5 years agoIntroduce __rseq_cs_ptr_array, rename __rseq_table to __rseq_cs
Mathieu Desnoyers [Wed, 13 Mar 2019 17:20:42 +0000 (13:20 -0400)] 
Introduce __rseq_cs_ptr_array, rename __rseq_table to __rseq_cs

The entries within __rseq_table are aligned on 32 bytes due to
linux/rseq.h struct rseq_cs uapi requirements, but the start of the
__rseq_table section is not guaranteed to be 32-byte aligned. It can
cause padding to be added at the start of the section, which makes it
hard to use as an array of items by debuggers.

Considering that __rseq_table does not really consist of a table due to
the presence of padding, rename this section to __rseq_cs.

Create a new __rseq_cs_ptr_array section which contains 64-bit packed
pointers to entries within the __rseq_cs section.

Add __rseq_exit_point_array section for debuggers

Knowing all exit points is useful to assist debuggers stepping over the
rseq critical sections without requiring them to disassemble the content
of the critical section to figure out the exit points.
