Description Attila Tóth 2016-10-18 07:57:34 UTC

If CONFIG_UNUSED_SYMBOLS is not selected in kernel config, many addons of the package will complain about missing symbols.
The ebuild should rather check for that CONFIG probably in pkg_setup besides other condig checks already there.

okay, i version bumped to 2.12 and added UNUSED_SYMBOLS.  Please test and reopen this bug if its still a problem.

Sorry, but i suggest this report has to be reconsidered. There was no evident cases described with missing symbols messages so it's unclear whether they are related to
CONFIG_UNUSED_SYMBOLS=y. I believe something tested but it's not possible to judge.
According to:
http://cateee.net/lkddb/web-lkddb/UNUSED_SYMBOLS.html
this kernel option should not be used unless there good reason for the opposite. Before that xtables-addons had no runtime malfunctioning with this option disabled. Now, with 2.12 release, this option check is forced in ebuild.
Please, provide more additional information and research why it's needed.

I've reported this symptom, which was solved by enabling this option in my case.
I have to re-check to confirm, that the ebuild works without it.

Comment 4 Oleh 2017-02-16 07:58:48 UTC

that's right.
no exact messages, logs and runtime misfunction of addons due to this option disabled ever shown. 2.11 worked good, older than 2.11 also worked and i believe that 2.12 supposed to work too. If you give 100% evidence that this option disabled harfmul to xtables-addons, describe it. Otherwise, i'll not recommend using CONFIG_UNUSED_SYMBOLS=y as this is what kernel upstream suggests.

Some relevant kernel options changed. I was wrong about CONFIG_UNUSED_SYMBOLS.
The culprit kernel option is: CONFIG_TRIM_UNUSED_KSYMS. It's unset by default. So problem arises only if somebody explicitly enables it.
This option is accessible in the Enable loadable module support section of the kernel config.

Comment 7 Oleh 2017-02-19 05:05:47 UTC

thx,
ebuild MUST not check for CONFIG_UNUSED_SYUMBOLS, then. Please change a status of bug report.
CONFIG_TRIM_UNUSED_KSYMS  SHOULD not be set in kernel config and ebuild has to check that, otherwise.

i haven't use xtable-addons for a while.  can you guys clear this up and tell me what to commit.  or is it sufficient just to revert the last change.

Comment 9 Attila Tóth 2017-02-22 21:00:08 UTC

Created attachment 464752 [details, diff]
proposed ebuild patch for blueness

I think it should look like this.
