* src: put nf_expect and nf_conntrack into dietPablo Neira Ayuso2012-01-041-6/+6
| | | | | | | | | | | | | | | | Now, struct nf_expect takes only 192 bytes, instead of 1KB. struct nf_conntrack takes 296 bytes instead of 328 bytes. The size of the nf_expect structure has been reduced by rearranging the layout of the nf_conntrack structure. For the nf_conntrack case, this removes the allocation of room for attributes that the master tuple does not use (more specifically, the NATseq bytes). This patch modifies the binary layout of struct nf_conntrack. This should not be a problem since the definition of this object is opaque (it can be only accessed via get/set API).

* src: clarify licensing terms of library (GPLv2+)Pablo Neira Ayuso2011-12-301-3/+5
| | | | | | | | | | | | | | | | This patch is *not* changing the licensing terms of this library (which was initially released under GPLv2 and later on extended to GPLv2+ after contacting all the contributors who kindly agreed to extend it to any later GPL version). Jan says: "In libnetfilter_conntrack, there are many .c files declaring GNU GPL incorporated herein by reference without telling which version(s) exactly apply. Given src/main.c for example is actually GPL-2.0+, the reference made is ambiguous." This patch should definitely clarify this. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* expect: support CTA_EXPECT_HELP_NAMEPablo Neira Ayuso2011-12-241-0/+5
| | | | | | | | This patch adds support for CTA_EXPECT_HELP_NAME. We now have the ATTR_EXP_HELPER_NAME attribute. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* expect: nfexp_snprintf displays mask and master tuple informationPablo Neira Ayuso2011-12-061-1/+4
| | | | | | | | | | | | | | | | This patch adds mask and master tuple information regarding one expectation. This information has been not shown so far. I consider that it is interesting because you can use this information to troubleshoot expectation issues. Moreover, you can know which is the master conntrack that this expectation is attached to. This extends the text-based output for `conntrack -L exp'. This can be considered a backward compatibily issue since existing tools that are parsing this interface may break. But this is not our fault, we provide an API to the conntrack table via libnetfilter_conntrack. People should use those. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* expect: fix missing parsing of master tuplePablo Neira Ayuso2011-10-271-6/+15
| | | | | | | The master tuple was not parsed. This patch also fixes an incorrect use of the exp->set field for the expectation and mask tuples. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* expect: add support for CTA_EXPECT_FLAGSPablo Neira Ayuso2010-10-071-0/+5
| | | | | | This patch allows to set the expectation flags from user-space. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* expect: add CTA_EXPECT_ZONE supportPablo Neira Ayuso2010-10-071-0/+6
| | | | | | | We also remove the reference to CTA_EXPECT_QUEUENR with was not ever pushed into Linux kernel mainline. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* src: fix warning in compilationPablo Neira Ayuso2010-10-031-1/+1
| | | | | | | | | | | This warning has been there for quite some time, fix it by relaxing the const type checking. callback.c: In function `__expect_callback': callback.c:30: warning: passing argument 2 of `__parse_expect' from incompatible pointer type ../../include/internal/prototypes.h:32: note: expected `const struct nfattr **' but argument is of type `struct nfattr **' Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* cleanup: split internal.h into several internal header filesPablo Neira Ayuso2008-07-251-1/+1
| | | | | | | This patch cleanups the internal headers by splitting them into several logical pieces. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
