2006-03-17[PATCH] nfsservctl(): remove user-triggerable printkPeter Staubach
A user can use nfsservctl() to spam the logs. This can happen because the arguments to the nfsservctl() system call are versioned. This is a good thing. However, when a bad version is detected, the kernel prints a message and then returns an error.

2006-03-15[PATCH] Fix ext2 readdir f_pos re-validation logicAl Viro
This fixes not one, but _two_, silly (but admittedly hard to hit) bugs in the ext2 filesystem "readdir()" function. It also cleans up the code to avoid the unnecessary goto mess. The bugs were related to re-valiating the f_pos value after somebody had either done an "lseek()" on the directory to an invalid offset, or when the offset had become invalid due to a file being unlinked in the directory. The code would not only set the f_version too eagerly, it would also not update f_pos appropriately for when the offset fixup took place. When that happened, we'd occasionally subsequently fail the readdir() even when we shouldn't (no real harm done, but an ugly printk, and obviously you would end up not necessarily seeing all entries). Thanks to Masoud Sharbiani <masouds@google.com> who noticed the problem and had a test-case for it, and also fixed up a thinko in the first version of this patch.

2006-03-14[PATCH] page migration: fail if page is in a vma flagged VM_LOCKEDChristoph Lameter
page migration currently simply retries a couple of times if try_to_unmap() fails without inspecting the return code. However, SWAP_FAIL indicates that the page is in a vma that has the VM_LOCKED flag set (if ignore_refs ==1). We can check for that return code and avoid retrying the migration. migrate_page_remove_references() now needs to return a reason why the failure occured. So switch migrate_page_remove_references to use -Exx style error messages.

2006-03-15Fix a direct I/O locking issue revealed by the new mutex code.Nathan Scott
Affects only XFS (i.e. DIO_OWN_LOCKING case) - currently it is not possible to get i_mutex locking correct when using DIO_OWN direct I/O locking in a filesystem due to indeterminism in the possible return code/lock/unlock combinations. This can cause a direct read to attempt a double i_mutex unlock inside XFS. We're now ensuring __blockdev_direct_IO always exits with the inode i_mutex (still) held for a direct reader. Tested with the three different locking modes (via direct block device access, ext3 and XFS) - both reading and writing; cannot find any regressions resulting from this change, and it clearly fixes the mutex_unlock warning originally reported here: http://marc.theaimsgroup.com/?l=linux-kernel&m=114189068126253&w=2 Signed-off-by: Nathan Scott <nathans@sgi.com> Acked-by: Christoph Hellwig <hch@lst.de>

2006-03-14[PATCH] NFS: Fix a potential panic in O_DIRECTTrond Myklebust
Based on an original patch by Mike O'Connor and Greg Banks of SGI. Mike states: A normal user can panic an NFS client and cause a local DoS with 'judicious'(?) use of O_DIRECT. Any O_DIRECT write to an NFS file where the user buffer starts with a valid mapped page and contains an unmapped page, will crash in this way. I haven't followed the code, but O_DIRECT reads with similar user buffers will probably also crash albeit in different ways. Details: when nfs_get_user_pages() calls get_user_pages(), it detects and correctly handles get_user_pages() returning an error, which happens if the first page covered by the user buffer's address range is unmapped. However, if the first page is mapped but some subsequent page isn't, get_user_pages() will return a positive number which is less than the number of pages requested (this behaviour is sort of analagous to a short write() call and appears to be intentional). nfs_get_user_pages() doesn't detect this and hands off the array of pages (whose last few elements are random rubbish from the newly allocated array memory) to it's caller, whence they go to nfs_direct_write_seg(), which then totally ignores the nr_pages it's given, and calculates its own idea of how many pages are in the array from the user buffer length. Needless to say, when it comes to transmit those uninitialised page* pointers, we see a crash in the network stack.

OS/2 doesn't initialize the uid, gid, or unix-style permission bits. The uid, gid, & umask mount options perform pretty much like those for the fat file system, overriding what is stored on disk. This is useful for users sharing the file system with OS/2. I implemented a little feature so that if you mask the execute bit, it will be re-enabled on directories when the appropriate read bit is unmasked. I didn't want to implement an fmask & dmask option.

2006-03-08[PATCH] s390: dasd partition detectionHorst Hummel
DASD allows to open a device as soon as gendisk is registered, which means the device is a fake device (capacity=0) and we do know nothing about blocksize and partitions at that point of time. In case the device is opened by someone, the bdev and inode creation is done with the fake device info and the following partition detection code is just using the wrong data.

2006-03-08[PATCH] fix file countingDipankar Sarma
I have benchmarked this on an x86_64 NUMA system and see no significant performance difference on kernbench. Tested on both x86_64 and powerpc. The way we do file struct accounting is not very suitable for batched freeing. For scalability reasons, file accounting was constructor/destructor based. This meant that nr_files was decremented only when the object was removed from the slab cache. This is susceptible to slab fragmentation. With RCU based file structure, consequent batched freeing and a test program like Serge's, we just speed this up and end up with a very fragmented slab - llm22:~ # cat /proc/sys/fs/file-nr 587730 0 758844 At the same time, I see only a 2000+ objects in filp cache. The following patch I fixes this problem. This patch changes the file counting by removing the filp_count_lock. Instead we use a separate percpu counter, nr_files, for now and all accesses to it are through get_nr_files() api. In the sysctl handler for nr_files, we populate files_stat.nr_files before returning to user. Counting files as an when they are created and destroyed (as opposed to inside slab) allows us to correctly count open files with RCU. Signed-off-by: Dipankar Sarma <dipankar@in.ibm.com> Cc: "Paul E.

2006-03-08[PATCH] udf: fix uid/gid options and add uid/gid=ignore and forget optionsPhillip Susi
Fix a bug in udf where it would write uid/gid = 0 to the disk for files owned by the id given with the uid=/gid= mount options. It also adds 4 new mount options: uid/gid=forget and uid/gid=ignore. Without any options the id in core and on disk always match. Giving uid/gid=nnn specifies a default ID to be used in core when the on disk ID is -1. uid/gid=ignore forces the in core ID to allways be used no matter what the on disk ID is. uid/gid=forget forces the on disk ID to always be written out as -1. The use of these options allows you to override ownerships on a disk or disable ownwership information from being written, allowing the media to be used portably between different computers and possibly different users without permissions issues that would require root to correct.

2006-03-06[PATCH] smaps: shared fixNick Piggin
The point of the smaps "shared" is to count the number of pages that are mapped by more than one process, according to Mauricio Lin. However, smaps uses page_count for this, so it will return a false positive for every page that is mapped by just that one process, which is also in pagecache or swapcache. There are false positive situations for anonymous pages not in swapcache as well: - page reclaim, migration - get_user_pages (eg. direct-io, ptrace) Use page_mapcount instead, to count the number of mappings to the page. Use vm_normal_page so that weird things like /dev/mem aren't counted either.

2006-03-05[CIFS] Always match oplock break (cache notification) to the right tcpSteve French
session when multiply mounted. Fixes slow response when cifs client is mounted to shares on multiple servers and oplock break occurs (usually due to attempt to multiply open a file). When treeids on mutiple mounted shares match and we find the wrong match first, we searched for the wrong cached files to send oplock break response for which usually meant that no matching file was found and thus the server would have to timeout the notification. Oplock break timeout is about 20 seconds on some servers so this could cause significantly slower performance on file open calls in a few cases (in particular when multiple shares are mounted from multiple servers, tree ids match, and we have a cached file which is later opened multiple times). This was the most important of the bugs that was found and fixed at Connectathon (interoperability testing event) this week.

2006-03-02[PATCH] v9fs: simplify fid mappingEric Van Hensbergen
v9fs has been plagued by an over-complicated approach trying to map Linux dentry semantics to Plan 9 fid semantics. Our previous approach called for aggressive flushing of the dcache resulting in several problems (including wierd cwd behavior when running /bin/pwd). This patch dramatically simplifies our handling of this fid management. Fids will not be clunked as promptly, but the new approach is more functionally correct. We now clunk un-open fids only when their dentry ref_count reaches 0 (and d_delete is called). Another simplification is we no longer seek to match fids to the process-id or uid of the action initiator. The uid-matching will need to be revisited when we fix the security model.
