2023-11-08net/sched: act_ct: Always fill offloading tuple iifidxVlad Buslov2-2/+15
Referenced commit doesn't always set iifidx when offloading the flow to hardware. Fix the following cases: - nf_conn_act_ct_ext_fill() is called before extension is created with nf_conn_act_ct_ext_add() in tcf_ct_act(). This can cause rule offload with unspecified iifidx when connection is offloaded after only single original-direction packet has been processed by tc data path. Always fill the new nf_conn_act_ct_ext instance after creating it in nf_conn_act_ct_ext_add(). - Offloading of unidirectional UDP NEW connections is now supported, but ct flow iifidx field is not updated when connection is promoted to bidirectional which can result reply-direction iifidx to be zero when refreshing the connection. Fill in the extension and update flow iifidx before calling flow_offload_refresh().

2023-11-08netfilter: nat: fix ipv6 nat redirect with mapped and scoped addressesFlorian Westphal1-1/+26
The ipv6 redirect target was derived from the ipv4 one, i.e. its identical to a 'dnat' with the first (primary) address assigned to the network interface. The code has been moved around to make it usable from nf_tables too, but its still the same as it was back when this was added in 2012. IPv6, however, has different types of addresses, if the 'wrong' address comes first the redirection does not work. In Daniels case, the addresses are: inet6 ::ffff:192 ... inet6 2a01: ... ... so the function attempts to redirect to the mapped address. Add more checks before the address is deemed correct: 1. If the packets' daddr is scoped, search for a scoped address too 2. skip tentative addresses 3. skip mapped addresses Use the first address that appears to match our needs.

2023-11-07vsock/virtio: remove socket from connected/bound list on shutdownFilippo Storniolo1-5/+11
If the same remote peer, using the same port, tries to connect to a server on a listening port more than once, the server will reject the connection, causing a "connection reset by peer" error on the remote peer. This is due to the presence of a dangling socket from a previous connection in both the connected and bound socket lists. The inconsistency of the above lists only occurs when the remote peer disconnects and the server remains active. This bug does not occur when the server socket is closed: virtio_transport_release() will eventually schedule a call to virtio_transport_do_close() and the latter will remove the socket from the bound and connected socket lists and clear the sk_buff. However, virtio_transport_do_close() will only perform the above actions if it has been scheduled, and this will not happen if the server is processing the shutdown message from a remote peer. To fix this, introduce a call to vsock_remove_sock() when the server is handling a client disconnect. This is to remove the socket from the bound and connected socket lists without clearing the sk_buff.

Clang warns (or errors with CONFIG_WERROR=y) when CONFIG_TCP_AO is set: net/ipv4/tcp_output.c:663:2: error: label at end of compound statement is a C23 extension [-Werror,-Wc23-extensions] 663 | } | ^ 1 error generated. On earlier releases (such as clang-11, the current minimum supported version for building the kernel) that do not support C23, this was a hard error unconditionally: net/ipv4/tcp_output.c:663:2: error: expected statement } ^ 1 error generated. While adding a semicolon after the label would resolve this, it is more in line with the kernel as a whole to refactor this block into a standalone function, which means the goto a label construct can just be replaced with a return statement. Do so to resolve the warning.

2023-11-06net/smc: allow cdc msg send rather than drop it with NULL sndbuf_descD. Wythe1-5/+4
This patch re-fix the issues mentioned by commit 22a825c541d7 ("net/smc: fix NULL sndbuf_desc in smc_cdc_tx_handler()"). Blocking sending message do solve the issues though, but it also prevents the peer to receive the final message. Besides, in logic, whether the sndbuf_desc is NULL or not have no impact on the processing of cdc message sending. Hence that, this patch allows the cdc message sending but to check the sndbuf_desc with care in smc_cdc_tx_handler().

2023-11-06tcp: Fix SYN option room calculation for TCP-AO.Kuniyuki Iwashima1-2/+3
When building SYN packet in tcp_syn_options(), MSS, TS, WS, and SACKPERM are used without checking the remaining bytes in the options area. To keep that logic as is, we limit the TCP-AO MAC length in tcp_ao_parse_crypto(). Currently, the limit is calculated as below. MAX_TCP_OPTION_SPACE - TCPOLEN_TSTAMP_ALIGNED - TCPOLEN_WSCALE_ALIGNED - TCPOLEN_SACKPERM_ALIGNED This looks confusing as (1) we pack SACKPERM into the leading 2-bytes of the aligned 12-bytes of TS and (2) TCPOLEN_MSS_ALIGNED is not used. Fortunately, the calculated limit is not wrong as TCPOLEN_SACKPERM_ALIGNED and TCPOLEN_MSS_ALIGNED are the same value. However, we should use the proper constant in the formula. MAX_TCP_OPTION_SPACE - TCPOLEN_MSS_ALIGNED - TCPOLEN_TSTAMP_ALIGNED - TCPOLEN_WSCALE_ALIGNED Fixes: 4954f17ddefc ("net/tcp: Introduce TCP_AO setsockopt()s") Signed-off-by: Kuniyuki Iwashima <kuniyu@amazon.com> Reviewed-by: Dmitry Safonov <dima@arista.com> Signed-off-by: David S.

2023-11-02dccp/tcp: Call security_inet_conn_request() after setting IPv6 addresses.Kuniyuki Iwashima2-6/+7
Initially, commit 4237c75c0a35 ("[MLSXFRM]: Auto-labeling of child sockets") introduced security_inet_conn_request() in some functions where reqsk is allocated. The hook is added just after the allocation, so reqsk's IPv6 remote address was not initialised then. However, SELinux/Smack started to read it in netlbl_req_setattr() after commit e1adea927080 ("calipso: Allow request sockets to be relabelled by the lsm."). Commit 284904aa7946 ("lsm: Relocate the IPv4 security_inet_conn_request() hooks") fixed that kind of issue only in TCPv4 because IPv6 labeling was not supported at that time. Finally, the same issue was introduced again in IPv6. Let's apply the same fix on DCCPv6 and TCPv6. Fixes: e1adea927080 ("calipso: Allow request sockets to be relabelled by the lsm.")
