2016-10-179pfs: use coroutine_fn annotation in hw/9pfs/co*.[ch]Greg Kurz1-18/+25
All these functions use the v9fs_co_run_in_worker() macro, and thus always call qemu_coroutine_self() and qemu_coroutine_yield(). Let's mark them to make it obvious they execute in coroutine context. Signed-off-by: Greg Kurz <groug@kaod.org>
2016-06-069p/fsdev: remove obsolete references to virtioGreg Kurz1-2/+1
Most of the 9p code is now virtio agnostic. This patch does a final cleanup: - drop references to Virtio from the header comments - fix includes Also drop a couple of leading empty lines while here. Signed-off-by: Greg Kurz <gkurz@linux.vnet.ibm.com>
2016-01-299pfs: Clean up includesPeter Maydell1-0/+1
Clean up includes so that osdep.h is included first and headers which it implies are not included manually. This commit was created with scripts/clean-includes. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Message-id: 1453832250-766-18-git-send-email-peter.maydell@linaro.org
2016-01-089pfs: rename virtio-9p-coth.{c,h} to coth.{c,h}Wei Liu1-1/+1
Those two files are not virtio specific. Rename them to use generic names. Fix includes in various C files. Change define guards and comments in header files. Signed-off-by: Wei Liu <wei.liu2@citrix.com> Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
2015-10-20coroutine: move into libqemuutil.a libraryDaniel P. Berrange1-1/+1
The coroutine files are currently referenced by the block-obj-y variable. The coroutine functionality though is already used by more than just the block code. eg migration code uses coroutine yield. In the future the I/O channel code will also use the coroutine yield functionality. Since the coroutine code is nicely self-contained it can be easily built as part of the libqemuutil.a library, making it widely available. The headers are also moved into include/qemu, instead of the include/block directory, since they are now part of the util codebase, and the impl was never in the block/ directory either.

2014-03-04hw/9pfs: use g_strdup_printf() instead of PATH_MAX limitationChen Gang1-14/+34
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 -

"mkdir -p", "create/open file/dir", "modify file/dir", "rm file/dir". change various mount point paths under host and/or guest.
