The BUG_ON trace on this is quite interesting, unless I missed something: * do_path_lookup calls path_init_rcu, which sets the LOOKUP_RCU in nd->flags
* path_walk_rcu doesn't appear on the trace as it's inline, just link_path_walk appears. So link_path_walk is under path_walk_rcu called from do_path_lookup * now things get better: inside link_path_walk, it actually checks "if (nd->flags & LOOKUP_RCU)", and only under it it executes nameidata_drop_rcu, so the "BUG_ON(!(nd->flags & LOOKUP_RCU))" inside nameidata_drop_rcu shouldn't happen. Probably the flag is reset at some point under exec_permission which goes under aufs code, or something else (another concurrent code). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/713769 Title: natty 20110202, invalid opcode: 0000 [#1] SMP -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
