libcacard: initial commit
libcacard emulates a Common Access Card (CAC) which is a standard for smartcards. It is used by the emulated ccid card introduced in a following patch. Docs are available in docs/libcacard.txt Signed-off-by: Alon Levy <alevy@redhat.com> --- changes from v24->v25: * Fix out of tree builds. * Fix build with linux-user targets. changes from v23->v24: (Jes Sorensen review 2) * Makefile.target: use obj-$(CONFIG_*) += * remove unrequired includes, include qemu-common before qemu-thread * required adding #define NO_NSPR_10_SUPPORT (harmless) changes from v22->v23: * configure fixes: (reported by Stefan Hajnoczi) * test a = b, not a == b (second isn't portable) * quote $source_path in case it contains spaces - this doesn't really help since there are many other places that need similar fixes, not introduced by this patch. changes from v21->v22: * fix configure to not link libcacard if nss not found (reported by Stefan Hajnoczi) * fix vscclient linkage with simpletrace backend (reported by Stefan Hajnoczi) * card_7816.c: add missing break in ERROR_DATA_NOT_FOUND (reported by William van de Velde) changes from v20->v21: (Jes Sorensen review) * use qemu infrastructure: qemu-thread, qemu-common (qemu_malloc and qemu_free), error_report * assert instead of ASSERT * cosmetic fixes * use strpbrk and isspace * add --disable-nss --enable-nss here, instead of in the final patch. * split vscclient, passthru and docs to following patches. changes from v19->v20: * checkpatch.pl changes from v15->v16: Build: * don't erase self with distclean * fix make clean after make distclean * Makefile: make vscclient link quiet Behavioral: * vcard_emul_nss: load coolkey in more situations * vscclient: * use hton,ntoh * send init on connect, only start vevent thread on response * read payload after header check, before type switch * remove Reconnect * update for vscard_common changes, empty Flush implementation Style/Whitespace: * fix wrong variable usage * remove unused variable * use only C style comments * add copyright header * fix tabulation Signed-off-by: Alon Levy <alevy@redhat.com> libcacard: fix out of tree builds
