2019-09-11swiotlb: Split size parameter to map/unmap APIsLu Baolu
This splits the size parameter to swiotlb_tbl_map_single() and swiotlb_tbl_unmap_single() into an alloc_size and a mapping_size parameter, where the latter one is rounded up to the iommu page size.

2019-09-11regulator: core: Fix error return for /sys accessH. Nikolaus Schaller
regulator_uV_show() is missing error handling if regulator_get_voltage_rdev() returns negative values. Instead it prints the errno as a string, e.g. -EINVAL as "-22" which could be interpreted as -22 µV. We also do not need to hold the lock while converting the integer to a string.

2019-09-11gpio: aspeed: Add in ast2600 details to Aspeed driverRashmica Gupta
The ast2600 is a new generation of SoC from ASPEED. Similarly to the ast2400 and ast2500, it has a GPIO controller for it's 3.3V GPIO pins. Additionally, it has a GPIO controller for 1.8V GPIO pins. As the register names for both controllers are the same and the 36 1.8V GPIOs and the first 36 of the 3.3V GPIOs are all bidirectional, we can use the same configuration struct and use the ngpio property to differentiate between the two sets of GPIOs.

2019-09-11gpiolib: acpi: Add gpiolib_acpi_run_edge_events_on_boot option and blacklistHans de Goede
Another day; another DSDT bug we need to workaround... Since commit ca876c7483b6 ("gpiolib-acpi: make sure we trigger edge events at least once on boot") we call _AEI edge handlers at boot. In some rare cases this causes problems. One example of this is the Minix Neo Z83-4 mini PC, this device has a clear DSDT bug where it has some copy and pasted code for dealing with Micro USB-B connector host/device role switching, while the mini PC does not even have a micro-USB connector. This code, which should not be there, messes with the DDC data pin from the HDMI connector (switching it to GPIO mode) breaking HDMI support. To avoid problems like this, this commit adds a new gpiolib_acpi.run_edge_events_on_boot kernel commandline option, which allows disabling the running of _AEI edge event handlers at boot. The default value is -1/auto which uses a DMI based blacklist, the initial version of this blacklist contains the Neo Z83-4 fixing the HDMI breakage.

2019-09-11cfg80211: Purge frame registrations on iftype changeDenis Kenzior
Currently frame registrations are not purged, even when changing the interface type. This can lead to potentially weird situations where frames possibly not allowed on a given interface type remain registered due to the type switching happening after registration. The kernel currently relies on userspace apps to actually purge the registrations themselves, this is not something that the kernel should rely on. Add a call to cfg80211_mlme_purge_registrations() to forcefully remove any registrations left over prior to switching the iftype.

Then, if we have shared state, this may not be reset properly, causing problems; for example, we saw a case where aggregation sessions weren't removed properly (due to the TX start being offloaded to firmware and it relying on deauth for stop), causing a lot of traffic to get lost due to the SN reset after remove/add of the peer.

2019-09-11mac80211: clear crypto tx tailroom counter upon keys enableLior Cohen
In case we got a fw restart while roaming from encrypted AP to non-encrypted one, we might end up with hitting a warning on the pending counter crypto_tx_tailroom_pending_dec having a non-zero value. The following comment taken from net/mac80211/key.c explains the rational for the delayed tailroom needed: /* * The reason for the delayed tailroom needed decrementing is to * make roaming faster: during roaming, all keys are first deleted * and then new keys are installed. The first new key causes the * crypto_tx_tailroom_needed_cnt to go from 0 to 1, which invokes * the cost of synchronize_net() (which can be slow). Avoid this * by deferring the crypto_tx_tailroom_needed_cnt decrementing on * key removal for a while, so if we roam the value is larger than * zero and no 0->1 transition happens. * * The cost is that if the AP switching was from an AP with keys * to one without, we still allocate tailroom while it would no * longer be needed. However, in the typical (fast) roaming case * within an ESS this usually won't happen. */ The next flow lead to the warning eventually reported as a bug: 1. Disconnect from encrypted AP 2. Set crypto_tx_tailroom_pending_dec = 1 for the key 3. Schedule work 4. Reconnect to non-encrypted AP 5. Add a new key, setting the tailroom counter = 1 6. Got FW restart while pending counter is set ---> hit the warning While on it, the ieee80211_reset_crypto_tx_tailroom() func was merged into its single caller ieee80211_reenable_keys (previously called ieee80211_enable_keys). Also, we reset the crypto_tx_tailroom_pending_dec and remove the counters warning as we just reset both.

2019-09-11mac80211: list features in WEP/TKIP disable in better orderJohannes Berg
"HE/HT/VHT" is a bit confusing since really the order of development (and possible support) is different - change this to "HT/VHT/HE".

2019-09-11cfg80211: always shut down on HW rfkillJohannes Berg
When the RFKILL subsystem isn't available, then rfkill_blocked() always returns false. In the case of hardware rfkill this will be wrong though, as if the hardware reported being killed then it cannot operate any longer. Since we only ever call the rfkill_sync work in this case, just rename it to rfkill_block and always pass "true" for the blocked parameter, rather than passing rfkill_blocked(). We rely on the underlying driver to still reject any new attempt to bring up the device by itself.

2019-09-10scsi: hisi_sas: Fix the conflict between device gone and host resetXiang Chen
When device gone, it will check whether it is during reset, if not, it will send internal task abort. Before internal task abort returned, reset begins, and it will check whether SAS_PHY_UNUSED is set, if not, it will call hisi_sas_init_device(), but at that time domain_device may already be freed or part of it is freed, so it may referenece null pointer in hisi_sas_init_device(). It may occur as follows: thread0 thread1 hisi_sas_dev_gone() check whether in RESET(no) internal task abort reset prep soft_reset ... (part of reset_done) internal task abort failed release resource anyway clear_itct device->lldd_dev=NULL hisi_sas_reset_init_all_device check sas_dev->dev_type is SAS_PHY_UNUSED and !device set dev_type SAS_PHY_UNUSED sas_free_device hisi_sas_init_device ... Semaphore hisi_hba.sema is used to sync the processes of device gone and host reset. To solve the issue, expand the scope that semaphore protects and let them never occur together. And also some places will check whether domain_device is NULL to judge whether the device is gone. So when device gone, need to clear sas_dev->sas_device.

Add BIST (built in self test) support for phy loopback. Through the new debugfs interface, the user can configure loopback mode/linkrate/phy id/code mode before enabling it. And also user can enable/disable BIST function.
