| 2021-06-24 | nfp: Remove rcu_read_lock() around XDP program invocation |   Toke Høiland-Jørgensen | 1 | -2/+0 | |
| The nfp driver has rcu_read_lock()/rcu_read_unlock() pairs around XDP program invocations. However, the actual lifetime of the objects referred by the XDP program invocation is longer, all the way through to the call to xdp_do_flush(), making the scope of the rcu_read_lock() too small. While this is not actually an issue for the nfp driver because it doesn't support XDP_REDIRECT (and thus doesn't call xdp_do_flush()), the rcu_read_lock() is still unneeded. And With the addition of RCU annotations to the XDP_REDIRECT map types that take bh execution into account, lockdep even understands this to be safe, so there's really no reason to keep it around.

| 2020-12-09 | xdp: Remove the xdp_attachment_flags_ok() callback | Toke Høiland-Jørgensen | 1 | -6/+0 | |
| Since commit 7f0a838254bd ("bpf, xdp: Maintain info on attached XDP BPF programs in net_device"), the XDP program attachment info is now maintained in the core code. This interacts badly with the xdp_attachment_flags_ok() check that prevents unloading an XDP program with different load flags than it was loaded with. In practice, two kinds of failures are seen: - An XDP program loaded without specifying a mode (and which then ends up in driver mode) cannot be unloaded if the program mode is specified on unload. - The dev_xdp_uninstall() hook always calls the driver callback with the mode set to the type of the program but an empty flags argument, which means the flags_ok() check prevents the program from being removed, leading to bpf prog reference leaks. The original reason this check was added was to avoid ambiguity when multiple programs were loaded. With the way the checks are done in the core now, this is quite simple to enforce in the core code, so let's add a check there and get rid of the xdp_attachment_flags_ok() callback entirely.

| 2020-05-14 | nfp: Add XDP frame size to netronome driver |   Jesper Dangaard Brouer | 1 | -0/+6 | |
| The netronome nfp driver use PAGE_SIZE when xdp_prog is set, but xdp.data_hard_start begins at offset NFP_NET_RX_BUF_HEADROOM. Thus, adjust for this when setting xdp.frame_sz, as it counts from data_hard_start. When doing XDP_TX this driver is smart and instead of a full DMA-map does a DMA-sync on with packet length. As xdp_adjust_tail can now grow packet length, add checks to make sure that grow size is within the DMA-mapped size.

| 2019-12-19 | nfp: tls: implement the stream sync RX resync |   Jakub Kicinski | 1 | -2/+9 | |
| The simple RX resync strategy controlled by the kernel does not guarantee as good results as if the device helps by detecting the potential record boundaries and keeping track of them. We've called this strategy stream scan in the tls-offload doc. Implement this strategy for the NFP. The device sends a request for record boundary confirmation, which is then recorded in per-TLS socket state and responded to once record is reached. Because the device keeps track of records passing after the request was sent the response is not as latency sensitive as when kernel just tries to tell the device the information about the next record.

If this is not the case there is potential for abnormal behaviour and even the triggering of BUG() calls. Set the skb network header field before the mac header pull when doing a packet redirect.

| During probe we clear vNIC configuration in case the device wasn't closed cleanly by previous driver. Move that code before netdev init, so netdev init can already try to apply its config parameters.

| 2019-04-12 | nfp: add a mutex lock for the vNIC ctrl BAR | Jakub Kicinski | 1 | -12/+60 | |
| Soon we will try to write to the vNIC mailbox without RTNL held. Add a new mutex to protect access to specific parts of the PCI control BAR. Move the mailbox size checking to the mailbox lock() helper, where it can be more effective (happen prior to potential overwrite of other data).

| 2019-04-01 | net: move skb->xmit_more hint to softnet data |   Florian Westphal | 1 | -1/+1 | |
| There are two reasons for this. First, the xmit_more flag conceptually doesn't fit into the skb, as xmit_more is not a property related to the skb. Its only a hint to the driver that the stack is about to transmit another packet immediately. Second, it was only done this way to not have to pass another argument to ndo_start_xmit(). We can place xmit_more in the softnet data, next to the device recursion. The recursion counter is already written to on each transmit. The "more" indicator is placed right next to it. Drivers can use the netdev_xmit_more() helper instead of skb->xmit_more to check the "more packets coming" hint. skb->xmit_more is retained (but always 0) to not cause build breakage. This change takes care of the simple s/skb->xmit_more/netdev_xmit_more()/ conversions. Remaining drivers are converted in the next patches.

| If nn->port is defined it means that devlink_port has been registered for this port as well. Devlink core is handling the port name formatting.

| Follow-up patch is going to need a devlink port instance according to a netdev. Devlink port instance should be always available when devlink is used. So change the recently introduced ndo_get_devlink to ndo_get_devlink_port. With that, adjust the wrapper for the only user to get devlink pointer.
