Hi John,
please pull to your wireless-dev tree from
git://git.kernel.org/pub/scm/linux/kernel/git/jbenc/dscape.git up
to obtain following patches. They were all posted to netdev previously and
are all discussed with Jouni (except 7th patch, but that is quite simple and
shouldn't cause any harm).
Also, the new rule of required kerneldoc documentation is hopefully
fulfilled - the only exception is ieee80211_hw structure, which is
well-commented but with comments inside. I think it will be best to convert
comments in ieee80211_hw by a separate patch.
Please note that these changes break d80211 drivers.
Jiri Benc:
d80211: symlinks to wiphy in sysfs
d80211: allow WDS remote to by set by WE
d80211: add IBSS and monitor interface types
d80211: non-shared interface types
d80211: remove local->bssid variable
d80211: rename IEEE80211_SUB_IF_TYPE_ constants
d80211: ask driver for allowed iface combinations
d80211: remove obsolete stuff
d80211: fix interface configuration
d80211: rename adm_status to radio_enabled
d80211: interface types changeable by SIOCSIWMODE
d80211: master interface auto up/down
d80211: set_multicast_list
d80211: fix handling of received frames
d80211: fix monitor interfaces
d80211: fix AP interfaces

MODULE_PARM macro was removed and this broke net/d80211 build. Fix
this by using module_param instead of MODULE_PARM.

This patch adds symlinks under /sys/net/*/wiphy pointing to
/sys/class/ieee80211/phyX.
This allows new interfaces to be added by writing a new name to e.g.
/sys/net/wlan0/wiphy/add_iface.

Setting of address of WDS remote peer wasn't possible by a WE call. Remote
WDS peer can be understood as a remote AP and SIOCSIWAP/SIOCGIWAP are unused
in WDS mode, so let's use them.

This patch removes "iwmode" variable (local->conf.mode) shared by all
interfaces. Instead, every interface has its own type (STA/IBSS/AP/WDS).
Please note, that
- Actual SIOCSIWMODE ioctl is disabled by this patch and is implemented by
one of subsequent patches.
- There is no way to ask the driver if given combination of interfaces is
possible. Again, it is implemented by one of subsequent patches.

As we're going to expose IEEE80211_SUB_IF_TYPE_* constants to drivers, the
prefix IEEE80211_SUB_IF_TYPE_ is no longer appropriate. The constants are
going to mean the type of 802.11 interface, not the type of sub-interface
structure (which is not visible to drivers at all).
This patch renames them to IEEE80211_IF_TYPE_*.

Not all combinations of interfaces (in fact, very few combination of
interfaces) are possible to be UP together. When an interface is going UP,
let's ask the driver if this is possible.
Please note that ieee80211_if_init_conf structure is not complete yet - new
fields will need to be added to allow drivers to decide.

Because any number of interfaces may be added, bss_devs and sta_devs arrays
cannot be fixed-size arrays. We can make them linked lists, but they are
needed for optimalization only (and even that is questionable with
subsequent patches). Let's remove them; we will probably want something
similar later to speed up packet receiving, but let's not bother ourselves
now.
Also, ieee80211_addr_inc is removed. Choosing of MAC address of a new STA
should be matter of userspace. It's responsibility of the stack not to allow
two STAs with the same MAC address to be up - this feature is introduced in
one of subsequent patches.

From: Jiri Benc @ 2006-04-21 20:11 UTC (permalink / raw)
To: netdev; +Cc: John W. Linville
This patch fixes some problems in interface configuration.
- Pass interface ID to add_interface and remove_interface callbacks. This ID
is used by a driver when calling ieee80211_beacon_get and
ieee80211_get_buffered_bc functions.
- New configuration callback, config_interface, is introduced.
- Allow BSSID to be set per-interface.

PRISM2_PARAM_ADM_STATUS is not much descriptive name. This patch renames it
to PRISM2_PARAM_RADIO_ENABLED, sets radio_enabled to 1 by default (this is
no problem as radio must not be enabled until at least one network interface
is running) and removes automatic setting of adm_status when interface is in
a STA mode.
Later, PRISM2_PARAM_RADIO_ENABLED value can be removed and radio_enabled set
by SIOCSIWTXPOW handler (ie. by iwconfig txpower off).

Allow type of interface to be set by SIOCSIWMODE. All of functions
responsible for adding/removing/initialization of interfaces were moved to
a new file ieee80211_iface.c. Function for removing interface was split into
two parts: one for deinitialization of the interface and one for
deallocation of the interface. That way, it is possible to change the type
of interface just by deinitializing and initializing it.
Also, remove set_mac_address callback to a driver, as it is not needed
anymore (drivers are notified about MAC addresses through add_interface
callback).
Please note, that although after this patch interfaces are fully independent
and driver can correctly control which combination is allowed, not all
multicast frames are received correctly by all respective interfaces. This
is addressed by subsequent patches.

There is no reason to put master interface to UP/DOWN state manually.
Calling of hw->open and hw->stop callbacks logically belongs to
ieee80211_master_open and ieee80211_master_stop functions, but then we need
to refuse putting master interface to UP state when there is no other
interface running, and similarly, to refuse putting master interface DOWN
when there are other interfaces running. Because the second is not possible,
hw->open and hw->stop need to be called from ieee80211_open/ieee80211_stop.

Add set_multicast_list callback. The version of set_multicast_list in
struct net_device cannot be used by a driver, because the driver is
interested in cumulative flags and cumulative multicast list from all
interfaces.

Make sure that every frame reaches every interface it belongs to.
Previously, some packet (most notably multicast ones) were not delivered to
all interface they should be delivered to. This also allows monitor
interfaces to work easily, even together with regular interfaces.
On a typical setup (i.e. one or two interfaces only) this patch shouldn't
have significant impact on performance. However, on a setup with great
number of interfaces, things will probably slow down. This is not a problem
with design of this patch - things can be relatively easily sped up later.
See related comment in 'd80211: remove obsolete stuff' patch.

This patch allows monitor interfaces to be set by SIOCSIWMODE and to receive
frames.
Also, "soft" and "hard" monitor modes are introduced.

actually means. I suppose it means that the device will receive control
frames too, but I don't know if that's right.

Some devices need to be switched to completely different mode to be able
to receive all frames (including control ones) or even load another
firmware. Such devices are not capable to transmit anything while in
monitor mode and their drivers won't set monitor_during_oper.
Another devices are capable to receive all frames while continuing their
normal operation. Driver will probably set monitor_during_oper in that
case.
"Hard" monitor mode means the card is operating in a true rfmon mode -
i.e. you get everything on the given channel. "Soft" monitor mode means
that you will get only frames the device is willing to give you at the
time - this probably means only frames belonging to your BSS in case of
fullmac cards.
So, you can always do
echo -n sta0 > /sys/class/ieee80211/wiphy0/add_iface
echo -n mon0 > /sys/class/ieee80211/wiphy0/add_iface
iwconfig sta0 mode managed
iwconfig mon0 mode monitor
ifconfig sta0 up
ifconfig mon0 up
and this will work - independently of the value of monitor_during_oper.
The difference is that in case of monitor_during_oper == 0, you won't
probably receive much more frames from mon0 than from sta0. But - you
will most likely receive beacons on mon0 and also monitoring headers
(prism2 headers presently).
When monitor_during_oper == 1, you are able to watch all traffic on the
current channel on mon0 without interrupting normal functionality.

Ok, thanks for clarifying; this description should be somewhere in the
comments or so IMHO.

This I don't understand, doesn't the UI kind of suck as opposed to just
putting the sta0 device into promisc mode?

In promisc mode, you receive only packets destined to your BSS,
regardless of their source or destination address (so it's similar to
the way promisc works with Ethernet). On monitor interface, you receive
all packets regardless of BSSID.

Yes, but didn't you just say that when monitor_during_oper == 0 then
it's equivalent to promisc mode?

Not necessary. It was just an example of the worst case. In typical
case, you will receive something more - probably all data and management
frames but no control frames.

Ah right, yeah makes sense then I guess. So monitor is a way of telling
the driver "give me everything that you can" :)

Hacky or not, I'm applying this patch to keep the bcm43xx driver
from breaking. I don't suppose you have a patch for the rt2x00 driver?

Hi,
I had promised to create this patch before, but due to shortage of time
hadn't managed to do so. At the moment a compatibility fix for the updates
is already present in our CVS tree.
I am already working on a patch series to send for wireless-dev to bring rt2x00
up to date. The change for compatibility for the stack is update is also amongst the
patches. I am still working on the final patches for the series, but will be able to
send all (+/- 30 patches) tomorow.
After that I hope to send new patches for rt2x00 on a more regular basis,
to prevent large patch series like this one to be send in a single day.

That's perfectly fine.
The correct patch needs a little bit of rewriting in the "mode" code.
I will do that after I finished the 4318 fixes (should take quite
some time).

The patch for bcm43xx was really just quick fix, only partially
tested...
