2021-04-22ice: Advertise virtchnl UDP segmentation offload capabilityBrett Creeley
As the hardware is capable of supporting UDP segmentation offload, add a capability bit to virtchnl.h to communicate this and have the driver advertise its support.

2021-04-22ice: Allow ignoring opcodes on specific VFMichal Swiatkowski
Declare bitmap of allowed commands on VF. Initialize default opcodes list that should be always supported. Declare array of supported opcodes for each caps used in virtchnl code. Change allowed bitmap by setting or clearing corresponding bit to allowlist (bit set) or denylist (bit clear).

2021-04-22ice: warn about potentially malicious VFsVignesh Sridhar
Attempt to detect malicious VFs and, if suspected, log the information but keep going to allow the user to take any desired actions. Potentially malicious VFs are identified by checking if the VFs are transmitting too many messages via the PF-VF mailbox which could cause an overflow of this channel resulting in denial of service. This is done by creating a snapshot or static capture of the mailbox buffer which can be traversed and in which the messages sent by VFs are tracked.

2021-04-22wlcore: Fix buffer overrun by snprintf due to incorrect buffer sizeColin Ian King
The size of the buffer than can be written to is currently incorrect, it is always the size of the entire buffer even though the snprintf is writing as position pos into the buffer. Fix this by setting the buffer size to be the number of bytes left in the buffer, namely sizeof(buf) - pos.

2021-04-22ath9k: Fix error check in ath9k_hw_read_revisions() for PCI devicesToke Høiland-Jørgensen
When the error check in ath9k_hw_read_revisions() was added, it checked for -EIO which is what ath9k_regread() in the ath9k_htc driver uses. However, for plain ath9k, the register read function uses ioread32(), which just returns -1 on error. So if such a read fails, it still gets passed through and ends up as a weird mac revision in the log output. Fix this by changing ath9k_regread() to return -1 on error like ioread32() does, and fix the error check to look for that instead of -EIO.
