2019-06-14mac80211: call rate_control_send_low() internallyJohannes Berg
There's no rate control algorithm that *doesn't* want to call it internally, and calling it internally will let us modify its behaviour in the future. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2019-06-14nl80211: require and validate vendor command policyJohannes Berg
Require that each vendor command give a policy of its sub-attributes in NL80211_ATTR_VENDOR_DATA, and then (stricly) check the contents, including the NLA_F_NESTED flag that we couldn't check on the outer layer because there we don't know yet. It is possible to use VENDOR_CMD_RAW_DATA for raw data, but then no nested data can be given (NLA_F_NESTED flag must be clear) and the data is just passed as is to the command.

2019-06-13r8169: let mdio read functions return -ETIMEDOUTHeiner Kallweit
In case of a timeout currently ~0 is returned. Callers often just check whether a certain bit is set and therefore may behave incorrectly. So let's return -ETIMEDOUT in case of a timeout. r8168_phy_ocp_read is used in r8168g_mdio_read only, therefore we can apply the same change.

2019-06-13s390/qeth: allocate a single cmd on read channelJulian Wiedmann
We statically allocate 8 cmd buffers on the read channel, when the only IO left that's still using them is the long-running READ. Replace this with a single allocated cmd, that gets restarted whenever the READ completed. This introduces refcounting for allocated cmds, so that the READ cmd can survive the IO completion.

2019-06-13s390/qeth: command-chain the IDX sequenceJulian Wiedmann
The current IDX sequence first sends one WRITE cmd to activate the device, and then sends a second cmd that READs the response. Using qeth_alloc_cmd(), we can combine this into a single IO with two command-chained CCWs. Signed-off-by: Julian Wiedmann <jwi@linux.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-06-13s390/qeth: convert RCD code to common IO infrastructureJulian Wiedmann
The RCD code is the last remaining IO path that doesn't use the qeth_send_control_data() infrastructure. Doing so allows us to remove all sorts of custom state machinery and logic in the IRQ handler. Instead of introducing statically allocated cmd buffers for this single IO on the data channel, use the new qeth_alloc_cmd() helper.

2019-06-13s390/qeth: add support for dynamically allocated cmdsJulian Wiedmann
qeth currently uses a fixed set of statically allocated cmd buffers for the read and write IO channels. This (1) doesn't play well with the single RCD cmd we need to issue on the data channel, (2) doesn't provide the necessary flexibility for certain IDX improvements, and (3) is also rather wasteful since the buffers are idle most of the time. Add a new type of cmd buffer that is dynamically allocated, and keeps its ccw chain in the DMA data area. Since this touches most callers of qeth_setup_ccw(), also add a new CCW flags parameter for future usage. Signed-off-by: Julian Wiedmann <jwi@linux.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-06-13s390/qeth: remove 'channel' parameter from callbacksJulian Wiedmann
Each cmd buffer maintains a pointer to the IO channel that it was/will be issued on. So when dealing with cmd buffers, we don't need to pass around a separate channel pointer. Signed-off-by: Julian Wiedmann <jwi@linux.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-06-13s390/qeth: convert device-specific trace entriesJulian Wiedmann

Miller <davem@davemloft.net>
2019-06-13s390/qeth: remove OSN-specific IO codeJulian Wiedmann
OSN currently provides a custom code path to submit IPA cmds, without waiting for the cmd response. Replace it with qeth_send_ipa_cmd(), which uses the common qeth_send_control_data() IO infrastructure. By setting a custom iob->callback, we can now provide feedback to the caller about whether the cmd has been successfully submitted to HW. Since the callback then immediately wakes up the reply-waiter object, we maintain the old behaviour of returning early without waiting for the response.

2019-06-13s390/qeth: remove qeth_wait_for_buffer()Julian Wiedmann
The basic MPC initialization sequence is strictly sequential, and waiting for an available cmd buffer should never be necessary. So this change only affects the OSN path, where dangling waiters on an unbounded wait_event() are not desirable. Switch to qeth_get_buffers(), and let OSN callers deal with -ENOMEM.

2019-06-13s390/qeth: clean up setting of BLKT defaultsJulian Wiedmann
When called from qeth_core_probe_device(), qeth_determine_capabilities() initializes the device's BLKT defaults. From all other callers, the ccw_device has already been set online and the BLKT setting is skipped. Clean this up by extracting the BLKT setting into a separate helper that gets called from the right place. Signed-off-by: Julian Wiedmann <jwi@linux.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-06-13s390/qeth: restart pending READ cmd from callbackJulian Wiedmann
The completion of a pending READ cmd is processed via qeth_issue_next_read_cb(). Let this callback also start the next READ cmd, instead of hardcoding that step into the IRQ handler. While at it remove the check of the channel state, __qeth_issue_next_read() already does this. Signed-off-by: Julian Wiedmann <jwi@linux.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-06-13s390/qeth: simplify DOWN state handlingJulian Wiedmann
When the tear down sequence in qeth_l?_stop_card() has finished, the card is guaranteed to be in DOWN state and we don't have to check for it again. With this insight we can also remove the redundant setting of card->state in qeth_l?_set_online()'s error path. Signed-off-by: Julian Wiedmann <jwi@linux.ibm.com> Signed-off-by: David S.

2019-06-13s390/qeth: don't mask TX errors on IQD devicesJulian Wiedmann
Current code suppresses debug entries when an TX buffer completes in ERROR state with no error indication set in SBALF15.

If a FW assert is considered fatal, indicated by a new bit in the health buffer, reset the FW. After the reset go through the normal recovery flow. Only one PF needs to issue the reset, so an attempt is made to prevent the 2nd function from also issuing the reset. It's not an error if that happens, it just slows recovery.

2019-06-13net/mlx5: Control CR-space access by different PFsFeras Daoud
Since the FW can be shared between different PFs/VFs it is common that more than one health poll will detected a failure, this can lead to multiple resets which are unneeded. The solution is to use a FW locking mechanism using semaphore space to provide a way to allow only one device to collect the cr-dump and to issue a sw-reset.

2019-06-13net/mlx5: Handle SW reset of FW in error flowFeras Daoud
New mlx5 adapters allow the driver to reset the FW in the event of an error, this action called "SW Reset". When an SW reset is issued on any PF all PFs enter reset state which is a recoverable condition. The existing recovery flow was designed to allow the recovery of a VF after a PF driver reload. This patch adds the sw reset to the NIC states as a preparation for sw reset handling. When a software reset is issued the following occurs: 1. The NIC interface mode is set to 7 while the reset is in progress. 2. Once the reset completes the NIC interface mode is set to 1.

2019-06-13net/mlx5: Add Crdump supportAlex Vesker
Crdump allows the driver to retrieve a dump of the FW PCI crspace. This is useful in case of catastrophic issues which may require FW reset. The crspace dump can be used for later debug.

2019-06-13net/mlx5: Add Vendor Specific Capability access gatewayAlex Vesker
The Vendor Specific Capability (VSC) is used to activate a gateway interfacing with the device. The gateway is used to read or write device configurations, which are organized in different domains (spaces). A configuration access may result in multiple actions, reads, writes. Example usages are accessing the Crspace domain to read the crspace or locking a device semaphore using the Semaphore domain. The configuration access use pci_cfg_access to prevent parallel access to the VSC space by the driver and userspace calls.

2019-06-12net: ena: allow queue allocation backoff when low on memorySameeh Jubran
If there is not enough memory to allocate io queues the driver will try to allocate smaller queues. The backoff algorithm is as follows: 1. Try to allocate TX and RX and if successful. 1.1. return success 2. Divide by 2 the size of the larger of RX and TX queues (or both if their size is the same). 3. If TX or RX is smaller than 256 3.1. return failure. 4. else 4.1. go back to 1. Also change the tx_queue_size, rx_queue_size field names in struct adapter to requested_tx_queue_size and requested_rx_queue_size, and use RX and TX queue 0 for actual queue sizes. Explanation: The original fields were useless as they were simply used to assign values once from them to each of the queues in the adapter in ena_probe(). They could simply be deleted. However now that we have a backoff feature, we have use for them. In case of backoff there is a difference between the requested queue sizes and the actual sizes. Therefore there is a need to save the requested queue size for future retries of queue allocation (for example if allocation failed and then ifdown + ifup was called we want to start the allocation from the original requested size of the queues).
