2007-04-04[PATCH] remove protection of LANANA-reserved majorsAndrew Morton1-2/+0
Revert all this. It can cause device-mapper to receive a different major from earlier kernels and it turns out that the Amanda backup program (via GNU tar, apparently) checks major numbers on files when performing incremental backups. Which is a bit broken of Amanda (or tar), but this feature isn't important enough to justify the churn.

2007-04-02[PATCH] revert "retries in ext3_prepare_write() violate ordering requirements"Andrew Morton1-75/+10
Revert e92a4d595b464c4aae64be39ca61a9ffe9c8b278. Dmitry points out "When we block_prepare_write() failed while ext3_prepare_write() we jump to "failure" label and call ext3_prepare_failure() witch search last mapped bh and invoke commit_write untill it. This is wrong!! because some bh from begining to the last mapped bh may be not uptodate. As a result we commit to disk not uptodate page content witch contains garbage from previous usage." and "Unexpected file size increasing." Call trace the same as it was in first issue but result is different. For example we have file with i_size is zero. we want write two blocks , but fs has only one free block. ->ext3_prepare_write(...from == 0, to == 2048) retry: ->block_prepare_write() == -ENOSPC# we failed but allocated one block here. ->ext3_prepare_failure() ->commit_write( from == 0, to == 1024) # after this i_size becomes 1024 :) if (ret == -ENOSPC && ext3_should_retry_alloc(inode->i_sb, &retries)) goto retry; Finally when all retries will be spended ext3_prepare_failure return -ENOSPC, but i_size was increased and later block trimm procedures can't help here. We don't appear to have the horsepower to fix these issues, so let's put things back the way they were for now.

Splice does not need to readpage to bring the page uptodate before writing to it, because prepare_write will take care of that for us.

2007-03-271/2 splice: dont stealNick Piggin1-63/+38
Stealing pages with splice is problematic because we cannot just insert an uptodate page into the pagecache and hope the filesystem can take care of it later. We also cannot just ClearPageUptodate, then hope prepare_write does not write anything into the page, because I don't think prepare_write gives that guarantee. Remove support for SPLICE_F_MOVE for now. If we really want to bring it back, we might be able to do so with a the new filesystem buffered write aops APIs I'm working on. If we really don't want to bring it back, then we should decide that sooner rather than later, and remove the flag and all the stealing infrastructure before anybody starts using it.

2007-03-16[PATCH] fix process crash caused by randomisation and 64k pagesJames Bottomley1-1/+1
This bug was seen on ppc64, but it could have occurred on any architecture with a page size of 64k or above. The problem is that in fs/binfmt_elf.c:randomize_stack_top() randomizes the stack to within 0x7ff pages. On 4k page machines, this is 8MB; on 64k page boxes, this is 128MB. The problem is that the new binary layout (selected in arch_pick_mmap_layout) places the mapping segment 128MB or the stack rlimit away from the top of the process memory, whichever is larger. If you chose an rlimit of less than 128MB (most defaults are in the 8Mb range) then you can end up having your entire stack randomized away. The fix is to make randomize_stack_top() only steal at most 8MB, which this patch does. However, I have to point out that even with this, your stack rlimit might not be exactly what you get if it's > 128MB, because you're still losing the random offset of up to 8MB. The true fix should be to leave an explicit gap for the randomization plus a buffer when determining mmap_base, but that would involve fixing all the architectures.

The current NFS client congestion logic is severly broken, it marks the backing device congested during each nfs_writepages() call but doesn't mirror this in nfs_writepage() which makes for deadlocks. Also it implements its own waitqueue. Replace this by a more regular congestion implementation that puts a cap on the number of active writeback pages and uses the bdi congestion waitqueue. Also always use an interruptible wait since it makes sense to be able to SIGKILL the process even for mounts without 'intr'.

2007-03-16[PATCH] fix rescan_partitions to return errors properlysuzuki1-1/+1
The only error code which comes from the partition checkers is -1, when they finds an EIO. As per the discussion, ENOMEM values were ignored, as they might scare the users. So, with the current code, we end up returning -1 and not EIO for the ioctl() calls. Which doesn't give any clue to the user of what went wrong.

2007-03-16[PATCH] smbfs: double free memory corruptionVasily Averin1-0/+1
smbfs allocates rq_trans2buffer to handle server's multi transaction2 response messages. As struct smb_request may be reused, rq_trans2buffer is freed before each new request. However if last servers's response is not multi but single trans2 message then new rq_trans2buffer is not allocated but last smb_rput still tries to free it again. To prevent this issue rq_trans2buffer pointer should be set to NULL after kfree.

2007-03-16[PATCH] eCryptfs: fix possible NULL ptr deref in ecryptfs_d_release()Michael Halcrow1-10/+5
ecryptfs_d_release() first dereferences a pointer (via ecryptfs_dentry_to_lower()) and then afterwards checks to see if the pointer it just dereferenced is NULL (via ecryptfs_dentry_to_private()). This patch moves all of the work done on the dereferenced pointer inside a block governed by the condition that the pointer is non-NULL.

2007-03-16[PATCH] ufs: zeroize the rest of block in truncateEvgeniy Dushistov3-18/+35
This patch fix behaviour in such test scenario: lseek(fd, BIG_OFFSET) write(fd, buf, sizeof(buf)) truncate(BIG_OFFSET) truncate(BIG_OFFSET + sizeof(buf)) read(fd, buf...) Because of if file big enough(BIG_OFFSET) we start allocate space by block, ordinary block size > page size, so we should zeroize the rest of block in truncate(except last framgnet, about which VFS should care), to not get garbage, when we extend file. Also patch corrects conversion from pointer to block to physical block number, this helps in case of not common used UFS types. And add to debug output inode number.

This fixes "change blocks numbers on the fly" in case when "prepare write page" is in the call chain, in this case some buffers may be not uptodate and not mapped, we should care to map them and load from disk.

2007-03-16[PATCH] ufs2: more correct work with timeEvgeniy Dushistov2-15/+14
This patch corrects work with time in UFS2 case. 1) According to UFS2 disk layout modification/access and so on "time" should be hold in two variables one 64bit for seconds and another 32bit for nanoseconds, at now for some unknown reason we suppose that "inode time" holds in three variables 32bit for seconds, 32bit for milliseconds and 32bit for nanoseconds. 2) We set amount of nanoseconds in "VFS inode" to 0 during read, instead of getting values from "on disk inode"(this should close http://bugzilla.kernel.org/show_bug.cgi?id=7991).

2007-03-16[CIFS] Do not negotiate new POSIX_PATH_OPERATIONS_CAP yetSteve French1-1/+7
Samba server now expects that clients which send the new POSIX_PATH_OPERATIONS_CAP send all opens with this new SMB - and expects that clients that could send the new posix open/create but don't as indicating that they really want Windows semantics on that handle (which allows Samba to support clients which want to support both types of behaviors on different handles on the same mount) We will put this capability back in the SetFSInfo negotiation with servers like Samba when the new POSIXCreate (create/open/mkdir) code is finished.

2007-03-15[PATCH] sysfs: reinstate exclusion between method calls and attribute ↵Alan Stern2-8/+12
unregistration This patch (as869) reinstates the mutual exclusion between sysfs attribute method calls and attribute unregistration. The previously-reported deadlocks have been fixed, and this exclusion is by far the simplest way to avoid races during driver unbinding. The check for orphaned read-buffers has been moved down slightly, so that the remainder of a partially-read buffer will still be available to userspace even after the attribute has been unregistered.

2007-03-15[PATCH] sysfs and driver core: add callback helper, used by SCSI and S390Alan Stern1-0/+54
This patch (as868) adds a helper routine for device drivers that need to set up a callback to perform some action in a different process's context. This is intended for use by attribute methods that want to unregister themselves or their parent device. Attribute method calls are mutually exclusive with unregistration, so such actions cannot be taken directly. Two attribute methods are converted to use the new helper routine: one for SCSI device deletion and one for System/390 ccwgroup devices.
