10 years agogso: Fix support for linear packets

gso: Fix support for linear packets

When GRO/frag_list support was added to GSO, I made an error
which broke the support for segmenting linear GSO packets (GSO
packets are normally non-linear in the payload).

These days most of these packets are constructed by the tun
driver, which prefers to allocate linear memory if possible.
This is fixed in the latest kernel, but for 2.6.29 and earlier
it is still the norm.

Therefore this bug causes failures with GSO when used with tun
in 2.6.29.

mac80211/iwlwifi: move virtual A-MDPU queue bookkeeping to iwlwifi

This patch removes all the virtual A-MPDU-queue bookkeeping from
mac80211. Curiously, iwlwifi already does its own bookkeeping, so
it doesn't require much changes except where it needs to handle
starting and stopping the queues in mac80211.

To handle the queue stop/wake properly, we rewrite the software
queue number for aggregation frames and internally to iwlwifi keep
track of the queues that map into the same AC queue, and only talk
to mac80211 about the AC queue. The implementation requires calling
two new functions, iwl_stop_queue and iwl_wake_queue instead of the
mac80211 counterparts.

mac80211: fix aggregation to not require queue stop

Instead of stopping the entire AC queue when enabling aggregation
(which was only done for hardware with aggregation queues) buffer
the packets for each station, and release them to the pending skb
queue once aggregation is turned on successfully.

We get a little more code, but it becomes conceptually simpler and
we can remove the entire virtual queue mechanism from mac80211 in
a follow-up patch.

This changes how mac80211 behaves towards drivers that support
aggregation but have no hardware queues -- those drivers will now
not be handed packets while the aggregation session is being
established, but only after it has been fully established.

When TX aggregation becomes operational, we do a number of steps:

 2) wake the virtual queue
 3) notify the driver

Unfortunately, 1) and 3) are only done if the driver is first to

remote station replies before the driver! Thus, unify the code for
this and call the new function ieee80211_agg_tx_operational in both
places where TX aggregation can become operational.

Additionally, rename the driver notification from

10 years agob43: Mask PHY TX error interrupt, if not debugging
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

nl80211, on the other hand, has the reverse lock dependency:

Sujith [Tue, 17 Mar 2009 03:20:06 +0000]
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.
