VIA VT6306, VIA VT6308, and NEC OrangeLink controllers do not write
packet event codes for received PHY packets (or perhaps write
evt_no_status, hard to tell). Work around it by overwriting the
packet's ACK by ack_complete, so that upper layers that listen to PHY
packet reception get to see these packets.
(Also tested: TI TSB82AA2, TI TSB43AB22/A, TI XIO2213A, Agere FW643,
JMicron JMB381 --- these do not exhibit this bug.)
Clemens proposed a quirks flag for that, IOW whitelist known misbehaving
controllers for this workaround. Though to me it seems harmless enough
to enable for all controllers.
The log_ar_at_event() debug log will continue to show the original
status from the DMA unit.

Blackfin: bf52x/bf54x boards: drop unused nand page size
Blackfin: punt duplicate SPORT MMR defines
The string clone is only used as a temporary copy of the argument val
within the while loop, and so it should be freed before leaving the
function. The call to strsep, however, modifies clone, so a pointer to the
front of the string is kept in saved_clone, to make it possible to free it.
The sematic match that finds this problem is as follows:

Because we might be in interrupt context, replace del_timer_sync() with
del_timer(). If the timer is already running, we know that it will
clean up the transaction, so we do not need to do any further processing
in the normal transaction handler.
Many thanks to Yong Zhang for diagnosing this.

The incoming request hander fwnet_receive_packet() expects subsequent
datagram handling code to return non-zero on errors. However, almost
none of the failure paths did so. Fix them all.
(This error reporting is used to send and RCODE_CONFLICT_ERROR to the
sender node in such failure cases. Two modes of failure exist: Out of
memory, or firewire-net is unaware of any peer node to which a fragment
or an ARP packet belongs. However, it is unclear whether a sender can
actually make use of such information. A Linux peer apparently can't.
Maybe it should all be simplified to void functions.)

Fix I/O stalls with some 4-bay RAID enclosures which are based on
OXUF936QSE:
- Onnto dataTale RSM4QO, old firmware (not anymore with current
firmware),
- inXtron Hydra Super-S LCM, old as well as current firmware
when used in RAID-5 mode, perhaps also in other RAID modes.
The stalls happen during heavy or moderate disk traffic in periods that
are a multiple of 5 minutes, roughly twice per hour. They are caused
by the target responding too late to an ORB_Pointer register write:
The target responds after Split_Timeout, hence firewire-core cancels
the transaction, and firewire-sbp2 fails the SCSI request. The SCSI
core retries the request, that fails again (and again), hence SCSI core
calls firewire-sbp2's abort handler (and even the Management_Agent
register write in the abort handler has the transaction timeout
problem).
During all that, the process which issued the I/O is stalled in I/O
wait state.
Meanwhile, the target actually acts on the first failed SCSI request:
It responds to the ORB_Pointer write later (seen in the kernel log as
"firewire_core: Unsolicited response") and also finishes the SCSI
request with proper status (seen in the kernel log as "firewire_sbp2:
status write for unknown orb").
So let's just ignore RCODE_CANCELLED in the transaction callback and
wait for the target to complete the ORB nevertheless. This requires
a small modification is sbp2_cancel_orbs(); it now needs to call
orb->callback() regardless whether fw_cancel_transaction() found the
transaction unfinished or finished.
A different solution is to increase Split_Timeout on the local node.
(Tested: 2000ms timeout; maybe 1000ms or something like that works too.
200ms is insufficient. Standard is 100ms.) However, I rather not do
this because any software on any node could change the Split_Timeout to
something unsuitable. Or such a large Split_Timeout may be undesirable
for other purposes.

When an ORB was canceled (Command ORB i.e. SCSI request timed out, or
Management ORB timed out), or there was a send error in the initial
transaction, we missed to drop one of the ORB's references and thus
leaked memory.
Background:
In total, we hold 3 references to each Operation Request Block:
- 1 during sbp2_scsi_queuecommand() or sbp2_send_management_orb()
respectively,
- 1 for the duration of the write transaction to the ORB_Pointer or
Management_Agent register of the target,
- 1 for as long as the ORB stays within the lu->orb_list, until
the ORB is unlinked from the list and the orb->callback was
executed.
The latter one of these 3 references is finished
- normally by sbp2_status_write() when the target wrote status
for a pending ORB,
- or by sbp2_cancel_orbs() in case of an ORB time-out,
- or by complete_transaction() in case of a send error.
Of them, the latter two lacked the kref_put.
Add the missing kref_put()s. Add comments to the gets and puts of
references for transaction callbacks and ORB callbacks so that it is
easier to see what is supposed to happen.

There were some new formats added in commit 15c0cee6c809 "ALSA: pcm:
Define G723 3-bit and 5-bit formats". That commit increased
SNDRV_PCM_FORMAT_LAST as well. My concern is that there are a couple
places which do:
for (i = 0; i < SNDRV_PCM_FORMAT_LAST; i++) {
if (dummy->pcm_hw.formats & (1ULL << i))
snd_iprintf(buffer, " %s", snd_pcm_format_name(i));
}
I haven't tested these but it looks like if "i" were equal to
SNDRV_PCM_FORMAT_G723_24 or higher then we might read past the end of
the array.

Marks were stored on the inode and vfsmonut mark list in order from
highest memory address to lowest memory address. The code to walk those
lists thought they were in order from lowest to highest with
unpredictable results when trying to match up marks from each. It was
possible that extra events would be sent to userspace when inode
marks ignoring events wouldn't get matched with the vfsmount marks.
This problem only affected fanotify when using both vfsmount and inode
marks simultaneously.

The new sticky PCM parameter introduced the delayed clean-ups of
stream- and channel-id tags. In the current implementation, this check
(adding dirty flag) and actual clean-ups are done only for the codec
chip. However, with HD-audio architecture, multiple codecs can be
on a single bus, and the controller assign stream- and channel-ids in
the bus-wide.
In this patch, the stream-id and channel-id are checked over all codecs
connected to the corresponding bus. Together with it, the mutex is
moved to struct hda_bus, as this becomes also bus-wide.

tracing: Fix timer tracing
As discovered by Anton Blanchard, current code to autotune
tcp_death_row.sysctl_max_tw_buckets, sysctl_tcp_max_orphans and
sysctl_max_syn_backlog makes little sense.
The bigger a page is, the less tcp_max_orphans is : 4096 on a 512GB
machine in Anton's case.
(tcp_hashinfo.bhash_size * sizeof(struct inet_bind_hashbucket))
is much bigger if spinlock debugging is on. Its wrong to select bigger
limits in this case (where kernel structures are also bigger)
bhash_size max is 65536, and we get this value even for small machines.
A better ground is to use size of ehash table, this also makes code
shorter and more obvious.
Based on a patch from Anton, and another from David.

VIA VT6306, VIA VT6308, and NEC OrangeLink controllers do not write
packet event codes for received PHY packets (or perhaps write
evt_no_status, hard to tell). Work around it by overwriting the
packet's ACK by ack_complete, so that upper layers that listen to PHY
packet reception get to see these packets.
(Also tested: TI TSB82AA2, TI TSB43AB22/A, TI XIO2213A, Agere FW643,
JMicron JMB381 --- these do not exhibit this bug.)
Clemens proposed a quirks flag for that, IOW whitelist known misbehaving
controllers for this workaround. Though to me it seems harmless enough
to enable for all controllers.

The string clone is only used as a temporary copy of the argument val
within the while loop, and so it should be freed before leaving the
function. The call to strsep, however, modifies clone, so a pointer to the
front of the string is kept in saved_clone, to make it possible to free it.

Because we might be in interrupt context, replace del_timer_sync() with
del_timer(). If the timer is already running, we know that it will
clean up the transaction, so we do not need to do any further processing
in the normal transaction handler.

The incoming request hander fwnet_receive_packet() expects subsequent

none of the failure paths did so. Fix them all.
(This error reporting is used to send and RCODE_CONFLICT_ERROR to the
sender node in such failure cases. Two modes of failure exist: Out of
memory, or firewire-net is unaware of any peer node to which a fragment
or an ARP packet belongs. However, it is unclear whether a sender can
actually make use of such information. A Linux peer apparently can't.
Maybe it should all be simplified to void functions.)

Fix I/O stalls with some 4-bay RAID enclosures which are based on
OXUF936QSE:
- Onnto dataTale RSM4QO, old firmware (not anymore with current
firmware),
- inXtron Hydra Super-S LCM, old as well as current firmware
when used in RAID-5 mode, perhaps also in other RAID modes.
The stalls happen during heavy or moderate disk traffic in periods that
are a multiple of 5 minutes, roughly twice per hour. They are caused
by the target responding too late to an ORB_Pointer register write:
The target responds after Split_Timeout, hence firewire-core cancels
the transaction, and firewire-sbp2 fails the SCSI request. The SCSI
core retries the request, that fails again (and again), hence SCSI core
calls firewire-sbp2's abort handler (and even the Management_Agent
register write in the abort handler has the transaction timeout
problem).
During all that, the process which issued the I/O is stalled in I/O
wait state.
Meanwhile, the target actually acts on the first failed SCSI request:
It responds to the ORB_Pointer write later (seen in the kernel log as
"firewire_core: Unsolicited response") and also finishes the SCSI
request with proper status (seen in the kernel log as "firewire_sbp2:
status write for unknown orb").
So let's just ignore RCODE_CANCELLED in the transaction callback and
wait for the target to complete the ORB nevertheless. This requires
a small modification is sbp2_cancel_orbs(); it now needs to call
orb->callback() regardless whether fw_cancel_transaction() found the
transaction unfinished or finished.
A different solution is to increase Split_Timeout on the local node.
(Tested: 2000ms timeout; maybe 1000ms or something like that works too.
200ms is insufficient. Standard is 100ms.) However, I rather not do
this because any software on any node could change the Split_Timeout to
something unsuitable. Or such a large Split_Timeout may be undesirable
for other purposes.

When an ORB was canceled (Command ORB i.e. SCSI request timed out, or
Management ORB timed out), or there was a send error in the initial
transaction, we missed to drop one of the ORB's references and thus
leaked memory.
Background:
In total, we hold 3 references to each Operation Request Block:
- 1 during sbp2_scsi_queuecommand() or sbp2_send_management_orb()
respectively,
- 1 for the duration of the write transaction to the ORB_Pointer or
Management_Agent register of the target,
- 1 for as long as the ORB stays within the lu->orb_list, until
the ORB is unlinked from the list and the orb->callback was
executed.
The latter one of these 3 references is finished
- normally by sbp2_status_write() when the target wrote status
for a pending ORB,
- or by sbp2_cancel_orbs() in case of an ORB time-out,
- or by complete_transaction() in case of a send error.
Of them, the latter two lacked the kref_put.
Add the missing kref_put()s. Add comments to the gets and puts of
references for transaction callbacks and ORB callbacks so that it is
easier to see what is supposed to happen.

There were some new formats added in commit 15c0cee6c809 "ALSA: pcm:

places which do:
for (i = 0; i < SNDRV_PCM_FORMAT_LAST; i++) {
if (dummy->pcm_hw.formats & (1ULL << i))
snd_iprintf(buffer, " %s", snd_pcm_format_name(i));
}
I haven't tested these but it looks like if "i" were equal to
SNDRV_PCM_FORMAT_G723_24 or higher then we might read past the end of
the array.

The new sticky PCM parameter introduced the delayed clean-ups of
stream- and channel-id tags. In the current implementation, this check
(adding dirty flag) and actual clean-ups are done only for the codec
chip. However, with HD-audio architecture, multiple codecs can be
on a single bus, and the controller assign stream- and channel-ids in
the bus-wide.
In this patch, the stream-id and channel-id are checked over all codecs
connected to the corresponding bus. Together with it, the mutex is
moved to struct hda_bus, as this becomes also bus-wide.

(tcp_hashinfo.bhash_size * sizeof(struct inet_bind_hashbucket))
is much bigger if spinlock debugging is on. Its wrong to select bigger

bhash_size max is 65536, and we get this value even for small machines.
