by Geoff C. Wing and others.  ok'ed by Jason Thorpe.

dyoung 848e7ffe8c In prop_data_create_data(blob, len), if len == 0, allocate no memory 
for blob, and leave pd_mutable set to NULL.  In this way, avoid
tripping over the assertion in prop_data_data_nocopy().

tron e70ab693a2 Change the argument of _PROP_RWLOCK_TRYRDLOCK() to the lock member and not 
its address to be consistent with all the other macros.
 2008-05-07 10:16:41 +00:00
tron 2916b940f8 Replace _prop_rwlock_tryrdlock() by a macro _PROP_RWLOCK_TRYRDLOCK(). 
This avoids build failures in stand alone binaries (e.g. bootloaders)
where there is no "pa_rwlock" member in the "_prop_array" structure.

simonb 4ec02db9e9 Fix a "#define<tab><tab>" that crept in to previous. 2008-05-07 05:40:01 +00:00
xtraeme 35fe7cdcf1 prop_object_iterator_next() and prop_object_iterator_reset() were 
acquiring the rwlock recursively in some paths.

Introduce _prop_rwlock_tryrdlock() and use it in these functions, so
that the rwlock is *always* acquired once, while here add some
_PROP_RWLOCK_OWNED asserts to verify.

This definitely fixes the "locking against myself" panics.

xtraeme d69a8a8939 Xref prop_dictionary_util(3). 2008-05-06 17:23:38 +00:00
xtraeme 771a05b730 Do not acquire the rwlock recursively in prop_{array,dictionary}_iterator_reset() 
when prop_{array,dictionary}_copyout_ioctl() is called.

Introduce _PROP_RWLOCK_OWNED() which is a KASSERT(rw_lock_held(lock))
and use it in those two functions, also acquire the rwlock in other
places where it is required now.

This fixes a LOCKDEBUG panic "locking against myself", as reported by
Geoff C. Wing in current-users@.

garbled 2ba84f0f9e Add tuned powerpc assembler written by IBM and released under a 3-clause 
BSD Lisc as part of the perflib project.
http://sourceforge.net/projects/ppcperflib/

Tested the new functions with microbenchmarks on a number of different
CPU types, and  found that most cpus either benefited greatly, or were
unaffected.  Primarily G4 CPU's were unaffected, and all others showed
speedups.  My 7044 (POWER3) went from a 70.6 to a 73.2 (thats good) in
bytebench with a complete release built with these.  Also passed
regression tests.

some #ifs from the i386 port.

Also, align sun2 with the other m68k ports as to whether they
define __bswap{16,32} or bswap{16,32} in their C library (all
now define the __ variants).

This should make the m68k ports build sys/rump again, except
for sun2 which hits another problem later on.

pavel c0f560c80e struct plistref does not reference other proplib data types, so split it

by dogcow@.

joerg e835604c26 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.

joerg 17c77a58f0 Fix SIGBUS issues on strict alignment issues. Use le32dec in RMD160 
as the data pointer to RMD160_Update doesn't have to be aligned.
In SHA256_Update and SHA512_Update, only operate directly on the passed
in data if no left-over in the context exists and the data is correctly
aligned. The problem was exposed by the audit-packages rewrite in C
and reported for the libnbcompat version in PR pkg/36662.

 2006-11-28 18:36:26 +00:00
cube 00fbe2b725 In _prop_object_copyout_ioctl, uaddr was not initialised, although it is 
used by uvm_mmap() as a hint for the virtual address to map memory to.  As
a consequence, it tended to fail a lot on some architectures.

We cannot use 0, so instead use the value that would have been used if we
were calling mmap(2) with 0 as the first argument.

thorpej 26d4f90430 - Add prop_dictionary_all_keys(). Takes a snapshot of a dictionary's 
keys and returns them in an array.  This effectively allows a caller
  to mutate a dictionary while iterating over it (really, you iterate
  over the array of keys instead of the dictionary itself).

  circumstances, anyway) to get/set values in a dictionary.

thorpej 6cf1ffe998 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.

only ever allocating one object for any given number (we can do this
because numbers are immutable).  This results in significant run-time
memory savings.

thorpej d21620b264 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.

christos 8ca2029daf always compile in the userland portion. XXX: We might want to change this 
to __no_instrument_function__ like the kernel does.

he 2f2fd2a0ad Add the m68010 versions of the integer multiply divide, modulo, 
and multiply functions from the old libkern.  The m68010 versions
are only compiled when __mc68010__ is defined, presently that's
only done when building for sun2.

tsutsui d5f01723d6 Don't redefine _LOCORE if it's already defined. 
Some Makefiles for standalone programs already have it.

XXX Old src/sys/lib/libkern/arch/mips/memcpy.S had some #ifdef MIPS3_5900
XXX which added some extra nops, but this new common bcopy.S doesn't.
