commit 5e472d077f upstream.
xid 0 was used as an indication of invalid xid before but now xid 0
can be used as a valid exchange i. This patch fixes the ddp completion
in fcp layer, i.e., in fc_fcp.c:fc_fcp_ddp_done() function, to make sure it
does not use xid 0 for indication of an invalid xid, instead, it now
uses use FC_XID_UNKNOWN for such indication.

commit 85b5893ca9 upstream.
A received Fibre Channel ELS PRLI request contains a bit that
indicates whether the remote port supports certain retry processing
sequences. The test for this bit was somehow coded to use multiply
instead of AND!
This case would apply only for target mode operation, and it is
unlikely to be noticed as an initiator.

In testing 2.6.31 on one of our ia64 platforms I've encountered a hang
due to the driver using hardware ATEs which are a limited resource.
This is because the driver does not set the dma consistent mask to

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.

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.

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.

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.

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.

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.

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.

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.
