[PATCH OLK-6.6] net: lan743x: fix potential out-of-bounds write in lan743x_ptp_io_event_clock_get()
by Dong Chenchen 27 Aug '25

From: Alexey Kodanev <aleksei.kodanev(a)bell-sw.com> stable inclusion from stable-v6.6.95 commit 66bba1fd5bad548c03f7e42669a59f3f4d8211cc category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICK4NT CVE: CVE-2025-38183 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit e353b0854d3a1a31cb061df8d022fbfea53a0f24 ] Before calling lan743x_ptp_io_event_clock_get(), the 'channel' value is checked against the maximum value of PCI11X1X_PTP_IO_MAX_CHANNELS(8). This seems correct and aligns with the PTP interrupt status register (PTP_INT_STS) specifications. However, lan743x_ptp_io_event_clock_get() writes to ptp->extts[] with only LAN743X_PTP_N_EXTTS(4) elements, using channel as an index: lan743x_ptp_io_event_clock_get(..., u8 channel,...) { ... /* Update Local timestamp */ extts = &ptp->extts[channel]; extts->ts.tv_sec = sec; ... } To avoid an out-of-bounds write and utilize all the supported GPIO inputs, set LAN743X_PTP_N_EXTTS to 8. Detected using the static analysis tool - Svace.

After calling bpf_exec_tx_verdict(), the size of msg_pl->sg may increase, e.g., when the BPF program executes bpf_msg_push_data(). If the BPF program sets cork_bytes and sg.size is smaller than cork_bytes, it will return -ENOSPC and attempt to roll back to the non-zero copy logic. However, during rollback, msg->msg_iter is reset, but since msg_pl->sg.size has been increased, subsequent executions will exceed the actual size of msg_iter. ''' iov_iter_revert(&msg->msg_iter, msg_pl->sg.size - orig_size); ''' The changes in this commit are based on the following considerations: 1. When cork_bytes is set, rolling back to non-zero copy logic is pointless and can directly go to zero-copy logic. 2. We can not calculate the correct number of bytes to revert msg_iter. Assume the original data is "abcdefgh" (8 bytes), and after 3 pushes by the BPF program, it becomes 11-byte data: "abc?de?fgh?". Then, we set cork_bytes to 6, which means the first 6 bytes have been processed, and the remaining 5 bytes "?fgh?" will be cached until the length meets the cork_bytes requirement. However, some data in "?fgh?" is not within 'sg->msg_iter' (but in msg_pl instead), especially the data "?" we pushed. So it doesn't seem as simple as just reverting through an offset of msg_iter. 3. For non-TLS sockets in tcp_bpf_sendmsg, when a "cork" situation occurs, the user-space send() doesn't return an error, and the returned length is the same as the input length parameter, even if some data is cached. Additionally, I saw that the current non-zero-copy logic for handling corking is written as: ''' line 1177 else if (ret != -EAGAIN) { if (ret == -ENOSPC) ret = 0; goto send_end; ''' So it's ok to just return 'copied' without error when a "cork" situation occurs.

A previous commit(see Fixes tag) introduced skb_get() to avoid race conditions between skb operations in the backlog and skb release in the recvmsg path. However, this caused the panic to always occur when skb_linearize is executed. The "--rx-strp 100000" parameter forces the RX path to use the strparser module which aggregates data until it reaches 100KB before calling sockmap logic. The 100KB payload exceeds MAX_MSG_FRAGS, triggering skb_linearize. To fix this issue, just move skb_get into sk_psock_skb_ingress_enqueue.

[PATCH OLK-6.6] net/mlx5e: Disable MACsec offload for uplink representor profile

When switching to the uplink representor profile, the MACsec offload feature must be cleared from the netdevice's features.

From: Ido Schimmel <idosch(a)nvidia.com> stable inclusion from stable-v6.6.92 commit f1ecccb5cdda39bca8cd17bb0b6cf61361e33578 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICGALB CVE: CVE-2025-38019 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 92ec4855034b2c4d13f117558dc73d20581fa9ff ] The driver only offloads neighbors that are constructed on top of net devices registered by it or their uppers (which are all Ethernet). The device supports GRE encapsulation and decapsulation of forwarded traffic, but the driver will not offload dummy neighbors constructed on top of GRE net devices as they are not uppers of its net devices: # ip link add name gre1 up type gre tos inherit local 192.0.2.1 remote 198.51.100.1 # ip neigh add 0.0.0.0 lladdr 0.0.0.0 nud noarp dev gre1 $ ip neigh show dev gre1 nud noarp 0.0.0.0 lladdr 0.0.0.0 NOARP (Note that the neighbor is not marked with 'offload') When the driver is reloaded and the existing configuration is replayed, the driver does not perform the same check regarding existing neighbors and offloads the previously added one: # devlink dev reload pci/0000:01:00.0 $ ip neigh show dev gre1 nud noarp 0.0.0.0 lladdr 0.0.0.0 offload NOARP If the neighbor is later deleted, the driver will ignore the notification (given the GRE net device is not its upper) and will therefore keep referencing freed memory, resulting in a use-after-free [1] when the net device is deleted: # ip neigh del 0.0.0.0 lladdr 0.0.0.0 dev gre1 # ip link del dev gre1 Fix by skipping neighbor replay if the net device for which the replay is performed is not our upper.

The root cause is: the function ib_device_rename() renames the name with lock. But in the function kobject_uevent(), this name is accessed without lock protection at the same time. The solution is to add the lock protection when this name is accessed in the function kobject_uevent().

[PATCH OLK-6.6] dmaengine: ti: k3-udma-glue: Drop skip_fdq argument from k3_udma_glue_reset_rx_chn
by Dong Chenchen 27 Aug '25

27 Aug '25

From: Roger Quadros <rogerq(a)kernel.org> mainline inclusion from mainline-v6.15-rc1 commit 0da30874729baeb01889b0eca16cfda122687503 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICGAII CVE: CVE-2025-38042 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- The user of k3_udma_glue_reset_rx_chn() e.g. ti_am65_cpsw_nuss can run on multiple platforms having different DMA architectures. On some platforms there can be one FDQ for all flows in the RX channel while for others there is a separate FDQ for each flow in the RX channel. So far we have been relying on the skip_fdq argument of k3_udma_glue_reset_rx_chn(). Instead of relying on the user to provide this information, infer it based on DMA architecture during k3_udma_glue_request_rx_chn() and save it in an internal flag 'single_fdq'. Use that flag at k3_udma_glue_reset_rx_chn() to deicide if the FDQ needs to be cleared for every flow or just for flow 0.

[PATCH OLK-6.6] can: bcm: add locking for bcm_op runtime updates
by Dong Chenchen 27 Aug '25

27 Aug '25

From: Oliver Hartkopp <socketcan(a)hartkopp.net> stable inclusion from stable-v6.6.93 commit 76c84c3728178b2d38d5604e399dfe8b0752645e category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICDJW9 CVE: CVE-2025-38004 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit c2aba69d0c36a496ab4f2e81e9c2b271f2693fd7 upstream. The CAN broadcast manager (CAN BCM) can send a sequence of CAN frames via hrtimer. The content and also the length of the sequence can be changed resp reduced at runtime where the 'currframe' counter is then set to zero. Although this appeared to be a safe operation the updates of 'currframe' can be triggered from user space and hrtimer context in bcm_can_tx(). Anderson Nascimento created a proof of concept that triggered a KASAN slab-out-of-bounds read access which can be prevented with a spin_lock_bh. At the rework of bcm_can_tx() the 'count' variable has been moved into the protected section as this variable can be modified from both contexts too.

[PATCH OLK-5.10] thunderbolt: Do not double dequeue a configuration request

Some of our devices crash in tb_cfg_request_dequeue(): general protection fault, probably for non-canonical address 0xdead000000000122 CPU: 6 PID: 91007 Comm: kworker/6:2 Tainted: G U W 6.6.65 RIP: 0010:tb_cfg_request_dequeue+0x2d/0xa0 Call Trace: <TASK> ? tb_cfg_request_dequeue+0x2d/0xa0 tb_cfg_request_work+0x33/0x80 worker_thread+0x386/0x8f0 kthread+0xed/0x110 ret_from_fork+0x38/0x50 ret_from_fork_asm+0x1b/0x30 The circumstances are unclear, however, the theory is that tb_cfg_request_work() can be scheduled twice for a request: first time via frame.callback from ring_work() and second time from tb_cfg_request(). Both times kworkers will execute tb_cfg_request_dequeue(), which results in double list_del() from the ctl->request_queue (the list poison deference hints at it: 0xdead000000000122).

[PATCH OLK-6.6 v2] arm64: Fix actlr_el1 can not set problem in guest
by Jinjie Ruan 27 Aug '25

27 Aug '25

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/release-management/issues/IBV2E4 -------------------------------- During the initialization of the vCPU, the vcpu->arch.hcr_el2 is set to HCR_GUEST_FLAGS, which include HCR_TACR, so regardless of whether the host has configured HCR_EL2, accessing ACTLR_EL1 in the guest virtual machine will trap to EL2. However, the current implementation of KVM ignores writes to ACTLR_EL1, so it is currently not possible to set this register in the guest, hardware xcall/xint can not take effect anyway, so modify the state of actlr based on the written value in access_actlr().

[PATCH OLK-6.6 0/3] Updates of HiSilicon Uncore L3C PMU
by Yushan Wang 26 Aug '25

26 Aug '25

From: Qizhi Zhang <zhangqizhi3(a)h-partners.com> Updates of HiSilicon Uncore L3C PMU --- Support new version of L3C PMU, which supports extended events space which can be controlled in up to 2 extra address spaces with separate overflow interrupts. The layout of the control/event registers are kept the same. The extended events with original ones together cover the monitoring job of all transactions on L3C. That's said, the driver supports finer granual statistics of L3 cache with separated and dedicated PMUs, and a new operand `ext` to give a hint of to which part should perf counting command be delivered. The extended events is specified with `ext=[1|2]` option for the driver to distinguish: perf stat -e hisi_sccl0_l3c0_0/event=<event_id>,ext=<ext>/ Currently only event option using config bit [7, 0]. There's still plenty unused space. Make ext using config [16, 17] and reserve bit [15, 8] for event option for future extension. With the capability of extra counters, number of counters for HiSilicon uncore PMU could reach up to 24, the usedmap is extended accordingly. The hw_perf_event::event_base is initialized to the base MMIO address of the event and will be used for later control, overflow handling and counts readout. We still make use of the Uncore PMU framework for handling the events and interrupt migration on CPU hotplug. The framework's cpuhp callback will handle the event migration and interrupt migration of orginial event, if PMU supports extended events then the interrupt of extended events is migrated to the same CPU choosed by the framework. A new HID of HISI0215 is used for this version of L3C PMU. Some necessary refactor is included, allowing the framework to cope with the new version of driver.

[PATCH OLK-6.6] arm64: perf: Add support for HIP12 hw metric
by Yushan Wang 26 Aug '25

26 Aug '25

From: Yicong Yang <yangyicong(a)hisilicon.com> driver inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/ICFKG8 ---------------------------------------------------------------------- HIP12 provides hardware metric sampling with adjacent counters counter_2n and counter_2n+1. Overflow of counter_2n+1 will result in an interrupt while overflow of counter_2n will load initial value, which are stored in dedicated registers reload_counter_2n and reload_counter_2n+1, to both counters. With the ability above, software could only perform sampling during handling interrupt of counter_2n and configure different values of reload_counter_2n and reload_counter_2n+1, which realizes hardware metric sampling. For example, perf record -e '\ {armv8_pmuv3_0/cpu_cycles,period=1000000,hw_metric=1/, \ armv8_pmuv3_0/inst_retired,period=800000,hw_metric=1/}:u' \ -- <workload> Above command will only perform sampling when IPC < 800000 / 1000000, since the interrupt will only appear when cpu_cycles reaches 1000000 and inst_retired is less than 800000.

From: Jann Horn <jannh(a)google.com> mainline inclusion from mainline-v6.16-rc1 commit 1013af4f585fccc4d3e5c5824d174de2257f7d6d category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICIQAF CVE: CVE-2025-38085 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- huge_pmd_unshare() drops a reference on a page table that may have previously been shared across processes, potentially turning it into a normal page table used in another process in which unrelated VMAs can afterwards be installed. If this happens in the middle of a concurrent gup_fast(), gup_fast() could end up walking the page tables of another process. While I don't see any way in which that immediately leads to kernel memory corruption, it is really weird and unexpected. Fix it with an explicit broadcast IPI through tlb_remove_table_sync_one(), just like we do in khugepaged when removing page tables for a THP collapse.
