stunnel: symbol lookup error: stunnel undefined symbol: X509_check_host
by Ryan McLeod 20 Oct '15

20 Oct '15

Hello. I get the error in the subject on 64bit Ubuntu and Debian system (32bit is fine). I've installed from source: -openssl-1.0.2.d -stunnel-5.24 When first install stunnel, it complained about not being able to find an ssl library during the configure stage and said to reinstall openssl with -fPIC. I did that using the following line: CFLAG=-fPIC ./config shared Once I did that, stunnel installed just fine. But when I run stunnel, I get the error in the subject. I tried reinstalling stunnel with a configure option: --with-ssl=/usr/local/ssl/. But no change. Any suggestions would be great. Thanks. Ryan

Windows Mobile 6.5
by Jeffrey McCain 19 Oct '15

Hello, Does Anyone know if the makece.bat for ARM actually functions anymore? I'd like to build the latest possible version of stunnel for a client that uses Window Mobile 6.5, but not if I have to go back to stunnel version 4.15, which appears to be the last time someone built binaries for it... Thanks! Jeff.

Dear subscribers I am new to this so I dont know if this is just wrong configuration (that does not trigger an error message). Searching on the web for the following problem shows someone reporting sth similar on a Linux machine. I am using the newest version of stunnel (5.24) on Windows 7 and there is an stunnel thread starting that takes 100% of one core forever. I have attached a ProcMon trace with activated Registry/Filesystem/Network/Process events. The thread starts at 22:03:55 (which is 30 seconds after stunnel-start and at a time at which I did not use stunnel). The events after that follow that event are my pressing exit. Attachements: stunnel config, procMon-trace Thank you!

Question about "forground = yes" and "output = FILE" combined options
by Michael Gebis 16 Oct '15

16 Oct '15

Hello. I have a question about the combination of the "foreground = yes" option combined with the "output = FILE" option. The man page says this: foreground = yes | no (Unix only) foreground mode Stay in foreground (don’t fork) and log to stderr instead of via syslog (unless output is specified). This implies that if you set both "foreground = yes" and "output = FILE", the log messages will not be sent to stderr and will instead be sent to the log file only. We'd like this behavior--it makes it easier for our scripts to distinguish startup errors parsing the config file (which are sent to stderr, since the log file isn't configured yet) vs. normal operation after the config file is parsed and the log file is established. However, it appears that if you specify "foreground = yes" and "output = FILE", log messages will go to *both* stderr and the output file. I guess I'm asking: is the documentation in conflict with the behavior, and if so, which is correct? It's possible I'm just misreading the man page. But in any case, here is a simple patch which changes the behavior to match our reading of the man page. It is against stunnel-5.22 but I believe it should be applicable to later versions as well. Thank you, Michael diff -ru stunnel-5.22.orig/src/log.c stunnel-5.22-foreground-outfile/src/log.c --- stunnel-5.22.orig/src/log.c 2015-06-16 06:16:35.000000000 -0700 +++ stunnel-5.22-foreground-outfile/src/log.c 2015-10-14 11:54:58.998254974 -0700 @@ -243,7 +243,8 @@ level<=opt->log_level #else (level<=opt->log_level && - global_options.option.foreground) + global_options.option.foreground && + !outfile) #endif ) ui_new_log(line);

Can stunnel do this and if so, how?
by Jason Lacoss-Arnold 15 Oct '15

15 Oct '15

I have a client and a server where the client isn't very good and the server requires a MASSL (Mutual Auth SSL aka client certificate authenticated) connection. I need to get one of two things to work. Either: 1) The client makes a non-SSL connection to stunnel on the local machine which then performs a MASSL connection to the server using a client certificate or 2) The client makes a plain SSL connection to stunnel on the local machine which then performs a MASSL connection to the server using a client certificate. Can stunnel be used in this manner? If so, would someone please give me some hints on configuration? For extra credit, it would be awesome if the client private key were stored in a pkcs11 device (HSM). Thank you, --Jason

Unable to authenticate with Outlook.com servers (SMTP)

Greetings, Running stunnel 5.25 latest beta (2015-10-15), but also had the same issues on 5.24 final. My config file looks like this: debug = debug output = xxxxx client = yes cert = stunnel.pem [outlook-smtp] accept = 127.0.0.1:25 connect = smtp-mail.outlook.com:587 protocol = smtp ;protocolUsername = xxxx ;protocolPassword = xxxx CAfile = ca-certs.pem checkHost = smtp-mail.outlook.com OCSPaia = yes verify = 2 I am testing functionality to make sure that I am able to send mail with my Outlook.com address. I currently have User/Pass field commented out, but I've tried with them not commented out, and the actual values instead of "xxxx" (the app I'm using has fields for username and password).

prng_init failure
by Philip Craig 15 Oct '15

15 Oct '15

prng_init() is failing in 5.24 when cross-compiling with openssl due to a combination of two reasons: 1. The --with-random configure option is not supported when cross compiling. 2. The hardcoded /dev/urandom is no longer used if OPENSSL_NO_EGD is not defined. The following patch reverts the behaviour to how it was in 5.23, but probably the --with-random configure option should be supported too. --- stunnel-5.25.orig/src/ssl.c +++ stunnel-5.25/src/ssl.c @@ -207,7 +207,8 @@ NOEXPORT int prng_init(GLOBAL_OPTIONS *g return 0; /* success */ } s_log(LOG_DEBUG, "RAND_screen failed to sufficiently seed PRNG"); -#elif !defined(OPENSSL_NO_EGD) +#else +#ifndef OPENSSL_NO_EGD if(global->egd_sock) { if((bytes=RAND_egd(global->egd_sock))==-1) { s_log(LOG_WARNING, "EGD Socket %s failed", global->egd_sock); @@ -220,7 +221,7 @@ NOEXPORT int prng_init(GLOBAL_OPTIONS *g so no need to check if seeded sufficiently */ } } -#else +#endif /* try the good-old default /dev/urandom, if available */ totbytes+=add_rand_file(global, "/dev/urandom"); if(RAND_status())

[PATCH] only use aysnc-signal-safe functions after fork
by Philip Craig 15 Oct '15

15 Oct '15

POSIX requires that multi-threaded processes only use async-signal-safe functions after calling fork(). For more info on the problems this avoids, see the rationale at: http://pubs.opengroup.org/onlinepubs/9699919799/functions/pthread_atfork.ht… The specific problem this patch solves is that, when there are multiple simultaneous requests, stunnel is often hanging on a futex syscall when a child process calls free as a result of tls_alloc(). This problem is experienced when using uClibc. I haven't tested, but I believe the malloc implementation in glibc does not have this problem. --- stunnel-5.24.orig/src/client.c +++ stunnel-5.24/src/client.c @@ -1100,6 +1100,8 @@ NOEXPORT SOCKET connect_local(CLI *c) { NOEXPORT SOCKET connect_local(CLI *c) { /* spawn local process */ char *name, host[40], port[6]; + char *env[10]; + int i, envc; int fd[2], pid; X509 *peer_cert; #ifdef HAVE_PTHREAD_SIGMASK @@ -1115,19 +1117,55 @@ NOEXPORT SOCKET connect_local(CLI *c) { } else if(make_sockets(fd)) longjmp(c->err, 1); + set_nonblock(fd[1], 0); /* switch back to blocking mode */ + + envc = 0; + + if(!getnameinfo(&c->peer_addr.sa, c->peer_addr_len, + host, 40, port, 6, NI_NUMERICHOST|NI_NUMERICSERV)) { + /* just don't set these variables if getnameinfo() fails */ + env[envc++] = str_printf("REMOTE_HOST=%s", host); + env[envc++] = str_printf("REMOTE_PORT=%s", port); + if(c->opt->option.transparent_src) { +#ifndef LIBDIR +#define LIBDIR "." +#endif +#ifdef MACH64 + env[envc++] = str_dup("LD_PRELOAD_32=" LIBDIR "/libstunnel.so"); + env[envc++] = str_dup("LD_PRELOAD_64=" LIBDIR "/" MACH64 "/libstunnel.so"); +#elif __osf /* for Tru64 _RLD_LIST is used instead */ + env[envc++] = str_dup("_RLD_LIST=" LIBDIR "/libstunnel.so:DEFAULT"); +#else + env[envc++] = str_dup("LD_PRELOAD=" LIBDIR "/libstunnel.so"); +#endif + } + } + + if(c->ssl) { + peer_cert=SSL_get_peer_certificate(c->ssl); + if(peer_cert) { + name=X509_NAME2text(X509_get_subject_name(peer_cert)); + env[envc++] = str_printf("SSL_CLIENT_DN=%s", name); + name=X509_NAME2text(X509_get_issuer_name(peer_cert)); + env[envc++] = str_printf("SSL_CLIENT_I_DN=%s", name); + X509_free(peer_cert); + } + } + + env[envc] = NULL; pid=fork(); c->pid=(unsigned long)pid; switch(pid) { case -1: /* error */ + for (i = 0; i < envc; i++) + str_free(env[i]); closesocket(fd[0]); closesocket(fd[1]); ioerror("fork"); longjmp(c->err, 1); case 0: /* child */ - tls_alloc(NULL, c->tls, NULL); /* reuse thread-local storage */ closesocket(fd[0]); - set_nonblock(fd[1], 0); /* switch back to blocking mode */ /* dup2() does not copy FD_CLOEXEC flag */ dup2(fd[1], 0); dup2(fd[1], 1); @@ -1135,36 +1173,6 @@ NOEXPORT SOCKET connect_local(CLI *c) { dup2(fd[1], 2); closesocket(fd[1]); /* not really needed due to FD_CLOEXEC */ - if(!getnameinfo(&c->peer_addr.sa, c->peer_addr_len, - host, 40, port, 6, NI_NUMERICHOST|NI_NUMERICSERV)) { - /* just don't set these variables if getnameinfo() fails */ - putenv(str_printf("REMOTE_HOST=%s", host)); - putenv(str_printf("REMOTE_PORT=%s", port)); - if(c->opt->option.transparent_src) { -#ifndef LIBDIR -#define LIBDIR "." -#endif -#ifdef MACH64 - putenv("LD_PRELOAD_32=" LIBDIR "/libstunnel.so"); - putenv("LD_PRELOAD_64=" LIBDIR "/" MACH64 "/libstunnel.so"); -#elif __osf /* for Tru64 _RLD_LIST is used instead */ - putenv("_RLD_LIST=" LIBDIR "/libstunnel.so:DEFAULT"); -#else - putenv("LD_PRELOAD=" LIBDIR "/libstunnel.so"); -#endif - } - } - - if(c->ssl) { - peer_cert=SSL_get_peer_certificate(c->ssl); - if(peer_cert) { - name=X509_NAME2text(X509_get_subject_name(peer_cert)); - putenv(str_printf("SSL_CLIENT_DN=%s", name)); - name=X509_NAME2text(X509_get_issuer_name(peer_cert)); - putenv(str_printf("SSL_CLIENT_I_DN=%s", name)); - X509_free(peer_cert); - } - } #ifdef HAVE_PTHREAD_SIGMASK sigemptyset(&newmask); sigprocmask(SIG_SETMASK, &newmask, NULL); @@ -1176,11 +1184,13 @@ NOEXPORT SOCKET connect_local(CLI *c) { signal(SIGTERM, SIG_DFL); signal(SIGQUIT, SIG_DFL); signal(SIGINT, SIG_DFL); - execvp(c->opt->exec_name, c->opt->exec_args); + execve(c->opt->exec_name, c->opt->exec_args, env); ioerror(c->opt->exec_name); /* execvp failed */ _exit(1); default: /* parent */ s_log(LOG_INFO, "Local mode child started (PID=%lu)", c->pid); + for (i = 0; i < envc; i++) + str_free(env[i]); closesocket(fd[1]); return fd[0]; }
