libdns: Hack to skip negation term.
* dirmngr/dns.c (dns_nssconf_loadfile): Skip negation terms in nsswitch.conf parser.
This small patch was submitted along with this comment:
We've been having issues over at Arch Linux with the new libdns code. Our /etc/nsswitch.conf contains the following line: hosts: files mymachines resolve [!UNAVAIL=return] dns myhostname And it turns out dirmngr fails to parse the negation statement (the bang in !UNAVAIL). This results in gnupg not being able to resolve any name. Looking at dirmngr/dns.c it was unclear to me how to properly handle such negations. The dns_anyconf_scan calls used in dns_nssconf_loadfile do not allow to store a negation bit easily... In the meantime, I wrote the attached patch which ignores those statements altogether. It makes libdns work as expected for us.
