We used to have sync_blockdev() on each normal (== non-raw) blkdev_put() + kill_bdev() on the final blkdev_put(). That worked fine until we'd moved sync_blockdev() to the final blkdev_put(). Now we have a nasty scenario: open block device open raw device write on block device # data ends up in cache close block device # no sync here, we still have the sucker opened close raw device # no sync here either # ... and cache is killed by kill_bdev() IOW, if we postpone sync to final close, we must do it regardless of kind of close. Otherwise we are in for data corruption and yes, it is easy to trigger. Fix is obvious...

kunmap_atomic() takes a kernel-virtual address, not a pageframe address. (Very common problem. We really should make the atomic kmap functions type-safe).

There's a fencepost error in the GART IOMMU handling on x86_64 in the unmap path. When testing to see if the bus address is within the IOMMU window and needs to be unmapped, the start of the first page *beyond* the window also passes the test. This can cause the first doubleword of the next page beyond the gatt table to be smashed to zero, with unpredictable results depending on what that page is used for.

The attached trivial patch should fix the "i1-dig" build failure reported on this page: http://www.gelato.unsw.edu.au/kerncomp/ and should make it easier to build a properly configured ia64 kernel.

This is a cleaned-up version of a mremap() fix for "move_one_page()" by Rajesh Venkatasubramanian <vrajesh@umich.edu>. We could use a NULL "src" pointer. Because while we do hold the MM semaphore over the whole sequence, the destination page table allocation will possibly drop the page table spinlock. That in turn can cause a clean source page to be stolen by page reclaim, causing the source-side "get_one_pte_map_nested()" to return NULL the second time around even if it didn't on the first case. So we just check "src" again, and get rid of the bogus TLB invalidate while we're at it.

My "__ide_dma_off()" cleanup uncovered some code that shouldn't be compiled when CONFIG_BLK_DEV_IDEDMA=n. Fix it and kill a warning in setup-pci.c. Noticed by Martin Diehl <lists@mdiehl.de>.

There's an incorrect redefinition extern/static in prep_pci. Just remove it.

From: Tom Rini <trini@kernel.crashing.org> Hello. The following patch is all that is required to get current 2.6 to compile and work on MPC82xx platforms.

From: Tom Rini <trini@kernel.crashing.org> Replace MSR_, which is gone now, with the value it used to be. Required to get the MPC82xx platforms compiling again.

This fixes the build of "allyesconfig", old and new radeonfb's would collide on some symbols.

It results in serial console getting initialised really late and the suggested workaround is broken according to Keith. Cset exclude: akpm@osdl.org|ChangeSet|20040213234712|28554

The rtasd kernel thread would exit before daemoniz'ing itself if RTAS wasn't present (or if allocation of the buffer failed), thus leaving a zombie. This patch fixes it (and remove #if 0'ed code)

Move ide-dma.c:__ide_dma_off() outside of #ifdef CONFIG_BLK_DEV_IDEDMA_PCI, so it can be used for all DMA capable hosts. Remove ide_hwif_t->ide_dma_off.

->ide_dma_count() was introduced in kernel 2.5.35 and was meant to add support for host FIFO counters (for VDMA), but is only a wrapper for ->ide_dma_begin() (even for siimage.c b/c SIIMAGE_VIRTUAL_DMAPIO is undefined). Moreover it should be possible to add VDMA code directly to ->ide_dma_begin().

Use __ide_dma_{good,bad}_drive() directly and remove these wrappers.

I see only pros of removing OnStream support: - SCSI osst.c driver is actively maintained by Willem Riede <wrlk@riede.org> - there is no functionality loss (OnStream IDE drives don't support DSC) - ide-tape.c driver is too ugly & complicated even without OnStream support - long term benefits (2.7.x plans on unifying storage drivers)

From: James Morris <jmorris@redhat.com> The patch below fixes an error handling flaw, where we need to return a Netfilter verdict from the function rather than a standard error code.

From: James Morris <jmorris@redhat.com> The avc_init function is only called during kernel init, so it can be marked with __init.

From: Stephen Smalley <sds@epoch.ncsc.mil> This patch changes the mode bits on the selinuxfs enforce node so that non-root processes can read it. This is necessary to allow non-root userspace policy enforcers to check the enforcing flag upon a permission failure as well. A process must still have the appropriate SELinux permission in order to read the node.

From: James Morris <jmorris@redhat.com> This patch implements context mount support within SELinux. Three new mount options are provided: context=%s Label the entire filesystem with the specified security context during mount and change the labeling behavior to 'mountpoint labeling'. The /proc/self/attr/fscreate attribute will be ignored for file creation on the filesystem, although policy-specified transitions will still work normally. This also sets the aggregate filesystem security context. fscontext=%s Set the label of the aggregate filesystem to the specified security context, so that SELinux policy controls over the filesystem itself may be reinstated. Only works for filesystems without EA labeling support, and is not valid if 'context' has been specified. defcontext=%s Set the default security context for files created in this filesystem to the specified security context (as opposed to the current global default). Only works for filesystems without EA labeling support, and is not valid if 'context' has been specified. To set the context or fscontext options, the security policy must specify appropriate permissions for the filesystem relabelfrom and filesystem relabelto controls. For the defcontext option, the filesystem relablefrom and filesystem assoicate controls are invoked. The security mount options are parsed out and stripped from the normal mount option data so that no normal filesystems need to be aware of them. Filesystems with binary mount option data (e.g. NFS, SMBFS, AFS, Coda) need to be handled as special cases: only NFS is supprted at this stage per the previous patch.

From: James Morris <jmorris@redhat.com> This patch modifies the kernel's NFS mount data structure to include SELinux context mount data. It allows NFS fileystems to be labeled on a per-mountpoint basis, and should not affect existing versions of userspace mount. (A patch to the userspace mount code is available at http://people.redhat.com/jmorris/selinux/context_mounts/)

Andrew Morton authored
From: James Morris <jmorris@redhat.com> This series of patches adds support for SELinux 'context mounts', which allows filesystems to be assigned security context information at mount time. For example, some filesystems do not support extended attributes (e.g. NFS, vfat), and this feature allows security contexts to be assigned to them on a per-mountpoint basis. It is also useful when the existing labeling on a filesystem is untrusted or unwanted for some reason (e.g. removable media), and needs to be overridden with a safe default. The first patch below consists of infrastructure changes to the kernel: - A new LSM hook has been added, sb_copy_data, which allows the security module to copy security-specific mount data once the superblock has been setup by the filesystem. - The sb_kern_mount hook has been modified to take this security data as a parameter, and would typically be used at that point to configure the security parameters of the filesystem being mounted. - Allocation and freeing of the security data has been implemented in the core fs code as it is cleaner than trying to do it purely via LSM hooks, and should make maintenance easier. This code will be compiled away if LSM is not enabled.
