* 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.

* sverker/ets-auto-unfix-delete-race/OTP-15109:
erts: Fix race between ets table deletion and auto-unfix
|
|
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.

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.

do not call abort_signal_task() with invalid data

This was changed in the logger in 8aa64c90ddd20ec0ca8cc5fe92a6124324c51da5.

These were actually wrong in erl_db.c:
count_trap\0

* lukas/erts/fix-scheduler-data-sched-out-bug/OTP-13123:
erts: Make sure scheduler_data is set
|
|

|
If scheduler_data is not set correctly on normal schedulers
the code in erts_schedule_time_break and possibly others
will trigger asserts.

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.

* lukas/erts/cpu_time_thread/OTP-15090:
erts: Make cpu_timestamp use per thread on Linux

of same named table.
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
in tb->common.owned.

epmd: allow alternative to dns resolving for nodename
|

This makes it possible to create a custom integration with a
key-value store for example. The key would then point to the
actual address. You would have to write your own epmd module
to make use of that feature.
