2006-09-08[PATCH] NFS: large non-page-aligned direct I/O clobbers memoryTrond Myklebust3-69/+42
The logic in nfs_direct_read_schedule and nfs_direct_write_schedule can allow data->npages to be one larger than rpages. This causes a page pointer to be written beyond the end of the pagevec in nfs_read_data (or nfs_write_data). Fix this by making nfs_(read|write)_alloc() calculate the size of the pagevec array, and initialise data->npages. Also get rid of the redundant argument to nfs_commit_alloc().

It ends up returning -EIO. Here is the patch to fix it. If we really want to be paranoid, we can allow return values 0 (HOLE), 1 (we asked for one block) and return -EIO for more than 1 block. But I really don't see a reason for doing it - all we need is the block# here. (doesn't matter how many blocks are mapped). ext3_get_blocks_handle() returns number of blocks it mapped. It returns 0 in case of HOLE. ext3_getblk() should handle HOLE properly (currently its dumping warning stack and returning -EIO).

2006-08-27[PATCH] ufs: truncate correctionEvgeniy Dushistov1-52/+25
1) When we allocated last fragment in ufs_truncate, we read page, check if block mapped to address, and if not trying to allocate it. This is wrong behaviour, fragment may be NOT allocated, but mapped, this happened because of "block map" function not checked allocated fragment or not, it just take address of the first fragment in the block, add offset of fragment and return result, this is correct behaviour in almost all situation except call from ufs_truncate. 2) Almost all implementation of UFS, which I can investigate have such "defect": if you have full disk, and try truncate file, for example 3GB to 2MB, and have hole in this region, truncate return -ENOSPC. I tried evade from this problem, but "block allocation" algorithm is tied to right value of i_lastfrag, and fix of this corner case may slow down of ordinaries scenarios, so this patch makes behavior of "truncate" operations similar to what other UFS implementations do.

2006-08-27[PATCH] ufs: write to hole in big fileEvgeniy Dushistov1-14/+21
On UFS, this scenario: open(O_TRUNC) lseek(1024 * 1024 * 80) write("A") lseek(1024 * 2) write("A") may cause access to invalid address. This happened because of "goal" is calculated in wrong way in block allocation path, as I see this problem exists also in 2.4. We use construction like this i_data[lastfrag], i_data array of pointers to direct blocks, indirect and so on, it has ceratain size ~20 elements, and lastfrag may have value for example 40000. Also this patch fixes related to handling such scenario issues, wrong zeroing metadata, in case of block(not fragment) allocation, and wrong goal calculation, when we allocate block Signed-off-by: Evgeniy Dushistov <dushistov@mail.ru> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-08-27[PATCH] ext3 filesystem bogus ENOSPC with reservation fixMingming Cao1-3/+3
To handle the earlier bogus ENOSPC error caused by filesystem full of block reservation, current code falls back to non block reservation, starts to allocate block(s) from the goal allocation block group as if there is no block reservation. Current code needs to re-load the corresponding block group descriptor for the initial goal block group in this case. The patch fixes this.

Currently, the access() call will return incorrect information on NFS if there exists an ACL that grants execute access to the user on a regular file. The reason the information is incorrect is that the VFS overrides this execute access in open_exec() by checking (inode->i_mode & 0111).

2006-08-24NFS: Check lengths more thoroughly in NFS4 readdir XDR decodeDavid Howells1-10/+11
Check the bounds of length specifiers more thoroughly in the XDR decoding of NFS4 readdir reply data. Currently, if the server returns a bitmap or attr length that causes the current decode point pointer to wrap, this could go undetected (consider a small "negative" length on a 32-bit machine). Also add a check into the main XDR decode handler to make sure that the amount of data is a multiple of four bytes (as specified by RFC-1014). This makes sure that we can do u32* pointer subtraction in the NFS client without risking an undefined result (the result is undefined if the pointers are not correctly aligned with respect to one another).

2006-08-24VFS: add lookup hint for network file systemsASANO Masahiro1-0/+2
I'm trying to speeding up mkdir(2) for network file systems. A typical mkdir(2) calls two inode_operations: lookup and mkdir. The lookup operation would fail with ENOENT in common case. I think it is unnecessary because the subsequent mkdir operation can check it. In case of creat(2), lookup operation is called with the LOOKUP_CREATE flag, so individual filesystem can omit real lookup. e.g. nfs_lookup(). Here is a sample patch which uses LOOKUP_CREATE and O_EXCL on mkdir, symlink and mknod. This uses the gadget for creat(2).

The following patch to udf_alloc_inode() should take care of both (and other similar) cases, but I've only tested it with udf_lookup().

2006-08-10[XFS] Fix xfs_free_extent related NULL pointer dereference.Nathan Scott1-49/+54
We recently fixed an out-of-space deadlock in XFS, and part of that fix involved the addition of the XFS_ALLOC_FLAG_FREEING flag to some of the space allocator calls to indicate they're freeing space, not allocating it. There was a missed xfs_alloc_fix_freelist condition test that did not correctly test "flags". The same test would also test an uninitialised structure field (args->userdata) and depending on its value either would or would not return early with a critical buffer pointer set to NULL. This fixes that up, adds asserts to several places to catch future botches of this nature, and skips sections of xfs_alloc_fix_freelist that are irrelevent for the space-freeing case.
