be2net: patch set

This patch set contains 2 driver fixes to a Lancer HW issue and a fix
to a double free bug. Pls apply to the "net" tree. Thanks!

Patch 1 now enables filters only after creating RXQs. This is done as
HW issues were observed on Lancer adapters if filters
(flags, mac addrs etc) are enabled *before* creating RXQs. This patch
changes the driver design by enabling filters in be_open() --
instead of be_setup() -- after RXQs are created and buffers posted.

Patch 2 fixes an RX stall issue that was seen on Lancer adapters when
RXQs are destroyed while they are in an "out of buffer" state.
This patch fixes this issue by posting 64 buffers to each RXQ before
destroying them in the close path. This is done after ensuring that no
more new packets are selected for transfer to the RXQs by disabling
interface filters.

Patch 3 protects eqo->affinity_mask variable from being freed twice and
resulting in a crash.  It's now freed only when EQs haven't yet been
destroyed.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

There are paths in the driver such as an unrecoverable error (UE) detection
followed by a driver unload wherein be_clear() is invoked twice.
Individual data structures are reset so that they are not cleaned/freed
twice. This patch does the same for eqo->affinity_mask. It is freed only
if EQs haven't yet been destroyed. This fixes a possible crash when
affinity_mask is freed twice.

Two new wrapper functions, be_enable_if_filters() and
be_disable_if_filters() are introduced to enable/disable IFACE filters in
be_open()/be_close() respectively. In be_setup() the IFACE is now created
only with the RSS flag.

virtio declares support for NETIF_F_FRAGLIST, but assumes
that there are at most MAX_SKB_FRAGS + 2 fragments which isn't
always true with a fraglist.

A longer fraglist in the skb will make the call to skb_to_sgvec overflow
the sg array, leading to memory corruption.

Drop NETIF_F_FRAGLIST so we only get what we can handle.

following static checker warning:

The NSS_COMMON_CLK_SRC_CTRL_OFFSET macro is used once as an offset, and

required.

Prior to this patch, rx buffer size for each rx queue
of an interface is configurable through dts bindings.
But for an interface, the first rx queue's rx buffer
size is always the usual MTU size (plus usual overhead)
and page size for the remaining rx queues (if they are
enabled by specifying a non-zero rx queue depth dts
binding of the corresponding interface).  This patch
removes the rx buffer size configuration capability.

This patch fixes it by making skb_set_peeked return the new skb

The clocks are initially active and thus the device is marked active.
This still keeps the PM refcount at 0, the pm_runtime_put_autosuspend()
call at the end of probe then leaves us with an invalid refcount of -1,
which in turn leads to the device staying in suspended state even though
netdev open had been called.

Fix this by initializing the refcount to be coherent with the initial
device status.

Without this initialization, gateways which actually announce up/down
bandwidth of 0/0 could be added. If these nodes get purged via
_batadv_purge_orig() later, the gw_node structure does not get removed
since batadv_gw_node_delete() updates the gw_node with up/down
bandwidth of 0/0, and the updating function then discards the change
and does not free gw_node.

This results in leaking the gw_node structures, which references other
structures: gw_node -> orig_node -> orig_node_ifinfo -> hardif. When
removing the interface later, the open reference on the hardif may cause
hangs with the infamous "unregister_netdevice: waiting for mesh1 to
become free. Usage count = 1" message.

The tt_local_entry deletion performed in batadv_tt_local_remove() was neither
protecting against simultaneous deletes nor checking whether the element was
still part of the list before calling hlist_del_rcu().

Replacing the hlist_del_rcu() call with batadv_hash_remove() provides adequate
protection via hash spinlocks as well as an is-element-still-in-hash check to
avoid 'blind' hash removal.

When a node running DAT receives an ARP request from the LAN for the
first time, it is likely that this node will request the ARP entry
through the distributed ARP table (DAT) in the mesh.

Once a DAT reply is received the asking node must check if the MAC
address for which the IP address has been asked is local. If it is, the
node must drop the ARP reply bceause the client should have replied on
its own locally.

Forwarding this reply means fooling any L2 bridge (e.g. Ethernet
switches) lying between the batman-adv node and the LAN. This happens
because the L2 bridge will think that the client sending the ARP reply
lies somewhere in the mesh, while this node is sitting in the same LAN.

"len" is a signed integer.  We check that len is not negative, so it
goes from zero to INT_MAX.  PAGE_SIZE is unsigned long so the comparison
is type promoted to unsigned long.  ULONG_MAX - 4095 is a higher than
INT_MAX so the condition can never be true.

====================
gianfar: wol magic packet fixes

These changes were already validated as part of FSL SDK.
Patch 2 fixes occasional wake-on magic packet failures during
traffic, probably due to incorrect traffic stop/ device halt
sequence and incorrect usage of txlock.
====================

The wol_en flag is 0 by default anyway, and we have the
following inconsistency: a MAGIC packet wol capable eth
interface is registered as a wake-up source but unable
to wake-up the system as wol_en is 0 (wake-on flag set to 'd').
Calling set_wakeup_enable() at netdev open is just redundant
because wol_en is 0 by default.
Let only ethtool call set_wakeup_enable() for now.

The bflock is obviously obsoleted, its utility has been corroded
over time.  The bitfield flags used today in gianfar are accessed
only on the init/ config path, with no real possibility of
concurrency - nothing that would justify smth. like bflock.

If we disable NAPI in the first place we can mask the device's
interrupts (and halt it) without fearing that imask may be
concurrently accessed from interrupt context, so there's
no need to do local_irq_save() around gfar_halt_nodisable().
lock_rx_qs()/unlock_tx_qs() are just obsoleted and potentially
buggy routines.  The txlock is currently used in the driver only
to manage TX congestion, it has nothing to do with halting the
device.  With these changes, the TX processing is stopped before
gfar_halt().

Compact gfar_halt() is used instead of gfar_halt_nodisable(),
as it disables Rx/TX DMA h/w blocks and the Rx/TX h/w queues.
gfar_start() re-enables all these blocks on resume.  Enabling
the magic-packet mode remains the same, note that the RX block
is re-enabled just before entering sleep mode.

Add IRQF_NO_SUSPEND flag for the error interrupt line, to signal
that the interrupt line must remain active during sleep in order
to wake the system by magic packet (MAG) reception interrupt.
(On some systems the MAG interrupt did trigger w/o this flag
as well, but on others it didn't.)

Without these fixes, when suspended during fair Tx traffic the
interface occasionally failed to be woken up by magic packet.

When we share an action within a filter, the bind refcnt
should increase, therefore we should not call tcf_hash_release().
