2023-03-18vppinfra: fix corner-cases in bihash lookupDave Barach1-1/+1
In a case where one pounds on a single kvp in a KVP_AT_BUCKET_LEVEL table, the code would sporadically return a transitional value (junk) from a half-deleted kvp. At most, 64-bits worth of the kvp will be written atomically, so using memset(...) to smear 0xFF's across a kvp to free it left a lot to be desired. Performance impact: very mild positive, thanks to FC for doing a multi-thread host stack perf/scale test. Added an ASSERT to catch attempts to add a (key,value) pair which contains the magic "free kvp" value.

2022-10-13l2: coverity complains dead codesSteven Luong1-14/+11
Coverity complains dead codes in 2 places due to a recent commit as pointed out in Fixes. The dead codes are if (seed < L2_BD_ID_MAX % 2) is_seed_low = 1; and if (is_seed_low) seed += (2 * (i % 2) - 1) * i; seed can never be less than (L2_BD_ID_MAX % 2). Consequently, is_seed_low is always 0. There is also other problem. The inner loop is iterating only once. The fix is to greatly simplify the code to generate a random bd_id.

2022-06-29classify: use 32 bits hashBenoît Ganne3-12/+10
classify hash used to be stored as u64 in buffer metadata, use 32 bits instead: - on almost all our supported arch (x86 and arm64) we use crc32c intrinsics to compute the final hash: we really get a 32-bits hash - the hash itself is used to compute a 32-bits bucket index by masking upper bits: we always discard the higher 32-bits - this allows to increase the l2 classify buffer metadata padding such as it does not overlap with the ip fib_index metadata anymore. This overlap is an issue when using the 'set metadata' action in the ip ACL node which updates both fields Type: fix Change-Id: I5d35bdae97b96c3cae534e859b63950fb500ff50 Signed-off-by: Benoît Ganne <bganne@cisco.com>

2021-02-09l2: crash on l2_input_is_xconnectSteven Luong1-10/+8
Running vpp without any interface configured and then invoking the binary-api l2_xconnect_dump causes vpp to crash in l2_input_is_xconnect due to l2input_main.configs has no memory allocated to it, not even for the local interface which exists all the times. The reason that l2input_main.configs has no memory allocated to it was due to gerrit patch 29232 which took out a line in l2input_init /* Create the config vector */ vec_validate (mp->configs, 100); The fix is to iterate through l2input_main.configs for each interface in l2 to call l2_input_is_xconnect when dumping l2_xconnect interfaces.
