b105a06908 Update beacon handling to sync w/ vap code base:
o add driver callback to handle notification of beacon changes;
  this is required for devices that manage beacon frames themselves
  (devices must override the default handler which does nothing)
o move beacon update-related flags from ieee80211com to the beacon
  offsets storage (or handle however a driver wants)
o expand beacon offsets structure with members needed for 11h/dfs
  and appie's
o change calling convention for ieee80211_beacon_alloc and
  ieee80211_beacon_update
o add overlapping bss support for 11g; requires driver to pass
  beacon frames from overlapping bss up to net80211 which is not
  presently done by any driver
o move HT beacon contents update to a routine in the HT code area

2b9411e29f Add missing bits that made bg scanning lame:
o update ic_lastdata to reflect time of last outbound frame
o outbound traffic must preempt/cancel bg scanning to avoid delays

This stuff was somehow missed in the initial import.

bbc84740c1 Latest round of usb cleanups:
o Consistently use device_foo_t and bus_foo_t for functions implementing
  device_foo and bus_foo respectively.  Adjust those routines that were wrong
  (we should do this throughout the tree).
o make all the modules depend on usb.  Otherwise these modules won't
  load.
o ucycom doesn't need usb_port.h
o Minor unifdefing
o uhub, umass, ums, urio, uscanner conversion complete.
o ukbd: Remove the NO_SET_PROTO quirk (fixes a PR 77940).  NetBSD removed
  their check and setting the proto a long time ago.
o umodem panic fixed.  UQ_ASSUME_CM_OVER_DATA quirk removed because I've never
  seen a umodem that needed this rejection for proection (this gets rid of
  ~20% of the quirks).

68e8e04e93 Update 802.11 wireless support:
o major overhaul of the way channels are handled: channels are now
  fully enumerated and uniquely identify the operating characteristics;
  these changes are visible to user applications which require changes
o make scanning support independent of the state machine to enable
  background scanning and roaming
o move scanning support into loadable modules based on the operating
  mode to enable different policies and reduce the memory footprint
  on systems w/ constrained resources
o add background scanning in station mode (no support for adhoc/ibss
  mode yet)
o significantly speedup sta mode scanning with a variety of techniques
o add roaming support when background scanning is supported; for now
  we use a simple algorithm to trigger a roam: we threshold the rssi
  and tx rate, if either drops too low we try to roam to a new ap
o add tx fragmentation support
o add first cut at 802.11n support: this code works with forthcoming
  drivers but is incomplete; it's included now to establish a baseline
  for other drivers to be developed and for user applications
o adjust max_linkhdr et. al. to reflect 802.11 requirements; this eliminates
  prepending mbufs for traffic generated locally
o add support for Atheros protocol extensions; mainly the fast frames
  encapsulation (note this can be used with any card that can tx+rx
  large frames correctly)
o add sta support for ap's that beacon both WPA1+2 support
o change all data types from bsd-style to posix-style
o propagate noise floor data from drivers to net80211 and on to user apps
o correct various issues in the sta mode state machine related to handling
  authentication and association failures
o enable the addition of sta mode power save support for drivers that need
  net80211 support (not in this commit)
o remove old WI compatibility ioctls (wicontrol is officially dead)
o change the data structures returned for get sta info and get scan
  results so future additions will not break user apps
o fixed tx rate is now maintained internally as an ieee rate and not an
  index into the rate set; this needs to be extended to deal with
  multi-mode operation
o add extended channel specifications to radiotap to enable 11n sniffing

Drivers:
o ath: add support for bg scanning, tx fragmentation, fast frames,
       dynamic turbo (lightly tested), 11n (sniffing only and needs
       new hal)
o awi: compile tested only
o ndis: lightly tested
o ipw: lightly tested
o iwi: add support for bg scanning (well tested but may have some
       rough edges)
o ral, ural, rum: add suppoort for bg scanning, calibrate rssi data
o wi: lightly tested

This work is based on contributions by Atheros, kmacy, sephe, thompsa,
mlaier, kevlo, and others.  Much of the scanning work was supported by
Atheros.  The 11n work was supported by Marvell.

9145721957 Use a different task queue for host controller and peripheral driver
tasks. Since the host controllers rely on tasks to process transfer
timeouts, if a synchronous transfer from a driver was invoked from
a task and timed out, it would never complete because the single
task thread was stuck performing the synchronous transfer so couldn't
process the timeout.

This affected the axe, udav and ural drivers.

ff046a6c6b add missed calls to bpf_peers_present 2006-06-02 23:14:40 +00:00
Christian S.J. Peron
16d878cc99 Fix the following bpf(4) race condition which can result in a panic:
(1) bpf peer attaches to interface netif0
	(2) Packet is received by netif0
	(3) ifp->if_bpf pointer is checked and handed off to bpf
	(4) bpf peer detaches from netif0 resulting in ifp->if_bpf being
	    initialized to NULL.
	(5) ifp->if_bpf is dereferenced by bpf machinery
	(6) Kaboom

This race condition likely explains the various different kernel panics
reported around sending SIGINT to tcpdump or dhclient processes. But really
this race can result in kernel panics anywhere you have frequent bpf attach
and detach operations with high packet per second load.

Summary of changes:

- Remove the bpf interface's "driverp" member
- When we attach bpf interfaces, we now set the ifp->if_bpf member to the
  bpf interface structure. Once this is done, ifp->if_bpf should never be
  NULL. [1]
- Introduce bpf_peers_present function, an inline operation which will do
  a lockless read bpf peer list associated with the interface. It should
  be noted that the bpf code will pickup the bpf_interface lock before adding
  or removing bpf peers. This should serialize the access to the bpf descriptor
  list, removing the race.
- Expose the bpf_if structure in bpf.h so that the bpf_peers_present function
  can use it. This also removes the struct bpf_if; hack that was there.
- Adjust all consumers of the raw if_bpf structure to use bpf_peers_present

Now what happens is:

	(1) Packet is received by netif0
	(2) Check to see if bpf descriptor list is empty
	(3) Pickup the bpf interface lock
	(4) Hand packet off to process

From the attach/detach side:

	(1) Pickup the bpf interface lock
	(2) Add/remove from bpf descriptor list

Now that we are storing the bpf interface structure with the ifnet, there is
is no need to walk the bpf interface list to locate the correct bpf interface.
We now simply look up the interface, and initialize the pointer. This has a
nice side effect of changing a bpf interface attach operation from O(N) (where
N is the number of bpf interfaces), to O(1).

[1] From now on, we can no longer check ifp->if_bpf to tell us whether or
    not we have any bpf peers that might be interested in receiving packets.
