      Xrootd Protocol Update 20m
      Speaker: Wei Yang (SLAC National Accelerator Laboratory (US))
      • Xrootd release candidate 4.9.1rc2 tagged - bug fix, nothing to do with Xrootd TPC (but has something needed by HTTP TPC)
      • Working with several DPM sites to setup Xrootd TPC. 
      • Working with BNL on their setup - it is a special case where dCache xrootd is behind a firewall
      • Working on dCache xrootd X509 authentication issues
        • We suspect that randomized IV (initial vector) in Xrootd GSI authentication may have trigger some inconsistent paddings issues (of "zeros") between OpenSSL and Bouncy Castle (Java), and cause communication failure between native xrootd and dCache xrootd in ~1/200 cases.
          • Looks like we are close to fix this issue (Thanks Paul, Albert and Gerri!)
      • Working with RAL on Xrootd TPC for ECHO:
        • Single slash issue (ECHO's xrootd URL use a single heading slash in "path" - object id)
          • Plan is to not modify the existing CEPH plugin for Xrootd, but
          • Add a (Xrootd OUC) Name2Name to remove the extra slash 
        • Trying to understand TPC issues with ALICE at RAL/ECHO, which uses their own authentication tokens.
