upper layer protocol for Lua scripting

ulp-lua's Issues

bail out on urgent data

we shall not waste cpu cycles when there is urgent data to be read by the caller

improve README

use luamemory instead of luadata

luamemory is the natural evolution of luadata as it address many of its problems

improve testing servers

a more flexible testing server, for both user space and kernel space, is much desired.
for instance command line options for the use of non blocking processing, lua scripts to load, etc...

perfomance tests against recv() TCP_ZEROCOPY

pool_recycle() is raising kernel panics

rename setsockopt options

dangling pointer in timewait socket

we are panicking in timedwait sockets release process.
this issue is only reproducible when we remove the kernel module.

provide examples

improve and understand errno handling by the stdlibc

add support for udp

process.lua is returning a runtime error

with the new allocator the process.lua script is raising a runtime error

add luarocks specification

evaluate integration with AF_XDP

make implementation latency protected

add lua binding for common c side operations

a Lua binding for some kernel functions is needed.
so far:
sendmsg -> we must be able to send cached/dynamic messages from the lua scripts.
tcp_fin -> sometimes a graceful connection close is desired instead of the abrupt RST. Note that this function is slow. (What should we return to user space?)
later we can use/port open source lua libraries

add limitations to README

investigate integration with tls in kernel

improve getsockopt() and setsockopt()

we shall add more customization options through {get,set}sockopt()

wrap potentially harmful code around pcall

we shall prevent the kernel module from oops when interacting with the Lua C API

add lua_State pool

for asynchronous processing we must have a Lua state pool.
it should be configurable via setsockopt().

provide extensive perfomance results

investigate possible TCP-RST DoS

fuzzing with pktgen

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/networking/pktgen.txt?h=v5.0-rc2

improve sk_buff fragments treatment in recvmsg()

if we don't GRO we may have trouble when performing L4 inspection on the sk_buff fragments in the receive queue.

we shall extensively test against real world cases

add support for ipv6

we shall investigate and add support for ipv6

split module.c

I intend to split the module.c into other .cs, each system call will have it's own .c, like in libcs implementations.

memory allocator reports no memory in high traffic

patch Lua with buffer support
