commit d525211f upstream. Vince reported a watchdog lockup like: [<ffffffff8115e114>] perf_tp_event+0xc4/0x210 [<ffffffff810b4f8a>] perf_trace_lock+0x12a/0x160 [<ffffffff810b7f10>] lock_release+0x130/0x260 [<ffffffff816c7474>] _raw_spin_unlock_irqrestore+0x24/0x40 [<ffffffff8107bb4d>] do_send_sig_info+0x5d/0x80 [<ffffffff811f69df>] send_sigio_to_task+0x12f/0x1a0 [<ffffffff811f71ce>] send_sigio+0xae/0x100 [<ffffffff811f72b7>] kill_fasync+0x97/0xf0 [<ffffffff8115d0b4>] perf_event_wakeup+0xd4/0xf0 [<ffffffff8115d103>] perf_pending_event+0x33/0x60 [<ffffffff8114e3fc>] irq_work_run_list+0x4c/0x80 [<ffffffff8114e448>] irq_work_run+0x18/0x40 [<ffffffff810196af>] smp_trace_irq_work_interrupt+0x3f/0xc0 [<ffffffff816c99bd>] trace_irq_work_interrupt+0x6d/0x80 Which is caused by an irq_work generating new irq_work and therefore not allowing forward progress. This happens because processing the perf irq_work triggers another perf event (tracepoint stuff) which in turn generates an irq_work ad infinitum. Avoid this by raising the recursion counter in the irq_work -- which effectively disables all software events (including tracepoints) from actually triggering again. Reported-by:

commit d7c14605 upstream. The error code paths that require cleanup use a goto to jump to the cleanup code and return an error code. However, the error code variable res, which is initialized to -EINVAL when declared, is then overwritten with the return value of of_parse_phandle_with_args(), and reused as the return code from of_irq_parse_one(). This leads to an undetermined error being returned instead of the expected -EINVAL value. Fix it. Signed-off-by:

commit 2f1bce48 upstream. devm_phy_create() stores the pointer to the new PHY at the address returned by devres_alloc(). The res parameter passed to devm_phy_match() is therefore the location where the pointer to the PHY is stored, hence it needs to be dereferenced before comparing to the match data in order to find the correct match.

commit aa75ebc2 upstream. Some APs experience problems when working with U-APSD. Decreasing the probability of that happening by using legacy mode for all ACs but VO isn't enough. Cisco 4410N originally forced us to enable VO by default only because it treated non-VO ACs as legacy. However some APs (notably Netgear R7000) silently reclassify packets to different ACs. Since u-APSD ACs require trigger frames for frame retrieval clients would never see some frames (e.g. ARP responses) or would fetch them accidentally after a long time. It makes little sense to enable u-APSD queues by default because it needs userspace applications to be aware of it to actually take advantage of the possible additional powersavings. Implicitly depending on driver autotrigger frame support doesn't make much sense. Signed-off-by:

commit 496fcc29 upstream. As HT/VHT depend heavily on QoS/WMM, it's not a good idea to let userspace add clients that have HT/VHT but not QoS/WMM. Since it does so in certain cases we've observed (client is using HT IEs but not QoS/WMM) just ignore the HT/VHT info at this point and don't pass it down to the drivers which might unconditionally use it.

commit 75c3d0bf upstream. This patch fixes the incorrect use of __transport_register_session() in tcm_qla2xxx_check_initiator_node_acl() code, that does not perform explicit se_tpg->session_lock when accessing se_tpg->tpg_sess_list to add new se_sess nodes. Given that tcm_qla2xxx_check_initiator_node_acl() is not called with qla_hw->hardware_lock held for all accesses of ->tpg_sess_list, the code should be using transport_register_session() instead.

commit 7b8f10da upstream. The initialisation of the efm32 clocksource first sets up the irq and only after that initialises the data needed for irq handling. In case this initialisation is delayed the irq handler would dereference a NULL pointer. I'm not aware of anything that could delay the process in such a way, but it's better to be safe than sorry, so setup the irq only when the clock event device is ready. Acked-by:

commit 328f494d upstream. When inserting a new register into a block at the lower end the present bitmap is currently shifted into the wrong direction. The effect of this is that the bitmap becomes corrupted and registers which are present might be reported as not present and vice versa. Fix this by shifting left rather than right.

commit 1096be08 upstream. The interrupt is enabled before the handler is set. Even this bug did not appear, it is potentially dangerous as it can lead to a NULL pointer dereference. Fix the error by enabling the interrupt after clockevents_config_and_register() is called. Signed-off-by:

commit ae450e24 upstream. This patch changes core_scsi3_pro_release() logic to allow an existing AllRegistrants type reservation to be re-reserved by any registered I_T nexus. This addresses a issue where AllRegistrants type RESERVE was receiving RESERVATION_CONFLICT status if dev_pr_res_holder did not match the same I_T nexus, instead of just returning GOOD status following spc4r34 Section 5.9.9: "If the device server receives a PERSISTENT RESERVE OUT command with RESERVE service action where the TYPE field and the SCOPE field contain the same values as the existing type and scope from a persistent reservation holder, it shall not make any change to the existing persistent reservation and shall complete the command with GOOD status."

commit 6c3c9baa upstream. This patch fixes an issue with AllRegistrants reservations where an unregister operation by the I_T nexus reservation holder would incorrectly drop the reservation, instead of waiting until the last active I_T nexus is unregistered as per SPC-4. This includes updating __core_scsi3_complete_pro_release() to reset dev->dev_pr_res_holder with another pr_reg for this special case, as well as a new 'unreg' parameter to determine when the release is occuring from an implicit unregister, vs. explicit RELEASE. It also adds special handling in core_scsi3_free_pr_reg_from_nacl() to release the left-over pr_res_holder, now that pr_reg is deleted from pr_reg_list within __core_scsi3_complete_pro_release().

commit d16ca7c5 upstream. This patch fixes the usage of R_HOLDER bit for an All Registrants reservation in READ_FULL_STATUS, where only the registration who issued RESERVE was being reported as having an active reservation. It changes core_scsi3_pri_read_full_status() to check ahead of the list walk of active registrations to see if All Registrants is active, and if so set R_HOLDER bit and scope/type fields for all active registrations.

commit f068fbc8 upstream. This patch fixes a iser specific logout bug where early complete() of conn->conn_logout_comp in iscsit_close_connection() was causing isert_wait4logout() to complete too soon, triggering a use after free NULL pointer dereference of iscsi_conn memory. The complete() was originally added for traditional iscsi-target when a ISCSI_LOGOUT_OP failed in iscsi_target_rx_opcode(), but given iser-target does not wait in logout failure, this special case needs to be avoided.

commit 5f7da044 upstream. This patch fixes a NULL pointer dereference triggered by a late target_configure_device() -> alloc_workqueue() failure that results in target_free_device() being called with DF_CONFIGURED already set, which subsequently OOPses in destroy_workqueue() code. Currently this only happens at modprobe target_core_mod time when core_dev_setup_virtual_lun0() -> target_configure_device() fails, and the explicit target_free_device() gets called. To address this bug originally introduced by commit 0fd97ccf, go ahead and move DF_CONFIGURED to end of target_configure_device() code to handle this special failure case. Reported-by:

commit d2192ea0 upstream. Fixes: ee6c7507 (ARM: dts: dra7 clock data) On DRA7x, For DPLL_IVA, the ref clock(CLKINP) is connected to sys_clk1 and the bypass input(CLKINPULOW) is connected to iva_dpll_hs_clk_div clock. But the bypass input is not directly routed to bypass clkout instead both CLKINP and CLKINPULOW are connected to bypass clkout via a mux. This mux is controlled by the bit - CM_CLKSEL_DPLL_IVA[23]:DPLL_BYP_CLKSEL and it's POR value is zero which selects the CLKINP as bypass clkout. which means iva_dpll_hs_clk_div is not the bypass clock for dpll_iva_ck Fix this by adding another mux clock as parent in bypass mode. This design is common to most of the PLLs and the rest have only one bypass clock. Below is a list of the DPLLs that need this fix: DPLL_IVA, DPLL_DDR, DPLL_DSP, DPLL_EVE, DPLL_GMAC, DPLL_PER, DPLL_USB and DPLL_CORE Signed-off-by:
