commit 2e746942 upstream. The usec part of the timeval is defined as __kernel_suseconds_t tv_usec; /* microseconds */ Arnd noticed that sparc64 is the only architecture that defines __kernel_suseconds_t as int rather than long. This breaks the current y2038 fix for kernel as we only access and define the timeval struct for non-kernel use cases. But, this was hidden by an another typo in the use of __KERNEL__ qualifier. Fix the typo, and provide an override for sparc64. Fixes: 152194fe ("Input: extend usable life of event timestamps to 2106 on 32 bit systems") Reported-by:

commit fe2bfd0d upstream. Add support for the SteelSeries Stratus Duo, a wireless Xbox 360 controller. The Stratus Duo ships with a USB dongle to enable wireless connectivity, but it can also function as a wired controller by connecting it directly to a PC via USB, hence the need for two USD PIDs. 0x1430 is the dongle, and 0x1431 is the controller.

commit ef68e831 upstream. When executing add_credits() we currently call cifs_reconnect() if the number of credits is zero and there are no requests in flight. In this case we may call cifs_reconnect() recursively twice and cause memory corruption given the following sequence of functions: mid1.callback() -> add_credits() -> cifs_reconnect() -> -> mid2.callback() -> add_credits() -> cifs_reconnect(). Fix this by avoiding to call cifs_reconnect() in add_credits() and checking for zero credits in the demultiplex thread. Cc: <stable@vger.kernel.org> Signed-off-by:

commit acc58d0b upstream. When doing MTU i/o we need to leave some credits for possible reopen requests and other operations happening in parallel. Currently we leave 1 credit which is not enough even for reopen only: we need at least 2 credits if durable handle reconnect fails. Also there may be other operations at the same time including compounding ones which require 3 credits at a time each. Fix this by leaving 8 credits which is big enough to cover most scenarios. Was able to reproduce this when server was configured to give out fewer credits than usual. The proper fix would be to reconnect a file handle first and then obtain credits for an MTU request but this leads to bigger code changes and should happen in other patches.

commit bfd8d8fe upstream. When CONFIG_VGACON_SOFT_SCROLLBACK is selected, the VGA display memory index and vc_visible_origin don't change when scrollback is activated. The actual screen content is saved away and the scrollbackdata is copied over it. However the vt code, and /dev/vcs devices in particular, still expect vc_origin to always point at the actual screen content not the displayed scrollback content. So adjust vc_origin to point at the saved screen content when scrollback is active and set it back to vc_visible_origin when restoring the screen. This fixes /dev/vcsa<n> that return scrollback content when they shouldn't (onli /dev/vcsa without a number should), and also fixes /dev/vcsu that should return scrollback content when scrollback is active but currently doesn't. An unnecessary call to vga_set_mem_top() is also removed. Signed-off-by:

commit ba50bf1c upstream. fc96df16 is good and can already fix the "return stack garbage" issue, but let's also improve hv_ringbuffer_get_debuginfo(), which would silently return stack garbage, if people forget to check channel->state or ring_info->ring_buffer, when using the function in the future. Having an error check in the function would eliminate the potential risk. Add a Fixes tag to indicate the patch depdendency.

commit da8ced36 upstream. Hyper-V memory hotplug protocol has 2M granularity and in Linux x86 we use 128M. To deal with it we implement partial section onlining by registering custom page onlining callback (hv_online_page()). Later, when more memory arrives we try to online the 'tail' (see hv_bring_pgs_online()). It was found that in some cases this 'tail' onlining causes issues: BUG: Bad page state in process kworker/0:2 pfn:109e3a page:ffffe08344278e80 count:0 mapcount:1 mapping:0000000000000000 index:0x0 flags: 0xfffff80000000() raw: 000fffff80000000 dead000000000100 dead000000000200 0000000000000000 raw: 0000000000000000 0000000000000000 0000000000000000 0000000000000000 page dumped because: nonzero mapcount ...

Turns out that we now have deferred struct page initialization for memory hotplug so e.g. memory_block_action() in drivers/base/memory.c does pages_correctly_probed() check and in that check it avoids inspecting struct pages and checks sections instead. But in Hyper-V balloon driver we do PageReserved(pfn_to_page()) check and this is now wrong. Switch to checking online_section_nr() instead. Signed-off-by:

commit fc01d8c6 upstream. Fix __might_sleep warning[1] in tty/n_hdlc.c read due to copy_to_user call while current is TASK_INTERRUPTIBLE. This is a false positive since the code path does not depend on current state remaining TASK_INTERRUPTIBLE. The loop breaks out and sets TASK_RUNNING after calling copy_to_user. This patch supresses the warning by setting TASK_RUNNING before calling copy_to_user. [1] https://syzkaller.appspot.com/bug?id=17d5de7f1fcab794cb8c40032f893f52de899324Signed-off-by:

commit bb364890 upstream. Because the irq was requested through device managed resources API (devm_request_threaded_irq()) it was freed after meson_mmc_remove() completion, thus after mmc_free_host() has reclaimed meson_host memory. As this irq is IRQF_SHARED, while using CONFIG_DEBUG_SHIRQ, its handler get called by free_irq(). So meson_mmc_irq() was called after the meson_host memory reclamation and was using invalid memory. We ended up with the following scenario: device_release_driver() meson_mmc_remove() mmc_free_host() /* Freeing host memory */ ... devres_release_all() devm_irq_release() __free_irq() meson_mmc_irq() /* Uses freed memory */ To avoid this, the irq is released in meson_mmc_remove() and in mseon_mmc_probe() error path before mmc_free_host() gets called.

commit b7cb707c upstream. smp_rescan_cpus() is called without the device_hotplug_lock, which can lead to a dedlock when a new CPU is found and immediately set online by a udev rule. This was observed on an older kernel version, where the cpu_hotplug_begin() loop was still present, and it resulted in hanging chcpu and systemd-udev processes. This specific deadlock will not show on current kernels. However, there may be other possible deadlocks, and since smp_rescan_cpus() can still trigger a CPU hotplug operation, the device_hotplug_lock should be held. For reference, this was the deadlock with the old cpu_hotplug_begin() loop: chcpu (rescan) systemd-udevd echo 1 > /sys/../rescan -> smp_rescan_cpus() -> (*) get_online_cpus() (increases refcount) -> smp_add_present_cpu() (new CPU found) -> register_cpu() -> device_add() -> udev "add" event triggered -----------> udev rule sets CPU online -> echo 1 > /sys/.../online -> lock_device_hotplug_sysfs() (this is missing in rescan path) -> device_online() -> (**) device_lock(new CPU dev) -> cpu_up() -> cpu_hotplug_begin() (loops until refcount == 0) -> deadlock with (*) -> bus_probe_device() -> device_attach() -> device_lock(new CPU dev) -> deadlock with (**) Fix this by taking the device_hotplug_lock in the CPU rescan path.

commit 03aa047e upstream. Right now the early machine detection code check stsi 3.2.2 for "KVM" and set MACHINE_IS_VM if this is different. As the console detection uses diagnose 8 if MACHINE_IS_VM returns true this will crash Linux early for any non z/VM system that sets a different value than KVM. So instead of assuming z/VM, do not set any of MACHINE_IS_LPAR, MACHINE_IS_VM, or MACHINE_IS_KVM. CC: stable@vger.kernel.org Reviewed-by:

commit a3866208 upstream. The ASCE of an mm_struct can be modified after a task has been created, e.g. via crst_table_downgrade for a compat process. The active_mm logic to avoid the switch_mm call if the next task is a kernel thread can lead to a situation where switch_mm is called where 'prev == next' is true but 'prev->context.asce == next->context.asce' is not. This can lead to a situation where a CPU uses the outdated ASCE to run a task. The result can be a crash, endless loops and really subtle problem due to TLBs being created with an invalid ASCE.

commit a3010a04 upstream. In setup_arch_memory we reserve the memory area wherein the kernel is located. Current implementation may reserve more memory than it actually required in case of CONFIG_LINUX_LINK_BASE is not equal to CONFIG_LINUX_RAM_BASE. This happens because we calculate start of the reserved region relatively to the CONFIG_LINUX_RAM_BASE and end of the region relatively to the CONFIG_LINUX_RAM_BASE. For example in case of HSDK board we wasted 256MiB of physical memory: ------------------->8------------------------------ Memory: 770416K/1048576K available (5496K kernel code, 240K rwdata, 1064K rodata, 2200K init, 275K bss, 278160K reserved, 0K cma-reserved) ------------------->8------------------------------ Fix that.

commit e6a72b7d upstream. ARCv2 optimized memset uses PREFETCHW instruction for prefetching the next cache line but doesn't ensure that the line is not past the end of the buffer. PRETECHW changes the line ownership and marks it dirty, which can cause issues in SMP config when next line was already owned by other core. Fix the issue by avoiding the PREFETCHW Some more details: The current code has 3 logical loops (ignroing the unaligned part) (a) Big loop for doing aligned 64 bytes per iteration with PREALLOC (b) Loop for 32 x 2 bytes with PREFETCHW (c) any left over bytes loop (a) was already eliding the last 64 bytes, so PREALLOC was safe. The fix was removing PREFETCW from (b). Another potential issue (applicable to configs with 32 or 128 byte L1 cache line) is that PREALLOC assumes 64 byte cache line and may not do the right thing specially for 32b. While it would be easy to adapt, there are no known configs with those lie sizes, so for now, just compile out PREALLOC in such cases. Signed-off-by:

commit 667e9334 upstream. During the bootup of the kernel, the DAPM bias level is in the OFF state. As soon as the DAPM framework kicks in it pushes the codec into STANDBY state. The probe function doesn't prepare the clock, and STANDBY state does a clk_disable_unprepare() without checking the previous state. This leads to an OOPS. Not transitioning from an OFF state to the STANDBY state fixes the problem. Signed-off-by:

commit 91f7d2e8 upstream. The patch "usb: simplify usbport trigger" together with "leds: triggers: add device attribute support" caused an regression for the usbport trigger. it will no longer enumerate any active usb hub ports under the "ports" directory in the sysfs class directory, if the usb host drivers are fully initialized before the usbport trigger was loaded. The reason is that the usbport driver tries to register the sysfs entries during the activate() callback. And this will fail with -2 / ENOENT because the patch "leds: triggers: add device attribute support" made it so that the sysfs "ports" group was only being added after the activate() callback succeeded. This version of the patch reverts parts of the "usb: simplify usbport trigger" patch and restores usbport trigger's functionality. Fixes: 6f7b0bad ("usb: simplify usbport trigger") Signed-off-by:

[ Upstream commit 13d7f463 ] TCP transmission with MSG_ZEROCOPY fails if the peer closes its end of the connection and so transitions this socket to CLOSE_WAIT state. Transmission in close wait state is acceptable. Other similar tests in the stack (e.g., in FastOpen) accept both states. Relax this test, too.
