* ppp: allow disabling multilink protocol ID compressionstephen hemminger2010-12-281-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | Linux would not connect to other router running old version Cisco IOS (12.0). This is most likely a bug in that version of IOS, since it is fixed in later versions. As a workaround this patch allows a module parameter to be set to disable compressing the protocol ID. See: https://bugzilla.vyatta.com/show_bug.cgi?id=3979 RFC 1990 allows an implementation to formulate MP fragments as if protocol compression had been negotiated. This allows us to always send compressed protocol IDs. But some implementations don't accept MP fragments with compressed protocol IDs. This parameter allows us to interoperate with them. The default value of the configurable parameter is the same as the current behavior: protocol compression is enabled. If protocol compression is disabled we will not send compressed protocol IDs. This is based on an earlier patch by Bob Gilligan (using a sysctl). Module parameter is writable to allow for enabling even if ppp is already loaded for other uses.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | bond_na_send() attempts to insert a VLAN tag in between building and sending packets of the respective formats. If the slave does not implement hardware VLAN tag insertion then vlan_put_tag() will mangle the network-layer header because the Ethernet header is not present at this point (unlike in bond_arp_send()). Fix this by adding the tag out-of-line and relying on dev_hard_start_xmit() to insert it inline if necessary.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A bond may have a mixture of slave devices with and without hardware VLAN tag insertion capability. Therefore it always claims this capability and performs software VLAN tag insertion if the slave does not. Since commit 7b9c60903714bf0a19d746b228864bad3497284e, this has also been done by dev_hard_start_xmit(). The result is that VLAN- tagged skbs are now double-tagged when transmitted through slave devices without hardware VLAN tag insertion! Remove the now-redundant logic from bond_dev_queue_xmit().

It also prevents wpa_supplicant from getting scan results, as wpa_supplicant disables countermeasures on startup - preventing the hardware from scanning. wpa_supplicant works with ap_mode=2 despite this bug because the commit handler re-enables the port. The log tends to look like: State: DISCONNECTED -> SCANNING Starting AP scan for wildcard SSID Scan requested (ret=0) - scan timeout 5 seconds EAPOL: disable timer tick EAPOL: Supplicant port status: Unauthorized Scan timeout - try to get results Failed to get scan results Failed to get scan results - try scanning again Setting scan request: 1 sec 0 usec Starting AP scan for wildcard SSID Scan requested (ret=-1) - scan timeout 5 seconds Failed to initiate AP scan.

In these situations, you are usually trying to connect to a new AP, so keeping TKIP countermeasures active is confusing. This is already how the driver behaves (inadvertently). However, querying SIOCGIWAUTH may tell userspace that countermeasures are active when they aren't. Clear the setting so that the reporting matches what the driver has done..

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The interrupt handler takes a lock - but since commit bcad6e80f3f this lock goes through an indirection specified in the hermes_t structure. We must therefore initialise the structure before setting up the interrupt handler.

| | * ath9k: fix beacon resource related race conditionRajkumar Manoharan2010-12-071-14/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The beacon tasklet is accesssing the bslot info for beacon generation. Meanwhile the same slot can be freed on interface deletion. Current the remove_interface disables the beacon alert after freeing the slot. This may leads to null pointer access. This patch disables SWBA and kills the beacon tasklet to prevent access to the slot to be freed. After releasing the slot, swba will be enabled again upon the availablity of beaconing interfaces.

Due to this, MIC failure events for broadcast frames are not sent to supplicant resulted in AP disconnecting the STA. Able to pass Wifi Test case 5.2.18 with this fix.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When ath_drain_all_txq fails to stop DMA, it issues a hw reset. This reset happens at a very problematic point in time, when the hardware rx path has not been stopped yet. This could lead to memory corruption, hardware hangs or other issues. To fix these issues, simply remove the reset entirely and check the tx DMA stop status to prevent problems with fast channel changes.

The resulting value is assigned in an u16 which overflows and makes the card work at full power. Cc: stable@kernel.org Signed-off-by: Matteo Croce <matteo@openwrt.org> Signed-off-by: John W.
