tipc: improve size validations for received domain records

2022-02-11T08:10:26+00:00

commit 9aa422ad326634b76309e8ff342c246800621216 upstream. The function tipc_mon_rcv() allows a node to receive and process domain_record structs from peer nodes to track their views of the network topology. This patch verifies that the number of members in a received domain record does not exceed the limit defined by MAX_MON_DOMAIN, something that may otherwise lead to a stack overflow. tipc_mon_rcv() is called from the function tipc_link_proto_rcv(), where we are reading a 32 bit message data length field into a uint16. To avert any risk of bit overflow, we add an extra sanity check for this in that function. We cannot see that happen with the current code, but future designers being unaware of this risk, may introduce it by allowing delivery of very large (> 64k) sk buffers from the bearer layer. This potential problem was identified by Eric Dumazet.

crypto: api - Move cryptomgr soft dependency into algapi

2022-02-11T08:10:26+00:00

commit c6ce9c5831cae515d375a01b97ae1778689acf19 upstream. The soft dependency on cryptomgr is only needed in algapi because if algapi isn't present then no algorithms can be loaded. This also fixes the case where api is built-in but algapi is built as a module as the soft dependency would otherwise get lost.

ksmbd: fix SMB 3.11 posix extension mount failure

2022-02-11T08:10:26+00:00

commit 9ca8581e79e51c57e60b3b8e3b89d816448f49fe upstream. cifs client set 4 to DataLength of create_posix context, which mean Mode variable of create_posix context is only available. So buffer validation of ksmbd should check only the size of Mode except for the size of Reserved variable.

moxart: fix potential use-after-free on remove path

commit bd2db32e7c3e35bd4d9b8bbff689434a50893546 upstream. It was reported that the mmc host structure could be accessed after it was freed in moxart_remove(), so fix this by saving the base register of the device and using it instead of the pointer dereference.

selftests: netfilter: check stateless nat udp checksum fixup

2022-02-08T17:34:14+00:00

commit aad51ca71ad83273e8826d6cfdcf53c98748d1fa upstream. Add a test that sends large udp packet (which is fragmented) via a stateless nft nat rule, i.e. 'ip saddr set 10.2.3.4' and check that the datagram is received by peer. On kernels without commit 4e1860a38637 ("netfilter: nft_payload: do not update layer 4 checksum when mangling fragments")', this will fail with: cmp: EOF on /tmp/tmp.V1q0iXJyQF which is empty -rw------- 1 root root 4096 Jan 24 22:03 /tmp/tmp.Aaqnq4rBKS -rw------- 1 root root 0 Jan 24 22:03 /tmp/tmp.V1q0iXJyQF ERROR: in and output file mismatch when checking udp with stateless nat FAIL: nftables v1.0.0 (Fearless Fosdick #2) On patched kernels, this will show: PASS: IP statless for ns2-PFp89amx Signed-off-by: Florian Westphal Signed-off-by: Pablo Neira Ayuso Signed-off-by: Greg Kroah-Hartman
