* debuginfod: Support queries for ELF/DWARF sectionsAaron Merey2022-11-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | Add new function debuginfod_find_section which queries debuginfod servers for the raw binary contents of the specified ELF/DWARF section in a file matching the given build-id. Extend the server webapi to support section queries. Section query URLS have the following format: /buildid/BUILDID/section/SECTION The server will attempt to extract the section from a debuginfo file matching the given build-id. If the debuginfo file cannot be found or the section has type SHT_NOBITS, the server will attempt to extract the section from the executable file matching the build-id. If the server is built without section query support, the client will attempt to download the debuginfo matching the build-id and extract the section. If the debuginfo file cannot be found or the section has type SHT_NOBITS, the server will attempt to download the executable file matching the build-id and extract the section.

* debuginfod-client: Add DEBUGINFOD_HEADERS_FILE.Daniel Thornburgh2022-10-281-0/+3
| | | | | | | | This DEBUGINFOD_HEADERS_FILE environment variable names a file to supply HTTP headers to outgoing requests. Notably, this allows for Authorization headers to be added from a file under OS access control. Signed-off-by: Daniel Thornburgh <dthorn@google.com>
* libdwfl: add dwfl_report_offline_memoryAleksei Vetrov2022-10-161-0/+1
| | | | | | | | | | | | | This method allows to read and report ELF from memory instead of opening a file. That way arbitrary memory can be worked with, e.g. when coming from a stream without the need to persist. Another useful application is for fuzzing, because fuzzers might be able to track accesses to the memory and change the fuzzer input to cover more edge cases through more targeted input. Hence, add a new function along with a test case. Signed-off-by: Aleksei Vetrov <vvvvvv@google.com>
* readelf: Support --dynamic with --use-dynamicDi Chen2022-08-011-0/+2
| | | | | | | | | | | | Currently, eu-readelf is using section headers to dump the dynamic segment information (print_dynamic -> handle_dynamic). This patch adds new options to eu-readelf (-D, --use-dynamic) for (-d, --dynamic). https://sourceware.org/bugzilla/show_bug.cgi?id=28873 Signed-off-by: Di Chen <dichen@redhat.com>
* libdwfl: Add new function dwfl_frame_regDi Chen2022-07-311-0/+1
| | | | | | | | | | | | | | Dwfl has most of the infrastructure to keep the full unwind state, including the state of unwound registers per frame using Dwfl_Thread_Callbacks. But there is no public API to access the state, except for the PC (dwfl_frame_pc). This commit adds a new function dwfl_frame_reg to get the value of the DWARF register number in the given frame. https://sourceware.org/bugzilla/show_bug.cgi?id=28579 Signed-off-by: Di Chen <dichen@redhat.com>

* PR28661: debuginfo connection thread pool supportFrank Ch. Eigler2021-12-101-0/+5
| | | | | | | | | | | | Add an option -C, which activates libmicrohttpd's thread-pool mode for handling incoming http connections. Add libmicrohttpd error-logging callback function so as to receive indication of its internal errors, and relay counts to our metrics. Some of these internal errors tipped us off to a microhttpd bug that thread pooling works around. Document in debuginfod.8 page. Hand-tested against "ulimit -u NNN" shells, and with a less strenuous new test case. Signed-off-by: Frank Ch. Eigler <fche@redhat.com>

* libdw, readelf: Read inlining info in NVIDIA extended line mapJohn M Mellor-Crummey2021-11-101-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As of CUDA 11.2, NVIDIA added extensions to the line map section of CUDA binaries to represent inlined functions. These extensions include - two new fields in a line table row to represent inline information: context, and functionname, - two new DWARF extended opcodes: DW_LNE_NVIDIA_inlined_call, DW_LNE_NVIDIA_set_function_name, - an additional word in the line table header that indicates the offset in the .debug_str function where the function names for this line table begin, and A line table row for an inlined function contains a non-zero "context" value. The “context” field indicates the index of the line table row that serves as the call site for an inlined context. The "functionname" field in a line table row is only meaningful if the "context" field of the row is non-zero. A meaningful "functionname" field contains an index into the .debug_str section relative to the base offset established in the line table header; the position in the .debug_str section indicates the name of the inlined function. These extensions resemble the proposed DWARF extensions (http://dwarfstd.org/ShowIssue.php?issue=140906.1) by Cary Coutant, but are not identical. This commit integrates support for handling NVIDIA's extended line maps into elfutil's libdw library, by adding two functions dwarf_linecontext and dwarf_linefunctionname, and the readelf --debug-dump=line command line utility.

* PR28514: debuginfod: limit groom operation timesFrank Ch. Eigler2021-11-051-0/+1
| | | | | | | | | | | | | | | | | | | For large databases and many stale files, it was possible to starve rescan operations by numerous groom "nuke" (database delete ops). Under the theory that including new data is at least as important as aging old, we now impose a rough deadline on groom queries. In the process, we discovered that we were commiting some undefined-behaviour sqlite ops (deleting rows while iterating), which may explain some previous heisenbug occurrences. So the groom nuke operations are split into decision & action phases, with associated progress-tracking metrics. Testing the timeout facility requires hand-testing beyond the testsuite (since it requires LARGE databases to show measurable query times). So confirmed this part by hand. Signed-off-by: Frank Ch.

* 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.
