2019-07-29MAINTAINERS: Remove mailing-list entry for XDP (eXpress Data Path)Jesper Dangaard Brouer
This removes the mailing list xdp-newbies@vger.kernel.org from the XDP kernel maintainers entry. Being in the kernel MAINTAINERS file successfully caused the list to receive kbuild bot warnings, syzbot reports and sometimes developer patches. The level of details in these messages, doesn't match the target audience of the XDP-newbies list. This is based on a survey on the mailing list, where 73% voted for removal from MAINTAINERS file.

2019-07-29dax: Fix missed wakeup in put_unlocked_entry()Jan Kara
The condition checking whether put_unlocked_entry() needs to wake up following waiter got broken by commit 23c84eb78375 ("dax: Fix missed wakeup with PMD faults"). We need to wake the waiter whenever the passed entry is valid (i.e., non-NULL and not special conflict entry). This could lead to processes never being woken up when waiting for entry lock.

Andy Shevchenko says: ==================== NFC: nxp-nci: clean up and new device support Few people reported that some laptops are coming with new ACPI ID for the devices should be supported by nxp-nci driver. This series adds new ID (patch 2), cleans up the driver from legacy platform data and unifies GPIO request for Device Tree and ACPI (patches 3-6), removes dead or unneeded code (patches 7, 9, 11), constifies ID table (patch 8), removes comma in terminator line for better maintenance (patch 10) and rectifies Kconfig entry (patches 12-14). It also contains a fix for NFC subsystem as suggested by Sedat. Series has been tested by Sedat.

Currently, hclge_reset_err_handle() will assert a global reset when the failing count is smaller than MAX_RESET_FAIL_CNT, which will affect other running functions. So this patch removes this upgrading, and uses re-scheduling reset task to do it.

For some cases, ops->get_reset_level may not be implemented, so we should check whether it is NULL before calling get_reset_level. Signed-off-by: Guangbin Huang <huangguangbin@huawei.com> Signed-off-by: Huazhong Tan <tanhuazhong@huawei.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-07-29net: hns3: add reset checking before set channelsJian Shen
hns3_set_channels() should check the resetting status firstly, since the device will reinitialize when resetting. If the reset has not completed, the hns3_set_channels() may access invalid memory.

2019-07-29pidfd: Add warning if exit_state is 0 during notificationJoel Fernandes (Google)
Previously a condition got missed where the pidfd waiters are awakened before the exit_state gets set. This can result in a missed notification [1] and the polling thread waiting forever. It is fixed now, however it would be nice to avoid this kind of issue going unnoticed in the future. So just add a warning to catch it in the future. /* References */ [1]: https://lore.kernel.org/lkml/20190717172100.261204-1-joel@joelfernandes.org/ Signed-off-by: Joel Fernandes (Google) <joel@joelfernandes.org> Link: https://lore.kernel.org/r/20190724164816.201099-1-joel@joelfernandes.org Signed-off-by: Christian Brauner <christian@brauner.io>

2019-07-29mac80211: add support for the ADDBA extension elementJohn Crispin
HE allows peers to negotiate the aggregation fragmentation level to be used during transmission. The level can be 1-3. The Ext element is added behind the ADDBA request inside the action frame. The responder will then reply with the same level or a lower one if the requested one is not supported. This patch only handles the negotiation part as the ADDBA frames get passed to the ATH11k firmware, which does the rest of the magic for us aswell as generating the requests.
