      nfp: flower: set tunnel ttl value to net default · 50a5852a
      John Hurley authored 
      Firmware requires that the ttl value for an encapsulating ipv4 tunnel
header be included as an action field. Prior to the support of Geneve
tunnel encap (when ttl set was removed completely), ttl value was
extracted from the tunnel key. However, tests have shown that this can
still produce a ttl of 0.

Fix the issue by setting the namespace default value for each new tunnel.
Follow up patch for net-next will do a full route lookup.

Fixes: 3ca3059d ("nfp: flower: compile Geneve encap actions")
Fixes: b27d6a95 ("nfp: compile flower vxlan tunnel set actions")

      net/tls: Don't recursively call push_record during tls_write_space callbacks · c212d2c7
      Dave Watson authored 
      It is reported that in some cases, write_space may be called in
do_tcp_sendpages, such that we recursively invoke do_tcp_sendpages again:

[  660.468802]  ? do_tcp_sendpages+0x8d/0x580
[  660.468826]  ? tls_push_sg+0x74/0x130 [tls]
[  660.468852]  ? tls_push_record+0x24a/0x390 [tls]
[  660.468880]  ? tls_write_space+0x6a/0x80 [tls]
...

tls_push_sg already does a loop over all sending sg's, so ignore
any tls_write_space notifications until we are done sending.
We then have to call the previous write_space to wake up
poll() waiters after we are done with the send loop.

      ipv6: Allow non-gateway ECMP for IPv6 · edd7ceb7
      Thomas Winter authored 
      It is valid to have static routes where the nexthop
is an interface not an address such as tunnels.
For IPv4 it was possible to use ECMP on these routes
but not for IPv6.

      ethtool: fix a potential missing-check bug · d656fe49
      Wenwen Wang authored 
      In ethtool_get_rxnfc(), the object "info" is firstly copied from
user-space. If the FLOW_RSS flag is set in the member field flow_type of
"info" (and cmd is ETHTOOL_GRXFH), info needs to be copied again from
user-space because FLOW_RSS is newer and has new definition, as mentioned
in the comment. However, given that the user data resides in user-space, a
malicious user can race to change the data after the first copy. By doing
so, the user can inject inconsistent data. For example, in the second
copy, the FLOW_RSS flag could be cleared in the field flow_type of "info".
In the following execution, "info" will be used in the function
ops->get_rxnfc(). Such inconsistent data can potentially lead to unexpected
information leakage since ops->get_rxnfc() will prepare various types of
data according to flow_type, and the prepared data will be eventually
copied to user-space. This inconsistent data may also cause undefined
behaviors based on how ops->get_rxnfc() is implemented.

This patch simply re-verifies the flow_type field of "info" after the
second copy. If the value is not as expected, an error code will be
returned.

The 3rd system call looks odd :

This patch makes sure bound checking is using an unsigned compare.

      net: support compat 64-bit time in {s,g}etsockopt · 988bf724
      Lance Richardson authored 
      For the x32 ABI, struct timeval has two 64-bit fields. However
the kernel currently interprets the user-space values used for
the SO_RCVTIMEO and SO_SNDTIMEO socket options as having a pair
of 32-bit fields.

When the seconds portion of the requested timeout is less than 2**32,
the seconds portion of the effective timeout is correct but the
microseconds portion is zero.  When the seconds portion of the
requested timeout is zero and the microseconds portion is non-zero,
the kernel interprets the timeout as zero (never timeout).

Fix by using 64-bit time for SO_RCVTIMEO/SO_SNDTIMEO as required
for the ABI.

The code included below demonstrates the problem.

      sctp: clear the new asoc's stream outcnt in sctp_stream_update · 6a9a27d5

      When processing a duplicate cookie-echo chunk, sctp moves the new

But now after this move, the new temp asoc's stream->outcnt is not
cleared while stream->out is set to NULL, which would cause a same
crash as the one fixed in Commit 79d08951 ("sctp: fix error

This fix is to clear this outcnt in sctp_stream_update.

      sctp: handle two v4 addrs comparison in sctp_inet6_cmp_addr · d625329b
      Xin Long authored 
      Since sctp ipv6 socket also supports v4 addrs, it's possible to
compare two v4 addrs in pf v6 .cmp_addr, sctp_inet6_cmp_addr.

However after Commit 1071ec9d ("sctp: do not check port in
sctp_inet6_cmp_addr"), it no longer calls af1->cmp_addr, which
in this case is sctp_v4_cmp_addr, but calls __sctp_v6_cmp_addr
where it handles them as two v6 addrs. It would cause a out of
bounds crash.

syzbot found this crash when trying to bind two v4 addrs to a
v6 socket.

This patch fixes it by adding the process for two v4 addrs in
sctp_inet6_cmp_addr.

Fixes: 1071ec9d ("sctp: do not check port in sctp_inet6_cmp_addr")

      net: systemport: Correclty disambiguate driver instances · 1f3ccc3c
      Florian Fainelli authored 
      While adding the DSA notifier, we will be sending DSA notifications with
info->master that is going to point to a particular net_device instance.

Our logic in bcm_sysport_map_queues() correctly disambiguates net_device
instances that are not covered by our own driver, but it will not make
sure that info->master points to a particular driver instance that we
are interested in. In a system where e.g: two or more SYSTEMPORT
instances are registered, this would lead in programming two or more
times the queue mapping, completely messing with the logic which does
the queue/port allocation and tracking.

Fix this by looking at the notifier_block pointer which is unique per
instance and allows us to go back to our driver private structure, and
in turn to the backing net_device instance.

To install in_netns.sh without being added to the main run_kselftest.sh
script use the TEST_GEN_PROGS_EXTENDED variable.

      tcp: ignore Fast Open on repair mode · 16ae6aa1
      Yuchung Cheng authored 
      The TCP repair sequence of operation is to first set the socket in
repair mode, then inject the TCP stats into the socket with repair
socket options, then call connect() to re-activate the socket. The
connect syscall simply returns and set state to ESTABLISHED
mode. As a result Fast Open is meaningless for TCP repair.

However allowing sendto() system call with MSG_FASTOPEN flag half-way
during the repair operation could unexpectedly cause data to be
sent, before the operation finishes changing the internal TCP stats
(e.g. MSS).  This in turn triggers TCP warnings on inconsistent
packet accounting.

The fix is to simply disallow Fast Open operation once the socket
is in the repair mode.

      Merge branch 'mvpp2-fixes' · cc2180a5
      David S. Miller authored 
      Maxime Chevallier says:

====================
net: mvpp2: Fix hangs when starting some interfaces on 7k/8k

Armada 7K / 8K clock management has recently been reworked, see :

commit c7e92def ("clk: mvebu: cp110: Fix clock tree representation")

I have been experiencing overall system hangs on MacchiatoBin when starting
the eth1 interface since then. It turns out some clocks dependencies were
missing in the PPv2 and xmdio driver, the clock rework made this visible.

This is the V2 series, that adds support for the missing 'MG Core clock' in
mvpp2, and fixes an issue with the error path for the axi_clk.

Thanks to Gregory Clement for finding the root cause of this bug.

V2 : Remove all DT patches from this series, they will be merged through
     the mvebu tree.

      net: mvpp2: Fix clock resource by adding missing mg_core_clk · 9af771ce
      Maxime Chevallier authored 
      Marvell's PPv2.2 IP needs an additional clock named "MG Core clock".
This is required on Armada 7K and 8K.

This commit adds the required clock in mvpp2, making sure it's only
used on PPv2.2.

      Maxime Chevallier authored 
      When clk_prepare_enable fails for the axi_clk, the mg_clk isn't properly
cleaned up. Add another jump label to handle that case, and make sure we
jump to it in the later error cases.

      nfp: don't depend on eth_tbl being available · c55ca688
      Jakub Kicinski authored 
      For very very old generation of the management FW Ethernet port
information table may theoretically not be available.  This in
turn will cause the nfp_port structures to not be allocated.

Make sure we don't crash the kernel when there is no eth_tbl:

RIP: 0010:nfp_net_pci_probe+0xf2/0xb40 [nfp]

Call Trace:

Found while working with broken/development version of management FW.
