The direction of the pipe argument must match the request-type direction
bit or control requests may fail depending on the host-controller-driver
implementation.
Fix the tiocmset and rfkill requests which erroneously used
usb_rcvctrlpipe().

Verify some fields of the USB descriptor to make sure the driver
could be used by the device.
Besides, remove the check of endpoint number in rtl8152_probe().
usb_find_common_endpoints() includes it.

If Qdisc_ops->init() is failed, Qdisc_ops->reset() would be called.
When dsmark_init(Qdisc_ops->init()) is failed, it possibly doesn't
initialize dsmark_qdisc_data->q. But dsmark_reset(Qdisc_ops->reset())
uses dsmark_qdisc_data->q pointer wihtout any null checking.
So, panic would occur.
Test commands:
sysctl net.core.default_qdisc=dsmark -w
ip link add dummy0 type dummy
ip link add vw0 link dummy0 type virt_wifi
ip link set vw0 up
Splat looks like:

The opening comment mark '/**' is used for highlighting the beginning of
kernel-doc comments.
The header for drivers/nfc/nfcmrvl follows this syntax, but the content
inside does not comply with kernel-doc.
This line was probably not meant for kernel-doc parsing, but is parsed
due to the presence of kernel-doc like comment syntax(i.e, '/**'), which
causes unexpected warnings from kernel-doc.
For e.g., running scripts/kernel-doc -none on drivers/nfc/nfcmrvl/spi.c
causes warning:
warning: expecting prototype for Marvell NFC(). Prototype was for SPI_WAIT_HANDSHAKE() instead
Provide a simple fix by replacing such occurrences with general comment
format, i.e. '/*', to prevent kernel-doc from parsing it.

PCR_MATRIX field was set to all 1's when VLAN filtering is enabled, but
was not reset when it is disabled, which may cause traffic leaks:
ip link add br0 type bridge vlan_filtering 1
ip link add br1 type bridge vlan_filtering 1
ip link set swp0 master br0
ip link set swp1 master br1
ip link set br0 type bridge vlan_filtering 0
ip link set br1 type bridge vlan_filtering 0
# traffic in br0 and br1 will start leaking to each other
As port_bridge_{add,del} have set up PCR_MATRIX properly, remove the
PCR_MATRIX write from mt7530_port_set_vlan_aware.

the patch that fixed an endless loop in_fq_pie_init() was not considering
that 65535 is a valid class id. The correct bugfix for this infinite loop
is to change 'idx' to become an u32, like Colin proposed in the past [1].
Fix this as follows:
- restore 65536 as maximum possible values of 'flows_cnt'
- use u32 'idx' when iterating on 'q->flows'
- fix the TDC selftest
This reverts commit bb2f930d6dd708469a587dc9ed1efe1ef969c0bf.

If runtime power menagement is enabled, the gigabit ethernet PLL would

would hang up if we try to access GEMGXL control registers.
We can't put runtime_pm_get/runtime_pm_put/ there due to the issue of
sleep inside atomic section (7fa2955ff70ce453 ("sh_eth: Fix sleeping

The MT7628/88 SoC(s) have other (limited) packet counter registers than
currently supported in the mtk_eth_soc driver. This patch adds support
for reading these registers, so that the packet statistics are correctly

Additionally the defines for the non-MT7628 variant packet counter
registers are added and used in this patch instead of using hard coded
values.

It was not freed because the flag irqs_hooked was not set during

When TCP is used as transport and a program on the
system connects to RDS port 16385, connection is
accepted but denied per the rules of RDS. However,
RDS connections object is left in the list. Next
loopback connection will select that connection
object as it is at the head of list. The connection
attempt will hang as the connection object is set
to connect over TCP which is not allowed
The issue can be reproduced easily, use rds-ping
to ping a local IP address. After that use any
program like ncat to connect to the same IP
address and port 16385. This will hang so ctrl-c out.
Now try rds-ping, it will hang.
To fix the issue this patch adds checks to disallow
the connection object creation and destroys the
connection object.

When calling the 'ql_sem_spinlock', the driver has already acquired the

This bug can be fixed by using 'mdelay' instead of 'ssleep'.

The opening comment mark '/**' is used for highlighting the beginning of
kernel-doc comments.
The header for drivers/net/ethernet/microchip/encx24j600 files follows
this syntax, but the content inside does not comply with kernel-doc.
This line was probably not meant for kernel-doc parsing, but is parsed
due to the presence of kernel-doc like comment syntax(i.e, '/**'), which
causes unexpected warning from kernel-doc.
For e.g., running scripts/kernel-doc -none
drivers/net/ethernet/microchip/encx24j600_hw.h emits:
warning: expecting prototype for h(). Prototype was for _ENCX24J600_HW_H() instead
Provide a simple fix by replacing such occurrences with general comment
format, i.e. '/*', to prevent kernel-doc from parsing it.

Check that the MTU value requested by the VF is in the supported
range of MTUs before attempting to set the VF large packet enable,
otherwise reject the request. This also avoids unnecessary
register updates in the case of the 82599 controller.
