Fix Altix system controller (snsc) device names to include the slot number of the blade whose associated system controller is the target of the device interface. Including the slot number avoids a problem we're currently having where slots within the same enclosure are attempting to create multiple kobjects with identical names. Signed-off-by:

reiserfs_cache_default_acl() should return whether we successfully found the acl or not. We have to return correct value even if reiserfs_get_acl() returns error code and not just 0. Otherwise callers such as reiserfs_mkdir() can unnecessarily lock the xattrs and later functions such as reiserfs_new_inode() fail to notice that we have already taken the lock and try to take it again with obvious consequences.

Repair /proc/devices early-termination regression. 2.6.16 broke /proc/devices. An application often gets an EOF before the end of data is reached, if that application uses a series of short read(2)s to access the data. I have used read buffers of varying sizes with varying degrees of unsuccess (larger sizes get further into the data than smaller sizes, following a simple pattern). It appears that the only safe way to get the data is to use a single read buffer larger than all the data in /proc/devices. The following example demonstates the problem: # dd if=/proc/devices bs=1 Character devices: 1 mem 27+0 records in 27+0 records out This patch is a backport of the fix recently accepted to Linus's tree: commit 68eef3b4 [PATCH] Simplify proc/devices and fix early termination regression It replaces the complex, state-machine algorithm introduced in 2.6.16 with a simple algorithm, modeled on the implementation of /proc/interrupts.

Before removing a snapshot, wait for the completion of any kcopyd jobs using it. Do this by maintaining a count (nr_jobs) of how many outstanding jobs each kcopyd_client has. The snapshot destructor first unregisters the snapshot so that no new kcopyd jobs (created by writes to the origin) will reference that particular snapshot. kcopyd_client_destroy() is now run next to wait for the completion of any outstanding jobs before the snapshot exception structures (that those jobs reference) are freed.

This patch prevents a bug where the frontend is unable to tune after waking from powered down state. Now, the device remains powered on until it is disconnected, just like the windows driver. It seems that the bluebird firmware is unable to successfully handle tuning after a powered down state. This patch fixes all of the FusionHDTV Bluebird USB2 devices. The Medion MD95700 will still behave as before, since it was unaffected by this bug. Signed-off-by:

We do this by removing a micro-optimization that tries to avoid grabbing the iommu_bitmap_lock spinlock and using a bus-locked operation. This still races with other simultaneous alloc_iommu or free_iommu(size > 1) which both use bus-unlocked operations. The end result of this race is eventually ending up with an iommu_gart_bitmap that has bits errornously set all over, making large contiguous iommu space allocations fail with 'PCI-DMA: Out of IOMMU space'.

This quietens warnings and actually fixes a bug. The unwind tables would come out wrong without -32, causing pthread cancellation during them to crash in the gcc runtime.

hi, The motivation behind the patch below was to address messages in /var/log/messages such as: Jan 31 10:54:15 mets kernel: audit(:0): major=252 name_count=0: freeing multiple contexts (1) Jan 31 10:54:15 mets kernel: audit(:0): major=113 name_count=0: freeing multiple contexts (2) I can reproduce by running 'get-edid' from: http://john.fremlin.de/programs/linux/read-edid/. These messages come about in the log b/c the vm86 calls do not exit via the normal system call exit paths and thus do not call 'audit_syscall_exit'. The next system call will then free the context for itself and for the vm86 context, thus generating the above messages. This patch addresses the issue by simply adding a call to 'audit_syscall_exit' from the vm86 code. Besides fixing the above error messages the patch also now allows vm86 system calls to become auditable. This is useful since strace does not appear to properly record the return values from sys_vm86. I think this patch is also a step in the right direction in terms of cleaning up some core auditing code. If we can correct any other paths that do not properly call the audit exit and entries points, then we can also eliminate the notion of context chaining. I've tested this patch by verifying that the log messages no longer appear, and that the audit records for sys_vm86 appear to be correct. Also, 'read_edid' produces itentical output. thanks, -Jason Signed-off-by:

[PATCH] cs5535_gpio.c: call cdev_del() during module_exit to unmap kobject references and other cleanups During module unloading, cdev_del() must be called to unmap cdev related kobject references and other cleanups(such as inode->i_cdev being set to NULL) which prevents the OOPS upon subsequent loading, usage and unloading of modules(as seen in the mail thread http://marc.theaimsgroup.com/?l=linux-kernel&m=114533640609018&w=2).

Recently when we use this "ULI M1573" south bridge chip found that can't mount CDROM(VCD) smoothly, must waiting for a long time. After I check the "ULI M1573" south bridge datasheet, I found the reason. The reason is the "ULI M1573" version in the Linux is "0xC7" not "0xC4" anymore So I was modified the source than it was successed.

Fix the "apm: set display: Interface not engaged" error on Armada laptops again. Jordan said: I think this is fine. It seems to me that this may be the fault of one or both of the APM solutions handling this situation in a non-standard way, but since APM is used very little on the Geode, and I have direct access to our BIOS folks, if this problem comes up with a customer again, we'll solve it from the firmware.

There are places in the kernel where we look up files in fd tables and access the file structure without holding refereces to the file. So, we need special care to avoid the race between looking up files in the fd table and tearing down of the file in another CPU. Otherwise, one might see a NULL f_dentry or such torn down version of the file. This patch fixes those special places where such a race may happen. Signed-off-by:

I was looking into random driver code and found a suspicious looking memcpy() in drivers/char/ipmi/ipmi_bt_sm.c on 2.6.17-rc1: if ((size < 2) || (size > IPMI_MAX_MSG_LENGTH)) return -1; ... memcpy(bt->write_data + 3, data + 1, size - 1); where sizeof bt->write_data is IPMI_MAX_MSG_LENGTH. It looks like the memcpy would overflow by 2 bytes if size == IPMI_MAX_MSG_LENGTH. A patch attached to limit size to (IPMI_MAX_LENGTH - 2). Cc: Corey Minyard <minyard@acm.org> Signed-off-by:

x86: be careful about tailcall breakage for sys_open[at] too Came up through a quick grep for other cases similar to the ftruncate() one in commit 0a489cb3. Also, add a comment, so that people who read the code understand why we do what looks like a no-op. (Again, this won't actually matter to any sane user, since libc will save and restore the register gcc stomps on, but it's still wrong to stomp on it) Signed-off-by:

x86: don't allow tail-calls in sys_ftruncate[64]() Gcc thinks it owns the incoming argument stack, but that's not true for "asmlinkage" functions, and it corrupts the caller-set-up argument stack when it pushes the third argument onto the stack. Which can result in %ebx getting corrupted in user space. Now, normally nobody sane would ever notice, since libc will save and restore %ebx anyway over the system call, but it's still wrong. I'd much rather have "asmlinkage" tell gcc directly that it doesn't own the stack, but no such attribute exists, so we're stuck with our hacky manual "prevent_tail_call()" macro once more (we've had the same issue before with sys_waitpid() and sys_wait4()).

[TCP]: Fix truesize underflow There is a problem with the TSO packet trimming code. The cause of this lies in the tcp_fragment() function. When we allocate a fragment for a completely non-linear packet the truesize is calculated for a payload length of zero. This means that truesize could in fact be less than the real payload length. When that happens the TSO packet trimming can cause truesize to become negative. This in turn can cause sk_forward_alloc to be -n * PAGE_SIZE which would trigger the warning. I've copied the code DaveM used in tso_fragment which should work here. Signed-off-by:
