Merge commit cited in fixes tag was incorrect. Due to it phys_port_name of the virtual port resulted in incorrect name. Also the phys_port_name of the physical port was written twice due to the merge error. Fix it by removing the old code and inserting back the misplaced code. Related commits of interest in net and net-next branches that resulted in merge conflict are: in net-next branch: commit f285f37c ("devlink: append split port number to the port name") in net branch: commit b28d8f0c ("devlink: Correct VIRTUAL port to not have phys_port attributes") Fixes: 12628565 ("Merge ra.kernel.org:/pub/scm/linux/kernel/git/netdev/net") Signed-off-by:

In the existing code while changing the number of TX/RX queues using ethtool the PF/VF interface resources are freed and reallocated (otx2_stop and otx2_open is called) if the device is in running state. If any resource allocation fails in otx2_open, driver free already allocated resources and return. But again, when the number of queues changes as the device state still running oxt2_stop is called. In which we try to free already freed resources leading to driver crash. This patch fixes the issue by setting the INTF_DOWN flag on error and free the resources in otx2_stop only if the flag is not set.

Currently PKINDs are not assigned to LBK channels. The default value of LBK_CHX_PKIND (channel to PKIND mapping) register is zero, which is resulting in a overlap of pkind between LBK and CGX LMACs. When KPU1 parser config is modified when PTP timestamping is enabled on the CGX LMAC interface it is impacting traffic on LBK interfaces as well. This patch fixes the issue by reserving the PKIND#0 for LBK devices. CGX mapped PF pkind starts from 1 and also fixes the max pkind available.

We use the timecounter APIs for the 48-bit PHC and packet timestamps. We must periodically update the timecounter at roughly half the overflow interval. The overflow interval is about 78 hours, so update it every 19 hours (1/4 interval) for some extra margins.

One skb's skb_shinfo frags are not writable, and they can be shared with other skbs' like by pskb_copy(). To write the frags may cause other skb's data crash. So before doing en/decryption, skb_cow_data() should always be called for a cloned or nonlinear skb if req dst is using the same sg as req src. While at it, the likely branch can be removed, as it will be covered by skb_cow_data(). Note that esp_input() has the same issue, and I will fix it in another patch. tipc_aead_encrypt() doesn't have this issue, as it only processes linear data in the unlikely branch.

The first patch is by Joakim Zhang targets the imx8mp device tree. It removes the imx6 fallback from the flexcan binding, as the imx6 is not compatible with the imx8mp. Ziyang Xuan contributes a patch to fix a use-after-free in the CAN raw's raw_setsockopt(). The next two patches target the CAN J1939 protocol. The first one is by Oleksij Rempel and clarifies the lifetime of session object in j1939_session_deactivate(). Zhang Changzhong's patch fixes the timeout value between consecutive TP.DT. Stephane Grosjean contributes a patch for the peak_usb driver to fix reading of the rxerr/txerr values. The last patch is by me for the mcp251xfd driver. It stops the timestamp worker in case of a fatal error in the IRQ handler. ==================== Signed-off-by:

In case an error occurred in the IRQ handler, the chip status is dumped via devcoredump and all IRQs are disabled, but the chip stays powered for further analysis. The chip is in an undefined state and will not receive any CAN frames, so shut down the timestamping worker, which reads the TBC register regularly, too. This avoids any CRC read error messages if there is a communication problem with the chip.

The j1939_session_deactivate() is decrementing the session ref-count and potentially can free() the session. This would cause use-after-free situation. However, the code calling j1939_session_deactivate() does always hold another reference to the session, so that it would not be free()ed in this code path. This patch adds a comment to make this clear and a WARN_ON, to ensure that future changes will not violate this requirement. Further this patch avoids dereferencing the session pointer as a precaution to avoid use-after-free if the session is actually free()ed.

If PTP configuration is attempted on ports that don't support it, such as VF ports, the driver will return an error status -95, or EOPNOSUPP and print an error message enp98s0: hwstamp set failed: -95 Because some daemons can retry every few seconds, this can end up filling the dmesg log and pushing out other more useful messages.

Syzbot reported memory leak in qrtr. The problem was in unputted struct sock. qrtr_local_enqueue() function calls qrtr_port_lookup() which takes sock reference if port was found. Then there is the following check: if (!ipc || &ipc->sk == skb->sk) { ... return -ENODEV; } Since we should drop the reference before returning from this function and ipc can be non-NULL inside this if, we should add qrtr_port_put() inside this if. The similar corner case is in qrtr_endpoint_post() as Manivannan reported. In case of sock_queue_rcv_skb() failure we need to put port reference to avoid leaking struct sock pointer.

In cases where the header straight after the tunnel header was another ethernet header (TEB), instead of the network header, the ECN decapsulation code would treat the ethernet header as if it was an IP header, resulting in mishandling and possible wrong drops or corruption of the IP header. In this case, ECT(1) is sent, so IP_ECN_decapsulate tries to copy it to the inner IPv4 header, and correct its checksum. The offset of the ECT bits in an IPv4 header corresponds to the lower 2 bits of the second octet of the destination MAC address in the ethernet header. The IPv4 checksum corresponds to end of the source address.

For implicit-connect, when it's either SYN- or SYN+, an ACK should be sent back to the client immediately. It's not appropriate for the client to enter established state only after receiving data from the server. On client side, after the SYN is sent out, tipc_wait_for_connect() should be called to wait for the ACK if timeout is set. This patch also restricts __tipc_sendstream() to call __sendmsg() only when it's in TIPC_OPEN state, so that the client can program in a single loop doing both connecting and data sending like: for (...) sendmsg(dest, buf); This makes the implicit-connect more implicit.

Remove devm_kfree of memory where VLAN entry to RVU PF mapping info is saved. This will be freed anyway at driver exit. Having this could result in warning from devm_kfree() if the memory is not allocated due to errors in rvu_nix_block_init() before nix_setup_txvlan().

In SW DCB mode the packets sent receive incorrect UP tags. They are constructed correctly and put into tx_ring, but UP is later remapped by HW on the basis of TCTUPR register contents according to Tx queue selected, and BW used is consistent with the new UP values. This is caused by Tx queue selection in kernel not taking into account DCB configuration. This patch fixes the issue by implementing the ndo_select_queue NDO callback.

Make warning meaningful for the user. Previously the trace: "Starting FW LLDP agent failed: error: I40E_ERR_ADMIN_QUEUE_ERROR, I40E_AQ_RC_EAGAIN" was produced when user tried to start Firmware LLDP agent, just after it was stopped with sequence: ethtool --set-priv-flags <dev> disable-fw-lldp on ethtool --set-priv-flags <dev> disable-fw-lldp off (without any delay between the commands) At that point the firmware is still processing stop command, the behavior is expected.

Correct the message flow between driver and firmware when disabling queues. Previously in case of PF reset (due to required reinit after reconfig), the error like: "VSI seid 397 Tx ring 60 disable timeout" could show up occasionally. The error was not a real issue of hardware or firmware, it was caused by wrong sequence of messages invoked by the driver. Fixes: 41c445ff ("i40e: main driver core") Signed-off-by:
