It's a bug in commit f81c9cdc567cd3160ff9e64868d9a1a7ee226480
(Btrfs: truncate pages from clone ioctl target range)
We should pass the dest range to the truncate function, but not the
src range.
Also move the function before locking extent state.

Since the d_off in the first dirent for "." (that originates from
the 4th argument "offset" of filldir() for the 2nd dirent for "..")
is wrongly assigned in btrfs_real_readdir(), telldir returns same
offset for different locations.
| # mkfs.btrfs /dev/sdb1
| # mount /dev/sdb1 fs0
| # cd fs0
| # touch file0 file1
| # ../test
| telldir: 0
| readdir: d_off = 2, d_name = "."
| telldir: 2
| readdir: d_off = 2, d_name = ".."
| telldir: 2
| readdir: d_off = 3, d_name = "file0"
| telldir: 3
| readdir: d_off = 2147483647, d_name = "file1"
| telldir: 2147483647
To fix this problem, pass filp->f_pos (which is loff_t) instead.
| # ../test
| telldir: 0
| readdir: d_off = 1, d_name = "."
| telldir: 1
| readdir: d_off = 2, d_name = ".."
| telldir: 2
| readdir: d_off = 3, d_name = "file0"
:
At the moment the "offset" for "." is unused because there is no
preceding dirent, however it is better to pass filp->f_pos to follow
grammatical usage.

Reordered the BT ST channel registration, to make sure that the
event channel is registered before all others. This prevents a
situation where incoming events may cause kernel panic in the ST
driver if the event channel is not yet registered to handle
incoming events.In addition, the deregistration of the channels
was also modified, to be in the reversed order of the registration,
to allow the event channel to be the last one unregistered.

Current IPv6 implementation uses inetpeer to store metrics for
routes. The problem of inetpeer is that it doesn't take subnet
prefix length in to consideration. If two routes have the same
address but different prefix length, they share same inetpeer.
So changing metrics of one route also affects the other. The
fix is to allocate separate metrics storage for each route.

This patch fixes a bug in the iscsit_fe_sendpage_sg() transmit codepath that
was originally introduced with the v3.1 iscsi-target merge that incorrectly
uses hardcoded cmd->iov_data_count values to determine cmd->iov_data[] offsets
for extra outgoing padding and DataDigest payload vectors.
This code is obviously incorrect for the DataDigest enabled case with sendpage
offload, and this fix ensures correct operation for padding + DataDigest,
padding only, and DataDigest only cases. The bug was introduced during a
pre-merge change in iscsit_fe_sendpage_sg() to natively use struct scatterlist
instead of the legacy v3.0 struct se_mem logic.

Attempt to reduce the number of IP packets emitted in response to single
SCTP packet (2e3216cd) introduced a complication - if a packet contains
two COOKIE_ECHO chunks and nothing else then SCTP state machine corks the
socket while processing first COOKIE_ECHO and then loses the association
and forgets to uncork the socket. To deal with the issue add new SCTP
command which can be used to set association explictly. Use this new
command when processing second COOKIE_ECHO chunk to restore the context
for SCTP state machine.

This patch makes iscsi-target explictly disable OFMarker=Yes and IFMarker=yes
parameter key usage during iscsi login by setting IFMarkInt_Reject and
OFMarkInt_Reject values in iscsi_enforce_integrity_rules() to effectively
disable iscsi marker usage. With this patch, an initiator proposer asking
to enable either marker parameter keys will be issued a 'No' response, and
the target sets OFMarkInt + IFMarkInt parameter key response to 'Irrelevant'.
With markers disabled during iscsi login, this patch removes the problematic
on-stack local-scope array for marker intervals in iscsit_do_rx_data() +
iscsit_do_tx_data(), and other related marker code in iscsi_target_util.c.
This fixes a potentional stack smashing scenario with small range markers

This patch adds target_parse_naa_6h_vendor_specific() to address a bug where the
conversion of PRODUCT SERIAL NUMBER to use hex2bin() in target_emulate_evpd_83()
was not doing proper isxdigit() checking. This conversion of the vpd_unit_serial
configifs attribute is done while generating a VPD=0x83 NAA IEEE Registered
Extended DESIGNATOR format's 100 bits of unique VENDOR SPECIFIC IDENTIFIER +
VENDOR SPECIFIC IDENTIFIER EXTENSION area.
This patch allows vpd_unit_serial (VPD=0x80) and the T10 Vendor ID DESIGNATOR
format (VPD=0x83) to continue to use free-form variable length ASCII values,
and now skips any non hex characters for fixed length NAA IEEE Registered Extended
DESIGNATOR format (VPD=0x83) requring the binary conversion.
This was originally reported by Martin after the v3.1-rc1 change to use hex2bin()
in commit 11650b859681e03fdbf26277fcfc5f1f62186703 where the use of non hex
characters in vpd_unit_serial generated different values than the original
v3.0 internal hex -> binary code. This v3.1 change caused a problem with
filesystems who write a NAA DESIGNATOR onto it's ondisk metadata, and this patch
will (again) change existing values to ensure that non hex characters are not
included in the fixed length NAA DESIGNATOR.
Note this patch still expects vpd_unit_serial to be set via existing userspace
methods of uuid generation, and does not do strict formatting via configfs input.

During the association, the regulatory is updated by country IE
that reaps the previously found beacons. The impact is that
after a STA disconnects *or* when for any reason a regulatory
domain change happens the beacon hint flag is not cleared
therefore preventing future beacon hints to be learned.
This is important as a regulatory domain change or a restore
of regulatory settings would set back the passive scan and no-ibss
flags on the channel. This is the right place to do this given that
it covers any regulatory domain change.

Problem: Changed from wake_up_interruptible -> wake_up_process and
wait_event_interruptible-> schedule_timeout_interruptible broke the FCoE
target. Earlier approach of wake_up_interruptible was also looking at
'queue_cnt' which is not necessary, because it increment of 'queue_cnt'
with wake_up_inetrriptible / waker_up_process introduces race condition.
Fix: Instead of fixing the code which used wake_up_process and remove
'queue_cnt', using work_queue based approach is cleaner and acheives
same result. As well, work queue based approach has less programming
overhead and OS manages threads which processes work queues.

Problem: HW DDP context wasn;t invalidated in case of ABORTS, etc...
This leads to the problem where memory pages which are used for DDP
as user descriptor could get reused for some other purpose (such as to
satisfy new memory allocation request either by kernel or user mode threads)
and since HW DDP context was not invalidated, HW continue to write to
those pages, hence causing memory corruption.
Fix: Either on incoming ABORTS or due to exchange time out, allowed the
target to cleanup HW DDP context if it was setup for respective ft_cmd.
Added new function to perform this cleanup, furthur it can be enhanced
for other cleanup activity.
Additinal Notes: To avoid calling ddp_done from multiple places, composed
the functionality in helper function "ft_invl_hw_context" and it is being
called from multiple places. Cleaned up code in function "ft_recv_write_data"
w.r.t DDP.

When work is scheduled with schedule_work(), the work can end up
running on multiple CPUs at the same time -- this happens if
the work is already running on one CPU and schedule_work() is called
on another CPU. This leads to list corruption with target_qf_do_work(),
which is roughly doing:
spin_lock(...);
list_for_each_entry_safe(...) {
list_del(...);
spin_unlock(...);
// do stuff
spin_lock(...);
}
With multiple CPUs running this code, one CPU can end up deleting the
list entry that the other CPU is about to work on.
Fix this by splicing the list entries onto a local list and then
operating on that in the work function. This way, each invocation of
target_qf_do_work() operates on its own local list and so multiple
invocations don't corrupt each other's list. This also avoids dropping
and reacquiring the lock for each list entry.

On x86-64, they were just wasteful: with the explicitly added (now
unnecessary) padding, the size of the alternatives structure was 16
bytes, and an alignment of 8 bytes didn't hurt much.
However, it was still silly, since the natural size and alignment for
the structure is actually just 12 bytes, 4-byte aligned since commit
59e97e4d6fbc ("x86: Make alternative instruction pointers relative").
So removing the padding, and removing the extra alignment is just a good
idea.
On x86-32, the alignment of 4 bytes was correct, but was incorrectly
hardcoded as 8 bytes in <asm/alternative-asm.h>. That header file had
used to be an x86-64 only header file, but various unification efforts
have made it be used for x86-32 too (ie the unification of rwlock and
rwsem).
That in turn caused x86-32 boot failures, because the extra alignment
would result in random zero-filled words in the altinstructions section,
causing oopses early at boot when doing alternative instruction
replacement.
So just remove all the alignment noise entirely. It's wrong, and it's
unnecessary. The section itself is already properly aligned by the
linker scripts, and all additions to the section had better be of the
proper 12-byte format, keeping it aligned. So if the align directive
were to ever make a difference, that would be an indication of a serious
bug to begin with.

d88733150 introduced the IFF_SKB_TX_SHARING flag, which I unilaterally set in
ether_setup. In doing this I didn't realize that other flags (such as
IFF_XMIT_DST_RELEASE) might be set prior to calling the ether_setup routine.
This patch changes ether_setup to or in SKB_TX_SHARING so as not to
inadvertently clear other existing flags. Thanks to Pekka Riikonen for pointing
out my error

dev_forward_skb loops an skb back into host networking
stack which might hang on the memory indefinitely.
In particular, this can happen in macvtap in bridged mode.
Copy the userspace fragments to avoid blocking the
sender in that case.
As this patch makes skb_copy_ubufs extern now,
I also added some documentation and made it clear
the SKBTX_DEV_ZEROCOPY flag automatically instead
of doing it in all callers. This can be made into a separate
patch if people feel it's worth it.

flow_cache_lookup will return a cached object (or null pointer) that the
resolver (i.e. xfrm_policy_lookup) previously found for another namespace
using the same key/family/dir. Instead, make the namespace part of what
identifies entries in the cache.
As before, flow_entry_valid will return 0 for entries where the namespace
has been deleted, and they will be removed from the cache the next time
flow_cache_gc_task is run.
