openSUSE Recommended Update: Recommended update for dwarves ______________________________________________________________________________ Announcement ID: openSUSE-RU-2021:0216-1 Rating: moderate References: #1176095 #1177921 Affected Products: openSUSE Leap 15.2 ______________________________________________________________________________ An update that has two recommended fixes can now be installed. Description: This update for dwarves fixes the following issues: + DW_AT_alignment is defined in 1.19 so dwarves now is compatible with older libdw. Update to release 1.19 * Support for split BTF. * Support cross-compiled ELF binaries with different endianness. * Support for showing typedefs for anonymous types, like structs, unions and enums. Move to 1.18.g19 (863e6f0f) * btf_encoder: Ignore zero-sized ELF symbols update to 1.18_15g040fd7f (boo#1177921): * btf_encoder: Support cross-compiled ELF binaries with different endianness * strings: use BTF's string APIs for strings management * strings: Rename strings.h to avoid clashing with /usr/include/strings.h * dwarf_loader: increase the size of lookup hash map * btf_encoder: revamp how per-CPU variables are encoded * btf_encoder: Discard CUs after BTF encoding * btf_encoder: Fix emitting __ARRAY_SIZE_TYPE__ as index range type * btf_encoder: Use libbpf APIs to encode BTF type info * btf_loader: Use libbpf to load BTF * dwarves: Expose and maintain active debug info loader operations * btf_encoder: detect BTF encoding errors and exit * libbpf: Update to latest libbpf version * dwarf_loader: Conditionally define DW_AT_alignment * pahole: Implement --packed * man-pages: Fix 'coimbine' typo Update to release 1.18 * pahole now should be segfault free when handling gdb test suit DWARF files, including ADA, FORTRAN, rust and dwp compressed files (the latter is refused). * Bail out on partial units for now, avoiding segfaults. - Backport fixes for segfault when processing dwz-ed kernel [boo#1176095,https://github.com/acmel/dwarves/issues/10]. Update to release 1.17 * Support raw BTF as available in /sys/kernel/btf/vmlinux. * Make --find_pointers_to consider unions. * Make --contains and --find_pointers_to honour --unions. * Add support for finding pointers to void. * Make --contains and --find_pointers_to to work with base types. Update to release 1.16 * btf_loader: Add support for BTF_KIND_FUNC Update to new upstream release 1.15 * Avoid null dereference with NULL configs * Fixup printing "const" early with "const void" * Fix recursively printing named structs in --expand_types version 1.13 * Use of the recently introduced BTF deduplication algorithm * Introduce a 'btfdiff' utility * Add a BTF loader, i.e. 'pahole -F btf' allows pretty printing of structs and unions in the same fashion as with DWARF info * Better union support * Infer __attribute__((__packed__)) when structs have no alignment holes * Support DWARF5's DW_AT_alignment * Add a '--compile' option to 'pfunct' Update to new upstream release 1.12 * Added a BTF (BPF Type Format) encoder * Initial support for DW_TAG_partial_unit * Print cacheline boundaries in multiple union members * Show offsets at union members Patch Instructions: To install this openSUSE Recommended Update use the SUSE recommended installation methods like YaST online_update or "zypper patch".
