From 2fc61ce8a6a6c2ac8652b8cea33d57acd50681c2 Mon Sep 17 00:00:00 2001 From: Alexander Barton Date: Sat, 6 Jun 2015 22:19:47 +0200 Subject: [PATCH] Make setgroups(3) function optional For example, Interix is missing this function, which prevented ngIRCd to build on this platform. When setgroups(3) isn't available, a warning message is issued when ngIRCd starts up. --- configure.ng | 4 ++-- src/ngircd/ngircd.c | 5 +++++ 2 files changed, 7 insertions(+), 2 deletions(-) diff --git a/configure.ng b/configure.ng index bd40694f..34094a48 100644 --- a/configure.ng +++ b/configure.ng @@ -221,8 +221,8 @@ AC_CHECK_FUNCS([ \ # Optional functions AC_CHECK_FUNCS_ONCE([ arc4random arc4random_stir gai_strerror getnameinfo inet_aton \ - sigaction sigprocmask snprintf vsnprintf strdup strndup strlcpy strlcat \ - strtok_r unsetenv waitpid]) + setgroups sigaction sigprocmask snprintf strdup strlcat strlcpy \ + strndup strtok_r unsetenv vsnprintf waitpid]) WORKING_GETADDRINFO diff --git a/src/ngircd/ngircd.c b/src/ngircd/ngircd.c index 1b20597d..0e8acb54 100644 --- a/src/ngircd/ngircd.c +++ b/src/ngircd/ngircd.c @@ -724,6 +724,7 @@ NGIRCd_Init(bool NGIRCd_NoDaemon) if (real_errno != EPERM) goto out; } +#ifdef HAVE_SETGROUPS if (setgroups(0, NULL) != 0) { real_errno = errno; Log(LOG_ERR, "Can't drop supplementary group IDs: %s!", @@ -731,6 +732,10 @@ NGIRCd_Init(bool NGIRCd_NoDaemon) if (real_errno != EPERM) goto out; } +#else + Log(LOG_WARNING, + "Can't drop supplementary group IDs: setgroups(3) missing!"); +#endif } #endif -- 2.39.2
