Pull ipc regression fixes from Arnd Bergmann: "Fix ipc regressions from y2038 patches These are two regression fixes for bugs that got introduced during the system call rework that went into linux-5.1 but only bisected and fixed now: - One patch affects semtimedop() on many of the less common 32-bit architectures, this just needs a single-line bugfix. - The other affects only sparc64 and has a slightly more invasive workaround to apply the same change to sparc64 that was done to the generic code used everywhere else" * tag 'ipc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: ipc: fix sparc64 ipc() wrapper ipc: fix semtimedop for generic 32-bit architectures

include/linux/compiler.h: fix Oops for Clang-compiled kernels

2019-09-08T12:53:58Z

GCC unescapes escaped string section names while Clang does not. Because __section uses the `#` stringification operator for the section name, it doesn't need to be escaped. This fixes an Oops observed in distro's that use systemd and not net.core.bpf_jit_enable=1, when their kernels are compiled with Clang.

ipc: fix sparc64 ipc() wrapper

2019-09-07T19:42:25Z

Matt bisected a sparc64 specific issue with semctl, shmctl and msgctl to a commit from my y2038 series in linux-5.1, as I missed the custom sys_ipc() wrapper that sparc64 uses in place of the generic version that I patched. The problem is that the sys_{sem,shm,msg}ctl() functions in the kernel now do not allow being called with the IPC_64 flag any more, resulting in a -EINVAL error when they don't recognize the command. Instead, the correct way to do this now is to call the internal ksys_old_{sem,shm,msg}ctl() functions to select the API version. As we generally move towards these functions anyway, change all of sparc_ipc() to consistently use those in place of the sys_*() versions, and move the required ksys_*() declarations into linux/syscalls.h The IS_ENABLED(CONFIG_SYSVIPC) check is required to avoid link errors when ipc is disabled.

Looks like the Bios of the Lenovo Legion Y7000 is using ELAN061B when the actual device is supposed to be used with hid-multitouch. Remove it from the list of the supported device, hoping that no one will complain about the loss in functionality.

ipc: fix semtimedop for generic 32-bit architectures

2019-09-06T19:49:24Z

As Vincent noticed, the y2038 conversion of semtimedop in linux-5.1 broke when commit 00bf25d693e7 ("y2038: use time32 syscall names on 32-bit") changed all system calls on all architectures that take a 32-bit time_t to point to the _time32 implementation, but left out semtimedop in the asm-generic header. This affects all 32-bit architectures using asm-generic/unistd.h: h8300, unicore32, openrisc, nios2, hexagon, c6x, arc, nds32 and csky. The notable exception is riscv32, which has dropped support for the time32 system calls entirely.
