* MFC r285742:ed2015-08-201-0/+8
| | | | | | | | | | | | | | Unbreak "last reboot". According to the last(1) man page, the "reboot" pseudo-user should print all system reboot entries. This got broken by the utmpx import, as records are typed. Re-add support for "last reboot" by specifically matching against SHUTDOWN_TIME and BOOT_TIME records. PR: 168844 Submitted by: matthew@

* Make last(1) display the full log file.ed2010-01-191-10/+9
| | | | | | | | | | | | I must have misread when I ported the original last(1) source code. Instead of only processing the last 1024 entries, it reads them in in chucks of 1024 entries at a time. Unfortunately we cannot walk through the log file in reverse order, which means we have to allocate a piece of memory to hold all the entries. Call realloc() for each 128 entries we read.

* Port last(1) to use utmpx.ed2010-01-131-102/+83
| | | | | | | | | | | | | Basically there are three major things I changed about last(1): - It should use ut_type instead of determining by hand what type of record was given. - It should now keep track of ut_id's instead of TTYs. This means the ttylist has been renamed to the idlist, storing all the ut_id's it has processed until the next reboot. - I've removed the signal handler. Because our wtmp is rotated so often, it makes little sense. Even on a simple piece of hardware it should be capable of grinding through megabytes of logs in a second.
