8 years agotg3: Do not call device_set_wakeup_enable() under spin_lock_bh
Rafael J. Wysocki [Mon, 25 Oct 2010 13:01:55 +0000]
tg3: Do not call device_set_wakeup_enable() under spin_lock_bh

The tg3 driver calls device_set_wakeup_enable() under spin_lock_bh,
which causes a problem to happen after the recent core power
management changes, because this function can sleep now.  Fix this
by moving the device_set_wakeup_enable() call out of the
spin_lock_bh-protected area.

netfilter: fix module dependency issues with IPv6 defragmentation, ip6tables and xt_TPROXY

One of the previous tproxy related patches split IPv6 defragmentation and
connection tracking, but did not correctly add Kconfig stanzas to handle the
new dependencies correctly. This patch fixes that by making the config options
mirror the setup we have for IPv4: a distinct config option for defragmentation
that is automatically selected by both connection tracking and
xt_TPROXY/xt_socket.

The patch also changes the #ifdefs enclosing IPv6 specific code in xt_socket
and xt_TPROXY: we only compile these in case we have ip6tables support enabled.

Joshua Hoke [Mon, 25 Oct 2010 01:44:22 +0000]
macb: Don't re-enable interrupts while in polling mode

On a busy network, the macb driver could get stuck in the interrupt
handler, quickly triggering the watchdog, due to a confluence of
factors:

 1. macb_poll re-enables interrupts unconditionally, even when it will
    be called again because it exhausted its rx budget

 2. macb_interrupt only disables interrupts after scheduling
    macb_poll, but scheduling fails when macb_poll is already scheduled
    because it didn't call napi_complete

 3. macb_interrupt loops until the interrupt status register is clear,
    which will never happen in this case if the driver doesn't disable
    the RX interrupt

Since macb_interrupt runs in interrupt context, this effectively locks
up the machine, triggering the hardware watchdog.

This issue was readily reproducible on a flooded network with a
modified 2.6.27.48 kernel. The same problem appears to still be in the
2.6.36-rc8 driver code, so I am submitting this patch against that
version. I have not tested this version of the patch except to make
sure the kernel compiles.

ath9k_hw: Fix TX carrier leakage for IEEE compliance on AR9003 2.2

This updates the initvals for the AR9003 2.2 chipsets. The initvals
are the initial register values we use for our registers upon hardware
reset. This synchs up the initvals to match what our latest recommendation
from our systems engineering team.

The description of changes in this update:

        Improves ability to support very strong Rx conditions.
        Enhances DFS support for AP-mode.
        Improves performance of Tx carrier leak calibration.
        Adds support for Japan channel 14 Tx filtering requirements.
        Improves Tx power accuracy.

Impact:

        Update required to address degraded throughput at very short range.
        Update required for AP-mode DFS certification.
        Update required to comply to IEEE Tx carrier leak specification.
        May not meet expected +/- 2 dB Tx power accuracy without update.

The most important fix here would be the TX carrier leakage required
to comply with IEEE 802.11 specifications. The group of changes have
been tested all together in one release.

8 years agocfg80211: fix regression on processing country IEs
Luis R. Rodriguez [Tue, 19 Oct 2010 00:44:51 +0000]
cfg80211: fix regression on processing country IEs

The patch 4f366c5:

wireless: only use alpha2 regulatory information from country IE

removed some complex intersection we were always doing between the AP's
country IE info and what we got from CRDA. When CRDA sent us back a
regulatory domain we would do some sanity checks on that regulatory
domain response we just got. Part of these sanity checks included
checking that we already had performed an intersection for the
request of NL80211_REGDOM_SET_BY_COUNTRY_IE type.

This mean that cfg80211 was only processing country IEs for cases
where we already had an intersection, but since we removed enforcing
this this is no longer required, we should just apply the country
IE country hint with the data received from CRDA.

This patch has fixes intended for kernels >= 2.6.36.

carl9170: fix memory leak issue in async cmd macro wrappers

This patch continues where the previous commit:
"carl9170: fix async command buffer leak"
left off.

Similar to carl9170_reboot/carl9170_powersave, the
carl9170_async_regwrite* macros would leak the
temporary command buffer, if __carl9170_exec_cmd

mac80211: don't sanitize invalid rates

I found this bug while poking around with a pure-gn AP.

Commit:
cfg80211/mac80211: Use more generic bitrate mask for rate control

Added some sanity checks to ensure that each tx rate index
is included in the configured mask and it would change any
rate indexes if it wasn't.

But, the current implementation doesn't take into account
that the invalid rate index "-1" has a special meaning
(= no further attempts) and it should not be "changed".

netlink: fix netlink_change_ngroups()

commit 6c04bb18ddd633 (netlink: use call_rcu for netlink_change_ngroups)
used a somewhat convoluted and racy way to perform call_rcu().

The old block of memory is freed after a grace period, but the rcu_head
used to track it is located in new block.

This can clash if we call two times or more netlink_change_ngroups(),
and a block is freed before another. call_rcu() called on different cpus
makes no guarantee in order of callbacks.

Fix this using a more standard way of handling this : Each block of
memory contains its own rcu_head, so that no 'use after free' can
happens.

can: at91_can: fix reception of extended frames

The AT91_MID_MIDE bit must be set in order to receive extended frames.
The reception of an extended frame sets this bit, while reception of
standard frames resets it. This results in some lost extended frames in
an extended ID only environment. But leads to unpredictable lost
extended ID frames in a mixed environment.

The problem is fixed by setting the AT91_MID_MIDE after reception of a
CAN frame.

connector: remove lazy workqueue creation

Commit 1a5645bc (connector: create connector workqueue only while
needed once) implements lazy workqueue creation for connector
workqueue.  With cmwq now in place, lazy workqueue creation doesn't
make much sense while adding a lot of complexity.  Remove it and
allocate an ordered workqueue during initialization.

This also removes a call to flush_scheduled_work() which is deprecated
and scheduled to be removed.

i2c-viapro: Don't log nacks

Transactions not acked can happen every now and then, in particular
during device detection, and various transaction types can be used for
this purpose. So stop logging this event, except when debugging is
enabled. This is what other similar drivers (e.g. i2c-i801 or
i2c-piix4) do.

The underlying I2C adapter may or may not be present when this driver
gets initialized, and may disappear later, so there is no safe time at
which the probe and remove functions can be discarded.

i2c-amd8111: Add proper error handling

The functions the functions amd_ec_wait_write and amd_ec_wait_read have an
unsigned return type, but return a negative constant to indicate an error
condition.

A sematic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@exists@
identifier f;
constant C;
@@

 unsigned f(...)
 { <+...
*  return -C;
 ...+> }
// </smpl>

Fixing amd_ec_wait_write and amd_ec_wait_read leads to the need to adjust
the return type of the functions amd_ec_write and amd_ec_read, which are
the only functions that call amd_ec_wait_write and amd_ec_wait_read.
amd_ec_write and amd_ec_read, in turn, are only called from within the
function amd8111_access, which already returns a signed typed value.  Each
of the calls to amd_ec_write and amd_ec_read are updated using the
following semantic patch:

// <smpl>
@@
@@

+ status = amd_ec_write
- amd_ec_write
  (...);
+ if (status) return status;

@@
@@

+ status = amd_ec_read
- amd_ec_read
  (...);
+ if (status) return status;
// </smpl>

The patch also adds the declaration of the status variable.

i2c: Fix Kconfig dependencies

drivers/i2c/algos/Kconfig makes all the algorithms dependent on
!I2C_HELPER_AUTO, which triggers a Kconfig warning about broken
dependencies when some driver selects one of the algorithms. Ideally
we would make only the prompts dependent on !I2C_HELPER_AUTO, however
Kconfig doesn't currently support that. So we have to redefine the
symbols separately for the I2C_HELPER_AUTO=y case.
