ftmemsim-valgrind/coregrind/m_syswrap/syswrap-ppc32-linux.c
Lubomir Rintel a21e890f82 Add close_range(2) support 
This is a system call introduced in Linux 5.9.

It's typically used to bulk-close file descriptors that a process inherited
without having desired so and doesn't want to pass them to its offspring
for security reasons. For this reason the sensible upper limit value tends
to be unknown and the users prefer to stay on the safe side by setting it
high.

This is a bit peculiar because, if unfiltered, the syscall could end up
closing descriptors Valgrind uses for its purposes, ending in no end of
mayhem and suffering.

This patch adjusts the upper bounds to a safe value and then skips over
the descriptor Valgrind uses by potentially calling the real system call
with sub-ranges that are safe to close.

The call can fail on negative ranges and bad flags -- we're dealing with
the first condition ourselves while letting the real call fail on bad
flags.

Perform a clone system call. clone is strange because it has
fork()-like return-twice semantics, so it needs special
handling here.
Upon entry, we have:
int (fn)(void*) in r3
void* child_stack in r4
int flags in r5
void* arg in r6
pid_t* child_tid in r7
pid_t* parent_tid in r8
void* ??? in r9
System call requires:
int $__NR_clone in r0 (sc number)
int flags in r3 (sc arg1)
void* child_stack in r4 (sc arg2)
pid_t* parent_tid in r5 (sc arg3)
?? child_tls in r6 (sc arg4)
pid_t* child_tid in r7 (sc arg5)
void* ??? in r8 (sc arg6)
Returns an Int encoded in the linux-ppc32 way, not a SysRes.
