[Bug 1873447] Re: [bionic][autopkgtest] ipset failing autopkgtest after kmod sru

2020-04-22 Thread Rafael David Tinoco
Adding block-proposed-bionic so this fix can be added if there is any
SRU to ipset package.

Proposed forcing bad test here:

[Bug 1873447] Re: [bionic][autopkgtest] ipset failing autopkgtest after kmod sru

2020-04-22 Thread Rafael David Tinoco
Since this was supposed to be a SRU, but it is only a autopkgtest fix:

- patch: 2a66a0df03788d8a7e95972847545de0ade0dd8e fixes the issue

- the patch only touches the autopkgtests (not suitable for SRU)

- last time test ran was at the end of 2018 and it worked

- after that, kernel has included the following commit:

v4.19-4705-g886503f34d63 : netfilter: ipset: actually allow allowable
CIDR 0 in hash:net,port,net

and the test started failing.

- forcing bad test is the best to be done and this will unblock the kmod
fix:

2020-04-22 Thread Rafael David Tinoco
Was able to reproduce:

hash:net6,port,net6: Range: Create a set: passed
hash:net6,port,net6: Range: Add zero valued element: FAILED
Failed test: /sbin/ipset 2>.foo.err -A test 2:0:0::1/24,0,0:0:0::0/0

autopkgtest [18:08:23]: test regression:  - - - - - - - - - - results - - - - - 
- - - - -
regression   FAIL non-zero exit status 1

and to fix it:

hash:net6,port,net6: Range: Create a set: passed
hash:net6,port,net6: Range: Add zero valued element: passed
hash:net6,port,net6: Range: Test zero valued element: passed
hash:net6,port,net6: Range: Delete zero valued element: passed

by cherry-picking the upstream fix:

commit 2a66a0df03788d8a7e95972847545de0ade0dd8e

Correct to test null valued entry in hash:net6,port,net6 test

[Bug 1868882] Re: [SRU] Put ipmctl into Bionic (and update necessary deps)

2020-04-22 Thread Andreas Hasenack
MIR stands for *Main* Inclusion Request. It's different from processing
a NEW package. Or else we would only accept NEW packages in Ubuntu if
they went into main.

Just a note that Jeff wasn't asking for an MIR, but an SRU.

All stack traces seem to come from "fsnotify" subsystem and waiting on
delayed work (completion) for fsnotify marks destruction after a
inotify_release() was called. Completion did not happen for the past 2
minutes. Without a kernel dump it is hard to tell if completion was
still ok - due to kthread being overloaded doing scheduled work and/or
the marks group destruction - or there was a dead lock for the
completion due to a kernel bug.

If this is reproducible, I think that having a kernel dump would help
identifying the issue. I'm letting the kernel team to handle this and
marking all other issues as dealt per previous comments.

[Bug 1780341] Re: squid should default to more human friendly timestamps

2020-04-22 Thread Andreas Hasenack
For reference, just because it took me a while to get the syntax right,
plus https://bugs.squid-cache.org/show_bug.cgi?id=4905 made me scratch
my head a bit wondering why it wasn't working when I used "squid"
instead of another name:

[Bug 1868882] Re: [SRU] Put ipmctl into Bionic (and update necessary deps)

2020-04-22 Thread Rafael David Tinoco
Hello Jeff,

I have opened a card to keep track of this work in 20.10. I'm not sure
that a MIR will be possible (for ndctl/ipmctl) based on previous denial
but we can take a look later after we MERGE latest upstream release
(02.00.00.3759) to 20.10.

For now I'm closing this bug as there is nothing to be done here until
20.10. I will include you in the 20.10 ndctl/ipmctl merge public bugs
for your awareness.

Thank you

Rafael
