3.4.2.4. GDB module_init add trap instruction
This is another possibility: we could modify the module source by adding a trap instruction of some kind.
This appears to be described at: https://www.linuxjournal.com/article/4525
But it refers to a gdbstart
script which is not in the tree anymore and beyond my git log
capabilities.
And just adding:
asm( " int $3");
directly gives an oops as I’d expect.
