+Subject: bonding: send learning packets for vlans on slave
+
+From: Debabrata Banerjee <dbanerje@akamai.com>
+
+[ Upstream commit 21706ee8a47d3ede7fdae0be6d7c0a0e31a83229 ]
+
+There was a regression at some point from the intended functionality of
+commit f60c3704e87d ("bonding: Fix alb mode to only use first level
+vlans.")
+
+Given the return value vlan_get_encap_level() we need to store the nest
+level of the bond device, and then compare the vlan's encap level to
+this. Without this, this check always fails and learning packets are
+never sent.
+
+In addition, this same commit caused a regression in the behavior of
+balance_alb, which requires learning packets be sent for all interfaces
+using the slave's mac in order to load balance properly. For vlan's
+that have not set a user mac, we can send after checking one bit.
+Otherwise we need send the set mac, albeit defeating rx load balancing
+for that vlan.

+Subject: bridge: check iface upper dev when setting master via ioctl
+
+From: Hangbin Liu <liuhangbin@gmail.com>
+
+[ Upstream commit e8238fc2bd7b4c3c7554fa2df067e796610212fc ]
+
+When we set a bond slave's master to bridge via ioctl, we only check
+the IFF_BRIDGE_PORT flag. Although we will find the slave's real master
+at netdev_master_upper_dev_link() later, it already does some settings
+and allocates some resources. It would be better to return as early
+as possible.
+
+v1 -> v2:
+use netdev_master_upper_dev_get() instead of netdev_has_any_upper_dev()
+to check if we have a master, because not all upper devs are masters,
+e.g. vlan device.

+[ Upstream commit 1b97013bfb11d66f041de691de6f0fec748ce016 ]
+
+Fix more memory leaks in ip_cmsg_send() callers. Part of them were fixed
+earlier in 919483096bfe.
+
+* udp_sendmsg one was there since the beginning when linux sources were

+* ping_v4_sendmsg one was copy/pasted in c319b4d76b9e.
+
+Whenever return happens in udp_sendmsg() or ping_v4_sendmsg() IP options
+have to be freed if they were allocated previously.
+
+Add label so that future callers (if any) can use it instead of kfree()
+before return that is easy to forget.

+
+From: Rob Taglang <rob@taglang.io>
+
+[ Upstream commit 14224923c3600bae2ac4dcae3bf0c3d4dc2812be ]
+
+Currently, skb->len and skb->data_len are set to the page size, not
+the packet size. This causes the frame check sequence to not be
+located at the "end" of the packet resulting in ethernet frame check
+errors. The driver does work currently, but stricter kernel facing
+networking solutions like OpenVSwitch will drop these packets as
+invalid.
+
+These changes set the packet size correctly so that these errors no
+longer occur. The length does not include the frame check sequence, so
+that subtraction was removed.
+
+Tested on Oracle/SUN Multithreaded 10-Gigabit Ethernet Network
+Controller [108e:abcd] and validated in wireshark.

+
+From: Grygorii Strashko <grygorii.strashko@ti.com>
+
+[ Upstream commit 5e5add172ea81152d518b161ec5706503ad3d799 ]
+
+In dual_mac mode packets arrived on one port should not be forwarded by
+switch hw to another port. Only Linux Host can forward packets between
+ports. The below test case (reported in [1]) shows that packet arrived on
+one port can be leaked to anoter (reproducible with dual port evms):
+ - connect port 1 (eth0) to linux Host 0 and run tcpdump or Wireshark
+ - connect port 2 (eth1) to linux Host 1 with vlan 1 configured
+ - ping <IPx> from Host 1 through vlan 1 interface.
+ARP packets will be seen on Host 0.
+
+Issue happens because dual_mac mode is implemnted using two vlans: 1 (Port
+1+Port 0) and 2 (Port 2+Port 0), so there are vlan records created for for
+each vlan. By default, the ALE will find valid vlan record in its table
+when vlan 1 tagged packet arrived on Port 2 and so forwards packet to all
+ports which are vlan 1 members (like Port.
+
+To avoid such behaviorr the ALE VLAN ID Ingress Check need to be enabled
+for each external CPSW port (ALE_PORTCTLn.VID_INGRESS_CHECK) so ALE will
+drop ingress packets if Rx port is not VLAN member.

+From: Moshe Shemesh <moshe@mellanox.com>
+
+[ Upstream commit 6ad4e91c6d796b38a7f0e724db1de28eeb122bad ]
+
+Add check of coalescing parameters received through ethtool are within
+range of values supported by the HW.
+Driver gets the coalescing rx/tx-usecs and rx/tx-frames as set by the
+users through ethtool. The ethtool support up to 32 bit value for each.
+However, mlx4 modify cq limits the coalescing time parameter and
+coalescing frames parameters to 16 bits.
+Return out of range error if user tries to set these parameters to
+higher values.
+Change type of sample-interval and adaptive_rx_coal parameters in mlx4
+driver to u32 as the ethtool holds them as u32 and these parameters are
+not limited due to mlx4 HW.

+Subject: net: support compat 64-bit time in {s,g}etsockopt
+
+From: Lance Richardson <lance.richardson.net@gmail.com>
+
+[ Upstream commit 988bf7243e03ef69238381594e0334a79cef74a6 ]
+
+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.
+
+Results before patch:

+
+From: Eric Dumazet <edumazet@google.com>
+
+[ Upstream commit 7df40c2673a1307c3260aab6f9d4b9bf97ca8fd7 ]
+
+Normally, a socket can not be freed/reused unless all its TX packets
+left qdisc and were TX-completed. However connect(AF_UNSPEC) allows
+this to happen.
+
+With commit fc59d5bdf1e3 ("pkt_sched: fq: clear time_next_packet for
+reused flows") we cleared f->time_next_packet but took no special
+action if the flow was still in the throttled rb-tree.
+
+Since f->time_next_packet is the key used in the rb-tree searches,
+blindly clearing it might break rb-tree integrity. We need to make
+sure the flow is no longer in the rb-tree to avoid this problem.

+Subject: openvswitch: Don't swap table in nlattr_set() after OVS_ATTR_NESTED is found
+
+From: Stefano Brivio <sbrivio@redhat.com>
+
+[ Upstream commit 72f17baf2352ded6a1d3f4bb2d15da8c678cd2cb ]
+
+If an OVS_ATTR_NESTED attribute type is found while walking
+through netlink attributes, we call nlattr_set() recursively
+passing the length table for the following nested attributes, if
+different from the current one.
+
+However, once we're done with those sub-nested attributes, we
+should continue walking through attributes using the current
+table, instead of using the one related to the sub-nested
+attributes.
+
+For example, given this sequence:
+
+1 OVS_KEY_ATTR_PRIORITY
+2 OVS_KEY_ATTR_TUNNEL
+3 OVS_TUNNEL_KEY_ATTR_ID
+4 OVS_TUNNEL_KEY_ATTR_IPV4_SRC
+5 OVS_TUNNEL_KEY_ATTR_IPV4_DST
+6 OVS_TUNNEL_KEY_ATTR_TTL
+7 OVS_TUNNEL_KEY_ATTR_TP_SRC
+8 OVS_TUNNEL_KEY_ATTR_TP_DST
+9 OVS_KEY_ATTR_IN_PORT
+10 OVS_KEY_ATTR_SKB_MARK
+11 OVS_KEY_ATTR_MPLS
+
+we switch to the 'ovs_tunnel_key_lens' table on attribute #3,
+and we don't switch back to 'ovs_key_lens' while setting
+attributes #9 to #11 in the sequence. As OVS_KEY_ATTR_MPLS
+evaluates to 21, and the array size of 'ovs_tunnel_key_lens' is
+15, we also get this kind of KASan splat while accessing the
+wrong table:

+
+[ Upstream commit 5697db4a696c41601a1d15c1922150b4dbf5726c ]
+
+The USB_DEVICE_INTERFACE_NUMBER matching macro assumes that
+the { vendorid, productid, interfacenumber } set uniquely
+identifies one specific function. This has proven to fail
+for some configurable devices. One example is the Quectel
+EM06/EP06 where the same interface number can be either
+QMI or MBIM, without the device ID changing either.
+
+Fix by requiring the vendor-specific class for interface number
+based matching. Functions of other classes can and should use
+class based matching instead.

+Subject: r8169: fix powering up RTL8168h
+
+From: Heiner Kallweit <hkallweit1@gmail.com>
+
+[ Upstream commit 3148dedfe79e422f448a10250d3e2cdf8b7ee617 ]
+
+Since commit a92a08499b1f "r8169: improve runtime pm in general and
+suspend unused ports" interfaces w/o link are runtime-suspended after
+10s. On systems where drivers take longer to load this can lead to the
+situation that the interface is runtime-suspended already when it's
+initially brought up.
+This shouldn't be a problem because rtl_open() resumes MAC/PHY.
+However with at least one chip version the interface doesn't properly
+come up, as reported here:
+https://bugzilla.kernel.org/show_bug.cgi?id=199549
+
+The vendor driver uses a delay to give certain chip versions some
+time to resume before starting the PHY configuration. So let's do
+the same. I don't know which chip versions may be affected,
+therefore apply this delay always.
+
+This patch was reported to fix the issue for RTL8168h.
+I was able to reproduce the issue on an Asus H310I-Plus which also
+uses a RTL8168h. Also in my case the patch fixed the issue.

+Subject: sctp: delay the authentication for the duplicated cookie-echo chunk
+
+From: Xin Long <lucien.xin@gmail.com>
+
+[ Upstream commit 59d8d4434f429b4fa8a346fd889058bda427a837 ]
+
+Now sctp only delays the authentication for the normal cookie-echo
+chunk by setting chunk->auth_chunk in sctp_endpoint_bh_rcv(). But
+for the duplicated one with auth, in sctp_assoc_bh_rcv(), it does
+authentication first based on the old asoc, which will definitely
+fail due to the different auth info in the old asoc.
+
+The duplicated cookie-echo chunk will create a new asoc with the
+auth info from this chunk, and the authentication should also be
+done with the new asoc's auth info for all of the collision 'A',
+'B' and 'D'. Otherwise, the duplicated cookie-echo chunk with auth
+will never pass the authentication and create the new connection.
+
+This issue exists since very beginning, and this fix is to make
+sctp_assoc_bh_rcv() follow the way sctp_endpoint_bh_rcv() does
+for the normal cookie-echo chunk to delay the authentication.
+
+While at it, remove the unused params from sctp_sf_authenticate()
+and define sctp_auth_chunk_verify() used for all the places that
+do the delayed authentication.
+
+v1->v2:
+ fix the typo in changelog as Marcelo noticed.

+Subject: sctp: fix the issue that the cookie-ack with auth can't get processed
+
+From: Xin Long <lucien.xin@gmail.com>
+
+[ Upstream commit ce402f044e4e432c296f90eaabb8dbe8f3624391 ]
+
+When auth is enabled for cookie-ack chunk, in sctp_inq_pop, sctp
+processes auth chunk first, then continues to the next chunk in
+this packet if chunk_end + chunk_hdr size < skb_tail_pointer().
+Otherwise, it will go to the next packet or discard this chunk.
+
+However, it missed the fact that cookie-ack chunk's size is equal
+to chunk_hdr size, which couldn't match that check, and thus this
+chunk would not get processed.
+
+This patch fixes it by changing the check to chunk_end + chunk_hdr
+size <= skb_tail_pointer().

+Subject: sctp: handle two v4 addrs comparison in sctp_inet6_cmp_addr
+
+From: Xin Long <lucien.xin@gmail.com>
+
+[ Upstream commit d625329b06e46bd20baf9ee40847d11982569204 ]
+
+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 1071ec9d453a ("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: 1071ec9d453a ("sctp: do not check port in sctp_inet6_cmp_addr")

+Subject: sctp: use the old asoc when making the cookie-ack chunk in dupcook_d
+
+From: Xin Long <lucien.xin@gmail.com>
+
+[ Upstream commit 46e16d4b956867013e0bbd7f2bad206f4aa55752 ]
+
+When processing a duplicate cookie-echo chunk, for case 'D', sctp will
+not process the param from this chunk. It means old asoc has nothing
+to be updated, and the new temp asoc doesn't have the complete info.
+
+So there's no reason to use the new asoc when creating the cookie-ack
+chunk. Otherwise, like when auth is enabled for cookie-ack, the chunk
+can not be set with auth, and it will definitely be dropped by peer.
+
+This issue is there since very beginning, and we fix it by using the
+old asoc instead.

+Subject: tcp: ignore Fast Open on repair mode
+
+From: Yuchung Cheng <ycheng@google.com>
+
+[ Upstream commit 16ae6aa1705299789f71fdea59bfb119c1fbd9c0 ]
+
+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.

+Subject: tcp_bbr: fix to zero idle_restart only upon S/ACKed data
+
+From: Neal Cardwell <ncardwell@google.com>
+
+[ Upstream commit e6e6a278b1eaffa19d42186bfacd1ffc15a50b3f ]
+
+Previously the bbr->idle_restart tracking was zeroing out the
+bbr->idle_restart bit upon ACKs that did not SACK or ACK anything,
+e.g. receiving incoming data or receiver window updates. In such
+situations BBR would forget that this was a restart-from-idle
+situation, and if the min_rtt had expired it would unnecessarily enter
+PROBE_RTT (even though we were actually restarting from idle but had
+merely forgotten that fact).
+
+The fix is simple: we need to remember we are restarting from idle
+until we receive a S/ACK for some data (a S/ACK for the first flight
+of data we send as we are restarting).
+
+This commit is a stable candidate for kernels back as far as 4.9.

+
+[ Upstream commit d89a2adb8bfe6f8949ff389acdb9fa298b6e8e12 ]
+
+tg3_free_consistent() calls dma_free_coherent() to free tp->hw_stats
+under spinlock and can trigger BUG_ON() in vunmap() because vunmap()
+may sleep. Fix it by removing the spinlock and relying on the
+TG3_FLAG_INIT_COMPLETE flag to prevent race conditions between
+tg3_get_stats64() and tg3_free_consistent(). TG3_FLAG_INIT_COMPLETE
+is always cleared under tp->lock before tg3_free_consistent()
+and therefore tg3_get_stats64() can safely access tp->hw_stats
+under tp->lock if TG3_FLAG_INIT_COMPLETE is set.
