The posix timer overrun handling is broken because the forwarding functions can return a huge number of overruns which does not fit in an int. As a consequence timer_getoverrun(2) and siginfo::si_overrun can turn into random number generators. The k_clock::timer_forward() callbacks return a 64 bit value now. Make k_itimer::ti_overrun[_last] 64bit as well, so the kernel internal accounting is correct. 3Remove the temporary (int) casts. Add a helper function which clamps the overrun value returned to user space via timer_getoverrun(2) or siginfo::si_overrun limited to a positive value between 0 and INT_MAX. INT_MAX is an indicator for user space that the overrun value has been clamped.

The posix timer ti_overrun handling is broken because the forwarding functions can return a huge number of overruns which does not fit in an int. As a consequence timer_getoverrun(2) and siginfo::si_overrun can turn into random number generators. As a first step to address that let the timer_forward() callbacks return the full 64 bit value. Cast it to (int) temporarily until k_itimer::ti_overrun is converted to 64bit and the conversion to user space visible values is sanitized.

timer_set/gettime and timerfd_set/get apis use struct itimerspec at the user interface layer. struct itimerspec is not y2038-safe. Change these interfaces to use y2038-safe struct __kernel_itimerspec instead. This will help define new syscalls when 32bit architectures select CONFIG_64BIT_TIME.

struct itimerspec is not y2038-safe. Introduce a new struct __kernel_itimerspec based on the kernel internal y2038-safe struct itimerspec64. The definition of struct __kernel_itimerspec includes two struct __kernel_timespec. Since struct __kernel_timespec has the same representation in native and compat modes, so does struct __kernel_itimerspec. This helps have a common entry point for syscalls using struct __kernel_itimerspec. New y2038-safe syscalls will use this new type. Since most of the new syscalls are just an update to the native syscalls with the type update, place the new definition under CONFIG_64BIT_TIME. This helps architectures that do not support the above config to keep using the old definition of struct itimerspec. Also change the get/put_itimerspec64 to use struct__kernel_itimerspec. This will help 32 bit architectures to use the new syscalls when architectures select CONFIG_64BIT_TIME.

In smb3_init_transform_rq(), 'orig_len' was only counting the request length, but forgot to count any data pages in the request. Writing or creating files with the 'seal' mount option was broken. In addition, do some code refactoring by exporting smb2_rqst_len() to calculate the appropriate packet size and avoid duplicating the same calculation all over the code. The start of the io vector is either the rfc1002 length (4 bytes) or a SMB2 header which is always > 4. Use this fact to check and skip the rfc1002 length if requested.

The specified locations are not right. Fix the wildcard logic to point to the correct directories. Without that, get-maintainer won't get things right: $ ./scripts/get_maintainer.pl --no-git-fallback --no-r --no-n --no-l -f Documentation/devicetree/bindings/arm/cpu-enable-method/nuvoton,npcm750-smp robh+dt@kernel.org (maintainer:OPEN FIRMWARE AND FLATTENED DEVICE TREE BINDINGS) mark.rutland@arm.com (maintainer:OPEN FIRMWARE AND FLATTENED DEVICE TREE BINDINGS) After the patch, it will properly point to NPCM arch maintainers: $ ./scripts/get_maintainer.pl --no-git-fallback --no-r --no-n --no-l -f Documentation/devicetree/bindings/arm/cpu-enable-method/nuvoton,npcm750-smp avifishman70@gmail.com (supporter:ARM/NUVOTON NPCM ARCHITECTURE) tmaimon77@gmail.com (supporter:ARM/NUVOTON NPCM ARCHITECTURE) robh+dt@kernel.org (maintainer:OPEN FIRMWARE AND FLATTENED DEVICE TREE BINDINGS) mark.rutland@arm.com (maintainer:OPEN FIRMWARE AND FLATTENED DEVICE TREE BINDINGS) Cc: Avi Fishman <avifishman70@gmail.com> Cc: Tomer Maimon <tmaimon77@gmail.com> Cc: Patrick Venture <venture@google.com> Cc: Nancy Yuen <yuenn@google.com> Cc: Brendan Higgins <brendanhiggins@google.com> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org> Acked-by: Jonathan Corbet <corbet@lwn.net>

The alsa parameters file was renamed to alsa-configuration.rst. With regards to OSS, it got retired as a hole by at changeset 727dede0 ("sound: Retire OSS"). So, it doesn't make sense to keep mentioning it at kernel-parameters.txt.
