2020-02-02Tweak dhclient(8) timing defaults depending on SMALL rather than usingKenneth R Westerback
/dev/stdin to fake a dhclient.conf file during install. Simplifies and shortens install.sub code. Allows further restrictions to be applied to '-c' specified files.
2020-01-28We are not correctly upgrading from "UNKNOWN" to "VALIDATING"Florian Obser
resulting in a "fatal in resolver: wrong unified cache set on resolver". I believe this happens because we are using an UNKNOWN resolving strategy to resolve queries. Disable the upgrade logic for now and always construct a fresh resolver context and set the unified context on it before any cache gets allocated. This causes a bit of memory churn on startup and when changing networks, but better than a crashing unwind. First observed by deraadt

2020-01-23Separate command line syntax parsing from semantic validation ofKenneth R Westerback

2020-01-20We can not share a cache between validating and resolving strategies.Florian Obser
The resolving only strategies mess up the negative cache by claiming DNSSEC related records do not exist which confuses the validating strategies. Found the hard way by kn@ and analysed by otto@ OK kn@
2020-01-19add some explicit tagging macros; OK kn@ on a previous versionIngo Schwarze
2020-01-16Add '-p' command line option which allows to configuretobhe
the UDP encapsulation port, similar to isakmpd's '-N' flag. Being able to change the UDP encapsulation port is useful in cases where ESP and UDP ports 500 and 4500 are blocked or rate limited. ok sthen@

2020-01-16Fail on missing anchorkn
There is no reason to continue on anchor specific paths if the given anchor does not exist. OK sashan

Missed in previous
2020-01-15Unify error message for nonexisting anchorskn
pf(4) returns EINVAL for DIOCGETRULE, DIOCGETRULES and DIOCGETRULESET if the specified anchor does not exist. Extend and rename {pfr -> pf}_strerror() to make error message more consistent. There are other occasions as well but those need additional tweaks; that's stuff for another diff. OK and rename from sashan
2020-01-15Support multiple x509 extensions and extensions with multipletobhe

is ignored (the behaviour previously behind -6 is now the default so if this flag was used, it can happily be removed.

2020-01-15Refine error messagekn
While code in pf/pfctl confusingly uses either anchor or ruleset depending on the context, pfctl(8) (both manual and user interface) should be consistent. For users there are basically anchors only, so do not imply any difference between the two terminologies. OK sashan

2020-01-15Recent change to pfctl(8) prompts for a minor update of manpage.Alexandr Nedvedicky
OK kn@
2020-01-15Enable pfctl(8) to recursively flush rules and tables from PF driver. TheAlexandr Nedvedicky
recursive operation ("pfctl -a '*' ...") works for '-s' option already. This change enables the same thing for '-F' option, so "pfctl -a '*' -Fa" will flush everything from PF driver. The idea was discussed with many on tech@ in spring 2019. OK kn@
2020-01-15Replace duplicate error message with gai_strerror(3)kn
getaddrinfo(3) may fail for multiple reasons, but error message should be unique in general. OK bluhm
2020-01-14Remove IPsec flow blocking unencrypted IPv6 traffic which wastobhe
meant to prevent VPN leakage but repeatedly broke people's setups. The -6 flag which used to disable the blocking flow is now ignored and prints a deprecation warning. ok kn@ bluhm@ phessler@

2020-01-07Link ESP-SA and IPcomp-SA using GRPSPIS instead of using a self-builttobhe
solution for multi-SA flows. As a result we only need a single outgoing IPCOMP flow and can get rid of the two extra transport mode flows for ESP. ok bluhm@
2020-01-04ping(8): improve "-i wait" parsing and error-checking codecheloha
- Never accept negative values. - Cap the interval at UINT_MAX seconds to avoid strange rounding behavior at the end of the input range. - Use error messages that resemble other parts of the tree where we are able to use strtonum(3). - Leverage modf(3) for cleaner code. - Call it "-i interval" to avoid accidental visual similarity to "-w maxwait". With input from cjeker@, kettenis@, kn@. ok kn@

2019-12-25timeout(9): new flag: TIMEOUT_SCHEDULED, new statistic: tos_scheduledcheloha
This flag is set whenever a timeout is put on the wheel and cleared upon (a) running, (b) deletion, and (c) readdition. It serves two purposes: 1. Facilitate distinguishing scheduled and rescheduled timeouts. When a timeout is put on the wheel it is "scheduled" for a later softclock(). If this happens two or more times it is also said to be "rescheduled". The tos_rescheduled value thus indicates how many distant timeouts have been cascaded into a lower wheel level. 2. Eliminate false late timeouts. A timeout is not late if it is due before softclock() has had a chance to schedule it. To track this we need additional state, hence a new flag. rprocter@ raises some interesting questions. Some answers: - This interface is not stable and name changes are possible at a later date. - Although rescheduling timeouts is a side effect of the underlying implementation, I don't forsee us using anything but a timeout wheel in the future. Other data structures are too slow in practice, so I doubt that the concept of a rescheduled timeout will be irrelevant any time soon. - I think the development utility of gathering these sorts of statistics is high. Watching the distribution of timeouts under a given workflow is informative. ok visa@

ub_event_pluggable.c instead of ub_event.c. ( https://github.com/NLnetLabs/unbound/issues/99 ) We have been the odd one out, so switch to ub_event_pluggable, too.
2019-12-20Try to bind to port 53 before opening the control socket.Florian Obser
The bind might fail if another daemon is running while the control socket opening will succeed. Then we end up with an overwritten control socket, unwind exiting and no control socket to the already running unwind. Found the hard way by deraadt OK deraadt, mestre, kn, pamela

https://github.com/NLnetLabs/unbound/issues/99 ub_ctx_delete would free the passed in event_base leading to use-after-free since libunbound never allocated the memory and unwind expects to continue using the event_base.
