main	2024-10-02 14:49:22 UTC 2024-10-02	debugedit: switch to xxhash for buildid recomputation Author: Frank Ch. Eigler Author Date: 2024-09-24 19:34:44 UTC debugedit: switch to xxhash for buildid recomputation When debugedit recomputes build-id (due to -i), it previously used md5 or sha1 (depending on length of incoming buildid). This patch replaces both those (including the code that does all the hashing) with a 128-bit xxhash. The 128-bit hash is truncated or padded to whatever the incoming ELF note width was. xxhash is much faster (8x over sha1) than either of those crypto-flavoured hashes, and still produces fairly collision-free values. This was confirmed informally with a bulk build-id recomputation of a few million binaries in the debuginfod server corpus, yielding zero unexpected collisions. Signed-off-by: Frank Ch.
