Subject: [4.11 regression] su / sudo doesn't work when enlightenment is running as the window manager
Date: Mon, 22 May 2017 11:03:41 +0200	[thread overview]
Message-ID: <s5hy3tpntzm.wl-tiwai@suse.de> (raw)

Hi Eric,

we've got a bug report showing the weird behavior supposedly triggered
by your commit 20523132ec5d ("exec: Test the ptracer's saved cred to
see if the tracee can gain caps").  In short, user can't run su or
sudo any longer when a terminal is started from Enlighentment window
manager.

Some details are found in openSUSE Bugzilla:
  https://bugzilla.suse.com/show_bug.cgi?id=1040041

and more in gentoo forum and Enlightenment bug tracker:
  https://forums.gentoo.org/viewtopic-t-1063022-postdays-0-postorder-asc-start-0.html
  https://phab.enlightenment.org/T5470

As the bug seems solely in Enlightenment, it might that be some its
specific patch is broken.  But a regression is a regression, after
all...

Could you take a look at the issue?

Thanks!


Takashi
