* | | gpg: Add "self-sigs-only" and "import-clean" to the keyserver options.Werner Koch2019-07-042-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * g10/gpg.c (main): Change default. -- Due to the DoS attack on the keyeservers we do not anymore default to import key signatures. That makes the keyserver unsuable for getting keys for the WoT but it still allows to retriev keys - even if that takes long to download the large keyblocks. To revert to the old behavior add keyserver-optiions no-self-sigs-only,no-import-clean to gpg.conf. GnuPG-bug-id: 4607 Signed-off-by: Werner Koch <[email protected]>

(handle_send_request_error): Use it for 503 and 504. (ks_hkp_search, ks_hkp_get, ks_hkp_put): Pass a new var for extra_tries. -- This is a pretty stupid fix but one which works without much risk of regressions. We could have used the existing TRIES but in that case the fallback to other host would have been too limited. With the used value we can have several fallbacks to other hosts.

If a request by gpg-connect-agent was accepted, it resulted an error by sudden shutdown. This change of the order can remove such a race. Here, we know backend=0 is none.
