* Revert "src: Declare the define visibility attribute together"Pablo Neira Ayuso2017-04-141-5/+10
| | | | | | | | This reverts commit 58cb0668dc15c78cd3af9eeaedf29386e86ecac1. Prepare a new patch to keep this update consistent with libmnl. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* src: Declare the define visibility attribute togetherKhem Raj2017-04-141-10/+5
| | | | | | | | | clang ignores the visibility attribute if its not defined before the definition. As a result these symbols become hidden and consumers of this library fail to link due to these missing symbols.

* extra: use inet_ntop instead of inet_ntoaTing-Wei Lan2014-06-301-1/+5
| | | | | | | | The result of inet_ntoa() will be overwritten by the next call to inet_ntoa(), so using it twice in the same snprintf() call causes wrong result. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* src: extra: add prefix nfq_ to internal checksum functionsPablo Neira Ayuso2013-08-131-1/+1
| | | | | | | | These functions are internal and they belong to the libnetfilter_queue scope, so let's add the corresponding nfq_ prefix. Suggested-by: Florian Westphal <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
