====================
Netfilter fixes for net
The following batch contains Netfilter fixes for net:
1) Allow initial x_tables table replacement without emitting an audit
log message. Delay the register message until after hooks are wired up
to avoid unnecessary unregister logs during error unwinding.
2) Fix a NULL dereference by allocating hook ops before adding the
table to the per-netns list. Use `synchronize_rcu()` during error
unwinding to ensure the table stops processing packets before
teardown. Defer audit log register message until all operations
succeed.
3) Refactor xtables to use a single `xt_unregister_table_pre_exit`
function. Eliminate code duplication by centralizing table
unregistration logic within the xtables core. ebtables cannot be
changed due to incompatibility.
4) Unregister xtables templates before module removal. This prevents
a race condition where userspace instantiates a new table after the
pernet unreg removed the current table.
5) Add `xtables_unregister_table_exit` to fully unregister netfilter
tables during module removal. Unlink the table from dying lists,
then free hook operations.
6) Implement a two-stage removal scheme for ebtables following the
x_tables pattern. Assign table->ops while holding the ebt mutex to
prevent exposing partially-filled structures.
7) Fix ebtables module initialization race. Register the template last
in table initialization functions. Prevent table instantiation before
pernet operations are available.
8) Fix a race condition in x_tables module initialization. Ensure
pernet ops are fully set up before exposing the table to userspace.
9) Fix a race condition in ebtables module initialization, similar to
previous patch.
10) Restore propagation of helper to expected connection, this is a
fix-for-recent-fix.
11) Validate that the expectation tuple and mask netlink attributes are
present when adding expectation via nfqueue, this fixes a possible
null-ptr-deref.
12) Fix possible rare memleak in the SIP helper in case helper has been
detached from conntrack entry, from Li Xiasong.
13) Fix refcount leak in nft_ct when creating custom expectation, also
from Li Xiason.
Patches 1-9 from Florian Westphal.
10) Restore propagation of helper to expected connection, this is a
fix-for-recent-fix.
11) Check that tuple and mask netlink attributes are set when creating an
expectation via nfqueue.
