* libdwelf: add dwelf_elf_remove_debug_relocsupstream/users/amerey/try-remove-relocs2Di Chen2024-10-189-348/+513
| | | | | | | | | | | | | Provide a public function for removing debug section relocations. eu-strip previously contained the code to remove debug section relocations. This patch moves that code into dwelf_elf_remove_debug_relocs. https://sourceware.org/bugzilla/show_bug.cgi?id=31447 Signed-off-by: Di Chen <[email protected]> Signed-off-by: Aaron Merey <[email protected]>

* eu-stacktrace [4/5]: src: add unwind origin diagnostics to eu-stackSerhei Makarov2024-10-172-8/+37
| | | | | | | | | | | | | | | | | | | Since we obtain diagnostics about unwind method, another logical place to show them is in eu-stack. * src/stack.c (show_unwound_source): New global variable. (struct frame): Add unwound_source field. (frame_callback): Copy over unwound_source from Dwfl_Frame. (print_frame): Take unwound_source string and print it. (print_inline_frames): Take unwound_source argument and pass it on, except for subsequent frames where we pass the string "inline". (print_frames): Take unwound_source field from struct frame and pass it on. (parse_opt): Add --cfi-type,-c option to set show_unwound_source. (main): Ditto. * tests/run-stack-i-test.sh: Add testcase for --cfi-type. Signed-off-by: Serhei Makarov <[email protected]>
* eu-stacktrace [3/5]: libdwfl: add unwind origin diagnosticsSerhei Makarov2024-10-176-11/+96
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Track the method used to unwind each Dwfl_Frame using an enum field unwound_source; provide access to the field. Then use that in eu-stacktrace to display the unwind methods used for each process. This is an important diagnostic to verify how many processes are adequately covered by the eh_frame unwinder. * libdw/libdw.map (ELFUTILS_0.192): Add dwfl_frame_unwound_source, dwfl_unwound_source_str. * libdwfl/libdwfl.h (Dwfl_Unwound_Source): New enum. (dwfl_frame_unwound_source) (dwfl_unwound_source_str): New functions. * libdwfl/dwfl_frame.c (dwfl_frame_unwound_source) (dwfl_unwound_source_str): New functions. * libdwfl/libdwflP.h: Add INTDECL for dwfl_frame_unwound_source, dwfl_unwound_source_str. (struct Dwfl_Frame): Add unwound_source field. * libdwfl/frame_unwind.c (__libdwfl_frame_unwind): Set state->unwound_source depending on the unwind method used. * src/stacktrace.c (struct sysprof_unwind_info): Add last_pid field to provide access to the current sample's dwfltab entry. (sysprof_unwind_frame_cb): Add unwound_source to the data displayed with the show_frames option. (sysprof_unwind_cb): Set last_pid when processing a sample. (main): Add unwind_source to the data displayed in the final summary table. Signed-off-by: Serhei Makarov <[email protected]>
* eu-stacktrace [2/5]: configure.ac: initial version (x86/sysprof only)Serhei Makarov2024-10-172-2/+63
| | | | | | | | | | | | | | | | | | | | | Due to the x86-specific code in the initial version the configury has significant restrictions. If --enable-stacktrace is not explicitly provided, then eu-stacktrace will be disabled by default. The way we test for x86 is a bit unusual. What we actually care about is that the register file provided by perf_events on the system is an x86 register file; this is done by checking that <asm/perf_regs.h> is Linux kernel arch/x86/include/uapi/asm/perf_regs.h. Once eu-stacktrace is properly portable across architectures, these grody checks can be simplified. Enablement of the feature by default depends on a released Sysprof version we can point to for the patches. * configure.ac: Add configure checks and conditionals for stacktrace tool. * src/Makefile.am: Add stacktrace tool conditional on ENABLE_STACKTRACE.

* eu-stacktrace [1/5]: src: add eu-stacktrace toolSerhei Makarov2024-10-171-0/+1571
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | eu-stacktrace is a utility to process a stream of raw stack samples (such as those obtained from the Linux kernel's PERF_SAMPLE_STACK facility) into a stream of stack traces (such as those obtained from PERF_SAMPLE_CALLCHAIN), freeing other profiling utilities from having to implement their own backtracing logic. eu-stacktrace accepts data from a profiling tool via a pipe or fifo. The initial version of the tool works on x86 architectures and accepts data from Sysprof [1]. For future work, it will make sense to expand support to other profilers, in particular perf tool. Further patches in this series provide configury, docs, and improved diagnostics for tracking the method used to unwind each frame in the stack trace. [1]: The following patched version of Sysprof (upstream submission ETA ~very_soon) can produce data with stack samples: https://git.sr.ht/~serhei/sysprof-experiments/log/serhei/samples-via-fifo Invoking the patched sysprof with eu-stacktrace: $ sudo sysprof-cli --use-stacktrace $ sudo sysprof-cli --use-stacktrace --stacktrace-path=/path/to/eu-stacktrace Invoking the patched sysprof and eu-stacktrace manually through a fifo: $ mkfifo /tmp/test.fifo $ sudo eu-stacktrace --input /tmp/test.fifo --output test.syscap & $ sysprof-cli --sample-method=stack --use-fifo=/tmp/test.fifo test.syscap Note that sysprof polkit actions must be installed systemwide (e.g. installing the system sysprof package will provide these). Otherwise, "Action org.gnome.sysprof3.profile is not registered" error will result. * src/stacktrace.c: Add new tool. Signed-off-by: Serhei Makarov <[email protected]>
* Remove usage of "unlocked" variant of stdio print functionsMichael Pratt2024-10-179-91/+91
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These "unlocked" Linux Standard Base variants of standard functions are not available on some systems that are still capable of building Linux and ELFs. The difference is negligible for simple printing to stdout. POSIX also states for the similar putc_unlocked(): These functions can safely be used in a multi-threaded program if and only if they are called while the invoking thread owns the (FILE *) object, as is the case after a successful call to the flockfile() or ftrylockfile() functions. ... These unlocked versions can be safely used only within explicitly locked program regions, using exported locking primitives. and these precautions were never done. Use the standard forms of these print functions. There is inconsistent use of fputc_unlocked() with putc_unlocked(), so consistently use the safer fputc() instead.

* PR32218: debuginfod-client: support very long source file namesFrank Ch. Eigler2024-10-168-47/+162
| | | | | | | | | | | | | | | | | | | | | | | | | | | | debuginfod clients & servers may sometimes encounter very long source file names. Previously, the client would synthesize a path name like $CACHEDIR/$BUILDID/source-$PATHNAME where $PATHNAME was a funky ##-encoded version of the entire source path name. See https://sourceware.org/PR32218 for a horror case. This can get too long to store as a single component of a file system pathname (e.g. linux/limits.h NAME_MAX), resulting on client-side errors even after a successful download. New code switches encoding of the $PATHNAME part to use less escaping, and a merciless truncation to the tail part of the filename. (We keep the tail rather than the head, so that the extension is preserved, which makes some consumers happier.) To limit collision damage from truncation, we add also insert a goofy hash (4-byte DJBX33A) of the name into the path name. The result is a relatively short name: $CACHEDIR/$BUILDID/source-$HASH-$NAMETAIL This is a transparent change to clients, who are not to make any assumptions about cache file naming structure. However, one existing test did make such assumptions, so is fixed with some globness. A new test is also added, using a pre-baked tarball with a very long srcfile name. Signed-off-by: Frank Ch.

* libdw: Let clean targets be unconditionalMichael Pratt2024-10-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | The automake rule "maintainer-clean-generic" is always available and never conditional, so let the variable that uses it be define non-conditionally. If one actually wants conditional cleaning they should write a custom rule and set it as a dependency of a "*clean-local" automake rule. There is no need to do conditional cleaning here, so move the MAINTAINERCLEANFILES variable definition to the end of the Makefile.am file as it is in the rest of the project. * libdw/Makefile.am: move MAINTAINERCLEANFILES variable to the end of the file as a non-conditional definition.

* libcpu: Include config.h before standard headers in lexer sourceMichael Pratt2024-10-141-4/+6
| | | | | | | | | | | | | | | | | As part of the processing of flex, definitions and headers are added to output source before any literal text or generated code. This causes standard headers to come before config.h unless config.h is included in a %top block instead as specified in the flex manual, section 5.1 "Format of the Definitions". The %top block is non-POSIX, so using it reinforces the requirement of "flex" over a standardized "lex" even more. * libcpu/i386_lex.l (%top): add flex %top block and move config.h header inclusion to it.

* tests/test-subr.sh: Put test_dir under /var/tmp.Frank Ch. Eigler2024-10-101-2/+3
| | | | | | | | | | | | | | | | | Every individual test in elfutils involves a temporary directory. Previous version of this script put that directory under the build tree. That's OK if it's a local disk, but if it's on NFS, then some tests - run-large-elf-file.sh, several run-debuginfod-*.sh - take long enough to run to fail tests intermittently. This patch moves the temp_dir under ${TMPDIR-/var/tmp/}, so it operates at local disk speed rather than whatever-build-filesystem speed. Individual test scripts are all unaffected. (One could consider /tmp instead, which is a RAM disk on modern systems, except that some of the elfutils tests produce GB-sized temporary files. That's probably too big for RAM.)

* debuginfod: service metadata queries in separate, timed-out connectionsFrank Ch. Eigler2024-09-031-15/+67
| | | | | | | | | | | | | | | | | | | | | | | | | The --metadata-maxtime=SECONDS parameter was intended to limit elapsed time debuginfod spends attempting to answer metadata queries. These can be slow because they have to apply glob matches across a large set of strings, potentially taking many seconds. However, this option was not implemented fully. It checked for timeouts only when rows of data were finally served up by the database, not during. Also, it used the same database connection that normal debuginfod queries were using, locking them out. New code creates a new temporary database connection for these infrequent(?) metadata queries, and enforces timeouts using the sqlite3 progress-handler callback. This effectively limits total query runtime, inside or outside the database. The elfutils testsuite dataset is not large enough to show either the slow-glob or the locking-out-normal-queries phenomenon, so the behavioral impact was hand-tested on a moderate sized debuginfod index on a live federation server. A full valgrind leak check indicated it's clean. Signed-off-by: Frank Ch. Eigler <[email protected]>
