2019-12-30sfc: avoid duplicate error handling code in 'efx_ef10_sriov_set_vf_mac()'Christophe JAILLET1-3/+2
'eth_zero_addr()' is already called in the error handling path. This is harmless, but there is no point in calling it twice, so remove one. Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Signed-off-by: David S. Miller <davem@davemloft.net>

2019-12-20sfc: Include XDP packet headroom in buffer step size.Charles McLachlan1-7/+7
Correct a mismatch between rx_page_buf_step and the actual step size used when filling buffer pages. This patch fixes the page overrun that occured when the MTU was set to anything bigger than 1692.

2019-12-20sfc: fix channel allocation with brute forceEdward Cree2-22/+19
It was possible for channel allocation logic to get confused between what it had and what it wanted, and end up trying to use the same channel for both PTP and regular TX. This led to a kernel panic: BUG: unable to handle page fault for address: 0000000000047635 #PF: supervisor write access in kernel mode #PF: error_code(0x0002) - not-present page PGD 0 P4D 0 Oops: 0002 [#1] SMP PTI CPU: 0 PID: 0 Comm: swapper/0 Tainted: G W 5.4.0-rc3-ehc14+ #900 Hardware name: Dell Inc.

2019-12-12netdev: pass the stuck queue to the timeout handlerMichael S. Tsirkin2-2/+2
This allows incrementing the correct timeout statistic without any mess. Down the road, devices can learn to reset just the specific queue.

2019-11-22sfc: suppress MCDI errors from ARFSEdward Cree2-6/+30
In high connection count usage, the NIC's filter table may be filled with sufficiently many ARFS filters that further insertions fail. As this does not represent a correctness issue, do not log the resulting MCDI errors. Add a debug-level message under the (by default disabled) rx_status category instead; and take the opportunity to do a little extra expiry work. Since there are now multiple workitems able to call __efx_filter_rfs_expire on a given channel, it is possible for them to race and thus pass quotas which, combined, exceed rfs_filter_count. Thus, don't WARN_ON if we loop all the way around the table with quota left over.

2019-11-22sfc: change ARFS expiry mechanismEdward Cree4-32/+45
The old rfs_filters_added method for determining the quota could potentially allow the NIC to become filled with old filters, which never get tested for expiry. Instead, explicitly make expiry check work depend on the number of filters installed, and don't count checking slots without filters in as doing work. This guarantees that each filter will be checked for expiry at least once every thirty seconds (assuming the channel to which it belongs is NAPI polling actively) regardless of fill level.

The sfc driver can drop packets processed with XDP, notably when running out of buffer space on XDP_TX, or returning an unknown XDP action. This increments the rx_xdp_bad_drops ethtool counter. Call trace_xdp_exception everywhere rx_xdp_bad_drops is incremented, except for fragmented RX packets as the XDP program hasn't run yet. This allows it to easily be monitored from userspace.

We already scored points when handling the RX event, no-one else does this, and looking at the history it appears this was originally meant to only score on merges, not on GRO_NORMAL. Moreover, it gets in the way of changing GRO to not immediately pass GRO_NORMAL skbs to the stack.
