Re: [ptxdist] [PATCH] libcoap: add new package

[Alexander Aring]

Hi Michael,

ping.

I see you applied other patch "libzmq: add new package" already. Is
there something wrong with this patch or simple needs a little more time
to review? :-)

Re: [ptxdist] [PATCH 3/3] Rules to build ghostscript for the host.

[Juergen Beisert]

Hi David,

welcome to the printing hell :)

I also tried with CUPS and Ghostscript. Its far from perfect, but it seems to 
work. The CUPS project is not interested in cross compiling (there was a 
statement at one of their mailing lists longer time ago and their buildsystem 
is really broken regarding this) and the Ghostscript buildsystem is an ugly 
mixture of autotools based configure and hand made Makefiles. A real mess. I'm 
using Ghostscript 8.70. Should I send my variant as well?

Regards,
Juergen

Hi David,

I looked last night a little bit deeper into cups and ghostscript
buildsystems and it seems that cross-compiling these tools is a mess.

I will see what I can do for it. Don't believe that I can do miracles.
Of course there must a way to cross compiling it. :-)

mhh, this statement must ending with:

"With best regards Apple Inc." ;-)

Otherwise you could do a fancy airprint with non apple embedded devices.

I need some clarification mostly. You're replacing the whole build-system.
That's not something I want to maintain inside ptxdist. I can only accept
that if this will be upstream the next time we update the package in
ptxdist. So what's the upstream status of these patches?

Re: [ptxdist] Cross-compiling gstoraster

[David Thomas]

Hi Alex,

Thank you so much for looking into this, whether or not you get anywhere with 
it.

I'm looking at stepping outside the Ghostscript make system and producing a 
custom command to run in the ptxdist build rules to make my version, perhaps 
after the standard make system has built everything else (which now works, at 
least as far as compiling goes). I don't consider it the correct approach but I 
can't see how else to proceed at this time.

Thanks,
David

Hi Juergen,

If you got Ghostscript 8.70 to work with CUPS, I would be deeply interested in

Maintainer don't want to use automake in his buildsystem, I think it
will never go into mainline of libcoap. There is also no mailinglist for
this project, I mailed with the maintainer private.

General problem:

The library buildsystem was made for static linking to a non dynamic
loading operation system.


I can try an alternative instead of reimplemnt the whole buildsystem.

Steps are:

1. Patch libcoap package to add a libcoap.pc file with static paths and
   add CFLAGS with -D WITH_POSIX.

2. Compile shared libcoap library with make and -D WITH_POSIX
   (There exists a way mainline to compile a shared library)

3. on make install, install it to static path usr/lib/ and
   usr/lib/pkgconfig usr/include...

3.1. There is something special on header copy to usr/include:
 copy a dummy header for config.h (I hope that should work).
 Normally the config.h is created by autoconf and they included it
 in every header but no header use config.h information in the header
 files (I suppose). So we don't need patch 4/6 (libcoap: remove
 include of config.h).

4. copy library, headers into LIBCOAP_PKGDIR.

Something in that way...

I think all option will be end in some hack. I can try to do the
alternative and then we looks if it's better or not, if you are
interested in.

Re: [ptxdist] Cross-compiling gstoraster

[David Thomas]

Hello,

I would like to express my thanks to all of you, and especially Juergen. With 
minor modifications, his patches for Ghostscript worked fine on my end, and I 
now have CUPS and Ghostscript working fine on my target!

I have provided Juergen with a copy of my rules and patches. It would be really 
nice to see CUPS and GS make it into the main PTXdist and I hope what I have 
done helps.

Many thanks,
David

[ptxdist] Busybox password hashing algorithm

[Matthias Klein]

Hello,

our ptxdist 2014.01.0 based product got an external security audit.
They complained that our passwords in the shadow file are hashed with 
the outdated crypt(3) algorithm.

Her advice is to use bcrypt, PBKDF2 or scrpy.

We are using busybox for passwd etc.

Is this a busybox limitation? Or can we change the hashing algorithm in 
busybox?

Or do we need to replace busybox' passwd etc. with something better?


Best regards,
Matthias

Have a look at the  BUSYBOX_USE_BB_CRYPT and BUSYBOX_USE_BB_CRYPT_SHA
option.

Re: [ptxdist] Busybox password hashing algorithm

[Matthias Klein]

Hello Marc,

thanks a lot for the tip !

With that option I can login with a SHA hashed password (starts with 
$6$).
But if I change the password with passwd (from busybox) I get again a 
"weak" hashed password.


I looked for a similar config option for passwd, but can't find one.
Is there a way to create SHA hashs with passwd from busybox ?


Best regards,
Matthias

[ptxdist] Hostap-ol.R5.SP7.01

[Ivor Kruger]

Hi, I need to get the latest version of hostap included into my ptxdist
build for the phycore. I copied the i.MX files and got the older version
working (sort of). I don¹t understand all the intricacies of ptxdist and
read the guru doc on how to add packages but still struggle.

Is there a later version of hostap included in some other ptxdist
distribution that I can hack toward the latest version?

Or maybe some pointers on how to get the current version going.

For the record, here is a link to the hostap files:
https://github.com/TI-OpenLink/hostap/archive/ol_R5.SP7.01.tar.gz

I would appreciate any help/pointers.
Regards
Ivor

Re: [ptxdist] Busybox password hashing algorithm

Hello Marc,

I have found the solution: the default algorithm for passwd can be set 
with the config option CONFIG_FEATURE_DEFAULT_PASSWD_ALGO.


I will send a patch tomorrow.
