2016-11-01tcg: correct 32-bit tcg_gen_ld8s_i64 sign-extensionJoseph Myers
The version of tcg_gen_ld8s_i64 for 32-bit systems does a load into the low part of the return value - then attempts a sign extension into the high part, but wrongly sets the high part to a sign extension of itself rather than of the low part. This results in TCG internal errors from the use of the uninitialized high part (in some GCC tests of AArch64 NEON shift intrinsics, in particular). This patch corrects the sign-extension logic, making it match other functions such as tcg_gen_ld16s_i64.

2016-11-01tcg/tcg.h: Improve documentation of TCGv_i32 etc typesPeter Maydell
The typedefs we use for the TCGv_i32, TCGv_i64 and TCGv_ptr types are somewhat confusing, because we define them as pointers to structs, but the structs themselves are never defined. Explain in the comments a bit more clearly why this is OK and what is going on under the hood.

2016-11-01log: Add locking to large logging blocksRichard Henderson
Reuse the existing locking provided by stdio to keep in_asm, cpu, op, op_opt, op_ind, and out_asm as contiguous blocks. While it isn't possible to interleave e.g. in_asm or op_opt logs because of the TB lock protecting all code generation, it is possible to interleave cpu logs, or to interleave a cpu dump with an out_asm dump. For mingw32, we appear to have no viable solution for this. The locking functions are not properly exported from the system runtime library.

2016-11-01blockjobs: split interface into public/private, Part 1John Snow
To make it a little more obvious which functions are intended to be public interface and which are intended to be for use only by jobs themselves, split the interface into "public" and "private" files. Convert blockjobs (e.g. block/backup) to using the private interface. Leave blockdev and others on the public interface. There are remaining uses of private state by qemu-img, and several cases in blockdev.c and block/io.c where we grab job->blk for the purposes of acquiring an AIOContext. These will be corrected in future patches.

2016-11-01block/gluster: improve defense over string to int conversionPrasanna Kumar Kalever
using atoi() for converting string to int may be error prone in case if string supplied in the argument is not a fold of numerical number, This is not a bug because in the existing code, static QemuOptsList runtime_tcp_opts = { .name = "gluster_tcp", .head = QTAILQ_HEAD_INITIALIZER(runtime_tcp_opts.head), .desc = { ... { .name = GLUSTER_OPT_PORT, .type = QEMU_OPT_NUMBER, .help = "port number ...", }, ... }; port type is QEMU_OPT_NUMBER, before we actually reaches atoi() port is already defended by parse_option_number() However It is a good practice to use function like parse_uint_full() over atoi() to keep port self defended Note: As now the port string to int conversion has its defence code set, and also we understand that port argument is actually a string type, in the follow up patch let's move port type from QEMU_OPT_NUMBER to QEMU_OPT_STRING [Jeff Cody: removed spurious parenthesis] Signed-off-by: Prasanna Kumar Kalever <prasanna.kalever@redhat.com> Reviewed-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Jeff Cody <jcody@redhat.com>
2016-11-01block: Turn on "unmap" in active commitFam Zheng
We already specified BDRV_O_UNMAP when opening images in 'qemu-img commit', but didn't turn on the "unmap" in the active commit job. This patch fixes that so that zeroed clusters in top image can be discarded which is desired in the virt-sparsify use case, where a temporary overlay is created and fstrim'ed before commiting back, to free space in the original image. This also enables it for block-commit.

2016-11-01block/gluster: memory usage: use one glfs instance per volumePrasanna Kumar Kalever
Currently, for every drive accessed via gfapi we create a new glfs instance (call glfs_new() followed by glfs_init()) which could consume memory in few 100 MB's, from the table below it looks like for each instance ~300 MB VSZ was consumed Before: ------- Disks VSZ RSS 1 1098728 187756 2 1430808 198656 3 1764932 199704 4 2084728 202684 This patch maintains a list of pre-opened glfs objects. On adding a new drive belonging to the same gluster volume, we just reuse the existing glfs object by updating its refcount. With this approch we shrink up the unwanted memory consumption and glfs_new/glfs_init calls for accessing a disk (file) if belongs to same volume. From below table notice that the memory usage after adding a disk (which will reuse the existing glfs object hence) is in negligible compared to before.

2016-11-019pfs: fix integer overflow issue in xattr read/writeLi Qiang
The v9fs_xattr_read() and v9fs_xattr_write() are passed a guest originated offset: they must ensure this offset does not go beyond the size of the extended attribute that was set in v9fs_xattrcreate(). Unfortunately, the current code implement these checks with unsafe calculations on 32 and 64 bit values, which may allow a malicious guest to cause OOB access anyway. Fix this by comparing the offset and the xattr size, which are both uint64_t, before trying to compute the effective number of bytes to read or write.

2016-10-31sockets: add AF_VSOCK supportStefan Hajnoczi
Add the AF_VSOCK address family so that qemu-ga will be able to use virtio-vsock. The AF_VSOCK address family uses <cid, port> address tuples. The cid is the unique identifier comparable to an IP address. AF_VSOCK does not use name resolution so it's easy to convert between struct sockaddr_vm and strings. This patch defines a VsockSocketAddress instead of trying to piggy-back on InetSocketAddress. This is cleaner in the long run since it avoids lots of IPv4 vs IPv6 vs vsock special casing.

2016-10-31qga: drop unnecessary GA_CHANNEL_UNIX_LISTEN checksStefan Hajnoczi
Throughout the code there are c->listen_channel checks which manage the listen socket file descriptor (waiting for accept(2), closing the file descriptor, etc). These checks are currently preceded by explicit c->method == GA_CHANNEL_UNIX_LISTEN checks. Explicit GA_CHANNEL_UNIX_LISTEN checks are not necessary since serial channel types do not create the listen channel (c->listen_channel). As more listen channel types are added, explicitly checking all of them becomes messy. Rely on c->listen_channel to determine whether or not a listen socket file descriptor is used.

2016-10-31qga: drop unused sockaddr in accept(2) callStefan Hajnoczi
ga_channel_listen_accept() is currently hard-coded to support only AF_UNIX because the struct sockaddr_un type is used. This function should work with any address family. Drop the sockaddr since the client address is unused and is an optional argument to accept(2).

2016-10-31qga: minimal support for fstrim for Windows guestsDenis V. Lunev
Unfortunately, there is no public Windows API to start trimming the filesystem. The only viable way here is to call 'defrag.exe /L' for each volume. This is working since Win8 and Win2k12.

2016-10-31target-sparc: Allow 4-byte alignment on fp mem opsRichard Henderson
The cpu is allowed to require stricter alignment on these 8- and 16-byte operations, and the OS is required to fix up the accesses as necessary, so the previous code was not wrong. However, we can easily handle this misalignment for all direct 8-byte operations and for direct 16-byte loads. We must retain 16-byte alignment for 16-byte stores, so that we don't have to probe for writability of a second page before performing the first of two 8-byte stores. We also retain 8-byte alignment for no-fault loads, since they are rare and it's not worth extending the helpers for this.
