Tssk. Apparently Al hadn't checked commit c52c2ddc1dfa ("alpha: switch
osf_sigprocmask() to use of sigprocmask()") at all. It doesn't compile.
Fixed as per suggestions from Michael Cree.

ahci: fix module refcount breakage introduced by libahci split

libata depends on scsi_host_template for module reference counting and
sht's should be owned by each low level driver. During libahci split,
the sht was left with libahci.ko leaving the actual low level drivers
not reference counted. This made ahci and ahci_platform always
unloadable even while they're being actively used.
Fix it by defining AHCI_SHT() macro in ahci.h and defining a sht for
each low level ahci driver.
stable: only applicable to 2.6.35.

Commit e40cc4bdfd4b89813f072f72bd9c7055814d3f0f introduced
a build breakage if CONFIG_SMP is undefined. This commit
fixes the problem.
This fix is only a workaround. For a real fix, cpu_sibling_mask() should
be defined in UP include code, eg in linux/smp.h, and asm/smp.h should not be
included directly. This fix is currently not possible because asm/smp.h defines
cpu_sibling_mask() unconditionally and is included directly from many source
files.

Fixes kernel bugzilla #16603
tcp_sendmsg() truncates iov_len to an 'int' which a 4GB write to write
zero bytes, for example.
There is also the problem higher up of how verify_iovec() works. It
wants to prevent the total length from looking like an error return
value.
However it does this using 'int', but syscalls return 'long' (and
thus signed 64-bit on 64-bit machines). So it could trigger
false-positives on 64-bit as written. So fix it to use 'long'.

p9_virtio_create will only compare the the channel's tag characters
against the device name till the end of the channel's tag but not till
the end of the device name. This means that if a user defines channels
with the tags foo and foobar then he would mount foo when he requested
foonot and may mount foo when he requested foobar.
Thus it is necessary to check both string lengths against each other in
case of a successful partial string match.

When the interface is up, using ethtool breaks it because:
a) link is put down but media_timer interval is not shortened to NO_LINK
b) rxtx is stopped but not restarted
Also manual 10baseT-HD (and probably FD too - untested) mode does not work -
the link is forced up, packets are transmitted but nothing is received.
Changing CSR14 value to match documentation (not disabling link check) fixes this.

When TCP uses FACK algorithm to mark lost packets in
tcp_mark_head_lost(), if the number of packets in the (TSO) skb is
greater than the number of packets that should be marked lost, TCP
incorrectly exits the loop and marks no packets lost in the skb. This
underestimates tp->lost_out and affects the recovery/retransmission.
This patch fargments the skb and marks the correct amount of packets
lost.

This patch (commit 690a1f2002a3091bd18a501f46c9530f10481463) added a
new call site for acpi_set_WOL() without checking that the function is
actually suitable to be called via
vortex_set_wol+0xcd/0xe0 [3c59x]
dev_ethtool+0xa5a/0xb70
dev_ioctl+0x2e0/0x4b0
T.961+0x49/0x50
sock_ioctl+0x47/0x290
do_vfs_ioctl+0x7f/0x340
sys_ioctl+0x80/0xa0
system_call_fastpath+0x16/0x1b
i.e. outside of code paths run when the device is not yet enabled or
already disabled. In particular, putting the device into D3hot is a
pretty bad idea when it was already brought up.
Furthermore, all prior callers of the function made sure they're
actually dealing with a PCI device, while the newly added one didn't.
In the same spirit, the .get_wol handler shouldn't indicate support
for WOL for non-PCI devices.

Clean up a missing exit path in the ipv6 module init routines. In
addrconf_init we call ipv6_addr_label_init which calls register_pernet_subsys
for the ipv6_addr_label_ops structure. But if module loading fails, or if the
ipv6 module is removed, there is no corresponding unregister_pernet_subsys call,
which leaves a now-bogus address on the pernet_list, leading to oopses in
subsequent registrations. This patch cleans up both the failed load path and
the unload path. Tested by myself with good results.

Compex FreedomLine 32 PnP-PCI2 cards have only TP and BNC connectors but the
SROM contains AUI port too. When TP loses link, the driver switches to
non-existing AUI port (which reports that carrier is always present).
Connecting TP back generates LinkPass interrupt but de_media_interrupt() is
broken - it only updates the link state of currently connected media, ignoring
the fact that LinkPass and LinkFail bits of MacStatus register belong to the
TP port only (the chip documentation says that).
This patch changes de_media_interrupt() to switch media to TP when link goes
up (and media type is not locked) and also to update the link state only when
the TP port is used.
Also the NonselPortActive (and also SelPortActive) bits of SIAStatus register
need to be cleared (by writing 1) after reading or they're useless.

At least my 21041 cards come out of suspend with bus mastering disabled so
they did not work after resume(no data transferred).
After adding pci_set_master(), the driver oopsed immediately on resume -
because de_clean_rings() is called on suspend but de_init_rings() call
was missing in resume.
Also disable link (reset SIA) before sleep (de4x5 does this too).

At least on older 21041-AA chips (mine is rev. 11), TP duplex autonegotiation
causes the card not to work at all (link is up but no packets are transmitted).
de4x5 disables autonegotiation completely. But it seems to work on newer
(21041-PA rev. 21) so disable it only on rev<20 chips.

We have for each socket :
One spinlock (sk_slock.slock)
One rwlock (sk_callback_lock)
Possible scenarios are :
(A) (this is used in net/sunrpc/xprtsock.c)
read_lock(&sk->sk_callback_lock) (without blocking BH)
<BH>
spin_lock(&sk->sk_slock.slock);
...
read_lock(&sk->sk_callback_lock);
...
(B)
write_lock_bh(&sk->sk_callback_lock)
stuff
write_unlock_bh(&sk->sk_callback_lock)
(C)
spin_lock_bh(&sk->sk_slock)
...
write_lock_bh(&sk->sk_callback_lock)
stuff
write_unlock_bh(&sk->sk_callback_lock)
spin_unlock_bh(&sk->sk_slock)
This (C) case conflicts with (A) :
CPU1 [A] CPU2 [C]
read_lock(callback_lock)
<BH> spin_lock_bh(slock)
<wait to spin_lock(slock)>
<wait to write_lock_bh(callback_lock)>
We have one problematic (C) use case in inet_csk_listen_stop() :
local_bh_disable();
bh_lock_sock(child); // spin_lock_bh(&sk->sk_slock)
WARN_ON(sock_owned_by_user(child));
...
sock_orphan(child); // write_lock_bh(&sk->sk_callback_lock)
lockdep is not happy with this, as reported by Tetsuo Handa
It seems only way to deal with this is to use read_lock_bh(callbacklock)
everywhere.
Thanks to Jarek for pointing a bug in my first attempt and suggesting
this solution.

For non-managed versions of 82579, set the bit that prevents the hardware
from automatically configuring the PHY after resets only when the driver
performs a reset, clear the bit after resets. This is so the hardware can
configure the PHY automatically when the part is reset in a manner that is
not controlled by the driver (e.g. in a virtual environment via PCI FLR)
otherwise the PHY will be mis-configured causing issues such as failing to
link at 1000Mbps.
For managed versions of 82579, keep the previous behavior since the
manageability firmware will handle the PHY configuration.

The subject workaround was causing CRC errors due to writing the wrong
register with updates of the RCTL register. It was also found that the
workaround function which modifies the RCTL register was being called in
the middle of a read-modify-write operation of the RCTL register, so the
function call has been moved appropriately. Lastly, jumbo frames must not
be allowed when CRC stripping is disabled by a module parameter because the
workaround requires the CRC be stripped.

On 82579, there is a hardware bug that can cause received packets to not
get transferred from the PHY to the MAC due to K1 (a power saving feature
of the PHY-MAC interconnect similar to ASPM L1). Since the MAC controls
the accounting of missed packets, these will go unnoticed. Workaround the
issue by setting the K1 beacon duration according to the link speed.

Two recent patches to cleanup the reset[1] and initial PHY configuration[2]
code paths for ICH/PCH devices inadvertently left out a 10msec delay and
device ID check respectively which are necessary for the 82566DC (device id
0x104b) to be configured properly, otherwise it will not get link.

Since the hardware is prevented from performing automatic PHY configuration
(the driver does it instead), the OEM_WRITE_ENABLE bit in the EXTCNF_CTRL
register will not get cleared preventing the SMBus address and the LED
configuration to be written to the PHY registers. On 82579, do not check
the OEM_WRITE_ENABLE bit.

When going to Sx, disable gigabit in PHY (e1000_oem_bits_config_ich8lan)
in addition to the MAC before configuring PHY wakeup otherwise the PHY
configuration writes might be missed. Also write the LED configuration
and SMBus address to the PHY registers (e1000_oem_bits_config_ich8lan and
e1000_write_smbus_addr, respectively). The reset is no longer needed
since re-auto-negotiation is forced in e1000_oem_bits_config_ich8lan and
leaving it in causes issues with auto-negotiating the link.

adapter->cmb.cmb is initialized when the device is opened and freed when
it's closed. Accessing it unconditionally during resume results either
in a crash (NULL pointer dereference, when the interface has not been
opened yet) or data corruption (when the interface has been used and
brought down adapter->cmb.cmb points to a deallocated memory area).

This patch reduces namespace pollution by moving the "struct net" declaration
out of the userspace-facing portion of linux/netlink.h. It has no impact on
the kernel.
(This came up because we have several C++ applications which use "net" as a
namespace name.)

we need to check proper socket type within ipv4_conntrack_defrag
function before referencing the nodefrag flag.
For example the tun driver receive path produces skbs with
AF_UNSPEC socket type, and so current code is causing unwanted
fragmented packets going out.

ip_route_me_harder can't create the route cache when the outdev is the same

__mkroute_input functions has this check:
1998 if (skb->protocol != htons(ETH_P_IP)) {
1999 /* Not IP (i.e. ARP). Do not create route, if it is
2000 * invalid for proxy arp. DNAT routes are always valid.
2001 *
2002 * Proxy arp feature have been extended to allow, ARP
2003 * replies back to the same interface, to support
2004 * Private VLAN switch technologies. See arp.c.
2005 */
2006 if (out_dev == in_dev &&
2007 IN_DEV_PROXY_ARP_PVLAN(in_dev) == 0) {
2008 err = -EINVAL;
2009 goto cleanup;
2010 }
2011 }
This patch gives the new skb a valid protocol to bypass this check. In order
to make ipt_REJECT work with bridges, you also need to enable ip_forward.
This patch also fixes a regression. When we used skb_copy_expand(), we
didn't have this issue stated above, as the protocol was properly set.

Special care should be taken when slow path is hit in ip_fragment() :
When walking through frags, we transfert truesize ownership from skb to
frags. Then if we hit a slow_path condition, we must undo this or risk
uncharging frags->truesize twice, and in the end, having negative socket
sk_wmem_alloc counter, or even freeing socket sooner than expected.
Many thanks to Nick Bowler, who provided a very clean bug report and
test program.
Thanks to Jarek for reviewing my first patch and providing a V2
While Nick bisection pointed to commit 2b85a34e911 (net: No more
expensive sock_hold()/sock_put() on each tx), underlying bug is older
(2.6.12-rc5)
A side effect is to extend work done in commit b2722b1c3a893e
(ip_fragment: also adjust skb->truesize for packets not owned by a
socket) to ipv6 as well.

When a driver doesn't fill the entire buffer, old
heap contents may remain, and if it also doesn't
update the length properly, this old heap content
will be copied back to userspace.
It is very unlikely that this happens in any of
the drivers using private ioctls since it would
show up as junk being reported by iwpriv, but it
seems better to be safe here, so use kzalloc.
