app-crypt/gnupg-2.0.28, using USB use flag, still trys to launch scdaemon from /usr/libexec/scdaemon - USB use flag states: (Restricted to >=app-crypt/gnupg-2.0.17-r1) Build direct CCID access for scdaemon; requires dev-libs/libusb. - SMARTCARD use flag states: (Restricted to <app-crypt/gnupg-2.0.17-r1) Bring in dev-libs/libusb as a dependency; enable scdaemon. So it /seems to me/ that the new USB use flag is failing to enable scdaemon. $ gpg --card-status gpg: can't connect to the agent - trying fall back gpg-agent[13338]: can't connect to the SCdaemon: IPC connect call failed gpg: OpenPGP card not available: No SmartCard daemon $ gpg-agent --server --debug-level=guru gpg-agent[13375]: enabled debug flags: command mpi crypto memory cache memstat hashing assuan gpg-agent[13375]: chan_5 -> OK Pleased to meet you OK Pleased to meet you SCD HELP gpg-agent[13375]: chan_5 <- SCD HELP gpg-agent[13375]: no running SCdaemon - starting it gpg-agent[13375]: chan_7 <- ERR 67109133 can't exec `/usr/libexec/scdaemon': No such file or directory gpg-agent[13375]: chan_7 -> BYE gpg-agent[13375]: can't connect to the SCdaemon: IPC connect call failed gpg-agent[13375]: chan_5 -> ERR 67108983 No SmartCard daemon <GPG Agent> ERR 67108983 No SmartCard daemon <GPG Agent> Reproducible: Always Steps to Reproduce: (Clear out your gnupg installed programs) (Install latest unmasked app-crypt/gnupg) 1.

I should go ahead and state, running the gpg and gpg-agent commands as root, with and w/out pcscd running, make no difference in the already provided output. Also, thank you!
Gave this a shot on the latest Gentoo LiveDVD image running in a VM. I wasn't able to gain access to the yubikey with pcsc_tools, but I don't believe that is relevant to gnupg continuing to provide the same output. The scdaemon would access it (and fail), but gnupg can't access the scdaemon. https://bpaste.net/show/1709d6c87ff0
2.0.28 ebuild does seem to contain instructions to enable scdaemon. However, the 2.0.28 ebuild does not declare the libexec dir as done in the 1.4.19 ebuild. The 2.0.28 ebuild does seem to create a few symlinks in the /usr/libexec dir, but not for scdaemon. However, I believe I searched the machine for any file name containing scdaemon and found none; I need to confirm that statement. From gnupg-2.0.28.ebuild: ( https://gitweb.gentoo.org/repo/gentoo.git/tree/app-crypt/gnupg/gnupg-2.0.28.ebuild?id=914100df67e290823ce724d8c8092fe0c587b6fe ) src_configure() { ... if use smartcard; then myconf+=( --enable-scdaemon $(use_enable usb ccid-driver) ) else myconf+=( --disable-scdaemon ) fi ... } src_install() { ... dosym gpg2keys_hkp /usr/libexec/gpgkeys_hkp dosym gpg2keys_finger /usr/libexec/gpgkeys_finger dosym gpg2keys_curl /usr/libexec/gpgkeys_curl if use ldap; then dosym gpg2keys_ldap /usr/libexec/gpgkeys_ldap fi ... } From gnupg-1.4.19.ebuild: ( https://gitweb.gentoo.org/repo/gentoo.git/tree/app-crypt/gnupg/gnupg-1.4.19.ebuild?id=58fd093c9f7947b53321a0b5f705b28657980a1e ) src_configure() { ... econf \ ... --libexecdir="${EPREFIX}/usr/libexec" \ --enable-noexecstack \ CC_FOR_BUILD=$(tc-getBUILD_CC) \ ${myconf} }
Confirmed, no scdaemon on this system: $ sudo find / -xdev -iname '*scdae*' /usr/share/man/man1/scdaemon.1.bz2 $ Enabled build logging and grepped it. Turns out the ebuild is, for some reason, declaring --disable-scdaemon: ./configure --prefix=/usr --build=x86_64-pc-linux-gnu --host=x86_64-pc-linux-gnu --mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc --localstatedir=/var/lib --disable-dependency-tracking --disable-silent-rules --libdir=/usr/lib64 --docdir=/usr/share/doc/gnupg-2.0.28 --enable-gpg --enable-gpgsm --enable-agent --enable-large-secmem --without-adns --disable-scdaemon --enable-symcryptrun --enable-bzip2 --enable-nls --disable-mailto --enable-ldap --with-readline CC_FOR_BUILD=x86_64-pc-linux-gnu-gcc config.status: creating scd/Makefile Evaluating the ebuild logic...
Seems there is a logic error in the ebuild. Looking at equery u app-crypt/gnupg we see: - - smartcard : (Restricted to <app-crypt/gnupg-2.0.17-r1) Bring in dev-libs/libusb as a dependency; enable scdaemon. + + usb : (Restricted to >=app-crypt/gnupg-2.0.17-r1) Build direct CCID access for scdaemon; requires dev-libs/libusb. So for all systems running versions >=2.0.17-r1, the use flag will always be USB. Looking at the gnupg-2.0.28.ebuild we see: if use smartcard; then myconf+=( --enable-scdaemon $(use_enable usb ccid-driver) ) else myconf+=( --disable-scdaemon ) fi So for all systems running versions >=2.0.17-r1, the use flag will NOT be smartcard, and there for scdaemon will be disabled during build.
Corrected USB use flag ebuild logic error. Will attach patch momentarily. $ gpg --card-status gpg: can't connect to the agent - trying fall back scdaemon[23121]: reading public key failed: Card error scdaemon[23121]: reading public key failed: Card error scdaemon[23121]: reading public key failed: Card error Application ID ...: D2760001240102000006038245780000 Version ..........: 2.0 Manufacturer .....: Yubico Serial number ....: 03824578 Name of cardholder: [not set] Language prefs ...: [not set] Sex ..............: unspecified URL of public key : [not set] Login data .......: [not set] Signature PIN ....: forced Key attributes ...: 2048R 2048R 2048R Max.

Not sure I understand. smartcard instructs to enable smartcard support - may be multiple interfaces. usb instructs to enables the ccid drive within smartcard. So if smartcard is disabled then usb has no effect, as far as I see this is what you experience which is what the ebuild is doing.
Current use flag restrictions prevent smartcard use flag from being used, forcing USB to be used on >=app-crypt/gnupg-2.0.17-r1. USB use flag does not cause gnupg to compile w/ smartcard support, due to logic in ebuild it actually forces smartcard support to be disabled. Comment #5 identifies the root cause of this.

I have no idea why equery would show the use flag as "restricted", but have you tried enabling "smartcard" use flag anyhow?
(In reply to Kristian Fiskerstrand from comment #10) ... > I have no idea why equery would show the use flag as "restricted", but have > you tried enabling "smartcard" use flag anyhow? No, I assumed the provided tools provided correct information. It looks like that will work however.: $ cat /etc/portage/make.conf | grep smart $ sudo nano /etc/portage/make.conf Password: $ cat /etc/portage/make.conf | grep smart USE="-gtk -gnome qt4 qt3support kde X cups consolekit acl pam policykit udev udisks crypt opengl amd64 dvd alsa cdr bindist mmx sse sse2 git subversion svg bluetooth pcsc-lite smartcard" $ emerge -av --changed-use app-crypt/gnupg ...

[Yes/No] n Quitting.
Summary: - 'equery u' outputs misleading information (root cause of this ticket) - USB use flag's function is dependent on smartcard use flag being enabled, but: - - There is no warn/error message if USB is enabled, and smartcard is not. - - Enabling USB does not force enable smartcard I recommend closing this ticket as invalid, and opening a new ticket for the equery issue. I would also open a new ticket for the use flag issue, but they may be working as intended. Let me know what you think, thanks.
I do not think there is an issue in package nor an issue with equery, in time you get use to the output of the tools, the customization in gentoo is powerful.
actual issue fixed in https://bugs.gentoo.org/show_bug.cgi?id=572574
