The MSCC bug fix in 'net' had to be slightly adjusted because the register accesses are done slightly differently in net-next. Signed-off-by: David S. Miller

selftests: netdevsim: Always initialize 'RET' variable

2020-05-22T23:05:42Z

The variable is used by log_test() to check if the test case completely successfully or not. In case it is not initialized at the start of a test case, it is possible for the test case to fail despite not encountering any errors. Example: ``` ... TEST: Trap group statistics [ OK ] TEST: Trap policer [FAIL] Policer drop counter was not incremented TEST: Trap policer binding [FAIL] Policer drop counter was not incremented ``` Failure of trap_policer_test() caused trap_policer_bind_test() to fail as well. Fix by adding missing initialization of the variable.

devlink: refactor end checks in devlink_nl_cmd_region_read_dumpit

2020-05-15T00:36:25Z

Clean up after recent fixes, move address calculations around and change the variable init, so that we can have just one start_offset == end_offset check. Make the check a little stricter to preserve the -EINVAL error if requested start offset is larger than the region itself. Signed-off-by: Jakub Kicinski Signed-off-by: David S. Miller

devlink: let kernel allocate region snapshot id

2020-05-04T18:58:31Z

Currently users have to choose a free snapshot id before calling DEVLINK_CMD_REGION_NEW. This is potentially racy and inconvenient. Make the DEVLINK_ATTR_REGION_SNAPSHOT_ID optional and try to allocate id automatically. Send a message back to the caller with the snapshot info. Example use: $ devlink region new netdevsim/netdevsim1/dummy netdevsim/netdevsim1/dummy: snapshot 1 $ id=$(devlink -j region new netdevsim/netdevsim1/dummy | \ jq '.[][][][]') $ devlink region dump netdevsim/netdevsim1/dummy snapshot $id [...] $ devlink region del netdevsim/netdevsim1/dummy snapshot $id v4: - inline the notification code v3: - send the notification only once snapshot creation completed. v2: - don't wrap the line containing extack; - add a few sentences to the docs.

selftests: netdevsim: Add test cases for devlink-trap policers

2020-03-31T00:54:59Z

Add test cases for packet trap policer set / show commands as well as for the binding of these policers to packet trap groups. Both good and bad flows are tested for maximum coverage. v2: * Add test case with new 'fail_trap_policer_set' knob * Add test case for partially modified trap group Signed-off-by: Ido Schimmel Signed-off-by: David S.

netdevsim: Change dummy reporter auto recover default

2020-03-30T18:17:34Z

Health reporters should be registered with auto recover set to true. Align dummy reporter behaviour with that, as in later patch the option to set auto recover behaviour will be removed. In addition, align netdevsim selftest to the new default value. Signed-off-by: Eran Ben Elisha Reviewed-by: Jiri Pirko Signed-off-by: David S. Miller
