2020-02-13scd: Print the main app name also for not fully supported cards.Werner Koch1-0/+9
* scd/app.c (send_serialno_and_app_status): Add fallback. -- The app list was only printed for apps which support the with_keygrip function. That is not the case for the netkey and otehr cards. The new fallback prints the actual app name. Signed-off-by: Werner Koch <[email protected]>

2020-01-03scd: Minor fix for readibility.Werner Koch1-1/+1
* scd/command.c (open_card_with_request): Use NULL instead of APPTYPE_NULL. -- Using the enum is wrong because a string is expected. However it did harm anything because the value of the enum is 0 and thus equivalent to NULL. Signed-off-by: Werner Koch <[email protected]>

(select_additional_application): Add mode to call new function. -- This option is currently only useful for Yubikeys and basically ignored with other cards. Its use is SERIALNO --all LEARN --force --multi which will then print keypairinfo and other stuff for the OpenPGP and PIV application of a Yubikey.

2019-06-21scd: Take the lock earlier in the function dispatchers.Werner Koch1-113/+154
* scd/app.c: Chnage all function dispatcher. -- This change will allow us to easier integrate an app swithcing logic. The change should have no user visible effect. The error checking we do now with the card locked will rarely be asserted. It is the correct thing to do anyway. Signed-off-by: Werner Koch <[email protected]>
2019-06-21scd: Add code to check whether app switching is possible.Werner Koch1-15/+28

Change callers to use this or app_ref. * scd/command.c (open_card_with_request): (cmd_pksign, cmd_pkauth, cmd_pkdecrypt): Use app_ref and app_unref instead of accessing the counter directly. -- This is better in case we need to debug stuff. There is a real change however: We now lock and unlock the app before changing the reference count. The whole app locking business should be reviewed because we pass pointers along without immediately bumping the refcount. Signed-off-by: Werner Koch <[email protected]>
2019-06-17scd: Slight change to app->fnc.do_with_keygrip.Werner Koch1-3/+21

* scd/app.c (app_new_register): Don't lock APP_LIST_LOCK here. (select_application): Lock with APP_LIST_LOCK earlier. -- What we want to do here is to serialize the call of select_application. In the old code, it was possible that a call of select_application was blocked internally, and then another call of select_application entered. We can have a dedicated lock for call of select_application, but it is easier to re-use APP_LIST_LOCK. Signed-off-by: NIIBE Yutaka <[email protected]>
