productive aka practicing guitar meme

flint idol Feb 7, 2025, 5:19 PM

#

Anyway I will be back with news on this soon™️

#

About 3-5 pm EST

#

If I do rewrite the first thing I am doing is making a good naming convention

#

Rather, a better naming convention

#

Will probably just be snake case or smth

main girder Feb 7, 2025, 5:21 PM

#

do the mica naming convention

real pecan Feb 7, 2025, 5:21 PM

#

do astral naming convention

main girder Feb 7, 2025, 5:21 PM

#

main girder do the mica naming convention

facility$verb_noun

lean glen Feb 7, 2025, 5:21 PM

#

the NT naming convention is pretty nice

main girder Feb 7, 2025, 5:21 PM

#

the dollar signs mean its cool

flint idol Feb 7, 2025, 5:22 PM

#

main girder `facility$verb_noun`

Funny how dollar signs are legal iirc in C identifiers

main girder Feb 7, 2025, 5:22 PM

#

yes

timid elk Feb 7, 2025, 5:22 PM

#

they are

lean glen Feb 7, 2025, 5:22 PM

#

main girder `facility$verb_noun`

that's mine but using namespaces meme

timid elk Feb 7, 2025, 5:22 PM

#

serenityos and some other os uses sys$name for syscalls

main girder Feb 7, 2025, 5:22 PM

#

this surprises ppl but its because of DEC who used $ everywhere and it was to avoid precluding using C on their OSes

main girder Feb 7, 2025, 5:22 PM

#

timid elk serenityos and some other os uses sys$name for syscalls

for serenity's case its a weird larp

timid elk Feb 7, 2025, 5:22 PM

#

yep

main girder Feb 7, 2025, 5:22 PM

#

i have no idea why they randomly use $ for that

timid elk Feb 7, 2025, 5:22 PM

#

they don't need it

flint idol Feb 7, 2025, 5:22 PM

#

Also maybe I will use a different language...

timid elk Feb 7, 2025, 5:22 PM

#

they are literally cpp

#

they have namespaces

haughty abyss Feb 7, 2025, 5:23 PM

#

yeah lol

haughty abyss Feb 7, 2025, 5:23 PM

#

flint idol Funny how dollar signs are legal iirc in C identifiers

as a GNU extension

#

its nonstandard

real pecan Feb 7, 2025, 5:24 PM

#

flint idol Also maybe I will use a different language...

lol which

flint idol Feb 7, 2025, 5:24 PM

#

Uh I also know C++

#

Unless I choose to learn zig

real pecan Feb 7, 2025, 5:24 PM

#

if u do c++ u can use qacpi LETSFUCKINGGOOOOOO

flint idol Feb 7, 2025, 5:24 PM

#

flint idol Uh I also know C++

Yeah no I'll just use C in that case

flint idol Feb 7, 2025, 5:24 PM

#

real pecan if u do c++ u can use qacpi <:LETSFUCKINGGOOOOOO:1003833035688513606>

Lol

white mulch Feb 7, 2025, 5:25 PM

#

KEKW

flint idol Feb 7, 2025, 5:25 PM

#

My naming convention might copy snake_case or be the NtNamingConvention

#

If I do rewrite of course

real pecan Feb 7, 2025, 5:25 PM

#

whatever u do dont do tabs BlessRNG

haughty abyss Feb 7, 2025, 5:26 PM

#

why? tabs are great

flint idol Feb 7, 2025, 5:26 PM

#

Like the indentation thing?

real pecan Feb 7, 2025, 5:26 PM

#

lmfao this discussion again

haughty abyss Feb 7, 2025, 5:26 PM

#

real pecan if u do c++ u can use qacpi <:LETSFUCKINGGOOOOOO:1003833035688513606>

oh thats great for shkwve v2 now with more C++!

real pecan Feb 7, 2025, 5:26 PM

#

flint idol Like the indentation thing?

yes

flint idol Feb 7, 2025, 5:26 PM

#

Yeah

haughty abyss Feb 7, 2025, 5:26 PM

#

tabs are objectively better because you can set it to what you want them to be as a user

flint idol Feb 7, 2025, 5:26 PM

#

I am going to use spaces

flint idol Feb 7, 2025, 5:26 PM

#

haughty abyss tabs are objectively better because you can set it to what you want them to be a...

Who is the user of obos?

haughty abyss Feb 7, 2025, 5:27 PM

#

flint idol Who is the user of obos?

any other developers

#

lol

real pecan Feb 7, 2025, 5:27 PM

#

me 🙂

flint idol Feb 7, 2025, 5:27 PM

#

I'll see what I will do

#

Also maybe this is all bait to get the obos thread alive because I am lonely meme

real pecan Feb 7, 2025, 5:28 PM

#

anyway u can try zig

#

ig

flint idol Feb 7, 2025, 5:28 PM

#

Sounds like C but on steroids

#

So I might as well use C in that case

real pecan Feb 7, 2025, 5:28 PM

#

like C but your program gets optimized away

lean glen Feb 7, 2025, 5:28 PM

#

haughty abyss oh thats great for shkwve v2 now with more C++!

are you rewriting it in C++?

haughty abyss Feb 7, 2025, 5:28 PM

#

lean glen are you rewriting it in C++?

yeah

#

lol

flint idol Feb 7, 2025, 5:28 PM

#

flint idol So I might as well use C in that case

All options go back to C

lean glen Feb 7, 2025, 5:28 PM

#

zig sucks, I'd honestly just pick C

lean glen Feb 7, 2025, 5:28 PM

#

haughty abyss yeah

use my libraries chad

real pecan Feb 7, 2025, 5:28 PM

#

how

haughty abyss Feb 7, 2025, 5:28 PM

#

yeah zig sucks

white mulch Feb 7, 2025, 5:29 PM

#

I think I have tried zig like once, I don't exactly remember why I didn't use it more

lean glen Feb 7, 2025, 5:29 PM

#

haughty abyss yeah

so is it a bootloader or a firmware thing

#

because

#

if its a firmware thing

haughty abyss Feb 7, 2025, 5:29 PM

#

lean glen so is it a bootloader or a firmware thing

probably maybe both idk yet

flint idol Feb 7, 2025, 5:29 PM

#

Gtg now

lean glen Feb 7, 2025, 5:29 PM

#

I could contribute

haughty abyss Feb 7, 2025, 5:30 PM

#

would love contributors

lean glen Feb 7, 2025, 5:30 PM

#

so it boots my OS

haughty abyss Feb 7, 2025, 5:30 PM

#

so far i wrote a horribly overcomplicated print function

#

and some async shit

lean glen Feb 7, 2025, 5:30 PM

#

we can use my libraries

#

library rather

haughty abyss Feb 7, 2025, 5:30 PM

#

for DT? yeah maybe

lean glen Feb 7, 2025, 5:30 PM

#

no for the general stuff

#

its like frigg

#

but better

haughty abyss Feb 7, 2025, 5:30 PM

ah

#

yk the rusty thing

timid elk Feb 7, 2025, 6:49 PM

#

haughty abyss tabs are objectively better because you can set it to what you want them to be a...

you can do the same for spaces

#

if you can't, your editor sucks

haughty abyss Feb 7, 2025, 6:50 PM

#

timid elk you can do the same for spaces

huh no you can't?

#

space width is not a display option

timid elk Feb 7, 2025, 6:50 PM

#

it is in my editor (doom emacs and very rarely vscode)

#

any good editor does it

#

detects indentation and makes it render as your indentation size

#

i believe even vim has it but my vim config is very barebones

#

all that matters is tabs are literally the worst thing ever

#

most stuff default to 8 em size tabs (e.g. github) and it's such an eyesore

#

and tabs weren't meant to be a fixed size

#

they align to the next multiple of 8

#

you're not supposed to make them 4 or 2 characters long

#

we have a tool for that, spaces

#

tabs have a specific reason to exist and there's no reason why they should do the job of spaces

white mulch Feb 7, 2025, 6:57 PM

#

timid elk they align to the next multiple of 8

💀

timid elk Feb 7, 2025, 6:58 PM

#

that's literally their standard behaviour

white mulch Feb 7, 2025, 6:58 PM

#

reminds me of gnu braindead style

timid elk Feb 7, 2025, 6:58 PM

#

what's that

white mulch Feb 7, 2025, 6:58 PM

#

they replace every 8 spaces with a tab

haughty abyss Feb 7, 2025, 6:59 PM

#

timid elk it is in my editor (doom emacs and very rarely vscode)

holy shit what the fuck

timid elk Feb 7, 2025, 6:59 PM

#

white mulch they replace every 8 spaces with a tab

ok that's braindead

#

just use spaces

white mulch Feb 7, 2025, 6:59 PM

#

or tabs

timid elk Feb 7, 2025, 6:59 PM

#

spaces!!

flint idol Feb 7, 2025, 6:59 PM

#

Spaces ftw

timid elk Feb 7, 2025, 7:00 PM

#

what are you optimising for? source code size??

white mulch Feb 7, 2025, 7:00 PM

#

I just like tabs more, I don't like being able to click in the middle of indent meme

timid elk Feb 7, 2025, 7:00 PM

#

haughty abyss holy shit what the fuck

why is that a wtf

timid elk Feb 7, 2025, 7:00 PM

#

white mulch I just like tabs more, I don't like being able to click in the middle of indent ...

you.can.congifure.taht

haughty abyss Feb 7, 2025, 7:00 PM

#

this is very much not what i would expect

#

tbh

#

also that cant always render correctly

timid elk Feb 7, 2025, 7:01 PM

#

you guys probably like elastic tabstops too

haughty abyss Feb 7, 2025, 7:01 PM

#

there is no way to know what the user intended

white mulch Feb 7, 2025, 7:01 PM

#

timid elk you.can.congifure.taht

maybe but eh, idrc use whatever you want, I will keep using tabs

timid elk Feb 7, 2025, 7:01 PM

#

time to fork mlibc to use spaces

haughty abyss Feb 7, 2025, 7:01 PM

#

tbh i just like using a character intended for indendation to indent things

#

lol

timid elk Feb 7, 2025, 7:02 PM

#

space is intended

haughty abyss Feb 7, 2025, 7:02 PM

#

uh, no

#

a space is intended strictly for separating words

white mulch Feb 7, 2025, 7:02 PM

#

average indentation war

timid elk Feb 7, 2025, 7:02 PM

#

tab is for aligning to multiples of 8 which doesn't make sense in a programming context

#

then there's elastic tabstops...

haughty abyss Feb 7, 2025, 7:03 PM

#

timid elk tab is for aligning to multiples of 8 which doesn't make sense in a programming ...

its not for multiples of 8?

#

it never was

timid elk Feb 7, 2025, 7:03 PM

#

it is!!

haughty abyss Feb 7, 2025, 7:03 PM

#

ok

#

it once was

#

but its not for like

#

a looooong time

timid elk Feb 7, 2025, 7:03 PM

#

not multiple of 8 indentation, ALIGNING to multiples of 8

haughty abyss Feb 7, 2025, 7:03 PM

#

because of variable width fonts

haughty abyss Feb 7, 2025, 7:03 PM

#

timid elk not multiple of 8 indentation, ALIGNING to multiples of 8

yes.

timid elk Feb 7, 2025, 7:03 PM

#

and every non-code editor will do that

haughty abyss Feb 7, 2025, 7:03 PM

#

it doesnt align to multiples of 8

white mulch Feb 7, 2025, 7:03 PM

#

any sane editor doesn't have align to 8 by default

haughty abyss Feb 7, 2025, 7:03 PM

#

every non-code editor aligns to the next tabstop which is not necessarily 8 anythings

#

padding
12345
b

#

please tell me this is 8

#

lol

#

oh wait

#

its spaces

timid elk Feb 7, 2025, 7:04 PM

#

e.g. 2 space + 1 tab makes 8 spaces

haughty abyss Feb 7, 2025, 7:04 PM

#

ah

#

discord converts tabs to spaces

#

of course

haughty abyss Feb 7, 2025, 7:04 PM

#

timid elk e.g. 2 space + 1 tab makes 8 spaces

uh no

timid elk Feb 7, 2025, 7:04 PM

#

discord based

timid elk Feb 7, 2025, 7:04 PM

#

haughty abyss uh no

open notepad rn

#

i mean visually

#

not actually 8 spaces

haughty abyss Feb 7, 2025, 7:04 PM

#

here is google docs:

haughty abyss here is google docs:

^^ renders like this in both chrome and firefox for me

#

and this is also the correct rendering

#

because a space is significantly smaller than most letters

timid elk Feb 7, 2025, 7:07 PM

#

firefox

#

it's google docs fuckup not mobile fuckup

just try a bare html file

#

wait

haughty abyss Feb 7, 2025, 7:08 PM

#

it would

timid elk Feb 7, 2025, 7:08 PM

#

ok bare text file ig

haughty abyss Feb 7, 2025, 7:09 PM

timid elk it's google docs fuckup not mobile fuckup

actually its probably because your screen is super tiny

timid elk Feb 7, 2025, 7:09 PM

nah

#

it's because mobile web google docs isn't full google docs

flint idol Feb 7, 2025, 7:09 PM

#

ah maybe okay

timid elk Feb 7, 2025, 7:09 PM

yeah fair

#

its a mobile gdocs skill issue

timid elk Feb 7, 2025, 7:10 PM

#

yay

#

and in gdocs tab size is configurable

haughty abyss Feb 7, 2025, 7:10 PM

#

that does in fact make sense

#

every good editor has that

#

lol

timid elk Feb 7, 2025, 7:11 PM

#

and afaik it turns tab characters into paragraph starts or whatever

haughty abyss Feb 7, 2025, 7:11 PM

no i dont think so

timid elk Feb 7, 2025, 7:11 PM

#

that WYSIWYG indentation thing

haughty abyss Feb 7, 2025, 7:11 PM

separate thing

flint idol Feb 7, 2025, 7:11 PM

Thanks for hijacking my thread

timid elk Feb 7, 2025, 7:11 PM

when it's at a newline it does that i think

#

rename the thread to indentation war

haughty abyss Feb 7, 2025, 7:11 PM

((not really, most people here would pick limine))

#

okay I'll ping infy and mintsuki
I will use the bootloader of the first one to answer trl

#

(/j)

#

I'm gonna use C23 because it sounds cool

#

okay so my naming convention will probably just be snake case

I'll have a few "namespaces"

I guess

so the only levels are dispatch, all-except-timers and timers and ipi probably

Yes

I've got an old and well worn copy of Windows(r) Internals lying around somewhere. I read it a while back and have already forgotten a lot of things

main girder Feb 9, 2025, 10:07 PM

#

split rampart it's a pretty specific thing in the Windows kernel

ya generally speaking theres like two layers, the kernel (Ke) and the executive (everything else)

#

Ke is the inner layer and it contains like the scheduler and exception handling and whatever

#

the executive is literally everything else

#

its just a convention thing basically like Ke isnt allowed to allocate memory or call up into the executive (except when it does because thats the less ugly option than some alternative)

flint idol Feb 9, 2025, 10:10 PM

#

main girder why would that go in Ke

Idk where it would go

#

I thought Rtl

split rampart Feb 9, 2025, 10:10 PM

main girder its just a convention thing basically like Ke isnt allowed to allocate memory or...

sounds reasonable

rtl?

which is like runtime stuff u can share between kernel and usermode

split rampart Feb 9, 2025, 10:17 PM

I wouldn't have thought for two days where to stick the print functions and would have just done kprintf and moved on

main girder Feb 9, 2025, 10:18 PM

#

mine is in rtl but when i say that i mean its sharable between user and kernel mode so i dont have to copypaste it later.

split rampart Feb 9, 2025, 10:19 PM

#

well, either you know your stuff and do it right from the start, or you dont sit still and after 100 iterations get the result you need

#

99.9% you don’t know, so you sit there and redo it

imo printing is definitely not worth the time, it’s easy to change

Well, that's because you work alone and I'm sure you're deluded (you work alone?)

wdym deluded LOL

split rampart Feb 9, 2025, 10:24 PM

#

imagine you’re given task X. Either you can do it right away if you know your stuff, but tbh that requires some serious experience. Otherwise, you'll be reworking it until your manager approves the solution, and it satisfies everyone involved

split rampart Feb 9, 2025, 10:25 PM

#

main girder wdym deluded LOL

It's about knowing what to do and doing it right the first time

#

But that's almost never the case in a project with people who do reviews and have more experience

#

In those conditions, youll either go through tons of iterations or get it right from the start

#

You think you'll get it right from the start and be confident about it?

#

That's one of the reasons why working solo on your own projects can't make you a good engineer

main girder Feb 9, 2025, 10:28 PM

#

interesting

split rampart Feb 9, 2025, 10:29 PM

#

you think it's nonsense?

#

Just I have negative experience related to the load on a personal project vs a project during an internship in a non-personal project

main girder Feb 9, 2025, 10:32 PM

#

you can definitely set yourself difficult goals you dont know how to do and then learn how to do them and not be satisfied until its sufficiently flexible/fast/whatever

split rampart Feb 9, 2025, 10:33 PM

#

Well, maybe you know how to optimize your work process

#

I had to simply rethink the order in which things should be done and where to allocate resources lol

#

because you have 6 big tasks hanging over you, and you need to get them all done, whereas before you were only handling one of these six, and over a longer period of time

#

and then your manager comes and says it's all wrong because of security risks, and this part won't work well in conditions you didn't even consider

#

That's why I don't get how you manage to get everything right on the first try?

#

how do you do things, will?

and how do you spend two days just looking for a name for a print function

} ip_table_entry;```

flint idol Feb 13, 2025, 1:45 AM

ok I did that

#

and also for some unrelated reason also made my HPET, SMP, and IOAPIC code all stop using my ACPI table parsing

#

and switch to uacpi early table access

#

I will make my DHCP thing in linux userspace first

#

and port it to obos when I get sockets

#

ngl doing it in userspace is gonna be BORING

#

and nothing is stopping me from doing it in kernel-space

DHCP is such an annoying protocol

white mulch Feb 13, 2025, 9:22 PM

#

why

#

its pretty simple

flint idol Feb 13, 2025, 9:22 PM

#

I am just not a fan of it

#

just a skill issue on my end

#

I need to decode the DHCP options now

#

in received packets

#

should be "fun"

#

anyway my DHCP client will simply take the first DHCPOFFER and use that

#

idk if I'm supposed to tell everyone else that I rejected their offer

#

I'll check that quickly

white mulch Feb 13, 2025, 9:24 PM

#

flint idol should be "fun"

at least it has a nice format where you can skip ones you don't care about lol (as there is the length field after the tag before any data)

flint idol Feb 13, 2025, 9:24 PM

#

fair

#

wait wha

#

what is the difference between DHCPOFFER and DHCPACK

white mulch Feb 13, 2025, 9:31 PM

#

ack is what the server sends after you accept an offer (using the request packet)

flint idol Feb 13, 2025, 9:32 PM

#

ah

white mulch Feb 13, 2025, 9:32 PM

#

I guess in theory it could also nak your request in some cases

#

like if you request an ip already in use or smth

flint idol Feb 13, 2025, 9:35 PM

#

when I request options using the PARAMETER_REQUEST option, do I do that in DHCPDISCOVER or DHCPREQUEST

#

I mean probably DHCPDISCOVER

white mulch Feb 13, 2025, 9:36 PM

#

yeah

flint idol Feb 13, 2025, 9:37 PM

#

thanks

white mulch Feb 13, 2025, 9:37 PM

#

in request you only need the requested ip you want to accept + the dhcp server

flint idol Feb 13, 2025, 9:38 PM

#

I see

white mulch Feb 13, 2025, 9:38 PM

#

and the siaddr from the offer packet ig but that's part of the header not options

flint idol Feb 13, 2025, 9:39 PM

#

DHCP clarifies the interpretation of the 'siaddr' field as the
address of the server to use in the next step of the client's
bootstrap process. A DHCP server may return its own address in the
'siaddr' field, if the server is prepared to supply the next
bootstrap service (e.g., delivery of an operating system executable
image). A DHCP server always returns its own address in the 'server
identifier' option.

white mulch Feb 13, 2025, 9:39 PM

#

or well idk if that's really required but I do that

#

mabe its not

#

because the same address is also put to the dhcp server option

flint idol Feb 13, 2025, 9:40 PM

#

#

DHCPREQUEST seems to want siaddr set to zero

#

although I will have to say that the DHCP spec putting the message type in an option is annoying

#

I do suppose that the header format is from a different protocol

white mulch Feb 13, 2025, 9:44 PM

#

flint idol DHCPREQUEST seems to want siaddr set to zero

ah good to know, I guess the example in the wikipedia page is wrong in that regard (though ig its just ignored by most servers even if you happen to set it)

upper tulip Feb 13, 2025, 9:49 PM

#

flint idol I do suppose that the header format is from a different protocol

BOOTP

flint idol Feb 13, 2025, 9:49 PM

#

yeah

#

okay I just added a dhcp_foreach_option helper

#

and implemented part of my dhcp_discover function

#

aka the thing that looks for an offer

#

none of this is tested atm

#

but anyway

#

now it can:

format and broadcast a DHCPDISCOVER message, which also requests the routing info, subnet mask, a broadcast address, and whether the server says to enable IPv4 forwarding or not
scan for offers and choose one

#

next thing I need is to implement is accepting the offer

#

after finishing my dhcp_discover function

#

I want to implement dhcp_release and dhcp_inform functions

flint idol Feb 13, 2025, 10:43 PM

#

I might just ignore all offers where siaddr is not the same IP that is in the ipv4 header

#

for simplicity (I don't want to implement ARP again)

short mortar Feb 13, 2025, 11:02 PM

#

flint idol DHCP is such an annoying protocol

It's just 4 broadcast packets

flint idol Feb 13, 2025, 11:11 PM

#

exactly

#

ig the main thing annoying me was the fact I had to use raw sockets

flint idol Feb 14, 2025, 12:23 AM

#

so in theory I have DHCP discovery implemented

#

it's just nothing is tested at all

flint idol Feb 14, 2025, 12:40 AM

also in that case what's sioc supposed to mean lol

flint idol Feb 14, 2025, 2:23 AM

it seems like I need pcap_set_immediate_mode

uncut narwhal Feb 14, 2025, 2:23 AM

flint idol Feb 14, 2025, 3:35 AM

and all of those values are indeed correct

anyway

I will push this code soon

#

I need a better name for this

#

obos_dhcpd isn't pretty

#

odhcpd already exists

#

now, my DHCP client for obos doesn't actually currently work on obos

how I designed it makes it basically fully cross platform as long as you define like 3 functions

deep ember Feb 14, 2025, 3:49 AM

dhcpd makes it sound like it's a dhcp server

flint idol Feb 14, 2025, 3:49 AM

#

good point

#

dhcpclient

#

no that's too long of a name

deep ember Feb 14, 2025, 3:50 AM

#

dhcpcd is called dhcpcd for a reason :^)

flint idol Feb 14, 2025, 3:50 AM

#

okay new name is obos_dhcpcd

#

or actually

#

obos_dhcpc

#

since it isn't a daemon

vale nymph Feb 14, 2025, 3:53 AM

#

its a demon 👿

flint idol Feb 14, 2025, 3:53 AM

#

flint idol how I designed it makes it basically fully cross platform as long as you define ...

you basically just define a function to transmit data on your interface of choice, set interface->mac_address (interface is some struct passed around represting an NIC or smth) to the MAC address of your interface, and have something calling interface->data_ready whenever there is data ready

#

and then it also needs you to define these functions

extern void frame_initialize(frame* f, const void* data, size_t sz);
// Decrements refs, and if it is zero, free data.
extern void frame_unref(frame* f);
extern frame* frame_alloc();
uint32_t dhcp_generate_xid();
__attribute__((format(printf, 1, 2))) int dhcp_log(const char* format, ...);```

vale nymph its a demon 👿

does astral have it's own DHCP client or did you port one or smth

vale nymph Feb 14, 2025, 3:56 AM

#

flint idol does astral have it's own DHCP client or did you port one or smth

I wrote my own crappy dhcp client

flint idol Feb 14, 2025, 3:56 AM

#

cool

#

or maybe not cool

#

I'm too tired to think

vale nymph Feb 14, 2025, 3:57 AM

#

it does its job nicel

#

y

#

(not tested against a real router)

flint idol Feb 14, 2025, 3:57 AM

#

lol

#

mine is tested against a real router on a wifi with many devices on it

#

I wonder how long astral would hold in a "real" network

#

obos starts to melt after ~5 minutes of receiving packets

#

until it dies out

flint idol Feb 14, 2025, 3:59 AM

#

flint idol I wonder how long astral would hold in a "real" network

maybe one day I will write a basic r8169 driver for astral

#

Tenor

#

average DHCP client-server transmission

#

lol

#

best DHCP client

#

I wrote some dumb program

#

that writes out raw bytes onto the network

#

I should use it on /dev/urandom

#

trl

#

what could possibly go wrong

#

now I go slep

#

ah shit

#

okay network is back

flint idol Feb 14, 2025, 11:20 PM

#

anyway

#

time to start

#

writing TCP code

#

rfc793 is a lot simpler than newer specs

#

To govern the flow of data between TCPs, a flow control mechanism is
employed. The receiving TCP reports a "window" to the sending TCP.
This window specifies the number of octets, starting with the
acknowledgment number, that the receiving TCP is currently prepared to
receive.

#

interesting

white mulch Feb 15, 2025, 11:10 AM

#

btw if you want to make lazy irql even faster in vm's you can have a flag that gets set by the irq handler in case it alters cr8, check that inside the irql lower function and only if its set alter cr8 (though it also requires you to disable interrupts for the duration when you do the check + possible cr8 modification)

flint idol Feb 15, 2025, 12:35 PM

#

I want to make a big change to OBOS
And that is changing the allocator interface

#

currently it's doodoo because it uses function pointers, which makes it so nothing can be inlined, and also compiler warnings related to use after frees and stuff like that won't work

flint idol Feb 15, 2025, 4:41 PM

#

I just fixed a bug with the r8169 driver

#

where it was basically always one packet behind for some dumb reason

#

while receiving stuff

if you want to test it over the internet, you can try to talk to a MOTD server

#

was it message of the day or quote of the day

#

I forgot

#

but yeah

flint idol Feb 15, 2025, 5:51 PM

#

https://en.wikipedia.org/wiki/QOTD

QOTD

The Quote of the Day (QOTD) service is a member of the Internet protocol suite, defined in 1983 in RFC 865 by Jon Postel. As indicated there, the QOTD concept predated the specification, when QOTD was used by mainframe sysadmins to broadcast a daily quote on request by a user. It was then formally codified both for prior purposes as well as for ...

#

QOTD it seems

vale nymph Feb 15, 2025, 5:51 PM

#

I remember there being a public one

flint idol Feb 15, 2025, 5:52 PM

#

anyway I already have tested it over my home network

vale nymph Feb 15, 2025, 5:56 PM

#

I think djxmmx.net is the one that still works

#

send an udp packet and it'll reply with qotd

flint idol Feb 15, 2025, 5:56 PM

#

got nothing

vale nymph Feb 15, 2025, 5:56 PM

#

hmm

flint idol Feb 15, 2025, 5:56 PM

#

wait it's tcp

#

and not udp

#

vale nymph Feb 15, 2025, 5:57 PM

#

no it also works over udp

#

tho idk if the guy is exposing it over udp anymore

flint idol Feb 15, 2025, 5:57 PM

#

flint idol wait it's tcp

as in, the site is only serving it on TCP

vale nymph Feb 15, 2025, 5:57 PM

#

I remember there was an udp one

#

blegh

#

#1061407633745125397 message

#

I had done it with just udp

flint idol Feb 15, 2025, 6:02 PM

#

I will just do nmap 0.0.0.0/0 -p17

let me ssh as root into your computer pweading

flint idol Feb 15, 2025, 6:38 PM

#

fine

#

my ip is 127.0.0.1

#

root password is password123

flint idol Feb 15, 2025, 7:05 PM

#

#

woaw why does obos spend so much time in IO instructions

#

oh wait

#

port e9

#

output

#

but my question is why an I rdmsring so much

#

seemingly

#

oh

flint idol Feb 15, 2025, 9:59 PM

#

        frame->buf = map_registers(Mm_AllocatePhysicalPages(((TX_PACKET_SIZE*128) + (OBOS_PAGE_SIZE-((TX_PACKET_SIZE*128)%OBOS_PAGE_SIZE))) / OBOS_PAGE_SIZE, 1, nullptr), ((TX_PACKET_SIZE*128) + (OBOS_PAGE_SIZE-((TX_PACKET_SIZE*128)%OBOS_PAGE_SIZE))), false, true);```
just found this line of code in obos lol

#

in case you are wondering what it does, I think it allocates contiguous space for a buffer then maps it

weak kestrel Feb 15, 2025, 10:00 PM

#

code from obos
I think ...

flint idol Feb 15, 2025, 10:01 PM

#

yeah I kind of can't decode my own code that I wrote barely a month ago

cedar geyser Feb 15, 2025, 10:02 PM

#

weak kestrel >code from obos >*I think* ...

Well look at it

flint idol Feb 15, 2025, 10:05 PM

#

anyway I shall continue

#

work on TCP

#

I think implementing reception first will be easier

#

because then when I start doing transmission I can have a way of checking for ACKs from the other side

#

I will give 0.00$ to whoever implements a virtio net driver for obos

white mulch Feb 15, 2025, 10:09 PM

#

imo virtio in general is weird, like its somehow more complex than real hardware which is why I never really got around to making drivers for it

#

though it might also be caused by the fact that the virtio spec sucks lol

flint idol Feb 15, 2025, 10:10 PM

#

I have heard it is easier

#

than some real devices

#

and I will also give 0.00$ to whoever implements a e1000 driver for obos

#

testing on real hardware exclusively kind of really sucks

white mulch Feb 15, 2025, 10:12 PM

#

did you implement rtl8139 yet

flint idol Feb 15, 2025, 10:12 PM

#

no

#

I have heard it is like the r8169 but simpler

white mulch Feb 15, 2025, 10:13 PM

#

you can basically use the same driver for it

#

with a few if's

flint idol Feb 15, 2025, 10:13 PM

#

I will look into that soon

#

because debugging on real hw sucks!

#

I am thinking to implement gdbstub over UDP in obos

#

I already have the gdb stub

#

I just need to put in the necessary "glue" code

timid elk Feb 15, 2025, 10:15 PM

#

sounds cool

#

gdbstub over ARP

flint idol Feb 15, 2025, 10:15 PM

#

flint idol I already have the gdb stub

I do suppose that I will need to make some changes, I broke that code back in August or September

timid elk Feb 15, 2025, 10:15 PM

#

because OBOS is ARP OS

flint idol Feb 15, 2025, 10:15 PM

#

timid elk gdbstub over ARP

lol

real pecan Feb 15, 2025, 10:15 PM

#

Implement a new TCP like protocol for obos

timid elk Feb 15, 2025, 10:15 PM

#

gdb stub over quic

#

gdbstub over carrier pidgeons

#

pigeons

#

pidgins

#

hpw is it spelled

flint idol Feb 15, 2025, 10:16 PM

pigeons

timid elk Feb 15, 2025, 10:17 PM

#

yea

flint idol Feb 15, 2025, 10:17 PM

#

flint idol I just need to put in the necessary "glue" code

actually I want to do that now

#

because I found a bug with UDP that only happens in some cases

flint idol Feb 15, 2025, 10:18 PM

#

flint idol because I found a bug with UDP that only happens in some cases

this bug doesn't affect UDP in 'server' mode

#

but anyway I will give the details of the bug

#

in a bit
