* cli: add libedit supportPablo Neira Ayuso2021-01-051-1/+1
| | | | | | | | Extend cli to support for libedit readline shim code: ./configure --with-cli=editline Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* cli: add linenoise CLI implementation.Jeremy Sowden2019-10-151-1/+1
| | | | | | | | By default, continue to use libreadline, but if `--with-cli=linenoise` is passed to configure, build the linenoise implementation instead. Signed-off-by: Jeremy Sowden <jeremy@azazel.net> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

| | | | | | | | cli.h includes a forward declaration of struct parser_state which is not needed. Remove it. Signed-off-by: Jeremy Sowden <jeremy@azazel.net> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

* cli: Use nft_run_cmd_from_buffer()Phil Sutter2017-10-241-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make CLI code adhere to intended libnftables API by not open coding what nft_run_cmd_from_buffer() does. This way, nft_run() has no users outside of src/libnftables.c anymore and therefore can become static. Since nft_run_cmd_from_buffer() takes care of scanner initialization and libmnl socket passed to cli_init() is present as nft_ctx field as well, signature of cli_init() can be reduced to just take nft_ctx pointer as single argument. Note that this change introduces two (possibly unwanted) side-effects: * Input descriptor passed to scanner_push_buffer() is changed from the CLI-specific one to the one used by nft_run_cmd_from_buffer(). In practice though, this doesn't make a difference: input descriptor types INDESC_CLI and INDESC_BUFFER are treated equally by erec_print(). Also, scanner_push_buffer() NULLs input descriptor name, so that is not used at all in latter code. * Error messages are printed to stderr instead of cli_nft->output. This could be fixed by introducing an 'error_output' field in nft_ctx for nft_run_cmd_from_buffer() to use when printing error messages.

| | | | | | | | Remove cli_display() function, as it is not called anywhere in source code. Signed-off-by: Varsha Rao <rvarsha016@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* src: introduce struct nft_cacheVarsha Rao2017-08-141-2/+2
| | | | | | | | | | Pass variable cache_initialized and structure list_head as members of structure nft_cache. Joint work with Pablo Neira. Signed-off-by: Varsha Rao <rvarsha016@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* include: Pass nf_sock where needed as parameterPablo Neira Ayuso2017-07-171-2/+4
| | | | | | | | | | | | This socket should not be global, it is also hidden in many layers of code. Expose it as function parameters to decouple the netlink socket handling logic from the command parsing, evaluation and bytecode generation. Joint work with Varsha Rao.

* src: add new generic context structure nft_ctxPablo M. Bermudo Garay2017-06-261-2/+2
| | | | | | | | | | | | | The new structure nft_ctx is meant to be used as a generic container of context information. This is a preparatory patch. So at the moment the struct just carry output_ctx on his path through main.c and cli.c. Based on original idea from Eric Leblond. Signed-off-by: Pablo M.

* src: Pass stateless, numeric, ip2name and handle variables as structure members.Varsha Rao2017-06-181-2/+2
| | | | | | | | | | | | | | | | | libnftables library will be created soon. So declare numeric_output, stateless_output, ip2name_output and handle_output as members of structure output_ctx, instead of global variables. Rename these variables as following, numeric_output -> numeric stateless_output -> stateless ip2name_output -> ip2name handle_output -> handle Also add struct output_ctx *octx as member of struct netlink_ctx.
