+Subject: bnxt_en: Restore PTP tx_avail count in case of skb_pad() error
+
+From: Pavan Chebbi <pavan.chebbi@broadcom.com>
+
+[ Upstream commit 1e7962114c10957fe4d10a15eb714578a394e90b ]
+
+The current code only restores PTP tx_avail count when we get DMA
+mapping errors.  Fix it so that the PTP tx_avail count will be
+restored for both DMA mapping errors and skb_pad() errors.
+Otherwise PTP TX timestamp will not be available after a PTP
+packet hits the skb_pad() error.

+Subject: cipso: fix total option length computation
+
+From: Ondrej Mosnacek <omosnace@redhat.com>
+
+[ Upstream commit 9f36169912331fa035d7b73a91252d7c2512eb1a ]
+
+As evident from the definition of ip_options_get(), the IP option
+IPOPT_END is used to pad the IP option data array, not IPOPT_NOP. Yet
+the loop that walks the IP options to determine the total IP options
+length in cipso_v4_delopt() doesn't take IPOPT_END into account.
+
+Fix it by recognizing the IPOPT_END value as the end of actual options.

+
+From: Christian Marangi <ansuelsmth@gmail.com>
+
+[ Upstream commit ce5cdd3b05216b704a704f466fb4c2dff3778caf ]
+
+It was discovered that some device have CBR address set to 0 causing
+kernel panic when arch_sync_dma_for_cpu_all is called.
+
+This was notice in situation where the system is booted from TP1 and
+BMIPS_GET_CBR() returns 0 instead of a valid address and
+!!(read_c0_brcm_cmt_local() & (1 << 31)); not failing.
+
+The current check whether RAC flush should be disabled or not are not
+enough hence lets check if CBR is a valid address or not.

+[ Upstream commit ae9daffd9028f2500c9ac1517e46d4f2b57efb80 ]
+
+read_config_dword() contains strange condition checking ret for a
+number of values. The ret variable, however, is always zero because
+config_access() never returns anything else. Thus, the retry is always
+taken until number of tries is exceeded.
+
+The code looks like it wants to check *val instead of ret to see if the
+read gave an error response.

+Subject: net: lan743x: disable WOL upon resume to restore full data path
+ operation
+
+From: Raju Lakkaraju <Raju.Lakkaraju@microchip.com>
+
+[ Upstream commit 7725363936a88351b71495774c1e0e852ae4cdca ]
+
+When Wake-on-LAN (WoL) is active and the system is in suspend mode, triggering
+a system event can wake the system from sleep, which may block the data path.
+To restore normal data path functionality after waking, disable all wake-up
+events. Furthermore, clear all Write 1 to Clear (W1C) status bits by writing
+1's to them.

+
+A reproducer is available in the syzbot bug.
+
+When a request to add multiple actions with the same index is sent, the

+rtnl_lock, and causes tasks to hang.

+Return -EAGAIN to prevent infinite looping, while keeping documented
+behavior.

+Subject: net/sched: act_api: rely on rcu in tcf_idr_check_alloc
+
+From: Pedro Tammela <pctammela@mojatatu.com>
+
+[ Upstream commit 4b55e86736d5b492cf689125da2600f59c7d2c39 ]
+
+Instead of relying only on the idrinfo->lock mutex for
+bind/alloc logic, rely on a combination of rcu + mutex + atomics
+to better scale the case where multiple rtnl-less filters are
+binding to the same action object.
+
+Action binding happens when an action index is specified explicitly and
+an action exists which such index exists. Example:
+  tc actions add action drop index 1
+  tc filter add ... matchall action drop index 1
+  tc filter add ... matchall action drop index 1
+  tc filter add ... matchall action drop index 1
+  tc filter ls ...
+     filter protocol all pref 49150 matchall chain 0 filter protocol all pref 49150 matchall chain 0 handle 0x1
+     not_in_hw
+           action order 1: gact action drop
+            random type none pass val 0
+            index 1 ref 4 bind 3
+
+   filter protocol all pref 49151 matchall chain 0 filter protocol all pref 49151 matchall chain 0 handle 0x1
+     not_in_hw
+           action order 1: gact action drop
+            random type none pass val 0
+            index 1 ref 4 bind 3
+
+   filter protocol all pref 49152 matchall chain 0 filter protocol all pref 49152 matchall chain 0 handle 0x1
+     not_in_hw
+           action order 1: gact action drop
+            random type none pass val 0
+            index 1 ref 4 bind 3
+
+When no index is specified, as before, grab the mutex and allocate
+in the idr the next available id. In this version, as opposed to before,
+it's simplified to store the -EBUSY pointer instead of the previous
+alloc + replace combination.
+
+When an index is specified, rely on rcu to find if there's an object in
+such index. If there's none, fallback to the above, serializing on the
+mutex and reserving the specified id. If there's one, it can be an -EBUSY
+pointer, in which case we just try again until it's an action, or an action.
+Given the rcu guarantees, the action found could be dead and therefore
+we need to bump the refcount if it's not 0, handling the case it's
+in fact 0.
+
+As bind and the action refcount are already atomics, these increments can
+happen without the mutex protection while many tcf_idr_check_alloc race
+to bind to the same action instance.
+
+In case binding encounters a parallel delete or add, it will return
+-EAGAIN in order to try again. Both filter and action apis already
+have the retry machinery in-place. In case it's an unlocked filter it
+retries under the rtnl lock.

+
+When destroying all sets, we are either in pernet exit phase or
+are executing a "destroy all sets command" from userspace. The latter
+was taken into account in ip_set_dereference() (nfnetlink mutex is held),

+rcu_dereference_protected() in ip_set_dereference().

+Subject: netrom: Fix a memory leak in nr_heartbeat_expiry()
+
+From: Gavrilov Ilia <Ilia.Gavrilov@infotecs.ru>
+
+[ Upstream commit 0b9130247f3b6a1122478471ff0e014ea96bb735 ]
+
+syzbot reported a memory leak in nr_create() [0].
+
+Commit 409db27e3a2e ("netrom: Fix use-after-free of a listening socket.")
+added sock_hold() to the nr_heartbeat_expiry() function, where
+a) a socket has a SOCK_DESTROY flag or
+b) a listening socket has a SOCK_DEAD flag.
+
+But in the case "a," when the SOCK_DESTROY flag is set, the file descriptor
+has already been closed and the nr_release() function has been called.
+So it makes no sense to hold the reference count because no one will
+call another nr_destroy_socket() and put it as in the case "b."
+
+nr_connect
+  nr_establish_data_link
+    nr_start_heartbeat
+
+nr_release
+  switch (nr->state)
+  case NR_STATE_3
+    nr->state = NR_STATE_2
+    sock_set_flag(sk, SOCK_DESTROY);
+
+                        nr_rx_frame
+                          nr_process_rx_frame
+                            switch (nr->state)
+                            case NR_STATE_2
+                              nr_state2_machine()
+                                nr_disconnect()
+                                  nr_sk(sk)->state = NR_STATE_0
+                                  sock_set_flag(sk, SOCK_DEAD)
+
+                        nr_heartbeat_expiry
+                          switch (nr->state)
+                          case NR_STATE_0
+                            if (sock_flag(sk, SOCK_DESTROY) ||
+                               (sk->sk_state == TCP_LISTEN
+                                 && sock_flag(sk, SOCK_DEAD)))
+                               sock_hold()  // ( !!! )
+                               nr_destroy_socket()
+
+To fix the memory leak, let's call sock_hold() only for a listening socket.

+Subject: sched: act_ct: add netns into the key of tcf_ct_flow_table
+
+From: Xin Long <lucien.xin@gmail.com>
+
+[ Upstream commit 88c67aeb14070bab61d3dd8be96c8b42ebcaf53a ]
+
+zones_ht is a global hashtable for flow_table with zone as key. However,
+it does not consider netns when getting a flow_table from zones_ht in
+tcf_ct_init(), and it means an act_ct action in netns A may get a
+flow_table that belongs to netns B if it has the same zone value.
+
+In Shuang's test with the TOPO:
+
+  tcf2_c <---> tcf2_sw1 <---> tcf2_sw2 <---> tcf2_s
+
+tcf2_sw1 and tcf2_sw2 saw the same flow and used the same flow table,
+which caused their ct entries entering unexpected states and the
+TCP connection not able to end normally.
+
+This patch fixes the issue simply by adding netns into the key of
+tcf_ct_flow_table so that an act_ct action gets a flow_table that
+belongs to its own netns in tcf_ct_init().
+
+Note that for easy coding we don't use tcf_ct_flow_table.nf_ft.net,
+as the ct_ft is initialized after inserting it to the hashtable in
+tcf_ct_flow_table_get() and also it requires to implement several
+functions in rhashtable_params including hashfn, obj_hashfn and
+obj_cmpfn.

+
+[ Upstream commit 3572bd5689b0812b161b40279e39ca5b66d73e88 ]
+
+The kprobes and synth event generation test modules add events and lock
+(get a reference) those event file reference in module init function,
+and unlock and delete it in module exit function. This is because those
+are designed for playing as modules.
+
+If we make those modules as built-in, those events are left locked in the
+kernel, and never be removed. This causes kprobe event self-test failure
+as below.

+Subject: virtio_net: checksum offloading handling fix
+
+From: Heng Qi <hengqi@linux.alibaba.com>
+
+[ Upstream commit 604141c036e1b636e2a71cf6e1aa09d1e45f40c2 ]
+
+In virtio spec 0.95, VIRTIO_NET_F_GUEST_CSUM was designed to handle
+partially checksummed packets, and the validation of fully checksummed
+packets by the device is independent of VIRTIO_NET_F_GUEST_CSUM
+negotiation. However, the specification erroneously stated:
+
+  "If VIRTIO_NET_F_GUEST_CSUM is not negotiated, the device MUST set flags
+   to zero and SHOULD supply a fully checksummed packet to the driver."
+
+This statement is inaccurate because even without VIRTIO_NET_F_GUEST_CSUM
+negotiation, the device can still set the VIRTIO_NET_HDR_F_DATA_VALID flag.
+Essentially, the device can facilitate the validation of these packets'
+checksums - a process known as RX checksum offloading - removing the need
+for the driver to do so.
+
+This scenario is currently not implemented in the driver and requires
+correction. The necessary specification correction[1] has been made and
+approved in the virtio TC vote.
