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

2018-05-22erts: Let allocator pooled_tree also use Age OrderSverker Eriksson
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.
