2010-03-16net-2.6 [Bug-Fix][dccp]: fix oops caused after failed initialisationGerrit Renker3-15/+17
dccp: fix panic caused by failed initialisation This fixes a kernel panic reported thanks to Andre Noll: if DCCP is compiled into the kernel and any out of the initialisation steps in net/dccp/proto.c:dccp_init() fail, a subsequent attempt to create a SOCK_DCCP socket will panic, since inet{,6}_create() are not prevented from creating DCCP sockets. This patch fixes the problem by propagating a failure in dccp_init() to dccp_v{4,6}_init_net(), and from there to dccp_v{4,6}_init(), so that the DCCP protocol is not made available if its initialisation fails.

Registering/unregistering the Gigaset CAPI driver when a device is connected/disconnected causes an Oops when disconnecting two Gigaset devices in a row, because the same capi_driver structure gets unregistered twice.

2010-03-16i4l: silence compiler warnings for array access in Eicon DIVA ISDN driverIan Munsie1-8/+7
When compiling this driver, the compiler throws the following warnings: drivers/isdn/hardware/eicon/message.c:8426: warning: array subscript is above array bounds drivers/isdn/hardware/eicon/message.c:8427: warning: array subscript is above array bounds drivers/isdn/hardware/eicon/message.c:8434: warning: array subscript is above array bounds drivers/isdn/hardware/eicon/message.c:8435: warning: array subscript is above array bounds drivers/isdn/hardware/eicon/message.c:8436: warning: array subscript is above array bounds drivers/isdn/hardware/eicon/message.c:8447: warning: array subscript is above array bounds This arises from the particular semantics the driver is using to write to the nlc array (static byte[256]). The array has a length in byte 0 followed by a T30_INFO struct starting at byte 1. The T30_INFO struct has a number of variable length strings after the station_id entry, which cannot be explicitly defined in the struct and the driver accesses them with an array index to station_id beyond the length of station_id. This patch merely changes the semantics that the driver uses to access the entries after the station_id entry to use the original 256 byte nlc array taking the offset and length of the station_id entry to calculate where to write in the array, thereby silencing the warning.

2010-03-12ipconfig: Handle devices which take some time to come up.David S. Miller1-10/+47
Some network devices, particularly USB ones, take several seconds to fully init and appear in the device list. If the user turned ipconfig on, they are using it for NFS root or some other early booting purpose. So it makes no sense to just flat out fail immediately if the device isn't found. It also doesn't make sense to just jack up the initial wait to something crazy like 10 seconds. Instead, poll immediately, and then periodically once a second, waiting for a usable device to appear.

2010-03-11ath5k: fix I/Q calibration (for real)Bruno Randolf2-18/+20
I/Q calibration was completely broken, resulting in a high number of CRC errors on received packets. before i could see around 10% to 20% CRC errors, with this patch they are between 0% and 3%. 1.) the removal of the mask in commit "ath5k: Fix I/Q calibration (f1cf2dbd0f798b71b1590e7aca6647f2caef1649)" resulted in no mask beeing used when writing the I/Q values into the register. additional errors in the calculation of the values (see 2.) resulted too high numbers, exceeding the masks, so wrong values like 0xfffffffe were written. to be safe we should always use the bitmask when writing parts of a register. 2.) using a (s32) cast for q_coff is a wrong conversion to signed, since we convert to a signed value later by substracting 128. this resulted in too low numbers for Q many times, which were limited to -16 by the boundary check later on. 3.) checked everything against the HAL sources and took over comments and minor optimizations from there. 4.) we can't use ENABLE_BITS when we want to write a number (the number can contain zeros). also always write the correction values first and set ENABLE bit last, like the HAL does.

AR5K_STA_ID1_DEFAULT_ANTENNA). also i would like to note that antenna diversity does not always work correctly on 5414 (at least) when only one antenna is connected: for example all frames might be received on antenna A but still the HW tries to send on antenna B some times, causing packet loss. this is both verified with the antenna statistics output of the previous patch and a spectrum analyzer.

2010-03-10qeth: no recovery after layer mismatch (z/VM NICs)Ursula Braun3-21/+14
Depending on their definition in z/VM, virtual devices for z/VM VSWITCH or GuestLAN must be configured either in layer2 or in layer3 mode. If qeth detects a layer mismatch, device activation fails. Trying to recover from this error cannot help; thus scheduling a recovery should be avoided. In addition, since recovery is forbidden during online setting of a qeth device, existence of its network device is guaranteed for all dev_close() calls in qeth. The corresponding checks can be removed. Signed-off-by: Ursula Braun <ursula.braun@de.ibm.com> Signed-off-by: Frank Blaschka <frank.blaschka@de.ibm.com> Signed-off-by: David S.

2010-03-10qeth: set promisc off after trace disabling failureUrsula Braun1-26/+30
If HiperSockets Network Traffic Analyzer is switched off, but trace disabling fails somehow, the qeth driver does not switch off its promisc mode status. A following sniffer reactivation fails, since qeth does not see a need to reenable tracing. At the same time the code analyzing results of trace commands is restructured.

2010-03-10qeth: l3 send dhcp in non pass thru modeFrank Blaschka2-7/+6
dhcp frames are valid IPv4 packets so there is no need to send them in pass thru mode. This allows dhcp packets to pass HiperSockets. Also the dhcp release frame is send out correctly with this patch.
