rdma-core soon in Debian

rdma-core soon in Debian

[Benjamin Drung]

Hi everyone,

a few weeks passed since my last status update regarding rdma-core in
Debian. We made good progress in getting it ready. Only three items are
left:

1) I sent three patches for the ibacm and iwpmd service to the mailing
list. They need to be reviewed and accepted:

$ git log --oneline master..bdrung
c3654500 ibacm: Add systemd service file
562d5a00 iwpmd: Support Debian/Ubuntu in sysvinit service
9744e8d2 ibacm: Fix service start_daemon call on Debian

2) Common infrastructure for auto loading rdma modules: See the "Add
rdma service for kernel boot support" thread on this mailing list.
Jason Gunthorpe made a very good proposal were I made some comments on
it.

3) Get rid of openibd and rdma service dependencies:

$ git grep openibd
ibacm/CMakeLists.txt:set(rdmascript "openibd")
srp_daemon/CMakeLists.txt:set(RDMA_SERVICE "openibd" CACHE STRING
"init.d file service name to order srpd after")
$ git grep rdma.service -- ibacm/
ibacm/ibacm.service.in:Requires=rdma.service
ibacm/ibacm.service.in:After=rdma.service opensm.service

openibd is not part of rdma-core and rdma.service will go away with the
 changes in point 2.


I expect to see progress on these points in the coming days / next
week. When all changes are in master, will we create a new release?
Otherwise I will have to base my upload on v14 and cherry-pick all
relevant changes.

It will be merged on Sunday, depends on lack of objections.

Usually, we are releasing rdma-core, a week or two after Linus's -rc1
release. Let's see how the progress will be and decide then.

I think Bart fixed most of these issues when he added systemd support,
so I recommend removing it from SRP for init.d as well.

No idea about what is wrong with ibacm that it needs this strange
ordering. Guessing we probably needs hotplug support in verbs to fully
make it work reliably, Yishia has patches for that pending..

Ideally we would make ibacm socket activate which will ameliorate most
boot time ordering issues even if there are still hot plug bugs in
ibacm..

This is done.

This is now PR 174.

Also, I tested the Debian packages in various way and all most of my
fixes are now commited.

These both relate to the init.d scripts,

AFAIK Debian is basically the only user of the init.d scripts, so you
should do whatever is appropriate. I think you can just drop both
references.

I will look at this next, I intend to make ibacm socket activatable,
which will take care of lots of ordering problems. verbs hot-plug (now
merged) and eventually rdma_cm hot plug should fix the rest.
