If the network device is being opened right after it has been registered
via function register_netdev(), the device state is not yet consistent in
the context of function ndo_open(). This patch cares about having the

The wilc_wlan_cleanup() function iterates over the list of transmission

list to free all of them as well.
But on the receive loop a pointer to struct txq_entry_t is dereferenced
instead of the pointer to a struct rxq_entry_t. This not only causes a
dereference to a pointer already freed but also leaks the memory in the
struct rxq_entry_t buffer.
Also, the buffer is allocated when MEMORY_STATIC is not defined no when
MEMORY_DYNAMIC is defined. So use #ifndef MEMORY_STATIC instead as it's
done in the rest of the driver to avoid leaking the buffer memory.

This patch fixes a v4.2+ regression introduced by commit c04a6091
that removed support for obsolete sync-and-steering markers usage
as originally defined in RFC-3720.
The regression would involve attempting to send OFMarker=No +
IFMarker=No keys during opertional negotiation login phase,
including when initiators did not actually propose these keys.
The result for MSFT iSCSI initiators would be random junk in
TCP stream after the last successful login request was been sent
signaling the move to full feature phase (FFP) operation.
To address this bug, go ahead and avoid negotiating these keys
by default unless the initiator explicitly proposes them, but
still respond to them with 'No' if they are proposed.
This patch allows target_sense_desc_format() to be called without a
valid se_device pointer, which can occur during an early exception
ahead of transport_lookup_cmd_lun() setting up se_cmd->se_device.

Update __core_scsi3_add_registration() to drop ->pr_kref reference

__core_scsi3_add_registration() expects to drop the reference.
Finally, since there are cases when se_dev_entry->se_lun_acl can

Phy, mdiobus, and netdev struct device fixes
The third version of this series fixes the build error which David
identified, and drops the broken changes for the Cavium Thunger BGX
ethernet driver as this driver requires some complex changes to
resolve the leakage - and this is best done by people who can test
the driver.
Compared to v2, the only patch which has changed is patch 6
"net: fix phy refcounting in a bunch of drivers"
I _think_ I've been able to build-test all the drivers touched by
that patch to some degree now, though several of them needed the
Kconfig hacked to allow it (not all had || COMPILE_TEST clause on
their dependencies.)
Previous cover letters below:
This is the second version of the series, with the comments David had
on the first patch fixed up. Original series description with updated
diffstat below.
While looking at the DSA code, I noticed we have a
of_find_net_device_by_node(), and it looks like users of that are
similarly buggy - it looks like net/dsa/dsa.c is the only user. Fix
that too.
Hi,
While looking at the phy code, I identified a number of weaknesses
where refcounting on device structures was being leaked, where
modules could be removed while in-use, and where the fixed-phy could
end up having unintended consequences caused by incorrect calls to
fixed_phy_update_state().
This patch series resolves those issues, some of which were discovered
with testing on an Armada 388 board. Not all patches are fully tested,
particularly the one which touches several network drivers.
When resolving the struct device refcounting problems, several different
solutions were considered before settling on the implementation here -
one of the considerations was to avoid touching many network drivers.
The solution here is:
phy_attach*() - takes a refcount
phy_detach*() - drops the phy_attach refcount
Provided drivers always attach and detach their phys, which they should
already be doing, this should change nothing, even if they leak a refcount.
of_phy_find_device() and of_* functions which use that take
a refcount. Arrange for this refcount to be dropped once
the phy is attached.
This is the reason why the previous change is important - we can't drop
this refcount taken by of_phy_find_device() until something else holds
a reference on the device. This resolves the leaked refcount caused by
using of_phy_connect() or of_phy_attach().
Even without the above changes, these drivers are leaking by calling
of_phy_find_device(). These drivers are addressed by adding the
appropriate release of that refcount.
The mdiobus code also suffered from the same kind of leak, but thankfully
this only happened in one place - the mdio-mux code.
I also found that the try_module_get() in the phy layer code was utterly
useless: phydev->dev.driver was guaranteed to always be NULL, so
try_module_get() was always being called with a NULL argument. I proved
this with my SFP code, which declares its own MDIO bus - the module use
count was never incremented irrespective of how I set the MDIO bus up.
This allowed the MDIO bus code to be removed from the kernel while there
were still PHYs attached to it.
One other bug was discovered: while using in-band-status with mvneta, it
was found that if a real phy is attached with in-band-status enabled,
and another ethernet interface is using the fixed-phy infrastructure, the
interface using the fixed-phy infrastructure is configured according to
the other interface using the in-band-status - which is caused by the
fixed-phy code not verifying that the phy_device passed in is actually
a fixed-phy device, rather than a real MDIO phy.
Lastly, having mdio_bus reversing phy_device_register() internals seems
like a layering violation - it's trivial to move that code to the phy
device layer.
