-Subject: [PATCH] ui/clipboard: mark type as not available when there is no
- data
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-With VNC, a client can send a non-extended VNC_MSG_CLIENT_CUT_TEXT
-message with len=0. In qemu_clipboard_set_data(), the clipboard info
-will be updated setting data to NULL (because g_memdup(data, size)
-returns NULL when size is 0). If the client does not set the
-VNC_ENCODING_CLIPBOARD_EXT feature when setting up the encodings, then
-the 'request' callback for the clipboard peer is not initialized.
-Later, because data is NULL, qemu_clipboard_request() can be reached
-via vdagent_chr_write() and vdagent_clipboard_recv_request() and
-there, the clipboard owner's 'request' callback will be attempted to
-be called, but that is a NULL pointer.
-
-In particular, this can happen when using the KRDC (22.12.3) VNC
-client.
-
-Another scenario leading to the same issue is with two clients (say
-noVNC and KRDC):
-
-The noVNC client sets the extension VNC_FEATURE_CLIPBOARD_EXT and
-initializes its cbpeer.
-
-The KRDC client does not, but triggers a vnc_client_cut_text() (note
-it's not the _ext variant)). There, a new clipboard info with it as
-the 'owner' is created and via qemu_clipboard_set_data() is called,
-which in turn calls qemu_clipboard_update() with that info.
-
-In qemu_clipboard_update(), the notifier for the noVNC client will be
-called, i.e. vnc_clipboard_notify() and also set vs->cbinfo for the
-noVNC client. The 'owner' in that clipboard info is the clipboard peer
-for the KRDC client, which did not initialize the 'request' function.
-That sounds correct to me, it is the owner of that clipboard info.
-
-Then when noVNC sends a VNC_MSG_CLIENT_CUT_TEXT message (it did set
-the VNC_FEATURE_CLIPBOARD_EXT feature correctly, so a check for it
-passes), that clipboard info is passed to qemu_clipboard_request() and
-the original segfault still happens.
-
-Fix the issue by handling updates with size 0 differently. In
-particular, mark in the clipboard info that the type is not available.
-
-While at it, switch to g_memdup2(), because g_memdup() is deprecated.
