Marcelo Ricardo Leitner says: ==================== sctp: delay calls to sk_data_ready() as much as possible 1st patch is a preparation for the 2nd. The idea is to not call ->sk_data_ready() for every data chunk processed while processing packets but only once before releasing the socket. v2: patchset re-checked, small changelog fixes v3: on patch 2, make use of local vars to make it more readable ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

由 Marcelo Ricardo Leitner 提交于
Currently processing of multiple chunks in a single SCTP packet leads to multiple calls to sk_data_ready, causing multiple wake up signals which are costy and doesn't make it wake up any faster. With this patch it will note that the wake up is pending and will do it before leaving the state machine interpreter, latest place possible to do it realiably and cleanly. Note that sk_data_ready events are not dependent on asocs, unlike waking up writers. v2: series re-checked v3: use local vars to cleanup the code, suggested by Jakub Sitnicki Signed-off-by: NMarcelo Ricardo Leitner <marcelo.leitner@gmail.com> Signed-off-by: NDavid S.

It wastes space and gets worse as we add new flags, so convert bit-wide flags to a bitfield. Currently it already saves 4 bytes in sctp_sock, which are left as holes in it for now. The whole struct needs packing, which should be done in another patch. Note that do_auto_asconf cannot be merged, as explained in the comment before it.

Now when we change the attributes of bridge or br_port by netlink, a relevant netlink notification will be sent, but if we change them by ioctl or sysfs, no notification will be sent. We should ensure that whenever those attributes change internally or from sysfs/ioctl, that a netlink notification is sent out to listeners.

The original tokenized iid support implemented via f53adae4 ("net: ipv6: add tokenized interface identifier support") didn't allow for clearing a device token as it was intended that this addressing mode was the only one active for globally scoped IPv6 addresses. Later we relaxed that restriction via 617fe29d ("net: ipv6: only invalidate previously tokenized addresses"), and we should also allow for clearing tokens as there's no good reason why it shouldn't be allowed.

Andrew Lunn says: ==================== DSA refactoring: set 1 There has been a long running effort to refractor DSA probing to make the switches true linux devices. Here are a small collection of patches moving in this direction. Most have been seen before. We take a little step forward by passing the dsa device point to the driver, thus allowing it to perform resource allocations using the normal mechanisms. This device structure will later be replaced by the devices own device structure. Future patches will add a true driver probe function, so we rename the current probe function, cleaning up the namespace. phys_port_mask continually confuses me, thinking it is about PHYs. But it is actually about ports enabled to the outside world. So rename it to enabled_port_mask. Lots more patches yet to follow, this is just doing some ground work. v2: enabled_port_mask instread of user_port_masks Added Tested-by's and Reviewed-by. ==================== Tested-by: NFlorian Fainelli <f.fainelli@gmail.com> Signed-off-by: NDavid S.

John Crispin says: ==================== net: mediatek: make the driver pass stress tests While testing the driver we managed to get the TX path to stall and fail to recover. When dual MAC support was added to the driver, the whole queue stop/wake code was not properly adapted. There was also a regression in the locking of the xmit function. The fact that watchdog_timeo was not set and that the tx_timeout code failed to properly reset the dma, irq and queue just made the mess complete. This series make the driver pass stress testing. With this series applied the testbed has been running for several days and still has not locked up. We have a second setup that has a small hack patch applied to randomly stop irqs and/or one of the queues and successfully manages to recover from these simulated tx stalls. ==================== Signed-off-by: NDavid S.

The QID field gets set to the mac id. This made the DMA linked list queue the traffic of each MAC on a different internal queue. However during long term testing we found that this will cause traffic stalls as the multi queue setup requires a more complete initialisation which is not part of the upstream driver yet. This patch removes the code setting the QID field, resulting in all traffic ending up in queue 0 which works without any special setup.
