2019-08-22ipmi: move message error checking to avoid deadlockTony Camuso
V1->V2: in handle_one_rcv_msg, if data_size > 2, set requeue to zero and goto out instead of calling ipmi_free_msg. Kosuke Tatsukawa <tatsu@ab.jp.nec.com> In the source stack trace below, function set_need_watch tries to take out the same si_lock that was taken earlier by ipmi_thread. ipmi_thread() [drivers/char/ipmi/ipmi_si_intf.c:995] smi_event_handler() [drivers/char/ipmi/ipmi_si_intf.c:765] handle_transaction_done() [drivers/char/ipmi/ipmi_si_intf.c:555] deliver_recv_msg() [drivers/char/ipmi/ipmi_si_intf.c:283] ipmi_smi_msg_received() [drivers/char/ipmi/ipmi_msghandler.c:4503] intf_err_seq() [drivers/char/ipmi/ipmi_msghandler.c:1149] smi_remove_watch() [drivers/char/ipmi/ipmi_msghandler.c:999] set_need_watch() [drivers/char/ipmi/ipmi_si_intf.c:1066] Upstream commit e1891cffd4c4896a899337a243273f0e23c028df adds code to ipmi_smi_msg_received() to call smi_remove_watch() via intf_err_seq() and this seems to be causing the deadlock. commit e1891cffd4c4896a899337a243273f0e23c028df Author: Corey Minyard <cminyard@mvista.com> Date: Wed Oct 24 15:17:04 2018 -0500 ipmi: Make the smi watcher be disabled immediately when not needed The fix is to put all messages in the queue and move the message checking code out of ipmi_smi_msg_received and into handle_one_recv_msg, which processes the message checking after ipmi_thread releases its locks. Additionally,Kosuke Tatsukawa <tatsu@ab.jp.nec.com> reported that handle_new_recv_msgs calls ipmi_free_msg when handle_one_rcv_msg returns zero, so that the call to ipmi_free_msg in handle_one_rcv_msg introduced another panic when "ipmitool sensor list" was run in a loop. He submitted this part of the patch. +free_msg: + requeue = 0; + goto out; Reported by: Osamu Samukawa <osa-samukawa@tg.jp.nec.com> Characterized by: Kosuke Tatsukawa <tatsu@ab.jp.nec.com> Signed-off-by: Tony Camuso <tcamuso@redhat.com> Fixes: e1891cffd4c4 ("ipmi: Make the smi watcher be disabled immediately when not needed") Cc: stable@vger.kernel.org # 5.1 Signed-off-by: Corey Minyard <cminyard@mvista.com>
2019-08-22ipmi_ssif: avoid registering duplicate ssif interfaceKamlakant Patel
It is possible that SSIF interface entry is present in both DMI and ACPI tables. In SMP systems, in such cases it is possible that ssif_probe could be called simultaneously from i2c interface (from ACPI) and from DMI on different CPUs at kernel boot. Both try to register same SSIF interface simultaneously and result in race. In such cases where ACPI and SMBIOS both IPMI entries are available, we need to prefer ACPI over SMBIOS so that ACPI functions work properly if they use IPMI. So, if we get an ACPI interface and have already registered an SMBIOS at the same address, we need to remove the SMBIOS one and add the ACPI. Log: [ 38.774743] ipmi device interface [ 38.805006] ipmi_ssif: IPMI SSIF Interface driver [ 38.861979] ipmi_ssif i2c-IPI0001:06: ssif_probe CPU 99 *** [ 38.863655] ipmi_ssif 0-000e: ssif_probe CPU 14 *** [ 38.863658] ipmi_ssif: Trying SMBIOS-specified SSIF interface at i2c address 0xe, adapter xlp9xx-i2c, slave address 0x0 [ 38.869500] ipmi_ssif: Trying ACPI-specified SSIF interface at i2c address 0xe, adapter xlp9xx-i2c, slave address 0x0 [ 38.914530] ipmi_ssif: Unable to clear message flags: -22 7 c7 [ 38.952429] ipmi_ssif: Unable to clear message flags: -22 7 00 [ 38.994734] ipmi_ssif: Error getting global enables: -22 7 00 [ 39.015877] ipmi_ssif 0-000e: IPMI message handler: Found new BMC (man_id: 0x00b3d1, prod_id: 0x0001, dev_id: 0x20) [ 39.377645] ipmi_ssif i2c-IPI0001:06: IPMI message handler: Found new BMC (man_id: 0x00b3d1, prod_id: 0x0001, dev_id: 0x20) [ 39.387863] ipmi_ssif 0-000e: IPMI message handler: BMC returned incorrect response, expected netfn 7 cmd 42, got netfn 7 cmd 1 ... [NOTE] : Added custom prints to explain the problem. In the above log, ssif_probe is executed simultaneously on two different CPUs. This patch fixes this issue in following way: - Adds ACPI entry also to the 'ssif_infos' list. - Checks the list if SMBIOS is already registered, removes it and adds ACPI. - If ACPI is already registered, it ignores SMBIOS. - Adds mutex lock throughout the probe process to avoid race.

2019-08-16ipmi: Free receive messages when in an oopsCorey Minyard
If the driver handles a response in an oops, it was just ignoring the message. However, the IPMI watchdog timer was counting on the free happening to know when panic-time messages were complete. So free it in all cases. Signed-off-by: Corey Minyard <cminyard@mvista.com>
2019-08-05ipmi_si: Only schedule continuously in the thread in maintenance modeCorey Minyard
ipmi_thread() uses back-to-back schedule() to poll for command completion which, on some machines, can push up CPU consumption and heavily tax the scheduler locks leading to noticeable overall performance degradation. This was originally added so firmware updates through IPMI would complete in a timely manner. But we can't kill the scheduler locks for that one use case. Instead, only run schedule() continuously in maintenance mode, where firmware updates should run. Signed-off-by: Corey Minyard <cminyard@mvista.com>

2019-07-31Bluetooth: hci_uart: check for missing tty operationsVladis Dronov
Certain ttys operations (pty_unix98_ops) lack tiocmget() and tiocmset() functions which are called by the certain HCI UART protocols (hci_ath, hci_bcm, hci_intel, hci_mrvl, hci_qca) via hci_uart_set_flow_control() or directly. This leads to an execution at NULL and can be triggered by an unprivileged user. Fix this by adding a helper function and a check for the missing tty operations in the protocols code. This fixes CVE-2019-10207. The Fixes: lines list commits where calls to tiocm[gs]et() or hci_uart_set_flow_control() were added to the HCI UART protocols.

2019-07-26virtio/s390: fix race on airq_areas[]Halil Pasic
The access to airq_areas was racy ever since the adapter interrupts got introduced to virtio-ccw, but since commit 39c7dcb15892 ("virtio/s390: make airq summary indicators DMA") this became an issue in practice as well. Namely before that commit the airq_info that got overwritten was still functional. After that commit however the two infos share a summary_indicator, which aggravates the situation. Which means auto-online mechanism occasionally hangs the boot with virtio_blk.

Currently nouveau_svm_fault expects nouveau_range_fault to never unlock mmap_sem, but the latter unlocks it for a random selection of error codes. Fix this up by always unlocking mmap_sem for non-zero return values in nouveau_range_fault, and only unlocking it in the caller for successful returns.

The specification for the Toeplitz function doesn't require to set the key explicitly to be symmetric. In case a symmetric functionality is required a symmetric key can be simply used. Wrongly forcing the algorithm to symmetric causes the wrong packet distribution and a performance degradation.

2019-07-25IB/counters: Always initialize the port counter objectParav Pandit
Port counter objects should be initialized even if alloc_stats is unsupported, otherwise QP bind operations in user space can trigger a NULL pointer deference if they try to bind QP on RDMA device which doesn't support counters.
