2018-05-29Merge branch 'nfp-abm-RED-MQ-qdisc-offload'David S. Miller
Jakub Kicinski says: ==================== nfp: abm: RED/MQ qdisc offload This is second batch of advanced buffer management nfp driver changes. This series adds the qdisc offload. Support for a very simple subset of RED qdisc offload is added as needed for DCTCP ECN marking (min and max thresholds set to the same value). The first two patches fix glitches introduced by the previous series. We have to be careful about phys_port_name handling, because VFs share the same code path, and some user space may get confused by the names we chose. Since unlike previous offloads we can report the queue backlog both in bytes and packets we need to adjust how statistics are added up in the core (patch 6). There are some extra statistics we want to expose which don't fit into TC stats, namely counts of packets which have been fast- -forwarded without getting enqueued because there was no contention and number of packets that were ever queued (sum of all momentary backlogs). We expose those through ethtool stats (patches 8 and 9). Remaining 5 patches add MQ offload - to be able to set different configurations on different queues. Representors are made multi- -queue and we add offload support to MQ. MQ stats are added up before calling ->dump qdiscs on the children, and therefore don't include updated offload values. To avoid clearly incorrect stats MQ is made to also request stats update from offloads. This way we can correct the diff at the driver level. ==================== Signed-off-by: David S.

Call into the drivers, because of the additive nature of the stats drivers are aware of how much "pending updates" they have to children of the MQ.

Alternative approach would be to export qdisc_lookup() and make drivers check the root type themselves, but notification via ndo_setup_tc is more in line with other qdiscs.

In the general case, it means that packets are potentially sent to the mirror port before or after some actions were applied on them. To properly do that, we follow on the exact action order as set for the flow and make sure this will also be the case when we program the HW offload. If all the actions should apply before forwarding to the mirror and dest port, mirroring is just multicasting to the two vports. Otherwise, we split the TC flow to two HW rules, where the 1st applies only the actions needed up to the mirror (if there are such) and the 2nd the rest of the actions plus the forwarding to the dest vport. ================= 2) Move to order-0 only allocations (using fragmented work queues) for all work queues used by the driver, RX and TX descriptor rings (RQs, SQs and Completion Queues (CQs)), from Tariq Toukan. 3) Avoid resetting netdevice statistics on netdevice state changes, from Eran Ben Elisha. ==================== Signed-off-by: David S.

2018-05-29netfilter: nf_tables: use call_rcu in netlink dumpsFlorian Westphal
We can make all dumps and lookups lockless. Dumps currently only hold the nfnl mutex on the dump request itself. Dumps can span multiple syscalls, dump continuation doesn't acquire the nfnl mutex anywhere, i.e. the dump callbacks in nf_tables already use rcu and never rely on nfnl mutex being held. So, just switch all dumpers to rcu. This requires taking a module reference before dropping the rcu lock so rmmod is blocked, we also need to hold module reference over the entire dump operation sequence. netlink already supports this via the .module member in the netlink_dump_control struct. For the non-dump case (i.e. lookup of a specific tables, chains, etc), we need to swtich to _rcu list iteration primitive and make sure we use GFP_ATOMIC. This patch also adds the new nft_netlink_dump_start_rcu() helper that takes care of the get_ref, drop-rcu-lock,start dump, get-rcu-lock,put-ref sequence. The helper will be reused for all dumps. Rationale in all dump requests is: - use the nft_netlink_dump_start_rcu helper added in first patch - use GFP_ATOMIC and rcu list iteration - switch to .call_rcu ... thus making all dumps in nf_tables not depend on the nfnl mutex anymore. In the nf_tables_getgen: This callback just fetches the current base sequence, there is no need to serialize this with nfnl nft mutex.

2018-05-29netfilter: nf_tables: remove synchronize_rcu in commit phaseFlorian Westphal
synchronize_rcu() is expensive. The commit phase currently enforces an unconditional synchronize_rcu() after incrementing the generation counter. This is to make sure that a packet always sees a consistent chain, either nft_do_chain is still using old generation (it will skip the newly added rules), or the new one (it will skip old ones that might still be linked into the list). We could just remove the synchronize_rcu(), it would not cause a crash but it could cause us to evaluate a rule that was removed and new rule for the same packet, instead of either-or. To resolve this, add rule pointer array holding two generations, the current one and the future generation. In commit phase, allocate the rule blob and populate it with the rules that will be active in the new generation. Then, make this rule blob public, replacing the old generation pointer. Then the generation counter can be incremented. nft_do_chain() will either continue to use the current generation (in case loop was invoked right before increment), or the new one.

When there are 16 or more logical CPUs, we request for `IWL_MAX_RX_HW_QUEUES` (16) IRQs only as we limit to that number of IRQs, but later on we compare the number of IRQs returned to nr_online_cpus+2 instead of max_irqs, the latter being what we actually asked for.

2018-05-29rtlwifi: access skb->data to get C2H data by macroPing-Ke Shih
The format of C2H data is ID(1 byte) + Length(1 byte) + value, and it is more readable to use macros to access C2H data. Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2018-05-29rtlwifi: use sk_buff to queue C2H commandsPing-Ke Shih
We use 'struct rtl_c2hcmd' to store C2H commands originally, and the code is slightly complex to enqueue and dequeue and also wastes time to allocate and memcpy data. Since C2H commands are asynchronous events, they can be processed in work queue, so RX ISR enqueues C2H result in removal of rtl_c2h_packet_handler().

2018-05-29rtlwifi: remove hal_op c2h_content_parsingPing-Ke Shih
Similar to rx_command_packet, we can call rtl_c2h_content_parsing so the hal_op isn't necessary. Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2018-05-29rtlwifi: remove hal_op rx_command_packetPing-Ke Shih
Because the hal_op rx_command_packet does C2H handler if rx packet type is C2H, and the handler have been moved to base.c so we can call the handler directly. Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2018-05-29rtlwifi: remove duplicate C2H handlerPing-Ke Shih
Merge duplicate C2H handler and implement the handler in base.c. Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2018-05-29rtlwifi: Add hal_op c2h_ra_report_handler for special processPing-Ke Shih
We're going to merge C2H handler into one, but one special case is to handle RA_REPORT that implements in individual IC folder. So this commit adds a hal_op for caller in common code. Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2018-05-29rtlwifi: remove dummy hal_op rx_command_packet from rtl8188ee and rtl8723aePing-Ke Shih
The caller of hal_op rx_command_packet will assert function pointer before calling, so we can remove dummy functions safely. Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
