       "Including fixes from can, bpf and netfilter.
      
        There are a bunch of regressions addressed here, but hopefully nothing
        spectacular. We are still waiting the driver fix from Intel, mentioned
        by Jakub in the previous networking pull.
      
        Current release - regressions:
      
         - core: add softirq safety to netdev_rename_lock
      
         - tcp: fix tcp_rcv_fastopen_synack() to enter TCP_CA_Loss for failed
           TFO
      
         - batman-adv: fix RCU race at module unload time
      
        Previous releases - regressions:
      
         - openvswitch: get related ct labels from its master if it is not
           confirmed
      
         - eth: bonding: fix incorrect software timestamping report
      
         - eth: mlxsw: fix memory corruptions on spectrum-4 systems
      
         - eth: ionic: use dev_consume_skb_any outside of napi
      
        Previous releases - always broken:
      
         - netfilter: fully validate NFT_DATA_VALUE on store to data registers
      
         - unix: several fixes for OoB data
      
         - tcp: fix race for duplicate reqsk on identical SYN
      
         - bpf:
             - fix may_goto with negative offset
             - fix the corner case with may_goto and jump to the 1st insn
             - fix overrunning reservations in ringbuf
      
         - can:
             - j1939: recover socket queue on CAN bus error during BAM
               transmission
             - mcp251xfd: fix infinite loop when xmit fails

      Netfilter fixes for net
      
      The following patchset contains two Netfilter fixes for net:
      
      Patch #1 fixes CONFIG_SYSCTL=n for a patch coming in the previous PR
      	 to move the sysctl toggle to enable SRv6 netfilter hooks from
      	 nf_conntrack to the core, from Jianguo Wu.
      
      Patch #2 fixes a possible pointer leak to userspace due to insufficient
      	 validation of NFT_DATA_VALUE.
      
      Linus found this pointer leak to userspace via zdi-disclosures@ and
      forwarded the notice to Netfilter maintainers, he appears as reporter
      because whoever found this issue never approached Netfilter
      maintainers neither via security@ nor in private.

      selftest: af_unix: Add SO_OOBINLINE test cases in msg_oob.c · 436352e8
      Kuniyuki Iwashima authored
      When SO_OOBINLINE is enabled on a socket, MSG_OOB can be recv()ed
      without MSG_OOB flag, and ioctl(SIOCATMARK) will behaves differently.
      
      This patch adds some test cases for SO_OOBINLINE.
      
      Note the new test cases found two bugs in TCP.
      
        1) After reading OOB data with non-inline mode, we can re-read
           the data by setting SO_OOBINLINE.
      
        #  RUN           msg_oob.no_peek.inline_oob_ahead_break ...

        ok 14 msg_oob.no_peek.inline_oob_ahead_break
      
        2) The head OOB data is dropped if SO_OOBINLINE is disabled
           if a new OOB data is queued.
      
        #  RUN           msg_oob.no_peek.inline_ex_oob_drop ...

      af_unix: Don't stop recv() at consumed ex-OOB skb. · 36893ef0
      Kuniyuki Iwashima authored
      Currently, recv() is stopped at a consumed OOB skb even if a new
      OOB skb is queued and we can ignore the old OOB skb.
      
        >>> from socket import *
        >>> c1, c2 = socket(AF_UNIX, SOCK_STREAM)
        >>> c1.send(b'hellowor', MSG_OOB)
        8
        >>> c2.recv(1, MSG_OOB)  # consume OOB data stays at middle of recvq.
        b'r'
        >>> c1.send(b'ld', MSG_OOB)
        2
        >>> c2.recv(10)          # recv() stops at the old consumed OOB
        b'hellowo'               # should be 'hellowol'
      
      manage_oob() should not stop recv() at the old consumed OOB skb if
      there is a new OOB data queued.
      
      Note that TCP behaviour is apparently wrong in this test case because
      we can recv() the same OOB data twice.

      selftest: af_unix: Add non-TCP-compliant test cases in msg_oob.c. · f5ea0768
      Kuniyuki Iwashima authored
      While testing, I found some weird behaviour on the TCP side as well.
      
      For example, TCP drops the preceding OOB data when queueing a new
      OOB data if the old OOB data is at the head of recvq.
      
        #  RUN           msg_oob.no_peek.ex_oob_drop ...
        # msg_oob.c:146:ex_oob_drop:AF_UNIX :x

        # msg_oob.c:146:ex_oob_drop:AF_UNIX :y
        # msg_oob.c:147:ex_oob_drop:TCP     :Invalid argument
        #            OK  msg_oob.no_peek.ex_oob_drop
        ok 9 msg_oob.no_peek.ex_oob_drop
      
        #  RUN           msg_oob.no_peek.ex_oob_drop_2 ...
        # msg_oob.c:146:ex_oob_drop_2:AF_UNIX :x
        # msg_oob.c:147:ex_oob_drop_2:TCP     :Resource temporarily unavailable
        #            OK  msg_oob.no_peek.ex_oob_drop_2
        ok 10 msg_oob.no_peek.ex_oob_drop_2
      
      This patch allows AF_UNIX's MSG_OOB implementation to produce different
      results from TCP when operations are guarded with tcp_incompliant{}.

      af_unix: Don't stop recv(MSG_DONTWAIT) if consumed OOB skb is at the head. · 93c99f21
      Kuniyuki Iwashima authored
      Let's say a socket send()s "hello" with MSG_OOB and "world" without flags,
      
        >>> from socket import *
        >>> c1, c2 = socketpair(AF_UNIX)
        >>> c1.send(b'hello', MSG_OOB)
        5
        >>> c1.send(b'world')
        5
      
      and its peer recv()s "hell" and "o".
      
        >>> c2.recv(10)
        b'hell'
        >>> c2.recv(1, MSG_OOB)
        b'o'
      
      Now the consumed OOB skb stays at the head of recvq to return a correct
      value for ioctl(SIOCATMARK), which is broken now and fixed by a later
      patch.
      
      Then, if peer issues recv() with MSG_DONTWAIT, manage_oob() returns NULL,
      so recv() ends up with -EAGAIN.

      When the consumed OOB skb is at the head of the queue, we need to fetch
      the next skb to fix the weird behaviour.
      
      Note that the issue does not happen without MSG_DONTWAIT because we can
      retry after manage_oob().
      
      This patch also adds a test case that covers the issue.

      af_unix: Stop recv(MSG_PEEK) at consumed OOB skb. · b94038d8
      Kuniyuki Iwashima authored
      After consuming OOB data, recv() reading the preceding data must break at
      the OOB skb regardless of MSG_PEEK.
      
      Currently, MSG_PEEK does not stop recv() for AF_UNIX, and the behaviour is
      not compliant with TCP.
      
        >>> from socket import *
        >>> c1, c2 = socketpair(AF_UNIX)
        >>> c1.send(b'hello', MSG_OOB)
        5
        >>> c1.send(b'world')
        5
        >>> c2.recv(1, MSG_OOB)
        b'o'
        >>> c2.recv(9, MSG_PEEK)  # This should return b'hell'
        b'hellworld'              # even with enough buffer.
      
      Let's fix it by returning NULL for consumed skb and unlinking it only if
      MSG_PEEK is not specified.
      
      This patch also adds test cases that add recv(MSG_PEEK) before each recv().

      selftest: af_unix: Add msg_oob.c. · d098d772
      Kuniyuki Iwashima authored
      AF_UNIX's MSG_OOB functionality lacked thorough testing, and we found
      some bizarre behaviour.
      
      The new selftest validates every MSG_OOB operation against TCP as a
      reference implementation.
      
      This patch adds only a few tests with basic send() and recv() that
      do not fail.
      
      The following patches will add more test cases for SO_OOBINLINE, SIGURG,
      EPOLLPRI, and SIOCATMARK.

      selftest: af_unix: Remove test_unix_oob.c. · 7d139181
      Kuniyuki Iwashima authored
      test_unix_oob.c does not fully cover AF_UNIX's MSG_OOB functionality,
      thus there are discrepancies between TCP behaviour.
      
      Also, the test uses fork() to create message producer, and it's not
      easy to understand and add more test cases.
      
      Let's remove test_unix_oob.c and rewrite a new test.

      tracing/net_sched: NULL pointer dereference in perf_trace_qdisc_reset() · bab49231
      Yunseong Kim authored
      In the TRACE_EVENT(qdisc_reset) NULL dereference occurred from
      
       qdisc->dev_queue->dev <NULL> ->name
      
      This situation simulated from bunch of veths and Bluetooth disconnection
      and reconnection.
      
      During qdisc initialization, qdisc was being set to noop_queue.
      In veth_init_queue, the initial tx_num was reduced back to one,
      causing the qdisc reset to be called with noop, which led to the kernel
      panic.
      
      I've attached the GitHub gist link that C converted syz-execprogram
      source code and 3 log of reproduced vmcore-dmesg.
      
       https://gist.github.com/yskelg/cc64562873ce249cdd0d5a358b77d740
      
      Yeoreum and I use two fuzzing tool simultaneously.
      
      One process with syz-executor : https://github.com/google/syzkaller
      
       $ ./syz-execprog -executor=./syz-executor -repeat=1 -sandbox=setuid \
          -enable=none -collide=false log1
      
      The other process with perf fuzzer:
       https://github.com/deater/perf_event_tests/tree/master/fuzzer
      
       $ perf_event_tests/fuzzer/perf_fuzzer
      
      I think this will happen on the kernel version.
      
       Linux kernel version +v6.7.10, +v6.8, +v6.9 and it could happen in v6.10.
      
      This occurred from 51270d57. I think this patch is absolutely
      necessary. Previously, It was showing not intended string value of name.
      
      I've reproduced 3 time from my fedora 40 Debug Kernel with any other module
      or patched.

      After applying our patch, I didn't find any kernel panic errors.
      
      We've found a simple reproducer
      
       # echo 1 > /sys/kernel/debug/tracing/events/qdisc/qdisc_reset/enable
      
       # ip link add veth0 type veth peer name veth1
      
       Error: Unknown device type.
      
      However, without our patch applied, I tested upstream 6.10.0-rc3 kernel
      using the qdisc_reset event and the ip command on my qemu virtual machine.
      
      This 2 commands makes always kernel panic.

      netfilter: nf_tables: fully validate NFT_DATA_VALUE on store to data registers · 7931d329
      Pablo Neira Ayuso authored
      register store validation for NFT_DATA_VALUE is conditional, however,
      the datatype is always either NFT_DATA_VALUE or NFT_DATA_VERDICT. This
      only requires a new helper function to infer the register type from the
      set datatype so this conditional check can be removed. Otherwise,
      pointer to chain object can be leaked through the registers.

      Takashi Iwai authored
      The recent fix for Lenovo IdeaPad 330-17IKB replaced the quirk entry,
      and this eventually breaks the existing quirk for Lenovo Yoga Duet 7
      13ITL6 equipped with the same PCI SSID 17aa:3820.
      
      For applying a proper quirk for each model, check the codec SSID
      additionally.  Fortunately Yoga Duet has a different codec SSID,
      0x17aa3802.
      
      (Interestingly, 17aa:3802 has another conflict of SSID between another
      Yoga model vs 14IRP8 which we had to work around similarly.)

      tcp: fix tcp_rcv_fastopen_synack() to enter TCP_CA_Loss for failed TFO · 5dfe9d27
      Neal Cardwell authored
      Testing determined that the recent commit 9e046bb1 ("tcp: clear
      tp->retrans_stamp in tcp_rcv_fastopen_synack()") has a race, and does
      not always ensure retrans_stamp is 0 after a TFO payload retransmit.
      
      If transmit completion for the SYN+data skb happens after the client
      TCP stack receives the SYNACK (which sometimes happens), then
      retrans_stamp can erroneously remain non-zero for the lifetime of the
      connection, causing a premature ETIMEDOUT later.
      
      Testing and tracing showed that the buggy scenario is the following
      somewhat tricky sequence:
      
      + Client attempts a TFO handshake. tcp_send_syn_data() sends SYN + TFO
        cookie + data in a single packet in the syn_data skb. It hands the
        syn_data skb to tcp_transmit_skb(), which makes a clone. Crucially,
        it then reuses the same original (non-clone) syn_data skb,
        transforming it by advancing the seq by one byte and removing the
        FIN bit, and enques the resulting payload-only skb in the
        sk->tcp_rtx_queue.
      
      + Client sets retrans_stamp to the start time of the three-way
        handshake.
      
      + Cookie mismatches or server has TFO disabled, and server only ACKs
        SYN.
      
      + tcp_ack() sees SYN is acked, tcp_clean_rtx_queue() clears
        retrans_stamp.
      
      + Since the client SYN was acked but not the payload, the TFO failure
        code path in tcp_rcv_fastopen_synack() tries to retransmit the
        payload skb.  However, in some cases the transmit completion for the
        clone of the syn_data (which had SYN + TFO cookie + data) hasn't
        happened.  In those cases, skb_still_in_host_queue() returns true
        for the retransmitted TFO payload, because the clone of the syn_data
        skb has not had its tx completetion.
      
      + Because skb_still_in_host_queue() finds skb_fclone_busy() is true,
        it sets the TSQ_THROTTLED bit and the retransmit does not happen in
        the tcp_rcv_fastopen_synack() call chain.
      
      + The tcp_rcv_fastopen_synack() code next implicitly assumes the
        retransmit process is finished, and sets retrans_stamp to 0 to clear
        it, but this is later overwritten (see below).
      
      + Later, upon tx completion, tcp_tsq_write() calls
        tcp_xmit_retransmit_queue(), which puts the retransmit in flight and
        sets retrans_stamp to a non-zero value.
      
      + The client receives an ACK for the retransmitted TFO payload data.
      
      + Since we're in CA_Open and there are no dupacks/SACKs/DSACKs/ECN to
        make tcp_ack_is_dubious() true and make us call
        tcp_fastretrans_alert() and reach a code path that clears
        retrans_stamp, retrans_stamp stays nonzero.
      
      + Later, if there is a TLP, RTO, RTO sequence, then the connection
        will suffer an early ETIMEDOUT due to the erroneously ancient
        retrans_stamp.
      
      The fix: this commit refactors the code to have
      tcp_rcv_fastopen_synack() retransmit by reusing the relevant parts of
      tcp_simple_retransmit() that enter CA_Loss (without changing cwnd) and
      call tcp_xmit_retransmit_queue(). We have tcp_simple_retransmit() and
      tcp_rcv_fastopen_synack() share code in this way because in both cases
      we get a packet indicating non-congestion loss (MTU reduction or TFO
      failure) and thus in both cases we want to retransmit as many packets
      as cwnd allows, without reducing cwnd. And given that retransmits will
      set retrans_stamp to a non-zero value (and may do so in a later
      calling context due to TSQ), we also want to enter CA_Loss so that we
      track when all retransmitted packets are ACked and clear retrans_stamp
      when that happens (to ensure later recurring RTOs are using the
      correct retrans_stamp and don't declare ETIMEDOUT prematurely).

      ionic: use dev_consume_skb_any outside of napi · 84b767f9
      Shannon Nelson authored
      If we're not in a NAPI softirq context, we need to be careful
      about how we call napi_consume_skb(), specifically we need to
      call it with budget==0 to signal to it that we're not in a
      safe context.
      
      This was found while running some configuration stress testing
      of traffic and a change queue config loop running, and this
      curious note popped out:

      and
          DEBUG_NET_WARN_ON_ONCE(!in_softirq());
      
      Those are pretty big hints that we're doing it wrong.  We can pass a
      context hint down through the calls to let ionic_tx_clean() know what
      we're doing so it can call napi_consume_skb() correctly.

      net: dsa: microchip: fix wrong register write when masking interrupt · b1c4b4d4
      Tristram Ha authored
      The switch global port interrupt mask, REG_SW_PORT_INT_MASK__4, is
      defined as 0x001C in ksz9477_reg.h.  The designers used 32-bit value in
      anticipation for increase of port count in future product but currently
      the maximum port count is 7 and the effective value is 0x7F in register
      0x001F.  Each port has its own interrupt mask and is defined as 0x#01F.
      It uses only 4 bits for different interrupts.
      
      The developer who implemented the current interrupt mechanism in the
      switch driver noticed there are similarities between the mechanism to
      mask port interrupts in global interrupt and individual interrupts in
      each port and so used the same code to handle these interrupts.  He
      updated the code to use the new macro REG_SW_PORT_INT_MASK__1 which is
      defined as 0x1F in ksz_common.h but he forgot to update the 32-bit write
      to 8-bit as now the mask registers are 0x1F and 0x#01F.
      
      In addition all KSZ switches other than the KSZ9897/KSZ9893 and LAN937X
      families use only 8-bit access and so this common code will eventually
      be changed to accommodate them.

      ALSA: dmaengine_pcm: terminate dmaengine before synchronize · 6a7db25a
      Shengjiu Wang authored
      When dmaengine supports pause function, in suspend state,
      dmaengine_pause() is called instead of dmaengine_terminate_async(),
      
      In end of playback stream, the runtime->state will go to
      SNDRV_PCM_STATE_DRAINING, if system suspend & resume happen
      at this time, application will not resume playback stream, the
      stream will be closed directly, the dmaengine_terminate_async()
      will not be called before the dmaengine_synchronize(), which
      violates the call sequence for dmaengine_synchronize().
      
      This behavior also happens for capture streams, but there is no
      SNDRV_PCM_STATE_DRAINING state for capture. So use
      dmaengine_tx_status() to check the DMA status if the status is
      DMA_PAUSED, then call dmaengine_terminate_async() to terminate
      dmaengine before dmaengine_synchronize().

      Fix race for duplicate reqsk on identical SYN · ff46e3b4
      luoxuanqiang authored
      When bonding is configured in BOND_MODE_BROADCAST mode, if two identical
      SYN packets are received at the same time and processed on different CPUs,
      it can potentially create the same sk (sock) but two different reqsk
      (request_sock) in tcp_conn_request().
      
      These two different reqsk will respond with two SYNACK packets, and since
      the generation of the seq (ISN) incorporates a timestamp, the final two
      SYNACK packets will have different seq values.
      
      The consequence is that when the Client receives and replies with an ACK
      to the earlier SYNACK packet, we will reset(RST) it.
      
      ========================================================================
      
      This behavior is consistently reproducible in my local setup,
      which comprises:
      
                        | NETA1 ------ NETB1 |
      PC_A --- bond --- |                    | --- bond --- PC_B
                        | NETA2 ------ NETB2 |
      
      - PC_A is the Server and has two network cards, NETA1 and NETA2. I have
        bonded these two cards using BOND_MODE_BROADCAST mode and configured
        them to be handled by different CPU.
      
      - PC_B is the Client, also equipped with two network cards, NETB1 and
        NETB2, which are also bonded and configured in BOND_MODE_BROADCAST mode.
      
      If the client attempts a TCP connection to the server, it might encounter
      a failure. Capturing packets from the server side reveals:
      
      10.10.10.10.45182 > localhost: Flags [S], seq 320236027,
      10.10.10.10.45182 > localhost: Flags [S], seq 320236027,
      localhost > 10.10.10.10.45182: Flags [S.], seq 2967855116,
      localhost > 10.10.10.10.45182: Flags [S.], seq 2967855123, <==
      10.10.10.10.45182 > localhost: Flags [.], ack 4294967290,
      10.10.10.10.45182 > localhost: Flags [.], ack 4294967290,
      localhost > 10.10.10.10.45182: Flags [R], seq 2967855117, <==
      localhost > 10.10.10.10.45182: Flags [R], seq 2967855117,
      
      Two SYNACKs with different seq numbers are sent by localhost,
      resulting in an anomaly.
      
      ========================================================================
      
      The attempted solution is as follows:
      Add a return value to inet_csk_reqsk_queue_hash_add() to confirm if the
      ehash insertion is successful (Up to now, the reason for unsuccessful
      insertion is that a reqsk for the same connection has already been
      inserted). If the insertion fails, release the reqsk.
      
      Due to the refcnt, Kuniyuki suggests also adding a return value check
      for the DCCP module; if ehash insertion fails, indicating a successful
      insertion of the same connection, simply release the reqsk as well.
      
      Simultaneously, In the reqsk_queue_hash_req(), the start of the
      req->rsk_timer is adjusted to be after successful insertion.

      ibmvnic: Add tx check to prevent skb leak · 0983d288
      Nick Child authored
      Below is a summary of how the driver stores a reference to an skb during
      transmit:
          tx_buff[free_map[consumer_index]]->skb = new_skb;
          free_map[consumer_index] = IBMVNIC_INVALID_MAP;
          consumer_index ++;
      Where variable data looks like this:
          free_map == [4, IBMVNIC_INVALID_MAP, IBMVNIC_INVALID_MAP, 0, 3]
                                                     	consumer_index^
          tx_buff == [skb=null, skb=<ptr>, skb=<ptr>, skb=null, skb=null]
      
      The driver has checks to ensure that free_map[consumer_index] pointed to
      a valid index but there was no check to ensure that this index pointed
      to an unused/null skb address. So, if, by some chance, our free_map and
      tx_buff lists become out of sync then we were previously risking an
      skb memory leak. This could then cause tcp congestion control to stop
      sending packets, eventually leading to ETIMEDOUT.
      
      Therefore, add a conditional to ensure that the skb address is null. If
      not then warn the user (because this is still a bug that should be
      patched) and free the old pointer to prevent memleak/tcp problems.

      mm/page_alloc: Separate THP PCP into movable and non-movable categories · bf14ed81
      yangge authored
      Since commit 5d0a661d ("mm/page_alloc: use only one PCP list for
      THP-sized allocations") no longer differentiates the migration type of
      pages in THP-sized PCP list, it's possible that non-movable allocation
      requests may get a CMA page from the list, in some cases, it's not
      acceptable.
      
      If a large number of CMA memory are configured in system (for example, the
      CMA memory accounts for 50% of the system memory), starting a virtual
      machine with device passthrough will get stuck.  During starting the
      virtual machine, it will call pin_user_pages_remote(..., FOLL_LONGTERM,
      ...) to pin memory.  Normally if a page is present and in CMA area,
      pin_user_pages_remote() will migrate the page from CMA area to non-CMA
      area because of FOLL_LONGTERM flag.  But if non-movable allocation
      requests return CMA memory, migrate_longterm_unpinnable_pages() will
      migrate a CMA page to another CMA page, which will fail to pass the check
      in check_and_migrate_movable_pages() and cause migration endless.
      
      Call trace:
      pin_user_pages_remote
      --__gup_longterm_locked // endless loops in this function
      ----_get_user_pages_locked
      ----check_and_migrate_movable_pages
      ------migrate_longterm_unpinnable_pages
      --------alloc_migration_target
      
      This problem will also have a negative impact on CMA itself.  For example,
      when CMA is borrowed by THP, and we need to reclaim it through cma_alloc()
      or dma_alloc_coherent(), we must move those pages out to ensure CMA's
      users can retrieve that contigous memory.  Currently, CMA's memory is
      occupied by non-movable pages, meaning we can't relocate them.  As a
      result, cma_alloc() is more likely to fail.
      
      To fix the problem above, we add one PCP list for THP, which will not
      introduce a new cacheline for struct per_cpu_pages.  THP will have 2 PCP
      lists, one PCP list is used by MOVABLE allocation, and the other PCP list
      is used by UNMOVABLE allocation.  MOVABLE allocation contains GPF_MOVABLE,
      and UNMOVABLE allocation contains GFP_UNMOVABLE and GFP_RECLAIMABLE.

      nfs: drop the incorrect assertion in nfs_swap_rw() · 54e7d598
      Christoph Hellwig authored
      Since commit 2282679f ("mm: submit multipage write for SWP_FS_OPS
      swap-space"), we can plug multiple pages then unplug them all together. 
      That means iov_iter_count(iter) could be way bigger than PAGE_SIZE, it
      actually equals the size of iov_iter_npages(iter, INT_MAX).
      
      Note this issue has nothing to do with large folios as we don't support
      THP_SWPOUT to non-block devices.
