2019-02-27staging: fsl-dpaa2: ethsw: Handle SWITCHDEV_PORT_ATTR_SETFlorian Fainelli
Following patches will change the way we communicate setting a port's attribute and use a blocking notifier to perform those tasks. Prepare ethsw to support receiving notifier events targeting SWITCHDEV_PORT_ATTR_SET and simply translate that into the existing swdev_port_attr_set() call.

2019-02-27net: phy: Micrel KSZ8061: link failure after cable connectRajasingh Thavamani
With Micrel KSZ8061 PHY, the link may occasionally not come up after Ethernet cable connect. The vendor's (Microchip, former Micrel) errata sheet 80000688A.pdf descripes the problem and possible workarounds in detail, see below. The batch implements workaround 1, which permanently fixes the issue. DESCRIPTION Link-up may not occur properly when the Ethernet cable is initially connected. This issue occurs more commonly when the cable is connected slowly, but it may occur any time a cable is connected. This issue occurs in the auto-negotiation circuit, and will not occur if auto-negotiation is disabled (which requires that the two link partners be set to the same speed and duplex). END USER IMPLICATIONS When this issue occurs, link is not established. Subsequent cable plug/unplaug cycle will not correct the issue. WORk AROUND There are four approaches to work around this issue: 1. This issue can be prevented by setting bit 15 in MMD device address 1, register 2, prior to connecting the cable or prior to setting the Restart Auto-negotiation bit in register 0h. The MMD registers are accessed via the indirect access registers Dh and Eh, or via the Micrel EthUtil utility as shown here: . if using the EthUtil utility (usually with a Micrel KSZ8061 Evaluation Board), type the following commands: > address 1 > mmd 1 > iw 2 b61a . Alternatively, write the following registers to write to the indirect MMD register: Write register Dh, data 0001h Write register Eh, data 0002h Write register Dh, data 4001h Write register Eh, data B61Ah 2. The issue can be avoided by disabling auto-negotiation in the KSZ8061, either by the strapping option, or by clearing bit 12 in register 0h. Care must be taken to ensure that the KSZ8061 and the link partner will link with the same speed and duplex. Note that the KSZ8061 defaults to full-duplex when auto-negotiation is off, but other devices may default to half-duplex in the event of failed auto-negotiation. 3. The issue can be avoided by connecting the cable prior to powering-up or resetting the KSZ8061, and leaving it plugged in thereafter. 4. If the above measures are not taken and the problem occurs, link can be recovered by setting the Restart Auto-Negotiation bit in register 0h, or by resetting or power cycling the device. Reset may be either hardware reset or software reset (register 0h, bit 15). PLAN This errata will not be corrected in the future revision.

2019-02-27bnxt_en: Drop oversize TX packets to prevent errors.Michael Chan
There have been reports of oversize UDP packets being sent to the driver to be transmitted, causing error conditions. The issue is likely caused by the dst of the SKB switching between 'lo' with 64K MTU and the hardware device with a smaller MTU. Patches are being proposed by Mahesh Bandewar <maheshb@google.com> to fix the issue. In the meantime, add a quick length check in the driver to prevent the error. The driver uses the TX packet size as index to look up an array to setup the TX BD. The array is large enough to support all MTU sizes supported by the driver. The oversize TX packet causes the driver to index beyond the array and put garbage values into the TX BD. Add a simple check to prevent this.

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().

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.

WCN3990 firmware versions WLAN.HL.2.0-01617-QCAHLSWMTPLZ-1 & onwards supports maximum 33 peers including self peer. To support maximum peers, send updated peer param to firmware during initialization.

2019-02-26ath10k: remove the calibration data fetch for sdioWen Gong
The calibration data fetch will trigger sdio error, then sdio will become fail untill reboot system. If happens when run ifconfig wlan down, then ifconfig wlan up will fail untill reboot system.Remove it fix the ifconfig wlan issue. Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00005-QCARMSWP-1. Signed-off-by: Wen Gong <wgong@codeaurora.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2019-02-26ath10k: Fix length of wmi tlv command for protected mgmt framesSurabhi Vishnoi
The length of wmi tlv command for management tx send is calculated incorrectly in case of protected management frames as there is addition of IEEE80211_CCMP_MIC_LEN twice. This leads to improper behaviour of firmware as the wmi tlv mgmt tx send command for protected mgmt frames is formed wrongly. Fix the length calculation of wmi tlv command for mgmt tx send in case of protected management frames by adding the IEEE80211_CCMP_MIC_LEN only once. Tested HW: WCN3990 Tested FW: WLAN.HL.3.1-00784-QCAHLSWMTPLZ-1 Fixes: 1807da49733e "ath10k: wmi: add management tx by reference support over wmi" Signed-off-by: Surabhi Vishnoi <svishnoi@codeaurora.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2019-02-26ath10k: don't report unset rssi values to mac80211Alagu Sankar
The SDIO firmware does not provide RSSI value to the host, it's only set to zero. In that case don't report the value to mac80211. 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.
