Currently macvlan devices do not set their hw_enc_features making encapsulated Tx packets resort to SW fallbacks. Add encapsulation GSO offloads to ->features as is done for the other GSOs and set ->hw_enc_features. Signed-off-by:

Adding a lock around one of the assignments prevents gcc from tracking the state of the local 'fibmatch' variable, so it can no longer prove that 'dst' is always initialized, leading to a bogus warning: net/ipv6/route.c: In function 'inet6_rtm_getroute': net/ipv6/route.c:3659:2: error: 'dst' may be used uninitialized in this function [-Werror=maybe-uninitialized] This moves the other assignment into the same lock to shut up the warning.

This patch fixes the missing u64_stats_fetch_begin_irq() while trying to atomically do 64-bit RX/TX fetch. We did not get any error during test as our SoC is 64-bit so all of these seq/lock operations results in NOOP. As such, this seq lock supports has been added for the sake of completion if this code ever runs on 32-bit platform and we are trying to do 64-bit stats fetch.

Julian Wiedmann says: ==================== s390/net: more updates for 4.14 please apply another batch of qeth patches for net-next. This reworks the xmit path for L2 OSAs to use skb_cow_head() instead of skb_realloc_headroom(). ==================== Signed-off-by:
David S. Miller <davem@davemloft.net>

Julian Wiedmann authored
Taking a full copy via skb_realloc_headroom() on every xmit is overkill and wastes CPU time; all we actually need is to push on the qeth_hdr. So rework the L2 OSA TX path to avoid the copy. Minor complications arise because struct qeth_hdr must not cross a page boundary. So add a new helper qeth_push_hdr() that catches this, and falls back to the hdr cache that we already use for IQDs. This change uncovered that qeth's TX completion takes rather long. Now that we no longer free the original skb straight away and thus call skb->destructor later than before, throughput regresses significantly. For now, restore old behaviour by adding an explicit skb_orphan(), and a big TODO to improve the TX completion time. Tested-by:

This is a prerequisite for unifying the code to build header elements. The TSO header has a different size, so we can no longer rely on implicitly adding the size of a normal qeth_hdr. No functional change. Signed-off-by:

For TSO we need to skip the skb's qeth/IP/TCP headers when mapping it into buffer elements. Instead of (mis)using skb_pull(), pass a corresponding offset to fill_buffer() like we already do for IQDs. No actual change in the resulting TSO buffers. Signed-off-by:

The TSO code already calculates the length of its header element, no need to duplicate this in the low-level code again. Use this opportunity to make hd_len unsigned, and for TSO match its calculation to what tso_fill_header() does. No functional change. Signed-off-by:

For IQD we already need to fix up the qeth_hdr's length field, and future changes will require more flexibility for OSA as well. The device-specific path knows best what header length it requires, so just pass it from there. While at it, remove the unused qeth_card parameter. No functional change. Signed-off-by:

The Broadcom controller on the Raspberry Pi3 sends an empty packet with packet type 0x00 after launching the firmware. This will cause logging of errors. Bluetooth: hci0: Frame reassembly failed (-84) Since this seems to be an intented behaviour of the controller, handle it gracefully by parsing that empty packet with packet type 0x00 and then just simply report it as diagnostic packet. With that change no errors are logging and the packet itself is actually recorded in the Bluetooth monitor traces. < HCI Command: Broadcom Launch RAM (0x3f|0x004e) plen 4 Address: 0xffffffff > HCI Event: Command Complete (0x0e) plen 4 Broadcom Launch RAM (0x3f|0x004e) ncmd 1 Status: Success (0x00) = Vendor Diagnostic (len 0) < HCI Command: Broadcom Update UART Baud Rate (0x3f|0x0018) plen 6 00 00 00 10 0e 00 ...... > HCI Event: Command Complete (0x0e) plen 4 Broadcom Update UART Baud Rate (0x3f|0x0018) ncmd 1 Status: Success (0x00) < HCI Command: Reset (0x03|0x0003) plen 0 > HCI Event: Command Complete (0x0e) plen 4 Reset (0x03|0x0003) ncmd 1 Status: Success (0x00) Signed-off-by:
