I'm sorry, it was completely inappropriate...

The cause of this bug seems that lstat returns strange size of symlink on some
filesystem (for me, it returns 0 on /proc/self , /sys/bus/cpu/devices/* and so
on) and then readlink fail.

Created attachment 101724

Correcting the buffer size for readlink.

Maybe I'm encountering the same bug and found the cause.
Could you try this patch?

(Since I am not a programmer, I do not know whether this patch is appropriate.)

[frameworks-kinit] [Bug 358593] New: kdeinit5 create /tmp/xauth-xxx-_y with inappropriate permission.

[taro yamada via KDE Bugzilla]

https://bugs.kde.org/show_bug.cgi?id=358593

Bug ID: 358593
   Summary: kdeinit5 create /tmp/xauth-xxx-_y with inappropriate
permission.
   Product: frameworks-kinit
   Version: unspecified
  Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
  Severity: normal
  Priority: NOR
 Component: general
  Assignee: fa...@kde.org
  Reporter: archer_...@yahoo.co.jp
CC: kdelibs-b...@kde.org

I'm sorry if my English is hard to understand.

kdeinit5 create /tmp/xauth-xxx-_y with inappropriate permission, 644.
I think it should be 600.

---affected system---
Distro : ArchLinux
Qt version : 5.5.1 (I'm sorry, I haven't check the other versions on Arch.)
KDE version : 5.18.0 (The same as above)
--

---not affected system---
Distro : Kubuntu 15.10 LiveCD
Qt version : 5.4.2
KDE version : 5.15.0

Reproducible: Always

Steps to Reproduce:
1. Just login to plasma5. (I tried sddm and startx.)

Actual Results:  
 The permission of /tmp/xauth-xxx-_y is 644.

Expected Results:  
The permission of /tmp/xauth-xxx-_y should be 600.

I'm newbie but I tried to read the source for my study.
I changed near the line 1536 of kinit-5.18.0/src/kdeinit/kinit.cpp.
---before---
if (!xauthfrom.open(QFile::ReadOnly) || !xauthfile.open(QFile::WriteOnly)
|| xauthfile.write(xauthfrom.readAll()) != xauthfrom.size() ||
!xauthfile.commit()) {
--
to
---after---
if (!xauthfrom.open(QFile::ReadOnly) || !xauthfile.open(QFile::WriteOnly) ||
!xauthfile.setPermissions( QFile::Permissions( QFile::ReadOwner |
QFile::WriteOwner ) )
 || xauthfile.write(xauthfrom.readAll()) != xauthfrom.size() ||
!xauthfile.commit()) {
--

And remove /tmp/xauth-xxx-_y and relogin, then the permission become 600.
I don't have enough ‎knowledge, so I can't determine this is valid solution or
not.
