Hello All, Just came across this old message on accessing parameters and arguments for C++

Hello iovisor friends, I found that there seems to be a problem in the eBPF sample source code of the Linux kernel samples/bpf/sockex3_user.c. This program contains the following code:

That's great news! I will play around with these iterators. Thank you!

yes. That's what bpf iterator of task->vma is for. The prog doesn't need to execute "within process B" to read its memory. I think that is exactly what you need. The iterator can read mm of another

Hi Alexei, I'm playing around with using BPF to read a given process' memory for debugging purposes. I'd like to recreate some of the experience that a debugger gives you by stopping and ptrace-ing

Could you describe what prog is going to do? Have you considered using a task iterator parametrized with a particular task?

Hello iovisor friends, I'm curious what my options are for running a BPF program once, immediately, in the virtual memory context of a particular (user space) process. For example, say I want to read

Hi, thank you for the reply. I'll change the code to use RAW_TRACEPOINT_PROBE macro used in other bcc tools. While testing on some old environments which doesn't support raw tracepoints, I noticed

Hi, I was using nfsslower in bcc tools and noticed that it doesn't print out slow commit operations, which sometimes cause long delays in NFS writes. I tried adding code to trace slow commit

Hi Kevin, I see you've made a Github issue as well (https://github.com/iovisor/bcc/issues/4256). That's good, as I would've recommended making one since the mailing list isn't frequently used these

I have some questions about cachetop.py tool. Why the total accesses is defined as the times of entering mark_page_accessed plus mark_buffer_dirty functions? Doesn't enter mark_buffer_dirty must also

Hello, as part of a university project I am analysing the dbslower tool to evaluate the performance cost of tracing the queries and to test what can be traced with it. As MySQL dropped support for

Hi all, We are parsing DHCP packets in TC egress program, In our case, the packet after the UDP header was not present in between skb->data and skb->data_end. On further investigation we found that

Hi, Jules, Just go to https://github.com/iovisor/bcc/issues and you can find quite some issues for you to investigate. Thanks! Yonghong

Hi I am looking for some bcc issues for newbie. Any link ? Jules ..
