* When passwd or group information is changed (by pw, vipw, chpass, ...)Renato Botelho2015-07-022-3/+21

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

* - Commit work from libprocstat project. These patches add support for runtimeStanislav Sedov2011-05-121-0/+5
| | | | | | | | | | | | | | | | | | | | | | | file and processes information retrieval from the running kernel via sysctl in the form of new library, libprocstat. The library also supports KVM backend for analyzing memory crash dumps. Both procstat(1) and fstat(1) utilities have been modified to take advantage of the library (as the bonus point the fstat(1) utility no longer need superuser privileges to operate), and the procstat(1) utility is now able to display information from memory dumps as well. The newly introduced fuser(1) utility also uses this library and able to operate via sysctl and kvm backends. The library is by no means complete (e.g. KVM backend is missing vnode name resolution routines, and there're no manpages for the library itself) so I plan to improve it further. I'm commiting it so it will get wider exposure and review. We won't be able to MFC this work as it relies on changes in HEAD, which was introduced some time ago, that break kernel ABI. OTOH we may be able to merge the library with KVM backend if we really need it there. Discussed with: rwatson

* Remove login(3), logout(3) and logwtmp(3) from libutil.Ed Schouten2010-01-131-4/+0
| | | | | | | | | | These functions only apply to utmp(5). They cannot be kept intact when moving towards utmpx. The login(3) function would break, because its argument is an utmp structure. The logout(3) and logwtmp(3) functions cannot be used, since they provide a functionality which partially overlaps. Increment SHLIB_MAJOR to 9 to indicate the removal.
