From dbed71416332d24e4e9ba26dcf90cd86a93c06f1 Mon Sep 17 00:00:00 2001 From: David Howells Date: Fri, 1 Nov 2013 15:11:14 +0000 Subject: KEYS: The RSA public key algorithm needs to select MPILIB The RSA public key algorithm needs to select MPILIB directly in Kconfig as the 'select' directive is not recursive and is thus MPILIB is not enabled by selecting MPILIB_EXTRA. Without this, the following errors can occur: crypto/built-in.o: In function `RSA_verify_signature': rsa.c:(.text+0x1d347): undefined reference to `mpi_get_nbits' rsa.c:(.text+0x1d354): undefined reference to `mpi_get_nbits' rsa.c:(.text+0x1d36e): undefined reference to `mpi_cmp_ui' rsa.c:(.text+0x1d382): undefined reference to `mpi_cmp' rsa.c:(.text+0x1d391): undefined reference to `mpi_alloc' rsa.c:(.text+0x1d3b0): undefined reference to `mpi_powm' rsa.c:(.text+0x1d3c3): undefined reference to `mpi_free' rsa.c:(.text+0x1d3d8): undefined reference to `mpi_get_buffer' rsa.c:(.text+0x1d4d4): undefined reference to `mpi_free' rsa.c:(.text+0x1d503): undefined reference to `mpi_get_nbits' Reported-by: Randy Dunlap Signed-off-by: David Howells Acked-by: Randy Dunlap --- crypto/asymmetric_keys/Kconfig | 1 + 1 file changed, 1 insertion(+) (limited to 'crypto') diff --git a/crypto/asymmetric_keys/Kconfig b/crypto/asymmetric_keys/Kconfig index 82e7d6b0c276..03a6eb95ab50 100644 --- a/crypto/asymmetric_keys/Kconfig +++ b/crypto/asymmetric_keys/Kconfig @@ -23,6 +23,7 @@ config ASYMMETRIC_PUBLIC_KEY_SUBTYPE config PUBLIC_KEY_ALGO_RSA tristate "RSA public-key algorithm" select MPILIB_EXTRA + select MPILIB help This option enables support for the RSA algorithm (PKCS#1, RFC3447). -- cgit v1.2.3
