[tickets] [opensaf:tickets] #3137 log: accessing unacked invocation list is not thread-safe
- **status**: review --> fixed - **Comment**: commit d3b3bd1fb4bb3afe5d8252641bc68029f91b69b3 (HEAD -> develop, origin/develop, ticket-3137) Author: Vu Minh Nguyen Date: Mon Jan 6 10:12:56 2020 +0700 log: fix segmentation fault in log agent [#3137] log agent did not protect the resource `unacked_invocations_ list` from accessing by multiple threads, so caused segmentation fault. This patch introduces a mutex in order to synchronize the access to that common resource. --- ** [tickets:#3137] log: accessing unacked invocation list is not thread-safe** **Status:** fixed **Milestone:** 5.20.01 **Created:** Fri Jan 03, 2020 09:49 AM UTC by Vu Minh Nguyen **Last Updated:** Mon Jan 06, 2020 03:16 AM UTC **Owner:** Vu Minh Nguyen Coredump is generated; here is part of the backtrace. ~~~ Program terminated with signal SIGSEGV, Segmentation fault. #0 std::list >::remove (__value=@0x7fff770051f8: 1024193, this=0x15f2930) at /usr/include/c++/4.8/bits/list.tcc:248 [Current thread is 1 (Thread 0x7f94914d4780 (LWP 7167))] ### BT ### #0 std::list >::remove (__value=@0x7fff770051f8: 1024193, this=0x15f2930) at /usr/include/c++/4.8/bits/list.tcc:248 #1 LogClient::RemoveTrack (inv=1024193, this=0x15f2890) at ./src/log/agent/lga_client.h:181 #2 LogClient::InvokeCallback (this=this@entry=0x15f2890, msg=msg@entry=0x7f9480001cf0) at src/log/agent/lga_client.cc:135 ~~~ --- Sent from sourceforge.net because opensaf-tickets@lists.sourceforge.net is subscribed to https://sourceforge.net/p/opensaf/tickets/ To unsubscribe from further messages, a project admin can change settings at https://sourceforge.net/p/opensaf/admin/tickets/options.
