xfs: support lowmode allocations in xfs_bmap_exact_minlen_extent_alloc

xfs: support lowmode allocations in xfs_bmap_exact_minlen_extent_alloc

commit 6aac77059881e4419df499392c995bf02fb9630b upstream.

Currently the debug-only xfs_bmap_exact_minlen_extent_alloc allocation
variant fails to drop into the lowmode last resort allocator, and
thus can sometimes fail allocations for which the caller has a
transaction block reservation.

Fix this by using xfs_bmap_btalloc_low_space to do the actual allocation.

xfs: don't ifdef around the exact minlen allocations

commit b611fddc0435738e64453bbf1dadd4b12a801858 upstream.

Exact minlen allocations only exist as an error injection tool for debug
builds. Currently this is implemented using ifdefs, which means the code
isn't even compiled for non-XFS_DEBUG builds. Enhance the compile test
coverage by always building the code and use the compilers' dead code
elimination to remove it from the generated binary instead.

The only downside is that the alloc_minlen_only field is unconditionally
added to struct xfs_alloc_args now, but by moving it around and packing
it tightly this doesn't actually increase the size of the structure.

xfs: restrict when we try to align cow fork delalloc to cowextsz hints

commit 288e1f693f04e66be99f27e7cbe4a45936a66745 upstream.

xfs/205 produces the following failure when always_cow is enabled:

This is the result of overly aggressive attempts to align cow fork
delalloc reservations to the CoW extent size hint. Looking at the trace
data, we're trying to append a single fsblock to the "fred" file.
Trying to create a speculative post-eof reservation fails because
there's not enough space.

We then set @prealloc_blocks to zero and try again, but the cowextsz
alignment code triggers, which expands our request for a 1-fsblock
reservation into a 39-block reservation. There's not enough space for
that, so the whole write fails with ENOSPC even though there's
sufficient space in the filesystem to allocate the single block that we
need to land the write.

There are two things wrong here -- first, we shouldn't be attempting
speculative preallocations beyond what was requested when we're low on
space. Second, if we've already computed a posteof preallocation, we
shouldn't bother trying to align that to the cowextsize hint.

Fix both of these problems by adding a flag that only enables the
expansion of the delalloc reservation to the cowextsize if we're doing a
non-extending write, and only if we're not doing an ENOSPC retry. This
requires us to move the ENOSPC retry logic to xfs_bmapi_reserve_delalloc.

I probably should have caught this six years ago when 6ca30729c206d was
being reviewed, but oh well. Update the comments to reflect what the
code does now.

Since xfs_bmapi_convert_delalloc() only attempts to allocate the entire

offset. So xfs_convert_blocks() add a loop to do this job and we call it
in the write back path, but xfs_convert_blocks() isn't a common helper.
Let's do it in xfs_bmapi_convert_delalloc() and drop
xfs_convert_blocks(), preparing for the post EOF delalloc blocks

xfs: fix xfs_bmap_add_extent_delay_real for partial conversions

commit d69bee6a35d3c5e4873b9e164dd1a9711351a97c upstream.

[backport: resolve conflict due to xfs_mod_freecounter refactor]

xfs_bmap_add_extent_delay_real takes parts or all of a delalloc extent
and converts them to a real extent. It is written to deal with any
potential overlap of the to be converted range with the delalloc extent,
but it turns out that currently only converting the entire extents, or a
part starting at the beginning is actually exercised, as the only caller
always tries to convert the entire delalloc extent, and either succeeds
or at least progresses partially from the start.

If it only converts a tiny part of a delalloc extent, the indirect block
calculation for the new delalloc extent (da_new) might be equivalent to that
of the existing delalloc extent (da_old). If this extent conversion now
requires allocating an indirect block that gets accounted into da_new,
leading to the assert that da_new must be smaller or equal to da_new
unless we split the extent to trigger.

Except for the assert that case is actually handled by just trying to
allocate more space, as that already handled for the split case (which
currently can't be reached at all), so just reusing it should be fine.
Except that without dipping into the reserved block pool that would make
it a bit too easy to trigger a fs shutdown due to ENOSPC. So in addition
to adjusting the assert, also dip into the reserved block pool.

Note that I could only reproduce the assert with a change to only convert
the actually asked range instead of the full delalloc extent from
xfs_bmapi_write.

xfs: fix error returns from xfs_bmapi_write

commit 6773da870ab89123d1b513da63ed59e32a29cb77 upstream.

[backport: resolve conflicts due to missing quota_repair.c,
rtbitmap_repair.c, xfs_bmap_mark_sick()]

xfs_bmapi_write can return 0 without actually returning a mapping in
mval in two different cases:

1) when there is absolutely no space available to do an allocation
2) when converting delalloc space, and the allocation is so small
that it only covers parts of the delalloc extent before the
range requested by the caller

Callers at best can handle one of these cases, but in many cases can't
cope with either one. Switch xfs_bmapi_write to always return a
mapping or return an error code instead. For case 1) above ENOSPC is
the obvious choice which is very much what the callers expect anyway.
For case 2) there is no really good error code, so pick a funky one
from the SysV streams portfolio.

This fixes the reproducer here:

https://lore.kernel.org/linux-xfs/CAEJPjCvT3Uag-pMTYuigEjWZHn1sGMZ0GCjVVCv29tNHK76Cgg@mail.gmail.com0/

which uses reserved blocks to create file systems that are gravely
out of space and thus cause at least xfs_file_alloc_space to hang
and trigger the lack of ENOSPC handling in xfs_dquot_disk_alloc.

Note that this patch does not actually make any caller but
xfs_alloc_file_space deal intelligently with case 2) above.
