The ptrace(2) man page says that PTRACE_SEIZE, PTRACE_LISTEN, and PTRACE_INTERRUPT was introduced in Linux 3.4. In fact, this was added in 3.1: $ git diff v3.0 v3.1 include/linux/ptrace.h | grep SEIZE +#define PTRACE_SEIZE 0x4206 +/* flags in @data for PTRACE_SEIZE */ +#define PTRACE_SEIZE_DEVEL 0x80000000 /* temp flag for development */Yes, PTRACE_SEIZE was introduced by commit v3.1-rc1~308^2~28, but it had to be used along with a temporary flag PTRACE_SEIZE_DEVEL, which was removed later by commit v3.4-rc1~109^2~20. That is, between v3.0 and v3.4 we had a test mode of PTRACE_SEIZE API, which was not compatible with the current PTRACE_SEIZE API introduced in Linux 3.4.
So, it sounds like the page is good as it stands, right?
