net: SO_RCVMARK socket option for SO_MARK with recvmsg()

2022-04-28T20:08:15+00:00

Adding a new socket option, SO_RCVMARK, to indicate that SO_MARK should be included in the ancillary data returned by recvmsg(). Renamed the sock_recv_ts_and_drops() function to sock_recv_cmsgs().

net: remove noblock parameter from recvmsg() entities

2022-04-12T13:00:25+00:00

The internal recvmsg() functions have two parameters 'flags' and 'noblock' that were merged inside skb_recv_datagram(). As a follow up patch to commit f4b41f062c42 ("net: remove noblock parameter from skb_recv_datagram()") this patch removes the separate 'noblock' parameter for recvmsg(). Analogue to the referenced patch for skb_recv_datagram() the 'flags' and 'noblock' parameters are unnecessarily split up with e.g. err = sk->sk_prot->recvmsg(sk, msg, size, flags & MSG_DONTWAIT, flags & ~MSG_DONTWAIT, &addr_len); or in err = INDIRECT_CALL_2(sk->sk_prot->recvmsg, tcp_recvmsg, udp_recvmsg, sk, msg, size, flags & MSG_DONTWAIT, flags & ~MSG_DONTWAIT, &addr_len); instead of simply using only flags all the time and check for MSG_DONTWAIT where needed (to preserve for the formerly separated no(n)block condition).

net: remove noblock parameter from skb_recv_datagram()

2022-04-06T12:45:26+00:00

skb_recv_datagram() has two parameters 'flags' and 'noblock' that are merged inside skb_recv_datagram() by 'flags | (noblock ? MSG_DONTWAIT : 0)' As 'flags' may contain MSG_DONTWAIT as value most callers split the 'flags' into 'flags' and 'noblock' with finally obsolete bit operations like this: skb_recv_datagram(sk, flags & ~MSG_DONTWAIT, flags & MSG_DONTWAIT, &rc); And this is not even done consistently with the 'flags' parameter. This patch removes the obsolete and costly splitting into two parameters and only performs bit operations when really needed on the caller side. One missing conversion thankfully reported by kernel test robot. I missed to enable kunit tests to build the mctp code.

net: ipv6: Handle delivery_time in ipv6 defrag

2022-03-03T14:38:48+00:00

A latter patch will postpone the delivery_time clearing until the stack knows the skb is being delivered locally (i.e. calling skb_clear_delivery_time() at ip_local_deliver_finish() for IPv4 and at ip6_input_finish() for IPv6). That will allow other kernel forwarding path (e.g. ip[6]_forward) to keep the delivery_time also. A very similar IPv6 defrag codes have been duplicated in multiple places: regular IPv6, nf_conntrack, and 6lowpan. Unlike the IPv4 defrag which is done before ip_local_deliver_finish(), the regular IPv6 defrag is done after ip6_input_finish(). Thus, no change should be needed in the regular IPv6 defrag logic because skb_clear_delivery_time() should have been called. 6lowpan also does not need special handling on delivery_time because it is a non-inet packet_type. However, cf_conntrack has a case in NF_INET_PRE_ROUTING that needs to do the IPv6 defrag earlier. Thus, it needs to save the mono_delivery_time bit in the inet_frag_queue which is similar to how it is handled in the previous patch for the IPv4 defrag. This patch chooses to do it consistently and stores the mono_delivery_time in the inet_frag_queue for all cases such that it will be easier for the future refactoring effort on the IPv6 reasm code.

Stefan Schmidt says: ==================== pull-request: ieee802154-next 2022-02-10 An update from ieee802154 for your *net-next* tree. There is more ongoing in ieee802154 than usual. This will be the first pull request for this cycle, but I expect one more. Depending on review and rework times. Pavel Skripkin ported the atusb driver over to the new USB api to avoid unint problems as well as making use of the modern api without kmalloc() needs in he driver. Miquel Raynal landed some changes to ensure proper frame checksum checking with hwsim, documenting our use of wake and stop_queue and eliding a magic value by using the proper define. David Girault documented the address struct used in ieee802154. ==================== Signed-off-by: David S. Miller
