v5.7-rc2-1174-gfd4f12bc38c3 significantly rewrites the bpf iterator
which hits this _next() function. It also adds a check that verifies
that the *pos is incremented after every call, even if it goes beyond
the last member (in which case it's not used).

v5.11-rc4-7-g2f221d6f7b88 Changes setattr_prepare from an extern
to plain int. There's no impact further to the compat to keep it
working except for the detection regex.

We could use sizeof_field as a direct replacement (which is the same)
except that this entire thing can directly use offsetofend().

The wrapper in setattr_more that translates the operations to attr_x
needs to decide whether to ask attr_x to perform a change to any of
the fields passed to it or not. For the date and size fields this
is implicit - we always tell attr_x to change them. For any of the
other fields, it should be explicit.
The only field that is in the struct that this applies to is
data_version. Because the data version field by default is zero,
we use that as condition to decide whether to pass the data_version
down to attr_x.
Previously, the code would always pass a data_version=0 down to attr_x,
triggering one of the validity checks, making it return -EINVAL. We
add a simple test case to test for this issue.

We should rely on sparse from epel to do automated sparse checking and
not a git tag. But the 0.6.4 build currently fails on sparse/gcc
redefines.
This magic Awk from Zach script processes sparse and gcc internal defines
and leaves the one intact that sparse doesn't have.

These new shrinkers were recently added. Because there's very little
ways to debug them, or even see them properly function, we should at
least add counters for them.

This is done by xfstests and it's so much easier to follow what is going
on from logs or e.g. serial console that I thought I should do this for
scoutfs tests as well. It makes it so much easier to discern which test
may have been cause for issues when running a bunch of tests and you're
looking back at logs later.

These are extremely limited and very quick basic ACL tests we can
trivially do in under a second - purely basic funtionality tests only.
Signed-off-by: Auke Kok <auke.kok@versity.com>
In 29160b0b I mistakenly disabled all caching of ACLs for el8
instead of only disabling cache lookups. The correct change
should have been to disable cache lookups only, and leave setting the
acl cache after storing or fetching, as the kernel needs this data
to resolve acls when doing permission checks.
Restore the acl cache insertions fixes.

The test harness provides a TMP directory for tests to use. It's badly
named. It's meant to be more of a scratch directory that is not on the
FS being tested.
Tests use it both for small log files that give insight into the
platform and for large generated files that are not worth saving. We
want to save the directory after test runs to get at the log files, but
we don't want to burn a ton of space also saving large generated files
This updates the handful of tests to remove their handful of files that
are large enough to be a problem. With these out of the way we can save
the tmp/ directory without its space consumption getting out of hand.

We can rely on `bc` and `date` to record, manipulate and compare
time data with nanosecond precision. This fixes timing issues on
faster systems where this test completes a single pass of createmany in
under 1.0 second, causing the math to always fail.

Change the read_xattr_totls ioctl to use the weak item cache instead of
manually reading and merging the fs items for the xattr totals on every
call.
Signed-off-by: Zach Brown <zab@versity.com>
The _READ_XATTR_TOTALS ioctl had manual code for merging the .totl.
total and value while reading fs items. We're going to want to do this
in another reader so let's put these in their own funcions that clearly
isolate the logic of merging the fs items into a coherent result.
We can get rid of some of the totl_read_ counters that tracked which
items we were merging. They weren't adding much value and conflated the
reading ioctl interface with the merging logic.

Add a bit to the private scoutfs inode flags which indicates that the
inode is in retention mode. The bit is visible through the _attr_x
interface. It can only be set on regular files and when set it prevents
modification to all but non-user xattrs. It can be cleared by root.

We have some fs functions which return info based on the test mount nr
as the test has setup. This refactors those a bit to also provide
some of the info when the caller has a path in a given mount. This will

Now that we have the attr_x calls we can implement stat_more with
get_attr_x and setattr_more with set_attr_x.
The conversion of stat_more fixes a surprising consistency bug.
stat_more wasn't acquiring a cluster lock for the inode nore refreshing
it so it could have returned stale data if modifications were made in
another mount.
