Pull SCSI fixes from James Bottomley:
"Three fixes in drivers with no impact to core code.
The mptfusion fix is enormous because the driver API had to be
rethreaded to pass down the necessary iocp pointer, but once that's
done a significant chunk of code is deleted.
The other two patches are small"

scsi: mptfusion: Fix double fetch bug in ioctl
scsi: storvsc: Correctly set number of hardware queues for IDE disk
scsi: fnic: fix invalid stack access
|
|
Commit 0ed881027690 ("scsi: storvsc: setup 1:1 mapping between hardware
queue and CPU queue") introduced a regression for disks attached to
IDE. For these disks the host VSP only offers one VMBUS channel. Setting
multiple queues can overload the VMBUS channel and result in performance
drop for high queue depth workload on system with large number of CPUs.
Fix it by leaving the number of hardware queues to 1 (default value) for
IDE disks.

Apparently the code relies on the local variables occupying adjacent memory
locations in the same order, but this is of course not guaranteed.
Use an array of two u64 variables where needed to make it work correctly.
I suspect there is also an endianness bug here, but have not digged in deep
enough to be sure.

Pull SCSI fixes from James Bottomley:
"Two simple fixes in the upper drivers (so both fairly core), one in
enclosures, which fixes replugging a device into an enclosure slot and
one in the disk driver which fixes revalidating a drive with
protection information (PI) to make it a non-PI drive ... previously
we were still remembering the old PI state.
Both fixed issues are quite rare in the field"

scsi: enclosure: Fix stale device oops with hot replug
scsi: sd: Clear sdkp->protection_type if disk is reformatted without PI
|
|
If an attached disk with protection information enabled is reformatted
to Type 0 the revalidation code does not clear the original protection
type and subsequent accesses will keep setting RDPROTECT/WRPROTECT.
Set the protection type to 0 if the disk reports PROT_EN=0 in READ
CAPACITY(16).

In iscsi_if_rx func, after receiving one request through
iscsi_if_recv_msg func, iscsi_if_send_reply will be called to try to
reply to the request in a do-while loop. If the iscsi_if_send_reply
function keeps returning -EAGAIN, a deadlock will occur.
For example, a client only send msg without calling recvmsg func, then
it will result in the watchdog soft lockup. The details are given as
follows:
sock_fd = socket(AF_NETLINK, SOCK_RAW, NETLINK_ISCSI);
retval = bind(sock_fd, (struct sock addr*) & src_addr, sizeof(src_addr);
while (1) {
state_msg = sendmsg(sock_fd, &msg, 0);
//Note: recvmsg(sock_fd, &msg, 0) is not processed here.
}
close(sock_fd);

The discovering of sas port is driven by workqueue in libsas. When libsas
is processing port events or phy events in workqueue, new events may rise
up and change the state of some structures such as asd_sas_phy. This may
cause some problems such as follows:
==>thread 1 ==>thread 2
==>phy up
==>phy_up_v3_hw()
==>oob_mode = SATA_OOB_MODE;
==>phy down quickly
==>hisi_sas_phy_down()
==>sas_ha->notify_phy_event()
==>sas_phy_disconnected()
==>oob_mode = OOB_NOT_CONNECTED
==>workqueue wakeup
==>sas_form_port()
==>sas_discover_domain()
==>sas_get_port_device()
==>oob_mode is OOB_NOT_CONNECTED and device
is wrongly taken as expander
This at last lead to the panic when libsas trying to issue a command to
discover the device.

PORT UPDATE asynchronous event is generated on the host that issues PLOGI
ELS (in the case of higher WWPN). In that case, the event shouldn't be
handled as it sets unwanted DPC flags (i.e. LOOP_RESYNC_NEEDED) that

Ignore the event if the host has higher WWPN, but handle otherwise.

qla2x00_configure_local_loop sets RELOGIN_NEEDED bit and calls
qla24xx_fcport_handle_login to perform the login. This bit triggers a wake
up of DPC later after a successful login.
The deferred call is not needed if login succeeds, and it's set in
qla24xx_fcport_handle_login in case of errors, hence it should be safe to
drop.

qla2x00_configure_local_loop initializes PLOGI payload for PLOGI ELS using
Get Parameters mailbox command.
In the case when the driver is running in target mode, the topology is N2N
and the target port has higher WWPN, LOCAL_LOOP_UPDATE bit is cleared too
early and PLOGI payload is not initialized by the Get Parameters
command. That causes a failure of ELS IOCB carrying the PLOGI with 0x15 aka
Data Underrun error.
LOCAL_LOOP_UPDATE has to be set to initialize PLOGI payload.

According to FC-LS-3 (Fibre Channel Link Services) 6.3.2.4
"N_Port Login - No Fabric present", if both parties in the point-to-point
connection know N_Port_Names of each other, Nx_Port with the highest
N_Port_name shall transmit PLOGI. The specification sets no restrictions on
the port role that should send PLOGI.
However, FCP-4 (Fibre Channel Protocol for SCSI, Fourth Version) 6.2
"Overview of Process Login and Process Logout", instructs that in
point-to-point topology, initiator shall send explicit PRLI ELS.
The change fixes stuck P2P login, when target WWPN is higher than initiator
WWPN.

Target makes implicit LOGO on session teardown. LOGO ELS is not send on the
wire and initiator is not aware that target no longer wants talking to
it. Initiator keeps sending I/O requests, target responds with BA_RJT, they
time out and then initiator sends ABORT TASK (ABTS-LS).
Current behaviour incurs unneeded I/O timeout and can be fixed for some
initiators by making explicit LOGO on session deletion.

The crash can be triggered by ACL deletion when there's active I/O.
During ACL deletion, qla2xxx performs implicit LOGO that's invisible for
the initiator. Only the driver and firmware are aware of the logout.
Therefore the initiator continues to send SCSI commands and the target
always responds with SAM STATUS BUSY as it can't find the session.
The command times out after a while and initiator invokes ABORT TASK TMF
for the command. The TMF is mapped to ABTS-LS in FCP. The target can't find
session for S_ID originating ABTS-LS so it never allocates mcmd. And since
N_Port handle was deleted after LOGO, it is no longer valid and ABTS
Response IOCB is returned from firmware with status 31. Then free_mcmd is
invoked on NULL pointer and the kernel crashes.

Pull more block and io_uring updates from Jens Axboe:
"I wasn't expecting this to be so big, and if I was, I would have used
separate branches for this. Going forward I'll be doing separate
branches for the current tree, just like for the next kernel version
tree. In any case, this contains:
- Series from Christoph that fixes an inherent race condition with
zoned devices and revalidation.
- null_blk zone size fix (Damien)
- Fix for a regression in this merge window that caused busy spins by
sending empty disk uevents (Eric)
- Fix for a regression in this merge window for bfq stats (Hou)
- Fix for io_uring creds allocation failure handling (me)
- io_uring -ERESTARTSYS send/recvmsg fix (me)
- Series that fixes the need for applications to retain state across
async request punts for io_uring. This one is a bit larger than I
would have hoped, but I think it's important we get this fixed for
5.5.
- connect(2) improvement for io_uring, handling EINPROGRESS instead
of having applications needing to poll for it (me)
- Have io_uring use a hash for poll requests instead of an rbtree.
This turned out to work much better in practice, so I think we
should make the switch now. For some workloads, even with a fair
amount of cancellations, the insertion sort is just too expensive.
(me)
- Various little io_uring fixes (me, Jackie, Pavel, LimingWu)
- Fix for brd unaligned IO, and a warning for the future (Ming)
- Fix for a bio integrity data leak (Justin)
- bvec_iter_advance() improvement (Pavel)
- Xen blkback page unmap fix (SeongJae)
The major items in here are all well tested, and on the liburing side
we continue to add regression and feature test cases. We're up to 50

The current zone revalidation code has a major problem in that it
doesn't update the zone size and q->nr_zones atomically, leading
to a short window where an out of bounds access to the zone arrays
is possible.
To fix this move the setting of the zone size into the crticial
sections blk_revalidate_disk_zones so that it gets updated together
with the zone bitmaps and q->nr_zones. This also slightly simplifies
the caller as it deducts the zone size from the report_zones.
This change also allows to check for a power of two zone size in generic
code.

the fixes from the previous pull broke the build on some archs. So I'm
sending this sooner rather than later. This contains:
- Add highmem.h include for io_uring, because of the kmap() additions
from last round. For some reason the build bot didn't spot this
even though it sat for days.
- Three minor ';' removals
- Add support for the Beurer CD-on-a-chip device
- Make io_uring work on MMU-less archs"
* tag 'for-linus-20191129' of git://git.kernel.dk/linux-block:
io_uring: fix missing kmap() declaration on powerpc
ataflop: Remove unneeded semicolon
block: sunvdc: Remove unneeded semicolon
drbd: Remove unneeded semicolon
io_uring: add mapping support for NOMMU archs
sr_vendor: support Beurer GL50 evo CD-on-a-chip devices.
cdrom: respect device capabilities during opening action

Pull removal of most of fs/compat_ioctl.c from Arnd Bergmann:
"As part of the cleanup of some remaining y2038 issues, I came to
fs/compat_ioctl.c, which still has a couple of commands that need
support for time64_t.
In completely unrelated work, I spent time on cleaning up parts of
this file in the past, moving things out into drivers instead.
After Al Viro reviewed an earlier version of this series and did a lot
more of that cleanup, I decided to try to completely eliminate the
rest of it and move it all into drivers.
This series incorporates some of Al's work and many patches of my own,
but in the end stops short of actually removing the last part, which
is the scsi ioctl handlers. I have patches for those as well, but they
need more testing or possibly a rewrite"

In the case of a report zones command failure, instead of simply printing
the host_byte and driver_byte values returned, print a message that is more
human readable and useful, adding sense codes too.
To do so, use the already defined sd_print_sense_hdr() and
sd_print_result() functions by moving the declaration of these functions
into sd.h.

Commit 4fa183455988 ("scsi: qla2xxx: Utilize pci_alloc_irq_vectors/
pci_free_irq_vectors calls.") use pci_alloc_irq_vectors() to replace
pci_enable_msi() but it didn't handle the return value correctly. This bug
make qla2x00 always fail to setup MSI if MSI-X fail, so fix it.
BTW, improve the log message of return value in qla2x00_request_irqs() to
avoid confusion.

When ports are lost due to unzoning them, and the initiator port is
not part of any more zones, the GPN_FT command used for the fabric
scan may fail. In this case, the current code simply gives up after a
few retries. But if the zone is gone, all rports should actually be
marked as lost.
Fix this by jumping to the code that handles logout after GNN_FT after
scan retries are exhausted.
Fixes: f352eeb75419 ("scsi: qla2xxx: Add ability to use GPNFT/GNNFT for RSCN handling")
