syzbot reported a lockdep splat regarding unix_gc_lock and unix_state_lock(). One is called from recvmsg() for a connected socket, and another is called from GC for TCP_LISTEN socket. So, the splat is false-positive. Let's add a dedicated lock class for the latter to suppress the splat. Note that this change is not necessary for net-next.git as the issue is only applied to the old GC impl.

b44_free_rings() accesses b44::rx_buffers (and ::tx_buffers) unconditionally, but b44::rx_buffers is only valid when the device is up (they get allocated in b44_open(), and deallocated again in b44_close()), any other time these are just a NULL pointers. So if you try to change the pause params while the network interface is disabled/administratively down, everything explodes (which likely netifd tries to do).

tls_sk_poll is called without locking the socket, and needs to read strp->msg_ready (via tls_strp_msg_ready). Convert msg_ready to a bool and use READ_ONCE/WRITE_ONCE where needed.

In scenario where pin is registered with multiple parent pins via dpll_pin_on_pin_register(..), all belonging to the same dpll device. A second call to dpll_pin_on_pin_unregister(..) would cause a call trace, as it tries to use already released registration resources (due to fix introduced in b446631f). In this scenario pin was registered twice, so resources are not yet expected to be release until each registered pin/pin pair is unregistered. Currently, the following crash/call trace is produced when ice driver is removed on the system with installed E810T NIC which includes dpll device: WARNING: CPU: 51 PID: 9155 at drivers/dpll/dpll_core.c:809 dpll_pin_ops+0x20/0x30 RIP: 0010:dpll_pin_ops+0x20/0x30 Call Trace: ? __warn+0x7f/0x130 ? dpll_pin_ops+0x20/0x30 dpll_msg_add_pin_freq+0x37/0x1d0 dpll_cmd_pin_get_one+0x1c0/0x400 ? __nlmsg_put+0x63/0x80 dpll_pin_event_send+0x93/0x140 dpll_pin_on_pin_unregister+0x3f/0x100 ice_dpll_deinit_pins+0xa1/0x230 [ice] ice_remove+0xf1/0x210 [ice] Fix by adding a parent pointer as a cookie when creating a registration, also when searching for it.

As interrupts are now requested from ravb_probe(), before calling register_netdev(), ndev->name still contains the template "eth%d", leading to funny names in /proc/interrupts. E.g. on R-Car E3: 89: 0 0 GICv2 93 Level eth%d:ch22:multi 90: 0 3 GICv2 95 Level eth%d:ch24:emac 91: 0 23484 GICv2 71 Level eth%d:ch0:rx_be 92: 0 0 GICv2 72 Level eth%d:ch1:rx_nc 93: 0 13735 GICv2 89 Level eth%d:ch18:tx_be 94: 0 0 GICv2 90 Level eth%d:ch19:tx_nc Worse, on platforms with multiple RAVB instances (e.g. R-Car V4H), all interrupts have similar names. Fix this by using the device name instead, like is done in several other drivers: 89: 0 0 GICv2 93 Level e6800000.ethernet:ch22:multi 90: 0 1 GICv2 95 Level e6800000.ethernet:ch24:emac 91: 0 28578 GICv2 71 Level e6800000.ethernet:ch0:rx_be 92: 0 0 GICv2 72 Level e6800000.ethernet:ch1:rx_nc 93: 0 14044 GICv2 89 Level e6800000.ethernet:ch18:tx_be 94: 0 0 GICv2 90 Level e6800000.ethernet:ch19:tx_nc Rename the local variable dev_name, as it shadows the dev_name() function, and pre-initialize it, to simplify the code.

The CPTS, by design, captures the messageType (Sync, Delay_Req, etc.) field from the second nibble of the PTP header which is defined in the PTPv2 (1588-2008) specification. In the PTPv1 (1588-2002) specification the first two bytes of the PTP header are defined as the versionType which is always 0x0001. This means that any PTPv1 packets that are tagged for TX timestamping by the CPTS will have their messageType set to 0x0 which corresponds to a Sync message type. This causes issues when a PTPv1 stack is expecting a Delay_Req (messageType: 0x1) timestamp that never appears. Fix this by checking if the ptp_class of the timestamped TX packet is PTP_CLASS_V1 and then matching the PTP sequence ID to the stored sequence ID in the skb->cb data structure. If the sequence IDs match and the packet is of type PTPv1 then there is a chance that the messageType has been incorrectly stored by the CPTS so overwrite the messageType stored by the CPTS with the messageType from the skb->cb data structure. This allows the PTPv1 stack to receive TX timestamps for Delay_Req packets which are necessary to lock onto a PTP Leader. Signed-off-by:

Rahul Rameshbabu says: ==================== Fix isolation of broadcast traffic and unmatched unicast traffic with MACsec offload Some device drivers support devices that enable them to annotate whether a Rx skb refers to a packet that was processed by the MACsec offloading functionality of the device. Logic in the Rx handling for MACsec offload does not utilize this information to preemptively avoid forwarding to the macsec netdev currently. Because of this, things like multicast messages or unicast messages with an unmatched destination address such as ARP requests are forwarded to the macsec netdev whether the message received was MACsec encrypted or not. The goal of this patch series is to improve the Rx handling for MACsec offload for devices capable of annotating skbs received that were decrypted by the NIC offload for MACsec. Here is a summary of the issue that occurs with the existing logic today. * The current design of the MACsec offload handling path tries to use "best guess" mechanisms for determining whether a packet associated with the currently handled skb in the datapath was processed via HW offload * The best guess mechanism uses the following heuristic logic (in order of precedence) - Check if header destination MAC address matches MACsec netdev MAC address -> forward to MACsec port - Check if packet is multicast traffic -> forward to MACsec port - MACsec security channel was able to be looked up from skb offload context (mlx5 only) -> forward to MACsec port * Problem: plaintext traffic can potentially solicit a MACsec encrypted response from the offload device - Core aspect of MACsec is that it identifies unauthorized LAN connections and excludes them from communication + This behavior can be seen when not enabling offload for MACsec - The offload behavior violates this principle in MACsec I believe this behavior is a security bug since applications utilizing MACsec could be exploited using this behavior, and the correct way to resolve this is by having the hardware correctly indicate whether MACsec offload occurred for the packet or not. In the patches in this series, I leave a warning for when the problematic path occurs because I cannot figure out a secure way to fix the security issue that applies to the core MACsec offload handling in the Rx path without breaking MACsec offload for other vendors. Shown at the bottom is an example use case where plaintext traffic sent to a physical port of a NIC configured for MACsec offload is unable to be handled correctly by the software stack when the NIC provides awareness to the kernel about whether the received packet is MACsec traffic or not. In this specific example, plaintext ARP requests are being responded with MACsec encrypted ARP replies (which leads to routing information being unable to be built for the requester).

Can now correctly identify where the packets should be delivered by using md_dst or its absence on devices that provide it. This detection is not possible without device drivers that update md_dst. A fallback pattern should be used for supporting such device drivers. This fallback mode causes multicast messages to be cloned to both the non-macsec and macsec ports, independent of whether the multicast message received was encrypted over MACsec or not. Other non-macsec traffic may also fail to be handled correctly for devices in promiscuous mode.

Additional clean-up further propagated this issue, partially breaking the clock gating fixes added for GC7000 rev 6202 in commit 432f51e7 ("drm/etnaviv: add clock gating workaround for GC7000 r6202").

The DP83869 driver sets the MII bit (needed for PHY to work in MII mode) only if the op-mode is either DP83869_100M_MEDIA_CONVERT or DP83869_RGMII_100_BASE. Some drivers i.e. ICSSG support MII mode with op-mode as DP83869_RGMII_COPPER_ETHERNET for which the MII bit is not set in dp83869 driver. As a result MII mode on ICSSG doesn't work and below log is seen.

I added OOM and netpoll discard counters, naively assuming that the cpr pointer is pointing to a common completion ring. Turns out that is usually *a* completion ring but not *the* completion ring which bnapi->cp_ring points to. bnapi->cp_ring is where the stats are read from, so we end up reporting 0 thru ethtool -S and qstat even though the drop events have happened. Make 100% sure we're recording statistics in the correct structure. Fixes: 907fd4a2 ("bnxt: count discards due to memory allocation errors") Reviewed-by:

Roman reports a deadlock on unplug of a Thunderbolt docking station containing an Intel I225 Ethernet adapter. The root cause is that led_classdev's for LEDs on the adapter are registered such that they're device-managed by the netdev. That results in recursive acquisition of the rtnl_lock() mutex on unplug: When the driver calls unregister_netdev(), it acquires rtnl_lock(), then frees the device-managed resources. Upon unregistering the LEDs, netdev_trig_deactivate() invokes unregister_netdevice_notifier(), which tries to acquire rtnl_lock() again. Avoid by using non-device-managed LED registration.
