2007-06-07RAMFS NOMMU: missed POSIX UID/GID inode attribute checkingBryan Wu
This bug was caught by LTP testcase fchmod06 on Blackfin platform. In the manpage of fchmod, "EPERM: The effective UID does not match the owner of the file, and the process is not privileged (Linux: it does not have the CAP_FOWNER capability)." But the ramfs nommu code missed the inode_change_ok POSIX UID/GID verification. This patch fixed this.

2007-06-06ocfs2: Fix invalid assertion during write on 64k pagesMark Fasheh
The write path code intends to bug if a math error (or unhandled case) results in a write outside of the current cluster boundaries. The actual BUG_ON() statements however are incorrect, leading to a crash on kernels with 64k page size. Fix those by checking against the right variables. Also, move the assertions higher up within the functions so that they trip *before* the code starts to mark buffers. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>

We've had several reoprts of the CPU jumping to 0x00000000 is do_ioctl(). I assume that there's a race and someone is zeroing out the ioctl handler while this CPU waits for the lock_kernel().

2007-05-30NFS: Fix a refcount leakage in O_DIRECTTrond Myklebust
The current code is leaking a reference to dreq->kref when the calls to nfs_direct_read_schedule() and nfs_direct_write_schedule() return an error. This patch moves the call to kref_put() from nfs_direct_wait() back into nfs_direct_read() and nfs_direct_write() (which are the functions that actually took the reference in the first place) fixing the leak.

2007-05-29[XFS] Write at EOF may not update filesize correctly.David Chinner
The recent fix for preventing NULL files from being left around does not update the file size corectly in all cases. The missing case is a write extending the file that does not need to allocate a block. In that case we used a read mapping of the extent which forced the use of the read I/O completion handler instead of the write I/O completion handle. Hence the file size was not updated on I/O completion.

2007-05-25fix compat console unimap regressionHugh Dickins
Why is it that since the 2f1a2ccb9c0de632ab07193becf5f7121794f6ae console UTF-8 fixes went into 2.6.22-rc1, the PowerMac G5 shows only inverse video question marks for the text on tty2-6? whereas tty1 is fine, and so is x86. No fault of that patch: by removing the old fallback behaviour, it reveals that 32-bit setfont running on 64-bit kernels has only really worked on the current console, the rest getting faked by that inadequate fallback. Bring the compat do_unimap_ioctl into line with the main one: PIO_UNIMAP and GIO_UNIMAP apply to the specified tty, not redirected to fg_console. Use the same checks, and most particularly, remember to check access_ok: con_set_unimap and con_get_unimap are using __get_user and __put_user. And the compat vt_check should ask for the same capability as the main one, CAP_SYS_TTY_CONFIG rather than CAP_SYS_ADMIN. Added in vt_ioctl's vc_cons_allocated check for safety, though failure may well be impossible.

2007-05-24NFS: Avoid a deadlock situation on writeTrond Myklebust
When processes are allowed to attempt to lock a non-contiguous range of nfs write requests, it is possible for generic_writepages to 'wrap round' the address space, and call writepage() on a request that is already locked by the same process. We avoid the deadlock by checking if the page index is contiguous with the list of nfs write requests that is already held in our nfs_pageio_descriptor prior to attempting to lock a new request.

2007-05-21Detach sched.h from mm.hAlexey Dobriyan
First thing mm.h does is including sched.h solely for can_do_mlock() inline function which has "current" dereference inside. By dealing with can_do_mlock() mm.h can be detached from sched.h which is good. See below, why. This patch a) removes unconditional inclusion of sched.h from mm.h b) makes can_do_mlock() normal function in mm/mlock.c c) exports can_do_mlock() to not break compilation d) adds sched.h inclusions back to files that were getting it indirectly. e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were getting them indirectly Net result is: a) mm.h users would get less code to open, read, preprocess, parse, ... if they don't need sched.h b) sched.h stops being dependency for significant number of files: on x86_64 allmodconfig touching sched.h results in recompile of 4083 files, after patch it's only 3744 (-8.3%).

2007-05-20[JFFS2] Fix BUG() caused by failing to discard xattrs on deleted files.David Woodhouse
When we cannot mark nodes as obsolete, such as on NAND flash, we end up having to delete inodes with !nlink in jffs2_build_remove_unlinked_inode(). However, jffs2_build_xattr_subsystem() runs later than this, and will attach an xref to the dead inode. Then later when the last nodes of that dead inode are erased we hit a BUG() in jffs2_del_ino_cache() because we're not supposed to get there with an xattr still attached to the inode which is being killed. The simple fix is to refrain from attaching xattrs to inodes with zero nlink, in jffs2_build_xattr_subsystem(). It's it's OK to trust nlink here because the file system isn't actually mounted yet, so there's no chance that a zero-nlink file could actually be alive still because it's open.

grow_dev_page() simply passes GFP_NOFS to find_or_create_page. This means the allocation of radix tree nodes is done with GFP_NOFS and the allocation of a new page is done using GFP_NOFS. The mapping has a flags field that contains the necessary allocation flags for the page cache allocation. These need to be consulted in order to get DMA and HIGHMEM allocations etc right. And yes a blockdev could be allowing Highmem allocations if its a ramdisk.
