+Subject: 9p/xen : Fix use after free bug in xen_9pfs_front_remove due to race
+ condition
+
+From: Zheng Wang <zyytlz.wz@163.com>
+
+[ Upstream commit ea4f1009408efb4989a0f139b70fb338e7f687d0 ]
+
+In xen_9pfs_front_probe, it calls xen_9pfs_front_alloc_dataring
+to init priv->rings and bound &ring->work with p9_xen_response.
+
+When it calls xen_9pfs_front_event_handler to handle IRQ requests,
+it will finally call schedule_work to start the work.
+
+When we call xen_9pfs_front_remove to remove the driver, there
+may be a sequence as follows:
+
+Fix it by finishing the work before cleanup in xen_9pfs_front_free.
+
+Note that, this bug is found by static analysis, which might be
+false positive.

+
+[ Upstream commit e8b74453555872851bdd7ea43a7c0ec39659834f ]
+
+For quite some time we were chasing a bug which looked like a sudden
+permanent failure of networking and mmc on some of our devices.
+The bug was very sensitive to any software changes and even more to
+any kernel debug options.
+
+Finally we got a setup where the problem was reproducible with
+CONFIG_DMA_API_DEBUG=y and it revealed the issue with the rx dma:

+
+Lars was fast to find an explanation: according to the datasheet
+bit 2 of the rx buffer descriptor entry has a different meaning in the
+extended mode:
+ Address [2] of beginning of buffer, or
+ in extended buffer descriptor mode (DMA configuration register [28] = 1),
+ indicates a valid timestamp in the buffer descriptor entry.
+
+The macb driver didn't mask this bit while getting an address and it
+eventually caused a memory corruption and a dma failure.
+
+The problem is resolved by explicitly clearing the problematic bit
+if hw timestamping is used.

+Subject: qlcnic: check pci_reset_function result
+
+From: Denis Plotnikov <den-plotnikov@yandex-team.ru>
+
+[ Upstream commit 7573099e10ca69c3be33995c1fcd0d241226816d ]
+
+Static code analyzer complains to unchecked return value.
+The result of pci_reset_function() is unchecked.
+Despite, the issue is on the FLR supported code path and in that
+case reset can be done with pcie_flr(), the patch uses less invasive
+approach by adding the result check of pci_reset_function().
+
+Found by Linux Verification Center (linuxtesting.org) with SVACE.

+Subject: sctp: fix a potential overflow in sctp_ifwdtsn_skip
+
+From: Xin Long <lucien.xin@gmail.com>
+
+[ Upstream commit 32832a2caf82663870126c5186cf8f86c8b2a649 ]
+
+Currently, when traversing ifwdtsn skips with _sctp_walk_ifwdtsn, it only
+checks the pos against the end of the chunk. However, the data left for
+the last pos may be < sizeof(struct sctp_ifwdtsn_skip), and dereference
+it as struct sctp_ifwdtsn_skip may cause coverflow.
+
+This patch fixes it by checking the pos against "the end of the chunk -
+sizeof(struct sctp_ifwdtsn_skip)" in sctp_ifwdtsn_skip, similar to
+sctp_fwdtsn_skip.

+Subject: udp6: fix potential access to stale information
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Eric Dumazet <edumazet@google.com>
+
+[ Upstream commit 1c5950fc6fe996235f1d18539b9c6b64b597f50f ]
+
+lena wang reported an issue caused by udpv6_sendmsg()
+mangling msg->msg_name and msg->msg_namelen, which
+are later read from ____sys_sendmsg() :
+
+ /*
+ * If this is sendmmsg() and sending to current destination address was
+ * successful, remember it.
+ */
+ if (used_address && err >= 0) {
+ used_address->name_len = msg_sys->msg_namelen;
+ if (msg_sys->msg_name)
+ memcpy(&used_address->name, msg_sys->msg_name,
+ used_address->name_len);
+ }
+
+udpv6_sendmsg() wants to pretend the remote address family
+is AF_INET in order to call udp_sendmsg().
+
+A fix would be to modify the address in-place, instead
+of using a local variable, but this could have other side effects.
+
+Instead, restore initial values before we return from udpv6_sendmsg().

+Subject: verify_pefile: relax wrapper length check
+
+From: Robbie Harwood <rharwood@redhat.com>
+
+[ Upstream commit 4fc5c74dde69a7eda172514aaeb5a7df3600adb3 ]
+
+The PE Format Specification (section "The Attribute Certificate Table
+(Image Only)") states that `dwLength` is to be rounded up to 8-byte
+alignment when used for traversal. Therefore, the field is not required
+to be an 8-byte multiple in the first place.
+
+Accordingly, pesign has not performed this alignment since version
+0.110. This causes kexec failure on pesign'd binaries with "PEFILE:
+Signature wrapper len wrong". Update the comment and relax the check.
