ip mptcp monitor reports: [SF_CLOSED] error=111 #338

please additionally report even the command used to run the server and the client. |
|
Please find the command used to run the server and client: strace -o strace.serve -f ip netns exec ns2 iperf3 -s -B 0.0.0.0 > /dev/null & strace -o strace.client -f ip netns exec ns1 iperf3 -c 10.1.1.2 -t 1 > /dev/null & |
The above endpoint configuration is wrong (beyond the typo): ns1 is the 'client' namespace, a signal endpoint will work only in presence of a port (and will be quite an unusual setup)
The above endpoints configuration is wrong: ns2 is the server namespace, the 'subflow' flags means the server will try to connect back to the client address/port (and will find a closed port)
it would be better/simpler to add all the endpoint flags with a single command, at least for valid endpoint [...]
This is the server connecting back to the client, receiving a ECONNREFUSED error, as expected
[...] it looks like there has been some packet drop, as the pcap traces does not contain the TCP reset causing the ECONNREFUSED above. |

Thanks, @pabeni |

Currently amdgpu calls drm_sched_fini() from the fence driver sw fini routine - such function is expected to be called only after the respective init function - drm_sched_init() - was executed successfully. Happens that we faced a driver probe failure in the Steam Deck recently, and the function drm_sched_fini() was called even without its counter-part had been previously called, causing the following oops: amdgpu: probe of 0000:04:00.0 failed with error -110 BUG: kernel NULL pointer dereference, address: 0000000000000090 PGD 0 P4D 0 Oops: 0002 [#1] PREEMPT SMP NOPTI CPU: 0 PID: 609 Comm: systemd-udevd Not tainted 6.2.0-rc3-gpiccoli #338 Hardware name: Valve Jupiter/Jupiter, BIOS F7A0113 11/04/2022 RIP: 0010:drm_sched_fini+0x84/0xa0 [gpu_sched] [...] Call Trace: <TASK> amdgpu_fence_driver_sw_fini+0xc8/0xd0 [amdgpu] amdgpu_device_fini_sw+0x2b/0x3b0 [amdgpu] amdgpu_driver_release_kms+0x16/0x30 [amdgpu] devm_drm_dev_init_release+0x49/0x70 [...] To prevent that, check if the drm_sched was properly initialized for a given ring before calling its fini counter-part. Notice ideally we'd use sched.ready for that; such field is set as the latest thing on drm_sched_init(). But amdgpu seems to "override" the meaning of such field - in the above oops for example, it was a GFX ring causing the crash, and the sched.ready field was set to true in the ring init routine, regardless of the state of the DRM scheduler. Hence, we ended-up using sched.ops as per Christian's suggestion [0], and also removed the no_scheduler check [1].

Hi @dmytroshytyi-6WIND, could you show the final tesbed setup that you use to simulate the virtual enviroment in order to verify the correct behaviour of MPTCP? Thanks in advance!!! |
|
@AlejandraOliver if you are interested in having a development environment for MPTCP, you can have a look at this: https://github.com/multipath-tcp/mptcp-upstream-virtme-docker |
|
I want to set up a real enviroment with two machines but not a virtual enviroment like it show in https://github.com/multipath-tcp/mptcp-upstream-virtme-docker |
|
@AlejandraOliver, The next might help for creating a real environment with two machines:
You might find many examples on the internet. |
|
I don't see any example of what commands I need to use to create the enviroment on the internet, or any example of a created scenario but thanks anyway, I will see. |

Enable the cpu v4 tests for LoongArch. Currently, we don't have BPF trampoline in LoongArch JIT, so the fentry test `test_ptr_struct_arg` still failed, will followup.

Hello,
I'im curious what I'm missing in this setup, such that I observe an interesting behavior of sublflow [SF_CLOSED] error=111
I'm runing the next kernel:
IPERF is using IPPROTO_MPTCP.
Testbed setup:
here is a result of:
tcpdump packet trace:
Thanks!
