From 9c5adf94cc6e41d0a7a5a770c3d45ee014532889 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Pavel=20B=C5=99ezina?= Date: Mon, 2 Sep 2013 15:15:59 +0200 Subject: [PATCH 4/8] util: add find_subdomain_by_sid() This function takes domain SID (doesn't have the last component) or object SID (have all components) and returns subdomain. The subdomain is found by comparing domain->domainid with the SID. E.g. domain SID: S-1-5-21-3940105347-3434501867-2690409756 object SID: S-1-5-21-3940105347-3434501867-2690409756-513 Resolves: https://fedorahosted.org/sssd/ticket/2034 --- src/util/domain_info_utils.c | 33 +++++++++++++++++++++++++++++++++ src/util/util.h | 2 ++ 2 files changed, 35 insertions(+) diff --git a/src/util/domain_info_utils.c b/src/util/domain_info_utils.c index 8b03e9a53fad8614ab0dccf14dceb30232ad84d4..f9d9057a811f3e08c451d7f6b44bc14202559962 100644 --- a/src/util/domain_info_utils.c +++ b/src/util/domain_info_utils.c @@ -95,6 +95,39 @@ struct sss_domain_info *find_subdomain_by_name(struct sss_domain_info *domain, return NULL; } +struct sss_domain_info *find_subdomain_by_sid(struct sss_domain_info *domain, + const char *sid) +{ + struct sss_domain_info *dom = domain; + size_t sid_len = strlen(sid); + size_t dom_sid_len; + + while (dom && dom->disabled) { + dom = get_next_domain(dom, true); + } + + while (dom) { + dom_sid_len = strlen(dom->domain_id); + + if (strncasecmp(dom->domain_id, sid, dom_sid_len) == 0) { + if (dom_sid_len == sid_len) { + /* sid is domain sid */ + return dom; + } + + /* sid is object sid, check if domain sid is align with + * sid first subauthority component */ + if (sid[dom_sid_len] == '-') { + return dom; + } + } + + dom = get_next_domain(dom, true); + } + + return NULL; +} + struct sss_domain_info *new_subdomain(TALLOC_CTX *mem_ctx, struct sss_domain_info *parent, const char *name, diff --git a/src/util/util.h b/src/util/util.h index c2c31f5d50e86315a3e751daf49cf594550bc7c6..2a77df1d811afbf66ae03d9cc1891f66e8e5a0ec 100644 --- a/src/util/util.h +++ b/src/util/util.h @@ -539,6 +539,8 @@ struct sss_domain_info *get_next_domain(struct sss_domain_info *domain, struct sss_domain_info *find_subdomain_by_name(struct sss_domain_info *domain, const char *name, bool match_any); +struct sss_domain_info *find_subdomain_by_sid(struct sss_domain_info *domain, + const char *sid); bool subdomain_enumerates(struct sss_domain_info *parent, const char *sd_name); -- 1.7.11.7
