+Subject: audit: fix undefined behavior in bit shift for AUDIT_BIT
+
+From: Gaosheng Cui <cuigaosheng1@huawei.com>
+
+[ Upstream commit 986d93f55bdeab1cac858d1e47b41fac10b2d7f6 ]
+
+Shifting signed 32-bit value by 31 bits is undefined, so changing
+significant bit to unsigned. The UBSAN warning calltrace like below:
+
+UBSAN: shift-out-of-bounds in kernel/auditfilter.c:179:23
+left shift of 1 by 31 places cannot be represented in type 'int'

+Subject: MIPS: pic32: treat port as signed integer
+
+From: Jason A. Donenfeld <Jason@zx2c4.com>
+
+[ Upstream commit 648060902aa302331b5d6e4f26d8ee0761d239ab ]
+
+get_port_from_cmdline() returns an int, yet is assigned to a char, which
+is wrong in its own right, but also, with char becoming unsigned, this
+poses problems, because -1 is used as an error value. Further
+complicating things, fw_init_early_console() is only ever called with a
+-1 argument. Fix this up by removing the unused argument from
+fw_init_early_console() and treating port as a proper signed integer.

+Subject: spi: stm32: fix stm32_spi_prepare_mbr() that halves spi clk for every
+ run
+
+From: Sean Nyekjaer <sean@geanix.com>
+
+[ Upstream commit 62aa1a344b0904549f6de7af958e8a1136fd5228 ]
+
+When this driver is used with a driver that uses preallocated spi_transfer
+structs. The speed_hz is halved by every run. This results in:
+
+spi_stm32 44004000.spi: SPI transfer setup failed
+ads7846 spi0.0: SPI transfer failed: -22
+
+Example when running with DIV_ROUND_UP():
+- First run; speed_hz = 1000000, spi->clk_rate 125000000
+ div 125 -> mbrdiv = 7, cur_speed = 976562
+- Second run; speed_hz = 976562
+ div 128,00007 (roundup to 129) -> mbrdiv = 8, cur_speed = 488281
+- Third run; speed_hz = 488281
+ div 256,000131072067109 (roundup to 257) and then -EINVAL is returned.
+
+Use DIV_ROUND_CLOSEST to allow to round down and allow us to keep the
+set speed.

+Subject: wifi: mac80211: Fix ack frame idr leak when mesh has no route
+
+From: Nicolas Cavallari <nicolas.cavallari@green-communications.fr>
+
+[ Upstream commit 39e7b5de9853bd92ddbfa4b14165babacd7da0ba ]
+
+When trying to transmit an data frame with tx_status to a destination
+that have no route in the mesh, then it is dropped without recrediting
+the ack_status_frames idr.
+
+Once it is exhausted, wpa_supplicant starts failing to do SAE with
+NL80211_CMD_FRAME and logs "nl80211: Frame command failed".
+
+Use ieee80211_free_txskb() instead of kfree_skb() to fix it.

+Subject: wifi: mac80211_hwsim: fix debugfs attribute ps with rc table support
+
+From: Jonas Jelonek <jelonek.jonas@gmail.com>
+
+[ Upstream commit 69188df5f6e4cecc6b76b958979ba363cd5240e8 ]
+
+Fixes a warning that occurs when rc table support is enabled
+(IEEE80211_HW_SUPPORTS_RC_TABLE) in mac80211_hwsim and the PS mode
+is changed via the exported debugfs attribute.
+
+When the PS mode is changed, a packet is broadcasted via
+hwsim_send_nullfunc by creating and transmitting a plain skb with only
+header initialized. The ieee80211 rate array in the control buffer is
+zero-initialized. When ratetbl support is enabled, ieee80211_get_tx_rates
+is called for the skb with sta parameter set to NULL and thus no
+ratetbl can be used. The final rate array then looks like
+[-1,0; 0,0; 0,0; 0,0] which causes the warning in ieee80211_get_tx_rate.
+
+The issue is fixed by setting the count of the first rate with idx '0'
+to 1 and hence ieee80211_get_tx_rates won't overwrite it with idx '-1'.
