My guess is that the author who added +the calls thought that listen() is a blocking call, which is not the +case. The only thing we need to satisfy is that close() is called +before accept, because that is a blocking call. That's all that is +needed to fix the bug that was fixed by adding the close() calls. + +Resolves: rhbz#1666380 +--- + standalone.c | 6 +++--- + 1 file changed, 3 insertions(+), 3 deletions(-) + +diff --git a/standalone.c b/standalone.c +index 3f35e9e..b358ca1 100644 +--- a/standalone.c ++++ b/standalone.c +@@ -152,15 +152,15 @@ vsf_standalone_main(void) + vsf_sysutil_kill(vsf_sysutil_getppid(), kVSFSysUtilSigUSR1); + } + } +- vsf_sysutil_close(0); +- vsf_sysutil_close(1); +- vsf_sysutil_close(2); + retval = vsf_sysutil_listen(listen_sock, VSFTP_LISTEN_BACKLOG); + if (vsf_sysutil_retval_is_error(retval)) + { + die("could not listen"); + } + vsf_sysutil_sockaddr_alloc(&p_accept_addr); ++ vsf_sysutil_close(0); ++ vsf_sysutil_close(1); ++ vsf_sysutil_close(2); + while (1) + { + struct vsf_client_launch child_info; +-- +2.20.1 + |
