[PATCH OLK-6.6] mm, fs: Add BPF_READAHEAD_OPTIMIZATION option for bpf readhead
by ZhaoLong Wang 15 Apr '24

15 Apr '24

hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I7Y9JD CVE: NA --------------------------- This patch introduces a new configuration option called BPF_READAHEAD_OPTIMIZATION, which is designed to optimize the read performance in Spark SQL scenarios using eBPF to implement a programmable kernel. The changes include: - Add CONFIG_BPF_READAHEAD_OPTIMIZATION to mm/Kconfig, which depends on CONFIG_TRACEPOINTS. - Add conditional compilation directives to fs/ext4/file.c, fs/read_write.c, fs/xfs/xfs_file.c, and include/linux/fs.h to include tracepoint-related headers and functions only when BPF_READAHEAD_OPTIMIZATION is enabled. - Miodify page_cache_sync_ra() in mm/readahead.c to disable forced readahead when BPF_READAHEAD_OPTIMIZATION is not enabled. V2: Explicitly set CONFIG_ in openeuler_defconfig. Do not add redundant macros to mm/readahead. V3: Place all macro isolation switches in the .h header file.

[PATCH OLK-5.10] drm/amd/display: Wake DMCUB before executing GPINT commands
by Zhu Wang 15 Apr '24

15 Apr '24

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.

[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
by Zhu Wang 15 Apr '24

15 Apr '24

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.

Create wrappers that add locking for paths outside of the core interrupt code. In particular, irq_type is updated holding igate, therefore testing is_intx() requires holding igate. For example clearing DisINTx from config space can otherwise race changes of the interrupt configuration. 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 openEuler-1.0-LTS] vfio/pci: Disable auto-enable of exclusive INTx IRQ

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] netlink: Fix kernel-infoleak-after-free in __skb_datagram_iter

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 openEuler-1.0-LTS] netlink: Fix kernel-infoleak-after-free in __skb_datagram_iter
by Zhengchao Shao 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.

From: Pablo Neira Ayuso <pablo(a)netfilter.org> stable inclusion from stable-v5.10.210 commit 9489e214ea8f2a90345516016aa51f2db3a8cc2f category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9E49K CVE: CVE-2024-26808 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 01acb2e8666a6529697141a6017edbf206921913 upstream. Remove netdevice from inet/ingress basechain in case NETDEV_UNREGISTER event is reported, otherwise a stale reference to netdevice remains in the hook list.

[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.

The splat occurs because skb->data points past skb->head allocated area. This is because neigh layer does: __skb_pull(skb, skb_network_offset(skb)); ... but skb_network_offset() returns a negative offset and __skb_pull() arg is unsigned. IOW, we skb->data gets "adjusted" by a huge value. The negative value is returned because skb->head and skb->data distance is more than 64k and skb->network_header (u16) has wrapped around. The bug is in the ip_tunnel infrastructure, which can cause dev->needed_headroom to increment ad infinitum. The syzkaller reproducer consists of packets getting routed via a gre tunnel, and route of gre encapsulated packets pointing at another (ipip) tunnel. The ipip encapsulation finds gre0 as next output device. This results in the following pattern: 1). First packet is to be sent out via gre0. Route lookup found an output device, ipip0. 2). ip_tunnel_xmit for gre0 bumps gre0->needed_headroom based on the future output device, rt.dev->needed_headroom (ipip0). 3). ip output / start_xmit moves skb on to ipip0. which runs the same code path again (xmit recursion). 4). Routing step for the post-gre0-encap packet finds gre0 as output device to use for ipip0 encapsulated packet. tunl0->needed_headroom is then incremented based on the (already bumped) gre0 device headroom. This repeats for every future packet: gre0->needed_headroom gets inflated because previous packets' ipip0 step incremented rt->dev (gre0) headroom, and ipip0 incremented because gre0 needed_headroom was increased. For each subsequent packet, gre/ipip0->needed_headroom grows until post-expand-head reallocations result in a skb->head/data distance of more than 64k. Once that happens, skb->network_header (u16) wraps around when pskb_expand_head tries to make sure that skb_network_offset() is unchanged after the headroom expansion/reallocation. After this skb_network_offset(skb) returns a different (and negative) result post headroom expansion. The next trip to neigh layer (or anything else that would __skb_pull the network header) makes skb->data point to a memory location outside skb->head area. v2: Cap the needed_headroom update to an arbitarily chosen upperlimit to prevent perpetual increase instead of dropping the headroom increment completely.

[PATCH OLK-5.10] hv_netvsc: Fix race condition between netvsc_probe and netvsc_remove
by Ziyang Xuan 12 Apr '24

12 Apr '24

From: Souradeep Chakrabarti <schakrabarti(a)linux.microsoft.com> stable inclusion from stable-v5.10.210 commit 9ec807e7b6f5fcf9499f3baa69f254bb239a847f category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9E2GU CVE: CVE-2024-26698 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit e0526ec5360a48ad3ab2e26e802b0532302a7e11 upstream. In commit ac5047671758 ("hv_netvsc: Disable NAPI before closing the VMBus channel"), napi_disable was getting called for all channels, including all subchannels without confirming if they are enabled or not. This caused hv_netvsc getting hung at napi_disable, when netvsc_probe() has finished running but nvdev->subchan_work has not started yet. netvsc_subchan_work() -> rndis_set_subchannel() has not created the sub-channels and because of that netvsc_sc_open() is not running. netvsc_remove() calls cancel_work_sync(&nvdev->subchan_work), for which netvsc_subchan_work did not run. netif_napi_add() sets the bit NAPI_STATE_SCHED because it ensures NAPI cannot be scheduled. Then netvsc_sc_open() -> napi_enable will clear the NAPIF_STATE_SCHED bit, so it can be scheduled. napi_disable() does the opposite. Now during netvsc_device_remove(), when napi_disable is called for those subchannels, napi_disable gets stuck on infinite msleep. This fix addresses this problem by ensuring that napi_disable() is not getting called for non-enabled NAPI struct. But netif_napi_del() is still necessary for these non-enabled NAPI struct for cleanup purpose.

[PATCH openEuler-22.03-LTS] mm/swap: fix race when skipping swapcache
by Jinjiang Tu 12 Apr '24

12 Apr '24

From: Kairui Song <kasong(a)tencent.com> mainline inclusion from mainline-v6.8-rc6 commit 13ddaf26be324a7f951891ecd9ccd04466d27458 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9E2M2 CVE: CVE-2024-26759 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… ------------------------------------------- When skipping swapcache for SWP_SYNCHRONOUS_IO, if two or more threads swapin the same entry at the same time, they get different pages (A, B). Before one thread (T0) finishes the swapin and installs page (A) to the PTE, another thread (T1) could finish swapin of page (B), swap_free the entry, then swap out the possibly modified page reusing the same entry. It breaks the pte_same check in (T0) because PTE value is unchanged, causing ABA problem. Thread (T0) will install a stalled page (A) into the PTE and cause data corruption. One possible callstack is like this: CPU0 CPU1 ---- ---- do_swap_page() do_swap_page() with same entry <direct swapin path> <direct swapin path> <alloc page A> <alloc page B> swap_read_folio() <- read to page A swap_read_folio() <- read to page B <slow on later locks or interrupt> <finished swapin first> ... set_pte_at() swap_free() <- entry is free <write to page B, now page A stalled> <swap out page B to same swap entry> pte_same() <- Check pass, PTE seems unchanged, but page A is stalled! swap_free() <- page B content lost! set_pte_at() <- staled page A installed! And besides, for ZRAM, swap_free() allows the swap device to discard the entry content, so even if page (B) is not modified, if swap_read_folio() on CPU0 happens later than swap_free() on CPU1, it may also cause data loss. To fix this, reuse swapcache_prepare which will pin the swap entry using the cache flag, and allow only one thread to swap it in, also prevent any parallel code from putting the entry in the cache. Release the pin after PT unlocked. Racers just loop and wait since it's a rare and very short event. A schedule_timeout_uninterruptible(1) call is added to avoid repeated page faults wasting too much CPU, causing livelock or adding too much noise to perf statistics. A similar livelock issue was described in commit 029c4628b2eb ("mm: swap: get rid of livelock in swapin readahead") Reproducer: This race issue can be triggered easily using a well constructed reproducer and patched brd (with a delay in read path) [1]: With latest 6.8 mainline, race caused data loss can be observed easily: $ gcc -g -lpthread test-thread-swap-race.c && ./a.out Polulating 32MB of memory region... Keep swapping out... Starting round 0... Spawning 65536 workers... 32746 workers spawned, wait for done... Round 0: Error on 0x5aa00, expected 32746, got 32743, 3 data loss! Round 0: Error on 0x395200, expected 32746, got 32743, 3 data loss! Round 0: Error on 0x3fd000, expected 32746, got 32737, 9 data loss! Round 0 Failed, 15 data loss! This reproducer spawns multiple threads sharing the same memory region using a small swap device. Every two threads updates mapped pages one by one in opposite direction trying to create a race, with one dedicated thread keep swapping out the data out using madvise. The reproducer created a reproduce rate of about once every 5 minutes, so the race should be totally possible in production. After this patch, I ran the reproducer for over a few hundred rounds and no data loss observed.

[PATCH openEuler-1.0-LTS] nilfs2: fix data corruption in dsync block recovery for small block sizes
by Zizhi Wo 12 Apr '24

12 Apr '24

From: Ryusuke Konishi <konishi.ryusuke(a)gmail.com> stable inclusion from stable-v4.19.307 commit 5278c3eb6bf5896417572b52adb6be9d26e92f65 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9E2FH CVE: CVE-2024-26697 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 67b8bcbaed4777871bb0dcc888fb02a614a98ab1 upstream. The helper function nilfs_recovery_copy_block() of nilfs_recovery_dsync_blocks(), which recovers data from logs created by data sync writes during a mount after an unclean shutdown, incorrectly calculates the on-page offset when copying repair data to the file's page cache. In environments where the block size is smaller than the page size, this flaw can cause data corruption and leak uninitialized memory bytes during the recovery process. Fix these issues by correcting this byte offset calculation on the page.
