commit b2ba9225e0313b1de631a44b7b48c109032bffec upstream.

commit e03327122e2c ("pci_endpoint_test: Add 2 ioctl commands")
uses module parameter 'irqtype' in pci_endpoint_test_set_irq()
to check if IRQ vectors of a particular type (MSI or MSI-X or
LEGACY) is already allocated. However with multi-function devices,
'irqtype' will not correctly reflect the IRQ type of the PCI device.

Fix it here by adding 'irqtype' for each PCI device to show the
IRQ type of a particular PCI device.

commit 6b443e5c80b67a7b8a85b33d052d655ef9064e90 upstream.

Adding more than 10 pci-endpoint-test devices results in
"kobject_add_internal failed for pci-endpoint-test.1 with -EEXIST, don't
try to register things with the same name in the same directory". This
is because commit 2c156ac71c6b ("misc: Add host side PCI driver for PCI
test function device") limited the length of the "name" to 20 characters.
Change the length of the name to 24 in order to support upto 10000
pci-endpoint-test devices.

<content type='text'>
The at24 driver attempts to read a byte from the device to validate that
it's actually present, and if not, disables the vcc regulator and
returns -ENODEV. However, between the read and the error handling path,
pm_runtime_idle() is called and invokes the driver's suspend callback,
which also disables the vcc regulator. This leads to an underflow of the
regulator enable count if the EEPROM is not present.

Move the pm_runtime_suspend() call to be after the error handling path
to resolve this.

<title>altera-stapl: altera_get_note: prevent write beyond end of 'key'</title>

altera_get_note is called from altera_init, where key is kzalloc(33).

When the allocation functions are annotated to allow the compiler to see
the sizes of objects, and with FORTIFY_SOURCE, we see:

In file included from drivers/misc/altera-stapl/altera.c:14:0:
In function ‘strlcpy’,
    inlined from ‘altera_init’ at drivers/misc/altera-stapl/altera.c:2189:5:
include/linux/string.h:378:4: error: call to ‘__write_overflow’ declared with attribute error: detected write beyond size of object passed as 1st parameter
    __write_overflow();
    ^~~~~~~~~~~~~~~~~~

That refers to this code in altera_get_note:

    if (key != NULL)
            strlcpy(key, &amp;p[note_strings +
                            get_unaligned_be32(
                            &amp;p[note_table + (8 * i)])],
                    length);

The error triggers because the length of 'key' is 33, but the copy
uses length supplied as the 'length' parameter, which is always
256. Split the size parameter into key_len and val_len, and use the
appropriate length depending on what is being copied.

Detected by compiler error, only compile-tested.

During device memory memset, the driver allocates and use a CB (command
buffer). To reuse existing code, it keeps a pointer to the CB in two
variables, user_cb and patched_cb. Therefore, there is no need to "put"
both the user_cb and patched_cb, as it will cause an underflow of the
refcnt of the CB.

During hard reset we must not write to the device.
Hence avoid halting CoreSight during user context close if it is done
during hard reset.
In addition, we must not re-enable clock gating afterwards as it was
deliberately disabled in the beginning of the hard reset flow.

The driver must halt the engines before doing hard-reset, otherwise the
device can go into undefined state. There is a place where the driver
didn't do that and this patch fixes it.
