* attr: remove redundant check for NULLJan Engelhardt2010-11-111-2/+2
| | | | | | | | Calling mnl_attr_parse with cb==NULL is pointless, because the function will do nothing else. Signed-off-by: Jan Engelhardt <jengelh@medozas.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

* | nlmsg: rework mnl_nlmsg_fprintfPablo Neira Ayuso2010-11-073-27/+136
| | | | | | | | | | | | | | | | This patch reworks mnl_nlmsg_fprintf. It breaks backward compatibility of this function, there was no way to improve it without doing so (and we are still in time to break thing, BTW). Signed-off-bu: Pablo Neira Ayuso <pablo@netfilter.org>

* attr: rename str_null from NULL awayJan Engelhardt2010-10-253-6/+6
| | | | | | | | | | A small little pedantism: NULL (as in, the pointer) isn't NUL (as in, the character with value zero, '\0'). I propose to rename it to strz, for the zero-terminated string (sometimes referred to as ASCIZ string, but of course C isn't tied to ASCII).

| | | | | | | groups, being a bitmask, should be unsigned; and let's also use pid_t for pid. Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
* callback: mnl_cb_run should use a void *Jan Engelhardt2010-10-222-5/+5
| | | | | | Because in most cases, it won't be a nul-terminated string :) Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
* attr: string functions should take char *Jan Engelhardt2010-10-222-4/+4
| | | | | | | | 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>

* doc: git tree update (now at netfilter.org) and fix listing in doxygenPablo Neira Ayuso2010-10-211-7/+7
| | | | | | | | 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>
* src: define MNL_SOCKET_BUFFER_SIZE to 8192ULPablo Neira Ayuso2010-10-2112-12/+16
| | | | | | | | | | | | | | | | 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."

* build: remove unneeded -dynamic -ldl -nostartfiles flagsJan Engelhardt2010-10-194-11/+1
| | | | | | | | | 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>

| | | | | | | | | | | | 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>

* skip PortID and sequence checking if zeroPablo Neira Ayuso2010-09-081-4/+13
| | | | | | | | | 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>

* socket: remove mnl_socket_sendmsg() and mnl_socket_recvmsg()Pablo Neira Ayuso2010-06-252-32/+0
| | | | | | | | 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>

* relax mnl_attr_type_valid() checkings and change errno valuePablo Neira Ayuso2010-05-098-41/+37
| | | | | | | | 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>

| | | | | | | | | | | | | 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>
