Subject: [PATCH 23/23] SAPI: fix number of handles for FlushContext
|
||
|
|
|
||
|
|
The lookup table for the number of command handles for
|
||
|
|
Tss2_Sys_FlushContext has the count set to 1, when in reality the
|
||
|
|
command takes no handles in the handle area but a handle as the input
|
||
|
|
parameter. This works currently because handles and parameters are just
|
||
|
|
concatenated and the parsing logic on the TPM just unpacks them, so in
|
||
|
|
this case, thet're in the same spot with the same value. This goes
|
||
|
|
unnoticed until you call Tss2_Sys_GetCpBuffer and the buffer is empty as
|
||
|
|
the logic things its a handle in the handle area and not a handle in the
|
||
|
|
parameter area.
