* src: 'nft list chain' prints anonymous chains correctlyPablo Neira Ayuso2022-01-151-0/+19
| | | | | | | | | If the user is requesting a chain listing, e.g. nft list chain x y and a rule refers to an anonymous chain that cannot be found in the cache, then fetch such anonymous chain and its ruleset. Closes: https://bugzilla.netfilter.org/show_bug.cgi?id=1577 Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* tests: shell: don't assume fixed handle value in cache/0008_delete_by_handle_0Pablo Neira Ayuso2021-05-121-5/+10
| | | | | | | | This test is occasionally reporting warning in one of my test boxes. Update this test to extract the handle from ruleset listing, use rudimentary invocation of the cut command to work around this. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* rule: skip fuzzy lookup for unexisting 64-bit handlePablo Neira Ayuso2021-05-021-0/+8
| | | | | | | | Deletion by handle, if incorrect, should not exercise the misspell lookup functions. Fixes: 3a0e07106f66 ("src: combine extended netlink error reporting with mispelling support") Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* src: unbreak deletion by table handlePablo Neira Ayuso2021-05-021-0/+20
| | | | | | | | | Use NFTA_TABLE_HANDLE instead of NFTA_TABLE_NAME to refer to the table 64-bit unique handle.

* main: enforce options before commandsPablo Neira Ayuso2019-12-181-1/+1
| | | | | | | | | | | | | | | | | This patch turns on POSIXLY_CORRECT on the getopt parser to enforce options before commands. Users get a hint in such a case: # nft list ruleset -a Error: syntax error, options must be specified before commands nft list ruleset -a ^ ~~ This patch recovers 9fc71bc6b602 ("main: Fix for misleading error with negative chain priority"). Tests have been updated. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

* cache: incorrect flush flag for table/chainLaura Garcia Liebana2019-07-312-0/+32
| | | | | | | | | | | | | | | | | | | After the new cache system, nft raises a table error flushing a chain in a transaction. # nft "flush chain ip nftlb filter-newfarm ; \ add rule ip nftlb filter-newfarm update \ @persist-newfarm { ip saddr : ct mark } ; \ flush chain ip nftlb nat-newfarm" Error: No such file or directory flush chain ip nftlb filter-newfarm ; add rule ip nftlb (...) ^^^^^ This patch sets the cache flag properly to save this case.

| | | | | | | | | | | | | | | | | | | | Make sure nft behaves like 0.9.0 -- the ruleset flush ruleset table inet filter { } table inet filter { chain test { counter } } loads again without crashing/generating an error message.

* src: Support intra-transaction rule referencesPhil Sutter2019-06-071-0/+7
| | | | | | | | | | | | | | | | | | | | | | | A rule may be added before or after another one using index keyword. To support for the other rule being added within the same batch, one has to make use of NFTNL_RULE_ID and NFTNL_RULE_POSITION_ID attributes. This patch does just that among a few more crucial things: * If cache is complete enough to contain rules, update cache when evaluating rule commands so later index references resolve correctly. * Reduce rule_translate_index() to its core code which is the actual linking of rules and consequently rename the function. The removed bits are pulled into the calling rule_evaluate() to reduce code duplication in between cache updates with and without rule reference. * Pass the current command op to rule_evaluate() as indicator whether to insert before or after a referenced rule or at beginning or end of chain in cache. Exploit this from chain_evaluate() to avoid adding the chain's rules a second time. Signed-off-by: Phil Sutter <phil@nwl.cc> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

* src: update cache if cmd is more specificEric Garver2019-05-241-0/+14
| | | | | | | | | | | | | | | | | If we've done a partial fetch of the cache and the genid is the same the cache update will be skipped without fetching the needed items. This change flushes the cache if the new request is more specific than the current cache - forcing a cache update which includes the needed items. Introduces a simple scoring system which reflects how cache_init_objects() looks at the current command to decide if it is finished already or not. Then use that in cache_needs_more(): If current command's score is higher than old command's, cache needs an update.

* tests/shell: Add testcase for cache update problemsPhil Sutter2018-10-291-0/+29
| | | | | | | | | The first test in there shows how the current cache update strategy causes trouble. The second test shows that proposed "locking" of cache when local entries are added is flawed, too. Signed-off-by: Phil Sutter <phil@nwl.cc> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* tests: shell: add quotes when using <<<-style here documentFlorian Westphal2018-06-082-4/+4
| | | | | | | | | bash 4.3.30 removes newlines in RULESET when "" are omitted, which then causes nft -f to complain about invalid syntax. As a result, all test cases that use this here-doc style fail. Signed-off-by: Florian Westphal <fw@strlen.de>
* tests: shell: add crash reproducerFlorian Westphal2018-06-071-0/+4
| | | | | | | | | | | | | | | | | | | Two reports point to a crash in nft when 'flush' is provided on existing ruleset. In that case, nft will crash with a null-ptr dereference. "evaluate: do not inconditionally update cache from flush command" causes the commit to fail due to a cache inconsistency, we then trip over NULL location->indesc. Cause of 2nd bug not known yet, not sure how to fix cache issue either, so only adding reproducer so this can be fixed later.

* Support 'nft -f -' to read from stdinPhil Sutter2018-03-202-23/+6
| | | | | | | | | | | | | | | | | | In libnftables, detect if given filename is '-' and treat it as the common way of requesting to read from stdin, then open /dev/stdin instead. (Calling 'nft -f /dev/stdin' worked before as well, but this makes it official.) With this in place and bash's support for here strings, review all tests in tests/shell for needless use of temp files. Note that two categories of test cases were intentionally left unchanged: - Tests creating potentially large rulesets to avoid running into shell parameter length limits. - Tests for 'include' directive for obvious reasons.

* tests: shell: autogenerate dump verificationLaura Garcia Liebana2018-03-092-0/+19
| | | | | | | | | | | | | | | | | | | | Complete the automated shell tests with the verification of the test file dump, only for positive tests and if the test execution was successful. It's able to generate the dump file with the -g option. Example: # ./run-tests.sh -g testcases/chains/0001jumps_0 The dump files are generated in the same path in the folder named dumps/ with .nft extension. It has been avoided the dump verification code in every test file. Signed-off-by: Laura Garcia Liebana <nevola@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
