It identify self as version 1.3.2-XU(014). Unfortunately, version string is defined as three non-negative integers separated by periods followed by optional alphanumeric string in parenthesis. 1.3.2-XU(014) doesn't follow the rule.
As a result, it's not possible to use $SWVER in version-style conditional expressions. Only string-style expressions are working. All version-style conditionals evaluate to FALSE, even the ( $SWVER eq $SWVER ).
Well, it's just another firmware bug. I'm sure it will be solved in a future firmware version. I'm not living in the country with restricted access to cryptography, so no reason to use XU image.
Despite of it, there is issue related to it. I assume that bug mentioned above will be patched and -XU will be ignored in SWVER string. So 1.3.2(014) will equal to 1.3.2-XU(014).
According Lance Harper's notice elsewhere, future devices will be shipped with XU image. Imagine someone who is using conditional expression "if device firmware less than some selected minimum then upgrade". It can be done using trivial conditional expression ( $SWVER lt <a minimal acceptable version> ). I advance, such person is using SRTP. So XU image needs to be updated to non-XU version even it's newer than required minimum.
I assume we need something like "if SWVER less than minimum OR image is XU style then upgrade". So, how I can test the device's current firmware is the XU-style image or not ? And how I can do "OR" in conditional expression?
