[PATCH] rdma-core: Add missing systemd-devel dependency to the SUSE rdma-core.spec

[PATCH] rdma-core: Add missing systemd-devel dependency to the SUSE rdma-core.spec

[Tatyana Nikolova]

Without systemd-devel, all rdma-core daemons are using shim version of
systemd include file (in-turn, shim version of systemd functions)
causing them to not communicate with systemd.

Add the missing required systemd-devel package to SUSE's rdma-core.spec
so the correct header file is used and correct functions are linked
with the daemons.

You should not need that.
This is what this line is for:

 BuildRequires:  pkgconfig(systemd)

We don't expressly name systemd-devel and use the pkgconfig macro to allow building using systemd-mini-devel when needed.

I actually think pkgconfig(systemd) is a mistake in the spec file..

This brings in the libraries:

  BuildRequires:  pkgconfig(libsystemd)

This is does something else and isn't needed, AFAIK:

  BuildRequires:  pkgconfig(systemd)

Same with udev:
  BuildRequires:  pkgconfig(libudev)
vs
  BuildRequires:  pkgconfig(udev)

But you explained in the past suse needed actual udev installed for some
reason I can't remember..

> We don't expressly name systemd-devel and use the pkgconfig macro to

I suspect Tatyana has an old version of suse where
'pkgconfig(libsystemd)' doesn't do the right thing.

I suspect the issue is that old versions of suse probably have the old
arrangement of systemd libraries that were split into three libraries
(libsystemd-journal, libsystemd-id128, and libsystemd-daemon)
so pkgconfig(libsystemd) isn't going to work (and rpmbuild should fail
fail, why doesn't it??)

Probably something like

BuildRequires:  pkgconfig(libsystemd) | (pkgconfig(libsystemd-journal), pkgconfig(libsystemd-id128), pkgconfig(libsystemd-daemon))

If RPM can do that, otherwise a suse version conditional?

This was requested by the main OpenSUSE maintainer so I blindly trusted him with this :)
I'll still ask him if both are really needed (and if yes, what's the diff)

Our build systems checks that scriptlets call existing binaries.
Without udev, udevadm does not exists which gets some errors in the build logs.

The current works with version down to SLE12. I doubt anyone would run rdma-core on older releases as it very ancient.
Tatyana, could you give some more info on what prompted this patch ?

Version conditionnal is better. But I'd like to know what the exact problem is before tweaking that.

rdma-core is at the middle of huge build dependencies that involve systemd, boost and a bunch of other stuff. I have to be very careful with these dependencies not to mess everything up.

I would anticipate this is the reason:

  Our build systems checks that scriptlets call existing binaries.
  Without udev, udevadm does not exists which gets some errors in the
  build logs.

As we also call systemd binaries in various places.

The patch was prompted when the rdma-core daemons were unable to start on a SLES12SP2 system, because the shim version of the systemd functions were used instead. Unfortunately I don't have the details on how rdma-core was installed on this system.

Checking the current SUSE spec file on the same system (without systemd-devel installed), it indeed detects a missing dependency:
"error: Failed build dependencies: pkgconfig(libsystemd) is needed by rdma-core-15-0.x86_64"

However libsystemd packages (libsystemd0-228-117.12.x86_64 and libsystemd0-32bit-228-117.12.x86_64) are installed on this system, but systemd-devel is necessary to install the required headers, for example "sd-daemon.h" needed by the daemons. 

Maybe it would be better to replace pkgconfig(libsystemd) with pkgconfig(systemd-devel) in the spec file, since systemd-devel requires libsystemd?

Thank you,
Tatyana

Well, are you even sure it was built with rpmbuild?

Because rpmbuild shouldn't have succeeded, right?

Yes, that is right. But pkgconfig(XXX) is a magic notation to 'bring
in -devel packages for XXX'

So pkgconfig(libsystemd) is supposed to bring in systemd-devel, for
instance.

You'd need to reproduce a failing rpmbuild where the deps are met and
the shims are used to understand this issue..

I just checked:
This pulls in systemd (or systemd-mini)

And pkgconfig(udev) pulls udev or udev-mini.
So they are not compulsory build requirements (as we require the -devel they should be installed by dependency) but they don't hurt.

On a recent systemd, systemd-devel provides all those (probably for compat reason during migration):
$ rpm -q --provides systemd-devel
pkgconfig(libsystemd) = 228
pkgconfig(libsystemd-daemon) = 228
pkgconfig(libsystemd-id128) = 228
pkgconfig(libsystemd-journal) = 228
pkgconfig(libsystemd-login) = 228


So I can porobably safely changes the BuildRequires to the libsystemd-XXXX.
If I'm not mistaken, we just need the -daemon and -journal ones.

If you don't mind me asking, why are you trying to do this on SLE12SP2 ?
SP2 is using now ancient libraries from OFEd (pre rdma-core).
Even it compiled right for SP2, I have very strong doubt about the system being fully working unless you recompile all IB related RPMs...

I strongly advise doing this from a SLE12SP3 which uses rdma-core v14.

cmake checks for all id128 as well when it runs in compat mode, so you
need all three to make it happy.

I wouldn't change the main spec file, maybe protect the 2nd option
with a ifdef for old suse versions?

I don't really mind either way.

However is there any chance that it will work ?
I'm pretty sure there are some (if not many) ABI changes from ibverbs 1.2.0 to rdma-core v16.
This means that all dependent packages needs to be rebuilt, and some probably updated too.

>From my SUSE package maintainer perspective, that is something that should not be done and SUSE will not provide any official support for that.
Regarding upstream we can't really forbid people to do this, just try to point them in a "sane" direction :)
