[ Upstream commit 44712965bf12ae1758cec4de53816ed4b914ca1a ]
Smatch says:
drivers/net/ethernet/freescale/fec_main.c:3994 fec_drv_remove() error: Using fep after free_{netdev,candev}(ndev);
drivers/net/ethernet/freescale/fec_main.c:3995 fec_drv_remove() error: Using fep after free_{netdev,candev}(ndev);
Since fep pointer is netdev private data, accessing it after free_netdev()
call can cause use-after-free bug. Fix it by moving free_netdev() call at
the end of the function

[ Upstream commit 6a4d7234ae9a3bb31181f348ade9bbdb55aeb5c5 ]
When accessing the timecounter register on an i.MX8MQ the kernel hangs.
This is only the case when the interface is down. This can be reproduced
by reading with 'phc_ctrl eth0 get'.
Like described in the change in 91c0d987a9788dcc5fe26baafd73bf9242b68900
the igp clock is disabled when the interface is down and leads to a
system hang.
So we check if the ptp clock status before reading the timecounter
register.

[ Upstream commit 887078de2a23689e29d6fa1b75d7cbc544c280be ]
Table 8-53 in the QUICC Engine Reference manual shows definitions of
fields up to a size of 192 bytes, not just 128. But in table 8-111,
one does find the text
Base Address of the Global Transmitter Parameter RAM Page. [...]
The user needs to allocate 128 bytes for this page. The address must
be aligned to the page size.
I've checked both rev. 7 (11/2015) and rev. 9 (05/2018) of the manual;
they both have this inconsistency (and the table numbers are the
same).
Adding a bit of debug printing, on my board the struct
ucc_geth_tx_global_pram is allocated at offset 0x880, while
the (opaque) ucc_geth_thread_data_tx gets allocated immediately
afterwards, at 0x900. So whatever the engine writes into the thread
data overlaps with the tail of the global tx pram (and devmem says
that something does get written during a simple ping).
I haven't observed any failure that could be attributed to this, but
it seems to be the kind of thing that would be extremely hard to
debug. So extend the struct definition so that we do allocate 192
bytes.

[ Upstream commit 1385ae5c30f238f81bc6528d897c6d7a0816783f ]
All the buffers and registers are already set up appropriately for an
MTU slightly above 1500, so we just need to expose this to the
networking stack. AFAICT, there's no need to implement .ndo_change_mtu
when the receive buffers are always set up to support the max_mtu.
This fixes several warnings during boot on our mpc8309-board with an
embedded mv88e6250 switch:
mv88e6085 mdio@e0102120:10: nonfatal error -34 setting MTU 1500 on port 0
...
mv88e6085 mdio@e0102120:10: nonfatal error -34 setting MTU 1500 on port 4
ucc_geth e0102000.ethernet eth1: error -22 setting MTU to 1504 to include DSA overhead
The last line explains what the DSA stack tries to do: achieving an MTU
of 1500 on-the-wire requires that the master netdevice connected to
the CPU port supports an MTU of 1500+the tagging overhead.

[ Upstream commit d6a076d68c6b5d6a5800f3990a513facb7016dea ]
When PTP timestamping is enabled on Tx, the controller
inserts the Tx timestamp at the beginning of the frame
buffer, between SFD and the L2 frame header. This means
that the skb provided by the stack is required to have
enough headroom otherwise a new skb needs to be created
by the driver to accommodate the timestamp inserted by h/w.
Up until now the driver was relying on the second option,
using skb_realloc_headroom() to create a new skb to accommodate
PTP frames. Turns out that this method is not reliable, as
reallocation of skbs for PTP frames along with the required
overhead (skb_set_owner_w, consume_skb) is causing random
crashes in subsequent skb_*() calls, when multiple concurrent
TCP streams are run at the same time on the same device
(as seen in James' report).
Note that these crashes don't occur with a single TCP stream,
nor with multiple concurrent UDP streams, but only when multiple
TCP streams are run concurrently with the PTP packet flow
(doing skb reallocation).
This patch enforces the first method, by requesting enough
headroom from the stack to accommodate PTP frames, and so avoiding
skb_realloc_headroom() & co, and the crashes no longer occur.
There's no reason not to set needed_headroom to a large enough
value to accommodate PTP frames, so in this regard this patch
is a fix.

skb_realloc_headroom() for PTP frames can cause random crashes,
mostly in subsequent skb_*() calls, when multiple concurrent
TCP streams are run at the same time with the PTP flow
on the same device (as seen in James' report). I also noticed
that when the system is loaded by sending multiple TCP streams,
the driver receives cloned skbs in large numbers.
skb_cow_head() instead proves to be stable in this scenario,
and not only handles cloned skbs too but it's also more efficient
and widely used in other drivers.
The commit introducing skb_realloc_headroom in the driver
goes back to 2009, commit 93c1285c5d92
("gianfar: reallocate skb when headroom is not enough for fcb").
For practical purposes I'm referencing a newer commit (from 2012)
that brings the code to its current structure (and fixes the PTP
case).

reference count of the previous node, however when control
is transferred from the middle of the loop, as in the case of

Fix a potential memory leak in gianfar.c by inserting of_node_put()
before the goto statement.

[ Upstream commit 79dde73cf9bcf1dd317a2667f78b758e9fe139ed ]
ugeth_quiesce/activate are used to halt the controller when there is a
link change that requires to reconfigure the mac.
The previous implementation called netif_device_detach(). This however
causes the initial activation of the netdevice to fail precisely because
it's detached. For details, see [1].
A possible workaround was the revert of commit
net: linkwatch: add check for netdevice being present to linkwatch_do_dev
However, the check introduced in the above commit is correct and shall be
kept.
The netif_device_detach() is thus replaced with
netif_tx_stop_all_queues() that prevents any tranmission. This allows to
perform mac config change required by the link change, without detaching
the corresponding netdevice and thus not preventing its initial
activation.

It seems the same thing can happen with dpaa and ucc_geth, so change
all three to do an explicit 'select FIXED_PHY'.
The fixed-phy driver actually has an alternative stub function that
theoretically allows building network drivers when fixed-phy is
disabled, but I don't see how that would help here, as the drivers
presumably would not work then.

[ Upstream commit c26a2c2ddc0115eb088873f5c309cf46b982f522 ]
The driver wrongly assumes that it is the only entity that can set the
SKBTX_IN_PROGRESS bit of the current skb. Therefore, in the
gfar_clean_tx_ring function, where the TX timestamp is collected if
necessary, the aforementioned bit is used to discriminate whether or not
the TX timestamp should be delivered to the socket's error queue.
But a stacked driver such as a DSA switch can also set the
SKBTX_IN_PROGRESS bit, which is actually exactly what it should do in
order to denote that the hardware timestamping process is undergoing.
Therefore, gianfar would misinterpret the "in progress" bit as being its
own, and deliver a second skb clone in the socket's error queue,
completely throwing off a PTP process which is not expecting to receive
it, _even though_ TX timestamping is not enabled for gianfar.
There have been discussions [0] as to whether non-MAC drivers need or
not to set SKBTX_IN_PROGRESS at all (whose purpose is to avoid sending 2
timestamps, a sw and a hw one, to applications which only expect one).
But as of this patch, there are at least 2 PTP drivers that would break
in conjunction with gianfar: the sja1105 DSA switch and the felix
switch, by way of its ocelot core driver.
So regardless of that conclusion, fix the gianfar driver to not do stuff
based on flags set by others and not intended for it.

commit a31eda65ba210741b598044d045480494d0ed52a upstream.
pm_runtime_put_autosuspend in probe will call runtime suspend to
disable clks automatically if CONFIG_PM is defined. (If CONFIG_PM
is not defined, its implementation will be empty, then runtime
suspend will not be called.)
Therefore, we can call pm_runtime_get_sync to runtime resume it
first to enable clks, which matches the runtime suspend. (Only when
CONFIG_PM is defined, otherwise pm_runtime_get_sync will also be
empty, then runtime resume will not be called.)
Then it is fine to disable clks without causing clock count mis-match.

[ Upstream commit ce8d24f9a5965a58c588f9342689702a1024433c ]
Fix the clk mismatch in the error path "failed_reset" because
below error path will disable clk_ahb and clk_ipg directly, it
should use pm_runtime_put_noidle() instead of pm_runtime_put()
to avoid to call runtime resume callback.

After getting a reference to the platform device's of_node the probe
function ends up calling of_find_matching_node() using the node as an
argument. The function takes care of decreasing the refcount on it. We
are then incorrectly decreasing the refcount on that node again.
This patch removes the unwarranted call to of_node_put().

Commit db65f35f50e0 ("net: fec: add support of ethtool get_regs") introduce
ethool "--register-dump" interface to dump all FEC registers.
But not all silicon implementations of the Freescale FEC hardware module
have the FRBR (FIFO Receive Bound Register) and FRSR (FIFO Receive Start
Register) register, so we should not be trying to dump them on those that
don't.
To fix it we create a quirk flag, FEC_QUIRK_HAS_RFREG, and check it before
dump those RX FIFO registers.

During certain heavy network loads TX could time out
with TX ring dump.
TX is sometimes never restarted after reaching
"tx_stop_threshold" because function "fec_enet_tx_queue"
only tests the first queue.
In addition the TX timeout callback function failed to
recover because it also operated only on the first queue.

[ Upstream commit 590399ddf9561f2ed0839311c8ae1be21597ba68 ]
Don't include in the Rx bytecount of the packet sent up the stack:
the FCB (frame control block), and the padding bytes inserted by
the controller into the frame payload, nor the FCS. All these are
being pulled out of the skb by gfar_process_frame().
This issue is old, likely from the driver's beginnings, however
it was amplified by recent:
commit d903ec77118c ("gianfar: simplify FCS handling and fix memory leak")
which basically added the FCS to the Rx bytecount, and so brought
this to my attention.

[ Upstream commit 202a0a70e445caee1d0ec7aae814e64b1189fa4d ]
When the frame check sequence (FCS) is split across the last two frames
of a fragmented packet, part of the FCS gets counted twice, once when
subtracting the FCS, and again when subtracting the previously received
data.
For example, if 1602 bytes are received, and the first fragment contains
the first 1600 bytes (including the first two bytes of the FCS), and the
second fragment contains the last two bytes of the FCS:
'skb->len == 1600' from the first fragment
size = lstatus & BD_LENGTH_MASK; # 1602
size -= ETH_FCS_LEN; # 1598
size -= skb->len; # -2
Since the size is unsigned, it wraps around and causes a BUG later in
the packet handling, as shown below:
kernel BUG at ./include/linux/skbuff.h:2068!
Oops: Exception in kernel mode, sig: 5 [#1]

Change the size to a signed integer and then trim off any part of the
FCS that was received prior to the last fragment.
