Subject: [PATCH] ebtables: Fix rule listing with counters
|
|
|
8cce6c |
|
|
|
8cce6c |
This is a partial revert of commit 583b27eabcad6 ("ebtables-save: add -c
|
|
|
8cce6c |
option, using xtables-style counters") which broke ruleset listing with
|
|
|
8cce6c |
'--Lc' flag turned on:
|
|
|
8cce6c |
|
|
|
8cce6c |
| # ebtables-nft -L --Lc
|
|
|

| Bridge table: filter
|
|
|

|
|
|
|
8cce6c |
| Bridge chain: INPUT, entries: 0, policy: ACCEPT
|
|
|

|
|
|
|

| Bridge chain: FORWARD, entries: 2, policy: ACCEPT

| -j foo
|
|
|
8cce6c |
| , pcnt = 0 -- bcnt = 0-j ACCEPT
|
|
|
8cce6c |
| , pcnt = 0 -- bcnt = 0
|
|
|
8cce6c |
| Bridge chain: OUTPUT, entries: 0, policy: ACCEPT
|
|
|
8cce6c |
|
|
|
|
8cce6c |
| Bridge chain: foo, entries: 1, policy: RETURN
|
|
|
8cce6c |
| -j ACCEPT
|
|
|
8cce6c |
| , pcnt = 0 -- bcnt = 0%
|
|
|
8cce6c |
|
|
|
8cce6c |
(That percentage sign means no newline after last line of output and
|
|
|
8cce6c |
doesn't belong to ebtables-nft's output.)
|
|
|
8cce6c |
|
|
|
8cce6c |
Problem was that nft_bridge_print_rule() printed the counters after
|
|
|
8cce6c |
nft_bridge_save_rule() had already printed the newline character.
|
|
|
8cce6c |
|
|
|
8cce6c |
Note also that there is no need to remove FMT_EBT_SAVE bit from 'format'
|
|
|
8cce6c |
variable: It is set only by ebtables-nft-save which doesn't call
|
|
|
8cce6c |
nft_bridge_print_rule().
