2021-04-01net: enetc: add support for XDP_REDIRECTVladimir Oltean4-12/+218
The driver implementation of the XDP_REDIRECT action reuses parts from XDP_TX, most notably the enetc_xdp_tx function which transmits an array of TX software BDs. Only this time, the buffers don't have DMA mappings, we need to create them. When a BPF program reaches the XDP_REDIRECT verdict for a frame, we can employ the same buffer reuse strategy as for the normal processing path and for XDP_PASS: we can flip to the other page half and seed that to the RX ring. Note that scatter/gather support is there, but disabled due to lack of multi-buffer support in XDP (which is added by this series): https://patchwork.kernel.org/project/netdevbpf/cover/cover.1616179034.git.lorenzo@kernel.org/ Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S.

2021-04-01net: enetc: increase RX ring default sizeVladimir Oltean1-1/+1
As explained in the XDP_TX patch, when receiving a burst of frames with the XDP_TX verdict, there is a momentary dip in the number of available RX buffers. The system will eventually recover as TX completions will start kicking in and refilling our RX BD ring again. But until that happens, we need to survive with as few out-of-buffer discards as possible. This increases the memory footprint of the driver in order to avoid discards at 2.5Gbps line rate 64B packet sizes, the maximum speed available for testing on 1 port on NXP LS1028A.

2021-04-01net: enetc: add support for XDP_TXVladimir Oltean3-25/+228
For reflecting packets back into the interface they came from, we create an array of TX software BDs derived from the RX software BDs. Therefore, we need to extend the TX software BD structure to contain most of the stuff that's already present in the RX software BD structure, for reasons that will become evident in a moment. For a frame with the XDP_TX verdict, we don't reuse any buffer right away as we do for XDP_DROP (the same page half) or XDP_PASS (the other page half, same as the skb code path). Because the buffer transfers ownership from the RX ring to the TX ring, reusing any page half right away is very dangerous. So what we can do is we can recycle the same page half as soon as TX is complete. The code path is: enetc_poll -> enetc_clean_rx_ring_xdp -> enetc_xdp_tx -> enetc_refill_rx_ring (time passes, another MSI interrupt is raised) enetc_poll -> enetc_clean_tx_ring -> enetc_recycle_xdp_tx_buff But that creates a problem, because there is a potentially large time window between enetc_xdp_tx and enetc_recycle_xdp_tx_buff, period in which we'll have less and less RX buffers. Basically, when the ship starts sinking, the knee-jerk reaction is to let enetc_refill_rx_ring do what it does for the standard skb code path (refill every 16 consumed buffers), but that turns out to be very inefficient. The problem is that we have no rx_swbd->page at our disposal from the enetc_reuse_page path, so enetc_refill_rx_ring would have to call enetc_new_page for every buffer that we refill (if we choose to refill at this early stage). Very inefficient, it only makes the problem worse, because page allocation is an expensive process, and CPU time is exactly what we're lacking. Additionally, there is an even bigger problem: if we let enetc_refill_rx_ring top up the ring's buffers again from the RX path, remember that the buffers sent to transmission haven't disappeared anywhere. They will be eventually sent, and processed in enetc_clean_tx_ring, and an attempt will be made to recycle them. But surprise, the RX ring is already full of new buffers, because we were premature in deciding that we should refill. So not only we took the expensive decision of allocating new pages, but now we must throw away perfectly good and reusable buffers. So what we do is we implement an elastic refill mechanism, which keeps track of the number of in-flight XDP_TX buffer descriptors. We top up the RX ring only up to the total ring capacity minus the number of BDs that are in flight (because we know that those BDs will return to us eventually). The enetc driver manages 1 RX ring per CPU, and the default TX ring management is the same. So we do XDP_TX towards the TX ring of the same index, because it is affined to the same CPU. This will probably not produce great results when we have a tc-taprio/tc-mqprio qdisc on the interface, because in that case, the number of TX rings might be greater, but I didn't add any checks for that yet (mostly because I didn't know what checks to add). It should also be noted that we need to change the DMA mapping direction for RX buffers, since they may now be reflected into the TX ring of the same device. We choose to use DMA_BIDIRECTIONAL instead of unmapping and remapping as DMA_TO_DEVICE, because performance is better this way.

2021-04-01net: enetc: add support for XDP_DROP and XDP_PASSVladimir Oltean4-20/+281
For the RX ring, enetc uses an allocation scheme based on pages split into two buffers, which is already very efficient in terms of preventing reallocations / maximizing reuse, so I see no reason why I would change that. +--------+--------+--------+--------+--------+--------+--------+ | | | | | | | | | half B | half B | half B | half B | half B | half B | half B | | | | | | | | | +--------+--------+--------+--------+--------+--------+--------+ | | | | | | | | | half A | half A | half A | half A | half A | half A | half A | RX ring | | | | | | | | +--------+--------+--------+--------+--------+--------+--------+ ^ ^ | | next_to_clean next_to_alloc next_to_use +--------+--------+--------+--------+--------+ | | | | | | | half B | half B | half B | half B | half B | | | | | | | +--------+--------+--------+--------+--------+--------+--------+ | | | | | | | | | half B | half B | half A | half A | half A | half A | half A | RX ring | | | | | | | | +--------+--------+--------+--------+--------+--------+--------+ | | | ^ ^ | half A | half A | | | | | | next_to_clean next_to_use +--------+--------+ ^ | next_to_alloc then when enetc_refill_rx_ring is called, whose purpose is to advance next_to_use, it sees that it can take buffers up to next_to_alloc, and it says "oh, hey, rx_swbd->page isn't NULL, I don't need to allocate one!". The only problem is that for default PAGE_SIZE values of 4096, buffer sizes are 2048 bytes. While this is enough for normal skb allocations at an MTU of 1500 bytes, for XDP it isn't, because the XDP headroom is 256 bytes, and including skb_shared_info and alignment, we end up being able to make use of only 1472 bytes, which is insufficient for the default MTU. To solve that problem, we implement scatter/gather processing in the driver, because we would really like to keep the existing allocation scheme. A packet of 1500 bytes is received in a buffer of 1472 bytes and another one of 28 bytes. Because the headroom required by XDP is different (and much larger) than the one required by the network stack, whenever a BPF program is added or deleted on the port, we drain the existing RX buffers and seed new ones with the required headroom. We also keep the required headroom in rx_ring->buffer_offset. The simplest way to implement XDP_PASS, where an skb must be created, is to create an xdp_buff based on the next_to_clean RX BDs, but not clear those BDs from the RX ring yet, just keep the original index at which the BDs for this frame started. Then, if the verdict is XDP_PASS, instead of converting the xdb_buff to an skb, we replay a call to enetc_build_skb (just as in the normal enetc_clean_rx_ring case), starting from the original BD index. We would also like to be minimally invasive to the regular RX data path, and not check whether there is a BPF program attached to the ring on every packet. So we create a separate RX ring processing function for XDP. Because we only install/remove the BPF program while the interface is down, we forgo the rcu_read_lock() in enetc_clean_rx_ring, since there shouldn't be any circumstance in which we are processing packets and there is a potentially freed BPF program attached to the RX ring.

2021-04-01net: enetc: clean the TX software BD on the TX confirmation pathVladimir Oltean1-0/+4
With the future introduction of some new fields into enetc_tx_swbd such as is_xdp_tx, is_xdp_redirect etc, we need not only to set these bits to true from the XDP_TX/XDP_REDIRECT code path, but also to false from the old code paths. This is because TX software buffer descriptors are kept in a ring that is shadow of the hardware TX ring, so these structures keep getting reused, and there is always the possibility that when a software BD is reused (after we ran a full circle through the TX ring), the old user of the tx_swbd had set is_xdp_tx = true, and now we are sending a regular skb, which would need to set is_xdp_tx = false. To be minimally invasive to the old code paths, let's just scrub the software TX BD in the TX confirmation path (enetc_clean_tx_ring), once we know that nobody uses this software TX BD (tx_ring->next_to_clean hasn't yet been updated, and the TX paths check enetc_bd_unused which tells them if there's any more space in the TX ring for a new enqueue).

2021-04-01net: enetc: add a dedicated is_eof bit in the TX software BDVladimir Oltean2-4/+4
In the transmit path, if we have a scatter/gather frame, it is put into multiple software buffer descriptors, the last of which has the skb pointer populated (which is necessary for rearming the TX MSI vector and for collecting the two-step TX timestamp from the TX confirmation path). At the moment, this is sufficient, but with XDP_TX, we'll need to service TX software buffer descriptors that don't have an skb pointer, however they might be final nonetheless. So add a dedicated bit for final software BDs that we populate and check explicitly. Also, we keep looking just for an skb when doing TX timestamping, because we don't want/need that for XDP.

2021-04-01net: enetc: move skb creation into enetc_build_skbVladimir Oltean1-37/+44
We need to build an skb from two code paths now: from the plain RX data path and from the XDP data path when the verdict is XDP_PASS. Create a new enetc_build_skb function which contains the essential steps for building an skb based on the first and last positions of buffer descriptors within the RX ring. We also squash the enetc_process_skb function into enetc_build_skb, because what that function did wasn't very meaningful on its own. The "rx_frm_cnt++" instruction has been moved around napi_gro_receive for cosmetic reasons, to be in the same spot as rx_byte_cnt++, which itself must be before napi_gro_receive, because that's when we lose ownership of the skb.

This change is not needed for counters that increment only in NAPI context, as they are protected by the NAPI mechanism. Keep them as tls_* counters under 'struct mlx5e_rq_stats'.

2021-03-31net/mlx5e: kTLS, Fix TX counters atomicityTariq Toukan5-26/+33
Some TLS TX counters increment per socket/connection, and are not protected against parallel modifications from several cores. Switch them to atomic counters by taking them out of the SQ stats into the global atomic TLS stats. In this patch, we touch a single counter 'tx_tls_ctx' that counts the number of device-offloaded TX TLS connections added. Now that this counter can be increased without the for having the SQ context in hand, move it to the mlx5e_ktls_add_tx() callback where it really belongs, out of the fast data-path. This change is not needed for counters that increment only in NAPI context or under the TX lock, as they are already protected. Keep them as tls_* counters under 'struct mlx5e_sq_stats'.

2021-03-31net/mlx5e: Fix mapping of ct_label zeroAriel Levkovich1-7/+29
ct_label 0 is a default label each flow has and therefore there can be rules that match on ct_label=0 without a prior rule that set the ct_label to this value. The ct_label value is not used directly in the HW rules and instead it is mapped to some id within a defined range and this id is used to set and match the metadata register which carries the ct_label. If we have a rule that matches on ct_label=0, the hw rule will perform matching on a value that is != 0 because of the mapping from label to id. Since the metadata register default value is 0 and it was never set before to anything else by an action that sets the ct_label, there will always be a mismatch between that register and the value in the rule. To support such rule, a forced mapping of ct_label 0 to id=0 is done so that it will match the metadata register default value of 0.

On the N2100, instead of just marking the r8169 chips as having broken_parity_status, disable parity error reporting for them entirely. This was the only relevant place that set broken_parity_status, so we no longer need to check for it in the r8169 error interrupt handler.

2021-03-31mlxsw: spectrum_router: Only perform atomic nexthop bucket replacement when ↵Ido Schimmel1-2/+3
requested When cleared, the 'force' parameter in nexthop bucket replacement notifications indicates that a driver should try to perform an atomic replacement. Meaning, only update the contents of the bucket if it is inactive. Since mlxsw only queries buckets' activity once every second, there is no point in trying an atomic replacement if the idle timer interval is smaller than 1 second. Currently, mlxsw ignores the original value of 'force' and will always try an atomic replacement if the idle timer is not smaller than 1 second. Fix this by taking the original value of 'force' into account and never promoting a non-atomic replacement to an atomic one.
