Since 2.5, an array of GPC is provided to replace legacy gpc0/gpc1. src_inc_gpc is a sample fetch which is used to increment counters in this array. A crash occurs if src_inc_gpc is used without any previous track-sc rule. This is caused by an error in smp_fetch_sc_inc_gpc(). When temporary stick counter is created via smp_create_src_stkctr(), table pointer arg value used is not correct : it points to the counter ID instead of the table argument. To fix this, use the proper sample fetch second arg. This can be reproduced with the following config : acl mark src_inc_gpc(0,<table>) -m bool tcp-request connection accept if mark This should be backported up to 2.6. |
