When the dlc is closed, rfcomm_dev_state_change() tries to release the port in the case it cannot get a reference to the tty. However this is racy and not even needed. Infact as Peter Hurley points out: 1. Only consider dlcs that are 'stolen' from a connected socket, ie. reused. Allocated dlcs cannot have been closed prior to port activate and so for these dlcs a tty reference will always be avail in rfcomm_dev_state_change() -- except for the conditions covered by #2b below. 2. If a tty was at some point previously created for this rfcomm, then either (a) the tty reference is still avail, so rfcomm_dev_state_change() will perform a hangup. So nothing to do, or, (b) the tty reference is no longer avail, and the tty_port will be destroyed by the last tty_port_put() in rfcomm_tty_cleanup. Again, no action required. 3. Prior to obtaining the dlc lock in rfcomm_dev_add(), rfcomm_dev_state_change() will not 'see' a rfcomm_dev so nothing to do here. 4. After releasing the dlc lock in rfcomm_dev_add(), rfcomm_dev_state_change() will 'see' an incomplete rfcomm_dev if a tty reference could not be obtained. Again, the best thing to do here is nothing. Any future attempted open() will block on rfcomm_dev_carrier_raised(). The unconnected device will exist until released by ioctl(RFCOMMRELEASEDEV). The patch removes the aforementioned code and uses the tty_port_tty_hangup() helper to hangup the tty. Signed-off-by:Gianluca Anzolin <gianluca@sottospazio.it> Reviewed-by:

We need to let the setup stage complete cleanly even when the HCI device is rfkilled. Otherwise the HCI device will stay in an undefined state and never get notified to user space through mgmt (even when it gets unblocked through rfkill). This patch makes sure that hci_dev_open() can be called in the HCI_SETUP stage, that blocking the device doesn't abort the setup stage, and that the device gets proper powered down as soon as the setup stage completes in case it was blocked meanwhile. The bug that this patch fixed can be very easily reproduced using e.g. the rfkill command line too. By running "rfkill block all" before inserting a Bluetooth dongle the resulting HCI device goes into a state where it is never announced over mgmt, not even when "rfkill unblock all" is run.

This makes it more convenient to check for rfkill (no need to check for dev->rfkill before calling rfkill_blocked()) and also avoids potential races if the RFKILL state needs to be checked from within the rfkill callback. Signed-off-by:

For certain devices (ex: HID mouse), support for authentication, pairing and bonding is optional. For such devices, the ACL alive for too long after the L2CAP disconnection. To avoid the ACL alive for too long after L2CAP disconnection, reset the ACL disconnect timeout back to HCI_DISCONN_TIMEOUT during L2CAP connect.

While playing the peripheral role, the host gets a LE Long Term Key Request Event from the controller when a connection is established with a bonded device. The host then informs the LTK which should be used for the connection. Once the link is encrypted, the host gets an Encryption Change Event. Therefore we should set conn->pending_sec_level instead of conn-> sec_level in hci_le_ltk_request_evt. This way, conn->sec_level is properly updated in hci_encrypt_change_evt. Moreover, since we have a LTK associated to the device, we have at least BT_SECURITY_MEDIUM security level. Cc: Stable <stable@vger.kernel.org> Signed-off-by:

In case of __dev_alloc_skb() failure rtl8187_init_urbs() calls usb_free_urb(entry) where 'entry' can points to urb allocated at the previous iteration. That means refcnt will be decremented incorrectly and the urb can be used after memory deallocation. The patch fixes the issue and implements error handling of init_urbs in rtl8187_start().

The kernel configuration for the driver could result in compilation issues as reported by Randy Dunlap. His results are show below: "on x86_64: when CONFIG_MMC=m CONFIG_BRCMUTIL=y CONFIG_BRCMFMAC=y CONFIG_BRCMFMAC_SDIO=y This bool kconfig symbol: config BRCMFMAC_SDIO bool "SDIO bus interface support for FullMAC driver" depends on MMC allows BRCMFMAC_SDIO to be y even when MMC=m.

The cw1200_spi driver tries to mirror the cw1200_sdio driver's lock API, which relies on sdio_claim_host/sdio_release_host to serialize hardware operations across multiple threads. Unfortunately the implementation was flawed, as it lacked a way to wake up the lock requestor when there was contention, often resulting in a hang. This problem was uncovered while trying to fix the spi-transfers-in-interrupt-context BUG() corrected in the previous patch. Many thanks to Dave Sizeburns for his assistance in fixing this.

When we get an interrupt from the hardware, the first thing the driver does is tell the device to mask off the interrupt line. Unfortunately this involves a SPI transaction in interrupt context. Some (most?) SPI controllers perform the transfer asynchronously and try to sleep. This is bad, and triggers a BUG(). So, work around this by using adding a hwbus hook for the cw1200 driver core to call. The cw1200_spi driver translates this into irq_disable()/irq_enable() calls instead, which can safely be called in interrupt context. Apparently the platforms I used to develop the cw1200_spi driver used synchronous spi_sync() implementations, which is why this didn't surface until now. Many thanks to Dave Sizeburns for the inital bug report and his services as a tester. Signed-off-by:

The only actual current lockref user (dcache) uses zero reference counts even for perfectly live dentries, because it's a cache: there may not be any users, but that doesn't mean that we want to throw away the dentry. At the same time, the dentry cache does have a notion of a truly "dead" dentry that we must not even increment the reference count of, because we have pruned it and it is not valid. Currently that distinction is not visible in the lockref itself, and the dentry cache validation uses "lockref_get_or_lock()" to either get a new reference to a dentry that already had existing references (and thus cannot be dead), or get the dentry lock so that we can then verify the dentry and increment the reference count under the lock if that verification was successful. That's all somewhat complicated. This adds the concept of being "dead" to the lockref itself, by simply using a count that is negative. This allows a usage scenario where we can increment the refcount of a dentry without having to validate it, and pushing the special "we killed it" case into the lockref code. The dentry code itself doesn't actually use this yet, and it's probably too late in the merge window to do that code (the dentry_kill() code with its "should I decrement the count" logic really is pretty complex code), but let's introduce the concept at the lockref level now.

This reverts commits 61e00655, 73f8645d and 8e22ecb6: "Input: introduce BTN/ABS bits for drums and guitars" "HID: wiimote: add support for Guitar-Hero drums" "HID: wiimote: add support for Guitar-Hero guitars" The extra new ABS_xx values resulted in ABS_MAX no longer being a power-of-two, which broke the comparison logic. It also caused the ioctl numbers to overflow into the next byte, causing problems for that. We'll try again for 3.13. Reported-by:

TCP receive window handling is multi staged. A socket has a memory budget, static or dynamic, in sk_rcvbuf. Because we do not really know how this memory budget translates to a TCP window (payload), TCP announces a small initial window (about 20 MSS). When a packet is received, we increase TCP rcv_win depending on the payload/truesize ratio of this packet. Good citizen packets give a hint that it's reasonable to have rcv_win = sk_rcvbuf/2 This heuristic takes place in tcp_grow_window() Problem is : We currently call tcp_grow_window() only for in-order packets. This means that reorders or packet losses stop proper grow of rcv_win, and senders are unable to benefit from fast recovery, or proper reordering level detection. Really, a packet being stored in OFO queue is not a bad citizen. It should be part of the game as in-order packets. In our traces, we very often see sender is limited by linux small receive windows, even if linux hosts use autotuning (DRS) and should allow rcv_win to grow to ~3MB. Signed-off-by:

Commit c0a77ec7 'bnx2x: Add missing braces in bnx2x:bnx2x_link_initialize' identified indentation problem, but resolved it by adding braces instead of fixing the indentation. The braces now prevents a config_init call in some cases, though it should be called regardless of that condition. This patch removes the braces and fix the confusing indentation that caused this mess. Signed-off-by:

In commit 0f7cc9a3 "tcp: increase throughput when reordering is high", it only allows cwnd to increase in Open state. This mistakenly disables slow start after timeout (CA_Loss). Moreover cwnd won't grow if the state moves from Disorder to Open later in tcp_fastretrans_alert(). Therefore the correct logic should be to allow cwnd to grow as long as the data is received in order in Open, Loss, or even Disorder state. Signed-off-by:
