crypto module not working

This makes ejabberd completely unusable, as reported in bug #68801.

I think this could be the same as a bug I submitted, bug #68933. Can anyone confirm?

This seems to work fine on the amd64 version of edgy

This particular problem doesn't seem to manifest upstream in Debian. I had a friend try this on Debian Unstable:

 1> crypto:start().
 ** exited: {undef,[{crypto,start,[]},
                    {erl_eval,do_apply,5},
                    {shell,exprs,6},
                    {shell,eval_loop,3}]} **
 =ERROR REPORT==== 15-Dec-2006::23:16:27 ===
 Error in process <0.30.0> with exit value:
{undef,[{crypto,start,[]},{erl_eval,do_apply,5},{shell,exprs,6},{shell,eval_loop,3}]}
 2>

For reference, on my edgy system:

[nick@frotz(~)] dpkg -S crypto_drv.so
erlang-base: /usr/lib/erlang/lib/crypto-1.5/priv/lib/crypto_drv.so

And on my friend's Debian Unstable system:

erlang-base-hipe: /usr/lib/erlang/lib/crypto-1.5/priv/lib/crypto_drv.so

So it is in the same location as Debian's. Why then doesn't it load on Ubuntu?

Actually this proves only that crypto is broken at debian unstable too. Though in some different way.

If it were working you'd see this:

zeank@sz2:~$ erl
Erlang (BEAM) emulator version 5.4.9 [source] [threads:0]

Eshell V5.4.9 (abort with ^G)
1> crypto:start().
ok
2>

If you get

{undef,[{crypto,start,[]},{erl_eval,do_apply,5},{shell,exprs,6},{shell,eval_loop,3}]}

instead, this means that a matching call 'start' within module 'crypto' could not be found.

That said, the friend *was* able to fire up ejabberd and connect with a jabber client. Admittedly it was on powerpc, and I've seen some folks say that things work fine on amd64. This may be an i386-only bug, and I believe my friend is testing on his x86 Unstable box now.

zeank: turns out he didn't have erlang-nox installed. once he grabbed that, everything worked.

I got it working by recompiling the erlang packages using gcc-4.0 instead of gcc-4.1 as hinted deep in this thread:

http://www.erlang.org/pipermail/erlang-questions/2006-November/023840.html

$ erl
Erlang (BEAM) emulator version 5.5.1 [source] [async-threads:0] [kernel-poll:false]

Eshell V5.5.1 (abort with ^G)
1> crypto:start().
ok
2> q().
ok

In that case, it's probably an issue with optimised optimisations in GCC
4.1... I'll look into it tonight, and hopefully get the package fixed as
well.

Did you see any results? Will there be a new package in feisty any time soon?

I recompiled it 3 times over the past 48 hours, with different
optimisation settings and compilers. Building Erlang with GCC 4.1 always
generates this issue, even with optimisations turned off. GCC 4.0 works
fine. Unless we can work out what in particular is causing it to fail
(and fix it), I'll upload it soon to build using GCC 4.0 instead.

Hi,

have you tried to add "-fno-stack-protector" to the CFLAGS, as suggested in this thread in the Erlang forum : http://forum.trapexit.org/viewtopic.php?t=6630&highlight=cryptodrv

Best Regards,
Patrick.

I have tried it now and it works. You need to download erlang-base source, add "-fno-stack-protector" into CFLAGS in rules file in debian directory, run dpkg-buildpackage and install erlang-base and erlang-nox which you've build earlier. And ejabberd works like a charm :)

This is a bug in erlang and not in ejabberd.

I just created a .debdiff for Feisty, which should fix the issue. Currently, I am recompiling erlang, which will take some time (it is huge). I will leave a note if it really fixes the issue.

Works fine now:

Erlang (BEAM) emulator version 5.5.2 [source] [async-threads:0] [kernel-poll:false]

Eshell V5.5.2 (abort with ^G)
1> crypto:start().
ok
2>

Could anyone please sponsor the upload to Feisty?

I applied the patch, built the package and tested the functionality. Everything is fine. Uploading.

Thank you for your work on this bug Martin.

Still the same problem here : crypto_drv: not found

Note that this has only been fixed in the current development release
(Feisty) of Ubuntu.

Hi,
 Me too faced the same problem but found the solution.
 When i tried to install first time, after ./configure CFLAGS="-fno-stack-protector"
 the following message has been displayed.
 **************************************
 crypto : No usable OpenSSL found
 jinterface : No Java compiler found
 odbc : ODBC library - link check failed
 orber : No C++ compiler found
 ssh : No usable OpenSSL found
 ssl : No usable OpenSSL found
 ***************************************
 i found openssl development environment is missing which is why "crypto" application is failed to start.

 then i installed it from
 ftp://ftp.openssl.org/snapshot/openssl-0.9.7-stable-SNAP-20080428.tar.gz

 now i reinstalled erlang as follows
 1. ./configure CFLAGS="-fno-stack-protector"
 2. make
 3. make install

 Happy day... crypto is working

 my gcc version is 4.2.3gcc (GCC) 4.2.3 (Debian 4.2.3-3)
 erlang src: otp_src_R12B-2
 emulator version : 5.6.2

Thanks & regards
