From: Andre Noll Date: Fri, 20 Jun 2008 08:44:16 +0000 (+0200) Subject: Move the uid-range parser to string.c. X-Git-Tag: v0.0.3~15 X-Git-Url: http://git.tue.mpg.de/?a=commitdiff_plain;h=9ca6c5e46bfbfeb6341a54703a21e25c15ef0f7e;p=adu.git Move the uid-range parser to string.c. This code will also be needed by the interactive mode. --- diff --git a/adu.c b/adu.c index 42d1b19..07248e9 100644 --- a/adu.c +++ b/adu.c @@ -166,61 +166,6 @@ static struct osl_column_description user_table_cols[] = { }, }; -static int check_uid_arg(const char *arg, uint32_t *uid) -{ - const uint32_t max = ~0U; - /* - * we need an 64-bit int for string -> uid conversion because strtoll() - * returns a signed value. - */ - int64_t val; - int ret = atoi64(arg, &val); - - if (ret < 0) - return ret; - if (val < 0 || val > max) - return -ERRNO_TO_ERROR(EINVAL); - *uid = val; - return 1; -} - -static int parse_uid_range(const char *orig_arg, struct uid_range *ur) -{ - int ret; - char *arg = adu_strdup(orig_arg), *p = strchr(arg, '-'); - - if (!p || p == arg) { /* -42 or 42 */ - ret = check_uid_arg(p? p + 1 : arg, &ur->high); - if (ret < 0) - goto out; - ur->low = p? 0 : ur->high; - ret = 1; - goto out; - } - /* 42- or 42-4711 */ - *p = '\0'; - p++; - ret = check_uid_arg(arg, &ur->low); - if (ret < 0) - goto out; - ur->high = ~0U; - if (*p) { /* 42-4711 */ - ret = check_uid_arg(p, &ur->high); - if (ret < 0) - goto out; - } - if (ur->low > ur->high) - ret = -ERRNO_TO_ERROR(EINVAL); -out: - if (ret < 0) - ERROR_LOG("bad uid option: %s\n", orig_arg); - else - INFO_LOG("admissible uid range: %u - %u\n", ur->low, - ur->high); - free(arg); - return ret; -} - /** * The log function. * diff --git a/string.c b/string.c index a0666d3..8b6ea5a 100644 --- a/string.c +++ b/string.c @@ -166,3 +166,59 @@ __must_check int atoi64(const char *str, int64_t *result) *result = tmp; return 1; } + +static int check_uid_arg(const char *arg, uint32_t *uid) +{ + const uint32_t max = ~0U; + /* + * we need an 64-bit int for string -> uid conversion because strtoll() + * returns a signed value. + */ + int64_t val; + int ret = atoi64(arg, &val); + + if (ret < 0) + return ret; + if (val < 0 || val > max) + return -ERRNO_TO_ERROR(EINVAL); + *uid = val; + return 1; +} + +int parse_uid_range(const char *orig_arg, struct uid_range *ur) +{ + int ret; + char *arg = adu_strdup(orig_arg), *p = strchr(arg, '-'); + + if (!p || p == arg) { /* -42 or 42 */ + ret = check_uid_arg(p? p + 1 : arg, &ur->high); + if (ret < 0) + goto out; + ur->low = p? 0 : ur->high; + ret = 1; + goto out; + } + /* 42- or 42-4711 */ + *p = '\0'; + p++; + ret = check_uid_arg(arg, &ur->low); + if (ret < 0) + goto out; + ur->high = ~0U; + if (*p) { /* 42-4711 */ + ret = check_uid_arg(p, &ur->high); + if (ret < 0) + goto out; + } + if (ur->low > ur->high) + ret = -ERRNO_TO_ERROR(EINVAL); +out: + if (ret < 0) + ERROR_LOG("bad uid option: %s\n", orig_arg); + else + INFO_LOG("admissible uid range: %u - %u\n", ur->low, + ur->high); + free(arg); + return ret; +} + diff --git a/string.h b/string.h index ebf3b17..d975178 100644 --- a/string.h +++ b/string.h @@ -12,3 +12,5 @@ __must_check __malloc void *adu_calloc(size_t size); __must_check __malloc char *adu_strdup(const char *s); __must_check __malloc __printf_1_2 char *make_message(const char *fmt, ...); __must_check int atoi64(const char *str, int64_t *result); +int parse_uid_range(const char *orig_arg, struct uid_range *ur); +
