From: Zhen Lei <thunder.leizhen(a)huawei.com> hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I545H8 CVE: NA ------------------------------------------------------------------------- To be consistent with the style of other ARCHs such as x86, the kexec commit b5a34a20984c ("arm64: support more than one crash kernel regions") requires all crash regions to be named "Crash kernel". Update the name of crashk_low_res, so that we can directly use the latest kexec tool without having to maintain a private version.

[PATCH openEuler-5.10 01/13] ixgbe: add the ability for the PF to disable VF link state
by Zheng Zengkai 27 Apr '22

27 Apr '22

From: Slawomir Mrozowicz <slawomirx.mrozowicz(a)intel.com> mainline inclusion from mainline-v5.18-rc1 commit 366fd1000995d4cf64e1a61a0d78a051550b9841 category: bugfix bugzilla: 186597, https://gitee.com/src-openeuler/kernel/issues/I532H9 CVE: CVE-2021-33061 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Add support for ndo_set_vf_link_state the Network Device Option that allows the PF driver to control the virtual link state of the VF devices. Without this change a VF cannot be disabled/enabled by the administrator. In the implementation the auto state takes over PF link state to VF link setting, the enable state is not supported, the disable state shut off the VF link regardless of the PF setting.

[PATCH openEuler-5.10 01/42] can: usb_8dev: usb_8dev_start_xmit(): fix double dev_kfree_skb() in error path
by Zheng Zengkai 27 Apr '22

27 Apr '22

From: Hangyu Hua <hbh25y(a)gmail.com> stable inclusion from stable-v5.10.110 commit 5318cdf4fd834856ce71238b064f35386f9ef528 category: bugfix bugzilla: 186592 https://gitee.com/src-openeuler/kernel/issues/I51YBQ?from=project-issue CVE: CVE-2022-28388 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 3d3925ff6433f98992685a9679613a2cc97f3ce2 upstream. There is no need to call dev_kfree_skb() when usb_submit_urb() fails because can_put_echo_skb() deletes original skb and can_free_echo_skb() deletes the cloned skb.

[PATCH openEuler-1.0-LTS] x86/tsc: Make cur->adjusted values in package#1 to be the same
by LeoLiuoc 26 Apr '22

26 Apr '22

zhaoxin inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I54V2W CVE: NA ---------------------------------------------------------------- When resume from S4 on Zhaoxin 2 packages platform that support X86_FEATURE_TSC_ADJUST, the following warning messages appear: [ 327.445302] [Firmware Bug]: TSC ADJUST differs: CPU15 45960750 --> 78394770. Restoring [ 329.209120] [Firmware Bug]: TSC ADJUST differs: CPU14 45960750 --> 78394770. Restoring [ 329.209128] [Firmware Bug]: TSC ADJUST differs: CPU13 45960750 --> 78394770. Restoring [ 329.209138] [Firmware Bug]: TSC ADJUST differs: CPU12 45960750 --> 78394770. Restoring [ 329.209151] [Firmware Bug]: TSC ADJUST differs: CPU11 45960750 --> 78394770. Restoring [ 329.209160] [Firmware Bug]: TSC ADJUST differs: CPU10 45960750 --> 78394770. Restoring [ 329.209169] [Firmware Bug]: TSC ADJUST differs: CPU9 45960750 --> 78394770. Restoring The reason is: Step 1: Bring up. TSC is sync after bring up with following settings: MSR 0x3b cur->adjusted Package#0 CPU 0-7 0 0 Package#1 first CPU value1 value1 Package#1 non-first CPU value1 value1 Step 2: Suspend to S4. Settings in Step 1 are not changed in this Step. Step 3: Bring up caused by S4 wake up event. TSC is sync when bring up with following settings: MSR 0x3b cur->adjusted Package#0 CPU 0-7 0 0 Package#1 first CPU value2 value2 Package#1 non-first CPU value2 value2 Step 4: Resume from S4. When resuming from S4, Current TSC synchronous mechanism cause following settings: MSR 0x3b cur->adjusted Package#0 CPU 0-7 0 0 Package#1 first CPU value2 value2 Package#1 non-first CPU value2 value1 In these Steps, value1 != 0 and value2 != value1. In Step4, as function tsc_store_and_check_tsc_adjust() do, when the value of MSR 0x3b on the non-first online CPU in package#1 is equal to the value of cur->adjusted on the first online CPU in the same package, the cur->adjusted value on this non-first online CPU will hold the old value1. This cause function tsc_verify_tsc_adjust() set the value of MSR 0x3b on the non-first online CPUs in the package#1 to the old value1 and print the beginning warning messages. Fix it by setting cur->adjusted value on the non-first online CPU in a package to the value of MSR 0x3b on the same CPU when they are not equal.

[PATCH openEuler-1.0-LTS] XHCI:Fix some device identify fail when enable xHCI runtime suspend
by LeoLiuoc 26 Apr '22

26 Apr '22

zhaoxin inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I54V16 CVE: NA ---------------------------------------------------------------- If plug out device form xhci with runtime suspend enabled. On the one hand, driver will disconnect this device and send disabled slot command to xhci. On the other hand, without no device connect to xhci, PM core will call xhci suspend function to let xhci go to D3 to save power. However there is a temporal competition to get xhci lock between disable slot command interrupt and xhci suspend. If xhci suspend function get xhci lock first, then this function will clear xhci command ring. It will get error command trb when driver to handle disable slot command interrupt. This is a serious error for driver and driver will cleanup xhci. So，any device connect to this xhci port again will not be recognized. In order to fix this issues, we let disable slot command interrupt ISR to get xhci lock first. So, add a delay in xhci suspend function before to get xhci lock.
