Jiri Slaby 6a20bd45fd NET: wan/x25, fix ldisc->open retval
We should never return positive values from ldisc->open, tty layer
doesn't (and never did) expect that.

If we do that, weird things like warnings in tty_ldisc_close happen.

Not sure if dev->base_addr is used somehow now.

For libertas_sdio this is a regression introduced by 23b149c189.

Yang Li d830418e40 ucc_geth: fix ucc halt problem in half duplex mode
In commit 58933c64(ucc_geth: Fix the wrong the Rx/Tx FIFO size),
the UCC_GETH_UTFTT_INIT is set to 512 based on the recommendation
of the QE Reference Manual.  But that will sometimes cause tx halt
while working in half duplex mode.

According to errata draft QE_GENERAL-A003(High Tx Virtual FIFO
threshold size can cause UCC to halt), setting UTFTT less than
[(UTFS x (M - 8)/M) - 128] will prevent this from happening
(M is the minimum buffer size).

The patch changes UTFTT back to 256.

We register lapb when tty is created, but unregister it only when the
device is UP. So move the lapb_unregister to x25_asy_close_tty after
the device is down.

The old behaviour causes ldisc switching to fail each second attempt,
because we noted for us that the device is unused, so we use it the
second time, but labp layer still have it registered, so it fails
obviously.

When it's time to stop DMA, the PCU is still busy, so the rx enable

David Daney cf41a51db8 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.

Driver is also passing debug as a bitmask into netif_msg_init()

change this to pass in -1 so the defaults get used instead,
which makes the default much less verbose.

VMWare reports that the e1000 driver has a bug when bringing down the
interface, such that interrupts are not disabled in the hardware but the
driver stops reporting that it consumed the interrupt.

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.

Sarveshwar Bandi d9efd2af46 be2net: Fix to avoid firmware update when interface is not open.
Since interrupts are enabled only when open is called on the interface,
Attempting a firmware update operation when interface is down could lead to
partial success or failure of operation. This fix fails the request if
netif_running is false.

Shan Wei 24b7ea9f6c 8139cp: fix checksum broken
I am not family with RealTek RTL-8139C+ series 10/100 PCI Ethernet driver.
I try to guess the meaning of RxProtoIP and IPFail.
RxProtoIP stands for received IPv4 packet that upper protocol is not tcp and udp.
!(status & IPFail) is true means that driver correctly to check checksum in IPv4 header.

If these are right, driver will set ip_summed with CHECKSUM_UNNECESSARY for other
upper protocol, e.g. sctp, igmp protocol. This will cause protocol stack ignores
checksum check for packets with invalid checksum.

This patch is only compile-test.

Currently the skb->protocol field is used to setup various
offloading parameters on transmit for the correct protocol.
However, if vlan offloading is disabled or otherwise not used,
the protocol field will be ETH_P_8021Q, not the actual protocol.
This will cause the offloading to be not performed correctly,
even though the hardware is capable of looking inside vlan tags.
Instead, look inside the header if necessary to determine the
correct protocol type.

To some extent this fixes a regression from 2.6.36 because it
was previously not possible to disable vlan offloading and this
error case was not exposed.

Johannes Berg 5ada28bf76 led-class: always implement blinking
Currently, blinking LEDs can be awkward because it is not guaranteed that
all LEDs implement blinking.  The trigger that wants it to blink then
needs to implement its own timer solution.

Rather than require that, add led_blink_set() API that triggers can use.
This function will attempt to use hw blinking, but if that fails
implements a timer for it.  To stop blinking again, brightness_set() also
needs to be wrapped into API that will stop the software blink.

As a result of this, the timer trigger becomes a very trivial one, and
hopefully we can finally see triggers using blinking as well because it's
always easy to use.

added aditional error checking against pipe types under CONFIG_USB_DEBUG.

So bmAttribute has to be updated for both EP3 & EP4 before submitting
urbs on that pipe. This patch resolves the following failure.

Vasanthakumar Thiagarajan f119da3015 ath9k_hw: Fix AR9280 surprise removal during frequent idle on/off
Bit 22 of AR_WA should be set to fix the situation where chip reset
is asynchronous to clock of analog shift registers, such that when
reset is released, it could mess up the values of analog shift registers
and cause some hw issue on AR9280.

This bit is write only, but the driver does a read-modify-write
on AR_WA without setting bit 22 in ar9002_hw_configpcipowersave()
during radio disable. This causes surprise removal of hw. It can
never recover from this state and the hw will become usable only
after a power on/off cycle, and sometimes only during a cold reboot.

This issue can be triggered by doing frequent roaming with the
simple/test-roam script available from the wifi-test project [1]
when roaming between APs quickly. When roaming there is a is a high
possibility that the device being put into idle (radio disable) state
by mac80211 during AUTH->ASSOC. A device hardware reset would fail
and the kernel would output:

This is currently only reproducible with some HB92 (Half Mini-PCIE)
cards but the fix applies to all AR9280 cards. This patch fixes this
issue by setting bit 22 during radio disable.

This patch has fixes for all kernels that has ath9k.

Linus Torvalds 269e2d77b8 libipw: fix proc entry removal
This bug seems to be due to commit 27ae60f8f7 ("ipw2x00: replace
"ieee80211" with "libipw" where appropriate"), where Pavel did this:

-       libipw_proc = proc_mkdir(DRV_NAME, init_net.proc_net);
+       libipw_proc = proc_mkdir("ieee80211", init_net.proc_net);

but then the cleanup was kept as

        remove_proc_entry(DRV_NAME, init_net.proc_net);

in both places (both in the failure case and in the unload case). The
error string is also total crap, and says

     "Unable to create " DRV_NAME " proc directory\n");

Even though it doesn't actually create a proc directory named DRV_NAME at all.

So that patch looks like total and utter crap to me. The commit message says

  "Keep /proc/net/ieee80211 under the original name to avoid breaking user
    interface."

but the thing is, it really didn't fix anything but that one create
thing. It needs to fix all the other cases too.

Linus Torvalds 151f52f09c ipw2x00: remove the right /proc/net entry
Commit 27ae60f8f7 ("ipw2x00: replace "ieee80211" with "libipw" where
appropriate") changed DRV_NAME to be "libipw", but didn't properly fix
up the places where it was used to specify the name for the /proc/net/
directory.

For backwards compatibility reasons, that directory name remained
"ieee80211", but due to the DRV_NAME change, the error case printouts
and the cleanup functions now used "libipw" instead.  Which made it all
fail badly.

For example, on module unload as reported by Randy:

  WARNING: at fs/proc/generic.c:816 remove_proc_entry+0x156/0x35e()
  name 'libipw'

because it's trying to unregister a /proc directory that obviously
doesn't even exist.

Clean it all up to use DRV_PROCNAME for the actual /proc directory name.
