pepper flash doesn't work with new gcc-libs 8.3

webcapcha · 2019-04-21 07:47:17

Yesterday (20 Apr) the new gcc-libs updates to 8.3 version. With this update pepper-flash doesn't work anymore with chrome. Anybody faced the same issue?

I suspect a newer version built against the new gcc-libs would be needed, but adobe is no longer providing it:

adobe website wrote:

Starting on April 9, 2019, Shockwave player for Windows will no longer be available for download. Adobe will no longer accept ETLA and EULA agreements for Shockwave effective on April 9, 2019.

Whether this applies to the flashplugin downloaded from the same site is unclear - but it seems a likely explanation.

EDIT: wikipedia states flashplugin has a planned EOL of the end of 2020 - so perhaps this isn't it. But in either case, adobe is not (yet) providing an updated version.

If you can check `ldd` output on the .so files in the pepper-flash package to confirm one actually does link against an old gcc-libs library, then this could be submitted to the bug tracker - though the fix will still depend on adobe, it'd at least then be tracked.

If you really really need flash content in the mean time, you could try gnash or lightspark.

I found only

/usr/lib/PepperFlash/libpepflashplayer.so

Here is the output

I use flash for one game, that still using flash : (

Hmm, I guess my interpretation was wrong. That is still linked against the current gcc-libs, so unless gcc-libs had an ABI-breaking change without a soname bump, the problem is elsewhere.

What do you mean by "it doesn't work". What errors are you getting? Did you confirm that downgrading gcc-libs was sufficient to get it working again?

So, when I navigate to a site it shows me https://imgur.com/zdcAxbC. And yes I tried right click, tried clean cache, checked site permissions. Doesn't help.

No I haven't tried to downgrade a gcc on my computer (afraid doing this, due to so many dependencies). But I noticed that issue happened after this update. And as far as gcc-lib is in dependencies in pepper flash, I made such conclusion

[2019-04-20 19:29] [ALPM] upgraded binutils (2.31.1-4 -> 2.32-1)

[2019-04-20 19:29] [ALPM] upgraded python-gobject (3.32.0-1 -> 3.32.1-1)

Additionally, I have a additional computer with manjaro. And I can confirm that flash is working there. And as far as manjaro is behind arch a little, I've checked it using 8.2.0.1 version (if i remember), but for sure not 8.3

Actually downgrading gcc-libs doesn't help. It's the glibc upgrade causing the problem. I tried downgrading glibc to 2.28-6, the pepper-flash works again.

Thanks for details.

2all question, is it a long-awaited final with flash? Or it will work and we can consider it's like a "bug"

I don't know the detail of the problem or how it should be fixed. I don't have the ability to dig deeper as I'm not familiar with web browser plugins.
If it's a glibc problem, then it should be easy to fix. But if some changes of glibc require recompilation of the pepper-flash plugin, then we can only wait for adobe to release a new version.

loqs · 2019-04-21 19:19:07

If you rebuild glibc 2.28-6 with extra-x86_64-build from devtools does the glibc 2.28-6 that produces built with gcc 8.3 allow pepper flash to work?
If not then you may have to bisect between glibc 2.28 and 2.29.

Trilby · 2019-04-21 19:22:47

As another check, xiaoliniess, are you also using multilib (e.g., lib32-glibc) or are you using core/glibc?

Anyone who wants to use current build with flash could run Chromium (and all Chromium-based browsers too, at least it works with Opera) with command line argument

--disable-seccomp-filter-sandbox

I confirm this workaround can play flash games and videos. Tested on opera 60.0.3255.59.

So the next release of chromium should resolve the issue.

I am not sure because the commit was reverted a few days back because it failed Android CFI. Not sure what is going to happen now. I really need flash only for a single site.

loqs · 2019-05-05 11:54:13

@bharath23 74.0.3729.131-1 and 74.0.3729.131-2 both contained the patch was the issue still present with those versions?
