From: Pablo Neira Ayuso <pablo(a)netfilter.org> stable inclusion from stable-v5.10.186 commit 2a90da8e0dd50f42e577988f4219f4f4cd3616b7 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9L5O8 CVE: CVE-2024-27017 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 2b84e215f87443c74ac0aa7f76bb172d43a87033 ] The .walk callback iterates over the current active set, but it might be useful to iterate over the next generation set. Use the generation mask to determine what set view (either current or next generation) is use for the walk iteration.

[PATCH OLK-5.10] usb: gadget: ncm: Avoid dropping datagrams of properly parsed NTBs
by Guo Mengqi 25 Jun '24

25 Jun '24

From: Krishna Kurapati <quic_kriskura(a)quicinc.com> stable inclusion from stable-v5.10.211 commit 57ca0e16f393bb21d69734e536e383a3a4c665fd category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9Q8M7 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 76c51146820c5dac629f21deafab0a7039bc3ccd upstream. It is observed sometimes when tethering is used over NCM with Windows 11 as host, at some instances, the gadget_giveback has one byte appended at the end of a proper NTB. When the NTB is parsed, unwrap call looks for any leftover bytes in SKB provided by u_ether and if there are any pending bytes, it treats them as a separate NTB and parses it. But in case the second NTB (as per unwrap call) is faulty/corrupt, all the datagrams that were parsed properly in the first NTB and saved in rx_list are dropped. Adding a few custom traces showed the following: [002] d..1 7828.532866: dwc3_gadget_giveback: ep1out: req 000000003868811a length 1025/16384 zsI ==> 0 [002] d..1 7828.532867: ncm_unwrap_ntb: K: ncm_unwrap_ntb toprocess: 1025 [002] d..1 7828.532867: ncm_unwrap_ntb: K: ncm_unwrap_ntb nth: 1751999342 [002] d..1 7828.532868: ncm_unwrap_ntb: K: ncm_unwrap_ntb seq: 0xce67 [002] d..1 7828.532868: ncm_unwrap_ntb: K: ncm_unwrap_ntb blk_len: 0x400 [002] d..1 7828.532868: ncm_unwrap_ntb: K: ncm_unwrap_ntb ndp_len: 0x10 [002] d..1 7828.532869: ncm_unwrap_ntb: K: Parsed NTB with 1 frames In this case, the giveback is of 1025 bytes and block length is 1024. The rest 1 byte (which is 0x00) won't be parsed resulting in drop of all datagrams in rx_list. Same is case with packets of size 2048: [002] d..1 7828.557948: dwc3_gadget_giveback: ep1out: req 0000000011dfd96e length 2049/16384 zsI ==> 0 [002] d..1 7828.557949: ncm_unwrap_ntb: K: ncm_unwrap_ntb nth: 1751999342 [002] d..1 7828.557950: ncm_unwrap_ntb: K: ncm_unwrap_ntb blk_len: 0x800 Lecroy shows one byte coming in extra confirming that the byte is coming in from PC: Transfer 2959 - Bytes Transferred(1025) Timestamp((18.524 843 590) - Transaction 8391 - Data(1025 bytes) Timestamp(18.524 843 590) --- Packet 4063861 Data(1024 bytes) Duration(2.117us) Idle(14.700ns) Timestamp(18.524 843 590) --- Packet 4063863 Data(1 byte) Duration(66.160ns) Time(282.000ns) Timestamp(18.524 845 722) According to Windows driver, no ZLP is needed if wBlockLength is non-zero, because the non-zero wBlockLength has already told the function side the size of transfer to be expected. However, there are in-market NCM devices that rely on ZLP as long as the wBlockLength is multiple of wMaxPacketSize. To deal with such devices, it pads an extra 0 at end so the transfer is no longer multiple of wMaxPacketSize.

This is problematic because infrastructure like syzkaller has no idea that this message indicates a bug. In addition, some people explicitly want their kernels to BUG() when kernel data corruption has been detected (CONFIG_BUG_ON_DATA_CORRUPTION). And finally, when generic_shutdown_super() detects remaining inodes on a system without CONFIG_BUG_ON_DATA_CORRUPTION, it would be nice if later accesses to a busy inode would at least crash somewhat cleanly rather than walking through freed memory. To address all three, use CHECK_DATA_CORRUPTION() when kernel bugs are detected.

To deal with such devices, it pads an extra 0 at end so the transfer is no longer multiple of wMaxPacketSize.

To deal with such devices, it pads an extra 0 at end so the transfer is no longer multiple of wMaxPacketSize.

[PATCH openEuler-1.0-LTS] mm/migrate: set swap entry values of THP tail pages properly.
by Liu Shixin 25 Jun '24

25 Jun '24

From: Zi Yan <ziy(a)nvidia.com> stable inclusion from stable-v4.19.312 commit 9e92cefdaa7537515dc0ff6cc73d46fa31b062fc category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IA82S5 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- The tail pages in a THP can have swap entry information stored in their private field. When migrating to a new page, all tail pages of the new page need to update ->private to avoid future data corruption. This fix is stable-only, since after commit 07e09c483cbe ("mm/huge_memory: work on folio->swap instead of page->private when splitting folio"), subpages of a swapcached THP no longer requires the maintenance. Adding THPs to the swapcache was introduced in commit 38d8b4e6bdc87 ("mm, THP, swap: delay splitting THP during swap out"), where each subpage of a THP added to the swapcache had its own swapcache entry and required the ->private field to point to the correct swapcache entry. Later, when THP migration functionality was implemented in commit 616b8371539a6 ("mm: thp: enable thp migration in generic path"), it initially did not handle the subpages of swapcached THPs, failing to update their ->private fields or replace the subpage pointers in the swapcache. Subsequently, commit e71769ae5260 ("mm: enable thp migration for shmem thp") addressed the swapcache update aspect. This patch fixes the update of subpage ->private fields.

[PATCH OLK-6.6] mm: drop the 'anon_' prefix for swap-out mTHP counters
by Liu Shixin 25 Jun '24

25 Jun '24

From: Baolin Wang <baolin.wang(a)linux.alibaba.com> mainline inclusion from mainline-v6.10-rc3 commit 0d648dd5c899f33154b98a6aef6e3dab0f4de613 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IA7H2V CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- The mTHP swap related counters: 'anon_swpout' and 'anon_swpout_fallback' are confusing with an 'anon_' prefix, since the shmem can swap out non-anonymous pages. So drop the 'anon_' prefix to keep consistent with the old swap counter names. This is needed in 6.10-rcX to avoid having an inconsistent ABI out in the field.

[PATCH openEuler-22.03-LTS-SP1] kprobes: Fix possible use-after-free issue on kprobe registration
by Chen Zhongjin 25 Jun '24

25 Jun '24

From: Zheng Yejian <zhengyejian1(a)huawei.com> stable inclusion from stable-v5.10.216 commit 5062d1f4f07facbdade0f402d9a04a788f52e26d category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9QRI5 CVE: CVE-2024-35955 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 325f3fb551f8cd672dbbfc4cf58b14f9ee3fc9e8 upstream. When unloading a module, its state is changing MODULE_STATE_LIVE -> MODULE_STATE_GOING -> MODULE_STATE_UNFORMED. Each change will take a time. `is_module_text_address()` and `__module_text_address()` works with MODULE_STATE_LIVE and MODULE_STATE_GOING. If we use `is_module_text_address()` and `__module_text_address()` separately, there is a chance that the first one is succeeded but the next one is failed because module->state becomes MODULE_STATE_UNFORMED between those operations. In `check_kprobe_address_safe()`, if the second `__module_text_address()` is failed, that is ignored because it expected a kernel_text address. But it may have failed simply because module->state has been changed to MODULE_STATE_UNFORMED. In this case, arm_kprobe() will try to modify non-exist module text address (use-after-free). To fix this problem, we should not use separated `is_module_text_address()` and `__module_text_address()`, but use only `__module_text_address()` once and do `try_module_get(module)` which is only available with MODULE_STATE_LIVE.

[PATCH] mm: drop the 'anon_' prefix for swap-out mTHP counters

From: Baolin Wang <baolin.wang(a)linux.alibaba.com> mainline inclusion from mainline-v6.10-rc3 commit 0d648dd5c899f33154b98a6aef6e3dab0f4de613 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IA7H2V CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- The mTHP swap related counters: 'anon_swpout' and 'anon_swpout_fallback' are confusing with an 'anon_' prefix, since the shmem can swap out non-anonymous pages.

by Chen Zhongjin 25 Jun '24

25 Jun '24

From: Zheng Yejian <zhengyejian1(a)huawei.com> stable inclusion from stable-v5.10.216 commit 5062d1f4f07facbdade0f402d9a04a788f52e26d category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9QRI5 CVE: CVE-2024-35955 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 325f3fb551f8cd672dbbfc4cf58b14f9ee3fc9e8 upstream. When unloading a module, its state is changing MODULE_STATE_LIVE -> MODULE_STATE_GOING -> MODULE_STATE_UNFORMED. Each change will take a time. `is_module_text_address()` and `__module_text_address()` works with MODULE_STATE_LIVE and MODULE_STATE_GOING. If we use `is_module_text_address()` and `__module_text_address()` separately, there is a chance that the first one is succeeded but the next one is failed because module->state becomes MODULE_STATE_UNFORMED between those operations. In `check_kprobe_address_safe()`, if the second `__module_text_address()` is failed, that is ignored because it expected a kernel_text address. But it may have failed simply because module->state has been changed to MODULE_STATE_UNFORMED. In this case, arm_kprobe() will try to modify non-exist module text address (use-after-free). To fix this problem, we should not use separated `is_module_text_address()` and `__module_text_address()`, but use only `__module_text_address()` once and do `try_module_get(module)` which is only available with MODULE_STATE_LIVE.

From: Justin Green <greenjustin(a)chromium.org> stable inclusion from -v4.19.316 commit 79078880795478d551a05acc41f957700030d364 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IA6S8E CVE: CVE-2024-38549 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 1e4350095e8ab2577ee05f8c3b044e661b5af9a0 ] Add a check to mtk_drm_gem_init if we attempt to allocate a GEM object of 0 bytes. Currently, no such check exists and the kernel will panic if a userspace application attempts to allocate a 0x0 GBM buffer. Tested by attempting to allocate a 0x0 GBM buffer on an MT8188 and verifying that we now return EINVAL. Fixes: 119f5173628a ("drm/mediatek: Add DRM Driver for Mediatek SoC MT8173.")
