Logged on 2021-08-01 12:21:40 asciilifeform: cgra: seems to me that the correct pill would be a per-peer memory odometer.

18:53

still, separately need fixing the issues of 1) unbounded agent string, and 2) std::vector internal capacity not automatically reducing -- because you wouldn't want 125 simultaneous peers to consume >2GB of RAM

18:53

and what's more, std::string afaik has same capacity mechanism, which i intend to eventually review as well

18:54

cgra: imho the Right Thing is a 'peer may use this-many kB and if more, disconnect+permaban'

18:54

rather than prb-style gnarly types with custom alloc logic

18:55

125 peers oughta be able to use 125MB at a time. 1 each. and not more.

18:56

( 1 decimal MB, i.e. 1e6byte. given that this is the largest permissible mass of data in trb. )

Logged on 2021-08-01 14:50:45 asciilifeform: rather than prb-style gnarly types with custom alloc logic

18:59

cgra: correct. adding specialcases will only make the thing weigh more and even less (if can imagine this) fits-in-head than the existing horror.

19:00

the 'cleanest' approach is the one which adds the least moving parts (or preferebly ~removes~ existing)

19:00

... while closing the hole

19:00

yeah, i'm thinking of an acceptable solution that replaces parts with smaller ones

19:01

right

~ 23 minutes ~

19:24

one more trb observation: if there's an easy way to make a tx upwards from 55kB in weight, that trb will accept, the wedging issue is still present, because no odometry for tx data, and the attacker could easily request 49990 times the same tx, in one 'getdata'

19:25

for extra impact and pedantry, could request ~1MB blocks for the rest of the 50000 allowed inv's

19:27

cgra: indeed no one's fixed the tx odometer yet. as for the latter, that oughta trigger the blox odometer, neh

19:27

asciilifeform: yeah, but 10 blocks prolly under the 10MB mark

19:28

(the default red area in sendbuffer odometer)

19:31

cgra: the common theme here is that a peer ought not to be able to eat arbitrary ram. and that the correct end of the funnel to plug, is to actually measure the consumption, and kickban mercilessly. rather than trying to find each and every one of 'over 9000' places where shitoshi&co defined a type that can stretch to infinity

19:33

asciilifeform brb

19:46

asciilifeform: the analogy lingering in my mind is 'still could be worth looking for the bottom-most funnel, and finding the only pointy end to plug', but i keep your words in mind. also i currently have difficulty in understanding how to reliably measure -- copper wiring each and every spaghetto?

19:47

measure as in 'just measure, otherwise let the pile keep stinking'

19:57

whaack: ty!

20:01

whaack: btw, does segwit-bomb tx make it any easier to bake large (byte-wise) transactions? i so far didn't look into your experiments in detail (or whole segwit), so would't know

20:03

(maybe too early to ask, i haven't looked carefully enough yet, how to even bake such cakes traditionally)

20:04

cgra: yes it does make it slightly easier because you don't need to provide signatures and thus don't have to do as much computation

20:04

just that maybe using plenty of 1-sat outputs works

20:05

whaack: is it that you don't even need an address you control?

20:05

can play with the bait money only

20:05

cgra: yes, that's true as well

20:05

ok

20:06

normally you would need atleast an address with 1 satoshi to get a valid txn, and atleast a fee's worth of satoshi's to get it accepted to trb's memerypool

20:06

*

whaack doesn't actually know if trb has a min txn fee for accepting to the memory pool

20:07

whaack: it has two, 1000 sats and 10000 sats

20:07

if you cross the latter tier, no questions asked
