Johannes Berg [Mon, 2 Aug 2021 14:28:27 +0000 (17:28 +0300)]
iwlwifi: mvm: avoid static queue number aliasing

When TVQM is enabled (iwl_mvm_has_new_tx_api() is true), then
queue numbers are just sequentially assigned 0, 1, 2, ...
Prior to TVQM, in DQA, there were some statically allocated
queue numbers:
 * IWL_MVM_DQA_AUX_QUEUE == 1,
 * both IWL_MVM_DQA_INJECT_MONITOR_QUEUE and
   IWL_MVM_DQA_P2P_DEVICE_QUEUE == 2, and
 * IWL_MVM_DQA_AP_PROBE_RESP_QUEUE == 9.

Now, these values are assigned to the members mvm->aux_queue,
mvm->snif_queue, mvm->probe_queue and mvm->p2p_dev_queue by
default. Normally, this doesn't really matter, and if TVQM is
in fact available we override them to the real values after
allocating a queue for use there.

However, this allocation doesn't always happen. For example,
for mvm->p2p_dev_queue (== 2) it only happens when the P2P
Device interface is started, if any. If it's not started, the
value in mvm->p2p_dev_queue remains 2. This wouldn't really
matter all that much if it weren't for iwl_mvm_is_static_queue()
which checks a queue number against one of those four static
numbers.

Now, if no P2P Device or monitor interface is added then queue
2 may be dynamically allocated, yet alias mvm->p2p_dev_queue or
mvm->snif_queue, and thus iwl_mvm_is_static_queue() erroneously
returns true for it. If it then gets full, all interface queues
are stopped, instead of just backpressuring against the one TXQ
that's really the only affected one.

This clearly can lead to issues, as everything is stopped even
if just a single TXQ filled its corresponding HW queue, if it
happens to have an appropriate number (2 or 9, AUX is always
reassigned.) Due to a mac80211 bug, this also led to a situation
in which the queues remained stopped across a deauthentication
and then attempts to connect to a new AP started failing, but
that's fixed separately.

Fix all of this by simply initializing the queue numbers to
the invalid value until they're used, if TVQM is enabled, and
also setting them back to that value when the queues are later
freed again.

This doesn't have a large effect - for frames that reach

the only affect here is for those after a firmware restart.

====================
samples: pktgen: enhance the ability to print the execution results of samples

This patch series improves the ability to print the execution result of pktgen
samples by adding a line which calls the function before termination and adding
trap SIGINT. Also, this series documents the latest pktgen usage options.

Currently, pktgen samples print the execution result when terminated usually.
However, sample03 is not working properly.

This is results of sample04 and sample03:

    # DEV=eth0 DEST_IP=10.1.0.1 DST_MAC=00:11:22:33:44:55 ./pktgen_sample04_many_flows.sh -n 1

    Running... ctrl^C to stop

Because sample03 doesn't call the function which prints the execution result
when terminated normally, unlike other samples. So the first commit solves
this issue by adding a line which calls the function before termination.

Also, all pktgen samples are able to send infinite messages per thread by
setting the count option to 0, and pktgen is stopped by Ctrl-C. However,
the sample besides sample{3...5} don't work appropriately because Ctrl-C stops
the script, not just pktgen.

This is results of samples:

    # DEV=eth0 DEST_IP=10.1.0.1 DST_MAC=00:11:22:33:44:55 ./pktgen_sample04_many_flows.sh -n 0

So the second commit solves this issue by adding trap SIGINT. Also, changes
control_c function to print_results to maintain consistency with other samples
on the first commit and second commit.

And current pktgen.rst documentation doesn't add the latest pktgen sample
usage options such as count and IPv6, and so on. Also, the old pktgen
sample scripts are still included in the document. The old scripts were removed
by the commit a4b6ade8359f ("samples/pktgen: remove remaining old pktgen

Thus, the last commit documents the latest pktgen sample usage and removes
old sample scripts. And fixes a minor typo.

rss_adder<7:0> = flow_tag<7:0> ^ flow_tag<15:8> ^
flow_tag<23:16> ^ flow_tag<31:24>

upfront using Toeplitz function and predict the queue selection

C0 HW revision onwards, The HW can configure the
rss_adder<7:0> as flow_tag<7:0> to align with standard NICs.

This patch adds an option to select legacy RSS adder mode

ravb: Add no_ptp_cfg_active to struct ravb_hw_info

There are some H/W differences for the gPTP feature between
R-Car Gen3, R-Car Gen2, and RZ/G2L as below.

1) On R-Car Gen2, gPTP support is not active in config mode.
2) On R-Car Gen3, gPTP support is active in config mode.
3) RZ/G2L does not support the gPTP feature.

Add a no_ptp_cfg_active hw feature bit to struct ravb_hw_info for
handling gPTP for R-Car Gen2.

ravb: Add multi_irq to struct ravb_hw_info

R-Car Gen3 supports separate interrupts for E-MAC and DMA queues,
whereas R-Car Gen2 and RZ/G2L have a single interrupt instead.

Add a multi_irq hw feature bit to struct ravb_hw_info to enable
this only for R-Car Gen3.

Vladimir Oltean says:

====================
Make sja1105 treat tag_8021q VLANs more like real DSA tags

This series solves a nuisance with the sja1105 driver, which is that
non-DSA tagged packets sent directly by the DSA master would still exit
the switch just fine.

We also had an issue for packets coming from the outside world with a
crafted DSA tag, the switch would not reject that tag but think it was
valid.
