-+On systems which do not define @code{NAME_MAX}, it may not be possible

-+length of the buffer for the directory entry.
-+
-+@item
-+On some systems, @code{readdir_r} cannot read directory entries with
-+very long names.  If such a name is encountered, @theglibc{}
-+implementation of @code{readdir_r} returns with an error code of
-+@code{ENAMETOOLONG} after the final directory entry has been read.  On
-+other systems, @code{readdir_r} may return successfully, but the
-+@code{d_name} member may not be NUL-terminated or may be truncated.
-+
-+@item
-+POSIX-1.2008 does not guarantee that @code{readdir} is thread-safe,
-+even when access to the same @var{dirstream} is serialized.  But in
-+current implementations (including @theglibc{}), it is safe to call
-+@code{readdir} concurrently on different @var{dirstream}s, so there is
-+no need to use @code{readdir_r} in most multi-threaded programs.  In
-+the rare case that multiple threads need to read from the same
-+@var{dirstream}, it is still better to use @code{readdir} and external
-+synchronization.
-+

-+It is expected that future versions of POSIX will obsolete
-+@code{readdir_r} and mandate the level of thread safety for

-
-    Fix stack overflow due to large AF_INET6 requests
-    
-    Resolves #16072 (CVE-2013-4458).
-    
-    This patch fixes another stack overflow in getaddrinfo when it is
-    called with AF_INET6.  The AF_UNSPEC case was fixed as CVE-2013-1914,
-    but the AF_INET6 case went undetected back then.

-Author: Carlos O'Donell <carlos@redhat.com>
-Date:   Mon Sep 23 00:52:09 2013 -0400
-
-    BZ #15754: CVE-2013-4788
-    
-    The pointer guard used for pointer mangling was not initialized for
-    static applications resulting in the security feature being disabled.
-    The pointer guard is now correctly initialized to a random value for
-    static applications. Existing static applications need to be
-    recompiled to take advantage of the fix.
-    
-    The test tst-ptrguard1-static and tst-ptrguard1 add regression
-    coverage to ensure the pointer guards are sufficiently random
-    and initialized to a default value.

+
+Fix sign of input to bsloww1 (BZ #16623)
+
+In 84ba214c, I removed some redundant sign computations and in the
+process, I incorrectly got rid of a temporary variable, thus passing
+the absolute value of the input to bsloww1.  This caused #16623.
+
+This fix undoes the incorrect change.

+[nix]: drop docs update (wouldn't apply)
