2019-01-28qed: Fix bug in tx promiscuous mode settingsManish Chopra1-1/+6
When running tx switched traffic between VNICs created via a bridge(to which VFs are added), adapter drops the unicast packets in tx flow due to VNIC's ucast mac being unknown to it. But VF interfaces being in promiscuous mode should have caused adapter to accept all the unknown ucast packets. Later, it was found that driver doesn't really configure tx promiscuous mode settings to accept all unknown unicast macs. This patch fixes tx promiscuous mode settings to accept all unknown/unmatched unicast macs and works out the scenario.

2019-01-28gpio: vf610: Mask all GPIO interruptsAndrew Lunn1-0/+5
On SoC reset all GPIO interrupts are disable. However, if kexec is used to boot into a new kernel, the SoC does not experience a reset. Hence GPIO interrupts can be left enabled from the previous kernel. It is then possible for the interrupt to fire before an interrupt handler is registered, resulting in the kernel complaining of an "unexpected IRQ trap", the interrupt is never cleared, and so fires again, resulting in an interrupt storm. Disable all GPIO interrupts before registering the GPIO IRQ chip.

This reverts commit 5f5991f36dce1e69dd8bd7495763eec2e28f08e7. With the original commit, eswitch instance will not be initialized for a function which is vport group manager but not eswitch manager such as host PF on SmartNIC (BlueField) card. This will result in a kernel crash when such a vport group manager is trying to access vports in its group. E.g, PF vport manager (not eswitch manager) tries to configure the MAC of its VF vport, a kernel trace will happen similar as bellow: BUG: unable to handle kernel NULL pointer dereference at 0000000000000000 ...

The intention of the flow_is_supported was to disable the entire tree and methods that allow raw flow creation, but the grammar syntax has this disable the entire UVERBS_FLOW object. Since the method requires a MLX5_IB_OBJECT_FLOW_MATCHER there is no need to do anything, as it is automatically disabled when matchers are disabled. This restores the ability to create flow steering rules on representors via regular verbs.

2019-01-25IB/uverbs: Fix OOPs upon device disassociationYishai Hadas1-4/+3
The async_file might be freed before the disassociation has been ended, causing qp shutdown to use after free on it. Since uverbs_destroy_ufile_hw is not a fence, it returns if a disassociation is ongoing in another thread. It has to be written this way to avoid deadlock. However this means that the ufile FD close cannot destroy anything that may still be used by an active kref, such as the the async_file. To fix that move the kref_put() to be in ib_uverbs_release_file().

The next patch is by Oliver Hartkopp for the bcm that adds sanity checks for the timer value before using it to detect potential interger overflows. The last two patches are for the flexcan driver, YueHaibing's patch fixes the the return value in the error path of the flexcan_setup_stop_mode() function. The second patch is by Uwe Kleine-König and fixes a NULL pointer deref on older flexcan cores in flexcan_chip_start(). ==================== Signed-off-by: David S. Miller <[email protected]>
2019-01-24net/mlx4_core: Fix error handling when initializing CQ bufs in the driverJack Morgenstein1-2/+4
Procedure mlx4_init_user_cqes() handles returns by copy_to_user incorrectly. copy_to_user() returns the number of bytes not copied. Thus, a non-zero return should be treated as a -EFAULT error (as is done elsewhere in the kernel). However, mlx4_init_user_cqes() error handling simply returns the number of bytes not copied (instead of -EFAULT). Note, though, that this is a harmless bug: procedure mlx4_alloc_cq() (which is the only caller of mlx4_init_user_cqes()) treats any non-zero return as an error, but that returned error value is processed internally, and not passed further up the call stack. In addition, fixes the following sparse warning: warning: incorrect type in argument 1 (different address spaces) expected void [noderef] <asn:1>*to got void *buf Fixes: e45678973dcb ("{net, IB}/mlx4: Initialize CQ buffers in the driver when possible") Reported by: Dan Carpenter <[email protected]> Signed-off-by: Jack Morgenstein <[email protected]> Signed-off-by: Tariq Toukan <[email protected]> Signed-off-by: David S.
