[opensuse-factory] snapper fails to accept group in ALLOW_GROUPS
by Holger Jakob 01 Nov '16

When I try to add a group to ALLOW_GROUPS in a snapper config file I get an "invalid group" error. The issue was tracked down to getgrnam_r(): In snapper-0.3.3/snapper/AppUtil.cc get_group_gid() fails to lockup the GID when bufsize (typically 1024) is too small. I have quite a number of users in a group in /etc/group. The the buffer size is not sufficient getgrnam_r() will fail with an ERANGE error. Increasing bufsize from 1024 to 2000 seems to work and obviously removing some of the users from the group helps too. I recommend to do something like described in http://pubs.opengroup.org/onlinepubs/9699919799/functions/getgrnam.html This will ensure enough space is made available. However, I am not sure if this issue is fully fixed by a change to snapper. It seems that the order of the groups AND the number of members in the group file matters too. If getgrname_r runs across an entry with too many members any subsequent entry is answered with an ERANGE error. So even if the group that is added to ALLOW_GROUPS does not have that many users but is listed after one that does the error would still occur. I don't think working around this with MAX_MEMBERS_PER_GROUP in /etc/login.defs is any better. Note: This report was first sent to "yast-devel" as suggested on the Snapper IO page. This list however seems more appropriate for discussion. -- Holger Jakob -- To unsubscribe, e-mail: opensuse-factory+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-factory+owner(a)opensuse.org

[opensuse-factory] Fwd: Post to opensuse-factory@opensuse.org denied: KMAIL 5.3.0: no printing

Hello! I'm using KMAIL 5.3.0 and I got this error message when trying to print within KMAIL: "Die Druck-Unterstützung in WebEngine ist derzeit eingeschränkt. Für das Drucken wird ein externer Webbrowser verwendet." Using the browser makes printing possible, but not in KMAIL. I did a fresh installation of tumbleweed but it's the same. My notebook runs Tumbleweed with KMAIL 5.1.2 and there isn't an error saying that printing is only possible with the web browser. For me as a non-it-pro-user it looks like that there is no printing module in KMAIL 5.1.2 included. I can't find any printer settings in the program. Please give me some hints solving this problem! TIA!
