I'm getting "Bad file descriptor" when trying to run any of the scripts. Here's the error log from the tcplife: http://ix.io/193v

@edh I was hoping to actually trace some programs using BPF with this toolset, that's why I am curious about this one in particular. But maybe there are some other similar tools there that do work. I'll try and do some research, thanks a lot for looking into this!

@enchantner Sorry, I can't reproduce your problem using linux 4.15.3-1, linux-hardened 4.15.10a-1 and linux-hardened 4.15.12a-1.

EDIT: I took a look at the ticket and ran the trace tool as described by you and it fails as well. The error message was the same. Hence some tools in specific are not working while others do.

Doesn't work for me on latest kernel (4.15.13-1): https://github.com/iovisor/bcc/issues/1634 . Fails to attach kprobes, even though all necessary kernel parameters are present. Is anyone experiencing the same?

Hi,

Just tested 0.5.0-3: Works fine, thanks!

Thanks for all the feedback! I was testing some stuff out but @cippaciong already provided the right answer before I could. Luckily the patch is contained within a single commit (c0d1694e28) and can be easily backported. Can you give the latest version of this package a try. Compilation using clang/llvm version 6.0.0 is working fine on my machine.

@cippaciong: Building the most recent Version (76bec4d5e94f56b42b6417f27b06f95773c8e283) of bcc from git works fine: https://pastebin.com/n04BFrcW

@furcifer_oustale: https://github.com/iovisor/bcc/issues/1513 It's probably related to the recent upgrade of llvm to version 6.0 on arch. Can you try to build bcc cloning from git?

Hi,

The build seems to be broken: When trying to upgrade to 0.5.0-2 i get

The error message is pretty descriptive, but unfortunately i am not a C++ programmer

Edit: Moved error message to pastebin

@cmsigler Thanks!

The checksum was still the one of the original file which was previously shipped with the PKGBUILD and I forgot to update it to reflect the new source of the patch.

I think it is wrong and too cumbersome to rename man pages which clash with other packages. Considering that I introduced the change in the PKGBUILD and upstream explicitly installs them elsewhere I will in this case simply stick to how it was intended to be installed hence I will stop moving man pages around.
