2019-02-27Bluetooth: hci_qca: Move boot delay to qca_send_power_pulse()Matthias Kaehlcke
After sending a power on pulse the driver has a delay of 100ms to allow the host controller to boot. Move the delay into qca_send_power_pulse(), since it is directly related with the power-on pulse.

2019-02-26tipc: fix race condition causing hung sendtoTung Nguyen
When sending multicast messages via blocking socket, if sending link is congested (tsk->cong_link_cnt is set to 1), the sending thread will be put into sleeping state. However, tipc_sk_filter_rcv() is called under socket spin lock but tipc_wait_for_cond() is not. So, there is no guarantee that the setting of tsk->cong_link_cnt to 0 in tipc_sk_proto_rcv() in CPU-1 will be perceived by CPU-0. If that is the case, the sending thread in CPU-0 after being waken up, will continue to see tsk->cong_link_cnt as 1 and put the sending thread into sleeping state again. The sending thread will sleep forever. CPU-0 | CPU-1 tipc_wait_for_cond() | { | // condition_ = !tsk->cong_link_cnt | while ((rc_ = !(condition_))) { | ... | release_sock(sk_); | wait_woken(); | | if (!sock_owned_by_user(sk)) | tipc_sk_filter_rcv() | { | ... | tipc_sk_proto_rcv() | { | ... | tsk->cong_link_cnt--; | ... | sk->sk_write_space(sk); | ... | } | ... | } sched_annotate_sleep(); | lock_sock(sk_); | remove_wait_queue(); | } | } | This commit fixes it by adding memory barrier to tipc_sk_proto_rcv() and tipc_wait_for_cond().

2019-02-26s390/cio: Use cpa range elsewhere within vfio-ccwEric Farman

2019-02-26s390/cio: Fix vfio-ccw handling of recursive TICsEric Farman
The routine ccwchain_calc_length() is tasked with looking at a channel program, seeing how many CCWs are chained together by the presence of the Chain-Command flag, and returning a count to the caller. Previously, it also considered a Transfer-in-Channel CCW as being an appropriate mechanism for chaining. The problem at the time was that the TIC CCW will almost certainly not go to the next CCW in memory (because the CC flag would be sufficient), and so advancing to the next 8 bytes will cause us to read potentially invalid memory. So that comparison was removed, and the target of the TIC is processed as a new chain. This is fine when a TIC goes to a new chain (consider a NOP+TIC to a channel program that is being redriven), but there is another scenario where this falls apart. A TIC can be used to "rewind" a channel program, for example to find a particular record on a disk with various orientation CCWs. In this case, we DO want to consider the memory after the TIC since the TIC will be skipped once the requested criteria is met. This is due to the Status Modifier presented by the device, though software doesn't need to operate on it beyond understanding the behavior change of how the channel program is executed. So to handle this, we will re-introduce the check for a TIC CCW but limit it by examining the target of the TIC. If the TIC doesn't go back into the current chain, then current behavior applies; we should stop counting CCWs and let the target of the TIC be handled as a new chain. But, if the TIC DOES go back into the current chain, then we need to keep looking at the memory after the TIC for when the channel breaks out of the TIC loop. We can't use tic_target_chain_exists() because the chain in question hasn't been built yet, so we will redefine that comparison with some small functions to make it more readable and to permit refactoring later.

Jakub Kicinski says: ==================== devlink: make ethtool compat reliable This is a follow up to the series which added device flash updates via devlink. I went with the approach of adding a new NDO in the end. It seems to end up looking cleaner. First patch removes the option to build devlink as a module. Users can still decide to not build it, but the module option ends up not being worth the maintenance cost. Next two patches add a NDO which can be used to ask the driver to return a devlink instance associated with a given netdev, instead of iterating over devlink ports. Drivers which implement this NDO must take into account the potential impact on the visibility of the devlink instance. With the new NDO in place we can remove NFP ethtool flash update code. Fifth patch makes sure we hold a reference to dev while callbacks are active. Last but not least the NULL-check of devlink->ops is moved to instance allocation time. Last but not least missing checks for devlink->ops are added. There is currently no driver registering devlink without ops, so can just fix this in -next. v2 (Michal): add netdev_to_devlink() in patch 3. v3 (Florian): - add missing checks for devlink->ops; - move locking/holding into devlink_compat_ functions. v4 (Jiri): - hold devlink_mutex around callbacks (patch 2); - require non-NULL ops (patch 6). ==================== Signed-off-by: David S.

One risk here is that value zero might be a valid value with other firmware, currently there's no way to detect that. Without the fix, the rssi value indicated by iw changes between the actual value and -95. Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00005-QCARMSWP-1.

2019-02-26ath10k: sdio: reset chip on power_down()Wen Gong
The target device needs to be reset during power_down(), otherwise only the first power_up() will work. And as ath10k calls power_up() during driver initialisation the driver would be otherwise unusable. Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00005-QCARMSWP-1.

2019-02-26ath10k: sdio: disable fwlog printsAlagu Sankar
The SDIO firmware may turn it on based on scratch registers so disable the firmware log to avoid that.

2019-02-26ath10k: sdio: set hi_acs_flagsAlagu Sankar
The SDIO firmware does not allow transmitting packets with the reduced tx completion HI_ACS option. SDIO firmware uses 1544 as alternate credit size, which is not big enough for the maximum sized mac80211 frames. Disable both these HI_ACS flags for SDIO.
