| 1.11 |
| 07-Jul-2023 |
riastradh | crashme(9): New crash methods with raised ipl or kpreempt disabled.
|
| 1.10 |
| 22-Sep-2022 |
riastradh | crashme(9): Clarify description of kernel_lock_spinout.
|
| 1.9 |
| 21-Sep-2022 |
riastradh | crashme(9): Fix crashme_add return value to match comment.
XXX Why do this and crashme_remove return -1 instead of an error code
like essentially everything else in the kernel?
|
| 1.8 |
| 21-Sep-2022 |
riastradh | crashme(9): Use sysctl mib numbers, not node pointers.
The node pointers are not stable across insertions of siblings,
because they are pointers into arrays that may be reallocated and
moved elsewhere.
XXX Need to audit the tree for other bugs of this class, or change
sysctl(9) so it returns stable node pointers.

| 1.7 |
| 30-Aug-2022 |
riastradh | crashme(9): New debug.crashme.mutex_recursion method.
Takes a lock twice. Set it to 1 for adaptive lock, 2 for spin lock.
|
| 1.6 |
| 16-Aug-2022 |
riastradh | crashme(9): New kernel_lock_spinout crasher.
This assumes that something will eventually try to take the kernel
lock and, after spinning for a while, spin out and crash -- so for
now it's only enabled under LOCKDEBUG, without which the kernel lock
spins forever.
|
| 1.5 |
| 27-Nov-2021 |
riastradh | kern: Add debug.crashme.null_jump.
|
| 1.4 |
| 07-Sep-2021 |
riastradh | New crashme sysctl to enter ddb directly.
|
| 1.3 |
| 23-Apr-2020 |
rin | Fix outdated comment. We've enabled crashme for non-DEBUG kernels.
|
| 1.2 |
| 13-Jan-2019 |
tnn | branches: 1.2.2; 1.2.6; 1.2.14;
clang does not like to deref a null pointer unless it is qualified volatile
|
| 1.1 |
| 09-Jan-2019 |
mrg | crashme: a framework to test kernel faults.
so far, only a basic panic() and null deref nodes are added.
with options DEBUG, one can now use:
# sysctl -w kern.crashme_enable=1
# sysctl -w kern.crashme.panic=1
# sysctl -w kern.crashme.null_deref=1
to trigger a crash. crashme_enable must be set to 1 before any
of the nodes will be writeable.
supports dynamic additional/removal of crashme nodes.
(obsoletes kern.panic_now, which will be removed later.)
