xen-netback: fix refcnt unbalance for 3.10

2013-12-04T18:57:36Z

With the introduction of "xen-netback: Don't destroy the netdev until the vif is shut down" (upstream commit id 279f438e36), vif disconnect and free are separated. However in the backported version reference counting code was not correctly modified, and the reset of vif->irq was lost. If frontend goes through vif life cycle more than once the reference counting is skewed. This patch adds back the missing vif->irq reset line. It also moves several lines of the reference counting code to vif_free, so the moved code corresponds to the counterpart in vif_alloc, thus the reference counting is balanced.

iwl4965: better skb management in rx path

2013-12-04T18:57:36Z

commit c1de4a9557d9e25e41fc4ba034b9659152205539 upstream. 4965 version of Eric patch "iwl3945: better skb management in rx path". It fixes several problems : 1) skb->truesize is underestimated. We really consume PAGE_SIZE bytes for a fragment, not the frame length. 2) 128 bytes of initial headroom is a bit low and forces reallocations. 3) We can avoid consuming a full page for small enough frames.

iwl3945: better skb management in rx path

2013-12-04T18:57:36Z

commit 45fe142cefa864b685615bcb930159f6749c3667 upstream. Steinar reported reallocations of skb->head with IPv6, leading to a warning in skb_try_coalesce() It turns out iwl3945 has several problems : 1) skb->truesize is underestimated. We really consume PAGE_SIZE bytes for a fragment, not the frame length. 2) 128 bytes of initial headroom is a bit low and forces reallocations. 3) We can avoid consuming a full page for small enough frames.

commit b43ea8068d2090cb1e44632c8a938ab40d2c7419 upstream. Patch to make TeVii S471 cards use the ts2020 tuner, since ds3000 driver no longer contains tuning code. Signed-off-by: Johannes Koch Signed-off-by: Mauro Carvalho Chehab Signed-off-by: Greg Kroah-Hartman

netfilter: nf_conntrack: use RCU safe kfree for conntrack extensions

2013-12-04T18:57:35Z

commit c13a84a830a208fb3443628773c8ca0557773cc7 upstream. Commit 68b80f11 (netfilter: nf_nat: fix RCU races) introduced RCU protection for freeing extension data when reallocation moves them to a new location. We need the same protection when freeing them in nf_ct_ext_free() in order to prevent a use-after-free by other threads referencing a NAT extension data via bysource list.

iwlwifi: don't WARN on host commands sent when firmware is dead

2013-12-04T18:57:35Z

commit 8ca95995e64f5d270889badb3e449dca91106a2b upstream. This triggers automatic bug reports and add no valuable information. Print a simple error instead and drop the host command. Signed-off-by: Emmanuel Grumbach Signed-off-by: Johannes Berg Signed-off-by: Greg Kroah-Hartman

drm/radeon: re-enable sw ACR support on pre-DCE4

2013-12-04T18:57:35Z

commit b852c985010a77c850b7548d64bbb964ca462b02 upstream. HW ACR support may have issues on some older chips, so use SW ACR for now until we've tested further. Signed-off-by: Alex Deucher CC: Rafał Miłecki Signed-off-by: Greg Kroah-Hartman

drm/radeon: use hw generated CTS/N values for audio

2013-12-04T18:57:35Z

commit ee0fec312a1c4e26f255955da942562cd8908a4b upstream. Use the hw generated values rather than calculating them in the driver. There may be some older r6xx asics where this doesn't work correctly. This remains to be seen. See bug: https://bugs.freedesktop.org/show_bug.cgi?id=69675 Signed-off-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman

drm/radeon: fix N/CTS clock matching for audio

2013-12-04T18:57:35Z

commit e7d12c2f98ae1e68c7298e5028048d150fa553a1 upstream. The drm code that calculates the 1001 clocks rounds up rather than truncating. This allows the table to match properly on those modes.
