2013-07-07vhost-net: fix use-after-free in vhost_net_flushMichael S. Tsirkin
vhost_net_ubuf_put_and_wait has a confusing name: it will actually also free it's argument. Thus since commit 1280c27f8e29acf4af2da914e80ec27c3dbd5c01 "vhost-net: flush outstanding DMAs on memory change" vhost_net_flush tries to use the argument after passing it to vhost_net_ubuf_put_and_wait, this results in use after free. To fix, don't free the argument in vhost_net_ubuf_put_and_wait, add an new API for callers that want to free ubufs.

2013-07-06iscsi-target: Fix ISCSI_OP_SCSI_TMFUNC handling for iserNicholas Bellinger
This patch adds target_get_sess_cmd reference counting for iscsit_handle_task_mgt_cmd(), and adds a target_put_sess_cmd() for the failure case. It also fixes a bug where ISCSI_OP_SCSI_TMFUNC type commands where leaking iscsi_cmd->i_conn_node and eventually triggering an OOPs during struct isert_conn shutdown.

2013-07-06iscsi-target: Fix iscsit_sequence_cmd reject handling for iserNicholas Bellinger
This patch moves ISCSI_OP_REJECT failures into iscsit_sequence_cmd() in order to avoid external iscsit_reject_cmd() reject usage for all PDU types. It also updates PDU specific handlers for traditional iscsi-target code to not reset the session after posting a ISCSI_OP_REJECT during setup.

2013-07-06iscsi-target: Fix iscsit_add_reject* usage for iserNicholas Bellinger
This patch changes iscsit_add_reject() + iscsit_add_reject_from_cmd() usage to not sleep on iscsi_cmd->reject_comp to address a free-after-use usage bug in v3.10 with iser-target code. It saves ->reject_reason for use within iscsit_build_reject() so the correct value for both transport cases. It also drops the legacy fail_conn parameter usage throughput iscsi-target code and adds two iscsit_add_reject_cmd() and iscsit_reject_cmd helper functions, along with various small cleanups. (v2: Re-enable target_put_sess_cmd() to be called from iscsit_add_reject_from_cmd() for rejects invoked after target_get_sess_cmd() has been called) Cc: Or Gerlitz <ogerlitz@mellanox.com> Cc: Mike Christie <michaelc@cs.wisc.edu> Cc: stable@vger.kernel.org # 3.10+ Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>

It also fixes ISTATE_SEND_REJECT handling in isert_response_completion() -> isert_do_control_comp() code, and drops incorrect iscsi_cmd_t->reject_comp usage.

2013-07-06Input: elantech - fix for newer hardware versions (v7)Matteo Delfino
* Fix version recognition in elantech_set_properties The new hardware reports itself as v7 but the packets' structure is unaltered. * Fix packet type recognition in elantech_packet_check_v4 The bitmask used for v6 is too wide, only the last three bits of the third byte in a packet (packet[3] & 0x03) are actually used to distinguish between packet types. Starting from v7, additional information (to be interpreted) is stored in the remaining bits (packets[3] & 0x1c). In addition, the value stored in (packet[0] & 0x0c) is no longer a constant but contains additional information yet to be deciphered. This change should be backwards compatible with v6 hardware.

2013-07-05drm/radeon: add support for 3d perf states on older asicsAlex Deucher
Certain older rv770 asics have both a performance and a 3D performance state rather than just multiple performance levels in the state power state. The current code would select the performance state rather than the 3D performance state when the "performance" profile was selected. This change switches to the "balanced" profile by default which ends up being the internal performance profile. When the user selects the "performance" profile, it selects the internal 3D performance state so the user can select the higher performance modes. For most asics this changes nothing. For certain rv770 asics with static performance and 3D performance states, this allows you to select between then using by selecting the "balanced" and "performance" dpm profiles.

The field containing the production date in the CID register only uses 4 bits to encode the year, starting from 1997 in the original standard. In 2013, the production year field contains 0, and the kernel reports a 1997 production date. The eMMC 4.51 specification adds a new interpretation rule. For all devices implementing the 4.41 specification or later, the production year field will be interpreted as a value between 2010 and 2025, with 0 corresponding to 2013.
