      geneve: allow to clear ttl inherit · a97d97ba
      Hangbin Liu authored 
      As Michal remaind, we should allow to clear ttl inherit. Then we will
have three states:

1. set the flag, and do ttl inherit.
2. do not set the flag, use configured ttl value, or default ttl (0) if
   not set.
3. disable ttl inherit, use previous configured ttl value, or default ttl (0).

Fixes: 52d0d404 ("geneve: add ttl inherit support")

      tc: Add support for configuring the taprio scheduler · 5a781ccb
      Vinicius Costa Gomes authored 
      This traffic scheduler allows traffic classes states (transmission
allowed/not allowed, in the simplest case) to be scheduled, according
to a pre-generated time sequence. This is the basis of the IEEE
802.1Qbv specification.

Example configuration:

tc qdisc replace dev enp3s0 parent root handle 100 taprio \
          num_tc 3 \
	  map 2 2 1 0 2 2 2 2 2 2 2 2 2 2 2 2 \
	  queues 1@0 1@1 2@2 \
	  base-time 1528743495910289987 \
	  sched-entry S 01 300000 \
	  sched-entry S 02 300000 \
	  sched-entry S 04 300000 \
	  clockid CLOCK_TAI

The configuration format is similar to mqprio. The main difference is
the presence of a schedule, built by multiple "sched-entry"
definitions, each entry has the following format:

     sched-entry <CMD> <GATE MASK> <INTERVAL>

The only supported <CMD> is "S", which means "SetGateStates",
following the IEEE 802.1Qbv-2015 definition (Table 8-6). <GATE MASK>
is a bitmask where each bit is a associated with a traffic class, so
bit 0 (the least significant bit) being "on" means that traffic class
0 is "active" for that schedule entry. <INTERVAL> is a time duration
in nanoseconds that specifies for how long that state defined by <CMD>
and <GATE MASK> should be held before moving to the next entry.

This schedule is circular, that is, after the last entry is executed
it starts from the first one, indefinitely.

The other parameters can be defined as follows:

 - base-time: specifies the instant when the schedule starts, if
  'base-time' is a time in the past, the schedule will start at

 	      base-time + (N * cycle-time)

   where N is the smallest integer so the resulting time is greater
   than "now", and "cycle-time" is the sum of all the intervals of the
   entries in the schedule;

 - clockid: specifies the reference clock to be used;

The parameters should be similar to what the IEEE 802.1Q family of
specification defines.

      This patch adds support for following generic permanent mode
devlink parameters. They can be modified using devlink param
commands.

msix_vec_per_pf_max - This param sets the number of MSIX vectors
that the device requests from the host on driver initialization.
This value is set in the device which limits MSIX vectors per PF.

msix_vec_per_pf_min - This param sets the number of minimal MSIX
vectors required for the device initialization. Value 0 indicates
a default value is selected. This value is set in the device which
limits MSIX vectors per PF.

      qed: Avoid implicit enum conversion in qed_ooo_submit_tx_buffers · 8fa74e3c
      Nathan Chancellor authored 
      Clang warns when one enumerated type is implicitly converted to another.

drivers/net/ethernet/qlogic/qed/qed_ll2.c:799:32: warning: implicit
conversion from enumeration type 'enum core_tx_dest' to different
enumeration type 'enum qed_ll2_tx_dest' [-Wenum-conversion]

                               ~ ~~~~~~~~~~~~^~~~~~~
1 warning generated.

Fix this by using a switch statement to convert between the enumerated
values since they are not 1 to 1, which matches how the rest of the
driver handles this conversion.

====================
mlx5-updates-2018-10-03

mlx5 core driver and ethernet netdev updates, please note there is a small
devlink releated update to allow extack argument to eswitch operations.

From Eli Britstein,
1) devlink: Add extack argument to the eswitch related operations
2) net/mlx5e: E-Switch, return extack messages for failures in the e-switch devlink callbacks
3) net/mlx5e: Add extack messages for TC offload failures

From Eran Ben Elisha,
4) mlx5e: Add counter for aRFS rule insertion failures

From Feras Daoud
5) Fast teardown support for mlx5 device
This change introduces the enhanced version of the "Force teardown" that
allows SW to perform teardown in a faster way without the need to reclaim
all the FW pages.
Fast teardown provides the following advantages:
    1- Fix a FW race condition that could cause command timeout
    2- Avoid moving to polling mode
    3- Close the vport to prevent PCI ACK to be sent without been scatter
    to memory

      David S. Miller authored 
      David Howells says:

====================
rxrpc: Development

Here are some development patches for AF_RXRPC.  The most significant points
are:

 (1) Change the tracepoint that indicates a packet has been transmitted
     into one that indicates a packet is about to be transmitted.  Without
     this, the response tracepoint may occur first if the round trip is
     fast enough.

 (2) Sort out AFS address list handling to better enforce maximum capacity
     to use helper functions to fill them and to do an insertion sort to
     order them.  This is here to make (3) easier.

 (3) Keep AF_INET addresses as AF_INET addresses rather than converting
     them to AF_INET6 in both AF_RXRPC and kAFS.  I hadn't realised that a
     UDP6 socket would just call down into UDP4 if given an AF_INET
     address.

 (4) Allow the timestamp on the first DATA packet of a reply to be
     retrieved by a kernel service.  This will give the kAFS a more
     accurate base from which to calculate the callback promise expiration.

 (5) Allow the rxrpc protocol epoch value to be retrieved from an incoming
     call.  This will allow kAFS to determine if the fileserver restarted
     and if two addresses apparently assigned to the same fileserver
     actually are different boxes.

      dns: Allow the dns resolver to retrieve a server set · bbb4c432
      David Howells authored 
      Allow the DNS resolver to retrieve a set of servers and their associated
addresses, ports, preference and weight ratings.

In terms of communication with userspace, "srv=1" is added to the callout
string (the '1' indicating the maximum data version supported by the
kernel) to ask the userspace side for this.

If the userspace side doesn't recognise it, it will ignore the option and
return the usual text address list.

If the userspace side does recognise it, it will return some binary data
that begins with a zero byte that would cause the string parsers to give an
error.  The second byte contains the version of the data in the blob (this
may be between 1 and the version specified in the callout data).  The
remainder of the payload is version-specific.

In version 1, the payload looks like (note that this is packed):

	u8	Non-string marker (ie. 0)
	u8	Content (0 => Server list)
	u8	Version (ie. 1)
	u8	Source (eg. DNS_RECORD_FROM_DNS_SRV)
	u8	Status (eg. DNS_LOOKUP_GOOD)
	u8	Number of servers
	foreach-server {
		u16	Name length (LE)
		u16	Priority (as per SRV record) (LE)
		u16	Weight (as per SRV record) (LE)
		u16	Port (LE)
		u8	Source (eg. DNS_RECORD_FROM_NSS)
		u8	Status (eg. DNS_LOOKUP_GOT_NOT_FOUND)
		u8	Protocol (eg. DNS_SERVER_PROTOCOL_UDP)
		u8	Number of addresses
		char[]	Name (not NUL-terminated)
		foreach-address {
			u8		Family (AF_INET{,6})
			union {
				u8[4]	ipv4_addr
				u8[16]	ipv6_addr
			}
		}
	}

This can then be used to fetch a whole cell's VL-server configuration for
AFS, for example.
