There are a few minor bug fixes, but those are the noteworthy changes: - Support for 5.12 Linux kernels, - Support recent stable kernel branches 4.14, 4.19, 5.4, - Support for newer Ubuntu 4.15, 5.4 and RHEL 8.2/8.3 kernels, - Fix: increment buffer offset when failing to copy from user-space: Upon failure to copy from user-space due to failing access ok check, the ring buffer offset is not incremented, which could generate unreadable traces because we don't account for the padding we write into the ring buffer. Note that this typically won't affect a common use-case of copying strings from user-space, because unless mprotect is invoked within a narrow race window (between user strlen and user strcpy), the strlen will fail on access ok when calculating the space to reserve, which will match what happens on strcpy.
