We've seen that at least some Atmel and N-Trig panels keep the line low as long as they have something to send. The current version of the driver only detects the first edge but then fails to read rest of the reports (as the line is still asserted). Make the driver follow the specification and configure the HID interrupt to be level sensitive. The Windows HID over I2C driver also seems to do the same.

This is triggered in the deferred probing path, resulting in the clock running at a wrong frequency after the successful probe. This can be easily fixed by setting the rate explicitly rather than by relying on the implicit rate inherited by the parent.

It analyzes all the instructions from the beginning of the function until the given address. The code might be modified by another Kprobe. In this case, the current code is read into a buffer, int3 breakpoint is replaced by the saved opcode in the buffer, and can_probe() analyzes the buffer instead. There is a bug that __recover_probed_insn() tries to restore the original code even for Kprobes using the ftrace framework. But in this case, the opcode is not stored. See the difference between arch_prepare_kprobe() and arch_prepare_kprobe_ftrace(). The opcode is stored by arch_copy_kprobe() only from arch_prepare_kprobe(). This patch makes Kprobe to use the ideal 5-byte NOP when the code can be modified by ftrace. It is the original instruction, see ftrace_make_nop() and ftrace_nop_replace(). Note that we always need to use the NOP for ftrace locations. Kprobes do not block ftrace and the instruction might get modified at anytime. It might even be in an inconsistent state because it is modified step by step using the int3 breakpoint. The patch also fixes indentation of the touched comment. Note that I found this problem when playing with Kprobes. I did it on x86_64 with gcc-4.8.3 that supported -mfentry. I modified samples/kprobes/kprobe_example.c and added offset 5 to put the probe right after the fentry area: static struct kprobe kp = { .symbol_name = "do_fork", + .offset = 5, }; Then I was able to load kprobe_example before jprobe_example but not the other way around: $> modprobe jprobe_example $> modprobe kprobe_example modprobe: ERROR: could not insert 'kprobe_example': Invalid or incomplete multibyte or wide character It did not make much sense and debugging pointed to the bug described above.

When we reuse the file, quota structures on disk suddenly have wrong type stored in d_flags though. Nobody really cares about this (although structure type reported to userspace was wrong as well) except that after commit 14bf61ffe6ac (quota: Switch ->get_dqblk() and ->set_dqblk() to use bytes as space units) assertion in xfs_qm_scall_getquota() started to trigger on xfs/106 test (apparently I was testing without XFS_DEBUG so I didn't notice when submitting the above commit). Fix the problem by properly resetting ddq->d_flags when running quotacheck for a quota file.

The blocks beyond EOF get zeroed in memory, but we never force those changes to disk before we run the transaction that extends the file size and exposes those blocks to userspace. This can result in the blocks not being correctly zeroed after a crash. Because in-memory behaviour is correct, tools like fsx don't pick up any coherency problems - it's not until the filesystem is shutdown or the system crashes after writing the truncate transaction to the journal but before the zeroed data in the page cache is flushed that the issue is exposed. Fix this by also flushing the dirty data in memory region between the old size and new size when we've found blocks that need zeroing in the truncate process.

A fully preemptible kernel may deschedule such as task in any upcall called from a hypercall continuation. However, in a kernel with voluntary or no preemption, hypercall continuations in Xen allow event handlers to be run but the task issuing the hypercall will not be descheduled until the hypercall is complete and the ioctl returns to user space. These long running tasks may also trigger the kernel's soft lockup detection. Add xen_preemptible_hcall_begin() and xen_preemptible_hcall_end() to bracket hypercalls that may be preempted. Use these in the privcmd driver. When returning from an upcall, call xen_maybe_preempt_hcall() which adds a schedule point if if the current task was within a preemptible hypercall. Since _cond_resched() can move the task to a different CPU, clear and set xen_in_preemptible_hcall around the call.

Simplify drivers accordingly. Also there is an *_optional variant that serves well here. The sematics is slightly changed here by using it as error checking is more strict now: If GPIOLIB is not enabled an error is returned instead of just ignoring the gpio. On one hand this is bad for devices that don't "have" the respective gpio as the driver is failing now. On the other hand there is no means to assert that this gpio is really not needed or if only the driver to control it is not available. The latter is a real reason to fail and so it's defensive to fail here, too.

MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The STA32X_AUTO3 is a writable register that currently does not appear in the regmap ranges(neither read nor write). By adding this register to the register ranges there is no gap anymore and the existing register ranges can be joined. This fixes a regression introduced in commit a1be4cead9b9504aa6fc93b624975601cec8c188 where the driver was moved to direct regmap usage and the STA32X_AUTO3 register was missed. That made it impossible to choose the preset EQ mode set through the STA32X_AUTO3 register.

These are used to determine which VMA corresponds to the user stack in /proc//maps, and for the user PC & A0StP in /proc//stat. However for Meta the PC & A0StP from the task's kernel context are used, resulting in broken output. For example in following /proc//maps output, the 3afff000-3b021000 VMA should be described as the stack: # cat /proc/self/maps ... 100b0000-100b1000 rwxp 00000000 00:00 0 [heap] 3afff000-3b021000 rwxp 00000000 00:00 0 And in the following /proc//stat output, the PC is in kernel code (1074234964 = 0x40078654) and the A0StP is in the kernel heap (1335981392 = 0x4fa17550): # cat /proc/self/stat 51 (cat) R ... 1335981392 1074234964 ... Fix the definitions of KSTK_EIP() and KSTK_ESP() to use task_pt_regs(tsk)->ctx rather than (tsk)->thread.kernel_context. This gets the registers from the user context stored after the thread info at the base of the kernel stack, which is from the last entry into the kernel from userland, regardless of where in the kernel the task may have been interrupted, which results in the following more correct /proc//maps output: # cat /proc/self/maps ... 0800b000-08070000 r-xp 00000000 00:02 207 /lib/libuClibc-0.9.34-git.so ... 100b0000-100b1000 rwxp 00000000 00:00 0 [heap] 3afff000-3b021000 rwxp 00000000 00:00 0 [stack] And /proc//stat now correctly reports the PC in libuClibc (134320308 = 0x80190b4) and the A0StP in the [stack] region (989864576 = 0x3b002280): # cat /proc/self/stat 51 (cat) R ... 989864576 134320308 ...

Correct the unbalanced refcount & replace the frees. Remove a noisy warning when hitting the request creation path. drm_i915_gem_request and intel_context are both kref reference counted structures. Upon allocation, drm_i915_gem_request's ref count should be bumped using kref_init.

It can be due to another device that is still in D0 state and shares the interrupt line with i915, or on some platforms there could be spurious interrupts even without sharing the interrupt line. The latter case was reported by Klaus Ethgen using a Lenovo x61p machine (gen 4). He noticed this issue via a system suspend/resume hang and bisected it to the following commit: commit e11aa362308f5de467ce355a2a2471321b15a35c Author: Jesse Barnes Date: Wed Jun 18 09:52:55 2014 -0700 drm/i915: use runtime irq suspend/resume in freeze/thaw This is a problem, since in low-power states IIR will always read 0xffffffff resulting in an endless IRQ servicing loop. Fix this by handling interrupts only when the driver explicitly enables them and so it's guaranteed that the interrupt registers return a valid value. Note that this issue existed even before the above commit, since during runtime suspend/resume we never unregistered the handler. v2: - clarify the purpose of smp_mb() vs. synchronize_irq() in the code comment (Chris) v3: - no need for an explicit smp_mb(), we can assume that synchronize_irq() and the mmio read/writes in the install hooks provide for this (Daniel) - remove code comment as the remaining synchronize_irq() is self explanatory (Daniel) v4: - drm_irq_uninstall() implies synchronize_irq(), so no need to call it explicitly (Daniel) Reference: https://lkml.org/lkml/2015/2/11/205 Reported-and-bisected-by: Klaus Ethgen Cc: stable@vger.kernel.org Signed-off-by: Imre Deak Reviewed-by: Daniel Vetter Signed-off-by: Jani Nikula --- drivers/gpu/drm/i915/i915_irq.c | 22 ++++++++++++++++++++++ 1 file changed, 22 insertions(+) diff --git a/drivers/gpu/drm/i915/i915_irq.c b/drivers/gpu/drm/i915/i915_irq.c index 4145d95902f5..ede5bbbd8a08 100644 --- a/drivers/gpu/drm/i915/i915_irq.c +++ b/drivers/gpu/drm/i915/i915_irq.c @@ -1892,6 +1892,9 @@ static irqreturn_t valleyview_irq_handler(int irq, void *arg) u32 iir, gt_iir, pm_iir; irqreturn_t ret = IRQ_NONE; + if (!intel_irqs_enabled(dev_priv)) + return IRQ_NONE; + while (true) { /* Find, clear, then process each source of interrupt */ @@ -1936,6 +1939,9 @@ static irqreturn_t cherryview_irq_handler(int irq, void *arg) u32 master_ctl, iir; irqreturn_t ret = IRQ_NONE; + if (!intel_irqs_enabled(dev_priv)) + return IRQ_NONE; + for (;;) { master_ctl = I915_READ(GEN8_MASTER_IRQ) & ~GEN8_MASTER_IRQ_CONTROL; iir = I915_READ(VLV_IIR); @@ -2208,6 +2214,9 @@ static irqreturn_t ironlake_irq_handler(int irq, void *arg) u32 de_iir, gt_iir, de_ier, sde_ier = 0; irqreturn_t ret = IRQ_NONE; + if (!intel_irqs_enabled(dev_priv)) + return IRQ_NONE; + /* We get interrupts on unclaimed registers, so check for this before we * do any I915_{READ,WRITE}. */ intel_uncore_check_errors(dev); @@ -2279,6 +2288,9 @@ static irqreturn_t gen8_irq_handler(int irq, void *arg) enum pipe pipe; u32 aux_mask = GEN8_AUX_CHANNEL_A; + if (!intel_irqs_enabled(dev_priv)) + return IRQ_NONE; + if (IS_GEN9(dev)) aux_mask |= GEN9_AUX_CHANNEL_B | GEN9_AUX_CHANNEL_C | GEN9_AUX_CHANNEL_D; @@ -3771,6 +3783,9 @@ static irqreturn_t i8xx_irq_handler(int irq, void *arg) I915_DISPLAY_PLANE_A_FLIP_PENDING_INTERRUPT | I915_DISPLAY_PLANE_B_FLIP_PENDING_INTERRUPT; + if (!intel_irqs_enabled(dev_priv)) + return IRQ_NONE; + iir = I915_READ16(IIR); if (iir == 0) return IRQ_NONE; @@ -3951,6 +3966,9 @@ static irqreturn_t i915_irq_handler(int irq, void *arg) I915_DISPLAY_PLANE_B_FLIP_PENDING_INTERRUPT; int pipe, ret = IRQ_NONE; + if (!intel_irqs_enabled(dev_priv)) + return IRQ_NONE; + iir = I915_READ(IIR); do { bool irq_received = (iir & ~flip_mask) != 0; @@ -4171,6 +4189,9 @@ static irqreturn_t i965_irq_handler(int irq, void *arg) I915_DISPLAY_PLANE_A_FLIP_PENDING_INTERRUPT | I915_DISPLAY_PLANE_B_FLIP_PENDING_INTERRUPT; + if (!intel_irqs_enabled(dev_priv)) + return IRQ_NONE; + iir = I915_READ(IIR); for (;;) { @@ -4520,6 +4541,7 @@ void intel_runtime_pm_disable_interrupts(struct drm_i915_private *dev_priv) { dev_priv->dev->driver->irq_uninstall(dev_priv->dev); dev_priv->pm.irqs_enabled = false; + synchronize_irq(dev_priv->dev->irq); } /** From f37b5c2be8979993efee2da50b51126e3908eb8b Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Tue, 10 Feb 2015 23:12:27 +0100 Subject: [PATCH 092/240] drm/i915: Align initial plane backing objects correctly Some bios really like to joke and start the planes at an offset ... hooray!

After testing the USB with actual devices I noticed a few issues that should be fixed to avoid confusion: - The USB id pin on dm8168-evm is hardwired and can be changed only by software. As there are two USB-A type connectors, let's start both in host mode instead of otg. - The Mentor core is configured in such a way on dm8168-evm that it's not capable of multipoint at least on revision c board that I have. - We need ranges for the syscon to properly set up the phy as children of the SCM syscon area. - Let's not disable the second interface, the board specific dts files can do that if really needed. Most boards should just keep it enabled to ensure the device is idled properly. Note that also a phy and several musb fixes are still needed to make the USB to work properly in addition to this fix.

MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When a drive is marked write-mostly it should only be the target of reads if there is no other option. This behaviour was broken by commit 9dedf60313fa4dddfd5b9b226a0ef12a512bf9dc md/raid1: read balance chooses idlest disk for SSD which causes a write-mostly device to be *preferred* is some cases. Restore correct behaviour by checking and setting best_dist_disk and best_pending_disk rather than best_disk. We only need to test one of these as they are both changed from -1 or >=0 at the same time. As we leave min_pending and best_dist unchanged, any non-write-mostly device will appear better than the write-mostly device.

Since there's no architectural way of detecting the cpus that share particular cache, device tree can be used and the core cacheinfo already supports the same. This patch adds the L2 cache topology on Juno board, FVP/RTSM and foundation models.

In that case of course CLKR/CLKX must not be configured as output pin. Otherwise the input clock is messed up horribly. This patch makes it possible to use the CLKR/CLKX pin rather than CLKS to inject a reference clock in setups where McBSP is master and not both rx and tx are used. However for this to work it has to be ensured that set_dai_sysclk() is called after set_dai_fmt(). This was tested on a beagleboard-xm using McBSP1 to drive a i2s DAC through the tx lines (CLKX,FSX,DX). Using this patch the CLKR pin is used to inject an external reference clock.

Nathan Lynch Date: Tue, 24 Feb 2015 17:21:07 -0600 Subject: [PATCH 152/240] arm64: vdso: minor ABI fix for clock_getres The vdso implementation of clock_getres currently returns 0 (success) whenever a null timespec is provided by the caller, regardless of the clock id supplied. This behavior is incorrect. It should fall back to syscall when an unrecognized clock id is passed, even when the timespec argument is null. This ensures that clock_getres always returns an error for invalid clock ids.

When a compat application invokes a syscall that takes a sigval_t value (as part of a larger structure, e.g. compat_sys_mq_notify, compat_sys_timer_create), the compat_sigval_t union is converted to the native sigval_t with sival_int overlapping with either the least or the most significant half of sival_ptr, depending on endianness. When the corresponding signal is delivered to a compat application, on big endian the current (compat_uptr_t)sival_ptr cast always returns 0 since sival_int corresponds to the top part of sival_ptr. This patch fixes copy_siginfo_to_user32() so that sival_int is copied to the compat_siginfo_t structure.

This unifies the row computation into a single function and uses that throughout the TUI code. This also accounts for increasing the number of rows when there are more than 9 total cooling devices.

The change modified cpu_init() in common.c, so that the shadow CR4 gets initialized before anything uses it. Unfortunately, there's two cpu_init()s in common.c. There's one for 64-bit and one for 32-bit. The commit only added the shadow init to the 64-bit path, but the 32-bit path needs the init too.

In this case, freeing pages whose refcount is not 0 won't be freed to the page allocator so memory leak happens. To fix the problem, this patch changes __get_free_pages() to alloc_pages_exact() since alloc_pages_exact() returns physically-contiguous pages but each pages are refcounted.

This leads to interesting side effects e.g. groups/hierarchies with no memory accounted are considered protected and so the reclaim will emit MEMCG_LOW event when encountering them. Another and much bigger issue was reported by Joonsoo Kim. He has hit a NULL ptr dereference with the legacy cgroup API which even doesn't have low limit exposed. The limit is 0 by default but the initial check fails for memcg with 0 consumption and parent_mem_cgroup() would return NULL if use_hierarchy is 0 and so page_counter_read would try to dereference NULL. I suppose that the current implementation is just an overlook because the documentation in Documentation/cgroups/unified-hierarchy.txt says: "The memory.low boundary on the other hand is a top-down allocated reserve. A cgroup enjoys reclaim protection when it and all its ancestors are below their low boundaries" Fix the usage and the low limit comparision in mem_cgroup_low accordingly.

Since the value of "bn_nchildren" is used for operations on the key-values within the b-tree node, it can cause memory access overrun if a large number is incorrectly set to "bn_nchildren". For instance, nilfs_btree_node_lookup() function determines the range of binary search with it, and too large "bn_nchildren" leads nilfs_btree_node_get_key() in that function to overrun. As for intermediate b-tree nodes, this is prevented by a sanity check performed when each node is read from a drive, however, no sanity check has been done for root nodes stored in inodes. This patch fixes the issue by adding missing sanity check against b-tree root nodes so that it's called when on-memory inodes are read from ifile, inode metadata file.

The bug at hand is an underrun of the framebuffer reference with subsequent hilarity caused by the load detect code. Which is peculiar since the the exact same code works fine as the implementation of the legacy setcrtc ioctl. Let's look at the ingredients: - Currently our code is a crazy mix of legacy modeset interfaces to set the parameters and half-baked atomic state tracking underneath. While this transition is going we're using the transitional plane helpers to update the atomic side (drm_plane_helper_disable/update and friends), i.e. plane->state->fb. Since the state structure owns the fb those functions take care of that themselves. The legacy state (specifically crtc->primary->fb) is still managed by the old code (and mostly by the drm core), with the fb reference counting done by callers (core drm for the ioctl or the i915 load detect code). The relevant commit is commit ea2c67bb4affa84080c616920f3899f123786e56 Author: Matt Roper Date: Tue Dec 23 10:41:52 2014 -0800 drm/i915: Move to atomic plane helpers (v9) - drm_plane_helper_disable has special code to handle multiple calls in a row - it checks plane->crtc == NULL and bails out. This is to match the proper atomic implementation which needs the crtc to get at the implied locking context atomic updates always need. See commit acf24a395c5a9290189b080383564437101d411c Author: Daniel Vetter Date: Tue Jul 29 15:33:05 2014 +0200 drm/plane-helper: transitional atomic plane helpers - The universal plane code split out the implicit primary plane from the CRTC into it's own full-blown drm_plane object. As part of that the setcrtc ioctl (which updated both the crtc mode and primary plane) learned to set crtc->primary->crtc on modeset to make sure the plane->crtc assignments statate up to date in commit e13161af80c185ecd8dc4641d0f5df58f9e3e0af Author: Matt Roper Date: Tue Apr 1 15:22:38 2014 -0700 drm: Add drm_crtc_init_with_planes() (v2) Unfortunately we've forgotten to update the load detect code. Which wasn't a problem since the load detect modeset is temporary and always undone before we drop the locks. - Finally there is a organically grown history (i.e. don't ask) around who sets the legacy plane->fb for the various driver entry points. Originally updating that was the drivers duty, but for almost all places we've moved that (plus updating the refcounts) into the core. Again the exception is the load detect code. Taking all together the following happens: - The load detect code doesn't set crtc->primary->crtc. This is only really an issue on crtcs never before used or when userspace explicitly disabled the primary plane. - The plane helper glue code short-circuits because of that and leaves a non-NULL fb behind in plane->state->fb and plane->fb. The state fb isn't a real problem (it's properly refcounted on its own), it's just the canary. - Load detect code drops the reference for that fb, but doesn't set plane->fb = NULL. This is ok since it's still living in that old world where drivers had to clear the pointer but the core/callers handled the refcounting. - On the next modeset the drm core notices plane->fb and takes care of refcounting it properly by doing another unref. This drops the refcount to zero, leaving state->plane now pointing at freed memory. - intel_plane_duplicate_state still assume it owns a reference to that very state->fb and bad things start to happen. Fix this all by applying the same duct-tape as for the legacy setcrtc ioctl code and set crtc->primary->crtc properly.

When it was originally introduced snd_soc_jack_new() took a snd_soc_card as its parameter, but at that time DAPM was only implemented at the CODEC level and there was only one CODEC per card. This made it clear which CODEC to use for the jack DAPM operations. But the multi-component patchset added support for having multiple CODECs per card and with it the API was updated to register jacks with a specific CODEC instance instead. Subsequently DAPM support at the card level has been introduced, but the snd_soc_jack_new() API has so remained unchanged. This leaves us with the issue that the DAPM pins that are managed by the jack detection logic usually are part of the card DAPM context but are accessed through a CODEC DAPM context. Currently this works fine, but might break in the future if we take a more hierarchical approach to DAPM contexts. Furthermore with componentization progressing systems that do not register a snd_soc_codec might appear, while these system may still want to able to register a jack. This patch addresses these issues by adding a new function called snd_soc_card_jack_new() that can be used to register jacks with the card rather than a CODEC. This new function is mostly identical to snd_soc_jack_new() except that it additionally allows to directly specify the DAPM pins associated with the jack. This was done since most users of snd_soc_jack_new() typically call snd_soc_jack_add_pins() right after it, which is not necessary with the new API and allows to reduce the amount of boiler plate code. The old snd_soc_jack_new() is re-implemented as a wrapper around snd_soc_card_jack_new().
