[LU-10391] LNET: Support IPv6

• Status: Reopened
• Project: Lustre
• Fix Version/s: Upstream, Lustre 2.16.0
• Type: New Feature
• Priority: Major
• Reporter: Doug Oucharek (Inactive)
• Assignee: Neil Brown
• Resolution: Unresolved
• Labels: IPv6, lnet, upstream

Description

This improvement calls for fully supporting IPv6 throughout LNet and the LND's. This will allow Lustre to run in IPV6 networks, in conjunction with related changes to any configuration and PtlRPC changes where NIDs are processed (e.g. config llog records, Imperative Recovery, etc.).

Comments from Multi-Rail HLD https://wiki.whamcloud.com/pages/viewpage.action?pageId=31073572 :

One proposal was to create an incompatible IPv6-capable network protocol, simply by increasing the field size at compile time and have separate LND types for the new protocol. Those sites that can't just switch entirely over to the IPv6 protocol could use LNet routers to translate messages between the protocols as needed. Of course, the longer this is delayed, the more sites will be affected.

In any case, increasing the field size here is trivial before implementation and the fewer places that need to be fixed in the future, the better, especially when dealing with userspace interfaces.

The main issue is NIDs, which are 64 bits, with only 32 bits reserved for the node interface id.

The MGS could just assign a 32 bit ID, if there were something like the MGS. But there isn't, so it can't. (In contrast, CXFS has a cellid concept separate from any IP address or other identifier, so when we did IPv6 support the work really was limited to the network layers and configurationhandling.)

For this work I'd really like to have some node ID separate from IP address (or whatever), as it would help resolve some edge cases. I'm just not seeing an easy way to add it and retain backward compatibility. And anything complex in that area becomes a beyond-scope issue...

For lnet_ping_info_t it seems fairly straight forward to set a new LNET_PING_FEAT_IPV6 flag in pi_features and then have a new lnet_ni_status32_t with a new lnet_nid32_t large enough to hold a 128-bit IPv6 NID.

There is a separate problem of the other uses of lnet_nid_t in the protocol, but if we can get the initial handshake to exchange support for larger NIDs then the rest of the messages can follow suit.

That said, IPv6 support is way beyond the scope of the multi-rail implementation. My main goal is to ensure that we don't put any more roadblocks in the way of implementing that, especially in initial connection establishment messages like PING and PUSH. If anything else can be done to make the LNet protocol "more accepting" of IPv6 NIDs in the future (e.g. better protocol feature exchange at connection time), that would be welcome.

For the ping_info, a feature flag could indicate a separate header following the current pi_nid[] array, specifying the number of the new-format NIDs. A downrev node would ignore that part of the data.

It would also be possible to use a different match bit for a new-style ping request. That way a downrev node would not be seeing the new form at all.

I like the idea of adding the IPv6 (or other larger-format addresses) after the regular lnet_nid_t addresses, since that avoids sending larger packets in the case where it is not needed.

For socklnd, I see it might be possible to change the ksock_hello_msg_t.kshm_version and lnet_magicversion_tactually be a bitfield of features rather than a numeric version number. In particular, version_major and version_minor are described as compatible and incompatible "versions" but they could be bitfields as well (equivalent to incrementing the version in power-of-two values for old clients that don't understand the feature flags).

My goal for projects like this is to try and lay the groundwork early on, if possible, and then when it comes time to implement the feature (maybe a few years/releases later) it can be done in a way that doesn't cause so many problems for older clients.

At socknal level you'd likely use a new ksock_hello_ipv6_msg_t. At the point where you're sending it, you know for certain whether you're talking over IPv4 or IPv6.

And (hypothetically speaking) the multi-rail work should render obsolete the reason for ksocknal to send IP addresses in its hello message.

[Andreas Dilger]

This ticket isn't due to any specific requirement for this feature, but just to preserve discussion/brainstorming on this topic in case it is needed in the future. IPv6 support is definitely something to keep in mind as other changes are being made in the LNet layer.

[Neil Brown]

My design for this change is to introduce a new "struct lnet_nid" which has room for 16 bytes of address.

This will then be gradually spread throughout the code replacing 'lnet_nid_t' which will eventually be deprecated.

Where lnet_nid_t is often passed to functions, and returned, by value, 'struct lnet_nid' is larger and will be passed or returned by reference.  This change in particular means that it is easiest to change the type gradually, rather than trying to prepare all the code to allow "lnet_nid_t" to be atomically changed to a larger size.

Where possible, we change the arguements to a function from old to new style.  Sometimes we need to keep both old-style and new-style functions available concurrently.

When this happens I have used two approaches to naming.  If there are relatively few uses of the function, the old one is renamed to have a "_4b" suffix (because it supports addresses with a 4-byte address), and the name is then used for new-style format.  When there are too many uses for this to be practical, a new name which is spelt slightly differently is used.  e.g. libcfs_nid2str becomes libcfs_nidstr.  This will probably cause confusion during the transition, but the compiler will easily warn about any such confusion.

I plan to submit patches (I currently have 35, but there is quite a lot more work to do) in smallish batches over coming weeks - depending on review feedback.

[James A Simmons]

In the interop testing 2.12.7 is being used which always fails racer for RHEL7. A fix has landed to 2.12.8. Can someone bump the version the interop testing is being done against. Thanks.

[Andreas Dilger]

That will happen when 2.12.8 is released.

Neil using my Netlink patch I attempted to bring up an IPv6 NID but it failed. Looking at ksocklnd it's still hardcoded to ipv4. Could you update the LND driver while I work on the Netlink ping patch.

With the ksocklnd patches and my Netlink work I can bring up IPv6 interfaces.

lctl list_nids
fe80::f68:45bd:7b60:e933@tcp

I also created a Netlink ping patch and testing pinging with IPv6. I'm seeing

This is ping the local NID and a remote NID.

Can't help with the LNet part, but please update theIPv6 NID printing to use the standard shortcut to skip blocks that are all-zero:

[Neil Brown]

> but please update theIPv6 NID printing to use the standard shortcut to skip blocks that are all-zero:

What are there two struct netstrfns libcfs_netstrfns[], one in libcfs and one in lnet?

The one in lnet will get this right, the one in libcfs doesn't - because I didn't realise there were two and that I needed to extend them both.

 

[Andreas Dilger]

It looks  like  one for  the kernel and one for the userspace utils.  These functions used to be shared between the kernel and userspace, but they were split into two separate copies in commit v2_7_51_0-30-g05d13ca333:

LU-6245 libcfs: create userland and kernel string operations
    
Additonal string handling and NID string parsing code are both
used by kernel space and user land. This prevents us from
moving forward for cleaning up the userland and kernel space
headers. With the code duplicated for both environments we
can then clean up the headers independently. Since NID string
handling is only done for LNET we move it there.

At a minimum, it would make sense to add a comment to both copies of this struct reporting on its peer's existence, and possibly have some sanity checking for consistency.

[Neil Brown]

Sorry - I didn't realise that the libcfs was in the user-space libcfs, not the kernel-space one.  That makes more sense.

So I've looked at the problem again and now see that I misunderstood it.  The IPv6 address stored in a nid IS being formatted correctly by libcfs_strnid().  The problem is that when an address (not in a NID) is being reported in the error message, it has the less desirable format.

This can be fixed by using %pIScp rather than %pISp for reporting network addresses.  The 'c' means compressed, and is ignored for IPv4.

[James A Simmons]

Status update:

One LNet core patch is outstanding. We have code to handle sending new LNet headers for bulk I/O  but its not available to send over the wire when using a large NID. Once we have that in place we can send data between two IPv6 based NIDs. I'm working on more Netlink code to allow us to use the new large NIDs for user land APIs. I just pushed LNet selftest group querying handling to Netlink. The last bits for lnetctl / lctl ping for large NIDs is almost done. After that LNet peer support for large NIDs will be added.

[Andreas Dilger]

James, has any effort been spent on the Lustre side of this equation yet (LU-13307, LU-13308, LU-13340, LU-14288)?

Getting some of these issues addressed (in particular the basic config llog and Imperative Recovery records) to allow IPv6 addresses in the logs (even if the clients don't know how to connect to them yet) would avoid interoperability issues with older clients seeing these larger records. It would great if something could be included into 2.12.10 (which will be the end of the line for 2.12 releases) to maximize the backward compatibility.

[James A Simmons]

I like to get traffic flowing between LNet nodes first. I really want to make sure we get Lustre support right.

If we can get LU-10360 working then Lustre can bring up LNet itself without any user configuration.  This setup could be a way to test Lustre with IPv6 without the need for LNet utilities being totally updated.

what is the staus of the overall Lustre/LNet IPv6 support? Is it ready for prime time?

I am working on a tender (100 PB, 1.25 GB/s, HDR or NDR InfiniBand) that requires IPv6.

Greetings,
Bjoern

[Neil Brown]

IPv6 support is getting close to the point where we might be able to start testing some bits of the new code.
The LNET side might be mostly functional in the near future.

We are still quite a way before we could think about trying to mount a Lustre filesystem using IPv6.

So no - not ready for prime time yet.

 

[Bjoern Olausson]

Thanks Neil,

is there a rough ETA?

[James A Simmons]

I plan to push all the LNet user interface changes needed to support IPv6 to the repo by the end of the month. It will take time to review and merge the patches. Currently I'm working on regression found with multi interface nodes and then I have a few patches out standing to collect peer and router information. I also pushed a patch for managing peers but it needs an update. What is missing is full collecting of the LNet NI (lnetctl net show) and managing the routes. That should cover most of tools for LNet with IPv6. LNet selftest is still in the works.

How much do you need done to start your testing? 

P.S    I do want to aim at getting AF_IB support going as well before the close window of this release.

In patch https://review.whamcloud.com/#/c/fs/lustre-release/+/49516 Oleg has reported an __might_sleep. I believe this to be a bug in the RHEL7 kernel where it is lacking a fix (git commit 707693c8a498697aa8db240b93eb76ec62e30892). I have asked Oleg to try the IPv6 patch out with a RHEL8 debug  kernel or perhaps patch his debug kernel with the mentioned patch to see if it resolves it. If does come to this issue I can open a ticket with RedHat to have the patch applied to its RHEL7 kernels.

I've filed LU-16738, which relates to how the mount.lustre command can be improved for multiple NIDs on the command line. While it is useful for systems today, I think it will be increasingly important for IPv6 due to the longer NID length.

My latest batch of LNet IPv6 work went without a review for 3 weeks outside of Chris Horn. Has this work been slated for the 2.17 release?

[Andreas Dilger]

I was away for ISC and two weeks vacation, so didn't do (m)any patch reviews during that time, but I'd hope that Neil or Serguei or Frank would have done reviews on at least the first patches in the series to keep it moving along in my absence.

[Mikhail Pershin]

the patch "LU-10391 obdclass: handle large NIDs for mount strings" caused my local system stops to mount servers with error like this:

[11210.421883] LNetError: 120-3: Refusing connection from 192.168.56.101 for 0.0.0.0@tcp: No matching NI
[11210.423194] LNetError: 122557:0:(socklnd_cb.c:1783:ksocknal_recv_hello()) Error -104 reading HELLO from 192.168.56.101
[11210.424063] LNetError: 11b-b: Connection to 0.0.0.0@tcp at host 0.0.0.0:988 was reset: is it running a compatible version of Lustre and is 0.0.0.0@tcp one of its NIDs?

the reason was that my hostname listed in '/etc/hostname' was not listed in '/etc/hosts' with related address. I am not sure that is correct solution for the problem because without that patch it worked, so problem occurred due to patch and I suppose it should be  fixed in patch as well. Anyway, if there will be a report about 0.0.0.0@ address that can be fixed by listing hostname in /etc/hosts

[James A Simmons]

The change was the move from gethostname() which only supports IPv4 to getaddrinfo() which supports both IPvv4 and IPv6. What did your /etc/hostname look like so I can reproduce this. I suspect your /etc/hostname lacked an actually IP.

[James A Simmons]

Ah to support what you want you need to install the package containing nss-myhostname. Try that and let me know if it works. 

[Mikhail Pershin]

James, I had the following in configs:

[root@nodez ~]# cat /etc/hostname 
nodez
[root@nodez ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.56.101   nodez <--- this one was added later
[root@nodez ~]# 

The last line in /etc/hosts was added to fix the issue. Without it the address of nodez was reported as 0.0.0.0

I have no nss-myhostname tool in my Centos 8 and didn't figure out yet what package contains it. Any ideas?

[James A Simmons]

Pushed the 3 needed patches required that we need to allow mounting Lustre with IPv6. Something kind of works but its unknown what is lacking with testing. I have shorten IPv6 address so I haven't seen the UUID overflow just yet. That needs to be fix but it works in general.

[James A Simmons]

Status update:

Patch https://review.whamcloud.com/c/fs/lustre-release/+/53117 is in master-next and ready to land. The other patch needed for mounting lustre with IPv6 is https://review.whamcloud.com/c/fs/lustre-release/+/53135 which is currently being actively worked on. With this work we can be considered feature complete.

Addition work is needed and for more complete LNet setup support we need 3 patches:

https://review.whamcloud.com/c/fs/lustre-release/+/49361

https://review.whamcloud.com/c/fs/lustre-release/+/53003

https://review.whamcloud.com/c/fs/lustre-release/+/53004

Those patch are WIP but they mostly work for me. Bugs are being worked out.

Status report:

For basic support for mount and using lustre with IPv6 we are done to one patch needed to mount. That is patch https://review.whamcloud.com/c/fs/lustre-release/+/53135.

As you can see we have a bunch of patches to make testing pass.

I've pushed a revert for the most recent patch in this ticket because it is causing almost constant failures since 2024-01-03 when it landed (build version 2.15.60.1). Almost all of the PASS results since that date are for patches that have not yet rebased:

[James A Simmons]

It might be good to expect the test for now. It doesn't fail all the time so I suspect its a timing issue with the test.

[Andreas Dilger]

It doesn't fail all the time so I suspect its a timing issue with the test.

It fails about 90% of the runs since the patch landed, so it should be possible to debug fairly easily.

The recent patch about GFP_ATOMIC doesn't have anything to do with this sanity-lnet failure, but just fixing a longstanding problem in lnet_discover() that shows up in Gerrit Janitor testing.
