      =====================================================
      
      We can follow the call chain and find that 'bcm_tx_setup' function
      calls 'memcpy_from_msg' to copy some content to the newly allocated
      frame of 'op->frames'. After that the 'len' field of copied structure
      being compared with some constant value (64 or 8). However, if
      'memcpy_from_msg' returns an error, we will compare some uninitialized
      memory. This triggers 'uninit-value' issue.
      
      This patch will add 'memcpy_from_msg' possible errors processing to
      avoid uninit-value issue.

      can: j1939: prevent deadlock by moving j1939_sk_errqueue() · d1366b28
      Oleksij Rempel authored
      This commit addresses a deadlock situation that can occur in certain
      scenarios, such as when running data TP/ETP transfer and subscribing to
      the error queue while receiving a net down event. The deadlock involves
      locks in the following order:
      
      3
        j1939_session_list_lock ->  active_session_list_lock
        j1939_session_activate
        ...
        j1939_sk_queue_activate_next -> sk_session_queue_lock
        ...
        j1939_xtp_rx_eoma_one
      
      2
        j1939_sk_queue_drop_all  ->  sk_session_queue_lock
        ...
        j1939_sk_netdev_event_netdown -> j1939_socks_lock
        j1939_netdev_notify
      
      1
        j1939_sk_errqueue -> j1939_socks_lock
        __j1939_session_cancel -> active_session_list_lock
        j1939_tp_rxtimer
      
             CPU0                    CPU1
             ----                    ----
        lock(&priv->active_session_list_lock);
                                     lock(&jsk->sk_session_queue_lock);
                                     lock(&priv->active_session_list_lock);
        lock(&priv->j1939_socks_lock);
      
      The solution implemented in this commit is to move the
      j1939_sk_errqueue() call out of the active_session_list_lock context,
      thus preventing the deadlock situation.

      net: phy: micrel: correct KSZ9131RNX EEE capabilities and advertisement · f2e9d083
      Oleksij Rempel authored
      The KSZ9131RNX incorrectly shows EEE capabilities in its registers.
      Although the "EEE control and capability 1" (Register 3.20) is set to 0,
      indicating no EEE support, the "EEE advertisement 1" (Register 7.60) is
      set to 0x6, advertising EEE support for 1000BaseT/Full and
      100BaseT/Full.
      This inconsistency causes PHYlib to assume there is no EEE support,
      preventing control over EEE advertisement, which is enabled by default.
      
      This patch resolves the issue by utilizing the ksz9477_get_features()
      function to correctly set the EEE capabilities for the KSZ9131RNX. This
      adjustment allows proper control over EEE advertisement and ensures
      accurate representation of the device's capabilities.

      vsock/loopback: use only sk_buff_head.lock to protect the packet queue · b465518d
      Stefano Garzarella authored
      pkt_list_lock was used before commit 71dc9ec9 ("virtio/vsock:
      replace virtio_vsock_pkt with sk_buff") to protect the packet queue.
      After that commit we switched to sk_buff and we are using
      sk_buff_head.lock in almost every place to protect the packet queue
      except in vsock_loopback_work() when we call skb_queue_splice_init().
      
      As reported by syzbot, this caused unlocked concurrent access to the
      packet queue between vsock_loopback_work() and
      vsock_loopback_cancel_pkt() since it is not holding pkt_list_lock.
      
      With the introduction of sk_buff_head, pkt_list_lock is redundant and
      can cause confusion, so let's remove it and use sk_buff_head.lock
      everywhere to protect the packet queue access.

      net/net_failover: fix txq exceeding warning · e3cbdcb0
      Faicker Mo authored
      The failover txq is inited as 16 queues.
      when a packet is transmitted from the failover device firstly,
      the failover device will select the queue which is returned from
      the primary device if the primary device is UP and running.
      If the primary device txq is bigger than the default 16,
      it can lead to the following warning:
      eth0 selects TX queue 18, but real number of TX queues is 16
      
      The warning backtrace is:

      net: phy: dp83869: fix default value for tx-/rx-internal-delay · 82e2c39f
      Josua Mayer authored
      dp83869 internally uses a look-up table for mapping supported delays in
      nanoseconds to register values.
      When specific delays are defined in device-tree, phy_get_internal_delay
      does the lookup automatically returning an index.
      
      The default case wrongly assigns the nanoseconds value from the lookup
      table, resulting in numeric value 2000 applied to delay configuration
      register, rather than the expected index values 0-7 (7 for 2000).
      Ultimately this issue broke RX for 1Gbps links.
      
      Fix default delay configuration by assigning the intended index value
      directly.

      sfc: ef10: don't overwrite offload features at NIC reset · ca4a80e4
      Íñigo Huguet authored
      At NIC reset, some offload features related to encapsulated traffic
      might have changed (this mainly happens if the firmware-variant is
      changed with the sfboot userspace tool). Because of this, features are
      checked and set again at reset time.
      
      However, this was not done right, and some features were improperly
      overwritten at NIC reset:
      - Tunneled IPv6 segmentation was always disabled
      - Features disabled with ethtool were reenabled
      - Features that becomes unsupported after the reset were not disabled
      
      Also, checking if the device supports IPV6_CSUM to enable TSO6 is no
      longer necessary because all currently supported devices support it.
      Additionally, move the assignment of some other features to the
      EF10_OFFLOAD_FEATURES macro, like it is done in ef100, leaving the
      selection of features in efx_pci_probe_post_io a bit cleaner.

      The main changes are:
      
      1) Fix verification issues in some BPF programs due to their stack usage
         patterns, from Eduard Zingerman.
      
      2) Fix to add missing overflow checks in xdp_umem_reg and return an error
         in such case, from Kal Conley.
      
      3) Fix and undo poisoning of strlcpy in libbpf given it broke builds for
         libcs which provided the former like uClibc-ng, from Jesus Sanchez-Palencia.
      
      4) Fix insufficient bpf_jit_limit default to avoid users running into hard
         to debug seccomp BPF errors, from Daniel Borkmann.
      
      5) Fix driver return code when they don't support a bpf_xdp_metadata kfunc
         to make it unambiguous from other errors, from Jesper Dangaard Brouer.
      
      6) Two BPF selftest fixes to address compilation errors from recent changes
         in kernel structures, from Alexei Starovoitov.

      Bluetooth: HCI: Fix global-out-of-bounds · bce56405
      Sungwoo Kim authored
      To loop a variable-length array, hci_init_stage_sync(stage) considers
      that stage[i] is valid as long as stage[i-1].func is valid.
      Thus, the last element of stage[].func should be intentionally invalid
      as hci_init0[], le_init2[], and others did.
      However, amp_init1[] and amp_init2[] have no invalid element, letting
      hci_init_stage_sync() keep accessing amp_init1[] over its valid range.
      This patch fixes this by adding {} in the last of amp_init1[] and
      amp_init2[].

      Howard Chung authored
      The MGMT command: MGMT_OP_ADD_ADV_PATTERNS_MONITOR_RSSI uses variable
      length argument. This causes host not able to register advmon with rssi.
      
      This patch has been locally tested by adding monitor with rssi via
      btmgmt on a kernel 6.1 machine.

      Bluetooth: btsdio: fix use after free bug in btsdio_remove due to unfinished work · 1e9ac114
      Zheng Wang authored
      In btsdio_probe, &data->work was bound with btsdio_work.In
      btsdio_send_frame, it was started by schedule_work.
      
      If we call btsdio_remove with an unfinished job, there may
      be a race condition and cause UAF bug on hdev.

      Bluetooth: btqcomsmd: Fix command timeout after setting BD address · 5d44ab9e
      Stephan Gerhold authored
      On most devices using the btqcomsmd driver (e.g. the DragonBoard 410c
      and other devices based on the Qualcomm MSM8916/MSM8909/... SoCs)
      the Bluetooth firmware seems to become unresponsive for a while after
      setting the BD address. On recent kernel versions (at least 5.17+)
      this often causes timeouts for subsequent commands, e.g. the HCI reset
      sent by the Bluetooth core during initialization:
      
          Bluetooth: hci0: Opcode 0x c03 failed: -110
      
      Unfortunately this behavior does not seem to be documented anywhere.
      Experimentation suggests that the minimum necessary delay to avoid
      the problem is ~150us. However, to be sure add a sleep for > 1ms
      in case it is a bit longer on other firmware versions.
      
      Older kernel versions are likely also affected, although perhaps with
      slightly different errors or less probability. Side effects can easily
      hide the issue in most cases, e.g. unrelated incoming interrupts that
      cause the necessary delay.

      Reinstate "GFS2: free disk inode which is deleted by remote node -V2" · 260595b4
      Bob Peterson authored
      It turns out that reverting commit 970343cd ("GFS2: free disk inode
      which is deleted by remote node -V2") causes a regression related to
      evicting inodes that were unlinked on a different cluster node.
      
      We could also have simply added a call to d_mark_dontcache() to function
      gfs2_try_evict(), but the original pre-revert code is better tested and
      proven.
      
      This reverts commit 445cb127.
