Another solution is to adopt the same cryptouser change in the kbuild tree, something like this: diff --git a/include/linux/crypto.h b/include/linux/crypto.h index cc2425b..c0b0cf3 100644 --- a/include/linux/crypto.h +++ b/include/linux/crypto.h @@ -24,7 +24,6 @@ #include <linux/slab.h> #include <linux/string.h> #include <linux/uaccess.h> -#include <uapi/linux/crypto.h> /* * Autoloaded crypto modules should only use a prefixed name to avoid allowing @@ -124,6 +123,7 @@ /* * Miscellaneous stuff. */ +#define CRYPTO_MAX_ALG_NAME 64 /* * The macro CRYPTO_MINALIGN_ATTR (along with the void * type in the actual diff --git a/include/uapi/linux/crypto.h b/include/uapi/linux/crypto.h deleted file mode 100644 index e342c5a..0000000 --- a/include/uapi/linux/crypto.h +++ /dev/null @@ -1,14 +0,0 @@ -/* - * Copyright (c) 2017 Nicolas Dichtel <nicolas.dichtel@xxxxxxxxx> - * - * This program is free software; you can redistribute it and/or modify - * it under the terms of the GNU General Public License version 2 - * as published by the Free Software Foundation. - */ - -#ifndef _UAPI_CRYPTO_H -#define _UAPI_CRYPTO_H - -#define CRYPTO_MAX_ALG_NAME 64 - -#endif /* _UAPI_CRYPTO_H */ diff --git a/include/uapi/linux/cryptouser.h b/include/uapi/linux/cryptouser.h index 751e7da..d041fbb 100644 --- a/include/uapi/linux/cryptouser.h +++ b/include/uapi/linux/cryptouser.h @@ -21,7 +21,6 @@ #ifndef _UAPI_CRYPTOUSER_H #define _UAPI_CRYPTOUSER_H -#include <linux/crypto.h> #include <linux/types.h> /* Netlink configuration messages. */ @@ -37,7 +36,7 @@ enum { #define CRYPTO_MSG_MAX (__CRYPTO_MSG_MAX - 1) #define CRYPTO_NR_MSGTYPES (CRYPTO_MSG_MAX + 1 - CRYPTO_MSG_BASE) -#define CRYPTO_MAX_NAME CRYPTO_MAX_ALG_NAME +#define CRYPTO_MAX_NAME 64 /* Netlink message attributes. */ enum crypto_attr_type_t { @@ -59,9 +58,9 @@ enum crypto_attr_type_t { }; struct crypto_user_alg { - char cru_name[CRYPTO_MAX_ALG_NAME]; - char cru_driver_name[CRYPTO_MAX_ALG_NAME]; - char cru_module_name[CRYPTO_MAX_ALG_NAME]; + char cru_name[CRYPTO_MAX_NAME]; + char cru_driver_name[CRYPTO_MAX_NAME]; + char cru_module_name[CRYPTO_MAX_NAME]; __u32 cru_type; __u32 cru_mask; __u32 cru_refcnt; @@ -79,7 +78,7 @@ struct crypto_report_hash { }; struct crypto_report_cipher { - char type[CRYPTO_MAX_ALG_NAME]; + char type[CRYPTO_MAX_NAME]; unsigned int blocksize; unsigned int min_keysize; unsigned int max_keysize; -- Email: Herbert Xu <herbert@xxxxxxxxxxxxxxxxxxx> Home Page: http://gondor.apana.org.au/~herbert/ PGP Key: http://gondor.apana.org.au/~herbert/pubkey.txt -- To unsubscribe from this list: send the line "unsubscribe linux-next" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
