44d13be6ec DMI: allow omitting ident strings in DMI tables
commit 75757507e0 upstream.

The purpose of dmi->ident is twofold - it may be used by DMI callback
functions when composing log messages; it is also used to determine
end of DMI table in dmi_check_system() and dmi_first_match(). However,
in case when callbacks are not interested in using ident at all it just
wastes memory. Let's make entries with empty first match slot serve as
end-of-table markers instead.

[needed for DMI table changes that need to be done by later patches - gkh]

5172b4b0f1 PCI: AER: fix aer inject result in kernel oops
commit 46256f83d0 upstream.

If the BIOS does not export _OSC to allow OS take over the PCIe AER, the
pcie aer driver will not initialize the aer service. However, the
aer_inject driver does not check this scenario, which results in a kernel

e166cb138d fcoe, libfc: fix an libfc issue with queue ramp down in libfc
commit 14caf44c69 upstream.

The cmd_per_lun value is used by scsi-ml as fall back lowest
queue_depth value but in case of libfc cmd_per_lun is set to
same value as max queue_depth = 32.

So this patch reduces cmd_per_lun value to 3 and configures
each lun with default max queue_depth 32 in fc_slave_alloc.

2792e0ceb2 libfc: remote port gets stuck in restart state without really restarting
commit 5543c72e2b upstream.

We ran into a scenario where a remote port goes into RESTART state, but
never gets added to scsi transport. The running vmcore showed the following:
a) Port was in RESTART state
b) rdata->event was STOP
c) no work gets scheduled for the remote work to fc_rport_work

After this point, shut/no-shut of the remote port did not cause the port
to get re-discovered. The port would move betwen DELETE and RESTART states,
but the event would always be STOP, no work would get scheduled to
fc_rport_work and the port would not get added to scsi_transport.

The problem is that rdata->event is not set to NONE after a port is
restarted. After this point, no more work gets scheduled for the remote port
since new work is scheduled only if rdata->event is non-NONE. So, the event
and state keep changing, but fc_rport_work does not get scheduled to actually
handle the event.

Here's a transition of states that explains the above observation:

) Port is first in READY State, event is NONE

2) RSCN on shut, port goes to DELETED, event is stop

3) Before fc_rport_work runs, RSCN on no-shut, port goes to RESTART, event is
still STOP

4) fc_rport_work gets scheduled, removes the port from transport, sees state
as RESTART, begins the PLOGI state machine, event remains as STOP (event NOT
changed to NONE, this is the bug)

5) Plogi state machine completes, port state goes to READY, event goes to
READY, but no work is scheduled since event was STOP (non-NONE) before.
Fc_rport_work is not scheduled, port remains in READY state, but is not added
to transport.

Things are broken at this point. Libfc rport is ready, but no transport rport
created.

6) now a shut causes port state to change to DELETE, event to change to STOP,
no work gets scheduled

7) no-shut causes port state to change to RESTART, event remains at STOP,
no work gets scheduled

(6) and (7) now get repeated everytime we do shut/no-shut. No way to get out
of this state. Fcc reset does not help too.

Only way to get out is to load/unload module.

Fix is to set rdata->event to NONE while processing the STOP/LOGO/FAILED
events, inside the discovery and rport locks.

407590ad18 libfc: fix free of fc_rport_priv with timer pending
commit b4a9c7ede9 upstream.

Timer crashes were caused by freeing a struct fc_rport_priv
with a timer pending, causing the timer facility list to be
corrupted.  This was during FC uplink flap tests with a lot
of targets.

After discovery, we were doing an PLOGI on an rdata that was
in DELETE state but not yet removed from the lookup list.
This moved the rdata from DELETE state to PLOGI state.
If the PLOGI exchange allocation failed and needed to be
retried, the timer scheduling could race with the free
being done by fc_rport_work().

When fc_rport_login() is called on a rport in DELETE state,
move it to a new state RESTART.  In fc_rport_work, when
handling a LOGO, STOPPED or FAILED event, look for restart
state.  In the RESTART case, don't take the rdata off the
list and after the transport remote port is deleted and
exchanges are reset, re-login to the remote port.

Note that the new RESTART state also corrects a problem we
had when re-discovering a port that had moved to DELETE state.
In that case, a new rdata was created, but the old rdata
would do an exchange manager reset affecting the FC_ID
for both the new rdata and old rdata.  With the new state,
the new port isn't logged into until after any old exchanges
are reset.

a3d46ca93e libfc: fix memory corruption caused by double frees and bad error handling
commit 8f550f937e upstream.

I was running into several different panics under stress, which I traced down
to a few different possible slab corruption issues in error handling paths.
I have not yet looked into why these exchange sends fail, but with these
fixes my test system is much more stable under stress than before.

fc_elsct_send() could fail and either leave the passed in frame intact
(failure in fc_ct/els_fill) or the frame could have been freed if the
failure was is fc_exch_seq_send().  The caller had no way of knowing, and
there was a potential double free in the error handling in fc_fcp_rec().

Make fc_elsct_send() always free the frame before returning, and remove the
fc_frame_free() call in fc_fcp_rec().

While fc_exch_seq_send() did always consume the frame, there were double free
bugs in the error handling of fc_fcp_cmd_send() and fc_fcp_srr() as well.

Numerous calls to error handling routines (fc_disc_error(),
fc_lport_error(), fc_rport_error_retry() ) were passing in a frame pointer that
had already been freed in the case of an error.  I have changed the call
sites to pass in a NULL pointer, but there may be more appropriate error
codes to use.

Question:  Why do these error routines take a frame pointer anyway?  I
understand passing in a pointer encoded error to the response handlers, but
the error routines take no action on a valid pointer and should never be
called that way.

In case of sequence offload, in fc_fcp_send_data(), the skb_fill_page_info()

exceeding SKB_MAX_FRAGS, this eventually corrupts the memory. I am adding the
FR_FRAME_SG_LEN back, but as SKB_MAX_FRAGS -1, leaving 1 for our fcoe_eof_crc
page. And send will be broken into multiple large sends if the frame already
contains more frags than skb handle.

56320f6e40 libfc: Fix wrong scsi return status under FC_DATA_UNDRUN
commit 4347fa6687 upstream.

This bug is exposed when there is a link flap in LLD. Particularly, when it
happens right after a SCSI write command is sent out, no FCP_DATA is sent,
causing fsp->status_code to be set as FC_DATA_UNDRUN in fc_fcp_complete_locked
even no SCSI status is received. Consequently, fc_io_compl treats this as DID_OK.
This results in SCSI returning successful to the initial I/O request even
there is no DATA actually sent. Particularly, if you run an I/O tool w/ data
verification on, the read back for verification is gonna fail.

This is fixed here by checking when FC_DATA_UNDRUN happens, SCSI status is
received w/ FC_SRB_RCV_STATUS set in fsp->state.

commit 8798a694da upstream.

I was doing some large lun count testing with 2.6.31 and hit
a BUG_ON() in fc_timeout_deleted_rport(), and it seems like it
should have been just a matter of time before someone did.

It seems invalid to set port_state under lock, then expect it to
remain set after releasing the lock.  Another thread called
fc_remote_port_add() when the lock was released, changing the
port_state.

This patch removes the BUG_ON and moves the test of the
port_state to inside the host_lock.  It's been running for
several weeks now with no ill effect.

001252f8ea HID: fixup quirk for NCR devices
commit 5b915d9e6d upstream.

NCR devices are terminally broken by design -- they claim themselves to contain
proper input applications in their HID report descriptor, but behave very badly
if treated in standard way.

According to NCR developers, the devices get confused when queried for reports
in a standard way, rendering them unusable.

NCR is shipping application called "RPSL" that can be used to drive these
devices through hiddev, under the assumption that in-kernel driver doesn't
perform initial report query.
If it does, neither in-kernel nor hiddev-based driver can operate with these
devices any more.

Introduce a quirk that skips the report query for all NCR devices. The previous
NOGET quirk was wrong and had been introduced because I misunderstood the nature
of brokenness of these devices.

5e057878f9 NFS: Revert default r/wsize behavior
commit dd47f96c07 upstream.

When the "rsize=" or "wsize=" mount options are not specified,
text-based mounts have slightly different behavior than legacy binary
mounts.  Text-based mounts use the smaller of the server's maximum
and the client's maximum, but binary mounts use the smaller of the
server's _preferred_ size and the client's maximum.

This difference is actually pretty subtle.  Most servers advertise
the same value as their maximum and their preferred transfer size, so
the end result is the same in most cases.

The reason for this difference is that for text-based mounts, if
r/wsize are not specified, they are set to the largest value supported
by the client.  For legacy mounts, the values are set to zero if these
options are not specified.

nfs_server_set_fsinfo() can negotiate the transfer size defaults
correctly in any case.  There's no need to specify any particular
value as default in the text-based option parsing logic.

Note that nfs4 doesn't use nfs_server_set_fsinfo(), but the mount.nfs4
command does set rsize and wsize to 0 if the user didn't specify these
options.  So, make the same change for text-based NFSv4 mounts.

Thanks to James Pearson <james-p@moving-picture.com> for reporting and
diagnosing the problem.

83886fa2a0 PCI: Always set prefetchable base/limit upper32 registers
commit 59353ea30e upstream.

Prior to 1f82de10 we always initialized the upper 32bits of the
prefetchable memory window, regardless of the address range used.
Now we only touch it for a >32bit address, which means the upper32
registers remain whatever the BIOS initialized them too.

It's valid for the BIOS to set the upper32 base/limit to
0xffffffff/0x00000000, which makes us program prefetchable ranges
like 0xffffffffabc00000 - 0x00000000abc00000

Revert the chunk of 1f82de10 that made this conditional so we always
write the upper32 registers and remove now unused pref_mem64 variable.

34911bf203 nfsd: Fix sort_pacl in fs/nfsd/nf4acl.c to actually sort groups
commit aba24d7158 upstream.

We have been doing some extensive testing of Linux support for ACLs on
NFDS v4. We have noticed that the server rejects ACLs where the groups
are out of order, for example, the following ACL is rejected:

A::OWNER@:rwaxtTcCy
A::user101@domain:rwaxtcy
A::GROUP@:rwaxtcy
A:g:group102@domain:rwaxtcy
A:g:group101@domain:rwaxtcy
A::EVERYONE@:rwaxtcy

Examining the server code, I found that after converting an NFS v4 ACL
to POSIX, sort_pacl is called to sort the user ACEs and group ACEs.
Unfortunately, a minor bug causes the group sort to be skipped.

a9238ce3bb nohz: Prevent clocksource wrapping during idle
commit 98962465ed upstream.

The dynamic tick allows the kernel to sleep for periods longer than a
single tick, but it does not limit the sleep time currently. In the
worst case the kernel could sleep longer than the wrap around time of
the time keeping clock source which would result in losing track of
time.

Prevent this by limiting it to the safe maximum sleep time of the
current time keeping clock source. The value is calculated when the
clock source is registered.

e96610c648 partitions: use sector size for EFI GPT
commit 7d13af3279 upstream.

Currently, kernel uses strictly 512-byte sectors for EFI GPT parsing.
That's wrong.

UEFI standard (version 2.3, May 2009, 5.3.1 GUID Format overview, page
95) defines that LBA is always based on the logical block size. It
means bdev_logical_block_size() (aka BLKSSZGET) for Linux.

This patch removes static sector size from EFI GPT parser.

The problem is reproducible with the latest GNU Parted:

 # modprobe scsi_debug dev_size_mb=50 sector_size=4096

  # ./parted /dev/sdb print
  Model: Linux scsi_debug (scsi)
  Disk /dev/sdb: 52.4MB
  Sector size (logical/physical): 4096B/4096B
  Partition Table: gpt

  Number  Start   End     Size    File system  Name     Flags
   1      24.6kB  3002kB  2978kB               primary

   3      6001kB  9003kB  3002kB               primary

  # blockdev --rereadpt /dev/sdb
  # dmesg | tail -1

6f8de29a8e partitions: read whole sector with EFI GPT header
commit 87038c2d5b upstream.

The size of EFI GPT header is not static, but whole sector is
allocated for the header. The HeaderSize field must be greater
than 92 (= sizeof(struct gpt_header) and must be less than or
equal to the logical block size.

It means we have to read whole sector with the header, because the
header crc32 checksum is calculated according to HeaderSize.

For more details see UEFI standard (version 2.3, May 2009):

  - Table 13. GUID Partition Table Header, page 96

8f2fefcddf netfilter: xtables: fix conntrack match v1 ipt-save output
commit 3a0429292d upstream.

commit d6d3f08b0f
(netfilter: xtables: conntrack match revision 2) does break the
v1 conntrack match iptables-save output in a subtle way.

Problem is as follows:

    up = kmalloc(sizeof(*up), GFP_KERNEL);
[..]
   /*
    * The strategy here is to minimize the overhead of v1 matching,
    * by prebuilding a v2 struct and putting the pointer into the
    * v1 dataspace.
    */
    memcpy(up, info, offsetof(typeof(*info), state_mask));
[..]
    *(void **)info  = up;

As the v2 struct pointer is saved in the match data space,
it clobbers the first structure member (->origsrc_addr).

Because the _v1 match function grabs this pointer and does not actually
look at the v1 origsrc, run time functionality does not break.
But iptables -nvL (or iptables-save) cannot know that v1 origsrc_addr
has been overloaded in this way:

$ iptables -p tcp -A OUTPUT -m conntrack --ctorigsrc 10.0.0.1 -j ACCEPT
$ iptables-save
-A OUTPUT -p tcp -m conntrack --ctorigsrc 128.173.134.206 -j ACCEPT

(128.173... is the address to the v2 match structure).

To fix this, we take advantage of the fact that the v1 and v2 structures
are identical with exception of the last two structure members (u8 in v1,
u16 in v2).

We extract them as early as possible and prevent the v2 matching function
from looking at those two members directly.
