* debuginfod: debuginfod client should cache negative results.Alice Zhang via Elfutils-devel2021-05-061-0/+5
| | | | | | | | | | | | | | | | | | | | | Add debuginfod_config_cache for reading and writing to cache configuration files, make use of the function within debuginfod_clean_cache and debuginfod_query_server. In debuginfod_query_server, create 000-permission file on failed queries. Before querying each BUILDID, if corresponding 000 file detected, compare its stat mtime with parameter from .cache/cache_miss_s. If mtime is fresher, then return ENOENT and exit; otherwise unlink the 000 file and proceed to a new query. tests: add test in run-debuginfod-find.sh test if the 000 file is created on failed query; if querying the same failed BUILDID, whether the query should proceed without going through server; set the cache_miss_s to 0 and query the same buildid, and this time should go through the server.

* Prepare for 0.172.elfutils-0.172Mark Wielaard2018-06-111-0/+9
| | | | | | | | | | It has been only 10 days since the previous release and there are no functional changes compared to 0.171. The speedup of eu-readelf -N is pretty nice. And ~25 patches fix various bugs (hangs and crashes) in dealing with bad DWARF5 data. Most have been found by running the afl fuzzer on eu-readelf and various testcases.

* libdw: Add DW_MACRO constants and DW_MACRO_GNU compatibility defines.Mark Wielaard2017-08-021-1/+3
| | | | | | | | | | Accept version 5 .debug_macro format, which is identical to the GNU version 4 format. No real support yet for the new supplementary object file (sup) and indirect string references (strx). GCC doesn't generate them yet. readelf does recognize them, but doesn't try to decode them. dwarf_getmacros currently rejects the new formats. Signed-off-by: Mark Wielaard <mark@klomp.org>
* libdw: Handle DWARF5 immutable, packed and shared in dwarf_peel_type.Mark Wielaard2017-08-021-0/+1
| | | | | | | | | | Also update the documentation to explain that any type alias or modifier that doesn't modify, change the structural layout or the way to access the underlying type is peeled. Explicitly mention pointer and reference types as examples of modifiers that don't obey that rule and so aren't peeled. Signed-off-by: Mark Wielaard <mark@klomp.org>
* Handle DWARF5 defaulted member function encodings.Mark Wielaard2017-08-021-2/+2
| | | | | | | | | Add DW_DEFAULTED_no, DW_DEFAULTED_in_class and DW_DEFAULTED_out_of_class to dwarf.h. Print value (no, in_class or out_of_class) of DW_AT_defaulted in readelf. Signed-off-by: Mark Wielaard <mark@klomp.org>

* libdw: Add DWARF5 attributes.Mark Wielaard2017-08-021-0/+2
| | | | | | | | | | | | Add new DWARF5 attribute constant names to the attributes enum. Also add reserved comments between non-consecutive (reserved) numbers. Remove DW_AT_subscr_data, DW_AT_element_list and DW_AT_member from the enum list and turn them into compatibility defines because they are not part of DWARF2+. That way code that directly references them still compiles but they won't show up in known-dwarf.h. Signed-off-by: Mark Wielaard <mark@klomp.org>
* backends: Don't depend on linux/bpf.h to compile bpf disassembler.Mark Wielaard2017-07-241-0/+2
| | | | | | | | | We only need a few constants and one structure definition from linux/bpf. Just define those in a local lib/bpf.h file. This makes sure the bpf disassembler is always build and included even when elfutils is build on older GNU/Linux systems (and even on other platforms). Signed-off-by: Mark Wielaard <mark@klomp.org>
* strip: Add --keep-section=SECTION and --remove-section=SECTION.Mark Wielaard2017-07-171-0/+4
| | | | | | | | | | | | | | | | | | | | | Adds two new output options: --keep-section=SECTION Keep the named section. SECTION is an extended wildcard pattern. May be given more than once. --remove-section=SECTION Remove the named section. SECTION is an extended wildcard pattern. May be given more than once. Only non-allocated sections can be removed. The --remove-section was already partially implemented, but only for the .comment section. The short option -R is to be compatible with binutils. The new testcase makes sure that various combinations of kept/removed sections pull the correct dependencies into the output and/or debug files. https://bugzilla.redhat.com/show_bug.cgi?id=1465997 Signed-off-by: Mark Wielaard <mark@klomp.org>

| | | | | | | | | | | | We want eu- as default program prefix if none was given by the user. But if the user explicitly provided --program-prefix="" then pretend it wasn't set at all (NONE). This makes sure all tools will be installed as eu-<program>. We want this default since most tools would normally conflict with the GNU binutils variants that have similar names.

* addr2line: Add --pretty-print option to show all information on one line.Mark Wielaard2015-05-271-0/+1
| | | | | | | | | | | | | | | | | | 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: Always parse addresses as hex numbers.Mark Wielaard2015-05-271-0/+3
| | | | | | | | 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 <mjw@redhat.com>
* Publish known-dwarf.hPetr Machata2015-03-311-0/+4
| | | | | | | | | | | | | - Make the macro names properly scoped (DWARF_ALL_KNOWN_* and DWARF_ONE_KNOWN_*). - Simplify the calling convention: don't keep track of the comment associated with the enumerator, always use the non-_DESC DWARF_ONE_KNOWN_* callback. - Install known-dwarf.h alongside libdw.h and others.

* Change calling convention of dwarf_getmacros to allow opcode 0xffPetr Machata2014-12-101-2/+0
| | | | | | | | | We now require callers to pass DWARF_GETMACROS_START to start the iteration. 0 is still accepted, but signals to libdw that the iteration request comes from an old-style caller, and that opcode 0xff should be rejected when iterating .debug_macro, to avoid confusion. Signed-off-by: Petr Machata <pmachata@redhat.com>
* Support .debug_macroPetr Machata2014-11-101-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - This code is based on the following proposal: http://www.dwarfstd.org/ShowIssue.php?issue=110722.1 - dwarf_getmacros serves either of .debug_macinfo or .debug_macro transparently, but if the latter uses opcode 0xff, it bails out with an error. The reason is that in .debug_macro, 0xff is a custom code that can mean anything, while in .debug_macinfo there's fixed semantics associated with 0xff. - dwarf_getmacros_off is a new interface used for requesting iteration through transparently included units. - dwarf_macro_getparamcnt and dwarf_macro_param are new interfaces used for requesting number of parameters of an opcode and individual parameters. dwarf_macro_getsrcfiles is a new interface used for requesting a file part of .debug_line unit associated with macro unit that the opcode comes from. - The existing interfaces dwarf_macro_opcode, dwarf_macro_param1 and dwarf_macro_param2 remain operational for old- as well as new-style Dwarf macro sections, if applicable. - dwarf_getsrclines was made into a light wrapper around a worker function that loads line unit given its offset. The worker also caches loaded units in an offset-keyed search tree, so that we don't end up re-reading units even though they were read in a different domain (e.g. a macro unit request can prime cache for later CU lookup). dwarf_macro_getsrcfiles calls the worker function under covers.

* libdw: Add dwarf_peel_type. Use it in dwarf_aggregate_size.Mark Wielaard2014-11-051-0/+5
| | | | | | | | | | | | | | | Add new function dwarf_peel_type. Some type annotations in DWARF are specified by modifier tag type wrappers instead of attributes. For type aliases (typedef) and qualifiers (const, volatile, restrict) tags dwarf_peel_type follows the DW_AT_type attributes till it finds a base, user-defined, reference or pointer type DIE. Use this new function in the backends for return type DIEs (replacing the existing dwarf_peel_type there) and in dwarf_aggregate_size so it can provide the sizes for qualified types too. Add a new version and testcase for the new dwarf_aggregate_size functionality. Signed-off-by: Mark Wielaard <mjw@redhat.com>
