Subject: [PATCH] ebtables: Dump atomic waste
|
||||
|
||||
With ebtables-nft.8 now educating people about the missing
|
||||
functionality, get rid of atomic remains in source code. This eliminates
|
||||
mostly comments except for --atomic-commit which was treated as alias of
|
||||
--init-table. People not using the latter are probably trying to
|
||||
atomic-commit from an atomic-file which in turn is not supported, so no
|
||||
point keeping it.

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

Subject: [PATCH] extensions: hashlimit: Fix tests with HZ=1000
|
||||
|
||||
In an attempt to fix for failing hashlimit tests with HZ=100, the
|
||||
expected failures were changed so they are expected to pass and the
|
||||
parameters changed to seemingly fix them. Yet while the new parameters
|
||||
worked on HZ=100 systems, with higher tick rates they didn't so the
|
||||
observed problem moved from the test failing on HZ=100 to failing on
|
||||
HZ=1000 instead.
|
||||
|
||||
Kernel's error message "try lower: 864000000/5" turned out to be a red
|
||||
herring: The burst value does not act as a dividor but a multiplier
|
||||
instead, so in order to lower the overflow-checked value, a lower burst
|
||||
value must be chosen. Inded, using a burst value of 1 makes the kernel
|
||||
accept the rule in both HZ=100 and HZ=1000 configurations.
