They are issues: - if 'input_allocate_device()' fails and return NULL, there is no need to free anything and 'input_free_device()' call is a no-op. It can be axed. - 'ret' is known to be 0 at this point, so we must set it to a meaningful value before returning Fixes: 2562756d ("HID: add Alps I2C HID Touchpad-Stick support") Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

Syzbot reports that "hiddev" is used after it's free in hiddev_disconnect(). The hiddev_disconnect() function sets "hiddev->exist = 0;" so hiddev_release() can free it as soon as we drop the "existancelock" lock. This patch moves the mutex_unlock(&hiddev->existancelock) until after we have finished using it.

We have a HID touch device that reports its opens and shorts test results in HID buffers of size 8184 bytes. The maximum size of the HID buffer is currently set to 4096 bytes, causing probe of this device to fail. With this patch we increase the maximum size of the HID buffer to 8192 bytes, making device probe and acquisition of said buffers succeed.

In case a report is greater than HID_MAX_BUFFER_SIZE, it is truncated, but the report-number byte is not correctly handled. This results in a off-by-one in the following memset, causing a kernel Oops and ensuing system crash. Note: With commit 8ec321e9 ("HID: Fix slab-out-of-bounds read in hid_field_extract") I no longer hit the kernel Oops as we instead fail "controlled" at probe if there is a report too long in the HID report-descriptor. hid_report_raw_event() is an exported symbol, so presumabely we cannot always rely on this being the case.

Commit 8f18eca9 ("HID: ite: Add USB id match for Acer SW5-012 keyboard dock") added the USB id for the Acer SW5-012's keyboard dock to the hid-ite driver to fix the rfkill driver not working. Most keyboard docks with an ITE 8595 keyboard/touchpad controller have the "Wireless Radio Control" bits which need the special hid-ite driver on the second USB interface (the mouse interface) and their touchpad only supports mouse emulation, so using generic hid-input handling for anything but the "Wireless Radio Control" bits is fine. On these devices we simply bind to all USB interfaces. But unlike other ITE8595 using keyboard docks, the Acer Aspire Switch 10 (SW5-012)'s touchpad not only does mouse emulation it also supports HID-multitouch and all the keys including the "Wireless Radio Control" bits have been moved to the first USB interface (the keyboard intf). So we need hid-ite to handle the first (keyboard) USB interface and have it NOT bind to the second (mouse) USB interface so that that can be handled by hid-multitouch.c and we get proper multi-touch support. This commit changes the hid_device_id for the SW5-012 keyboard dock to only match on hid devices from the HID_GROUP_GENERIC group, this way hid-ite will not bind the the mouse/multi-touch interface which has HID_GROUP_MULTITOUCH_WIN_8 as group. This fixes the regression to mouse-emulation mode introduced by adding the keyboard dock USB id.

In the HID++ 2.0 function getBatteryInfo() from the BatteryVoltage (0x1001) feature, chargeStatus is only valid if extPower is active. Previously we were ignoring extPower, which resulted in wrong values. Example: With an unplugged mouse $ cat /sys/class/power_supply/hidpp_battery_0/status Charging This patch fixes that, it also renames charge_sts to flags as charge_sts can be confused with chargeStatus from the spec.

Pull arm64 updates from Will Deacon: "The changes are a real mixed bag this time around. The only scary looking one from the diffstat is the uapi change to asm-generic/mman-common.h, but this has been acked by Arnd and is actually just adding a pair of comments in an attempt to prevent allocation of some PROT values which tend to get used for arch-specific purposes. We'll be using them for Branch Target Identification (a CFI-like hardening feature), which is currently under review on the mailing list. New architecture features: - Support for Armv8.5 E0PD, which benefits KASLR in the same way as KPTI but without the overhead. This allows KPTI to be disabled on CPUs that are not affected by Meltdown, even is KASLR is enabled. - Initial support for the Armv8.5 RNG instructions, which claim to provide access to a high bandwidth, cryptographically secure hardware random number generator. As well as exposing these to userspace, we also use them as part of the KASLR seed and to seed the crng once all CPUs have come online. - Advertise a bunch of new instructions to userspace, including support for Data Gathering Hint, Matrix Multiply and 16-bit floating point. Kexec: - Cleanups in preparation for relocating with the MMU enabled - Support for loading crash dump kernels with kexec_file_load() Perf and PMU drivers: - Cleanups and non-critical fixes for a couple of system PMU drivers FPU-less (aka broken) CPU support: - Considerable fixes to support CPUs without the FP/SIMD extensions, including their presence in heterogeneous systems. Good luck finding a 64-bit userspace that handles this. Modern assembly function annotations: - Start migrating our use of ENTRY() and ENDPROC() over to the new-fangled SYM_{CODE,FUNC}_{START,END} macros, which are intended to aid debuggers Kbuild: - Cleanup detection of LSE support in the assembler by introducing 'as-instr' - Remove compressed Image files when building clean targets IP checksumming: - Implement optimised IPv4 checksumming routine when hardware offload is not in use. An IPv6 version is in the works, pending testing. Hardware errata: - Work around Cortex-A55 erratum #1530923 Shadow call stack: - Work around some issues with Clang's integrated assembler not liking our perfectly reasonable assembly code - Avoid allocating the X18 register, so that it can be used to hold the shadow call stack pointer in future ACPI: - Fix ID count checking in IORT code.

If we're sharing the ring across forks, then one process exiting means that we cancel ALL work and prevent future work. This is overly restrictive. As long as we cancel the work associated with the files from the current task, it's safe to let others persist. Normal fd close on exit will still wait (and cancel) pending work.

Host-aware SMR drives can be used with the commands to explicitly manage zone state, but they can also be used as normal disks. In the former case it makes perfect sense to allow partitions on them, in the latter it does not, just like for host managed devices. Add a check to add_partition to allow partitions on host aware devices, but give up any zone management capabilities in that case, which also catches the previously missed case of adding a partition vs just scanning it. Because sd can rescan the attribute at runtime it needs to check if a disk has partitions, for which a new helper is added to genhd.h.

This can be tested by running: echo add foo/.bar 1.2.3.4 >/proc/fs/afs/cells Note that we will also need to deal with: - Names ending in ".invalid" shouldn't be passed to the DNS. - Names that contain non-valid domainname chars shouldn't be passed to the DNS. - DNS replies that say "your-dns-needs-immediate-attention.<gTLD>" and replies containing A records that say 127.0.53.53 should be considered invalid. [https://www.icann.org/en/system/files/files/name-collision-mitigation-01aug14-en.pdf] but these need to be dealt with by the kafs-client DNS program rather than the kernel.

In fs_open(), 'vcc' is allocated through kmalloc() and assigned to 'atm_vcc->dev_data.' In the following execution, if an error occurs, e.g., there is no more free channel, an error code EBUSY or ENOMEM will be returned. However, 'vcc' is not deallocated, leading to memory leaks. Note that, in normal cases where fs_open() returns 0, 'vcc' will be deallocated in fs_close(). But, if fs_open() fails, there is no guarantee that fs_close() will be invoked. To fix this issue, deallocate 'vcc' before the error code is returned. Signed-off-by: Wenwen Wang <wenwen@cs.uga.edu> Signed-off-by: David S. Miller <davem@davemloft.net>

Pull btrfs fix from David Sterba: "Here's a last minute fix for a regression introduced in this development cycle.

Saeed Mahameed says: ==================== Mellanox, mlx5 fixes 2020-01-24 This series introduces some fixes to mlx5 driver. Please pull and let me know if there is any problem. Merge conflict: once merge with net-next, a contextual conflict will appear in drivers/net/ethernet/mellanox/mlx5/core/eswitch_offloads.c since the code moved in net-next. To resolve, just delete ALL of the conflicting hunk from net. So sorry for the small mess ..

Hitting ENOSPC is possible and could happen when the block group is set read-only, preventing NOCOW writes to the area that's being accessed by dev-replace. This has happend with scratch devices of size 12G but not with 5G and 20G, so this is depends on timing and other activity on the filesystem. The whole replace operation is restartable, the space state should be examined by the user in any case. The error code is propagated back to the ioctl caller so the kernel warning is causing false alerts. Signed-off-by: David Sterba <dsterba@suse.com>
