10 years agoqom: Clean up fragile use of error_is_set() in set() methods
Markus Armbruster [Fri, 25 Apr 2014 10:44:22 +0000 (12:44 +0200)]
qom: Clean up fragile use of error_is_set() in set() methods

Using error_is_set(ERRP) to find out whether a function failed is
either wrong, fragile, or unnecessarily opaque.  It's wrong when ERRP
may be null, because errors go undetected when it is.  It's fragile
when proving ERRP non-null involves a non-local argument.  Else, it's
unnecessarily opaque (see commit 84d18f0).

I guess the error_is_set(errp) in the ObjectProperty set() methods are
merely fragile right now, because I can't find a call chain that
passes a null errp argument.

Make the code more robust and more obviously correct: receive the
error in a local variable, then propagate it through the parameter.

curl: Eliminate unnecessary use of curl_multi_socket_all

curl_multi_socket_all is a deprecated catch-all which checks for
activities on all open curl sockets. We have enough information from
the event loop to check only the sockets with activity. This change
removes use of curl_multi_socket_all in favour of
curl_multi_socket_action called with the relevant handle.

At the same time, it also ensures that the driver only checks for
completion of read operations after reading from a socket, rather than
both reading and writing.

Currently, seek_to_sector() returns -1 both for errors and unallocated

clusters (bitmap_offset is greater than 0 because s->data_offset is

That function also has a case of "return -1 in case of error", which is
fixed by this patch as well.

bochs_read() is called by bochs_co_read() which passes the return value

Max Reitz [Tue, 29 Apr 2014 17:03:14 +0000 (19:03 +0200)]
qcow2: Check min_size in qcow2_grow_l1_table()

First, new_l1_size is an int64_t, whereas min_size is a uint64_t.
Therefore, during the loop which adjusts new_l1_size until it equals or
exceeds min_size, new_l1_size might overflow and become negative. The
comparison in the loop condition however will take it as an unsigned
value (because min_size is unsigned) and therefore recognize it as
exceeding min_size. Therefore, the loop is left with a negative
new_l1_size, which is not correct. This could be fixed by making
new_l1_size uint64_t.

On the other hand, however, by doing this, the while loop may take
forever. If min_size is e.g. UINT64_MAX, it will take new_l1_size
probably multiple overflows to reach the exact same value (if it reaches
it at all). Then, right after the loop, new_l1_size will be recognized
as being too big anyway.

Both problems require a ridiculously high min_size value, which is very
unlikely to occur; but both problems are also simply avoided by checking
whether min_size is sane before calculating new_l1_size (which should
still be checked separately, though).

Revert "block: another bdrv_append fix"

This reverts commit 3a389e7926750cba5c83f662b1941888b2bebc04. The commit
was wrong and what it tried to fix just works today without any change.

What the commit tried to fix:

    When creating live snapshots, the new image file is opened with
    BDRV_O_NO_BACKING because the whole backing chain is already opened.
    It is then appended to the chain using bdrv_append(). The result of
    this was that the image had a backing file, but BDRV_O_NO_BACKING
    was still set. This is obviously inconsistent.

    There used to be some places in qemu that closed and image and then
    opened it again, with its old flags (a bdrv_open()/close() sequence
    involves reopening the whole backing file chain, too). In this case
    the BDRV_O_NO_BACKING flag meant that the backing chain wasn't
    reopened and only the top layer was left.

    (Most, but not all of these places are replaced by bdrv_reopen()
    today, which doesn't touch the backing files at all.)

    Other places that looked at bs->open_flags weren't interested in
    BDRV_O_NO_BACKING, so no breakage there.

What it actually did:

    The commit moved the BDRV_O_NO_BACKING away to the backing file.
    Because the bdrv_open()/close() sequences only looked at the flags
    of the top level BlockDriverState and used it for the whole chain,
    the flag didn't hurt there any more. Obviously, it is still
    inconsistent because the backing file may have another backing file,
    but without practical impact.

    At the same time, it swapped all other flags. This is practically
    irrelevant as long as live snapshots only allow opening the new
    layer with the same flags as the old top layer. It still doesn't
    make any sense, and it is a time bomb that explodes as soon as the
    flags can differ.

    bdrv_append_temp_snapshot() is such a case: It adds the new flag
    BDRV_O_TEMPORARY for the temporary snapshot. The swapping of commit
    3a389e79 results in the following nonsensical configuration:

    bs->open_flags:                     BDRV_O_TEMPORARY cleared
    bs->file->open_flags:               BDRV_O_TEMPORARY set
    bs->backing_hd->open_flags:         BDRV_O_TEMPORARY set
    bs->backing_hd->file->open_flags:   BDRV_O_TEMPORARY cleared

    We're still lucky because the format layer ignores the flag and the
    protocol layer happens to get the right value, but sooner or later
    this is bound to go wrong...

What the right fix would have been:

    Simply clear the BDRV_O_NO_BACKING flag when the BlockDriverState is
    appended to an existing backing file chain, because now it does have
    a backing file.

    Commit 4ddc07ca already implemented this silently in bdrv_append(),
    so we don't have to come up with a new fix.

block: Ignore duplicate or NULL format_name in bdrv_iterate_format

Some block drivers have multiple BlockDriver instances with identical
format_name fields (e.g. gluster, nbd).

Both qemu-img and qemu will use bdrv_iterate_format() to list the
supported formats when a help option is invoked.  As protocols and
formats may register multiple drivers, redundant listings of formats
occur (e.g., "Supported formats: ... gluster gluster gluster gluster ...
").

Since the list of driver formats will be small, this performs a simple
linear search on format_name, and ignores any duplicates.

The end result change is that the iterator will no longer receive
duplicate string names, nor will it receive NULL pointers.

vga: add secondary stdvga variant

Add a standard vga variant which doesn't occupy any legacy
resources and thus can easily be used as secondary (or legacy-free)
graphics adapter.  Programming must be done using the MMIO bar.

secondary vga cards.  Add a bool parameter to vga_common_init

slirp/smb: Move ncalrpc directory to tmp

The smbd forked by qemu still uses the default ncalrpc directory
in /var/run/samba. This may lead to problems, if /var/run/samba
does not exist (for example if /var/run is a tmpfs and the host
smbd was not started).

This leads to the following error message from samba
and an unworkable smbd:
Failed to create pipe directory /var/run/samba/ncalrpc - No such file or directory

Fix this by pointing smbd to /tmp/qemu-smb.%d.%d/ncalrpc as ncalrpc directory.
Smbd will create the actual ncalrpc subdirectory on its own.
