binutils, flex must be removed from makedepends as they are part of base-devel.

Thank you for maintaining this package!

Looks like I'd forgotten to add 0001-Build-with-Archlinux.patch into the PKGBUILD although included in the encompassing patch. It doesn't build from AUR as a result.

UPDATE: this commit has broken the original patch. Here is a new patch to account for changes to Makefile: 0001-Build-with-Archlinux-1.patch

Fun!

@selfdenial: thank you so very much! Things should be fine again now, thanks to your efforts :)

(sorry for taking so long to get things sorted)

Edit: patches never seems to work well with markdown (patches successfully but makepkg fails). Here is a working link: 0001-Restore-build-with-later-revisions.patch

Hi I'm no expert but I've managed to make this build and might as well share what I've changed:

Also getting the file.patch error.

Note that new compilation instructions were pushed a few days ago.

I've been succesfully building "opensnitch-ebpf-module-git" for many months - until recently

This error seems to have been introduced recently by some source change

PKGBUILD needs to be updated due to this commit from last week: https://github.com/evilsocket/opensnitch/commit/210e843aabd82986f38914e25dbaa6ffb9bfc8b9

The building process now needs to include the newly added file common_defs.h

Last few lines when building the package:

         ^~~~~~~~~~~~~~~

Even though the package building completes just fine without common_defs.h, eBPF as monitor method stopped working for me completely. I ran into following error when trying to set eBPF in the Opensnitch settings

error starting ebpf monitor method: eBPF module opensnitch.o malformed, bpfmap[tcp6] nil when trying to use eBPF

nns commented on 2022-11-22 05:21 (UTC)

As per the new eBPF instructions, the location /etc/opensnitchd/ for the compiled program is deprecated, and the locations /usr/local/lib/opensnitchd/ebpf/ and /usr/lib/opensnitchd/ebpf/ are preferred instead.

https://github.com/evilsocket/opensnitch/commit/71747ebed52a586d41b4fd78360edfc46e361967

ebpf instructions were updated

weru345 commented on 2022-08-14 06:43 (UTC)

Due to linux 5.19.1.arch2-1 hitting Core repo a few hours ago, the PKGBUILD needs to be updated.

(More of a PSA for all the early birds wondering why their VPN to a Wireguard server stoppped working after updating to the latest kernel version. This actually took me a good hour to figure out...)
