Hi Casey, That warning message tells users to upgrade to a new version of libcurl. Telling users to upgrade to a newer version of a base system package like that sets the user on a trajectory to have to maintain their own curl packages forever, decreasing the security of their overall system in the long run. For example ceph.com itself shipped a newer el6 curl package for a while in "ceph-extras", until it fell of everyone's radar, no one updated it, and it had many outstanding CVEs until we finally dropped el6 support altogether. Would you please remove this last sentence from the RGW log message? - Ken On Fri, Sep 16, 2016 at 12:02 PM, Casey Bodley <cbodley@xxxxxxxxxx> wrote: > In the meantime, we've made changes to radosgw so that it can detect and > work around this libcurl bug.
