pooka | branches: 1.7.48;
Wipe out the last vestiges of POOL_INIT with one swift stroke. In
most cases, use a proper constructor. For proplib, give a local
equivalent of POOL_INIT for the kernel object implementation. This
way the code structure can be preserved, and a local link set is
not hazardous anyway (unless proplib is split to several modules,
but that'll be the day).
tested by booting a kernel in qemu and compile-testing i386/ALL

pavel | branches: 1.5.8;
struct plistref does not reference other proplib data types, so split it
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@.

thorpej | branches: 1.4.2; 1.4.4; 1.4.12;
Alter the protocol impemented by prop_kern to allow for bi-directional
plist-based messages and to eliminate looping previously required to
receive a plist from the kernel:
- prop_dictionary_copyin_ioctl() and prop_dictionary_copyout_ioctl()
now take the cmd argument rather than the file open flag. The
read-ness or write-ness of an ioctl command is checked by these
routines to ensure that information is being passed to/from the
userland component properly.
- prop_dictionary_copyout_ioctl() now allocates the memory for the
XML plist on behalf of the userland component by way of uvm_mmap().
The XML plist is copied out to the newly-mapped anonymous region,
and the pointer returned via the plistref.
- prop_dictionary_recv_ioctl() is responsible for munmap()'ing the
region after parsing the XML plist into internal represenatation.
- A new prop_dictionary_sendrecv_ioctl() is added, allowing user space
code to send a dictionary to the kernel and receive one back as a
reply.
Update users of prop_kern for the API changes (Bluetooth).
This constitutes an ABI / protocol change -- but this will also be put
into NetBSD 4.0 so that the first proplib release will implement the new
scheme.

thorpej | Several changes to proplib:
- Arrays can now be externalized and internalized in the same way
dictionaries can.
- Add new "externalize to file" and "internalize from file" functions
to make reading a property list from a file and writing a property
list to a file more convenient.
- Many assertions in the object implementations are gone. Instead,
calling an accessor for one object type with a different object type
as an argument will return a suitable "invalid" value.
- prop_object_type() now returns a new PROP_TYPE_UNKNOWN value if called
with a NULL object.
- Externalized property lists now contain a reference to the Apple XML
plist DTD.
- Add a new prop_ingest(3) facility, which provides a convenient way to
translate a dictionary into an arbitrary binary representation.

thorpej | branches: 1.2.2;
Add kernel and user space parts of a protocol for sending property lists
to / from the kernel using ioctls.
|
| 1.1 |
| 27-Apr-2006 |
thorpej | Initial commit of proplib, a library for manipulating property lists and
converting to/from an XML external representation (based on Apple XML
property lists). Works in the kernel and user space.

Consider '\r' to be white space. Discussed with and also kept as local
change by freza. With this change, DOS style line endings work.
boolean_t -> bool
TRUE -> true
FALSE -> false
libprop is currently using a recursive parser. While this is fine for
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.
struct plistref does not reference other proplib data types, so split it
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@.
Attempt at fixing build failures after proplib was converted to bool:
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@).
Avoid using unbound amount of stack frames in prop_object_equal
by using a dynamic stack as well. Reorder arguments for the internalizer
as the iteration is always present and should go before possibly
NULL arguments.
