==================== Changes in man-pages-3.77 ====================


New and rewritten pages
-----------------------

seccomp.2
    Kees Cook, Michael Kerrisk, Will Drewry  [Andy Lutomirski]
        New page documenting seccomp(2)
            Combines documentation from prctl, in-kernel seccomp_filter.txt
            and dropper.c, along with details specific to the new system call.


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

netlink.7
    Stephan Mueller  [Michael Kerrisk]
        Add NETLINK_CRYPTO


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

perf_event_open.2
    Vince Weaver
        Clarify the PERF_FLAG_FD_* flags
            This change clarifies the behavior of the PERF_FLAG_FD_OUTPUT and
            PERF_FLAG_FD_NO_GROUP flags to perf_event_open(), and removes
            the related FIXME comments.

            While writing tests to validate the behavior of these flags I
            discovered that PERF_FLAG_FD_OUTPUT has been broken since the
            2.6.35 kernel release.

prctl.2
    Dave Hansen [Michael Kerrisk]
        Add description of Intel MPX calls
            The 3.19 kernel will have support for Intel MPX, including
            a pair of new prctl() calls (PR_MPX_ENABLE_MANAGEMENT and
            PR_MPX_DISABLE_MANAGEMENT) for enabling and disabling the
            kernel's management of the "bounds tables".  Add a
            descriptions of the interface.

setns.2
pid_namespaces.7
    Mike Frysinger
        Elaborate discussion of the PID namespace descendant limitation
            The setns(2) man page already mentions that CLONE_NEWPID may only
            be used with descendant namespaces, but this nuance could be
            listed in a few more places so it is not missed.

sigaction.2
    Michael Kerrisk
        Add siginfo_t fields for SECCOMP_RET_TRAP

random.4
    Heinrich Schuchardt
        Describe handling of O_NONBLOCK
            /dev/random and /dev/urandom treat O_NONBLOCK differently.
            This should be described in the manpage.
    Heinrich Schuchardt
        Mention PRNG used by urandom
            /dev/urandom uses a pseudo-random number generator to replace
            missing entropy.

proc.5
    Michael Kerrisk
        Document "Seccomp" field of /proc/PID/status

tcp.7
    Troy Davis
        Clarify tcp_tw_recycle on Internet-facing hosts
            Clarify that tcp_tw_recycle will break communication with many
            general-purpose remote Internet hosts (namely, remote NAT devices)
            even when the Linux device itself is not behind NAT.
