When an XDR-encoded Kerberos 5 ticket is added as an rxrpc-type key, the expiry time should be drawn from the k5 part of the token union (which was what was filled in), rather than the kad part of the union. Reported-by:

Since the 'expiry' variable of 'struct key_preparsed_payload' has been changed to 'time64_t' type, which is year 2038 safe on 32bits system. In net/rxrpc subsystem, we need convert 'u32' type to 'time64_t' type when copying ticket expires time to 'prep->expiry', then this patch introduces two helper functions to help convert 'u32' to 'time64_t' type. This patch also uses ktime_get_real_seconds() to get current time instead of get_seconds() which is not year 2038 safe on 32bits system. Signed-off-by:

This patch adds support for offloading TC based flow rules and actions for the 'flower' classifier in the bnxt_en driver. It includes logic to parse flow rules and actions received from the TC subsystem, store them and issue the corresponding hwrm_cfa_flow_alloc/free FW cmds. L2/IPv4/IPv6 flows and drop, redir, vlan push/pop actions are supported in this patch. In this patch the hwrm_cfa_flow_xxx routines are just stubs. The code for these routines is introduced in the next patch for easier review. Also, the code to query the TC/flower action stats will be introduced in a subsequent patch. Signed-off-by:

The routine bnxt_link_bp_to_dl() is used to set the devlink ptr in bnxt struct (bp) and also to set the bnxt back ptr in the devlink struct. If devlink_register() fails, bp->dl must be cleared which is not happening currently. This patch fixes bnxt_link_bp_to_dl() to clear bp->dl by passing a NULL dl ptr.

If we cannot allocate RX buffers in the NAPI poll loop when processing an RX event, the current code does not count that event towards the NAPI budget. This can cause us to potentially loop forever in NAPI if we consistently cannot allocate new buffers. Improve it by counting -ENOMEM event as 1 towards the NAPI budget.

When the number of TX rings is changed (e.g. ethtool -L, enabling XDP TX rings, etc), the current code tries to reserve the new number of TX rings before closing and re-opening the NIC. If we are unable to reserve the new TX rings, we abort the operation and keep the current TX rings. The problem is that the firmware will disable the current TX rings even when it cannot reserve the new set of TX rings. We fix it as follows: 1. Instead of reserving the new set of TX rings, just ask the firmware to check if the new set of TX rings is available. There is a flag in the firmware message to do that. If not available, abort and the current TX rings will not be disabled. 2. Do the actual TX ring reservation in the path that opens the NIC. We keep the number of TX rings currently successfully reserved. If the number of TX rings is different than the reserved TX rings, we call firmware and reserve again. Signed-off-by:

Samuel Mendoza-Jonas says: ==================== NCSI VLAN Filtering Support This series (mainly patch 2) adds VLAN filtering to the NCSI implementation. A fair amount of code already exists in the NCSI stack for VLAN filtering but none of it is actually hooked up. This goes the final mile and fixes a few bugs in the existing code found along the way (patch 1). Patch 3 adds the appropriate flag and callbacks to the ftgmac100 driver to enable filtering as it's a large consumer of NCSI (and what I've been testing on). v3: - Add comment describing change to ncsi_find_filter() - Catch NULL in clear_one_vid() from ncsi_get_filter() - Simplify state changes when kicking updated channel ==================== Signed-off-by:

Register the ndo_vlan_rx_{add,kill}_vid callbacks and set the NETIF_F_HW_VLAN_CTAG_FILTER if NCSI is available. This allows the VLAN core to notify the NCSI driver when changes occur so that the remote NCSI channel can be properly configured to filter on the set VLAN tags. Signed-off-by:

Make use of the ndo_vlan_rx_{add,kill}_vid callbacks to have the NCSI stack process new VLAN tags and configure the channel VLAN filter appropriately. Several VLAN tags can be set and a "Set VLAN Filter" packet must be sent for each one, meaning the ncsi_dev_state_config_svf state must be repeated. An internal list of VLAN tags is maintained, and compared against the current channel's ncsi_channel_filter in order to keep track within the state. VLAN filters are removed in a similar manner, with the introduction of the ncsi_dev_state_config_clear_vids state. The maximum number of VLAN tag filters is determined by the "Get Capabilities" response from the channel. Signed-off-by:

Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2017-08-27 This series contains updates to i40e and i40evf only. Sudheer updates code comments and state variable so that adminq_subtask will have accutate information whenever it gets scheduled. Mariusz stores information about FEC modes, to be used to printing link states information, so that we do not need to call admin queue when reporting link status. Adds VF support for controlling VLAN tag stripping via ethtool. Jake provides the majority of changes in this series, starting with increasing the size of the prefix buffer so that it can hold enough characters for every possible input, which prevents snprintf truncation. Fixed other string truncation errors/warnings produced by GCC 7.x. Removed an unnecessary workaround for resetting XPS. Fixed an issue where there is a mismatched affinity mask value, so initialize the value to cpu_possible_mask and invert the logic for checking incorrect CPU vs IRQ affinity so that the exceptional case is handled at the check. Removed ULTRA latency mode due to several issues found and will be looking at better solution for small packet workloads. Akeem fixes an issue where the incorrect flag was being used to set promiscuous mode for unicast, which was enabling promiscuous mode only for multicast instead of unicast. Carolyn fixes an issue where an error return value is set, but this value can be overwritten before we actually do exit the function. So remove the error code assignment and add code comments for better understanding on why we do not need to set and return the error. ==================== Signed-off-by:
