函数名称:he loader itself
函数原型:static int load_misc_binary(struct linux_binprm *bprm)
返回类型:int
参数:
类型 | 参数 | 名称 |
---|---|---|
struct linux_binprm * | bprm |
135 | struct file * interp_file = NULL |
137 | fd_binary等于负1 |
144 | read_lock( & entries_lock) |
145 | fmt等于Check if we support the binfmt* if we do, return the node, else NULL* locking is done in load_misc_binary |
148 | read_unlock( & entries_lock) |
154 | 如果interp_flags按位与BINPRM_FLAGS_PATH_INACCESSIBLE则转到:ret |
157 | 如果非 type, status, etc. 按位与MISC_FMT_PRESERVE_ARGV0的值则 |
163 | 如果 type, status, etc. 按位与MISC_FMT_OPEN_BINARY则 |
169 | fd_binary等于get_unused_fd_flags(0) |
170 | 如果fd_binary小于0则 |
174 | fd_install(fd_binary, file) |
178 | would_dump(bprm, file) |
180 | allow_write_access(file) |
181 | file = NULL |
185 | interp_data等于fd_binary |
187 | 否则 |
196 | argc自加 |
202 | argc自加 |
209 | 如果 type, status, etc. 按位与MISC_FMT_OPEN_FILE则 |
211 | 如果非是错误则deny_write_access(interp_file) |
213 | 否则 |
220 | file等于interp_file |
221 | 如果 type, status, etc. 按位与MISC_FMT_CREDENTIALS则 |
222 | pos等于0 |
228 | memset(buf, 0, sizeof(linux_binprm->buf) ) |
229 | retval等于kernel_read(file, buf, sizeof(linux_binprm->buf) , & pos) |
231 | 否则retval等于Fill the binprm structure from the inode.* Check permissions, then read the first BINPRM_BUF_SIZE bytes* This may be called multiple times for binary chains (scripts for example). |
241 | ret : |
243 | 返回:retval |
244 | error : |
245 | 如果fd_binary大于0则In contrast to sys_close(), this stub does not check whether the syscall* should or should not be restarted, but returns the raw error codes from* __close_fd(). |
247 | interp_flags等于0 |
248 | interp_data等于0 |
249 | 转到:ret |
