MPI: Fix mpi_read_buffer

2015-08-25T13:13:16Z

Change mpi_read_buffer to return a number without leading zeros so that mpi_read_buffer and mpi_get_buffer return the same thing. Signed-off-by: Tadeusz Struk Signed-off-by: Herbert Xu

MPILIB: add mpi_read_buf() and mpi_get_size() helpers

2015-06-16T06:35:06Z

Added a mpi_read_buf() helper function to export MPI to a buf provided by the user, and a mpi_get_size() helper, that tells the user how big the buf is. Changed mpi_free to use kzfree instead of kfree because it is used to free crypto keys. Signed-off-by: Tadeusz Struk Signed-off-by: Herbert Xu

lib/mpi/mpicoder.c: looping issue, need stop when equal to zero, found by 'EXTRA_FLAGS=-W'.

2013-06-12T23:29:44Z

For 'while' looping, need stop when 'nbytes == 0', or will cause issue. ('nbytes' is size_t which is always bigger or equal than zero). The related warning: (with EXTRA_CFLAGS=-W) lib/mpi/mpicoder.c:40:2: warning: comparison of unsigned expression >= 0 is always true [-Wtype-limits] Signed-off-by: Chen Gang Cc: Rusty Russell Cc: David Howells Cc: James Morris Cc: Andy Shevchenko Acked-by: David Howells Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

MPILIB: Provide a function to read raw data into an MPI

2012-10-08T03:20:21Z

Provide a function to read raw data of a predetermined size into an MPI rather than expecting the size to be encoded within the data. The data is assumed to represent an unsigned integer, and the resulting MPI will be positive. The function looks like this: MPI mpi_read_raw_data(const void *, size_t); This is useful for reading ASN.1 integer primitives where the length is encoded in the ASN.1 metadata.

Remove unused code from MPI library

2012-05-26T01:51:03Z

MPI library is used by RSA verification implementation. Few files contains functions which are never called. James Morris has asked to remove all of them. Signed-off-by: Dmitry Kasatkin Requested-by: James Morris Signed-off-by: James Morris

lib/mpi: removed unused functions

2012-02-01T13:23:14Z

do_encode_md() and mpi_get_keyid() are not parts of mpi library. They were used early versions of gnupg and in digsig project, but they are not used neither here nor there anymore. Signed-off-by: Dmitry Kasatkin Reviewed-by: Tetsuo Handa Signed-off-by: James Morris
