[PATCH openEuler-1.0-LTS] ocfs2: fix data corruption by fallocate
by Yifan Qiao 19 Mar '24

19 Mar '24

From: Junxiao Bi <junxiao.bi(a)oracle.com> stable inclusion from stable-5.10.43 commit c8d5faee46242c3f33b8a71a4d7d52214785bfcc category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9909V CVE: CVE-2021-47114 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- commit 6bba4471f0cc1296fe3c2089b9e52442d3074b2e upstream. When fallocate punches holes out of inode size, if original isize is in the middle of last cluster, then the part from isize to the end of the cluster will be zeroed with buffer write, at that time isize is not yet updated to match the new size, if writeback is kicked in, it will invoke ocfs2_writepage()->block_write_full_page() where the pages out of inode size will be dropped. That will cause file corruption. Fix this by zero out eof blocks when extending the inode size. Running the following command with qemu-image 4.2.1 can get a corrupted coverted image file easily. qemu-img convert -p -t none -T none -f qcow2 $qcow_image \ -O qcow2 -o compat=1.1 $qcow_image.conv The usage of fallocate in qemu is like this, it first punches holes out of inode size, then extend the inode size. fallocate(11, FALLOC_FL_KEEP_SIZE|FALLOC_FL_PUNCH_HOLE, 2276196352, 65536) = 0 fallocate(11, 0, 2276196352, 65536) = 0 v1: https://www.spinics.net/lists/linux-fsdevel/msg193999.html v2: https://lore.kernel.org/linux-fsdevel/20210525093034.GB4112@quack2.suse.cz/… Link: https://lkml.kernel.org/r/20210528210648.9124-1-junxiao.bi@oracle.com Signed-off-by: Junxiao Bi <junxiao.bi(a)oracle.com> Reviewed-by: Joseph Qi <joseph.qi(a)linux.alibaba.com> Cc: Jan Kara <jack(a)suse.cz> Cc: Mark Fasheh <mark(a)fasheh.com> Cc: Joel Becker <jlbec(a)evilplan.org> Cc: Changwei Ge <gechangwei(a)live.cn> Cc: Gang He <ghe(a)suse.com> Cc: Jun Piao <piaojun(a)huawei.com> Cc: <stable(a)vger.kernel.org> Signed-off-by: Andrew Morton <akpm(a)linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds(a)linux-foundation.org> Signed-off-by: Yifan Qiao <qiaoyifan4(a)huawei.com> --- fs/ocfs2/file.c | 55 ++++++++++++++++++++++++++++++++++++++++++++----- 1 file changed, 50 insertions(+), 5 deletions(-) diff --git a/fs/ocfs2/file.c b/fs/ocfs2/file.c index a3e077fcfeb9..3e699c4a2e37 100644 --- a/fs/ocfs2/file.c +++ b/fs/ocfs2/file.c @@ -1859,6 +1859,45 @@ int ocfs2_remove_inode_range(struct inode *inode, return ret; } +/* + * zero out partial blocks of one cluster. + * + * start: file offset where zero starts, will be made upper block aligned. + * len: it will be trimmed to the end of current cluster if "start + len" + * is bigger than it. + */ +static int ocfs2_zeroout_partial_cluster(struct inode *inode, + u64 start, u64 len) +{ + int ret; + u64 start_block, end_block, nr_blocks; + u64 p_block, offset; + u32 cluster, p_cluster, nr_clusters; + struct super_block *sb = inode->i_sb; + u64 end = ocfs2_align_bytes_to_clusters(sb, start); + + if (start + len < end) + end = start + len; + + start_block = ocfs2_blocks_for_bytes(sb, start); + end_block = ocfs2_blocks_for_bytes(sb, end); + nr_blocks = end_block - start_block; + if (!nr_blocks) + return 0; + + cluster = ocfs2_bytes_to_clusters(sb, start); + ret = ocfs2_get_clusters(inode, cluster, &p_cluster, + &nr_clusters, NULL); + if (ret) + return ret; + if (!p_cluster) + return 0; + + offset = start_block - ocfs2_clusters_to_blocks(sb, cluster); + p_block = ocfs2_clusters_to_blocks(sb, p_cluster) + offset; + return sb_issue_zeroout(sb, p_block, nr_blocks, GFP_NOFS); +} + /* * Parts of this function taken from xfs_change_file_space() */ @@ -1869,7 +1908,7 @@ static int __ocfs2_change_file_space(struct file *file, struct inode *inode, { int ret; s64 llen; - loff_t size; + loff_t size, orig_isize; struct ocfs2_super *osb = OCFS2_SB(inode->i_sb); struct buffer_head *di_bh = NULL; handle_t *handle; @@ -1900,6 +1939,7 @@ static int __ocfs2_change_file_space(struct file *file, struct inode *inode, goto out_inode_unlock; } + orig_isize = i_size_read(inode); switch (sr->l_whence) { case 0: /*SEEK_SET*/ break; @@ -1907,7 +1947,7 @@ static int __ocfs2_change_file_space(struct file *file, struct inode *inode, sr->l_start += f_pos; break; case 2: /*SEEK_END*/ - sr->l_start += i_size_read(inode); + sr->l_start += orig_isize; break; default: ret = -EINVAL; @@ -1961,6 +2001,14 @@ static int __ocfs2_change_file_space(struct file *file, struct inode *inode, default: ret = -EINVAL; } + + /* zeroout eof blocks in the cluster. */ + if (!ret && change_size && orig_isize < size) { + ret = ocfs2_zeroout_partial_cluster(inode, orig_isize, + size - orig_isize); + if (!ret) + i_size_write(inode, size); + } up_write(&OCFS2_I(inode)->ip_alloc_sem); if (ret) { mlog_errno(ret); @@ -1977,9 +2025,6 @@ static int __ocfs2_change_file_space(struct file *file, struct inode *inode, goto out_inode_unlock; } - if (change_size && i_size_read(inode) < size) - i_size_write(inode, size); - inode->i_ctime = inode->i_mtime = current_time(inode); ret = ocfs2_mark_inode_dirty(handle, inode, di_bh); if (ret < 0) -- 2.39.2

[PATCH OLK-5.10] KVM: s390: fix setting of fpc register
by Ze Zuo 18 Mar '24

18 Mar '24

From: Heiko Carstens <hca(a)linux.ibm.com> stable inclusion from stable-v5.10.210 commit 150a3a3871490e8c454ffbac2e60abeafcecff99 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I96GPO CVE: CVE-2023-52597 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit b988b1bb0053c0dcd26187d29ef07566a565cf55 ] kvm_arch_vcpu_ioctl_set_fpu() allows to set the floating point control (fpc) register of a guest cpu. The new value is tested for validity by temporarily loading it into the fpc register. This may lead to corruption of the fpc register of the host process: if an interrupt happens while the value is temporarily loaded into the fpc register, and within interrupt context floating point or vector registers are used, the current fp/vx registers are saved with save_fpu_regs() assuming they belong to user space and will be loaded into fp/vx registers when returning to user space. test_fp_ctl() restores the original user space / host process fpc register value, however it will be discarded, when returning to user space. In result the host process will incorrectly continue to run with the value that was supposed to be used for a guest cpu. Fix this by simply removing the test. There is another test right before the SIE context is entered which will handles invalid values. This results in a change of behaviour: invalid values will now be accepted instead of that the ioctl fails with -EINVAL. This seems to be acceptable, given that this interface is most likely not used anymore, and this is in addition the same behaviour implemented with the memory mapped interface (replace invalid values with zero) - see sync_regs() in kvm-s390.c.

[PATCH OLK-5.10 v2] iomap: add support to track dirty state of sub pages
by Yu Kuai 18 Mar '24

18 Mar '24

hulk inclusion category: performance bugzilla: https://gitee.com/openeuler/kernel/issues/I93TU0 CVE: NA ------------------------------------------ commit 9dc55f1389f9 ("iomap: add support for sub-pagesize buffered I/O without buffer heads") replace the per-block structure buffer_head with the per-page structure iomap_page. However, iomap_page can't track the dirty state of sub pages, which will cause performance issue since sub pages will be writeback even if they are not dirty. For example, if block size is 4k and page size is 64k: dd if=/dev/zero of=testfile bs=4k count=16 oflag=sync With buffer_head implementation, the above dd cmd will writeback 4k in each round. However, with iomap_page implementation, the range of writeback in each round is from the start of the page to the end offset we just wrote. Thus add support to track dirty state in iomap_page. test environment: platform: arm64 pagesize: 64k blocksize: 4k test case: dd if=/dev/zero of=/mnt/testfile bs=1M count=128 fio --ioengine=sync --rw=randwrite --iodepth=64 --name=test \ --filename=/mnt/testfile --bs=4k --fsync=1 The test result is: xfs with patch: WRITE: bw=4609KiB/s (4720kB/s) xfs without patch WRITE: bw=2714KiB/s (2780kB/s) ext4: WRITE: bw=3840KiB/s (3932kB/s) Signed-off-by: Yu Kuai <yukuai3(a)huawei.com> --- Changes in v2: - remove changes to iomap_page_mkwrite_actor(). fs/iomap/buffered-io.c | 83 ++++++++++++++++++++++++++++++++++-------- 1 file changed, 67 insertions(+), 16 deletions(-) diff --git a/fs/iomap/buffered-io.c b/fs/iomap/buffered-io.c index d9092aa5c3fb..25448d5827d2 100644 --- a/fs/iomap/buffered-io.c +++ b/fs/iomap/buffered-io.c @@ -25,13 +25,13 @@ /* * Structure allocated for each page or THP when block size < page size - * to track sub-page uptodate status and I/O completions. + * to track sub-page uptodate and dirty status and I/O completions. */ struct iomap_page { atomic_t read_bytes_pending;

[PATCH OLK-5.10] bus: mhi: host: Add alignment check for event ring read pointer
by Cai Xinchen 18 Mar '24

18 Mar '24

From: Krishna chaitanya chundru <quic_krichai(a)quicinc.com> mainline inclusion from mainline-v6.8-rc1 commit eff9704f5332a13b08fbdbe0f84059c9e7051d5f category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I99JF1 CVE: CVE-2023-52494 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… ------------------------------------------------------ Though we do check the event ring read pointer by "is_valid_ring_ptr" to make sure it is in the buffer range, but there is another risk the pointer may be not aligned. Since we are expecting event ring elements are 128 bits(struct mhi_ring_element) aligned, an unaligned read pointer could lead to multiple issues like DoS or ring buffer memory corruption.

[PATCH OLK-5.10] bus: mhi: host: Add alignment check for event ring read pointer

From: Krishna chaitanya chundru <quic_krichai(a)quicinc.com> mainline inclusion from mainline-v6.8-rc1 commit eff9704f5332a13b08fbdbe0f84059c9e7051d5f category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I96S0P CVE: CVE-2023-52494 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… ------------------------------------------------------ Though we do check the event ring read pointer by "is_valid_ring_ptr" to make sure it is in the buffer range, but there is another risk the pointer may be not aligned. Since we are expecting event ring elements are 128 bits(struct mhi_ring_element) aligned, an unaligned read pointer could lead to multiple issues like DoS or ring buffer memory corruption. So add a alignment check for event ring read pointer.

[PATCH OLK-5.10] bus: mhi: host: Add alignment check for event ring read pointer

From: Krishna chaitanya chundru <quic_krichai(a)quicinc.com> mainline inclusion from mainline-v6.8-rc1 commit eff9704f5332a13b08fbdbe0f84059c9e7051d5f category: bugfix bugzilla: 189679 CVE: CVE-2023-52494 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… ------------------------------------------------------ Though we do check the event ring read pointer by "is_valid_ring_ptr" to make sure it is in the buffer range, but there is another risk the pointer may be not aligned. Since we are expecting event ring elements are 128 bits(struct mhi_ring_element) aligned, an unaligned read pointer could lead to multiple issues like DoS or ring buffer memory corruption. So add a alignment check for event ring read pointer.

[PATCH OLK-5.10] bus: mhi: host: Add alignment check for event ring read pointer
by Cai Xinchen 18 Mar '24

18 Mar '24

From: Krishna chaitanya chundru <quic_krichai(a)quicinc.com> mainline inclusion from mainline-v6.8-rc1 commit eff9704f5332a13b08fbdbe0f84059c9e7051d5f category: bugfix bugzilla: 189679 CVE: CVE-2023-52494 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… ------------------------------------------------------ Though we do check the event ring read pointer by "is_valid_ring_ptr" to make sure it is in the buffer range, but there is another risk the pointer may be not aligned. Since we are expecting event ring elements are 128 bits(struct mhi_ring_element) aligned, an unaligned read pointer could lead to multiple issues like DoS or ring buffer memory corruption. So add a alignment check for event ring read pointer.

[PATCH openEuler-1.0-LTS] nfsd: fix use-after-free due to delegation race
by Li Lingfeng 18 Mar '24

18 Mar '24

From: "J. Bruce Fields" <bfields(a)redhat.com> mainline inclusion from mainline-v5.16-rc5 commit 548ec0805c399c65ed66c6641be467f717833ab5 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I99EU2 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- A delegation break could arrive as soon as we've called vfs_setlease. A delegation break runs a callback which immediately (in nfsd4_cb_recall_prepare) adds the delegation to del_recall_lru. If we then exit nfs4_set_delegation without hashing the delegation, it will be freed as soon as the callback is done with it, without ever being removed from del_recall_lru. Symptoms show up later as use-after-free or list corruption warnings, usually in the laundromat thread. I suspect aba2072f4523 "nfsd: grant read delegations to clients holding writes" made this bug easier to hit, but I looked as far back as v3.0 and it looks to me it already had the same problem. So I'm not sure where the bug was introduced; it may have been there from the beginning. Cc: stable(a)vger.kernel.org Signed-off-by: J.

[PATCH OLK-5.10] serial: sc16is7xx: convert from _raw_ to _noinc_ regmap functions for FIFO
by GONG, Ruiqi 18 Mar '24

18 Mar '24

From: Hugo Villeneuve <hvilleneuve(a)dimonoff.com> stable inclusion from stable-v6.1.76 commit 416b10d2817c94db86829fb92ad43ce7d002c573 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I96ZNC CVE: CVE-2023-52488 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit dbf4ab821804df071c8b566d9813083125e6d97b upstream. The SC16IS7XX IC supports a burst mode to access the FIFOs where the initial register address is sent ($00), followed by all the FIFO data without having to resend the register address each time. In this mode, the IC doesn't increment the register address for each R/W byte. The regmap_raw_read() and regmap_raw_write() are functions which can perform IO over multiple registers. They are currently used to read/write from/to the FIFO, and although they operate correctly in this burst mode on the SPI bus, they would corrupt the regmap cache if it was not disabled manually. The reason is that when the R/W size is more than 1 byte, these functions assume that the register address is incremented and handle the cache accordingly. Convert FIFO R/W functions to use the regmap _noinc_ versions in order to remove the manual cache control which was a workaround when using the _raw_ versions. FIFO registers are properly declared as volatile so cache will not be used/updated for FIFO accesses.

[PATCH openEuler-1.0-LTS] printk: avoid deadlock in panic
by Ye Weihua 18 Mar '24

18 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().
