Subject: [PATCH] extensions: hashlimit: Fix tests with HZ=100
|
|
|
6ab069 |
|
|
|
6ab069 |
With the kernel ticking at 100Hz, a limit of 1/day with burst 5 does not
|
|
|
6ab069 |
overflow in kernel, making the test unstable depending on kernel config.
|
|
|
6ab069 |
Change it to not overflow with 1000Hz either by increasing the burst
|
|
|
6ab069 |
value by a factor of 100.
|
|
|
6ab069 |
|
|
|

Fixes: fcf9f6f25db11 ("extensions: libxt_hashlimit: add unit test")
