Subject: [PATCH] netscaler: add more checks to make sure the record is within
the page.
Whie we're at it, restructure some other checks to test-before-casting -
it's OK to test afterwards, but testing before makes it follow the
pattern used elsewhere.
Fixes #19081.

From da017472e69453011ea28571f192cbc79cba7f5c Mon Sep 17 00:00:00 2001
From: Guy Harris <gharris@sonic.net>

Subject: [PATCH] vms: fix the search for the packet length field.
The packet length field is of the form
Total Length = DDD = ^xXXX
where "DDD" is the length in decimal and "XXX" is the length in
hexadecimal.
Search for "length ". not just "Length", as we skip past "Length ", not
just "Length", so if we assume we found "Length " but only found
"Length", we'd skip past the end of the string.
While we're at it, fail if we don't find a length field, rather than
just blithely acting as if the packet length were zero.
Fixes #19083.
