* fat: Fix/Cleanup dcache handling for vfatOGAWA Hirofumi2008-11-061-44/+80
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Add comments for handling dcache of vfat. - Separate case-sensitive case and case-insensitive to vfat_revalidate() and vfat_ci_revalidate(). vfat_revalidate() doesn't need to drop case-insensitive negative dentry on creation path. - Current code is missing to set ->d_revalidate to the negative dentry created by unlink/etc.. This sets ->d_revalidate always, and returns 1 for positive dentry. Now, we don't need to change ->d_op dynamically anymore, so this just uses sb->s_root->d_op to set ->d_op. - d_find_alias() may return DCACHE_DISCONNECTED dentry. It's not the interesting dentry there. This checks it. - Add missing LOOKUP_PARENT check. We don't need to drop the valid negative dentry for (LOOKUP_CREATE | LOOKUP_PARENT) lookup. - For consistent filename on creation path, this drops negative dentry if we can't see intent.

* atmel_serial: keep clock off when it's not neededDavid Brownell2008-11-061-3/+14
| | | | | | | | | | | | | | | | | | | | | | The atmel_serial driver is mismanaging its clock by leaving it on at all times ... the whole point of clock management is to leave it off unless it's actively needed, which conserves power!! Although the kernel doesn't actually hang without my fix, it does discard quite a lot of early console output. The result still looks correct: usart users= 1 on 35000000 Hz, for atmel_usart.0 usart users= 0 off 35000000 Hz, for atmel_usart.2 when using ttyS0 as serial console.

* fbdev: fix fb_compat_ioctl() deadlocksGeert Uytterhoeven2008-11-061-24/+39
| | | | | | | | | | | | | | | | | | | | | | | | | commit 3e680aae4e53ab54cdbb0c29257dae0cbb158e1c ("fb: convert lock/unlock_kernel() into local fb mutex") introduced several deadlocks in the fb_compat_ioctl() path, as mutex_lock() doesn't allow recursion, unlike lock_kernel(). This broke frame buffer applications on 64-bit systems with a 32-bit userland. commit 120a37470c2831fea49fdebaceb5a7039f700ce6 ("framebuffer compat_ioctl deadlock") fixed one of the deadlocks. This patch fixes the remaining deadlocks: - Revert commit 120a37470c2831fea49fdebaceb5a7039f700ce6, - Extract the core logic of fb_ioctl() into a new function do_fb_ioctl(), - Change all callsites of fb_ioctl() where info->lock is already held to call do_fb_ioctl() instead, - Add sparse annotations to all routines that take info->lock.

* memory hotplug: fix page_zone() calculation in test_pages_isolated()Gerald Schaefer2008-11-061-2/+3
| | | | | | | | | | | | | | | | | My last bugfix here (adding zone->lock) introduced a new problem: Using page_zone(pfn_to_page(pfn)) to get the zone after the for() loop is wrong. pfn will then be >= end_pfn, which may be in a different zone or not present at all. This may lead to an addressing exception in page_zone() or spin_lock_irqsave(). Now I use __first_valid_page() again after the loop to find a valid page for page_zone().

* ext3: wait on all pending commits in ext3_sync_fsArthur Jones2008-11-061-6/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In ext3_sync_fs, we only wait for a commit to finish if we started it, but there may be one already in progress which will not be synced. In the case of a data=ordered umount with pending long symlinks which are delayed due to a long list of other I/O on the backing block device, this causes the buffer associated with the long symlinks to not be moved to the inode dirty list in the second phase of fsync_super. Then, before they can be dirtied again, kjournald exits, seeing the UMOUNT flag and the dirty pages are never written to the backing block device, causing long symlink corruption and exposing new or previously freed block data to userspace. This can be reproduced with a script created by Eric Sandeen <sandeen@redhat.com>: #!/bin/bash umount /mnt/test2 mount /dev/sdb4 /mnt/test2 rm -f /mnt/test2/* dd if=/dev/zero of=/mnt/test2/bigfile bs=1M count=512 touch /mnt/test2/thisisveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryverylongfilename ln -s /mnt/test2/thisisveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryverylongfilename /mnt/test2/link umount /mnt/test2 mount /dev/sdb4 /mnt/test2 ls /mnt/test2/ umount /mnt/test2 To ensure all commits are synced, we flush all journal commits now when sync_fs'ing ext3.

* hugetlbfs: handle pages higher order than MAX_ORDERAndy Whitcroft2008-11-062-1/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | When working with hugepages, hugetlbfs assumes that those hugepages are smaller than MAX_ORDER. Specifically it assumes that the mem_map is contigious and uses that to optimise access to the elements of the mem_map that represent the hugepage. Gigantic pages (such as 16GB pages on powerpc) by definition are of greater order than MAX_ORDER (larger than MAX_ORDER_NR_PAGES in size). This means that we can no longer make use of the buddy alloctor guarentees for the contiguity of the mem_map, which ensures that the mem_map is at least contigious for maximmally aligned areas of MAX_ORDER_NR_PAGES pages. This patch adds new mem_map accessors and iterator helpers which handle any discontiguity at MAX_ORDER_NR_PAGES boundaries. It then uses these to implement gigantic page versions of copy_huge_page and clear_huge_page, and to allow follow_hugetlb_page handle gigantic pages.

| | | | | | | | | | | | When fixing up invalid years rtc_read_alarm() was calling rtc_valid_tm() as a boolean but rtc_valid_tm() returns zero on success or a negative number if the time is not valid so the test was inverted.

* vt: incomplete initialization of vc_tab_stopWolfgang Kroworsch2008-11-061-2/+8
| | | | | | | | | | | | | | | | | | | | | | Problem 1 (see patch below): vc_tab_stop is declared as an array of 8 unsigned ints in struct vc_data in include/linux/console_struct.h . In drivers/char/vt.c only 5 of these 8 unsigned ints get initialized leading to unintended tabulator placement on displays with more than 160 columns text. Problem 2 (open): Upcoming displays will have more than 256 columns of text leading to invalid memory access in drivers/char/vt.c during tabulator calculations: if (vc->vc_tab_stop[vc->vc_x >> 5] & (1 << (vc->vc_x & 31))) break; Signed-off-by: Wolfgang Kroworsch <wolfgang@kroworsch.de> Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Cc: Christoph Hellwig <hch@lst.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* net: Fix recursive descent in __scm_destroy().David Miller2008-11-063-5/+26
| | | | | | | | | | | | | | | | | __scm_destroy() walks the list of file descriptors in the scm_fp_list pointed to by the scm_cookie argument. Those, in turn, can close sockets and invoke __scm_destroy() again. There is nothing which limits how deeply this can occur. The idea for how to fix this is from Linus. Basically, we do all of the fput()s at the top level by collecting all of the scm_fp_list objects hit by an fput(). Inside of the initial __scm_destroy() we keep running the list until it is empty.

| | | | | | | | | | | | | | | | | | | | The current code read nothing but zeros on big-endian (wrong part of the 32bits). This caused poor performance on big-endian machines. Though this issue did not cause the system to crash, the performance is significantly better with the fix so I view it as critical bug fix.

| * mv643xx_eth: fix SMI bus access timeoutsLennert Buytenhek2008-11-031-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mv643xx_eth mii bus implementation uses wait_event_timeout() to wait for SMI completion interrupts. If wait_event_timeout() would return zero, mv643xx_eth would conclude that the SMI access timed out, but this is not necessarily true -- wait_event_timeout() can also return zero in the case where the SMI completion interrupt did happen in time but where it took longer than the requested timeout for the process performing the SMI access to be scheduled again. This would lead to occasional SMI access timeouts when the system would be under heavy load. The fix is to ignore the return value of wait_event_timeout(), and to re-check the SMI done bit after wait_event_timeout() returns to determine whether or not the SMI access timed out.
