Description pikku42 2018-12-11 20:24:26 UTC

SUMMARY


STEPS TO REPRODUCE
1. Open a PDF file in Okular
2. Select File -> Print (to any printer)

OBSERVED RESULT
File does not print. No error messages are produced in GUI. In terminal Okular outputs "/usr/bin/lpr: Error - unable to access "/tmp/okular_kpTnys.ps" - Permission denied".
The file /tmp/okular_kpTnys.ps is created with the following permissions:
---------- 1 pikku pikku 5998450 dec 11 21:13 /tmp/okular_kpTnys.ps
The same PDF file prints OK from Evince. Printing also works OK from other KDE apps.
If I catch the file and chmod it to 777 upon creation with inotifywait, the PDF prints OK.

EXPECTED RESULT
The temporary file is created readable, lpr can read it and prints it to the selected printer.

Comment 1 Albert Astals Cid 2018-12-12 23:08:11 UTC

My vote goes to: Your tmp filesystem is broken.

Since the code for printing has not changed in years and you're the first person with this problem.

I doubt i'll put any time on this, but which kind of tmp filesystem to do you use? which are the permissions of /tmp ? And any other thing you can think of.

Thanks for the reply. My /tmp is on the root of /dev/sda2 as ext4 and 
has these permissions:
drwxrwxrwt  21 root root       12288 dec 13 20:05 tmp
The system umask is 0022 as per default.
If I touch a file in /tmp from a terminal (or Dolphin or any other app 
for that matter) as a user it gets the correct permissions:
-rw-r--r-- 1 pikku pikku 0 dec 13 20:05 /tmp/jeee
As the owner of the file I can write to it and delete it.

If I try to print with Okular the temporary file gets these permissions:
---------- 1 pikku pikku 5998450 dec 13 20:09 /tmp/okular_pvmIYb.ps
and it lpr reports this on console:
/usr/bin/lpr: Error - unable to access "/tmp/okular_pvmIYb.ps" - 
Permission denied
To work around this I can have the following running whenever I need to 
print from Okular:
inotifywait -mrq -e CREATE --format %w%f /tmp/ | while IFS= read -r 
FILE; do chmod 777 "$FILE"; done &

My first thought was that there's something wrong with the /tmp but as 
far as I can tell everything is as it should be. Other programs don't 
seem to have problems with writing to/reading from /tmp. I get this 
behaviour only from Okular. Other KDE/Qt apps (just tested Konsole, 
Kate, KWrite, Kig and Konqueror) print normally.
I found this thread: https://bbs.archlinux.org/viewtopic.php?id=236004 
where the OP describes similar behaviour but in all apps and having to 
reinstall them to get them working again wihout knowing what the problem 
was.

In the meantime I have also found out that Okular is unable to save any open file (it gives a message like "File could not be saved in '/tmp/okular.xWxCSb'. Try to save it to another location.", although the selected file name for saving was "/home/pikku/test.pdf").

Investigating a bit further with audit brought me to this (note that the files apparently created by printer driver have mode 600, while the last one (/tmp/okular_KrPKrq.ps) has mode 000:

Comment 3 lkittler 2019-02-18 13:07:43 UTC

I checked strace for printing with okular and I saw that the ps file is created in /proc/<userid>/fd with access code 0 and then do a linkat on /tmp/*ps.
I can print if I start printing by "firejail okular".
