | | | | Adds test cases with sample output. Signed-off-by: Mark Wielaard <[email protected]>
| * addr2line: Always parse addresses as hex numbers.Mark Wielaard2015-05-272-2/+7
| | | | | | | | | | | | | | | | We would sometimes interpret input addresses as decimal or octal. That could be confusing and isn't what binutils addr2line does. Be consistent and always treat input addresses as hex. Signed-off-by: Mark Wielaard <[email protected]>
| * addr2line: Split options in input and output format groups.Mark Wielaard2015-05-272-3/+10
| | | | | | | | | | | | | | This makes it clear that -j, --section=NAME is about how input is treated, not how the output is formatted. Signed-off-by: Mark Wielaard <[email protected]>
| * strip: Harden against bogus input files. Don't leak tmp debug file on error.Mark Wielaard2015-05-182-77/+204
| | | | | | | | | | | | | | | | | | | | 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 Wielaard2015-05-133-13/+13
| | | | | | | | | | | | | | | | | | | | 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]>

| * elflint: Add sanity checks to check_attributes.Mark Wielaard2015-05-122-2/+6
| | | | | | | | | | | | | | | | | | | | This is similar to commit 9644aa for readelf print_attributes. Bail out when the vendor name isn't terminated and add overflow check for subsection_len. Note that readelf does handle non-gnu attributes, while elflint doesn't. Signed-off-by: Mark Wielaard <[email protected]>
| * elflint: Use Use Elf64_Word for shdr->sh_info cnt.Mark Wielaard2015-05-122-2/+8

| | | | | | | | | | | | | | mtrace is a GNU extension not supported by uClibc and it's believed to not be really used. Drop mtrace() calls and #include <mcheck.h>. Signed-off-by: Max Filippov <[email protected]>
| * Link against standalone argp libraryAnthony G. Basile2015-05-042-15/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | argp is not part of POSIX standards and not provided by uClibc or some other standard C libraries. However, it is possible to link against a breakout argp library. One is provided at http://www.lysator.liu.se/~nisse/misc/ This patch tests if libc provides argp otherwise it adds the linker flag -largp where needed in the build system.

| * readelf: Fix cie_offset calculation comparison on 32bit.Mark Wielaard2015-04-282-2/+8
| | | | | | | | | | | | | | | | | | gcc -fsanitize=undefined pointed out that on 32bit systems the calculation to match the cie_offset to the cie_id could be undefined because a cie_id could be an unsigned 64bit value while ptrdiff_t is only 32bits. Correct the calculation to use 64bit values. Signed-off-by: Mark Wielaard <[email protected]>

| * elflint: Correct gnu_symbias usage in compare_hash_gnu_hash.Mark Wielaard2015-03-132-14/+20
| | | | | | | | | | | | | | | | | | | | | | commit 0a545e "elflint: Add various low-level checks." introduced a bug in the handling of the gnu_symbias. The symbol in the bucket should first be compared to STN_UNDEF before applying the bias. And the used symbol index should have the bias added when compared against plain hash symbol.
