A number of new laptops have been delivered with only a single antenna.
In principle, this is OK; however, a problem arises when the on-board
EEPROM is programmed to use the other antenna connection. The option
of opening the computer and moving the connector is not always possible
as it will void the warranty in some cases. In addition, this solution
breaks the Windows driver when the box dual boots Linux and Windows.
A fix involving a new module parameter has been developed. This commit
adds the new parameter and implements the changes needed for the driver.

intel_update_max_cdclk() doesn't have a switch case for Broxton, so
dev_priv->max_cdclk_freq gets set to whatever clock frequency we're
currently running at (e.g., 144 MHz) rather than the true maximum. This
causes our max dotclock to also be set too low and in turn leads mode
verification to reject perfectly valid modes while loading EDID firmware
blobs.

This VDMA is a soft ip, which can be programmed to support
32 bit addressing or greater than 32 bit addressing.
When the VDMA ip is configured for 32 bit address space
the buffer address is specified by a single register
(0x5C for MM2S and 0xAC for S2MM channel).
When the VDMA core is configured for an address space greater
than 32 then each buffer address is specified by a combination of
two registers.
The first register specifies the LSB 32 bits of address,
while the next register specifies the MSB 32 bits of address.
For example, 5Ch will specify the LSB 32 bits while 60h will
specify the MSB 32 bits of the first start address.
So we need to program two registers at a time.
This patch adds the 64 bit addressing support to the vdma driver.

Generalise system_verify_data() to provide access to internal content
through a callback. This allows all the PKCS#7 stuff to be hidden inside
this function and removed from the PE file parser and the PKCS#7 test key.
If external content is not required, NULL should be passed as data to the
function. If the callback is not required, that can be set to NULL.
The function is now called verify_pkcs7_signature() to contrast with
verify_pefile_signature() and the definitions of both have been moved into
linux/verification.h along with the key_being_used_for enum.

There's a bug in the code determining whether a certificate is self-signed
or not: if they have neither AKID nor SKID then we just assume that the
cert is self-signed, which may not be true.
Fix this by checking that the raw subject name matches the raw issuer name
and that the public key algorithm for the key and signature are both the
same in addition to requiring that the AKID bits match.
Signed-off-by: David Howells <dhowells@redhat.com>
Extract the signature digest for an X.509 certificate earlier, at the end
of x509_cert_parse() rather than leaving it to the callers thereof since it
has to be called anyway.
Further, immediately after that, check the signature on self-signed
certificates, also rather in the callers of x509_cert_parse().
We note in the x509_certificate struct the following bits of information:
(1) Whether the signature is self-signed (even if we can't check the
signature due to missing crypto).
(2) Whether the key held in the certificate needs unsupported crypto to be
used. We may get a PKCS#7 message with X.509 certs that we can't make
use of - we just ignore them and give ENOPKG at the end it we couldn't
verify anything if at least one of these unusable certs are in the
chain of trust.
(3) Whether the signature held in the certificate needs unsupported crypto
to be checked. We can still use the key held in this certificate,
even if we can't check the signature on it - if it is held in the
system trusted keyring, for instance. We just can't add it to a ring
of trusted keys or follow it further up the chain of trust.
Making these checks earlier allows x509_check_signature() to be removed and
replaced with direct calls to public_key_verify_signature().
Signed-off-by: David Howells <dhowells@redhat.com>
Point to the public_key_signature struct from the pkcs7_signed_info struct
rather than embedding it. This makes the code consistent with the X.509
signature handling and makes it possible to have a common cleanup function.

memory with the crypto layer metadata.

gcc finds that the i40iw_make_cm_node() function in the recently added
i40iw driver uses an uninitilized variable as an index into an array
if CONFIG_IPV6 is disabled and the driver uses IPv6 mode:
drivers/infiniband/hw/i40iw/i40iw_cm.c: In function 'i40iw_make_cm_node':
drivers/infiniband/hw/i40iw/i40iw_cm.c:2206:52: error: 'arpindex' may be used uninitialized in this function [-Werror=maybe-uninitialized]
ether_addr_copy(cm_node->rem_mac, iwdev->arp_table[arpindex].mac_addr);
As far as I can tell, this code path can not be used because the ipv4
variable is always set with CONFIG_IPV6 is disabled, but it's better
to be sure and prevent the undefined behavior, as well as shut up
that warning in a proper way.
This adds an 'else' clause for the case we get the warning about,
causing the function to return an error in a controlled way.

I'm also converting the existing #ifdef into a more readable

Currently drivers are limited to 19 slots for cyclic transfers.
However, if the DMA burst size is the same as the period size,
the period size can be changed to the full buffer size and
intermediate interrupts activated. Since intermediate interrupts
will trigger for each burst and the burst size is the same as
the period size, the driver will get interrupts each period as
expected. This has the benefit of allowing the functionality of
many more slots, but only uses 2 slots.
This workaround is only active if more than 19 slots are needed
and the burst size matches the period size.
