2009-07-05net: use NETDEV_TX_OK instead of 0 in ndo_start_xmit() functionsPatrick McHardy
This patch is the result of an automatic spatch transformation to convert all ndo_start_xmit() return values of 0 to NETDEV_TX_OK. Some occurences are missed by the automatic conversion, those will be handled in a seperate patch. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

2009-06-02net_cls: fix unconfigured struct tcf_proto keeps chaining and avoid kernel ↵Minoru Usui
panic when we use cls_cgroup This patch fixes a bug which unconfigured struct tcf_proto keeps chaining in tc_ctl_tfilter(), and avoids kernel panic in cls_cgroup_classify() when we use cls_cgroup. When we execute 'tc filter add', tcf_proto is allocated, initialized by classifier's init(), and chained. After it's chained, tc_ctl_tfilter() calls classifier's change(). When classifier's change() fails, tc_ctl_tfilter() does not free and keeps tcf_proto. In addition, cls_cgroup is initialized in change() not in init(). It accesses unconfigured struct tcf_proto which is chained before change(), then hits Oops.

2009-05-25net: txq_trans_update() helperEric Dumazet
We would like to get rid of netdev->trans_start = jiffies; that about all net drivers have to use in their start_xmit() function, and use txq->trans_start instead. This can be done generically in core network, as suggested by David. Some devices, (particularly loopback) dont need trans_start update, because they dont have transmit watchdog. We could add a new device flag, or rely on fact that txq->tran_start can be updated is txq->xmit_lock_owner is different than -1. Use a helper function to hide our choice.

It is illegal to dereference a skb after a successful ndo_start_xmit() call. We must store skb length in a local variable instead.

2009-05-17net: tx scalability works : trans_startEric Dumazet
struct net_device trans_start field is a hot spot on SMP and high performance devices, particularly multi queues ones, because every transmitter dirties it. Is main use is tx watchdog and bonding alive checks. But as most devices dont use NETIF_F_LLTX, we have to lock a netdev_queue before calling their ndo_start_xmit(). So it makes sense to move trans_start from net_device to netdev_queue. Its update will occur on a already present (and in exclusive state) cache line, for free. We can do this transition smoothly. An old driver continue to update dev->trans_start, while an updated one updates txq->trans_start. Further patches could also put tx_bytes/tx_packets counters in netdev_queue to avoid dirtying dev->stats (vlan device comes to mind) Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S.

2009-04-20net: sch_netem: Fix an inconsistency in ingress netem timestamps.Jarek Poplawski
Alex Sidorenko reported: "while experimenting with 'netem' we have found some strange behaviour. It seemed that ingress delay as measured by 'ping' command shows up on some hosts but not on others. After some investigation I have found that the problem is that skbuff->tstamp field value depends on whether there are any packet sniffers enabled. That is: - if any ptype_all handler is registered, the tstamp field is as expected - if there are no ptype_all handlers, the tstamp field does not show the delay" This patch prevents unnecessary update of tstamp in dev_queue_xmit_nit() on ingress path (with act_mirred) adding a check, so minimal overhead on the fast path, but only when sniffers etc. are active. Since netem at ingress seems to logically emulate a network before a host, tstamp is zeroed to trigger the update and pretend delays are from the outside.

2009-03-15pkt_sched: Change misleading code in class delete.Jarek Poplawski
While looking for a possible reason of bugzilla report on HTB oops: http://bugzilla.kernel.org/show_bug.cgi?id=12858 I found the code in htb_delete calling htb_destroy_class on zero refcount is very misleading: it can suggest this is a common path, and destroy is called under sch_tree_lock. Actually, this can never happen like this because before deletion cops->get() is done, and after delete a class is still used by tclass_notify. The class destroy is always called from cops->put(), so without sch_tree_lock. This doesn't mean much now (since 2.6.27) because all vulnerable calls were moved from htb_destroy_class to htb_delete, but there was a bug in older kernels. The same change is done for other classful scheds, which, it seems, didn't have similar locking problems here.

2009-01-04net: Fix for initial link state in 2.6.28Michael Marineau
From: Michael Marineau <mike@marineau.org> Commit b47300168e770b60ab96c8924854c3b0eb4260eb "Do not fire linkwatch events until the device is registered." was made as a workaround for drivers that call netif_carrier_off before registering the device. Unfortunately this causes these drivers to incorrectly report their link status as IF_OPER_UNKNOWN which can falsely set the IFF_RUNNING flag when the interface is first brought up. This issues was previously pointed out[1] but was dismissed saying that IFF_RUNNING is not related to the link status. From my digging IFF_RUNNING, as reported to userspace, is based on the link state. It is set based on __LINK_STATE_START and IF_OPER_UP or IF_OPER_UNKNOWN. See [2], [3], and [4]. (Whether or not the kernel has IFF_RUNNING set in flags is not reported to user space so it may well be independent of the link, I don't know if and when it may get set.) The end result depends slightly depending on the driver. The the two I tested were e1000e and b44. With e1000e if the system is booted without a network cable attached the interface will falsely report RUNNING when it is brought up causing NetworkManager to attempt to start it and eventually time out. With b44 when the system is booted with a network cable attached and brought up with dhcpcd it will time out the first time. The attached patch that will still set the operstate variable correctly to IF_OPER_UP/DOWN/etc when linkwatch_fire_event is called but then return rather than skipping the linkwatch_fire_event call entirely as the previous fix did.
