| * | UPSTREAM: arm64: vdso: fix clock_getres for 4GiB-aligned res | Mark Rutland | 2017-12-14 | 1 | -1/+1 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | (cherry pick from commit c80ed088a519da53f27b798a69748eaabc66aadf) The vdso tries to check for a NULL res pointer in __kernel_clock_getres, but only checks the lower 32 bits as is uses CBZ on the W register the res pointer is held in. Thus, if the res pointer happened to be aligned to a 4GiB boundary, we'd spuriously skip storing the timespec to it, while returning a zero error code to the caller. Prevent this by checking the whole pointer, using CBZ on the X register the res pointer is held in.

| * | UPSTREAM: arm64: vdso: minor ABI fix for clock_getres | Nathan Lynch | 2017-12-14 | 1 | -1/+1 |
| | | | | | | | | | | | | | | | | | | | | | | | (cherry picked from commit e1b6b6ce55a0a25c8aa8af019095253b2133a41a) The vdso implementation of clock_getres currently returns 0 (success) whenever a null timespec is provided by the caller, regardless of the clock id supplied. This behavior is incorrect. It should fall back to syscall when an unrecognized clock id is passed, even when the timespec argument is null. This ensures that clock_getres always returns an error for invalid clock ids.
