2021-05-23net/sched: fq_pie: re-factor fix for fq_pie endless loopDavide Caratti1-4/+4
the patch that fixed an endless loop in_fq_pie_init() was not considering that 65535 is a valid class id. The correct bugfix for this infinite loop is to change 'idx' to become an u32, like Colin proposed in the past [1]. Fix this as follows: - restore 65536 as maximum possible values of 'flows_cnt' - use u32 'idx' when iterating on 'q->flows' - fix the TDC selftest This reverts commit bb2f930d6dd708469a587dc9ed1efe1ef969c0bf.

2019-08-19tc-testing: use dedicated DUMMY interface name for dummy devVlad Buslov3-164/+164
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.
