* hfsplus: fix failed mount handlingChristoph Hellwig2011-02-031-45/+61
| | | | | | | | | | | Currently the error handling in hfsplus_fill_super is a mess, and can lead to accessing fields in the superblock that haven't been even set up yet. Fix this by making sure we do not set up sb->s_root until we have the mount fully set up, and before that do proper step by step unwinding instead of using hfsplus_put_super as a big hammer.

| * NFS: NFSv4 readdir loses entriesChuck Lever2011-01-281-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On recent 2.6.38-rc kernels, connectathon basic test 6 fails on NFSv4 mounts of OpenSolaris with something like: > ./test6: readdir > ./test6: (/mnt/klimt/matisse.test) didn't read expected 'file.12' dir entry, pass 0 > ./test6: (/mnt/klimt/matisse.test) didn't read expected 'file.82' dir entry, pass 0 > ./test6: (/mnt/klimt/matisse.test) didn't read expected 'file.164' dir entry, pass 0 > ./test6: (/mnt/klimt/matisse.test) Test failed with 3 errors > basic tests failed > Tests failed, leaving /mnt/klimt mounted > [cel@matisse cthon04]$ I narrowed the problem down to nfs4_decode_dirent() reporting that the decode buffer had overflowed while decoding the entries for those missing files. verify_attr_len() assumes both it's pointer arguments reside on the same page. When these arguments point to locations on two different pages, verify_attr_len() can report false errors. This can happen now that a large NFSv4 readdir result can span pages. We have reasonably good checking in nfs4_decode_dirent() anyway, so it should be safe to simply remove the extra checking. At a guess, this was introduced by commit 6650239a, "NFS: Don't use vm_map_ram() in readdir".

| * NFS: Micro-optimize nfs4_decode_dirent()Chuck Lever2011-01-281-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make the decoding of NFSv4 directory entries slightly more efficient by: 1. Avoiding unnecessary byte swapping when checking XDR booleans, and 2. Not bumping "p" when its value will be immediately replaced by xdr_inline_decode() This commit makes nfs4_decode_dirent() consistent with similar logic in the other two decode_dirent() functions.

[ BUG output redacted ] When done searching, the for_each_host loop in next_host_state() falls through and returns the final host on the host chain without bumping it's reference count. Since the host's ref count is only one at that point, releasing the host in nlm_host_rebooted() attempts to destroy the host prematurely, and therefore hits a BUG(). Likely, the original intent of the for_each_host behavior in next_host_state() was to handle the case when the host chain is empty. Searching the chain and finding no suitable host to return needs to be handled as well. Defensively restructure next_host_state() always to return NULL when the loop falls through.

| * NFS: Prevent memory allocation failure in nfsacl_encode()Chuck Lever2011-01-254-13/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | nfsacl_encode() allocates memory in certain cases. This of course is not guaranteed to work. Since commit 9f06c719 "SUNRPC: New xdr_streams XDR encoder API", the kernel's XDR encoders can't return a result indicating possibly a failure, so a memory allocation failure in nfsacl_encode() has become fatal (ie, the XDR code Oopses) in some cases. However, the allocated memory is a tiny fixed amount, on the order of 40-50 bytes. We can easily use a stack-allocated buffer for this, with only a wee bit of nose-holding.

To address this, prevent the NFS direct I/O engine from completing async iocbs when the forward path returns an error without starting any I/O. This fix appears to survive ^C during both "xfstest no. 208" and "fsx -Z." It's likely this bug has existed for a very long while, as we are seeing very similar symptoms in OEL 5. Copying stable.

Adding the extent into the ifork with br_startblock=0 can lead to the extent being copied into the btree by xfs_bmap_extent_to_btree if we happen to convert from extents format to btree format before updating br_startblock with the correct value. The unexpected addition of this delay extent to the btree can cause subsequent XFS_WANT_CORRUPTED_GOTO filesystem shutdown in several xfs_bmap_add_extent_delay_real cases where we are converting a delay extent to real and unexpectedly find an extent already inserted. For example: 911 case BMAP_LEFT_FILLING: 912 /* 913 * Filling in the first part of a previous delayed allocation. 914 * The left neighbor is not contiguous. 915 */ 916 trace_xfs_bmap_pre_update(ip, idx, state, _THIS_IP_); 917 xfs_bmbt_set_startoff(ep, new_endoff); 918 temp = PREV.br_blockcount - new->br_blockcount; 919 xfs_bmbt_set_blockcount(ep, temp); 920 xfs_iext_insert(ip, idx, 1, new, state); 921 ip->i_df.if_lastex = idx; 922 ip->i_d.di_nextents++; 923 if (cur == NULL) 924 rval = XFS_ILOG_CORE | XFS_ILOG_DEXT; 925 else { 926 rval = XFS_ILOG_CORE; 927 if ((error = xfs_bmbt_lookup_eq(cur, new->br_startoff, 928 new->br_startblock, new->br_blockcount, 929 &i))) 930 goto done; 931 XFS_WANT_CORRUPTED_GOTO(i == 0, done); With the bogus extent in the btree we shutdown the filesystem at 931. The conversion from extents to btree format happens when the number of extents in the inode increases above ip->i_df.if_ext_max. xfs_bmap_extent_to_btree copies extents from the ifork into the btree, ignoring all delalloc extents which are denoted by br_startblock having some value of nullstartblock.

This means that the alignment process can push the range to be allocated outside the bounds of the AG, resulting in assert failures or corrupted bmbt records. Similarly, if the extsize is larger than the maximum extent size supported, the alignment process will produce extents that are too large to fit into the bmbt records, resulting in a different type of assert/corruption failure. Fix this by limiting extsize at the time іt is set firstly to be less than MAXEXTLEN, then to be a maximum of half the size of the AGs in the filesystem for non-realtime inodes. Realtime inodes do not allocate out of AGs, so don't have to be restricted by the size of AGs.

Fix this by ensuring that we allow for space that extent size alignment requires (up to 2 * (extsize -1) blocks as we have to handle both head and tail alignment) when limiting the maximum size of the extent.

We should stop when we find the first AG with a maximum possible allocation size. This causes excessive CPU usage when there are lots of AGs. The same problem occurs when doing preallocation of a range larger than an AG. Fix the problem by limiting real allocation lengths to the maximum that an AG can support. This means if we have empty AGs, we'll stop the search at the first of them. If there are no empty AGs, we'll still scan them all, but that is a different problem....

This means that the EFI item is never freed if it was in the push being cancelled. The problem is specific to delayed logging, but has uncovered a couple of problems with the handling of IOP_UNPIN(remove). Firstly, we cannot safely call xfs_trans_del_item() from IOP_UNPIN() in the CIL commit failure path or the iclog write failure path because for delayed loging we have no transaction context. Hence we must only call xfs_trans_del_item() if the log item being unpinned has an active log item descriptor. Secondly, xfs_trans_uncommit() does not handle log item descriptor freeing during the traversal of log items on a transaction. It can reference a freed log item descriptor when unpinning an EFI item. Hence it needs to use a safe list traversal method to allow items to be removed from the transaction during IOP_UNPIN().

Update the doorbell-related defines to produce the entire doorbell value from a single macro. Document the doorbell format in a comment.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dev_dbg() is used to print ordinary transfer messages in xhci-ring.c. System log messages will be flushed if CONFIG_USB_DEBUG is set. Replace the dev_dbg() with xhci_dbg().

However, if the ring is wrapped and cycle bit is toggled to zero, then giveback_first_trb() will be of no effect. In this case, set the cycle bit of start_trb to 1 at the beginning and clear it in giveback_first_trb().
