We need to setup the network namespace state before we register the notifier. Otherwise if a network device is already registered we get a nasty NULL pointer dereference. Signed-off-by: Eric W. Biederman <ebiederm@maxwell.aristanetworks.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2008-11-06net: Fix recursive descent in __scm_destroy().David S. Miller
__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.

2008-11-06Fix accidental implicit cast in HR-timer conversionDavid Howells
Fix the hrtimer_add_expires_ns() function. It should take a 'u64 ns' argument, but rather takes an 'unsigned long ns' argument - which might only be 32-bits. On FRV, this results in the kernel locking up because hrtimer_forward() passes the result of a 64-bit multiplication to this function, for which the compiler discards the top 32-bits - something that didn't happen when ktime_add_ns() was called directly.

2008-11-06fat: Fix ATTR_RO for directoryOGAWA Hirofumi
FAT has the ATTR_RO (read-only) attribute. But on Windows, the ATTR_RO of the directory will be just ignored actually, and is used by only applications as flag. E.g. it's setted for the customized folder by Explorer. http://msdn2.microsoft.com/en-us/library/aa969337.aspx This adds "rodir" option. If user specified it, ATTR_RO is used as read-only flag even if it's the directory. Otherwise, inode->i_mode is not used to hold ATTR_RO (i.e. fat_mode_can_save_ro() returns 0).

2008-11-06fat: Fix ATTR_RO in the case of (~umask & S_WUGO) == 0OGAWA Hirofumi
If inode->i_mode doesn't have S_WUGO, current code assumes it means ATTR_RO. However, if (~[ufd]mask & S_WUGO) == 0, inode->i_mode can't hold S_WUGO. Therefore the updated directory entry will always have ATTR_RO. This adds fat_mode_can_hold_ro() to check it. And if inode->i_mode can't hold, uses -i_attrs to hold ATTR_RO instead. With this, we don't set ATTR_RO unless users change it via ioctl() if (~[ufd]mask & S_WUGO) == 0. And on FAT_IOCTL_GET_ATTRIBUTES path, this adds ->i_mutex to it for not returning the partially updated attributes by FAT_IOCTL_SET_ATTRIBUTES to userland.

Then this replaces: MSDOS_MKMODE() by fat_make_mode(), fat_attr() by fat_make_attrs(), ->i_attrs = attr & ATTR_UNUSED by fat_save_attrs(). And for root inode, those is used with ATTR_DIR instead of bogus ATTR_NONE.

2008-11-06fat: Kill d_invalidate() in vfat_lookup()OGAWA Hirofumi
d_invalidate() for positive dentry doesn't work in some cases (vfsmount, nfsd, and maybe others). shrink_dcache_parent() by d_invalidate() is pointless for vfat usage at all. So, this kills it, and intead of it uses d_move(). To save old behavior, this returns alias simply for directory (don't change pwd, etc..). the directory lookup shouldn't be important for performance.

2008-11-06fat: Fix/Cleanup dcache handling for vfatOGAWA Hirofumi
- 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.

2008-11-06atmel_serial: keep clock off when it's not neededDavid Brownell
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.

2008-11-06fbdev: fix fb_compat_ioctl() deadlocksGeert Uytterhoeven
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.

2008-11-06memory hotplug: fix page_zone() calculation in test_pages_isolated()Gerald Schaefer
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().

2008-11-06ext3: wait on all pending commits in ext3_sync_fsArthur Jones
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.
