From 1d90b4e07dc1a2bdf3d65ac6f0bb6153610d3ff0 Mon Sep 17 00:00:00 2001 From: tb Date: Fri, 28 Jul 2023 10:17:21 +0000 Subject: [PATCH] Remove BUF_[a-z]* API This are a bunch of strange string handlers with NULL checks that make no real sense except to some devs who like to sprinkle them everywhere. Fortunately, nothing uses these anymore, so they can go. ok jsing --- lib/libcrypto/Makefile | 3 +- lib/libcrypto/Symbols.list | 6 --- lib/libcrypto/buffer/buf_str.c | 79 ---------------------------------- lib/libcrypto/buffer/buffer.h | 18 +------- 4 files changed, 2 insertions(+), 104 deletions(-) delete mode 100644 lib/libcrypto/buffer/buf_str.c diff --git a/lib/libcrypto/Makefile b/lib/libcrypto/Makefile index 6d9a6ca8587..a174cc1b204 100644 --- a/lib/libcrypto/Makefile +++ b/lib/libcrypto/Makefile @@ -1,4 +1,4 @@ -# $OpenBSD: Makefile,v 1.147 2023/07/28 10:02:11 tb Exp $ +# $OpenBSD: Makefile,v 1.148 2023/07/28 10:17:21 tb Exp $ LIB= crypto LIBREBUILD=y @@ -201,7 +201,6 @@ SRCS+= bn_word.c # buffer/ SRCS+= buf_err.c -SRCS+= buf_str.c SRCS+= buffer.c # bytestring/ diff --git a/lib/libcrypto/Symbols.list b/lib/libcrypto/Symbols.list index 94a22938fcf..2f081c1a4ca 100644 --- a/lib/libcrypto/Symbols.list +++ b/lib/libcrypto/Symbols.list @@ -495,12 +495,6 @@ BUF_MEM_free BUF_MEM_grow BUF_MEM_grow_clean BUF_MEM_new -BUF_memdup -BUF_reverse -BUF_strdup -BUF_strlcat -BUF_strlcpy -BUF_strndup CAST_cbc_encrypt CAST_cfb64_encrypt CAST_decrypt diff --git a/lib/libcrypto/buffer/buf_str.c b/lib/libcrypto/buffer/buf_str.c deleted file mode 100644 index 4ebc4717c83..00000000000 --- a/lib/libcrypto/buffer/buf_str.c +++ /dev/null @@ -1,79 +0,0 @@ -/* $OpenBSD: buf_str.c,v 1.11 2017/04/09 14:33:21 jsing Exp $ */ -/* - * Copyright (c) 2014 Bob Beck - * - * Permission to use, copy, modify, and distribute this software for any - * purpose with or without fee is hereby granted, provided that the above - * copyright notice and this permission notice appear in all copies. - * - * THE SOFTWARE IS PROVIDED "AS IS" AND THE AUTHOR DISCLAIMS ALL WARRANTIES - * WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF - * MERCHANTABILITY AND FITNESS.
