Subject: segtree: set on EXPR_F_KERNEL flag for catchall elements in the cache
X-Git-Tag: v1.1.0~13
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=dc6950a80110d6e6f63bd6f5c308d202db698f46;p=thirdparty%2Fnftables.git

segtree: set on EXPR_F_KERNEL flag for catchall elements in the cache

Catchall set element deletion requires this flag to be set on,
otherwise it bogusly reports that such element does not exist
in the set.

Fixes: f1cc44edb218 ("src: add EXPR_F_KERNEL to identify expression in the kernel")
