2008-04-18[XFS] Don't block pdflush when writing back inodesDavid Chinner1-1/+2
When pdflush is writing back inodes, it can get stuck on inode cluster buffers that are currently under I/O. This occurs when we write data to multiple inodes in the same inode cluster at the same time. Effectively, delayed allocation marks the inode dirty during the data writeback. Hence if the inode cluster was flushed during the writeback of the first inode, the writeback of the second inode will block waiting for the inode cluster write to complete before writing it again for the newly dirtied inode. Basically, we want to avoid this from happening so we don't block pdflush and slow down all of writeback. Hence we introduce a non-blocking async inode flush flag that pdflush uses. If this flag is set, we use non-blocking operations (e.g. try locks) whereever we can to avoid blocking or extra I/O being issued.

2008-02-07[XFS] Remove CFORK macros and use code directly in IFORK and DFORK macros.Christoph Hellwig1-2/+2
Currently XFS_IFORK_* and XFS_DFORK* are implemented by means of XFS_CFORK* macros. But given that XFS_IFORK_* operates on an xfs_inode that embedds and xfs_icdinode_core and XFS_DFORK_* operates on an xfs_dinode that embedds a xfs_dinode_core one will have to do endian swapping while the other doesn't. Instead of having the current mess with the CFORK macros that have byteswapping and non-byteswapping version (which are inconsistantly named while we're at it) just define each family of the macros to stand by itself and simplify the whole matter. A few direct references to the CFORK variants were cleaned up to use IFORK or DFORK to make this possible.

2008-02-07[XFS] Make xfs_bulkstat() to report unlinked but referenced inodesVlad Apostolov1-2/+2
We need xfs_bulkstat() to report inode stat for inodes with link count zero but reference count non zero. The fix here: http://oss.sgi.com/archives/xfs/2007-09/msg00266.html changed this behavior and made xfs_bulkstat() to filter all unlinked inodes including those that are not destroyed yet but held by reference. The attached patch returns back to the original behavior by marking the on-disk inode buffer "dirty" when di_mode is cleared (at that time both inode link and reference counter are zero).

2007-12-10[XFS] 971064 Various fixups for xfs_bulkstat().Lachlan McIlroy1-14/+29
- sanity check for NULL user buffer in xfs_ioc_bulkstat[_compat]() - remove the special case for XFS_IOC_FSBULKSTAT with count == 1. This special case causes bulkstat to fail because the special case uses xfs_bulkstat_single() instead of xfs_bulkstat() and the two functions have different semantics. xfs_bulkstat() will return the next inode after the one supplied while skipping internal inodes (ie quota inodes). xfs_bulkstate_single() will only lookup the inode supplied and return an error if it is an internal inode. - in xfs_bulkstat(), need to initialise 'lastino' to the inode supplied so in cases were we return without examining any inodes the scan wont restart back at zero. - sanity check for valid *ubcountp values. Cannot sanity check for valid ubuffer here because some users of xfs_bulkstat() don't supply a buffer. - checks against 'ubleft' (the space left in the user's buffer) should be against 'statstruct_size' which is the supplied minimum object size. The mixture of checks against statstruct_size and 0 was one of the reasons we were skipping inodes. - if the formatter function returns BULKSTAT_RV_NOTHING and an error and the error is not ENOENT or EINVAL then we need to abort the scan. ENOENT is for inodes that are no longer valid and we just skip them. EINVAL is returned if we try to lookup an internal inode so we skip them too. For a DMF scan if the inode and DMF attribute cannot fit into the space left in the user's buffer it would return ERANGE. We didn't handle this error and skipped the inode. We would continue to skip inodes until one fitted into the user's buffer or we completed the scan. - put back the recalculation of agino (that got removed with the last fix) at the end of the while loop. This is because the code at the start of the loop expects agino to be the last inode examined if it is non-zero. - if we found some inodes but then encountered an error, return success this time and the error next time. If the formatter aborted with ENOMEM we will now return this error but only if we couldn't read any inodes. Previously if we encountered ENOMEM without reading any inodes we returned a zero count and no error which falsely indicated the scan was complete.

2007-10-16[XFS] This fix prevents bulkstat from spinning in an infinite loop.Lachlan McIlroy1-6/+9
Here 'agino' increments through the inodes in an allocation group. At the end of the innermost 'for' loop it will hold the value of the next inode to look at (ie the first inode in the next cluster/chunk). Assigning 'lastino' to 'agino' resets it to the last inode in the last inode cluster we just looked at. This causes us to look up the very same cluster and examine all the inodes all over again, and again, and again... We also want to set 'lastino' for the cases when we're not interested in the inode so that the next call to bulkstat won't re-examine the same uninteresting inodes.

2007-10-16[XFS] get_bulkall() could return incorrect inode stateVlad Apostolov1-1/+9
In the following scenario xfs_bulkstat() returns incorrect stale inode state: 1. File_A is created and its inode synced to disk. 2. File_A is unlinked and doesn't exist anymore. 3. Filesystem sync is invoked. 4. File_B is created. File_B happens to reclaim File_A's inode. 5. xfs_bulkstat() is called and detects File_B but reports the incorrect File_A inode state. Explanation for the incorrect inode state is that inodes are not immediately synced on file create for performance reasons. This leaves the on-disk inode buffer uninitialized (or with old state from a previous generation inode) and this is what xfs_bulkstat() would report. The patch marks the on-disk inode buffer "dirty" on unlink. When the inode is reclaimed (by a new file create), xfs_bulkstat() would filter this inode by the "dirty" mark. Once the inode is flushed to disk, the on-disk buffer "dirty" mark is automatically removed and a following xfs_bulkstat() would return the correct inode state. Marking the on-disk inode buffer "dirty" on unlink is achieved by setting the on-disk di_nlink field to 0. Note that the in-core di_nlink has already been set to 0 and a corresponding transaction logged by xfs_droplink(). This is an exception from the rule that any on-disk inode buffer changes has to be followed by a disk write (inode flush). Synchronizing the in-core to on-disk di_nlink values in advance (before the actual inode flush to disk) should be fine in this case because the inode is already unlinked and it would never change its di_nlink again for this inode generation.

2007-10-15[XFS] dinode endianess annotationsChristoph Hellwig1-28/+27
Biggest bit is duplicating the dinode structure so we have one annotated for native endianess and one for disk endianess. The other significant change is that xfs_xlate_dinode_core is split into one helper per direction to allow for proper annotations, everything else is trivial. As a sidenode splitting out the incore dinode means we can move it into xfs_inode.h in a later patch and severely improving on the include hell in xfs.

* 32bit struct xfs_fsop_bulkreq has different size and layout of members, no matter the alignment. Move the code out of the #else branch (why was it there in the first place?). Define _32 variants of the ioctl constants. * 32bit struct xfs_bstat is different because of time_t and on i386 because of different padding. Make xfs_bulkstat_one() accept a custom "output formatter" in the private_data argument which takes care of the xfs_bulkstat_one_compat() that takes care of the different layout in the compat case. * i386 struct xfs_inogrp has different padding.

The previous attempts to fix the linux inode use-after-free in xfs_iunpin simply made the problem harder to hit. We actually need complete exclusion between xfs_reclaim and xfs_iunpin, as well as ensuring that the i_flags are consistent during both of these functions.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.
