2018-01-23i40e/i40evf: Enable NVMUpdate to retrieve AdminQ and add preservation flags ↵Pawel Jablonski
for NVM update This patch adds new I40E_NVMUPD_GET_AQ_EVENT state to allow retrieval of AdminQ events as a result of AdminQ commands sent to firmware. Add preservation flags support on X722 devices for NVM update AdminQ function wrapper. Add new parameter and handling to nvmupdate admin queue function intended to allow nvmupdate tool to configure the preservation flags in the AdminQ command. This is required to implement FlatNVM on X722 devices. Signed-off-by: Pawel Jablonski <pawel.jablonski@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>

2018-01-23ixgbe: add ipsec offload add and remove SAShannon Nelson
Add the functions for setting up and removing offloaded SAs (Security Associations) with the x540 hardware. We set up the callback structure but we don't yet set the hardware feature bit to be sure the XFRM service won't actually try to use us for an offload yet. The software tables are made up to mimic the hardware tables to make it easier to track what's in the hardware, and the SA table index is used for the XFRM offload handle. However, there is a hashing field in the Rx SA tracking that will be used to facilitate faster table searches in the Rx fast path.

Fix bug that causes _absolute_ rtsym sizes of > 8 bytes (as per symbol table) to result in incorrect space used during a TLV-based debug dump. Detail: The size calculation stage calculates the correct size (size of the rtsym address field == 8), while the dump uses the size in the table to calculate the TLV size to reserve. Symbols with size <= 8 are handled OK due to aligning sizes to 8, but including any absolute symbol with listed size > 8 leads to an ENOSPC error during the dump.

Commit bdcf0a423ea1 ("kernel: make groups_sort calling a responsibility group_info allocators") appears to break nfsd rootsquash in a pretty major way. It adds a call to groups_sort() inside the loop that copies/squashes gids, which means the valid gids are sorted along with the following garbage. The net result is that the highest numbered valid gids are replaced with any lower-valued garbage gids, possibly including 0. We should sort only once, after filling in all the gids.

2018-01-22orangefs: initialize op on loop restart in orangefs_devreq_readMartin Brandenburg
In orangefs_devreq_read, there is a loop which picks an op off the list of pending ops. If the loop fails to find an op, there is nothing to read, and it returns EAGAIN. If the op has been given up on, the loop is restarted via a goto. The bug is that the variable which the found op is written to is not reinitialized, so if there are no more eligible ops on the list, the code runs again on the already handled op. This is triggered by interrupting a process while the op is being copied to the client-core. It's a fairly small window, but it's there.

2018-01-22Merge branch 'net-sched-add-extack-support-for-cls-offloads'David S. Miller
Jakub Kicinski says: ==================== net: sched: add extack support for cls offloads I've dropped the tests from the series because test_offloads.py changes will conflict with bpf-next patches. I will send four more patches with tests once bpf-next is merged back, hopefully still making it into 4.16 :) v4: - rebase on top of Alex's changes. --- Quentin says: This series tries to improve user experience when eBPF hardware offload hits error paths at load time. In particular, it introduces netlink extended ack support in the nfp driver. To that aim, transmission of the pointer to the extack object is piped through the `change()` operation of the existing classifiers (patch 1 to 6). Then it is used for TC offload in the nfp driver (patch 8) and in netdevsim (patch 9, selftest in patch 10). Patch 7 adds a helper to handle extack messages in the core when TC offload is disabled on the net device. For completeness extack is propagated for classifiers other than cls_bpf, but it's up to the drivers to make use of it. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Commit "net: igmp: Use correct source address on IGMPv3 reports" introduced a check to validate the source address of locally generated IGMPv3 packets. Instead of checking the local interface address directly, it uses inet_ifa_match(fl4->saddr, ifa), which checks if the address is on the local subnet (or equal to the point-to-point address if used). This breaks for point-to-point interfaces, so check against ifa->ifa_local directly.

2018-01-22net: stmmac: Fix reception of Broadcom switches tagsFlorian Fainelli
Broadcom tags inserted by Broadcom switches put a 4 byte header after the MAC SA and before the EtherType, which may look like some sort of 0 length LLC/SNAP packet (tcpdump and wireshark do think that way). With ACS enabled in stmmac the packets were truncated to 8 bytes on reception, whereas clearing this bit allowed normal reception to occur. In order to make that possible, we need to pass a net_device argument to the different core_init() functions and we are dependent on the Broadcom tagger padding packets correctly (which it now does). To be as little invasive as possible, this is only done for gmac1000 when the network device is DSA-enabled (netdev_uses_dsa() returns true).
