Follow-up series to [1] to address some suggestions from Andrii to improve parsing and make it more robust (patches 1, 2) and to improve validation of u[ret]probe firing by validating expected argument and return values (patch 3). [1] https://lore.kernel.org/bpf/164903521182.13106.12656654142629368774.git-patchwork-notify@xxxxxxxxxx/ Changes since v1: - split library name, auto-attach parsing into separate patches (Andrii, patches 1, 2) - made str_has_sfx() static inline, avoided repeated strlen()s by storing lengths, used strlen() instead of strnlen() (Andrii, patch 1) - fixed sscanf() arg to use %li, switched logging to use "prog '%s'" format, used direct strcmp() on probe_type instead of prefix check (Andrii, patch 2) - switched auto-attach tests to log parameter/return values to be checked by user-space side of tests. Needed to add pid filtering to avoid capturing stray malloc()s (Andrii, patch 3) Alan Maguire (3): libbpf: improve library identification for uprobe binary path resolution libbpf: improve string parsing for uprobe auto-attach selftests/bpf: uprobe tests should verify param/return values tools/lib/bpf/libbpf.c | 85 +++++++++------------- tools/lib/bpf/libbpf_internal.h | 11 +++ .../selftests/bpf/prog_tests/uprobe_autoattach.c | 25 +++++-- .../selftests/bpf/progs/test_uprobe_autoattach.c | 43 ++++++++--- 4 files changed, 96 insertions(+), 68 deletions(-) -- 1.8.3.1
