     per-netns ipv4 sysctl_tcp_mem

Might be related to this detail in the .config:

  # CONFIG_PROC_SYSCTL is not set

So former tcp_init() code does not get run?

Thanks,

Yeah, the problem is that the sysctl variables are used internally
even though CONFIG_PROC_SYSCTL is not set. This patch makes the
initialization happen in the per-netns sysctl initializer, so it will have bogus values with your config.

Let me send you a test patch shortly.
