In this unit test,we will test the filter redirector function.
Case 1, tx traffic flow:
qemu side | test side
|
+---------+ | +-------+
| backend <---------------+ sock0 |
+----+----+ | +-------+
| |
+----v----+ +-------+ |
| rd0 +->+chardev| |
+---------+ +---+---+ |
| |
+---------+ | |
| rd1 <------+ |
+----+----+ |
| |
+----v----+ | +-------+
| rd2 +--------------->sock1 |
+---------+ | +-------+
+
a. we(sock0) inject packet to qemu socket backend
b. backend pass packet to filter redirector0(rd0)
c. rd0 redirect packet to out_dev(chardev) which is connected with
filter redirector1's(rd1) in_dev
d. rd1 read this packet from in_dev, and pass to next filter redirector2(rd2)
e. rd2 redirect packet to rd2's out_dev which is connected with an opened socketed(sock1)
f. we read packet from sock1 and compare to what we inject
Start qemu with:
"-netdev socket,id=qtest-bn0,fd=%d "
"-device rtl8139,netdev=qtest-bn0,id=qtest-e0 "
"-chardev socket,id=redirector0,path=%s,server,nowait "
"-chardev socket,id=redirector1,path=%s,server,nowait "
"-chardev socket,id=redirector2,path=%s,nowait "
"-object filter-redirector,id=qtest-f0,netdev=qtest-bn0,"
"queue=tx,outdev=redirector0 "
"-object filter-redirector,id=qtest-f1,netdev=qtest-bn0,"
"queue=tx,indev=redirector2 "
"-object filter-redirector,id=qtest-f2,netdev=qtest-bn0,"
"queue=tx,outdev=redirector1 "
--------------------------------------
Case 2, rx traffic flow
qemu side | test side
|
+---------+ | +-------+
| backend +---------------> sock1 |
+----^----+ | +-------+
| |
+----+----+ +-------+ |
| rd0 +<-+chardev| |
+---------+ +---+---+ |
^ |
+---------+ | |
| rd1 +------+ |
+----^----+ |
| |
+----+----+ | +-------+
| rd2 <---------------+sock0 |
+---------+ | +-------+
a. we(sock0) insert packet to filter redirector2(rd2)
b. rd2 pass packet to filter redirector1(rd1)
c. rd1 redirect packet to out_dev(chardev) which is connected with
filter redirector0's(rd0) in_dev
d. rd0 read this packet from in_dev, and pass ti to qemu backend which is
connected with an opened socketed(sock1)
e. we read packet from sock1 and compare to what we inject
Start qemu with:
"-netdev socket,id=qtest-bn0,fd=%d "
"-device rtl8139,netdev=qtest-bn0,id=qtest-e0 "
"-chardev socket,id=redirector0,path=%s,server,nowait "
"-chardev socket,id=redirector1,path=%s,server,nowait "
"-chardev socket,id=redirector2,path=%s,nowait "
"-object filter-redirector,id=qtest-f0,netdev=qtest-bn0,"
"queue=rx,outdev=redirector0 "
"-object filter-redirector,id=qtest-f1,netdev=qtest-bn0,"
"queue=rx,indev=redirector2 "
"-object filter-redirector,id=qtest-f2,netdev=qtest-bn0,"
"queue=rx,outdev=redirector1 "
