522397d05e7d4a7c30b91841492360336b24f833 - resolve_btfids: Change in-place update with raw binary output

Fri, 19 Dec 2025 19:18:25 +0100

resolve_btfids: Change in-place update with raw binary outputCurrently resolve_btfids updates .BTF_ids section of an ELF filein-place, based on the contents of provided BTF, usually within thesame input file, and optionally a BTF base.Change resolve_btfids behavior to enable BTF transformations as partof its main operation. To achieve this, in-place ELF write inresolve_btfids is replaced with generation of the following binaries: * ${1}.BTF with .BTF section data * ${1}.BTF_ids with .BTF_ids section data if it existed in ${1} * ${1}.BTF.base with .BTF.base section data for out-of-tree modulesThe execution of resolve_btfids and consumption of its output isorchestrated by scripts/gen-btf.sh introduced in this patch.The motivation for emitting binary data is that it allows simplifyingresolve_btfids implementation by delegating ELF update to the $OBJCOPYtool [1], which is already widely used across the codebase.There are two distinct paths for BTF generation and resolve_btfidsapplication in the kernel build: for vmlinux and for kernel modules.For the vmlinux binary a .BTF section is added in a roundabout way toensure correct linking. The patch doesn't change this approach, onlythe implementation is a little different.Before this patch it worked as follows: * pahole consumed .tmp_vmlinux1 [2] and added .BTF section with llvm-objcopy [3] to it * then everything except the .BTF section was stripped from .tmp_vmlinux1 into a .tmp_vmlinux1.bpf.o object [2], later linked into vmlinux * resolve_btfids was executed later on vmlinux.unstripped [4], updating it in-placeAfter this patch gen-btf.sh implements the following: * pahole consumes .tmp_vmlinux1 and produces a *detached* file with raw BTF data * resolve_btfids consumes .tmp_vmlinux1 and detached BTF to produce (potentially modified) .BTF, and .BTF_ids sections data * a .tmp_vmlinux1.bpf.o object is then produced with objcopy copying BTF output of resolve_btfids * .BTF_ids data gets embedded into vmlinux.unstripped in link-vmlinux.sh by objcopy --update-sectionFor kernel modules, creating a special .bpf.o file is not necessary,and so embedding of sections data produced by resolve_btfids isstraightforward with objcopy.With this patch an ELF file becomes effectively read-only withinresolve_btfids, which allows deleting elf_update() call and satellitecode (like compressed_section_fix [5]).Endianness handling of .BTF_ids data is also changed. Previously the"flags" part of the section was bswapped in sets_patch() [6], and thenElf_Type was modified before elf_update() to signal to libelf thatbswap may be necessary. With this patch we explicitly bswap entiredata buffer on load and on dump.[1] https://lore.kernel.org/bpf/131b4190-9c49-4f79-a99d-c00fac97fa44@linux.dev/[2] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/scripts/link-vmlinux.sh?h=v6.18#n110[3] https://git.kernel.org/pub/scm/devel/pahole/pahole.git/tree/btf_encoder.c?h=v1.31#n1803[4] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/scripts/link-vmlinux.sh?h=v6.18#n284[5] https://lore.kernel.org/bpf/20200819092342.259004-1-jolsa@kernel.org/[6] https://lore.kernel.org/bpf/cover.1707223196.git.vmalik@redhat.com/Signed-off-by: Ihor Solodrai Signed-off-by: Andrii Nakryiko Tested-by: Alan Maguire Acked-by: Eduard Zingerman Link: https://lore.kernel.org/bpf/20251219181825.1289460-3-ihor.solodrai@linux.dev List of files: /linux/scripts/Makefile.modfinal

Fri, 05 Dec 2025 18:37:41 +0100

Merge tag 'tracepoints-v6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-tracePull unused tracepoints update from Steven Rostedt: "Detect unused tracepoints. If a tracepoint is defined but never used (TRACE_EVENT() created but no trace_() called), it can take up to or more than 5K of memory each. This can add up as there are around a hundred unused tracepoints with various configs. That is 500K of wasted memory. Add a make build parameter of "UT=1" to have the build warn if an unused tracepoint is detected in the build. This allows detection of unused tracepoints to be upstream so that outreachy and the mentoring project can have new developers look for fixing them, without having these warnings suddenly show up when someone upgrades their kernel. When all known unused tracepoints are removed, then the "UT=1" build parameter can be removed and unused tracepoints will always warn. This will catch new unused tracepoints after the current ones have been removed. Summary: - Separate out elf functions from sorttable.c Move out the ELF parsing functions from sorttable.c so that the tracing tooling can use it. - Add a tracepoint verifier tool to the build process If "UT=1" is added to the kernel command line, any unused tracepoints will trigger a warning at build time. - Do not warn about unused tracepoints for tracepoints that are exported There are sever cases where a tracepoint is created by the kernel and used by modules. Since there's no easy way to detect if these are truly unused since the users are in modules, if a tracepoint is exported, assume it will eventually be used by a module. Note, there's not many exported tracepoints so this should not be a problem to ignore them. - Have building of modules also detect unused tracepoints Do not only check the main vmlinux for unused tracepoints, also check modules. If a module is defining a tracepoint it should be using it. - Add the tracepoint-update program to the ignore file The new tracepoint-update program needs to be ignored by git"* tag 'tracepoints-v6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: scripts: add tracepoint-update to the list of ignores files tracing: Add warnings for unused tracepoints for modules tracing: Allow tracepoint-update.c to work with modules tracepoint: Do not warn for unused event that is exported tracing: Add a tracepoint verification check at build time sorttable: Move ELF parsing into scripts/elf-parse.[ch] List of files: /linux/scripts/Makefile.modfinal
