[ Upstream commit 85db6352fc8a158a893151baa1716463d34a20d0 ]

The find_next_netdev_feature() macro gets the "remaining length", not bit index.
Passing "bit - 1" for the following iteration is wrong as it skips the adjacent bit. Pass "bit" instead.

The metadata dst is leaked when ip_route_input_mc() updates the dst for the skb. Commit f38a9eb1f77b ("dst: Metadata destinations") correctly handled dropping the dst in ip_route_input_slow() but missed the multicast case which is handled by ip_route_input_mc(). Drop the dst in ip_route_input_mc() avoiding the leak.

[ Upstream commit d5076fe4049cadef1f040eda4aaa001bb5424225 ]

netlink_recvmsg() does not need to change transport header.

If transport header was needed, it should have been reset by the producer (netlink_dump()), not the consumer(s).

The following trace probably happened when multiple threads were using MSG_PEEK.

This is needed since it might use (and pass out) pointers to e.g. keys protected by RCU. Can't really happen here as the frames aren't encrypted, but we need to still adhere to the rules.

[ Upstream commit 1fa89ffbc04545b7582518e57f4b63e2a062870f ]

In the NIC ->probe() callback, ->mtd_probe() callback is called. If NIC has 2 ports, ->probe() is called twice and ->mtd_probe() too. In the ->mtd_probe(), which is efx_ef10_mtd_probe() it allocates and initializes mtd partiion.
But mtd partition for sfc is shared data.
So that allocated mtd partition data from last called efx_ef10_mtd_probe() will not be used.
Therefore it must be freed.
But it doesn't free a not used mtd partition data in efx_ef10_mtd_probe().

The max98090 driver has a custom put function for some controls which can only be updated in certain circumstances which makes no effort to validate that input is suitable for the control, allowing out of spec values to be written to the hardware and presented to userspace. Fix this by returning an error when invalid values are written.

[ Upstream commit aa22125c57f9e577f0a667e4fa07fc3fa8ca1e60 ]

Check that values written via snd_soc_put_volsw_range() are within the range advertised by the control, ensuring that we don't write out of spec values to the hardware.

commit 01e01f5c89773c600a9f0b32c888de0146066c3a upstream.

cdc-wdm tracks whether a response reading request is in-progress and blocks the next request from being sent until the previous request is completed. As soon as last user closes the cdc-wdm device file, the driver cancels any ongoing requests, resets the pending response counter, but leaves the response reading in-progress flag (WDM_RESPONDING) untouched.

So if the user closes the device file during the response receive request is being performed, no more data will be obtained from the modem. The request will be cancelled, effectively preventing the WDM_RESPONDING flag from being reseted. Keeping the flag set will prevent a new response receive request from being sent, permanently blocking the read path. The read path will staying blocked until the module will be reloaded or till the modem will be re-attached.

This stuck has been observed with a Huawei E3372 modem attached to an OpenWrt router and using the comgt utility to set up a network connection.

Fix this issue by clearing the WDM_RESPONDING flag on the device file close.

Without this fix, the device reading stuck can be easily reproduced in a few connection establishing attempts. With this fix, a load test for modem connection re-establishing worked for several hours without any issues.

commit 714adff9a6271b5f1664b04c944b598141ebfe73 upstream.

The L610 modem has 3 USB configurations that are configurable via the AT command AT+GTUSBMODE={31,32,33} which make the modem enumerate with the following interfaces, respectively:

31: Modem + NV + MOS + Diag + LOG + AT + AT 32: ECM + Modem + NV + MOS + Diag + LOG + AT + AT 33: RNDIS + Modem + NV + MOS + Diag + LOG + AT + AT

commit 07989eb981d862f7f2be68d233d753f2e7ccc119 upstream.

The MA510 modem has 3 USB configurations that are configurable via the AT command AT+GTUSBMODE={30,31,32} which make the modem enumerate with the following interfaces, respectively:

30: Diag + QDSS + Modem + RMNET
31: Diag + Modem + AT + ECM
32: Modem + AT + ECM

The first configuration (30) reuses u-blox R410M's VID/PID with identical interface configuration.

A detailed description of the USB configuration for each mode follows:

commit e1a7ac6f3ba6e157adcd0ca94d92a401f1943f56 upstream.

When ping_group_range is updated, 'ping' uses the DGRAM ICMP socket, instead of an IP raw socket. In this case, 'ping' is unable to bind its socket to a local address owned by a vrflite.

Before the patch:

$ sysctl -w net.ipv4.ping_group_range='0  2147483647'
$ ip link add blue type vrf table 10
$ ip link add foo type dummy
$ ip link set foo master blue
$ ip link set foo up
$ ip addr add 192.168.1.1/24 dev foo
$ ip addr add 2001::1/64 dev foo
$ ip vrf exec blue ping -c1 -I 192.168.1.1 192.168.1.2
ping: bind: Cannot assign requested address
$ ip vrf exec blue ping6 -c1 -I 2001::1 2001::2
ping6: bind icmp socket: Cannot assign requested address

commit 447ee1516f19f534a228dda237eddb202f23e163 upstream.

It will cause null-ptr-deref when using 'res', if platform_get_resource() returns NULL, so move using 'res' after devm_ioremap_resource() that will check it to avoid null-ptr-deref.
And use devm_platform_get_and_ioremap_resource() to simplify code.
