arch: add pidfd and io_uring syscalls everywhere

2019-04-15T14:31:17Z

Add the io_uring and pidfd_send_signal system calls to all architectures. These system calls are designed to handle both native and compat tasks, so all entries are the same across architectures, only arm-compat and the generic tale still use an old format.

Pull char/misc driver updates from Greg KH: "Here is the big char/misc driver patch pull request for 5.1-rc1. The largest thing by far is the new habanalabs driver for their AI accelerator chip. For now it is in the drivers/misc directory but will probably move to a new directory soon along with other drivers of this type. Other than that, just the usual set of individual driver updates and fixes. There's an "odd" merge in here from the DRM tree that they asked me to do as the MEI driver is starting to interact with the i915 driver, and it needed some coordination. All of those patches have been properly acked by the relevant subsystem maintainers.

y2038: add 64-bit time_t syscalls to all 32-bit architectures

2019-02-06T23:13:28Z

This adds 21 new system calls on each ABI that has 32-bit time_t today. All of these have the exact same semantics as their existing counterparts, and the new ones all have macro names that end in 'time64' for clarification. This gets us to the point of being able to safely use a C library that has 64-bit time_t in user space. There are still a couple of loose ends to tie up in various areas of the code, but this is the big one, and should be entirely uncontroversial at this point. In particular, there are four system calls (getitimer, setitimer, waitid, and getrusage) that don't have a 64-bit counterpart yet, but these can all be safely implemented in the C library by wrapping around the existing system calls because the 32-bit time_t they pass only counts elapsed time, not time since the epoch. They will be dealt with later. Signed-off-by: Arnd Bergmann Acked-by: Heiko Carstens Acked-by: Geert Uytterhoeven Acked-by: Catalin Marinas

y2038: rename old time and utime syscalls

2019-02-06T23:13:28Z

The time, stime, utime, utimes, and futimesat system calls are only used on older architectures, and we do not provide y2038 safe variants of them, as they are replaced by clock_gettime64, clock_settime64, and utimensat_time64. However, for consistency it seems better to have the 32-bit architectures that still use them call the "time32" entry points (leaving the traditional handlers for the 64-bit architectures), like we do for system calls that now require two versions. Note: We used to always define __ARCH_WANT_SYS_TIME and __ARCH_WANT_SYS_UTIME and only set __ARCH_WANT_COMPAT_SYS_TIME and __ARCH_WANT_SYS_UTIME32 for compat mode on 64-bit kernels. Now this is reversed: only 64-bit architectures set __ARCH_WANT_SYS_TIME/UTIME, while we need __ARCH_WANT_SYS_TIME32/UTIME32 for 32-bit architectures and compat mode. The resulting asm/unistd.h changes look a bit counterintuitive. This is only a cleanup patch and it should not change any behavior.

y2038: use time32 syscall names on 32-bit

2019-02-06T23:13:28Z

This is the big flip, where all 32-bit architectures set COMPAT_32BIT_TIME and use the _time32 system calls from the former compat layer instead of the system calls that take __kernel_timespec and similar arguments. The temporary redirects for __kernel_timespec, __kernel_itimerspec and __kernel_timex can get removed with this. It would be easy to split this commit by architecture, but with the new generated system call tables, it's easy enough to do it all at once, which makes it a little easier to check that the changes are the same in each table.

arch: add pkey and rseq syscall numbers everywhere

2019-01-25T16:22:50Z

Most architectures define system call numbers for the rseq and pkey system calls, even when they don't support the features, and perhaps never will. Only a few architectures are missing these, so just define them anyway for consistency. If we decide to add them later to one of these, the system call numbers won't get out of sync then.
