2019-09-06net: sched: fix reordering issuesEric Dumazet
Whenever MQ is not used on a multiqueue device, we experience serious reordering problems. Bisection found the cited commit. The issue can be described this way : - A single qdisc hierarchy is shared by all transmit queues. (eg : tc qdisc replace dev eth0 root fq_codel) - When/if try_bulk_dequeue_skb_slow() dequeues a packet targetting a different transmit queue than the one used to build a packet train, we stop building the current list and save the 'bad' skb (P1) in a special queue. (bad_txq) - When dequeue_skb() calls qdisc_dequeue_skb_bad_txq() and finds this skb (P1), it checks if the associated transmit queues is still in frozen state. If the queue is still blocked (by BQL or NIC tx ring full), we leave the skb in bad_txq and return NULL. - dequeue_skb() calls q->dequeue() to get another packet (P2) The other packet can target the problematic queue (that we found in frozen state for the bad_txq packet), but another cpu just ran TX completion and made room in the txq that is now ready to accept new packets. - Packet P2 is sent while P1 is still held in bad_txq, P1 might be sent at next round. In practice P2 is the lead of a big packet train (P2,P3,P4 ...) filling the BQL budget and delaying P1 by many packets :/ To solve this problem, we have to block the dequeue process as long as the first packet in bad_txq can not be sent. Reordering issues disappear and no side effects have been seen.

2019-09-06net: phy: Do not check Link status when loopback is enabledJose Abreu
While running stmmac selftests I found that in my 1G setup some tests were failling when running with PHY loopback enabled. It looks like when loopback is enabled the PHY will report that Link is down even though there is a valid connection. As in loopback mode the data will not be sent anywhere we can bypass the logic of checking if Link is valid thus saving unecessary reads.

2019-09-06forcedeth: use per cpu to collect xmit/recv statisticsZhu Yanjun
When testing with a background iperf pushing 1Gbit/sec traffic and running both ifconfig and netstat to collect statistics, some deadlocks occurred. Ifconfig and netstat will call nv_get_stats64 to get software xmit/recv statistics. In the commit f5d827aece36 ("forcedeth: implement ndo_get_stats64() API"), the normal tx/rx variables is to collect tx/rx statistics. The fix is to replace normal tx/rx variables with per cpu 64-bit variable to collect xmit/recv statistics. The per cpu variable will avoid deadlocks and provide fast efficient statistics updates. In nv_probe, the per cpu variable is initialized. In nv_remove, this per cpu variable is freed. In xmit/recv process, this per cpu variable will be updated. In nv_get_stats64, this per cpu variable on each cpu is added up. Then the driver can get xmit/recv packets statistics. A test runs for several days with this commit, the deadlocks disappear and the performance is better.

peakrate For high speed adapter like Mellanox CX-5 card, it can reach upto 100 Gbits per second bandwidth. Currently htb already supports 64bit rate in tc utility. However police action rate and peakrate are still limited to 32bit value (upto 32 Gbits per second). Add 2 new attributes TCA_POLICE_RATE64 and TCA_POLICE_RATE64 in kernel for 64bit support so that tc utility can use them for 64bit rate and peakrate value to break the 32bit limit, and still keep the backward binary compatibility.

2019-09-06ALSA: firewire-tascam: add note for FE-8Takashi Sakamoto
TASCAM FE-8 is the rest of model in TASCAM FireWire series. This device has no functionality to process audio signal and MIDI messages. Instead, it transfers control messages to host system corresponding to operations for some faders, buttons and knobs on its surface. Unlike the other devices in this series, the control messages are transmitted by asynchronous transactions. Some registers of device are used for registration of destination address for the transaction. The transaction includes quadlet-aligned data up to 32 quadlets. Userspace applications can receive the transaction and parse it for control message via Linux FireWire subsystem, without any support by ALSA firewire-tascam driver. Therefore the driver gives no support for it. This commit removes placeholder for FE-8 and add some comment for its functionalities as notes. $ python2 linux-firewire-utils/src/crpp < ~/git/am-config-rom/tascam/tascam-fe8.img ROM header and bus information block ----------------------------------------------------------------- 400 040f4798 bus_info_length 4, crc_length 15, crc 18328 (should be 14256) 404 31333934 bus_name "1394" 408 20ff7002 irmc 0, cmc 0, isc 1, bmc 0, cyc_clk_acc 255, max_rec 7 (256) 40c 00022eff company_id 00022e | 410 a094dcb7 device_id ffa094dcb7 | EUI-64 00022effa094dcb7 root directory ----------------------------------------------------------------- 414 0004bccc directory_length 4, crc 48332 418 0300022e vendor 41c 0c0083c0 node capabilities per IEEE 1394 420 8d000006 --> eui-64 leaf at 438 424 d1000001 --> unit directory at 428 unit directory at 428 ----------------------------------------------------------------- 428 0003eda4 directory_length 3, crc 60836 42c 1200022e specifier id 430 13800001 version 434 d4000004 --> dependent info directory at 444 eui-64 leaf at 438 ----------------------------------------------------------------- 438 0002461e leaf_length 2, crc 17950 43c 00022eff company_id 00022e | 440 a094dcb7 device_id ffa094dcb7 | EUI-64 00022effa094dcb7 dependent info directory at 444 ----------------------------------------------------------------- 444 0002ae47 directory_length 2, crc 44615 448 81000002 --> descriptor leaf at 450 44c 82000006 --> bus dependent info leaf at 464 descriptor leaf at 450 ----------------------------------------------------------------- 450 0004a79e leaf_length 4, crc 42910 454 00000000 textual descriptor 458 00000000 minimal ASCII 45c 54415343 "TASC" 460 414d0000 "AM" bus dependent info leaf at 464 ----------------------------------------------------------------- 464 0004a7d8 leaf_length 4, crc 42968 468 00000000 46c 00000000 470 46452d38 474 00000000 Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Link: https://lore.kernel.org/r/20190906125544.13800-1-o-takashi@sakamocchi.jp Signed-off-by: Takashi Iwai <tiwai@suse.de>
2019-09-06net: openvswitch: Set OvS recirc_id from tc chain indexPaul Blakey
Offloaded OvS datapath rules are translated one to one to tc rules, for example the following simplified OvS rule: recirc_id(0),in_port(dev1),eth_type(0x0800),ct_state(-trk) actions:ct(),recirc(2) Will be translated to the following tc rule: $ tc filter add dev dev1 ingress \ prio 1 chain 0 proto ip \ flower tcp ct_state -trk \ action ct pipe \ action goto chain 2 Received packets will first travel though tc, and if they aren't stolen by it, like in the above rule, they will continue to OvS datapath. Since we already did some actions (action ct in this case) which might modify the packets, and updated action stats, we would like to continue the proccessing with the correct recirc_id in OvS (here recirc_id(2)) where we left off. To support this, introduce a new skb extension for tc, which will be used for translating tc chain to ovs recirc_id to handle these miss cases. Last tc chain index will be set by tc goto chain action and read by OvS datapath.

2019-09-06iwlwifi: mvm: handle BAR_FRAME_RELEASE (0xc2) notificationJohannes Berg
In prior hardware generations (e.g. 9000 series), we received the BAR frame with fake NSSN information to handle releasing frames from the reorder buffer for the default queue, the other queues were getting the FRAME_RELEASE notification in this case. With multi-TID block-ack, the firmware no longer sends us the BAR frame because the fake RX is quite big (just the metadata is around 48 bytes or so). Instead, it now sends us one (or multiple) special release notifications (0xc2). The hardware consumes these as well, but only generates the FRAME_RELEASE (0xc3) for queues other than the default queue. We thus need to handle them in the same way we handle the normal FRAME_RELEASE. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2019-09-06iwlwifi: mvm: drop BA sessions on too many old-SN framesJohannes Berg
Certain APs (I think a certain Broadcom model) interact badly with our full state BA bitmap handling, and if triggered badly with many powersave transitions they keep sending frames from before the window, which our hardware then doesn't appear to ACK (to them) since it has moved on and is sending ACKs for higher SNs now. Try to detect this situation and if this keeps happening, disable the aggregation session. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

2019-09-06iwlwifi: add support for suspend-resume flow for new device generationHaim Dreyfuss
The new device generation has a slightly different suspend resume flow Currently, the way the driver instruct the device to move to D3 is by sending D3_CONFIG_CMD. Instead of using the host command the indication is by writing to the doorbell interrupt. The FW will respond with interrupt to indicate transition completion.

2019-09-06iwlwifi: always access the trans configuration via transLuca Coelho
Stop accessing the trans configuration via the iwl_cfg structure and always access it via the iwl_trans structure. This completes the requirements to disassociate the trans-specific configuration from the rest of the configuration. Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2019-09-06iwlwifi: pass the iwl_trans instead of cfg to some functionsShaul Triebitz

2019-09-06iwlwifi: add a pointer to the trans_cfg directly in transLuca Coelho
Add a pointer to the iwl_trans structure and point it to the trans part of the cfg. This is the first step in disassociating the trans configuration from the rest of the configuration. Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2019-09-06iwlwifi: pass the iwl_config_trans_params when neededLuca Coelho
Instead of accessing the iwl_config_trans_params from the cfg that is stored in the trans struct, pass this structure directly to functions that need it during trans_alloc. This will be useful to isolate the elements needed during allocation and pass them separately before the actual cfg struct is known. Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2019-09-06iwlwifi: pcie: set iwl_trans->cfg later in the probe functionLuca Coelho
Instead of setting the cfg to iwl_trans already during allocation, set it only later when we have had the time to decide which cfg to use. This is part of the effort to be able to decide the cfg based on HW revision and RF ID after iwl_trans_alloc() has been called. For now, since we still have a bunch of code checking the HW revision and the RF ID, we set iwl_trans->cfg early, even before we decided the real cfg to use. We only use the trans configuration at this point, so this is fine for now. In the future, the trans configuration will be completely independent from the rest of the config structure, so we'll be able to avoid this. Additionally, we can't access the PRPH registers in iwl_trans_alloc() anymore, so move the HW REV C-step check for family 8000 code later to the probe function as well. This step is probably not necessary, but if that's the case it should be removed separately later on. Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2019-09-06iwlwifi: pcie: move some cfg mangling from trans_pcie_alloc to probeLuca Coelho

2019-09-06iwlwifi: pcie: use the cfg we passed to iwl_trans_pcie_alloc()Luca Coelho
Instead of using iwl_trans->cfg in iwl_trans_pcie_alloc(), use the local argument that we received. This will allow us to not to set the cfg during iwl_trans_alloc() so it can be decided later. Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2019-09-06iwlwifi: separate elements from cfg that are needed by trans_allocLuca Coelho
In order to be able to select the cfg depending on the HW revision or on the RF ID, we need to set up the trans before selecting the cfg. To do so, move the elements from cfg that are needed by iwl_trans_alloc() to a separate struct at the top of the cfg, so it can be used by other cfg types as well, before selecting the rest of the configuration.
