tcp_bpf: Charge receive socket buffer in bpf_tcp_ingress()
When bpf_tcp_ingress() is called, the skmsg is being redirected to the
ingress of the destination socket. Therefore, we should charge its
receive socket buffer, instead of sending socket buffer.
Because sk_rmem_schedule() tests pfmemalloc of skb, we need to
introduce a wrapper and call it for skmsg.

Bluetooth: SCO: Add support for 16 bits transparent voice setting
The voice setting is used by sco_connect() or sco_conn_defer_accept()
after being set by sco_sock_setsockopt().
The PCM part of the voice setting is used for offload mode through PCM
chipset port.
This commits add support for mSBC 16 bits offloading, i.e. audio data
not transported over HCI.
The BCM4349B1 supports 16 bits transparent data on its I2S port.
If BT_VOICE_TRANSPARENT is used when accepting a SCO connection, this
gives only garbage audio while using BT_VOICE_TRANSPARENT_16BIT gives
correct audio.
This has been tested with connection to iPhone 14 and Samsung S24.

netfilter: nf_tables: do not defer rule destruction via call_rcu
nf_tables_chain_destroy can sleep, it can't be used from call_rcu
callbacks.
Moreover, nf_tables_rule_release() is only safe for error unwinding,
while transaction mutex is held and the to-be-desroyed rule was not
exposed to either dataplane or dumps, as it deactives+frees without
the required synchronize_rcu() in-between.
nft_rule_expr_deactivate() callbacks will change ->use counters
of other chains/sets, see e.g. nft_lookup .deactivate callback, these
must be serialized via transaction mutex.
Also add a few lockdep asserts to make this more explicit.
Calling synchronize_rcu() isn't ideal, but fixing this without is hard
and way more intrusive. As-is, we can get:
WARNING: .. net/netfilter/nf_tables_api.c:5515 nft_set_destroy+0x..
Workqueue: events nf_tables_trans_destroy_work
RIP: 0010:nft_set_destroy+0x3fe/0x5c0
Call Trace:
<TASK>
nf_tables_trans_destroy_work+0x6b7/0xad0
process_one_work+0x64a/0xce0
worker_thread+0x613/0x10d0
In case the synchronize_rcu becomes an issue, we can explore alternatives.
One way would be to allocate nft_trans_rule objects + one nft_trans_chain
object, deactivate the rules + the chain and then defer the freeing to the
nft destroy workqueue. We'd still need to keep the synchronize_rcu path as
a fallback to handle -ENOMEM corner cases though.

Bluetooth: Improve setsockopt() handling of malformed user input
The bt_copy_from_sockptr() return value is being misinterpreted by most users: a non-zero result is mistakenly assumed to represent an error code, but actually indicates the number of bytes that could not be copied. Remove bt_copy_from_sockptr() and adapt callers to use copy_safe_from_sockptr(). For sco_sock_setsockopt() (case BT_CODEC) use copy_struct_from_sockptr() to scrub parts of uninitialized buffer. Opportunistically, rename `len` to `optlen` in hci_sock_setsockopt_old() and hci_sock_setsockopt(). Fixes: |

net: defer final 'struct net' free in netns dismantle
Ilya reported a slab-use-after-free in dst_destroy [1]
Issue is in xfrm6_net_init() and xfrm4_net_init() :
They copy xfrm[46]_dst_ops_template into net->xfrm.xfrm[46]_dst_ops.
But net structure might be freed before all the dst callbacks are
called. So when dst_destroy() calls later :
if (dst->ops->destroy)
dst->ops->destroy(dst);
dst->ops points to the old net->xfrm.xfrm[46]_dst_ops, which has been freed.
See a relevant issue fixed in :

The root cause is a network namespace creation failing after successful
initialization of the ipmr subsystem. Such a case is not currently
matched by the ipmr_can_free_table() helper.
New namespaces are zeroed on allocation and inserted into net ns list
only after successful creation; when deleting an ipmr table, the list
next pointer can be NULL only on netns initialization failure.
Update the ipmr_can_free_table() checks leveraging such condition.

netfilter: nft_inner: incorrect percpu area handling under softirq
Softirq can interrupt ongoing packet from process context that is
walking over the percpu area that contains inner header offsets.
Disable bh and perform three checks before restoring the percpu inner
header offsets to validate that the percpu area is valid for this
skbuff:
1) If the NFT_PKTINFO_INNER_FULL flag is set on, then this skbuff
has already been parsed before for inner header fetching to
register.
2) Validate that the percpu area refers to this skbuff using the
skbuff pointer as a cookie. If there is a cookie mismatch, then
this skbuff needs to be parsed again.
3) Finally, validate if the percpu area refers to this tunnel type.
Only after these three checks the percpu area is restored to a on-stack
copy and bh is enabled again.
After inner header fetching, the on-stack copy is stored back to the
percpu area.

wifi: mac80211: fix vif addr when switching from monitor to station
Since adding support for opting out of virtual monitor support, a zero vif
addr was used to indicate passive vs active monitor to the driver.
This would break the vif->addr when changing the netdev mac address before
switching the interface from monitor to sta mode.
Fix the regression by adding a separate flag to indicate whether vif->addr
is valid.

wifi: mac80211: fix a queue stall in certain cases of CSA
If we got an unprotected action frame with CSA and then we heard the
beacon with the CSA IE, we'll block the queues with the CSA reason
twice. Since this reason is refcounted, we won't wake up the queues
since we wake them up only once and the ref count will never reach 0.
This led to blocked queues that prevented any activity (even
disconnection wouldn't reset the queue state and the only way to recover
would be to reload the kernel module.
Fix this by not refcounting the CSA reason.
It becomes now pointless to maintain the csa_blocked_queues state.
Remove it.

tcp: populate XPS related fields of timewait sockets
syzbot reported that netdev_core_pick_tx() was reading an uninitialized field [1]. This is indeed hapening for timewait sockets after recent commits. We can copy the original established socket sk_tx_queue_mapping and sk_rx_queue_mapping fields, instead of adding more checks in fast paths. As a bonus, packets will use the same transmit queue than prior ones, this potentially can avoid reordering.

Networking changes for 6.13.
The most significant set of changes is the per netns RTNL. The new
behavior is disabled by default, regression risk should be contained.
Notably the new config knob PTP_1588_CLOCK_VMCLOCK will inherit its
default value from PTP_1588_CLOCK_KVM, as the first is intended to be
a more reliable replacement for the latter.
Core
----
- Started a very large, in-progress, effort to make the RTNL lock
scope per network-namespace, thus reducing the lock contention
significantly in the containerized use-case, comprising:
- RCU-ified some relevant slices of the FIB control path
- introduce basic per netns locking helpers
- namespacified the IPv4 address hash table
- remove rtnl_register{,_module}() in favour of rtnl_register_many()
- refactor rtnl_{new,del,set}link() moving as much validation as
possible out of RTNL lock
- convert all phonet doit() and dumpit() handlers to RCU
- convert IPv4 addresses manipulation to per-netns RTNL
- convert virtual interface creation to per-netns RTNL
the per-netns lock infra is guarded by the CONFIG_DEBUG_NET_SMALL_RTNL
knob, disabled by default ad interim.
- Introduce NAPI suspension, to efficiently switching between busy
polling (NAPI processing suspended) and normal processing.
- Migrate the IPv4 routing input, output and control path from direct
ToS usage to DSCP macros. This is a work in progress to make ECN
handling consistent and reliable.
- Add drop reasons support to the IPv4 rotue input path, allowing
better introspection in case of packets drop.
- Make FIB seqnum lockless, dropping RTNL protection for read
access.
- Make inet{,v6} addresses hashing less predicable.
- Allow providing timestamp OPT_ID via cmsg, to correlate TX packets
and timestamps
Things we sprinkled into general kernel code
--------------------------------------------
- Add small file operations for debugfs, to reduce the struct ops size.
- Refactoring and optimization for the implementation of page_frag API,
This is a preparatory work to consolidate the page_frag
implementation.
Netfilter
---------
- Optimize set element transactions to reduce memory consumption
- Extended netlink error reporting for attribute parser failure.
- Make legacy xtables configs user selectable, giving users
the option to configure iptables without enabling any other config.
- Address a lot of false-positive RCU issues, pointed by recent
CI improvements.
BPF
---
- Put xsk sockets on a struct diet and add various cleanups. Overall,
this helps to bump performance by 12% for some workloads.
- Extend BPF selftests to increase coverage of XDP features in
combination with BPF cpumap.
- Optimize and homogenize bpf_csum_diff helper for all archs and also
add a batch of new BPF selftests for it.
- Extend netkit with an option to delegate skb->{mark,priority}
scrubbing to its BPF program.
- Make the bpf_get_netns_cookie() helper available also to tc(x) BPF
programs.
Protocols
---------
- Introduces 4-tuple hash for connected udp sockets, speeding-up
significantly connected sockets lookup.
- Add a fastpath for some TCP timers that usually expires after close,
the socket lock contention.
- Add inbound and outbound xfrm state caches to speed up state lookups.
- Avoid sending MPTCP advertisements on stale subflows, reducing
risks on loosing them.
- Make neighbours table flushing more scalable, maintaining per device
neigh lists.
Driver API
----------
- Introduce a unified interface to configure transmission H/W shaping,
and expose it to user-space via generic-netlink.
- Add support for per-NAPI config via netlink. This makes napi
configuration persistent across queues removal and re-creation.
Requires driver updates, currently supported drivers are:
nVidia/Mellanox mlx4 and mlx5, Broadcom brcm and Intel ice.
- Add ethtool support for writing SFP / PHY firmware blocks.
- Track RSS context allocation from ethtool core.
- Implement support for mirroring to DSA CPU port, via TC mirror
offload.
- Consolidate FDB updates notification, to avoid duplicates on
device-specific entries.
- Expose DPLL clock quality level to the user-space.
- Support master-slave PHY config via device tree.
Tests and tooling
-----------------
- forwarding: introduce deferred commands, to simplify
the cleanup phase
Drivers
-------
- Updated several drivers - Amazon vNic, Google vNic, Microsoft vNic,
Intel e1000e and Broadcom Tigon3 - to use netdev-genl to link the
IRQs and queues to NAPI IDs, allowing busy polling and better
introspection.

ipv6/udp: Add 4-tuple hash for connected socket
Implement ipv6 udp hash4 like that in ipv4. The major difference is that the hash value should be calculated with udp6_ehashfn(). Besides, ipv4-mapped ipv6 address is handled before hash() and rehash(). Export udp_ehashfn because now we use it in udpv6 rehash. Core procedures of hash/unhash/rehash are same as ipv4, and udpv4 and udpv6 share the same udptable, so some functions in ipv4 hash4 can also be shared.

ipv4/udp: Add 4-tuple hash for connected socket
Currently, the udp_table has two hash table, the port hash and portaddr
hash. Usually for UDP servers, all sockets have the same local port and
addr, so they are all on the same hash slot within a reuseport group.
In some applications, UDP servers use connect() to manage clients. In
particular, when firstly receiving from an unseen 4 tuple, a new socket
is created and connect()ed to the remote addr:port, and then the fd is
used exclusively by the client.
Once there are connected sks in a reuseport group, udp has to score all
sks in the same hash2 slot to find the best match. This could be
inefficient with a large number of connections, resulting in high
softirq overhead.
To solve the problem, this patch implement 4-tuple hash for connected
udp sockets. During connect(), hash4 slot is updated, as well as a
corresponding counter, hash4_cnt, in hslot2. In __udp4_lib_lookup(),
hslot4 will be searched firstly if the counter is non-zero. Otherwise,
hslot2 is used like before. Note that only connected sockets enter this
hash4 path, while un-connected ones are not affected.
hlist_nulls is used for hash4, because we probably move to another hslot
wrongly when lookup with concurrent rehash. Then we check nulls at the
list end to see if we should restart lookup. Because udp does not use
SLAB_TYPESAFE_BY_RCU, we don't need to touch sk_refcnt when lookup.
Stress test results (with 1 cpu fully used) are shown below, in pps:
(1) _un-connected_ socket as server
[a] w/o hash4: 1,825176
[b] w/ hash4: 1,831750 (+0.36%)
(2) 500 _connected_ sockets as server
[c] w/o hash4: 290860 (only 16% of [a])
[d] w/ hash4: 1,889658 (+3.1% compared with [b])
With hash4, compute_score is skipped when lookup, so [d] is slightly
better than [b].

net/udp: Add 4-tuple hash list basis
Add a new hash list, hash4, in udp table. It will be used to implement 4-tuple hash for connected udp sockets. This patch adds the hlist to table, and implements helpers and the initialization. 4-tuple hash is implemented in the following patch. hash4 uses hlist_nulls to avoid moving wrongly onto another hlist due to concurrent rehash, because rehash() can happen with lookup().

net/udp: Add a new struct for hash2 slot
Preparing for udp 4-tuple hash (uhash4 for short). To implement uhash4 without cache line missing when lookup, hslot2 is used to record the number of hashed sockets in hslot4. Thus adding a new struct udp_hslot_main with field hash4_cnt, which is used by hash2. The new struct is used to avoid doubling the size of udp_hslot. Before uhash4 lookup, firstly checking hash4_cnt to see if there are hashed sks in hslot4. Because hslot2 is always used in lookup, there is no cache line miss. Related helpers are updated, and use the helpers as possible. uhash4 is implemented in following patches.

The HCI command is specified by the Opcode, any arbitrary is supported including vendor commands, but contrary to the like of Raw/User channel it is run as an HCI command send by the kernel since it uses its command synchronization thus it is possible to wait for a specific event as a response. Setting event to 0x00 will cause the command to wait for either HCI Command Status or HCI Command Complete. Timeout is specified in seconds, setting it to 0 will cause the default timeout to be used.

netfilter: nf_tables: allocate element update information dynamically
Move the timeout/expire/flag members from nft_trans_one_elem struct into a dybamically allocated structure, only needed when timeout update was requested. This halves size of nft_trans_one_elem struct and allows to compact up to 124 elements in one transaction container rather than 62. This halves memory requirements for a large flush or insert transaction, where ->update remains NULL. Care has to be taken to release the extra data in all spots, including abort path.

netfilter: nf_tables: prepare for multiple elements in nft_trans_elem structure
Add helpers to release the individual elements contained in the trans_elem container structure. No functional change intended. Followup patch will add 'nelems' member and will turn 'priv' into a flexible array. These helpers can then loop over all elements. Care needs to be taken to handle a mix of new elements and existing elements that are being updated (e.g. timeout refresh). Before this patch, NEWSETELEM transaction with update is released early so nft_trans_set_elem_destroy() won't get called, so we need to skip elements marked as update.

net: ip: make ip_route_input_noref() return drop reasons
In this commit, we make ip_route_input_noref() return drop reasons, which come from ip_route_input_rcu(). We need adjust the callers of ip_route_input_noref() to make sure the return value of ip_route_input_noref() is used properly. The errno that ip_route_input_noref() returns comes from ip_route_input and bpf_lwt_input_reroute in the origin logic, and we make them return -EINVAL on error instead. In the following patch, we will make ip_route_input() returns drop reasons too. Signed-off-by: Menglong Dong <dongml2@chinatelecom.cn> Signed-off-by: Paolo Abeni <pabeni@redhat.com> |

net: ip: make fib_validate_source() support drop reasons
In this commit, we make fib_validate_source() and __fib_validate_source() return -reason instead of errno on error. The return value of fib_validate_source can be -errno, 0, and 1. It's hard to make fib_validate_source() return drop reasons directly. The fib_validate_source() will return 1 if the scope of the source(revert) route is HOST. And the __mkroute_input() will mark the skb with IPSKB_DOREDIRECT in this case (combine with some other conditions). And then, a REDIRECT ICMP will be sent in ip_forward() if this flag exists. We can't pass this information to __mkroute_input if we make fib_validate_source() return drop reasons. Therefore, we introduce the wrapper fib_validate_source_reason() for fib_validate_source(), which will return the drop reasons on error. In the origin logic, LINUX_MIB_IPRPFILTER will be counted if fib_validate_source() return -EXDEV. And now, we need to adjust it by checking "reason == SKB_DROP_REASON_IP_RPFILTER". However, this will take effect only after the patch "net: ip: make ip_route_input_noref() return drop reasons", as we can't pass the drop reasons from fib_validate_source() to ip_rcv_finish_core() in this patch.

net: Add control functions for irq suspension
