<pre>I've the following (for this bug report reduced) ruleset in nftables:
table inet filter {
set blocklistssh4 {
type ipv4_addr
}
chain blocklistssh {
}
}
Now, issuing "add rule inet filter blocklistssh ip saddr & 255.0.0.0
@blocklistssh4 drop" causes "nft -f file" to segfault. Issuing this statement
in "nft -i" reveals the following message and terminates:
BUG: invalid binop operation 6nft: evaluate.c:1515: binop_transfer_handle_lhs:
Assertion `0' failed.
Aborted
However, "add rule inet filter blocklistssh ip saddr & 255.0.0.0 {
192.168.178.0, 192.168.179.0 } drop" works.
