* su: fix lastlog and btmp loggingKarel Zak2013-09-091-4/+1Star
| | | | | | | | | | | | | | | | The su(1) logging code mix ups "old" and "new" passwd structs. The result is things like Sep 9 11:50:45 x2 su: (to kzak) kzak on none in /var/log/messages. The right log entry is Sep 9 11:50:45 x2 su: (to root) kzak on pts/3 The bug has been introduced by commit c74a7af17c7a176c358dfaa8e1814786c89ebc14.

* utmpdump: make IPv6 addresses workSami Kerola2013-08-291-9/+13
| | | | | | | | | | | | (unless bug[s]) This change is backwards compatibile. Earlier binary to text dumps can be converted back to binary, or otherway around. The only thing that will not work are IPv6 addresses that possible earlier conversion had broke. Such conversions resulted with random IPv4 in place of IPv6 address in text format, and original information is gone forever. Signed-off-by: Sami Kerola <kerolasa@iki.fi>
* last, utmpdump, agetty, wall, write: avoid compatibility hacksSami Kerola2013-08-292-24/+37
| | | | | | | | In include/bits/utmp.h the ut_user and ut_time macros are marked with comment they are backwards compatibility hacks. It is probably best to avoid use of these macros where ever possible. Signed-off-by: Sami Kerola <kerolasa@iki.fi>
* last: tell verbally system is still runningSami Kerola2013-08-291-2/+11
| | | | | | | | | Use of uptime time stamp as previous boot login time makes the output not constant, which is rather difficult to test. Verbal message 'system is still running' makes testing easy, and noticing which boot is still running clear to a person. Signed-off-by: Sami Kerola <kerolasa@iki.fi>

| | | | | | | When a session time will reach whopping 10000 days the last round bracket is unnecessarily removed from output. Signed-off-by: Sami Kerola <kerolasa@iki.fi>

* last: add --time-format with iso-8601 formatSami Kerola2013-08-291-23/+111
| | | | | | | | | The ISO-8601 format makes consuming time stamps easy with various parsers. The format includes time zone information which is crucial when an investigator is trying to make sense outputs collected from systems all a across planet. Signed-off-by: Sami Kerola <kerolasa@iki.fi>
* last: use configuration structSami Kerola2013-08-291-98/+113
| | | | | | | | This allows reducing global variables and will minimize number of arguments for functions making code a little bit easier to read, and maintain. Signed-off-by: Sami Kerola <kerolasa@iki.fi>

* lib/time-util: move YYYYMMDDHHMMSS to common parserSami Kerola2013-08-291-45/+0Star
| | | | | | | | | Even while the YYYYMMDDHHMMSS time format it not magnificent it is best to make it to be part of the one, and only, time format parser. Proposed-by: Karel Zak <kzak@redhat.com> References: http://markmail.org/message/6baqt4ttkopu7ra6 Signed-off-by: Sami Kerola <kerolasa@iki.fi>

* su: suppress PAM info messages for -c or non-login sessionsKarel Zak2013-08-271-2/+21
| | | | | | | | | | | | | | | | | | | | | | | | | The 'Last login:' messages from PAM lastlogin module is unexpected for non-login sessions or when -c <command> executed. For example: $ su - -c id Last login: Wed Jul 24 08:36:28 CEST 2013 from dhcp-25-161.brq.redhat.com on pts/18 uid=0(root) gid=0(root) skupiny=0(root) this makes 'su' useless in scripts. This patch suppress all PAM_TEXT_INFO messages for -c and for non-login session ('-' is not specified) after pam_authenticate() and pam_acct_mgmt(). Note that the new PAM conversation function checks the first message in the msg[] array only. It seems good enough as PAM internally uses pam_info() function that does not use multiple messages for one conv call.

* last: remove broken codeSami Kerola2013-08-231-36/+0Star
| | | | | | | | | | | Comment in the deletion tells everything necessary. "This doesn't work on modern systems, where only a DNS lookup of the result from hostname() will get you the domainname. Remember that domainname() is the NIS domainname, not DNS. So basically this whole piece of code is bullshit." Signed-off-by: Sami Kerola <kerolasa@iki.fi>
* last: prefer enum rather than #definition listSami Kerola2013-08-231-7/+9
| | | | | | | Incremental number lists are more hard to get wrong with enum, and they are nicer to debug as for example gdb is aware of these symbolic names. Signed-off-by: Sami Kerola <kerolasa@iki.fi>
* last: make switch cases complete, and inform if impossible occursSami Kerola2013-08-231-0/+11
| | | | | | | | | | Some of the ut_type numbers does not seem to be recognized by last(1) so they are, at least for now, silently ignored.
