2010-08-02netfilter: nf_conntrack_acct: use skb->len for accountingChangli Gao
use skb->len for accounting as xt_quota does. Since nf_conntrack works at the network layer, skb_network_offset should always returns ZERO. Signed-off-by: Changli Gao <xiaosuo@gmail.com> Signed-off-by: Patrick McHardy <kaber@trash.net>
2010-08-02netfilter: nf_nat: don't check if the tuple is unique when there isn't any ↵Changli Gao
other choice The tuple got from unique_tuple() doesn't need to be really unique, so the check for the unique tuple isn't necessary, when there isn't any other choice. Eliminating the unnecessary nf_nat_used_tuple() can save some CPU cycles too. Signed-off-by: Changli Gao <xiaosuo@gmail.com> Signed-off-by: Patrick McHardy <kaber@trash.net>
2010-08-02netfilter: nf_nat: make unique_tuple return voidChangli Gao
The only user of unique_tuple() get_unique_tuple() doesn't care about the return value of unique_tuple(), so make unique_tuple() return void (nothing). Signed-off-by: Changli Gao <xiaosuo@gmail.com> Signed-off-by: Patrick McHardy <kaber@trash.net>

IPVS was merged into the kernel quite a long time ago and has been seeing wide-spread production use for even longer. It seems appropriate for it to be no longer tagged as EXPERIMENTAL Signed-off-as: Simon Horman <horms@verge.net.au> Signed-off-by: Patrick McHardy <kaber@trash.net>
2010-08-02netfilter: nf_conntrack_extend: introduce __nf_ct_ext_exist()Changli Gao
some users of nf_ct_ext_exist() know ct->ext isn't NULL. For these users, the check for ct->ext isn't necessary, the function __nf_ct_ext_exist() can be used instead. the type of the return value of nf_ct_ext_exist() is changed to bool.

2010-07-31TI DaVinci EMAC: Fix incorrect reference to EMAC_CTRL registers.Sriram
The EMAC modules control registers vary as per the version of the EMAC module. EMAC_CTRL_EWCTL,EMAC_CTRL_EWINTTCNT are available only on EMAC_VERSION_1. The emac_dump_regs() function accesses these indiscriminately. This patch fixes the issue. Signed-off-by: Sriramakrishnan <srk@ti.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-07-31TI DaVinci EMAC: Fix asymmetric handling of packets in NAPI Poll function.Sriram
The current implementation of NAPI poll function in the driver does not service Rx packets, error condition even if a single Tx packet gets serviced in the napi poll call.

2010-07-31bonding: prevent sysfs from allowing arp monitoring with alb/tlbAndy Gospodarek
When using module options arp monitoring and balance-alb/balance-tlb are mutually exclusive options. Anytime balance-alb/balance-tlb are enabled mii monitoring is forced to 100ms if not set. When configuring via sysfs no checking is currently done. Handling these cases with sysfs has to be done a bit differently because we do not have all configuration information available at once. This patch will not allow a mode change to balance-alb/balance-tlb if arp_interval is already non-zero. It will also not allow the user to set a non-zero arp_interval value if the mode is already set to balance-alb/balance-tlb. They are still mutually exclusive on a first-come, first serve basis. Tested with initscripts on Fedora and manual setting via sysfs. Signed-off-by: Andy Gospodarek <gospo@redhat.com> Signed-off-by: Jay Vosburgh <fubar@us.ibm.com> Signed-off-by: David S.

2010-07-29iwlwifi: fix scan abortStanislaw Gruszka
Fix possible double priv->mutex lock introduced by commit a69b03e941abae00380fc6bc1877fb797a1b31e6 "iwlwifi: cancel scan watchdog in iwl_bg_abort_scan" . We can not call cancel_delayed_work_sync(&priv->scan_check) with priv->mutex locked because workqueue function iwl_bg_scan_check() take that lock internally. We do not need to synchronize when canceling priv->scan_check work. We can avoid races (sending double abort command or send no command at all) using STATUS_SCAN_ABORT bit. Moreover current iwl_bg_scan_check() code seems to be broken, as we should not send abort commands when currently aborting.

2010-07-28mac80211: inform drivers about the off-channel status on channel changesFelix Fietkau
For some drivers it can be useful to know whether the channel they're supposed to switch to is going to be used for short off-channel work or scanning, or whether the hardware is expected to stay on it for a while longer. This is important for various kinds of calibration work, which takes longer to complete and should keep some persistent state, even if the channel temporarily changes.

2010-07-28Revert "mac80211: fix sw scan bracketing"Luis R. Rodriguez
This reverts this commit. While in theory the change is correct the patch does not address current assumptions made by some drivers, one which is definitley affected is ath9k. Prior to this change the scan complete callback would be called after we returned to the home channel and configured the hardware RX filters. After this change we call the scan complete callback prior to both the hw config and the config filter. At least for ath9k this breaks quite a few assumptions on the callback, leading to disconnects to the AP after every scan making the driver pretty useless on STA mode. The goal behind this commit was to address the now understood spurious warnings from ath9k and mac80211_hwsim on scanning on two wiphys at the same time but we have now supressed these and will address this issue in the next kernel release. When fixing this for good next we must first review the other driver's dependence on this logic and perhaps consider removal of the scan complete callback all together.

2010-07-28ath9k: remove the two wiphys scanning at the same time messageLuis R. Rodriguez
When issuing two consecutive scans you could often end up getting in the logs: "ath9k: Two wiphys trying to scan at the same time" This message is due to a race in mac80211 but addressing that race requires some more major changes on the driver and perhaps optimizations on mac80211 like removing the scan complete callback alltogether. Its too late to address this this kernel release so supress the complaint and annotate this needs fixing for later. Cc: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Luis R.
