Michael Buesch [Thu, 19 Mar 2009 18:27:21 +0000]
b43: Mask PHY TX error interrupt, if not debugging

This masks the PHY TX error interrupt, if debugging is disabled.

Currently we have a bug somewhere which triggers this interrupt once
in a while. (Depends on the network noise/quality). While this is nonfatal,
it scares the hell out of users and we frequently receive bugreports
that incorrectly identify this error message as the reason.

There's another problem with this. The PHY TX error interrupt is protected
with a watchdog that will restart the device if it keeps triggering very often.
This is used to fix interrupt storms from completely broken devices.

However, this watchdog might trigger in completely normal operation.
If the TX capacity of the card is saturated, the likeliness of the watchdog
triggering increases, as more TX errors occur. The current threshold
for the watchdog is 1000 errors in 15 seconds.

This patch adds a workaround for the issue by just enabling the interrupt
if debugging is disabled (by Kconfig or by modparam).

This has the downside that real fatal PHY TX errors are not caught anymore.
But this is nonfatal due to the following reasons:
* If the card is not able to transmit anymore, MLME will notice anyway.
* I did _never_ see a real fatal PHY TX error in a mainline b43 driver.
* It does _not_ result in interrupt storms or something like that.
  It will simply result in a stalled card. It can be debugged by enabling
  the debugging module parameter.

Jouni Malinen [Thu, 19 Mar 2009 11:39:22 +0000]
nl80211: Add MLME primitives to support external SME

This patch adds new nl80211 commands to allow user space to request
authentication and association (and also deauthentication and
disassociation). The commands are structured to allow separate
authentication and association steps, i.e., the interface between
kernel and user space is similar to the MLME SAP interface in IEEE
802.11 standard and an user space application takes the role of the
SME.

The patch introduces MLME-AUTHENTICATE.request,
MLME-{,RE}ASSOCIATE.request, MLME-DEAUTHENTICATE.request, and
MLME-DISASSOCIATE.request primitives. The authentication and
association commands request the actual operations in two steps
(assuming the driver supports this; if not, separate authentication
step is skipped; this could end up being a separate "connect"
command).

The initial implementation for mac80211 uses the current
net/mac80211/mlme.c for actual sending and processing of management
frames and the new nl80211 commands will just stop the current state
machine from moving automatically from authentication to association.
Future cleanup may move more of the MLME operations into cfg80211.

The goal of this design is to provide more control of authentication and
association process to user space without having to move the full MLME
implementation. This should be enough to allow IEEE 802.11r FT protocol
and 802.11s SAE authentication to be implemented. Obviously, this will
also bring the extra benefit of not having to use WEXT for association
requests with mac80211. An example implementation of a user space SME
using the new nl80211 commands is available for wpa_supplicant.

This patch is enough to get IEEE 802.11r FT protocol working with
over-the-air mechanism (over-the-DS will need additional MLME
primitives for handling the FT Action frames).

station and IBSS modes (i.e., MLME SAP interface primitives
MLME-AUTHENTICATE.confirm, MLME-ASSOCIATE.confirm,
MLME-REASSOCIATE.confirm, MLME-DEAUTHENTICATE.indicate, and

Kalle Valo [Wed, 18 Mar 2009 12:06:44 +0000]
mac80211: don't drop nullfunc frames during software scan

ieee80211_tx_h_check_assoc() was dropping everything else than probe
requests during software scan. So the nullfunc frame with the power save
bit was dropped and AP never received it. This meant that AP never
buffered any frames for the station during software scan.

Fix this by allowing to transmit both probe request and nullfunc frames
during software scan. Tested with stlc45xx.

mac80211: Tear down aggregation sessions for suspend/resume

When the driver has been notified with a STA_REMOVE, it tears down
the internal ADDBA state. On resume, trying to initiate aggregation would
fail because mac80211 has not cleared the operational state for that <TID,STA>.
This can be fixed by tearing down the existing sessions on a suspend.

Also, the driver can initiate a new BA session when suspend is in progress.
This is fixed by marking the station as being in suspend state and
denying ADDBA requests for such STAs.

mac80211: reduce max number of queues

No hw/driver actually supports more than four queues right now,
and we allocate a number of things per queue which means we
waste a bit of memory. Reduce the maximum number to four to
accurately reflect what we do (and need for QoS). Even if we
had hardware supporting more queues we couldn't take advantage
of that right now anyway.

cfg80211/nl80211: remove usage of CONFIG_NL80211

The scan capability added to cfg80211/nl80211 introduced a
dependency on nl80211 by cfg80211. We can thus no longer have
just cfg80211 without nl80211. Specifically, cfg80211_scan_done()
calls nl80211_send_scan_aborted() or nl80211_send_scan_done().

Now we remove the option for user to select nl80211. It will always
be compiled if user selects cfg80211.

11 years agoucc_geth: Fix three oopses in PHY {de,}initialization code
Anton Vorontsov [Fri, 27 Mar 2009 23:00:03 +0000]
ucc_geth: Fix three oopses in PHY {de,}initialization code

When there are no free snums, UCC ethernet should gracefully fail, but
currently it oopses this way:

  # ifconfig eth0 up
  fill_init_enet_entries: Can not get SNUM.
  ucc_geth_startup: Can not fill p_init_enet_param_shadow.
  eth0: Cannot configure net device, aborting.
  Unable to handle kernel paging request for data at address 0x00000190
  Faulting instruction address: 0xc0294c88
  Oops: Kernel access of bad area, sig: 11 [#1]
  [...]
  NIP [c0294c88] mutex_lock+0x0/0x1c
  LR [c01b6be8] phy_stop+0x20/0x70
  Call Trace:
  [efb25da0] [efb2eb60] 0xefb2eb60 (unreliable)
  [efb25db0] [c01b2058] ucc_geth_stop+0x2c/0x8c
  [efb25dd0] [c01b4194] ucc_geth_open+0x48/0x27c
  [efb25df0] [c020eec0] dev_open+0xc0/0x118
  [...]

This is because the ucc_geth_stop() routine assumes that ugeth->phydev
is always initialized by the ucc_geth_open(), while it is not in case
of errors.

If we add a check to the ucc_geth_stop(), then another oops pops up:

  Unable to handle kernel paging request for data at address 0x00000004
  Faulting instruction address: 0xc01b46a4
  Oops: Kernel access of bad area, sig: 11 [#1]

  [ef83bff0] [c000f464] kernel_thread+0x4c/0x68
  [...]

That one happens because ucc_geth_stop() does not call phy_disconnect()
and so phylib state machine is running without any idea that a MAC has
just died.

Also, when device tree specifies fixed-link, and CONFIG_FIXED_PHY
is disabled, we'll get this oops:

  0:01 not found
  eth2: Could not attach to PHY
  eth2: Cannot initialize PHY, aborting.
  Unable to handle kernel paging request for data at address 0x00000190

  [ef82bff0] [c000f464] kernel_thread+0x4c/0x68
  [...]

And again, ucc_geth_stop() assumes that ugeth->phydev is there, while
it isn't.

This patch fixes all three oopses simply by rearranging some code:

- In ucc_geth_open(): move init_phy() call to the beginning, so
  that we only call ucc_geth_stop() with a PHY attached;
- Move phy_disconnect() call from ucc_geth_close() to
  ucc_geth_stop(), so that we'll always disconnect the PHY.

11 years agonet: Add missing include into include/linux/netdevice.h

net: Add missing include into include/linux/netdevice.h

The inline function skb_gro_mac_header defined in include/linux/netdevice.h
makes use of page_address(). Depending on configuration options, the latter
is either defined as a macro or is declared as a function in another header
file, namely include/linux/mm.h. However, include/linux/netdevice.h does not
include include/linux/mm.h.

On MIPS, this has produced the following build error:
