* license: fix and add SPDX license identifiers and drop license commentsThomas Haller2020-04-161-7/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. The point is not to manually do this task, but perform some # hacked up string replacement. _cp() { /bin/cp "$@" } _cat() { /bin/cat "$@" } in_file() { local T=$(mktemp) _cp -f "$1" "$T" _cat "$T" rm -f "$T" } out_file() { local T=$(mktemp) _cat - > "$T" _cp -f "$T" "$1" rm -f "$T" } join() { _cat "$@" | awk '{ printf("%s#x#", $0)}' } unjoin() { _cat - | sed 's/#x#/\n/g' } files_all() { git ls-files | grep -v '\.png$' | grep -v '^include/linux-private/' } adjust() { NEWLINES='\(#x#\)\+' COPYRIGHTS='\(\( \* Copyright (c) 20..\(-20..\|, 20..\)\?

* include: restore linux header includes in public headersThomas Haller2017-03-021-0/+4
| | | | | | | | | The previous commits reorganized the public headers to drop includes of linux kernel headers. Restore the previous situation because otherwise the change might break compilation for users who rely on certain headers getting dragged in by libnl3.
* include: don't include kernel headers in public libnl3 headersThomas Haller2017-03-021-4/+1
| | | | | | | | | | | | | | | | | It would be desirable not to include kernel headers in our public libnl3 headers. As a test, remove all those includes, and fix compilation by explicitly including the kernel headers where needed. In some cases, that requires forward declaration for kernel structures, as we use them as part of our own headers. Realistically, we cannot drop those includes as it probalby breaks compilation for users that expect to get a certain kernel header when including a libnl3 header. So, this will not be done and the includes will be restored in the next commit. Do this step to show how it would be and to verify that we could build with such a change. The reason not to do this is backward compatibility (at compile-time).
* nl: add function nl_pickup_keep_syserr()Thomas Haller2014-11-271-0/+5
| | | | | | | | | | | | nl_pickup() converts error codes from netlink into nl error codes using nl_syserr2nlerr(). The latter function mangles different error codes to the same nl error code. Add a new function, that returns both the nl error code and the original error code. Acked-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: Thomas Haller <thaller@redhat.com>

* Add support for inet diag Netlink protocol.Joe Damato2013-07-191-0/+1
| | | | | | | | | | | | | - Inet diag allows users to gather low-level socket information. - This library provides a higher-level API for creating inetdiag requests (via idiagnl_connect and idiagnl_send_simple) and parsing the replies (via idiagnl_msg_parse). A cache is also provided (via idiagnl_msg_alloc_cache). - Request and message objects provide APIs for accessing and setting the various properties of each. - This library also allows the user to parse the inetdiag response attributes which contain information about traffic class, TOS, congestion, socket memory info, and more depending on the kernel version used. - Includes doxygen documentation.

* nl: Fix return value of nl_recvmsgs()Thomas Graf2012-05-081-0/+1
| | | | | | | | | | | | Apparently the change to have nl_recvmsgs() return the number of parsed messages broke nl_wait_for_ack() among other applications. This patch reverts to the old behaviour and provides a new function nl_recvmsgs_report() which provides the additional information for use by the cache manager and possibly other applications.

* API to issue direct GET requests to the kernelThomas Graf2011-04-111-0/+8
| | | | | | | | | Provide nl_pickup() to pick up an answer from a netlink request and parse it using the supplied parser. Add rtnl_link_get_kernel() which sends an RTM_GETLINK to the kernel to fetch a single link directly from the kernel. This can be faster than dumping the whole table, especially if lots of links are configured.
* Add nl_send_sync()Thomas Graf2011-03-251-0/+1
| | | | | Function which sends message using nl_send_auto(), frees the message and waits for ACK/error message (if auto-ack is not disabled).
* rename nl_send_auto_complete() -> nl_send_auto(), nl_auto_complete -> ↵Thomas Graf2010-11-181-1/+4
| | | | | | nl_complete_msg() Old symbols left to maintain backwards compatibility

* new feature nl_send_iovec(), nl_auto_complete() and code refactoring.Karl Hiramoto2010-03-101-0/+4
| | | | | | | | | | | | | Create new function nl_send_iovec() to be used to send multiple 'struct iovec' through the netlink socket. This will be used for NF_QUEUE, to send packet payload of a modified packet. Refactor nl_send() to use nl_send_iovec() sending a single struct iovec. Create new function nl_auto_complete() by refactoring nl_send_auto_complete(), so other functions that call nl_send may also use nl_auto_complete() Signed-off-by: Karl Hiramoto <karl@hiramoto.org>
* Declare struct ucred in handlers.h and netlink.hPavel Roskin2009-07-201-0/+2
| | | | | | Both files refer to it. The sources including those files are not guaranteed to include sys/socket.h to ensure that struct ucred is defined.

* Rename struct nl_handle to struct nl_sockThomas Graf2008-05-151-11/+11
| | | | | | | | 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.
* Break API some moreThomas Graf2008-05-141-1/+0
| | | | | Since we've broken the API anyway, remove some aliases which only exist for backwards compatibility.
* Thread-safe error handlingThomas Graf2008-05-141-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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!
