Revision 1.20 / (download) - annotate - [select for diffs], Thu Oct 15 22:30:34 2020 UTC (3 years, 6 months ago) by rin

For cpu_jump_onfault() in data_abort_handler(), stop returning
hard-coded EFAULT and use return value from uvm_fault() instead.

There are some paths that do not call uvm_fault():

(1) For fatalabort case, use EFAULT as before.
(2) When va range is invalid, use EFAULT instead of EINVAL.

These change fixes bytes_transfer_eof_* tests in
sys/lib/libc/sys/t_ptrace_wait*.

Note that without (2) above, some tests like
sys/lib/libc/sys/t_wait:write_error become newly failing.

I've confirmed that there's no new regression in full ATF run.

OK ryo
