Subject: Re: [PATCH v2 02/10] sandbox: tpm: Tidy up reading and writing of device state
Date: Sat, 24 Jul 2021 14:12:09 -0700 [thread overview]
Message-ID: <CAPnjgZ2yyW0-wcRdMFPAfsozXmbxNfC23G=R0HCi9mN0j-i7yQ@mail.gmail.com> (raw)
In-Reply-To: <20210718201806.761202-3-sjg@chromium.org>
At present this code assumes that the TPM data has been read but this may
not be the case. Refactor the code to use a separate pointer so we know
the current state of the data.
Add error checking for the data size.
