QUESTION

Netfilter hook stateful connection packet filtering

Asked 2021-Feb-18 at 18:21

I am writing a Netfilter hook and want to do a stateful analysis of incoming TCP packets, whether they belong to an existing connection or a new connection is starting. This is my first try at writing code using Netfilter and after reading https://people.netfilter.org/pablo/docs/login.pdf I understand I need to check if a packet is categorized as a NEW or ESTABLISHED state. But I cannot find any documentation of how to write code for this.

Seems that in your hook you want to make a decision on packet based on conntrack(CT) info about the connection state - to block (drop) all the TCP packets which are in the middle of connection, i.e. packets both without SYN flag and without connection entry in CT.

So if you want to reap the benefits of CT, you have to let him work a bit.
Now your hook is in NF_INET_PRE_ROUTING with NF_IP_PRI_FIRST priority. Just look at the picture of Linux kernel packet flow. If we talk about pre-routing chain CT-handling is somewhere after RAW table (i.e. with a lower priority).
The list of priorities you can see here:

Answered 2018-Jun-21 at 01:32

Here's my understanding of why the outputs are seen:

A42 is working as expected because i is equal to 42
B431891052 because the pointer void* d is not initialized, and may be containing a garbage value, and the print statement printf("B%d",d) just prints the lower 32 bits of it.
C-288453328 because the statement printf("C%d",s) prints the lower 32 bits of variable i. In 32 bits the number -288453328 corresponds to hexadecimal number 0xEECE8D30; I think it's the lower 32 bits of the stack address 0x7FFFEECE8D30.
D1 because the hr will contain whatever first 8 bytes dr is point to. It is uninitialized, and in this example the value it points to happens to be 1.

I think to assign have D12 the function memManageC may need to be changed to the following:

If all you want is the conversion (and not necessarily macro), shapeless provides these out of the box as extension methods on functions:
