Subject: [PATCH] nft: Fix error reporting for refreshed transactions
|
||
|
|
|
||
|
|
When preparing a batch from the list of batch objects in nft_action(),
|
||
|
|
the sequence number used for each object is stored within that object
|
||
|
|
for later matching against returned error messages. Though if the
|
||
|
|
transaction has to be refreshed, some of those objects may be skipped,
|
||
|
|
other objects take over their sequence number and errors are matched to
|
||
|
|
skipped objects. Avoid this by resetting the skipped object's sequence
|
||
|
|
number to zero.
|
||
|
|
|
||
|
|
Fixes: 58d7de0181f61 ("xtables: handle concurrent ruleset modifications")
