[ Upstream commit 45ac774c ] When we try to transmit an skb with md_dst attached through wireguard we hit a null pointer dereference in wg_xmit() due to the use of dst_mtu() which calls into dst_blackhole_mtu() which in turn tries to dereference dst->dev. Since wireguard doesn't use md_dsts we should use skb_valid_dst(), which checks for DST_METADATA flag, and if it's set, then falls back to wireguard's device mtu. That gives us the best chance of transmitting the packet; otherwise if the blackhole netdev is used we'd get ETH_MIN_MTU.

[ Upstream commit b253a068 ] If an ACK (s)acks multiple skbs, we favor the information from the most recently sent skb by choosing the skb with the highest prior_delivered count. But in the interval between receiving ACKs, we send multiple skbs with the same prior_delivered, because the tp->delivered only changes when we receive an ACK. We used RACK's solution, copying tcp_rack_sent_after() as tcp_skb_sent_after() helper to determine "which packet was sent last?". Later, we will use tcp_skb_sent_after() instead in RACK.

[ Upstream commit 05d8af44 ] The current EOI handler for LEVEL triggered interrupts calls clk_enable(), register IO, clk_disable(). The clock manipulation requires locking which happens with IRQs disabled in clk_enable_lock(). Instead of turning the clock on and off all the time, enable the clock in case LEVEL interrupt is requested and keep the clock enabled until all LEVEL interrupts are freed. The LEVEL interrupts are an exception on this platform and seldom used, so this does not affect the common case. This simplifies the LEVEL interrupt handling considerably and also fixes the following splat found when using preempt-rt: ------------[ cut here ]------------ WARNING: CPU: 0 PID: 0 at kernel/locking/rtmutex.c:2040 __rt_mutex_trylock+0x37/0x62 Modules linked in: CPU: 0 PID: 0 Comm: swapper/0 Not tainted 5.10.109-rt65-stable-standard-00068-g6a5afc4b1217 #85 Hardware name: STM32 (Device Tree Support) [<c010a45d>] (unwind_backtrace) from [<c010766f>] (show_stack+0xb/0xc) [<c010766f>] (show_stack) from [<c06353ab>] (dump_stack+0x6f/0x84) [<c06353ab>] (dump_stack) from [<c01145e3>] (__warn+0x7f/0xa4) [<c01145e3>] (__warn) from [<c063386f>] (warn_slowpath_fmt+0x3b/0x74) [<c063386f>] (warn_slowpath_fmt) from [<c063b43d>] (__rt_mutex_trylock+0x37/0x62) [<c063b43d>] (__rt_mutex_trylock) from [<c063c053>] (rt_spin_trylock+0x7/0x16) [<c063c053>] (rt_spin_trylock) from [<c036a2f3>] (clk_enable_lock+0xb/0x80) [<c036a2f3>] (clk_enable_lock) from [<c036ba69>] (clk_core_enable_lock+0x9/0x18) [<c036ba69>] (clk_core_enable_lock) from [<c034e9f3>] (stm32_gpio_get+0x11/0x24) [<c034e9f3>] (stm32_gpio_get) from [<c034ef43>] (stm32_gpio_irq_trigger+0x1f/0x48) [<c034ef43>] (stm32_gpio_irq_trigger) from [<c014aa53>] (handle_fasteoi_irq+0x71/0xa8) [<c014aa53>] (handle_fasteoi_irq) from [<c0147111>] (generic_handle_irq+0x19/0x22) [<c0147111>] (generic_handle_irq) from [<c014752d>] (__handle_domain_irq+0x55/0x64) [<c014752d>] (__handle_domain_irq) from [<c0346f13>] (gic_handle_irq+0x53/0x64) [<c0346f13>] (gic_handle_irq) from [<c0100ba5>] (__irq_svc+0x65/0xc0) Exception stack(0xc0e01f18 to 0xc0e01f60) 1f00: 0000300c 00000000 1f20: 0000300c c010ff01 00000000 00000000 c0e00000 c0e07714 00000001 c0e01f78 1f40: c0e07758 00000000 ef7cd0ff c0e01f68 c010554b c0105542 40000033 ffffffff [<c0100ba5>] (__irq_svc) from [<c0105542>] (arch_cpu_idle+0xc/0x1e) [<c0105542>] (arch_cpu_idle) from [<c063be95>] (default_idle_call+0x21/0x3c) [<c063be95>] (default_idle_call) from [<c01324f7>] (do_idle+0xe3/0x1e4) [<c01324f7>] (do_idle) from [<c01327b3>] (cpu_startup_entry+0x13/0x14) [<c01327b3>] (cpu_startup_entry) from [<c0a00c13>] (start_kernel+0x397/0x3d4) [<c0a00c13>] (start_kernel) from [<00000000>] (0x0) ---[ end trace 0000000000000002 ]--- Power consumption measured on STM32MP157C DHCOM SoM is not increased or is below noise threshold.

[ Upstream commit 7e842d70 ] HyperFlash devices fail to probe: rpc-if-hyperflash rpc-if-hyperflash: probing of hyperbus device failed In HyperFlash or Octal-SPI Flash mode, the Transfer Data Enable bits (SPIDE) in the Manual Mode Enable Setting Register (SMENR) are derived from half of the transfer size, cfr. the rpcif_bits_set() helper function. However, rpcif_reg_{read,write}() does not take the bus size into account, and does not double all Manual Mode Data Register access sizes when communicating with a HyperFlash or Octal-SPI Flash device. Fix this, and avoid the back-and-forth conversion between transfer size and Transfer Data Enable bits, by explicitly storing the transfer size in struct rpcif, and using that value to determine access size in rpcif_reg_{read,write}(). Enforce that the "high" Manual Mode Read/Write Data Registers (SM[RW]DR1) are only used for 8-byte data accesses. While at it, forbid writing to the Manual Mode Read Data Registers, as they are read-only. Fixes: fff53a55 ("memory: renesas-rpc-if: Correct QSPI data transfer in Manual mode") Signed-off-by:

[ Upstream commit 46ff3df8 ] The pinout of the OMAP35 and DM37 variants of the SOM-LV are the same, but the macros which define the pinmuxing are different between OMAP3530 and DM3730. The pinmuxing was correct for for the DM3730, but wrong for the OMAP3530. Since the boot loader was correctly pin-muxing the pins, this was not obvious. As the bootloader not guaranteed to pinmux all the pins any more, this causes an issue, so the pinmux needs to be moved from a common file to their respective board files.

commit 7e0815b3 upstream. When a XEN_HVM guest uses the XEN PIRQ/Eventchannel mechanism, then PCI/MSI[-X] masking is solely controlled by the hypervisor, but contrary to XEN_PV guests this does not disable PCI/MSI[-X] masking in the PCI/MSI layer. This can lead to a situation where the PCI/MSI layer masks an MSI[-X] interrupt and the hypervisor grants the write despite the fact that it already requested the interrupt. As a consequence interrupt delivery on the affected device is not happening ever. Set pci_msi_ignore_mask to prevent that like it's done for XEN_PV guests already.

commit e4d8a299 upstream. If we pass too short string to "hex2bin" (and the string size without the terminating NUL character is even), "hex2bin" reads one byte after the terminating NUL character. This patch fixes it. Note that hex_to_bin returns -1 on error and hex2bin return -EINVAL on error - so we can't just return the variable "hi" or "lo" on error. This inconsistency may be fixed in the next merge window, but for the purpose of fixing this bug, we just preserve the existing behavior and return -1 and -EINVAL. Signed-off-by:

commit e5be1576 upstream. The function hex2bin is used to load cryptographic keys into device mapper targets dm-crypt and dm-integrity. It should take constant time independent on the processed data, so that concurrently running unprivileged code can't infer any information about the keys via microarchitectural convert channels. This patch changes the function hex_to_bin so that it contains no branches and no memory accesses. Note that this shouldn't cause performance degradation because the size of the new function is the same as the size of the old function (on x86-64) - and the new function causes no branch misprediction penalties. I compile-tested this function with gcc on aarch64 alpha arm hppa hppa64 i386 ia64 m68k mips32 mips64 powerpc powerpc64 riscv sh4 s390x sparc32 sparc64 x86_64 and with clang on aarch64 arm hexagon i386 mips32 mips64 powerpc powerpc64 s390x sparc32 sparc64 x86_64 to verify that there are no branches in the generated code.

commit ac875df4 upstream. The Samsung pinctrl drivers depend on OF_GPIO, which is part of GPIOLIB. ARMv7 Exynos platform selects GPIOLIB and Samsung pinctrl drivers. ARMv8 Exynos selects only the latter leading to possible wrong configuration on ARMv8 build: WARNING: unmet direct dependencies detected for PINCTRL_EXYNOS Depends on [n]: PINCTRL [=y] && OF_GPIO [=n] && (ARCH_EXYNOS [=y] || ARCH_S5PV210 || COMPILE_TEST [=y]) Selected by [y]: - ARCH_EXYNOS [=y] Always select the GPIOLIB from the Samsung pinctrl drivers to fix the issue. This requires removing of OF_GPIO dependency (to avoid recursive dependency), so add dependency on OF for COMPILE_TEST cases. Reported-by:

commit 1dc9f1a6 upstream. When ACPI is not enabled, cpuid_topo->llc_id = cpu_topo->llc_id = -1, which will set llc_sibling 0xff(...), this is misleading. Don't set llc_sibling(default 0) if we don't know the cache topology. Reviewed-by:
