==================== Changes in man-pages-5.01 ====================

Released: 2019-05-09, Munich


Newly documented interfaces in existing pages
---------------------------------------------

tsearch.3
    Florian Weimer  [Michael Kerrisk]
        Document the twalk_r() function added in glibc 2.30


Changes to individual pages
---------------------------

bpf.2
    Michael Kerrisk
        Update kernel version info for JIT compiler

clone.2
    Michael Kerrisk  [Jakub Nowak]
        CLONE_CHILD_SETTID has effect before clone() returns *in the child*
            CLONE_CHILD_SETTID may not have had effect by the time clone()
            returns in the parent, which could be relevant if the
            CLONE_VM flag is employed. The relevant kernel code is in
            schedule_tail(), which is called in ret_from_fork()
            in the child.

            See https://bugzilla.kernel.org/show_bug.cgi?id=203105

execve.2
    Michael Kerrisk
        Note that stack+environ size is also limited to 3/4 of _STK_LIM
            In fs/exec.c::prepare_arg_pages(), we have:

                    limit = _STK_LIM / 4 * 3;
                    limit = min(limit, bprm->rlim_stack.rlim_cur / 4);
