2018-08-03erts: Fix seq_trace to not clear token for system messagesLukas Larsson
A lot of erts internal messages used behind APIs to create non-blocking calls, e.g. port_command, would cause the seq_trace token to be cleared from the caller when it should not. This commit fixes that and adds asserts that makes sure that all messages sent have to correct token set. Fixes: ERL-602

which only existed in a patched version of valgrind (by pan) no longer used. Instead we use standard VALGRIND_PRINTF which will end up like this if valgrind log format is XML and valgrind version >= 3.9: <clientmsg> <tid>7</tid> <threadname>3_scheduler</threadname> <text>Test case #20 ei_encode_SUITE:test_ei_encode_long/1 </text> </clientmsg> Note the extra trailing whitespace that may occure before </text>.

2018-07-13Fix a rare crash when matching on literal mapsJohn Högberg
When matching on a literal map, the map is placed into the general scratch register first. This is fine in isolation, but when the key to be matched was in a Y register it would also be placed in the scratch register, overwriting the map and crashing the emulator.

2018-07-12erts: Fix bug in crash dump generationSverker Eriksson
Symptom: emulator core dumps during crash dump generation. Problem: erts_dump_lit_areas did not grow correctly to always be equal or larger than number of loaded modules. The comment about twice the size to include both curr and old did not seem right. The beam_ranges structure contains *all* loaded module instances until they are removed when purged.
2018-07-10erts: Fix buggy calls to erts_sys_explicit_8bit_getenvSverker Eriksson
Two of them only affect valgrind builds and the one for ERL_CRASH_DUMP_NICE seems benign. Return value changed in c2d70945dce9cb09d5d7120d6e9ddf7faac8d230 old -> new -1 -> 0 not found 0 -> 1 found ok 1 -> -1 found but too big

* john/erts/merge-OTP-15067: Don't enqueue system tasks if target process is in fail_state Fix erroneous schedule of freed/exiting processes Fix deadlock in run queue evacuation Fix memory leak of processes that died in the run queue
2018-06-27Move to a dirty scheduler even when we have pending system tasksJohn Högberg
When a system task was enqueued on a process between being scheduled and the check altered in this commit, we'd run dirty code on a normal scheduler as the RUNNING_SYS flag wasn't set and we wouldn't migrate back. This change migrates us to a dirty scheduler instead, which will immediately bounce us back to a normal scheduler where RUNNING_SYS will be set appropriately. This is caught fairly reliably by process_SUITE:system_task_failed_enqueue on machines with a lot of cores.

2018-06-14Don't enqueue system tasks if target process is in fail_stateJohn Högberg
The fail state wasn't re-checked in the state change loop; only the FREE state was checked. In addition to that, we would leave the task in the queue when bailing out which could lead to a double-free. This commit backports active_sys_enqueue from master to make it easier to merge onwards.
2018-06-14Fix erroneous schedule of freed/exiting processesJohn Högberg
When scheduled out, the process was never checked for the FREE state before rescheduling, which meant that a system task could sneak in and cause a double-free later on.

Seen symptom: handle_process_info() called with is_alive=1 on exiting process, reading broken Process.u.initial.module atom overwritten by Process.u.terminate pointer. Solution: Let erts_proc_sig_handle_incoming() do nothing if process is already exiting.

2018-06-07erts: Fix race between ets table deletion and auto-unfixSverker Eriksson
Bug exists since ets-refs were introduced in 20.0 0d6dc895744c34c9c52fd42f4801a8a941864ae3. Problem: 1. Process A fixates table T. 2. Process B starts deleting table T (either by ets:delete or exit) and does tid_clear(). 3. Process A exits and does proc_cleanup_fixed_table() and get NULL from btid2tab() and deallocates DbFixation. 4. Process B continues deleting table in free_fixations_locked() and finds the deallocated DbFixation in the fixing_procs tree. Solution: Wait with tid_clear() until after free_fixations_locked() has traversed the fixing_procs tree.

2018-06-05erts: Fix broken signal queueSverker Eriksson
broken on master by 613cde66c25464121f2f6dace99782bad0e07d9b Scenario: proc_queue_signal() fails to send switched pending signal due to state & ERTS_PSFLG_FREE, and then calls erts_proc_sig_send_monitor_down() to enqueue to self followed by sig_enqueue_trace_cleanup() that destroyed 'next' pointer of enqueued signal. Solution: Switch order and do sig_enqueue_trace_cleanup() first.
