Since i354 2.5Gb devices are not Copper media type but SerDes, so this patch changes the way we detect speed/duplex link info for this device. Signed-off-by:

PHY Power Management does not exist for i354 device. So, there is no need to read and write this register or clear go link Disconnect bit, which could cause a lot of issues. Signed-off-by:

This patch implements downshift mechanism for M88E1543 PHY, so that downshift is disabled first during link setup process, and later enabled if we are master and downshift link is negotiated. Also cleaned up return code implementation. Signed-off-by:

tcp_rcv_established() returns only one value namely 0. We change the return value to void (as suggested by David Miller). After commit 0c24604b (tcp: implement RFC 5961 4.2), we no longer send RSTs in response to SYNs. We can remove the check and processing on the return value of tcp_rcv_established(). We also fix jtcp_rcv_established() in tcp_probe.c to match that of tcp_rcv_established(). Signed-off-by:

With recent changes in tcp_probe module (e.g. f925d0a6 ("net: tcp_probe: add IPv6 support")) we also need to take into account that tbuf needs to be updated as format string will be further expanded. tbuf sits on the stack in tcpprobe_read() function that is invoked when user space reads procfs file /proc/net/tcpprobe, hence not fast path as in jtcp_rcv_established(). Having a size similarly as in sctp_probe module of 256 bytes is fully sufficient for that, we need theoretical maximum of 252 bytes otherwise we could get truncated. Signed-off-by:

This was found with a manual audit and I don't have a reproducer. We limit ->calling_len and ->called_len when we get them from copy_from_user() in x25_ioctl() so when they come from skb->data then we should cap them there as well. Signed-off-by:

"tty->name" and "name" are a 64 character buffers. My static checker complains because we add the "cf" on the front so it look like we are copying a 66 character string into a 64 character buffer. Also if the name is larger than IFNAMSIZ (16) it triggers a BUG_ON() inside the call to alloc_netdev(). This is all under CAP_SYS_ADMIN so it's not a security fix, it just adds a little robustness.

Currently we're linking upper devices to lower ones, which results in upside-down relationship: upper devices seeing lower devices via its upper lists.

This function was only used when a packet was sent to another netns. Now, it can also be used after tunnel encapsulation or decapsulation. Only skb_orphan() should not be done when a packet is not crossing netns. Signed-off-by:

We can drop the use of bond->lock for mutual exclusion in bond_3ad_update_lacp_rate and use RTNL in the sysfs store function instead. This way we'll prevent races with mode change and interface up/down as well as simplify update_lacp_rate by removing the check for port->slave because it'll always be initialized (done while enslaving with RTNL). This change will also help in the future removal of reader bond->lock from bond_enslave. Signed-off-by:

This patch aims to remove a use of the bond->lock for mutual exclusion which will later allow easier migration to RCU of the users of this functionality. We use RTNL as a synchronizing mechanism since it's always held when send_peer_notif is set, and when it is decremented from the notifier function. We can also drop some locking, and fix the leakage of the send_peer_notif counter. Signed-off-by:

As Michael point out, We used to limit the max pending DMAs to get better cache utilization. But it was not done correctly since it was one done when there's no new buffers submitted from guest. Guest can easily exceeds the limitation by keeping sending packets. So this patch moves the check into main loop. Tests shows about 5%-10% improvement on per cpu throughput for guest tx.

We used to poll vhost queue before making DMA is done, this is racy if vhost thread were waked up before marking DMA is done which can result the signal to be missed. Fix this by always polling the vhost thread before DMA is done. Signed-off-by:

Currently, even if the packet length is smaller than VHOST_GOODCOPY_LEN, if upend_idx != done_idx we still set zcopy_used to true and rollback this choice later. This could be avoided by determining zerocopy once by checking all conditions at one time before. Signed-off-by:

We tend to batch the used adding and signaling in vhost_zerocopy_callback() which may result more than 100 used buffers to be updated in vhost_zerocopy_signal_used() in some cases. So switch to use vhost_add_used_and_signal_n() to avoid multiple calls to vhost_add_used_and_signal(). Which means much less times of used index updating and memory barriers. 2% performance improvement were seen on netperf TCP_RR test. Signed-off-by:
