Hi, we are having a problem loading nf_conntrack on linux-next: # modprobe nf_conntrack modprobe: ERROR: could not insert 'nf_conntrack': Unknown symbol in module, or unknown parameter (see dmesg) modprobe: ERROR: Error running install command '/sbin/modprobe --ignore-install nf_conntrack && /sbin/sysctl --quiet --pattern 'net[.]netfilter[.]nf_conntrack.*' --system' for module nf_conntrack: retcode 1 modprobe: ERROR: could not insert 'nf_conntrack': Invalid argument # dmesg [ 3728.188969] missing module BTF, cannot register kfuncs [ 3748.208674] missing module BTF, cannot register kfuncs [ 3748.567123] missing module BTF, cannot register kfuncs [ 3873.597276] missing module BTF, cannot register kfuncs [ 3874.017125] missing module BTF, cannot register kfuncs [ 3882.637097] missing module BTF, cannot register kfuncs [ 3883.507213] missing module BTF, cannot register kfuncs [ 3883.876878] missing module BTF, cannot register kfuncs # zgrep BTF /proc/config.gz CONFIG_DEBUG_INFO_BTF=y CONFIG_PAHOLE_HAS_SPLIT_BTF=y CONFIG_DEBUG_INFO_BTF_MODULES=y It seems that nf_conntrack.ko is missing a .BTF section which is present in debuginfo within /usr/lib/debug/lib/modules/*/kernel/net/netfilter/nf_conntrack.ko.debug instead. Am i correct in assuming that this is not supported (yet) ? We use pahole 1.22 and build linux-next on Fedora 35 as a set of custom packages. Architecture is s390x. Thanks Regards Alex
