+autofs-5.1.6 - fix autofs mount options construction
+
+From: Ian Kent <raven@themaw.net>
+
+There's an off by one length error in the autofs mount options
+construction.
+
+Consolidate the options construction into make_options_string() and
+use snprintf() to verify the options length calculation is correct.

+autofs-5.1.6 - fix quoted string length calc in expandsunent()
+
+From: Ian Kent <raven@themaw.net>
+
+The expandsunent() function in modules/parse_sun.c fails to properly
+handle the ending " in a quoted string causing the length calculation
+to not account for the ending quote and also doesn't properly account
+for the remainder of the string being expanded.
+
+Also, when called again (after being called to get the length) the
+allocated buffer is too small leading to out of bounds accesses.

+
+From: Ian Kent <raven@themaw.net>
+
+The getaddrinfo() call may have become more fussy about initialization
+of the passed in struct addrinfo that receives the results.
+
+It's good practice to initialize it prior to the gataddrinfo() call just
+in case.
