Using skb_csum_is_sctp is a easier way to validate it's a SCTP CRC checksum offload packet, and there is no need to parse the packet to check its proto field, especially when it's a UDP or GRE encapped packet. So this patch also makes igb support SCTP CRC checksum offload for UDP and GRE encapped packets.

2021-01-19vhost_net: avoid tx queue stuck when sendmsg failsYunjian Wang
Currently the driver doesn't drop a packet which can't be sent by tun (e.g bad packet). In this case, the driver will always process the same packet lead to the tx queue stuck. To fix this issue: 1. in the case of persistent failure (e.g bad packet), the driver can skip this descriptor by ignoring the error. 2. in the case of transient failure (e.g -ENOBUFS, -EAGAIN and -ENOMEM), the driver schedules the worker to try again.

2021-01-18net/bonding: Implement TLS TX device offloadTariq Toukan
Implement TLS TX device offload for bonding interfaces. This allows kTLS sockets running on a bond to benefit from the device offload on capable lower devices. To allow a simple and fast maintenance of the TLS context in SW and lower devices, we bind the TLS socket to a specific lower dev. To achieve a behavior similar to SW kTLS, we support only balance-xor and 802.3ad modes, with xmit_hash_policy=layer3+4. This is enforced in bond_sk_check(), done in a previous patch. For the above configuration, the SW implementation keeps picking the same exact lower dev for all the socket's SKBs. The device offload behaves similarly, making the decision once at the connection creation. Per socket, the TLS module should work directly with the lowest netdev in chain, to call the tls_dev_ops operations. As the bond interface is being bypassed by the TLS module, interacting directly against the lower devs, there is no way for the bond interface to disable its device offload capabilities, as long as the mode/policy config allows it. Hence, the feature flag is not directly controllable, but just reflects the current offload status based on the logic under bond_sk_check().

mv88e6xxx_port_vlan_join checks whether the VTU already contains an entry for the given vid (via mv88e6xxx_vtu_getnext), and if so, merely changes the relevant .member[] element and loads the updated entry into the VTU. However, at least for the mv88e6250, the on-stack struct mv88e6xxx_vtu_entry vlan never has its .state[] array explicitly initialized, neither in mv88e6xxx_port_vlan_join() nor inside the getnext implementation. So the new entry has random garbage for the STU bits, breaking VLAN filtering. When the VTU entry is initially created, those bits are all zero, and we should make sure to keep them that way when the entry is updated.

2021-01-18net: ipa: allow arbitrary number of interconnectsAlex Elder
Currently we assume that the IPA hardware has exactly three interconnects. But that won't be guaranteed for all platforms, so allow any number of interconnects to be specified in the configuration data. For each platform, define an array of interconnect data entries (still associated with the IPA clock structure), and record the number of entries initialized in that array. Loop over all entries in this array when initializing, enabling, disabling, or tearing down the set of interconnects. With this change we no longer need the ipa_interconnect_id enumerated type, so get rid of it. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: Jakub Kicinski <kuba@kernel.org>

In fact, only the PRECHANGEUPPER should have had that check. When we ignore all events that are not for us, we miss the fact that the upper of the LAG changes, and the bonding interface gets enslaved to a bridge.

2021-01-18platform/x86: intel-vbtn: Drop HP Stream x360 Convertible PC 11 from allow-listHans de Goede
THe HP Stream x360 Convertible PC 11 DSDT has the following VGBS function: Method (VGBS, 0, Serialized) { If ((^^PCI0.LPCB.EC0.ROLS == Zero)) { VBDS = Zero } Else { VBDS = Zero } Return (VBDS) /* \_SB_.VGBI.VBDS */ } Which is obviously wrong, because it always returns 0 independent of the 2-in-1 being in laptop or tablet mode. This causes the intel-vbtn driver to initially report SW_TABLET_MODE = 1 to userspace, which is known to cause problems when the 2-in-1 is actually in laptop mode. During earlier testing this turned out to not be a problem because the 2-in-1 would do a Notify(..., 0xCC) or Notify(..., 0xCD) soon after the intel-vbtn driver loaded, correcting the SW_TABLET_MODE state. Further testing however has shown that this Notify() soon after the intel-vbtn driver loads, does not always happen. When the Notify does not happen, then intel-vbtn reports SW_TABLET_MODE = 1 resulting in a non-working touchpad. IOW the tablet-mode reporting is not reliable on this device, so it should be dropped from the allow-list, fixing the touchpad sometimes not working.
