Description Florian Weimer 2014-11-12 13:30:04 UTC
_SC_GETPW_R_SIZE_MAX and _SC_GETGR_R_SIZE_MAX are only size *hints*.  Their names are misleading, it is not a maximum size.  snapperd should still loop around the getpwnam_r and getgrnam_r calls and allocate more memory as necessary (on the heap, not the stack).  This is required so that users in many groups and groups with many users can access snapperd.  Affected the functions get_user_uid and get_group_uids in server/MetaSnapper.cc.

Comment 2 Fedora End Of Life 2016-07-19 20:52:26 UTC
Fedora 22 changed to end-of-life (EOL) status on 2016-07-19. Fedora 22 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this

Thank you for reporting this bug and we are sorry it could not be fixed.
