8 years agobtrfs-progs: add validation checks for chunk loading

btrfs-progs: add validation checks for chunk loading

To survive fuzz filesystem images, we need various validation checks to
make btrfsck detect any invalid value inside chunks including those in
 sys_array.

Note that these checks may not be sufficient to cover all corner cases,
we may need to add more later.

This also refractor previous various checks into a helper function so
that we can add more checks into it in the future.

btrfs-progs: fsck: Fix a false metadata extent warning

At least 2 user from mail list reported btrfsck reported false alert of
"bad metadata [XXXX,YYYY) crossing stripe boundary".

While the reported number are all inside the same 64K boundary.
After some check, all the false alert have the same bytenr feature,
which can be divided by stripe size (64K).

The result seems to be initial 'max_size' can be 0, causing 'start' +
'max_size' - 1, to cross the stripe boundary.

Fix it by always update extent_record->cross_stripe when the
extent_record is updated, to avoid temporary false alert to be reported.
