2011-01-19cifs: make wait_for_free_request take a TCP_Server_Info pointerJeff Layton

2011-01-19cifs: no need to mark smb_ses_list as cifs_demultiplex_thread is exitingJeff Layton
The TCP_Server_Info is refcounted and every SMB session holds a reference to it. Thus, smb_ses_list is always going to be empty when cifsd is coming down. This is dead code.

2011-01-19cifs: don't fail writepages on -EAGAIN errorsJeff Layton
If CIFSSMBWrite2 returns -EAGAIN, then the error should be considered temporary. CIFS should retry the write instead of setting an error on the mapping and returning. For WB_SYNC_ALL, just retry the write immediately. In the WB_SYNC_NONE case, call redirty_page_for_writeback on all of the pages that didn't get written out and then move on. Also, fix up the handling of a short write with a successful return code. MS-CIFS says that 0 bytes_written means ENOSPC or EFBIG. It doesn't mention what a short, but non-zero write means, so for now treat it as we would an -EAGAIN return.

2011-01-19CIFS: Fix oplock break handling (try #2)Pavel Shilovsky
When we get oplock break notification we should set the appropriate value of OplockLevel field in oplock break acknowledge according to the oplock level held by the client in this time. As we only can have level II oplock or no oplock in the case of oplock break, we should be aware only about clientCanCacheRead field in cifsInodeInfo structure. Also fix bug connected with wrong interpretation of OplockLevel field during oplock break notification processing.

2011-01-19ceph: avoid immediate cap check after importSage Weil
The NODELAY flag avoids the heuristics that delay cap (issued/wanted) release. There's no reason for that after we import a cap, and it kills whatever benefit we get from those delays. Signed-off-by: Sage Weil <sage@newdream.net>
2011-01-19ceph: fix flushing of caps vs cap importSage Weil
If we are mid-flush and a cap is migrated to another node, we need to resend the cap flush message to the new MDS, and do so with the original flush_seq to avoid leaking across a sync boundary. Previously we didn't redo the flush (we only flushed newly dirty data), which would cause a later sync to hang forever. Signed-off-by: Sage Weil <sage@newdream.net>

2011-01-19Bluetooth: Fix race condition with conn->sec_levelJohan Hedberg
The conn->sec_level value is supposed to represent the current level of security that the connection has. However, by assigning to it before requesting authentication it will have the wrong value during the authentication procedure. To fix this a pending_sec_level variable is added which is used to track the desired security level while making sure that sec_level always represents the current level of security.

2011-01-19Bluetooth: Fix authentication request for L2CAP raw socketsJohan Hedberg
When there is an existing connection l2cap_check_security needs to be called to ensure that the security level of the new socket is fulfilled. Normally l2cap_do_start takes care of this, but that function doesn't get called for SOCK_RAW type sockets. This patch adds the necessary l2cap_check_security call to the appropriate branch in l2cap_do_connect.

2011-01-19Bluetooth: Create a unified auth_type evaluation functionJohan Hedberg
The logic for determining the needed auth_type for an L2CAP socket is rather complicated and has so far been duplicated in l2cap_check_security as well as l2cap_do_connect. Additionally the l2cap_check_security code was completely missing the handling of SOCK_RAW type sockets.

2011-01-19Revert "Bluetooth: Update sec_level/auth_type for already existing connections"Johan Hedberg
This reverts commit 045309820afe047920a50de25634dab46a1e851d. That commit is wrong for two reasons: - The conn->sec_level shouldn't be updated without performing authentication first (as it's supposed to represent the level of security that the existing connection has) - A higher auth_type value doesn't mean "more secure" like the commit seems to assume. E.g. dedicated bonding with MITM protection is 0x03 whereas general bonding without MITM protection is 0x04. hci_conn_auth already takes care of updating conn->auth_type so hci_connect doesn't need to do it.

2011-01-19blkio-throttle: Avoid calling blkiocg_lookup_group() for root groupVivek Goyal
o Jeff Moyer was doing some testing on a RAM backed disk and blkiocg_lookup_group() showed up high overhead after memcpy(). Similarly somebody else reported that blkiocg_lookup_group() is eating 6% extra cpu. Though looking at the code I can't think why the overhead of this function is so high. One thing is that it is called with very high frequency (once for every IO). o For lot of folks blkio controller will be compiled in but they might not have actually created cgroups. Hence optimize the case of root cgroup where we can avoid calling blkiocg_lookup_group() if IO is happening in root group (common case).

The current hdpvr code kmalloc's a new buffer for every i2c read and write. Rather than do that, lets allocate a buffer in the driver's device struct and just use that every time. The size I've chosen for the buffer is the maximum size I could ascertain might be used by either ir-kbd-i2c or lirc_zilog, plus a bit of padding (lirc_zilog may use up to 100 bytes on tx, rounded that up to 128).

2011-01-19[media] hdpvr: enable IR partJarod Wilson
A number of things going on here, but the end result is that the IR part on the hdpvr gets enabled, and can be used with ir-kbd-i2c and/or lirc_zilog. First up, there are some conditional build fixes that come into play whether i2c is built-in or modular. Second, we're swapping out i2c_new_probed_device() for i2c_new_device(), as in my testing, probing always fails, but we *know* that all hdpvr devices have a z8 chip at 0x70 and 0x71. Third, we're poking at an i2c address directly without a client, and writing some magic bits to actually turn on this IR part (this could use some improvement in the future). Fourth, some of the i2c_adapter storage has been reworked, as the existing implementation used to lead to an oops following i2c changes c. 2.6.31. Earlier editions of this patch have been floating around the 'net for a while, including being patched into Fedora kernels, and they *do* work. This specific version isn't yet tested, beyond loading ir-kbd-i2c and confirming that it does bind to the RX address of the hdpvr. [mchehab@redhat.com: I2C_CLASS_TV_ANALOG is not defined.

2011-01-19[media] v4l2-device: fix 'use-after-freed' oopsHans Verkuil
Fix a bug in v4l2_device_unregister where the sd pointer can be dereferenced after it was freed. Normally the i2c adapter is removed before this function is called. Removing the adapter will also unregister all subdevs on that adapter, so generally v4l2_device_unregister has nothing to do. However, in the case of a platform i2c bus that bus is generally not freed. In that case, after freeing the i2c subdevice the code will fall into the second block when it tests if the subdev is a SPI device. But by that time the subdev is already freed and the kernel oopses. The fix is trivial: continue with the loop after freeing the i2c or spi subdevice.

This reverts a portion of commit 44243fc2ef99948bc9b046901880885616dd5e89 A commit for which I errantly recommended that defaults for I2C address 0x71 not be set by ir-kbd-i2c.c The pvrusb2 and bttv drivers currently rely on ir-kbd-i2c setting defaults for that address. Until I can get those bridge drivers fixed to properly send IR_i2c_init_data for boards with Zilog Z8 chips, just add back the default settings for I2C address 0x71.

2011-01-19[media] lirc_zilog: Remove unneeded tests for existence of the IR Tx functionAndy Walls
The driver is now structured so that it must handle an IR Tx unit for a Z8 IR chip, or it refuses to handle that Z8 IR chip. This allows us to assume that ir->tx != NULL in a few places in the driver, and also allows us to always report Tx is available to userspace. Get rid of unneeded tests for ir->tx == NULL and always report that Tx is available. Signed-off-by: Andy Walls <awalls@md.metrocast.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2011-01-19[media] lirc_zilog: Update IR Rx polling kthread start/stop and some printksAndy Walls
The IR Rx polling thread was originally a kernel_thread long ago, and had only been minimally converted to a kthread. This patch finishes that conversion by - cleaning up all the unneeded completions - destroying the kthread properly by calling kthread_stop() - changing lirc_thread() to test kthread_should_stop() just before every point where it may sleep - reorganizing the lirc_thread() function so it uses fewer lines - modifying the name of the kthread from "lirc_zilog" to "zilog-rx-i2c-N", so ps will show which kthread polls which Zilog Z8 IR unit. Also some minor tweaks were made to logging emitted by the ir_probe() function. Signed-off-by: Andy Walls <awalls@md.metrocast.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
