This worked fine in next-20190618, but in next-20190701 I'm seeing dmesg entries at boot:
dmesg | grep -i x.509
[ 8.345699] Loading compiled-in X.509 certificates
[ 8.366137] Problem loading in-kernel X.509 certificate (-13)
[ 8.507348] cfg80211: Loading compiled-in X.509 certificates for regulatory
database
[ 8.526556] cfg80211: Problem loading in-kernel X.509 certificate (-13)
I start debugging, and discover that certs/x509_certificate_list is a
zero-length file.
I rm it, and 'make V=1 certs/system_certificates.o', which tells me:
(....)
make -f ./scripts/Makefile.headersinst obj=include/uapi
make -f ./scripts/Makefile.headersinst obj=arch/x86/include/uapi
make -f ./scripts/Makefile.build obj=certs certs/system_certificates.o

I go look at extract-cert.c, and sure enough, if the first parameter is a null
string
it just goes and creates an empty file.
The Makefile says:
quiet_cmd_extract_certs = EXTRACT_CERTS $(patsubst "%",%,$(2))
cmd_extract_certs = scripts/extract-cert $(2) $@
and damned if I know why $(2) is "". Diffed the config files from -0618 and
-0705,
not seeing anything relevant difference.
Any ideas?
