Highlights of the week 15th Aug`22 from Ankit Kumar Aman:


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
  4. Reviewed PRs:  https://github.com/magma/magma/pull/13423/, https://github.com/magma/magma/pull/13323, https://github.com/magma/magma/pull/13508, https://github.com/magma/magma/pull/13332, https://github.com/magma/magma/pull/13423

Highlights of the week 8th Aug`22 from Ankit Kumar Aman:


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:

  1. Incorporated review comments on PR, https://github.com/magma/magma/pull/13335
  2. Locally brought up the Orc8r based subscriber DB. Issue was reported that on execution of basic attach detach test case from s1ap tester was resulting into Authentication Failure with emm_cause "sync failure"
    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.

Highlights of the week 26th July`22 from Pruthvi:

  1. As part of MOCN-GW design, added design for handling reset procedure
  2. IPv6 data test cases in PR https://github.com/magma/magma/pull/12646 are not working on master code. Debugging in progress

Highlights of the week 25th July`22 from Rashmi:

  •  As part of issue, https://github.com/magma/magma/issues/11191 after converting C structure ue_description_t to protobuf structure UeDescription, memory leaks were occurring. Fixed these leaks in both unit test cases and end2end test cases
  • Locally bringing up Orc8r and AGW and register AGW with Orc8r cloud.

Highlights of the week 6th July`22 from Vikram:

  1. Working on C++ migration activity for renaming c to cpp in mme_app and nas.

Highlights of the week 4th July`22 from Ankit Kumar Aman:

Highlights of the week 4th July`22 from Rashmi: 

  1. As part of c++ migration, completed porting of hashlist, state_ue_ht to protobuf ma. Manually verified the changes. Once previous PRs are merged. I shall create new PR.
  2. As part of issue, https://github.com/magma/magma/issues/9902. As part of mme restart I did some analysis. Got to know that mme2associd was not updated. Modifying the code based on this observation didn't seem to work. 
  3. Provided the fixes for the issue, https://github.com/magma/magma/issues/13086
  4. Reviewed the PRs, https://github.com/magma/magma/pull/13103 and https://github.com/magma/magma/pull/13142


Highlights of the week 29th June`22 from Vikram:

  1. Working on C++ migration activity for renaming c to cpp in mme_app.

Highlights of the week 28th June`22 from Rashmi: 

  1. Incorporated review comments on PR, https://github.com/magma/magma/pull/12965/

  2. As part of c++ migration, completed porting of hashlist, mme_ue_id_imsi_htbl to protobuf map. Shall raise PR for the same

  3. 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.

Highlights of the week 28th June`22 from Pruthvi:

  1. Started working on C++ migration activity for SPGW task. Fixed return type mismatch errors in all the files under SPGW task
  2. Changed file extension to .cpp and .hpp which is resulting into lot of compilation errors and warnings. Working on fixing them
  3. IPv6 PR https://github.com/magma/magma/pull/13010 is merged to master. But vms were not coming up on local VMs, updated quick start guide to add IPv6 address range in /etc/vbox/networks.con
