https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D212607 --- Comment #15 from commit-hook@freebsd.org --- A commit references this bug: Author: badger Date: Sat Mar 25 13:33:25 UTC 2017 New revision: 315949 URL: https://svnweb.freebsd.org/changeset/base/315949 Log: MFC r313992, r314075, r314118, r315484: r315484: ptrace_test: eliminate assumption about thread scheduling A couple of the ptrace tests make assumptions about which thread in a multithreaded process will run after a halt. This makes the tests less portable across branches, and susceptible to future breakage. Instead, twiddle thread scheduling and priorities to match the tests' expectation. r314118: Actually fix buildworlds other than i386/amd64/sparc64 after r313992 Disable offending test for platforms without a userspace visible breakpoint(). r314075: Fix world build for archs where __builtin_debugtrap() does not work. The offending code was introduced in r313992. r313992: Defer ptracestop() signals that cannot be delivered immediately When a thread is stopped in ptracestop(), the ptrace(2) user may requ= est a signal be delivered upon resumption of the thread. Heretofore, those signals were discarded unless ptracestop()'s caller was issignal(). Fix this = by modifying ptracestop() to queue up signals requested by the ptrace us= er that will be delivered when possible. Take special care when the signal is SIGKILL (usually generated from a PT_KILL request); no new stop events should= be triggered after a PT_KILL. Add a number of tests for the new functionality. Several tests were authored by jhb.
