2019-12-26bnx2x: Fix accounting of vlan resources among the PFsManish Chopra
While testing max vlan configuration on the PF, firmware gets assert as driver was configuring number of vlans more than what is supported per port/engine, it was figured out that there is an implicit vlan (hidden default vlan consuming hardware cam entry resource) which is configured default for all the clients (PF/VFs) on client_init ramrod by the adapter implicitly, so when allocating resources among the PFs this implicit vlan should be considered or total vlan entries should be reduced by one to accommodate that default/implicit vlan entry.

2019-12-24s390/qeth: fix initialization on old HWJulian Wiedmann
I stumbled over an old OSA model that claims to support DIAG_ASSIST, but then rejects the cmd to query its DIAG capabilities. In the old code this was ok, as the returned raw error code was > 0. Now that we translate the raw codes to errnos, the "rc < 0" causes us to fail the initialization of the device. The fix is trivial: don't bail out when the DIAG query fails. Such an error is not critical, we can still use the device (with a slightly reduced set of features).

2019-12-24s390/qeth: Fix vnicc_is_in_use if rx_bcast not setAlexandra Winter
Symptom: After vnicc/rx_bcast has been manually set to 0, bridge_* sysfs parameters can still be set or written. Only occurs on HiperSockets, as OSA doesn't support changing rx_bcast. Vnic characteristics and bridgeport settings are mutually exclusive. rx_bcast defaults to 1, so manually setting it to 0 should disable bridge_* parameters. Instead it makes sense here to check the supported mask. If the card does not support vnicc at all, bridge commands are always allowed.

2019-12-24s390/qeth: fix false reporting of VNIC CHAR config failureAlexandra Winter
Symptom: Error message "Configuring the VNIC characteristics failed" in dmesg whenever an OSA interface on z15 is set online. The VNIC characteristics get re-programmed when setting a L2 device online. This follows the selected 'wanted' characteristics - with the exception that the INVISIBLE characteristic unconditionally gets switched off. For devices that don't support INVISIBLE (ie. OSA), the resulting IO failure raises a noisy error message ("Configuring the VNIC characteristics failed"). For IQD, INVISIBLE is off by default anyways. So don't unnecessarily special-case the INVISIBLE characteristic, and thereby suppress the misleading error message on OSA devices.

2019-12-24s390/qeth: fix qdio teardown after early init errorJulian Wiedmann
qeth_l?_set_online() goes through a number of initialization steps, and on any error uses qeth_l?_stop_card() to tear down the residual state. The first initialization step is qeth_core_hardsetup_card(). When this fails after having established a QDIO context on the device (ie. somewhere after qeth_mpc_initialize()), qeth_l?_stop_card() doesn't shut down this QDIO context again (since the card state hasn't progressed from DOWN at this stage). Even worse, we then call qdio_free() as final teardown step to free the QDIO data structures - while some of them are still hooked into wider QDIO infrastructure such as the IRQ list. This is inevitably followed by use-after-frees and other nastyness. Fix this by unconditionally calling qeth_qdio_clear_card() to shut down the QDIO context, and also to halt/clear any pending activity on the various IO channels. Remove the naive attempt at handling the teardown in qeth_mpc_initialize(), it clearly doesn't suffice and we're handling it properly now in the wider teardown code.

2019-12-24gtp: do not confirm neighbor when do pmtu updateHangbin Liu
When do IPv6 tunnel PMTU update and calls __ip6_rt_update_pmtu() in the end, we should not call dst_confirm_neigh() as there is no two-way communication. Although GTP only support ipv4 right now, and __ip_rt_update_pmtu() does not call dst_confirm_neigh(), we still set it to false to keep consistency with IPv6 code. v5: No change. v4: No change. v3: Do not remove dst_confirm_neigh, but add a new bool parameter in dst_ops.update_pmtu to control whether we should do neighbor confirm. Also split the big patch to small ones for each area. v2: Remove dst_confirm_neigh in __ip6_rt_update_pmtu.

2019-12-24net: add bool confirm_neigh parameter for dst_ops.update_pmtuHangbin Liu
The MTU update code is supposed to be invoked in response to real networking events that update the PMTU. In IPv6 PMTU update function __ip6_rt_update_pmtu() we called dst_confirm_neigh() to update neighbor confirmed time. But for tunnel code, it will call pmtu before xmit, like: - tnl_update_pmtu() - skb_dst_update_pmtu() - ip6_rt_update_pmtu() - __ip6_rt_update_pmtu() - dst_confirm_neigh() If the tunnel remote dst mac address changed and we still do the neigh confirm, we will not be able to update neigh cache and ping6 remote will failed. So for this ip_tunnel_xmit() case, _EVEN_ if the MTU is changed, we should not be invoking dst_confirm_neigh() as we have no evidence of successful two-way communication at this point. On the other hand it is also important to keep the neigh reachability fresh for TCP flows, so we cannot remove this dst_confirm_neigh() call. To fix the issue, we have to add a new bool parameter for dst_ops.update_pmtu to choose whether we should do neigh update or not. I will add the parameter in this patch and set all the callers to true to comply with the previous way, and fix the tunnel code one by one on later patches. v5: No change. v4: No change. v3: Do not remove dst_confirm_neigh, but add a new bool parameter in dst_ops.update_pmtu to control whether we should do neighbor confirm. Also split the big patch to small ones for each area. v2: Remove dst_confirm_neigh in __ip6_rt_update_pmtu.

2019-12-20net: ena: fix issues in setting interrupt moderation params in ethtoolArthur Kiyanovski
Issue 1: -------- Reproduction steps: 1. sudo ethtool -C eth0 rx-usecs 128 2. sudo ethtool -C eth0 adaptive-rx on 3. sudo ethtool -C eth0 adaptive-rx off 4. ethtool -c eth0 expected output: rx-usecs 128 actual output: rx-usecs 0 Reason for issue: In stage 3, ethtool userspace calls first the ena_get_coalesce() handler to get the current value of all properties, and then the ena_set_coalesce() handler. When ena_get_coalesce() is called the adaptive interrupt moderation is still on. There is an if in the code that returns the rx_coalesce_usecs only if the adaptive interrupt moderation is off. And since it is still on, rx_coalesce_usecs is not set, meaning it stays 0. Solution to issue: Remove this if static interrupt moderation intervals have nothing to do with dynamic ones. Issue 2: -------- Reproduction steps: 1. sudo ethtool -C eth0 adaptive-rx on 2. sudo ethtool -C eth0 rx-usecs 128 3. ethtool -c eth0 expected output: rx-usecs 128 actual output: rx-usecs 0 Reason for issue: In stage 2, when ena_set_coalesce() is called, the handler tests if rx adaptive interrupt moderation is on, and if it is, it returns before getting to the part in the function that sets the rx non-adaptive interrupt moderation interval. Solution to issue: Remove the return from the function when rx adaptive interrupt moderation is on. Also cleaned up the fixed code in ena_set_coalesce by grouping together adaptive interrupt moderation toggling, and using && instead of nested ifs.

2019-12-20net: ena: fix default tx interrupt moderation intervalArthur Kiyanovski
Current default non-adaptive tx interrupt moderation interval is 196 us. This value is too high and might cause the tx queue to fill up. In this commit we set the default non-adaptive tx interrupt moderation interval to 64 us in order to: 1. Reduce the probability of the queue filling-up (when compared to the current default value of 196 us). 2. Reduce unnecessary tx interrupt overhead (which happens if we set the default tx interval to 0). We determined experimentally that 64 us is an optimal value that reduces interrupt rate by more than 20% without affecting performance.

2019-12-20s390/qeth: fix promiscuous mode after resetJulian Wiedmann
When managing the promiscuous mode during an RX modeset, qeth caches the current HW state to avoid repeated programming of the same state on each modeset. But while tearing down a device, we forget to clear the cached state. So when the device is later set online again, the initial RX modeset doesn't program the promiscuous mode since we believe it is already enabled. Fix this by clearing the cached state in the tear-down path. Note that for the SBP variant of promiscuous mode, this accidentally works right now because we unconditionally restore the SBP role while re-initializing.

If for whatever reason the dasd_eckd_check_characteristics() function exits after at least some paths have their configuration data allocated those data is never freed again. In the error case the device->private pointer is set to NULL and dasd_eckd_uncheck_device() will exit without freeing the path data because of this NULL pointer. Fix by calling dasd_eckd_clear_conf_data() for error cases. Also use dasd_eckd_clear_conf_data() in dasd_eckd_uncheck_device() to avoid code duplication.

2019-12-20s390/dasd/cio: Interpret ccw_device_get_mdc return value correctlyJan Höppner
The max data count (mdc) is an unsigned 16-bit integer value as per AR documentation and is received via ccw_device_get_mdc() for a specific path mask from the CIO layer. The function itself also always returns a positive mdc value or 0 in case mdc isn't supported or couldn't be determined. Though, the comment for this function describes a negative return value to indicate failures. As a result, the DASD device driver interprets the return value of ccw_device_get_mdc() incorrectly. The error case is essentially a dead code path. To fix this behaviour, check explicitly for a return value of 0 and change the comment for ccw_device_get_mdc() accordingly. This fix merely enables the error code path in the DASD functions get_fcx_max_data() and verify_fcx_max_data(). The actual functionality stays the same and is still correct.
