When processing a MCE_RSP_GETPORTSTATUS command, the bit index to set in ir->txports_cabled comes from response data, and isn't validated. As ir->txports_cabled is a u8, nothing should be done if the bit index is greater than 7. Cc: stable@vger.kernel.org Reported-by: syzbot+ec3b3128c576e109171d@syzkaller.appspotmail.com Signed-off-by:

The hfi_session_init can be called many times and it returns EINVAL when the session was already initialized. This error code (EINVAL) is confusing for the callers. Change hfi_session_init to return EALREADY error code when the session has been already initialized. Tested-by:

Currently we rely on firmware to return error when we reach the maximum supported number of sessions. But this errors are happened at reqbuf time which is a bit later. The more reasonable way looks like is to return the error on driver open. To achieve that modify hfi_session_create to return error when we reach maximum count of sessions and thus refuse open.

If the DRC is near the end of the stream the client may send a V4L2_DEC_CMD_STOP before the DRC occurs. V4L2_DEC_CMD_STOP puts the driver into the VENUS_DEC_STATE_DRAIN state. DRC must be aware so that after the DRC event the state can be restored correctly. Signed-off-by:

DRC events can happen virtually at anytime, including when we are starting a seek. Should this happen, we must make sure to return to the DRC state, otherwise the firmware will expect buffers of the new resolution whereas userspace will still work with the old one. Returning to the DRC state upon resume for seeking makes sure that the client will get the DRC event and will reallocate the buffers to fit the firmware's expectations. Signed-off-by:

After adding more logic in vdec buf_queue vb2 op it is not practical to have two lock/unlock for one decoder buf_queue. So move the instance lock in encoder and decoder vb2 buf_queue operations. Signed-off-by:

This makes the decoder to behaives equally for sufficient and insufficient events. After this change the LAST buffer flag will be set when the new resolution (in dynamic-resolution-change state) is smaller then the old bitstream resolution. Signed-off-by:
-
Stanimir Varbanov authored
In real use of dynamic-resolution-change it is observed that the LAST buffer flag (which marks the last decoded buffer with the resolution before the resolution-change event) is not reliably set. Fix this by set the LAST buffer flag on next queued capture buffer after the resolution-change event. Signed-off-by:

This driver uses the SG vb2 ops, but effectively only ever accesses the first entry of the SG table, indicating that it expects a flat layout. Switch it to use the contiguous ops to make sure this expected invariant is always enforced. Since the device is supposed to be behind an IOMMU this should have little to none practical consequences beyond making the driver not rely on a particular behavior of the SG implementation.
