David Lee is here marked as the author but didn't even Signed-off-by the patch. See https://docs.kernel.org/process/submitting-patches.html#sign-your-work-the-developer-s-certificate-of-origin (see the end of mail of pending things for this patch) @Konstanin (Joe/Andy): Is it to be expected that `b4 review track 20260731135222.566367-1-david.lee@trailofbits.com` -> `b4 review tui` -> "review" -> "checks" patch doesn't show the Signed-off-by error in the checkpatch check view? When doing it manually, it works as expected: $ b4 am 20260731135222.566367-1-david.lee@trailofbits.com [..] $ ./scripts/checkpatch.pl -q --terse --no-summary ./20260731_david_lee_batman_adv_reject_unrepresentable_multicast_tvlv_offsets.mbx ./20260731_david_lee_batman_adv_reject_unrepresentable_multicast_tvlv_offsets.mbx:52: ERROR: Missing Signed-off-by: line by nominal patch author 'David Lee ' $ b4 --version 0.15.2 The difference comes from the "--mailback" option which b4 adds also to checkpatch. I have therefore also Cc'ed Joe Perches and Andy Whitcroft because of this suppressed error. The following change would produce the output but I have no glue and just fiddled around with the script without understanding the bigger concept (of checkpatch and why b4 uses --mailback): diff --git i/scripts/checkpatch.pl w/scripts/checkpatch.pl index 7a846a3ea1273..ccb2ec78193e0 100755 --- i/scripts/checkpatch.pl +++ w/scripts/checkpatch.pl @@ -7846,12 +7846,6 @@ sub process { exit(0); } - # In mailback mode only produce a report in the negative, for - # things that appear to be patches. - if ($mailback && ($clean == 1 || !$is_patch)) { - exit(0); - } - # This is not a patch, and we are in 'no-patch' mode so # just keep quiet. if (!$chk_patch && !$is_patch) { @@ -7902,6 +7896,12 @@ sub process { } } + # In mailback mode only produce a report in the negative, for + # things that appear to be patches. + if ($mailback && ($clean == 1 || !$is_patch)) { + exit(0); + } + print report_dump(); if ($summary && !($clean == 1 && $quiet == 1)) { print "$filename " if ($summary_file); (this is just to show the cause - not meant as anything which should be applied) Regards, Sven --nextPart3933016.MHq7AAxBmi Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part.
