the eeprom on common types of memory modules. The specifications are
displayed during boot and can later be queried in the hw.spdmemN sysctl
subtree. Stub driver written by Nicolas Joly and greatly improved upon by
Paul Goyette. From PR 36745, with additional improvements by Paul and me.

+ remove case '?' in switch() before default

+ use constants EXIT_SUCCESS/EXIT_FAILURE instead of 0/1

(semu + seminfo.semmnu) is wrong, because the type of semu is int*.
You could fix the offset ((char *)semu + seminfo.semusz), but simply
putting the condvars first is more clear.
FALSE -> false, TRUE -> true, boolean_t -> bool, int -> bool when
appropriate, include stdbool.h . proplib.h no longer provides boolean_t,
so it is necessary to change to bool.
From Tom Spindler (dogcow@).
VOP_LOOKUP ignores LOCKPARENT completely, so make this ignore it also.
XXX: tested only with rump, but I can't really see how this worked
at all before
in its own header file to be included by dkio.h. Fixes breakage due to
pollution from proplib.h in programs which include ioctl.h. Tested and OK
by dogcow@.
userland, deeply nested arrays and dictionaries can easily overflow
the kernel stack and thereby force a panic.
Fix the internalizer and prop_object_release to use a separate call
stack and alter the dictionary and array handling to not recurse on
the C stack. The default stack has an inline depth of 16 elements,
which should keep the overhead reasonable.
This issue was found by Pavel Cahyna and Jachym Holecek.
Additionally add a limit for prop_object_copyin_ioctl to prevent user
programs from temporary allocating unbound amount of kernel memory.
Allow malloc to fail so that tight loops of userland processes can't
force panics by exhausting the kernel map.
Tested with the sample exploit of Jachym, his test suite and reviewed
by himself (initial patch), Christos Zoulas and Jason Thorpe.
