[pkg-gnupg-maint] Bug#849845: Bug#849845: dirmngr: Can't resolve keyserver hostname anymore

Hi Werner!

Werner Koch:

Thanks for caring! I've tried rebuilding the package currently in sid
with this patch applied, but it doesn't seem to be enough.

The first --recv-keys triggers:

  Jan 02 13:36:33 dirmngr[8281]: DBG: dns: getsrv(_hkp._tcp.hkps.pool.sks-keyservers.net): Server indicated a failure
  Jan 02 13:36:33 dirmngr[8281]: command 'KS_GET' failed: Server indicated a failure <Unspecified source>
  Jan 02 13:36:33 dirmngr[8281]: DBG: chan_5 -> ERR 219 Server indicated a failure <Unspecified source>

... which is expected if querying 127.0.0.1, that doesn't support
SRV records.

And the next attempts, after manually telling dirmngr that my
keyserver is alive:

  Jan 02 13:37:56 dirmngr[8281]: connection from process 8506 (1002:1002)
  Jan 02 13:37:56 dirmngr[8281]: DBG: chan_5 <- GETINFO version
  Jan 02 13:37:56 dirmngr[8281]: DBG: chan_5 -> D 2.1.17
  Jan 02 13:37:56 dirmngr[8281]: DBG: chan_5 -> OK
  Jan 02 13:37:56 dirmngr[8281]: DBG: chan_5 <- KEYSERVER --clear hkps://hkps.pool.sks-keyservers.net
  Jan 02 13:37:56 dirmngr[8281]: DBG: chan_5 -> OK
  Jan 02 13:37:56 dirmngr[8281]: DBG: chan_5 <- KS_GET -- 0x7C84A74CFB12BC439E81BA78C92949B8A63BB098
  Jan 02 13:37:57 dirmngr[8281]: DBG: dns: resolve_dns_name(hkps.pool.sks-keyservers.net): Success
  Jan 02 13:37:57 dirmngr[8281]: can't connect to 'hkps.pool.sks-keyservers.net': no IP address for host
  Jan 02 13:37:57 dirmngr[8281]: error connecting to 'https://hkps.pool.sks-keyservers.net:443': Unknown host
  Jan 02 13:37:57 dirmngr[8281]: marking host 'hkps.pool.sks-keyservers.net' as dead


strace still seems to indicate that resolv.conf is read, and then
127.0.0.1 is queried.

Cheers,
