====================
net: add a regmap-based mdio driver and drop TSE PCS
This is the V4 of a series that follows-up on the work [1] aiming to drop the
altera TSE PCS driver, as it turns out to be a version of the Lynx PCS exposed
as a memory-mapped block, instead of living on an MDIO bus.
One step of this removal involved creating a regmap-based mdio driver
that translates MDIO accesses into the actual underlying bus that
exposes the register. The register layout must of course match the
standard MDIO layout, but we can now account for differences in stride
with recent work on the regmap subsystem [2].
Sorry for repeating this, but I didn't hear anything on this matter in previous
iterations, Mark, Net maintainers, this series depends on the patch e12ff2876493 that was recently merged into the regmap tree [3].
For this series to be usable in net-next, this patch must be applied
beforehand. Should Mark create a tag that would then be merged into
net-next ? Or should we just wait for the next release to merge this
into net-next ?
This series introduces a new MDIO driver, and uses it to convert Altera
TSE from the actual TSE PCS driver to Lynx PCS.
Since it turns out dwmac_socfpga also uses a TSE PCS block, port that
driver to Lynx as well.
Changes in V4 :
- Use new pcs_lynx_create/destroy helpers added by Russell
- Rework the cleanup sequence to avoid leaking data
- Rework a bit KConfig to properly select dependencies
- Fix a few hiccups with misplaced hunks in 2 commits
Changes in V3 :
- Use a dedicated struct for the mii bus's priv data, to avoid
duplicating the whole struct mdio_regmap_config, from which 2 fields
only are necessary after init, as suggested by Russell
- Use ~0 instead of ~0UL for the no-scan bitmask, following Simon's
review.
Changes in V2 :
- Use phy_mask to avoid unnecessarily scanning the whole mdio bus
- Go one step further and completely disable scanning if users
set the .autoscan flag to false, in case the mdiodevice isn't an
actual PHY (a PCS for example).

There exists several examples today of devices that embed an ethernet

MDIO.
As phylib and phylink are designed to use mdiodevices, this driver
allows creating a virtual MDIO bus, that translates mdiodev register
accesses to regmap accesses.
The reason we use regmap is because there are at least 3 such devices
known today, 2 of them are Altera TSE PCS's, memory-mapped, exposed
with a 4-byte stride in stmmac's dwmac-socfpga variant, and a 2-byte
stride in altera-tse. The other one (nxp,sja1110-base-tx-mdio) is

It looks like this message is not that helpful after all: maybe it can
be used as a sign to know if there is something wrong, e.g. if a device

better ways to monitor and diagnose such issues.
When looking at commit 3c21edbd1137 ("[IPV6]: Defer IPv6 device
initialization until the link becomes ready.") which introduces this new
message, it seems it had been added to verify that the new feature was
working as expected. It could have then used a lower level than "info"

It seems then OK today to simply lower its level, similar to commit 7c62b8dd5ca8 ("net/ipv6: lower the level of "link is not ready" messages")

net: phylib: fix phy_read*_poll_timeout()
Dan Carpenter reported a signedness bug in genphy_loopback(). Andrew
reports that:
"It is common to get this wrong in general with PHY drivers. Dan
regularly posts fixes like this soon after a PHY driver patch it
merged. I really wish we could somehow get the compiler to warn when
the result from phy_read() is stored into a unsigned type. It would
save Dan a lot of work."
Let's make phy_read*_poll_timeout() immune to further issues when "val"
is an unsigned type by storing the read function's result in a signed
int as well as "val", and using the signed variable both to check for
an error and for propagating that error to the caller.
The advantage of this method is we don't change where the cast from
the signed return code to the user's variable occurs - so users will
see no change.
Previously Heiner changed phy_read_poll_timeout() to check for an error
before evaluating the user supplied condition, but didn't update
phy_read_mmd_poll_timeout(). Make that change there too.

ipv4: Drop tos parameter from flowi4_update_output()
Callers of flowi4_update_output() never try to update ->flowi4_tos:
* ip_route_connect() updates ->flowi4_tos with its own current

* ip_route_newports() has two users: tcp_v4_connect() and
dccp_v4_connect. Both initialise fl4 with ip_route_connect(), which
in turn sets ->flowi4_tos with RT_TOS(inet_sk(sk)->tos) and
->flowi4_scope based on SOCK_LOCALROUTE.
Then ip_route_newports() updates ->flowi4_tos with
RT_CONN_FLAGS(sk), which is the same as RT_TOS(inet_sk(sk)->tos),
unless SOCK_LOCALROUTE is set on the socket. In that case, the
lowest order bit is set to 1, to eventually inform
ip_route_output_key_hash() to restrict the scope to RT_SCOPE_LINK.
This is equivalent to properly setting ->flowi4_scope as
ip_route_connect() did.
* ip_vs_xmit.c initialises ->flowi4_tos with memset(0), then calls
flowi4_update_output() with tos=0.
* sctp_v4_get_dst() uses the same RT_CONN_FLAGS_TOS() when
initialising ->flowi4_tos and when calling flowi4_update_output().
In the end, ->flowi4_tos never changes. So let's just drop the tos
parameter. This will simplify the conversion of ->flowi4_tos from __u8

fork, vhost: Use CLONE_THREAD to fix freezer/ps regression
When switching from kthreads to vhost_tasks two bugs were added:
1. The vhost worker tasks's now show up as processes so scripts doing
ps or ps a would not incorrectly detect the vhost task as another
process. 2. kthreads disabled freeze by setting PF_NOFREEZE, but
vhost tasks's didn't disable or add support for them.
To fix both bugs, this switches the vhost task to be thread in the
process that does the VHOST_SET_OWNER ioctl, and has vhost_worker call
get_signal to support SIGKILL/SIGSTOP and freeze signals. Note that
SIGKILL/STOP support is required because CLONE_THREAD requires
CLONE_SIGHAND which requires those 2 signals to be supported.
This is a modified version of the patch written by Mike Christie
<michael.christie@oracle.com> which was a modified version of patch
originally written by Linus.
Much of what depended upon PF_IO_WORKER now depends on PF_USER_WORKER.
Including ignoring signals, setting up the register state, and having
get_signal return instead of calling do_group_exit.
Tidied up the vhost_task abstraction so that the definition of
vhost_task only needs to be visible inside of vhost_task.c. Making
it easier to review the code and tell what needs to be done where.
As part of this the main loop has been moved from vhost_worker into
vhost_task_fn. vhost_worker now returns true if work was done.
The main loop has been updated to call get_signal which handles
SIGSTOP, freezing, and collects the message that tells the thread to
exit as part of process exit. This collection clears
__fatal_signal_pending. This collection is not guaranteed to
clear signal_pending() so clear that explicitly so the schedule()
sleeps.
For now the vhost thread continues to exist and run work until the
last file descriptor is closed and the release function is called as
part of freeing struct file. To avoid hangs in the coredump
rendezvous and when killing threads in a multi-threaded exec. The
coredump code and de_thread have been modified to ignore vhost threads.
Remvoing the special case for exec appears to require teaching
vhost_dev_flush how to directly complete transactions in case
the vhost thread is no longer running.
Removing the special case for coredump rendezvous requires either the
above fix needed for exec or moving the coredump rendezvous into
get_signal.

Active subflow are inserted into the connection list at creation time.

mptcp: fix connect timeout handling
Ondrej reported a functional issue WRT timeout handling on connect
with a nice reproducer.
The problem is that the current mptcp connect waits for both the
MPTCP socket level timeout, and the first subflow socket timeout.
The latter is not influenced/touched by the exposed setsockopt().
Overall the above makes the SO_SNDTIMEO a no-op on connect.
Since mptcp_connect is invoked via inet_stream_connect and the
latter properly handle the MPTCP level timeout, we can address the
issue making the nested subflow level connect always unblocking.
This also allow simplifying a bit the code, dropping an ugly hack
to handle the fastopen and custom proto_ops connect.
The issues predates the blamed commit below, but the current resolution
requires the infrastructure introduced there.

When sack compression is triggered in the tcp_compressed_ack_kick(),

sfc: fix error unwinds in TC offload
Failure ladders weren't exactly unwinding what the function had done up
to that point; most seriously, when we encountered an already offloaded
rule, the failure path tried to remove the new rule from the hashtable,
which would in fact remove the already-present 'old' rule (since it has
the same key) from the table, and leak its resources.

net: don't set sw irq coalescing defaults in case of PREEMPT_RT
If PREEMPT_RT is set, then assume that the user focuses on minimum
latency. Therefore don't set sw irq coalescing defaults.
This affects the defaults only, users can override these settings
via sysfs.
net/mlx5: Read embedded cpu after init bit cleared
During driver load it reads embedded_cpu bit from initialization
segment, but the initialization segment is readable only after
initialization bit is cleared.
Move the call to mlx5_read_embedded_cpu() right after initialization bit
cleared.
The crash is due to matrix_alloc_area() attempting to access per-CPU
memory for CPUs that are not present on the system. The CPU mask
passed into reserve_managed_vector() via it's @irqd parameter is
corrupted because it contains uninitialized stack data.

net/mlx5: Fix setting of irq->map.index for static IRQ case
When dynamic IRQ allocation is not supported all IRQs are allocated up
front in mlx5_irq_table_create() instead of dynamically as part of
mlx5_irq_alloc(). In the latter dynamic case irq->map.index is set
via the mapping returned by pci_msix_alloc_irq_at(). In the static case
and prior to commit 1da438c0ae02 ("net/mlx5: Fix indexing of mlx5_irq")
irq->map.index was set in mlx5_irq_alloc() twice once initially to 0 and
then to the requested index before storing in the xarray. After this
commit it is only set to 0 which breaks all other IRQ mappings.
Fix this by setting irq->map.index to the requested index together with
irq->map.virq and improve the related comment to make it clearer which
cases it deals with.

net/mlx5: Remove rmap also in case dynamic MSIX not supported
mlx5 add IRQs to rmap upon MSIX request, and mlx5 remove rmap from
MSIX only if msi_map.index is populated. However, msi_map.index is
populated only when dynamic MSIX is supported. This results in freeing
IRQs without removing them from rmap, which triggers the bellow
WARN_ON[1].
rmap is a feature which have no relation to dynamic MSIX.
Hence, remove the check of msi_map.index when removing IRQ from rmap.
