commit 7544e597 upstream. This patch fixes a se_cmd->cmd_kref leak buf when se_sess->sess_tearing_down is true within target_get_sess_cmd() submission path code. This se_cmd reference leak can occur during active session shutdown when ack_kref=1 is passed by target_submit_cmd_[map_sgls,tmr]() callers. Signed-off-by:

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 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 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 cc261738 upstream. The commit [ef403edb: ALSA: hda - Don't access stereo amps for mono channel widgets] fixed the handling of mono widgets in general, but it still misses an exceptional case: namely, a mono mixer widget taking a single stereo input. In this case, it has stereo volumes although it's a mono widget, and thus we have to take care of both left and right input channels, as stated in HD-audio spec ("7.1.3 Widget Interconnection Rules"). This patch covers this missing piece by adding proper checks of stereo amps in both the generic parser and the proc output codes. Reported-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 0f611d28 upstream. Since moving the interface combination checks to mac80211, it's broken because it now only considers interfaces with an assigned channel context, so for example any interface that isn't active can still be up, which is clearly an issue; also, in particular P2P-Device wdevs are an issue since they never have a chanctx. Fix this by counting running interfaces instead the ones with a channel context assigned.

commit a9dc960c upstream. A number of tx queue wake-up events went missing due to the outlined scenario below. Start state is a pool of 16 tx URBs, active tx_urbs count = 15, with the netdev tx queue open. CPU #1 [softirq] CPU #2 [softirq] start_xmit() tx_acknowledge() ................ ................ atomic_inc(&tx_urbs); if (atomic_read(&tx_urbs) >= 16) { --> atomic_dec(&tx_urbs); netif_wake_queue(); return; <-- netif_stop_queue(); } At the end, the correct state expected is a 15 tx_urbs count value with the tx queue state _open_. Due to the race, we get the same tx_urbs value but with the tx queue state _stopped_. The wake-up event is completely lost. Thus avoid hand-rolled concurrency mechanisms and use a proper lock for contexts and tx queue protection. Signed-off-by:

commit 43b68879 upstream. As stated in kernel/cpu_pm.c, "Platform is responsible for ensuring that cpu_pm_enter is not called twice on the same CPU before cpu_pm_exit is called.". In the current code in case of failure when calling mvebu_v7_cpu_suspend, the function cpu_pm_exit() is never called whereas cpu_pm_enter() was called just before. This patch moves the cpu_pm_exit() in order to balance the cpu_pm_enter() calls. Reported-by:

commit f4c36863 upstream. drop_fpu() does clear_used_math() and usually this is correct because tsk == current. However switch_fpu_finish()->restore_fpu_checking() is called before __switch_to() updates the "current_task" variable. If it fails, we will wrongly clear the PF_USED_MATH flag of the previous task. So use clear_stopped_child_used_math() instead. Signed-off-by:

commit a7c80ebc upstream. math_state_restore() assumes it is called with irqs disabled, but this is not true if the caller is __restore_xstate_sig(). This means that if ia32_fxstate == T and __copy_from_user() fails, __restore_xstate_sig() returns with irqs disabled too. This triggers: BUG: sleeping function called from invalid context at kernel/locking/rwsem.c:41 dump_stack ___might_sleep ? _raw_spin_unlock_irqrestore __might_sleep down_read ? _raw_spin_unlock_irqrestore print_vma_addr signal_fault sys32_rt_sigreturn Change __restore_xstate_sig() to call set_used_math() unconditionally. This avoids enabling and disabling interrupts in math_state_restore(). If copy_from_user() fails, we can simply do fpu_finit() by hand. [ Note: this is only the first step. math_state_restore() should not check used_math(), it should set this flag. While init_fpu() should simply die. ] 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 ccfe8c3f upstream. The kernel crypto API logic requires the caller to provide the length of (ciphertext || authentication tag) as cryptlen for the AEAD decryption operation. Thus, the cipher implementation must calculate the size of the plaintext output itself and cannot simply use cryptlen. The RFC4106 GCM decryption operation tries to overwrite cryptlen memory in req->dst. As the destination buffer for decryption only needs to hold the plaintext memory but cryptlen references the input buffer holding (ciphertext || authentication tag), the assumption of the destination buffer length in RFC4106 GCM operation leads to a too large size. This patch simply uses the already calculated plaintext size. In addition, this patch fixes the offset calculation of the AAD buffer pointer: as mentioned before, cryptlen already includes the size of the tag. Thus, the tag does not need to be added. With the addition, the AAD will be written beyond the already allocated buffer. Note, this fixes a kernel crash that can be triggered from user space via AF_ALG(aead) -- simply use the libkcapi test application from [1] and update it to use rfc4106-gcm-aes. Using [1], the changes were tested using CAVS vectors to demonstrate that the crypto operation still delivers the right results.

Actually, the touchpads reports 3 extra buttons, which falls in the switch below to the '2' case. Let's handle the case of odd numbers also, so that the middle button finds its way back.

commit 02e07492 upstream. Post-2013 Lenovo laptops provide correct min/max dimensions, which are different with the ones currently quirked. According to https://bugzilla.kernel.org/show_bug.cgi?id=91541 the following board ids are assigned in the post-2013 touchpads: t440p/t440s: LEN0036 -> 2964/2962 t540p: LEN0034 -> 2964 Using 2961 as the common minimum makes these 3 laptops OK. We may need to update those values later if other pnp_ids has a lower board_id. Signed-off-by:

commit 5b3089dd upstream. Add a min/max range for board ids to the min/max coordinates quirk. This makes it possible to restrict quirks to specific models based upon their board id. The define ANY_BOARD_ID (0) serves as a wild card. Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=91541Signed-off-by:

commit b05f4d1c upstream. The firmware of the X240 (LEN0035, 2013/12) exposes the same values x [1232..5710], y [1156..4696] as the quirk applies. Signed-off-by:

commit ac097930 upstream. Query the min dimensions even if the check SYN_EXT_CAP_REQUESTS(priv->capabilities) >= 7 fails, but we know that the firmware version 8.1 is safe. With that we don't need quirks for post-2013 models anymore as they expose correct min and max dimensions. Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=91541Signed-off-by:
