From b690bd0b83ffb6d29a1cd373635864bd1b086ac7 Mon Sep 17 00:00:00 2001 From: Klemens Nanni Date: Mon, 14 Jun 2021 21:37:07 +0000 Subject: [PATCH] OpenBSD: Simplify promise creation after seprintf() introduction Just truncate the initial promises back to the final ones after pledging for the first time, saving code and memory. Assign `ptr' in all initial `seprintf()' calls for consistency while here. --- chat.c | 9 ++++----- 1 file changed, 4 insertions(+), 5 deletions(-) diff --git a/chat.c b/chat.c index 2a64ee0..9332ca8 100644 --- a/chat.c +++ b/chat.c @@ -295,10 +295,9 @@ int main(int argc, char *argv[]) { if (logEnable) ptr = seprintf(ptr, end, " wpath cpath"); if (!self.restricted) ptr = seprintf(ptr, end, " proc exec"); - char *promisesFinal = strdup(promises); - if (!promisesFinal) err(EX_OSERR, "strdup"); + char *promisesInitial = ptr; - seprintf(ptr, end, " inet dns"); + ptr = seprintf(ptr, end, " inet dns"); int error = pledge(promises, NULL); if (error) err(EX_OSERR, "pledge"); #endif @@ -316,9 +315,9 @@ int main(int argc, char *argv[]) { int irc = ircConnect(bind, host, port); #ifdef __OpenBSD__ - error = pledge(promisesFinal, NULL); + *promisesInitial = '\0'; + error = pledge(promises, NULL); if (error) err(EX_OSERR, "pledge"); - free(promisesFinal); #endif if (pass) ircFormat("PASS :%s\r\n", pass);
