2016-09-13optionrom: do not rely on compiler's bswap optimizationPaolo Bonzini
Recent compilers can detect and inline manually-written bswap code, but GCC 4.2.1 (the last GPLv2 version) cannot and generates really awful code. Depending on how the compiler is configured, it might also not want to generate bswap because it was not in i386. Using asm is fine because TCG knows about bswap and all processors with virtualization extensions also do.

The mux chardev was not checking the return value of any qemu_chr_fe_write() call so would silently loose data on EAGAIN. Similarly the qemu_chr_fe_printf method would not check errors and was not in a position to retry even if it could check. Signed-off-by: Daniel P.

2016-09-13hw: replace most use of qemu_chr_fe_write with qemu_chr_fe_write_allDaniel P. Berrange
The qemu_chr_fe_write method will return -1 on EAGAIN if the chardev backend write would block. Almost no callers of the qemu_chr_fe_write() method check the return value, instead blindly assuming data was successfully sent. In most cases this will lead to silent data loss on interactive consoles, but in some cases (eg RNG EGD) it'll just cause corruption of the protocol being spoken. We unfortunately can't fix the virtio-console code, due to a bug in the Linux guest drivers, which would cause the entire Linux kernel to hang if we delay processing of the incoming data in any way. Fixing this requires first fixing the guest driver to not hold spinlocks while writing to the hvc device backend. Fixes bug: https://bugs.launchpad.net/qemu/+bug/1586756 Signed-off-by: Daniel P.

2016-09-13sclpconsolelm: remove bogus check for -EAGAINDaniel P. Berrange
The write_console_data() method in sclpconsole-lm.c checks whether the return value of qemu_chr_fe_write() has the value of -EAGAIN and if so then increments the buffer offset by the value of EAGAIN. Fortunately qemu_chr_fe_write() will never return EAGAIN directly, rather it returns -1 with errno set to EAGAIN, so this broken code path was not reachable. The behaviour on EAGAIN was stil bad though, causing the write_console_data() to busy_wait repeatedly calling qemu_chr_fe_write() with no sleep between iters. Just remove all this loop logic and replace with a call to qemu_chr_fe_write_all(). Acked-by: Cornelia Huck <cornelia.huck@de.ibm.com> Signed-off-by: Daniel P.

2016-09-13ipmi: check return of qemu_chr_fe_write() for errorsDaniel P. Berrange
The continue_send() method in ipmi_bmc_extern.c directly assigns the return value of qemu_chr_fe_write() to the variable tracking the I/O buffer offset. This ignores the possibility that the return value could be -1 and so will cause I/O go backwards on EAGAIN. Fortunately 'outpos' is unsigned, so can't go negative - it will become MAX_INT which will cause the loop to stop, and avoid an accidental out of bounds array access. Signed-off-by: Daniel P.

2016-09-13scsi: pvscsi: limit loop to fetch SG listPrasad J Pandit
In PVSCSI paravirtual SCSI bus, pvscsi_convert_sglist can take a very long time or go into an infinite loop due to two different bugs: 1) the request descriptor data length is defined to be 64 bit. While building SG list from a request descriptor, it gets truncated to 32bit in routine 'pvscsi_convert_sglist'. This could lead to an infinite loop situation large 'dataLen' values when data_length is cast to uint32_t and chunk_size becomes always zero. Fix this by removing the incorrect cast. 2) pvscsi_get_next_sg_elem can be called arbitrarily many times if the element has a zero length. Get out of the loop early when this happens, by introducing an upper limit on the number of SG list elements.

2016-09-13scsi-disk: change disk serial length from 20 to 36Rony Weng
Openstack Cinder assigns volume a 36 characters uuid as serial. QEMU will shrinks the uuid to 20 characters, which does not match the original uuid. Note that there is no limit to the length of the serial number in the SCSI spec. 20 was copy-pasted from virtio-blk which in turn was copy-pasted from ATA; 36 is even more arbitrary. However, bumping it up too much might cause issues (e.g. 252 seems to make sense because then the maximum amount of returned data is 256; but who knows there's no off-by-one somewhere for such a nicely rounded number).

2016-09-13lsi: never set DMA FIFO Empty (DFE) bit in DSTAT registerHervé Poussineau
53C895A datasheet says: "This bit (DFE) is a pure status bit and will not cause an interrupt" This bit is already auto-generated in lsi_read_reg when reading the DSTAT register. This fixes IBM RS/6000 7020 firmware, which is: - resetting the adapter - enabling all interrupt sources (including DIP, ie interrupts from DSTAT) - waiting for ISTAT0 to become 0 (including DIP=0, ie no interrupt coming from DSTAT) Signed-off-by: Hervé Poussineau <hpoussin@reactos.org> Message-Id: <1471505489-1221-5-git-send-email-hpoussin@reactos.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Hervé Poussineau <hpoussin@reactos.org>
