https://jira.whamcloud.com This file is an XML representation of an issue en-us 9.4.14 940014 05-12-2023 https://jira.whamcloud.com/browse/LU-9680 Lustre <p>Lustre currently has a complex assortment of ioctls for both the file system component and the LNet layer. Many of the those ioctls are no longer used or can be replaced with accessing files in the sysfs or debugfs file systems. With the initial review of lustre in the upstream kernel two topics on how ioctls are managed to brought to our attention. One is the dislike of the ioctl redirection that is done in lustre. The seconds is the request that we use the netlink userland API, in particular with the LNet layer. The netlink API could also be used for lustre.</p> LU-9680

Improve the user land to kernel space interface for lustre

Improvement Major In Progress Unresolved James A Simmons James A Simmons Sun, 18 Jun 2017 18:11:30 +0000 Fri, 2 Feb 2024 15:33:08 +0000 Lustre 2.11.0 Upstream 0 17 <p>James, we already started working on a project to access module parameters and stats from sysfs. So we should coordinate that effort so we don't over write each other. I attached a requirements document I wrote that outlines what we plan to do for sysfs. Please take a look at it and provide feedback. My opinion is to use that as a starting point to plan out what needs to be done. thoughts?</p> <p>The first candidate for netlink usage has shown up from ticket <a href="https://jira.whamcloud.com/browse/LU-7659" title="Replace KUC by more standard mechanisms" class="issue-link" data-issue-key="LU-7659">LU-7659</a>. First it would be good to go over why I'm pushing Lustre to move toward netlink to fill in people like Yohn. The major reason is the data size limitation with ioctls. Some of the data reported by lustre overflows the size limitation such as stats. In the past the way around this was using proc which by using kernel seq_files allowing virtual unlimited size. With the move away from proc we end up in debugfs which only root is suppose to access. Second benefit is for I/O forwarding system which tend not to like ioctls.</p> <p>So the areas I was hoping to tackle with netlink are as follows:</p> <p>1) LNet seftest (<a href="https://jira.whamcloud.com/browse/LU-8915" title="Don&#39;t use linux list structure as user land arguments for lnet selftest" class="issue-link" data-issue-key="LU-8915">LU-8915</a>) which currently pass in kernel link list which is bad in many ways.</p> <p>2) lustre stats like md_stats so non-root users can collect stats.</p> <p>3) Replace the generic lustre ioctl interface we have. (<a href="https://jira.whamcloud.com/browse/LU-6202" title="clean up ioctl handling" class="issue-link" data-issue-key="LU-6202">LU-6202</a>)</p> <p>4) Use it to replace the HSM communication infrastructure. (<a href="https://jira.whamcloud.com/browse/LU-7659" title="Replace KUC by more standard mechanisms" class="issue-link" data-issue-key="LU-7659">LU-7659</a>)</p> <p>---------------------------------------------------------------------------------------------------------</p> <p>In the linux kernel their is only a limited number of core netlink services available. 32 to be exact and 22 have been taken. So lustre would need 2 since LNet is its own separate entity. It would be really hard press to get 2. What the kernel has done to get around this limitation is create a 'generic' netlink service. I would suggest we move to the interface. This way we don't need one netlink server in obdclass as well. </p> <p>Adding <a href="https://jira.whamcloud.com/browse/LU-7659" title="Replace KUC by more standard mechanisms" class="issue-link" data-issue-key="LU-7659">LU-7659</a> since the first implementation of netlink is being done.</p> <p>James Simmons (uja.ornl@yahoo.com) uploaded a new patch: <a href="https://review.whamcloud.com/34230" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/34230</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-9680" title="Improve the user land to kernel space interface for lustre" class="issue-link" data-issue-key="LU-9680">LU-9680</a> utils: add netlink infrastructure to liblustreapi<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: 30b2f9ee687f0521ac09278e56cf36b0e94b1a27</p> <p>Discussing with Amir and Olaf Weber the decision was to present all network collected data in YAML format.  With this approach we can actually piece together complex trees. One of things to come out of this is listing obd devices. With YAML output I have currently:</p> <p>devices:</p> <ul class="alternate" type="square"> <li>index: 0<br/>   status: UP<br/>   type: mgc<br/>   name: MGC10.37.248.114@o2ib1<br/>   uuid: 1a74da83-ca50-4<br/>   refcount: 4</li> </ul> <p>Would anyone want a different format? For me I think replacing index as the first field with the actual device name.</p> <p>Including the device name makes sense to me. Whether <tt>index</tt> as a separate field is worth retaining at that point is a different question. It depends on what consumers of this data will want to use it for.</p> <p>That is the beauty of netlink. You can transmit only what you want. This leads me to the idea of creating templates. I was planning on using this concept for stats and you gave me the idea that the template the user provide could take the ordering literally. So the ordering of the template fields that the user asked for can be used to create an YAML output tree in the same exact order. The other idea with this template approach is to also added filters so only under certain conditions will the data set be returned. For example we have the ioctl OBD_IOC_NAME2DEV. Here the filter would be the obd device name and the template would only request the obd index. </p> <p>Oleg Drokin (green@whamcloud.com) merged in patch <a href="https://review.whamcloud.com/34230/" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/34230/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-9680" title="Improve the user land to kernel space interface for lustre" class="issue-link" data-issue-key="LU-9680">LU-9680</a> utils: add netlink infrastructure<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: 3c39dac19aaf7f3f4fdee104ce6da92dd1962776</p> <p>Their is another patch outstanding.</p> <p>&gt; Would anyone want a different format?
