[PATCH OLK-6.6] drivers/perf: hisi: Clarifying event names and fix event ID for pa_pmu
by Yushan Wang 16 Jun '25

16 Jun '25

From: Junhao He <hejunhao3(a)huawei.com> driver inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ICFG22 ---------------------------------------------------------------------- The rx_req and tx_req events were only counting the number of flit package requests for link0. Hisilicon PA supports 4 links (0-3), and the original event names could be misinterpreted as counting the total flit packages across all links. Additionally, the tx_req event ID was incorrect. Fixes this by: 1) Adding the "link0" suffix and "pa" prefix to the event names to clearly indicate that they are specific to link0 and belong to the PA PMU. 2) Updating the tx_req event ID to 0x60 to reflect the correct identifier. These changes ensure accurate event naming and counting for link0 and flit packages.

From: Jann Horn <jannh(a)google.com> stable inclusion from stable-v5.10.235 commit 90dd2f1b7342b9a671a5ea4160f408037b92b118 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBO4LT CVE: CVE-2025-21704 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit e563b01208f4d1f609bcab13333b6c0e24ce6a01 upstream. If the first fragment is shorter than struct usb_cdc_notification, we can't calculate an expected_size. Log an error and discard the notification instead of reading lengths from memory outside the received data, which can lead to memory corruption when the expected_size decreases between fragments, causing `expected_size - acm->nb_index` to wrap. This issue has been present since the beginning of git history; however, it only leads to memory corruption since commit ea2583529cd1 ("cdc-acm: reassemble fragmented notifications"). A mitigating factor is that acm_ctrl_irq() can only execute after userspace has opened /dev/ttyACM*; but if ModemManager is running, ModemManager will do that automatically depending on the USB device's vendor/product IDs and its other interfaces.
