- Socket layer becomes MP safe.
- Unix protocols become MP safe.
- Allows protocol processing interrupts to safely block on locks.
- Fixes a number of race conditions.
With much feedback from matt@ and plunky@.
btuartd(8) should be named btattach(8) for consistency
with other parts of NetBSD
make btattach(8) a single-use tool for less complexity
device specicific initialisation (from btuart(4)) is carried
out prior to activating the line discipline (in btattach(8)),
which simplifies the API somewhat and means that the user
tool and the kernel do not need to be kept in sync.
btuart(4) driver is much reduced; naming is made consistent
and all tsleep() and delay() are removed to userland
As all identifying information is stored in the device
properties, this removes the need for child devices to
have a reserved area (struct btdev) in the softc, and
bthub(4) does no longer need to have a softc at all.
to remove the frobbing that drivers must do in the hci_unit structure.
- driver provides a static const interface descriptor
- hci_unit is allocated by hci_attach() rather than part of softc
- statistics are compiled by driver and provided on request
- driver provides output methods and is responsible for output queue
- stack provides input methods and is responsible for input queue
- mutex is used to arbitrate device queue access
make bluetooth stack keep device_t instead of softc pointer as
device is not necessarily part of softc, and pass device_t to
driver callbacks. hci_devname is no longer required.
softc no longer contains 'struct device' by default
use 'device_t' instead of 'struct device *'
use device_xxx() accessor functions
remove casting of 'xxx_softc *' & 'struct device *'
use aprint_xxx_dev() routines
+ Initialize m_pkthdr.len, and increment if not escape charactor.
+ Call bcsp_start() if there is no transmitted packet.
+ Call m_adj() after debug print.
+ Reset the values of the Sequencing layer if link reset it.
the Linux (BlueZ) API.
- L2CAP or RFCOMM connections can require the baseband radio link
mode be any of:
authenticated (devices are paired)
encrypted (implies authentication)
secured (encryption, plus generate new link key)
- for sockets, the mode is set using setsockopt(2) and the socket
connection will be aborted if the mode change fails.
- mode settings will be applied during connection establishment, and
for safety, we enter a wait state and will only proceed when the mode
settings are successfuly set.
- It is possible to change the mode on already open connections, but
not possible to guarantee that data already queued (from either end)
will not be delivered. (this is a feature, not a bug)
- bthidev(4) and rfcomm_sppd(1) support "auth", "encrypt" and
"secure" options
- btdevctl(8) by default enables "auth" for HIDs, and "encrypt" for
keyboards (which are required to support it)
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.
when the bluetooth code is not expecting it to be. During a disconnect, we can
detach the channel that is being disconnected, but its not really safe to detach
any others.
- sco_getopt(..., SO_SCO_MTU, ...) expects the address of a uint16_t,
not an int. So change sc_mtu's type to uint16_t.
- Try a little harder to ensure btsco_round_blocksize() does not
return zero. Prevents a subsequent panic in audio_init_ringbuffer().
