|

|
|
* s/w module to access the RELA sections in the ELF image. These are used to
|
||
|
|
* apply the relocations applied by the module loader in reverse, so that we
|
||
|
|
* can reconstruct the image that was used to derive the HMAC used by the
|
||
|
|
* integrity check.
|
||
|
|
*
|
||
|
|
* The first .long of each entry will be populated by the module loader based
|
||
|
|
* on the actual placement of the respective RELA section in memory. The second
|
||
|
|
* .long carries the RELA entry count, and is populated by the host tool that
|
||
|
|
* also generates the HMAC of the contents of .text and .rodata.
