2020-03-26ata: make SATA_PMP option selectable only if any SATA host driver is enabledBartlomiej Zolnierkiewicz
There is no reason to expose SATA_PMP config option when no SATA host drivers are enabled. To fix it add SATA_HOST config option, make all SATA host drivers select it and finally make SATA_PMP config options depend on it. This also serves as preparation for the future changes which optimize libata core code size on PATA only setups. CC: "James E.J. Bottomley" <jejb@linux.ibm.com> Reviewed-by: Martin K.

2020-03-26staging: wilc1000: Use crc7 in lib/ rather than a private copyGeorge Spelvin
The code in lib/ is the desired polynomial, and even includes the 1-bit left shift in the table rather than needing to code it explicitly. While I'm in Kconfig, add a description of what a WILC1000 is. Kconfig questions that require me to look up a data sheet to find out that I probably don't have one are a pet peeve.

2020-03-26mac80211: mark station unauthorized before key removalJohannes Berg
If a station is still marked as authorized, mark it as no longer so before removing its keys.

2020-03-26mac80211: Check port authorization in the ieee80211_tx_dequeue() caseJouni Malinen
mac80211 used to check port authorization in the Data frame enqueue case when going through start_xmit(). However, that authorization status may change while the frame is waiting in a queue. Add a similar check in the dequeue case to avoid sending previously accepted frames after authorization change. This provides additional protection against potential leaking of frames after a station has been disconnected and the keys for it are being removed.

2020-03-26mac80211: drop data frames without key on encrypted linksJohannes Berg
If we know that we have an encrypted link (based on having had a key configured for TX in the past) then drop all data frames in the key selection handler if there's no key anymore. This fixes an issue with mac80211 internal TXQs - there we can buffer frames for an encrypted link, but then if the key is no longer there when they're dequeued, the frames are sent without encryption. This happens if a station is disconnected while the frames are still on the TXQ. Detecting that a link should be encrypted based on a first key having been configured for TX is fine as there are no use cases for a connection going from with encryption to no encryption. With extended key IDs, however, there is a case of having a key configured for only decryption, so we can't just trigger this behaviour on a key being configured.

The original single target IPI fastpath patch forgot to filter the ICR destination shorthand field. Multicast IPI is not suitable for this feature since wakeup the multiple sleeping vCPUs will extend the interrupt disabled time, it especially worse in the over-subscribe and VM has a little bit more vCPUs scenario. Let's narrow it down to single target IPI. Two VMs, each is 76 vCPUs, one running 'ebizzy -M', the other running cyclictest on all vCPUs, w/ this patch, the avg score of cyclictest can improve more than 5%.

2020-03-26nvme: Fix controller creation races with teardown flowIsrael Rukshin
Calling nvme_sysfs_delete() when the controller is in the middle of creation may cause several bugs. If the controller is in NEW state we remove delete_controller file and don't delete the controller. The user will not be able to use nvme disconnect command on that controller again, although the controller may be active. Other bugs may happen if the controller is in the middle of create_ctrl callback and nvme_do_delete_ctrl() starts. For example, freeing I/O tagset at nvme_do_delete_ctrl() before it was allocated at create_ctrl callback. To fix all those races don't allow the user to delete the controller before it was fully created.

2020-03-26nvme: Make nvme_uninit_ctrl symmetric to nvme_init_ctrlIsrael Rukshin
Put the ctrl reference count at nvme_uninit_ctrl as opposed to nvme_init_ctrl which takes it. This decrease the reference count at the core layer instead of decreasing it on each transport separately. Also move the call of nvme_uninit_ctrl at PCI driver after calling to nvme_release_prp_pools and nvme_dev_unmap, in order to put the reference count after using the dev. This is safe because those functions use nvme_dev which is freed only later at nvme_pci_free_ctrl.

2020-03-26nvme: Fix ctrl use-after-free during sysfs deletionIsrael Rukshin
In case nvme_sysfs_delete() is called by the user before taking the ctrl reference count, the ctrl may be freed during the creation and cause the bug. Take the reference as soon as the controller is externally visible, which is done by cdev_device_add() in nvme_init_ctrl(). Also take the reference count at the core layer instead of taking it on each transport separately.
