When ioremap_nocache fails, the lack of error-handling code may cause

This patch adds error-handling code after calling ioremap_nocache.

Since commit 312d3e56119a ("[SCSI] libsas: remove ata_port.lock management
duties from lldds") the sas_ata_qc_issue() function unlocks the
ata_port.lock and disables interrupts before doing so. That lock is always
taken with disabled interrupts so at this point, the interrupts are already
disabled. There is no need to disable the interrupts before the unlock
operation because they are already disabled. Restoring the interrupt state
later does not change anything because they were disabled and remain
disabled. Therefore remove the operations which do not change the
behaviour.

Currently the driver spends much time allocating and freeing the slot DMA
buffer for command delivery/completion. To boost the performance,
pre-allocate the buffers for all IPTT. The downside of this approach is
that we are reallocating all buffer memory upfront, so hog memory which we
may not need.
However, the current method - DMA buffer pool - also caches all buffers and
does not free them until the pool is destroyed, so is not exactly efficient
either.
On top of this, since the slot DMA buffer is slightly bigger than a 4K
page, we need to allocate 2x4K pages per buffer (for 4K page kernel), which
is quite wasteful. For 64K page size this is not such an issue.
So, for the 4K page case, in order to make memory usage more efficient,
pre-allocating larger blocks of DMA memory for the buffers can be more
efficient.
To make DMA memory usage most efficient, we would choose a single
contiguous DMA memory block, but this could use up all the DMA memory in
the system (when CMA enabled and no IOMMU), or we may just not be able to
allocate a DMA buffer large enough when no CMA or IOMMU.
To decide the block size we use the LCM (least common multiple) of the
buffer size and the page size. We roundup(64) to ensure the LCM is not too
large, even though a little memory may be wasted per block.
So, with this, the total memory requirement is about is about 17MB for 4096
max IPTT.
Previously (for 4K pages case), it would be 32MB (for all slots
allocated).
With this change, the relative increase of IOPS for bs=4K read when
PAGE_SIZE=4K and PAGE_SIZE=64K is as follows:
IODEPTH 4K PAGE_SIZE 64K PAGE_SIZE
32 56% 47%
64 53% 44%
128 64% 43%

In host reset, we use TMF or soft-reset to re-init device, and if success,
we will release all LLDD resources of this device. If the init fails -
maybe because the device was removed or link has not come up - then do not
release the LLDD resources, but rather rely on SCSI EH to handle the
timeout for these resources later on.
But if clear nexus ha calls host reset, which is the last effort of SCSI
EH, we should release all LLDD remain resources. Because SCSI EH will
release all tasks after clear nexus ha.
Before release, we do I_T nexus reset to try to clear target remain IOs.

After soft_reset() for host reset, we should not be allowed to send
commands to the HW before the PHYs have come up and the port ids have been
refreshed.
Prior to this point, any commands cannot be successfully completed.
This exclusion is achieved by grabbing the host reset semaphore.

There is a possible conflict when a device is removed and host reset occurs
concurrently.
The reason is that then the device is notified as gone, we try to clear the
ITCT, which is notified via an interrupt. The dev gone function pends on
this event with a completion, which is completed when the ITCT interrupt
occurs.
But host reset will disable all interrupts, the wait_for_completion() may
wait indefinitely.
This patch adds an semaphore to synchronise this two processes. The
semaphore is taken by the host reset as the basis of synchronising.

commands during controller reset.
When an ioctl is sent to FW, and if there is a controller reset issued
before ioctl gets completed, then in controller reset path all the pending
ioctl commands are terminated from "mpt3sas_ctl_reset_handler" function.
This will wake up the waiting ioctl commands in ioctl path and print
timeouts which are actually not timeouts.
Introduced "mpt3sas_base_check_cmd_timeout" function to check and print
whether command got timed out (or) terminated due to Host reset.

Broadcast primitive event.
Linux driver when receives Broadcast Asynchronous Event Notification (BAEN)
from the controller firmware, checks all pending I/Os at the driver level
and issues query task, abort task TMs. This is done in the driver to handle
drives which are connected with multiple initiators and undergoing target
resets. In the BAEN handling code, the I/Os issued to NVMe drives are also
handled and query task and abort task TMs are issued, which are not
necessary as there is no multi-initiator and no BAEN concept with NVMe
drives. Hence when the driver checks for pending I/Os it skips NVMe drives
at this moment.

Switchdev notifications for addition of SWITCHDEV_OBJ_ID_PORT_VLAN are
distributed not only on clean addition, but also when flags on an
existing VLAN are changed. mlxsw_sp_bridge_port_vlan_add() calls
mlxsw_sp_port_vlan_get() to get at the port_vlan in question, which
implicitly references the object. This then leads to discrepancies in

Fix by putting the port_vlan when mlxsw_sp_port_vlan_bridge_join()

Commit f34436a43092 ("net/ipv6: Simplify route replace and appending
into multipath route") changed the IPv6 route replace logic so that the
first matching route (i.e., same metric) is replaced.
Have mlxsw replace the first matching route as well.

Commit f34436a43092 ("net/ipv6: Simplify route replace and appending
into multipath route") changed the IPv6 route append logic so that
dev-only routes can be appended and not only gatewayed routes.
Align mlxsw with the new behaviour.

Johannes Berg says:
====================
A handful of fixes:
* missing RCU grace period enforcement led to drivers freeing
data structures before; fix from Dedy Lansky.
* hwsim module init error paths were messed up; fixed it myself
after a report from Colin King (who had sent a partial patch)
* kernel-doc tag errors; fix from Luca Coelho
* initialize the on-stack sinfo data structure when getting
station information; fix from Sven Eckelmann
* TXQ state dumping is now done from init, and when TXQs aren't
initialized yet at that point, bad things happen, move the
initialization; fix from Toke Høiland-Jørgensen.

stmmac reception handler calls stmmac_rx_vlan() to strip the vlan before
calling napi_gro_receive().
The function assumes VLAN tagged frames are always tagged with
802.1Q protocol, and assigns ETH_P_8021Q to the skb by hard-coding
the parameter on call to __vlan_hwaccel_put_tag() .
This causes packets not to be passed to the VLAN slave if it was created
with 802.1AD protocol
(ip link add link eth0 eth0.100 type vlan proto 802.1ad id 100).
This fix passes the protocol from the VLAN header into
__vlan_hwaccel_put_tag() instead of using the hard-coded value of
ETH_P_8021Q.
NETIF_F_HW_VLAN_STAG_RX check was added and the strip action is now
dependent on the correct combination of features and the detected vlan tag.
NETIF_F_HW_VLAN_STAG_RX feature was added to be in line with the driver
actual abilities.

We didn't free the workqueue on any errors, nor did we
correctly check for rhashtable allocation errors, nor
did we free the hashtable on error.

- make sure we only allow internally generates commands in any non-live
state
- only allow connect commands on non-live queues when actually in the
new or connecting states
- treat all other non-live, non-dead states the same as a default
cach-all
This fixes a regression where we could not shutdown a controller
orderly as we didn't allow the internal generated Property Set
command, and also ensures we don't accidentally let a Connect command
through in the wrong state.

In the ADMIN_ONLY state we don't have any I/O queues, but we should accept
all admin commands without further checks.
