It looks like there's no need for those two fields: - Unless there's a failure for the first refill try, rq->max should be always equal to the vring size. - rq->num is only used to determine the condition that we need to do the refill, we could check vq->num_free instead. - rq->num was required to be increased or decreased explicitly after each get/put which results a bad API. So this patch removes them both to make the code simpler. Cc: Rusty Russell <rusty@rustcorp.com.au> Cc: Michael S. Tsirkin <mst@redhat.com> Signed-off-by:

Currently, if a slave's name change, we just pass it by. However, if the slave is a current primary_slave, then we end up with using a slave, whose name != params.primary, for primary_slave. And vice-versa, if we don't have a primary_slave but have params.primary set - we will not detected a new primary_slave. Fix this by catching the NETDEV_CHANGENAME event and setting primary_slave accordingly. Also, if the primary_slave was changed, issue a reselection of the active slave, cause the priorities have changed. Reported-by:

Now it catches the NETDEV_CHANGEMTU notification, which is signaled after the actual change happened on the device, and returns NOTIFY_BAD, so that the change on the device is reverted. This might be quite costly and messy, so use the new NETDEV_PRECHANGEMTU to catch the MTU change before the actual change happens and signal that it's forbidden to do it.

Currently, if a device changes its mtu, first the change happens (invloving all the side effects), and after that the NETDEV_CHANGEMTU is sent so that other devices can catch up with the new mtu. However, if they return NOTIFY_BAD, then the change is reverted and error returned. This is a really long and costy operation (sometimes). To fix this, add NETDEV_PRECHANGEMTU notification which is called prior to any change actually happening, and if any callee returns NOTIFY_BAD - the change is aborted. This way we're skipping all the playing with apply/revert the mtu. CC: "David S.

Ever since this driver was merged the following code was included: if (skb->len < MISR) skb->len = MISR; MISR is defined to 0x3C which is also equivalent to ETH_ZLEN, but use ETH_ZLEN directly which is exactly what we want to be checking for. Reported-by:

On newer and faster machines (Vortex X86DX) using the r6040 driver, it was noticed that the driver was returning an error during probing traced down to being the MDIO bus probing and the inability to complete a MDIO read operation in time. It turns out that the MDIO operations on these faster machines usually complete after ~2140 iterations which is bigger than 2048 (MAC_DEF_TIMEOUT) and results in spurious timeouts depending on the system load. Update r6040_phy_read() and r6040_phy_write() to include a 1 micro second delay in each busy-looping iteration of the loop which is a much safer operation than incrementing MAC_DEF_TIMEOUT.

When initializing a gro_list for a packet, first check the rxhash of the incoming skb against that of the skb's in the list. This should be a very strong inidicator of whether the flow is going to be matched, and potentially allows a lot of other checks to be short circuited. Use skb_hash_raw so that we don't force the hash to be calculated. Tested by running netperf 200 TCP_STREAMs between two machines with GRO, HW rxhash, and 1G. Saw no performance degration, slight reduction of time in dev_gro_receive. Signed-off-by:

In PF_PACKET's packet mmap(), we can avoid using one atomic_inc() and one atomic_dec() call in skb destructor and use a percpu reference count instead in order to determine if packets are still pending to be sent out. Micro-benchmark with [1] that has been slightly modified (that is, protcol = 0 in socket(2) and bind(2)), example on a rather crappy testing machine; I expect it to scale and have even better results on bigger machines: ./packet_mm_tx -s7000 -m7200 -z700000 em1, avg over 2500 runs: With patch: 4,022,015 cyc Without patch: 4,812,994 cyc time ./packet_mm_tx -s64 -c10000000 em1 > /dev/null, stable: With patch: real 1m32.241s user 0m0.287s sys 1m29.316s Without patch: real 1m38.386s user 0m0.265s sys 1m35.572s In function tpacket_snd(), it is okay to use packet_read_pending() since in fast-path we short-circuit the condition already with ph != NULL, since we have next frames to process. In case we have MSG_DONTWAIT, we also do not execute this path as need_wait is false here anyway, and in case of _no_ MSG_DONTWAIT flag, it is okay to call a packet_read_pending(), because when we ever reach that path, we're done processing outgoing frames anyway and only look if there are skbs still outstanding to be orphaned. We can stay lockless in this percpu counter since it's acceptable when we reach this path for the sum to be imprecise first, but we'll level out at 0 after all pending frames have reached the skb destructor eventually through tx reclaim. When people pin a tx process to particular CPUs, we expect overflows to happen in the reference counter as on one CPU we expect heavy increase; and distributed through ksoftirqd on all CPUs a decrease, for example. As David Laight points out, since the C language doesn't define the result of signed int overflow (i.e. rather than wrap, it is allowed to saturate as a possible outcome), we have to use unsigned int as reference count. The sum over all CPUs when tx is complete will result in 0 again. The BUG_ON() in tpacket_destruct_skb() we can remove as well. It can _only_ be set from inside tpacket_snd() path and we made sure to increase tx_ring.pending in any case before we called po->xmit(skb). So testing for tx_ring.pending == 0 is not too useful. Instead, it would rather have been useful to test if lower layers didn't orphan the skb so that we're missing ring slots being put back to TP_STATUS_AVAILABLE. But such a bug will be caught in user space already as we end up realizing that we do not have any TP_STATUS_AVAILABLE slots left anymore. Therefore, we're all set. Btw, in case of RX_RING path, we do not make use of the pending member, therefore we also don't need to use up any percpu memory here. Also note that __alloc_percpu() already returns a zero-filled percpu area, so initialization is done already. [1] http://wiki.ipxwarzone.com/index.php5?title=Linux_packet_mmapSigned-off-by:

In tpacket_snd(), when we've discovered a first frame that is not in status TP_STATUS_SEND_REQUEST, and return a NULL buffer, we exit the send routine in case of MSG_DONTWAIT, since we've finished traversing the mmaped send ring buffer and don't care about pending frames. While doing so, we still unconditionally call an expensive schedule() in the packet_current_frame() "error" path, which is unnecessary in this case since it's enough to just quit the function. Also, in case MSG_DONTWAIT is not set, we should rather test for need_resched() first and do schedule() only if necessary since meanwhile pending frames could already have finished processing and called skb destructor.

Most people acquire PF_PACKET sockets with a protocol argument in the socket call, e.g. libpcap does so with htons(ETH_P_ALL) for all its sockets. Most likely, at some point in time a subsequent bind() call will follow, e.g. in libpcap with ... memset(&sll, 0, sizeof(sll)); sll.sll_family = AF_PACKET; sll.sll_ifindex = ifindex; sll.sll_protocol = htons(ETH_P_ALL); ... as arguments. What happens in the kernel is that already in socket() syscall, we install a proto hook via register_prot_hook() if our protocol argument is != 0. Yet, in bind() we're almost doing the same work by doing a unregister_prot_hook() with an expensive synchronize_net() call in case during socket() the proto was != 0, plus follow-up register_prot_hook() with a bound device to it this time, in order to limit traffic we get. In the case when the protocol and user supplied device index (== 0) does not change from socket() to bind(), we can spare us doing the same work twice. Similarly for re-binding to the same device and protocol. For these scenarios, we can decrease create/bind latency from ~7447us (sock-bind-2 case) to ~89us (sock-bind-1 case) with this patch. Alternatively, for the first case, if people care, they should simply create their sockets with proto == 0 argument and define the protocol during bind() as this saves a call to synchronize_net() as well (sock-bind-3 case). In all other cases, we're tied to user space behaviour we must not change, also since a bind() is not strictly required. Thus, we need the synchronize_net() to make sure no asynchronous packet processing paths still refer to the previous elements of po->prot_hook. In case of mmap()ed sockets, the workflow that includes bind() is socket() -> setsockopt(<ring>) -> bind(). In that case, a pair of {__unregister, register}_prot_hook is being called from setsockopt() in order to install the new protocol receive handler. Thus, when we call bind and can skip a re-hook, we have already previously installed the new handler. For fanout, this is handled different entirely, so we should be good. Timings on an i7-3520M machine: * sock-bind-1: 89 us * sock-bind-2: 7447 us * sock-bind-3: 75 us sock-bind-1: socket(PF_PACKET, SOCK_RAW, htons(ETH_P_IP)) = 3 bind(3, {sa_family=AF_PACKET, proto=htons(ETH_P_IP), if=all(0), pkttype=PACKET_HOST, addr(0)={0, }, 20) = 0 sock-bind-2: socket(PF_PACKET, SOCK_RAW, htons(ETH_P_IP)) = 3 bind(3, {sa_family=AF_PACKET, proto=htons(ETH_P_IP), if=lo(1), pkttype=PACKET_HOST, addr(0)={0, }, 20) = 0 sock-bind-3: socket(PF_PACKET, SOCK_RAW, 0) = 3 bind(3, {sa_family=AF_PACKET, proto=htons(ETH_P_IP), if=lo(1), pkttype=PACKET_HOST, addr(0)={0, }, 20) = 0 Signed-off-by: -

Recent commit 438e38fa ("gre_offload: statically build GRE offloading support") added new module_init/module_exit calls to the gre_offload.c file. The file is obj-y and can't be anything other than built-in. Currently it can never be built modular, so using module_init as an alias for __initcall can be somewhat misleading. Fix this up now, so that we can relocate module_init from init.h into module.h in the future. If we don't do this, we'd have to add module.h to obviously non-modular code, and that would be a worse thing. We also make the inclusion explicit. Note that direct use of __initcall is discouraged, vs. one of the priority categorized subgroups. As __initcall gets mapped onto device_initcall, our use of device_initcall directly in this change means that the runtime impact is zero -- it will remain at level 6 in initcall ordering. As for the module_exit, rather than replace it with __exitcall, we simply remove it, since it appears only UML does anything with those, and even for UML, there is no relevant cleanup to be done here.

Srinivas Kandagatla says: ==================== net: stmmac PM related fixes. During PM_SUSPEND_FREEZE testing, I have noticed that PM support in STMMAC is partly broken. I had to re-arrange the code to do PM correctly. There were lot of things I did not like personally and some bits did not work in the first place. I thought this is the nice opportunity to clean the mess up. Here is what I did: any 1> Test PM suspend freeze via pm_test It did not work for following reasons. - If the power to gmac is removed when it enters in low power state. stmmac_resume could not cope up with such behaviour, it was expecting the ip register contents to be still same as before entering low power, This assumption is wrong. So I started to add some code to do Hardware initialization, thats when I started to re-arrange the code. stmmac_open contains both resource and memory allocations and hardware initialization. I had to separate these two things in two different functions. These two patches do that net: stmmac: move dma allocation to new function net: stmmac: move hardware setup for stmmac_open to new function And rest of the other patches are fixing the loose ends, things like mdio reset, which might be necessary in cases likes hibernation(I did not test). In hibernation cases the driver was just unregistering with subsystems and releasing resources which I did not like and its not necessary to do this as part of PM. So using the same stmmac_suspend/resume made more sense for hibernation cases than using stmmac_open/release. Also fixed a NULL pointer dereference bug too. 2> Test WOL via PM_SUSPEND_FREEZE Did get an wakeup interrupt, but could not wakeup a freeze system. So I had to add pm_wakeup_event to the driver. net: stmmac: notify the PM core of a wakeup event. patch. Also few patches like net: stmmac: make stmmac_mdio_reset non-static net: stmmac: restore pinstate in pm resume. helps the resume function to reset the phy and put back the pins in default state. Changes since RFC: - Rebased to net-next on Dave's suggestion. All these patches are Acked by Peppe. ==================== Signed-off-by: -

In PM_SUSPEND_FREEZE and WOL(Wakeup On Lan) case, when the driver gets a wakeup event, either the driver or platform specific PM code should notify the pm core about it, so that the system can wakeup from low power. In cases where there is no involvement of platform specific PM, it becomes driver responsibility to notify the PM core to wakeup the system. Without this WOL with PM_SUSPEND_FREEZE does not work on STi based SOCs. Signed-off-by:

In hibernation freeze case the driver just releases the resources like dma buffers, irqs, unregisters the drivers and during restore it does register, request the resources. This is not really necessary, as part of power management all the data structures are intact, all the previously allocated resources can be used after coming out of low power. This patch uses the suspend and resume callbacks for freeze and restore which initializes the hardware correctly without unregistering or releasing the resources, this should also help in reducing the time to restore. Also this patch fixes a bug in stmmac_pltfr_restore and stmmac_pltfr_freeze where it tries to get hold of platform data via dev_get_platdata call, which would return NULL in device tree cases and the next if statement would crash as there is no NULL check.

The driver PM resume assumes that the IP is still powered up and the all the register contents are not disturbed when it comes out of low power suspend case. This assumption is wrong, basically the driver should not consider any state of registers after it comes out of low power. However driver can keep the part of the IP powered up if its a wake up source. But it can not assume the register state of the IP. Also its possible that SOC glue layer can take the power off the IP if its not wake-up source to reduce the power consumption. This patch re initializes hardware by calling stmmac_hw_setup function in resume case. Signed-off-by:
