Very rough patch
This is a patch I sent to Wayne Davison on 22nd July 2014. It is not "production ready" - just a starting point to see how things fit.
It adds in libdetectcoll from Marc Stevens - it's compatible with the normal MD5_Update() interface, but adds a return value to tell when a collision attempt is detected. In these cases a full transfer should be done rather than partial.
It also pulls in blake2b as a hash function with a new protocol number (old clients will still used md5 or md4, depending on how old).
I don't even know if this works, it was really just a (failed) way to start a discussion. Hopefully somebody can pick this up and beat it into shape. Cleaning up libdetectcoll itself to use rsync's print functions etc would be a minimum requirement, I'd guess.
This message is a reminder that Fedora 20 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 20. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora 'version'
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.
Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 20 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
Thank you for reporting this bug and we are sorry it could not be fixed.
