earlier versions fail to generate .reginfo and hence gprel relocations

@node Verifiers framework
@chapter Verifiers framework
To register your own verifier call @samp{grub_verifier_register} with a
structure pointing to your functions.
The interface is inspired by hash interface with @samp{init}/@samp{write}/@samp{fini}.
There are eesntially 2 ways of using it: hashing and whole-file verification:
With hashing approach:
During @samp{init} you decide whether you want to check given file and init context.
In @samp{write} you update you hashing state.
In @samp{fini} you check that hash matches the expected value/passes some check/...
With whole-file verification:
During @samp{init} you decide whether you want to check given file and init context.
In @samp{write} you verify file and return error if it fails.
You don't have @samp{fini}.
Additional @samp{verify_string} receives various strings like kernel parameters to
verify. Returning no error means successful verification and an error stops the current
action.
Detailed description of API:
Every time a file is opened your @samp{init} function is called with file descriptor
and file type. Your function can have following outcomes:
@itemize
@item returning no error and setting @samp{*flags} to @samp{GRUB_VERIFY_FLAGS_SKIP_VERIFICATION}.
In this case your verifier will not be called anymore and your verifier is considered
to have skipped verification
@item returning error. Then opening of the fail will fail due to failed verification.
@item returning no error and not setting @samp{*flags} to @samp{GRUB_VERIFY_FLAGS_SKIP_VERIFICATION}
In this case verification is done as described in following section
@end itemize
In the third case your @samp{write} will be called with chunks of file. If you need the whole file in a single
chunk then during @samp{init} set bit @samp{GRUB_VERIFY_FLAGS_SINGLE_CHUNK} in @samp{*flags}.
During @samp{init} you may set @samp{*context} if you need additional context. At every iteration you may return
an error and the the file will be considered as having failed the verification. If you return no error then
verification continues.
Optionally at the end of the file @samp{fini} if it exists is called with just the context. If you return
no error during any of @samp{init}, @samp{write} and @samp{fini} then the file is considered as having
succeded verification.
