NTP users are strongly urged to take immediate action to ensure that their NTP daemons are not susceptible to being used in distributed denial-of-service (DDoS) attacks. Please also take this opportunity to defeat denial-of-service attacks by implementing Ingress and Egress filtering through BCP38.

ntp-4.2.8p15 was released on 23 June 2020. It addresses 1 medium-severity security issue in ntpd, and provides 13 non-security bugfixes over 4.2.8p13.

Please see the NTP Security Notice for vulnerability and mitigation details.

Are you using Autokey in production? If so, please contact Harlan - he's got some questions for you.

Package TWiki::Query::HoistREs

Static functions to extract regular expressions from queries. The REs can be used in caching stores that use the TWiki standard inline meta-data representation to pre-filter topic lists for more efficient query matching.

See Store/RcsFile.pm for an example of usage.

ObjectMethod hoist ($query) -> @res

Extract useful filter REs from the given query. The list returned is a list of filter expressions that can be used with a cache search to refine the list of topics. The full query should still be applied to topics that remain after the filter match has been applied; this is purely an optimisation.
