## :closed_book: Discussions

AM: worked on updating procfs to the latest release on Unikraft
CV: provided build static pie for jvm, it still crashes, but its on drive and feedback is welcomed
CV: created draft PR, test SK loader, crashes pretty fast, but the strace runs for a bit, but it has issues with some unimplemented syscalls
CV: looking into mutex

PO: finishing porting osv apps, around 70-80%
PO: switch his student to porting linix-tests in order to test the syscalls, should also periodically join the meet

SJ: musl update, talked to Edi, mostly works for x86, for ARM today we expect a PR, should be done for the release

SK: worked on netlink abstraction for the libc calls, needed for some applications, implemented only the basics in order to start it going

SK: asked PO about the if the socket calls address is recorded
PO: needs to check, probably not
SK: it is tricky to save it but it would important to have it for netlink
SK,PO: further discussion about netlink and how to obtain the above mentioned data

TT: managed to run the new elf-loader, wrote some details about the apps, has issues with debugging
TT: no output on the go app, they seem to not run

CV, SK: reiteration about the static PIE for JVM
CV: looking into futex for missing calls

SK: how big is the image used by CV
CV: didn't particularily check for it, no access

FH, SK: please specify in the chat the size
SK:check size also look into futex, can give access to CV in order to build it himself

## :wrench: TODOs and Decisions

SK: Give CV acces to the repo in order to study more about futex

CV: post the size of the the rootfs of the openJDK

SK: try to release th elfloader, strace and the initial netlink implementation and posix-procfs extension as part of the upcoming release (this is part of the app compat release)
