2015-03-16virtfs-proxy: Fix possible overflowShannon Zhao
It's detected by coverity. The socket name specified should fit in the sockadd_un.sun_path. If not abort. Signed-off-by: Shannon Zhao <zhaoshenglong@huawei.com> Signed-off-by: Shannon Zhao <shannon.zhao@linaro.org> Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
2015-03-129pfs-proxy: tiny cleanups in proxy_pwritev and proxy_preadvMichael Tokarev
Don't compare syscall return with -1, use "<0" condition. Don't introduce useless local variables when we already have similar variable Rename local variable to be consistent with other usages Finally make the two methods, read and write, to be similar to each other Signed-off-by: Michael Tokarev <mjt@tls.msk.ru> Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>

2014-11-02virtio-9p-proxy: fix error return in proxy_init()Michael Tokarev
proxy_init() does not check the return value of connect_namedsocket(), fix this by rearranging code a little bit. Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>
2014-11-02virtio-9p-proxy: Fix sockfd leakMichael Tokarev
If connect() in connect_namedsocket() return false, the sockfd will leak. Plug it. Signed-off-by: Michael Tokarev <mjt@tls.msk.ru> Signed-off-by: Gonglei <arei.gonglei@huawei.com>
2014-02-02hw/9pfs: make get_st_gen() return ENOTTY error on special filesKirill A. Shutemov
Currently we silently ignore getversion requests for anything except file or directory. Let's instead return ENOTTY error to indicate that getversion is not supported. It makes implementation consistent on all not-supported cases. Signed-off-by: Kirill A. Shutemov <kirill.shutemov@linux.intel.com> Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
2013-07-27hw/9pfs: Fix potential memory leak and avoid reuse of freed memoryStefan Weil
The leak was reported by cppcheck. Function proxy_init also calls g_free for ctx->fs_root. Avoid reuse of this memory by setting ctx->fs_root to NULL. Signed-off-by: Stefan Weil <sw@weilnetz.de> Reviewed-by: M. Mohan Kumar <mohan@in.ibm.com> Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>
2013-04-08hw: move headers to include/Paolo Bonzini
Many of these should be cleaned up with proper qdev-/QOM-ification. Right now there are many catch-all headers in include/hw/ARCH depending on cpu.h, and this makes it necessary to compile these files per-target. However, fixing this does not belong in these patches. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2013-03-01hw: move qdev-monitor.o to toplevel directoryPaolo Bonzini
qdev-monitor.c is the only "core qdev" file that is not used in user-mode emulation, and it does not define anything that is used by hardware models. Remove it from the hw/ directory and remove hw/qdev-monitor.h from hw/qdev.h too; this requires some files to have some new explicitly includes. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2012-01-06virtio-9p-proxy: Fix typo causing compile failure on 32 bit hostsPeter Maydell
Fix a compile failure on 32 bit hosts (integer constant is too large for 'unsigned long' type) by correcting a typo where the mask used for filling in the second f_fsid word had too many 'F's in it. Also drop the 'L' suffix that allowed this typo to go undetected on 64 bit hosts. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
