Note: get_flags was actually broken, because it should return the flags capped with vlan_features. This is now done implicitly by limiting netdev->hw_features. RX checksumming offload control is (and was) broken, as there was no way before to say whether it's done for tagged packets.

Not tested in any way. The original code for offload setting seems broken as it resets the features on every netback reconnect. This will set GSO_ROBUST at device creation time (earlier than connect time). RX checksum offload is forced on - so advertise as it is.

There's a race (not fixed here) in smsc75xx in setting RFE_CTL that's not properly handled via rfe_ctl_lock. Spinlock is not a good tool here, as this has to wait for URB completion (or maybe just submission) after issuing register write request. Otherwise, the rfe_ctl might be changed just after spin_unlock() and device left programmed with other value. smsc95xx has increased hard_header_len for the case of TX checksumming. smsc75xx is fixed to advertise IP+IPV6_CSUM instead of HW_CSUM as it does not use csum_start/csum_offset.

The IRQF_SAMPLE_RANDOM flag is marked as deprecated and will be removed. Every input point to the kernel's entropy pool have to better document the type of entropy source it is. drivers/char/random.c now implements a set of interfaces that can be used for devices to collect enviromental noise. IRQF_SAMPLE_RANDOM will be replaced with these add_*_randomness exported functions. Network drivers are not a good source of entropy. They use as a source of entropy essentially a remote host. Which means that the source of entropy can be potentially controlled by an attacker. Also, with heavy workloads the entropy decreases due to less hardware interrupts happening thanks to irq mitigation and NAPI. If a system relies in its network interface as a entropy source it has a false sense of security. Systems that don't have devices whose drivers are good sources of entropy, should either use a hardware random number generator or feed the kernel's entropy pool from userspace using other sources of entropy such as EGD, video_entropyd, timer_entropyd and audio-entropyd.

Current enic code only supports ASSOCIATE and DISASSOCIATE port profile operations. This patch adds enic support for port profile PORT_REQUEST_PREASSOCIATE_RR operation. The VIC adapter (8021qbh) is capable of handling port profile requests done in two steps namely PREASSOCIATE_RR and ASSOCIATE today. The motivation to support PREASSOCIATE_RR comes mainly from its use as an optimization during VM migration ie, to do resource reservation on destination host before resources on source host are released. PREASSOCIATE_RR is a VDP operation and according to the latest at IEEE, 8021qbh will also need to support VDP commands. In addition to handling the new PORT_REQUEST_PREASSOCIATE_RR operation this patch also does the below: - Introduces handlers for PORT_REQUEST operations - Moves most of the port profile handling code to new files enic_pp.[ch] - Uses new fw devcmds for port profile operations Signed-off-by: NRoopa Prabhu <roprabhu@cisco.com> Signed-off-by: NDavid Wang <dwang2@cisco.com> Signed-off-by: NChristian Benvenuti <benve@cisco.com> Signed-off-by: NDavid S.

This patch introduces new fw devcmds for port profile handling. These new commands are similar to the current fw commands for port profile handling. The only difference being that the new commands split the existing port profile handling devcmds into multiple fw commands, giving the driver finer control over port profile operations.

Commits 01a16b21 (netlink: kill eff_cap from struct netlink_skb_parms) and c53fa1ed (netlink: kill loginuid/sessionid/sid members from struct netlink_skb_parms) removed some members from struct netlink_skb_parms that depend on the current context, all netlink users are now required to do synchronous message processing. connector however queues received messages and processes them in a work queue, which is not valid anymore. This patch converts connector to do synchronous message processing by invoking the registered callback handler directly from the netlink receive function. In order to avoid invoking the callback with connector locks held, a reference count is added to struct cn_callback_entry, the reference is taken when finding a matching callback entry on the device's queue_list and released after the callback handler has been invoked.
