[LTP] [PATCH 0/3] quotactl ESRCH fixes

[LTP] [PATCH 0/3] quotactl ESRCH fixes

[Petr Vorel]

Hi,

simple cleanup to use already provided errno ESRCH handling.

Fortunately all tests which require do_mount() use
quotactl_syscall_var.h, thus I didn't have to introduce yet another
header.

Kind regards,
Petr

[LTP] [PATCH 1/3] quotactl: Move do_mount() to header

[Petr Vorel]

This allows do_mount() to be reusable in quotactl08.c and quotactl09.c.

Add inline keyword to it and to the other two functions (to follow LTP
convention).

Hi Petr

I doubt why fs quota is not supported on this case since we have check
kernel config?

I have no idea.
And yes, the config contains CONFIG_QFMT_V2=m

There is probably bug on the SUT, thus it might be correct it fails.

But how about martin's fix 4aab31e4c7 ("syscalls/quotactl: Skip tests if FS
quota is not supported") - quotactl04.c also checks for CONFIG_QFMT_V2 and uses
do_mount(). I'll check whether it was another bug on the system.

Maybe we miss check the following kernel config?
CONFIG_QUOTA=y
CONFIG_QUOTA_TREE=y
CONFIG_QUOTACTL=y

In my case it's probably a problem with mkfs.

Another possible way about loop driver. So do you use default loop image 
to create ext4 filesystem or export LTP_DEV?

FYI: in our case it was JeOS broken due missing quota_v2 kernel driver
(JeOS tries to be minimal, so it's always a fiddling between space and
functionality). I'm still not sure if we want to add check for .needs_drivers
quota_v2.

Kind regards,

In this case, kernel config says that quota is enabled as a module (=M).
But the module is packaged in a separate RPM and the test is running on
a minimalistic system where that RPM is not available. Therefore just
checking the kernel config is not sufficient. We need to query actual
module presence.

.needs_drivers would probably be the cleaner solution.

Sure - I'm closing this as wrong approach. I just wasn't sure if we want to
check for .needs_drivers. Because there could be numerous of other tests which
require test for missing driver. And it's relevant just fo JeOS like
installations, which strive for minimal size. BTW in our case it endup with
module added to kernel-default-base package (thus to be always installed).

Kind regards,
Petr

Oh, I replied the personal mail.

Thanks for your explaination. I don't know this complex situation before.

I think the quota module is belong to kernel-default package but not 
belong to kernel-default-base package. So jeos use kernel-default-base 
will pass kernel config check but indeed it miss this module.

This problem also occurs on centos if we use module from 
kernel-module-extra.

So a better solution is that if the module is belong to 
kernel-default-base ,then we can use kconfig check, but if the module is 
not belong to kernel-default-base, then use need_driver maybe more correct.
