f49e50f830 mdio-sun4i: Fix a memory leak
[ Upstream commit 56c0290202ab94a2f2780c449395d4ae8495fab4 ]

If the probing of the regulator is deferred, the memory allocated by
'mdiobus_alloc_size()' will be leaking.
It should be freed before the next call to 'sun4i_mdio_probe()' which will
reallocate it.

63b9e4176b xen-netfront: enable device after manual module load
[ Upstream commit b707fda2df4070785d0fa8a278aa13944c5f51f8 ]

When loading the module after unloading it, the network interface would
not be enabled and thus wouldn't have a backend counterpart and unable
to be used by the guest.

The guest would face errors like:

  [root@guest ~]# ethtool -i eth0
  Cannot get driver information: No such device

  [root@guest ~]# ifconfig eth0
  eth0: error fetching interface information: Device not found

This patch initializes the state of the netfront device whenever it is
loaded manually, this state would communicate the netback to create its
device and establish the connection between them.

8e943a8530 bnxt_en: Fix the 'Invalid VF' id check in bnxt_vf_ndo_prep routine.
[ Upstream commit 78f300049335ae81a5cc6b4b232481dc5e1f9d41 ]

In bnxt_vf_ndo_prep (which is called by bnxt_get_vf_config ndo), there is a
check for "Invalid VF id". Currently, the check is done against max_vfs.
However, the user doesn't always create max_vfs. So, the check should be
against the created number of VFs. The number of bnxt_vf_info structures
that are allocated in bnxt_alloc_vf_resources routine is the "number of
requested VFs". So, if an "invalid VF id" falls between the requested
number of VFs and the max_vfs, the driver will be dereferencing an invalid
pointer.

7776af55a7 can: flex_can: Correct the checking for frame length in flexcan_start_xmit()
[ Upstream commit 13454c14550065fcc1705d6bd4ee6d40e057099f ]

The flexcan_start_xmit() function compares the frame length with data
register length to write frame content into data[0] and data[1]
register. Data register length is 4 bytes and frame maximum length is 8
bytes.

Fix the check that compares frame length with 3. Because the register
length is 4.

a4bd8a5a0c bnx2x: Improve reliability in case of nested PCI errors
[ Upstream commit f7084059a9cb9e56a186e1677b1dcffd76c2cd24 ]

While in recovery process of PCI error (called EEH on PowerPC arch),
another PCI transaction could be corrupted causing a situation of
nested PCI errors. Also, this scenario could be reproduced with
error injection mechanisms (for debug purposes).

We observe that in case of nested PCI errors, bnx2x might attempt to
initialize its shmem and cause a kernel crash due to bad addresses
read from MCP. Multiple different stack traces were observed depending
on the point the second PCI error happens.

This patch avoids the crashes by:

 * failing PCI recovery in case of nested errors (since multiple
 PCI errors in a row are not expected to lead to a functional
 adapter anyway), and by,

 * preventing access to adapter FW when MCP is failed (we mark it as
 failed when shmem cannot get initialized properly).

A customer noticed RX path hang when MTU is changed on the fly while

belongs to same ASIC family, we observed same issue and same fix
could solve this problem for 5720.

arc_emac_rx() has some issues found by code review.

In case netdev_alloc_skb_ip_align() or dma_map_single() failure
rx fifo entry will not be returned to EMAC.

In case dma_map_single() failure previously allocated skb became
lost to driver. At the same time address of newly allocated skb
will not be provided to EMAC.

d9a4d80bb3 net: hp100: remove unnecessary #ifdefs
commit 747a11279a442b913a57bf38934879babab3b58b upstream.

Building the hp100 ethernet driver causes warnings when both the PCI
and EISA drivers are disabled:

ethernet/hp/hp100.c: In function 'hp100_module_init':
ethernet/hp/hp100.c:3047:2: warning: label 'out3' defined but not used [-Wunused-label]
ethernet/hp/hp100.c: At top level:
ethernet/hp/hp100.c:2828:13: warning: 'cleanup_dev' defined but not used [-Wunused-function]

We can easily avoid the warnings and make the driver look slightly
nicer by removing the #ifdefs that check for the CONFIG_PCI and
CONFIG_EISA, as all the registration functions are designed to
have no effect when the buses are disabled.

d3843789e7 wireless: cw1200: use __maybe_unused to hide pm functions_
commit 836856e3bd61d0644e5178a2c1b51d90459e2788 upstream.

The cw1200 uses #ifdef to check for CONFIG_PM, but then
uses SIMPLE_DEV_PM_OPS, which leaves the references out when
CONFIG_PM_SLEEP is not defined, so we get a warning with
PM=y && PM_SLEEP=n:

drivers/net/wireless/st/cw1200/cw1200_spi.c:450:12: error: 'cw1200_spi_suspend' defined but not used [-Werror=unused-function]

This removes the incorrect #ifdef and instead uses a __maybe_unused
annotation to let the compiler know it can silently drop
the function definition.

For the DEV_PM_OPS definition, we can use an IS_ENABLED() check
to avoid defining the structure when CONFIG_PM is not set without
the #ifdef.

6420c014ed cw1200: fix bogus maybe-uninitialized warning
commit 7fc1503c906f0fac62d3506a6e993e49fb996248 upstream.

On x86, the cw1200 driver produces a rather silly warning about the
possible use of the 'ret' variable without an initialization
presumably after being confused by the architecture specific definition
of WARN_ON:

drivers/net/wireless/st/cw1200/wsm.c: In function ‘wsm_handle_rx’:
drivers/net/wireless/st/cw1200/wsm.c:1457:9: error: ‘ret’ may be used uninitialized in this function [-Werror=maybe-uninitialized]

We have already checked that 'count' is larger than 0 here, so
we know that 'ret' is initialized. Changing the 'for' loop
into do/while also makes this clear to the compiler.

commit 2acd846485549655582ee379ceb966206f91e6f8 upstream.

The rtl8821ae_dm_txpower_tracking_callback_thermalmeter function
contains a call to RT_TRACE() that is indented in a misleading
way, as pointed out by a gcc-6 warning:

drivers/net/wireless/realtek/rtlwifi/rtl8821ae/dm.c: In function 'rtl8821ae_dm_txpower_tracking_callback_thermalmeter':

It is clear from the context that the call was not meant to be
part of the loop and only the indentation is wrong, so this
removes the extra tabs.

affad7ad16 USB: cdc_subset: only build when one driver is enabled
commit f3bb23764fac042d189129d485d3a9246cb777da upstream.

This avoids a harmless randconfig warning I get when USB_NET_CDC_SUBSET
is enabled, but all of the more specific drivers are not:

drivers/net/usb/cdc_subset.c:241:2: #warning You need to configure some hardware for this driver

The current behavior is clearly intentional, giving a warning when
a user picks a configuration that won't do anything good. The only
reason for even addressing this is that I'm getting close to
eliminating all 'randconfig' warnings on ARM, and this came up
a couple of times.

My workaround is to not even build the module when none of the
configurations are enable.

Alternatively we could simply remove the #warning (nothing wrong
for compile-testing), turn it into a runtime warning, or
change the Kconfig options into a menu to hide CONFIG_USB_NET_CDC_SUBSET.

d9e7836a88 vmxnet3: prevent building with 64K pages
commit fbdf0e28d061708cf18ba0f8e0db5360dc9a15b9 upstream.

I got a warning about broken code on ARM64 with 64K pages:

drivers/net/vmxnet3/vmxnet3_drv.c: In function 'vmxnet3_rq_init':
drivers/net/vmxnet3/vmxnet3_drv.c:1679:29: error: large integer implicitly truncated to unsigned type [-Werror=overflow]
    rq->buf_info[0][i].len = PAGE_SIZE;

'len' here is a 16-bit integer, so this clearly won't work. I don't think
this driver is used much on anything other than x86, so there is no need
to fix this properly and we can work around it with a Kconfig dependency
to forbid known-broken configurations. qemu in theory supports it on
other architectures too, but presumably only for compatibility with x86
guests that also run on vmware.

CONFIG_PAGE_SIZE_64KB is used on hexagon, mips, sh and tile, the other
symbols are architecture-specific names for the same thing.

The driver may sleep under a spinlock.
The function call path is:
rr_close (acquire the spinlock)
  free_irq --> may sleep

To fix it, free_irq is moved to the place without holding the spinlock.

This bug is found by my static analysis tool(DSAC) and checked by my code review.

034317d43f gianfar: fix a flooded alignment reports because of padding issue.
[ Upstream commit 58117672943734715bbe7565ac9f062effa524f0 ]

According to LS1021A RM, the value of PAL can be set so that the start of the
IP header in the receive data buffer is aligned to a 32-bit boundary. Normally,
setting PAL = 2 provides minimal padding to ensure such alignment of the IP
header.

However every incoming packet's 8-byte time stamp will be inserted into the
packet data buffer as padding alignment bytes when hardware time stamping is
enabled.

So we set the padding 8+2 here to avoid the flooded alignment faults:

94abb49218 mvpp2: fix multicast address filter
commit 7ac8ff95f48cbfa609a060fd6a1e361dd62feeb3 upstream.

IPv6 doesn't work on the MacchiatoBIN board. It is caused by broken
multicast address filter in the mvpp2 driver.

The driver loads doesn't load any multicast entries if "allmulti" is not
set. This condition should be reversed.

The condition !netdev_mc_empty(dev) is useless (because
netdev_for_each_mc_addr is nop if the list is empty).

This patch also fixes a possible overflow of the multicast list - if
mvpp2_prs_mac_da_accept fails, we set the allmulti flag and retry.

4f62fb888d rtlwifi: rtl8821ae: Fix connection lost problem correctly
commit c713fb071edc0efc01a955f65a006b0e1795d2eb upstream.

There has been a coding error in rtl8821ae since it was first introduced,
namely that an 8-bit register was read using a 16-bit read in
_rtl8821ae_dbi_read(). This error was fixed with commit 40b368af4b75
("rtlwifi: Fix alignment issues"); however, this change led to
instability in the connection. To restore stability, this change
was reverted in commit b8b8b16352cd ("rtlwifi: rtl8821ae: Fix connection
lost problem").

Unfortunately, the unaligned access causes machine checks in ARM
architecture, and we were finally forced to find the actual cause of the
problem on x86 platforms. Following a suggestion from Pkshih
<pkshih@realtek.com>, it was found that increasing the ASPM L1
latency from 0 to 7 fixed the instability. This parameter was varied to
see if a smaller value would work; however, it appears that 7 is the
safest value. A new symbol is defined for this quantity, thus it can be
easily changed if necessary.

5b6e767562 IB/mlx4: Fix incorrectly releasing steerable UD QPs when have only ETH ports
commit 852f6927594d0d3e8632c889b2ab38cbc46476ad upstream.

Allocating steerable UD QPs depends on having at least one IB port,
while releasing those QPs does not.

As a result, when there are only ETH ports, the IB (RoCE) driver
requests releasing a qp range whose base qp is zero, with
qp count zero.

When SR-IOV is enabled, and the VF driver is running on a VM over
a hypervisor which treats such qp release calls as errors
(rather than NOPs), we see lines in the VM message log like:

 mlx4_core 0002:00:02.0: Failed to release qp range base:0 cnt:0

Fix this by adding a check for a zero count in mlx4_release_qp_range()
(which thus treats releasing 0 qps as a nop), and eliminating the
check for device managed flow steering when releasing steerable UD QPs.
(Freeing ib_uc_qpns_bitmap unconditionally is also OK, since it
remains NULL when steerable UD QPs are not allocated).

197ceb5fc0 net: cdc_ncm: initialize drvflags before usage
ctx->drvflags is checked in the if clause before beeing initialized.
Move initialization before first usage.

Note, that the if clause was backported with commit 75f82a703b
("cdc_ncm: Set NTB format again after altsetting switch for Huawei
devices") from mainline (upstream commit 2b02c20ce0c2 ("cdc_ncm: Set NTB
format again after altsetting switch for Huawei devices").  In mainline,
the initialization is at the right place before the if clause.

[ Upstream commit 15bfe05c8d6386f1a90e9340d15336e85e32aad6 ]

On 64-bit (e.g. powerpc64/allmodconfig):

			  ^

cdmac_bd.app4 is u32, so it is too small to hold a kernel pointer.

Note that several other fields in struct cdmac_bd are also too small to
hold physical addresses on 64-bit platforms.

49f1a164d4 xen-netfront: remove warning when unloading module
[ Upstream commit 5b5971df3bc2775107ddad164018a8a8db633b81 ]

v2:
 * Replace busy wait with wait_event()/wake_up_all()
 * Cannot garantee that at the time xennet_remove is called, the
   xen_netback state will not be XenbusStateClosed, so added a
   condition for that
 * There's a small chance for the xen_netback state is
   XenbusStateUnknown by the time the xen_netfront switches to Closed,
   so added a condition for that.

When unloading module xen_netfront from guest, dmesg would output
warning messages like below:

  [  105.236836] xen:grant_table: WARNING: g.e. 0x903 still in use!
  [  105.236839] deferring g.e. 0x903 (pfn 0x35805)

This problem relies on netfront and netback being out of sync. By the time
netfront revokes the g.e.'s netback didn't have enough time to free all of
them, hence displaying the warnings on dmesg.

The trick here is to make netfront to wait until netback frees all the g.e.'s
and only then continue to cleanup for the module removal, and this is done by
manipulating both device states.

As it turns out, normally the freeing of IRQs that would fix this is called
inside of the scope of __igb_close(). However, since the device is
already gone by the point we try to unregister the netdevice from the
driver due to a hotplug we end up seeing that the netif isn't present
and thus, forget to free any of the device IRQs.

So: make sure that if we're in the process of dismantling the netdev, we
always allow __igb_close() to be called so that IRQs may be freed
normally. Additionally, only allow igb_close() to be called from
__igb_close() if it hasn't already been called for the given adapter.

0d9bcadb22 vmxnet3: repair memory leak
[ Upstream commit 848b159835ddef99cc4193083f7e786c3992f580 ]

with the introduction of commit
b0eb57cb97, it appears that rq->buf_info
is improperly handled.  While it is heap allocated when an rx queue is
setup, and freed when torn down, an old line of code in
vmxnet3_rq_destroy was not properly removed, leading to rq->buf_info[0]
being set to NULL prior to its being freed, causing a memory leak, which
eventually exhausts the system on repeated create/destroy operations
(for example, when  the mtu of a vmxnet3 interface is changed
frequently.

Fix is pretty straight forward, just move the NULL set to after the
free.

Tested by myself with successful results

Applies to net, and should likely be queued for stable, please

a49558ebc2 pppoe: take ->needed_headroom of lower device into account on xmit
[ Upstream commit 02612bb05e51df8489db5e94d0cf8d1c81f87b0c ]

In pppoe_sendmsg(), reserving dev->hard_header_len bytes of headroom
was probably fine before the introduction of ->needed_headroom in
commit f5184d267c ("net: Allow netdevices to specify needed head/tailroom").

But now, virtual devices typically advertise the size of their overhead
in dev->needed_headroom, so we must also take it into account in
skb_reserve().
Allocation size of skb is also updated to take dev->needed_tailroom
into account and replace the arbitrary 32 bytes with the real size of
a PPPoE header.

This issue was discovered by syzbot, who connected a pppoe socket to a
gre device which had dev->header_ops->create == ipgre_header and
dev->hard_header_len == 0. Therefore, PPPoE didn't reserve any
headroom, and dev_hard_header() crashed when ipgre_header() tried to
prepend its header to skb->data.

Admittedly PPPoE shouldn't be allowed to run on non Ethernet-like
interfaces, but reserving space for ->needed_headroom is a more
fundamental issue that needs to be addressed first.

Same problem exists for __pppoe_xmit(), which also needs to take
dev->needed_headroom into account in skb_cow_head().

commit d8a243af1a68395e07ac85384a2740d4134c67f4 upstream.

In some rare conditions when running one PEAK USB-FD interface over
a non high-speed USB controller, one useless USB fragment might be sent.
This patch fixes the way a USB command is fragmented when its length is
greater than 64 bytes and when the underlying USB controller is not a
high-speed one.

cf9f240627 e1000e: Fix e1000_check_for_copper_link_ich8lan return value.
commit 4110e02eb45ea447ec6f5459c9934de0a273fb91 upstream.

e1000e_check_for_copper_link() and e1000_check_for_copper_link_ich8lan()
are the two functions that may be assigned to mac.ops.check_for_link when
phy.media_type == e1000_media_type_copper. Commit 19110cfbb34d ("e1000e:
Separate signaling for link check/link up") changed the meaning of the
return value of check_for_link for copper media but only adjusted the first
function. This patch adjusts the second function likewise.

b188ce30cc net: stmmac: enable EEE in MII, GMII or RGMII only
[ Upstream commit 879626e3a52630316d817cbda7cec9a5446d1d82 ]

Note in the databook - Section 4.4 - EEE :
" The EEE feature is not supported when the MAC is configured to use the
TBI, RTBI, SMII, RMII or SGMII single PHY interface. Even if the MAC
supports multiple PHY interfaces, you should activate the EEE mode only
when the MAC is operating with GMII, MII, or RGMII interface."

Applying this restriction solves a stability issue observed on Amlogic
gxl platforms operating with RMII interface and the internal PHY.

f574e2e8c6 sh_eth: fix SH7757 GEther initialization
[ Upstream commit 5133550296d43236439494aa955bfb765a89f615 ]

Renesas  SH7757 has 2 Fast and 2 Gigabit Ether controllers, while the
'sh_eth' driver can only reset and initialize TSU of the first controller
pair. Shimoda-san tried to solve that adding the 'needs_init' member to the
'struct sh_eth_plat_data', however the platform code still never sets this
flag. I think  that we can infer this information from the 'devno' variable
(set  to 'platform_device::id') and reset/init the Ether controller pair
only for an even 'devno'; therefore 'sh_eth_plat_data::needs_init' can be
removed...

29ca856bb7 sh_eth: fix TSU resource handling
[ Upstream commit dfe8266b8dd10e12a731c985b725fcf7f0e537f0 ]

When switching  the driver to the managed device API,  I managed to break
the  case of a  dual Ether devices sharing a single TSU: the 2nd Ether port
wouldn't probe. Iwamatsu-san has tried to fix this but his patch was buggy
and he then dropped the ball...

The solution is to  limit calling devm_request_mem_region() to the first
of  the two  ports  sharing the same TSU, so devm_ioremap_resource() can't
be used anymore for the TSU resource...

146001aeb9 cx82310_eth: use skb_cow_head() to deal with cloned skbs
commit a9e840a2081ed28c2b7caa6a9a0041c950b3c37d upstream.

We need to ensure there is enough headroom to push extra header,
but we also need to check if we are allowed to change headers.

skb_cow_head() is the proper helper to deal with this.
