7f55656 Hugh Dickins 10 July 2016, 23:46:32 UTC tmpfs: fix regression hang in fallocate undo The well-spotted fallocate undo fix is good in most cases, but not when fallocate failed on the very first page. index 0 then passes lend -1 to shmem_undo_range(), and that has two bad effects: (a) that it will undo every fallocation throughout the file, unrestricted by the current range; but more importantly (b) it can cause the undo to hang, because lend -1 is treated as truncation, which makes it keep on retrying until every page has gone, but those already fully instantiated will never go away. Big thank you to xfstests generic/269 which demonstrates this.

6f2d9d9 Jan Beulich 08 July 2016, 12:15:07 UTC xen/acpi: allow xen-acpi-processor driver to load on Xen 4.7 As of Xen 4.7 PV CPUID doesn't expose either of CPUID[1].ECX[7] and CPUID[0x80000007].EDX[7] anymore, causing the driver to fail to load on both Intel and AMD systems. Doing any kind of hardware capability checks in the driver as a prerequisite was wrong anyway: With the hypervisor being in charge, all such checking should be done by it. If ACPI data gets uploaded despite some missing capability, the hypervisor is free to ignore part or all of that data. Ditch the entire check_prereq() function, and do the only valid check (xen_initial_domain()) in the caller in its place.

7469be9 Jan Beulich 07 July 2016, 07:32:04 UTC xenbus: don't bail early from xenbus_dev_request_and_reply() xenbus_dev_request_and_reply() needs to track whether a transaction is open. For XS_TRANSACTION_START messages it calls transaction_start() and for XS_TRANSACTION_END messages it calls transaction_end(). If sending an XS_TRANSACTION_START message fails or responds with an an error, the transaction is not open and transaction_end() must be called. If sending an XS_TRANSACTION_END message fails, the transaction is still open, but if an error response is returned the transaction is closed. Commit 027bd7e89906 ("xen/xenbus: Avoid synchronous wait on XenBus stalling shutdown/restart") introduced a regression where failed XS_TRANSACTION_START messages were leaving the transaction open. This can cause problems with suspend (and migration) as all transactions must be closed before suspending. It appears that the problematic change was added accidentally, so just remove it.

2c81a64 Mark Rutland 14 June 2016, 15:10:41 UTC perf/core: Fix pmu::filter_match for SW-led groups The following commit: 66eb579e66ec ("perf: allow for PMU-specific event filtering") added the pmu::filter_match() callback. This was intended to avoid HW constraints on events from resulting in extremely pessimistic scheduling. However, pmu::filter_match() is only called for the leader of each event group. When the leader is a SW event, we do not filter the groups, and may fail at pmu::add() time, and when this happens we'll give up on scheduling any event groups later in the list until they are rotated ahead of the failing group. This can result in extremely sub-optimal event scheduling behaviour, e.g. if running the following on a big.LITTLE platform: $ taskset -c 0 ./perf stat \ -e 'a57{context-switches,armv8_cortex_a57/config=0x11/}' \ -e 'a53{context-switches,armv8_cortex_a53/config=0x11/}' \ ls <not counted> context-switches (0.00%) <not counted> armv8_cortex_a57/config=0x11/ (0.00%) 24 context-switches (37.36%) 57589154 armv8_cortex_a53/config=0x11/ (37.36%) Here the 'a53' event group was always eligible to be scheduled, but the 'a57' group never eligible to be scheduled, as the task was always affine to a Cortex-A53 CPU. The SW (group leader) event in the 'a57' group was eligible, but the HW event failed at pmu::add() time, resulting in ctx_flexible_sched_in giving up on scheduling further groups with HW events. One way of avoiding this is to check pmu::filter_match() on siblings as well as the group leader.

However, after fixing a deadlock bug in commit 9c7370a166b4 ("ipv6: Fix a potential deadlock when creating pcpu rt"), free_percpu() is not called before setting non_pcpu_rt->rt6i_pcpu to NULL. It is worth to note that rt6i_pcpu is protected by table->tb6_lock. kmemleak somehow did not report it.

4520904 Lv Zheng 05 July 2016, 05:53:12 UTC ACPICA: Namespace: Fix namespace/interpreter lock ordering There is a lock order issue in acpi_load_tables(). The namespace lock is held before holding the interpreter lock. With ACPI_MUTEX_DEBUG enabled in the kernel, this is printed to the log during boot: [ 0.885699] ACPI Error: Invalid acquire order: Thread 405884224 owns [ACPI_MTX_Namespace], wants [ACPI_MTX_Interpreter] (20160422/utmutex-263) [ 0.885881] ACPI Error: Could not acquire AML Interpreter mutex (20160422/exutils-95) [ 0.893846] ACPI Error: Mutex [0x0] is not acquired, cannot release (20160422/utmutex-326) [ 0.894019] ACPI Error: Could not release AML Interpreter mutex (20160422/exutils-133) The issue has been introduced by the following commit: Commit: 2f38b1b16d9280689e5cfa47a4c50956bf437f0d ACPICA Commit: bfe03ffcde8ed56a7eae38ea0b188aeb12f9c52e Subject: ACPICA: Namespace: Fix a regression that MLC support triggers dead lock in dynamic table loading Which fixed a deadlock issue for acpi_ns_load_table() in acpi_ex_add_table() but didn't take care of the lock order in acpi_ns_load_table() correctly. Originally (before the above commit), ACPICA used the namespace/interpreter locks in the following 2 key code paths: 1. Table loading: acpi_ns_load_table L(Namespace) acpi_ns_parse_table acpi_ns_one_complete_parse U(Namespace) 2. Object evaluation: acpi_ns_evaluate L(Interpreter) acpi_ps_execute_method U(Interpreter) acpi_ns_load_table L(Namespace) U(Namespace) acpi_ev_initialize_region L(Namespace) U(Namespace) address_space.setup L(Namespace) U(Namespace) address_space.handler L(Namespace) U(Namespace) acpi_os_wait_semaphore acpi_os_acquire_mutex acpi_os_sleep L(Interpreter) U(Interpreter) During runtime, while acpi_ns_evaluate is called, the lock order is always Interpreter -> Namespace. In turn, the problematic commit acquires the locks in the following order: 3. Table loading: acpi_ns_load_table L(Namespace) acpi_ns_parse_table L(Interpreter) acpi_ns_one_complete_parse U(Interpreter) U(Namespace) To fix the lock order issue, move the interpreter lock to acpi_ns_load_table() to ensure the lock order correctness: 4. Table loading: acpi_ns_load_table L(Interpreter) L(Namespace) acpi_ns_parse_table acpi_ns_one_complete_parse U(Namespace) U(Interpreter) However, this doesn't fix the current design issues related to the namespace lock. For example, we can notice that in acpi_ns_evaluate(), outside of acpi_ns_load_table(), the namespace objects may be created by the named object creation control methods. And the creation of the method-owned namespace objects are not locked by the namespace lock. This patch doesn't try to fix such kind of existing issues.

a30b016 Aviv Heller 05 July 2016, 09:09:47 UTC bonding: fix enslavement slave link notifications Currently, link notifications are not sent by bond_set_slave_link_state() upon enslavement if the slave is enslaved when up. This happens because slave->link default init value is 0, which is the same as BOND_LINK_UP, resulting in bond_set_slave_link_state() ignoring this transition. This patch sets the default value of slave->link to BOND_LINK_NOCHANGE, assuring it will count as a state transition and thus trigger notification logic.

547aefc Paul Burton 05 July 2016, 13:26:00 UTC irqchip/mips-gic: Match IPI IRQ domain by bus token only Commit fbde2d7d8290 ("MIPS: Add generic SMP IPI support") introduced code which calls irq_find_matching_host with a NULL node parameter in order to discover IPI IRQ domains which are not associated with the DT root node's interrupt parent. This suggests that implementations of IPI IRQ domains should effectively ignore the node parameter if it is NULL and search purely based upon the bus token. Commit 2af70a962070 ("irqchip/mips-gic: Add a IPI hierarchy domain") did not do this when implementing the GIC IPI IRQ domain, and on MIPS Boston boards this leads to no IPI domain being discovered and a NULL pointer dereference when attempting to send an IPI: CPU 0 Unable to handle kernel paging request at virtual address 0000000000000040, epc == ffffffff8016e70c, ra == ffffffff8010ff5c Oops[#1]: CPU: 0 PID: 1 Comm: swapper/0 Not tainted 4.7.0-rc6-00223-gad0d1b6 #945 task: a8000000ff066fc0 ti: a8000000ff068000 task.ti: a8000000ff068000 $ 0 : 0000000000000000 0000000000000001 ffffffff80730000 0000000000000003 $ 4 : 0000000000000000 ffffffff8057e5b0 a800000001e3ee00 0000000000000000 $ 8 : 0000000000000000 0000000000000023 0000000000000001 0000000000000001 $12 : 0000000000000000 ffffffff803323d0 0000000000000000 0000000000000000 $16 : 0000000000000000 0000000000000000 0000000000000001 ffffffff801108fc $20 : 0000000000000000 ffffffff8057e5b0 0000000000000001 0000000000000000 $24 : 0000000000000000 ffffffff8012de28 $28 : a8000000ff068000 a8000000ff06fbc0 0000000000000000 ffffffff8010ff5c Hi : ffffffff8014c174 Lo : a800000001e1e140 epc : ffffffff8016e70c __ipi_send_mask+0x24/0x11c ra : ffffffff8010ff5c mips_smp_send_ipi_mask+0x68/0x178 Status: 140084e2 KX SX UX KERNEL EXL Cause : 00800008 (ExcCode 02) BadVA : 0000000000000040 PrId : 0001a920 (MIPS I6400) Process swapper/0 (pid: 1, threadinfo=a8000000ff068000, task=a8000000ff066fc0, tls=0000000000000000) Stack : 0000000000000000 0000000000000000 0000000000000001 ffffffff801108fc 0000000000000000 ffffffff8057e5b0 0000000000000001 ffffffff8010ff5c 0000000000000001 0000000000000020 0000000000000000 0000000000000000 0000000000000000 ffffffff801108fc 0000000000000000 0000000000000001 0000000000000001 0000000000000000 0000000000000000 ffffffff801865e8 a8000000ff0c7500 a8000000ff06fc90 0000000000000001 0000000000000002 ffffffff801108fc ffffffff801868b8 0000000000000000 ffffffff801108fc 0000000000000000 0000000000000003 ffffffff8068c700 0000000000000001 ffffffff80730000 0000000000000001 a8000000ff00a290 ffffffff80110c50 0000000000000003 a800000001e48308 0000000000000003 0000000000000008 ...

99ec8a3 Paul Burton 05 July 2016, 13:25:59 UTC irqchip/mips-gic: Map to VPs using HW VPNum When mapping an interrupt to a VP(E) we must use the identifier for the VP that the hardware expects, and this does not always match up with the Linux CPU number. Commit d46812bb0bef ("irqchip: mips-gic: Use HW IDs for VPE_OTHER_ADDR") corrected this for the cases that existed at the time it was written, but commit 2af70a962070 ("irqchip/mips-gic: Add a IPI hierarchy domain") added another case before the former patch was merged. This leads to incorrectly using Linux CPU numbers when mapping interrupts to VPs, which breaks on certain systems such as those with multi-core I6400 CPUs. Fix by adding the appropriate call to mips_cm_vp_id() to retrieve the expected VP identifier.

c086e70 Bjørn Mork 03 July 2016, 20:24:50 UTC cdc_ncm: workaround for EM7455 "silent" data interface Several Lenovo users have reported problems with their Sierra Wireless EM7455 modem. The driver has loaded successfully and the MBIM management channel has appeared to work, including establishing a connection to the mobile network. But no frames have been received over the data interface. The problem affects all EM7455 and MC7455, and is assumed to affect other modems based on the same Qualcomm chipset and baseband firmware. Testing narrowed the problem down to what seems to be a firmware timing bug during initialization. Adding a short sleep while probing is sufficient to make the problem disappear. Experiments have shown that 1-2 ms is too little to have any effect, while 10-20 ms is enough to reliably succeed.

85b03b3 Johan Hovold 03 July 2016, 16:32:05 UTC Revert "gpiolib: Split GPIO flags parsing and GPIO configuration" This reverts commit 923b93e451db876d1479d3e4458fce14fec31d1c. Make sure consumers do not overwrite gpio flags for pins that have already been claimed. While adding support for gpio drivers to refuse a request using unsupported flags, the order of when the requested flag was checked and the new flags were applied was reversed to that consumers could overwrite flags for already requested gpios. This not only affects device-tree setups where two drivers could request the same gpio using conflicting configurations, but also allowed user space to clear gpio flags for already claimed pins simply by attempting to export them through the sysfs interface. By for example clearing the FLAG_ACTIVE_LOW flag this way, user space could effectively change the polarity of a signal. Reverting this change obviously prevents gpio drivers from doing sanity checks on the flags in their request callbacks. Fortunately only one recently added driver (gpio-tps65218 in v4.6) appears to do this, and a follow up patch could restore this functionality through a different interface.

87041a5 Colin Pitrat 18 June 2016, 18:05:04 UTC gpio: sch: Fix Oops on module load on Asus Eee PC 1201 This fixes the issue descirbe in bug 117531 (https://bugzilla.kernel.org/show_bug.cgi?id=117531). It's a regression introduced in linux 4.5 that causes a Oops at load of gpio_sch and prevents powering off the computer. The issue is that sch_gpio_reg_set is called in sch_gpio_probe before gpio_chip data is initialized with the pointer to the sch_gpio struct. As sch_gpio_reg_set calls gpiochip_get_data, it returns NULL which causes the Oops. The patch follows Mika's advice (https://lkml.org/lkml/2016/5/9/61) and consists in modifying sch_gpio_reg_get and sch_gpio_reg_set to take a sch_gpio struct directly instead of a gpio_chip, which avoids the call to gpiochip_get_data.

dbd1b8e Shreyas B. Prabhu 01 July 2016, 14:24:14 UTC cpuidle: Fix last_residency division Snooze is a poll idle state in powernv and pseries platforms. Snooze has a timeout so that if a CPU stays in snooze for more than target residency of the next available idle state, then it would exit thereby giving chance to the cpuidle governor to re-evaluate and promote the CPU to a deeper idle state. Therefore whenever snooze exits due to this timeout, its last_residency will be target_residency of the next deeper state. Commit e93e59ce5b85 "cpuidle: Replace ktime_get() with local_clock()" changed the math around last_residency calculation. Specifically, while converting last_residency value from nano- to microseconds, it carries out right shift by 10. Because of that, in snooze timeout exit scenarios last_residency calculated is roughly 2.3% less than target_residency of the next available state. This pattern is picked up by get_typical_interval() in the menu governor and therefore expected_interval in menu_select() is frequently less than the target_residency of any state other than snooze. Due to this we are entering snooze at a higher rate, thereby affecting the single thread performance. Fix this by using more precise division via ktime_us_delta().

This results in bogus read outs, and the endless loop in the user-space side.

373819e Sergio Valverde 01 July 2016, 17:44:30 UTC enc28j60: Fix race condition in enc28j60 driver The interrupt worker code for the enc28j60 relies only on the TXIF flag to determinate if the packet transmission was completed. However the datasheet specifies in section 12.1.3 that TXERIF will clear the TXRTS after a transmit abort. Also in section 12.1.4 that TXIF will be set when TXRTS transitions from '1' to '0'. Therefore the TXIF flag is enabled during transmission errors. This causes a race condition, since the worker code will invoke enc28j60_tx_clear() -> netif_wake_queue(), potentially invoking the ndo_start_xmit function to send a new packet. The enc28j60_send_packet function uses a workqueue that invokes enc28j60_hw_tx(). In between this function is called, the worker from the interrupt handler will enter the path for error handler because of the TXERIF flag, causing to invoke enc28j60_tx_clear() again and releasing the packet scheduled for transmission, causing a kernel crash with due a NULL pointer. These crashes due a NULL pointer were observed under stress conditions of the device. A BUG_ON() sequence was used to validate the issue was fixed, and has been running without problems for 2 years now.

The following testcase may result in a page table entries with a invalid CCA field being generated: static void *bindstack; static int sysrqfd; static void protect_low(int protect) { mprotect(bindstack, BINDSTACK_SIZE, protect); } static void sigbus_handler(int signal, siginfo_t * info, void *context) { void *addr = info->si_addr; write(sysrqfd, "x", 1); printf("sigbus, fault address %p (should not happen, but might)\n", addr); abort(); } static void run_bind_test(void) { unsigned int *p = bindstack; p[0] = 0xf001f001; write(sysrqfd, "x", 1); /* Set trap on access to p[0] */ protect_low(PROT_NONE); write(sysrqfd, "x", 1); /* Clear trap on access to p[0] */ protect_low(PROT_READ | PROT_WRITE | PROT_EXEC); write(sysrqfd, "x", 1); /* Check the contents of p[0] */ if (p[0] != 0xf001f001) { write(sysrqfd, "x", 1); /* Reached, but shouldn't be */ printf("badness, shouldn't happen but does\n"); abort(); } } int main(void) { struct sigaction sa; sysrqfd = open("/proc/sysrq-trigger", O_WRONLY); if (sigprocmask(SIG_BLOCK, NULL, &sa.sa_mask)) { perror("sigprocmask"); return 0; } sa.sa_sigaction = sigbus_handler; sa.sa_flags = SA_SIGINFO | SA_NODEFER | SA_RESTART; if (sigaction(SIGBUS, &sa, NULL)) { perror("sigaction"); return 0; } bindstack = mmap(NULL, BINDSTACK_SIZE, PROT_READ | PROT_WRITE | PROT_EXEC, MAP_PRIVATE | MAP_ANONYMOUS, -1, 0); if (bindstack == MAP_FAILED) { perror("mmap bindstack"); return 0; } printf("bindstack: %p\n", bindstack); run_bind_test(); printf("done\n"); return 0; } There are multiple ingredients for this: 1) PAGE_NONE is defined to _CACHE_CACHABLE_NONCOHERENT, which is CCA 3 on all platforms except SB1 where it's CCA 5. 2) _page_cachable_default must have bits set which are not set _CACHE_CACHABLE_NONCOHERENT. 3) Either the defective version of pte_modify for XPA or the standard version must be in used. However pte_modify for the 36 bit address space support is no affected. In that case additional bits in the final CCA mode may generate an invalid value for the CCA field. On the R10000 system where this was tracked down for example a CCA 7 has been observed, which is Uncached Accelerated. Fixed by: 1) Using the proper CCA mode for PAGE_NONE just like for all the other PAGE_* pte/pmd bits. 2) Fix the two affected variants of pte_modify. Further code inspection also shows the same issue to exist in pmd_modify which would affect huge page systems. Issue in pte_modify tracked down by Alastair Bridgewater, PAGE_NONE and pmd_modify issue found by me. The history of this goes back beyond Linus' git history. Chris Dearman's commit 351336929ccf222ae38ff0cb7a8dd5fd5c6236a0 ("[MIPS] Allow setting of the cache attribute at run time.") missed the opportunity to fix this but it was originally introduced in lmo commit d523832cf12007b3242e50bb77d0c9e63e0b6518 ("Missing from last commit.") and 32cc38229ac7538f2346918a09e75413e8861f87 ("New configuration option CONFIG_MIPS_UNCACHED.")

f7eca37 Sinan Kaya 29 June 2016, 08:27:37 UTC ACPI,PCI,IRQ: separate ISA penalty calculation Since commit 103544d86976 (ACPI,PCI,IRQ: reduce resource requirements) the penalty values are calculated on the fly rather than at boot time. This works fine for PCI interrupts but not so well for ISA interrupts. The information on whether or not an ISA interrupt is in use is not available to the pci_link.c code directly. That information is obtained from the outside via acpi_penalize_isa_irq(). [If its "active" argument is true, then the IRQ is in use by ISA.] Since the current code relies on PCI Link objects for determination of penalties, we are factoring in the PCI penalty twice after acpi_penalize_isa_irq() function is called. To avoid that, limit the newly added functionality to just PCI interrupts so that old behavior is still maintained.

487cf91 Sinan Kaya 29 June 2016, 08:27:36 UTC Revert "ACPI, PCI, IRQ: remove redundant code in acpi_irq_penalty_init()" Trying to make the ISA and PCI init functionality common turned out to be a bad idea, because the ISA path depends on external functionality. Restore the previous behavior and limit the refactoring to PCI interrupts only.

4a6e68b Sinan Kaya 29 June 2016, 08:27:35 UTC ACPI,PCI,IRQ: factor in PCI possible The change introduced in commit 103544d86976 (ACPI,PCI,IRQ: reduce resource requirements) omitted the initially applied PCI_POSSIBLE penalty when the IRQ is active. Incorrect calculation of the penalty leads the ACPI code to assigning a wrong interrupt number to a PCI INTx interrupt. This would not be as bad as it sounds in theory. It would just cause the interrupts to be shared and result in performance penalty. However, some drivers (like the parallel port driver) don't like interrupt sharing and in the above case they will causes all of the PCI drivers wanting to share the interrupt to be unable to request it. The issue has not been caught in testing because the behavior is platform-specific and depends on the peripherals ending up sharing the IRQ and their drivers. Before the above commit the code would add the PCI_POSSIBLE value divided by the number of possible IRQ users to the IRQ penalty during initialization. Later in that code path, if the IRQ is chosen as the active IRQ or if it is used by ISA; additional penalties are added.
