2014-03-04hw/9pfs: use g_strdup_printf() instead of PATH_MAX limitationChen Gang
When path is truncated by PATH_MAX limitation, it causes QEMU to access incorrect file. So use original full path instead of PATH_MAX within 9pfs (need check/process ENOMEM for related memory allocation). The related test: - Environments (for qemu-devel): - Host is under fedora17 desktop with ext4fs: qemu-system-x86_64 -hda test.img -m 1024 \ -net nic,vlan=4,model=virtio,macaddr=00:16:35:AF:94:04 \ -net tap,vlan=4,ifname=tap4,script=no,downscript=no \ -device virtio-9p-pci,id=fs0,fsdev=fsdev0,mount_tag=hostshare \ -fsdev local,security_model=passthrough,id=fsdev0,\ path=/upstream/vm/data/share/1234567890abcdefghijklmnopqrstuvwxyz\ ABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890acdefghijklmnopqrstuvwxyz\ ABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890/111111111111111111111111111\ 1111111111111111111111111111111111111111111111111111222222222222\ 2222222222222222222222222222222222222222222222222222222222222222\ 2222222222222222222222222222222222233333333333333333333333333333\ 3333333333333333333333333333333333 -

2014-02-02hw/9pfs: fix P9_STATS_GEN handlingKirill A. Shutemov
Currently we fail getattr request altogether if we can't read P9_STATS_GEN for some reason. It breaks valid use cases: E.g let's assume we have non-readable directory with execution bit set on host and we export it to client over 9p On host we can chdir into directory, but not open directory on read and list content. But if client will try to call getattr (as part of chdir(2)) for the directory it will fail with -EACCES. It happens because we try to open the directory on read to call ioctl(FS_IOC_GETVERSION), it fails and we return the error code to client. It's excessive. The solution is to make P9_STATS_GEN failure non-fatal for getattr request. Just don't set P9_STATS_GEN flag in result mask on failure. Signed-off-by: Kirill A.

2013-10-05hw/9pfs: Fix errno value for xattr functionsDaniel P. Berrange
If there is no operation driver for the xattr type the functions return '-1' and set errno to '-EOPNOTSUPP'. When the calling code sets 'ret = -errno' this turns into a large positive number. In Linux 3.11, the kernel has switched to using 9p version 9p2000.L, instead of 9p2000.u, which enables support for xattr operations. This on its own is harmless, but for another change which makes it request the xattr with a name 'security.capability'. The result is that the guest sees a succesful return of 95 bytes of data, instead of a failure with errno set to 95. Since the kernel expects a maximum of 20 bytes for an xattr return this gets translated to the unexpected errno ERANGE. This all means that when running a binary off a 9p fs in 3.11 kernels you get a fun result of: # ./date sh: ./date: Numerical result out of range The only workaround is to pass 'version=9p2000.u' when mounting the 9p fs in the guest, to disable all use of xattrs.

2013-05-28hw/9pfs: Be robust against paths without FS_IOC_GETVERSIONGabriel de Perthuis
9P optionally uses the FS_IOC_GETVERSION ioctl to get information about a file's version (sometimes called generation number). The code checks for supported filesystems at mount time, but some paths may come from other mounted filesystems. Change it to treat unsupported paths the same as unsupported filesystems, returning 0 in both cases. Note: ENOTTY is the error code for an unsupported ioctl. This fix allows booting a linux kernel with the same / filesystem as the host; otherwise the boot fails when mounting devtmpfs.

2013-01-30g_malloc(0) and g_malloc0(0) return NULL; simplifyMarkus Armbruster
Once upon a time, it was decided that qemu_malloc(0) should abort. Switching to glib retired that bright idea. Some code that was added to cope with it (e.g. in commits 702ef63, b76b6e9) is still around. Bury it.

2013-01-10Make all static TypeInfos constAndreas Färber
Since 39bffca2030950ef6efe57c2fac8327a45ae1015 (qdev: register all types natively through QEMU Object Model), TypeInfo as used in the common, non-iterative pattern is no longer amended with information and should therefore be const. Fix the documented QOM examples: sed -i 's/static TypeInfo/static const TypeInfo/g' include/qom/object.h Since frequently the wrong examples are being copied by contributors of new devices, fix all types in the tree: sed -i 's/^static TypeInfo/static const TypeInfo/g' */*.c sed -i 's/^static TypeInfo/static const TypeInfo/g' */*/*.c This also avoids to piggy-back these changes onto real functional changes or other refactorings.

2012-10-05virtio-9p: avoid unwarranted uses of strncpyJim Meyering
In all of these cases, the uses of strncpy were unnecessary, since at each point of use we know that the NUL-terminated source bytes fit in the destination buffer. Use memcpy in place of strncpy.
