There were quite a few overlapping sets of changes here. Daniel's bug fix for off-by-ones in the new BPF branch instructions, along with the added allowances for "data_end > ptr + x" forms collided with the metadata additions. Along with those three changes came veritifer test cases, which in their final form I tried to group together properly. If I had just trimmed GIT's conflict tags as-is, this would have split up the meta tests unnecessarily. In the socketmap code, a set of preemption disabling changes overlapped with the rename of bpf_compute_data_end() to bpf_compute_data_pointers(). Changes were made to the mv88e6060.c driver set addr method which got removed in net-next. The hyperv transport socket layer had a locking change in 'net' which overlapped with a change of socket state macro usage in 'net-next'. Signed-off-by: David S. Miller

net/xen-netback: Convert timers to use timer_setup()

2017-10-18T11:40:27Z

In preparation for unconditionally passing the struct timer_list pointer to all timer callbacks, switch to using the new timer_setup() and from_timer() to pass the timer pointer explicitly.

xen-netfront, xen-netback: Use correct minimum MTU values

2017-10-16T20:00:44Z

RFC791 specifies the minimum MTU to be 68, while xen-net{front|back} drivers use a minimum value of 0. When set MTU to 0~67 with xen_net{front|back} driver, the network will become unreachable immediately, the guest can no longer be pinged. xen_net{front|back} should not allow the user to set this value which causes network problems.

xen-netback: update ubuf_info initialization to anonymous union

2017-08-28T22:11:50Z

The xen driver initializes struct ubuf_info fields using designated initializers. I recently moved these fields inside a nested anonymous struct inside an anonymous union. I had missed this use case. This breaks compilation of xen-netback with older compilers. >From kbuild bot with gcc-4.4.7: drivers/net//xen-netback/interface.c: In function 'xenvif_init_queue': >> drivers/net//xen-netback/interface.c:554: error: unknown field 'ctx' specified in initializer >> drivers/net//xen-netback/interface.c:554: warning: missing braces around initializer drivers/net//xen-netback/interface.c:554: warning: (near initialization for '(anonymous).') >> drivers/net//xen-netback/interface.c:554: warning: initialization makes integer from pointer without a cast >> drivers/net//xen-netback/interface.c:555: error: unknown field 'desc' specified in initializer Add double braces around the designated initializers to match their nested position in the struct. After this, compilation succeeds again.

xen-netback: correctly schedule rate-limited queues

2017-06-22T15:15:42Z

Add a flag to indicate if a queue is rate-limited. Test the flag in NAPI poll handler and avoid rescheduling the queue if true, otherwise we risk locking up the host. The rescheduling will be done in the timer callback function. Reported-by: Jean-Louis Dupond Signed-off-by: Wei Liu Tested-by: Jean-Louis Dupond Reviewed-by: Paul Durrant Signed-off-by: David S.
