I don't have anything super helpful to add, but when that git command
is hung, are you seeing any stalled network connections or processes
in D state ?

It wasn't clear from your first message. Are all native processes hanging
at do_install ? or is it a subset ?

Missing stropts.h header file - Dunfell

Sethu Madhav <sethu.m@...>
 

Hi , 
 Can anyone help to include the stropts.h header file to the dunfell . I tried adding the glibc to the image but no luck. How to include stropts.h in dunfell version. 


Re: Building a dhcp recipe separately for dhcrelay and dhclient #yocto

Vaijayanthi
 

Thanks Khem, can you please help explain or give an example of a package that is doing this? If we had separate output packages, are you suggesting we build 3 times- each time after applying a patch related to dhcrelay and dhclient?

 

We are somewhat doing this today where binaries dhcrelay and dhclient need to be built with different build options and with different patch files.

 

    

    

    git apply $WORKSPACE/git-build/dhcrelay.patch

    devtool modify dhcp

    devtool build dhcp

    cp $WORKSPACE/work/poky/build/workspace/sources/dhcp/relay/dhcrelay $OUR_WORKPSACE/dhcp/dhcrelay

 

    devtool reset dhcp

    git apply $WORKSPACE/git-build/dhclient.patch

    devtool modify dhcp

    devtool build dhcp

    cp $WORKSPACE/work/poky/build/workspace/sources/dhcp/relay/dhclient $OUR_WORKPSACE/dhcp/dhclient

do_install hangs on native tasks

Christopher Friedt
 

Hey all,

I've done some digging with this myself, but have not found a root
cause, fix, or workaround. Google shows me that a number of other
users have encountered this problem as well with Yocto, but I have not
found a solution with those either.

Native targets are stuck in the do_install phase and can literally
hang for days.

Currently 2 running tasks (2004 of 2078) 96%
...
0: nativesdk-dtc-1.6.0-r0 do_install - 1h17m52s (pid 2572369)
1: nativesdk-kmod-27-r0 do_install - 1h16m2s (pid 2656202)

Does anyone have any debugging suggestions?

$ strace -p 2572369
strace: Process 2572369 attached
pselect6(15, [12 14], [], [], {tv_sec=0, tv_nsec=526887424}, NULL) = 0 (Timeout)
wait4(2572898, 0x7ffd153a439c, WNOHANG, NULL) = 0
pselect6(15, [12 14], [], [], {tv_sec=0, tv_nsec=526887424}, NULL) = 0 (Timeout)
wait4(2572898, 0x7ffd153a439c, WNOHANG, NULL) = 0
pselect6(15, [12 14], [], [], {tv_sec=0, tv_nsec=526887424}, NULL) = 0 (Timeout)
wait4(2572898, 0x7ffd153a439c, WNOHANG, NULL) = 0
...

$ ps -fw 2572368
... /bin/sh ... temp/run.do_install.2572369

I can send a signal to the parent process (e.g. kill -USR1 2572368)
but then the process fails. I can do a clean on the targets, but the
exact same problem repeats itself.

Manually stepping through build phases also does not work, as
do_install simply hangs again when I get there.

It seems to be a pretty serious problem and not an isolated issue.
Complete showstopper, as the Yocto build cannot proceed beyond this
point without manual hacks.

I've encountered this while building the Zephyr SDK [1] on a company
machine (where it actually matters) but am unable to reproduce the
issue inside of a
centos-stream-9 docker container [2] (where it doesn't matter).

I've tried rebooting, completely wiping all of the build directories,
standing on one foot, trying to forget about it, sleeping on it, etc.
Nothing seems to fix the issue.

So yea, the fun continues!

Any ideas?

Hello Khem Raj,

Second, way would be to have test.service copies installed under

This seems to be a better solution for my use case. But, I didn't understand it completely. Could you please provide an example or any link to documentation? Is it also needed to create a custom distribution? This layer will be used by different customers in bblayers.conf

Yocto Project Newcomer & Unassigned Bugs - Help Needed

Stephen Jolley
 

All,

 

The triage team is starting to try and collect up and classify bugs which a newcomer to the project would be able to work on in a way which means people can find them. They're being listed on the triage page under the appropriate heading:

https://wiki.yoctoproject.org/wiki/Bug_Triage#Newcomer_Bugs  Also please review: https://www.openembedded.org/wiki/How_to_submit_a_patch_to_OpenEmbedded and how to create a bugzilla account at: https://bugzilla.yoctoproject.org/createaccount.cgi

The idea is these bugs should be straight forward for a person to help work on who doesn't have deep experience with the project.  If anyone can help, please take ownership of the bug and send patches!  If anyone needs help/advice there are people on irc who can likely do so, or some of the more experienced contributors will likely be happy to help too.

 

Also, the triage team meets weekly and does its best to handle the bugs reported into the Bugzilla. The number of people attending that meeting has fallen, as have the number of people available to help fix bugs. One of the things we hear users report is they don't know how to help. We (the triage team) are therefore going to start reporting out the currently 418 unassigned or newcomer bugs.

 

We're hoping people may be able to spare some time now and again to help out with these.  Bugs are split into two types, "true bugs" where things don't work as they should and "enhancements" which are features we'd want to add to the system.  There are also roughly four different "priority" classes right now,  “4.2”, “4.3”, "4.99" and "Future", the more pressing/urgent issues being in "4.2" and then “4.3”.

 

Please review this link and if a bug is something you would be able to help with either take ownership of the bug, or send me (sjolley.yp.pm@...) an e-mail with the bug number you would like and I will assign it to you (please make sure you have a Bugzilla account).  The list is at: https://wiki.yoctoproject.org/wiki/Bug_Triage_Archive#Unassigned_or_Newcomer_Bugs

 

Thanks,

Your email prompted me to check my own software (Dropbear) and it showed a
few y2038 issues to fix. Those bugs wouldn't be noticed from a quick test -
it "only" prevented auth and idle timeouts from occurring.

gcc and clang are able to flag truncated conversions for 64-bit time_t with 
-Wconversion, but that's very noisy. Comparing that against a 32-bit time_t
build, however, gives a pretty clean list of code that needs attention.

As an experiment I've built OpenBMC with and without 64-bit time_t,
https://github.com/mkj/yocto-y2038 has the results and a description. There
are a mix of false positives (particularly tv_usec/tv_nsec), but also some
real-looking things. As an example, busybox using a uint32_t to copy a dhcpd
lease expiry.

I'm not sure the best way to use these logs - they need manual review.
Expanding the list of packages should be easy, but there will be more that
need manual intervention to get rid of -Werror.
That is really interesting data as it confirmed there are real world
issues which changing the compiler flags is going to break. Thanks for
sharing.

What you describe is relatively easy for a maintainer to do as a one
off check but not really something we can do at scale for all the
software we build. It worries me :/. I guess the one upside is that
whilst it did break some functionality, it didn't actually crash the
runtime if I understand what happened correctly.

I'm not sure this should stop our plan to switch the flags but it is
certainly something to think about and be aware of.

Cheers,

Richard


systemd-timesyncd: set specific default mtime value for /var/lib/systemd/timesync/clock

Dennis Lambe <dennis@...>
 

systemd-timesyncd uses /var/lib/systemd/timesync/clock to maintain a monotonic system time across reboots even in the presence of RTC failures. If this file doesn't exist, "at the minimum, it will be set to the systemd build date".

I dug through systemd's build process, and found that it will get that build date from either the timestamp of the NEWS file or, if it's set, the environment variable SOURCE_DATE_EPOCH. So, great, that means this is already accessible through Yocto's reproducible build infrastructure. But the catch is, that variable is listed in BB_BASEHASH_IGNORE_VARS, meaning that just setting SOURCE_DATE_EPOCH from a bbappend or SOURCE_DATE_EPOCH:pn-systemd from a conf file doesn't actually cause the recipe to be re-run when I change the SOURCE_DATE_EPOCH. It also means that other developers with their own sstate might continue creating builds for themselves indefinitely that don't take my SOURCE_DATE_EPOCH into account, until such time as they happen to run a -c clean or systemd's recipe gets upgraded for another reason.

I don't think I want to remove SOURCE_DATE_EPOCH from the BB_BASEHASH_IGNORE_VARS globally, but removing it from BB_BASEHASH_IGNORE_VARS with a systemd_%.bbappend appears to have no effect (even though `bitbake -e systemd` shows that my :remove is being processed correctly).

A hack that I've thought of is setting PR .= ".${SOURCE_DATE_EPOCH}" but I can't help thinking there must be a better way.

Anybody have any advice on how to get Yocto to do what I want it to?

Few things comes to mind. You could deploy the systemd unit fragment strategy
https://wiki.archlinux.org/title/systemd#Drop-in_files
so any customizations you have could be done via these drop-ins and
keeping common service file
these drops can be then controlled via customer distro specific
override in your main bb itself.

Second, way would be to have test.service copies installed under
files/<customer-override>/ directory next to recipe
and then define customer distro specific overrides


I assume this might be the use case of many people..

Could you be more specific here? Would you like to disable some
syscalls?
I'm meaning disabling the 32 bit glibc time functions.
Some time ago I filed
https://bugzilla.yoctoproject.org/show_bug.cgi?id=6803 as Debian
has a nice sanity check where it warns if non-LFS glibc functions
are used. I imagine the same logic could be used to check for 32-
bit time_t use.
That sounds interesting and something we should probably look into for
both issues...
I have a working sanity checker that checks for any glibc functions
affected by -D_FILE_OFFSET_BITS=64 or -D_TIME_BITS=64.
The INSANE_SKIP functionality needs some more polish but I'd be happy to
contribute it.

Some libraries use both 32 and 64 bit APIs to glibc and needs exceptions
in the checker.

I have not run any world builds with this checker, I've focused on the
recipes we actually use so far so we could get to a testable system. My
biggest worry at the moment is rust, I know to little to know if it is
an actual problem and how to fix it.

I would like to be part of any "y2038 team" for Yocto.
That does sound useful, perhaps sharing it as an RFC patch might be a
good place to start? We might be able to run one of the autobuilder
world targets against it, see how it looks for our core recipes?
That works for me. I've started preparing a patch for oe-core.
