It's trivial to trigger a use-after-free bug in the ocfs2 quotas code using fstest generic/452. After a read-only remount, quotas are suspended and ocfs2_mem_dqinfo is freed through ->ocfs2_local_free_info(). When unmounting the filesystem, an UAF access to the oinfo will eventually cause a crash. BUG: KASAN: slab-use-after-free in timer_delete+0x54/0xc0 Read of size 8 at addr

Hi Andrew, There is an updated version v2, which describe more clearly about the case: https://lore.kernel.org/ocfs2-devel/e9fc4b2f-1fcc-7c31-f346-59eccff50f9b at linux.alibaba.com/T/#u Thanks, Joseph On 5/26/23 4:55 AM, Andrew Morton wrote: > The patch titled > Subject: ocfs2: fix use-after-free when unmounting read-only filesystem > has been added to the -mm mm-hotfixes-unstable

The patch titled Subject: ocfs2: fix use-after-free when unmounting read-only filesystem has been added to the -mm mm-hotfixes-unstable branch. Its filename is ocfs2-fix-use-after-free-when-unmounting-read-only-filesystem.patch This patch will shortly appear at

This patch implements functions and timer setup which handles periodic syncing of locally cached quota information to global quota file.

Thanks. As you can see from the above link, the email never hit ocfs2-devel and never

Now in ocfs2_local_free_info(), it returns 0 even if it actually fails. Though it doesn't cause any real problem since the only caller dquot_disable() ignores the return value, we'd better return correct as it is.

Hi, here is the second version of OCFS2 quota fixes with Joel's comments fixed. Also I've added a patch defining counts of credits for quota operations as Joel asked. Honza

Hi, I did some more in-depth testing of OCFS2 quota code, especially with ECC feature enabled and spotted some problems. First four patches fix them. I need the fifth patch to be able to mount OCFS2 filesystem with 2.6.31-rc3. The sixth patch fixes a potential problem when quota syncing interval is updated while the cluster is running (which is not possible currently). Joel, could you please

Hi, All, When mount ocfs2 with option usrquota and grpquota, we will see below message: (mount.ocfs2,9434,1):ocfs2_global_read_info:403 ERROR: status = 24 (mount.ocfs2,9434,3):ocfs2_global_read_info:403 ERROR: status = 24 But actually this should not be a error. In ocfs2_global_read_info, if read_quota() succeed, status is the size of the struct ocfs2_global_disk_dqinfo, only when it is not

use i_size_read() instead of accessing inode->i_size directly.

Hi, This is the second batch of Ocfs2 patches intended for the merge window. The 1st batch were sent out previously: http://lkml.org/lkml/2008/12/19/280 The bulk of this set is comprised of Jan Kara's patches to add quota support to Ocfs2. Many of the quota patches are to generic code, which I carried to make merging of the Ocfs2 support easier. All of the non-ocfs2 patches should have
