Markus Trippelsdorf reported that this commit broke 'perf top': > I just see a gray screen with no text at all. Sometimes the > following error messages are printed: > > *** Error in `perf': invalid fastbin entry (free): 0x00000000029b18c0 > *** > *** Error in `perf': malloc(): memory corruption (fast): 0x0000000000ee0b10 *** While this code is fixable, the commit itself fails on several levels: - it should have been a separate helper function - why the heck does it do strchr() twice - it casts a const char * over into char * - sloppy style - it's not even a regression fix! So lets revert it and re-try the patch in v3.13.

Specifics: 1) After the recent locking changes in the cpufreq core it is possible to trigger BUG_ON(!policy) in lock_policy_rwsem_read() if cpufreq_get() is called before registering a cpufreq driver. Fix from Viresh Kumar. 2) If intel_pstate has been loaded already, it doesn't make sense to do anything in acpi_cpufreq_init() and moreover doing something in there in that case may be harmful, so make that function return immediately if another cpufreq driver is already present. From Yinghai Lu. 3) The ACPI IPMI driver sometimes attempts to acquire a mutex from interrupt context, which can be avoided by replacing that mutex with a spinlock. From Lv Zheng. 4) A NULL pointer may be dereferenced by the exynos5440 cpufreq driver if a memory allocation made by it fails. Fix from Sachin Kamat. 5) Hanjun Guo's commit fixes a typo in the kerneldoc comment documenting acpi_bus_unregister_driver()" * tag 'pm+acpi-3.12-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI / scan: fix typo in comments of acpi_bus_unregister_driver() cpufreq: exynos5440: Fix potential NULL pointer dereference cpufreq: check cpufreq driver is valid and cpufreq isn't disabled in cpufreq_get() acpi-cpufreq: skip loading acpi_cpufreq after intel_pstate ACPI / IPMI: Fix atomic context requirement of ipmi_msg_handler() 28 September 2013, 20:27:31 UTC
f41f064 Yinghai Lu 28 September 2013, 20:13:07 UTC PCI: Workaround missing pci_set_master in pci drivers Ben Herrenschmidt found that commit 928bea964827 ("PCI: Delay enabling bridges until they're needed") breaks PCI in some powerpc environments. The reason is that the PCIe port driver will call pci_enable_device() on the bridge, so the device is enabled, but skips pci_set_master because pcie_port_auto and no acpi on powerpc. Because of that, pci_enable_bridge() later on (called as a result of the child device driver doing pci_enable_device) will see the bridge as already enabled and will not call pci_set_master() on it. Fixed by add checking in pci_enable_bridge, and call pci_set_master if driver skip that. That will make the code more robot and wade off problem for missing pci_set_master in drivers.

So we are talking of several thousand cycles. Considering this enabling the lockless lockref variant would contradict the intention of the new semantics. And also some quick measurements show performance regressions of 50% and more. Simply removing the cpu_relax() call again seems also not very desireable since Waiman Long reported that for some workloads the call improved performance by 5%." * 'lockref' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: s390: enable ARCH_USE_CMPXCHG_LOCKREF lockref: use arch_mutex_cpu_relax() in CMPXCHG_LOOP() mutex: replace CONFIG_HAVE_ARCH_MUTEX_CPU_RELAX with simple ifdef 28 September 2013, 19:36:19 UTC

d2212b4 Will Deacon 26 September 2013, 16:27:00 UTC lockref: allow relaxed cmpxchg64 variant for lockless updates The 64-bit cmpxchg operation on the lockref is ordered by virtue of hazarding between the cmpxchg operation and the reference count manipulation. On weakly ordered memory architectures (such as ARM), it can be of great benefit to omit the barrier instructions where they are not needed. This patch moves the lockless lockref code over to a cmpxchg64_relaxed operation, which doesn't provide barrier semantics. If the operation isn't defined, we simply #define it as the usual 64-bit cmpxchg macro.

bd63ace Chew, Chiau Ee 26 September 2013, 18:57:35 UTC i2c: designware: 10-bit addressing mode enabling if I2C_DYNAMIC_TAR_UPDATE is set According to Designware I2C spec, if I2C_DYNAMIC_TAR_UPDATE is set to 1, the 10-bit addressing mode is controlled by IC_10BITADDR_MASTER bit of IC_TAR register instead of IC_CON register. The IC_10BITADDR_MASTER in IC_CON register becomes read-only copy. Since I2C_DYNAMIC_TAR_UPDATE value can't be detected from hardware register, so we will always set the IC_10BITADDR_MASTER bit in both IC_CON and IC_TAR register whenever 10-bit addresing mode is requested by user application.

2606b28 Al Viro 20 September 2013, 16:14:21 UTC USB: Fix breakage in ffs_fs_mount() There's a bunch of failure exits in ffs_fs_mount() with seriously broken recovery logics. Most of that appears to stem from misunderstanding of the ->kill_sb() semantics; unlike ->put_super() it is called for *all* superblocks of given type, no matter how (in)complete the setup had been. ->put_super() is called only if ->s_root is not NULL; any failure prior to setting ->s_root will have the call of ->put_super() skipped. ->kill_sb(), OTOH, awaits every superblock that has come from sget(). Current behaviour of ffs_fs_mount(): We have struct ffs_sb_fill_data data on stack there. We do ffs_dev = functionfs_acquire_dev_callback(dev_name); and store that in data.private_data. Then we call mount_nodev(), passing it ffs_sb_fill() as a callback. That will either fail outright, or manage to call ffs_sb_fill(). There we allocate an instance of struct ffs_data, slap the value of ffs_dev (picked from data.private_data) into ffs->private_data and overwrite data.private_data by storing ffs into an overlapping member (data.ffs_data). Then we store ffs into sb->s_fs_info and attempt to set the rest of the things up (root inode, root dentry, then create /ep0 there). Any of those might fail. Should that happen, we get ffs_fs_kill_sb() called before mount_nodev() returns. If mount_nodev() fails for any reason whatsoever, we proceed to functionfs_release_dev_callback(data.ffs_data); That's broken in a lot of ways. Suppose the thing has failed in allocation of e.g. root inode or dentry. We have functionfs_release_dev_callback(ffs); ffs_data_put(ffs); done by ffs_fs_kill_sb() (ffs accessed via sb->s_fs_info), followed by functionfs_release_dev_callback(ffs); from ffs_fs_mount() (via data.ffs_data). Note that the second functionfs_release_dev_callback() has every chance to be done to freed memory. Suppose we fail *before* root inode allocation. What happens then? ffs_fs_kill_sb() doesn't do anything to ffs (it's either not called at all, or it doesn't have a pointer to ffs stored in sb->s_fs_info). And functionfs_release_dev_callback(data.ffs_data); is called by ffs_fs_mount(), but here we are in nasal daemon country - we are reading from a member of union we'd never stored into. In practice, we'll get what we used to store into the overlapping field, i.e. ffs_dev. And then we get screwed, since we treat it (struct gfs_ffs_obj * in disguise, returned by functionfs_acquire_dev_callback()) as struct ffs_data *, pick what would've been ffs_data ->private_data from it (*well* past the actual end of the struct gfs_ffs_obj - struct ffs_data is much bigger) and poke in whatever it points to. FWIW, there's a minor leak on top of all that in case if ffs_sb_fill() fails on kstrdup() - ffs is obviously forgotten. The thing is, there is no point in playing all those games with union. Just allocate and initialize ffs_data *before* calling mount_nodev() and pass a pointer to it via data.ffs_data. And once it's stored in sb->s_fs_info, clear data.ffs_data, so that ffs_fs_mount() knows that it doesn't need to kill the sucker manually - from that point on we'll have it done by ->kill_sb().

f123db8 Benson Leung 25 September 2013, 03:05:11 UTC driver core : Fix use after free of dev->parent in device_shutdown The put_device(dev) at the bottom of the loop of device_shutdown may result in the dev being cleaned up. In device_create_release, the dev is kfreed. However, device_shutdown attempts to use the dev pointer again after put_device by referring to dev->parent. Copy the parent pointer instead to avoid this condition. This bug was found on Chromium OS's chromeos-3.8, which is based on v3.8.11. See bug report : https://code.google.com/p/chromium/issues/detail?id=297842 This can easily be reproduced when shutting down with hidraw devices that report battery condition. Two examples are the HP Bluetooth Mouse X4000b and the Apple Magic Mouse. For example, with the magic mouse : The dev in question is "hidraw0" dev->parent is "magicmouse" In the course of the shutdown for this device, the input event cleanup calls a put on hidraw0, decrementing its reference count. When we finally get to put_device(dev) in device_shutdown, kobject_cleanup is called and device_create_release does kfree(dev). dev->parent is no longer valid, and we may crash in put_device(dev->parent).

Subsystems that are not registered can't have are not involved so can't have a reason to prevent mounting sysfs. This is a bug-fix to: commit 7dc5dbc879bd0779924b5132a48b731a0bc04a1e Author: Eric W. Biederman <ebiederm@xmission.com> Date: Mon Mar 25 20:07:01 2013 -0700 sysfs: Restrict mounting sysfs Don't allow mounting sysfs unless the caller has CAP_SYS_ADMIN rights over the net namespace. The principle here is if you create or have capabilities over it you can mount it, otherwise you get to live with what other people have mounted. Instead of testing this with a straight forward ns_capable call, perform this check the long and torturous way with kobject helpers, this keeps direct knowledge of namespaces out of sysfs, and preserves the existing sysfs abstractions.

997def2 Mark Tinguely 23 September 2013, 17:18:58 UTC xfs: fix node forward in xfs_node_toosmall Commit f5ea1100 cleans up the disk to host conversions for node directory entries, but because a variable is reused in xfs_node_toosmall() the next node is not correctly found. If the original node is small enough (<= 3/8 of the node size), this change may incorrectly cause a node collapse when it should not. That will cause an assert in xfstest generic/319: Assertion failed: first <= last && last < BBTOB(bp->b_length), file: /root/newest/xfs/fs/xfs/xfs_trans_buf.c, line: 569 Keep the original node header to get the correct forward node. (When a node is considered for a merge with a sibling, it overwrites the sibling pointers of the original incore nodehdr with the sibling's pointers. This leads to loop considering the original node as a merge candidate with itself in the second pass, and so it incorrectly determines a merge should occur.)

f82d7d1 Mengdong Lin 22 September 2013, 00:34:45 UTC ALSA : hda - not use assigned converters for all unused pins BIOS can mark a pin as "no physical connection" if the port is used by an integrated display which is not audio capable. And audio driver will overlook such pins. On Haswell, such a disconneted pin will keep muted and connected to the 1st converter by default. But if the 1st convertor is assigned to a connected pin for audio streaming. The muted disconnected pin can make the connected pin no sound output. So this patch avoids using assigned converters for all unused pins for Haswell, including the disconected pins.

831abf7 Kurt Garloff 24 September 2013, 12:13:48 UTC usb/core/devio.c: Don't reject control message to endpoint with wrong direction bit Trying to read data from the Pegasus Technologies NoteTaker (0e20:0101) [1] with the Windows App (EasyNote) works natively but fails when Windows is running under KVM (and the USB device handed to KVM). The reason is a USB control message usb 4-2.2: control urb: bRequestType=22 bRequest=09 wValue=0200 wIndex=0001 wLength=0008 This goes to endpoint address 0x01 (wIndex); however, endpoint address 0x01 does not exist. There is an endpoint 0x81 though (same number, but other direction); the app may have meant that endpoint instead. The kernel thus rejects the IO and thus we see the failure. Apparently, Linux is more strict here than Windows ... we can't change the Win app easily, so that's a problem. It seems that the Win app/driver is buggy here and the driver does not behave fully according to the USB HID class spec that it claims to belong to. The device seems to happily deal with that though (and seems to not really care about this value much). So the question is whether the Linux kernel should filter here. Rejecting has the risk that somewhat non-compliant userspace apps/ drivers (most likely in a virtual machine) are prevented from working. Not rejecting has the risk of confusing an overly sensitive device with such a transfer. Given the fact that Windows does not filter it makes this risk rather small though. The patch makes the kernel more tolerant: If the endpoint address in wIndex does not exist, but an endpoint with toggled direction bit does, it will let the transfer through. (It does NOT change the message.) With attached patch, the app in Windows in KVM works. usb 4-2.2: check_ctrlrecip: process 13073 (qemu-kvm) requesting ep 01 but needs 81 I suspect this will mostly affect apps in virtual environments; as on Linux the apps would have been adapted to the stricter handling of the kernel.

5df718d Tomasz Figa 25 September 2013, 10:00:59 UTC clocksource: exynos_mct: Set IRQ affinity when the CPU goes online Some variants of Exynos MCT, namely exynos4210-mct at the moment, use normal, shared interrupts for local timers. This means that each interrupt must have correct affinity set to fire only on CPU corresponding to given local timer. However after recent conversion of clocksource drivers to not use the local timer API for local timer initialization any more, the point of time when local timers get initialized changed and irq_set_affinity() fails because the CPU is not marked as online yet. This patch fixes this by moving the call to irq_set_affinity() to CPU_ONLINE notification, so the affinity is being set when the CPU goes online. This fixes a regression introduced by commit ee98d27df6 ARM: EXYNOS4: Divorce mct from local timer API which rendered all Exynos4210 based boards unbootable due to failing irq_set_affinity() making local timers inoperatible.

a869342 Alan Stern 24 September 2013, 19:46:45 UTC USB: OHCI: accept very late isochronous URBs Commit 24f531371de1 (USB: EHCI: accept very late isochronous URBs) changed the isochronous API provided by ehci-hcd. URBs submitted too late, so that the time slots for all their packets have already expired, are no longer rejected outright. Instead the submission is accepted, and the URB completes normally with a -EXDEV error for each packet. This is what client drivers expect. This patch implements the same policy in ohci-hcd. The change is more complicated than it was in ehci-hcd, because ohci-hcd doesn't scan for isochronous completions in the same way as ehci-hcd does. Rather, it depends on the hardware adding completed TDs to a "done queue". Some OHCI controller don't handle this properly when a TD's time slot has already expired, so we have to avoid adding such TDs to the schedule in the first place. As a result, if the URB was submitted too late then none of its TDs will get put on the schedule, so none of them will end up on the done queue, so the driver will never realize that the URB should be completed. To solve this problem, the patch adds one to urb_priv->td_cnt for such URBs, making it larger than urb_priv->length (td_cnt already gets set to the number of TD's that had to be skipped because their slots have expired). Each time an URB is given back, the finish_urb() routine looks to see if urb_priv->td_cnt for the next URB on the same endpoint is marked in this way. If so, it gives back the next URB right away. This should be applied to all kernels containing commit 815fa7b91761 (USB: OHCI: fix logic for scheduling isochronous URBs).

Hi Greg, Here's five bug fixes for 3.12. The first two bugs fix issues with the command cancellation handling, which can lead to oopses or the xHCI driver attempting to handle previously-completed transfers. People have been running into oopses and odd behavior with command cancellation for a couple kernel releases, so they're marked for stable. The third patch fixes an issue with USB remote wakeup under xHCI that can only be reproduced under ChromeOS. As discussed, this fix is not urgent, and isn't marked for stable. The fourth patch fixes a race condition between URB cancellation and userspace clearing an endpoint stall. The fifth patch removes some annoying dmesg spam when a USB 3.0 device is disconnected, by avoiding sending a Set SEL request. Sarah Sharp 26 September 2013, 00:01:47 UTC
