Use RPS or RFS https://www.kernel.org/doc/html/latest/networking/scaling.html?highlight=rps

Okey, so in that case, how do you deal with it?

this is not related to accel, because accel-ppp is only control-plane for pppoe sessions so slow performance of pppoe is related to kernel, not to accel-ppp

Only difference is type of accel session. ipoe vs pppoe. So this is not related to accel?

This question is not related to accel, traffic forwarding is done by kernel, not by accel-ppp so please contact netdev (https://lore.kernel.org/netdev/ ) if you want to discuss it

Hi @Dimka88, I have implemented this feature for personal needs, but I would like to contribute with the code if possible. Please let me know how can I upload the changes so you can review. Should I do this on Github?

Summarize:
Issue appears with veth and vlan_mon only on 4.19. If use bridge instead, all will work properly. As Deb10 support expired around 1 year we make decision to delete tests on Deb10 from github test

I can confirm that kernel 5.10.0-0.deb10.24-amd64 is fixing issue on Debian 10.

It is not fixed in actual version. It is required to fix here: https://github.com/accel-ppp/accel-ppp/blob/2b865db72bc2ddc6411950d72f1c23e8ef115b8a/accel-pppd/ppp/ipcp_opt_ipaddr.c#L100 , https://github.com/accel-ppp/accel-ppp/blob/2b865db72bc2ddc6411950d72f1c23e8ef115b8a/accel-pppd/ppp/ipv6cp_opt_intfid.c#L209 , https://github.com/accel-ppp/accel-ppp/blob/2b865db72bc2ddc6411950d72f1c23e8ef115b8a/accel-pppd/ctrl/ipoe/ipoe.c#L668

Attached the patch i made for the version 1.12.0-202-g28fe4de. It will use Calling Number/Called Number as RADIUS Calling-Station-Id/Called-Station-Id in case they are present in L2TP ICRQ, otherwise old beahvior is used (LAC/LNS IP addresses).

UPD:// CMake Error looks pretty strange. It get info by the command git describe --tags --always
From your repo it return 6e5f998 because you clone only single branch.

root@debian11:/opt/accel-ppp/build# git describe --tags --always
6e5f998

So, maybe we have to improve generate version functionality also

Hi @v.huti , I see some cmake Errors

Hi @Dimka88! The warnings are fixed in the following pull request:
https://github.com/accel-ppp/accel-ppp/pull/64
From my understanding, the situation is next:

In general, assuming anything about data alignment is a bad practice that leads to very obscure errors. 
Taking the address of a packed member is dangerous since the reduced alignment of the pointee is lost.
If the pointer value is dereferenced, this can lead to memory alignment faults in some architectures.

I think it is not implemented yet, but is is good feature request

just to discuss the possibilities.
I see Calling-Number/Called-Numer AVPs can be taken from attr->val.octets doing something within l2tp_recv_ICRQ procedure:

This cmake gives working deb on VyOS on Debian11 machine:

make
cpack -G DEB

i have testsed last version accel. its ok

Hi.
Is there any recommendations on compiling and embedding newly compiled version of accel-ppp to vyos 1.4 ?
I mean how to install newly built package into VyOS 1.4.
The deb built on Debian11 and installed with dpkg on VyOS does not start for some reason with no output.

Hi
Any one for help to make this ?

Hi Dimka88!

also, we have to check driver performance when ipoe_lookup_hwaddr is used for many sessions (many sessions in vrf)

It will not work if there in the conditions below:

1. two sessions in L2 ipoe shared mode
2. the same interface (e.g. eth0)
3. first session without vrf
4. second session with vrf
5. the same ip.src for both sessions

additional information and patches how it should works

But for Service name i need your help to extract from PADI or PADO

i will try to make patch for this.
many of use case send to radius clear mac for user and mac for machine and not need to send interface
this with interface and service will use only fkr cli interface to show local in system .

I use this one: show sessions match calling-sid vlan123

calling-sid/called-sid send to radius as info for user
separate column need only for statistic local in cli when statistic or only to see user per interface

why do you want to have "uplink interface" as a separate column? why calling-sid/called-sid with interface name is not enough?

Hi @svlobanov
Yes this list interface here :

@micron
regarding to interface:

ifname-in-sid=called-sid|calling-sid|both:

Hi
yes check in man/doc but calling-sid or called-sid not get interface .

You can include "uplinkif" to calling-sid or called-sid, it is already implemented. Please check man/doc related to this feature

Thank you @svlobanov .

PR https://github.com/accel-ppp/accel-ppp/pull/32

Unfortunately, I can not reproduce this issue, please reopen this ticket when this issue will appear again.

no in this case work with latest master and after this segfault not see this problem.
may be is network problem send wrong package

Hi @micron , did you modify the accel-ppp code by yourself, exactly functions related to Service-Name?

Hi @slima , do you have a chance to test on the fresh accel-ppp version from the master branch?

please check this patch https://github.com/accel-ppp/accel-ppp/pull/31
