Couple of error paths in do_core_test() was returning directly without

If a duplicate attribute is found using kset_find_obj(), a reference
to that attribute is returned which needs to be disposed accordingly
using kobject_put(). Use kobject_put() to dispose the duplicate
attribute in such a case.
As a side note, a very similar bug was fixed in
commit 7295a996fdab ("platform/x86: dell-sysman: Fix reference leak"),
so it seems that the bug was copied from that driver.

The k3_udma_glue_tx_get_irq() function currently returns negative error
codes on error, zero on error and positive values for success. This
complicates life for the callers who need to propagate the error code.
Also GCC will not warn about unsigned comparisons when you check:
if (unsigned_irq <= 0)
All the callers have been fixed now but let's just make this easy going
forward.

In the while loop of vringh_iov_xfer(), `partlen` could be 0 if one of
the `iov` has 0 lenght.
In this case, we should skip the iov and go to the next one.
But calling vringh_kiov_advance() with 0 lenght does not cause the
advancement, since it returns immediately if asked to advance by 0 bytes.
Let's restore the code that was there before commit b8c06ad4d67d
("vringh: implement vringh_kiov_advance()"), avoiding using
vringh_kiov_advance().

blk_mark_disk_dead is the proper interface to shut down a block
device, but it also makes the disk unusable forever.
nbd_clear_sock_ioctl on the other hand wants to shut down the file
system, but allow the block device to be used again when when connected
to another socket. Switch nbd to use disk_force_media_change and
nbd_bdev_reset to go back to a behavior of the old __invalidate_device
call, with the added benefit of incrementing the device generation
as there is no guarantee the old content comes back when the device
is reconnected.

Report the maximum number of IBs that can be pushed with a single
DRM_IOCTL_NOUVEAU_EXEC through DRM_IOCTL_NOUVEAU_GETPARAM.
While the maximum number of IBs per ring might vary between chipsets,
the kernel will make sure that userspace can only push a fraction of the
maximum number of IBs per ring per job, such that we avoid a situation
where there's only a single job occupying the ring, which could
potentially lead to the ring run dry.
Using DRM_IOCTL_NOUVEAU_GETPARAM to report the maximum number of IBs
that can be pushed with a single DRM_IOCTL_NOUVEAU_EXEC implies that
all channels of a given device have the same ring size.

When raid5_get_active_stripe is called with a ctx containing a stripe_head in
its batch_last pointer, it can cause a deadlock if the task sleeps waiting on
another stripe_head to become available. The stripe_head held by batch_last
can be blocking the advancement of other stripe_heads, leading to no
stripe_heads being released so raid5_get_active_stripe waits forever.
Like with the quiesce state handling earlier in the function, batch_last
needs to be released by raid5_get_active_stripe before it waits for another
stripe_head.

The flexible structure (a structure that contains a flexible-array member
at the end) `qed_ll2_tx_packet` is nested within the second layer of
`struct qed_ll2_info`:
struct qed_ll2_tx_packet {
...
/* Flexible Array of bds_set determined by max_bds_per_packet */
struct {
struct core_tx_bd *txq_bd;
dma_addr_t tx_frag;
u16 frag_len;
} bds_set[];
};
struct qed_ll2_tx_queue {
...
struct qed_ll2_tx_packet cur_completing_packet;
};
struct qed_ll2_info {
...
struct qed_ll2_tx_queue tx_queue;
struct qed_ll2_cbs cbs;
};
The problem is that member `cbs` in `struct qed_ll2_info` is placed just
after an object of type `struct qed_ll2_tx_queue`, which is in itself
an implicit flexible structure, which by definition ends in a flexible
array member, in this case `bds_set`. This causes an undefined behavior
bug at run-time when dynamic memory is allocated for `bds_set`, which
could lead to a serious issue if `cbs` in `struct qed_ll2_info` is
overwritten by the contents of `bds_set`. Notice that the type of `cbs`
is a structure full of function pointers (and a cookie :) ):
include/linux/qed/qed_ll2_if.h:
107 typedef
108 void (*qed_ll2_complete_rx_packet_cb)(void *cxt,
109 struct qed_ll2_comp_rx_data *data);
110
111 typedef
112 void (*qed_ll2_release_rx_packet_cb)(void *cxt,
113 u8 connection_handle,
114 void *cookie,
115 dma_addr_t rx_buf_addr,
116 bool b_last_packet);
117
118 typedef
119 void (*qed_ll2_complete_tx_packet_cb)(void *cxt,
120 u8 connection_handle,
121 void *cookie,
122 dma_addr_t first_frag_addr,
123 bool b_last_fragment,
124 bool b_last_packet);
125
126 typedef
127 void (*qed_ll2_release_tx_packet_cb)(void *cxt,
128 u8 connection_handle,
129 void *cookie,
130 dma_addr_t first_frag_addr,
131 bool b_last_fragment, bool b_last_packet);
132
133 typedef
134 void (*qed_ll2_slowpath_cb)(void *cxt, u8 connection_handle,
135 u32 opaque_data_0, u32 opaque_data_1);
136
137 struct qed_ll2_cbs {
138 qed_ll2_complete_rx_packet_cb rx_comp_cb;
139 qed_ll2_release_rx_packet_cb rx_release_cb;
140 qed_ll2_complete_tx_packet_cb tx_comp_cb;
141 qed_ll2_release_tx_packet_cb tx_release_cb;
142 qed_ll2_slowpath_cb slowpath_cb;
143 void *cookie;
144 };
Fix this by moving the declaration of `cbs` to the middle of its
containing structure `qed_ll2_info`, preventing it from being
overwritten by the contents of `bds_set` at run-time.
This bug was introduced in 2017, when `bds_set` was converted to a
one-element array, and started to be used as a Variable Length Object
(VLO) at run-time.

This issue is caused because usbnet_read_cmd() reads less bytes than requested
(zero byte in the reproducer). In this case, 'buf' is not properly filled.
This patch fixes the issue by returning -ENODATA if usbnet_read_cmd() reads
less bytes than requested.

Initialize the structure to 0 so that it's fields won't have random
values. For example fields like rec.traffic_class (as well as
rec.flow_label and rec.sl) is used to generate the user AH through:
cma_iboe_join_multicast
cma_make_mc_event
ib_init_ah_from_mcmember
And a random traffic_class causes a random IP DSCP in RoCEv2.

The reason is the mentioned commit changed tegra_vi_graph_find_entity() to
search for an entity in the done notifier list:
> @@ -1464,7 +1464,7 @@ tegra_vi_graph_find_entity(struct tegra_vi_channel *chan,
> struct tegra_vi_graph_entity *entity;
> struct v4l2_async_connection *asd;
>
> - list_for_each_entry(asd, &chan->notifier.asc_list, asc_entry) {

> entity = to_tegra_vi_graph_entity(asd);
> if (entity->asd.match.fwnode == fwnode)
> return entity;
This is not always correct, being tegra_vi_graph_find_entity() called in
three locations, in this order:
1. tegra_vi_graph_parse_one() -- called while probing
2. tegra_vi_graph_notify_bound() -- the .bound notifier op
3. tegra_vi_graph_build() -- called in the .complete notifier op
Locations 1 and 2 are called before moving the entity from waiting_list to
done_list, thus they won't find what they are looking for in
done_list. Location 3 happens afterwards and thus it is not broken, however
it means tegra_vi_graph_find_entity() should not search in the same list
every time.
The error appears at step 1: tegra_vi_graph_parse_one() iterates
recursively until it finds the entity already notified, which now never
happens.
Fix by passing the specific notifier list pointer to
tegra_vi_graph_find_entity() instead of the channel, so each caller can
search in whatever list is correct.
Also improve the tegra_vi_graph_find_entity() comment.

The current Kconfig symbol dependencies allow having the following Kconfig
symbol values
CONFIG_IPU_BRIDGE=m
CONFIG_VIDEO_IPU3_CIO2=y
CONFIG_CIO2_BRIDGE=n
This does not work as the IPU bridge API is conditional to
IS_ENABLED(CONFIG_IPU_BRIDGE). Fix this by changing the dependencies so
that CONFIG_IPU_BRIDGE can be separately selected.
The CONFIG_CIO2_BRIDGE symbol becomes redundant as a result and is
removed.

In the pathological case of building sky2 with 16k PAGE_SIZE, the
frag_addr[] array would never be used, so the original code was correct
that size should be 0. But the compiler now gets upset with 0 size arrays
in places where it hasn't eliminated the code that might access such an
array (it can't figure out that in this case an rx skb with fragments
would never be created). To keep the compiler happy, make sure there is
at least 1 frag_addr in struct rx_ring_info:

Since commit 23d775f12dcd ("net: dsa: mv88e6xxx: Wait for EEPROM done
before HW reset") the following error is seen on a imx8mn board with
a 88E6320 switch:
mv88e6085 30be0000.ethernet-1:00: Timeout waiting for EEPROM done
This board does not have an EEPROM attached to the switch though.
This problem is well explained by Andrew Lunn:
"If there is an EEPROM, and the EEPROM contains a lot of data, it could
be that when we perform a hardware reset towards the end of probe, it
interrupts an I2C bus transaction, leaving the I2C bus in a bad state,
and future reads of the EEPROM do not work.
The work around for this was to poll the EEInt status and wait for it
to go true before performing the hardware reset.
However, we have discovered that for some boards which do not have an
EEPROM, EEInt never indicates complete. As a result,
mv88e6xxx_g1_wait_eeprom_done() spins for a second and then prints a
warning.
We probably need a different solution than calling
mv88e6xxx_g1_wait_eeprom_done(). The datasheet for 6352 documents the
EEPROM Command register:
bit 15 is:
EEPROM Unit Busy. This bit must be set to a one to start an EEPROM
operation (see EEOp below). Only one EEPROM operation can be
executing at one time so this bit must be zero before setting it to
a one. When the requested EEPROM operation completes this bit will
automatically be cleared to a zero. The transition of this bit from
a one to a zero can be used to generate an interrupt (the EEInt in
Global 1, offset 0x00).
and more interesting is bit 11:
Register Loader Running. This bit is set to one whenever the
register loader is busy executing instructions contained in the
EEPROM."
Change to using mv88e6xxx_g2_eeprom_wait() to fix the timeout error
when the EEPROM chip is not present.

Mark Blakeney reported that when suspending system with a Thunderbolt
dock connected and then unplugging the dock before resume (which is
pretty normal flow with laptops), resuming takes long time.
What happens is that the PCIe link from the root port to the PCIe switch
inside the Thunderbolt device does not train (as expected, the link is
unplugged):
pcieport 0000:00:07.2: restoring config space at offset 0x24 (was 0x3bf12001, writing 0x3bf12001)
pcieport 0000:00:07.0: waiting 100 ms for downstream link
pcieport 0000:01:00.0: not ready 1023ms after resume; giving up
However, at this point we still try to resume the devices below that
unplugged link:
pcieport 0000:01:00.0: Unable to change power state from D3cold to D0, device inaccessible
...
pcieport 0000:01:00.0: restoring config space at offset 0x38 (was 0xffffffff, writing 0x0)
...
pcieport 0000:02:02.0: waiting 100 ms for downstream link, after activation
And this is the link from PCIe switch downstream port to the xHCI on the
dock:
xhci_hcd 0000:03:00.0: not ready 65535ms after resume; giving up
xhci_hcd 0000:03:00.0: Unable to change power state from D3cold to D0, device inaccessible
xhci_hcd 0000:03:00.0: restoring config space at offset 0x3c (was 0xffffffff, writing 0x1ff)
This ends up slowing down the resume time considerably. For this reason
mark these devices as disconnected if the link above them did not train
properly.

of_pci_prop_intr_map() uses uninitialized addr_sz[] values if
of_irq_parse_raw() fails, which leads to intermittent crashes.
Clear addr_sz[] before use so we never use uninitialized elements.
If no valid IRQs are parsed, don't bother adding the interrupt-map
property.

PARF_SLV_ADDR_SPACE_SIZE_2_3_3 is used by qcom_pcie_post_init_2_3_3().
This PCIe slave address space size register offset is 0x358 but was
incorrectly changed to 0x16c by 39171b33f652 ("PCI: qcom: Remove PCIE20_
prefix from register definitions").
This prevented access to slave address space registers like iATU, etc.,
so the IPQ8074 PCIe controller was not enumerated.
Revert back to the correct 0x358 offset and remove the unused
PARF_SLV_ADDR_SPACE_SIZE_2_3_3.

Pull ATA fixes from Damien Le Moal:
"A larger than usual set of fixes for 6.6-rc4 due to the unexpected
number of fixes needed to address ATA disks suspend/resume issues.
In more detail:
- Add missing additionalProperties on child nodes to the pata-common
DT bindings (Rob)
- Fix handling of the REPORT SUPPORTED OPERATION CODES command to
ignore reserved bits (Niklas)
- Increase port multiplier soft reset timeout to accomodate slow
devices and avoid issues on wakeup (Matthias)
- A couple of minor code fixes to avoid compilation warnings in
libata-core and libata-eh (me)
- Many patches from me to address suspend/resume issues, and in
particular a potential deadlock on resume due to the SCSI disk
driver resume operation not being synchronized with libata EH port
resume handling.
This is addressed by changing the scsi disk driver disk start/stop
control to allow libata to execute disk suspend (spin down) and
resume (spin up) on its own during system suspend/resume. Runtime
suspend/resume control remains with the SCSI disk driver.
Other fixes include:
- Fix libata power management request issuing to avoid races
- Establish a link between ATA ports and SCSI devices to order PM
operations
- Fix device removal to avoid issues with driver rmmod removal
- Fix synchronization of libata device rescan and SCSI disk resume
operation
- Remove libsas PM operations as suspend/resume is handled
directly by the sas controller resume
- Fix the SCSI disk driver to not issue commands to suspended
disks, thus avoiding potential system lock-up on resume"
