Title:
seccomp_bpf in seccomp from ubuntu_kernel_selftests failed to build on
B-5.4
Status in ubuntu-kernel-tests:
Fix Released
Status in linux package in Ubuntu:
Invalid
Status in linux source package in Focal:
Fix Committed
Bug description:
[Impact]
Test fails to build in selftests/seccomp/seccomp_bpf.c with
'error: storage size of ‘md’ isn’t known' due to the type
struct seccomp_metadata not being defined for B/5.4 kernels.
[Test case]
Test successfully builds and test cases pass both on Bionic/5.4 and on
Focal
[Fixes]
Unconditionally define struct seccomp_metadata.
Remove linux/ptrace.h where a definition of seccomp_metadata is already being
defined in Focal.
[Potential regression]
There could be future build failures if glibc headers get updated to
include definitions of struct seccomp_metadata or if linux/ptrace.h gets
updated
to include needed definitions.
