Activity for tcplite
-
Mateusz Viste committed [r61]
tcp development in progress
-
validation of ack num during syn/ack exchange
-
moved IP internals from types.h and buildpkt.c to ip.c
-
moved udp internals from buildpkt and types.h into udp.c
-
windows updates
-
custom callback for non-tcp/udp protocols
-
tcp work in progress - acquitting received data
-
tcp/udp/icmp handlers are fed with a length info from IP header instead of the ethernet length, to avoid interpreting eth padding
-
extended test for small chunks send actions
-
sending data works (more or less)
-
ongoing TCP work (added sending, and multiple code modifications)
-
added tl_ip_routepkt()
-
extra variables
-
simplified test app
-
init_noconf() is declared through a proper header
-
fixed arp lag during dns resolution
-
added the host tool
-
tcp ticking mechanism
-
alternative init routing - tl_initnoconf(), used specifically for dhcp operations
-
mac result is fully printed out (one nibble was missing)
-
dropped dependency on the FILE interface, replaced by calls to INT 21h
-
validates that host is within local subnet
-
clean target do not try to remove MAP file (not generated any more)
-
saved a few bytes by not writing zeroes explicitely... structure is zeroed anyway so no need to
-
replaced expensive printf() calls by INT 21h,AH=9
-
compile arping in small mem model and do not generate memory map
-
DHCP client implementation works
-
compile tlcfg under small mem model
-
small memory model compatibility fix
-
dhcp work in progress
-
accept all packets if my address is 0.0.0.0 - this is required for DHCP to work
-
fixed dns timers
-
udp sockets have a configurable maxdgramsize
-
initial works on dhcp client
-
do not attempt ARP resolution for broadcast address
-
MTU validation
-
IP/mask setting implemented
-
DNS config support
-
tlcfg evolutions
-
tlcfg help screen and reorganization for future command line arguments
-
arping calls the new tl_tick() now
-
replaced htons() by tl_htons() and exposed it through tcplite.h
-
callbacks are not invoked by the packet driver anymore, but by the application-driven tl_tick(). no need to worry about interrupts any more
-
IRQs must be disabled while packet is being built, so no interrupt routine can fiddle with tl_buildpkt() at the same time
-
tcp pre-alpha code
-
tcp pre-alpha code
-
ip does not need udp headers
-
added mtu param to tl config
-
udp syntax micro-improvements
-
protocol handlers need to be registered before usage. this helps keeping the final application small so it does not pull support for protocols that are not used anyway
-
typo fix in program help
-
licensing info
-
converted source to cr/lf
-
added arping to tools
-
dns test fixed
-
implemented dns parsing so our resolver works
-
fixed udp datagram length verification
-
added a define for accessing VGA framebuffer, for debugging convenience
-
ip stack hands over ip payload instead of entire packet
-
initial import - ethernet/arp/ip/udp prototype
-
added trunk and tags directories
