[PATCH openEuler-1.0-LTS] nilfs2: fix potential kernel bug due to lack of writeback flag waiting
by dinglongwei 02 Jul '24

02 Jul '24

From: Ryusuke Konishi <konishi.ryusuke(a)gmail.com> stable inclusion from stable-v6.1.95 commit 271dcd977ccda8c7a26e360425ae7b4db7d2ecc0 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IA8AE5 CVE: CVE-2024-37078 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit a4ca369ca221bb7e06c725792ac107f0e48e82e7 upstream. Destructive writes to a block device on which nilfs2 is mounted can cause a kernel bug in the folio/page writeback start routine or writeback end routine (__folio_start_writeback in the log below): kernel BUG at mm/page-writeback.c:3070! Oops: invalid opcode: 0000 [#1] PREEMPT SMP KASAN PTI ...

Fix this issue by waiting for ongoing writebacks when putting folios/pages on the backing device into writeback state.

[PATCH openEuler-1.0-LTS] ecryptfs: Fix buffer size for tag 66 packet

From: Brian Kubisiak <brian(a)kubisiak.com> stable inclusion from stable-v4.19.316 commit 1c125b9287e58f364d82174efb167414b92b11f1 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IA6S9H CVE: CVE-2024-38578 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… --------------------------- [ Upstream commit 85a6a1aff08ec9f5b929d345d066e2830e8818e5 ] The 'TAG 66 Packet Format' description is missing the cipher code and checksum fields that are packed into the message packet. As a result, the buffer allocated for the packet is 3 bytes too small and write_tag_66_packet() will write up to 3 bytes past the end of the buffer. Fix this by increasing the size of the allocation so the whole packet will always fit in the buffer. This fixes the below kasan slab-out-of-bounds bug: BUG: KASAN: slab-out-of-bounds in ecryptfs_generate_key_packet_set+0x7d6/0xde0 Write of size 1 at addr ffff88800afbb2a5 by task touch/181 CPU: 0 PID: 181 Comm: touch Not tainted 6.6.13-gnu #1 4c9534092be820851bb687b82d1f92a426598dc6 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.16.2/GNU Guix 04/01/2014 Call Trace: <TASK> dump_stack_lvl+0x4c/0x70 print_report+0xc5/0x610 ? ecryptfs_generate_key_packet_set+0x7d6/0xde0 ? kasan_complete_mode_report_info+0x44/0x210 ? ecryptfs_generate_key_packet_set+0x7d6/0xde0 kasan_report+0xc2/0x110 ? ecryptfs_generate_key_packet_set+0x7d6/0xde0 __asan_store1+0x62/0x80 ecryptfs_generate_key_packet_set+0x7d6/0xde0 ? __pfx_ecryptfs_generate_key_packet_set+0x10/0x10 ? __alloc_pages+0x2e2/0x540 ? __pfx_ovl_open+0x10/0x10 [overlay 30837f11141636a8e1793533a02e6e2e885dad1d] ? dentry_open+0x8f/0xd0 ecryptfs_write_metadata+0x30a/0x550 ? __pfx_ecryptfs_write_metadata+0x10/0x10 ? ecryptfs_get_lower_file+0x6b/0x190 ecryptfs_initialize_file+0x77/0x150 ecryptfs_create+0x1c2/0x2f0 path_openat+0x17cf/0x1ba0 ? __pfx_path_openat+0x10/0x10 do_filp_open+0x15e/0x290 ? __pfx_do_filp_open+0x10/0x10 ? __kasan_check_write+0x18/0x30 ? _raw_spin_lock+0x86/0xf0 ? __pfx__raw_spin_lock+0x10/0x10 ? __kasan_check_write+0x18/0x30 ? alloc_fd+0xf4/0x330 do_sys_openat2+0x122/0x160 ? __pfx_do_sys_openat2+0x10/0x10 __x64_sys_openat+0xef/0x170 ? __pfx___x64_sys_openat+0x10/0x10 do_syscall_64+0x60/0xd0 entry_SYSCALL_64_after_hwframe+0x6e/0xd8 RIP: 0033:0x7f00a703fd67 Code: 25 00 00 41 00 3d 00 00 41 00 74 37 64 8b 04 25 18 00 00 00 85 c0 75 5b 44 89 e2 48 89 ee bf 9c ff ff ff b8 01 01 00 00 0f 05 <48> 3d 00 f0 ff ff 0f 87 85 00 00 00 48 83 c4 68 5d 41 5c c3 0f 1f RSP: 002b:00007ffc088e30b0 EFLAGS: 00000246 ORIG_RAX: 0000000000000101 RAX: ffffffffffffffda RBX: 00007ffc088e3368 RCX: 00007f00a703fd67 RDX: 0000000000000941 RSI: 00007ffc088e48d7 RDI: 00000000ffffff9c RBP: 00007ffc088e48d7 R08: 0000000000000001 R09: 0000000000000000 R10: 00000000000001b6 R11: 0000000000000246 R12: 0000000000000941 R13: 0000000000000000 R14: 00007ffc088e48d7 R15: 00007f00a7180040 </TASK> Allocated by task 181: kasan_save_stack+0x2f/0x60 kasan_set_track+0x29/0x40 kasan_save_alloc_info+0x25/0x40 __kasan_kmalloc+0xc5/0xd0 __kmalloc+0x66/0x160 ecryptfs_generate_key_packet_set+0x6d2/0xde0 ecryptfs_write_metadata+0x30a/0x550 ecryptfs_initialize_file+0x77/0x150 ecryptfs_create+0x1c2/0x2f0 path_openat+0x17cf/0x1ba0 do_filp_open+0x15e/0x290 do_sys_openat2+0x122/0x160 __x64_sys_openat+0xef/0x170 do_syscall_64+0x60/0xd0 entry_SYSCALL_64_after_hwframe+0x6e/0xd8 Fixes: dddfa461fc89 ("[PATCH] eCryptfs: Public key; packet management") Signed-off-by: Brian Kubisiak <brian(a)kubisiak.com> Link: https://lore.kernel.org/r/5j2q56p6qkhezva6b2yuqfrsurmvrrqtxxzrnp3wqu7xrz22i… Signed-off-by: Christian Brauner <brauner(a)kernel.org> Signed-off-by: Sasha Levin <sashal(a)kernel.org> Signed-off-by: Hui Tang <tanghui20(a)huawei.com> --- fs/ecryptfs/keystore.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/fs/ecryptfs/keystore.c b/fs/ecryptfs/keystore.c index e74fe84d0886..e573705a8b97 100644 --- a/fs/ecryptfs/keystore.c +++ b/fs/ecryptfs/keystore.c @@ -314,9 +314,11 @@ write_tag_66_packet(char *signature, u8 cipher_code, * | Key Identifier Size | 1 or 2 bytes | * | Key Identifier | arbitrary | * | File Encryption Key Size | 1 or 2 bytes | + * | Cipher Code | 1 byte | * | File Encryption Key | arbitrary | + * | Checksum | 2 bytes | */ - data_len = (5 + ECRYPTFS_SIG_SIZE_HEX + crypt_stat->key_size); + data_len = (8 + ECRYPTFS_SIG_SIZE_HEX + crypt_stat->key_size); *packet = kmalloc(data_len, GFP_KERNEL); message = *packet; if (!message) { -- 2.34.1

[PATCH openEuler-1.0-LTS] ALSA: timer: Set lower bound of start tick time

From: Takashi Iwai <tiwai(a)suse.de> stable inclusion from stable-v4.19.316 commit 68396c825c43664b20a3a1ba546844deb2b4e48f category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IA6S6Y CVE: CVE-2024-38618 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… --------------------------- commit 4a63bd179fa8d3fcc44a0d9d71d941ddd62f0c4e upstream. Currently ALSA timer doesn't have the lower limit of the start tick time, and it allows a very small size, e.g. 1 tick with 1ns resolution for hrtimer. Such a situation may lead to an unexpected RCU stall, where the callback repeatedly queuing the expire update, as reported by fuzzer. This patch introduces a sanity check of the timer start tick time, so that the system returns an error when a too small start size is set. As of this patch, the lower limit is hard-coded to 100us, which is small enough but can still work somehow.

This is due to ice driver workqueue being allocated with the WQ_MEM_RECLAIM flag and the irdma one is not. According to kernel documentation, this flag should be set if the workqueue will be involved in the kernel's memory reclamation flow. Since it is not, there is no need for the ice driver's WQ to have this flag set so remove it.

[PATCH openEuler-1.0-LTS] usb: fix various gadgets null ptr deref on 10gbps cabling.
by Zheng Zucheng 02 Jul '24

02 Jul '24

From: Maciej Żenczykowski <maze(a)google.com> stable inclusion from stable-v5.10.44 commit 4b289a0f3033f465b4fd51ba995251a7867a2aa2 bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9R4K4 CVE: CVE-2021-47270 -------------------------------- commit 90c4d05780d47e14a50e11a7f17373104cd47d25 upstream. This avoids a null pointer dereference in f_{ecm,eem,hid,loopback,printer,rndis,serial,sourcesink,subset,tcm} by simply reusing the 5gbps config for 10gbps.
