| * ocfs2: Fix invalid assertion during write on 64k pagesMark Fasheh2007-06-061-10/+10
| | | | | | | | | | | | | | | | | | | | | | | | 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>

* | RAMFS NOMMU: missed POSIX UID/GID inode attribute checkingBryan Wu2007-06-071-0/+5
|/ | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | An xattr_datum which ends up orphaned should be freed by the GC thread. But if we umount before the GC thread is finished, or if we mount read-only and the GC thread never runs, they might never be freed. Clean them up during unmount, if there are any left.

| * [JFFS2] Fix BUG() caused by failing to discard xattrs on deleted files.David Woodhouse2007-05-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

* | [XFS] Write at EOF may not update filesize correctly.David Chinner2007-05-291-9/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | fix compat console unimap regressionHugh Dickins2007-05-251-8/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | | Detach sched.h from mm.hAlexey Dobriyan2007-05-2152-11/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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%). Cross-compile tested on all arm defconfigs, all mips defconfigs, all powerpc defconfigs, alpha alpha-up arm i386 i386-up i386-defconfig i386-allnoconfig ia64 ia64-up m68k mips parisc parisc-up powerpc powerpc-up s390 s390-up sparc sparc-up sparc64 sparc64-up um-x86_64 x86_64 x86_64-up x86_64-defconfig x86_64-allnoconfig as well as my two usual configs.

* | | Fix "fs: convert core functions to zero_user_page"OGAWA Hirofumi2007-05-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The bug was introduced by 01f2705daf5a36208e69d7cf95db9c330f843af6. It misses to convert the first argument, it should be "new_page". This became a cause of fatfs corruption.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The timerfd was using the unlocked waitqueue operations, but it was using a different lock, so poll_wait() would race with it. This makes timerfd directly use the waitqueue lock. Signed-off-by: Davide Libenzi <davidel@xmailserver.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
