[ Upstream commit aa604651d523b1493988d0bf6710339f3ee60272 ]
Currently, though the FDB entry is added to VF, it does not appear in
RAR filters. VF driver only allows to add 10 entries. Attempting to add
another causes an error. This patch removes limitation and allows use of
all free RAR entries for the FDB if needed.

[ Upstream commit 00c0688cecadbf7ac2f5b4cdb36d912a2d3f0cca ]
Since net_device.mem_start is unsigned long, it should not be cast to
int right before casting to pointer. This fixes warning (compile
testing on alpha architecture):
drivers/net/wan/sdla.c: In function ‘sdla_transmit’:
drivers/net/wan/sdla.c:711:13: warning:
cast to pointer from integer of different size [-Wint-to-pointer-cast]

[ Upstream commit f11421ba4af706cb4f5703de34fa77fba8472776 ]
Atomic operations that span cache lines are super-expensive on x86
(not just to the current processor, but also to other processes as all
memory operations are blocked until the operation completes). Upcoming
x86 processors have a switch to cause such operations to generate a #AC
trap. It is expected that some real time systems will enable this mode
in BIOS.
In preparation for this, it is necessary to fix code that may execute
atomic instructions with operands that cross cachelines because the #AC
trap will crash the kernel.
Since "pwol_mask" is local and never exposed to concurrency, there is
no need to set bits in pwol_mask using atomic operations.
Directly operate on the byte which contains the bit instead of using
__set_bit() to avoid any big endian concern due to type cast to
unsigned long in __set_bit().

commit 2d68bb2687abb747558b933e80845ff31570a49c upstream.
Make sure to use the current alternate setting when verifying the
storage interface descriptors to avoid submitting an URB to an invalid
endpoint.
Failing to do so could cause the driver to misbehave or trigger a WARN()
in usb_submit_urb() that kernels with panic_on_warn set would choke on.

commit e5e884b42639c74b5b57dc277909915c0aefc8bb upstream.
add_ie_rates() copys rates without checking the length
in bss descriptor from remote AP.when victim connects to
remote attacker, this may trigger buffer overflow.
lbs_ibss_join_existing() copys rates without checking the length
in bss descriptor from remote IBSS node.when victim connects to
remote attacker, this may trigger buffer overflow.
Fix them by putting the length check before performing copy.
This fix addresses CVE-2019-14896 and CVE-2019-14897.
This also fix build warning of mixed declarations and code.

[ Upstream commit ce896476c65d72b4b99fa09c2f33436b4198f034 ]
As reported by Eric Dumazet, there are still some outstanding
cases where the driver does not handle TSO correctly when skb's
are over a certain size. Most cases have been fixed, this patch
should ensure that forwarded SKB's that are greater than
MAX_SINGLE_PACKET_SIZE - TX_OVERHEAD are software segmented
and handled correctly.

[ Upstream commit 3546d8f1bbe992488ed91592cf6bf76e7114791a =
The cxgb3 driver for "Chelsio T3-based gigabit and 10Gb Ethernet
adapters" implements a custom ioctl as SIOCCHIOCTL/SIOCDEVPRIVATE in
cxgb_extension_ioctl().
One of the subcommands of the ioctl is CHELSIO_GET_MEM, which appears
to read memory directly out of the adapter and return it to userspace.
It's not entirely clear what the contents of the adapter memory
contains, but the assumption is that it shouldn't be accessible to all
users.
So add a CAP_NET_ADMIN check to the CHELSIO_GET_MEM case. Put it after
the is_offload() check, which matches two of the other subcommands in
the same function which also check for is_offload() and CAP_NET_ADMIN.
Found by Ilja by code inspection, not tested as I don't have the
required hardware.

[ Upstream commit 0ace17d56824165c7f4c68785d6b58971db954dd ]
write_wakeup can happen in parallel with close/hangup where tty->disc_data
is set to NULL and the netdevice is freed thus also freeing
disc_data. write_wakeup accesses disc_data so we must prevent close from
freeing the netdev while write_wakeup has a non-NULL view of
tty->disc_data.
We also need to make sure that accesses to disc_data are atomic. Which can
all be done with RCU.
This problem was found by Syzkaller on SLCAN, but the same issue is
reproducible with the SLIP line discipline using an LTP test based on the
Syzkaller reproducer.
A fix which didn't use RCU was posted by Hillf Danton.

[ Upstream commit 5da202c88f8c355ad79bc2e8eb582e6d433060e7 ]
The field "name" in struct ptp_clock_info has a fixed size of 16
chars and is used as zero terminated string by clock_name_show()
in drivers/ptp/ptp_sysfs.c
The current initialization value requires 17 chars to fit also the
null termination, and this causes overflow to the next bytes in
the struct when the string is read as null terminated:
hexdump -C /sys/class/ptp/ptp0/clock_name
00000000 73 74 6d 6d 61 63 5f 70 74 70 5f 63 6c 6f 63 6b |stmmac_ptp_clock|
00000010 a0 ac b9 03 0a |.....|
where the extra 4 bytes (excluding the newline) after the string
represent the integer 0x03b9aca0 = 62500000 assigned to the field
"max_adj" that follows "name" in the same struct.
There is no strict requirement for the "name" content and in the
comment in ptp_clock_kernel.h it's reported it should just be 'A
short "friendly name" to identify the clock'.
Replace it with "stmmac ptp".

[ Upstream commit f8d7408a4d7f60f8b2df0f81decdc882dd9c20dc ]
lan78xx_tx_bh() makes sure to not exceed MAX_SINGLE_PACKET_SIZE
bytes in the aggregated packets it builds, but does
nothing to prevent large GSO packets being submitted.
Pierre-Francois reported various hangs when/if TSO is enabled.
For localy generated packets, we can use netif_set_gso_max_size()
to limit the size of TSO packets.
Note that forwarded packets could still hit the issue,
so a complete fix might require implementing .ndo_features_check
for this driver, forcing a software segmentation if the size
of the TSO packet exceeds MAX_SINGLE_PACKET_SIZE.

commit 6e41e2257f1094acc37618bf6c856115374c6922 upstream.
The syzbot fuzzer found a bug in the p54 USB wireless driver. The
issue involves a race between disconnect and the firmware-loader
callback routine, and it has several aspects.
One big problem is that when the firmware can't be loaded, the
callback routine tries to unbind the driver from the USB _device_ (by
calling device_release_driver) instead of from the USB _interface_ to
which it is actually bound (by calling usb_driver_release_interface).
The race involves access to the private data structure. The driver's
disconnect handler waits for a completion that is signalled by the
firmware-loader callback routine. As soon as the completion is
signalled, you have to assume that the private data structure may have
been deallocated by the disconnect handler -- even if the firmware was
loaded without errors. However, the callback routine does access the
private data several times after that point.
Another problem is that, in order to ensure that the USB device
structure hasn't been freed when the callback routine runs, the driver
takes a reference to it. This isn't good enough any more, because now
that the callback routine calls usb_driver_release_interface, it has
to ensure that the interface structure hasn't been freed.
Finally, the driver takes an unnecessary reference to the USB device
structure in the probe function and drops the reference in the
disconnect handler. This extra reference doesn't accomplish anything,
because the USB core already guarantees that a device structure won't
be deallocated while a driver is still bound to any of its interfaces.
To fix these problems, this patch makes the following changes:
Call usb_driver_release_interface() rather than
device_release_driver().
Don't signal the completion until after the important
information has been copied out of the private data structure,
and don't refer to the private data at all thereafter.
Lock udev (the interface's parent) before unbinding the driver
instead of locking udev->parent.
During the firmware loading process, take a reference to the
USB interface instead of the USB device.
Don't take an unnecessary reference to the device during probe
(and then don't drop it during disconnect).

commit abd39c6ded9db53aa44c2540092bdd5fb6590fa8 upstream.
Observed crash in some scenarios when assertion has occurred,
this is because hw structure is freed and is tried to get
accessed in some functions where null check is already
present. So, avoided the crash by making the hw to NULL after
freeing.

commit 3d94a4a8373bf5f45cf5f939e88b8354dbf2311b upstream.
mwifiex_process_country_ie() function parse elements of bss
descriptor in beacon packet. When processing WLAN_EID_COUNTRY
element, there is no upper limit check for country_ie_len before
calling memcpy. The destination buffer domain_info->triplet is an
array of length MWIFIEX_MAX_TRIPLET_802_11D(83). The remote
attacker can build a fake AP with the same ssid as real AP, and
send malicous beacon packet with long WLAN_EID_COUNTRY elemen
(country_ie_len > 83). Attacker can force STA connect to fake AP
on a different channel. When the victim STA connects to fake AP,
will trigger the heap buffer overflow. Fix this by checking for
length and if found invalid, don not connect to the AP.
This fix addresses CVE-2019-14895.

to irq mode
commit 2d77bd61a2927be8f4e00d9478fe6996c47e8d45 upstream.
Under load, the RX side of the mscan driver can get stuck while TX still
works. Restarting the interface locks up the system. This behaviour
could be reproduced reliably on a MPC5121e based system.
The patch fixes the return value of the NAPI polling function (should be
the number of processed packets, not constant 1) and the condition under
which IRQs are enabled again after polling is finished.
With this patch, no more lockups were observed over a test period of ten
days.

[ Upstream commit 96cc4b69581db68efc9749ef32e9cf8e0160c509 ]
Use of eth_hdr() in tx path is error prone.
Many drivers call skb_reset_mac_header() before using it,
but others do not.
Commit 6d1ccff62780 ("net: reset mac header in dev_start_xmit()")
attempted to fix this generically, but commit d346a3fae3ff
("packet: introduce PACKET_QDISC_BYPASS socket option") brought
back the macvlan bug.
Lets add a new helper, so that tx paths no longer have
to call skb_reset_mac_header() only to get a pointer
to skb->data.
Hopefully we will be able to revert 6d1ccff62780
("net: reset mac header in dev_start_xmit()") and save few cycles
in transmit fast path.

[ Upstream commit 71130f29979c7c7956b040673e6b9d5643003176 ]
Before ip_tunnel_ecn_encap() and udp_tunnel_xmit_skb() we should filter
tos value by RT_TOS() instead of using config tos directly.
vxlan_get_route() would filter the tos to fl4.flowi4_tos but we didn't
return it back, as geneve_get_v4_rt() did. So we have to use RT_TOS()
directly in function ip_tunnel_ecn_encap().

cases the PHY's internal delay for both RX and TX are used.
