| * | | | be2net: Fix to fail probe if MSI-X enable fails for a VFSomnath Kotur2013-05-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As per SPEC, INTx mode is not supported on VFs. So if enable_msix fails, then just fail probe. Also bail out of be_open if irq_register fails. Signed-off-by: Somnath Kotur <somnath.kotur@emulex.com> Signed-off-by: David S. Miller <davem@davemloft.net>
| * | | | be2net: avoid napi_disable() when it has not been enabledSomnath Kotur2013-05-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When RQ creation fails in be_open(), driver jumps to be_close() where napi_disable() is done without a prior napi_enable(); leading to a hang. This change is needed as there is no way to see if napi is enable/disabled.

While the driver is quite simple, it caused discussion if we need additional arbitration on top of the one specified in the I2C standard. Conclusion is that I accept a few generic mechanisms, but not very specific ones. - the core lost the detach_adapter() call. It has no users anymore and was in the way for other cleanups. attach_adapter() is sadly still there since there are users waiting to be converted. - the core gained a bus recovery infrastructure. I2C defines a way to recover if the data line is stalled. This mechanism is now in the core and drivers can now pass some data to make use of it. - bigger driver cleanups for designware, s3c2410 - removing superfluous refcounting from drivers - removing Ben Dooks as second maintainer due to inactivity.

| * | | | i2c: Ignore return value of i2c_del_adapter()Lars-Peter Clausen2013-04-02

So all checks testing whether it will be non zero will always evaluate to false and the conditional code is dead code. This patch updates all callers of i2c_del_mux_adapter() to ignore the return value and assume that it will always succeed (which it will). In a subsequent patch the return type of i2c_del_adapter() will be made void.

Due to an erroneous initialization of resources, some of the bnx2x structs which are required for interrupt handling are initialized only after an interface's interrupt is requested from the OS. As a result, once such a spurious interrupt occurs, it will cause a NULL pointer dereference - the driver will access those structs in its interrupt handling routine. This patch change the interrupt request scheme so that bnx2x would only request interrupts from the kernel after it has finished initializing all the inner structs required for interrupt handling.

Longer responses are truncated, and we may read off the end of the buffer when copying out subtypes for additional partitions. In particular, this can result in the MTD partition for an FPGA bitfile being named e.g. 'eth5 sfc_fpga:00' when it should be 'eth5 sfc_fpga:01'. This means the firmware update tool (sfupdate) can't tell which bitfile should be written to the partition. Correct the response buffer size.

There are 2 patches in this series which could be applied to net, but since Linus is so very close to releasing 3.9, I do not think it prudent to try and push these into net at this time. I have CC'd stable on these patches so that they can queue them up as soon as 3.9 gets released. The 2 patches are: e1000e: fix numeric overflow in phc settime method ixgbe: fix EICR write in ixgbe_msix_other Richard provides a fix for e1000e by using a helper function from time.h to resolve a unintended overflow in the PTP settime function. Bruce provides a fix to wait for NAPI to be done with the current context after disabling interrupts and then disable NAPI when the interface is going down. This fixes a possible "unable to handle kernel paging request" panic in net-next. Andi Kleen provides a patch for igb to use mdelay instead of udelay when we needed 100000us. Jacob provides a fix for ixgbe to simply mask the lower 16bits off so that ixgbe_msix_other does not write them in the EICR, which causes them to remain high and be properly handled by the clean_rings interrupt routine as normal. Emil cleans up the logic in ixgbe_setup_loopback_test() to only access registers applicable to the MAC type. In addition, removes majority of the AUTOC register reads by using a cached value instead to avoid writing corrupted values to AUTOC due to bad FW. Emil also add support for disabling link during boot time. Lastly, he provides a patch which adds the MAC type to the version in ethtool_regs which will make it easier to check the MAC type when dumping registers with ethtool. There is a separate ethtool tool patch which is dependent upon Emil's last patch of the series to add the MAC type to the version in ethtool_regs, which will be sent separately. ==================== Signed-off-by: David S.

This will make it easier to check the mac type when dumping registers with ethtool. The drawback of this is that older versions of ethtool will only be able to dump in hex format for 82599 and above when used with the updated driver.

This resulted in a loss of performance when the X540's PPS feature is enabled due to sometimes clearing queue interrupts which resulted in the driver not getting the interrupt for cleaning the q_vector rings often enough. The fix is to simply mask the lower 16bits off so that this handler does not write them in the EICR, which causes them to remain high and be properly handled by the clean_rings interrupt routine as normal.

The code converts the seconds field .tv_sec by multiplying it with NSEC_PER_SEC. However, both operands are of type long, resulting in an unintended overflow.
