2019-11-15xfs: fix attr leaf header freemap.size underflowBrian Foster
The leaf format xattr addition helper xfs_attr3_leaf_add_work() adjusts the block freemap in a couple places. The first update drops the size of the freemap that the caller had already selected to place the xattr name/value data. Before the function returns, it also checks whether the entries array has encroached on a freemap range by virtue of the new entry addition. This is necessary because the entries array grows from the start of the block (but end of the block header) towards the end of the block while the name/value data grows from the end of the block in the opposite direction. If the associated freemap is already empty, however, size is zero and the subtraction underflows the field and causes corruption. This is reproduced rarely by generic/070. The observed behavior is that a smaller sized freemap is aligned to the end of the entries list, several subsequent xattr additions land in larger freemaps and the entries list expands into the smaller freemap until it is fully consumed and then underflows. Note that it is not otherwise a corruption for the entries array to consume an empty freemap because the nameval list (i.e. the firstused pointer in the xattr header) starts beyond the end of the corrupted freemap. Update the freemap size modification to account for the fact that the freemap entry can be empty and thus stale. Signed-off-by: Brian Foster <bfoster@redhat.com> Reviewed-by: Darrick J.

2019-11-13xfs: avoid time_t in user apiArnd Bergmann
The ioctl definitions for XFS_IOC_SWAPEXT, XFS_IOC_FSBULKSTAT and XFS_IOC_FSBULKSTAT_SINGLE are part of libxfs and based on time_t. The definition for time_t differs between current kernels and coming 32-bit libc variants that define it as 64-bit. For most ioctls, that means the kernel has to be able to handle two different command codes based on the different structure sizes. The same solution could be applied for XFS_IOC_SWAPEXT, but it would not work for XFS_IOC_FSBULKSTAT and XFS_IOC_FSBULKSTAT_SINGLE because the structure with the time_t is passed through an indirect pointer, and the command number itself is based on struct xfs_fsop_bulkreq, which does not differ based on time_t. This means any solution that can be applied requires a change of the ABI definition in the xfs_fs.h header file, as well as doing the same change in any user application that contains a copy of this header. The usual solution would be to define a replacement structure and use conditional compilation for the ioctl command codes to use one or the other, such as #define XFS_IOC_FSBULKSTAT_OLD _IOWR('X', 101, struct xfs_fsop_bulkreq) #define XFS_IOC_FSBULKSTAT_NEW _IOWR('X', 129, struct xfs_fsop_bulkreq) #define XFS_IOC_FSBULKSTAT ((sizeof(time_t) == sizeof(__kernel_long_t)) ? \ XFS_IOC_FSBULKSTAT_OLD : XFS_IOC_FSBULKSTAT_NEW) After this, the kernel would be able to implement both XFS_IOC_FSBULKSTAT_OLD and XFS_IOC_FSBULKSTAT_NEW handlers on 32-bit architectures with the correct ABI for either definition of time_t. However, as long as two observations are true, a much simpler solution can be used: 1. xfsprogs is the only user space project that has a copy of this header 2. xfsprogs already has a replacement for all three affected ioctl commands, based on the xfs_bulkstat structure to pass 64-bit timestamps regardless of the architecture Based on those assumptions, changing xfs_bstime to use __kernel_long_t instead of time_t in both the kernel and in xfsprogs preserves the current ABI for any libc definition of time_t and solves the problem of passing 64-bit timestamps to 32-bit user space. If either of the two assumptions is invalid, more discussion is needed for coming up with a way to fix as much of the affected user space code as possible.

2019-11-13xfs: Fix deadlock between AGI and AGF when target_ip exists in xfs_rename()kaixuxia
When target_ip exists in xfs_rename(), the xfs_dir_replace() call may need to hold the AGF lock to allocate more blocks, and then invoking the xfs_droplink() call to hold AGI lock to drop target_ip onto the unlinked list, so we get the lock order AGF->AGI. This would break the ordering constraint on AGI and AGF locking - inode allocation locks the AGI, then can allocate a new extent for new inodes, locking the AGF after the AGI. In this patch we check whether the replace operation need more blocks firstly. If so, acquire the agi lock firstly to preserve locking order(AGI/AGF). Actually, the locking order problem only occurs when we are locking the AGI/AGF of the same AG. For multiple AGs the AGI lock will be released after the transaction committed.
