Compilation problem

Hi everyone I try to compile stunnel, but it fails. Actually, it tells me about a parse error inside signal.h, and i think it's a falsePositive. The configure works great and nothing look strange inside the configure.log. I also tried to googled those errors, but didn't find any clues. My server is a sunOS 10 and the src were taken from http://www.stunnel.org/download/stunnel/src/stunnel-4.26.tar.gz My version of openssl : OpenSSL 0.9.7.d Here are the errors, after the make command : /stunnel-4.26 root# make Making all in src make[1]: Entering directory `/root/syslogNG/stunnel-4.26/src' if gcc -DPACKAGE_NAME=\"stunnel\" -DPACKAGE_TARNAME=\"stunnel\" -DPACKAGE_VERSION=\"4.26\" -DPACKAGE_STRING=\"stunnel\ 4.26\" -DPACKAGE_BUGREPORT=\"\" -DPACKAGE=\"stunnel\" -DVERSION=\"4.26\" -DHOST=\"i386-pc-solaris2.10\" -DCPU_I386=1 -DVENDOR_PC=1 -DOS_SOLARIS2_10=1 -DSTDC_HEADERS=1 -DHAVE_SYS_TYPES_H=1 -DHAVE_SYS_STAT_H=1 -DHAVE_STDLIB_H=1 -DHAVE_STRING_H=1 -DHAVE_MEMORY_H=1 -DHAVE_STRINGS_H=1 -DHAVE_INTTYPES_H=1 -DHAVE_STDINT_H=1 -DHAVE_UNISTD_H=1 -DHAVE_DLFCN_H=1 -DSIZEOF_UNSIGNED_CHAR=1 -DSIZEOF_UNSIGNED_SHORT=2 -DSIZEOF_UNSIGNED_INT=4 -DSIZEOF_UNSIGNED_LONG=4 -DHAVE_DEV_PTMX=1 -DRANDOM_FILE=\"/dev/urandom\" -DHAVE_UCONTEXT_H=1 -DHAVE_PTHREAD_H=1 -DHAVE_SYS_SELECT_H=1 -DHAVE_POLL_H=1 -DHAVE_SYS_POLL_H=1 -DHAVE_SYS_IOCTL_H=1 -DHAVE_SYS_FILIO_H=1 -DHAVE_STROPTS_H=1 -DHAVE_GRP_H=1 -DHAVE_UNISTD_H=1 -DHAVE_SYS_RESOURCE_H=1 -DHAVE_SYS_SOCKET_H=1 -DHAVE_LIBSOCKET=1 -DHAVE_LIBDL=1 -DHAVE_LIBZ=1 -DHAVE_LIBPTHREAD=1 -DUSE_PTHREAD=1 -DHAVE_SNPRINTF=1 -DHAVE_VSNPRINTF=1 -DHAVE_WAITPID=1 -DHAVE_WAIT4=1 -DHAVE_SETSID=1 -DHAVE_SETGROUPS=1 -DHAVE_CHROOT=1 -DHAVE_SYSCONF=1 -DHAVE_GETRLIMIT=1 -DHAVE_PTHREAD_SIGMASK=1 -DHAVE_LOCALTIME_R=1 -DHAVE_GETCONTEXT=1 -DHAVE_POLL=1 -DHAVE_ENDHOSTENT=1 -DHAVE_GETNAMEINFO=1 -DHAVE_GETADDRINFO=1 -DHAVE_OPENSSL=1 -Dssldir=\"/usr/local/ssl\" -DHAVE_OSSL_ENGINE_H=1 -DUSE_IPv6=1 -I. -I. -I/usr/kerberos/include -DLIBDIR='"/usr/local/lib/stunnel"' -DCONFDIR='"/usr/local/etc/stunnel"' -DPIDFILE='"/var/run/stunnel/run/stunnel/stunnel.pid"' -g -O2 -Wall -Wshadow -Wcast-align -Wpointer-arith -I/usr/local/ssl/include -MT file.o -MD -MP -MF ".deps/file.Tpo" -c -o file.o file.c; \ then mv -f ".deps/file.Tpo" ".deps/file.Po"; else rm -f ".deps/file.Tpo"; exit 1; fi *In file included from /usr/include/sys/signal.h:34,* from /usr/include/signal.h:26, from common.h:250, from file.c:38: /usr/include/sys/siginfo.h:259: error: parse error before "ctid_t" /usr/include/sys/siginfo.h:292: error: parse error before '}' token /usr/include/sys/siginfo.h:294: error: parse error before '}' token /usr/include/sys/siginfo.h:390: error: parse error before "ctid_t" /usr/include/sys/siginfo.h:392: error: conflicting types for `__proc' /usr/include/sys/siginfo.h:261: error: previous declaration of `__proc' /usr/include/sys/siginfo.h:398: error: conflicting types for `__fault' /usr/include/sys/siginfo.h:267: error: previous declaration of `__fault' /usr/include/sys/siginfo.h:404: error: conflicting types for `__file' /usr/include/sys/siginfo.h:273: error: previous declaration of `__file' /usr/include/sys/siginfo.h:420: error: conflicting types for `__prof' /usr/include/sys/siginfo.h:287: error: previous declaration of `__prof' /usr/include/sys/siginfo.h:424: error: conflicting types for `__rctl' /usr/include/sys/siginfo.h:291: error: previous declaration of `__rctl' /usr/include/sys/siginfo.h:426: error: parse error before '}' token /usr/include/sys/siginfo.h:428: error: parse error before '}' token /usr/include/sys/siginfo.h:432: error: parse error before "k_siginfo_t" /usr/include/sys/siginfo.h:437: error: parse error before '}' token In file included from /usr/include/signal.h:26, from common.h:250, from file.c:38: /usr/include/sys/signal.h:85: error: parse error before "siginfo_t" In file included from common.h:250, from file.c:38: /usr/include/signal.h:111: error: parse error before "siginfo_t" /usr/include/signal.h:113: error: parse error before "siginfo_t" In file included from common.h:251, from file.c:38: /usr/include/sys/wait.h:86: error: parse error before "siginfo_t" make[1]: *** [file.o] Error 1 make[1]: Leaving directory `/root/syslogNG/stunnel-4.26/src' make: *** [all-recursive] Error 1 Is that normal that i've 2 signal.h files ?

I do not think that this can work. SFTP is not just encrypted FTP traffic, but an entirely different protocol.

0x09 bytes in stunnel-4.26/src/Makefile.am
by Andrew Schulman 14 Jan '09

14 Jan '09

For some strange reason, there are five hex 09 bytes in stunnel-4.26/src/Makefile.am. This broke my Cygwin build: I remove the Windows-only stuff from this file for Cygwin, and diff captured the 0x09 characters that got removed, but then when I later tried to apply the patch, patch choked on them. It seems that each of these bytes should really be 0x0A. Strange. Andrew.

One problem I have found in doing this is that if socketpair(2) is used to create the file descriptor that will be connected to stunnel's stdio, then stunnel's libwrap checking is activated because it detects it to be a socket. Using socketpair is a nice way to turn a TCP client into one that connects via a two-way pipe with stunnel (because the client app doesn't have to special case the two file descriptors for stunnel's stdin and stdout when reading and writing.) Since a user (i.e. not a sysadmin) has no control over the libwrap settings in /etc, stunnel's libwrap check will always fail when used this way. In my opinion, stunnel should allow disabling of libwrap (and syslog too) via the config file (i.e. not just compile time options). This makes the "one connection" client usage you describe work better. Karl

Re: [stunnel-users] How do I do a one-time client connection?
by D. Richard Hipp 13 Jan '09

Perhaps I spoke too soon about having solved my own problem. Suppose I have a configuration file (test.conf) like this: client=yes connect=www.fossil-scm.org:443 Then if I run: stunnel test.conf And I type "GET / HTTP/1.0" on standard input, the webpage comes back on standard output. So far so good. But if I do: stunnel test.conf <test.in >test.out Where file test.in contains the "GET / HTTP/1.0" test, I get nothing back! I also tried this: cat test.in | stunnel test.conf And various combinations of this: openssl s_client -connect www.fossil-scm.org:443 <test.in In every case, when I type the GET line on standard input it works. When I redirect from a file it does not. Any hints on the cause of the very unexpected and very mysterious behavior? D. Richard Hipp drh(a)hwaci.com

How do I do a one-time client connection?
by D. Richard Hipp 13 Jan '09

13 Jan '09

I'd like to invoke stunnel to handle a single SSL client-side connection (talking to an SSL server) with the assurance that the stunnel quit will automatically quit after that one connection closes. I did not see any options to support this. Did I overlook something, or is stunnel just not able to do this? D. Richard Hipp drh(a)hwaci.com

public domain [PATCH] to stunnel 4.27b1 for Windows CE / Windows Mobile compilation and unicode bug fixes
by Pierre DELAAGE 10 Jan '09

10 Jan '09

Dear Sir, Please find enclosed a patch in "diff -cr orig work" format, applying to stunnel4.27b1 as found here ftp://stunnel.mirt.net/stunnel/. This patch maily addresses compilation and unicode issues for Windows CE targets. I use MS EVC 4sp2 compiler with WCE 420 SDK, on a vista host platform. Once debugged the code works fine on WM5 and WM6 HTC smartphones. It needs a windows CE openssl lib (I logged a patch to openssl snap 20090102 because it has some compilation issues on windows CE platform). * For the sake of completeness openssl 098i and 098j (latest) must be ALSO patched to compile for wince, with this patch I submitted to openssl team : http://marc.info/?l=openssl-dev&m=123099015013538&w=2 The present stunnel patch addresses the following issues : 1/ COMPILATION FAILURE : on common.h "EINVAL redefinition" : in fact the compile options WX (see evc.mak) does not tolerate any warning : to avoid a warning on EINVAL redef, we must protect this undef by ifdef. Note that there is still a problem : if the symbol is NOT defined at all, it will NEVER be defined by that revised code : this is because the compiler always generate an error if it sees something like : #ifdef EINVAL #undef EINVAL #define EINVAL WSAEINVAL #else #define EINVAL WSAEINVAL #endif because it seems to not like two defines even separated by a else. Just putting the #define outside of a block dealing with undef, does not solve the compilation issue. 2/ COMPILATION FAILURE : related to wcecompat/setjmp.h SOLUTION : in evc.mak, needed /D ARM to compile with wcecompat/setjmp.h. This symbol is not documented in MSDN but clearly present is header files. Moreover It is consistent with other processor symbols described in the sdk. 3/ COMPILATION FAILURE : related to gui.c pb with undeclared hmainmenu identifier, because "endif use_win32" misplaced. 3/ RC COMPILATION FAILURE : related to resources.rc CAUSE : "VERSION" unknown SOLUTION : /dversion in rflags in evc.mak 4/ LINK ERROR : fatal error LNK1181: cannot open input file 'libeay32.lib' cause : bad path name in evc.mak for openssl lib. since openssl >> 098a (eg 098h) "out32dll" folder is named "out32dll_targetCPU". 5/ LINK ERROR on gui.obj : error LNK2001: unresolved external symbol _beginthread _$(TARGETCPU) Cause : in sthreads.c, misplaced "#endif os2" Note : corrected various erroneous comments on #if endif in sthreads.c ************* OPERATIONAL ERRORS (at run-time) using stunnel to enable certificate based authentication for POPS/SMPTPS between a smartphone and a linux server, I faced this problems : When first trying to authenticate a dlgbox is displayed on the smartphone to input the password of the private key protecting the client certificate: 6/ RUN-TIME ERROR : "squares" displayed instead of chars in "password input dialog box" titlebar Well, this is only a cosmetic issue, but this is still an issue. Cause : this is a typical unicode issue in gui.c pass_proc/wm_initdialog : the sendmessage to display the title uses a concatenation of two strings : a constant extracted from the resource file, and converted to wchar by TEXT macro in unicode context, and a key file name given by ui_data->section->key. The problem is that the file name is always of type 8bit char, leading to concatenation "scrambling" when concatenated with a unicode string. SOLUTION : it seems not possible to change the type of ui_data->section->key to tchar/wchar because it is used in various ansi code. So the simplest way to correct this pb is just to make a local conversion from ansi to tchar in gui.c/pass_proc/initdialog 7/ RUN-TIME ERROR : It is impossible to validate a password on a private key protecting a certificate: The password is ALWAYS rejected (after many tests with 3 retries). Cause : the password is input as unicode (because the message EM_GETLINE on the control IDE_PASSEDIT is unicode ready) but stored and managed as an ansi string so the password can never be validated. NOTE : contrary to the documentation of windows CE sdk, the EM_GETLINE msg IS REALLY unicode ready. Indeed this is also the case in classic win32 sdk for PC platform (described in the msdn library). SOLUTION : the input password must be converted to ansi before being validated vs openssl 2009.01.05 13:00:01 LOG3[4849170:5712826]: Wrong pass phrase: retrying 2009.01.05 13:00:05 LOG3[4849170:5712826]: error stack: 140B3009 : error:140B3009:SSL routines:SSL_CTX_use_RSAPrivateKey_file:PEM lib 2009.01.05 13:00:05 LOG3[4849170:5712826]: error stack: 906A065 : error:0906A065:PEM routines:PEM_do_header:bad decrypt 2009.01.05 13:00:05 LOG3[4849170:5712826]: SSL_CTX_use_RSAPrivateKey_file: 6065064: error:06065064:digital envelope routines:EVP_DecryptFinal_ex:bad decrypt 2009.01.05 13:00:05 LOG3[4849170:5712826]: Server is down I hope you will find this patch useful. Thank you for your excellent work, Yours sincerely and happy new year, Pierre Delaage Note : I use stunnel to establish a simple "vpn" between smartphones and a corporate linux server mainly for HTTPS/POPS/SMTPS support. Stunnel is very relevant in that matter, over solutions based on SSH (although we use also ssh), from a communication cost point of view : ssh establishes permanent socket between client and server, so that the communication is charged by the mobile network provider : and these charges are very expensive. On the contrary stunnel only establishes ssl sockets on demand so that financial charges are limited to strict necessary. Please note that stunnel brings "client based certificate authentication" to POP/SMTP mobile mail user agents which only supports SSL with server authentication, but NO client authentication, such as mobile outlook.Here again stunnel is very relevant. Note 2 : the unicode bug fixes should benefit also to the win32 stunnel version for PC. Note 3 : this mail has also been sent to webmaster(a)stunnel.org, but with no response at all.

Squid documentation will tell you what is the need for the home-made authentification program. I think it's easier with DansGuardian proxy : - In stunnel config file : select pertinent fields of the certiificate : only Issuer_CN -> identFields=32 - in /etc/dansguardian/dansguardian.conf, create 2 groups : filtergroups = 2 filtergroupslist = '/etc/dansguardian/lists/filtergroupslist' - create filter groups in /etc/dansguardian/lists/filtergroupslist. (All not matching users will go in group 1) : put a line like "your issuer CN equals 2" - in /etc/dansguardian/dansguardianf1.conf, put "groupmode=0" , ie banned - in /etc/dansguardian/dansguardianf2.conf, put "groupmode=2" , ie non filtered Note that the authentification of the users is done by stunnel. Stunnel forwards the identification to the proxy which does not need to authenticate since it was done by stunnel. If the ident provided by my patch is not convenient, you can modify it to match your needs. Hope this helps -- Christophe Nanteuil
