memory overwrite error in UDPNetHandler
---------------------------------------
Key: TS-69
URL: https://issues.apache.org/jira/browse/TS-69
Project: Traffic Server
Issue Type: Bug
Components: Core
Reporter: John Plevyak
Assignee: John Plevyak
The UDPNetHandler is allocated with sizeof(NetHandler) (a smaller object).
The interesting thing is that it is being overwritten with statistics and is
overwriting other things. This will not get
caught by valgrind because it uses a custom allocator for thread local data.
This mechanism needs to be rethought.
In any case here are the offending lines are:
The allocattion:
UnixUDPNet.cc: udpNetHandler_offset =
eventProcessor.allocate(sizeof(NetHandler));
The second allocation:
RecProcess.cc: if ((ethr_stat_offset = eventProcessor.allocate(num_stats *
sizeof(RecRawStat))) == -1) {
read.write 1:
#1 0x000000000071e30d in raw_stat_sync_to_global (rsb=0xd2d0a0, id=3) at
RecProcess.cc:93
93 total.sum += ink_atomic_swap64(&(tlp->sum), 0);
read.write 2:
at UnixUDPNet.cc:1261
1261 trigger_event = e;
and
at UnixUDPNet.cc:1299
1299 ink_assert(trigger_event == e && event == EVENT_POLL);
