Add rx reporter, which supports diagnose call-back. Diagnostics output include: information common to all RQs: RQ type, RQ size, RQ stride size, CQ size and CQ stride size. In addition advertise information per RQ and its related icosq and attached CQ. $ devlink health diagnose pci/0000:00:0b.0 reporter rx Common config: RQ: type: 2 stride size: 2048 size: 8 CQ: stride size: 64 size: 1024 RQs: channel ix: 0 rqn: 4308 HW state: 1 SW state: 3 posted WQEs: 7 cc: 7 ICOSQ HW state: 1 CQ: cqn: 1032 HW status: 0 channel ix: 1 rqn: 4313 HW state: 1 SW state: 3 posted WQEs: 7 cc: 7 ICOSQ HW state: 1 CQ: cqn: 1036 HW status: 0 channel ix: 2 rqn: 4318 HW state: 1 SW state: 3 posted WQEs: 7 cc: 7 ICOSQ HW state: 1 CQ: cqn: 1040 HW status: 0 channel ix: 3 rqn: 4323 HW state: 1 SW state: 3 posted WQEs: 7 cc: 7 ICOSQ HW state: 1 CQ: cqn: 1044 HW status: 0 $ devlink health diagnose pci/0000:00:0b.0 reporter rx -jp { "Common config": { "RQ": { "type": 2, "stride size": 2048, "size": 8 }, "CQ": { "stride size": 64, "size": 1024 } }, "RQs": [ { "channel ix": 0, "rqn": 4308, "HW state": 1, "SW state": 3, "posted WQEs": 7, "cc": 7, "ICOSQ HW state": 1, "CQ": { "cqn": 1032, "HW status": 0 } },{ "channel ix": 1, "rqn": 4313, "HW state": 1, "SW state": 3, "posted WQEs": 7, "cc": 7, "ICOSQ HW state": 1, "CQ": { "cqn": 1036, "HW status": 0 } },{ "channel ix": 2, "rqn": 4318, "HW state": 1, "SW state": 3, "posted WQEs": 7, "cc": 7, "ICOSQ HW state": 1, "CQ": { "cqn": 1040, "HW status": 0 } },{ "channel ix": 3, "rqn": 4323, "HW state": 1, "SW state": 3, "posted WQEs": 7, "cc": 7, "ICOSQ HW state": 1, "CQ": { "cqn": 1044, "HW status": 0 } } ] } Signed-off-by:Aya Levin <ayal@mellanox.com> Reviewed-by:

Move the tx bottom function from NAPI to a new tasklet. Then, for multi-cores, the bottom functions of tx and rx may be run at same time with different cores. This is used to improve performance. On x86, Tx/Rx 943/943 Mbits/sec -> 945/944. For arm platform, Tx/Rx: 917/917 Mbits/sec -> 933/933. Signed-off-by:

Xin Long says: ==================== sctp: support per endpoint auth and asconf flags This patchset mostly does 3 things: 1. add per endpint asconf flag and use asconf flag properly and add SCTP_ASCONF_SUPPORTED sockopt. 2. use auth flag properly and add SCTP_AUTH_SUPPORTED sockopt. 3. remove the 'global feature switch' to discard chunks. ==================== Signed-off-by: -
Xin Long authored
The netns sctp feature flags shouldn't work as a global switch, which is mostly like a firewall/netfilter's job. Also, it will break asoc as it discard or accept chunks incorrectly when net sctp.x_enable is changed after the asoc is created. Since each type of chunk's processing function will check the corresp asoc's feature flag, this 'global switch' should be removed, and net sctp.x_enable will only work as the default feature flags for the future sctp sockets/endpoints.

SCTP_AUTH_SUPPORTED sockopt is used to set enpoint's auth flag. With this feature, each endpoint will have its own flag for its future asoc's auth_capable, instead of netns auth flag. Note that when both ep's auth_enable is enabled, endpoint auth related data should be initialized. If asconf_enable is also set, SCTP_CID_ASCONF/SCTP_CID_ASCONF_ACK should be added into auth_chunk_list. Signed-off-by:

This patch is to make addip/asconf flag per endpoint, and its value is initialized by the per netns flag, net->sctp.addip_enable. It also replaces the checks of net->sctp.addip_enable with ep->asconf_enable in some places. Signed-off-by:

Concurrent tests use several commands to update rules in parallel: 'find' prints names of batch files in tmp directory and pipes result to 'xargs' which runs instance of tc per batch file in parallel.

A lot of tests reuse $DEV1 veth name for naming dummy device. This causes problem when tdc is invoked without specifying a test group and tries to execute all tests. In this case tdc instantiates ns plugin, which creates veth pair once before running tests. However, if any of the tests that reuse $DEV1 run before test that depend on ns plugin, it will delete $DEV1 as a part of teardown section: =====> Test 3b88: Delete ingress qdisc twice [3770/41080] -----> prepare stage ns/SubPlugin.adjust_command adjust_command: stage is setup; inserting netns stuff in command [/sbin/ip link add dev v0p1 type dummy || /bin/true] list [['/sbin/ip', 'link', 'add', 'dev', 'v0p1', 'type', 'dummy', '||', '/bin/true']] adjust_command: return command [ip netns exec tcut /sbin/ip link add dev v0p1 type dummy || /bin/true] command "ip netns exec tcut /sbin/ip link add dev v0p1 type dummy || /bin/true" ns/SubPlugin.adjust_command adjust_command: stage is setup; inserting netns stuff in command [/sbin/tc qdisc add dev v0p1 ingress] list [['/sbin/tc', 'qdisc', 'add', 'dev', 'v0p1', 'ingress']] adjust_command: return command [ip netns exec tcut /sbin/tc qdisc add dev v0p1 ingress] command "ip netns exec tcut /sbin/tc qdisc add dev v0p1 ingress" ns/SubPlugin.adjust_command adjust_command: stage is setup; inserting netns stuff in command [/sbin/tc qdisc del dev v0p1 ingress] list [['/sbin/tc', 'qdisc', 'del', 'dev', 'v0p1', 'ingress']] adjust_command: return command [ip netns exec tcut /sbin/tc qdisc del dev v0p1 ingress] command "ip netns exec tcut /sbin/tc qdisc del dev v0p1 ingress" -----> execute stage ns/SubPlugin.adjust_command adjust_command: stage is execute; inserting netns stuff in command [/sbin/tc qdisc del dev v0p1 ingress] list [['/sbin/tc', 'qdisc', 'del', 'dev', 'v0p1', 'ingress']] adjust_command: return command [ip netns exec tcut /sbin/tc qdisc del dev v0p1 ingress] command "ip netns exec tcut /sbin/tc qdisc del dev v0p1 ingress" -----> verify stage ns/SubPlugin.adjust_command adjust_command: stage is verify; inserting netns stuff in command [/sbin/tc qdisc show dev v0p1] list [['/sbin/tc', 'qdisc', 'show', 'dev', 'v0p1']] adjust_command: return command [ip netns exec tcut /sbin/tc qdisc show dev v0p1] command "ip netns exec tcut /sbin/tc qdisc show dev v0p1" -----> teardown stage ns/SubPlugin.adjust_command adjust_command: stage is teardown; inserting netns stuff in command [/sbin/ip link del dev v0p1 type dummy] list [['/sbin/ip', 'link', 'del', 'dev', 'v0p1', 'type', 'dummy']] adjust_command: return command [ip netns exec tcut /sbin/ip link del dev v0p1 type dummy] command "ip netns exec tcut /sbin/ip link del dev v0p1 type dummy" After this ns-dependent tests will fail because dev doesn't exist: =====> Test 901f: Add fw filter with prio at 32-bit maxixum -----> prepare stage ns/SubPlugin.adjust_command adjust_command: stage is setup; inserting netns stuff in command [/sbin/tc qdisc add dev v0p1 ingress] list [['/sbin/tc', 'qdisc', 'add', 'dev', 'v0p1', 'ingress']] adjust_command: return command [ip netns exec tcut /sbin/tc qdisc add dev v0p1 ingress] command "ip netns exec tcut /sbin/tc qdisc add dev v0p1 ingress" -----> prepare stage *** Could not execute: "$TC qdisc add dev $DEV1 ingress" -----> prepare stage *** Error message: "Cannot find device "v0p1" " returncode 1; expected [0] -----> prepare stage *** Aborting test run. <_io.BufferedReader name=3> *** stdout *** <_io.BufferedReader name=5> *** stderr *** "-----> prepare stage" did not complete successfully Exception <class '__main__.PluginMgrTestFail'> ('setup', None, '"-----> prepare stage" did not complete successfully') (caught in test_runner, running test 477 901f Add fw filter with prio at 32-bit maxixum stage setup) --------------- traceback File "./tdc.py", line 371, in test_runner res = run_one_test(pm, args, index, tidx) File "./tdc.py", line 272, in run_one_test prepare_env(args, pm, 'setup', "-----> prepare stage", tidx["setup"]) File "./tdc.py", line 247, in prepare_env '"{}" did not complete successfully'.format(prefix)) --------------- Fix the issue by introducing standalone $DUMMY config variable and substitute all usage of $DEV1 in tests that don't depend on ns plugin.

The maximum key description size is 4095. Commit f771fde8 ("keys: Simplify key description management") inadvertantly reduced that to 255 and made sizes between 256 and 4095 work weirdly, and any size whereby size & 255 == 0 would cause an assertion in __key_link_begin() at the following line: BUG_ON(index_key->desc_len == 0); This can be fixed by simply increasing the size of desc_len in struct keyring_index_key to a u16. Note the argument length test in keyutils only checked empty descriptions and descriptions with a size around the limit (ie. 4095) and not for all the values in between, so it missed this. This has been addressed and https://git.kernel.org/pub/scm/linux/kernel/git/dhowells/keyutils.git/commit/?id=066bf56807c26cd3045a25f355b34c1d8a20a5aa now exhaustively tests all possible lengths of type, description and payload and then some.

When a Tx timestamp is requested, a pointer to the skb is stored in the ravb_tstamp_skb struct. This was done without an skb_get. There exists the possibility that the skb could be freed by ravb_tx_free (when ravb_tx_free is called from ravb_start_xmit) before the timestamp was processed, leading to a use-after-free bug. Use skb_get when filling a ravb_tstamp_skb struct, and add appropriate frees/consumes when a ravb_tstamp_skb struct is freed. Fixes: c156633f ("Renesas Ethernet AVB driver proper") Signed-off-by:

Currently all QDMA registers are named "MTK_QDMA_foo" in this driver with one exception: MTK_QMTK_INT_STATUS. This patch renames MTK_QMTK_INT_STATUS to MTK_QDMA_INT_STATUS so that all macros follow this rule. Signed-off-by:

Pablo Neira Ayuso says: ==================== flow_offload hardware priority fixes This patchset contains two updates for the flow_offload users: 1) Pass the major tc priority to drivers so they do not have to lshift it. This is a preparation patch for the fix coming in patch #2. 2) Set the hardware priority from the netfilter basechain priority, some drivers break when using the existing hardware priority number that is set to zero. v5: fix patch 2/2 to address a clang warning and to simplify the priority mapping. ==================== Signed-off-by:
