Sometimes an in-progress call will stop responding on the fileserver when
the fileserver quietly cancels the call with an internally marked abort
(RX_CALL_DEAD), without sending an ABORT to the client.

This causes the client's call to eventually expire from lack of incoming
packets directed its way, which currently leads to it being cancelled
locally with ETIME.  Note that it's not currently clear as to why this
happens as it's really hard to reproduce.

The rotation policy implement by kAFS, however, doesn't differentiate
between ETIME meaning we didn't get any response from the server and ETIME
meaning the call got cancelled mid-flow.  The latter leads to an oops when
fetching data as the rotation partially resets the afs_read descriptor,
which can result in a cleared page pointer being dereferenced because that
page has already been filled.

Handle this by the following means:

 (1) Set a flag on a call when we receive a packet for it.

 (2) Store the highest packet serial number so far received for a call
     (bearing in mind this may wrap).

 (3) If, when the "not received anything recently" timeout expires on a
     call, we've received at least one packet for a call and the connection
     as a whole has received packets more recently than that call, then
     cancel the call locally with ECONNRESET rather than ETIME.

     This indicates that the call was definitely in progress on the server.

 (4) In kAFS, if the rotation algorithm sees ECONNRESET rather than ETIME,
     don't try the next server, but rather abort the call.

     This avoids the oops as we don't try to reuse the afs_read struct.
     Rather, as-yet ungotten pages will be reread at a later data.

Also:

 (5) Add an rxrpc tracepoint to log detection of the call being reset.

Without this, I occasionally see an oops like the following:

Browsing  thru the driver disassembly, I noticed that ARM gcc generated
no  code  whatsoever for sh_eth_soft_swap() while building a little-endian
kernel -- apparently __LITTLE_ENDIAN__ was not being #define'd, however
it got implicitly #define'd when building with the SH gcc (I could only
find the explicit #define __LITTLE_ENDIAN that was #include'd when building
a little-endian kernel).  Luckily, the Ether controller  only doing big-
endian DMA is encountered on the early SH771x SoCs only and all ARM SoCs
implement EDMR.DE and thus set 'sh_eth_cpu_data::hw_swap'. But anyway, we
need to fix the #ifdef inside sh_eth_soft_swap() to something that would
work on all architectures...

mlxsw: Fixes in offloading of mirror-to-gretap

Petr says:

These two patches fix issues in offloading of mirror-to-gretap when
bridge is present in the underlay.

In patch #1, reconsideration of SPAN configuration is not done right at
the point that SWITCHDEV_OBJ_ID_PORT_VLAN deletion notification is
distributed, but is postponed, because the notifications are actually
distributed before the relevant change is implemented in the bridge.

In patch #2, a problem in configuring VLAN tagging in situations when a
VLAN device is on top of an 802.1Q bridge whose egress port is marked as
"egress untagged". In that case, mlxsw would neglect to suppress the
tagging implicitly assumed after the VLAN device was seen.
====================
Signed-off-by: NDavid S. Miller <davem@davemloft.net>

When offloading mirroring to gretap or ip6gretap netdevices, an 802.1q
bridge is one of the soft devices permissible in the underlay when
resolving the packet path. After the packet path is resolved to a
particular bridge egress device, flags on packet VLAN determine whether
the egressed packet should be tagged.

The current logic however only ever sets the VLAN tag, never suppresses
it. Thus if there's a VLAN netdevice above the bridge that determines
the packet VLAN, that VLAN is never unset, and mirroring is configured
with VLAN tagging.

Fix by setting the packet VLAN on both branches: set to zero (for unset)
when BRIDGE_VLAN_INFO_UNTAGGED, copy the resolved VLAN (e.g. from bridge
PVID) otherwise.

Add regression tests for PF_PACKET transmission using packet_snd.

The TPACKET ring interface has tests for transmission and reception.
This is an initial stab at the same for the send call based interface.

Packets are sent over loopback, then read twice. The entire packet is
read from another packet socket and compared. The packet is also
verified to arrive at a UDP socket for protocol conformance.

The test sends a packet over loopback, testing the following options
(not the full cross-product):

- SOCK_DGRAM
- SOCK_RAW
- vlan tag
- qdisc bypass
- bind() and sendto()
- virtio_net_hdr
- csum offload (NOT actual csum feature, ignored on loopback)
- gso

Besides these basic functionality tests, the test runs from a set
of bounds checks, positive and negative. Running over loopback, which
has dev->min_header_len, it cannot generate variable length hhlen.

Verify that udpgso can generate segments smaller than device mtu, down
to the extreme case of 1B gso_size.

Verify that irrespective of gso_size, udpgso restricts the number of
segments it will generate per call (UDP_MAX_SEGMENTS).
