From e4631b48e17e63a3859456df639482063a0276fd Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Thu, 14 Jul 2016 12:23:39 +0200 Subject: sysusers: move various user credential validity checks to src/basic/ This way we can reuse them for validating User=/Group= settings in unit files (to be added in a later commit). Also, add some tests for them. --- src/sysusers/sysusers.c | 75 ------------------------------------------------- 1 file changed, 75 deletions(-) (limited to 'src/sysusers') diff --git a/src/sysusers/sysusers.c b/src/sysusers/sysusers.c index 787d68a009..5d72493725 100644 --- a/src/sysusers/sysusers.c +++ b/src/sysusers/sysusers.c @@ -1299,81 +1299,6 @@ static bool item_equal(Item *a, Item *b) { return true; } -static bool valid_user_group_name(const char *u) { - const char *i; - long sz; - - if (isempty(u)) - return false; - - if (!(u[0] >= 'a' && u[0] <= 'z') && - !(u[0] >= 'A' && u[0] <= 'Z') && - u[0] != '_') - return false; - - for (i = u+1; *i; i++) { - if (!(*i >= 'a' && *i <= 'z') && - !(*i >= 'A' && *i <= 'Z') && - !(*i >= '0' && *i <= '9') && - *i != '_' && - *i != '-') - return false; - } - - sz = sysconf(_SC_LOGIN_NAME_MAX); - assert_se(sz > 0); - - if ((size_t) (i-u) > (size_t) sz) - return false; - - if ((size_t) (i-u) > UT_NAMESIZE - 1) - return false; - - return true; -} - -static bool valid_gecos(const char *d) { - - if (!d) - return false; - - if (!utf8_is_valid(d)) - return false; - - if (string_has_cc(d, NULL)) - return false; - - /* Colons are used as field separators, and hence not OK */ - if (strchr(d, ':')) - return false; - - return true; -} - -static bool valid_home(const char *p) { - - if (isempty(p)) - return false; - - if (!utf8_is_valid(p)) - return false; - - if (string_has_cc(p, NULL)) - return false; - - if (!path_is_absolute(p)) - return false; - - if (!path_is_safe(p)) - return false; - - /* Colons are used as field separators, and hence not OK */ - if (strchr(p, ':')) - return false; - - return true; -} - static int parse_line(const char *fname, unsigned line, const char *buffer) { static const Specifier specifier_table[] = { -- cgit v1.2.3-54-g00ecf
