Kees Cook aef078b882 bpf: Check correct cred for CAP_SYSLOG in bpf_dump_raw_ok() ... commit 63960260457a02af2a6cb35d75e6bdb17299c882 upstream. When evaluating access control over kallsyms visibility, credentials at open() time need to be used, not the "current" creds (though in BPF's case, this has likely always been the same). Plumb access to associated file->f_cred down through bpf_dump_raw_ok() and its callers now that kallsysm_show_value() has been refactored to take struct cred.
