* john/erts/fix-literal-map-elements/OTP-15184:
Fix a rare crash when matching on literal maps
|
|
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.

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
|
|
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.

|
|
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.
|
|
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.

erts: Fix race between ets table deletion and auto-unfix
|
|
* sverker/process-info-exiting:
erts: Fix incoming signal handling for exiting process
|
|
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.

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.

|

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.

if configured for the allocator. This was not implemented
and pooled_tree always used address order first fit.
The "problem" was as a carrier can be part of both the pooled tree
(of its owner) and the allocation tree (of a foreign instance)
at the same time. Solved by duplicating 'birth_time' in both
AOFF_RBTree_t nodes for each carrier.
Blocks still cannot use age order and does not pay
any memory cost for birth_time.

If other process does ets:delete
before ets:new has completely finished and done save_owned_table
then ets:delete might do delete_owned_table and deref wild pointers
