From: Baihan Li <libaihan(a)huawei.com> Realizing the basic display function of DP cable for DP connector displaying. Add DP module in hibmc drm driver, which is for Hisilicon Hibmc SoC which used for Out-of-band management. Blow is the general hardware connection, both the Hibmc and the host CPU are on the same mother board. +----------+ +----------+ +----- ----+ +----------------+ | | PCIe | Hibmc | | | | | |host CPU( |<----->| display |<---->| dp kapi |<---->| dp aux moduel | |arm64,x86)| |subsystem | | moduel |<---->| dp link moduel | +----------+ +----------+ +----------+ +----------------+ Baihan Li (5): drm/hisilicon/hibmc: add dp aux in hibmc drivers drm/hisilicon/hibmc: add dp link moduel in hibmc drivers drm/hisilicon/hibmc: add dp hw moduel in hibmc driver drm/hisilicon/hibmc: refactored struct hibmc_drm_private drm/hisilicon/hibmc: add dp module in hibmc Jani Nikula (1): drm/hisilicon/hibmc: convert to struct drm_edid drivers/gpu/drm/hisilicon/hibmc/Makefile | 3 +- drivers/gpu/drm/hisilicon/hibmc/dp/dp_aux.c | 164 +++++++++ drivers/gpu/drm/hisilicon/hibmc/dp/dp_comm.h | 63 ++++ .../gpu/drm/hisilicon/hibmc/dp/dp_config.h | 19 + drivers/gpu/drm/hisilicon/hibmc/dp/dp_hw.c | 220 ++++++++++++ drivers/gpu/drm/hisilicon/hibmc/dp/dp_hw.h | 28 ++ drivers/gpu/drm/hisilicon/hibmc/dp/dp_link.c | 332 ++++++++++++++++++ drivers/gpu/drm/hisilicon/hibmc/dp/dp_reg.h | 76 ++++ .../gpu/drm/hisilicon/hibmc/hibmc_drm_dp.c | 118 +++++++ .../gpu/drm/hisilicon/hibmc/hibmc_drm_drv.c | 14 + .../gpu/drm/hisilicon/hibmc/hibmc_drm_drv.h | 19 +- .../gpu/drm/hisilicon/hibmc/hibmc_drm_i2c.c | 42 ++- .../gpu/drm/hisilicon/hibmc/hibmc_drm_vdac.c | 33 +- 13 files changed, 1085 insertions(+), 46 deletions(-) create mode 100644 drivers/gpu/drm/hisilicon/hibmc/dp/dp_aux.c create mode 100644 drivers/gpu/drm/hisilicon/hibmc/dp/dp_comm.h create mode 100644 drivers/gpu/drm/hisilicon/hibmc/dp/dp_config.h create mode 100644 drivers/gpu/drm/hisilicon/hibmc/dp/dp_hw.c create mode 100644 drivers/gpu/drm/hisilicon/hibmc/dp/dp_hw.h create mode 100644 drivers/gpu/drm/hisilicon/hibmc/dp/dp_link.c create mode 100644 drivers/gpu/drm/hisilicon/hibmc/dp/dp_reg.h create mode 100644 drivers/gpu/drm/hisilicon/hibmc/hibmc_drm_dp.c -- 2.33.0

[PATCH openEuler-1.0-LTS] dlm: fix plock invalid read
by Xia Fukun 14 Mar '25

14 Mar '25

From: Alexander Aring <aahringo(a)redhat.com> stable inclusion from stable-v4.19.247 commit 5a1765adf9855cf0f6d3f7e0eb4b78ca66f70dee category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP3TG CVE: CVE-2022-49407 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 42252d0d2aa9b94d168241710a761588b3959019 upstream. This patch fixes an invalid read showed by KASAN. A unlock will allocate a "struct plock_op" and a followed send_op() will append it to a global send_list data structure. In some cases a followed dev_read() moves it to recv_list and dev_write() will cast it to "struct plock_xop" and access fields which are only available in those structures. At this point an invalid read happens by accessing those fields. To fix this issue the "callback" field is moved to "struct plock_op" to indicate that a cast to "plock_xop" is allowed and does the additional "plock_xop" handling if set. Example of the KASAN output which showed the invalid read: [ 2064.296453] ================================================================== [ 2064.304852] BUG: KASAN: slab-out-of-bounds in

[PATCH openEuler-1.0-LTS] mm: fix unexpected zeroed page mapping with zram swap
by Liu Shixin 14 Mar '25

14 Mar '25

From: Minchan Kim <minchan(a)kernel.org> stable inclusion from stable-v4.19.242 commit f86d55cf616199404c05f5b0c5c41b17351baa02 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP28G CVE: CVE-2022-49052 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit e914d8f00391520ecc4495dd0ca0124538ab7119 upstream. Two processes under CLONE_VM cloning, user process can be corrupted by seeing zeroed page unexpectedly. CPU A CPU B do_swap_page do_swap_page SWP_SYNCHRONOUS_IO path SWP_SYNCHRONOUS_IO path swap_readpage valid data swap_slot_free_notify delete zram entry swap_readpage zeroed(invalid) data pte_lock map the *zero data* to userspace pte_unlock pte_lock if (!pte_same) goto out_nomap; pte_unlock return and next refault will read zeroed data The swap_slot_free_notify is bogus for CLONE_VM case since it doesn't increase the refcount of swap slot at copy_mm so it couldn't catch up whether it's safe or not to discard data from backing device. In the case, only the lock it could rely on to synchronize swap slot freeing is page table lock. Thus, this patch gets rid of the swap_slot_free_notify function. With this patch, CPU A will see correct data. CPU A CPU B do_swap_page do_swap_page SWP_SYNCHRONOUS_IO path SWP_SYNCHRONOUS_IO path swap_readpage original data pte_lock map the original data swap_free swap_range_free bd_disk->fops->swap_slot_free_notify swap_readpage read zeroed data pte_unlock pte_lock if (!pte_same) goto out_nomap; pte_unlock return on next refault will see mapped data by CPU B The concern of the patch would increase memory consumption since it could keep wasted memory with compressed form in zram as well as uncompressed form in address space. However, most of cases of zram uses no readahead and do_swap_page is followed by swap_free so it will free the compressed form from in zram quickly.

[PATCH OLK-5.10] PCI: rcar-ep: Fix incorrect variable used when calling devm_request_mem_region()

From: King Dix <kingdix10(a)qq.com> mainline inclusion from mainline-v6.14-rc1 commit 2d2da5a4c1b4509f6f7e5a8db015cd420144beb4 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBPLK2 CVE: CVE-2025-21804 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- The rcar_pcie_parse_outbound_ranges() uses the devm_request_mem_region() macro to request a needed resource. A string variable that lives on the stack is then used to store a dynamically computed resource name, which is then passed on as one of the macro arguments. This can lead to undefined behavior. Depending on the current contents of the memory, the manifestations of errors may vary. One possible output may be as follows: $ cat /proc/iomem 30000000-37ffffff : 38000000-3fffffff : Sometimes, garbage may appear after the colon. In very rare cases, if no NULL-terminator is found in memory, the system might crash because the string iterator will overrun which can lead to access of unmapped memory above the stack. Thus, fix this by replacing outbound_name with the name of the previously requested resource.

[PATCH OLK-6.6] hrtimers: Force migrate away hrtimers queued after CPUHP_AP_HRTIMERS_DYING
by Xiongfeng Wang 13 Mar '25

13 Mar '25

From: Frederic Weisbecker <frederic(a)kernel.org> mainline inclusion from mainline-v6.14-rc2 commit 53dac345395c0d2493cbc2f4c85fe38aef5b63f5 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBPLI0 CVE: CVE-2025-21816 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- hrtimers are migrated away from the dying CPU to any online target at the CPUHP_AP_HRTIMERS_DYING stage in order not to delay bandwidth timers handling tasks involved in the CPU hotplug forward progress. However wakeups can still be performed by the outgoing CPU after CPUHP_AP_HRTIMERS_DYING. Those can result again in bandwidth timers being armed. Depending on several considerations (crystal ball power management based election, earliest timer already enqueued, timer migration enabled or not), the target may eventually be the current CPU even if offline. If that happens, the timer is eventually ignored. The most notable example is RCU which had to deal with each and every of those wake-ups by deferring them to an online CPU, along with related workarounds: _ e787644caf76 (rcu: Defer RCU kthreads wakeup when CPU is dying) _ 9139f93209d1 (rcu/nocb: Fix RT throttling hrtimer armed from offline CPU) _ f7345ccc62a4 (rcu/nocb: Fix rcuog wake-up from offline softirq) The problem isn't confined to RCU though as the stop machine kthread (which runs CPUHP_AP_HRTIMERS_DYING) reports its completion at the end of its work through cpu_stop_signal_done() and performs a wake up that eventually arms the deadline server timer: WARNING: CPU: 94 PID: 588 at kernel/time/hrtimer.c:1086 hrtimer_start_range_ns+0x289/0x2d0 CPU: 94 UID: 0 PID: 588 Comm: migration/94 Not tainted Stopper: multi_cpu_stop+0x0/0x120 <- stop_machine_cpuslocked+0x66/0xc0 RIP: 0010:hrtimer_start_range_ns+0x289/0x2d0 Call Trace: <TASK> start_dl_timer enqueue_dl_entity dl_server_start enqueue_task_fair enqueue_task ttwu_do_activate try_to_wake_up complete cpu_stopper_thread Instead of providing yet another bandaid to work around the situation, fix it in the hrtimers infrastructure instead: always migrate away a timer to an online target whenever it is enqueued from an offline CPU. This will also allow to revert all the above RCU disgraceful hacks.

[PATCH OLK-6.6] iommufd/iova_bitmap: Fix shift-out-of-bounds in iova_bitmap_offset_to_index()

The constant "1" defaults to a 32-bit "int", and when "pgshift" exceeds 31 (e.g., pgshift = 63) the shift operation overflows, as the result cannot be represented in a 32-bit type. To resolve this, the constant is updated to "1UL", promoting it to an unsigned long type to match the operand's type.

[PATCH OLK-6.6] PCI: dwc: ep: Prevent changing BAR size/flags in pci_epc_set_bar()
by Xiongfeng Wang 13 Mar '25

13 Mar '25

From: Niklas Cassel <cassel(a)kernel.org> mainline inclusion from mainline-v6.14-rc1 commit 3708acbd5f169ebafe1faa519cb28adc56295546 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBPC3J CVE: CVE-2024-58006 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- In commit 4284c88fff0e ("PCI: designware-ep: Allow pci_epc_set_bar() update inbound map address") set_bar() was modified to support dynamically changing the backing physical address of a BAR that was already configured. This means that set_bar() can be called twice, without ever calling clear_bar() (as calling clear_bar() would clear the BAR's PCI address assigned by the host). This can only be done if the new BAR size/flags does not differ from the existing BAR configuration. Add these missing checks. If we allow set_bar() to set e.g. a new BAR size that differs from the existing BAR size, the new address translation range will be smaller than the BAR size already determined by the host, which would mean that a read past the new BAR size would pass the iATU untranslated, which could allow the host to read memory not belonging to the new struct pci_epf_bar. While at it, add comments which clarifies the support for dynamically changing the physical address of a BAR. (Which was also missing.)

[PATCH OLK-6.6] afs: Fix the maximum cell name length

From: David Howells <dhowells(a)redhat.com> mainline inclusion from mainline-v6.13-rc7 commit 8fd56ad6e7c90ac2bddb0741c6b248c8c5d56ac8 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBIQQL CVE: CVE-2025-21646 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- The kafs filesystem limits the maximum length of a cell to 256 bytes, but a problem occurs if someone actually does that: kafs tries to create a directory under /proc/net/afs/ with the name of the cell, but that fails with a warning: WARNING: CPU: 0 PID: 9 at fs/proc/generic.c:405 because procfs limits the maximum filename length to 255. However, the DNS limits the maximum lookup length and, by extension, the maximum cell name, to 255 less two (length count and trailing NUL). Fix this by limiting the maximum acceptable cellname length to 253. This also allows us to be sure we can create the "/afs/.<cell>/" mountpoint too. Further, split the YFS VL record cell name maximum to be the 256 allowed by the protocol and ignore the record retrieved by YFSVL.GetCellName if it exceeds 253.

[PATCH openEuler-1.0-LTS] powerpc/pseries: Fix use after free in remove_phb_dynamic()
by Qi Xi 13 Mar '25

13 Mar '25

From: Michael Ellerman <mpe(a)ellerman.id.au> mainline inclusion from mainline-v5.18-rc1 commit fe2640bd7a62f1f7c3f55fbda31084085075bc30 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP1SK CVE: CVE-2022-49196 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- In remove_phb_dynamic() we use &phb->io_resource, after we've called device_unregister(&host_bridge->dev). But the unregister may have freed phb, because pcibios_free_controller_deferred() is the release function for the host_bridge. If there are no outstanding references when we call device_unregister() then phb will be freed out from under us. This has gone mainly unnoticed, but with slub_debug and page_poison enabled it can lead to a crash: PID: 7574 TASK: c0000000d492cb80 CPU: 13 COMMAND: "drmgr" #0 [c0000000e4f075a0] crash_kexec at c00000000027d7dc #1 [c0000000e4f075d0] oops_end at c000000000029608 #2 [c0000000e4f07650] __bad_page_fault at c0000000000904b4 #3 [c0000000e4f076c0] do_bad_slb_fault at c00000000009a5a8 #4 [c0000000e4f076f0] data_access_slb_common_virt at c000000000008b30 Data SLB Access [380] exception frame: R0: c000000000167250 R1: c0000000e4f07a00 R2: c000000002a46100 R3: c000000002b39ce8 R4: 00000000000000c0 R5: 00000000000000a9 R6: 3894674d000000c0 R7: 0000000000000000 R8: 00000000000000ff R9: 0000000000000100 R10: 6b6b6b6b6b6b6b6b R11: 0000000000008000 R12: c00000000023da80 R13: c0000009ffd38b00 R14: 0000000000000000 R15: 000000011c87f0f0 R16: 0000000000000006 R17: 0000000000000003 R18: 0000000000000002 R19: 0000000000000004 R20: 0000000000000005 R21: 000000011c87ede8 R22: 000000011c87c5a8 R23: 000000011c87d3a0 R24: 0000000000000000 R25: 0000000000000001 R26: c0000000e4f07cc8 R27: c00000004d1cc400 R28: c0080000031d00e8 R29: c00000004d23d800 R30: c00000004d1d2400 R31: c00000004d1d2540 NIP: c000000000167258 MSR: 8000000000009033 OR3: c000000000e9f474 CTR: 0000000000000000 LR: c000000000167250 XER: 0000000020040003 CCR: 0000000024088420 MQ: 0000000000000000 DAR: 6b6b6b6b6b6b6ba3 DSISR: c0000000e4f07920 Syscall Result: fffffffffffffff2 [NIP : release_resource+56] [LR : release_resource+48] #5 [c0000000e4f07a00] release_resource at c000000000167258 (unreliable) #6 [c0000000e4f07a30] remove_phb_dynamic at c000000000105648 #7 [c0000000e4f07ab0] dlpar_remove_slot at c0080000031a09e8 [rpadlpar_io] #8 [c0000000e4f07b50] remove_slot_store at c0080000031a0b9c [rpadlpar_io] #9 [c0000000e4f07be0] kobj_attr_store at c000000000817d8c #10 [c0000000e4f07c00] sysfs_kf_write at c00000000063e504 #11 [c0000000e4f07c20] kernfs_fop_write_iter at c00000000063d868 #12 [c0000000e4f07c70] new_sync_write at c00000000054339c #13 [c0000000e4f07d10] vfs_write at c000000000546624 #14 [c0000000e4f07d60] ksys_write at c0000000005469f4 #15 [c0000000e4f07db0] system_call_exception at c000000000030840 #16 [c0000000e4f07e10] system_call_vectored_common at c00000000000c168 To avoid it, we can take a reference to the host_bridge->dev until we're done using phb.

[PATCH OLK-6.6 v2 1/2] fuse: cleanup request queuing towards virtiofs
by Yang Erkun 13 Mar '25

13 Mar '25

From: Miklos Szeredi <mszeredi(a)redhat.com> mainline inclusion from mainline-v6.12-rc1 commit 5de8acb41c86f1d335d165e0a350441ea3a1f480 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBT4CQ Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- Virtiofs has its own queuing mechanism, but still requests are first queued on fiq->pending to be immediately dequeued and queued onto the virtio queue. The queuing on fiq->pending is unnecessary and might even have some performance impact due to being a contention point. Forget requests are handled similarly. Move the queuing of requests and forgets into the fiq->ops->*. fuse_iqueue_ops are renamed to reflect the new semantics.

[PATCH OLK-5.10] scsi: lpfc: Fix null pointer dereference after failing to issue FLOGI and PLOGI
by Guo Mengqi 13 Mar '25

13 Mar '25

From: James Smart <jsmart2021(a)gmail.com> mainline inclusion from mainline-v5.19-rc1 commit 577a942df3de2666f6947bdd3a5c9e8d30073424 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP6SH CVE: CVE-2022-49535 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- [ Upstream commit 577a942df3de2666f6947bdd3a5c9e8d30073424 ] If lpfc_issue_els_flogi() fails and returns non-zero status, the node reference count is decremented to trigger the release of the nodelist structure. However, if there is a prior registration or dev-loss-evt work pending, the node may be released prematurely. When dev-loss-evt completes, the released node is referenced causing a use-after-free null pointer dereference. Similarly, when processing non-zero ELS PLOGI completion status in lpfc_cmpl_els_plogi(), the ndlp flags are checked for a transport registration before triggering node removal. If dev-loss-evt work is pending, the node may be released prematurely and a subsequent call to lpfc_dev_loss_tmo_handler() results in a use after free ndlp dereference. Add test for pending dev-loss before decrementing the node reference count for FLOGI, PLOGI, PRLI, and ADISC handling.

[PATCH openEuler-1.0-LTS] net: mdio: unexport __init-annotated mdio_bus_init()

From: Masahiro Yamada <masahiroy(a)kernel.org> stable inclusion from stable-v4.19.247 commit 5534bcd7c40299862237c4a8fd9c5031b3db1538 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBPK8Q CVE: CVE-2022-49350 Reference: https://web.git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit… -------------------------------- [ Upstream commit 35b42dce619701f1300fb8498dae82c9bb1f0263 ] EXPORT_SYMBOL and __init is a bad combination because the .init.text section is freed up after the initialization. Hence, modules cannot use symbols annotated __init. The access to a freed symbol may end up with kernel panic. modpost used to detect it, but it has been broken for a decade. Recently, I fixed modpost so it started to warn it again, then this showed up in linux-next builds. There are two ways to fix it: - Remove __init - Remove EXPORT_SYMBOL I chose the latter for this case because the only in-tree call-site, drivers/net/phy/phy_device.c is never compiled as modular. (CONFIG_PHYLIB is boolean) Fixes: 90eff9096c01 ("net: phy: Allow splitting MDIO bus/device support from PHYs") Reported-by: Stephen Rothwell <sfr(a)canb.auug.org.au> Signed-off-by: Masahiro Yamada <masahiroy(a)kernel.org> Reviewed-by: Florian Fainelli <f.fainelli(a)gmail.com> Reviewed-by: Russell King (Oracle) <rmk+kernel(a)armlinux.org.uk> Signed-off-by: Jakub Kicinski <kuba(a)kernel.org> Signed-off-by: Sasha Levin <sashal(a)kernel.org> Signed-off-by: Wenyu Huang <huangwenyu5(a)huawei.com> --- drivers/net/phy/mdio_bus.c | 1 - 1 file changed, 1 deletion(-) diff --git a/drivers/net/phy/mdio_bus.c b/drivers/net/phy/mdio_bus.c index 82cc1983c09a..35937175c4e8 100644 --- a/drivers/net/phy/mdio_bus.c +++ b/drivers/net/phy/mdio_bus.c @@ -745,7 +745,6 @@ int __init mdio_bus_init(void) return ret; } -EXPORT_SYMBOL_GPL(mdio_bus_init); #if IS_ENABLED(CONFIG_PHYLIB) void mdio_bus_exit(void) -- 2.34.1

From: Jessica Zhang <quic_jesszhan(a)quicinc.com> stable inclusion from stable-v4.19.247 commit 776f5c58bfe16cf322d71eeed3c5dda1eeac7e6b category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP1O4 CVE: CVE-2022-49490 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit d59be579fa932c46b908f37509f319cbd4ca9a68 ] mdp5_get_global_state runs the risk of hitting a -EDEADLK when acquiring the modeset lock, but currently mdp5_pipe_release doesn't check for if an error is returned. Because of this, there is a possibility of mdp5_pipe_release hitting a NULL dereference error. To avoid this, let's have mdp5_pipe_release check if mdp5_get_global_state returns an error and propogate that error. Changes since v1: - Separated declaration and initialization of *new_state to avoid compiler warning - Fixed some spelling mistakes in commit message Changes since v2: - Return 0 in case where hwpipe is NULL as this is considered normal behavior - Added 2nd patch in series to fix a similar NULL dereference issue in mdp5_mixer_release Reported-by: Tomeu Vizoso <tomeu.vizoso(a)collabora.com> Signed-off-by: Jessica Zhang <quic_jesszhan(a)quicinc.com> Fixes: 7907a0d77cb4 ("drm/msm/mdp5: Use the new private_obj state") Reviewed-by: Rob Clark <robdclark(a)gmail.com> Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov(a)linaro.org> Patchwork: https://patchwork.freedesktop.org/patch/485179/ Link: https://lore.kernel.org/r/20220505214051.155-1-quic_jesszhan@quicinc.com Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov(a)linaro.org> Signed-off-by: Sasha Levin <sashal(a)kernel.org> Signed-off-by: Zeng Heng <zengheng4(a)huawei.com> --- drivers/gpu/drm/msm/disp/mdp5/mdp5_pipe.c | 15 +++++++++++---- drivers/gpu/drm/msm/disp/mdp5/mdp5_pipe.h | 2 +- drivers/gpu/drm/msm/disp/mdp5/mdp5_plane.c | 20 ++++++++++++++++---- 3 files changed, 28 insertions(+), 9 deletions(-) diff --git a/drivers/gpu/drm/msm/disp/mdp5/mdp5_pipe.c b/drivers/gpu/drm/msm/disp/mdp5/mdp5_pipe.c index 1ef26bc63163..88de12225582 100644 --- a/drivers/gpu/drm/msm/disp/mdp5/mdp5_pipe.c +++ b/drivers/gpu/drm/msm/disp/mdp5/mdp5_pipe.c @@ -130,18 +130,23 @@ int mdp5_pipe_assign(struct drm_atomic_state *s, struct drm_plane *plane, return 0; } -void mdp5_pipe_release(struct drm_atomic_state *s, struct mdp5_hw_pipe *hwpipe) +int mdp5_pipe_release(struct drm_atomic_state *s, struct mdp5_hw_pipe *hwpipe) { struct msm_drm_private *priv = s->dev->dev_private; struct mdp5_kms *mdp5_kms = to_mdp5_kms(to_mdp_kms(priv->kms)); struct mdp5_global_state *state = mdp5_get_global_state(s); - struct mdp5_hw_pipe_state *new_state = &state->hwpipe; + struct mdp5_hw_pipe_state *new_state; if (!hwpipe) - return; + return 0; + + if (IS_ERR(state)) + return PTR_ERR(state); + + new_state = &state->hwpipe; if (WARN_ON(!new_state->hwpipe_to_plane[hwpipe->idx])) - return; + return -EINVAL; DBG("%s: release from plane %s", hwpipe->name, new_state->hwpipe_to_plane[hwpipe->idx]->name); @@ -152,6 +157,8 @@ void mdp5_pipe_release(struct drm_atomic_state *s, struct mdp5_hw_pipe *hwpipe) } new_state->hwpipe_to_plane[hwpipe->idx] = NULL; + + return 0; } void mdp5_pipe_destroy(struct mdp5_hw_pipe *hwpipe) diff --git a/drivers/gpu/drm/msm/disp/mdp5/mdp5_pipe.h b/drivers/gpu/drm/msm/disp/mdp5/mdp5_pipe.h index bb2b0ac7aa2b..072db6a99b85 100644 --- a/drivers/gpu/drm/msm/disp/mdp5/mdp5_pipe.h +++ b/drivers/gpu/drm/msm/disp/mdp5/mdp5_pipe.h @@ -48,7 +48,7 @@ int mdp5_pipe_assign(struct drm_atomic_state *s, struct drm_plane *plane, uint32_t caps, uint32_t blkcfg, struct mdp5_hw_pipe **hwpipe, struct mdp5_hw_pipe **r_hwpipe); -void mdp5_pipe_release(struct drm_atomic_state *s, struct mdp5_hw_pipe *hwpipe); +int mdp5_pipe_release(struct drm_atomic_state *s, struct mdp5_hw_pipe *hwpipe); struct mdp5_hw_pipe *mdp5_pipe_init(enum mdp5_pipe pipe, uint32_t reg_offset, uint32_t caps); diff --git a/drivers/gpu/drm/msm/disp/mdp5/mdp5_plane.c b/drivers/gpu/drm/msm/disp/mdp5/mdp5_plane.c index 1ddf07514de6..85bbae26b17e 100644 --- a/drivers/gpu/drm/msm/disp/mdp5/mdp5_plane.c +++ b/drivers/gpu/drm/msm/disp/mdp5/mdp5_plane.c @@ -399,12 +399,24 @@ static int mdp5_plane_atomic_check_with_state(struct drm_crtc_state *crtc_state, mdp5_state->r_hwpipe = NULL; - mdp5_pipe_release(state->state, old_hwpipe); - mdp5_pipe_release(state->state, old_right_hwpipe); + ret = mdp5_pipe_release(state->state, old_hwpipe); + if (ret) + return ret; + + ret = mdp5_pipe_release(state->state, old_right_hwpipe); + if (ret) + return ret; + } } else { - mdp5_pipe_release(state->state, mdp5_state->hwpipe); - mdp5_pipe_release(state->state, mdp5_state->r_hwpipe); + ret = mdp5_pipe_release(state->state, mdp5_state->hwpipe); + if (ret) + return ret; + + ret = mdp5_pipe_release(state->state, mdp5_state->r_hwpipe); + if (ret) + return ret; + mdp5_state->hwpipe = mdp5_state->r_hwpipe = NULL; } -- 2.25.1

From: Hristo Venev <hristo(a)venev.name> stable inclusion from stable-v4.19.254 commit 8ff4f9df73e5c551a72ee6034886c17e8de6596d category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP6VF CVE: CVE-2022-49581 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit d7241f679a59cfe27f92cb5c6272cb429fb1f7ec ] be_cmd_read_port_transceiver_data assumes that it is given a buffer that is at least PAGE_DATA_LEN long, or twice that if the module supports SFF 8472. However, this is not always the case. Fix this by passing the desired offset and length to be_cmd_read_port_transceiver_data so that we only copy the bytes once.

[PATCH OLK-6.6] perf: Configure BRBE correctly on VHE host
by Yushan Wang 12 Mar '25

12 Mar '25

From: Yicong Yang <yangyicong(a)hisilicon.com> driver inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBSI0M CVE: NA ---------------------------------------------------------------------- The BRBE support backported of v18 didn't configure the BRBCR_EL1 correctly which will miss some key functions like FZP during sampling. In VHE mode with MDCR_EL2.HPMN set to PMCR_EL0.N, the counters are controlled by BRBCR_EL1 rather than BRBCR_EL2 (which writes to BRBCR_EL1 are redirected to). Use the same value for both register except keep EL1 and EL0 recording disabled in guests. The fix is backported from the v19 version [1].

[PATCH openEuler-1.0-LTS] sfc: fix kernel panic when creating VF

From: Íñigo Huguet <ihuguet(a)redhat.com> stable inclusion from stable-v4.19.253 commit 82bcb730f856086f033e6c04082eb4503d4c2fa4 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP5WM CVE: CVE-2022-49625 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit ada74c5539eba06cf8b47d068f92e0b3963a9a6e ] When creating VFs a kernel panic can happen when calling to efx_ef10_try_update_nic_stats_vf. When releasing a DMA coherent buffer, sometimes, I don't know in what specific circumstances, it has to unmap memory with vunmap. It is disallowed to do that in IRQ context or with BH disabled. Otherwise, we hit this line in vunmap, causing the crash: BUG_ON(in_interrupt()); This patch reenables BH to release the buffer.

[PATCH OLK-5.10] RDMA/hns: Fix mbox timing out by adding retry mechanism
by Junxian Huang 12 Mar '25

12 Mar '25

maillist inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBSLDS CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma.git/commit/?h=wip… ---------------------------------------------------------------------- If a QP is modified to error state and a flush CQE process is triggered, the subsequent QP destruction mbox can still be successfully posted but will be blocked in HW until the flush CQE process finishes. This causes further mbox posting timeouts in driver. The blocking time is related to QP depth. Considering an extreme case where SQ depth and RQ depth are both 32K, the blocking time can reach about 135ms. This patch adds a retry mechanism for mbox posting. For each try, FW waits 15ms for HW to complete the previous mbox, otherwise return a timeout error code to driver. Counting other time consumption in FW, set 8 tries for mbox posting and a 5ms time gap before each retry to increase to a sufficient timeout limit.

[PATCH OLK-6.6] perf: Configure BRBE correctly on VHE host
by Yushan Wang 12 Mar '25

12 Mar '25

From: Yicong Yang <yangyicong(a)hisilicon.com> driver inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBSI0M CVE: NA ---------------------------------------------------------------------- The BRBE support backported of v18 didn't configure the BRBCR_EL1 correctly which will miss some key functions like FZP during sampling. In VHE mode with MDCR_EL2.HPMN set to PMCR_EL0.N, the counters are controlled by BRBCR_EL1 rather than BRBCR_EL2 (which writes to BRBCR_EL1 are redirected to). Use the same value for both register except keep EL1 and EL0 recording disabled in guests. The fix is backported from the v19 version [1].

[PATCH openEuler-1.0-LTS] hrtimers: Handle CPU state correctly on hotplug
by Zeng Heng 11 Mar '25

11 Mar '25

From: Koichiro Den <koichiro.den(a)canonical.com> stable inclusion from stable-v6.6.74 commit a5cbbea145b400e40540c34816d16d36e0374fbc category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBLWTN CVE: CVE-2024-57951 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 2f8dea1692eef2b7ba6a256246ed82c365fdc686 upstream. Consider a scenario where a CPU transitions from CPUHP_ONLINE to halfway through a CPU hotunplug down to CPUHP_HRTIMERS_PREPARE, and then back to CPUHP_ONLINE: Since hrtimers_prepare_cpu() does not run, cpu_base.hres_active remains set to 1 throughout. However, during a CPU unplug operation, the tick and the clockevents are shut down at CPUHP_AP_TICK_DYING. On return to the online state, for instance CFS incorrectly assumes that the hrtick is already active, and the chance of the clockevent device to transition to oneshot mode is also lost forever for the CPU, unless it goes back to a lower state than CPUHP_HRTIMERS_PREPARE once. This round-trip reveals another issue; cpu_base.online is not set to 1 after the transition, which appears as a WARN_ON_ONCE in enqueue_hrtimer(). Aside of that, the bulk of the per CPU state is not reset either, which means there are dangling pointers in the worst case. Address this by adding a corresponding startup() callback, which resets the stale per CPU state and sets the online flag.

[PATCH] RDMA/hns: Fix mbox timing out by adding retry mechanism
by Junxian Huang 11 Mar '25

11 Mar '25

maillist inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBSLDS CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma.git/commit/?h=wip… ---------------------------------------------------------------------- If a QP is modified to error state and a flush CQE process is triggered, the subsequent QP destruction mbox can still be successfully posted but will be blocked in HW until the flush CQE process finishes. This causes further mbox posting timeouts in driver. The blocking time is related to QP depth. Considering an extreme case where SQ depth and RQ depth are both 32K, the blocking time can reach about 135ms. This patch adds a retry mechanism for mbox posting. For each try, FW waits 15ms for HW to complete the previous mbox, otherwise return a timeout error code to driver. Counting other time consumption in FW, set 8 tries for mbox posting and a 5ms time gap before each retry to increase to a sufficient timeout limit.

From: Aleksandr Loktionov <aleksandr.loktionov(a)intel.com> stable inclusion from stable-v4.19.24 commit 15950157e2c24865b696db1c9ccc72743ae0e967 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP4HT CVE: CVE-2022-49725 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… ---------------------------------------------------------------------- [ Upstream commit fd5855e6b1358e816710afee68a1d2bc685176ca ] After PF reset and ethtool -t there was call trace in dmesg sometimes leading to panic. When there was some time, around 5 seconds, between reset and test there were no errors. Problem was that pf reset calls i40e_vsi_close in prep_for_reset and ethtool -t calls i40e_vsi_close in diag_test. If there was not enough time between those commands the second i40e_vsi_close starts before previous i40e_vsi_close was done which leads to crash. Add check to diag_test if pf is in reset and don't start offline tests if it is true. Add netif_info("testing failed") into unhappy path of i40e_diag_test() Fixes: e17bc411aea8 ("i40e: Disable offline diagnostics if VFs are enabled") Fixes: 510efb2682b3 ("i40e: Fix ethtool offline diagnostic with netqueues") Signed-off-by: Michal Jaron <michalx.jaron(a)intel.com> Signed-off-by: Aleksandr Loktionov <aleksandr.loktionov(a)intel.com> Tested-by: Gurucharan <gurucharanx.g(a)intel.com> (A Contingent worker at Intel) Signed-off-by: Tony Nguyen <anthony.l.nguyen(a)intel.com> Signed-off-by: Sasha Levin <sashal(a)kernel.org> Signed-off-by: Chen Ridong <chenridong(a)huawei.com> Reviewed-by: Xiu Jianfeng <xiujianfeng(a)huawei.com> --- .../net/ethernet/intel/i40e/i40e_ethtool.c | 25 +++++++++++++------ 1 file changed, 17 insertions(+), 8 deletions(-) diff --git a/drivers/net/ethernet/intel/i40e/i40e_ethtool.c b/drivers/net/ethernet/intel/i40e/i40e_ethtool.c index a6b0f605a7d8..50f56a51bbc7 100644 --- a/drivers/net/ethernet/intel/i40e/i40e_ethtool.c +++ b/drivers/net/ethernet/intel/i40e/i40e_ethtool.c @@ -2195,15 +2195,16 @@ static void i40e_diag_test(struct net_device *netdev, set_bit(__I40E_TESTING, pf->state); + if (test_bit(__I40E_RESET_RECOVERY_PENDING, pf->state) || + test_bit(__I40E_RESET_INTR_RECEIVED, pf->state)) { + dev_warn(&pf->pdev->dev, + "Cannot start offline testing when PF is in reset state.\n"); + goto skip_ol_tests; + } + if (i40e_active_vfs(pf) || i40e_active_vmdqs(pf)) { dev_warn(&pf->pdev->dev, "Please take active VFs and Netqueues offline and restart the adapter before running NIC diagnostics\n"); - data[I40E_ETH_TEST_REG] = 1; - data[I40E_ETH_TEST_EEPROM] = 1; - data[I40E_ETH_TEST_INTR] = 1; - data[I40E_ETH_TEST_LINK] = 1; - eth_test->flags |= ETH_TEST_FL_FAILED; - clear_bit(__I40E_TESTING, pf->state); goto skip_ol_tests; } @@ -2250,9 +2251,17 @@ static void i40e_diag_test(struct net_device *netdev, data[I40E_ETH_TEST_INTR] = 0; } -skip_ol_tests: - netif_info(pf, drv, netdev, "testing finished\n"); + return; + +skip_ol_tests: + data[I40E_ETH_TEST_REG] = 1; + data[I40E_ETH_TEST_EEPROM] = 1; + data[I40E_ETH_TEST_INTR] = 1; + data[I40E_ETH_TEST_LINK] = 1; + eth_test->flags |= ETH_TEST_FL_FAILED; + clear_bit(__I40E_TESTING, pf->state); + netif_info(pf, drv, netdev, "testing failed\n"); } static void i40e_get_wol(struct net_device *netdev, -- 2.34.1

[PATCH OLK-5.10] ubi: fastmap: wl: Schedule fm_work if wear-leveling pool is empty
by Wang Zhaolong 10 Mar '25

10 Mar '25

From: Zhihao Cheng <chengzhihao1(a)huawei.com> mainline inclusion from mainline-v6.13-rc1 commit c4595fe394a289927077e3da561db27811919ee0 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBS8G5 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Since commit 14072ee33d5a ("ubi: fastmap: Check wl_pool for free peb before wear leveling"), wear_leveling_worker() won't schedule fm_work if wear-leveling pool is empty, which could temporarily disable the wear-leveling until the fastmap is updated(eg. pool becomes empty). Fix it by scheduling fm_work if wl_pool is empty during wear-leveing.

From: Martin KaFai Lau <martin.lau(a)kernel.org> stable inclusion from stable-v6.6.76 commit 3392fa605d7c5708c5fbe02e4fbdac547c3b7352 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBREBI CVE: CVE-2024-58070 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 8eef6ac4d70eb1f0099fff93321d90ce8fa49ee1 ] In PREEMPT_RT, kmalloc(GFP_ATOMIC) is still not safe in non preemptible context. bpf_mem_alloc must be used in PREEMPT_RT. This patch is to enforce bpf_mem_alloc in the bpf_local_storage when CONFIG_PREEMPT_RT is enabled.

It has been an old issue since the first introduction of the bpf_local_storage ~5 years ago, so this patch targets the bpf-next. bpf_mem_alloc is needed to solve it, so the Fixes tag is set to the commit when bpf_mem_alloc was first used in the bpf_local_storage.

[PATCH OLK-5.10] ocfs2: handle a symlink read error correctly

From: "Matthew Wilcox (Oracle)" <willy(a)infradead.org> mainline inclusion from mainline-v6.14-rc1 commit 2b4c2094da6d84e69b843dd3317902e977bf64bd category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBPC8H CVE: CVE-2024-58001 Reference: https://git.kernel.org/stable/c/2b4c2094da6d84e69b843dd3317902e977bf64bd -------------------------------- Patch series "Convert ocfs2 to use folios". Mark did a conversion of ocfs2 to use folios and sent it to me as a giant patch for review ;-) So I've redone it as individual patches, and credited Mark for the patches where his code is substantially the same. It's not a bad way to do it; his patch had some bugs and my patches had some bugs. Hopefully all our bugs were different from each other. And hopefully Mark likes all the changes I made to his code! This patch (of 23): If we can't read the buffer, be sure to unlock the page before returning.

Mark did a conversion of ocfs2 to use folios and sent it to me as a giant patch for review ;-) So I've redone it as individual patches, and credited Mark for the patches where his code is substantially the same. It's not a bad way to do it; his patch had some bugs and my patches had some bugs. Hopefully all our bugs were different from each other. And hopefully Mark likes all the changes I made to his code!

[PATCH openEuler-1.0-LTS] tracing/histograms: Fix memory leak problem
by Li Huafei 10 Mar '25

10 Mar '25

From: Zheng Yejian <zhengyejian1(a)huawei.com> stable inclusion from stable-v4.19.253 commit eb622d5580b9e2ff694f62da6410618bd73853cb category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP6IV CVE: CVE-2022-49648 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 7edc3945bdce9c39198a10d6129377a5c53559c2 upstream. This reverts commit 46bbe5c671e06f070428b9be142cc4ee5cedebac. As commit 46bbe5c671e0 ("tracing: fix double free") said, the "double free" problem reported by clang static analyzer is: > In parse_var_defs() if there is a problem allocating > var_defs.expr, the earlier var_defs.name is freed. > This free is duplicated by free_var_defs() which frees > the rest of the list. However, if there is a problem allocating N-th var_defs.expr: + in parse_var_defs(), the freed 'earlier var_defs.name' is actually the N-th var_defs.name; + then in free_var_defs(), the names from 0th to (N-1)-th are freed; IF ALLOCATING PROBLEM HAPPENED HERE!!! -+ \ | 0th 1th (N-1)-th N-th V +-------------+-------------+-----+-------------+----------- var_defs: | name | expr | name | expr | ... | name | expr | name | /// +-------------+-------------+-----+-------------+----------- These two frees don't act on same name, so there was no "double free" problem before. Conversely, after that commit, we get a "memory leak" problem because the above "N-th var_defs.name" is not freed. If enable CONFIG_DEBUG_KMEMLEAK and inject a fault at where the N-th var_defs.expr allocated, then execute on shell like: $ echo 'hist:key=call_site:val=$v1,$v2:v1=bytes_req,v2=bytes_alloc' > \ /sys/kernel/debug/tracing/events/kmem/kmalloc/trigger Then kmemleak reports: unreferenced object 0xffff8fb100ef3518 (size 8): comm "bash", pid 196, jiffies 4295681690 (age 28.538s) hex dump (first 8 bytes): 76 31 00 00 b1 8f ff ff v1...... backtrace: [<0000000038fe4895>] kstrdup+0x2d/0x60 [<00000000c99c049a>] event_hist_trigger_parse+0x206f/0x20e0 [<00000000ae70d2cc>] trigger_process_regex+0xc0/0x110 [<0000000066737a4c>] event_trigger_write+0x75/0xd0 [<000000007341e40c>] vfs_write+0xbb/0x2a0 [<0000000087fde4c2>] ksys_write+0x59/0xd0 [<00000000581e9cdf>] do_syscall_64+0x3a/0x80 [<00000000cf3b065c>] entry_SYSCALL_64_after_hwframe+0x46/0xb0 Link: https://lkml.kernel.org/r/20220711014731.69520-1-zhengyejian1@huawei.com Cc: stable(a)vger.kernel.org Fixes: 46bbe5c671e0 ("tracing: fix double free") Reported-by: Hulk Robot <hulkci(a)huawei.com> Suggested-by: Steven Rostedt <rostedt(a)goodmis.org> Reviewed-by: Tom Zanussi <tom.zanussi(a)linux.intel.com> Signed-off-by: Zheng Yejian <zhengyejian1(a)huawei.com> Signed-off-by: Steven Rostedt (Google) <rostedt(a)goodmis.org> Signed-off-by: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> Signed-off-by: Li Huafei <lihuafei1(a)huawei.com> --- kernel/trace/trace_events_hist.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/kernel/trace/trace_events_hist.c b/kernel/trace/trace_events_hist.c index 638566ea7839..2f57eb241ac9 100644 --- a/kernel/trace/trace_events_hist.c +++ b/kernel/trace/trace_events_hist.c @@ -4155,6 +4155,8 @@ static int parse_var_defs(struct hist_trigger_data *hist_data) s = kstrdup(field_str, GFP_KERNEL); if (!s) { + kfree(hist_data->attrs->var_defs.name[n_vars]); + hist_data->attrs->var_defs.name[n_vars] = NULL; ret = -ENOMEM; goto free; } -- 2.25.1

[PATCH openEuler-1.0-LTS v2 0/2] Ignore SB_RDONLY when mounting and remounting nfs
by Li Lingfeng 08 Mar '25

08 Mar '25

When NFS_MOUNT_UNSHARED is not set, NFS forces the sharing of a superblock among each filesystem that mounts sub-directories elonging to a single exported root path. To prevent interference between different filesystems, ignore SB_RDONLY when mounting and remounting nfs. Li Lingfeng (2): nfs: clear SB_RDONLY before getting superblock nfs: ignore SB_RDONLY when remounting nfs --- Changes in v2: - Change the bugzilla tag to the gitee link. --- fs/nfs/super.c | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) -- 2.31.1

[PATCH OLK-6.6] nilfs2: fix possible int overflows in nilfs_fiemap()

From: Nikita Zhandarovich <n.zhandarovich(a)fintech.ru> stable inclusion from stable-v6.6.78 commit f2bd0f1ab47822fe5bd699c8458b896c4b2edea1 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBPC8Z CVE: CVE-2025-21736 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- commit 6438ef381c183444f7f9d1de18f22661cba1e946 upstream. Since nilfs_bmap_lookup_contig() in nilfs_fiemap() calculates its result by being prepared to go through potentially maxblocks == INT_MAX blocks, the value in n may experience an overflow caused by left shift of blkbits. While it is extremely unlikely to occur, play it safe and cast right hand expression to wider type to mitigate the issue.

[PATCH openEuler-1.0-LTS] hfsplus: don't query the device logical block size multiple times
by Chen Zhongjin 07 Mar '25

07 Mar '25

From: Thadeu Lima de Souza Cascardo <cascardo(a)igalia.com> stable inclusion from stable-v4.19.325 commit baccb5e12577b7a9eff54ffba301fdaa0f3ee5a8 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBEADN CVE: CVE-2024-56548 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- [ Upstream commit 1c82587cb57687de3f18ab4b98a8850c789bedcf ] Devices block sizes may change. One of these cases is a loop device by using ioctl LOOP_SET_BLOCK_SIZE. While this may cause other issues like IO being rejected, in the case of hfsplus, it will allocate a block by using that size and potentially write out-of-bounds when hfsplus_read_wrapper calls hfsplus_submit_bio and the latter function reads a different io_size. Using a new min_io_size initally set to sb_min_blocksize works for the purposes of the original fix, since it will be set to the max between HFSPLUS_SECTOR_SIZE and the first seen logical block size. We still use the max between HFSPLUS_SECTOR_SIZE and min_io_size in case the latter is not initialized. Tested by mounting an hfsplus filesystem with loop block sizes 512, 1024 and 4096.

From: Thadeu Lima de Souza Cascardo <cascardo(a)igalia.com> stable inclusion from stable-v4.19.325 commit baccb5e12577b7a9eff54ffba301fdaa0f3ee5a8 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBEADN CVE: CVE-2024-56548 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… 66090815a24ce14cf51ef5453fc0218fe8a39bc2 -------------------------------- [ Upstream commit 1c82587cb57687de3f18ab4b98a8850c789bedcf ] Devices block sizes may change. One of these cases is a loop device by using ioctl LOOP_SET_BLOCK_SIZE. While this may cause other issues like IO being rejected, in the case of hfsplus, it will allocate a block by using that size and potentially write out-of-bounds when hfsplus_read_wrapper calls hfsplus_submit_bio and the latter function reads a different io_size. Using a new min_io_size initally set to sb_min_blocksize works for the purposes of the original fix, since it will be set to the max between HFSPLUS_SECTOR_SIZE and the first seen logical block size. We still use the max between HFSPLUS_SECTOR_SIZE and min_io_size in case the latter is not initialized. Tested by mounting an hfsplus filesystem with loop block sizes 512, 1024 and 4096.

If the locking correctness validator is on then an INFO message and stack trace resembling the following may be seen: INFO: trying to register non-static key.

[PATCH OLK-5.10] Bluetooth: L2CAP: handle NULL sock pointer in l2cap_sock_alloc
by Yang Yingliang 07 Mar '25

07 Mar '25

From: Fedor Pchelkin <pchelkin(a)ispras.ru> mainline inclusion from mainline-v6.14-rc1 commit 5f397409f8ee5bc82901eeaf799e1cbc4f8edcf1 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBPC5E CVE: CVE-2024-58009 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- A NULL sock pointer is passed into l2cap_sock_alloc() when it is called from l2cap_sock_new_connection_cb() and the error handling paths should also be aware of it. Seemingly a more elegant solution would be to swap bt_sock_alloc() and l2cap_chan_create() calls since they are not interdependent to that moment but then l2cap_chan_create() adds the soon to be deallocated and still dummy-initialized channel to the global list accessible by many L2CAP paths. The channel would be removed from the list in short period of time but be a bit more straight-forward here and just check for NULL instead of changing the order of function calls. Found by Linux Verification Center (linuxtesting.org) with SVACE static analysis tool.

[PATCH OLK-5.10] bus: fsl-mc-bus: fix KASAN use-after-free in fsl_mc_bus_remove()
by Tirui Yin 06 Mar '25

From: Shin'ichiro Kawasaki <shinichiro.kawasaki(a)wdc.com> mainline inclusion from mainline-v5.19-rc3 commit 928ea98252ad75118950941683893cf904541da9 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP74W CVE: CVE-2022-49711 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- In fsl_mc_bus_remove(), mc->root_mc_bus_dev->mc_io is passed to fsl_destroy_mc_io(). However, mc->root_mc_bus_dev is already freed in fsl_mc_device_remove(). Then reference to mc->root_mc_bus_dev->mc_io triggers KASAN use-after-free. To avoid the use-after-free, keep the reference to mc->root_mc_bus_dev->mc_io in a local variable and pass to fsl_destroy_mc_io(). This patch needs rework to apply to kernels older than v5.15.

mainline inclusion from mainline-v5.18-rc1 commit b0bfaf0544d08d093d6211d7ef8816fb0b5b6c75 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP3KX CVE: CVE-2022-49246 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- The device_node pointer is returned by of_parse_phandle() with refcount incremented. We should use of_node_put() on it when done. This function only calls of_node_put() in the regular path. And it will cause refcount leak in error paths. Fix this by calling of_node_put() in error handling too.

[PATCH openEuler-1.0-LTS] can: gs_usb: gs_usb_open/close(): fix memory leak
by Jinjie Ruan 06 Mar '25

06 Mar '25

From: Rhett Aultman <rhett.aultman(a)samsara.com> stable inclusion from stable-v4.19.252 commit d91492638b054f4a359621ef216242be5973ed6b category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP6SC CVE: CVE-2022-49661 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 2bda24ef95c0311ab93bda00db40486acf30bd0a upstream. The gs_usb driver appears to suffer from a malady common to many USB CAN adapter drivers in that it performs usb_alloc_coherent() to allocate a number of USB request blocks (URBs) for RX, and then later relies on usb_kill_anchored_urbs() to free them, but this doesn't actually free them. As a result, this may be leaking DMA memory that's been used by the driver. This commit is an adaptation of the techniques found in the esd_usb2 driver where a similar design pattern led to a memory leak. It explicitly frees the RX URBs and their DMA memory via a call to usb_free_coherent(). Since the RX URBs were allocated in the gs_can_open(), we remove them in gs_can_close() rather than in the disconnect function as was done in esd_usb2. For more information, see the 928150fad41b ("can: esd_usb2: fix memory leak").

[PATCH OLK-6.6] libbpf: Fix segfault due to libelf functions not setting errno
by Xiaomeng Zhang 06 Mar '25

06 Mar '25

From: Quentin Monnet <qmo(a)kernel.org> mainline inclusion from mainline-v6.14-rc1 commit e10500b69c3f3378f3dcfc8c2fe4cdb74fc844f5 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBR43L Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Libelf functions do not set errno on failure. Instead, it relies on its internal _elf_errno value, that can be retrieved via elf_errno (or the corresponding message via elf_errmsg()). From "man libelf": If a libelf function encounters an error it will set an internal error code that can be retrieved with elf_errno. Each thread maintains its own separate error code. The meaning of each error code can be determined with elf_errmsg, which returns a string describing the error. As a consequence, libbpf should not return -errno when a function from libelf fails, because an empty value will not be interpreted as an error and won't prevent the program to stop. This is visible in bpf_linker__add_file(), for example, where we call a succession of functions that rely on libelf: err = err ?: linker_load_obj_file(linker, filename, opts, &obj); err = err ?: linker_append_sec_data(linker, &obj); err = err ?: linker_append_elf_syms(linker, &obj); err = err ?: linker_append_elf_relos(linker, &obj); err = err ?: linker_append_btf(linker, &obj); err = err ?: linker_append_btf_ext(linker, &obj); If the object file that we try to process is not, in fact, a correct object file, linker_load_obj_file() may fail with errno not being set, and return 0. In this case we attempt to run linker_append_elf_sysms() and may segfault. This can happen (and was discovered) with bpftool: $ bpftool gen object output.o sample_ret0.bpf.c libbpf: failed to get ELF header for sample_ret0.bpf.c: invalid `Elf' handle zsh: segmentation fault (core dumped) bpftool gen object output.o sample_ret0.bpf.c Fix the issue by returning a non-null error code (-EINVAL) when libelf functions fail.

This is cluster-md speical bug. In non-clustered env, mdadm will handle broken metadata case. In clustered array, only kernel space handles bitmap slot info. But even this bug only happened in clustered env, current sanity check is wrong, the code should be changed. How to trigger: (faulty injection) dd if=/dev/zero bs=1M count=1 oflag=direct of=/dev/sda dd if=/dev/zero bs=1M count=1 oflag=direct of=/dev/sdb mdadm -C /dev/md0 -b clustered -e 1.2 -n 2 -l mirror /dev/sda /dev/sdb mdadm -Ss echo aaa > magic.txt == below modifying slot 2 bitmap data == dd if=magic.txt of=/dev/sda seek=16384 bs=1 count=3 <== destroy magic dd if=/dev/zero of=/dev/sda seek=16436 bs=1 count=4 <== ZERO chunksize mdadm -A /dev/md0 /dev/sda /dev/sdb == kernel crashes. mdadm outputs "Segmentation fault" == Reason of kernel crash: In md_bitmap_read_sb (called by md_bitmap_create), bad bitmap magic didn't block chunksize assignment, and zero value made DIV_ROUND_UP_SECTOR_T() trigger "divide error".

From: Niklas Cassel <cassel(a)kernel.org> stable inclusion from stable-v6.6.78 commit d5e6e3000309359eae2a17117aa6e3c44897bf6c category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ CVE: CVE-2025-21738 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… ------------------ commit 6e74e53b34b6dec5a50e1404e2680852ec6768d2 upstream. reveliofuzzing reported that a SCSI_IOCTL_SEND_COMMAND ioctl with out_len set to 0xd42, SCSI command set to ATA_16 PASS-THROUGH, ATA command set to ATA_NOP, and protocol set to ATA_PROT_PIO, can cause ata_pio_sector() to write outside the allocated buffer, overwriting random memory. While a ATA device is supposed to abort a ATA_NOP command, there does seem to be a bug either in libata-sff or QEMU, where either this status is not set, or the status is cleared before read by ata_sff_hsm_move(). Anyway, that is most likely a separate bug. Looking at __atapi_pio_bytes(), it already has a safety check to ensure that __atapi_pio_bytes() cannot write outside the allocated buffer. Add a similar check to ata_pio_sector(), such that also ata_pio_sector() cannot write outside the allocated buffer.

[PATCH openEuler-1.0-LTS] rtl818x: Prevent using not initialized queues
by Luo Gengkun 06 Mar '25

06 Mar '25

From: Alexander Wetzel <alexander(a)wetzel-home.de> stable inclusion from stable-v4.19.247 commit 9d5e96cc1f1720019ce27b127a31695148d38bb0 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP1BA CVE: CVE-2022-49326 Reference: https://git.kernel.org/stable/c/9d5e96cc1f1720019ce27b127a31695148d38bb0 -------------------------------- commit 746285cf81dc19502ab238249d75f5990bd2d231 upstream. Using not existing queues can panic the kernel with rtl8180/rtl8185 cards. Ignore the skb priority for those cards, they only have one tx queue. Pierre Asselin (pa(a)panix.com) reported the kernel crash in the Gentoo forum: https://forums.gentoo.org/viewtopic-t-1147832-postdays-0-postorder-asc-star… He also confirmed that this patch fixes the issue. In summary this happened: After updating wpa_supplicant from 2.9 to 2.10 the kernel crashed with a "divide error: 0000" when connecting to an AP. Control port tx now tries to use IEEE80211_AC_VO for the priority, which wpa_supplicants starts to use in 2.10. Since only the rtl8187se part of the driver supports QoS, the priority of the skb is set to IEEE80211_AC_BE (2) by mac80211 for rtl8180/rtl8185 cards. rtl8180 is then unconditionally reading out the priority and finally crashes on drivers/net/wireless/realtek/rtl818x/rtl8180/dev.c line 544 without this patch: idx = (ring->idx + skb_queue_len(&ring->queue)) % ring->entries "ring->entries" is zero for rtl8180/rtl8185 cards, tx_ring[2] never got initialized.

[PATCH OLK-6.6] USB: hub: Ignore non-compliant devices with too many configs or interfaces
by Bowen You 06 Mar '25

From: Alan Stern <stern(a)rowland.harvard.edu> mainline inclusion from mainline-v6.12-rc1 commit 2240fed37afbcdb5e8b627bc7ad986891100e05d category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBPC7J CVE: CVE-2025-21776 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Robert Morris created a test program which can cause usb_hub_to_struct_hub() to dereference a NULL or inappropriate pointer: Oops: general protection fault, probably for non-canonical address 0xcccccccccccccccc: 0000 [#1] SMP DEBUG_PAGEALLOC PTI CPU: 7 UID: 0 PID: 117 Comm: kworker/7:1 Not tainted 6.13.0-rc3-00017-gf44d154d6e3d #14 Hardware name: FreeBSD BHYVE/BHYVE, BIOS 14.0 10/17/2021 Workqueue: usb_hub_wq hub_event RIP: 0010:usb_hub_adjust_deviceremovable+0x78/0x110 ...

We can prevent the problem from occurring by refusing to accept hub devices that violate the USB spec by having more than one configuration or interface.

[PATCH openEuler-1.0-LTS] ALSA: usb-audio: Cancel pending work at closing a MIDI substream
by Zhang Kunbo 06 Mar '25

06 Mar '25

From: Takashi Iwai <tiwai(a)suse.de> stable inclusion from stable-v5.10.121 commit 40bdb5ec957aca5c5c1924602bef6b0ab18e22d3 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP6ZR CVE: CVE-2022-49545 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 0125de38122f0f66bf61336158d12a1aabfe6425 upstream. At closing a USB MIDI output substream, there might be still a pending work, which would eventually access the rawmidi runtime object that is being released. For fixing the race, make sure to cancel the pending work at closing.

[PATCH openEuler-22.03-LTS-SP1 00/23] Support perf --bpf-counters
by Tengda Wu 05 Mar '25

05 Mar '25

This is a minimal patch series to enable '--bpf-counters' options for perf tool in 5.10 kernel version. How to compile? =============== 1. Download openEuler kernel source code: git clone https://gitee.com/openeuler/kernel.git 2. Download these patches, apply them in kernel/ directory: cd kernel/ git am --reject /path/to/*.patch 3. Prepare some requirements before compiling perf tool: Not list one by one here, please refer to [1]. [1] https://medium.com/@manas.marwah/building-perf-tool-fc838f084f71 4. Compile perf tool: cd tools/perf make BUILD_BPF_SKEL=1 If successful, you will see a binary file named 'perf' under tools/perf/ directory. How to use? =========== 1. Use bperf to sample a process: $ perf stat --bpf-counters -e cycles,instructions \ perf bench sched messaging -g 1 -l 100 -t # Running 'sched/messaging' benchmark: # 20 sender and receiver threads per group # 1 groups == 40 threads run Total time: 0.011 [sec] Performance counter stats for 'perf bench sched messaging -g 1 -l 100 -t': 639,816,606 cycles 284,102,919 instructions # 0.44 insn per cycle 0.018093452 seconds time elapsed 0.023612000 seconds user 0.255643000 seconds sys 2. Use bperf to sample a container: $ perf stat --bpf-counters -e cycles,instructions --timeout 1000 \ --for-each-cgroup docker/66166578dd7d17655923862792a0b9d60c8785fdc1bb8da8b76daedb205c4b10 Performance counter stats for 'system wide': 7,402,983 cycles docker/66166578dd7d17655923862792a0b9d60c8785fdc1bb8da8b76daedb205c4b10 6,036,926 instructions docker/66166578dd7d17655923862792a0b9d60c8785fdc1bb8da8b76daedb205c4b10 # 0.82 insn per cycle 1.004999462 seconds time elapsed How to integrate via bpf? ======================== If you are interested in process sampling, please check the following bpf progs: tools/perf/util/bpf_skel/bperf_leader.bpf.c tools/perf/util/bpf_skel/bperf_follower.bpf.c And if you are interested in container sampling, please check the following bpf prog: tools/perf/util/bpf_skel/bperf_cgroup.bpf.c There have some documents in tools/perf/util/bpf_counter.c, search the keywords 'bperf: share hardware PMCs with BPF' in it and see how bperf works. That's all. Enjoy. Namhyung Kim (9): bpf: Allow bpf_get_current_ancestor_cgroup_id for tracing perf core: Factor out __perf_sw_event_sched perf core: Add PERF_COUNT_SW_CGROUP_SWITCHES event perf tools: Add 'cgroup-switches' software event perf tools: Add read_cgroup_id() function perf tools: Add cgroup_is_v2() helper perf bpf_counter: Move common functions to bpf_counter.h perf stat: Enable BPF counter with --for-each-cgroup perf stat: Fix BPF program section name Song Liu (12): bpftool: Add Makefile target bootstrap perf build: Support build BPF skeletons with perf perf stat: Enable counting events for BPF programs perf stat: Introduce 'bperf' to share hardware PMCs with BPF perf stat: Measure 't0' and 'ref_time' after enable_counters() perf util: Move bpf_perf definitions to a libperf header perf bpf: check perf_attr_map is compatible with the perf binary perf stat: Introduce config stat.bpf-counter-events perf stat: Introduce ':b' modifier perf stat: Introduce bpf_counter_ops->disable() perf bpf: Fix building perf with BUILD_BPF_SKEL=1 by default in more distros perf bpf_skel: Do not use typedef to avoid error on old clang Tengda Wu (1): perf stat: Support inherit events during fork() for bperf Xiaomeng Zhang (1): perf stat: Increase perf_attr_map entries include/linux/perf_event.h | 40 +- include/uapi/linux/perf_event.h | 1 + kernel/trace/bpf_trace.c | 2 + tools/bpf/bpftool/Makefile | 2 + tools/build/Makefile.feature | 4 +- tools/include/uapi/linux/perf_event.h | 7 + tools/lib/perf/include/perf/bpf_perf.h | 31 + tools/perf/Documentation/perf-stat.txt | 31 + tools/perf/Makefile.config | 9 + tools/perf/Makefile.perf | 65 +- tools/perf/builtin-stat.c | 111 ++- tools/perf/util/Build | 2 + tools/perf/util/bpf_counter.c | 828 ++++++++++++++++++ tools/perf/util/bpf_counter.h | 131 +++ tools/perf/util/bpf_counter_cgroup.c | 307 +++++++ tools/perf/util/bpf_skel/.gitignore | 3 + tools/perf/util/bpf_skel/bperf_cgroup.bpf.c | 191 ++++ tools/perf/util/bpf_skel/bperf_follower.bpf.c | 162 ++++ tools/perf/util/bpf_skel/bperf_leader.bpf.c | 55 ++ tools/perf/util/bpf_skel/bperf_u.h | 19 + .../util/bpf_skel/bpf_prog_profiler.bpf.c | 93 ++ tools/perf/util/cgroup.c | 47 + tools/perf/util/cgroup.h | 13 + tools/perf/util/config.c | 4 + tools/perf/util/evlist.c | 4 + tools/perf/util/evsel.c | 27 + tools/perf/util/evsel.h | 32 + tools/perf/util/parse-events.c | 12 +- tools/perf/util/parse-events.l | 3 +- tools/perf/util/python.c | 27 + tools/perf/util/stat-display.c | 4 +- tools/perf/util/stat.c | 2 +- tools/perf/util/target.c | 34 +- tools/perf/util/target.h | 8 + tools/scripts/Makefile.include | 1 + 35 files changed, 2266 insertions(+), 46 deletions(-) create mode 100644 tools/lib/perf/include/perf/bpf_perf.h create mode 100644 tools/perf/util/bpf_counter.c create mode 100644 tools/perf/util/bpf_counter.h create mode 100644 tools/perf/util/bpf_counter_cgroup.c create mode 100644 tools/perf/util/bpf_skel/.gitignore create mode 100644 tools/perf/util/bpf_skel/bperf_cgroup.bpf.c create mode 100644 tools/perf/util/bpf_skel/bperf_follower.bpf.c create mode 100644 tools/perf/util/bpf_skel/bperf_leader.bpf.c create mode 100644 tools/perf/util/bpf_skel/bperf_u.h create mode 100644 tools/perf/util/bpf_skel/bpf_prog_profiler.bpf.c -- 2.34.1

[PATCH OLK-6.6] btrfs: fix use-after-free when attempting to join an aborted transaction
by Long Li 05 Mar '25

05 Mar '25

From: Filipe Manana <fdmanana(a)suse.com> mainline inclusion from mainline-v6.10-rc2 commit e2f0943cf37305dbdeaf9846e3c941451bcdef63 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBPCA5 CVE: CVE-2025-21753 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- When we are trying to join the current transaction and if it's aborted, we read its 'aborted' field after unlocking fs_info->trans_lock and without holding any extra reference count on it. This means that a concurrent task that is aborting the transaction may free the transaction before we read its 'aborted' field, leading to a use-after-free. Fix this by reading the 'aborted' field while holding fs_info->trans_lock since any freeing task must first acquire that lock and set fs_info->running_transaction to NULL before freeing the transaction. This was reported by syzbot and Dmitry with the following stack traces from KASAN: ================================================================== BUG: KASAN: slab-use-after-free in

From: Jann Horn <jannh(a)google.com> mainline inclusion from mainline-v6.10-rc2 commit 80e648042e512d5a767da251d44132553fe04ae0 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBPC5K CVE: CVE-2025-21772 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Fix several issues in partition probing: - The bailout for a bad partoffset must use put_dev_sector(), since the preceding read_part_sector() succeeded. - If the partition table claims a silly sector size like 0xfff bytes (which results in partition table entries straddling sector boundaries), bail out instead of accessing out-of-bounds memory. - We must not assume that the partition table contains proper NUL termination - use strnlen() and strncmp() instead of strlen() and strcmp().

[PATCH OLK-6.6] perf/core: Save raw sample data conditionally based on sample type

From: Yabin Cui <yabinc(a)google.com> stable inclusion from stable-v6.6.76 commit c0dbecb204cfb91999d0b785048be4a95bbc8c9c category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBQXZY Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit b9c44b91476b67327a521568a854babecc4070ab ] Currently, space for raw sample data is always allocated within sample records for both BPF output and tracepoint events. This leads to unused space in sample records when raw sample data is not requested. This patch enforces checking sample type of an event in perf_sample_save_raw_data(). So raw sample data will only be saved if explicitly requested, reducing overhead when it is not needed.

[PATCH openEuler-25.03 v6 0/4] Add TrIO support in EROFS
by Hongbo Li 05 Mar '25

05 Mar '25

TrIO can accelerate the cold start of containers during on-demand loading. It aggregates the read I/O operations required for container runtime during the first container launch. In the following startups, TrIO pulls the necessary I/O data to the container node in a single large I/O operation and uses this I/O information to construct the runtime rootfs. By improving the efficiency of network I/O, TrIO speeds up container startup in on-demand loading scenarios. TrIO consists of both kernel-space and user-space code. The kernel-space code has been adapted at the overlayfs layer, introducing the CONFIG_EROFS_TRIO configuration to provide isolation. The user-space code requires adaptation by the user, and detailed usage methods are introduced in the tools/trio/README.md section. Patches 1~2 correspond to the kernel adaptations, while patches 3~4 are the scripts and best practices that TrIO relies on for its operation. v6: - Add folio_put after filemap_get_folio. - Filter trace with lowerdir v5: - Adapt to the large folio tracepoint in erofs. - Adapt to the multiple type of page size (4k and 64k). v4: - Avoid the memleak of meta_buf. - Fix some exception handle from reviewer's suggestions. - Use spinlock in kprobe context. v3: - Obtain and keep the trio_object in open. - Only close readahead in trio case.

From: Marc Kleine-Budde <mkl(a)pengutronix.de> stable inclusion from stable-v4.19.253 commit 7728d937ec403a1ceff9483023252d2cb8777f81 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP6AL CVE: CVE-2022-49275 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 2e8e79c416aae1de224c0f1860f2e3350fa171f8 upstream. can_put_echo_skb() will clone skb then free the skb. Move the can_put_echo_skb() for the m_can version 3.0.x directly before the start of the xmit in hardware, similar to the 3.1.x branch.

[PATCH OLK-6.6] printk: Fix signed integer overflow when defining LOG_BUF_LEN_MAX
by Xiaomeng Zhang 05 Mar '25

05 Mar '25

From: Kuan-Wei Chiu <visitorckw(a)gmail.com> mainline inclusion from mainline-v6.14-rc1 commit 3d6f83df8ff2d5de84b50377e4f0d45e25311c7a category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBQPCU Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Shifting 1 << 31 on a 32-bit int causes signed integer overflow, which leads to undefined behavior. To prevent this, cast 1 to u32 before performing the shift, ensuring well-defined behavior.

[PATCH openEuler-25.03 v6 0/4] Add TrIO support in EROFS
by Hongbo Li 05 Mar '25

05 Mar '25

TrIO can accelerate the cold start of containers during on-demand loading. It aggregates the read I/O operations required for container runtime during the first container launch. In the following startups, TrIO pulls the necessary I/O data to the container node in a single large I/O operation and uses this I/O information to construct the runtime rootfs. By improving the efficiency of network I/O, TrIO speeds up container startup in on-demand loading scenarios. TrIO consists of both kernel-space and user-space code. The kernel-space code has been adapted at the overlayfs layer, introducing the CONFIG_EROFS_TRIO configuration to provide isolation. The user-space code requires adaptation by the user, and detailed usage methods are introduced in the tools/trio/README.md section. Patches 1~2 correspond to the kernel adaptations, while patches 3~4 are the scripts and best practices that TrIO relies on for its operation. v6: - Add folio_put after filemap_get_folio. v5: - Adapt to the large folio tracepoint in erofs. - Adapt to the multiple type of page size (4k and 64k). v4: - Avoid the memleak of meta_buf. - Fix some exception handle from reviewer's suggestions. - Use spinlock in kprobe context. v3: - Obtain and keep the trio_object in open. - Only close readahead in trio case.

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBKHTZ ------------------------ When writing to a RAID1 array where all member disks have bad sectors at the target location, the bitmap update is skipped because all bios[] are NULL, leading to bitmap counter inconsistency. This can cause subsequent I/O operations to hang while waiting for bitmap counter to reach the expected value. Fix this by updating the bitmap when all member disks have bad sectors.

[PATCH openEuler-1.0-LTS] ocfs2: dlmfs: fix error handling of user_dlm_destroy_lock
by Xiangwei Li 04 Mar '25

04 Mar '25

From: Junxiao Bi via Ocfs2-devel <ocfs2-devel(a)oss.oracle.com> stable inclusion from stable-v4.19.247 commit 733a35c00ef363a1c774d7ea486e0735b7c13a15 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP72J CVE: CVE-2022-49337 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 863e0d81b6683c4cbc588ad831f560c90e494bef upstream. When user_dlm_destroy_lock failed, it didn't clean up the flags it set before exit. For USER_LOCK_IN_TEARDOWN, if this function fails because of lock is still in used, next time when unlink invokes this function, it will return succeed, and then unlink will remove inode and dentry if lock is not in used(file closed), but the dlm lock is still linked in dlm lock resource, then when bast come in, it will trigger a panic due to user-after-free. See the following panic call trace. To fix this, USER_LOCK_IN_TEARDOWN should be reverted if fail. And also error should be returned if USER_LOCK_IN_TEARDOWN is set to let user know that unlink fail. For the case of ocfs2_dlm_unlock failure, besides USER_LOCK_IN_TEARDOWN, USER_LOCK_BUSY is also required to be cleared. Even though spin lock is released in between, but USER_LOCK_IN_TEARDOWN is still set, for USER_LOCK_BUSY, if before every place that waits on this flag, USER_LOCK_IN_TEARDOWN is checked to bail out, that will make sure no flow waits on the busy flag set by user_dlm_destroy_lock(), then we can simplely revert USER_LOCK_BUSY when ocfs2_dlm_unlock fails. Fix user_dlm_cluster_lock() which is the only function not following this.

[PATCH openEuler-25.03 v5 0/4] Add TrIO support in EROFS
by Hongbo Li 04 Mar '25

04 Mar '25

TrIO can accelerate the cold start of containers during on-demand loading. It aggregates the read I/O operations required for container runtime during the first container launch. In the following startups, TrIO pulls the necessary I/O data to the container node in a single large I/O operation and uses this I/O information to construct the runtime rootfs. By improving the efficiency of network I/O, TrIO speeds up container startup in on-demand loading scenarios. TrIO consists of both kernel-space and user-space code. The kernel-space code has been adapted at the overlayfs layer, introducing the CONFIG_EROFS_TRIO configuration to provide isolation. The user-space code requires adaptation by the user, and detailed usage methods are introduced in the tools/trio/README.md section. Patches 1~2 correspond to the kernel adaptations, while patches 3~4 are the scripts and best practices that TrIO relies on for its operation. v5: - Adapt to the large folio tracepoint in erofs. - Adapt to the multiple type of page size (4k and 64k). v4: - Avoid the memleak of meta_buf. - Fix some exception handle from reviewer's suggestions. - Use spinlock in kprobe context. v3: - Obtain and keep the trio_object in open. - Only close readahead in trio case.

[PATCH openEuler-1.0-LTS] md/raid1: fix bitmap update when all write requests fail
by Zheng Qixing 04 Mar '25

04 Mar '25

Offering: HULK hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBKHTZ CVE: NA ------------------------ When writing to a RAID1 array where all member disks have bad sectors at the target location, the bitmap update is skipped because all bios[] are NULL, leading to bitmap counter inconsistency. This can cause subsequent I/O operations to hang while waiting for bitmap counter to reach the expected value. Fix this by updating the bitmap when all member disks have bad sectors.

[PATCH OLK-6.6] usb: xhci: Fix NULL pointer dereference on certain command aborts

From: Michal Pecio <michal.pecio(a)gmail.com> stable inclusion from stable-v6.6.76 commit b649f0d5bc256f691c7d234c3986685d54053de1 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBPBJC CVE: CVE-2024-57981 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 1e0a19912adb68a4b2b74fd77001c96cd83eb073 upstream. If a command is queued to the final usable TRB of a ring segment, the enqueue pointer is advanced to the subsequent link TRB and no further. If the command is later aborted, when the abort completion is handled the dequeue pointer is advanced to the first TRB of the next segment. If no further commands are queued, xhci_handle_stopped_cmd_ring() sees the ring pointers unequal and assumes that there is a pending command, so it calls xhci_mod_cmd_timer() which crashes if cur_cmd was NULL. Don't attempt timer setup if cur_cmd is NULL. The subsequent doorbell ring likely is unnecessary too, but it's harmless. Leave it alone. This is probably Bug 219532, but no confirmation has been received. The issue has been independently reproduced and confirmed fixed using a USB MCU programmed to NAK the Status stage of SET_ADDRESS forever. Everything continued working normally after several prevented crashes.
