Hello,
while testing merge window snapshots, I noticed that after commit
b8c96a6b466c ("certs: simplify $(srctree)/ handling and remove
config_filename macro"), build with
CONFIG_MODULE_SIG=y
CONFIG_MODULE_SIG_FORCE=n
CONFIG_MODULE_SIG_ALL=n
CONFIG_MODULE_SIG_KEY=""
(as suggested in Documentation/kbuild/reproducible-builds.rst, section
"Module signing") fails to build as make executes scripts/extract-cert
with only one argument (the unquoted empty string has no effect):
...
certs/extract-cert certs/signing_key.x509
Usage: extract-cert <source> <dest>
make[2]: *** [/home/mike/work/git/kernel-upstream/certs/Makefile:78: certs/signing_key.x509] Error 2
make[1]: *** [/home/mike/work/git/kernel-upstream/Makefile:1831: certs] Error 2
make[1]: Leaving directory '/srv/ram/kobj'
make: *** [Makefile:219: __sub-make] Error 2
Should this be considered a bug or is there a different recommended way
to get reproducible builds now?
