====================
Netfilter fixes for net
The following patchset contains two Netfilter fixes for net:
Patch #1 fixes CONFIG_SYSCTL=n for a patch coming in the previous PR
to move the sysctl toggle to enable SRv6 netfilter hooks from
nf_conntrack to the core, from Jianguo Wu.
Patch #2 fixes a possible pointer leak to userspace due to insufficient
validation of NFT_DATA_VALUE.
Linus found this pointer leak to userspace via zdi-disclosures@ and
forwarded the notice to Netfilter maintainers, he appears as reporter
because whoever found this issue never approached Netfilter
maintainers neither via security@ nor in private.
