While we match the "SPDX-License-Identifier" text in any context, the "file must have SDPX" validation is only performed against files that are entirely new: # Called at the end of processing a diff hunk for a file sub process_end_of_file { my $fileinfo = shift; if ($fileinfo->{action} eq "new" && !exists $fileinfo->{facts}->{sawspdx}) { ...raise error .... > Fix this by skipping over lines that start with "-" in the checkpatch > script. A new file cannot have any "-" lines present, so there isn't any bug that needs fixing AFAICT. Can you show any patch or commit where this would have made a difference to what checkpatch.pl reports ? > > Signed-off-by: Nabih Estefan > --- > scripts/checkpatch.pl | 3 ++- > 1 file changed, 2 insertions(+), 1 deletion(-) > > diff --git a/scripts/checkpatch.pl b/scripts/checkpatch.pl > index 833f20f555..c57a423f9f 100755 > --- a/scripts/checkpatch.pl > +++ b/scripts/checkpatch.pl > @@ -1813,7 +1813,8 @@ sub process { > } > > # Check SPDX-License-Identifier references a permitted license > - if ($rawline =~ m,SPDX-License-Identifier: (.*?)(\*/)?\s*$,) { > + if (($rawline =~ m,SPDX-License-Identifier: (.*?)(\*/)?\s*$,) && > + $rawline !~ /^-/) { > $fileinfo->{facts}->{sawspdx} = 1; > &checkspdx($realfile, $1); > } > -- > 2.51.0.384.g4c02a37b29-goog > With regards, Daniel -- |: https://berrange.com -o- https://www.flickr.com/photos/dberrange :| |: https://libvirt.org -o- https://fstop138.berrange.com :| |: https://entangle-photo.org -o- https://www.instagram.com/dberrange :|
