From ba1315d0fbe7fa43aa7481b5d6e92bd03b0152d5 Mon Sep 17 00:00:00 2001 From: Denis Vlasenko Date: Sat, 13 Sep 2008 14:59:38 +0000 Subject: modutils/*: rewrite by Timo Teras - a lot faster (linear algorithmic complexity, smaller memory foot print) - a lot smaller (the old code was overly complicated) - loading of aliases is now module-init-tools compliant - blacklisting is done correctly (-b option added) - module argument quoting done right - depmod now correctly generates modules.symbols and modules.alias add/remove: 16/21 grow/shrink: 4/6 up/down: 6930/-9316 Total: -2386 bytes text data bss dec hex filename 806039 592 6680 813311 c68ff busybox_old 803498 592 6676 810766 c5f0e busybox_unstripped --- modutils/modutils.h | 68 +++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 68 insertions(+) create mode 100644 modutils/modutils.h (limited to 'modutils/modutils.h') diff --git a/modutils/modutils.h b/modutils/modutils.h new file mode 100644 index 000000000..32ee18b06 --- /dev/null +++ b/modutils/modutils.h @@ -0,0 +1,68 @@ +/* + * Common modutils related functions for busybox + * + * Copyright (C) 2008 by Timo Teras + * + * Licensed under GPLv2 or later, see file LICENSE in this tarball for details. + */ + +#ifndef __MODUTILS_H__ +#define __MODUTILS_H__ + +#include "libbb.h" +#include + +#if __GNUC_PREREQ(4,1) +# pragma GCC visibility push(hidden) +#endif + +/* As defined in linux/include/linux/module.h */ +#define MODULE_NAME_LEN 64 + +const char *moderror(int err) FAST_FUNC; +llist_t *llist_find(llist_t *first, const char *str) FAST_FUNC; +void replace(char *s, char what, char with) FAST_FUNC; +char *replace_underscores(char *s) FAST_FUNC; +int string_to_llist(char *string, llist_t **llist, const char *delim) FAST_FUNC ; +char *filename2modname(const char *filename, char *modname) FAST_FUNC; +char *parse_cmdline_module_options(char **argv) FAST_FUNC; + +#define INSMOD_OPTS "vq" USE_FEATURE_2_4_MODULES("sLo:fkx") \ + USE_FEATURE_INSMOD_LOAD_MAP("m") +#define INSMOD_ARGS USE_FEATURE_2_4_MODULES(, &insmod_outputname) + +enum { + INSMOD_OPT_VERBOSE = 0x0001, + INSMOD_OPT_SILENT = 0x0002, + INSMOD_OPT_SYSLOG = 0x0004 * ENABLE_FEATURE_2_4_MODULES, + INSMOD_OPT_LOCK = 0x0008 * ENABLE_FEATURE_2_4_MODULES, + INSMOD_OPT_OUTPUTNAME = 0x0010 * ENABLE_FEATURE_2_4_MODULES, + INSMOD_OPT_FORCE = 0x0020 * ENABLE_FEATURE_2_4_MODULES, + INSMOD_OPT_KERNELD = 0x0040 * ENABLE_FEATURE_2_4_MODULES, + INSMOD_OPT_NO_EXPORT = 0x0080 * ENABLE_FEATURE_2_4_MODULES, + INSMOD_OPT_PRINT_MAP = 0x0100 * ENABLE_FEATURE_INSMOD_LOAD_MAP, +#if ENABLE_FEATURE_2_4_MODULES +#if ENABLE_FEATURE_INSMOD_LOAD_MAP + INSMOD_OPT_UNUSED = 0x0200, +#else /* ENABLE_FEATURE_INSMOD_LOAD_MAP */ + INSMOD_OPT_UNUSED = 0x0100 +#endif +#else /* ENABLE_FEATURE_2_4_MODULES */ + INSMOD_OPT_UNUSED = 0x0004 +#endif +}; + +int FAST_FUNC bb_init_module(const char *module, const char *options); +int FAST_FUNC bb_delete_module(const char *module, unsigned int flags); + +#if ENABLE_FEATURE_2_4_MODULES +extern char *insmod_outputname; + +int FAST_FUNC bb_init_module_24(const char *module, const char *options); +#endif + +#if __GNUC_PREREQ(4,1) +# pragma GCC visibility pop +#endif + +#endif -- cgit v1.2.3
