* drivers/net/ixgbe/ixgbe_common.c: use %pM to show MAC addresshartleys2010-01-071-10/+2
| | | | | | | | | | | Use the %pM kernel extension to display the MAC address. The only difference in the output is that the MAC address is shown in the usual colon-separated hex notation.

* net: Make it easier to parse /proc/net/dev contents.Jesper Dangaard Brouer2010-01-071-1/+1
| | | | | | | | | | | | | | | | | | The contents of /proc/net/dev is annoying to parse, because it changes whether there is a space after the "ethX:" or not. It depends upon the size of the "Receive bytes" counter, if the number is below 7 digits, then there is whitespaces else if the number is 8 digits or above there is no space between the ":" and the number. This patch changes the output to assure there is always a space between the ":" and the number. Given that all existing userspace application already need to handle the whitespaces, I see no breakage of existing tools.

* net: RFC3069, private VLAN proxy arp supportJesper Dangaard Brouer2010-01-076-5/+76
| | | | | | | | | | | | | | | | | | | | | | | This is to be used together with switch technologies, like RFC3069, that where the individual ports are not allowed to communicate with each other, but they are allowed to talk to the upstream router. As described in RFC 3069, it is possible to allow these hosts to communicate through the upstream router by proxy_arp'ing. This patch basically allow proxy arp replies back to the same interface (from which the ARP request/solicitation was received). Tunable per device via proc "proxy_arp_pvlan": /proc/sys/net/ipv4/conf/*/proxy_arp_pvlan This switch technology is known by different vendor names: - In RFC 3069 it is called VLAN Aggregation. - Cisco and Allied Telesyn call it Private VLAN. - Hewlett-Packard call it Source-Port filtering or port-isolation. - Ericsson call it MAC-Forced Forwarding (RFC Draft).

The original change overloaded null_or_orig, but doing that prevented any packet handlers that were not tied to a specific device (i.e. ptype->dev == NULL) from ever receiving any frames. The null_or_orig variable cannot be overloaded, and must be kept as NULL to prevent the frame from being ignored by packet handlers designed to accept frames on any interface.

For suspend and resume this is important due to all the possible issues that can come out of the suspend <-> resume cycle. Not propagating the error means cfg80211 will assume the resume for the device went through fine and mac80211 will continue on trying to poke at the hardware, enable timers, queue work, and so on for a device which is completley unfunctional. The least we can do is to propagate device start issues and warn when this occurs upon resume. A side effect of this patch is we also now propagate the start errors upon harware reconfigurations (non-suspend), but this should also be desirable anyway, there is not point in continuing to reconfigure a device if mac80211 was unable to start the device.

If such calls are made, however, suspend can end up throwing hardware in an unexpected state and making the device unusable upon resume. Fix this by preventing mac80211 to schedule dynamic_ps_disable_work by checking for when mac80211 starts to suspend and starts quiescing. Frames should be allowed to go through though as that is part of the quiescing steps and we do not flush the mac80211 workqueue since it was already done towards the beginning of suspend cycle. The other mac80211 issue will be hanled in the next patch. For further details see refer to the thread: http://marc.info/?t=126144866100001&r=1&w=2 Cc: stable@kernel.org Signed-off-by: Luis R.

In that case, it may happen that mac80211 tries to report the assoc success to cfg80211, but gets blocked on the wdev lock that is held because the user is requesting the deauth. The result is that we run into a warning. This is mostly harmless, but maybe cause an unexpected event to be sent to userspace; we'd send an assoc success event although userspace was no longer expecting that. To fix this, remove the warning and check whether the race happened and in that case abort processing.

However, the calibration interval isn't initialized before interrupts are enabled, so we can have a situation where an interrupt occurs before the interval is assigned, so the interval is actually negative. As a result, the ISR will arm a software interrupt to schedule the tasklet, and then rearm it when the SWI is processed, and so on, leading to a softlockup at modprobe time. Move the initialization order around so the calibration interval is set before interrupts are active. Another possible fix is to schedule the tasklet directly from the poll routine, but I think there are additional plans for the SWI.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When fixed bssid is requested when joining an ibss network, incoming beacons that match the configured bssid cause mac80211 to create new sta entries, even before the ibss interface is in joined state. When that happens, it fails to bring up the interface entirely, because it checks for existing sta entries before joining. This patch fixes this bug by refusing to create sta info entries before the interface is fully operational. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.

At the same time, also document in mac80211.h the op functions with missing contexts. mac80211 doesn't seem to use get_tx_stats anywhere currently. Just to be on the safe side, I documented it to be atomic, but hopefully the op can be removed in the future. Compile-tested only.
