php is requesting tcpi_sacked from tcp info.
this is a quick fix, as we can just set it to 0 to pretend being linux 2.4

should i PR?

The networking stack is being completely rewritten, I wouldn't want to introduce new feature and/or change much code in the meantime.

nginx in enclave:

    - do not fork workers due to gramineproject/gramine#468 (also generally dont)
    - use select instead of epoll due to gramineproject/gramine#489
    - link pcre static due to undetermined dynloader bug

php in enclave:

    - patch away sockopt SO_LISTENQLEN and TCP_INFO due to gramineproject/gramine#503
    - do not fork workers
    - manually force linking libm static, because the ld loader implements glibc versions incorrectly
    - remove apparmor from AC

wordpress in enclave:

    - installer loads fine but needs mysql server to proceed

#579 rewrites the socket stack. After it's merged (which hopefully will happen, I would estimate in two weeks), we can start accepting PRs modifying that code.

But I must say, we cannot really pretend we are linux 2.4, we already present some info about versions (and they are higher than that).

@aep The networking stack was rewritten. If you still need this/want this, please submit a PR.
