2024-03-05selftests/tc-testing: require an up to date iproute2 for blockcast testsPedro Tammela1-0/+7
Add the dependsOn test check for all the mirred blockcast tests. It will prevent the issue reported by LKFT which happens when an older iproute2 is used to run the current tdc. Tests are skipped if the dependsOn check fails.

2019-06-25tc-testing: Restore original behaviour for namespaces in tdcLucas Bates1-0/+6
This patch restores the original behaviour for tdc prior to the introduction of the plugin system, where the network namespace functionality was split from the main script. It introduces the concept of required plugins for testcases, and will automatically load any plugin that isn't already enabled when said plugin is required by even one testcase. Additionally, the -n option for the nsPlugin is deprecated so the default action is to make use of the namespaces. Instead, we introduce -N to not use them, but still create the veth pair. buildebpfPlugin's -B option is also deprecated. If a test cases requires the features of a specific plugin in order to pass, it should instead include a new key/value pair describing plugin interactions: "plugins": { "requires": "buildebpfPlugin" }, A test case can have more than one required plugin: a list can be inserted as the value for 'requires'.

Include following tests: 377e - Add pedit action with RAW_OP offset u32 a0ca - Add pedit action with RAW_OP offset u32 (INVALID) dd8a - Add pedit action with RAW_OP offset u16 u16 53db - Add pedit action with RAW_OP offset u16 (INVALID) 5c7e - Add pedit action with RAW_OP offset u8 add value 2893 - Add pedit action with RAW_OP offset u8 quad 3a07 - Add pedit action with RAW_OP offset u8-u16-u8 ab0f - Add pedit action with RAW_OP offset u16-u8-u8 9d12 - Add pedit action with RAW_OP offset u32 set u16 clear u8 invert ebfa - Add pedit action with RAW_OP offset overflow u32 (INVALID) f512 - Add pedit action with RAW_OP offset u16 at offmask shift set c2cb - Add pedit action with RAW_OP offset u32 retain value 86d4 - Add pedit action with LAYERED_OP eth set src & dst c715 - Add pedit action with LAYERED_OP eth set src (INVALID) ba22 - Add pedit action with LAYERED_OP eth type set/clear sequence 5810 - Add pedit action with LAYERED_OP ip set src & dst 1092 - Add pedit action with LAYERED_OP ip set ihl & dsfield 02d8 - Add pedit action with LAYERED_OP ip set ttl & protocol 3e2d - Add pedit action with LAYERED_OP ip set ttl (INVALID) 31ae - Add pedit action with LAYERED_OP ip ttl clear/set 486f - Add pedit action with LAYERED_OP ip set duplicate fields e790 - Add pedit action with LAYERED_OP ip set ce, df, mf, firstfrag, nofrag fields 6829 - Add pedit action with LAYERED_OP beyond ip set dport & sport afd8 - Add pedit action with LAYERED_OP beyond ip set icmp_type & icmp_code 3143 - Add pedit action with LAYERED_OP beyond ip set dport (INVALID) fc1f - Add pedit action with LAYERED_OP ip6 set src & dst 6d34 - Add pedit action with LAYERED_OP ip6 dst retain value (INVALID) 6f5e - Add pedit action with LAYERED_OP ip6 flow_lbl 6795 - Add pedit action with LAYERED_OP ip6 set payload_len, nexthdr, hoplimit 1442 - Add pedit action with LAYERED_OP tcp set dport & sport b7ac - Add pedit action with LAYERED_OP tcp sport set (INVALID) cfcc - Add pedit action with LAYERED_OP tcp flags set 3bc4 - Add pedit action with LAYERED_OP tcp set dport, sport & flags fields f1c8 - Add pedit action with LAYERED_OP udp set dport & sport d784 - Add pedit action with mixed RAW/LAYERED_OP #1 70ca - Add pedit action with mixed RAW/LAYERED_OP #2 Signed-off-by: Dmytro Linkin <dmitrolin@mellanox.com> Signed-off-by: David S.
