commit bb0829a741792b56c908d7745bc0b2b540293bcc upstream.
Currently the driver spams the kernel log on unsupported ioctls which is
unnecessary as the ioctl returns -ENOIOCTLCMD to indicate this anyway.
I suspect this was originally for debugging purposes but it really is not
required so remove it.

Subject: media: usbtv: prevent double free in error case
From: Oliver Neukum <oneukum(a)suse.com>
commit 50e7044535537b2a54c7ab798cd34c7f6d900bd2 upstream.
Quoting the original report:
It looks like there is a double-free vulnerability in Linux usbtv driver
on an error path of usbtv_probe function. When audio registration fails,
usbtv_video_free function ends up freeing usbtv data structure, which
gets freed the second time under usbtv_video_fail label.
usbtv_audio_fail:
usbtv_video_free(usbtv); =>
v4l2_device_put(&usbtv->v4l2_dev);
=> v4l2_device_put
=> kref_put
=> v4l2_device_release
=> usbtv_release (CALLBACK)
=> kfree(usbtv) (1st time)
usbtv_video_fail:
usb_set_intfdata(intf, NULL);
usb_put_dev(usbtv->udev);
kfree(usbtv); (2nd time)
So, as we have refcounting, use it

The RSA private key for the first form should have
version, prime1, prime2, exponent1, exponent2, coefficient
values 0.
With non-zero values for prime1,2, exponent 1,2 and coefficient
the Intel QAT driver will assume that values are provided for the
private key second form. This will result in signature verification
failures for modules where QAT device is present and the modules
are signed with rsa,sha256.

With ecb-cast5-avx, if a 128+ byte scatterlist element followed a
shorter one, then the algorithm accidentally encrypted/decrypted only 8
bytes instead of the expected 128 bytes. Fix it by setting the

Subject: crypto: ccp - return an actual key size from RSA max_size callback
From: Maciej S. Szmigiero <mail(a)maciej.szmigiero.name>
commit 0a9eb80e643064266868bd2fb2cd608e669309b0 upstream.
rsa-pkcs1pad uses a value returned from a RSA implementation max_size
callback as a size of an input buffer passed to the RSA implementation for
encrypt and sign operations.
CCP RSA implementation uses a hardware input buffer which size depends only
on the current RSA key length, so it should return this key length in
the max_size callback, too.
This also matches what the kernel software RSA implementation does.
Previously, the value returned from this callback was always the maximum
RSA key size the CCP hardware supports.
This resulted in this huge buffer being passed by rsa-pkcs1pad to CCP even
for smaller key sizes and then in a buffer overflow when ccp_run_rsa_cmd()
tried to copy this large input buffer into a RSA key length-sized hardware
input buffer.

Subject: crypto: inside-secure - fix clock management
From: Gregory CLEMENT <gregory.clement(a)bootlin.com>
commit f962eb46e7a9b98a58d2483f5eb216e738fec732 upstream.
In this driver the clock is got but never put when the driver is removed
or if there is an error in the probe.
Using the managed version of clk_get() allows to let the kernel take care
of it.
Fixes: 1b44c5a60c13 ("crypto: inside-secure - add SafeXcel EIP197 crypto
engine driver")
