[PATCH OLK-5.10] crypto: pcrypt - Call crypto layer directly when padata_do_parallel() return -EBUSY
by Yi Yang 26 Nov '24

mainline inclusion from mainline-v6.13-rc1 commit 662f2f13e66d3883b9238b0b96b17886179e60e2 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I7RZMT Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Since commit 8f4f68e788c3 ("crypto: pcrypt - Fix hungtask for PADATA_RESET"), the pcrypt encryption and decryption operations return -EAGAIN when the CPU goes online or offline. In alg_test(), a WARN is generated when pcrypt_aead_decrypt() or pcrypt_aead_encrypt() returns -EAGAIN, the unnecessary panic will occur when panic_on_warn set 1.

[PATCH openEuler-22.03-LTS-SP1] afs: Fix lock recursion
by Yifan Qiao 26 Nov '24

26 Nov '24

From: David Howells <dhowells(a)redhat.com> mainline inclusion from mainline-v6.12-rc5 commit 610a79ffea02102899a1373fe226d949944a7ed6 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IB67YK CVE: CVE-2024-53090 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- afs_wake_up_async_call() can incur lock recursion. The problem is that it is called from AF_RXRPC whilst holding the ->notify_lock, but it tries to take a ref on the afs_call struct in order to pass it to a work queue - but if the afs_call is already queued, we then have an extraneous ref that must be put... calling afs_put_call() may call back down into AF_RXRPC through rxrpc_kernel_shutdown_call(), however, which might try taking the ->notify_lock again. This case isn't very common, however, so defer it to a workqueue.

[PATCH OLK-6.6] crypto: pcrypt - Call crypto layer directly when padata_do_parallel() return -EBUSY
by Yi Yang 26 Nov '24

26 Nov '24

mainline inclusion from mainline-v6.13-rc1 commit 662f2f13e66d3883b9238b0b96b17886179e60e2 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I7RZMT Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Since commit 8f4f68e788c3 ("crypto: pcrypt - Fix hungtask for PADATA_RESET"), the pcrypt encryption and decryption operations return -EAGAIN when the CPU goes online or offline. In alg_test(), a WARN is generated when pcrypt_aead_decrypt() or pcrypt_aead_encrypt() returns -EAGAIN, the unnecessary panic will occur when panic_on_warn set 1. Fix this issue by calling crypto layer directly without parallelization in that case.

[PATCH OLK-6.6] LoongArch: KVM: Mark hrtimer to expire in hard interrupt context
by Luo Gengkun 26 Nov '24

26 Nov '24

From: Huacai Chen <chenhuacai(a)loongson.cn> mainline inclusion from mainline-v6.12-rc5 commit 73adbd92f3223dc0c3506822b71c6b259d5d537b category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB67YA CVE: CVE-2024-53089 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Like commit 2c0d278f3293f ("KVM: LAPIC: Mark hrtimer to expire in hard interrupt context") and commit 9090825fa9974 ("KVM: arm/arm64: Let the timer expire in hardirq context on RT"), On PREEMPT_RT enabled kernels unmarked hrtimers are moved into soft interrupt expiry mode by default. Then the timers are canceled from an preempt-notifier which is invoked with disabled preemption which is not allowed on PREEMPT_RT. The timer callback is short so in could be invoked in hard-IRQ context. So let the timer expire on hard-IRQ context even on -RT. This fix a "scheduling while atomic" bug for PREEMPT_RT enabled kernels: BUG: scheduling while atomic: qemu-system-loo/1011/0x00000002 Modules linked in: amdgpu rfkill nft_fib_inet nft_fib_ipv4 nft_fib_ipv6 nft_fib nft_reject_inet nf_reject_ipv4 nf_reject_ipv6 nft_reject nft_ct nft_chain_nat ns CPU: 1 UID: 0 PID: 1011 Comm: qemu-system-loo Tainted: G W 6.12.0-rc2+ #1774 Tainted: [W]=WARN Hardware name: Loongson Loongson-3A5000-7A1000-1w-CRB/Loongson-LS3A5000-7A1000-1w-CRB, BIOS vUDK2018-LoongArch-V2.0.0-prebeta9 10/21/2022 Stack : ffffffffffffffff 0000000000000000 9000000004e3ea38 9000000116744000 90000001167475a0 0000000000000000 90000001167475a8 9000000005644830 90000000058dc000 90000000058dbff8 9000000116747420 0000000000000001 0000000000000001 6a613fc938313980 000000000790c000 90000001001c1140 00000000000003fe 0000000000000001 000000000000000d 0000000000000003 0000000000000030 00000000000003f3 000000000790c000 9000000116747830 90000000057ef000 0000000000000000 9000000005644830 0000000000000004 0000000000000000 90000000057f4b58 0000000000000001 9000000116747868 900000000451b600 9000000005644830 9000000003a13998 0000000010000020 00000000000000b0 0000000000000004 0000000000000000 0000000000071c1d ...

From: Kuniyuki Iwashima <kuniyu(a)amazon.com> mainline inclusion from mainline-v6.12-rc4 commit e8c526f2bdf1845bedaf6a478816a3d06fa78b8f category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB2STS CVE: CVE-2024-50154 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… ------------------------------------------------- Martin KaFai Lau reported use-after-free [0] in reqsk_timer_handler(). """ We are seeing a use-after-free from a bpf prog attached to trace_tcp_retransmit_synack. The program passes the req->sk to the bpf_sk_storage_get_tracing kernel helper which does check for null before using it. """ The commit 83fccfc3940c ("inet: fix potential deadlock in reqsk_queue_unlink()") added timer_pending() in reqsk_queue_unlink() not to call del_timer_sync() from reqsk_timer_handler(), but it introduced a small race window. Before the timer is called, expire_timers() calls detach_timer(timer, true) to clear timer->entry.pprev and marks it as not pending. If reqsk_queue_unlink() checks timer_pending() just after expire_timers() calls detach_timer(), TCP will miss del_timer_sync(); the reqsk timer will continue running and send multiple SYN+ACKs until it expires. The reported UAF could happen if req->sk is close()d earlier than the timer expiration, which is 63s by default. The scenario would be 1. inet_csk_complete_hashdance() calls inet_csk_reqsk_queue_drop(), but del_timer_sync() is missed 2. reqsk timer is executed and scheduled again 3. req->sk is accept()ed and reqsk_put() decrements rsk_refcnt, but reqsk timer still has another one, and inet_csk_accept() does not clear req->sk for non-TFO sockets 4. sk is close()d 5. reqsk timer is executed again, and BPF touches req->sk Let's not use timer_pending() by passing the caller context to __inet_csk_reqsk_queue_drop(). Note that reqsk timer is pinned, so the issue does not happen in most use cases.

[PATCH openEuler-22.03-LTS-SP1] pinctrl: ocelot: fix system hang on level based interrupts

From: Sergey Matsievskiy <matsievskiysv(a)gmail.com> mainline inclusion from mainline-v6.12-rc4 commit 93b8ddc54507a227087c60a0013ed833b6ae7d3c category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB2YX2 CVE: CVE-2024-50196 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- The current implementation only calls chained_irq_enter() and chained_irq_exit() if it detects pending interrupts. ``` for (i = 0; i < info->stride; i++) { uregmap_read(info->map, id_reg + 4 * i, &reg); if (!reg) continue; chained_irq_enter(parent_chip, desc); ``` However, in case of GPIO pin configured in level mode and the parent controller configured in edge mode, GPIO interrupt might be lowered by the hardware. In the result, if the interrupt is short enough, the parent interrupt is still pending while the GPIO interrupt is cleared; chained_irq_enter() never gets called and the system hangs trying to service the parent interrupt. Moving chained_irq_enter() and chained_irq_exit() outside the for loop ensures that they are called even when GPIO interrupt is lowered by the hardware. The similar code with chained_irq_enter() / chained_irq_exit() functions wrapping interrupt checking loop may be found in many other drivers: ``` grep -r -A 10 chained_irq_enter drivers/pinctrl ``` Cc: stable(a)vger.kernel.org Signed-off-by: Sergey Matsievskiy <matsievskiysv(a)gmail.com> Reviewed-by: Alexandre Belloni <alexandre.belloni(a)bootlin.com> Link: https://lore.kernel.org/20241012105743.12450-2-matsievskiysv@gmail.com Signed-off-by: Linus Walleij <linus.walleij(a)linaro.org> Conflicts: drivers/pinctrl/pinctrl-ocelot.c [Fix context conflicts.] Signed-off-by: Zeng Heng <zengheng4(a)huawei.com> --- drivers/pinctrl/pinctrl-ocelot.c | 7 +++---- 1 file changed, 3 insertions(+), 4 deletions(-) diff --git a/drivers/pinctrl/pinctrl-ocelot.c b/drivers/pinctrl/pinctrl-ocelot.c index a4a1b00f7f0d..e8ee2ade5293 100644 --- a/drivers/pinctrl/pinctrl-ocelot.c +++ b/drivers/pinctrl/pinctrl-ocelot.c @@ -1097,22 +1097,21 @@ static void ocelot_irq_handler(struct irq_desc *desc) unsigned int reg = 0, irq, i; unsigned long irqs; + chained_irq_enter(parent_chip, desc); + for (i = 0; i < info->stride; i++) { regmap_read(info->map, id_reg + 4 * i, &reg); if (!reg) continue; - chained_irq_enter(parent_chip, desc); - irqs = reg; for_each_set_bit(irq, &irqs, min(32U, info->desc->npins - 32 * i)) generic_handle_irq(irq_linear_revmap(chip->irq.domain, irq + 32 * i)); - - chained_irq_exit(parent_chip, desc); } + chained_irq_exit(parent_chip, desc); } static int ocelot_gpiochip_register(struct platform_device *pdev, -- 2.25.1

[PATCH OLK-5.10] pinctrl: ocelot: fix system hang on level based interrupts
by Zeng Heng 25 Nov '24

25 Nov '24

From: Sergey Matsievskiy <matsievskiysv(a)gmail.com> mainline inclusion from mainline-v6.12-rc4 commit 93b8ddc54507a227087c60a0013ed833b6ae7d3c category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB2YX2 CVE: CVE-2024-50196 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- The current implementation only calls chained_irq_enter() and chained_irq_exit() if it detects pending interrupts. ``` for (i = 0; i < info->stride; i++) { uregmap_read(info->map, id_reg + 4 * i, &reg); if (!reg) continue; chained_irq_enter(parent_chip, desc); ``` However, in case of GPIO pin configured in level mode and the parent controller configured in edge mode, GPIO interrupt might be lowered by the hardware. In the result, if the interrupt is short enough, the parent interrupt is still pending while the GPIO interrupt is cleared; chained_irq_enter() never gets called and the system hangs trying to service the parent interrupt. Moving chained_irq_enter() and chained_irq_exit() outside the for loop ensures that they are called even when GPIO interrupt is lowered by the hardware. The similar code with chained_irq_enter() / chained_irq_exit() functions wrapping interrupt checking loop may be found in many other drivers: ``` grep -r -A 10 chained_irq_enter drivers/pinctrl ``` Cc: stable(a)vger.kernel.org Signed-off-by: Sergey Matsievskiy <matsievskiysv(a)gmail.com> Reviewed-by: Alexandre Belloni <alexandre.belloni(a)bootlin.com> Link: https://lore.kernel.org/20241012105743.12450-2-matsievskiysv@gmail.com Signed-off-by: Linus Walleij <linus.walleij(a)linaro.org> Conflicts: drivers/pinctrl/pinctrl-ocelot.c [Fix context conflicts.] Signed-off-by: Zeng Heng <zengheng4(a)huawei.com> --- drivers/pinctrl/pinctrl-ocelot.c | 7 +++---- 1 file changed, 3 insertions(+), 4 deletions(-) diff --git a/drivers/pinctrl/pinctrl-ocelot.c b/drivers/pinctrl/pinctrl-ocelot.c index a4a1b00f7f0d..e8ee2ade5293 100644 --- a/drivers/pinctrl/pinctrl-ocelot.c +++ b/drivers/pinctrl/pinctrl-ocelot.c @@ -1097,22 +1097,21 @@ static void ocelot_irq_handler(struct irq_desc *desc) unsigned int reg = 0, irq, i; unsigned long irqs; + chained_irq_enter(parent_chip, desc); + for (i = 0; i < info->stride; i++) { regmap_read(info->map, id_reg + 4 * i, &reg); if (!reg) continue; - chained_irq_enter(parent_chip, desc); - irqs = reg; for_each_set_bit(irq, &irqs, min(32U, info->desc->npins - 32 * i)) generic_handle_irq(irq_linear_revmap(chip->irq.domain, irq + 32 * i)); - - chained_irq_exit(parent_chip, desc); } + chained_irq_exit(parent_chip, desc); } static int ocelot_gpiochip_register(struct platform_device *pdev, -- 2.25.1

[PATCH openEuler-1.0-LTS] vfs: fix race between evice_inodes() and find_inode()&iput()
by Zizhi Wo 25 Nov '24

From: Julian Sun <sunjunchao2870(a)gmail.com> stable inclusion from stable-v4.19.322 commit 6cc13a80a26e6b48f78c725c01b91987d61563ef category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IB6P4H Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- commit 88b1afbf0f6b221f6c5bb66cc80cd3b38d696687 upstream. Hi, all Recently I noticed a bug[1] in btrfs, after digged it into and I believe it'a race in vfs. Let's assume there's a inode (ie ino 261) with i_count 1 is called by iput(), and there's a concurrent thread calling generic_shutdown_super(). cpu0: cpu1: iput() // i_count is 1 ->spin_lock(inode) ->dec i_count to 0 ->iput_final() generic_shutdown_super() ->__inode_add_lru() ->evict_inodes() // cause some reason[2] ->if (atomic_read(inode->i_count)) continue; // return before // inode 261 passed the above check // list_lru_add_obj() // and then schedule out ->spin_unlock() // note here: the inode 261 // was still at sb list and hash list, // and I_FREEING|I_WILL_FREE was not been set btrfs_iget() // after some function calls ->find_inode() // found the above inode 261 ->spin_lock(inode) // check I_FREEING|I_WILL_FREE // and passed ->__iget() ->spin_unlock(inode) // schedule back ->spin_lock(inode) // check (I_NEW|I_FREEING|I_WILL_FREE) flags, // passed and set I_FREEING iput() ->spin_unlock(inode) ->spin_lock(inode) ->evict() // dec i_count to 0 ->iput_final() ->spin_unlock() ->evict() Now, we have two threads simultaneously evicting the same inode, which may trigger the BUG(inode->i_state & I_CLEAR) statement both within clear_inode() and iput(). To fix the bug, recheck the inode->i_count after holding i_lock. Because in the most scenarios, the first check is valid, and the overhead of spin_lock() can be reduced. If there is any misunderstanding, please let me know, thanks. [1]: https://lore.kernel.org/linux-btrfs/000000000000eabe1d0619c48986@google.com/ [2]: The reason might be 1. SB_ACTIVE was removed or 2. mapping_shrinkable() return false when I reproduced the bug.
