libceph: init the cursor when preparing sparse read in msgr2

[ Upstream commit 321e3c3de53c7530cd518219d01f04e7e32a9d23 ]

The cursor is no longer initialized in the OSD client, causing the
sparse read state machine to fall into an infinite loop. The cursor
should be initialized in IN_S_PREPARE_SPARSE_DATA state.

libceph: just wait for more data to be available on the socket

[ Upstream commit 8e46a2d068c92a905d01cbb018b00d66991585ab ]

A short read may occur while reading the message footer from the
socket. Later, when the socket is ready for another read, the
messenger invokes all read_partial_*() handlers, including
read_partial_sparse_msg_data(). The expectation is that
read_partial_sparse_msg_data() would bail, allowing the messenger to
invoke read_partial() for the footer and pick up where it left off.

However read_partial_sparse_msg_data() violates that and ends up
calling into the state machine in the OSD client. The sparse-read
state machine assumes that it's a new op and interprets some piece of
the footer as the sparse-read header and returns bogus extents/data
length, etc.

To determine whether read_partial_sparse_msg_data() should bail, let's
reuse cursor->total_resid. Because once it reaches to zero that means
all the extents and data have been successfully received in last read,
else it could break out when partially reading any of the extents and
data. And then osd_sparse_read() could continue where it left off.

libceph: support sparse reads on msgr2 secure codepath

Add a new init_sgs_pages helper that populates the scatterlist from
an arbitrary point in an array of pages.

Change setup_message_sgs to take an optional pointer to an array of
pages. If that's set, then the scatterlist will be set using that
array instead of the cursor.

When given a sparse read on a secure connection, decrypt the data
in-place rather than into the final destination, by passing it the
in_enc_pages array.

After decrypting, run the sparse_read state machine in a loop, copying
data from the decrypted pages until it's complete.

libceph: new sparse_read op, support sparse reads on msgr2 crc codepath

Add support for a new sparse_read ceph_connection operation. The idea is
that the client driver can define this operation use it to do special
handling for incoming reads.

The alloc_msg routine will look at the request and determine whether the
reply is expected to be sparse. If it is, then we'll dispatch to a
different set of state machine states that will repeatedly call the
driver's sparse_read op to get length and placement info for reading the
extent map, and the extents themselves.

This necessitates adding some new field to some other structs:

- The msg gets a new bool to track whether it's a sparse_read request.

- A new field is added to the cursor to track the amount remaining in the
current extent. This is used to cap the read from the socket into the
msg_data

- Handing a revoke with all of this is particularly difficult, so I've
added a new data_len_remain field to the v2 connection info, and then
use that to skip that much on a revoke. We may want to expand the use of
that to the normal read path as well, just for consistency's sake.

ASoC: Improve coverage in default KUnit runs

Merge series from Mark Brown <broonie@kernel.org>:

We have some KUnit tests for ASoC but they're not being run as much as
they should be since ASoC isn't enabled in the configs used by default
with KUnit and in the case of the topology tests there is no way to
enable them without enabling drivers that use them. This series
provides a Kconfig option which KUnit can use directly rather than worry
about drivers.

Further, since KUnit is typically run in UML but ALSA prevents build
with UML we need to remove that Kconfig conflict. As far as I can tell
the motiviation for this is that many ALSA drivers use iomem APIs which
are not available under UML and it's more trouble than it's worth to go
through and add per driver dependencies. In order to avoid these issues
we also provide stubs for these APIs so there are no build time issues
if a driver relies on iomem but does not depend on it. With these stubs
I am able to build all the sound drivers available in a UML defconfig
(UML allmodconfig appears to have substantial other issues in a quick
test).

With this series I am able to run the topology KUnit tests as part of a
kunit --alltests run.

libceph: harden msgr2.1 frame segment length checks

ceph_frame_desc::fd_lens is an int array. decode_preamble() thus
effectively casts u32 -> int but the checks for segment lengths are
written as if on unsigned values. While reading in HELLO or one of the
AUTH frames (before authentication is completed), arithmetic in
head_onwire_len() can get duped by negative ctrl_len and produce
head_len which is less than CEPH_PREAMBLE_LEN but still positive.
This would lead to a buffer overrun in prepare_read_control() as the
preamble gets copied to the newly allocated buffer of size head_len.
