+[ Upstream commit 7b75c4703609a3ebaf67271813521bc0281e1ec1 ]
+
+Add the IRQCHIP_SKIP_SET_WAKE flag since there are no special IRQ Wake

+Subject: icmp: guard against too small mtu
+
+From: Eric Dumazet <edumazet@google.com>
+
+[ Upstream commit 7d63b67125382ff0ffdfca434acbc94a38bd092b ]
+
+syzbot was able to trigger a panic [1] in icmp_glue_bits(), or
+more exactly in skb_copy_and_csum_bits()
+
+There is no repro yet, but I think the issue is that syzbot
+manages to lower device mtu to a small value, fooling __icmp_send()
+
+__icmp_send() must make sure there is enough room for the
+packet to include at least the headers.
+
+We might in the future refactor skb_copy_and_csum_bits() and its
+callers to no longer crash when something bad happens.

+It is because icmp6hdr does not in skb linear region under the scenario
+of SOCK_RAW socket. Access icmp6_hdr(skb)->icmp6_type directly will

+
+Use a local variable icmp6_type to carry the correct value in different

+Subject: net: don't let netpoll invoke NAPI if in xmit context
+
+From: Jakub Kicinski <kuba@kernel.org>
+
+[ Upstream commit 275b471e3d2daf1472ae8fa70dc1b50c9e0b9e75 ]
+
+Commit 0db3dc73f7a3 ("[NETPOLL]: tx lock deadlock fix") narrowed
+down the region under netif_tx_trylock() inside netpoll_send_skb().
+(At that point in time netif_tx_trylock() would lock all queues of
+the device.) Taking the tx lock was problematic because driver's
+cleanup method may take the same lock. So the change made us hold
+the xmit lock only around xmit, and expected the driver to take
+care of locking within ->ndo_poll_controller().
+
+Unfortunately this only works if netpoll isn't itself called with
+the xmit lock already held. Netpoll code is careful and uses
+trylock(). The drivers, however, may be using plain lock().
+Printing while holding the xmit lock is going to result in rare
+deadlocks.
+
+Luckily we record the xmit lock owners, so we can scan all the queues,
+the same way we scan NAPI owners. If any of the xmit locks is held
+by the local CPU we better not attempt any polling.
+
+It would be nice if we could narrow down the check to only the NAPIs
+and the queue we're trying to use. I don't see a way to do that now.

+Subject: sctp: check send stream number after wait_for_sndbuf
+
+From: Xin Long <lucien.xin@gmail.com>
+
+[ Upstream commit 2584024b23552c00d95b50255e47bd18d306d31a ]
+
+This patch fixes a corner case where the asoc out stream count may change
+after wait_for_sndbuf.
+
+When the main thread in the client starts a connection, if its out stream
+count is set to N while the in stream count in the server is set to N - 2,
+another thread in the client keeps sending the msgs with stream number
+N - 1, and waits for sndbuf before processing INIT_ACK.
+
+However, after processing INIT_ACK, the out stream count in the client is
+shrunk to N - 2, the same to the in stream count in the server. The crash
+occurs when the thread waiting for sndbuf is awake and sends the msg in a
+non-existing stream(N - 1), the call trace is as below:
+
+ KASAN: null-ptr-deref in range [0x0000000000000038-0x000000000000003f]

+
+The fix is to add an unlikely check for the send stream number after the
+thread wakes up from the wait_for_sndbuf.

+Subject: sunrpc: only free unix grouplist after RCU settles
+
+From: Jeff Layton <jlayton@kernel.org>
+
+[ Upstream commit 5085e41f9e83a1bec51da1f20b54f2ec3a13a3fe ]
+
+While the unix_gid object is rcu-freed, the group_info list that it
+contains is not. Ensure that we only put the group list reference once
+we are really freeing the unix_gid object.
