2022-10-25thermal: Validate new state in cur_state_store()Viresh Kumar1-0/+1
In cur_state_store(), the new state of the cooling device is received from user-space and is not validated by the thermal core but the same is left for the individual drivers to take care of. Apart from duplicating the code it leaves possibility for introducing bugs where a driver may not do it right. Lets make the thermal core check the new state itself and store the max value in the cooling device structure.

2022-10-25netfilter: nft_inner: support for inner tunnel header matchingPablo Neira Ayuso3-0/+55
This new expression allows you to match on the inner headers that are encapsulated by any of the existing tunneling protocols. This expression parses the inner packet to set the link, network and transport offsets, so the existing expressions (with a few updates) can be reused to match on the inner headers. The inner expression supports for different tunnel combinations such as: - ethernet frame over IPv4/IPv6 packet, eg. VxLAN. - IPv4/IPv6 packet over IPv4/IPv6 packet, eg. IPIP. - IPv4/IPv6 packet over IPv4/IPv6 + transport header, eg. GRE. - transport header (ESP or SCTP) over transport header (usually UDP) The following fields are used to describe the tunnel protocol: - flags, which describe how to parse the inner headers: NFT_PAYLOAD_CTX_INNER_TUN, the tunnel provides its own header. NFT_PAYLOAD_CTX_INNER_ETHER, the ethernet frame is available as inner header. NFT_PAYLOAD_CTX_INNER_NH, the network header is available as inner header. NFT_PAYLOAD_CTX_INNER_TH, the transport header is available as inner header. For example, VxLAN sets on all of these flags. While GRE only sets on NFT_PAYLOAD_CTX_INNER_NH and NFT_PAYLOAD_CTX_INNER_TH. Then, ESP over UDP only sets on NFT_PAYLOAD_CTX_INNER_TH. The tunnel description is composed of the following attributes: - header size: in case the tunnel comes with its own header, eg. VxLAN. - type: this provides a hint to userspace on how to delinearize the rule. This is useful for VxLAN and Geneve since they run over UDP, since transport does not provide a hint. This is also useful in case hardware offload is ever supported. The type is not currently interpreted by the kernel. - expression: currently only payload supported. Follow up patch adds also inner meta support which is required by autogenerated dependencies. The exthdr expression should be supported too at some point. There is a new inner_ops operation that needs to be set on to allow to use an existing expression from the inner expression. This patch adds a new NFT_PAYLOAD_TUN_HEADER base which allows to match on the tunnel header fields, eg. vxlan vni. The payload expression is embedded into nft_inner private area and this private data area is passed to the payload inner eval function via direct call.

2022-10-25soreuseport: Fix socket selection for SO_INCOMING_CPU.Kuniyuki Iwashima1-0/+2
Kazuho Oku reported that setsockopt(SO_INCOMING_CPU) does not work with setsockopt(SO_REUSEPORT) since v4.6. With the combination of SO_REUSEPORT and SO_INCOMING_CPU, we could build a highly efficient server application. setsockopt(SO_INCOMING_CPU) associates a CPU with a TCP listener or UDP socket, and then incoming packets processed on the CPU will likely be distributed to the socket. Technically, a socket could even receive packets handled on another CPU if no sockets in the reuseport group have the same CPU receiving the flow. The logic exists in compute_score() so that a socket will get a higher score if it has the same CPU with the flow. However, the score gets ignored after the blamed two commits, which introduced a faster socket selection algorithm for SO_REUSEPORT. This patch introduces a counter of sockets with SO_INCOMING_CPU in a reuseport group to check if we should iterate all sockets to find a proper one. We increment the counter when * calling listen() if the socket has SO_INCOMING_CPU and SO_REUSEPORT * enabling SO_INCOMING_CPU if the socket is in a reuseport group Also, we decrement it when * detaching a socket out of the group to apply SO_INCOMING_CPU to migrated TCP requests * disabling SO_INCOMING_CPU if the socket is in a reuseport group When the counter reaches 0, we can get back to the O(1) selection algorithm. The overall changes are negligible for the non-SO_INCOMING_CPU case, and the only notable thing is that we have to update sk_incomnig_cpu under reuseport_lock. Otherwise, the race prevents transitioning to the O(n) algorithm and results in the wrong socket selection. cpu1 (setsockopt) cpu2 (listen) +-----------------+ +-------------+ lock_sock(sk1) lock_sock(sk2) reuseport_update_incoming_cpu(sk1, val) . | /* set CPU as 0 */ |- WRITE_ONCE(sk1->incoming_cpu, val) | | spin_lock_bh(&reuseport_lock) | reuseport_grow(sk2, reuse) | . | |- more_socks_size = reuse->max_socks * 2U; | |- if (more_socks_size > U16_MAX && | | reuse->num_closed_socks) | | . | | |- RCU_INIT_POINTER(sk1->sk_reuseport_cb, NULL); | | `- __reuseport_detach_closed_sock(sk1, reuse) | | . | | `- reuseport_put_incoming_cpu(sk1, reuse) | | . | | | /* Read shutdown()ed sk1's sk_incoming_cpu | | | * without lock_sock(). | | | */ | | `- if (sk1->sk_incoming_cpu >= 0) | | . | | | /* decrement not-yet-incremented | | | * count, which is never incremented. | | | */ | | `- __reuseport_put_incoming_cpu(reuse); | | | `- spin_lock_bh(&reuseport_lock) | |- spin_lock_bh(&reuseport_lock) | |- reuse = rcu_dereference_protected(sk1->sk_reuseport_cb, ...) |- if (!reuse) | . | | /* Cannot increment reuse->incoming_cpu. */ | `- goto out; | `- spin_unlock_bh(&reuseport_lock) Fixes: e32ea7e74727 ("soreuseport: fast reuseport UDP socket selection") Fixes: c125e80b8868 ("soreuseport: fast reuseport TCP socket selection") Reported-by: Kazuho Oku <[email protected]> Signed-off-by: Kuniyuki Iwashima <[email protected]> Signed-off-by: Paolo Abeni <[email protected]>
2022-10-25act_skbedit: skbedit queue mapping for receive queueAmritha Nambiar3-0/+32
Add support for skbedit queue mapping action on receive side. This is supported only in hardware, so the skip_sw flag is enforced. This enables offloading filters for receive queue selection in the hardware using the skbedit action. Traffic arrives on the Rx queue requested in the skbedit action parameter. A new tc action flag TCA_ACT_FLAGS_AT_INGRESS is introduced to identify the traffic direction the action queue_mapping is requested on during filter addition. This is used to disallow offloading the skbedit queue mapping action on transmit side. Example: $tc filter add dev $IFACE ingress protocol ip flower dst_ip $DST_IP\ action skbedit queue_mapping $rxq_id skip_sw Reviewed-by: Sridhar Samudrala <[email protected]> Signed-off-by: Amritha Nambiar <[email protected]> Signed-off-by: Paolo Abeni <[email protected]>

2022-10-24genetlink: piggy back on resv_op to default to a reject policyJakub Kicinski1-1/+9
To keep backward compatibility we used to leave attribute parsing to the family if no policy is specified. This becomes tedious as we move to more strict validation. Families must define reject all policies if they don't want any attributes accepted. Piggy back on the resv_start_op field as the switchover point. AFAICT only ethtool has added new commands since the resv_start_op was defined, and it has per-op policies so this should be a no-op. Nonetheless the patch should still go into v6.1 for consistency.

2022-10-24zstd: import usptream v1.5.2Nick Terrell1-178/+297
Updates the kernel's zstd library to v1.5.2, the latest zstd release. The upstream tag it is updated to is `v1.5.2-kernel`, which contains several cherry-picked commits on top of the v1.5.2 release which are required for the kernel update. I will create this tag once the PR is ready to merge, until then reference the temporary upstream branch `v1.5.2-kernel-cherrypicks`. I plan to submit this patch as part of the v6.2 merge window. I've done basic build testing & testing on x86-64, i386, and aarch64. I'm merging these patches into my `zstd-next` branch, which is pulled into `linux-next` for further testing. I've benchmarked BtrFS with zstd compression on a x86-64 machine, and saw these results. Decompression speed is a small win across the board. The lower compression levels 1-4 see both compression speed and compression ratio wins. The higher compression levels see a small compression speed loss and about neutral ratio. I expect the lower compression levels to be used much more heavily than the high compression levels, so this should be a net win.

2022-10-24net-memcg: avoid stalls when under memory pressureJakub Kicinski1-1/+1
As Shakeel explains the commit under Fixes had the unintended side-effect of no longer pre-loading the cached memory allowance. Even tho we previously dropped the first packet received when over memory limit - the consecutive ones would get thru by using the cache. The charging was happening in batches of 128kB, so we'd let in 128kB (truesize) worth of packets per one drop. After the change we no longer force charge, there will be no cache filling side effects. This causes significant drops and connection stalls for workloads which use a lot of page cache, since we can't reclaim page cache under GFP_NOWAIT. Some of the latency can be recovered by improving SACK reneg handling but nowhere near enough to get back to the pre-5.15 performance (the application I'm experimenting with still sees 5-10x worst latency). Apply the suggested workaround of using GFP_ATOMIC. We will now be more permissive than previously as we'll drop _no_ packets in softirq when under pressure. But I can't think of any good and simple way to address that within networking.

2022-10-24net: add a refcount tracker for kernel socketsEric Dumazet1-8/+22
Commit ffa84b5ffb37 ("net: add netns refcount tracker to struct sock") added a tracker to sockets, but did not track kernel sockets. We still have syzbot reports hinting about netns being destroyed while some kernel TCP sockets had not been dismantled. This patch tracks kernel sockets, and adds a ref_tracker_dir_print() call to net_free() right before the netns is freed. Normally, each layer is responsible for properly releasing its kernel sockets before last call to net_free(). This debugging facility is enabled with CONFIG_NET_NS_REFCNT_TRACKER=y Signed-off-by: Eric Dumazet <[email protected]> Reviewed-by: Kuniyuki Iwashima <[email protected]> Tested-by: Kuniyuki Iwashima <[email protected]> Signed-off-by: David S.

2022-10-24udp: track the forward memory release threshold in an hot cachelinePaolo Abeni2-0/+12
When the receiver process and the BH runs on different cores, udp_rmem_release() experience a cache miss while accessing sk_rcvbuf, as the latter shares the same cacheline with sk_forward_alloc, written by the BH. With this patch, UDP tracks the rcvbuf value and its update via custom SOL_SOCKET socket options, and copies the forward memory threshold value used by udp_rmem_release() in a different cacheline, already accessed by the above function and uncontended. Since the UDP socket init operation grown a bit, factor out the common code between v4 and v6 in a shared helper. Overall the above give a 10% peek throughput increase under UDP flood.

2022-10-24net: introduce and use custom sockopt socket flagPaolo Abeni1-0/+1
We will soon introduce custom setsockopt for UDP sockets, too. Instead of doing even more complex arbitrary checks inside sock_use_custom_sol_socket(), add a new socket flag and set it for the relevant socket types (currently only MPTCP).

2022-10-24efi: random: reduce seed size to 32 bytesArd Biesheuvel1-1/+1
We no longer need at least 64 bytes of random seed to permit the early crng init to complete. The RNG is now based on Blake2s, so reduce the EFI seed size to the Blake2s hash size, which is sufficient for our purposes. While at it, drop the READ_ONCE(), which was supposed to prevent size from being evaluated after seed was unmapped. However, this cannot actually happen, so READ_ONCE() is unnecessary here.
