mainline inclusion from mainline-master commit d9069dab category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I4M1HB CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=d9069dab2075 ---------------------------------------------------------------------- When the mbx or reset message arrives, the driver is informed through an interrupt. This task can be processed only after the workqueue is scheduled. In some cases, this workqueue scheduling takes a long time. As a result, the mbx or reset service task cannot be processed in time. So add some warning message to improve debugging efficiency for this case.

This reverts commit 2c896fb0 "net: stmmac: dwmac-rk: add pd_gmac support for rk3399" and fixes unbalanced pm_runtime_enable warnings. In the commit to be reverted, support for power management was introduced to the Rockchip glue code. Later, power management support was introduced to the stmmac core code, resulting in multiple invocations of pm_runtime_{enable,disable,get_sync,put_sync}. The multiple invocations happen in rk_gmac_powerup and stmmac_{dvr_probe, resume} as well as in rk_gmac_powerdown and stmmac_{dvr_remove, suspend}, respectively, which are always called in conjunction.

stable inclusion from stable-5.10.81 commit 3afe11be6435e126f1507ddf1a9d0e5a0d90b336 bugzilla: 185832 https://gitee.com/openeuler/kernel/issues/I4L9CF Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=3afe11be6435e126f1507ddf1a9d0e5a0d90b336 -------------------------------- commit 5ec55823 upstream. This patch intends to add clocks management for stmmac driver: If CONFIG_PM enabled: 1. Keep clocks disabled after driver probed. 2. Enable clocks when up the net device, and disable clocks when down the net device. If CONFIG_PM disabled: Keep clocks always enabled after driver probed. Note: 1. It is fine for ethtool, since the way of implementing ethtool_ops::begin in stmmac is only can be accessed when interface is enabled, so the clocks are ticked. 2. The MDIO bus has a different life cycle to the MAC, need ensure clocks are enabled when _mdio_read/write() need clocks, because these functions can be called while the interface it not opened. Stable backport notes: When run below command to remove ethernet driver on stratix10 platform, there will be warning trace as below: $ cd /sys/class/net/eth0/device/driver/ $ echo ff800000.ethernet > unbind WARNING: CPU: 3 PID: 386 at drivers/clk/clk.c:810 clk_core_unprepare+0x114/0x274 Modules linked in: sch_fq_codel CPU: 3 PID: 386 Comm: sh Tainted: G W 5.10.74-yocto-standard #1 Hardware name: SoCFPGA Stratix 10 SoCDK (DT) pstate: 00000005 (nzcv daif -PAN -UAO -TCO BTYPE=--) pc : clk_core_unprepare+0x114/0x274 lr : clk_core_unprepare+0x114/0x274 sp : ffff800011bdbb10 clk_core_unprepare+0x114/0x274 clk_unprepare+0x38/0x50 stmmac_remove_config_dt+0x40/0x80 stmmac_pltfr_remove+0x64/0x80 platform_drv_remove+0x38/0x60 ... .. el0_sync_handler+0x1a4/0x1b0 el0_sync+0x180/0x1c0 This issue is introduced by introducing upstream commit 8f269102 ("net: stmmac: disable clocks in stmmac_remove_config_dt()") But in latest mainline kernel, there is no this issue.

stable inclusion from stable-5.10.80 commit d83832d4a838e94282205b565c9c411d00ebceee bugzilla: 185821 https://gitee.com/openeuler/kernel/issues/I4L7CG Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=d83832d4a838e94282205b565c9c411d00ebceee -------------------------------- [ Upstream commit b385cca4 ] When a VF is removed and/or reset its Tx queues need to be stopped from the PF. This is done by calling the ice_dis_vf_qs() function, which calls ice_vsi_stop_lan_tx_rings(). Currently ice_dis_vf_qs() is protected by the VF state bit ICE_VF_STATE_QS_ENA. Unfortunately, this is causing the Tx queues to not be disabled in some cases and when the VF tries to re-enable/reconfigure its Tx queues over virtchnl the op is failing. This is because a VF can be reset and/or removed before the ICE_VF_STATE_QS_ENA bit is set, but the Tx queues were already configured via ice_vsi_cfg_single_txq() in the VIRTCHNL_OP_CONFIG_VSI_QUEUES op. However, the ICE_VF_STATE_QS_ENA bit is set on a successful VIRTCHNL_OP_ENABLE_QUEUES, which will always happen after the VIRTCHNL_OP_CONFIG_VSI_QUEUES op. This was causing the following error message when loading the ice driver, creating VFs, and modifying VF trust in an endless loop: [35274.192484] ice 0000:88:00.0: Failed to set LAN Tx queue context, error: ICE_ERR_PARAM [35274.193074] ice 0000:88:00.0: VF 0 failed opcode 6, retval: -5 [35274.193640] iavf 0000:88:01.0: PF returned error -5 (IAVF_ERR_PARAM) to our request 6 Fix this by always calling ice_dis_vf_qs() and silencing the error message in ice_vsi_stop_tx_ring() since the calling code ignores the return anyway. Also, all other places that call ice_vsi_stop_tx_ring() catch the error, so this doesn't affect those flows since there was no change to the values the function returns. Other solutions were considered (i.e. tracking which VF queues had been "started/configured" in VIRTCHNL_OP_CONFIG_VSI_QUEUES, but it seemed more complicated than it was worth. This solution also brings in the chance for other unexpected conditions due to invalid state bit checks. So, the proposed solution seemed like the best option since there is no harm in failing to stop Tx queues that were never started. This issue can be seen using the following commands: for i in {0..50}; do rmmod ice modprobe ice sleep 1 echo 1 > /sys/class/net/ens785f0/device/sriov_numvfs echo 1 > /sys/class/net/ens785f1/device/sriov_numvfs ip link set ens785f1 vf 0 trust on ip link set ens785f0 vf 0 trust on sleep 2 echo 0 > /sys/class/net/ens785f0/device/sriov_numvfs echo 0 > /sys/class/net/ens785f1/device/sriov_numvfs sleep 1 echo 1 > /sys/class/net/ens785f0/device/sriov_numvfs echo 1 > /sys/class/net/ens785f1/device/sriov_numvfs ip link set ens785f1 vf 0 trust on ip link set ens785f0 vf 0 trust on done Fixes: 77ca27c4 ("ice: add support for virtchnl_queue_select.[tx|rx]_queues bitmap") Signed-off-by: NBrett Creeley <brett.creeley@intel.com> Tested-by: NKonrad Jankowski <konrad0.jankowski@intel.com> Signed-off-by: NTony Nguyen <anthony.l.nguyen@intel.com> Signed-off-by: NSasha Levin <sashal@kernel.org> Signed-off-by: NChen Jun <chenjun102@huawei.com> Reviewed-by: NWeilong Chen <chenweilong@huawei.com> Acked-by: NWeilong Chen <chenweilong@huawei.com> Signed-off-by: NChen Jun <chenjun102@huawei.com> Signed-off-by: NZheng Zengkai <zhengzengkai@huawei.com>

With this change, it is possible that we may get several calls to ibmvnic_xmit() that simply discard packets and return. But if we stop the queue here, we might end up doing so just after __ibmvnic_open() started the queues (during a hard/soft reset) and before the ->resetting bit was cleared. If that happens, there will be no one to restart queue and transmissions will be blocked indefinitely. This can cause a TIMEOUT reset and with auto priority failover enabled, an unnecessary FAILOVER reset to less favored backing device and then a FAILOVER back to the most favored backing device. If we hit the window repeatedly, we can get stuck in a loop of TIMEOUT, FAILOVER, FAILOVER resets leaving the adapter unusable for extended periods of time.

But even if we reduce batch sizes, there would still be cases where the estimated count of orphans is beyond the limit, and where tcp_too_many_orphans() has to call the expensive percpu_counter_sum_positive(). One solution is to use plain per-cpu counters, and have a timer to periodically refresh this cache. Updating this cache every 100ms seems about right, tcp pressure state is not radically changing over shorter periods. percpu_counter was nice 15 years ago while hosts had less than 16 cpus, not anymore by current standards. v2: Fix the build issue for CONFIG_CRYPTO_DEV_CHELSIO_TLS=m, reported by kernel test robot <lkp@intel.com> Remove unused socket argument from tcp_too_many_orphans() Fixes: dd24c001 ("net: Use a percpu_counter for orphan_count") Signed-off-by: NEric Dumazet <edumazet@google.com> Reported-by: NStefan Bach <sfb@google.com> Cc: Neal Cardwell <ncardwell@google.com> Acked-by: NNeal Cardwell <ncardwell@google.com> Signed-off-by: NDavid S.

stable inclusion from stable-5.10.80 commit e519acba2faeca5259fe7126850a28ff76500819 bugzilla: 185821 https://gitee.com/openeuler/kernel/issues/I4L7CG Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=e519acba2faeca5259fe7126850a28ff76500819 -------------------------------- [ Upstream commit c62041c5 ] The 1/10GbaseT modes were set up for cards with SFP+ cages in 3497ed8c ("sfc: report supported link speeds on SFP connections"). 10GbaseT was likely used since no 10G fibre mode existed. The missing fibre modes for 1/10G were added to ethtool.h in 5711a982 ("net: ethtool: add support for 1000BaseX and missing 10G link modes") shortly thereafter. The user guide available at https://support-nic.xilinx.com/wp/drivers lists support for the following cable and transceiver types in section 2.9: - QSFP28 100G Direct Attach Cables - QSFP28 100G SR Optical Transceivers (with SR4 modules listed) - SFP28 25G Direct Attach Cables - SFP28 25G SR Optical Transceivers - QSFP+ 40G Direct Attach Cables - QSFP+ 40G Active Optical Cables - QSFP+ 40G SR4 Optical Transceivers - QSFP+ to SFP+ Breakout Direct Attach Cables - QSFP+ to SFP+ Breakout Active Optical Cables - SFP+ 10G Direct Attach Cables - SFP+ 10G SR Optical Transceivers - SFP+ 10G LR Optical Transceivers - SFP 1000BASE‐T Transceivers - 1G Optical Transceivers (From user guide issue 28. Issue 16 which also includes older cards like SFN5xxx/SFN6xxx has matching lists for 1/10/40G transceiver types.) Regarding SFP+ 10GBASE‐T transceivers the latest guide says: "Solarflare adapters do not support 10GBASE‐T transceiver modules." Tested using SFN5122F-R7 (with 2 SFP+ ports). Supported link modes do not change depending on module used (tested with 1000BASE-T, 1000BASE-BX10, 10GBASE-LR).

mainline inclusion from mainline commit b922f622 bugzilla: 185788 https://e.gitee.com/open_euler/dashboard?issue=I4IYTG CVE: CVE-2021-43975 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=b922f622592af76b57cbc566eaeccda0b31a3496 -------------------------------- This bug report shows up when running our research tools. The reports is SOOB read, but it seems SOOB write is also possible a few lines below. In details, fw.len and sw.len are inputs coming from io. A len over the size of self->rpc triggers SOOB. The patch fixes the bugs by adding sanity checks. The bugs are triggerable with compromised/malfunctioning devices. They are potentially exploitable given they first leak up to 0xffff bytes and able to overwrite the region later. The patch is tested with QEMU emulater. This is NOT tested with a real device. Attached is the log we found by fuzzing.
