[PATCH OLK-5.10] printk: avoid deadlock in panic
by Ye Weihua 16 Mar '24

16 Mar '24

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I991OV -------------------------------- In the process of load testing against panic, a deadlock issue was discovered. The reason is that in the panic process, console_unlock doesn't handle the printk_context variable evenly, causing printk_context to overflow downwards, allowing vprintk_func to enter the nmi direct branch without disabling interrupt. Upon holding the logbuf_lock lock, an interrupt running wake_up_klogd_work_func was called, resulting in a deadlock. To avoid this issue, move printk_safe_ext_irqrestore after check abandon_console_lock_in_panic().

[PATCH openEuler-1.0-LTS] crypto: algif_aead - fix uninitialized ctx->init
by GUO Zihua 16 Mar '24

16 Mar '24

From: Ondrej Mosnacek <omosnace(a)redhat.com> mainline inclusion from mainline-v5.9-rc1 commit 21dfbcd1f5cbff9cf2f9e7e43475aed8d072b0dd category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I991GQ CVE: NA Reference: https://github.com/torvalds/linux/commit/21dfbcd1f5cbff9cf2f9e7e43475aed8d0… -------------------------------- In skcipher_accept_parent_nokey() the whole af_alg_ctx structure is cleared by memset() after allocation, so add such memset() also to aead_accept_parent_nokey() so that the new "init" field is also initialized to zero. Without that the initial ctx->init checks might randomly return true and cause errors. While there, also remove the redundant zero assignments in both functions. Found via libkcapi testsuite.

[PATCH openEuler-1.0-LTS] llc: call sock_orphan() at release time
by Liu Jian 16 Mar '24

16 Mar '24

From: Eric Dumazet <edumazet(a)google.com> mainline inclusion from mainline-v6.8-rc3 commit aa2b2eb3934859904c287bf5434647ba72e14c1c category: S419 bugzilla: https://gitee.com/src-openeuler/kernel/issues/I96GXM CVE: CVE-2024-26625 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… --------------------------- [ Upstream commit aa2b2eb3934859904c287bf5434647ba72e14c1c ] syzbot reported an interesting trace [1] caused by a stale sk->sk_wq pointer in a closed llc socket. In commit ff7b11aa481f ("net: socket: set sock->sk to NULL after calling proto_ops::release()") Eric Biggers hinted that some protocols are missing a sock_orphan(), we need to perform a full audit. In net-next, I plan to clear sock->sk from sock_orphan() and amend Eric patch to add a warning.

[PATCH OLK-5.10] serial: imx: fix tx statemachine deadlock
by felix 15 Mar '24

15 Mar '24

From: Paul Geurts <paul_geurts(a)live.nl> stable inclusion from stable-v5.10.209 commit 6e04a9d30509fb53ba6df5d655ed61d607a7cfda category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I93EEE CVE: CVE-2023-52456 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 78d60dae9a0c9f09aa3d6477c94047df2fe6f7b0 ] When using the serial port as RS485 port, the tx statemachine is used to control the RTS pin to drive the RS485 transceiver TX_EN pin. When the TTY port is closed in the middle of a transmission (for instance during userland application crash), imx_uart_shutdown disables the interface and disables the Transmission Complete interrupt. afer that, imx_uart_stop_tx bails on an incomplete transmission, to be retriggered by the TC interrupt. This interrupt is disabled and therefore the tx statemachine never transitions out of SEND. The statemachine is in deadlock now, and the TX_EN remains low, making the interface useless. imx_uart_stop_tx now checks for incomplete transmission AND whether TC interrupts are enabled before bailing to be retriggered. This makes sure the state machine handling is reached, and is properly set to WAIT_AFTER_SEND.

This means btrfs_submit_bio() would split the bio, and trigger endio function for both of the two halves. However scrub_submit_initial_read() would only expect the endio function to be called once, not any more. This means the first endio function would already free the bbio::bio, leaving the bvec freed, thus the 2nd endio call would lead to use-after-free. [FIX] - Make sure scrub_read_endio() only updates bits in its range Since we may read less than 64K at the end of the chunk, we should not touch the bits beyond chunk boundary. - Make sure scrub_submit_initial_read() only to read the chunk range This is done by calculating the real number of sectors we need to read, and add sector-by-sector to the bio. Thankfully the scrub read repair path won't need extra fixes: - scrub_stripe_submit_repair_read() With above fixes, we won't update error bit for range beyond chunk, thus scrub_stripe_submit_repair_read() should never submit any read beyond the chunk.

[PATCH OLK-6.6] mm: cachestat: fix folio read-after-free in cache walk

In cachestat, we access the folio from the page cache's xarray to compute its page offset, and check for its dirty and writeback flags. However, we do not hold a reference to the folio before performing these actions, which means the folio can concurrently be released and reused as another folio/page/slab. Get around this altogether by just using xarray's existing machinery for the folio page offsets and dirty/writeback states. This changes behavior for tmpfs files to now always report zeroes in their dirty and writeback counters. This is okay as tmpfs doesn't follow conventional writeback cache behavior: its pages get "cleaned" during swapout, after which they're no longer resident etc. Link: https://lkml.kernel.org/r/20240220153409.GA216065@cmpxchg.org Fixes: cf264e1329fb ("cachestat: implement cachestat syscall") Reported-by: Jann Horn <jannh(a)google.com> Suggested-by: Matthew Wilcox <willy(a)infradead.org> Signed-off-by: Nhat Pham <nphamcs(a)gmail.com> Signed-off-by: Johannes Weiner <hannes(a)cmpxchg.org> Tested-by: Jann Horn <jannh(a)google.com> Cc: <stable(a)vger.kernel.org> [6.4+] Signed-off-by: Andrew Morton <akpm(a)linux-foundation.org> Signed-off-by: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> Signed-off-by: Jinjiang Tu <tujinjiang(a)huawei.com> --- mm/filemap.c | 51 ++++++++++++++++++++++++++------------------------- 1 file changed, 26 insertions(+), 25 deletions(-) diff --git a/mm/filemap.c b/mm/filemap.c index d2aad2ff2892..0ee7db4b22f4 100644 --- a/mm/filemap.c +++ b/mm/filemap.c @@ -4139,28 +4139,40 @@ static void filemap_cachestat(struct address_space *mapping, rcu_read_lock(); xas_for_each(&xas, folio, last_index) { + int order; unsigned long nr_pages; pgoff_t folio_first_index, folio_last_index; + /* + * Don't deref the folio.

[PATCH OLK-5.10] mm/sparsemem: fix race in accessing memory_section->usage
by Peng Zhang 15 Mar '24

15 Mar '24

From: Charan Teja Kalla <quic_charante(a)quicinc.com> mainline inclusion from mainline-v6.8-rc1 commit 5ec8e8ea8b7783fab150cf86404fc38cb4db8800 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I97NHX CVE: CVE-2023-52489 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… ------------------------------------------------------ The below race is observed on a PFN which falls into the device memory region with the system memory configuration where PFN's are such that [ZONE_NORMAL ZONE_DEVICE ZONE_NORMAL]. Since normal zone start and end pfn contains the device memory PFN's as well, the compaction triggered will try on the device memory PFN's too though they end up in NOP(because pfn_to_online_page() returns NULL for ZONE_DEVICE memory sections). When from other core, the section mappings are being removed for the ZONE_DEVICE region, that the PFN in question belongs to, on which compaction is currently being operated is resulting into the kernel crash with CONFIG_SPASEMEM_VMEMAP enabled. The crash logs can be seen at [1]. compact_zone() memunmap_pages ------------- --------------- __pageblock_pfn_to_page ...... (a)pfn_valid(): valid_section()//return true (b)__remove_pages()-> sparse_remove_section()-> section_deactivate(): [Free the array ms->usage and set ms->usage = NULL] pfn_section_valid() [Access ms->usage which is NULL] NOTE: From the above it can be said that the race is reduced to between the pfn_valid()/pfn_section_valid() and the section deactivate with SPASEMEM_VMEMAP enabled. The commit b943f045a9af("mm/sparse: fix kernel crash with pfn_section_valid check") tried to address the same problem by clearing the SECTION_HAS_MEM_MAP with the expectation of valid_section() returns false thus ms->usage is not accessed. Fix this issue by the below steps: a) Clear SECTION_HAS_MEM_MAP before freeing the ->usage. b) RCU protected read side critical section will either return NULL when SECTION_HAS_MEM_MAP is cleared or can successfully access ->usage. c) Free the ->usage with kfree_rcu() and set ms->usage = NULL. No attempt will be made to access ->usage after this as the SECTION_HAS_MEM_MAP is cleared thus valid_section() return false. Thanks to David/Pavan for their inputs on this patch. [1] https://lore.kernel.org/linux-mm/994410bb-89aa-d987-1f50-f514903c55aa@quici… On Snapdragon SoC, with the mentioned memory configuration of PFN's as [ZONE_NORMAL ZONE_DEVICE ZONE_NORMAL], we are able to see bunch of issues daily while testing on a device farm. For this particular issue below is the log. Though the below log is not directly pointing to the pfn_section_valid(){ ms->usage;}, when we loaded this dump on T32 lauterbach tool, it is pointing.
