2 patches here:
First of all, "return" is not a function. "return(EIO);" is silly.
"return (EIO);" is even sillier. Stop it.
Second of all, XFS_ERROR was designed long ago to trap return values,
but it's not runtime configurable, it's not consistently used,
and we can do the same thing today with systemtap.
So nuke that macro, too.
This is a *lot* of churn. It'll make merging across this change hard.
So we might want to batch this up with another suggestion of Dave's,
to migrate all of xfs to the Linux convention of negative error
returns everywhere, so we don't have two nasty points to merge
across - that'd be fine with me. But anyway, here it is for now.
For posterity, the first patch was generated with:
perl -p -i -e 's/return \(([a-zA-Z0-9]*?)\)/return $1/g' *.c
perl -p -i -e 's/return\(([a-zA-Z0-9]*?)\)/return $1/g' *.c
and the 2nd with:
perl -p -i -e 's/return\(XFS_ERROR\(([a-zA-Z0-9]*?)\)\)/return XFS_ERROR($1)/g' *.c
perl -p -i -e 's/return \(XFS_ERROR\(([a-zA-Z0-9]*?)\)\)/return XFS_ERROR($1)/g' *.c
(Yes, I know I could have done it w/ one regexp - so sue me) ;)
-Eric

return is not a function. "return(EIO);" is silly;
"return (EIO);" moreso. return is not a function.
Nuke the pointless parens.

From: Eric Sandeen @ 2014-04-16 17:48 UTC (permalink / raw)
To: xfs-oss
XFS_ERROR was designed long ago to trap return values,
but it's not runtime configurable, it's not consistently used,
and we can do the same thing today with systemtap, using
something like:
probe module("xfs").function("xfs_*").return { if (@defined($return) && $return == VALUE) { ... } }
Just nuke XFS_ERROR and associated bits.

Gives me a version just using ftrace, or at least a kprobes based module
that we can merged in the kernel tree and this would be fine for me.
Requiring a massive blob of questionable out of tree module code and a
compiler is an absolute no-go.
NAK for now.

Ok, fair point.

Even if we don't have a replacement, I have yet to find anyone who has
ever used it...
Anyway, I'll look into options besides systemtap.

Steve, we want to be able to trap specific return codes from
functions. Say, for example, the first function that returns
EINVAL/-EINVAL in XFS under a given workload.
What's the most efficient way to do that with ftrace?
And can that be set up as a trigger so we can use it to dump a
snapshot of the last N events into the trace buffer or do other
interesting things with that event?
Cheers,
Dave.

I think regardless of the systemtap/ftrace replacement, nobody uses
this at the moment, and it's not been used for a long time. It's a
compile time configurable, debug only error trap that is far
less useful than adding printk() or tracepoints at the appropriate
points.
If you've got to recompile the kernel to use it, then you may as
well add meaningful debug rather than hope an error trap that panics
the kernel tells you what you need. i.e. the error trap code as it
stands is only useful for those running kernel debuggers, and very
few developers actually do that these days.
And, FWIW, it only allows detection of then initial error instance -
too bad if you want the second or third occurrence of the error.
IOWs, I can't see how this is at all useful anymore....
Cheers,
Dave.

BTW, it's usually better to do:

Well, after you do the above, you could also do a while loop to all
those events and update the filter:
echo 'arg1 > 0xffffffffffffff00' > /debug/tracing/events/kprobes/filter
Which would trace only those functions that had an error code (assuming
the error code is less than 256). You could also use the trigger files:
echo 'traceoff if arg1 > 0xffffffffffffff00' > /debug/tracing/events/kprobes/*/trigger
The above wont actually work as is, you would need to do another while
loop of trigger files and set them each individually.

so, basically a script that does:
#!/bin/bash
TRACEDIR=/sys/kernel/debug/tracing
grep -i 't xfs_' /proc/kallsyms | awk '{print $3}' ; while read F; do
echo "r:ret_$F $F \$retval" >> $TRACEDIR/kprobe_events
done
for E in $TRACEDIR/events/kprobes/ret_xfs_*/enable; do
echo 1 > $E
done;
echo 'arg1 > 0xffffffffffffff00' > $TRACEDIR/events/kprobes/filter
for T in $TRACEDIR/events/kprobes/ret_xfs_*/trigger; do
echo 'traceoff if arg1 > 0xffffffffffffff00' > $T
done
And that gives:
# dd if=/dev/zero of=/mnt/scratch/newfile bs=513 oflag=direct
dd: error writing ¿/mnt/scratch/newfile¿: Invalid argument

Which is precisely the detection that XFS_ERROR would have given us.
Ok, so I guess we can now add whatever need need to that trigger...
Basically, pass in teh XFs function names you want to trace, the
sets up teh events, whatever trigger beahviour you want, and
we're off to the races...
Cheers,
Dave.

FWIW, this strikes me as something that would be useful for
trace-cmd to be able to control, creating the kprobes dynamically
based on the function name specification given on the command
line similar to how we specify the events we want it to trace..
I'm sure there's more people that just us that want to know what
function a specific error first comes from and how it propagates
back up through the code....
Cheers,
Dave.

This looks incredibly useful! Can we throw this into Documentation/ as
a helper script (and make the xfs a command line parameter so it's
genericly useful)?
One think that would be nice is to specify a module instead of relying
on a clean namespace, but to replace the XFS functionality the one above
is more than enough.

So does that mean you have no more objections to removing
XFS_ERROR()?
The thing is, that's a quick hack that spews errors all over the
place, especially if you run it twice. It needs a counterpart to
turn off the tracing, clean up the triggers, etc....
FWIW, what I'd really like is a trace event trigger that triggers
a BUG(), so that we can use it to drop into kernel debuggers or get
kdump to generate a core that can be analysed offline...

My current hack is invoked like this:
$ grep -i 't xfs_' /proc/kallsyms | retval_filter.sh
Makes it completely independent of how you supply the symbols to the
function. Hence my coments about how it'd be really cool to have
this built into in trace-cmd, because the mechanism is independent
of how you specify the function list...
Cheers,
Dave.

Eric, given the rebasing impact of this change on other pending
work, I think we should plan to merge this just prior to the next
upstream merge. Perhaps regenerate it against the for-next branch
a week before the merge window is likely to open, and then apply
it? That way we (well, I) don't have to spend a alrge proportion of
this merge window fixing up patch mismatches vs the master branch?
Is that an acceptible approach for everyone?
(Note: I'm assuming Christoph is OK with this given the ftrace
scripts we can use to replace this macro...)
Cheers,
Dave.
