Renato Botelho d32a66b2a2 When passwd or group information is changed (by pw, vipw, chpass, ...) ... temporary file is created and then a rename() call move it to official file. This operation didn't have any check to make sure data was written to disk and if a power cycle happens system could end up with a 0 length passwd or group database. There is a pfSense bug with more infor about it: https://redmine.pfsense.org/issues/4523 The following changes were made to protect passwd and group operations: * lib/libutil/gr_util.c: - Replace mkstemp() by mkostemp() with O_SYNC flag to create temp file - After rename(), fsync() call on directory for faster result * lib/libutil/pw_util.c - Replace mkstemp() by mkostemp() with O_SYNC flag to create temp file * usr.sbin/pwd_mkdb/pwd_mkdb.c - Added O_SYNC flag on dbopen() calls - After rename(), fsync() call on directory for faster result * lib/libutil/pw_util.3 - pw_lock() returns a file descriptor to master password file on success Differential Revision: https://reviews.freebsd.org/D2978 Approved by: bapt Sponsored by: Netgate		2015-07-02 17:30:59 +00:00
