* doc: discourage the use of nflog_set_nlbufsiz()Pablo Neira Ayuso2010-11-041-0/+4
| | | | | | | | | | | The default buffer size (which is one memory page) provides the best results in terms of performance. For that reason, noone should use nflog_set_nlbufsiz() to set up a higher buffer in the applications (even if this is supported by the nfnetlink_log). Davem spotted this during the Netfilter Workshop 2010. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* license: upgrade to GPLv2+Pablo Neira Ayuso2010-10-291-1/+1
| | | | | | | | This patch upgrades the license to GPLv2+. I have received an explicit ACK via email from major contributors that are Eric Leblond <eric@inl.fr> and Harald Welte <laforge@netfilter.org>. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* doc: add libnetfilter_log doxygen documentation and update copyright noticePablo Neira Ayuso2010-07-141-5/+431
| | | | | | | | | This patch adds the libnetfilter_log documentation in doxygen format. I have also added myself to the copyright header in the libnetfilter_log.c file according to my contributions available in the git repository. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* nflog: revert previous patchPablo Neira Ayuso2010-07-111-1/+1
| | | | | | This patch reverts 9c3d1b12b2ceafd92336048985fac57f048d6e19 Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* nflog: do not default to NFLOG_XML_HW in nflog_snprintf_xml()Pablo Neira Ayuso2010-07-111-1/+1
| | | | | | | | | | | | If no flags are passed to nflog_snprintf_xml(), we print: <log></log> This is not very useful but, at least, it is a way to show that nflog_snprintf_xml() is working correctly (even if no flags were passed). Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* nflog: remove `0x' from HW protocol in output of nflog_snprintf_xml()Pablo Neira Ayuso2010-07-111-2/+2
| | | | | | This patch removes the prefix `0x' of the HW protocol. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* nflog: fix HW address output in nfq_snprintf_xml()Pablo Neira Ayuso2010-07-111-3/+3
| | | | | | | | | | | | This patch fixes the output of the HW address in XML files: <src>800:800:800:800:800:</src> now it looks fine: <src>0019a917a400</src> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* nflog: consistent nflog_snprintf_xml() return value with snprintf()Pablo Neira Ayuso2010-07-111-60/+63
| | | | | | | | | | | With this patch, nflog_snprintf_xml() returns the number of characters printed. If the output was truncated, then the return value is the number of characters that would have been written if enough space had been available. This makes nflog_snprintf_xml() consistent with the behaviour of snprintf(). Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* add nflog_snprintf_xml() to output a log in XML formatPablo Neira Ayuso2010-05-251-0/+155
| | | | | | This patch adds a new function to output the packet in XML format. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* nflog: replace nfnl_talk by nfnl_query and disable sequence trackingPablo Neira Ayuso2009-02-171-6/+9
| | | | | | | | | | This patch replaces the nfnl_talk() calls by the newer nfnl_query(). This patch also disables netlink sequence tracking by default. Spurious race conditions in the sequence tracking may occur while binding to queues and high load of log messages at the same time.

* Suppress NFULNL_MSG_CONFIG callback registration.Eric Leblond2008-12-301-20/+0
| | | | | | | | It seems there is no NFULNL_MSG_CONFIG message send from kernel space to userspace. Thus the registration of an nfnetlink callback for this type of messages is not necessary. Signed-off-by: Eric Leblond <eric@inl.fr>
* Suppress reference to libnetfilter_queue which is the model of libnetfilter_log.Eric Leblond2008-12-301-7/+7
| | | | | | | | This patch fixes the description of the file was the one of libnetfilter_queue.c and it suppresses indication through out the file that it is a copy of the queue module. Signed-off-by: Eric Leblond <eric@inl.fr>
* Fix minor memory leak in nflog_close().Eric Leblond2008-12-151-1/+3
| | | | | The nflog_handle is allocated in nflog_open(). This patch adds the missing free in nflog_close().
* Add parsing function for raw hardware headerEric Leblond2008-07-171-0/+16
| | | | | | | | | | This patch adds support for the parsing of NFULA_HWTYPE, NFULA_HWHEADER, and NFULA_HWLEN part of the NFLOG message. This permits to have a ULOG like behaviour but thanks to NFULA_HWTYPE we will be able to parse the message cleanly in userspace.

* Use union to ensure proper alignmentFabian Hugelshofer2008-06-181-32/+44
| | | | | | | | This patch increases portability, but alignment is still not respected in nflog_get_*() which still leaves libnetfilter_log unusable on particular platforms. Signed-off-by: Fabian Hugelshofer <hugelshofer2006@gmx.ch>

* Introduce various API changes throughout the library stack/C=DE/ST=Berlin/L=Berlin/O=Netfilter Project/OU=Development/CN=laforge/emailAddress=laforge@netfilter.org2006-01-141-23/+44
| | | | | | | | | | | 1) make libnfnetlink dynamically allocate it's handles 2) apply that change throughout libnetfilter_* 3) add {nfq,nflog,nfct}_open_nfnl() functions that open the specific subsystem on top of an existing nfnl_handle, which is required for upcoming libnetfilter_conntrack_helper The changes break ABI and API compatibility of libnfnetlink, but don't break ABI or API compatibility of the libnetfilter_* libraries.
