r8169: Fix runtime power management
I noticed that one of the post-2.6.36 patches broke runtime PM of the
r8169 on my MSI Wind test machine in such a way that the link was not
brought up after reconnecting the network cable.
In the process of debugging the issue I realized that we only should
invoke the runtime PM functions in rtl8169_check_link_status() when
link change is reported and if we do so, the problem goes away.
Moreover, this allows rtl8169_runtime_idle() to be simplified quite
a bit.

net: Convert netpoll blocking api in bonding driver to be a counter
A while back I made some changes to enable netpoll in the bonding driver. Among
them was a per-cpu flag that indicated we were in a path that held locks which
could cause the netpoll path to block in during tx, and as such the tx path
should queue the frame for later use. This appears to have given rise to a
regression. If one of those paths on which we hold the per-cpu flag yields the
cpu, its possible for us to come back on a different cpu, leading to us clearing
a different flag than we set. This results in odd netpoll drops, and BUG
backtraces appearing in the log, as we check to make sure that we only clear set
bits, and only set clear bits. I had though briefly about changing the
offending paths so that they wouldn't sleep, but looking at my origional work
more closely, it doesn't appear that a per-cpu flag is warranted. We alrady
gate the checking of this flag on IFF_IN_NETPOLL, so we don't hit this in the
normal tx case anyway. And practically speaking, the normal use case for
netpoll is to only have one client anyway, so we're not going to erroneously
queue netpoll frames when its actually safe to do so. As such, lets just
convert that per-cpu flag to an atomic counter. It fixes the rescheduling bugs,
is equivalent from a performance perspective and actually eliminates some code
in the process.

refcount imbalance in llc_ui_bind(), because dev_getbyhwaddr() doesnt
take a reference on device, while dev_get_by_index() does.

^^ the group-address flag is set!
(the correct SA/TA would be: 00:1f:31:f8:64:ff)
Since the AP does not know from where the frames come, it
generates a DEAUTH response for the (invalid) mcast address.
This mcast deauth frame then passes through all filters and
tricks the stack into thinking that the AP brutally kicked
us!
This patch fixes the problem by simply ignoring
non-broadcast, group-addressed deauth/disassoc frames.

mac80211: Fix frame injection using non-AP vif
In order for frame injection to work properly for some use cases
(e.g., finding the station entry and keys for encryption), mac80211
needs to find the correct sdata entry. This works when the main vif
is in AP mode, but commit
a2c1e3dad516618cb0fbfb1a62c36d0b0744573a
broke this particular use case for station main vif. While this type of
injection is quite unusual operation, it has some uses and we should fix
it. Do this by changing the monitor vif sdata selection to allow station
vif to be selected instead of limiting it to just AP vifs. We still need
to skip some iftypes to avoid selecting unsuitable vif for injection.

Add a recursion_level to unix socket, allowing up to 4 levels.

inet sockets corresponding to passive connections are added to the bind hash

__inet_put_port() decrements hashinfo->bsockets and tb->num_owners, whereas

My analysis is we can eat all LOWMEM memory before unix_gc() being

unix_gc() can consume huge amount of time to perform cleanup because of
huge working set.
One way to handle this is to have a sensible limit on unix_tot_inflight,
tested from wait_for_unix_gc() and to force a call to unix_gc() if this
limit is hit.
This solves the OOM and also reduce overall latencies, and should not

ath9k: fix timeout on stopping rx dma
It seems that using ath9k_hw_stoppcurecv to stop rx dma is not enough.
When it's time to stop DMA, the PCU is still busy, so the rx enable

Using ath9k_hw_abortpcurecv helps with getting rx stopped much faster,
with this change, I cannot reproduce the rx stop related WARN_ON anymore.

of/phylib: Use device tree properties to initialize Marvell PHYs.
Some aspects of PHY initialization are board dependent, things like
indicator LED connections and some clocking modes cannot be determined
by probing. The dev_flags element of struct phy_device can be used to
control these things if an appropriate value can be passed from the
Ethernet driver. We run into problems however if the PHY connections
are specified by the device tree. There is no way for the Ethernet
driver to know what flags it should pass.
If we are using the device tree, the struct phy_device will be
populated with the device tree node corresponding to the PHY, and we
can extract extra configuration information from there.
The next question is what should the format of that information be?
It is highly device specific, and the device tree representation
should not be tied to any arbitrary kernel defined constants. A
straight forward representation is just to specify the exact bits that
should be set using the "marvell,reg-init" property:
phy5: ethernet-phy@5 {
reg = <5>;
compatible = "marvell,88e1149r";
marvell,reg-init =
/* led[0]:1000, led[1]:100, led[2]:10, led[3]:tx */
<3 0x10 0 0x5777>, /* Reg 3,16 <- 0x5777 */
/* mix %:0, led[0123]:drive low off hiZ */
<3 0x11 0 0x00aa>, /* Reg 3,17 <- 0x00aa */
/* default blink periods. */
<3 0x12 0 0x4105>, /* Reg 3,18 <- 0x4105 */
/* led[4]:rx, led[5]:dplx, led[45]:drive low off hiZ */
<3 0x13 0 0x0a60>; /* Reg 3,19 <- 0x0a60 */
};
phy6: ethernet-phy@6 {
reg = <6>;
compatible = "marvell,
88e1118";
marvell,reg-init =
/* Fix rx and tx clock transition timing */
<2 0x15 0xffcf 0>, /* Reg 2,21 Clear bits 4, 5 */
/* Adjust LED drive. */
<3 0x11 0 0x442a>, /* Reg 3,17 <- 0442a */
/* irq, blink-activity, blink-link */
<3 0x10 0 0x0242>; /* Reg 3,16 <- 0x0242 */
};
The Marvell PHYs have a page select register at register 22 (0x16), we
can specify any register by its page and register number. These are
the first and second word. The third word contains a mask to be ANDed
with the existing register value, and the fourth word is ORed with the
result to yield the new register value. The new marvell_of_reg_init
function leaves the page select register unchanged, so a call to it
can be dropped into the .config_init functions without unduly
affecting the state of the PHY.
If CONFIG_OF_MDIO is not set, there is no of_node, or no
"marvell,reg-init" property, the PHY initialization is unchanged.

The fix is to set the driver's "down" flag later in the routine,
after all the timers and such have exited, preventing the interrupt
handler from being called and exiting early without handling the
interrupt.
