* Only build the libmagic build-tools if MK_FILE != noAlex Richardson2017-11-131-1/+4

* Only clear a pending thread event if one is pending.John Baldwin2017-11-131-26/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a panic when attaching to an already-stopped process after r325028. While here, clean up a few other things in the control flow of the 'sendsig' section: - Only check for P_STOPPED_TRACE rather than either of P_STOPPED_SIG or P_STOPPED_TRACE for most ptrace requests. The signal handling code in kern_sig.c never sets just P_STOPPED_SIG for a traced process, so if P_STOPPED_SIG is stopped, P_STOPPED_TRACE should be set anyway. Remove a related debug printf. Assuming P_STOPPED_TRACE permits simplifications in the 'sendsig:' block. - Move the block to clear the pending thread state up into a new block conditional on P_STOPPED_TRACE and handle delivering pending signals to the reporting thread and clearing the reporting thread's state in this block. - Consolidate case to send a signal to the process in a single case for PT_ATTACH. The only case that could have been in the else before was a PT_ATTACH where P_STOPPED_SIG was not set, so both instances of kern_psignal() collapse down to just PT_ATTACH.

| | | | | | | | | | | | | | There were two things wrong. First, the wrong path was listed in .PATH statement. Second, BOOTSRC wasn't yet defined for the .PATH, so it didn't properly add it.
