[ Upstream commit a3e5fd9314dfc4314a9567cde96e1aef83a7458a ]
When adding a hairpin flow, a firmware-side send queue is created for
the peer net device, which claims some host memory pages for its
internal ring buffer. If the peer net device is removed/unbound before
the hairpin flow is deleted, then the send queue is not destroyed which
leads to a stack trace on pci device remove:

[ Upstream commit 8ad893e516a77209a1818a2072d2027d87db809f ]
Currently, IPsec feature is disabled because mlx5e_build_nic_netdev
is required to be called after mlx5e_ipsec_init. This requirement is
invalid as mlx5e_build_nic_netdev and mlx5e_ipsec_init initialize
independent resources.
Remove ipsec pointer check in mlx5e_build_nic_netdev so that the
two functions can be called at any order.

[ Upstream commit 2e84f6b3773f43263124c76499c0c4ec3f40aa9b ]
Commit ae15e0ba1b33 ("ice: Change number of XDP Tx queues to match
number of Rx queues") tried to address the incorrect setting of XDP
queue count that was based on the Tx queue count, whereas in theory we
should provide the XDP queue per Rx queue. However, the routines that
setup and destroy the set of Tx resources are still based on the
vsi->num_txq.
Ice supports the asynchronous Tx/Rx queue count, so for a setup where
vsi->num_txq > vsi->num_rxq, ice_vsi_stop_tx_rings and ice_vsi_cfg_txqs
will be accessing the vsi->xdp_rings out of the bounds.
Parameterize two mentioned functions so they get the size of Tx resources
array as the input.

[ Upstream commit ebc5399ea1dfcddac31974091086a3379141899b ]
ice driver requires a programmable pipeline firmware package in order to
have a support for advanced features. Otherwise, driver falls back to so
called 'safe mode'. For that mode, ndo_bpf callback is not exposed and
when user tries to load XDP program, the following happens:
$ sudo ./xdp1 enp179s0f1
libbpf: Kernel error message: Underlying driver does not support XDP in native mode
link set xdp fd failed
which is sort of confusing, as there is a native XDP support, but not in
the current mode. Improve the user experience by providing the specific
ndo_bpf callback dedicated for safe mode which will make use of extack
to explicitly let the user know that the DDP package is missing and
that's the reason that the XDP can't be loaded onto interface currently.

[ Upstream commit f2386cf7c5f4ff5d7b584f5d92014edd7df6c676 ]
This patch fixes TX hangs with threaded NAPI enabled. The scheduled
NAPI seems to be executed in parallel with the interrupt on second
thread. Sometimes it happens that ltq_dma_disable_irq() is executed
after xrx200_tx_housekeeping(). The symptom is that TX interrupts
are disabled in the DMA controller. As a result, the TX hangs after
a few seconds of the iperf test. Scheduling NAPI after disabling
interrupts fixes this issue.
Tested on Lantiq xRX200 (BT Home Hub 5A).

[ Upstream commit 9bb392f62447d73cc7dd7562413a2cd9104c82f8 ]
My initial goal was to fix the default MTU, which is set to 65536, ie above
the maximum defined in the driver: 65535 (ETH_MAX_MTU).
In fact, it's seems more consistent, wrt min_mtu, to set the max_mtu to
IP6_MAX_MTU (65535 + sizeof(struct ipv6hdr)) and use it by default.
Let's also, for consistency, set the mtu in vrf_setup(). This function
calls ether_setup(), which set the mtu to 1500. Thus, the whole mtu config
is done in the same function.
Before the patch:
$ ip link add blue type vrf table 1234
$ ip link list blue
9: blue: <NOARP,MASTER> mtu 65536 qdisc noop state DOWN mode DEFAULT group default qlen 1000
link/ether fa:f5:27:70:24:2a brd ff:ff:ff:ff:ff:ff
$ ip link set dev blue mtu 65535
$ ip link set dev blue mtu 65536
Error: mtu greater than device maximum.

used to be initialized with zero value, while actual delay was used to
be set by mlxsw_thermal_set_mode() by thermal operation callback

cited commits, modules and gearboxes thermal zones always have polling
time set to zero and do not perform temperature monitoring.

thus, the relevant thermal zones will perform thermal monitoring.

[ Upstream commit 306b9228c097b4101c150ccd262372ded8348644 ]
A max-shaper is the HW component responsible for delaying egress traffic
above a configured transmission rate. Burst size is the amount of traffic
that is allowed to pass without accounting. The burst size value needs to
be such that it can be expressed as 2^BS * 512 bits, where BS lies in a
certain ASIC-dependent range. mlxsw enforces that this holds before
attempting to configure the shaper.
The assumption for Spectrum-3 was that the lower limit of BS would be 5,
like for Spectrum-1. But as of now, the limit is still 11. Therefore fix
the driver accordingly, so that incorrect values are rejected early with a
proper message.

xilinx_dpdma_irq_handler is invoked to access xdev->chan[i]. But at
this moment xdev->chan[i] hasn't been initialized.
We should ensure the dpdma controller to be in a consistent and
clean state before further initialization. So add dpdma_hw_init()
to do this.
Furthermore, in xilinx_dpdma_disable_irq, disable all interrupts
instead of error interrupts.
This patch is to fix the kdump kernel crash as below:

In some cases we may need to initialize the host1x client first before
registering it. This commit adds a new helper that will do nothing but
the initialization of the data structure.
At the same time, the initialization is removed from the registration
function. Note, however, that for simplicity we explicitly initialize
the client when the host1x_client_register() function is called, as
opposed to the low-level __host1x_client_register() function. This
allows existing callers to remain unchanged.

It's theoretically possible for the runtime PM reference to leak if the
code fails anywhere between the pm_runtime_resume_and_get() and
pm_runtime_put() calls, so make sure to release the runtime PM reference

Practically this will never happen because none of the functions will
fail on Tegra, but it's better for the code to be pedantic in case these
assumptions will ever become wrong.

In hid_submit_ctrl(), the way of calculating the report length doesn't
take into account that report->size can be zero. When running the
syzkaller reproducer, a report of size 0 causes hid_submit_ctrl) to
calculate transfer_buffer_length as 16384. When this urb is passed to
the usb core layer, KMSAN reports an info leak of 16384 bytes.
To fix this, first modify hid_report_len() to account for the zero
report size case by using DIV_ROUND_UP for the division. Then, call it
from hid_submit_ctrl().

commit 11714026c02d613c30a149c3f4c4a15047744529 upstream.
scsi_host_dev_release() only frees dev_name when host state is
SHOST_CREATED. After host state has changed to SHOST_RUNNING,
scsi_host_dev_release() no longer cleans up.
Fix this by doing a put_device(&shost->shost_dev) in the failure path when
host state is SHOST_RUNNING. Move get_device(&shost->shost_gendev) before
device_add(&shost->shost_dev) so that scsi_host_cls_release() can do a put
on this reference.

commit 3719f4ff047e20062b8314c23ec3cab84d74c908 upstream.
When scsi_add_host_with_dma() returns failure, the caller will call
scsi_host_put(shost) to release everything allocated for this host
instance. Consequently we can't also free allocated stuff in
scsi_add_host_with_dma(), otherwise we will end up with a double free.
Strictly speaking, host resource allocations should have been done in
scsi_host_alloc(). However, the allocations may need information which is
not yet provided by the driver when that function is called. So leave the
allocations where they are but rely on host device's release handler to
free resources.

commit 66a834d092930cf41d809c0e989b13cd6f9ca006 upstream.
After device is initialized via device_initialize(), or its name is set via
dev_set_name(), the device has to be freed via put_device(). Otherwise
device name will be leaked because it is allocated dynamically in
dev_set_name().
Fix the leak by replacing kfree() with put_device(). Since
scsi_host_dev_release() properly handles IDA and kthread removal, remove
special-casing these from the error handling as well.
