+Author: Damien Miller <djm@mindrot.org>
+Date:   Tue Mar 14 12:24:47 2017 +1100
+    Fix weakness in seccomp-bpf sandbox arg inspection
+    
+    Syscall arguments are passed via an array of 64-bit values in struct
+    seccomp_data, but we were only inspecting the bottom 32 bits and not
+    even those correctly for BE systems.
+    
+    Fortunately, the only case argument inspection was used was in the
+    socketcall filtering so using this for sandbox escape seems
+    impossible.

-    UpdateHostKeys fixes:
-    
-    I accidentally changed the format of the hostkeys@openssh.com messages
-    last week without changing the extension name, and this has been causing
-    connection failures for people who are running -current. First reported
-    by sthen@
-    
-    s/hostkeys@openssh.com/hostkeys-00@openssh.com/
-    Change the name of the proof message too, and reorder it a little.
-    
-    Also, UpdateHostKeys=ask is incompatible with ControlPersist (no TTY
-    available to read the response) so disable UpdateHostKeys if it is in
-    ask mode and ControlPersist is active (and document this)

-    
-    Add a hostkeys@openssh.com protocol extension (global request) for
-    a server to inform a client of all its available host key after
-    authentication has completed. The client may record the keys in
-    known_hosts, allowing it to upgrade to better host key algorithms
-    and a server to gracefully rotate its keys.
-    
-    The client side of this is controlled by a UpdateHostkeys config
-    option (default on).

-commit 589e69fd82724cfc9738f128e4771da2e6405d0d
-Author: djm@openbsd.org <djm@openbsd.org>
-Date:   Sun Jan 18 19:53:58 2015 +0000
-    upstream commit
-    
-    make the signature fuzzing test much more rigorous:
-     ensure that the fuzzed input cases do not match the original (using new
-     fuzz_matches_original() function) and check that the verification fails in
-     each case
-commit 80603c0daa2538c349c1c152405580b164d5475f
-Author: djm@openbsd.org <djm@openbsd.org>
-Date:   Sun Jan 18 19:52:44 2015 +0000
-    upstream commit
-    
-    add a fuzz_matches_original() function to the fuzzer to
-     detect fuzz cases that are identical to the original data. Hacky
-     implementation, but very useful when you need the fuzz to be different, e.g.
-     when verifying signature

-    better dumps from the fuzzer (shown on errors) -
-     include the original data as well as the fuzzed copy.

-    upstream commit
-    
-    introduce hostkeys_foreach() to allow iteration over a
-     known_hosts file or controlled subset thereof. This will allow us to pull out
-     some ugly and duplicated code, and will be used to implement hostkey rotation
-     later.

-     LOGIN_NAME_MAX, etc.  Change MIN() and MAX() to local definitions of
-     MINIMUM() and MAXIMUM() where sensible to avoid pulling in the pollution.
-     These are the files confirmed through binary verification. ok guenther,

-    upstream commit
-    
-    deprecate key_load_private_pem() and
-     sshkey_load_private_pem() interfaces. Refactor the generic key loading API to
-     not require pathnames to be specified (they weren't really used).
-    
-    Fixes a few other things en passant:
-    
-    Makes ed25519 keys work for hostbased authentication (ssh-keysign
-    previously used the PEM-only routines).
-    
-    Fixes key comment regression bz#2306: key pathnames were being lost as
-    comment fields.

-    avoid uninitialised free of ldns_res
-    
-    If an invalid rdclass was passed to getrrsetbyname() then
-    this would execute a free on an uninitialised pointer.

             If UsePAM is enabled, you will not be able to run sshd(8) as a
             non-root user.  The default is no.
-     UsePrivilegeSeparation
-             Specifies whether sshd(8) separates privileges by creating an
-             unprivileged child process to deal with incoming network traffic.
-             After successful authentication, another process will be created
-             that has the privilege of the authenticated user.  The goal of
-             privilege separation is to prevent privilege escalation by
-             containing any corruption within the unprivileged processes.  The
-             argument must be yes, no, or sandbox.  If UsePrivilegeSeparation
-             is set to sandbox then the pre-authentication unprivileged
-             process is subject to additional restrictions.  The default is
