Timeline for the next UMD updates

New UMD release process timeline

Updates from the product teams

This section is directly contributed by the product teams. Please, add under your section the scheduled releases with a short comment about the updates introduced and where they are going to be released (EMI repositories, EPEL, private repositories ecc), linking external pages with these information is ok, but please add at least the expected date of the next release. It is important to discuss, within the URT, changes that may affect directly or indirectly other products. The text will be copied into the agenda of the next URT meeting, PT will just need to check that all the information are up to date. Please, feel free to alter the template if it doesn't feet with your needs.

(expected in the course of 2015 that we will publish packages for UMD via AppDB at https://appdb.egi.eu/store/software/unicore

For now, packages for UNICORE 7.2.0 can be downloaded from

Debian: http://unicore-dev.zam.kfa-juelich.de/release-candidates/core/7.2.0-packages/deb

RPM: http://unicore-dev.zam.kfa-juelich.de/release-candidates/core/7.2.0-packages/rpm

RPM packages were tested on Centos 6, so SL6 will be fine. SL5 is NOT supported any more.

Changes are listed with respect to the last UNICORE version available in UMD which is 6.6.0

The updated globus-gssapi-gsi version 11.16 in EPEL testing changed the default name compatibility mode from "HYBRID" to "STRICT_RFC2818". This caused some issues when tested on some deployed systems. See the GGUS ticket for details:


To remedy this upstream issued an updated version 11.18 that changed the default back to HYBRID. However, upstream considers this to be a temporary measure, and would like to change the default to "STRICT_RFC2818" eventually.

The EPEL update request has been modified to now use the 11.18 version.

The issues in the GGUS ticket were mainly due to configuration mistakes such as a reverse DNS lookup pointing to the wrong name or host certificates that didn't have the hostname listed in alt subject names and are basically understood.

You can test the impact of different name compatibility mode settings on your software by changing the name resolution mode in the configuration file /etc/grid-security/gsi.conf (introduced in version 11.15) or by using the GLOBUS_GSSAPI_NAME_COMPATIBILITY environment variable. The environment variable has precedence over the config file setting.

The "HYBRID" setting in addition to the RFC 2818 way of doing name comparison also accepts the old GT2 way of doing this, which includes accepting matching to the name from the reverse DNS lookup. This by some is considered a security problem, and changing the default to "STRICT_RFC2818" will avoid this.

More details about the different name compatibility modes from /etc/grid-security/gsi.conf is copied below:

# GSSAPI Name compatiblity mode when trying to determine
# if a host certificate is legitimate. GSI predates RFC2818,
# so there are some old, less-secure, practices by default.
# The different modes are:
#     Strictly backward-compatible with GT 2.0 name matching. 
#     X.509 subjectAltName values are ignored. Names with
#     hyphens are treated as wildcarded such that 
#     host-ANYTHING.example.com will match a certificate named
#     host.example.com. The name matching will rely on canonical
#     host (as resolved via getnameinfo) name associated with
#     a connection's IP addresses.
#     Support RFC 2818 server identity processing. Hyphen 
#     characters are treated as normal part of a host name. 
#     dnsName and ipAddress subjectAltName extensions are matched
#     against the host and port passed to GSSAPI. If subjectAltName 
#     is present, X.509 SubjectName is ignored. 
#     Support a hybrid of the two previous name matching algorithms,
#     liberally matching both hyphen wildcards, canonical names
#     associated with IP addresses, and subjectAltName extensions.
#     This has been the default since GT 4.2

This update is currently being pushed to EPEL stable, and the GGUS ticket was closed with the following resolution: "Problem is well understood and many options now exist for the short term and plans for the medium term."

The upstream developers say: "We'll probably be including the change to strict by default as part of the 6.1 release later this year."

So consider this a heads up for reintroducing the change in default.

Another set of updates was released by upstream last week. Changes are minor but includes an update to myproxy to fix a glitch in its RFC2818 support.

History of Globus updates in EPEL (since GT 6.0)


Next Release is planned for UMD update in May.


xrootd 4.2.1 available in EPEL.

After two weeks in EPEL testing the updates have been pushed to EPEL stable 2015-06-20. No feedback was recieved during the period the updates spent in testing. Hopefully this means that no problems were found during testing. (It can also mean noone bothered to do any testing, but you are not that careless - right?)
