updated inner_call for hashing fn to follow generic approach #33128

sanjsingh07 · 2023-09-02T10:51:33Z

Problem
inner_call() function for hashing syscalls (sha256, keccak and blake3) are nearly identical

Summary of Changes
de-replicated the hashing syscalls to follow generic and trait approach, ref #33046.

LGTM

now we're headed in the right direction! thanks for the changes

so I went with the default values of sha256 in compute_budget variables for the other hashes as well since I didn't know which values they are supposed to use as previously they were using the same ones as sha256 so if they need to be updated lmk.

hrm... wouldn't have expected that. we should definitely properly measure them, but that's out of scope fore this change set. i'd expect at leaset blake3 to be cheaper than sha256

ok. looks good to me know. let's see what the robot says!

just realized you may not be able to view the ci output... looks like it's not liking trailing whitespace at programs/bpf_loader/src/syscalls/mod.rs:232. if you want to iterate faster, get ./ci/test-sanity.sh and ./ci/test-checks.sh passing locally. those are typically the bulk of the issues with refactors like this and pretty easy to run locally.

Hey, I was able to see the ci output, and I ran cargo fmt -all to deal with the white space issue, cargo clippy to look for unused and reference related issue, which I've fixed/updated in new commits and also ./ci/test-sanity.sh ran completely fine but ./ci/test-checks.sh failed with below code snippet, and I tried I updating the hack sub-cmd with check which led to different error so you also might wanna check that out

+ exec cargo +nightly-2023-08-25 hack --version --verbose
error: no such command: `hack`

        Did you mean `check`?

ah you need to cargo install cargo-hack, i believe

@sanjsingh07 you don't need to worry about the "this branch is outdated..." warning, so long as it doesn't escalate to "this branch conflicts...". rebasing clears ci, so we'll need to rerun to merge

@Lichtso @alessandrod can i get one of you to sign off on this again? it's ready to merge otherwise

sanjsingh07 · 2023-09-15T15:02:25Z

Oh ok, Thanks for letting me know about that cuz I wasn't sure if it was mergeable with the branch being outdated.

no worries, github doesn't exactly make it obvious!

once we get another sign-off from the runtime team, this will be ready to go

t-nelson · 2023-10-10T20:24:44Z

@Lichtso @alessandrod @dmakarov can we get a final signoff from runtime on this? should be net better than the last time it was approved 😉

t-nelson · 2023-10-12T19:48:14Z

@sanjsingh07 looks like we picked up some trailing whitespace somewhere. ci sanity tests are failing

sanjsingh07 · 2023-10-12T20:03:17Z

@sanjsingh07 looks like we picked up some trailing whitespace somewhere. ci sanity tests are failing

yeah my bad, I might have left that while resolving the branch conflict, so do you want me to push the updated code or you can take care of it while merging?

alessandrod

lgtm! Please remove the whitespace at line 1951 then it's good to go

…et compute budget values

done!

we're r+ ci here. merge when green
