2014-05-26libcacard: remove useless initializersMichael Tokarev
libcacard has many functions which initializes local variables at declaration time, which are always assigned some values later (often right after declaration). Clean up these initializers. Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>
2014-05-26libcacard: fix wrong array expansion logicMichael Tokarev
The currrent code in libcacard/vcard_emul_nss.c:vcard_emul_options() has a weird bug in variable usage around expanding opts->vreader array. There's a helper variable, vreaderOpt, which is first needlessly initialized to NULL, next, conditionally, only we have to expand opts->vreader, receives array expansion from g_renew(), and next, even if we don't actually perform expansion, the value of this variable is assigned to the actual array, opts->vreader, which was supposed to be expanded. So, since we expand the array by READER_STEP increments, only once in READER_STEP (=4) the code will work, in other 3/4 times it will fail badly. Fix this by not using this temp variable when expanding the array, and by dropping the useless =NULL initializer too - if it wasn't in place initially, compiler would have warned us about this problem at the beginning.

2014-05-24libcacard/vcard_emul_nss: Drop a redundant conditionalMarkus Armbruster
Bailing out when PK11_FindGenericObjects() returns null ensures the loop that follows it executes at least once. The "loop did not execute" test right after it is useless. Drop it.

2014-05-24libcacard/vreader: Drop broken recovery from failed assertionMarkus Armbruster
We suppress some code when we got unexpected status and assertion checking is off: assert(card_status == VCARD_DONE); if (card_status == VCARD_DONE) { int size = MIN(*receive_buf_len, response->b_total_len); memcpy(receive_buf, response->b_data, size); *receive_buf_len = size; } Such "recovery" is of dubious value even when it works. This one doesn't: it fails to assign to receive_buf[] and *receive_buf_len, which the callers expect. Make the code unconditional.

2014-05-09libcacard: remove libcacard-specific CFLAGS and LIBS from global varsMichael Tokarev
Currently all what's needed for single file libcacard/vcard_emul_nss.c (libnss cflags) and hw/usb/ccid-card-emulated.c (libcacard includes) together with the libs is added to global QEMU_CFLAGS and libs_softmmu. Use the cflags only where really used (for two mentioned files), and libs only where needed. While at it, rename variables to better reflect reality: libcacard_* is really nss_*. This needs a bit more tweaking: $(NSS_LIBS) should not contain $glib_libs (ditto for _cflags). But in order to fix it, some more preparations should be made first. So add a FIXME comment.

2014-05-07libcacard: replace pstrcpy() with memcpy()Michael Tokarev
Commit 2e679780ae86c6ca8 replaced strncpy() with pstrcpy() in one place in libcacard. This is a qemu-specific function, while libcacard is a stand-alone library (or tries to be). But since we know the exact length of the string to copy, and know that it definitely will fit in the destination buffer, use memcpy() instead, and null-terminate the string after that. An alternative is to use g_strlcpy() or strncpy(), but memcpy() is more than adequate in this place.

QEMU requires glib 2.12, so both names must not be used. Instead of showing a warning for code which should not be reached, vscclient better stop running, so g_warn_if_reached is not useful for vscclient. In libcacard/vsclient.c, g_byte_array_unref can be replaced by g_byte_array_free. This is not generally true, so adding a compatibility layer in include/glib-compat.h is no option here.
