Add a "no_turs" flag to _scsih_ublock_io_all_device() to optionally skip
TEST UNIT READY (TUR) checks while unblocking devices. This is used
after broadcast events where sending TURs is not required.

Justin Tee <justintee8345@gmail.com> says:
Update lpfc to revision 14.4.0.13
This patch set introduces reporting encryption information for Fibre
Channel HBAs.
First, the scsi_transport_fc layer is updated to include a new
fc_encryption_info attribute that is added to struct fc_rport.
Supporting sysfs and LLDD templates are provided.
Then, the lpfc driver is updated to utilize the new templates for
reporting encrypted fibre channel connections to upper layer.
The patches were cut against Martin's 6.19/scsi-queue tree.

Support logging encryption events in both point-to-point and fabric
topologies. A new LOG_ENCRYPTION flag is defined for reporting
encryption related events for HBAs that support the FEDIF feature.
Encryption information is stored in each NDLP object, which is
determined during the discovery stage after PLOGI completes.
For reporting encryption information to upper layers, the
.get_fc_rport_enc_info routine is implemented in lpfc_get_enc_info().
This allows encryption status to be reported through fc_remote_ports
sysfs. Debugfs is also updated to report encryption information for all
NDLP objects.

Introduce a new structure for reporting an encrypted session over an
fc_rport. The encryption group is added as an attribute in struct
fc_rport and reports information in fc_encryption_info. This structure
contains a status member variable, which stores a bit value indicating
an encrypted session.

sdebug_defer.defer_t
Using READ/WRITE_ONCE() means that the read or write is not torn by the
compiler.
READ/WRITE_ONCE() is always used when accessing sdebug_defer.defer_t.
However, we also guard the access in a spinlock when accessing that
member, and spinlock already guarantees no tearing, so stop using
READ/WRITE_ONCE().

The driver defines as follows pr_fmt:
#define pr_fmt(fmt) KBUILD_MODNAME ":%s: " fmt, __func__
...meaning that we already get the function name added in any debug
statements.
Remove using of __func__ in debug logs to avoid the duplication.
For instances of where the function name was being printed, add some
verbose comment to avoid using "" (which would be a bit silly).
It would be nicer to stop using pr_fmt(), but that would mean rewriting
approx 100 debug statements to have a sensible and clear message.

A race condition was found in sg_proc_debug_helper(). It was observed on
a system using an IBM LTO-9 SAS Tape Drive (ULTRIUM-TD9) and monitoring
/proc/scsi/sg/debug every second. A very large elapsed time would
sometimes appear. This is caused by two race conditions.
We reproduced the issue with an IBM ULTRIUM-HH9 tape drive on an x86_64
architecture. A patched kernel was built, and the race condition could
not be observed anymore after the application of this patch. A
reproducer C program utilising the scsi_debug module was also built by
Changhui Zhong and can be viewed here:
https://github.com/MichaelRabek/linux-tests/blob/master/drivers/scsi/sg/sg_race_trigger.c
The first race happens between the reading of hp->duration in
sg_proc_debug_helper() and request completion in sg_rq_end_io(). The
hp->duration member variable may hold either of two types of
information:
#1 - The start time of the request. This value is present while
the request is not yet finished.
#2 - The total execution time of the request (end_time - start_time).
If sg_proc_debug_helper() executes *after* the value of hp->duration was
changed from #1 to #2, but *before* srp->done is set to 1 in
sg_rq_end_io(), a fresh timestamp is taken in the else branch, and the
elapsed time (value type #2) is subtracted from a timestamp, which
cannot yield a valid elapsed time (which is a type #2 value as well).
To fix this issue, the value of hp->duration must change under the
protection of the sfp->rq_list_lock in sg_rq_end_io(). Since
sg_proc_debug_helper() takes this read lock, the change to srp->done and
srp->header.duration will happen atomically from the perspective of
sg_proc_debug_helper() and the race condition is thus eliminated.
The second race condition happens between sg_proc_debug_helper() and
sg_new_write(). Even though hp->duration is set to the current time
stamp in sg_add_request() under the write lock's protection, it gets
overwritten by a call to get_sg_io_hdr(), which calls copy_from_user()
to copy struct sg_io_hdr from userspace into kernel space. hp->duration
is set to the start time again in sg_common_write(). If
sg_proc_debug_helper() is called between these two calls, an arbitrary
value set by userspace (usually zero) is used to compute the elapsed
time.
To fix this issue, hp->duration must be set to the current timestamp
again after get_sg_io_hdr() returns successfully. A small race window
still exists between get_sg_io_hdr() and setting hp->duration, but this
window is only a few instructions wide and does not result in observable
issues in practice, as confirmed by testing.
Additionally, we fix the format specifier from %d to %u for printing
unsigned int values in sg_proc_debug_helper().

It also utilizes a hardcoded magic number (0x2) for the enable bit.
Use ufshcd_rmwl() helper, replace the magic number with the

A recent commit modified struct irdma_alloc_ucontext_resp by adding a
member with implicit padding in front of it, though this does not change
the offset of the data members other than m68k. Reported by
scripts/check-uapi.sh:
==== ABI differences detected in include/rdma/irdma-abi.h from 1dd7bde2e91c -> HEAD ====
[C] 'struct irdma_alloc_ucontext_resp' changed:
type size changed from 704 to 640 (in bits)
1 data member deletion:
'__u8 rsvd3[2]', at offset 640 (in bits) at irdma-abi.h:61:1
1 data member insertion:
'__u8 revd3[2]', at offset 592 (in bits) at irdma-abi.h:60:1
Change the size back to the previous version, and remove the implicit
padding by making it explicit and matching what x86-64 would do by placing
max_hw_srq_quanta member into a naturally aligned location.

Add explicit padding into the rdma_ucm_query_ib_service_resp and
rdma_ucm_resolve_ib_service structures that embed it, so that the layout
is compatible across all of them.
This is an ABI change on i386, aligning it with x86_64 and the other

The netlink response for RDMA_NL_LS_OP_IP_RESOLVE should always have a
LS_NLA_TYPE_DGID attribute, it is invalid if it does not.
Use the nl parsing logic properly and call nla_parse_deprecated() to fill
the nlattrs array and then directly index that array to get the data for
the DGID. Just fail if it is NULL.
Remove the for loop searching for the nla, and squash the validation and
parsing into one function.
Fixes an uninitialized read from the stack triggered by userspace if it
does not provide the DGID to a kernel initiated RDMA_NL_LS_OP_IP_RESOLVE
query.

Apart from runtime PM, there is nothing in common between i2c_dw_xfer()
and amd_i2c_dw_xfer_quirk(), so give AMD NAVI controller its own algorithm
instead of calling the quirk from i2c_dw_xfer().
Add runtime PM handling to amd_i2c_dw_xfer_quirk() and a dedicated
i2c_algorithm for AMD NAVI controllers. The adapter algorithm is set
during probe based on the device model.
This way we avoid checking for the device model at the start of every
transfer.

Optimize the i2c_dw_read() function by reading the message flags only
once per message, rather than for every byte.
The message flags are accessed both in the outer loop and the inner loop,
so move the declaration of the local flags variable to the outer loop.
The message index is only modified by the outer loop, so reading the
flags in the inner loop was always getting the same value.
