Subject: OTA does not work with IMA due to xattr not supported by zip
Date: Tue, 8 Jan 2019 06:56:37 +0530	[thread overview]
Message-ID: <CALUj-gsiY+_K_PM2kAXvVFU+wntq6tQaqUk+BVzwA3o-7nhCPw@mail.gmail.com> (raw)

Hi Team,

Android and android recovery based implementation for Linux, generates
ota package which is a zipped archive.

I observed that xattr gets dropped when creating zip archive and
therefore after OTA system will not boot if IMA_APPRAISE_SIGNED_INIT
is used.

This essentially means that IMA may not be used in commercial products
requiring OTA or I missed something or there is a workaround to such
problem.

Regards,
Rishi
