netfilter: nf_tables: avoid chain re-validation if possible
Hamza Mahfooz reports cpu soft lock-ups in nft_chain_validate(): watchdog: BUG: soft lockup - CPU#1 stuck for 27s! [iptables-nft-re:37547] [..] RIP: 0010:nft_chain_validate+0xcb/0x110 [nf_tables] [..] nft_immediate_validate+0x36/0x50 [nf_tables] nft_chain_validate+0xc9/0x110 [nf_tables] nft_immediate_validate+0x36/0x50 [nf_tables] nft_chain_validate+0xc9/0x110 [nf_tables] nft_immediate_validate+0x36/0x50 [nf_tables] nft_chain_validate+0xc9/0x110 [nf_tables] nft_immediate_validate+0x36/0x50 [nf_tables] nft_chain_validate+0xc9/0x110 [nf_tables] nft_immediate_validate+0x36/0x50 [nf_tables] nft_chain_validate+0xc9/0x110 [nf_tables] nft_immediate_validate+0x36/0x50 [nf_tables] nft_chain_validate+0xc9/0x110 [nf_tables] nft_table_validate+0x6b/0xb0 [nf_tables] nf_tables_validate+0x8b/0xa0 [nf_tables] nf_tables_commit+0x1df/0x1eb0 [nf_tables] [..] Currently nf_tables will traverse the entire table (chain graph), starting from the entry points (base chains), exploring all possible paths (chain jumps). But there are cases where we could avoid revalidation. Consider: 1 input -> j2 -> j3 2 input -> j2 -> j3 3 input -> j1 -> j2 -> j3 Then the second rule does not need to revalidate j2, and, by extension j3, because this was already checked during validation of the first rule. We need to validate it only for rule 3. This is needed because chain loop detection also ensures we do not exceed the jump stack: Just because we know that j2 is cycle free, its last jump might now exceed the allowed stack size. We also need to update all reachable chains with the new largest observed call depth. Care has to be taken to revalidate even if the chain depth won't be an issue: chain validation also ensures that expressions are not called from invalid base chains. For example, the masquerade expression can only be called from NAT postrouting base chains. Therefore we also need to keep record of the base chain context (type, hooknum) and revalidate if the chain becomes reachable from a different hook location.

inet: frags: flush pending skbs in fqdir_pre_exit()
We have been seeing occasional deadlocks on pernet_ops_rwsem since
September in NIPA. The stuck task was usually modprobe (often loading
a driver like ipvlan), trying to take the lock as a Writer.
lockdep does not track readers for rwsems so the read wasn't obvious
from the reports.
On closer inspection the Reader holding the lock was conntrack looping
forever in nf_conntrack_cleanup_net_list(). Based on past experience
with occasional NIPA crashes I looked thru the tests which run before
the crash and noticed that the crash follows ip_defrag.sh. An immediate
red flag. Scouring thru (de)fragmentation queues reveals skbs sitting
around, holding conntrack references.
The problem is that since conntrack depends on nf_defrag_ipv6,
nf_defrag_ipv6 will load first. Since nf_defrag_ipv6 loads first its
netns exit hooks run _after_ conntrack's netns exit hook.
Flush all fragment queue SKBs during fqdir_pre_exit() to release
conntrack references before conntrack cleanup runs. Also flush
the queues in timer expiry handlers when they discover fqdir->dead
is set, in case packet sneaks in while we're running the pre_exit
flush.
The commit under Fixes is not exactly the culprit, but I think
previously the timer firing would eventually unblock the spinning
conntrack.
Fixes:

net: dsa: add simple HSR offload helpers
It turns out that HSR offloads are so fine-grained that many DSA switches can do a small part even though they weren't specifically designed for the protocols supported by that driver (HSR and PRP). Specifically NETIF_F_HW_HSR_DUP - it is simple packet duplication on transmit, towards all (aka 2) ports members of the HSR device. For many DSA switches, we know how to duplicate a packet, even though we never typically use that feature. The transmit port mask from the tagging protocol can have multiple bits set, and the switch should send the packet once to every port with a bit set from that mask. Nonetheless, not all tagging protocols are like this, and sometimes the port is a single numeric value rather than a bit mask. For that reason, and also because switches can sometimes change tagging protocols for different ones, we need to make HSR offload helpers opt-in. For devices that can do nothing else HSR-specific, we introduce dsa_port_simple_hsr_join() and dsa_port_simple_hsr_leave(). These functions monitor when two user ports of the same switch are part of the same HSR device, and when that condition is true, they toggle the NETIF_F_HW_HSR_DUP feature flag of both net devices. Normally only dsa_port_simple_hsr_join() and dsa_port_simple_hsr_leave() are needed. The dsa_port_simple_hsr_validate() helper is just to see what kind of configuration could be offloadable using the generic helpers. This is used by switch drivers which are not currently using the right tagging protocol to offload this HSR ring, but could in principle offload it after changing the tagger.

Netfilter updates for net-next
The following batch contains Netfilter updates for net-next:
0) Add sanity check for maximum encapsulations in bridge vlan,
reported by the new AI robot.
1) Move the flowtable path discovery code to its own file, the
nft_flow_offload.c mixes the nf_tables evaluation with the path
discovery logic, just split this in two for clarity.
2) Consolidate flowtable xmit path by using dev_queue_xmit() and the
real device behind the layer 2 vlan/pppoe device. This allows to
inline encapsulation. After this update, hw_ifidx can be removed
since both ifidx and hw_ifidx now point to the same device.
3) Support for IPIP encapsulation in the flowtable, extend selftest
to cover for this new layer 3 offload, from Lorenzo Bianconi.
4) Push down the skb into the conncount API to fix duplicates in the
conncount list for packets with non-confirmed conntrack entries,
this is due to an optimization introduced in

netfilter: flowtable: Add IPIP rx sw acceleration
Introduce sw acceleration for rx path of IPIP tunnels relying on the
netfilter flowtable infrastructure. Subsequent patches will add sw
acceleration for IPIP tunnels tx path.
This series introduces basic infrastructure to accelerate other tunnel
types (e.g. IP6IP6).
IPIP rx sw acceleration can be tested running the following scenario where
the traffic is forwarded between two NICs (eth0 and eth1) and an IPIP
tunnel is used to access a remote site (using eth1 as the underlay device):
ETH0 -- TUN0 <==> ETH1 -- [IP network] -- TUN1 (192.168.100.2)
$ip addr show
6: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
link/ether 00:00:22:33:11:55 brd ff:ff:ff:ff:ff:ff
inet 192.168.0.2/24 scope global eth0
valid_lft forever preferred_lft forever
7: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
link/ether 00:11:22:33:11:55 brd ff:ff:ff:ff:ff:ff

192.168.1.0/24 dev eth1 proto kernel scope link src 192.168.1.1
192.168.100.0/24 dev tun0 proto kernel scope link src 192.168.100.1

flowtable ft {
hook ingress priority filter
devices = { eth0, eth1 }
}
chain forward {
type filter hook forward priority filter; policy accept;
meta l4proto { tcp, udp } flow add @ft
}
}
Reproducing the scenario described above using veths I got the following
results:
- TCP stream received from the IPIP tunnel:
- net-next: (baseline) ~ 71Gbps
- net-next + IPIP flowtbale support: ~101Gbps

netfilter: flowtable: consolidate xmit path
Use dev_queue_xmit() for the XMIT_NEIGH case. Store the interface index of the real device behind the vlan/pppoe device, this introduces an extra lookup for the real device in the xmit path because rt->dst.dev provides the vlan/pppoe device. XMIT_NEIGH now looks more similar to XMIT_DIRECT but the check for stale dst and the neighbour lookup still remain in place which is convenient to deal with network topology changes. Note that nft_flow_route() needs to relax the check for _XMIT_NEIGH so the existing basic xfrm offload (which only works in one direction) does not break.

sk->sk_timer has been used for TCP keepalives. Keepalive timers are not in fast path, we want to use sk->sk_timer storage for retransmit timers, for better cache locality. Create icsk->icsk_keepalive_timer and change keepalive code to no longer use sk->sk_timer. Added space is reclaimed in the following patch. This includes changes to MPTCP, which was also using sk_timer. Alias icsk->mptcp_tout_timer and icsk->icsk_keepalive_timer for inet_sk_diag_fill() sake.

net_sched: add qdisc_dequeue_drop() helper
Some qdisc like cake, codel, fq_codel might drop packets in their dequeue() method. This is currently problematic because dequeue() runs with the qdisc spinlock held. Freeing skbs can be extremely expensive. Add qdisc_dequeue_drop() method and a new TCQ_F_DEQUEUE_DROPS so that these qdiscs can opt-in to defer the skb frees after the socket spinlock is released. TCQ_F_DEQUEUE_DROPS is an attempt to not penalize other qdiscs with an extra cache line miss.

net_sched: add Qdisc_read_mostly and Qdisc_write groups
It is possible to reorg Qdisc to avoid always dirtying 2 cache lines in
fast path by reducing this to a single dirtied cache line.
In current layout, we change only four/six fields in the first cache line:
- q.spinlock
- q.qlen
- bstats.bytes
- bstats.packets
- some Qdisc also change q.next/q.prev
In the second cache line we change in the fast path:
- running
- state
- qstats.backlog
/* --- cacheline 2 boundary (128 bytes) --- */
struct sk_buff_head gso_skb __attribute__((__aligned__(64))); /* 0x80 0x18 */
struct qdisc_skb_head q; /* 0x98 0x18 */
struct gnet_stats_basic_sync bstats __attribute__((__aligned__(16))); /* 0xb0 0x10 */
/* --- cacheline 3 boundary (192 bytes) --- */
struct gnet_stats_queue qstats; /* 0xc0 0x14 */
bool running; /* 0xd4 0x1 */
/* XXX 3 bytes hole, try to pack */
unsigned long state; /* 0xd8 0x8 */
struct Qdisc * next_sched; /* 0xe0 0x8 */
struct sk_buff_head skb_bad_txq; /* 0xe8 0x18 */
/* --- cacheline 4 boundary (256 bytes) --- */
Reorganize things to have a first cache line mostly read,
then a mostly written one.
This gives a ~3% increase of performance under tx stress.
Note that there is an additional hole because @qstats now spans over a third cache line.

devlink: support default values for param-get and param-set
Support querying and resetting to default param values. Introduce two new devlink netlink attrs: DEVLINK_ATTR_PARAM_VALUE_DEFAULT and DEVLINK_ATTR_PARAM_RESET_DEFAULT. The former is used to contain an optional parameter value inside of the param_value nested attribute. The latter is used in param-set requests from userspace to indicate that the driver should reset the param to its default value. To implement this, two new functions are added to the devlink driver api: devlink_param::get_default() and devlink_param::reset_default(). These callbacks allow drivers to implement default param actions for runtime and permanent cmodes. For driverinit params, the core latches the last value set by a driver via devl_param_driverinit_value_set(), and uses that as the default value for a param. Because default parameter values are optional, it would be impossible to discern whether or not a param of type bool has default value of false or not provided if the default value is encoded using a netlink flag type. For this reason, when a DEVLINK_PARAM_TYPE_BOOL has an associated default value, the default value is encoded using a u8 type.

net: mana: Add standard counter rx_missed_errors
Report standard counter stats->rx_missed_errors using hc_rx_discards_no_wqe from the hardware. Add a global workqueue to periodically run mana_query_gf_stats every 2 seconds to get the latest info in eth_stats and define a driver capability flag to notify hardware of the periodic queries. To avoid repeated failures and log flooding, the workqueue is not rescheduled if mana_query_gf_stats fails on HWC timeout error and the stats are reset to 0. Other errors are transient which will not need a VF reset for recovery.

net: mana: Move hardware counter stats from per-port to per-VF context
Move hardware counter (HC) statistics from mana_port_context to mana_context to enable sharing stats across multiple network ports on the same MANA VF. Previously, each network port queried hardware counters independently using MANA_QUERY_GF_STAT command (GF = Generic Function stats from GDMA hardware), resulting in redundant queries when multiple ports existed on the same device. Isolate hardware counter stats by introducing mana_ethtool_hc_stats in mana_context and update the code to ensure all stats are properly reported via ethtool -S <interface>, maintaining consistency with previous behavior.

memcg: net: track network throttling due to memcg memory pressure
The kernel can throttle network sockets if the memory cgroup associated with the corresponding socket is under memory pressure. The throttling actions include clamping the transmit window, failing to expand receive or send buffers, aggressively prune out-of-order receive queue, FIN deferred to a retransmitted packet and more. Let's add memcg metric to track such throttling actions. At the moment memcg memory pressure is defined through vmpressure and in future it may be defined using PSI or we may add more flexible way for the users to define memory pressure, maybe through ebpf. However the potential throttling actions will remain the same, so this newly introduced metric will continue to track throttling actions irrespective of how memcg memory pressure is defined.
