sgsn: Free MM context after receiving a Detach Request
On a Detach/Re-attach cycle the Address Sanitizer detected a use-after-free kind of problem. That is because we tried to destroy the LLME twice. The first time it is destroyed as part of the Detach handling ans the second time it is destroyed as part of destroying the old MM context. In case the GPRS GMM detach message is lost the SGSN needs to reply besides not having a MM entry. The alternative would have been to add NULL checks for all usages of ctx->llme which would not have helped with the readability. Sponsored-by: On-Waves ehf
