selftests: net: relocate gro and toeplitz tests to drivers/net

2025-11-21T02:19:29Z

The GRO test can run on a real device or a veth. The Toeplitz hash test can only run on a real device. Move them from net/ to drivers/net/ and drivers/net/hw/ respectively. There are two scripts which set up the environment for these tests setup_loopback.sh and setup_veth.sh. Move those scripts to net/lib. The paths to the setup files are a little ugly but they will be deleted shortly. toeplitz_client.sh is not a test in itself, but rather a helper to send traffic, so add it to TEST_FILES rather than TEST_PROGS.

selftests/net: use unique netns name for setup_loopback.sh setup_veth.sh

2023-12-23T00:26:32Z

The setup_loopback and setup_veth use their own way to create namespace. So let's just re-define server_ns/client_ns to unique name. At the same time update the namespace name in gro.sh and toeplitz.sh. As I don't have env to run toeplitz.sh. Here is only the gro test result. # ./gro.sh running test ipv4 data Expected {200 }, Total 1 packets Received {200 }, Total 1 packets. ... Gro::large test passed. All Tests Succeeded!

selftests: net: Use "grep -E" instead of "egrep"

2022-12-03T04:56:41Z

The latest version of grep claims the egrep is now obsolete so the build now contains warnings that look like: egrep: warning: egrep is obsolescent; using grep -E fix this using "grep -E" instead. sed -i "s/egrep/grep -E/g" `grep egrep -rwl tools/testing/selftests/net` Here are the steps to install the latest grep: wget http://ftp.gnu.org/gnu/grep/grep-3.8.tar.gz tar xf grep-3.8.tar.gz cd grep-3.8 && ./configure && make sudo make install export PATH=/usr/local/bin:$PATH Signed-off-by: Tiezhu Yang Link: https://lore.kernel.org/r/1669864248-829-1-git-send-email-yangtiezhu@loongson.cn Signed-off-by: Jakub Kicinski

selftests/net: toeplitz test

2021-08-05T12:14:09Z

To verify that this hash implements the Toeplitz hash function. Additionally, provide a script toeplitz.sh to run the test in loopback mode on a networking device of choice (see setup_loopback.sh). Since the script modifies the NIC setup, it will not be run by selftests automatically. Tested: ./toeplitz.sh -i eth0 -irq_prefix -t -6 carrier ready rxq 0: cpu 14 rxq 1: cpu 20 rxq 2: cpu 17 rxq 3: cpu 23 cpu 14: rx_hash 0x69103ebc [saddr fda8::2 daddr fda8::1 sport 58938 dport 8000] OK rxq 0 (cpu 14) ... cpu 20: rx_hash 0x257118b9 [saddr fda8::2 daddr fda8::1 sport 59258 dport 8000] OK rxq 1 (cpu 20) count: pass=111 nohash=0 fail=0 Test Succeeded!
