spi: cadence: cache reference clock rate during probe

2021-01-23T14:49:57+00:00

commit 4d163ad79b155c71bf30366dc38f8d2502f78844 upstream. The issue is that using SPI from a callback under the CCF lock will deadlock, since this code uses clk_get_rate().

net: stmmac: Fixed mtu channged by cache aligned

2021-01-23T14:49:56+00:00

[ Upstream commit 5b55299eed78538cc4746e50ee97103a1643249c ] Since the original mtu is not used when the mtu is updated, the mtu is aligned with cache, this will get an incorrect. For example, if you want to configure the mtu to be 1500, but mtu 1536 is configured in fact.

rndis_host: set proper input size for OID_GEN_PHYSICAL_MEDIUM request

2021-01-23T14:49:55+00:00

[ Upstream commit e56b3d94d939f52d46209b9e1b6700c5bfff3123 ] MSFT ActiveSync implementation requires that the size of the response for incoming query is to be provided in the request input length. Failure to set the input size proper results in failed request transfer, where the ActiveSync counterpart reports the NDIS_STATUS_INVALID_LENGTH (0xC0010014L) error. Set the input size for OID_GEN_PHYSICAL_MEDIUM query to the expected size of the response in order for the ActiveSync to properly respond to the request.

netxen_nic: fix MSI/MSI-x interrupts

2021-01-23T14:49:55+00:00

[ Upstream commit a2bc221b972db91e4be1970e776e98f16aa87904 ] For all PCI functions on the netxen_nic adapter, interrupt mode (INTx or MSI) configuration is dependent on what has been configured by the PCI function zero in the shared interrupt register, as these adapters do not support mixed mode interrupts among the functions of a given adapter. Logic for setting MSI/MSI-x interrupt mode in the shared interrupt register based on PCI function id zero check is not appropriate for all family of netxen adapters, as for some of the netxen family adapters PCI function zero is not really meant to be probed/loaded in the host but rather just act as a management function on the device, which caused all the other PCI functions on the adapter to always use legacy interrupt (INTx) mode instead of choosing MSI/MSI-x interrupt mode. This patch replaces that check with port number so that for all type of adapters driver attempts for MSI/MSI-x interrupt modes.

dm integrity: fix flush with external metadata device

2021-01-23T14:49:55+00:00

commit 9b5948267adc9e689da609eb61cf7ed49cae5fa8 upstream. With external metadata device, flush requests are not passed down to the data device. Fix this by submitting the flush request in dm_integrity_flush_buffers. In order to not degrade performance, we overlap the data device flush with the metadata device flush.

usb: ohci: Make distrust_firmware param default to false

commit c4005a8f65edc55fb1700dfc5c1c3dc58be80209 upstream. The 'distrust_firmware' module parameter dates from 2004 and the USB subsystem is a lot more mature and reliable now than it was then. Alter the default to false now.

dm: eliminate potential source of excessive kernel log noise

commit 0378c625afe80eb3f212adae42cc33c9f6f31abf upstream. There wasn't ever a real need to log an error in the kernel log for ioctls issued with insufficient permissions. Simply return an error and if an admin/user is sufficiently motivated they can enable DM's dynamic debugging to see an explanation for why the ioctls were disallowed.
