Subject: [PATCH v1 01/11] perf aslr: Add missing includes and sort headers
Date: Wed, 16 Sep 2026 21:53:16 -0700 [thread overview]
Message-ID: <20260917045326.63601-1-irogers@google.com> (raw)
Sashiko reported:
When building the perf utility against strict C standard libraries
such as musl libc, compilation fails in tools/perf/util/aslr.c due
to missing explicit inclusions of <stdlib.h> and <string.h>.
The implementation relies on standard memory management and string
functions like malloc(), free(), memcpy(), and memset() in routines
such as aslr_tool__findnew_mapping(), aslr_tool__process_sample(),
and aslr_tool__delete(). Because the required headers are omitted,
the compiler must resolve these calls via implicit function
declarations. While glibc may transitively provide these definitions
via other headers, musl libc does not. This violates strict C99+
standard compliance and triggers fatal build errors under modern
compiler configurations.
Add the header files and use git clang-format to sort.
