[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.

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 openEuler-22.03-LTS-SP1 5/6] bnxt_en: Implement .set_port / .unset_port UDP tunnel callbacks

From: Somnath Kotur <somnath.kotur(a)broadcom.com> stable inclusion from stable-v5.10.184 commit 3f6dfff5fe416bda6469cf235eaa9c54fee2a0bc category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8L4MY Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 1eb4ef12591348c440ac9d6efcf7521e73cf2b10 ] As per the new udp tunnel framework, drivers which need to know the details of a port entry (i.e. port type) when it gets deleted should use the .set_port / .unset_port callbacks. Implementing the current .udp_tunnel_sync callback would mean that the deleted tunnel port entry would be all zeros. This used to work on older firmware because it would not check the input when deleting a tunnel port. With newer firmware, the delete will now fail and subsequent tunnel port allocation will fail as a result.

[PATCH openEuler-22.03-LTS-SP1 4/6] bnxt_en: Query default VLAN before VNIC setup on a VF

From: Somnath Kotur <somnath.kotur(a)broadcom.com> stable inclusion from stable-v5.10.184 commit deead0d8729f33f47cbedd0010a7e0e381527f9b category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8L4MY Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 1a9e4f501bc6ff1b6ecb60df54fbf2b54db43bfe ] We need to call bnxt_hwrm_func_qcfg() on a VF to query the default VLAN that may be setup by the PF. If a default VLAN is enabled, the VF cannot support VLAN acceleration on the receive side and the VNIC must be setup to strip out the default VLAN tag. If a default VLAN is not enabled, the VF can support VLAN acceleration on the receive side. The VNIC should be set up to strip or not strip the VLAN based on the RX VLAN acceleration setting. Without this call to determine the default VLAN before calling bnxt_setup_vnic(), the VNIC may not be set up correctly. For example, bnxt_setup_vnic() may set up to strip the VLAN tag based on stale default VLAN information. If RX VLAN acceleration is not enabled, the VLAN tag will be incorrectly stripped and the RX data path will not work correctly.

[PATCH OLK-6.6] iommu/iova: avoid softlockup in fq_flush_timeout

Call trace: _raw_spin_unlock_irqrestore+0x14/0x78 call_timer_fn+0x3c/0x1d0 expire_timers+0xcc/0x190 run_timer_softirq+0xfc/0x268 __do_softirq+0x128/0x3dc ____do_softirq+0x18/0x30 call_on_irq_stack+0x24/0x30 do_softirq_own_stack+0x24/0x38 irq_exit_rcu+0xc0/0xe8 el1_interrupt+0x48/0xc0 el1h_64_irq_handler+0x18/0x28 el1h_64_irq+0x78/0x80 __schedule+0xf28/0x12a0 schedule+0x3c/0x108 schedule_timeout+0xa0/0x1d0 pktgen_thread_worker+0x1180/0x15d0 kthread+0x120/0x130 ret_from_fork+0x10/0x20 This is because the timer callback fq_flush_timeout may run more than 10ms, and timer may be processed continuously in the softirq so trigger softlockup. We can use work to deal with fq_ring_free for each cpu which may take long time, that to avoid triggering softlockup.
