Highlights of the week 23rd Aug`22 from Pruthvi:

  1. Debugged test_ipv6_non_nat_dp_ul_tcp.py TC which is failing on CI with Christian Kramer from TNG. Found the following two issues:
    1. UE`s IPv6 address was getting added to eth3 interface of test vm with netmask 0. Fixed the issue.
    2. Sometimes neighbor between dev and trfserver was getting delayed or not happening at all. Earlier Pravin had given a fix for similar issue. But in this fix after receiving Neighbor Solicit msg from trfserver, agw was forwarding this msg to UE. UE would reply with Neighbor Adv msg. After this step, UE`s ipv6 address on eth3 interface of test vm used to become invalid and the test used to fail with "Cannot assign this address" error on the test VM. Christian Kramer fixed this issue so that the Neighbor Solicit msg from trfserver will be handled in dev VM itself and it will not be forwarded to UE.
    3. With the above fixes, a draft PR https://github.com/magma/magma/pull/13669 is created to verify if it works on CI. The test has passed in 3 consecutive runs. Will monitor the test for few more days before days.
  2. Started working c++ migration of files under nas/esm folder 
  3. Reviewed PRs:  https://github.com/magma/magma/pull/13508

Highlights of the week 22nd Aug`22 from Rashmi:

  1. Incorporated review comments on PR, https://github.com/magma/magma/pull/13508
  2. As part of cpp migration, working on porting eNB context from C structure to protobuf structure. After porting unit test case, GenerateUEContextReleaseCommand was failing because we added s1ap_enb_state as enum, previously it was integer, due to this change we need to add newly added parameter to encoded file. This issue is fixed. Coding is completed, need to validate the changes and cleanup the code.

Highlights of the week 9th  Aug`22 from Pruthvi:

  1. As part of MOCN-GW design:
    1. Added design for handling success and failure scenarios during S1 and X2 handovers
  2. Retested IPv6 data test cases in PR https://github.com/magma/magma/pull/12646 which were earlier not working on master code. Without any local changes the tests are now working individually on multiple runs and also when added as part of integ tests. PR is merged to master.
  3. Working on IPv6 dedicated bearer test cases in PR https://github.com/magma/magma/pull/12892

Highlights of the week 2nd  Aug`22 from Pruthvi:

  1. As part of MOCN-GW design:
    1. Added design for handling failure scenarios for S1 setup, Initial attach, Idle mode and Reset procedures
    2. Modified handling of S1 setup procedure between MOCN-GW and MME. Updated the design to use preconfigured enb-id(per MME) at MOCN-GW instead of same Id for all MMEs
    3. Working on the design of HO scenarios
  2. IPv6 data test cases in PR https://github.com/magma/magma/pull/12646 are not working on master code. IPv6 data TC works if iperf is run between dev vm and trf vm on eth3 interface address prior to running the s1ap ipv6 test. The static ipv6 addresses configured on eth3 interfaces of dev and trf server vms become reachable when iperf is run between the 2 vms. Due to this ipv6 data test works if executed after running iperf. Trying to analyze why eth3 interface ipv6 addresses are not reachable if iperf is not run.
  3. Reviewed PRs:  https://github.com/magma/magma/pull/13318, https://github.com/magma/magma/pull/13332

Highlights of the week 1st Aug`22 from Rashmi:

    But in my setup authentication is successful, but mobilityd is not able allocate UE ip address because subscriber is not configured. Checking the dependency of mobilityd on subscriber for IP allocation
  3. As part of c++ migration, ported all c files to cpp for sgw_s8 module.

  • As part of issue, https://github.com/magma/magma/issues/9902 Analyzed the logs. From the logs it appears that mme is going through multiple scenarios like mme is handling multi UE and multi eNB with different types of procedures like request for handover, UE entering to idle state and back to active state; sctp disconnection. From logs I re-created few of scenario, but looks to be good.  Right now we shall replace assert with error log and return.
