2010-10-22callback: mnl_cb_run should use a void *Jan Engelhardt
Because in most cases, it won't be a nul-terminated string :) Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
2010-10-22attr: string functions should take char *Jan Engelhardt
I do not quite see the point of using strlen in conjunction with non-string data; so let's use char * as argument types to catch misuses. Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
2010-10-22include: consistent usage of "extern"Jan Engelhardt
Signed-off-by: Jan Engelhardt <jengelh@medozas.de>

Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
2010-10-22build: fix disable_static functionalityJan Engelhardt
Small slip on my part. AC_DISABLE_STATIC must actually come before LT_INIT to have any effect. (This is even documented.) Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
2010-10-21doc: git tree update (now at netfilter.org) and fix listing in doxygenPablo Neira Ayuso
This patch update the git tree address (now at netfilter.org) and it also fixes a minor problem with the doxygen output in one of the socket helpers. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2010-10-21src: define MNL_SOCKET_BUFFER_SIZE to 8192ULPablo Neira Ayuso
Davem spotted during the Netfilter Workshop that user-space applications should use 8KB buffers for recv(). I accidentally found that NFLOG is not following this approach (in this case we're using 131072 bytes messages), we have to document this. Anyway, according to linux/netlink.h (and to complete this log message): "skb should fit one page. This choice is good for headerless malloc. But we should limit to 8K so that userspace does not have to use enormous buffer sizes on recvmsg() calls just to avoid MSG_TRUNC when PAGE_SIZE is very large."

2010-10-19Add .gitignore filesJan Engelhardt
Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
2010-10-19build: default to not build static librariesJan Engelhardt
Users wanting static libraries can just use ./configure --enable-static. Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
2010-10-19build: remove unneeded -dynamic -ldl -nostartfiles flagsJan Engelhardt
Besides that -ldl should be in _LDADD (not _LDFLAGS), I do not see any dlopen calls at all that would make the library a requirement. I also see no reason to use -Wc,-nostartfiles. Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
2010-10-19build: resolve compiler warningsJan Engelhardt
nlmsg.c: In function "mnl_nlmsg_fprintf": nlmsg.c:260:4: warning: format "%.3d" expects type "int", but argument 3 has type "size_t" Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
2010-10-19build: rebuild .pc files when configure status changedJan Engelhardt
Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
2010-10-19build: run autoupdateJan Engelhardt
Macro usage has changed over the last few years. Update it to the current specification using autoupdate(1). Manually update INCLUDES -> CPPFLAGS, because autoupdate did not catch that. Remove $(all_includes) and $(LIBS) because it is not used anywhere. Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
2010-10-19build: use subdir-objects and CC_C_OJan Engelhardt
Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
2010-10-19build: automake options should be in AM_INIT_AUTOMAKEJan Engelhardt
Automake options set in Makefile.am are not always propagated to subdirecties. Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
2010-10-19build: do not abuse AM_INIT_AUTOMAKE for autoconf optionsJan Engelhardt
Also rename the file to its standard designated name. Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
2010-10-19build: just use autoreconfJan Engelhardt
This is the recommended way to regenerate the GNU build system files these days. Signed-off-by: Jan Engelhardt <jengelh@medozas.de>

2010-09-08examples: put examples files into specific directoriesPablo Neira Ayuso
put examples files into specific directories according to the Netlink bus they work with. And minor update in the readme file Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2010-09-08skip PortID and sequence checking if zeroPablo Neira Ayuso
If the portID/sequence number that we specify is zero, we skip the sequence tracking. This is useful if we use the same socket to listen to events and to send commands and receive their result. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

2010-07-10examples: fix rtnl-set-linkPablo Neira Ayuso
This patch fixes the example that allows to set up/down the network interface. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2010-06-25socket: remove mnl_socket_sendmsg() and mnl_socket_recvmsg()Pablo Neira Ayuso
These functions are too simple wrappers that bloat the library. We can use mnl_socket_get_fd() to obtain the file descriptor and invoke message-oriented system call instead. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

commit a5f25889216411ad7492047fafe6de03b8408440 introduced a minor problem in this example. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2010-05-09relax mnl_attr_type_valid() checkings and change errno valuePablo Neira Ayuso
This patch relaxes strict attribute checkings in the example files. I have also changed the errno value, now it's EOPNOTSUPP instead of EINVAL. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2010-05-07change errno values for mnl_cb_run[2]()Pablo Neira Ayuso
This patch changes the errno value of mnl_cb_run[2]() in the following two cases: * Invalid expected portID: ESRCH. * Invalid sequence number: EPROTO. I didn't find any better generic errno value. EINVAL is reserved for malformed messages, to avoid confusions. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

2010-04-22remove references to 'generic' in header filePablo Neira Ayuso
The term 'Generic' is used in GeNetlink, we don't want any confusion with it. Better remove it. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

2010-04-22remove redudant alignment in mnl_nlmsg_size()Pablo Neira Ayuso
MNL_NLMSG_HDRLEN already provides the aligned size of the netlink header. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

2010-04-22review data types for input parameters of mnl_attr_*() functionsPablo Neira Ayuso
This patch includes the following changes: * use uint16_t for attribute types in mnl_attr_put_*() function * use uint16_t for maximun type in mnl_attr_type_valid(...) * use size_t for attribute size validation in mnl_attr_validate2(...) * use unsigned int for offset in mnl_attr_parse(...) instead of int Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2010-04-22fix mnl_attr_parse()Jozsef Kadlecsik
mnl_attr_parse does not take into account the length of the netlink message header and the offset. Thus when validating attributes, it goes over the end of the real attribute stream and catches invalid data areas.
