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
