Detection of signal trampolines for handlers that set the
|
|
|
|
|
SA_RESTORER flag is in general not possible. Unfortunately this is
|
|
|
|
|
what the GNU C Library has been doing for quite some time now.
|
|
|
|
|
However, as of version 2.1.2, the GNU C Library uses signal
|
|
|
|
|
trampolines (named __restore and __restore_rt) that are identical
|
|
|
|
|
to the ones used by the kernel. Therefore, these trampolines are

supported too. */

/* We must be careful with modifying the program counter. If we
|
|
|

|
just interrupted a system call, the kernel might try to restart
|
|
|
|
|
it when we resume the inferior. On restarting the system call,
|
|
|
|
|
the kernel will try backing up the program counter even though it
|
|
|
|
|
no longer points at the system call. This typically results in a
|
|
|
|
|
SIGSEGV or SIGILL. We can prevent this by writing `-1' in the
|
|
|
|
|
"orig_eax" pseudo-register.
|
|
|
|
|
|
|
|
|
|
Note that "orig_eax" is saved when setting up a dummy call frame.
|
|
|
|
|
This means that it is properly restored when that frame is
|
|
|
|
|
popped, and that the interrupted system call will be restarted
|
|
|
|
|
when we resume the inferior on return from a function call from
|
|
|
|
|
within GDB. In all other cases the system call will not be
|
|

restarted. */

/* Linux kernel shows PC value after the 'int $0x80' instruction even if
|
|
|
|
|
inferior is still inside the syscall. On next PTRACE_SINGLESTEP it will
|
|
|
|
|
finish the syscall but PC will not change.
|
|
|
|
|
|
|
|
|
|
Some vDSOs contain 'int $0x80; ret' and during stepping out of the syscall
|
|
|
|
|
i386_displaced_step_fixup would keep PC at the displaced pad location.
|
|
|
|
|
As PC is pointing to the 'ret' instruction before the step
|
|
|
|
|
i386_displaced_step_fixup would expect inferior has just executed that 'ret'
|
|
|
|
|
and PC should not be adjusted. In reality it finished syscall instead and
|
|
|
|
|
PC should get relocated back to its vDSO address. Hide the 'ret'
|
|
|
|
|
instruction by 'nop' so that i386_displaced_step_fixup is not confused.
|
|
|
|
|
|
|
|
|
|
It is not fully correct as the bytes in struct displaced_step_closure will
|
|
|
|
|
not match the inferior code. But we would need some new flag in
|
|
|
|
|
displaced_step_closure otherwise to keep the state that syscall is finishing
|
|
|
|
|
for the later i386_displaced_step_fixup execution as the syscall execution
|
|
|
|
|
is already no longer detectable there. The new flag field would mean
|
|
|
|
|
i386-linux-tdep.c needs to wrap all the displacement methods of i386-tdep.c
|
|
|
|
|
which does not seem worth it. The same effect is achieved by patching that
|
|
|
|
|
'nop' instruction there instead. */
