similar to: ocfs2 quota support

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

Hello Sunil, attached is a patch which implements full quota support for ocfs2 tools. It's based against ocfs2-tools git's master branch. Would you please consider inclusion of the patch? Thanks.

Hi, In the ongoing drama surrounding this upgrade, I have encountered another issue that I am unable to currently resolve. mount.ocfs2 /dev/sdb1 /mnt mount.ocfs2: Stale NFS file handle while mounting /dev/sdb1 on /mnt. Check 'dmesg' for more information on this error. dmesg: (3701,1):ocfs2_populate_inode:240 ERROR: file entry generation does not match superblock!

It would be nice to know how often we get checksum failures. Even better, how many of them we can fix with the single bit ecc. So, we add a statistics structure. The structure can be installed into debugfs wherever the user wants. For ocfs2, we'll put it in the superblock-specific debugfs directory and pass it down from our higher-level functions. The stats are only registered with

Jan, since i can not cc you mail address when filing a bug on oss bugzilla,just paste the bug description here. Testing env, Kernel version:latest linus's mainline 2.6.27 Testing Nodes:test5/6 Description: Jan,i used your provided quota tools,now it works for me:),currently,i'm doing a sanity check for the quota on ocfs2. Found a strange thing when comparing with the ext3,the quota

ocfs2_quota_write needs to release the lock if it fails to read quota block. So use "goto out" instead of "return err".

Hello, the following series of patches fixes some issues with OCFS2 quotas. The first patch modifies VFS quota locking, the next patch uses the fact to simplify OCFS2 quota locking and solves a few deadlock issues. The third and the fourth patches fix another possible deadlocks in OCFS2 quota code and the last patch is a minor cleanup. Honza

Hi I have an ocfs2 volume (1.4.1) on lvm2, which is made available on 2 nodes via dual primary drbd that is on it. I wanted to backup my volume, so naturally I made a snapshot of it via the lvm2, and tried to mount it for backing up. However, I got the following error in dmesg : [319981.478168] (23483,0):ocfs2_fill_super:700 ERROR: Unable to create per-mount debugfs root. I then searched

Hi, I am little puzzled. I looked through the mailing list archive and some other sources but doesn't seem like anything anyone encountered. I have two systems with attached HP SAN. I'm using SLES 10.1 with multipath-tools. When trying to mount OCFS2 device I get this: SERVER:/ # mount.ocfs2 /dev/mapper/mpath0 /mnt/temp/ mount.ocfs2: Invalid argument while mounting

Hi Jan, I am now reading quota support in ocfs2 and have some qs. Wish you can help me clarify it. Thanks. ocfs2_quota_write: In the comment, you said that "we know the transaction is already started", so it should be called within a transaction. But in this function, we call ocfs2_extend_no_holes and ocfs2_simple_size_update which will start another transaction. So we can survive

Hi I'd like to know if OCFS2 1.4 on RHEL5 with the REDHAT latest kernel supports disk quotas, the xattr and acl. I could have done something wrong but only the acl seem to work. Apparently instead on FC12, where support is enabled in the kernel itself OCFS grep / boot / config * CONFIG_OCFS2_FS = m CONFIG_OCFS2_FS_O2CB = m CONFIG_OCFS2_FS_USERSPACE_CLUSTER = m # CONFIG_OCFS2_FS_STATS is

In commit ea455f8ab68338ba69f5d3362b342c115bea8e13, we move the dentry lock put process into ocfs2_wq. This is OK for most case, but as for umount, it lead to at least 2 bugs. See http://oss.oracle.com/bugzilla/show_bug.cgi?id=1133 and http://oss.oracle.com/bugzilla/show_bug.cgi?id=1135. And it happens easily if we have opened a lot of inodes. For 1135, the reason is that during umount will call
