2019-10-09iwlwifi: pcie: change qu with jf devices to use qu configurationLuca Coelho
There were a bunch of devices with qu and jf that were loading the configuration with pu and jf, which is wrong. Fix them all accordingly. Additionally, remove 0x1010 and 0x1210 subsytem IDs from the list, since they are obviously wrong, and 0x0044 and 0x0244, which were duplicate.

2019-10-09iwlwifi: exclude GEO SAR support for 3168Luca Coelho

2019-10-09iwlwifi: pcie: fix memory leaks in iwl_pcie_ctxt_info_gen3_initNavid Emamdoost
In iwl_pcie_ctxt_info_gen3_init there are cases that the allocated dma memory is leaked in case of error. DMA memories prph_scratch, prph_info, and ctxt_info_gen3 are allocated and initialized to be later assigned to trans_pcie. But in any error case before such assignment the allocated memories should be released. First of such error cases happens when iwl_pcie_init_fw_sec fails. Current implementation correctly releases prph_scratch. But in two sunsequent error cases where dma_alloc_coherent may fail, such releases are missing. This commit adds release for prph_scratch when allocation for prph_info fails, and adds releases for prph_scratch and prph_info when allocation for ctxt_info_gen3 fails.

2019-10-09iwlwifi: pcie: fix indexing in command dump for new HWJohannes Berg
We got a crash in iwl_trans_pcie_get_cmdlen(), while the TFD was being accessed to sum up the lengths. We want to access the TFD here, which is the information for the hardware. We always only allocate 32 buffers for the cmd queue, but on newer hardware (using TFH) we can also allocate only a shorter hardware array, also only 32 TFDs. Prior to the TFH, we had to allocate a bigger TFD array but would make those point to a smaller set of buffers. Additionally, now max_tfd_queue_size is up to 65536, so we can access *way* out of bounds of a really only 32-entry array, so it crashes. Fix this by making the TFD index depend on which hardware we are using right now. While changing the calculation, also fix it to not use void ptr arithmetic, but cast to u8 * before.

2019-10-09iwlwifi: mvm: fix race in sync rx queue notificationNaftali Goldstein
Consider the following flow: 1. Driver starts to sync the rx queues due to a delba. mvm->queue_sync_cookie=1. This rx-queues-sync is synchronous, so it doesn't increment the cookie until all rx queues handle the notification from FW. 2. During this time, driver starts to sync rx queues due to nssn sync required. The cookie's value is still 1, but it doesn't matter since this rx-queue-sync is non-synchronous so in the notification handler the cookie is ignored. What _does_ matter is that this flow increments the cookie to 2 immediately. Remember though that the FW won't start servicing this command until it's done with the previous one. 3. FW is still handling the first command, so it sends a notification with internal_notif->sync=1, and internal_notif->cookie=0, which triggers a WARN_ONCE. The solution for this race is to only use the mvm->queue_sync_cookie in case of a synchronous sync-rx-queues. This way in step 2 the cookie's value won't change so we avoid the WARN. The commit in the "fixes" field is the first commit to introduce non-synchronous sending of this command to FW.

2019-10-09iwlwifi: mvm: force single phy initHaim Dreyfuss
The PHY is initialized during device initialization, but devices with the tx_siso_diversity flag set need to send PHY_CONFIGURATION_CMD first, otherwise the PHY would be reinitialized, causing a SYSASSERT. To fix this, use a bit that tells the FW not to complete the PHY initialization before a PHY_CONFIGURATION_CMD is received.

2019-10-09iwlwifi: fix ACPI table revision checksLuca Coelho
We can't check for the ACPI table revision validity in the same if where we check if the package was read correctly, because we return PTR_ERR(pkg) and if the table is not valid but the pointer is, we would return a valid pointer as an error.

2019-10-04net: phy: at803x: use operating parameters from PHY-specific statusRussell King
Read the PHY-specific status register for the current operating mode (speed and duplex) of the PHY. This register reflects the actual mode that the PHY has resolved depending on either the advertisements of autoneg is enabled, or the forced mode if autoneg is disabled. This ensures that phylib's software state always tracks the hardware state. It seems both AR8033 (which uses the AR8031 ID) and AR8035 support this status register. AR8030 is not known at the present time. This patch depends on "net: phy: extract pause mode" and "net: phy: extract link partner advertisement reading".

2019-10-04net: phy: allow for reset line to be tied to a sleepy GPIO controllerAndrea Merello
mdio_device_reset() makes use of the atomic-pretending API flavor for handling the PHY reset GPIO line. I found no hint that mdio_device_reset() is called from atomic context and indeed it uses usleep_range() since long time, so I would assume that it is OK to sleep there. This patch switch to gpiod_set_value_cansleep() in mdio_device_reset(). This is relevant if e.g. the PHY reset line is tied to a I2C GPIO controller. This has been tested on a ZynqMP board running an upstream 4.19 kernel and then hand-ported on current kernel tree.

While MR uses live as the SRCU 'update', the MW case uses the xarray directly, xa_erase() causes the MW to become inaccessible to the pagefault thread. Thus whenever a MW is removed from the xarray we must synchronize_srcu() before freeing it. This must be done before freeing the mkey as re-use of the mkey while the pagefault thread is using the stale mkey is undesirable.

2019-10-02net: dsa: rtl8366: Check VLAN ID and not portsLinus Walleij
There has been some confusion between the port number and the VLAN ID in this driver. What we need to check for validity is the VLAN ID, nothing else. The current confusion came from assigning a few default VLANs for default routing and we need to rewrite that properly. Instead of checking if the port number is a valid VLAN ID, check the actual VLAN IDs passed in to the callback one by one as expected.

2019-10-01xen-netfront: do not use ~0U as error return value for xennet_fill_frags()Dongli Zhang
xennet_fill_frags() uses ~0U as return value when the sk_buff is not able to cache extra fragments. This is incorrect because the return type of xennet_fill_frags() is RING_IDX and 0xffffffff is an expected value for ring buffer index. In the situation when the rsp_cons is approaching 0xffffffff, the return value of xennet_fill_frags() may become 0xffffffff which xennet_poll() (the caller) would regard as error. As a result, queue->rx.rsp_cons is set incorrectly because it is updated only when there is error. If there is no error, xennet_poll() would be responsible to update queue->rx.rsp_cons. Finally, queue->rx.rsp_cons would point to the rx ring buffer entries whose queue->rx_skbs[i] and queue->grant_rx_ref[i] are already cleared to NULL. This leads to NULL pointer access in the next iteration to process rx ring buffer entries. The symptom is similar to the one fixed in commit 00b368502d18 ("xen-netfront: do not assume sk_buff_head list is empty in error handling"). This patch changes the return type of xennet_fill_frags() to indicate whether it is successful or failed. The queue->rx.rsp_cons will be always updated inside this function.

Commit b6b6cc9acd7b, changed the call to dwxgmac2_rss_write_reg() passing it the variable cfg->key[i]. As key is an u8 but we write 32 bits at a time we need to cast it into an u32 so that the correct key values are written.
