ef0162298a RDMA/cxgb4: fix accept failure due to increased cpl_t5_pass_accept_rpl size
Commit 'c2ed5611afd7' has increased the cpl_t5_pass_accept_rpl{} structure
size by 8B to avoid roundup. cpl_t5_pass_accept_rpl{} is a HW specific
structure and increasing its size will lead to unwanted adapter errors.
Current commit reverts the cpl_t5_pass_accept_rpl{} back to its original
and allocates zeroed skb buffer there by avoiding the memset for iss field.
Reorder code to minimize chip type checks.

d6d142cb7f IB/iser: Fix login with authentication
The iSER Initiator uses two types of receive buffers:

  - one big login buffer posted by iser_post_recvl();
  - several small message buffers posted by iser_post_recvm().

The login buffer is used at the login phase and full feature phase in
the discovery session. It may take a few requests and responses to
complete the login phase. The message buffers are only used in the
normal operational session at the full feature phase.

After the commit referred in the fixes line, the login operation fails
if the authentication is enabled. That happens because the Initiator
posts a small receive buffer after the first response from Target. So,
the next send operation fails because Target's second response does not
fit into the small receive buffer.

This commit adds additional checks to prevent posting small receive
buffers until the full feature phase.

e6190dd003 ublk_drv: do not add a re-issued request aborted previously to ioucmd's task_work
In ublk_queue_rq(), Assume current request is a re-issued request aborted
previously in monitor_work because the ubq_daemon(ioucmd's task) is
PF_EXITING. For this request, we cannot call
io_uring_cmd_complete_in_task() anymore because at that moment io_uring
context may be freed in case that no inflight ioucmd exists. Otherwise,
we may cause null-deref in ctx->fallback_work.

Add a check on UBLK_IO_FLAG_ABORTED to prevent the above situation. This
check is safe and makes sense.

Note: monitor_work sets UBLK_IO_FLAG_ABORTED and ends this request
(releasing the tag). Then the request is restarted(allocating the tag)
and we are here. Since releasing/allocating a tag implies smp_mb(),
finding UBLK_IO_FLAG_ABORTED guarantees that here is a re-issued request
aborted previously.

2e9ca760c2 virtio_net: Revert "virtio_net: set the default max ring size by find_vqs()"
This reverts commit 762faee5a2.

This has been reported to trip up guests on GCP (Google Cloud).
The reason is that virtio_find_vqs_ctx_size is broken on legacy
devices. We can in theory fix virtio_find_vqs_ctx_size but
in fact the patch itself has several other issues:

- It treats unknown speed as < 10G
- It leaves userspace no way to find out the ring size set by hypervisor
- It tests speed when link is down
- It ignores the virtio spec advice:
        Both \field{speed} and \field{duplex} can change, thus the driver
        is expected to re-read these values after receiving a
        configuration change notification.
- It is not clear the performance impact has been tested properly

Revert the patch for now.

Remove unnecessary generic_fillattr to fix wrong
AllocationSize of SMB2_CREATE response, And
Move the call of ksmbd_vfs_getattr above the place

This patch fixes wrong AllocationSize of SMB2_CREATE
response. Because ext4 updates inode->i_blocks only
when disk space is allocated, generic_fillattr does
not set stat.blocks properly for delayed allocation.
But ext4 returns the blocks that include the delayed
allocation blocks when getattr is called.

The issue can be reproduced with commands below:

touch ${FILENAME}
xfs_io -c "pwrite -S 0xAB 0 40k" ${FILENAME}
xfs_io -c "stat" ${FILENAME}

40KB are written, but the count of blocks is 8.

The only valid CPU that can then be returned, if any, will be the first
one set in the provided 'mask'.

For NR_CPUS == 1, include/linux/cpumask.h now provides an inline
definition of cpumask_next_wrap(), which will conflict with the one

Since f3a2181e16 ("netfilter: nf_tables: Support for sets with
multiple ranged fields"), it possible to combine intervals and
concatenations. Later on, ef516e8625 ("netfilter: nf_tables:
reintroduce the NFT_SET_CONCAT flag") provides the NFT_SET_CONCAT flag
for userspace to report that the set stores a concatenation.

Make sure NFT_SET_CONCAT is set on if field_count is specified for
consistency. Otherwise, if NFT_SET_CONCAT is specified with no
field_count, bail out with EINVAL.

fd0c153daa nios2: add force_successful_syscall_return()
If we use the ancient SysV syscall ABI, we'd better have tell the
kernel how to claim that a negative return value is a success.
Use ->orig_r2 for that - it's inaccessible via ptrace, so it's
a fair game for changes and it's normally[*] non-negative on return
from syscall.  Set to -1; syscall is not going to be restart-worthy
by definition, so we won't interfere with that use either.

[*] the only exception is rt_sigreturn(), where we skip the entire
messing with r1/r2 anyway.

0fef40be5d s390/ap: fix crash on older machines based on QCI info missing
On older z series machines (z12 and older) there is no QCI info
available. The AP code took care of this and the AP bus scan then
switched to simple probing via TAPQ.

With commit
283915850a ("s390/ap: notify drivers on config changed and scan complete callbacks")
some code was introduced which silently assumed that the QCI info is
always available. However, with KVM simulating an older machine (z12)
the result was a kernel crash. Funnily the same crash does not happen
on LPAR - maybe because NULL is a valid pointer and reading some data
from address 0 also works fine.

This fix now improves the code to be aware that the QCI instruction
may not be available on older machines and thus the two pointers to
QCI info structs may simple be NULL.

However, on a machine not providing the QCI info the two callbacks to
the zcrypt device drivers on_config_changed() and on_scan_complete()
provide parameters which are pointers to a QCI info struct.
These both callbacks are NOT served if there is no QCI info available.
The only consumer of these callbacks is the vfio device driver. This
driver only supports CEX4 and higher. All physical machines which are
able to provide CEX4 cards have QCI support available. So there is
no sense in for example fill the QCI info struct by hand with looping
over cards and queues and TAPQ each APQN.

to the data complete interrupt will be reserved for the next command.
If the next command with data transfer after cqe off/disable, we process
the CMD ready interrupt and trigger DMA start for data, but the data
complete interrupt is already exists, then SW assume that the data transfer
is complete, SW will trigger DMA stop, but the data may not be transmitted
yet or is transmitting, so we may encounter the following error:

====================
mlxsw: Fixes for PTP support

This set fixes several issues in mlxsw PTP code.

- Patch #1 fixes compilation warnings.

- Patch #2 adjusts the order of operation during cleanup, thereby
  closing the window after PTP state was already cleaned in the ASIC
  for the given port, but before the port is removed, when the user
  could still in theory make changes to the configuration.

- Patch #3 protects the PTP configuration with a custom mutex, instead
  of relying on RTNL, which is not held in all access paths.

- Patch #4 forbids enablement of PTP only in RX or only in TX. The
  driver implicitly assumed this would be the case, but neglected to
  sanitize the configuration.

e01885c31b mlxsw: spectrum_ptp: Forbid PTP enablement only in RX or in TX
Currently mlxsw driver configures one global PTP configuration for all
ports. The reason is that the switch behaves like a transparent clock
between CPU port and front-panel ports. When time stamp is enabled in
any port, the hardware is configured to update the correction field. The
fact that the configuration of CPU port affects all the ports, makes the
correction field update to be global for all ports. Otherwise, user will
see odd values in the correction field, as the switch will update the
correction field in the CPU port, but not in all the front-panel ports.

The CPU port is relevant in both RX and TX, so to avoid problematic
configuration, forbid PTP enablement only in one direction, i.e., only in
RX or TX.

Without the change:
$ hwstamp_ctl -i swp1 -r 12 -t 0
current settings:
tx_type 0
rx_filter 0
new settings:
tx_type 0
rx_filter 2
$ echo $?
0

With the change:
$ hwstamp_ctl -i swp1 -r 12 -t 0
current settings:
tx_type 1
