change other SMBERROR() calls to SMBIODEBUG() - they are only useful when
debugging, and avoids spamming console/system logs with messages triggerable
from userland
do the translation ourselves (if the tty didn't do it for us).
Add debugging to track functions that change tty state.
Fixes PR 20834 by Stephen Borrill.
pthread_spin_t variable (4 bytes) but telling read that they were
reading sizeof(struct pthread_spinlock_st) (12 bytes). This led to
overwriting other things on the stack, like the return address. Oops.
Fix by changing READ call here (and elsewhere, for future safety) to:
READ(,, &variable, sizeof(variable))
instead of
READ(,, &variable, sizeof(type)).
Fixes a crash in gdb when running "thread examine all" reported by
Bill Studenmund.
try to quit or stop the program right at the moment after the it
sends a TSTP to init, move the kill(1, TSTP) to right after we
block most signals, instead of doing it just before.
2) To add TSTP to the signals we ignore. Once we start halting, it
really is not safe to try to stop at all. You can't change your
mind halfway through -- init will already be stopped and a TERM
will have been sent to everything on the system within
milliseconds of starting.
3) Adjust one comment for TNF
-A address Dumps the vm_amap structure found at address.
-E address Dumps the vm_map_entry structure found at address.
-S address Dumps the vmspace structure found at address.
-V address Dumps the vm_map structure found at address.
This required reorganizing the code a little, which led to some
cleanup (yay!). These new methods are executed without any extra
privileges, so you need read access on /dev/mem or on the kernel core
into which you are digging.
This should be useful for, eg, examining amaps are corrupt when being
destroyed, which can cause a kernel panic (and, hence, are no longer
connected to a map entry, or the map entry is no longer connected to a
vm_map/vmspace).
The options in the man page have also been reorganized.
