2012-01-20tcp: fix undo after RTO for CUBICNeal Cardwell
This patch fixes CUBIC so that cwnd reductions made during RTOs can be undone (just as they already can be undone when using the default/Reno behavior). When undoing cwnd reductions, BIC-derived congestion control modules were restoring the cwnd from last_max_cwnd. There were two problems with using last_max_cwnd to restore a cwnd during undo: (a) last_max_cwnd was set to 0 on state transitions into TCP_CA_Loss (by calling the module's reset() functions), so cwnd reductions from RTOs could not be undone. (b) when fast_covergence is enabled (which it is by default) last_max_cwnd does not actually hold the value of snd_cwnd before the loss; instead, it holds a scaled-down version of snd_cwnd. This patch makes the following changes: (1) upon undo, revert snd_cwnd to ca->loss_cwnd, which is already, as the existing comment notes, the "congestion window at last loss" (2) stop forgetting ca->loss_cwnd on TCP_CA_Loss events (3) use ca->last_max_cwnd to check if we're in slow start Signed-off-by: Neal Cardwell <ncardwell@google.com> Acked-by: Stephen Hemminger <shemminger@vyatta.com> Acked-by: Sangtae Ha <sangtae.ha@gmail.com> Signed-off-by: David S.

2012-01-18bonding: fix enslaving in alb mode when link downJiri Bohac
bond_alb_init_slave() is called from bond_enslave() and sets the slave's MAC address. This is done differently for TLB and ALB modes. bond->alb_info.rlb_enabled is used to discriminate between the two modes but this flag may be uninitialized if the slave is being enslaved prior to calling bond_open() -> bond_alb_initialize() on the master. It turns out all the callers of alb_set_slave_mac_addr() pass bond->alb_info.rlb_enabled as the hw parameter. This patch cleans up the unnecessary parameter of alb_set_slave_mac_addr() and makes the function decide based on the bonding mode instead, which fixes the above problem.

2012-01-18pch_gbe: Do not abort probe on bad MACDarren Hart
If the MAC is invalid or not implemented, do not abort the probe. Issue a warning and prevent bringing the interface up until a MAC is set manually (via ifconfig $IFACE hw ether $MAC). Tested on two platforms, one with a valid MAC, the other without a MAC. The real MAC is used if present, the interface fails to come up until the MAC is set on the other. They successfully get an IP over DHCP and pass a simple ping and login over ssh test. This is meant to allow the Inforce SYS940X development board: http://www.inforcecomputing.com/SYS940X_ECX.html (and others suffering from a missing MAC) to work with the mainline kernel. Without this patch, the probe will fail and the interface will not be created, preventing the user from configuring the MAC manually. This does not make any attempt to address a missing or invalid MAC for the pch_phub driver.

2012-01-18net: race condition in ipv6 forwarding and disable_ipv6 parametersFrancesco Ruggeri
There is a race condition in addrconf_sysctl_forward() and addrconf_sysctl_disable(). These functions change idev->cnf.forwarding (resp. idev->cnf.disable_ipv6) and then try to grab the rtnl lock before performing any actions. If that fails they restore the original value and restart the syscall. This creates race conditions if ipv6 code tries to access these parameters, or if multiple instances try to do the same operation. As an example of the former, if __ipv6_ifa_notify() finds a 0 in idev->cnf.forwarding when invoked by addrconf_ifdown() it may not free anycast addresses, ultimately resulting in the net_device not being freed. This patch reads the user parameters into a temporary location and only writes the actual parameters when the rtnl lock is acquired. Tested in 2.6.38.8.

Several problems fixed in this patch : 1) Target of the conditional jump in case a divide by 0 is performed by a bpf is wrong. 2) Must 'generate' the full function prologue/epilogue at pass=0, or else we can stop too early in pass=1 if the proglen doesnt change. (if the increase of prologue/epilogue equals decrease of all instructions length because some jumps are converted to near jumps) 3) Change the wrong length detection at the end of code generation to issue a more explicit message, no need for a full stack trace.

2012-01-18mac80211: fix work removal on deauth requestJohannes Berg
When deauth is requested while an auth or assoc work item is in progress, we currently delete it without regard for any state it might need to clean up. Fix it by cleaning up for those items. In the case Pontus found, the problem manifested itself as such: authenticate with 00:23:69:aa:dd:7b (try 1) authenticated failed to insert Dummy STA entry for the AP (error -17) deauthenticating from 00:23:69:aa:dd:7b by local choice (reason=2) It could also happen differently if the driver uses the tx_sync callback. We can't just call the ->done() method of the work items because that will lock up due to the locking in cfg80211. This fix isn't very clean, but that seems acceptable since I have patches pending to remove this code completely.

Use local->tx_headroom instad of local->hw.extra_tx_headroom. local->tx_headroom is the max of hw.extra_tx_headroom required by the driver and the headroom required by mac80211 for status reporting. On drivers where hw.extra_tx_headroom is smaller than what mac80211 requires (e.g. ath5k), we would not reserve sufficient buffer space to report tx status. Also, don't reserve local->tx_headroom + local->hw.extra_tx_headroom.

2012-01-17tg3: Fix single-vector MSI-X codeMatt Carlson
Kdump kernels leave MSI-X interrupts (as setup by the crashed kernel) enabled. However, kdump only enables one CPU in the new environment, thus causing tg3 to abort MSI-X setup. When the driver attempts to enable INTA or MSI interrupt modes on a kdump kernel, interrupt delivery fails. This patch attempts to workaround the problem by forcing the driver to enable a single MSI-X interrupt. In such a configuration, the device's multivector interrupt mode must be disabled.
