[merged mm-nonmm-stable] hfs-fix-missing-hfs_bnode_get-in-__hfs_bnode_create.patch removed from -mm tree

The quilt patch titled Subject: hfs: fix missing hfs_bnode_get() in __hfs_bnode_create has been removed from the -mm tree. Its filename was hfs-fix-missing-hfs_bnode_get-in-__hfs_bnode_create.patch This patch was dropped because it was merged into the mm-nonmm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Liu Shixin <liushixin2(a)huawei.com> Subject: hfs: fix missing hfs_bnode_get() in __hfs_bnode_create Date: Mon, 12 Dec 2022 10:16:27 +0800 Syzbot found a kernel BUG in hfs_bnode_put(): kernel BUG at fs/hfs/bnode.c:466! invalid opcode: 0000 [#1] PREEMPT SMP KASAN CPU: 0 PID: 3634 Comm: kworker/u4:5 Not tainted 6.1.0-rc7-syzkaller-00190-g97ee9d1c1696 #0 Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 10/26/2022 Workqueue: writeback wb_workfn (flush-7:0) RIP: 0010:hfs_bnode_put+0x46f/0x480 fs/hfs/bnode.c:466 Code: 8a 80 ff e9 73 fe ff ff 89 d9 80 e1 07 80 c1 03 38 c1 0f 8c a0 fe ff ff 48 89 df e8 db 8a 80 ff e9 93 fe ff ff e8 a1 68 2c ff <0f> 0b e8 9a 68 2c ff 0f 0b 0f 1f 84 00 00 00 00 00 55 41 57 41 56 RSP: 0018:ffffc90003b4f258 EFLAGS: 00010293 RAX: ffffffff825e318f RBX: 0000000000000000 RCX: ffff8880739dd7c0 RDX: 0000000000000000 RSI: 0000000000000000 RDI: 0000000000000000 RBP: ffffc90003b4f430 R08: ffffffff825e2d9b R09: ffffed10045157d1 R10: ffffed10045157d1 R11: 1ffff110045157d0 R12: ffff8880228abe80 R13: ffff88807016c000 R14: dffffc0000000000 R15: ffff8880228abe00 FS: 0000000000000000(0000) GS:ffff8880b9800000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007fa6ebe88718 CR3: 000000001e93d000 CR4: 00000000003506f0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Call Trace: <TASK> hfs_write_inode+0x1bc/0xb40 write_inode fs/fs-writeback.c:1440 [inline] __writeback_single_inode+0x4d6/0x670 fs/fs-writeback.c:1652 writeback_sb_inodes+0xb3b/0x18f0 fs/fs-writeback.c:1878 __writeback_inodes_wb+0x125/0x420 fs/fs-writeback.c:1949 wb_writeback+0x440/0x7b0 fs/fs-writeback.c:2054 wb_check_start_all fs/fs-writeback.c:2176 [inline] wb_do_writeback fs/fs-writeback.c:2202 [inline] wb_workfn+0x827/0xef0 fs/fs-writeback.c:2235 process_one_work+0x877/0xdb0 kernel/workqueue.c:2289 worker_thread+0xb14/0x1330 kernel/workqueue.c:2436 kthread+0x266/0x300 kernel/kthread.c:376 ret_from_fork+0x1f/0x30 arch/x86/entry/entry_64.S:306 </TASK> The BUG_ON() is triggered at here: /* Dispose of resources used by a node */ void hfs_bnode_put(struct hfs_bnode *node) { if (node) { <skipped> BUG_ON(!atomic_read(&node->refcnt)); <- we have issue here!!!! <skipped> } } By tracing the refcnt, I found the node is created by hfs_bmap_alloc() with refcnt 1. Then the node is used by hfs_btree_write(). There is a missing of hfs_bnode_get() after find the node. The issue happened in following path: <alloc> hfs_bmap_alloc hfs_bnode_find __hfs_bnode_create <- allocate a new node with refcnt 1. hfs_bnode_put <- decrease the refcnt <write> hfs_btree_write hfs_bnode_find __hfs_bnode_create hfs_bnode_findhash <- find the node without refcnt increased. hfs_bnode_put <- trigger the BUG_ON() since refcnt is 0.

[PATCH] fscrypt: Copy the memcg information to the ciphertext page

by Matthew Wilcox (Oracle)

Both f2fs and ext4 end up passing the ciphertext page to wbc_account_cgroup_owner(). At the moment, the ciphertext page appears to belong to no cgroup, so it is accounted to the root_mem_cgroup instead of whatever cgroup the original page was in. It's hard to say how far back this is a bug. The crypto code shared between ext4 & f2fs was created in May 2015 with commit 0b81d0779072, but neither filesystem did anything with memcg_data before then. memcg writeback accounting was added to ext4 in July 2015 in commit 001e4a8775f6 and it wasn't added to f2fs until January 2018 (commit 578c647879f7). I'm going with the ext4 commit since this is the first commit where there was a difference in behaviour between encrypted and unencrypted filesystems.

patch "bus: mhi: ep: Change state_lock to mutex" added to char-misc-next

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled bus: mhi: ep: Change state_lock to mutex to my char-misc git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-next branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will also be merged in the next major kernel release during the merge window. If you have any questions about this process, please let me know. From 1ddc7618294084fff8d673217a9479550990ee84 Mon Sep 17 00:00:00 2001 From: Manivannan Sadhasivam <manivannan.sadhasivam(a)linaro.org> Date: Mon, 23 Jan 2023 12:59:45 +0530 Subject: bus: mhi: ep: Change state_lock to mutex state_lock, the spinlock type is meant to protect race against concurrent MHI state transitions. In mhi_ep_set_m0_state(), while the state_lock is being held, the channels are resumed in mhi_ep_resume_channels() if the previous state was M3. This causes sleeping in atomic bug, since mhi_ep_resume_channels() use mutex internally. Since the state_lock is supposed to be held throughout the state change, it is not ideal to drop the lock before calling mhi_ep_resume_channels(). So to fix this issue, let's change the type of state_lock to mutex. This would also allow holding the lock throughout all state transitions thereby avoiding any potential race.

In those cases, the entire channel ring processing needs to be protected by chan->lock to prevent the race where the corresponding channel ring might be reset. While at it, let's also add a sanity check to make sure that the ring is started before processing it. Because, if the STOP/RESET command gets processed while mhi_ep_ch_ring_worker() waited for chan->lock, the ring would've been reset.

The patch will be merged to the char-misc-next branch sometime soon, after it passes testing, and the merge window is open. If you have any questions about this process, please let me know. From 1ddc7618294084fff8d673217a9479550990ee84 Mon Sep 17 00:00:00 2001 From: Manivannan Sadhasivam <manivannan.sadhasivam(a)linaro.org> Date: Mon, 23 Jan 2023 12:59:45 +0530 Subject: bus: mhi: ep: Change state_lock to mutex state_lock, the spinlock type is meant to protect race against concurrent MHI state transitions. In mhi_ep_set_m0_state(), while the state_lock is being held, the channels are resumed in mhi_ep_resume_channels() if the previous state was M3. This causes sleeping in atomic bug, since mhi_ep_resume_channels() use mutex internally. Since the state_lock is supposed to be held throughout the state change, it is not ideal to drop the lock before calling mhi_ep_resume_channels(). So to fix this issue, let's change the type of state_lock to mutex. This would also allow holding the lock throughout all state transitions thereby avoiding any potential race.
