netfilter: nf_conntrack_sip: fix expectation clash
When conntracks change during a dialog, SDP messages may be sent from different conntracks to establish expects with identical tuples. In this case expects conflict may be detected for the 2nd SDP message and end up with a process failure.
The fixing here is to reuse an existing expect who has the same tuple for a different conntrack if any.
Here are two scenarios for the case.
1) SERVER CPE
| INVITE SDP | 5060 |<----------------------|5060 | 100 Trying | 5060 |---------------------->|5060 | 183 SDP | 5060 |---------------------->|5060 ===> Conntrack 1 | PRACK | 50601 |<----------------------|5060 | 200 OK (PRACK) | 50601 |---------------------->|5060 | 200 OK (INVITE) | 5060 |---------------------->|5060 | ACK | 50601 |<----------------------|5060 | | |<--- RTP stream ------>| | | | INVITE SDP (t38) | 50601 |---------------------->|5060 ===> Conntrack 2
With a certain configuration in the CPE, SIP messages "183 with SDP" and "re-INVITE with SDP t38" will go through the sip helper to create expects for RTP and RTCP.
It is okay to create RTP and RTCP expects for "183", whose master connection source port is 5060, and destination port is 5060.
In the "183" message, port in Contact header changes to 50601 (from the original 5060). So the following requests e.g. PRACK and ACK are sent to port 50601. It is a different conntrack (let call Conntrack 2) from the original INVITE (let call Conntrack 1) due to the port difference.
In this example, after the call is established, there is RTP stream but no RTCP stream for Conntrack 1, so the RTP expect created upon "183" is cleared, and RTCP expect created for Conntrack 1 retains.
When "re-INVITE with SDP t38" arrives to create RTP&RTCP expects, current ALG implementation will call nf_ct_expect_related() for RTP and RTCP. The expects tuples are identical to those for Conntrack 1. RTP expect for Conntrack 2 succeeds in creation as the one for Conntrack 1 has been removed. RTCP expect for Conntrack 2 fails in creation because it has idential tuples and 'conflict' with the one retained for Conntrack 1. And then result in a failure in processing of the re-INVITE.
2)
SERVER A CPE
| REGISTER | 5060 |<------------------| 5060 ==> CT1 | 200 | 5060 |------------------>| 5060 | | | INVITE SDP(1) | 5060 |<------------------| 5060 | 300(multi choice) | 5060 |------------------>| 5060 SERVER B | ACK | 5060 |<------------------| 5060 | INVITE SDP(2) | 5060 |-------------------->| 5060 ==> CT2 | 100 | 5060 |<--------------------| 5060 | 200(contact changes)| 5060 |<--------------------| 5060 | ACK | 5060 |-------------------->| 50601 ==> CT3 | | |<--- RTP stream ---->| | | | BYE | 5060 |<--------------------| 50601 | 200 | 5060 |-------------------->| 50601 | INVITE SDP(3) | 5060 |<------------------| 5060 ==> CT1
CPE sends an INVITE request(1) to Server A, and creates a RTP&RTCP expect pair for this Conntrack 1 (CT1). Server A responds 300 to redirect to Server B. The RTP&RTCP expect pairs created on CT1 are removed upon 300 response.
CPE sends the INVITE request(2) to Server B, and creates an expect pair for the new conntrack (due to destination address difference), let call CT2. Server B changes the port to 50601 in 200 OK response, and the following requests ACK and BYE from CPE are sent to 50601. The call is established. There is RTP stream and no RTCP stream. So RTP expect is removed and RTCP expect for CT2 retains.
As BYE request is sent from port 50601, it is another conntrack, let call CT3, different from CT2 due to the port difference. So the BYE request will not remove the RTCP expect for CT2.
Then another outgoing call is made, with the same RTP port being used (not definitely but possibly). CPE firstly sends the INVITE request(3) to Server A, and tries to create a RTP&RTCP expect pairs for this CT1. In current ALG implementation, the RTCP expect for CT1 fails in creation because it 'conflicts' with the residual one for CT2. As a result the INVITE request fails to send.

netfilter: nf_conntrack_amanda: add support for STATE streams
The Amanda CONNECT command has been updated to establish an optional fourth connection [0]. Previously, a CONNECT command would look like:
CONNECT DATA port0 MESG port1 INDEX port2
nf_conntrack_amanda analyses the CONNECT command string in order to learn the port numbers of the related DATA, MESG and INDEX streams. As of amanda v3.4, the CONNECT command can advertise an additional port:
CONNECT DATA port0 MESG port1 INDEX port2 STATE port3
The new STATE stream is not handled, thus the connection on the STATE port cannot be established.
The patch adds support for STATE streams to the amanda conntrack helper.
I tested with max_expected = 3, leaving the other patch hunks unmodified. Amanda reports "connection refused" and aborts. After I set max_expected to 4, the backup completes successfully.

Also introduce h323_helper_init/exit helper function to register the ct helpers, this is prepared for the followup patch, which will add net namespace support for ct helper.

netfilter: helper: add build-time asserts for helper data size
add a 32 byte scratch area in the helper struct instead of relying on variable sized helpers plus compile-time asserts to let us know if 32 bytes aren't enough anymore.
Not having variable sized helpers will later allow to add BUILD_BUG_ON for the total size of conntrack extensions -- the helper extension is the only one that doesn't have a fixed size.
The (useless!) NF_CT_HELPER_BUILD_BUG_ON(0); are added so that in case someone adds a new helper and copy-pastes from one that doesn't store private data at least some indication that this macro should be used somehow is there...

However, depending on the helper, there are different reasons why a packet can be dropped.
This patch modifies the existing code to provide more specific error message in the scope of each helper to help users to debug the reason why the packet has been dropped, ie:
nf_ct_%s: dropping packet: reason ...
Thanks to Joe Perches for many formatting suggestions.

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies.
percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion.
http://userweb.kernel.org/~tj/misc/slabh-sweep.py
The script does the followings.
* Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h.
* When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order.
* If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file.
The conversion was done in the following steps.
1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files.
2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files.
3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind.
4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually.
5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary.
6. percpu.h was updated not to include slab.h.
7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq).
* x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig
8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point.
Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

[NETFILTER]: nf_conntrack: introduce expectation classes and policies
Introduce expectation classes and policies. An expectation class is used to distinguish different types of expectations by the same helper (for example audio/video/t.120). The expectation policy is used to hold the maximum number of expectations and the initial timeout for each class.
The individual classes are isolated from each other, which means that for example an audio expectation will only evict other audio expectations.
