Hi All

The switch crashed after it received following flow mod.
[version=0x04,flow mod(DELETE,match:inport=1,no instructions),
length=0x40,xid=0xf]
0x0000: 040e0040 0000000f 00000000 00000000
0x0010: 00000000 00000000 ff030000 00000000
0x0020: 00000000 ffffffff 00000000 00000000
0x0030: 0001000c 80000004 00000001 00000000

Could you check?

By the way,in the case of DELETE,match:inport=any and no instructions,
no problems occur.

A mistake was found.
By the way,in the case of DELETE,match:inport=any and no instructions,(mistake)
By the way,in the case of DELETE,match:all any and no instructions, (correct)
no problems occur.

I couldn't reproduce the error. Here's is the switch log when it receives
the flow

Feb 21 08:51:31|01907|dp_ctrl|DBG|received control msg:
flow_mod{table="all", cmd="del", cookie="0x0", mask="0x0", idle="0",
hard="0", prio="32768", buf="none", port="any", group="any", flags="0x0",
match=oxm{in_port="1"}, insts=[]}

I'm sending the rule via dpctl. Are you using a controller? Could you give
us more background on that error?
Thank you.

I found the problem, it was due to non strict matching all oxm flows.
Thanks.
