Liping Zhang 1c759b361b netfilter: nf_tables: fix oops when inserting an element into a verdict map ... commit 58c78e104d upstream. Dalegaard says: The following ruleset, when loaded with 'nft -f bad.txt' ----snip---- flush ruleset table ip inlinenat { map sourcemap { type ipv4_addr : verdict; } chain postrouting { ip saddr vmap @sourcemap accept } } add chain inlinenat test add element inlinenat sourcemap { 100.123.10.2 : jump test } ----snip---- results in a kernel oops: BUG: unable to handle kernel paging request at 0000000000001344 IP: [<ffffffffa07bf704>] nf_tables_check_loops+0x114/0x1f0 [nf_tables] [...] Call Trace: [<ffffffffa07c2aae>] ? nft_data_init+0x13e/0x1a0 [nf_tables] [<ffffffffa07c1950>] nft_validate_register_store+0x60/0xb0 [nf_tables] [<ffffffffa07c74b5>] nft_add_set_elem+0x545/0x5e0 [nf_tables] [<ffffffffa07bfdd0>] ? nft_table_lookup+0x30/0x60 [nf_tables] [<ffffffff8132c630>] ? nla_strcmp+0x40/0x50 [<ffffffffa07c766e>] nf_tables_newsetelem+0x11e/0x210 [nf_tables] [<ffffffff8132c400>] ? nla_validate+0x60/0x80 [<ffffffffa030d9b4>] nfnetlink_rcv+0x354/0x5a7 [nfnetlink] Because we forget to fill the net pointer in bind_ctx, so dereferencing it may cause kernel crash.
