+
+From: Wang Hai <wanghai38@huawei.com>
+
+commit 776c75010803849c1cc4f11031a2b3960ab05202 upstream.
+
+I got a null-ptr-deref report:
+
+KASAN: null-ptr-deref in range [0x0000000000000090-0x0000000000000097]

+If devm_regulator_get() in ahci_platform_get_resources() fails,

+
+commit 962399bb7fbf ("ata: libahci_platform: Fix regulator_get_optional()
+misuse") replaces devm_regulator_get_optional() with devm_regulator_get(),
+but PHY regulator omits to delete "hpriv->phy_regulator = NULL;" like AHCI.
+Delete it like AHCI regulator to fix this bug.

+From: Colin Ian King <colin.king@canonical.com>
+
+commit 2133c4fc8e1348dcb752f267a143fe2254613b34 upstream.
+
+The initialization of pointer dev dereferences pointer edp before
+edp is null checked, so there is a potential null pointer deference
+issue. Fix this by only dereferencing edp after edp has been null
+checked.

+Subject: ionic: don't remove netdev->dev_addr when syncing uc list
+
+From: Shannon Nelson <snelson@pensando.io>
+
+commit 5c976a56570f29aaf4a2f9a1bf99789c252183c9 upstream.
+
+Bridging, and possibly other upper stack gizmos, adds the
+lower device's netdev->dev_addr to its own uc list, and
+then requests it be deleted when the upper bridge device is
+removed. This delete request also happens with the bridging
+vlan_filtering is enabled and then disabled.
+
+Bonding has a similar behavior with the uc list, but since it
+also uses set_mac to manage netdev->dev_addr, it doesn't have
+the same the failure case.
+
+Because we store our netdev->dev_addr in our uc list, we need
+to ignore the delete request from dev_uc_sync so as to not
+lose the address and all hope of communicating. Note that
+ndo_set_mac_address is expressly changing netdev->dev_addr,
+so no limitation is set there.

+Subject: mlxsw: thermal: Fix out-of-bounds memory accesses
+
+From: Ido Schimmel <idosch@nvidia.com>
+
+commit 332fdf951df8b870e3da86b122ae304e2aabe88c upstream.
+
+Currently, mlxsw allows cooling states to be set above the maximum
+cooling state supported by the driver:
+
+ # cat /sys/class/thermal/thermal_zone2/cdev0/type
+ mlxsw_fan
+ # cat /sys/class/thermal/thermal_zone2/cdev0/max_state
+ 10
+ # echo 18 > /sys/class/thermal/thermal_zone2/cdev0/cur_state
+ # echo $?
+ 0
+
+This results in out-of-bounds memory accesses when thermal state
+transition statistics are enabled (CONFIG_THERMAL_STATISTICS=y), as the
+transition table is accessed with a too large index (state) [1].
+
+According to the thermal maintainer, it is the responsibility of the
+driver to reject such operations [2].
+
+Therefore, return an error when the state to be set exceeds the maximum
+cooling state supported by the driver.
+
+To avoid dead code, as suggested by the thermal maintainer [3],
+partially revert commit a421ce088ac8 ("mlxsw: core: Extend cooling
+device with cooling levels") that tried to interpret these invalid
+cooling states (above the maximum) in a special way. The cooling levels
+array is not removed in order to prevent the fans going below 20% PWM,
+which would cause them to get stuck at 0% PWM.

+Subject: mqprio: Correct stats in mqprio_dump_class_stats().
+
+From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
+
+commit 14132690860e4d06aa3e1c4d7d8e9866ba7756dd upstream.
+
+Introduction of lockless subqueues broke the class statistics.
+Before the change stats were accumulated in `bstats' and `qstats'
+on the stack which was then copied to struct gnet_dump.
+
+After the change the `bstats' and `qstats' are initialized to 0
+and never updated, yet still fed to gnet_dump. The code updates
+the global qdisc->cpu_bstats and qdisc->cpu_qstats instead,
+clobbering them. Most likely a copy-paste error from the code in
+mqprio_dump().
+
+__gnet_stats_copy_basic() and __gnet_stats_copy_queue() accumulate
+the values for per-CPU case but for global stats they overwrite
+the value, so only stats from the last loop iteration / tc end up
+in sch->[bq]stats.
+
+Use the on-stack [bq]stats variables again and add the stats manually
+in the global case.

+
+From: Ziyang Xuan <william.xuanziyang@huawei.com>
+
+commit 0911ab31896f0e908540746414a77dd63912748d upstream.
+
+When nfc proto id is using, nfc_proto_register() return -EBUSY error
+code, but forgot to unregister proto. Fix it by adding proto_unregister()
+in the error handling case.

+Subject: platform/mellanox: mlxreg-io: Fix argument base in kstrtou32() call
+
+From: Vadim Pasternak <vadimp@nvidia.com>
+
+commit 9b024201693e397441668cca0d2df7055fe572eb upstream.
+
+Change kstrtou32() argument 'base' to be zero instead of 'len'.
+It works by chance for setting one bit value, but it is not supposed to
+work in case value passed to mlxreg_io_attr_store() is greater than 1.
+
+It works for example, for:
+echo 1 > /sys/devices/platform/mlxplat/mlxreg-io/hwmon/.../jtag_enable
+But it will fail for:
+echo n > /sys/devices/platform/mlxplat/mlxreg-io/hwmon/.../jtag_enable,
+where n > 1.
+
+The flow for input buffer conversion is as below:
+_kstrtoull(const char *s, unsigned int base, unsigned long long *res)
+calls:
+rv = _parse_integer(s, base, &_res);
+
+For the second case, where n > 1:
+- _parse_integer() converts 's' to 'val'.
+ For n=2, 'len' is set to 2 (string buffer is 0x32 0x0a), for n=3
+ 'len' is set to 3 (string buffer 0x33 0x0a), etcetera.
+- 'base' is equal or greater then '2' (length of input buffer).
+
+As a result, _parse_integer() exits with result zero (rv):
+ rv = 0;
+ while (1) {
+ ...
+ if (val >= base)-> (2 >= 2)
+ break;
+ ...
+ rv++;
+ ...
+ }
+
+And _kstrtoull() in their turn will fail:
+ if (rv == 0)
+ return -EINVAL;
