2014-05-13hw/arm/omap_gpmc: Avoid buffer overrun filling prefetch FIFOPeter Maydell1-0/+4
In fill_prefetch_fifo(), if the device we are reading from is 16 bit, then we must not try to transfer an odd number of bytes into the FIFO. This could otherwise have resulted in our overrunning the prefetch.fifo array by one byte.

2014-05-13hw/arm/stellaris: Correct handling of GPTM TAR registerPeter Maydell1-3/+10
We don't implement very much of the GPTM TAR register, and what we do is wrong. The "are we in RT mode?" field is in s->config, not s->control. Correct this, use LOG_UNIMP rather than hw_error() for the cases we don't support, and avoid an unlabelled fallthrough that makes Coverity complain.

When writing to the YEARS_REG register, if the year value is 99 then the multiplication by 31536000 will overflow into the sign bit of a 32 bit value and then be erroneously sign-extended if time_t is 64 bits.

Commit 191946c moved the code to handle padding to minimum length from after the handling of the CRC to before it. This means that the CRC code doesn't need to cope with the possibility that the size is less than 60; remove this dead code.

Convert this device to use vmstate for its save/load, including providing a post_load function that sanitizes inbound data to avoid possible buffer overflows if it is malicious. The sanitizing fixes CVE-2013-4532 (though nobody should be relying on the security properties of most of the unmaintained ARM board models anyway, and migration doesn't actually work on this board due to issues in other device models).

2014-05-13hw/net/stellaris_enet: Get rid of rx_fifo pointerPeter Maydell1-21/+19
The rx_fifo pointer is awkward to migrate, and is actually redundant since it is always possible to determine it from the current rx[].len/.data and rx_fifo_len. Remove both rx_fifo and rx_fifo_len from the state, replacing them with a simple rx_fifo_offset which points at the current location in the RX fifo.

2014-05-13hw/net/stellaris_enet: Correctly implement the TR and THR registersPeter Maydell1-2/+15
Packet transmission for the stellaris ethernet controller can be triggered in one of two ways: * by setting a threshold value in the THR register; when the FIFO fill level reaches the threshold, the h/w starts transmitting. Software has to finish filling the FIFO before the transmit process completes to avoid a (silent) underrun * by software writing to the TR register to explicitly trigger transmission Since QEMU transmits packets instantaneously (from the guest's point of view), implement "transmit based on threshold" with our existing mechanism of "transmit as soon as we have the whole packet", with the additional wrinkle that we don't transmit if the packet size is below the specified threshold, and implement "transmit by specific request" properly.

2014-05-13hw/net/stellaris_enet: Rewrite tx fifo handling codePeter Maydell1-42/+77
The datasheet is clear that the frame length written to the DATA register is actually stored in the TX FIFO; this means we don't need to keep both tx_frame_len and tx_fifo_len state separately.

2014-05-13hw/net/stellaris_enet: Correct handling of packet paddingPeter Maydell1-1/+1
The PADEN bit in the transmit control register enables padding of short data packets out to the required minimum length. However a typo here meant we were adjusting tx_fifo_len rather than tx_frame_len, so the padding didn't actually happen. Fix this bug.

2014-05-13hw/net/stellaris_enet: Restructure tx_fifo code to avoid buffer overrunPeter Maydell1-4/+6
The current tx_fifo code has a corner case where the guest can overrun the fifo buffer: if automatic CRCs are disabled we allow the guest to write the CRC word even if there isn't actually space for it in the FIFO. The datasheet is unclear about exactly how the hardware deals with this situation; the most plausible answer seems to be that the CRC word is just lost. Implement this fix by separating the "can we stuff another word in the FIFO" logic from the "should we transmit the packet now" check. This also moves us closer to the real hardware, which has a number of ways it can be configured to trigger sending the packet, some of which we don't implement.

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.
