2017-05-259pfs: assume utimensat() and futimens() are presentGreg Kurz1-5/+0
The utimensat() and futimens() syscalls have been around for ages (ie, glibc 2.6 and linux 2.6.22), and the decision was already taken to switch to utimensat() anyway when fixing CVE-2016-9602 in 2.9. Signed-off-by: Greg Kurz <groug@kaod.org> Reviewed-by: Eric Blake <eblake@redhat.com>
2016-11-239pfs: add cleanup operation for handle backend driverLi Qiang1-0/+9
In the init operation of handle backend dirver, it allocates a handle_data struct and opens a mount file. We should free these resources when the 9pfs device is unrealized. This is what this patch does. Signed-off-by: Li Qiang <liq3ea@gmail.com> Reviewed-by: Greg Kurz <groug@kaod.org> Signed-off-by: Greg Kurz <groug@kaod.org>
2016-06-069p: switch back to readdir()Greg Kurz1-5/+3
This patch changes the 9p code to use readdir() again instead of readdir_r(), which is deprecated in glibc 2.24. All the locking was put in place by a previous patch. Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Greg Kurz <gkurz@linux.vnet.ibm.com>
2016-06-069p: introduce the V9fsDir typeGreg Kurz1-9/+9
If we are to switch back to readdir(), we need a more complex type than DIR * to be able to serialize concurrent accesses to the directory stream. This patch introduces a placeholder type and fixes all users. Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Greg Kurz <gkurz@linux.vnet.ibm.com>
2016-03-22util: move declarations out of qemu-common.hVeronia Bahaa1-0/+1
Move declarations out of qemu-common.h for functions declared in utils/ files: e.g. include/qemu/path.h for utils/path.c. Move inline functions out of qemu-common.h and into new files (e.g. include/qemu/bcd.h) Signed-off-by: Veronia Bahaa <veroniabahaa@gmail.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

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
