* flowtable: Make parsing a little more robustPhil Sutter2018-03-201-0/+14
| | | | | | | | | | It was surprisingly easy to crash nft with invalid syntax in 'add flowtable' command. Catch at least three possible ways (illustrated in provided test case) by making evaluation phase survive so that bison gets a chance to complain.

* tests/shell: Fix flowtable test casesPhil Sutter2018-03-207-14/+14
| | | | | | | | | | | | | The major problem here was that existence of network interfaces 'eth0' and 'wlan0' was assumed. Overcome this by just using 'lo' instead, which exists even in newly created netns by default. Another minor issue was false naming of 0004delete_after_add0 - the expected return code is supposed to be separated by '_' from the remaining filename.

* Support 'nft -f -' to read from stdinPhil Sutter2018-03-201-11/+1
| | | | | | | | | | | | | | | | | | 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 Liebana2018-03-092-8/+10
| | | | | | | | | | | | | | | | | | | | 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>
