* all: cleanup includes and use "nm-default.h"Thomas Haller2023-08-021-2/+6

* include: split and drop "netlink-private/types.h"Thomas Haller2023-08-021-0/+2
| | | | | Move all the declarations from "netlink-private/types.h" to places closer to where they are used.
* route: merge "include/netlink-private/tc.h" to lib/route/tc-api.hThomas Haller2023-08-011-1/+0
| | | | | It's a private header only for lib/route (libnl-route-3). We already have a similar header. Move the content to "lib/route/tc-api.h".
* all: avoid coverity warnings about assigning variable but not using itThomas Haller2022-04-221-2/+2
| | | | | | | | | | | | Workaround coverity warnings like: Error: CLANG_WARNING: libnl-3.6.0/lib/netfilter/exp.c:428:7: warning[deadcode.DeadStores]: Although the value stored to 'err' is used in the enclosing expression, the value is never actually read from 'err' # 426| } # 427|··· # 428|-> if ((err = nfnl_exp_build_tuple(msg, exp, CTA_EXPECT_NAT)) < 0) # 429| goto nla_put_failure; # 430|···
* 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..\(-20..\|, 20..\)\?

* all: Avoid pointer arithmetic on `void *`Michael Forney2019-08-161-1/+1
| | | | | | | ISO C requires that the pointer operand to the binary + operator be to a complete object type[0]. [0] http://port70.net/~nsz/c/c11/n1570.html#6.5.6p2
* Add support for cloning cgroup filter object.d0u92018-06-251-0/+57
| | | | | | | | | | | In this commit, we implement ematch_tree_clone(), which is basis of cgroup_clone() interface. The whole ematch tree is deep-copied except the e_ops filed. Also, a new unit test is added for testing the interface, which named as check-ematch-tree-clone.c located in tests directory. https://github.com/thom311/libnl/pull/176
* include: don't include kernel headers in public libnl3 headersThomas Haller2017-03-021-0/+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).
* cls: fix array overrun in rtnl_ematch_opnd2txt()Thomas Haller2014-06-101-1/+1
| | | | | | | Error found by coverity. Acked-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: Thomas Haller <thaller@redhat.com>
* route: remove unnecessary non-null check in pktloc and ematchThomas Haller2014-06-101-3/+1
| | | | | | | | This check is not necessary, and also they cause coverity to complain. Acked-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: Thomas Haller <thaller@redhat.com>
* lib: reorder free() after printf("%p") statementsThomas Haller2014-06-101-1/+2
| | | | | | | | | | Previously coverity was complaining about a use-after-free. This was not a real problem, because the printf statement does not dereferenciate the pointer. Change it to avoid the warning. Acked-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: Thomas Haller <thaller@redhat.com>
* Move private header files to <netlink-private/*>Thomas Graf2013-01-241-3/+3
| | | | | | | This clarifies the seperation between public and private header files. Signed-off-by: Thomas Graf <tgraf@suug.ch>
* Unified TC APIThomas Graf2011-03-211-1/+3
| | | | | | | | Finally got rid of all the qdisc/class/cls code duplication in the tc module API. The API takes care of allocation/freeing the tc object specific data. I hope I got it right this time.
* Support for meta matchThomas Graf2010-10-311-0/+14

* Tons of ematch workThomas Graf2010-10-281-59/+319
| | | | | | | | | | - Fixes a bunch of bugs related to ematches - Adds support for the nbyte ematch - Adds a bison/flex parser for ematch expressions, expressions may look like this: ip.length > 256 && pattern(ip6.src = 3ffe::/16) documenation on syntax follows - adds ematch support to the basic classifier (--ematch EXPR)
* - Reworked the classifier interface.Thomas Graf2009-09-021-0/+410
- Added initial ematch support - Added support for the basic classifier - Added support for the cgroup classifier
