rxrpc: Fix missing locking causing hanging calls

If a call gets aborted (e.g. because kafs saw a signal) between it being
queued for connection and the I/O thread picking up the call, the abort
will be prioritised over the connection and it will be removed from
local->new_client_calls by rxrpc_disconnect_client_call() without a lock
being held. This may cause other calls on the list to disappear if a race
occurs.

Fix this by taking the client_call_lock when removing a call from whatever
list its ->wait_link happens to be on.

Merge tag 'net-next-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:
"Core & protocols:

- Large effort by Eric to lower rtnl_lock pressure and remove locks:

- Make commonly used parts of rtnetlink (address, route dumps
etc) lockless, protected by RCU instead of rtnl_lock.

- Add a netns exit callback which already holds rtnl_lock,
allowing netns exit to take rtnl_lock once in the core instead
of once for each driver / callback.

- Remove locks / serialization in the socket diag interface.

- Remove 6 calls to synchronize_rcu() while holding rtnl_lock.

- Remove the dev_base_lock, depend on RCU where necessary.

- Support busy polling on a per-epoll context basis. Poll length and
budget parameters can be set independently of system defaults.

- Introduce struct net_hotdata, to make sure read-mostly global
config variables fit in as few cache lines as possible.

- Add optional per-nexthop statistics to ease monitoring / debug of
ECMP imbalance problems.

- Support TCP_NOTSENT_LOWAT in MPTCP.

- Ensure that IPv6 temporary addresses' preferred lifetimes are long
enough, compared to other configured lifetimes, and at least 2 sec.

- Support forwarding of ICMP Error messages in IPSec, per RFC 4301.

- Add support for the independent control state machine for bonding
per IEEE 802.1AX-2008 5.4.15 in addition to the existing coupled
control state machine.

- Add "network ID" to MCTP socket APIs to support hosts with multiple
disjoint MCTP networks.

- Re-use the mono_delivery_time skbuff bit for packets which user
space wants to be sent at a specified time. Maintain the timing
information while traversing veth links, bridge etc.

- Take advantage of MSG_SPLICE_PAGES for RxRPC DATA and ACK packets.

- Simplify many places iterating over netdevs by using an xarray
instead of a hash table walk (hash table remains in place, for use
on fastpaths).

- Speed up scanning for expired routes by keeping a dedicated list.

- Speed up "generic" XDP by trying harder to avoid large allocations.

- Support attaching arbitrary metadata to netconsole messages.

Things we sprinkled into general kernel code:

- Enforce VM_IOREMAP flag and range in ioremap_page_range and
introduce VM_SPARSE kind and vm_area_[un]map_pages (used by
bpf_arena).

- Rework selftest harness to enable the use of the full range of ksft
exit code (pass, fail, skip, xfail, xpass).

Netfilter:

- Allow userspace to define a table that is exclusively owned by a
daemon (via netlink socket aliveness) without auto-removing this
table when the userspace program exits. Such table gets marked as
orphaned and a restarting management daemon can re-attach/regain
ownership.

- Speed up element insertions to nftables' concatenated-ranges set
type. Compact a few related data structures.

BPF:

- Add BPF token support for delegating a subset of BPF subsystem
functionality from privileged system-wide daemons such as systemd
through special mount options for userns-bound BPF fs to a trusted
& unprivileged application.

- Introduce bpf_arena which is sparse shared memory region between
BPF program and user space where structures inside the arena can
have pointers to other areas of the arena, and pointers work
seamlessly for both user-space programs and BPF programs.

- Introduce may_goto instruction that is a contract between the
verifier and the program. The verifier allows the program to loop
assuming it's behaving well, but reserves the right to terminate
it.

- Extend the BPF verifier to enable static subprog calls in spin lock
critical sections.

- Support registration of struct_ops types from modules which helps
projects like fuse-bpf that seeks to implement a new struct_ops
type.

- Add support for retrieval of cookies for perf/kprobe multi links.

- Support arbitrary TCP SYN cookie generation / validation in the TC
layer with BPF to allow creating SYN flood handling in BPF
firewalls.

- Add code generation to inline the bpf_kptr_xchg() helper which
improves performance when stashing/popping the allocated BPF
objects.

Wireless:

- Add SPP (signaling and payload protected) AMSDU support.

- Support wider bandwidth OFDMA, as required for EHT operation.

Driver API:

- Major overhaul of the Energy Efficient Ethernet internals to
support new link modes (2.5GE, 5GE), share more code between
drivers (especially those using phylib), and encourage more
uniform behavior. Convert and clean up drivers.

- Define an API for querying per netdev queue statistics from
drivers.

- IPSec: account in global stats for fully offloaded sessions.

- Create a concept of Ethernet PHY Packages at the Device Tree level,
to allow parameterizing the existing PHY package code.

- Enable Rx hashing (RSS) on GTP protocol fields.

Misc:

- Improvements and refactoring all over networking selftests.

- Create uniform module aliases for TC classifiers, actions, and
packet schedulers to simplify creating modprobe policies.

- Address all missing MODULE_DESCRIPTION() warnings in networking.

- Extend the Netlink descriptions in YAML to cover message
encapsulation or "Netlink polymorphism", where interpretation of
nested attributes depends on link type, classifier type or some
other "class type".

- Ethernet high-speed NICs:
- Add a new driver for Marvell's Octeon PCI Endpoint NIC VF.

KVM GUEST_MEMFD fixes for 6.8:

- Make KVM_MEM_GUEST_MEMFD mutually exclusive with KVM_MEM_READONLY to

- Update documentation for KVM_SW_PROTECTED_VM to make it abundantly
clear that such VMs are purely a development and testing vehicle, and
come with zero guarantees.

- Limit KVM_SW_PROTECTED_VM guests to the TDP MMU, as the long term plan
is to support confidential VMs with deterministic private memory (SNP
and TDX) only in the TDP MMU.

- Fix a bug in a GUEST_MEMFD negative test that resulted in false passes
when verifying that KVM_MEM_GUEST_MEMFD memslots can't be dirty logged.

Merge tag 'rxrpc-iothread-20240305' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs

David Howells says:

====================
Here are some changes to AF_RXRPC:

(1) Cache the transmission serial number of ACK and DATA packets in the
rxrpc_txbuf struct and log this in the retransmit tracepoint.

(2) Don't use atomics on rxrpc_txbuf::flags[*] and cache the intended wire
header flags there too to avoid duplication.

(3) Cache the wire checksum in rxrpc_txbuf to make it easier to create
jumbo packets in future (which will require altering the wire header
to a jumbo header and restoring it back again for retransmission).

(4) Fix the protocol names in the wire ACK trailer struct.

(5) Strip all the barriers and atomics out of the call timer tracking[*].

(6) Remove atomic handling from call->tx_transmitted and
call->acks_prev_seq[*].

(7) Don't bother resetting the DF flag after UDP packet transmission. To
change it, we now call directly into UDP code, so it's quick just to
set it every time.

(8) Merge together the DF/non-DF branches of the DATA transmission to
reduce duplication in the code.

(9) Add a kvec array into rxrpc_txbuf and start moving things over to it.
This paves the way for using page frags.

(10) Split (sub)packet preparation and timestamping out of the DATA
transmission function. This helps pave the way for future jumbo
packet generation.

(11) In rxkad, don't pick values out of the wire header stored in
rxrpc_txbuf, buf rather find them elsewhere so we can remove the wire
header from there.

(12) Move rxrpc_send_ACK() to output.c so that it can be merged with
rxrpc_send_ack_packet().

(13) Use rxrpc_txbuf::kvec[0] to access the wire header for the packet
rather than directly accessing the copy in rxrpc_txbuf. This will
allow that to be removed to a page frag.

(14) Switch from keeping the transmission buffers in rxrpc_txbuf allocated
in the slab to allocating them using page fragment allocators. There
are separate allocators for DATA packets (which persist for a while)
and control packets (which are discarded immediately).

We can then turn on MSG_SPLICE_PAGES when transmitting DATA and ACK
packets.

We can also get rid of the RCU cleanup on rxrpc_txbufs, preferring
instead to release the page frags as soon as possible.

(15) Parse received packets before handling timeouts as the former may
reset the latter.

(16) Make sure we don't retransmit DATA packets after all the packets have
been ACK'd.

(17) Differentiate traces for PING ACK transmission.

(18) Switch to keeping timeouts as ktime_t rather than a number of jiffies
as the latter is too coarse a granularity. Only set the call timer at
the end of the call event function from the aggregate of all the
timeouts, thereby reducing the number of timer calls made. In future,
it might be possible to reduce the number of timers from one per call
to one per I/O thread and to use a high-precision timer.

(19) Record RTT probes after successful transmission rather than recording
it before and then cancelling it after if unsuccessful[*]. This
allows a number of calls to get the current time to be removed.

(20) Clean up the resend algorithm as there's now no need to walk the
transmission buffer under lock[*]. DATA packets can be retransmitted
as soon as they're found rather than being queued up and transmitted
when the locked is dropped.

(21) When initially parsing a received ACK packet, extract some of the
fields from the ack info to the skbuff private data. This makes it
easier to do path MTU discovery in the future when the call to which a
PING RESPONSE ACK refers has been deallocated.

[*] Possible with the move of almost all code from softirq context to the

rxrpc: Use ktimes for call timeout tracking and set the timer lazily

Track the call timeouts as ktimes rather than jiffies as the latter's
granularity is too high and only set the timer at the end of the event

# 12a66e77 30-Jan-2024 David Howells <dhowells@redhat.com>

rxrpc: Differentiate PING ACK transmission traces.

There are three points that transmit PING ACKs and all of them use the same
trace string. Change two of them to use different strings.
