[Bug 1749] New: netfilter/nftables secmark support limited to 255 bytes
...Assignee: netfilter-buglog at lists.netfilter.org Reporter: joe at nall.com The kernel and nftables userspace are both limited to 255 byte (NFT_SECMARK_CTX_MAXLEN) SELinux secmark contexts. If we start with 44 characters of non category SELinux packet context system_u:object_r:http_client_packet_t:s10: we are left with 211 bytes for category bit representation. If we are using 1024 category bits, it could take 5 bytes for each bit if they are spread out c100,c123,c201,... This only gives us 42 usable category bits worst case. We have real world SELinux contexts that don't fit in 25...
