2 years agoHold a read lock on the map while copying out data during a sysctl(2) call

Hold a read lock on the map while copying out data during a sysctl(2) call
to prevent another thread from unmapping the memory and triggering
an assertion or even corrupting random physical memory pages.

This fix is similar to the change in uvm_glue.c rev. 1.74.  However in this
case we need to be careful since some sysctl(2) calls look at the map of

claudio [Fri, 11 Mar 2022 10:05:38 +0000 (10:05 +0000)]
Revert part of rev 1.293. Using cursig() to deliver masked signals
to the debugger can cause a loop between the debugger and cursig()
if the signal is masked. cursig() has no way to know which signal
was already delivered to the debugger and so it delivers the same
signal over and over again.

Instead handle traps to masked signals directly in trapsignal. This
is what rev 1.293 was mostly about. If SIGTRAP was masked by the
process breakpoints no longer worked since the signal deliver to
the debugger did not happen. Doing this case in trapsignal solves
both the problem with the loop and the delivery of masked traps.
