[PATCH] bssgp: Fix call to llist_entry in fc_queue_timer_cfg
by Jacob Erlbeck 05 May '15

05 May '15

Currently the DL sometimes hangs and sometimes a lot of messages (still not able to send PDU) are logged. This is caused by an invalid timer delay computation, setting msecs either to 0 or to some big value. This is due to an '&' operator at the wrong place, accessing some parts in fc instead of the first element of the list. This commit fixes that issue.

[PATCH] opensgsn: Replace some TODOs with error paths and fix compiler warning
by Mike McTernan (wavemobile) 01 May '15

01 May '15

openggsn: Check return codes and take error paths on failure. Return early when socket() returns -1, and check return codes where indicated by some TODOs. This removes 2 TODOs and fixes a compiler warning about assignment to a variable which then isn't used.
