Pull networking fixes from David Miller:
1) Make sure SKB control block is in the proper state during IPSEC
ESP-in-TCP encapsulation. From Sabrina Dubroca.
2) Various kinds of attributes were not being cloned properly when we
build new xfrm_state objects from existing ones. Fix from Antony
Antony.

Jha.
8) Use correct address family in xfrm state lookups, from Herbert Xu.
9) A bridge FDB flush should not clear out user managed fdb entries
with the ext_learn flag set, from Nikolay Aleksandrov.
10) Fix nested locking of netdev address lists, from Taehee Yoo.
11) Fix handling of 32-bit DATA_FIN values in mptcp, from Mat Martineau.

13) Don't free command entries in mlx5 while comp handler could still be
running, from Eran Ben Elisha.
14) Error flow of request_irq() in mlx5 is busted, due to an off by one
we try to free and IRQ never allocated. From Maor Gottlieb.
15) Fix leak when dumping netlink policies, from Johannes Berg.
16) Sendpage cannot be performed when a page is a slab page, or the page

In iscsci driver, iscsi_tcp_segment_map() uses the following code to
check whether the page should or not be handled by sendpage:
if (!recv && page_count(sg_page(sg)) >= 1 && !PageSlab(sg_page(sg)))
The "page_count(sg_page(sg)) >= 1 && !PageSlab(sg_page(sg)" part is to
make sure the page can be sent to network layer's zero copy path. This
part is exactly what sendpage_ok() does.
This patch uses use sendpage_ok() in iscsi_tcp_segment_map() to replace
the original open coded checks.

scsi: iscsi: iscsi_tcp: Avoid holding spinlock while calling getpeername()
scsi: target: Fix lun lookup for TARGET_SCF_LOOKUP_LUN_FROM_TAG case
|
|
The kernel may fail to boot or devices may fail to come up when
initializing iscsi_tcp devices starting with Linux 5.8.
Commit a79af8a64d39 ("[SCSI] iscsi_tcp: use iscsi_conn_get_addr_param
libiscsi function") introduced getpeername() within the session spinlock.
Commit 1b66d253610c ("bpf: Add get{peer, sock}name attach types for
sock_addr") introduced BPF_CGROUP_RUN_SA_PROG_LOCK() within getpeername(),
which acquires a mutex and when used from iscsi_tcp devices can now lead to
"BUG: scheduling while atomic:" and subsequent damage.
Ensure that the spinlock is released before calling getpeername() or
getsockname(). sock_hold() and sock_put() are used to ensure that the
socket reference is preserved until after the getpeername() or
getsockname() complete.

Pull SCSI fixes from James Bottomley:
"Three fixes: one in drivers (lpfc) and two for zoned block devices.
The latter also impinges on the block layer but only to introduce a

Make sure to call sd_zbc_init_disk() when the sdkp->zoned field is known,
that is, once sd_read_block_characteristics() is executed in
sd_revalidate_disk(), so that host-aware disks also get initialized. To do
so, move sd_zbc_init_disk() call in sd_zbc_revalidate_zones() and make sure
to execute it for all zoned disks, including for host-aware disks used as
regular disks as these disk zoned model may be changed back to BLK_ZONED_HA
when partitions are deleted.

When CONFIG_BLK_DEV_ZONED is disabled, allow using host-aware ZBC disks as
regular disks. In this case, ensure that command completion is correctly
executed by changing sd_zbc_complete() to return good_bytes instead of 0
and causing a hang during device probe (endless retries).
When CONFIG_BLK_DEV_ZONED is enabled and a host-aware disk is detected to
have partitions, it will be used as a regular disk. In this case, make sure
to not do anything in sd_zbc_revalidate_zones() as that triggers warnings.
Since all these different cases result in subtle settings of the disk queue
zoned model, introduce the block layer helper function
blk_queue_set_zoned() to generically implement setting up the effective
zoned model according to the disk type, the presence of partitions on the
disk and CONFIG_BLK_DEV_ZONED configuration.

Initial FLOGIs are failing with the following message:
lpfc 0000:13:00.1: 1:(0):0820 FLOGI Failed (x300). BBCredit Not Supported
In a prior patch, the READ_SPARAM command was re-ordered to post after
CONFIG_LINK as the driver is expected to update the driver's copy of the
service parameters for the FLOGI payload. If the bb-credit recovery feature
is enabled, this is fine. But on adapters were bb-credit recovery isn't
enabled, it would cause the FLOGI to fail.
Fix by restoring the original command order (READ_SPARAM before
CONFIG_LINK), and after issuing CONFIG_LINK, detect bb-credit recovery
support and reissuing READ_SPARAM to obtain the updated service parameters
(effectively adding in the fix command order).

In sas_notify_lldd_dev_found(), if we can't allocate the necessary
resources, then it seems like the wrong thing to mark the device as found
and to increment the reference count. None of the callers ever drop the
reference in that situation.

It was discovered that sdparm will fail when attempting to disable write
cache on a SATA disk connected via libsas.
In the ATA command set the write cache state is controlled through the SET
FEATURES operation. This is roughly corresponds to MODE SELECT in SCSI and
the latter command is what is used in the SCSI-ATA translation layer. A
subtle difference is that a MODE SELECT carries data whereas SET FEATURES
is defined as a non-data command in ATA.
Set the DMA data direction to DMA_NONE if the requested ATA command is
identified as non-data.

The driver is unable to successfully login with remote device. During pt2pt
login, the driver completes its FLOGI request with the remote device having
WWN precedence. The remote device issues its own (delayed) FLOGI after
accepting the driver's and, upon transmitting the FLOGI, immediately
recognizes it has already processed the driver's FLOGI thus it transitions
to sending a PLOGI before waiting for an ACC to its FLOGI.
In the driver, the FLOGI is received and an ACC sent, followed by the PLOGI
being received and an ACC sent. The issue is that the PLOGI reception
occurs before the response from the adapter from the FLOGI ACC is
received. Processing of the PLOGI sets state flags to perform the REG_RPI
mailbox command and proceed with the rest of discovery on the port. The
same completion routine used by both FLOGI and PLOGI is generic in
nature. One of the things it does is clear flags, and those flags happen to
drive the rest of discovery. So what happened was the PLOGI processing set
the flags, the FLOGI ACC completion cleared them, thus when the PLOGI ACC
completes it doesn't see the flags and stops.
Fix by modifying the generic completion routine to not clear the rest of
discovery flag (NLP_ACC_REGLOGIN) unless the completion is also associated
with performing a mailbox command as part of its handling. For things such
as FLOGI ACC, there isn't a subsequent action to perform with the adapter,
thus there is no mailbox cmd ptr. PLOGI ACC though will perform REG_RPI
upon completion, thus there is a mailbox cmd ptr.

resp_open_zone() always calls zbc_open_zone() with parameter explicit set
to true.
If zbc_open_zone() is called with parameter explicit set to true, and the
current zone state is implicit open, it will call zbc_close_zone() on the
zone before proceeding.
Therefore, there is no need for resp_open_zone() to call zbc_close_zone()
on an implicitly open zone before calling zbc_open_zone().
Remove superfluous close zone in resp_open_zone().

Multipath errors were seen during failback due to login timeout. The
remote device sent LOGO, the local host tore down the session and did
relogin. The RSCN arrived indicates remote device is going through failover
after which the relogin is in a 20s timeout phase. At this point the
driver is stuck in the relogin process. Add a fix to delete the session as
part of abort/flush the login.

John Garry reported 'sdebug_q_cmd_complete: scp is NULL' failures that were
mainly seen on aarch64 machines (e.g. RPi 4 with four A72 CPUs). The
problem was tracked down to a missing critical section on a "short circuit"
path. Namely, the time to process the current command so far has already
exceeded the requested command duration (i.e. the number of nanoseconds in
the ndelay parameter).
The random=1 parameter setting was pivotal in finding this error. The
failure scenario involved first taking that "short circuit" path (due to a
very short command duration) and then taking the more likely
hrtimer_start() path (due to a longer command duration). With random=1 each
command's duration is taken from the uniformly distributed [0..ndelay)
interval. The fio utility also helped by reliably generating the error
scenario at about once per minute on a RPi 4 (64 bit OS).

If the bit corresponding to a task in the Doorbell register has been
cleared, no need to poll the status of the task on the device side and to
send an Abort Task TM. Instead, let it directly goto cleanup.
In addition, to keep original debug output, move the goto below the debug
print.

If somehow no interrupt notification is raised for a completed request and
its doorbell bit is cleared by host, UFS driver needs to cleanup its
outstanding bit in ufshcd_abort(). Otherwise, system may behave abnormally
in the following scenario:
After ufshcd_abort() returns, this request will be requeued by SCSI layer
with its outstanding bit set. Any future completed request will trigger
ufshcd_transfer_req_compl() to handle all "completed outstanding bits". At
this time the "abnormal outstanding bit" will be detected and the "requeued
request" will be chosen to execute request post-processing flow. This is
wrong because this request is still "alive".

In ufshcd_suspend(), after clk-gating is suspended and link is set
as Hibern8 state, ufshcd_hold() is still possibly invoked before
ufshcd_suspend() returns. For example, MediaTek's suspend vops may
issue UIC commands which would call ufshcd_hold() during the command
issuing flow.
Now if UFSHCD_CAP_HIBERN8_WITH_CLK_GATING capability is enabled,
then ufshcd_hold() may enter infinite loops because there is no
clk-ungating work scheduled or pending. In this case, ufshcd_hold()
shall just bypass, and keep the link as Hibern8 state.
