[PATCH] xfstests: xfs mount option sanity test

[PATCH] xfstests: xfs mount option sanity test

[Zorro Lang]

XFS is changing to suit the new mount API, so add this case to make
sure the changing won't bring in regression issue on xfs mount option
parse phase, and won't change some default behaviors either.

This looks great, it looks quite comprehensive.

I'll give it a try once I've done the recently requested changes
to my mount api series and let you know how it goes.

Presumably the test passes when using the current master branch of
the xfs-linux tree, correct?

This case test each xfs mount (not include rtdev) option one by one, but didn't
test their combination. If you think testing option combination is necessary,
I'll write another case to do that, as this case is big enough.

I tested on latest RHEL-8, and test passed. I'm doing more test on old(RHEL-7)

Re: [PATCH] xfstests: xfs mount option sanity test

I remember xfstests has a case xfs/191-input-validatio to test mkfs.xfs 
various behaviors. This case looks similar to xfs/191-input-validation.
But xfs/191 is not worth updating because it needs to update every time 
if mkfs.xfs changed. mount action has the same problem.

This case tests xfs mount options(refer to man 5 xfs), focus on xfs_parseargs(),
not mkfs.xfs itself.

I think this isn't quite right:

Above logbufs and logbsize are present in the options string but
an error is reported.

Oh, There're two reasons to cause this failure:
1) I made a mistake at here:
        if [ $rc -eq 0 ];then
                if [ "$found" != "true" ];then
                        echo "[FAILED]: mount $LOOP_DEV $LOOP_MNT $opts"
                        echo "ERROR: expect there's $key in $info, but not found"
                        return 1
                fi
        else
                if [ "$found" != "false" ];then
                        echo "[FAILED]: mount $LOOP_DEV $LOOP_MNT $opts"
                        echo "ERROR: expect there's not $key in $info, but found"
                        return 1
                fi
        fi

I should exchange the "there's" line with "there's not" line.

2) The case expect there's not "logbufs=N" or "logbsize=N" output as default.
But your system has these two options in /proc/mounts if mount without any
options.

Hmm... strange, I've tested this case on rhel8 and rhel7, all passed. Where
can I reproduce this error?

Thanks,
Zorro

There's every chance this has changed along the way but the current
upstream source sets these two fields to default values at some
point (looks like via xfs_mountfs() from xfs_fs_fill_super() to me).

So the super block op ->show_options() sees them as > 0 and prints
the option in the proc output.

But I'm not so familiar with xfs so the subtleties of these options
eludes me.

Dave, can you help out please wrt. current RHEL xfs or what I'm
missing here?

Oh, I see what's going on.

In, for example, RHEL-8 xlog_get_iclog_buffer_size() on entry we
have:

        if (mp->m_logbufs <= 0)
                log->l_iclog_bufs = XLOG_MAX_ICLOGS;
        else
                log->l_iclog_bufs = mp->m_logbufs;

which sets a struct xlog field but leaves the struct xfs_mount
alone.

But upstream on entry we have:

       if (mp->m_logbufs <= 0)
                mp->m_logbufs = XLOG_MAX_ICLOGS;
       if (mp->m_logbsize <= 0)
                mp->m_logbsize = XLOG_BIG_RECORD_BSIZE;

which sets the struct xfs_mount fields before continuing.

There's a lot more going on in xlog_get_iclog_buffer_size() so this
is a very simple minded comparison on my part but the point is
RHEL-8 (and I'm assuming RHEL-7 too) is different to the current
xfs upstream.

So I'd still like more info around this difference please Dave.
Apologies for the post beer-clock intrusion, ;)

Ok, more info., first see commit 1cb51258758d7:

Author: Eric Sandeen <sandeen@sandeen.net>
Date:   Thu Aug 16 16:24:43 2007 +1000

    [XFS] choose single default logbuf count & size

and then commit 4f62282a36964:

Author: Christoph Hellwig <hch@lst.de>
Date:   Fri Jun 28 19:27:20 2019 -0700

    xfs: cleanup xlog_get_iclog_buffer_size

which is where the change occurred.

I think this last change is what's causing the difference in
behaviour.

I'm not certain but I think the file system behaviour is the
much same but current upstream is simplified.

I think that a pass should be either option not present or
option is present and set to default (for example logbufs=8)
when the option is not given.

Not sure that's simple to do but would probably be the best
way to deal with it.

I expect Dave knows what the implications of upstream changes are
and sets back port priorities accordingly so I'm not sure a bug
against RHEL xfs is the right way to go. And older RHEL releases
are less likely change (assuming this change doesn't have serious
implications) but we still need to perform QA testing on them.
