Also fixed the implementation of default_pager_paging_storage_new in proxy
def pager to call into default_pager_paging_storage_new.
We can fast track the simplification of the RPC ABI for x86_64 if we don't have
MACH_MSG_TYPE_STRING used in RPCs which forces msgt_size to use more than 8
bits.

default_pager_paging_storage RPC.
This brings us a bit closer to having all types' msgt_size representable
with a single byte. We will be able to avoid mach_msg_type_long_t
entirely for x86_64 since mach_msg_type_t can represent long types using
a separate field.

The default_pager_paging_storage RPC has already it more than 20 years
ago. Given that we want to change the type of default_pager_filename_t
to use c_string, we can just remove the unused RPC.
Tested that swapon/swapoff still work with the new binaries.

Also update the crash_dump_task RPC since it gets the subcode from the
signal details in Glibc.
This should fix the existing build error.

function declarations.
Most of the changes land in one of these buckets:
* Removed unused declarations.
* Used (void) to represent no parameters instead of () which means an
undeterminate number of parameters.
* Included missing header files whenever necessary (stdlib.h,
sys/mman.h, etc)
* Typedefed function pointers to be able to fully declare the parameter
types.
* Added declarations of library functions that are used elsewhere
(example is libps/ps.h).
* Made functions static whenever they are only used in that file.
* Forwarded declarations of some methods that were made static.

To allow e.g. libubsan to detect it should be extra cautious.

We need to keep ds locked, otherwise it might disappear before we have a
chance to broadcast the condition.

Shifting (signed) 1 to left 31 positions is undefined behavior. So make
this an unsigned so it becomes defined behavior.

instead of just exiting: better print a backtrace so we get to know what
happened.
|
|
|
|
|
| |
So we get to know why the system gets stuck if mach-defpager happens to
die.

Now that the RPCs have const, this forces us cleaning our const-meant
functions.
|
|
|
|
|
| |
This follows mig's cf4bcc3f1435 ("Also add const qualifiers on server
side")
|
|
|
|
| |
No actual behavior change.

wire_task_self() was duplicating mach-defpager's wire_all_memory(), we
can just make mach-defpager now use the former (and not mlockall
either). Also pci-arbiter and rumpdisk can use it.
|
|
|
|
| |
* mach-defpager/main.c (main): After mlockall, report error from errno, not the value returned by mlockall.

glibc is removing its malloc hooks, but gnumach now has support for
mlockall, which we can just use instead of kalloc/kfree.
* mach-defpager/main.c (main): Call mlockall.
* mach-defpager/kalloc.c: Remove.
* mach-defpager/kalloc.h: Remove.
* mach-defpager/default_pager.c: Use malloc/free instead of
kalloc/kfree.

* mach-defpager/default_pager.c (default_pager): Drop disabled cthreads
calls.
* pfinet/kmem_cache.c: Fix comment.
