* libdw: check that DWARF strings are null-terminatedAleksei Vetrov2023-02-173-1/+52
| | | | | | | | | | | | It is expected from libdw to return strings that are null-terminated to avoid overflowing ELF data. * Add calculation of a safe prefix inside string sections, where any string will be null-terminated. * Check if offset overflows the safe prefix in dwarf_formstring.

* libdw: Handle DW_OP_GNU_uninit in dwarf_getlocationMark Wielaard2023-02-144-0/+16
| | | | | | | | | | | dwarf_getlocation would return an error when it saw a DW_OP_GNU_uninit. Handle it by simply recognizing as a no argument operation. DW_OP_GNU_uninit is emitted by GCC as a marker to flag the location expression as referring to an uninitialized value. Signed-off-by: Mark Wielaard <mark@klomp.org>

* libdw: check memory access in get_(u|s)leb128Aleksei Vetrov2023-02-142-3/+36
| | | | | | | | | | __libdw_get_uleb128 and __libdw_get_sleb128 should check if addrp has already reached the end before unrolling the first step. It is done by moving __libdw_max_len to the beginning of the function, which can notice, that addrp is beyond the end. Then we just check the result of this function.

* backends: Handle DW_TAG_unspecified_type in dwarf_peeled_die_typeMark Wielaard2023-02-145-3/+40
| | | | | | | | | | | | | | | | binutils 2.40 introduces DW_TAG_unspecified_type for assembly functions with an unknown return type. This breaks the run-funcretval.sh testcase because dwfl_module_return_value_location returns an error for such functions because it cannot determine the return value location. Fix that by treating DW_TAG_unspecified_type as if the DIE doesn't have a DW_AT_type. Also update the testcase to explicitly checking for DW_TAG_unspecified_type and printing "returns unspecified type". https://sourceware.org/bugzilla/show_bug.cgi?id=30047 Signed-off-by: Mark Wielaard <mark@klomp.org>
* configure: Add --enable-sanitize-memoryIlya Leoshkevich2023-02-149-5/+56
| | | | | | | | | | | | | | | | | | | | Add support for clang Memory Sanitizer [1], which detects the usage of uninitialized values. While elfutils itself is already checked with valgrind, checking code that depends on elfutils requires elfutils to be built with MSan. MSan is not linked into shared libraries, and is linked into executables statically. Therefore, unlike the other sanitizers, MSan needs to be configured fairly early, since we need to drop -D_FORTIFY_SOURCE [2], -Wl,-z,defs and --no-undefined. Disable a few tests that run for more than 5 minutes due to test files being statically linked with MSan.

* debuginfod-client.c: Download section even if cached executable didn't ↵Aaron Merey2023-02-072-10/+21
| | | | | | | | | | | | | | | | | | | | | contain it. Before attempting to download a section, cache_find_section tries to extract the section from existing files in the cache. If it's determined that the section must not exist, cache_find_section returns -ENOENT to indicate that the download should be skipped. This patch fixes a bug where cache_find_section returns -ENOENT even though the section exists. If the cache contains the executable but not the debuginfo with the given build-id and the section only exists in the debuginfo (such as any of the .debug_* sections), then debuginfod_find_section returns -ENOENT even if the section could be downloaded. Fix this by having cache_find_section not return -ENOENT unless cached debuginfo was able to be read. Signed-off-by: Aaron Merey <amerey@redhat.com>

So make sure to search in the We also tried to add the origin match in pc_record directly in the current inlined scope. This always failed, causing to do a needless traversal, followed by the full CU scan in dwarf_getscopes. Just always stop the pc_record search and then do the CU origin_match in dwarf_getscopes.

* addr2line: -C should not try to handle optional (ignored) argumentMark Wielaard2023-01-305-2/+110
| | | | | | | | | | | | | | | | The --demangle option takes an option (ignored) argument. Since -C is the short option of --demangle it also takes that optional argument. But that means that something like -Cfi is like -C got fi as argument, while the user expects -Cfi to be like -C -f -i. Separate the --demangle and -C options. --demangle still takes an optional (ignored) argument, but -C doesn't take any arguments so -Cfi acts the same as -fiC. Also fix --target, -b, so that it is properly ignored (and not accidentially enables demangling). Signed-off-by: Mark Wielaard <mark@klomp.org>

* debuginfod-find.1: note on how to find a comp_dirSerhei Makarov2023-01-131-0/+13
| | | | | | | | | | | | | | | | | | | | | | doc/ChangeLog: * debuginfod-find.1: add a note to DESCRIPTION section for the 'source' subcommand, clarifying where to find the CU compilation-directory. I'm looking at how to improve and document the workflow for using debuginfod-find to study the behaviour of packaged software on a system, e.g. in conjunction with a tracing tool like SystemTap. You can read the exact compiled source code with debuginfod-find source and use that to figure out which source code locations are interesting to trace. But that process has several non-obvious or inconvenient steps. This patch is a clarification to the debuginfod-find source man page pointing out the eu-readelf command that can show the comp_dir in downloaded debuginfo. Since debuginfod-find source could be picked up and used by a developer unfamiliar with DWARF terminology, I think such a clarification saves time for newbies figuring out what a CU compilation-directory is.

This results in the older identifiers being used and they now generate errors when compiled against Curl 7.87, which has silently deprecated them, causing GCC to emit `-Werror=deprecated-declarations`. Instead, the newer identifiers were added in Curl 7.55, so explicitly check for `CURL_AT_LEAST_VERSION(7, 55, 0)` instead of the current logic. This eliminates the error when compiling against Curl 7.87. Ref: https://github.com/curl/curl/pull/1511 Signed-off-by: Andrew Paprocki <andrew@ishiboo.com>
