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).

2016-09-13rules.mak: Don't extract libs from .mo-libs in link commandFam Zheng
For module build, .mo objects are passed to LINK and consumed in process-archive-undefs. The reason behind that is documented in the comment above process-archive-undefs. Similarly, extract-libs should be called with .mo filtered out too. Otherwise, the .mo-libs are added to the link command incorrectly, spoiling the purpose of modularization. Currently we don't have any .mo-libs usage, but it will be used soon when we modularize more multi-source objects, like sdl and gtk.

2016-09-13tcg: cpu-exec: remove tb_lock from the hot-pathAlex Bennée
Lock contention in the hot path of moving between existing patched TranslationBlocks is the main drag in multithreaded performance. This patch pushes the tb_lock() usage down to the two places that really need it: - code generation (tb_gen_code) - jump patching (tb_add_jump) The rest of the code doesn't really need to hold a lock as it is either using per-CPU structures, atomically updated or designed to be used in concurrent read situations (qht_lookup). To keep things simple I removed the #ifdef CONFIG_USER_ONLY stuff as the locks become NOPs anyway until the MTTCG work is completed.

2016-09-13tcg: Prepare TB invalidation for lockless TB lookupPaolo Bonzini
When invalidating a translation block, set an invalid flag into the TranslationBlock structure first. It is also necessary to check whether the target TB is still valid after acquiring 'tb_lock' but before calling tb_add_jump() since TB lookup is to be performed out of 'tb_lock' in future. Note that we don't have to check 'last_tb'; an already invalidated TB will not be executed anyway and it is thus safe to patch it.

2016-09-13tcg: Prepare safe access to tb_flushed out of tb_lockSergey Fedorov
Ensure atomicity and ordering of CPU's 'tb_flushed' access for future translation block lookup out of 'tb_lock'. This field can only be touched from another thread by tb_flush() in user mode emulation. So the only access to be sequential atomic is: * a single write in tb_flush(); * reads/writes out of 'tb_lock'. In future, before enabling MTTCG in system mode, tb_flush() must be safe and this field becomes unnecessary.

2016-09-13ui/curses.c: Clean up nextchr logicPeter Maydell
Coverity identifies that at the top of the while(1) loop in curses_refresh() the variable nextchr is always ERR, and so the else case of the first if() is dead code. Remove this dead code, and narrow the scope of the nextchr variable to the place where it's used. (This confused logic has been present since the curses code was added to QEMU in 2008.)

2016-09-13ui/curses.c: Ensure we don't read off the end of curses2qemu arrayPeter Maydell
Coverity spots that there is no bounds check before we access the curses2qemu[] array. Add one, bringing this code path into line with the one that looks up entries in curses2keysym[]. In theory getch() shouldn't return out of range keycodes, but it's better not to assume this.

2016-09-13block/gluster: add support to choose libgfapi logfilePrasanna Kumar Kalever
currently all the libgfapi logs defaults to '/dev/stderr' as it was hardcoded in a call to glfs logging api. When the debug level is chosen to DEBUG/TRACE, gfapi logs will be huge and fill/overflow the console view. This patch provides a commandline option to mention log file path which helps in logging to the specified file and also help in persisting the gfapi logs. Usage: ----- *URI Style: --------- -drive file=gluster://hostname/volname/image.qcow2,file.debug=9,\ file.logfile=/var/log/qemu/qemu-gfapi.log *JSON Style: ---------- 'json:{ "driver":"qcow2", "file":{ "driver":"gluster", "volume":"volname", "path":"image.qcow2", "debug":"9", "logfile":"/var/log/qemu/qemu-gfapi.log", "server":[ { "type":"tcp", "host":"1.2.3.4", "port":24007 }, { "type":"unix", "socket":"/var/run/glusterd.socket" } ] } }' Reviewed-by: Jeff Cody <jcody@redhat.com> Reviewed-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Prasanna Kumar Kalever <prasanna.kalever@redhat.com> Signed-off-by: Jeff Cody <jcody@redhat.com>

2016-09-12crypto: report enum strings instead of values in errorsDaniel P. Berrange
Several error messages print out the raw enum value, which is less than helpful to users, as these values are not documented, nor stable across QEMU releases. Switch to use the enum string instead. The nettle impl also had two typos where it mistakenly said "algorithm" instead of "mode", and actually reported the algorithm value too.
