git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless John W. Linville says: ==================== pull request: wireless 2013-11-21 Please pull this batch of fixes intended for the 3.13 stream! For the Bluetooth bits, Gustavo says: "A few fixes for 3.13. There is 3 fixes to the RFCOMM protocol. One crash fix to L2CAP. A simple fix to a bad behaviour in the SMP protocol." On top of that... Amitkumar Karwar sends a quintet of mwifiex fixes -- two fixes related to failure handling, two memory leak fixes, and a NULL pointer fix. Felix Fietkau corrects and earlier rt2x00 HT descriptor handling fix to address a crash. Geyslan G. Bem fixes a memory leak in brcmfmac. Larry Finger address more pointer arithmetic errors in rtlwifi. Luis R. Rodriguez provides a regulatory fix in the shared ath code. Sujith Manoharan brings a couple ath9k initialization fixes. Ujjal Roy offers one more mwifiex fix to avoid invalid memory accesses when unloading the USB driver. ==================== Signed-off-by: David S. Miller <[email protected]>

airlied: The lifetime changes introduced in 5bdebb183c9702a8c57a01dff09337be3de337a6 tried to use device_create, however that led to the regression where dev->type wasn't getting set correctly.

2013-11-21KVM: kvm_clear_guest_page(): fix empty_zero_page usageHeiko Carstens1-2/+3
Using the address of 'empty_zero_page' as source address in order to clear a page is wrong. On some architectures empty_zero_page is only the pointer to the struct page of the empty_zero_page. Therefore the clear page operation would copy the contents of a couple of struct pages instead of clearing a page. For kvm only arm/arm64 are affected by this bug. To fix this use the ZERO_PAGE macro instead which will return the struct page address of the empty_zero_page on all architectures.

2013-11-20net: rework recvmsg handler msg_name and msg_namelen logicHannes Frederic Sowa35-115/+67
This patch now always passes msg->msg_namelen as 0. recvmsg handlers must set msg_namelen to the proper size <= sizeof(struct sockaddr_storage) to return msg_name to the user. This prevents numerous uninitialized memory leaks we had in the recvmsg handlers and makes it harder for new code to accidentally leak uninitialized memory. Optimize for the case recvfrom is called with NULL as address. We don't need to copy the address at all, so set it to NULL before invoking the recvmsg handler. We can do so, because all the recvmsg handlers must cope with the case a plain read() is called on them. read() also sets msg_name to NULL. Also document these changes in include/linux/net.h as suggested by David Miller. Changes since RFC: Set msg->msg_name = NULL if user specified a NULL in msg_name but had a non-null msg_namelen in verify_iovec/verify_compat_iovec. This doesn't affect sendto as it would bail out earlier while trying to copy-in the address. It also more naturally reflects the logic by the callers of verify_iovec. With this change in place I could remove " if (!uaddr || msg_sys->msg_namelen == 0) msg->msg_name = NULL ". This change does not alter the user visible error logic as we ignore msg_namelen as long as msg_name is NULL. Also remove two unnecessary curly brackets in ___sys_recvmsg and change comments to netdev style.

2013-11-20btrfs: Use trace condition for get_extent tracepointSteven Rostedt2-3/+4
Doing an if statement to test some condition to know if we should trigger a tracepoint is pointless when tracing is disabled. This just adds overhead and wastes a branch prediction. This is why the TRACE_EVENT_CONDITION() was created. It places the check inside the jump label so that the branch does not happen unless tracing is enabled. That is, instead of doing: if (em) trace_btrfs_get_extent(root, em); Which is basically this: if (em) if (static_key(trace_btrfs_get_extent)) { Using a TRACE_EVENT_CONDITION() we can just do: trace_btrfs_get_extent(root, em); And the condition trace event will do: if (static_key(trace_btrfs_get_extent)) { if (em) { ... The static key is a non conditional jump (or nop) that is faster than having to check if em is NULL or not.

The page pointer information was useless. The bytenr is what you want when you search for submitted write bios. Additionally, a new bit in the print mask is added that allows to selectively enable the check-int submit_bio verbose mode. Before, the global verbose mode had to be enabled leading to many million useless lines in the kernel log.

2013-11-20Btrfs: avoid heavy operations in btrfs_commit_superLiu Bo1-20/+1
The 'git blame' history shows that, the old transaction commit code has to do twice to ensure roots are updated and we have to flush metadata and super block manually, however, right now all of these can be handled well inside the transaction commit code without extra efforts. And the error handling part remains same with the current code, -- 'return to caller once we get error'. This saves us a transaction commit and a flush of super block, which are both heavy operations according to ftrace output analysis.

2013-11-20Btrfs: do not inc uncorrectable_errors counter on ro scrubsIlya Dryomov1-2/+4
Currently if we discover an error when scrubbing in ro mode we a) blindly increment the uncorrectable_errors counter, and b) spam the dmesg with the 'unable to fixup (regular) error at ...' message, even though a) we haven't tried to determine if the error is correctable or not, and b) we haven't tried to fixup anything. Fix this. Cc: Stefan Behrens <[email protected]> Signed-off-by: Ilya Dryomov <[email protected]> Signed-off-by: Josef Bacik <[email protected]> Signed-off-by: Chris Mason <[email protected]>
2013-11-20Btrfs: only drop modified extents if we logged the whole inodeJosef Bacik1-1/+1
If we fsync, seek and write, rename and then fsync again we will lose the modified hole extent because the rename will drop all of the modified extents since we didn't do the fast search. We need to only drop the modified extents if we didn't do the fast search and we were logging the entire inode as we don't need them anymore, otherwise this is being premature.

2013-11-20Btrfs: make sure to copy everything if we renameJosef Bacik1-1/+2
If we rename a file that is already in the log and we fsync again we will lose the new name. This is because we just log the inode update and not the new ref. To fix this we just need to check if we are logging the new name of the inode and copy all the metadata instead of just updating the inode itself. With this patch my testcase now passes.

2013-11-20Btrfs: don't BUG_ON() if we get an error walking backrefsJosef Bacik1-1/+2
We can just return false for this so we stop doing the snapshot aware defrag stuff. Thanks, Signed-off-by: Josef Bacik <[email protected]> Signed-off-by: Chris Mason <[email protected]>
2013-11-20x86, wmi fix modalias_show return valuesPrarit Bhargava1-2/+4
I just fixed this same bug in arch/powerpc/kernel/vio.c and took a quick look for other similar errors in the kernel. modalias_show() should return an empty string on error, not errno.

2013-11-20ipc: Added support for IPC interrupt modeKuppuswamy Sathyanarayanan1-3/+45
This patch adds support for ipc command interrupt mode. Also added platform data option to select 'irq_mode' irq_mode = 1: configure the driver to receive IOC interrupt for each successful ipc_command. irq_mode = 0: makes driver use polling method to track the command completion status.

2013-11-20ipc: Added platform data structureKuppuswamy Sathyanarayanan1-8/+29
Since the same ipc driver can be used by many platforms, using macros for defining ipc_base and i2c_base addresses is not a scalable approach. So added a platform data structure to pass this information.
