test/robot should be updated as the value of net.ipv4.ping_group_range is changing to 0 https://build.suse.de/request/show/257506

btw, don't know who is maintaining robot package, but maybe it should/could be part of update when kernel parameters are changed

I'm just testing aaa_base where this bug https://bugzilla.suse.com/show_bug.cgi?id=1174504 explains this failure.

If I understood this correctly, this change is needed to adjust the behaviour of ping.

Here is the related commit to aaa_base: https://github.com/openSUSE/aaa_base/pull/77/files

We need to block the update until we establish what parameters have been changed. These parameters would directly affect SAP customer workloads.

Which RobotFW test is failing and what is its value and what value is expected?
A bug should be filed and the update rejected or in this case retracted.

Cheers
James

https://openqa.suse.de/tests/overview?distri=sle&version=15&build=%3A21647%3Aaaa_base&groupid=159

Looks as if the update aaa_base (21647) has caused this change. If this is indeed the case, then please reject the update stating that ipv4 ping return value has changed and should be reverted.

It appear that the same test is failing for:

15-sp3
15-SP2
15-SP1
15-ga

This bug explains why the change was done:
https://bugzilla.suse.com/show_bug.cgi?id=1174504

The reasoning behind the change was adjusting the behavior of ping.

The MR to address this, if it gets approved:

# failure: 

expected: 0
returned: 2
invalid value: '2', expected '0'

15-SP1 did always fail since Nov 03:

# Test messages # Sysctl_net_ipv4_udp_mem
# failure: 

expected: 41000:47000 54000:62000 80000:91000

15-SP2 failing since Nov 24:

# Test messages # Sysctl_kernel_unprivileged_bpf_disabled
# failure: 

expected: 0
returned: 2
invalid value: '2', expected '0'

15-SP3 failing since today Nov 25:

# Test messages # Sysctl_kernel_unprivileged_bpf_disabled
# failure: 

expected: 0
returned: 2
invalid value: '2', expected '0'

Thanks Michael for bringing this to our attention.

This is excellent that the SAP sys-param-checks are doing their job and detecting important changes to the default settings and none of these changes should go under the radar.

We now need to determine which updates have caused these changes and why.

It's not clear to me which update has caused the 12-SP3 failure, but I'm sure that something was missed here in the Single Incidents.

As for the issue since 4th Nov, we must have missed this, since it was hiding behind the other issue Sysctl_net_ipv4_ping_group_range.

The Sysctl_kernel_unprivileged_bpf_disabled is a change in the kernel (e.g. incident 21969)

I forgot to mention: a planned change: https://jira.suse.com/browse/SLE-22575

There are two new failures which are not related to previous failure net.ipv4.ping_group_range caused by aaa_base, see https://suse.slack.com/archives/C02D16TCP99/p1638355107168400
