Byte Queue Limits, from Hiroaki SHIMODA, Denys Fedoryshchenko, and Jesse Brandeburg. 5) Fix IPV6 crashes in packet generator module, from Amerigo Wang. 6) Tidies and fixes in the new VXLAN driver from Stephen Hemminger. 7) Bridge IP options parse doesn't check first if SKB header has at least an IP header's worth of content present. Fix from Sarveshwar Bandi. 8) The kernel now generates compound pages on transmit and the Xen netback drivers needs some adjustments in order to handle this. Fix from Ian Campbell. 9) Turn off ASPM in JME driver, from Kevin Bardon and Matthew Garrett. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (43 commits) mcs7830: Fix link state detection net: add doc for in4_pton() net: add doc for in6_pton() vti: fix sparse bit endian warnings tcp: resets are misrouted usbnet: Support devices reporting idleness Add CDC-ACM support for the CX93010-2x UCMxx USB Modem net/ethernet/jme: disable ASPM tcp: sysctl interface leaks 16 bytes of kernel memory kaweth: print correct debug ptr e1000e: Change wthresh to 1 to avoid possible Tx stalls ipv4: fix route mark sparse warning xen: netback: handle compound page fragments on transmit. bridge: Pull ip header into skb->data before looking into ip header. isdn: fix a wrapping bug in isdn_ppp_ioctl() vxlan: fix oops when give unknown ifindex vxlan: fix receive checksum handling vxlan: add additional headroom vxlan: allow configuring port range vxlan: associate with tunnel socket on transmit ...
| * mcs7830: Fix link state detectionOndrej Zary2012-10-121-9/+21
| | | | | | | | | | | | | | | | | | | | | | | | The device had an undocumented "feature": it can provide a sequence of spurious link-down status data even if the link is up all the time. A sequence of 10 was seen so update the link state only after the device reports the same link state 20 times.

| * tcp: resets are misroutedAlexey Kuznetsov2012-10-122-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After commit e2446eaa ("tcp_v4_send_reset: binding oif to iif in no sock case").. tcp resets are always lost, when routing is asymmetric. Yes, backing out that patch will result in misrouting of resets for dead connections which used interface binding when were alive, but we actually cannot do anything here. What's died that's died and correct handling normal unbound connections is obviously a priority. Comment to comment: > This has few benefits: > 1. tcp_v6_send_reset already did that. It was done to route resets for IPv6 link local addresses. It was a mistake to do so for global addresses. The patch fixes this as well. Actually, the problem appears to be even more serious than guaranteed loss of resets. As reported by Sergey Soloviev <sol@eqv.ru>, those misrouted resets create a lot of arp traffic and huge amount of unresolved arp entires putting down to knees NAT firewalls which use asymmetric routing.

Denys Fedoryshchenko and others reported Tx stalls on e1000e with BQL enabled. Issue was root caused to hardware delays. They were introduced because some of the e1000e hardware with transmit writeback bursting enabled, waits until the driver does an explict flush OR there are WTHRESH descriptors to write back. Sometimes the delays in question were on the order of seconds, causing visible lag for ssh sessions and unacceptable tx completion latency, especially for BQL enabled kernels. To avoid possible Tx stalls, change WTHRESH back to 1. The current plan is to investigate a method for re-enabling WTHRESH while not harming BQL, but those patches will be later for net-next if they work. please enqueue for stable since v3.3 as this bug was introduced in commit 3f0cfa3bc11e7f00c9994e0f469cbc0e7da7b00c Author: Tom Herbert <therbert@google.com> Date: Mon Nov 28 16:33:16 2011 +0000 e1000e: Support for byte queue limits Changes to e1000e to use byte queue limits.

| | * | mwifiex: update cfg80211 with correct reason code when connection is lostAmitkumar Karwar2012-10-084-16/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Driver gets LINK_LOST, DEAUTHENTICATED and DISASSOCIATED events from firmware when connection is lost in different scenarios. Currently we are using common code WLAN_REASON_DEAUTH_LEAVING for these cases. This patch adds support to parse an actual reason code from firmware event body and send it to cfg80211. WLAN_REASON_DEAUTH_LEAVING code is used if deauth is initiated by our device. Signed-off-by: Amitkumar Karwar <akarwar@marvell.com> Signed-off-by: Bing Zhao <bzhao@marvell.com> Signed-off-by: John W.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support to send correct reason code got from firmware when association attempt fails. Also, the error message displayed for association failure due to network incompatibility is modified. Current message "cannot find ssid.." misleads user.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | scan_processing flag should be reset when scan request is failed due to some reasons Ex. memory allocation failure etc. Otherwise further scan requests will be blocked.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are cases we cannot scan when request is received. For example, during WPA group key negociation the scan request will be blocked. We should return an error code to cfg80211 because cfg80211_scan_done will never be called.

| | * | mac80211: call drv_get_tsf() in sleepable contextThomas Pedersen2012-10-081-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The call to drv_get/set_tsf() was put on the workqueue to perform tsf adjustments since that function might sleep. However it ended up inside a spinlock, whose critical section must be atomic. Do tsf adjustment outside the spinlock instead, and get rid of a warning.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ensure that drv_start() always returns true, as a failing hw start usually eventually leads to crashes when there's still a station entry present. Call a power-on reset after a resume and after a hw reset failure to bring the hardware back to life again. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.

Pad out to 64-bytes. Make string reporting cleaner and easier to extend in the future using "const char *" arrays that index by either bit position, or absolute field value. Report the raw 64-byte error report as a sequence of u64s before the annotated version. Only report fields which are valid, given the context and the attribute bits which are set. For shutdown requests, use the local copy of the error report not the one we just freed up back to the queue. Also, use orderly_poweroff() just like the Domain Services shutdown request code does. If the real-address reported is "-1" (unknown) try to disassemble the instruction to report the effective address of the access. Only do this in privileged mode. Signed-off-by: David S.
