Contract SFS-DEV-002

= Summary = This project involves two improvements to Lustre's security features:
 * A mapping feature to allow clusters with different UID/GID sets to use a single common Lustre filesystem
 * A shared-key authentication and encryption scheme based on Lustre's GSS mechanism, as a simpler alternative to Kerberos.

2013-09-10
Attending: nathan, andy, josh, simms, andreas

Meeting Minutes:
 * No meeting next week due to LAD
 * Andy: [LU-3490] landed
 * Build works on test cluster
 * AI: But some build environments still lack libkeyutils, so Andy will attach another patch to LU3490 to change autoconf to detect missing libkeyutils and disable gss/kerb build
 * AI: Andy has noticed that the gssd userspace app doesn't appear to be included in the Lustre RPMs, and will check on it
 * [LU-3288] is waiting for Andy to add the GSS NULL mechanism so that GSS can be tested independently of KRB.


 * Josh: will land the changes from the [LU-3527] reviews hopefully by the end of the week, included a rebase to Master.
 * Maintenance: Andy asked who would keep the code updated; the answer is the community and/or maintenance contract, but helpful things:
 * Make sure unit tests provide good automated coverage
 * Make sure code is well documented


 * Closed actions:
 * AI: missing keyring [LU-3681] resolved for test nodes

Actions:
 * AI: Andy to add check for libkeyutils to LU-3490

2013-07-09
Attending: Josh, Andy, Steve, Andreas, Ken, Nathan

Meeting Minutes:
 * LU-3527 patches in gerritt

2013-06-25
Attending: steve, josh, andy, nathan, andreas, alex, ken, ned, john

Meeting Minutes:
 * There remain Gerritt and Git problems; these are slowly being worked.
 * UID mapping phase 1 (management interface, node map structures) has been uploaded to Jira (IU-3)
 * Reviewer volunteers: Andreas (or Fan Yong), Ken
 * Needs to be moved to a LU- ticket for visibility.
 * phase 3 (UID mapping) up next, working on unit tests
 * phase 2 (MGS pushing/syncing node map) will be worked on after phase 3.
 * Andy has provided a patch to enable gss by default - LU-3490
 * LU-3288 is a probably a pre-req to landing this
 * kerberos tests do pass if proper Kerberos authenticated setup
 * without gss-null landing, currently no gss tests will pass
 * we need to change the patch such that gss is only enabled if the libraries are found

Actions:
 * AI: Andy to add checks for gss libs before enable-gss (LU-3490)
 * AI: Ken to provide simply Kerberos server setup recommendations and potentially unit tests

 * Justin is collecting a list of required GSS/Kerberos libraries for builders
 * Discussed how we can begin adding this code to autotest
 * configure/build needs to autodetect GSS/Kerberos libraries for Gerrit builds

2013-05-28
Attending: josh, andy, nathan, andreas, alex

Meeting Minutes:
 * [LU-3288] discussion - who will do this work?
 * Is there a kerberos-interested maintainer? Kerb users: PSC, Fermi, UofFL, NRL
 * Note the separation of the build options also implies a separation of #ifdef macros inside of Lustre.
 * Noted that there are 3 "null" mechanisms: gss-null != sptlrpc-null (doesn't use gss) != krb5 "plain"
 * Questions on existing sptlrpc:
 * How is non-krb security level required - mount option
 * Can a single rpc be not encrypted after connection negotiation?
 * Existing Lustre security tests eventually need to be separated:
 * sanity-gss should become sanity-krb5
 * sanity-krb5 should add tests for krb5 "plain" mechanism
 * sanity-gss should eventually use the gss-null mechanism that IU is developing
 * sanity-sptlrpc should be written to test sptlrpc "null" in the absence of GSS.
 * Closed actions
 * Andreas to provide instructions for autotest
 * tune testing for a particular patch. This allows specifying a patch is being submitted for testing (i.e. fortestonly), a list of test scripts to run (e.g. testlist=sanity-sec,sanity-gss), and setting environment variables (e.g. envdefinitions=GSS_PIPEFS=true), etc.
 * Some (sparse) documentation on how to run the test scripts:
 * Some older (and partly out of date) information on the specific testscripts are available at:

2013-01-29
Attending: Andreas, Andy, Alex, Josh, Nathan, Ned

Meeting Minutes:
 * Key scope: sets of keys are defined per cluster (not per-client)
 * These keys are used to generate session keys for Auth and Encrypt
 * Root squash - various ideas
 * EAs on directories describe which clusters are allowed
 * Squash per-cluster roots to distinct users, use ACLs to provide per-cluster root-like permissions
 * Use bind-mounting to limit the visibility of the fs to a subtree
 * suggestion to add root fid/path to cluster definition for future use
 * Current plan: root is not treated specially - per-cluster roots may be mapped to the actual fs root user, or not.
 * Object (OSS) security against untrusted client - out of scope
 * MGS primacy
 * "MGS up before before other servers" may be a requirement for the mapping or shared key features
 * but this requirement must be relaxed if the uid/shared key feature has not been enabled

Actions:


 * Nathan to send HLD example template (done)
 * Nathan to propose OpenSFS contract doc templates
 * Andy/Josh update HLD with detail

Milestones Under Review:
 * UID HLD
 * Shared Keys HLD

Next Meeting:
 * I will be travelling for the next two meetings (Feb 5, 12). Can someone else host the meeting?
 * 12:00pm PST Feb 5 2013
 * Intercall (866) 203-7023
 * Conference code: 5093670258

2013-01-22
Attending: Nathan, Josh, Andrew, Steve

Meeting Minutes:
 * Comments on Shared Keys HLD
 * 1) independence of auth and encrypt keys
 * 2) encrypt-then-MAC
 * 3) HLD should address multiple simultaneuous keys
 * 4) interaction between shared keys and mappings
 * 5) * original assumption was key-per-client; key-per-cluster seems to make more sense for a few reasons (large-cluster manageability, shared-root clients). A hash of the keys could be added to a cluster definition.  A "null" cluster could be defined for a single-cluster environment.
 * Ended meeting early; we need more meeting attendees to discuss these issues.

Actions:
 * Review Security HLD to provide timely feedback.

Milestones Under Review:
 * UID HLD
 * Shared Keys HLD

Next Meeting:
 * 12:00pm PST Jan 29 2013
 * Intercall (866) 203-7023

2013-01-15
Attending: Nathan, Ned, Josh, Andrew, Steve, Alex, Andreas, John

Meeting Minutes:
 * UID/GID HLD Review
 * Comments by Nathan, Andreas, Ned returned via Word doc
 * Define/update cluster definition via complete file vs. incrementally
 * Josh: file-based cluster def changes requires walking export tree
 * Done rarely, probably ok
 * There may be security implications at the transition when redefining cluster defs
 * When a NID is removed from a def it should use the default mapping


 * Define/update UID/GID mappings via complete file vs. incrementally
 * incremental uid/gid mapping in order to prevent fs access blocking during replacement.
 * Andreas suggested atomically swap in new mapping once received/set up.


 * Behaviour during setup and recovery
 * Don't use default mapping while waiting for definitions; FS should block access to all files until mappings and cluster defs have been set up.
 * Need a clear signal when an update is finished/complete.
 * Servers currently cache the MGS Lustre config locally
 * May be undesirable for OSD
 * Perhaps this behaviour should be changed: stop caching, require MGS for server startup.


 * Shared Key HLD distributed
 * Comments should be returned quickly for HLD revision next week.

Actions:
 * Review Shared Key HLD to provide timely feedback.

Milestones Under Review:
 * UID HLD
 * Shared Keys HLD

2012-12-11
Attending: Nathan, Andreas, Josh, Simms, Cory, Alex, Andrew Meeting Minutes:
 * Josh and Andrew updated the arch docs with improved use cases, test plan, and acceptance criteria
 * Several PAC members commented on the updates
 * Alex noted we neglected to address previous discussions on allowing multiple simultaneous keys:
 * should we allow key updates on a live system, or connect-time only?
 * is there any upper limit on total keys?
 * should keys be restricted to particular nid range?

Actions:
 * PAC members review docs for final approval by next week.
 * The above multiple-key use case should be added to the arch doc.
 * In the meantime HLD design can begin
