Hi everyone. My name is Elie TOURNIER, I am a last year undergraduate student enrolled in a 5 years Medical ICT course at Télécom Physiques Strasbourg, France. I came to know about the Ceph project and would like to contribute to "RBD diff checksums subject" as a part of GSoC 2016. I am fluent in C/C++ and know a bit about cryptography. I have many ideas but I have some questions too. So questions: 1- Is this feature must be integrated to the Ceph code or must be a standalone? 2- What is the maximum time allowed for the checksum? My ideas: 1- Use fast hash algorithm like xxHash [1] or Highwayhash [2] in order to reduce computation time. 2- Use the size of the file as a seed.

Regards, Elie TOURNIER PS: If you have any questions, remarks about me or my ideas for the project, don't hesitate to contact me. -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
