An invalid extent inline ref type could be read from a btrfs image and
it ends up with a panic[1], this set is to deal with the insane value
gracefully in patch 1-2 and clean up BUG() in the code in patch 3-5.
Patch 6 adds scrub support to detect the corruption, so users can be
noticed when they do scrub on a regular basis.
I'm not sure in the real world what may result in this corruption, but
I've seen several reports on the ML about __btrfs_free_extent saying
something was missing (or simply wrong), while testing this set with
btrfs-corrupt-block, I found that switching ref type could end up that
situation as well, eg. a data extent's ref type
(BTRFS_EXTENT_DATA_REF_KEY) is switched to (BTRFS_TREE_BLOCK_REF_KEY).
Hopefully this can give people more sights next time when that
happens.

An invalid value of extent inline ref type may be read from a
malicious image which may force btrfs to crash.
This adds a helper which does sanity check for the ref type, so we can
know if it's sane, return type if so, otherwise return an error.

Since we have a helper which can do sanity check, this converts all
btrfs_extent_inline_ref_type to it.

Now that btrfs_get_extent_inline_ref_type() can report if type is a
valid one and all callers can gracefully deal with that, we don't need
to crash here.

btrfs_print_leaf() is used in btrfs_get_extent_inline_ref_type, so
here we really want to print the invalid value of ref type instead of
causing a kernel panic.

Currently scrub only verify checksum of both metadata and data and
couldn't detect an invalid extent_item.
This adds sanity check for extent item, now it can check if
extent_inline_ref_type is valid.

Can you change those numbers to either #defines or better an enum type?
Looking at one call site the last argument being a number says nothing
and one has to context switch to the function definition. E.g. from
patch2 :
*out_type = btrfs_get_extent_inline_ref_type(eb, *out_eiref, 2);
possible names:
BTRFS_BLOCK_REF_TYPE
BTRFS_DATA_REF_TYPE
BTRFS_ANY_TYPE

Can we please keep the namespace, BTRFS_ANY_TYPE is way too generic.
Suggested: BTRFS_REF_TYPE_BLOCK, BTRFS_REF_TYPE_DATA,
BTRFS_REF_TYPE_ANY.

And to let the function return the enum, add BTRFS_REF_TYPE_INVALID with
value 0.

I don't see is_data used anywhere, also not in the followup patches.
Please use a bool type in case it's valid here.

Would be good to extend the error message, also in the previous patch.
Print inode number, root id and the (invalid ref) type.

This is a different kind of check that scrub was never designed to do.
Scrub just verifies the checksums, not the sructural integrity. This has
been referred to as an "on-line fsck". AFAIK xfs does not use 'scrub' in
the same sense as btrfs, so things are going to be confusing for the
users.
The on-line fsck is still desired, but I'd like to see a discussion how
exactly it should work, whether to extend scrub or add a new ioctl etc.

Yeah, this is an example where the uncorrectable_error would gain a new
meaning. We'd need to extend the scrub error reporting so the various
metadata errors get reported properly and not mangled with the rest.

Good catch, I should remove is_data since it uses the original
btrfs_extent_inline_ref_type directly, will update it.

I've printed out the whole leaf's content in the helper
btrfs_get_extent_inline_ref_type if type is not valid, and it shows
the invalid ref type.
For inode number and root id, it's not available in this relocation
case, I'll check that in other patches.

I was hesitating about scrub vs online fsck when posting, just thought
it'd be good when users got this error while doing a regular scrub
ahead of really getting into trouble. If we have a plan for online
fsck, I'm happy to let fsck do the job.
Or we can do this kind of sanity check at the time when reading the
eb.

IIRC on-line fsck will be too challenging for kernel.
Just check how current btrfs check does, it's doing tons of cross
checking for lowmem mode or uses tons of memory to record forward refs
and backward refs.
Doing it in kernel will be a disaster.

This seems more reasonable, just like what Su Yue did for
inode_ref/dir_item/dir_index.

Ok, we should define what's considered a sane 'fsck' subset that can be
done in kernel.

Full cross-ref validation is obviously quite heavy in terms of memory
resources and potential impact on the filesystem work.

Yeah that's what I had in mind, local sanity checks from information
available at the time. We can add such check independently and not
caling them on-line fsck anyway, so we can avoid overloading the scrub
stats.

I've caught this type of corruption in the wild. The big rsync backup
always ends with a kernel crash due to BUG() statement in
ctime.h:1779. After applying this patchset and running scrub I've got
following messages:
[sivan@fruestuck ~]$ dmesg | grep "invalid extent inline"

How to find the cause of the corruption? Should I try to fix it, or it
is not dangerous for the filesystem? If I should, how to do that?

Did it also print a btree's leaf's content? If yes, it could show us
which inline ref has the issue.
It's not easy to tell if it's dangerous because I have no idea what
type of extent "2994741559296(0x2b94481c000)" refers to.
The command 'btrfs check' in the latest btrfs-progs can fix my test
case, which is the simplest one (only touched the inline ref and
everything else remained the same).
Given that at least two users reported about this, I start thinking
about there's something wrong inside our btrfs code.

After I went through the output of leaf's content, most parts of the
leaf is sane except the two corrupted items, it's still not clear to
me what caused the corruption, there could be some corner cases that
I'm not aware of.
If fsck doesn't work for you, then a recovery from backup may be the
best option.

I don't need to run any repair procedures because system is working
normally. Most likely that corrupted extents belong to files located
somewhere in /home.
Do you mean I should run fsck in order to determine which files are
corrupted? What are proper options to run fsck with?

I see. Scrub has found that there are some corrupted metadata, if you
want to fix that corrupted thing, fsck may be helpful. Due to my
test, 'btrfs check /your_disk' fixed my corruption.
With this patch set, at least you won't get a crash when accessing the
corrupted extent inline ref.

After applying patchset I unwisely ran rsync and then FS became RW-unmountable.
"btrfs-check -p --readonly" gave me many errors of different types.
After "btrfs check -p --repair" I'd mounted the FS and ran scrub.
But not all errors was fixed and boot attempt caused RO-remounting again.
Now check gives this:
[liveuser@localhost-live ~]$ sudo btrfs check -p --readonly /dev/sda1

How to fix it? Can "btrfs-check --repair --init-extent-tree" help?
P.S. I ran all the commands from Fedora 26 Alpha Live disk with kernel
4.11.0-0.rc3.git0.2.fc26.x86_64 and btrfs-progs v.4.9.1
