2015-04-15Avoid using inet_ntoa() twice in a single printf() parameter listKenneth R Westerback
by caching the results from excess inet_ntoa() calls before doing the printf(). Should improve usefullness (?) of DHCPRELEASE log entries by actually printing ciaddr and giaddr correctly when dhcprelays stand between servers and clients. Looks good to dlg@.
2015-03-13remove the first comma from constructs like ", and," and ", or,": you can useJason McIntyre
"and" and "or" to join sentence clauses, and you can use commas, but both hinders reading;
2015-02-10Keep track of the last time we scanned the leases to find expiredKenneth R Westerback
ones that needed to be booted out of the pf table process. This avoids removing the same addess over and over. Problem report and original diff from Bertrand Provost.
2015-02-07Close appropriate ends of pfpipe. Lets pf table process die when dhcpdKenneth R Westerback
does. Pointed out by Bertrand Provost. ok henning@
2015-02-05The pf table process should die if the pipe to the dhcpd process isKenneth R Westerback
closed. e.g. dhcpd has been killed. ok henning@
2015-01-21Include <netinet/in.h> before <net/pfvar.h>. In a future change whenTheo de Raadt
ports is ready, <net/pfvar.h> will stop including a pile of balony.
2015-01-16Replace <sys/param.h> with <limits.h> and other less dirty headers whereTheo de Raadt
possible. Annotate <sys/param.h> lines with their current reasons. Switch to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_NAME_MAX, etc. Change MIN() and MAX() to local definitions of MINIMUM() and MAXIMUM() where sensible to avoid pulling in the pollution. These are the files confirmed through binary verification. ok guenther, millert, doug (helped with the verification protocol)
2014-11-22/dev/random has created the same effect as /dev/arandom (and /dev/urandom)Theo de Raadt
for quite some time. Mop up the last few, by using /dev/random where we actually want it, or not even mentioning arandom where it is irrelevant.
2014-11-15Reduce instances of `` '' in manuals.Anthony J. Bentley
troff displays these as typographic quotes, but nroff implementations almost always print them literally, which rarely has the intended effect with modern fonts, even in stock xterm. These uses of `` '' can be replaced either with more semantic alternatives or with Dq, which prints typographic quotes in a UTF-8 locale (but will automatically fall back to `` '' in an ASCII locale). improvements and ok schwarze@
2014-11-11Tweak the the DHCPACK to DHCPINFORM log entry so that it isKenneth R Westerback
less threatening and more informative. e.g. DHCPACK on <null address> to 5c:51:4f:56:81:c3 via em0 changes to DHCPACK to 192.168.19.62 (3c:97:0e:0c:0c:d7) via em0 Issue noted and diff tested by Marc Peters. Thanks! ok yasuoka@ millert@

Spotted by sthen@.
2013-04-19Log (at LOG_INFO) which interfaces dhcpd listens to and (as suggested byStuart Henderson
krw) their address. As dhcpd uses BPF, it's not possible to find this information out from fstat/netstat. ok krw@
2013-04-17Replace hand-rolled date printing/parsing code with strftime()/strptime().Kenneth R Westerback
Use timegm() because all the dates are in UTC and the 'standard' routines can't handle the truth. Remove some 'time_t is 32bits' assumptions. Print 'UTC' at the end of dates in the leases file, rather than mentioning that all dates are UTC in a comment at the top of the file. Feedback and suggestions from guenther@, kettenis@, otto@, tedu@, deraadt@.
2013-04-13Give struct dhcp_synctlv_lease fields a prefix (lv_) as the fieldsKenneth R Westerback
in other structs have. Reduces potential for confusion with fields of same name but different types in leases. Use consistent variable name. No change to executable.
