In newer hardware, IPA supports more than 32 endpoints. Some registers--such as IPA interrupt registers--represent endpoints as bits in a 4-byte register, and such registers are repeated as needed to represent endpoints beyond the first 32. In ipa_interrupt_suspend_clear_all(), we clear all pending IPA suspend interrupts by reading all status register(s) and writing corresponding registers to clear interrupt conditions. Unfortunately the number of registers to read/write is calculated incorrectly, and as a result we access *many* more registers than intended. This bug occurs only when the IPA hardware signals a SUSPEND interrupt, which happens when a packet is received for an endpoint (or its underlying GSI channel) that is suspended. This situation is difficult to reproduce, but possible. Fix this by correctly computing the number of interrupt registers to read and write. This is the only place in the code where registers that map endpoints or channels this way perform this calculation. Fixes: f298ba78 ("net: ipa: add a parameter to suspend registers") Signed-off-by:

syzbot reported a lockdep violation [1] involving af_unix support of SO_PEEK_OFF. Since SO_PEEK_OFF is inherently not thread safe (it uses a per-socket sk_peek_off field), there is really no point to enforce a pointless thread safety in the kernel. After this patch : - setsockopt(SO_PEEK_OFF) no longer acquires the socket lock. - skb_consume_udp() no longer has to acquire the socket lock. - af_unix no longer needs a special version of sk_set_peek_off(), because it does not lock u->iolock anymore. As a followup, we could replace prot->set_peek_off to be a boolean and avoid an indirect call, since we always use sk_set_peek_off().

AF reserves MCAM entries for each PF, VF present in the system and populates the entry with DMAC and action with default RSS so that basic packet I/O works. Since PF/VF is not aware of the RSS action installed by AF, AF only fixup the actions of the rules installed by PF/VF with corresponding default RSS action. This worked well for rules installed by PF/VF for features like RX VLAN offload and DMAC filters but rules involving action like drop/forward to queue are also getting modified by AF. Hence fix it by setting the default RSS action only if requested by PF/VF. Fixes: 967db352 ("octeontx2-af: add support for multicast/promisc packet replication feature") Signed-off-by:

syzkaller reported an overflown write in arp_req_get(). [0] When ioctl(SIOCGARP) is issued, arp_req_get() looks up an neighbour entry and copies neigh->ha to struct arpreq.arp_ha.sa_data. The arp_ha here is struct sockaddr, not struct sockaddr_storage, so the sa_data buffer is just 14 bytes. In the splat below, 2 bytes are overflown to the next int field, arp_flags. We initialise the field just after the memcpy(), so it's not a problem. However, when dev->addr_len is greater than 22 (e.g. MAX_ADDR_LEN), arp_netmask is overwritten, which could be set as htonl(0xFFFFFFFFUL) in arp_ioctl() before calling arp_req_get(). To avoid the overflow, let's limit the max length of memcpy(). Note that commit b5f0de6d ("net: dev: Convert sa_data to flexible array in struct sockaddr") just silenced syzkaller.

FORTIFY_SOURCE has been ignoring 0-sized destinations while the kernel code base has been converted to flexible arrays. In order to enforce the 0-sized destinations (e.g. with __counted_by), the remaining 0-sized destinations need to be handled. Unfortunately, struct vic_provinfo resists full conversion, as it contains a flexible array of flexible arrays, which is only possible with the 0-sized fake flexible array. Use unsafe_memcpy() to avoid future false positives under CONFIG_FORTIFY_SOURCE. Signed-off-by:

In bond priority testing, we set the primary interface to eth1 and add eth0,1,2 to bond in serial. This is OK in normal times. But when in debug kernel, the bridge port that eth0,1,2 connected would start slowly (enter blocking, forwarding state), which caused the primary interface down for a while after enslaving and active slave changed.

Matthieu Baerts says: ==================== mptcp: misc. fixes for v6.8 This series includes 4 types of fixes: Patches 1 and 2 force the path-managers not to allocate a new address entry when dealing with the "special" ID 0, reserved to the address of the initial subflow. These patches can be backported up to v5.19 and v5.12 respectively. Patch 3 to 6 fix the in-kernel path-manager not to create duplicated subflows. Patch 6 is the main fix, but patches 3 to 5 are some kind of pre-requisities: they fix some data races that could also lead to the creation of unexpected subflows. These patches can be backported up to v5.7, v5.10, v6.0, and v5.15 respectively. Note that patch 3 modifies the existing ULP API. No better solutions have been found for -net, and there is some similar prior art, see commit 0df48c26 ("tcp: add tcpi_bytes_acked to tcp_info"). Please also note that TLS ULP Diag has likely the same issue. Patches 7 to 9 fix issues in the selftests, when executing them on older kernels, e.g. when testing the last version of these kselftests on the v5.15.148 kernel as it is done by LKFT when validating stable kernels. These patches only avoid printing expected errors the console and marking some tests as "OK" while they have been skipped. Patches 7 and 8 can be backported up to v6.6. Patches 10 to 13 make sure all MPTCP selftests subtests have a unique name. It is important to have a unique (sub)test name in TAP, because that's the test identifier. Some CI environments might drop tests with duplicated names. Patches 10 to 12 can be backported up to v6.6. ==================== Signed-off-by:

Simply adding the destination port in the name is then enough to have different names, because the destination port is always different. Note that adding such info takes a bit more space, so we need to increase a bit the width to print the name, simply to keep all the '[ OK ]' aligned as before.

Fullmesh endpoints could end-up unexpectedly generating duplicate subflows - same local and remote addresses - when multiple incoming ADD_ADDR are processed before the PM creates the subflow for the local endpoints. Address the issue explicitly checking for duplicates at subflow creation time. To avoid a quadratic computational complexity, track the unavailable remote address ids in a temporary bitmap and initialize such bitmap with the remote ids of all the existing subflows matching the local address currently processed. The above allows additionally replacing the existing code checking for duplicate entry in the current set with a simple bit test operation.

The local address id is accessed lockless by the NL PM, add all the required ONCE annotation.

The test Davide added in commit ca22da2f ("act_mirred: use the backlog for nested calls to mirred ingress") hangs our testing VMs every 10 or so runs, with the familiar tcp_v4_rcv -> tcp_v4_rcv deadlock reported by lockdep. The problem as previously described by Davide (see Link) is that if we reverse flow of traffic with the redirect (egress -> ingress) we may reach the same socket which generated the packet. And we may still be holding its socket lock. The common solution to such deadlocks is to put the packet in the Rx backlog, rather than run the Rx path inline. Do that for all egress -> ingress reversals, not just once we started to nest mirred calls. In the past there was a concern that the backlog indirection will lead to loss of error reporting / less accurate stats. But the current workaround does not seem to address the issue.

syzkaller reported a warning [0] in inet_csk_destroy_sock() with no repro. WARN_ON(inet_sk(sk)->inet_num && !inet_csk(sk)->icsk_bind_hash); However, the syzkaller's log hinted that connect() failed just before the warning due to FAULT_INJECTION. [1] When connect() is called for an unbound socket, we search for an available ephemeral port. If a bhash bucket exists for the port, we call __inet_check_established() or __inet6_check_established() to check if the bucket is reusable. If reusable, we add the socket into ehash and set inet_sk(sk)->inet_num. Later, we look up the corresponding bhash2 bucket and try to allocate it if it does not exist. Although it rarely occurs in real use, if the allocation fails, we must revert the changes by check_established(). Otherwise, an unconnected socket could illegally occupy an ehash entry. Note that we do not put tw back into ehash because sk might have already responded to a packet for tw and it would be better to free tw earlier under such memory presure.

Tobias Waldekranz says: ==================== net: bridge: switchdev: Ensure MDB events are delivered exactly once When a device is attached to a bridge, drivers will request a replay of objects that were created before the device joined the bridge, that are still of interest to the joining port. Typical examples include FDB entries and MDB memberships on other ports ("foreign interfaces") or on the bridge itself. Conversely when a device is detached, the bridge will synthesize deletion events for all those objects that are still live, but no longer applicable to the device in question. This series eliminates two races related to the synching and unsynching phases of a bridge's MDB with a joining or leaving device, that would cause notifications of such objects to be either delivered twice (1/2), or not at all (2/2). A similar race to the one solved by 1/2 still remains for the FDB. This is much harder to solve, due to the lockless operation of the FDB's rhashtable, and is therefore knowingly left out of this series. v1 -> v2: - Squash the previously separate addition of switchdev_port_obj_act_is_deferred into first consumer. - Use ether_addr_equal to compare MAC addresses. - Document switchdev_port_obj_act_is_deferred (renamed from switchdev_port_obj_is_deferred in v1, to indicate that we also match on the action). - Delay allocations of MDB objects until we know they're needed. - Use non-RCU version of the hash list iterator, now that the MDB is not scanned while holding the RCU read lock. - Add Fixes tag to commit message v2 -> v3: - Fix unlocking in error paths - Access RCU protected port list via mlock_dereference, since MDB is guaranteed to remain constant for the duration of the scan. v3 -> v4: - Limit the search for exiting deferred events in 1/2 to only apply to additions, since the problem does not exist in the deletion case. - Add 2/2, to plug a related race when unoffloading an indirectly associated device. v4 -> v5: - Fix grammatical errors in kerneldoc of switchdev_port_obj_act_is_deferred ==================== Signed-off-by: -

When unoffloading a device, it is important to ensure that all relevant deferred events are delivered to it before it disassociates itself from the bridge. Before this change, this was true for the normal case when a device maps 1:1 to a net_bridge_port, i.e. br0 / swp0 When swp0 leaves br0, the call to switchdev_deferred_process() in del_nbp() makes sure to process any outstanding events while the device is still associated with the bridge. In the case when the association is indirect though, i.e. when the device is attached to the bridge via an intermediate device, like a LAG... br0 / lag0 / swp0 ...then detaching swp0 from lag0 does not cause any net_bridge_port to be deleted, so there was no guarantee that all events had been processed before the device disassociated itself from the bridge. Fix this by always synchronously processing all deferred events before signaling completion of unoffloading back to the driver.

Before this change, generation of the list of MDB events to replay would race against the creation of new group memberships, either from the IGMP/MLD snooping logic or from user configuration. While new memberships are immediately visible to walkers of br->mdb_list, the notification of their existence to switchdev event subscribers is deferred until a later point in time. So if a replay list was generated during a time that overlapped with such a window, it would also contain a replay of the not-yet-delivered event. The driver would thus receive two copies of what the bridge internally considered to be one single event. On destruction of the bridge, only a single membership deletion event was therefore sent. As a consequence of this, drivers which reference count memberships (at least DSA), would be left with orphan groups in their hardware database when the bridge was destroyed. This is only an issue when replaying additions. While deletion events may still be pending on the deferred queue, they will already have been removed from br->mdb_list, so no duplicates can be generated in that scenario. To a user this meant that old group memberships, from a bridge in which a port was previously attached, could be reanimated (in hardware) when the port joined a new bridge, without the new bridge's knowledge. For example, on an mv88e6xxx system, create a snooping bridge and immediately add a port to it: root@infix-06-0b-00:~$ ip link add dev br0 up type bridge mcast_snooping 1 && \ > ip link set dev x3 up master br0 And then destroy the bridge: root@infix-06-0b-00:~$ ip link del dev br0 root@infix-06-0b-00:~$ mvls atu ADDRESS FID STATE Q F 0 1 2 3 4 5 6 7 8 9 a DEV:0 Marvell 88E6393X 33:33:00:00:00:6a 1 static - - 0 . . . . . . . . . . 33:33:ff:87:e4:3f 1 static - - 0 . . . . . . . . . . ff:ff:ff:ff:ff:ff 1 static - - 0 1 2 3 4 5 6 7 8 9 a root@infix-06-0b-00:~$ The two IPv6 groups remain in the hardware database because the port (x3) is notified of the host's membership twice: once via the original event and once via a replay. Since only a single delete notification is sent, the count remains at 1 when the bridge is destroyed. Then add the same port (or another port belonging to the same hardware domain) to a new bridge, this time with snooping disabled: root@infix-06-0b-00:~$ ip link add dev br1 up type bridge mcast_snooping 0 && \ > ip link set dev x3 up master br1 All multicast, including the two IPv6 groups from br0, should now be flooded, according to the policy of br1. But instead the old memberships are still active in the hardware database, causing the switch to only forward traffic to those groups towards the CPU (port 0). Eliminate the race in two steps: 1. Grab the write-side lock of the MDB while generating the replay list. This prevents new memberships from showing up while we are generating the replay list. But it leaves the scenario in which a deferred event was already generated, but not delivered, before we grabbed the lock. Therefore: 2. Make sure that no deferred version of a replay event is already enqueued to the switchdev deferred queue, before adding it to the replay list, when replaying additions.

iucv_path_table is a dynamically allocated array of pointers to struct iucv_path items. Yet, its size is calculated as if it was an array of struct iucv_path items. Signed-off-by:
