Function 'udp_tunnel6_xmit_skb' had been redefined in commit 4d5805d.
Compat hack must be removed to fix compilation issue.

This patch extends udp_tunnel6_xmit_skb() to pass in the IPv6 flow label
from call sites. Currently, there's no such option and it's always set to
zero when writing ip6_flow_hdr(). Add a label member to ip_tunnel_key, so
that flow-based tunnels via collect metadata frontends can make use of it.
vxlan and geneve will be converted to add flow label support separately.

After eBPF being able to programmatically access/manage tunnel key meta
data via commit d3aa45ce6b94 ("bpf: add helpers to access tunnel metadata")
and more recently also for IPv6 through c6c33454072f ("bpf: support ipv6
for bpf_skb_{set,get}_tunnel_key"), this work adds two complementary
helpers to generically access their auxiliary tunnel options.
Geneve and vxlan support this facility. For geneve, TLVs can be pushed,
and for the vxlan case its GBP extension. I.e. setting tunnel key for geneve
case only makes sense, if we can also read/write TLVs into it. In the GBP
case, it provides the flexibility to easily map the group policy ID in
combination with other helpers or maps.
I chose to model this as two separate helpers, bpf_skb_{set,get}_tunnel_opt(),
for a couple of reasons. bpf_skb_{set,get}_tunnel_key() is already rather
complex by itself, and there may be cases for tunnel key backends where
tunnel options are not always needed. If we would have integrated this
into bpf_skb_{set,get}_tunnel_key() nevertheless, we are very limited with
remaining helper arguments, so keeping compatibility on structs in case of
passing in a flat buffer gets more cumbersome. Separating both also allows
for more flexibility and future extensibility, f.e. options could be fed
directly from a map, etc.
Moreover, change geneve's xmit path to test only for info->options_len
instead of TUNNEL_GENEVE_OPT flag. This makes it more consistent with vxlan's
xmit path and allows for avoiding to specify a protocol flag in the API on
xmit, so it can be protocol agnostic. Having info->options_len is enough
information that is needed. Tested with vxlan and geneve.

This reverts commit 5a5abb1fa3b05dd ("tun, bpf: fix suspicious RCU usage
in tun_{attach, detach}_filter") and replaces it to use lock_sock around
sk_{attach,detach}_filter. The checks inside filter.c are updated with
lockdep_sock_is_held to check for proper socket locks.
It keeps the code cleaner by ensuring that only one lock governs the
socket filter instead of two independent locks.

commit 99218cbf81bf21355a3de61cd46a706d36e900e6 upstream.
platform_get_irq() returns negative error number instead 0 on failure.
And the doc of platform_get_irq() provides a usage example:
int irq = platform_get_irq(pdev, 0);
if (irq < 0)
return irq;
Fix the check of return value to catch errors correctly.

commit 9deb48b53e7f4056c2eaa2dc2ee3338df619e4f6 upstream.
The driver neglects to check the result of platform_get_irq_optional()'s
call and blithely passes the negative error codes to devm_request_irq()
(which takes *unsigned* IRQ #), causing it to fail with -EINVAL.
Stop calling devm_request_irq() with the invalid IRQ #s.

commit aba57a823d2985a2cc8c74a2535f3a88e68d9424 upstream.
The check for the number of available TX ring slots was off by 1 since a
slot is required for the skb header as well as each fragment. This could
result in overwriting a TX ring slot that was still in use.

commit b400c2f4f4c53c86594dd57098970d97d488bfde upstream.
When resetting the device, wait for the PhyRstCmplt bit to be set
in the interrupt status register before continuing initialization, to
ensure that the core is actually ready. When using an external PHY, this
also ensures we do not start trying to access the PHY while it is still
in reset. The PHY reset is initiated by the core reset which is
triggered just above, but remains asserted for 5ms after the core is
reset according to the documentation.
The MgtRdy bit could also be waited for, but unfortunately when using
7-series devices, the bit does not appear to work as documented (it
seems to behave as some sort of link state indication and not just an
indication the transceiver is ready) so it can't really be relied on for
this purpose.

[ Upstream commit 6ce708f54cc8d73beca213cec66ede5ce100a781 ]
Large pkt_len can lead to out-out-bound memcpy. Current
ath9k_hif_usb_rx_stream allows combining the content of two urb
inputs to one pkt. The first input can indicate the size of the
pkt. Any remaining size is saved in hif_dev->rx_remain_len.
While processing the next input, memcpy is used with rx_remain_len.
4-byte pkt_len can go up to 0xffff, while a single input is 0x4000
maximum in size (MAX_RX_BUF_SIZE). Thus, the patch adds a check for
pkt_len which must not exceed 2 * MAX_RX_BUG_SIZE.

I found the bug using a custome USBFuzz port. It's a research work
to fuzz USB stack/drivers. I modified it to fuzz ath9k driver only,
providing hand-crafted usb descriptors to QEMU.
After fixing the value of pkt_tag to ATH_USB_RX_STREAM_MODE_TAG in QEMU
emulation, I found the KASAN report. The bug is triggerable whenever
pkt_len is above two MAX_RX_BUG_SIZE. I used the same input that crashes
to test the driver works when applying the patch.

[ Upstream commit db66abeea3aefed481391ecc564fb7b7fb31d742 ]
If userspace installs a lot of multicast groups very quickly, then
we may run out of command queue space as we send the updates in an
asynchronous fashion (due to locking concerns), and the CPU can
create them faster than the firmware can process them. This is true
even when mac80211 has a work struct that gets scheduled.
Fix this by synchronizing with the firmware after sending all those
commands - outside of the iteration we can send a synchronous echo
command that just has the effect of the CPU waiting for the prior
asynchronous commands to finish. This also will cause fewer of the
commands to be sent to the firmware overall, because the work will
only run once when rescheduled multiple times while it's running.

Syzbot reported uninit value in mcs7830_bind(). The problem was in
missing validation check for bytes read via usbnet_read_cmd().
usbnet_read_cmd() internally calls usb_control_msg(), that returns
number of bytes read. Code should validate that requested number of bytes
was actually read.
So, this patch adds missing size validation check inside
mcs7830_get_reg() to prevent uninit value bugs

For the possible failure of the platform_get_irq(), the returned irq
could be error number and will finally cause the failure of the
request_irq().
Consider that platform_get_irq() can now in certain cases return
-EPROBE_DEFER, and the consequences of letting request_irq()
effectively convert that into -EINVAL, even at probe time rather than
later on. So it might be better to check just now.

remove the comment, activate the code, but add a "0 &&" to the if
expression and rely on the optimizer rather than the preprocessor to
remove the code.

[ Upstream commit 44073187990d5629804ce0627525f6ea5cfef171 ]
It seems pretty clear ppp layer assumed user space
would always be kind to provide enough data
in their write() to a ppp device.
This patch makes sure user provides at least
2 bytes.
It adds PPP_PROTO_LEN macro that could replace
in net-next many occurrences of hard-coded 2 value.
I replaced only one occurrence to ease backports
to stable kernels.
The bug manifests in the following report:

commit ced4913efb0acc844ed65cc01d091a85d83a2082 upstream.
In case device registration fails during probe, the driver state and
the embedded platform device structure needs to be freed using
platform_device_put() to properly free all resources (e.g. the device
name).

commit 8b144dedb928e4e2f433a328d58f44c3c098d63e upstream.
Syzbot reports the following WARNING:
[200~raw_local_irq_restore() called with IRQs enabled
WARNING: CPU: 1 PID: 1206 at kernel/locking/irqflag-debug.c:10
warn_bogus_irq_restore+0x1d/0x20 kernel/locking/irqflag-debug.c:10
Hardware initialization for the rtl8188cu can run for as long as 350 ms,
and the routine may be called with interrupts disabled. To avoid locking
the machine for this long, the current routine saves the interrupt flags
and enables local interrupts. The problem is that it restores the flags
at the end without disabling local interrupts first.
This patch fixes commit a53268be0cb9 ("rtlwifi: rtl8192cu: Fix too long

commit 89d58aebe14a365c25ba6645414afdbf4e41cea4 upstream.
No information is deliberately sent in hf->flags in host -> device
communications, but the open-source candleLight firmware echoes it
back, which can result in the GS_CAN_FLAG_OVERFLOW flag being set and
generating spurious ERRORFRAMEs.
While there also initialize the reserved member with 0.

commit 29262e1f773b4b6a43711120be564c57fca07cfb upstream.
Hytera makes a range of digital (DMR) radios. These radios can be
programmed to a allow a computer to control them over Ethernet over USB,
either using NCM or RNDIS.
This commit adds support for RNDIS for Hytera radios. I tested with a
Hytera PD785 and a Hytera MD785G. When these radios are programmed to
set up a Radio to PC Network using RNDIS, an USB interface will be added
with class 2 (Communications), subclass 2 (Abstract Modem Control) and
an interface protocol of 255 ("vendor specific" - lsusb even hints "MSFT
RNDIS?").
This patch is similar to the solution of this StackOverflow user, but
that only works for the Hytera MD785:
https://stackoverflow.com/a/53550858
To use the "Radio to PC Network" functionality of Hytera DMR radios, the
radios need to be programmed correctly in CPS (Hytera's Customer
Programming Software). "Forward to PC" should be checked in "Network"
(under "General Setting" in "Conventional") and the "USB Network
Communication Protocol" should be set to RNDIS.

commit e738451d78b2f8a9635d66c6a87f304b4d965f7a upstream.
There was a wrong queues representation in sysfs during
driver's reinitialization in case of online cpus number is
less than combined queues. It was caused by stopped
NetworkManager, which is responsible for calling vsi_open
function during driver's initialization.
In specific situation (ex. 12 cpus online) there were 16 queues
in /sys/class/net/<iface>/queues. In case of modifying queues with
value higher, than number of online cpus, then it caused write
errors and other errors.
Add updating of sysfs's queues representation during driver
initialization.

commit 754e4382354f7908923a1949d8dc8d05f82f09cb upstream.
Alexander reported a use of uninitialized value in
atusb_set_extended_addr(), that is caused by reading 0 bytes via
usb_control_msg().
Fix it by validating if the number of bytes transferred is actually
correct, since usb_control_msg() may read less bytes, than was requested
by caller.

commit b2f37aead1b82a770c48b5d583f35ec22aabb61e upstream.
The previous commit 3e0588c291d6 ("hamradio: defer ax25 kfree after
unregister_netdev") reorder the kfree operations and unregister_netdev
operation to prevent UAF.
This commit improves the previous one by also deferring the nullify of
the ax->tty pointer. Otherwise, a NULL pointer dereference bug occurs.
Partial of the stack trace is shown below.

pointer won't be assigned as NULL net_device framework layer is well
synchronized.

commit 3e0588c291d6ce225f2b891753ca41d45ba42469 upstream.
There is a possible race condition (use-after-free) like below
(USE) | (FREE)
ax25_sendmsg |
ax25_queue_xmit |
dev_queue_xmit |
__dev_queue_xmit |
__dev_xmit_skb |
sch_direct_xmit | ...
xmit_one |
netdev_start_xmit | tty_ldisc_kill
__netdev_start_xmit | mkiss_close
ax_xmit | kfree
ax_encaps |
|
Even though there are two synchronization primitives before the kfree:
1. wait_for_completion(&ax->dead). This can prevent the race with
routines from mkiss_ioctl. However, it cannot stop the routine coming
from upper layer, i.e., the ax25_sendmsg.
2. netif_stop_queue(ax->dev). It seems that this line of code aims to
halt the transmit queue but it fails to stop the routine that already
being xmit.
This patch reorder the kfree after the unregister_netdev to avoid the
possible UAF as the unregister_netdev() is well synchronized and won't
return if there is a running routine.

[ Upstream commit cb93b3e11d405f20a405a07482d01147ef4934a3 ]
Because platform_get_irq() could fail and return error irq.
Therefore, it might be better to check it if order to avoid the use of
error irq.

When 802.3ad bond mode is configured the ad_actor_system option is set to
"00:00:00:00:00:00". But when trying to set the all-zeroes MAC as actors'
system address it was failing with EINVAL.
An all-zeroes ethernet address is valid, only multicast addresses are not
valid values.

[ Upstream commit 60ec7fcfe76892a1479afab51ff17a4281923156 ]
The return value of kcalloc() needs to be checked.
To avoid dereference of null pointer in case of the failure of alloc.
Therefore, it might be better to change the return type of
qlcnic_sriov_alloc_vlans() and return -ENOMEM when alloc fails and
return 0 the others.
Also, qlcnic_sriov_set_guest_vlan_mode() and __qlcnic_pci_sriov_enable()
should deal with the return value of qlcnic_sriov_alloc_vlans().

commit fb12797ab1fef480ad8a32a30984844444eeb00d upstream.
The CAN clock frequency is used when calculating the CAN bittiming
parameters. When wrong clock frequency is used, the device may end up
with wrong bittiming parameters, depending on user requested bittiming
parameters.
To avoid this, get the CAN clock frequency from the device. Various
existing Kvaser Leaf products use different CAN clocks.

commit be81992f9086b230623ae3ebbc85ecee4d00a3d3 upstream.
In case a guest isn't consuming incoming network traffic as fast as it
is coming in, xen-netback is buffering network packages in unlimited
numbers today. This can result in host OOM situations.
Commit f48da8b14d04ca8 ("xen-netback: fix unlimited guest Rx internal
queue and carrier flapping") meant to introduce a mechanism to limit
the amount of buffered data by stopping the Tx queue when reaching the
data limit, but this doesn't work for cases like UDP.
When hitting the limit don't queue further SKBs, but drop them instead.
In order to be able to tell Rx packages have been dropped increment the
rx_dropped statistics counter in this case.
It should be noted that the old solution to continue queueing SKBs had
the additional problem of an overflow of the 32-bit rx_queue_len value
would result in intermittent Tx queue enabling.
This is part of XSA-392

commit b27d47950e481f292c0a5ad57357edb9d95d03ba upstream.
The Xen netfront driver is still vulnerable for an attack via excessive
number of events sent by the backend. Fix that by using lateeoi event
channels.
For being able to detect the case of no rx responses being added while
the carrier is down a new lock is needed in order to update and test
rsp_cons and the number of seen unconsumed responses atomically.

commit 8b8e6e782456f1ce02a7ae914bbd5b1053f0b034 upstream.
The descriptor list is a shared resource across all of the transmit queues, and
the locking mechanism used today only protects concurrency across a given
transmit queue between the transmit and reclaiming. This creates an opportunity
for the SYSTEMPORT hardware to work on corrupted descriptors if we have
multiple producers at once which is the case when using multiple transmit
queues.
This was particularly noticeable when using multiple flows/transmit queues and
it showed up in interesting ways in that UDP packets would get a correct UDP
header checksum being calculated over an incorrect packet length. Similarly TCP
packets would get an equally correct checksum computed by the hardware over an
incorrect packet length.
The SYSTEMPORT hardware maintains an internal descriptor list that it re-arranges
when the driver produces a new descriptor anytime it writes to the
WRITE_PORT_{HI,LO} registers, there is however some delay in the hardware to
re-organize its descriptors and it is possible that concurrent TX queues
eventually break this internal allocation scheme to the point where the
length/status part of the descriptor gets used for an incorrect data buffer.
The fix is to impose a global serialization for all TX queues in the short
section where we are writing to the WRITE_PORT_{HI,LO} registers which solves
the corruption even with multiple concurrent TX queues being used.

[ Upstream commit b6d335a60dc624c0d279333b22c737faa765b028 ]
In `igbvf_probe`, if register_netdev() fails, the program will go to
label err_hw_init, and then to label err_ioremap. In free_netdev() which
is just below label err_ioremap, there is `list_for_each_entry_safe` and
`netif_napi_del` which aims to delete all entries in `dev->napi_list`.
The program has added an entry `adapter->rx_ring->napi` which is added by
`netif_napi_add` in igbvf_alloc_queues(). However, adapter->rx_ring has
been freed below label err_hw_init. So this a UAF.
In terms of how to patch the problem, we can refer to igbvf_remove() and
delete the entry before `adapter->rx_ring`.

commit d17b9737c2bc09b4ac6caf469826e5a7ce3ffab7 upstream.
The ql_wait_for_drvr_lock() fails and returns false, then this
function should return an error code instead of returning success.
The other problem is that the success path prints an error message
netdev_err(ndev, "Releasing driver lock\n"); Delete that and
re-order the code a little to make it more clear.

commit b5bd95d17102b6719e3531d627875b9690371383 upstream.
Background:
We have a customer is running a Profinet stack on the 8MM which receives and
responds PNIO packets every 4ms and PNIO-CM packets every 40ms. However, from
time to time the received PNIO-CM package is "stock" and is only handled when
receiving a new PNIO-CM or DCERPC-Ping packet (tcpdump shows the PNIO-CM and
the DCERPC-Ping packet at the same time but the PNIO-CM HW timestamp is from
the expected 40 ms and not the 2s delay of the DCERPC-Ping).
After debugging, we noticed PNIO, PNIO-CM and DCERPC-Ping packets would
be handled by different RX queues.
The root cause should be driver ack all queues' interrupt when handle a
specific queue in fec_enet_rx_queue(). The blamed patch is introduced to
receive as much packets as possible once to avoid interrupt flooding.
But it's unreasonable to clear other queues'interrupt when handling one
queue, this patch tries to fix it.
Fixes: ed63f1dcd578 (net: fec: clear receive interrupts before processing a packet)

commit badd7857f5c933a3dc34942a2c11d67fdbdc24de upstream.
There are two error paths which accidentally return success instead of
a negative error code.
