rxrpc: Fix call state set to not include the SERVER_SECURING state

rxrpc: Fix call state set to not include the SERVER_SECURING state

[ Upstream commit 41b996ce83bf944de5569d6263c8dbd5513e7ed0 ]

The RXRPC_CALL_SERVER_SECURING state doesn't really belong with the other
states in the call's state set as the other states govern the call's Rx/Tx
phase transition and govern when packets can and can't be received or
transmitted. The "Securing" state doesn't actually govern the reception of
packets and would need to be split depending on whether or not we've
received the last packet yet (to mirror RECV_REQUEST/ACK_REQUEST).

The "Securing" state is more about whether or not we can start forwarding
packets to the application as recvmsg will need to decode them and the
decoding can't take place until the challenge/response exchange has
completed.

Fix this by removing the RXRPC_CALL_SERVER_SECURING state from the state
set and, instead, using a flag, RXRPC_CALL_CONN_CHALLENGING, to track
whether or not we can queue the call for reception by recvmsg() or notify
the kernel app that data is ready. In the event that we've already
received all the packets, the connection event handler will poke the app
layer in the appropriate manner.

Also there's a race whereby the app layer sees the last packet before rxrpc
has managed to end the rx phase and change the state to one amenable to
allowing a reply. Fix this by queuing the packet after calling
rxrpc_end_rx_phase().

rxrpc: Only transmit one ACK per jumbo packet received

[ Upstream commit 012b7206918dcc5a4dcf1432b3e643114c95957e ]

Only generate one ACK packet for all the subpackets in a jumbo packet. If
we would like to generate more than one ACK, we prioritise them base on
their reason code, in the order, highest first:

OutOfSeq > NoSpace > ExceedsWin > Duplicate > Requested > Delay > Idle

For the first four, we reference the lowest offending subpacket; for the
last three, the highest.

This reduces the number of ACKs we end up transmitting to one per UDP
packet transmitted to reduce network loading and packet parsing.

rxrpc: Fix congestion control algorithm

[ Upstream commit ba4e103848d3a2a28a0445e39f4a9564187efe54 ]

Make the following fixes to the congestion control algorithm:

(1) Don't vary the cwnd starting value by the size of RXRPC_TX_SMSS since
that's currently held constant - set to the size of a jumbo subpacket
payload so that we can create jumbo packets on the fly. The current
code invariably picks 3 as the starting value.

Further, the starting cwnd needs to be an even number because we ack
every other packet, so set it to 4.

(2) Don't cut ssthresh when we see an ACK come from the peer with a
receive window (rwind) less than ssthresh. ssthresh keeps track of
characteristics of the connection whereas rwind may be reduced by the
peer for any reason - and may be reduced to 0.

rxrpc: Fix counting of new acks and nacks

[ Upstream commit 41b7fa157ea1c8c3a575ca7f5f32034de9bee3ae ]

Fix the counting of new acks and nacks when parsing a packet - something
that is used in congestion control.

As the code stands, it merely notes if there are any nacks whereas what we
really should do is compare the previous SACK table to the new one,
assuming we get two successive ACK packets with nacks in them. However, we
really don't want to do that if we can avoid it as the tables might not
correspond directly as one may be shifted from the other - something that
will only get harder to deal with once extended ACK tables come into full
use (with a capacity of up to 8192).

Instead, count the number of nacks shifted out of the old SACK, the number
of nacks retained in the portion still active and the number of new acks
and nacks in the new table then calculate what we need.

Note this ends up a bit of an estimate as the Rx protocol allows acks to be
withdrawn by the receiver and packets requested to be retransmitted.

rxrpc: Defer the response to a PING ACK until we've parsed it

[ Upstream commit 1a01319feef7047aa2ba400ffa3e047776aa29ca ]

Defer the generation of a PING RESPONSE ACK in response to a PING ACK until
we've parsed the PING ACK so that we pick up any changes to the packet
queue so that we can update ackinfo.

This is also applied to an ACK generated in response to an ACK with the
REQUEST_ACK flag set.

Note that whilst the problem was added in commit 248f219cb8bc, it didn't
really matter at that point because the ACK was proposed in softirq mode
and generated asynchronously later in process context, taking the latest
values at the time. But this fix is only needed since the move to parse
incoming packets in an I/O thread rather than in softirq and generate the
ACK at point of proposal (b0346843b1076b34a0278ff601f8f287535cb064).

Merge tag 'net-next-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:
"Core:

- Add dedicated kmem_cache for typical/small skb->head, avoid having
to access struct page at kfree time, and improve memory use.

- Introduce sysctl to set default RPS configuration for new netdevs.

- Define Netlink protocol specification format which can be used to
describe messages used by each family and auto-generate parsers.
Add tools for generating kernel data structures and uAPI headers.

- Expose all net/core sysctls inside netns.

- Remove 4s sleep in netpoll if carrier is instantly detected on
boot.

- Add configurable limit of MDB entries per port, and port-vlan.

- Continue populating drop reasons throughout the stack.

- Retire a handful of legacy Qdiscs and classifiers.

Protocols:

- Support IPv4 big TCP (TSO frames larger than 64kB).

- Add IP_LOCAL_PORT_RANGE socket option, to control local port range
on socket by socket basis.

- Track and report in procfs number of MPTCP sockets used.

- Support mixing IPv4 and IPv6 flows in the in-kernel MPTCP path
manager.

- IPv6: don't check net.ipv6.route.max_size and rely on garbage
collection to free memory (similarly to IPv4).

- Support Penultimate Segment Pop (PSP) flavor in SRv6 (RFC8986).

- ICMP: add per-rate limit counters.

- Add support for user scanning requests in ieee802154.

- Remove static WEP support.

- Support minimal Wi-Fi 7 Extremely High Throughput (EHT) rate
reporting.

- WiFi 7 EHT channel puncturing support (client & AP).

BPF:

- Add a rbtree data structure following the "next-gen data structure"
precedent set by recently added linked list, that is, by using
kfunc + kptr instead of adding a new BPF map type.

- Expose XDP hints via kfuncs with initial support for RX hash and
timestamp metadata.

- Add BPF_F_NO_TUNNEL_KEY extension to bpf_skb_set_tunnel_key to
better support decap on GRE tunnel devices not operating in collect
metadata.

- Improve x86 JIT's codegen for PROBE_MEM runtime error checks.

- Remove the need for trace_printk_lock for bpf_trace_printk and
bpf_trace_vprintk helpers.

- Extend libbpf's bpf_tracing.h support for tracing arguments of
kprobes/uprobes and syscall as a special case.

- Significantly reduce the search time for module symbols by
livepatch and BPF.

- Enable cpumasks to be used as kptrs, which is useful for tracing
programs tracking which tasks end up running on which CPUs in
different time intervals.

- Add support for BPF trampoline on s390x and riscv64.

- Add capability to export the XDP features supported by the NIC.

- Add __bpf_kfunc tag for marking kernel functions as kfuncs.

- Add cgroup.memory=nobpf kernel parameter option to disable BPF
memory accounting for container environments.

Netfilter:

- Remove the CLUSTERIP target. It has been marked as obsolete for
years, and we still have WARN splats wrt races of the out-of-band
/proc interface installed by this target.

- Add 'destroy' commands to nf_tables. They are identical to the
existing 'delete' commands, but do not return an error if the
referenced object (set, chain, rule...) did not exist.

Driver API:

- Improve cpumask_local_spread() locality to help NICs set the right
IRQ affinity on AMD platforms.

- Separate C22 and C45 MDIO bus transactions more clearly.

- Introduce new DCB table to control DSCP rewrite on egress.

- Support configuration of Physical Layer Collision Avoidance (PLCA)
Reconciliation Sublayer (RS) (802.3cg-2019). Modern version of
shared medium Ethernet.

- Support for MAC Merge layer (IEEE 802.3-2018 clause 99). Allowing
preemption of low priority frames by high priority frames.

- Add support for controlling MACSec offload using netlink SET.

- Rework devlink instance refcounts to allow registration and
de-registration under the instance lock. Split the code into
multiple files, drop some of the unnecessarily granular locks and
factor out common parts of netlink operation handling.

- Add TX frame aggregation parameters (for USB drivers).

- Add a new attr TCA_EXT_WARN_MSG to report TC (offload) warning
messages with notifications for debug.

- Allow offloading of UDP NEW connections via act_ct.

- Add support for per action HW stats in TC.

- Support hardware miss to TC action (continue processing in SW from
a specific point in the action chain).

- Warn if old Wireless Extension user space interface is used with
modern cfg80211/mac80211 drivers. Do not support Wireless
Extensions for Wi-Fi 7 devices at all. Everyone should switch to
using nl80211 interface instead.

- Improve the CAN bit timing configuration. Use extack to return
error messages directly to user space, update the SJW handling,
including the definition of a new default value that will benefit
CAN-FD controllers, by increasing their oscillator tolerance.

rxrpc: Fix overproduction of wakeups to recvmsg()

Fix three cases of overproduction of wakeups:

(1) rxrpc_input_split_jumbo() conditionally notifies the app that there's
data for recvmsg() to collect if it queues some data - and then its
only caller, rxrpc_input_data(), goes and wakes up recvmsg() anyway.

Fix the rxrpc_input_data() to only do the wakeup in failure cases.

(2) If a DATA packet is received for a call by the I/O thread whilst
recvmsg() is busy draining the call's rx queue in the app thread, the
call will left on the recvmsg() queue for recvmsg() to pick up, even
though there isn't any data on it.

This can cause an unexpected recvmsg() with a 0 return and no MSG_EOR
set after the reply has been posted to a service call.

Fix this by discarding pending calls from the recvmsg() queue that
don't need servicing yet.

(3) Not-yet-completed calls get requeued after having data read from them,
even if they have no data to read.

Fix this by only requeuing them if they have data waiting on them; if
they don't, the I/O thread will requeue them when data arrives or they
fail.
