Subject: /proc/<pid>/exe symlink behavior change in >=3.15.
Date: Sat, 06 Sep 2014 23:44:32 +0200	[thread overview]
Message-ID: <540B8040.5010206@gmail.com> (raw)

Hi,

Starting with kernel 3.15 the 'exe' symlink under /proc/<pid>/ acts 
diffrent than it used to in all the pre-3.15 kernels.

The usecase:

run /root/testbin (app that just sleeps)
cp /root/testbin /root/testbin.new
mv /root/testbin.new /root/testbin
ls -al /proc/`pidof testbin`/exe

<=3.14: /root/testbin (deleted)
 >=3.15: /root/testbin.new (deleted)

Was the change intentional? It does render my system unusable and I 
failed to find a information about such change in the ChangeLog.

-- Piotr.
