Paul Barker says: ==================== Fix maximum TX/RX frame sizes in ravb driver These patches fix a couple of bugs in the maximum supported TX/RX frame sizes in the ravb driver. * For the GbEth IP, we were advertising a maximum TX frame size/MTU that was larger that the maximum the hardware can transmit. * For the R-Car AVB IP, we were unnecessarily setting the maximum RX frame size/MRU based on the MTU, which by default is smaller than the maximum the hardware can receive. For the R-Car AVB IP, the maximum TX frame size should be 2047 (not 2048), but additional work will be required to validate that change so it is not included in this series. Changes v2->v3: * Pick up Reviewed-by tag and suggested comment improvement from Niklas. Changes v1->v2: * Rebase on net tree as these are both bugfixes. * Pick up Reviewed-by tags. ==================== Link: https://patch.msgid.link/20240918081839.259-1-paul.barker.ct@bp.renesas.comSigned-off-by: -

The RX frame size limit should not be based on the current MTU setting. Instead it should be based on the hardware capabilities. While we're here, improve the description of the receive frame length setting as suggested by Niklas. Fixes: c156633f ("Renesas Ethernet AVB driver proper") Reviewed-by:

The datasheets for all SoCs using the GbEth IP specify a maximum transmission frame size of 1.5 kByte. I've confirmed through internal discussions that support for 1522 byte frames has been validated, which allows us to support the default MTU of 1500 bytes after reserving space for the Ethernet header, frame checksums and an optional VLAN tag.

The commit b8c43360 ("net: stmmac: No need to calculate speed divider when offload is disabled") allows the "port_transmit_rate_kbps" to be set to a value of 0, which is then passed to the "div_s64" function when tc-cbs is disabled. This leads to a zero-division error. When tc-cbs is disabled, the idleslope, sendslope, and credit values the credit values are not required to be configured. Therefore, adding a return statement after setting the txQ mode to DCB when tc-cbs is disabled would prevent a zero-division error.

RTL8125 added fields to the tally counter, what may result in the chip dma'ing these new fields to unallocated memory. Therefore make sure that the allocated memory area is big enough to hold all of the tally counter values, even if we use only parts of it.

for_each_set_bit was used wrongly in aqr107_config_init() when iterating over LEDs. Drop misleading 'index' variable and call aqr_phy_led_active_low_set() for each set bit representing an LED which is driven by VDD instead of GND pin.

When broadcasting data to multiple nodes via MHI, using skb_clone() causes all nodes to receive the same header data. This can result in packets being discarded by endpoints, leading to lost data. This issue occurs when a socket is closed, and a QRTR_TYPE_DEL_CLIENT packet is broadcasted. All nodes receive the same destination node ID, causing the node connected to the client to discard the packet and remain unaware of the client's deletion. Replace skb_clone() with pskb_copy(), to create a separate copy of the header for each sk_buff. Fixes: bdabad3e ("net: Add Qualcomm IPC router") Signed-off-by:

We have some machines running stock Ubuntu 20.04.6 which is their 5.4.0-174-generic kernel that are running ceph and recently hit a null ptr dereference in tcp_rearm_rto(). Initially hitting it from the TLP path, but then later we also saw it getting hit from the RACK case as well. Here are examples of the oops messages we saw in each of those cases: Jul 26 15:05:02 rx [11061395.780353] BUG: kernel NULL pointer dereference, address: 0000000000000020 Jul 26 15:05:02 rx

attempting to pull an skb off the head of the retransmit queue and then dereferencing that skb to get the skb_mstamp_ns value via tcp_skb_timestamp_us(skb). The crash is the same one that was reported a # of years ago here: https://lore.kernel.org/netdev/86c0f836-9a7c-438b-d81a-839be45f1f58@gmail.com/T/#t and the kernel we're running has the fix which was added to resolve this issue. Unfortunately we've been unsuccessful so far in reproducing this problem in the lab and do not have the luxury of pushing out a new kernel to try and test if newer kernels resolve this issue at the moment. I realize this is a report against both an Ubuntu kernel and also an older 5.4 kernel. I have reported this issue to Ubuntu here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2077657 however I feel like since this issue has possibly cropped up again it makes sense to build in some protection in this path (even on the latest kernel versions) since the code in question just blindly assumes there's a valid skb without testing if it's NULL b/f it looks at the timestamp. Given we have seen crashes in this path before and now this case it seems like we should protect ourselves for when packets_out accounting is incorrect. While we should fix that root cause we should also just make sure the skb is not NULL before dereferencing it. Also add a warn once here to capture some information if/when the problem case is hit again. Fixes: e1a10ef7 ("tcp: introduce tcp_rto_delta_us() helper for xmit timer fix") Signed-off-by:

Commit aa58bec0 ("net: ethernet: oa_tc6: implement register write operation") adds two new file entries to OPEN ALLIANCE 10BASE-T1S MACPHY SERIAL INTERFACE FRAMEWORK. One of the two entries mistakenly refers to drivers/include/linux/oa_tc6.h, whereas the intent is clearly to refer to include/linux/oa_tc6.h. Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a broken reference. Adjust the file entry to the intended location. Signed-off-by:

In the ether3_probe function, a timer is initialized with a callback function ether3_ledoff, bound to &prev(dev)->timer. Once the timer is started, there is a risk of a race condition if the module or device is removed, triggering the ether3_remove function to perform cleanup. The sequence of operations that may lead to a UAF bug is as follows: CPU0 CPU1 | ether3_ledoff ether3_remove | free_netdev(dev); | put_devic | kfree(dev); | | ether3_outw(priv(dev)->regs.config2 |= CFG2_CTRLO, REG_CONFIG2); | // use dev Fix it by ensuring that the timer is canceled before proceeding with the cleanup in ether3_remove.

axienet_free_tx_chain returns the number of DMA descriptors it's handled. However, axienet_tx_poll treats the return as the number of packets. When scatter-gather SKBs are enabled, a single packet may use multiple DMA descriptors, which causes incorrect packet counts. Fix this by explicitly keepting track of the number of packets processed as separate from the DMA descriptors. Budget does not affect the number of Tx completions we can process for NAPI, so we use the ring size as the limit instead of budget. As we no longer return the number of descriptors processed to axienet_tx_poll, we now update tx_bd_ci in axienet_free_tx_chain.

The author of the blamed commit apparently did not notice something about aqr_wait_reset_complete(): it polls the exact same register - MDIO_MMD_VEND1:VEND1_GLOBAL_FW_ID - as aqr_firmware_load(). Thus, the entire logic after the introduction of aqr_wait_reset_complete() is now completely side-stepped, because if aqr_wait_reset_complete() succeeds, MDIO_MMD_VEND1:VEND1_GLOBAL_FW_ID could have only been a non-zero value. The handling of the case where the register reads as 0 is dead code, due to the previous -ETIMEDOUT having stopped execution and returning a fatal error to the caller. We never attempt to load new firmware if no firmware is present. Based on static code analysis, I guess we should simply introduce a switch/case statement based on the return code from aqr_wait_reset_complete(), to determine whether to load firmware or not. I am not intending to change the procedure through which the driver determines whether to load firmware or not, as I am unaware of alternative possibilities. At the same time, Russell King suggests that if aqr_wait_reset_complete() is expected to return -ETIMEDOUT as part of normal operation and not just catastrophic failure, the use of phy_read_mmd_poll_timeout() is improper, since that has an embedded print inside. Just open-code a call to read_poll_timeout() to avoid printing -ETIMEDOUT, but continue printing actual read errors from the MDIO bus.

Pull networking updates from Jakub Kicinski: "The zero-copy changes are relatively significant, but regression risk should be contained. The feature needs to be used to cause trouble. Also it feels like we got an order of magnitude more semi-automated "refactoring" chaff than usual, I wonder if it's just us. Core & protocols: - Support Device Memory TCP, ability to zero-copy receive TCP payloads to a DMABUF region of memory while packet headers land separately in normal kernel buffers, and TCP processes then as usual. - The ability to read the PTP PHC (Physical Hardware Clock) alongside MONOTONIC_RAW timestamps with PTP_SYS_OFFSET_EXTENDED. Previously only CLOCK_REALTIME was supported. - Allow matching on all bits of IP DSCP for routing decisions. Previously we only supported on matching TOS bits in IPv4 which is a narrower interpretation of the same header field. - Increase the range of weights used for multi-path routing from 8 bits to 16 bits. - Add support for IPv6 PIO p flag in the Prefix Information Option per draft-ietf-6man-pio-pflag. - IPv6 IOAM6 support for new tunsrc encap mode for better performance. - Detect destinations which blackhole MPTCP traffic and avoid initiating MPTCP connections to them for a certain period of time, 1h by default. - Improve IPsec control path performance by removing the inexact policies list. - AF_VSOCK: add support for SIOCOUTQ ioctl. - Add enum for reasons TCP reset was sent for easier tracing. - Add SMC ringbufs usage statistics. Drivers: - Handle netconsole setup failures more gracefully, don't fail loading, retain the specified target as disabled. - Extend bonding's IPsec offload pass thru capabilities (ESN, stats). Filtering: - Add TCP_BPF_SOCK_OPS_CB_FLAGS to bpf_*sockopt() to address the case when long-lived sockets miss a chance to set additional callbacks if a sockops program was not attached early in their lifetime. - Support using BPF skb helpers in tracepoints. - Conntrack Netlink: support CTA_FILTER for flush. - Improve SCTP support in nfnetlink_queue. - Improve performance of large nftables flush transactions. Things we sprinkled into general kernel code: - selftests: support setting an "interpreter" for script files; make it easy to run as separate cases tests where one "interpreter" is fed various test descriptions (in our case packet sequences). Driver API: - Extend core and ethtool APIs to support many PHYs connected to a single interface (PHY topologies). - Extend cable diagnostics to specify whether Time Domain Reflectometry (TDR) or Active Link Cable Diagnostic (ALCD) was used. - Add library for implementing MAC-PHY Ethernet drivers for SPI devices compatible with Open Alliance 10BASE-T1x MAC-PHY Serial Interface (TC6) standard. - Add helpers to the PHY framework, for PHYs following the Open Alliance standards: - 1000BaseT1 link settings - cable test and diagnostics - Support listing / dumping all allocated RSS contexts. - Add configuration for frequency Embedded SYNC in DPLL, which magically embeds sync pulses into Ethernet signaling.

Paolo Bonzini authored
This reverts commit 377b2f35. This caused a regression with the bochsdrm driver, which used ioremap() instead of ioremap_wc() to map the video RAM. After the commit, the WB memory type is used without the IGNORE_PAT, resulting in the slower UC memory type. In fact, UC is slow enough to basically cause guests to not boot... but only on new processors such as Sapphire Rapids and Cascade Lake. Coffee Lake for example works properly, though that might also be an effect of being on a larger, more NUMA system. The driver has been fixed but that does not help older guests. Until we figure out whether Cascade Lake and newer processors are working as intended, revert the commit. Long term we might add a quirk, but the details depend on whether the processors are working as intended: for example if they are, the quirk might reference bochs-compatible devices, e.g. in the name and documentation, so that userspace can disable the quirk by default and only leave it enabled if such a device is being exposed to the guest. If instead this is actually a bug in CLX+, then the actions we need to take are different and depend on the actual cause of the bug. Signed-off-by:

MD Danish Anwar says: ==================== Introduce HSR offload support for ICSSG This series introduces HSR offload support for ICSSG driver. To support HSR offload to hardware, ICSSG HSR firmware is used. This series introduces, 1. HSR frame offload support for ICSSG driver. 2. HSR Tx Packet duplication offload 3. HSR Tx Tag and Rx Tag offload 4. Multicast filtering support in HSR offload mode. 5. Dependencies related to IEP. HSR Test Setup: -------------- ___________ ___________ ___________ | | Link AB | | Link BC | | __| AM64* |_________| AM64 |_________| AM64* |___ | | Station A | | Station B | | Station C | | | |___________| |___________| |___________| | | | |______________________________________________________________| Link CA *Could be any device that supports two ethernet interfaces. Steps to switch to HSR frame forward offload mode: ------------------------------------------------- Example assuming eth1, eth2 ports of ICSSG1 on AM64-EVM 1) Enable HSR offload for both interfaces ethtool -K eth1 hsr-fwd-offload on ethtool -K eth1 hsr-dup-offload on ethtool -K eth1 hsr-tag-ins-offload on ethtool -K eth1 hsr-tag-rm-offload on ethtool -K eth2 hsr-fwd-offload on ethtool -K eth2 hsr-dup-offload on ethtool -K eth2 hsr-tag-ins-offload on ethtool -K eth2 hsr-tag-rm-offload on 2) Create HSR interface and add slave interfaces to it ip link add name hsr0 type hsr slave1 eth1 slave2 eth2 \ supervision 45 version 1 3) Add IP address to the HSR interface ip addr add <IP_ADDR>/24 dev hsr0 4) Bring up the HSR interface ip link set hsr0 up Switching back to previous mode: -------------------------------- 1) Delete HSR interface ip link delete hsr0 2) Disable HSR port-to-port offloading mode, packet duplication ethtool -K eth1 hsr-fwd-offload off ethtool -K eth1 hsr-dup-offload off ethtool -K eth1 hsr-tag-ins-offload off ethtool -K eth1 hsr-tag-rm-offload off ethtool -K eth2 hsr-fwd-offload off ethtool -K eth2 hsr-dup-offload off ethtool -K eth2 hsr-tag-ins-offload off ethtool -K eth2 hsr-tag-rm-offload off Testing the port-to-port frame forward offload feature: ----------------------------------------------------- 1) Connect the LAN cables as shown in the test setup. 2) Configure Station A and Station C in HSR non-offload mode. 3) Configure Station B is HSR offload mode. 4) Since HSR is a redundancy protocol, disconnect cable "Link CA", to ensure frames from Station A reach Station C only through Station B. 5) Run iperf3 Server on Station C and client on station A. 7) Check the CPU usage on Station B. CPU usage report on Station B using mpstat when running UDP iperf3: ------------------------------------------------------------------- 1) Non-Offload case ------------------- CPU %usr %nice %sys %iowait %irq %soft %steal %guest %idle all 0.00 0.00 0.50 0.00 3.52 29.15 0.00 0.00 66.83 0 0.00 0.00 0.00 0.00 7.00 58.00 0.00 0.00 35.00 1 0.00 0.00 0.99 0.00 0.99 0.00 0.00 0.00 98.02 2) Offload case --------------- CPU %usr %nice %sys %iowait %irq %soft %steal %guest %idle all 0.00 0.00 0.00 0.00 0.50 0.00 0.00 0.00 99.50 0 0.00 0.00 0.99 0.00 0.00 0.00 0.00 0.00 99.01 1 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 100.00 Note: 1) At the very least, hsr-fwd-offload must be enabled.

The HSR stack allows to offload its Tx packet duplication functionality to the hardware. Enable this offloading feature for ICSSG driver. Add support to offload HSR Tx Tag Insertion and Rx Tag Removal and duplicate discard. hsr tag insertion offload and hsr dup offload are tightly coupled in firmware implementation. Both these features need to be enabled / disabled together. Duplicate discard is done as part of RX tag removal and it is done by the firmware. When driver sends the r30 command ICSSG_EMAC_HSR_RX_OFFLOAD_ENABLE, firmware does RX tag removal as well as duplicate discard. Signed-off-by:

Add support for offloading HSR port-to-port frame forward to hardware. When the slave interfaces are added to the HSR interface, the PRU cores will be stopped and ICSSG HSR firmwares will be loaded to them. Similarly, when HSR interface is deleted, the PRU cores will be restarted and the last used firmwares will be reloaded. PRUeth interfaces will be back to the last used mode. This commit also renames some APIs that are common between switch and hsr mode with '_fw_offload' suffix. Signed-off-by:
