2011-10-25libcacard: Fix wrong assertion (reported by cppcheck)Stefan Weil1-1/+1
assert("...") will never do anything. This assertion handles a case which should never occur, so it must be assert(!"..."). Cc: Alon Levy <alevy@redhat.com> Signed-off-by: Stefan Weil <sw@weilnetz.de>

2011-08-27Fix build on OpenBSD with BSD userland emu and smartcard NSS enabledBrad1-2/+2
The first issue is the hard coded POSIX Real Time extensions library in the libcacard/Makefile. From looking at the code it doesn't seem this is necessary anyway. Robert Relyea seems to think it most likely isn't necessary. The second issue was the missing exclusion of the BSD userland binary builds from the addition of this Makefile target for the smartcard NSS code which breaks the builds if smartcard NSS support is enabled. pastebin clip of the build failure.. http://pastebin.com/raw.php?i=BLCKd3s6 Signed-off-by: Brad Smith <brad@comstyle.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-08-22Improvements to libtool support.Brad1-5/+5
Improvements to the libtool support in QEMU. Replace hard coded libtool in the infrastructure with $(LIBTOOL) and allow overriding the libtool binary used via the configure script.

2011-07-22libcacard: introduce NEXT_TOKEN macroChristophe Fergeau1-47/+24
vcard_emul_options now has repetitive code to read the current token and advance to the next. After the previous changes, this repetitive code can be moved in a NEXT_TOKEN macro to avoid having this code duplicated.

2011-07-22libcacard: fix soft=... parsing in vcard_emul_optionsChristophe Fergeau1-17/+28
The previous parser had copy and paste errors when computing vname_length and type_params_length, "name" was used instead of respectively vname and type_params. This led to length that could be bigger than the input string, and to access out of the array bounds when trying to copy these strings. valgrind rightfully complained about this. It also didn't handle empty fields correctly, Signed-off-by: Christophe Fergeau <cfergeau@redhat.com> Reviewed-by: Alon Levy <alevy@redhat.com>
2011-07-22libcacard: s/strip(args++)/strip(args+1)Christophe Fergeau1-2/+2
vcard_emul_options used args = strip(args++) a few times, which was not returning the expected result since the rest of the code expected args to be increased by at least 1, which is not the case if *args is not a blank space when this function is called. Replace these calls by "strip(args+1)" which will do what we expect. Signed-off-by: Christophe Fergeau <cfergeau@redhat.com> Reviewed-by: Alon Levy <alevy@redhat.com>
2011-07-22libcacard: don't leak vcard_emul_alloc_arrays memChristophe Fergeau1-1/+10
vcard_emul_mirror_card and vcard_emul_init use vcard_emul_alloc_arrays to allocate memory for temporary arrays which will contain elements that in the end will be used one by one in cac_card_init. The arrays themselves are never stored anywhere, they are only used as temporary containers. Hence the memory that was allocated for these arrays should be freed after use or they will be leaked.
2011-07-22libcacard/vcard_emul_nss: support cards lying about CKM_RSA_X_509 supportRobert Relyea1-6/+127
Some tokens claim to do CKM_RSA_X_509, but then choke when they try to do the actual operations. Try to detect those cases and treat them as if the token didn't claim support for X_509. Signed-off-by: Robert Relyea <rrelyea@redhat.com>
2011-06-14libcacard: add libcacard.la targetAlon Levy1-4/+28
No flag to configure is required. Instead, added a libcacard.la target that is not built by default, only when requested explicitly via: mkdir build cd build ../configure make libcacard.la make install-libcacard Uses libtool to do actual linking of object files and shared library, and installing. Tested only under linux, but supposed to work on other systems as well. If libtool isn't found you get a message complaining about that, only at build time (since it is not a default target I did not add a message at configure time). New build artifacts: .libs subdirectories (at <buildroot> and <buildroot>/libcacard) *.lo files (at same locations as the respective o files) Added %.lo : %.c rule that uses libtool. Updated clean rule to clean up those artifacts. Added specific rule to call dtrace with libtool wrapper (note that because of a current upstream dtrace bug fixed by systemtap b1568fd85 commit the -fPIC flag isn't actually passed on. still current dtrace+libtool produced object links fine). If libtool is missing any of the following targets will complain and exit 1: any subdir: *.lo root and libcacard: libcacard.la, libcacard-instsall Tested to link and load with all tracing backends.
