| Summary | 0002094: aborting gnunet-service-vpn fails (assertion at mesh_api.c:1296). | ||||
| Description | Not only do I get this assertion failure, but also the process then fails to terminate: Jan 21 16:41:13-004966 vpn-26767 ERROR Assertion failed at mesh_api.c:1296. Jan 21 16:41:13-004993 vpn-26767 ERROR Assertion failed at mesh_api.c:1296. Jan 21 16:41:13-004998 vpn-26767 ERROR Assertion failed at mesh_api.c:1296. | ||||
| Steps To Reproduce | I ran mesh, exit and vpn services, then used the usual wget PLUS ping (to send ICMP traffic) -- neither of which worked. Then, I first stopped the mesh service. When I then tried to stop VPN, the process printed the assertion failures and did not shutdown on CTRL-C. | ||||
| Additional Information | Looks like the 'reconnect_task' of MESH is not being canceled properly: (gdb) ba #0 0x00007f17e0e138b3 in __select_nocancel () at ../sysdeps/unix/syscall-template.S:82 #1 0x00007f17e14f2172 in GNUNET_NETWORK_socket_select (rfds=0x22048d0, wfds=0x21fc250, efds=0x0, timeout=...) at network.c:1213 #2 0x00007f17e14fdd1a in GNUNET_SCHEDULER_run (task=0x7f17e150956a <service_task>, task_cls=0x7fffccd5e2c0) at scheduler.c:845 #3 0x00007f17e150b00c in GNUNET_SERVICE_run (argc=1, argv=0x7fffccd5e518, serviceName=0x40a6bd "vpn", opt=GNUNET_SERVICE_OPTION_NONE, task=0x4098bc <run>, task_cls=0x0) at service.c:1712 #4 0x0000000000409ea7 in main (argc=1, argv=0x7fffccd5e518) at gnunet-service-vpn.c:2673 (gdb) ba #0 0x00007f17e0e138b3 in __select_nocancel () at ../sysdeps/unix/syscall-template.S:82 #1 0x00007f17e14f2172 in GNUNET_NETWORK_socket_select (rfds=0x22048d0, wfds=0x21fc250, efds=0x0, timeout=...) at network.c:1213 #2 0x00007f17e14fdd1a in GNUNET_SCHEDULER_run (task=0x7f17e150956a <service_task>, task_cls=0x7fffccd5e2c0) at scheduler.c:845 #3 0x00007f17e150b00c in GNUNET_SERVICE_run (argc=1, argv=0x7fffccd5e518, serviceName=0x40a6bd "vpn", opt=GNUNET_SERVICE_OPTION_NONE, task=0x4098bc <run>, task_cls=0x0) at service.c:1712 #4 0x0000000000409ea7 in main (argc=1, argv=0x7fffccd5e518) at gnunet-service-vpn.c:2673 (gdb) print *pending_timeout $2 = {next = 0x0, callback = 0x7f17e1920d36 <reconnect_task>, callback_cls = 0x21fc840, read_set = 0x0, write_set = 0x0, id = 431, prereq_id = 0, timeout = {abs_value = 1327161073101}, reason = GNUNET_SCHEDULER_REASON_STARTUP, priority = GNUNET_SCHEDULER_PRIORITY_DEFAULT, read_fd = -1, write_fd = -1, lifeness = 1} (gdb) print *pending Cannot access memory at address 0x0 | ||||

| child of | 0002064 | closed | Christian Grothoff | new VPN service (working with new exit/dns services) needs to be fully implemented and tested |
|
|
gnunet-daemon-exit also hangs, I suspect for the same reason. |
|
|
This report most likely represents 2 bugs -- the assertion failure AND the failure to cancel a task. |
|
|
Same as 0002090, fixed in r19335. |
