from DpkgTerminalLog.txt:

Preparing to unpack .../00-mariadb-server-10.6_1%3a10.6.7-2ubuntu1_amd64.deb ...
/var/lib/mysql: found previous version 8.0

This is mariadb refusing to install over MySQL-8.0. It can't auto-
upgrade from MySQL-8.0 so it gracefully fails rather than destroying
your data.

Could it be  -flto/-ffat-lto-objects related (like
https://jira.mariadb.org/browse/MDEV-25633)? The top part of the stack
trace looks the same.

[Bug 1969160] Re: mariadb [ERROR] mysqld got signal 6

[Daniel Black]

See https://bugs.launchpad.net/ubuntu/+source/mariadb-10.6/+bug/1970634
as its the same problem.

While my 10.6.8-MariaDB-1:10.6 test above what built in an ubuntu-22.04
container, it quite possibly used different compile options than what
produces the packages. As the regions of code of the assertions haven't
changed from 10.6.7, 10.6.8 is unlikely to be a magic fix.

For the moment setting innodb_use_native_aio=0 will avoid the problem

[Daniel Black]

Note the runtime detection in innodb_use_native_aio_default affects the
default value only. Users can explicity set this and really on distros
to provide patched kernels.

Actually create_linux_aio (tpool/aio_liburing.cc:194) should already
catch this exception. So compiler error?

[Bug 1970634] Re: FTBFS: mariadb fails to start due to low MEMLOCK limit

[Daniel Black]

From 5.12 kernel memory locked pages aren't needed -
https://github.com/axboe/liburing/issues/246#issuecomment-816965961.

In #1969160 I tested the upcoming 10.6 release (probably next week
sometime) for crashes in uring initialization failures and it didn't.
Apart from some error log differences from ENOMEM, ENOSYS etc are
handles the same way in the fallback.

I haven't quite concluded how the 10.6.7 release is crashing at the
moment.

With https://bugs.launchpad.net/ubuntu/+source/linux-
hwe-5.13/+bug/195 I assume the jammy kernel 5.15.0 has the right
patches to make 5.15.0 safe despite the MariaDB code not distinguishing
it as so (suggestions of improving kernel version detection welcome).

Checked a rebased https://github.com/MariaDB/server/pull/2036
(openssl-3.0 backport on 10.6 latest from yesterday) in ubuntu-22.04
container and it doesn't assert. The ENOMEM error handling path is the
same as ENOSYS. I will get to the 'uprading' typo though probably not
before the next release sometime in the next week:

[Bug 1913676] Re: libmariadb3 fails to include caching_sha2_password.so

[Daniel Black]

This is a critical bug. More so on Ubuntu because of it installing MySQL
by default. It affects all default connections to the MySQL with MariaDB
connector/C and its dependent library, and every application that
depends on this libmariadb3.

I thought the merge 5 months ago into buster would of made it to the 2
months ago 10.2.29 release.  Odd, but so was the 10.5 only #962597 fix.

If you don't want to package 10.3.30 because it only includes bug fixes
and not security fixes, ok, but package increment on
libmariadb3-1:10.3.29 to resolve this please.

[Bug 1913676] [NEW] libmariadb3 fails to include caching_sha2_password.so

[Daniel Black]

Public bug reported:

The lack of this shared library means MySQL/MariaDB client connectors
connecting to a MySQL-8.0 server (which defaults to
caching_sha2_password being the default authentication for users, will
get a connection rejected message.

This leads to extremely popular work around answers like
https://stackoverflow.com/questions/54099722/how-to-connect-r-to-mysql-
failed-to-connect-to-database-error-plugin-caching/54101124#54101124
which is very good for popularity scores, but not users.

It was reported in Debian https://bugs.debian.org/cgi-
bin/bugreport.cgi?bug=962597 ( for perl connectors) but wasn't fixed for
buster.

As Ubuntu is also linking against gnutls the sha256_password.so probably
isn't possible. Something to do with missing OEPC(?) missing from
gnutls. This has limited use so its a significant problem if this can't
be added.

MariaDB is fixing this in their upstream packages
(https://jira.mariadb.org/browse/MDEV-24728) from 10.2+ on all debian
and ubuntu versions
https://github.com/MariaDB/server/commit/57531b32774ffafcd2b8da763c4da859380e3f7d
).

This applies to focal only. As this is the distribution that includes
MySQL-8.0 this is important for local database connections.

groovy includes caching_sha2_password but not sha256_password
https://packages.ubuntu.com/groovy/amd64/libmariadb3/filelist

bionic is based on connector/c version is 3.0.3 however it wasn't added
upstream until 3.0.8 (https://jira.mariadb.org/browse/CONC-312).


fix: add to debian/libmariadb3.install

/usr/lib/*/mariadb19/plugin/caching_sha2_password.so

[Daniel Black]

I've updated bug 1706281. No reproducible test case yet. 1706281 is more
important that this one (if I can reproduce the fault yet).

If I don't get a confirmation for #1706281 in the next few days can you
please process this one separately.

I've also checked and the latest 5.7.20 release doesn't include a fix
for this bug.

I haven't managed to reproduce however I see no reason why the bug would
of gone away from the code changes made since the mysql versions Daniel
Axtens used when https://bugs.mysql.com/bug.php?id=80436 was written.
I'm just going to keep trying.

I see [~racb] was trying to bundle this patch with bug #1706291 however
from a logical point of view this is an independent bug.

FWIW the gdb was to show that 0 memory pages was allocated as file_size,
aka opt_tc_log_size (24k based on the minimum and default log-tc-size
setting), is less than tc_log_page_size (64k Power page size)

[Bug 1706291] Re: MySQL-5.7: default log-tc-size too small on POWER. 3 * ( 64K page size) minimum needed

[Daniel Black]

An alternate to ENABLE_DOWNLOAD

apt install googletest   (needs 1.8.0 - so zesty or artful)

sudo ln -s /usr/src/googletest /usr/src/googletest-release-1.8.0

and -DDOWNLOAD_ROOT=/usr/src in debian/rules instead of
-DENABLE_DOWNLOADS=1

unit tests will be build then.

[Bug 1706291] Re: MySQL-5.7: default log-tc-size too small on POWER. 3 * ( 64K page size) minimum needed

[Daniel Black]

On xenial. I've used the ENABLE_DOWNLOADS to get the google-mock/test
suite to get the unit test TCLogMMapTest.TClogCommit to compile.

$ sudo apt-get builddep mysql-5.7   

  
$ apt source mysql-5.7  

  
$ cd mysql-5.7-5.7.19/  

  
$ vi debian/rules   

  
add to cmake so the google-mock/test is build - getting it to use a package 
google-mock requires too much editing:

   
-DENABLE_DOWNLOADS=1 \

fyi - did more testing - seems to not to affect x86_64 - detailed test
should appear in https://lists.ozlabs.org/pipermail/linuxppc-dev soon.

[Daniel Black]

I hadn't used sshfs on Power machines before so there isn't a prior good
version.


Mainline v4.13 - jenkins-ppc64


steps on host:

virsh start {guest}

sshfs ozlabs@jenkins-ppc64:/home/ozlabs jenkins-ppc64/ -o
reconnect,idmap=user


cd jenkins-ppc64/linux

make -j 400  ; # something with a lot of read on sshfs

# on another terminal

virsh suspend jenkins-ppc64

killall -9 cc (or whatever processes is reading)

[Bug 1580794] Re: mysql-server-5.7 fails to install on box with separate /var/lib/mysql partition

[Daniel Black]

sounds root regarding mysqld --initialize.

slightly laxer option for 
mountpoint -q ${datadir} && cp my.lost_found.cnf /etc/mysql/cnf.d/

to be really prudent you could see if lost+found is empty or contains
only whatever filename extX "recovers" files to.

mariadb-server-10.0 was installed an then mysql-server-5.7 attempted to
install over the top. Their tables are different. Purge out your data
directory (/var/lib/mysql) if there is no data and try to install it
again.

This looks like you've copied some idb install files from a different
server. This isn't supported. It has to be the entire datadir. I suggest
restoring from a backup.

[Daniel Black]

seems as though zabbix-server-mysql is pulling in mysql-server-5.7 even

"InnoDB: Error number 28 means 'No space left on device'" seems pretty
conclusive to me. You can't install mysql without disk space. Your
Df.txt doesn't show it but it was out of space at the time of install.

This has been fixed by upstream commit https://github.com/mysql/mysql-

introduced into release MySQL-5.7.15.

[Bug 701522] Re: integration with ufw

[Daniel Black]

Folks,

I've done a version for upstream fail2ban here:
https://github.com/fail2ban/fail2ban/pull/489

It includes optional application support (but not ports - adding ports
would removed the simplicity of ufw in a way).

Questions:

Is 1 a sane default for insertpos? I choose it because it is likely to
work on a users set up that only run ufw enable.

Any other recommended changes?

Does it work (I haven't extensively tested it)?

[Bug 376546] Re: Identity filename completion for ssh-add would be nice

[Daniel Black]

meets the criteria above. I've used grep rather than filemagic for
efficiency.

[Bug 139674] Re: bash completion doesn't perform filename processing for ssh -i

[Daniel Black]

further to the previous comment, here is the modification to the ssh
bash_completion to handle -i searching for keys

This depends on the _ssh-add as per the (second) attachment in bug
#376546

** Patch added: patch to ssh bash completion
