* all: fix and enable "-Wsign-compare" warningThomas Haller2024-05-291-1/+1

* all: cleanup includes and use "nm-default.h"Thomas Haller2023-08-021-2/+3

* genl: rename private header "nl-priv-genl.h" to "nl-genl.h"Thomas Haller2023-08-021-1/+1
| | | | | | The filename is still unique (which is the important part). Otherwise, the "priv" is redundant, since the header being inside "lib/genl" is clearly private.
* genl: add comment about wrongly exported symbol genl_resolve_id()Thomas Haller2023-07-311-0/+1
|
* include: move "include/netlink-private/genl.h" to "lib/genl/nl-priv-genl.h"Thomas Haller2023-07-311-1/+1
| | | | | | | | | | This header is entirely private to the source files in "lib/genl". It's confusing to keep it separate. Place it beside the source files, which can use it. I guess, I just disagree with this notion, that all headers must be under "include/" directory. Not, if the header is entirely local to one module.
* base: move "netlink-private/utils.h" to "base/nl-base-utils.h"Thomas Haller2023-07-311-1/+1
| | | | | | | | | | "base/nl-base-utils.h" (formerly "netlink-private/utils.h") contains no libnl3 specific references, just a bunch of C helpers. It's also a header-only "library", so it can be freely used by all our C-code. Move it to a separate directory, to make that clear.
* license: fix and add SPDX license identifiers and drop license commentsThomas Haller2020-04-161-7/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This also fixes a few wrong SPDX license identifiers, where the original license comment indicates GPL-2.0-only. This is not done manually, but by running the following script: --- #!/bin/bash # Tool to drop license comments, adding SPDX license identifiers, while preserving # copyright comments.

* lib: use _nl_strncpy*() instead of plain strncpy()Thomas Haller2020-04-151-2/+2
| | | | | | | | | | | | | | | | There wasn't really a bug previously, but it's ugly and raises questions about the correct use of strncpy(). For example, void genl_family_set_name(struct genl_family *family, const char *name) { strncpy(family->gf_name, name, GENL_NAMSIZ-1); was in fact correct, because family->gf_name will (presumably) always have a NUL character as last position. Still use _nl_strncpy*() wrappers, to avoid raising such questions.

* lib/genl: avoid VLA in cmd_msg_parser()Thomas Haller2019-08-091-20/+26
| | | | | | | | | We want to build with -Wvla, because VLAs interfere with static asserts (if the condition of a static assert is not actually static, then VLAs make it silently pass). Also, VLAs should be avoided because we want to be in contol how much we allocate on the stack.
* genl: drop usage of GENL_ID_GENERATETobias Klauser2017-05-291-1/+1
| | | | | | | | | | | | After kernel commit a07ea4d9941a ("genetlink: no longer support using static family IDs"), GENL_ID_GENERATE is no longer exposed to userspace (and actually should never have been). Update the private header copy of linux/genetlink.h accordingly. And replace the two occurences of GENL_ID_GENERATE.

* genl: Update mt_id of cache ops when resolving genl idThomas Graf2013-04-011-0/+4
| | | | | | | | | | | | The cache layer uses the message type array stored in the cache ops to lookup which cache a message belongs to. Update to the the message array with the resolved generic netlink id to make it compatible with the caching API. Allows to use nl_cache_refill() and others for generic netlink based caches with dynamic generic netlink ids. Signed-off-by: Thomas Graf <tgraf@suug.ch>
* genl: Provide internal function to resolve name to idThomas Graf2013-04-011-0/+26

* Move private header files to <netlink-private/*>Thomas Graf2013-01-241-1/+1

* genl: Support registration of families without depending on cachesThomas Graf2012-06-011-34/+161
| | | | | | | | | | | | Introduces the functions genl_register_family() and genl_unregister_family() to register a Generic Netlink family which does not implement a cachable type. API users can direct received messages into genl_handle_msg() which will validate the messages and call the callback functions defined in the commands definition. See test/test-genl.c for an example on how to use it.
* genl: Add genlmsg_user_hdr(), genlmsg_user_data(), and genlmsg_user_datalen()Thomas Graf2012-05-311-1/+1
| | | | | | | These functions deprecate the function genlmsg_data() which did not allow to specify the length of the user header. Use of the new API will make code much clearer. The old function is still kept around for backwards compatibility but marked deprecated in the API reference.

* Rename struct nl_handle to struct nl_sockThomas Graf2008-05-151-4/+4
| | | | | | | | The idea of a common handle is long revised and only misleading, nl_handle really represents a socket with some additional action handlers assigned to it. Alias for nl_handle is kept for backwards compatibility.
* Thread-safe error handlingThomas Graf2008-05-141-21/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order for the interface to become more thread safe, the error handling was revised to no longer depend on a static errno and error string buffer. This patch converts all error paths to return a libnl specific error code which can be translated to a error message using nl_geterror(int error). The functions nl_error() and nl_get_errno() are therefore obsolete. This change required various sets of function prototypes to be changed in order to return an error code, the most prominent are: struct nl_cache *foo_alloc_cache(...); changed to: int foo_alloc_cache(..., struct nl_cache **); struct nl_msg *foo_build_request(...); changed to: int foo_build_request(..., struct nl_msg **); struct foo *foo_parse(...); changed to: int foo_parse(..., struct foo **); This pretty much only leaves trivial allocation functions to still return a pointer object which can still return NULL to signal out of memory. This change is a serious API and ABI breaker, sorry!
* Export interface to define cachesThomas Graf2007-09-171-2/+2
| | | | | | | | | | This interface was internal so far which required all code defining caches to be compiled with the sources available. In order to simplify the interface, the co_msg_parser prototype was changed to take the struct nl_parser_param directly instead of a void *. It used to be void * because the co_msg_parser was directly passed as the NL_CB_VALID callback function.
