A patch adding SNI support to M2Crypto.
Description of problem:
M2Crypto doesn't support SNI (Server Name Indication).
This feature is necessary for selecting the right SSL-protected web site hosted using name-based virtual hosting on a shared IP address.
All modern browsers support this feature.
However, Python programs which use M2Crypto for programmatic access to SSL-protected web services can't use SNI because it's not implemented in M2Crypto.
The manifestation of lack of SNI support is error message about wrong site certificate.
Version-Release number of selected component (if applicable):
Connect using Connection class from M2Crypto.SSL.Connection module to any SSL-protected site hosted using name-based virtual hosting, which requires SNI support to distinguish between virtual hosts.
One of the programs using M2Crypto is osc
which is packaged for Fedora.
You can use it to test lack of support for SNI in M2Crypto, but if solution proposed below is implemented, osc needs a separate patch to use SNI.
Steps to Reproduce:
osc ls https://jr.infoserver.lv/obsapi
Error about wrong SSL certificate.
No error about wrong SSL certificate.
This is a known issue described here:
This bug report has a patch attached which enables SNI support in M2Crypto.
Unfortunately, M2Crypto development has stopped in January 2011 (this is when the last commit to http://svn.osafoundation.org/m2crypto/trunk Subversion repository was made).
Hence, we're stuck with adding patches to packages.
I've attached the patch adding SNI support to M2Crypto.
You can find SRPM of m2crypto with SNI support here:
Sounds reasonable, thanks for the patch.
(I should investigate using %rename like many other wrappers do.)
