2013-06-12lib/mpi/mpicoder.c: looping issue, need stop when equal to zero, found by ↵Chen Gang1-1/+1
'EXTRA_FLAGS=-W'. 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 <[email protected]> Cc: Rusty Russell <[email protected]> Cc: David Howells <[email protected]> Cc: James Morris <[email protected]> Cc: Andy Shevchenko <[email protected]> Acked-by: David Howells <[email protected]> Signed-off-by: Andrew Morton <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>

2012-10-08MPILIB: Provide a function to read raw data into an MPIDavid Howells1-0/+55
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.

2012-05-26Remove unused code from MPI libraryDmitry Kasatkin1-75/+0
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.

2012-02-02lib/mpi: removed unused functionsDmitry Kasatkin1-88/+0
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.

2011-11-09crypto: GnuPG based MPI lib - source files (part 1)Dmitry Kasatkin1-0/+365
Adds the multi-precision-integer maths library which was originally taken from GnuPG and ported to the kernel by (among others) David Howells. This version is taken from Fedora kernel 2.6.32-71.14.1.el6. The difference is that checkpatch reported errors and warnings have been fixed. This library is used to implemenet RSA digital signature verification used in IMA/EVM integrity protection subsystem. Due to patch size limitation, the patch is divided into 4 parts.
