Hi guys. I seem to have found a bug in the helper_systet() function in
target-i386/seg_helper.c. I downloaded the Intel architecture manual from
here:
http://www.intel.c
Another interesting tidbit is in hw/9pfs/virtio-9p-proxy.c.
All filesystem methods use common v9fs_request() function,
which returns -errno. So far so good.
Now, *all* places which call this function, does this:
retval = v9fs_request(...);
if (retval < 0) {
errno = -retval;
I noticed that most file operations in hw/9pfs/virtio-9p-local.c
are modelled like this:
if (fs_ctx->export_flags & V9FS_SM_MAPPED) {
/* MAPPED version */
} else if (fs_ctx->export_flags & V9FS_SM_MAPPED_FILE) {
/* MAPPED_FILE version */
} else if ((fs_ctx->export_flags &
I was looking at various interesting functions in hw/9pfs/virtio-9p-local.c
and noticed local_open2() which basically tries to open a file in a
filesystem, and if that is successful, it tries to set file credentials
using a configured mechanism, and if that fails, it deletes the file.
Now I wonder

Omit one unnecessary memory allocation for components of the path

This uses (char*) cast because basename() accepts a char* without const,

The global parameter 'ram_size' does not take into account
the hotplugged memory.
In some codes, we use 'ram_size' as current VM's real RAM size,
which is not correct.
Add function 'get_current_ram_size' to calculate VM's current RAM size,
it will enumerate present memory de
