Upstream Status: nftables commit 8d51f169e0e83
|
|
|
8acaf9 |
Conflicts:
|
|
|
8acaf9 |
* Adjusted changes to missing commit a84f9329d2f6c
|
|
|
8acaf9 |
("src: use location to display error messages").
|
|
|
8acaf9 |
* Error message changed to not suggest 'nft -j' which doesn't exist in
|
|
|
8acaf9 |
RHEL7.
|
|
|
8acaf9 |
* Man page changes applied manually, upstream converted to asciidoc in
|
|
|
8acaf9 |
between.
|
|
|
8acaf9 |
* Include netlink.h from src/evaluate.c to make NFTNL_OUTPUT_JSON
|
|
|
8acaf9 |
known. Upstream added this in unrelated commit 1524134b0bc01
|
|
|
8acaf9 |
("src: osf: load pf.os from expr_evaluate_osf()").

src: Reject 'export vm json' command
|
|
|
8acaf9 |
|
|
|
8acaf9 |
Since libnftnl recently dropped JSON output support, this form of JSON
|
|
|
8acaf9 |
export is not available anymore. Point at 'nft -j list ruleset' command
|
|
|
8acaf9 |
for a replacement in error message.
|
|
|
8acaf9 |
|
|
|
8acaf9 |
Since 'export' command is not useable anymore, remove it from
|
|
|
8acaf9 |
documentation. Instead point out that 'list ruleset' command serves well
|
|
|
8acaf9 |
for dumping and later restoring.
|
|
|
8acaf9 |
|
|
|
8acaf9 |
To not cause pointless inconvenience for users wishing to store their
|
|
|
8acaf9 |
ruleset in JSON format, make JSON parser fallback to CMD_ADD if no
|
|
|
8acaf9 |
recognized command property was found. This allows to feed the output of
|
|
|
8acaf9 |
'nft -j list ruleset' into 'nft -f' without any modification.
