[PATCH OLK-5.10] vfio/pci: Disable auto-enable of exclusive INTx IRQ
by Jinjie Ruan 15 Apr '24

15 Apr '24

From: Alex Williamson <alex.williamson(a)redhat.com> stable inclusion from stable-v5.15.154 commit b7a2f0955ffceffadfe098b40b50307431f45438 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9E6TU CVE: CVE-2024-27437 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit fe9a7082684eb059b925c535682e68c34d487d43 ] Currently for devices requiring masking at the irqchip for INTx, ie. devices without DisINTx support, the IRQ is enabled in request_irq() and subsequently disabled as necessary to align with the masked status flag. This presents a window where the interrupt could fire between these events, resulting in the IRQ incrementing the disable depth twice. This would be unrecoverable for a user since the masked flag prevents nested enables through vfio. Instead, invert the logic using IRQF_NO_AUTOEN such that exclusive INTx is never auto-enabled, then unmask as required.

[PATCH OLK-5.10] drm/amd/display: Wake DMCUB before executing GPINT commands

From: Nicholas Kazlauskas <nicholas.kazlauskas(a)amd.com> stable inclusion from stable-v6.7.3 commit 2ef98c6d753a744e333b7e34b9cf687040fba57d category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9BV4C CVE: CVE-2023-52624 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- [ Upstream commit e5ffd1263dd5b44929c676171802e7b6af483f21 ] [Why] DMCUB can be in idle when we attempt to interface with the HW through the GPINT mailbox resulting in a system hang. [How] Add dc_wake_and_execute_gpint() to wrap the wake, execute, sleep sequence. If the GPINT executes successfully then DMCUB will be put back into sleep after the optional response is returned. It functions similar to the inbox command interface.

From: Alex Williamson <alex.williamson(a)redhat.com> stable inclusion from stable-v5.15.154 commit b7a2f0955ffceffadfe098b40b50307431f45438 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9E6TU CVE: CVE-2024-27437 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit fe9a7082684eb059b925c535682e68c34d487d43 ] Currently for devices requiring masking at the irqchip for INTx, ie. devices without DisINTx support, the IRQ is enabled in request_irq() and subsequently disabled as necessary to align with the masked status flag. This presents a window where the interrupt could fire between these events, resulting in the IRQ incrementing the disable depth twice. This would be unrecoverable for a user since the masked flag prevents nested enables through vfio. Instead, invert the logic using IRQF_NO_AUTOEN such that exclusive INTx is never auto-enabled, then unmask as required.

This aligns interfaces which may trigger the INTx eventfd into two camps, one side serialized by igate and the other only enabled while INTx is configured. A subsequent patch introduces synchronization for the latter flows.

[PATCH OLK-5.10] net/sched: act_mirred: don't override retval if we already lost the skb

From: Jakub Kicinski <kuba(a)kernel.org> mainline inclusion from mainline-v6.8-rc6 commit 166c2c8a6a4dc2e4ceba9e10cfe81c3e469e3210 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9E2LZ CVE: CVE-2024-26739 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- If we're redirecting the skb, and haven't called tcf_mirred_forward(), yet, we need to tell the core to drop the skb by setting the retcode to SHOT. If we have called tcf_mirred_forward(), however, the skb is out of our hands and returning SHOT will lead to UaF. Move the retval override to the error path which actually need it.

[PATCH openEuler-1.0-LTS] netlink: Fix kernel-infoleak-after-free in __skb_datagram_iter
by Zhengchao Shao 14 Apr '24

14 Apr '24

From: Ryosuke Yasuoka <ryasuoka(a)redhat.com> stable inclusion from stable-v4.19.309 commit ec343a55b687a452f5e87f3b52bf9f155864df65 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9E46W CVE: CVE-2024-26805 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 661779e1fcafe1b74b3f3fe8e980c1e207fea1fd ] syzbot reported the following uninit-value access issue [1]: netlink_to_full_skb() creates a new `skb` and puts the `skb->data` passed as a 1st arg of netlink_to_full_skb() onto new `skb`. The data size is specified as `len` and passed to skb_put_data(). This `len` is based on `skb->end` that is not data offset but buffer offset. The `skb->end` contains data and tailroom. Since the tailroom is not initialized when the new `skb` created, KMSAN detects uninitialized memory area when copying the data. This patch resolved this issue by correct the len from `skb->end` to `skb->len`, which is the actual data offset.

[PATCH OLK-5.10] netlink: Fix kernel-infoleak-after-free in __skb_datagram_iter
by Zhengchao Shao 14 Apr '24

14 Apr '24

From: Ryosuke Yasuoka <ryasuoka(a)redhat.com> stable inclusion from stable-v5.10.212 commit f19d1f98e60e68b11fc60839105dd02a30ec0d77 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9E46W CVE: CVE-2024-26805 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 661779e1fcafe1b74b3f3fe8e980c1e207fea1fd ] syzbot reported the following uninit-value access issue [1]: netlink_to_full_skb() creates a new `skb` and puts the `skb->data` passed as a 1st arg of netlink_to_full_skb() onto new `skb`. The data size is specified as `len` and passed to skb_put_data(). This `len` is based on `skb->end` that is not data offset but buffer offset. The `skb->end` contains data and tailroom. Since the tailroom is not initialized when the new `skb` created, KMSAN detects uninitialized memory area when copying the data. This patch resolved this issue by correct the len from `skb->end` to `skb->len`, which is the actual data offset.

[PATCH OLK-6.6 0/2] mm: batch mm counter updating in filemap_map_pages()

From: ZhangPeng <zhangpeng362(a)huawei.com> Like copy_pte_range()/zap_pte_range(), make mm counter batch updating in filemap_map_pages(), since folios type are same(MM_SHMEMPAGES or MM_FILEPAGES) in filemap_map_pages(), only check the first folio type is enough, the 'lat_pagefault -P 1 file' test from lmbench shows 12% improvement, and the percpu_counter_add_batch() is gone from perf flame graph.
