This also causes these interrupts to not be able to abort suspend (via check_wakeup_irqs() in late suspend.) Currently, we don't implement ->irq_set_wake() for INTC interrupts because they default to be wakeup enabled by setting the GRPSEL bits in PM init. Even though there is no ->irq_set_wake(), we want enable_irq_wake() to succeed so these interrupts can abort suspend when necessary. To fix, set IRQCHIP_SKIP_SET_WAKE flag for all the INTC interrupts which avoids trying to check irq_chip->irq_set_wake() and failing when it doesn't exist. Longer term, we need to implement ->irq_set_wake() for the INTC which can manage the appropriate GRPSEL bits.

For PRCM interrupts, we may want to avoid that until the PM core code is fully ready to handle the interrupts. This is particularily true for IO pad interrupts on OMAP3, which are shared between the hwmod core and the PRM core. In order to avoid PRCM IO-chain interrupts until the PM core is ready to handle them, ready, set the IRQ_NOAUTOEN flag for the PRCM IO-chain interrupt, which means it will remain disabled after request_irq(). Then, explicitly enable the PRCM interrupts after the request_irq() in the PM core (but not in the hwmod core.) Special thanks to Tero Kristo for suggesting to isolate the fix to only the IO-chain interrupt on OMAP3 instead of all PRCM interrupts.

Unfortunately, on other omap SoCs, a 0 bit means a feature is "Full Use" so the OMAP3_CHECK_FEATURE() macro called by omap3_check_features() will incorrectly interpret those zeroes to mean that a feature is present even though it isn't. To fix that, the feature bits that are incorrectly set (namely, OMAP3_HAS_IVA and OMAP3_HAS_ISP) need to be cleared after all of the calls to OMAP3_CHECK_FEATURE() in omap3_check_features() are made.

All of the bind_XYZ_to_irq do a quick lookup to see if the event exists. And if it does, then the initialized IRQ number is returned instead of initializing a new IRQ number. This patch adds an extra logic to check that the type returned is proper one and that there is an IRQ handler setup for it.

As such we would did not subtract from xen_released_pages the count of pages that we had populated back (instead we just did a simple extra_pages = released - populated). The balloon driver uses xen_released_pages to set the initial current_pages count. If this is wrong (too low) then when a new (higher) target is set, the balloon driver will request too many pages from Xen."

Access to the MSRs is however redirected to the currently scheduled physical CPU, making consecutive read and compares unreliable. In addition each rdmsr traps into the hypervisor. So to avoid bogus readouts and expensive traps, disable the kernel internal feature flag for APERF/MPERF if running under Xen. This will a) remove the aperfmperf flag from /proc/cpuinfo b) not mislead the power scheduler (arch/x86/kernel/cpu/sched.c) to use the feature to improve scheduling (by default disabled) c) not mislead the cpufreq driver to use the MSRs This does not cover userland programs which access the MSRs via the device file interface, but this will be addressed separately.

This is not correct, for certain frequencies after setting a frequency with set_rate, recalc_rate will return different values. To fix this, introduce set_rate/recalc_rate functions which work on variables instead of registers directly. This way we can call these in round_rate to get the exact rate which we would get if we call set_rate with this value.

This means that we can up calling iio_dev_release after iio_device_free which will lead to a use after free. As the general rule the struct containing the device should always be freed in the release callback. This is what this patch does, it moves freeing the iio device struct as well as releasing the idr reference to the release callback. To ensure that the device is not freed before calling iio_device_free the device_unregister call in iio_device_unregister is broken apart. iio_device_unregister will now only call device_del to remove the device from the system and iio_device_free will call put_device to drop the reference we obtained in iio_devce_alloc. We also have to take care that calling iio_device_free without having called iio_device_register still works (i.e. this can happen if something failed during device initialization). For this to work properly two minor changes were necessary: channel_attr_list needs to be initialized in iio_device_alloc and we have to check whether the chrdev has been registered before releasing it in iio_device_release. This change also brings iio_device_unregister and iio_device_free more in sync with iio_device_register and iio_device_alloc which call device_add and device_initialize respectively.

If uart pads were used in different mode by any other module then it would fail since the default pads took over all the uart pins forcefully. With removal of default pads the rx_pad wakeup for console uart while waking up from off mode is broken. Utilise the mux api available to probe the availability of mux pins in uart mode and probe for availability of uart pin in mux mode0 if uart is available as uart pin itself then configure rx pin as wakeup capable. This patch itself doesn't cater to all boards. Boards using uart rx wakeup mechanism should ensure the usage of omap_serial_init_port by configuring required uart ports and pass necessary mux data, till then this probing of uart pins can cater to enabling of rx pad wakeup to most of the boards. This patch can also throw some boot warning from _omap_mux_get_by_name if pin is requested for availability is not present while dynamically probing the uart pins availability such boot warnings can be addressed only when board files are patched with omap_serial_init_port calls passing the right pads needed for a given port.

The problem is that encode_getfattr_open() will still request an mdsthreshold, and so we end up Oopsing in decode_attr_mdsthreshold. This patch fixes encode_getfattr_open so that it doesn't request an mdsthreshold when the caller isn't asking for one. It also fixes decode_attr_mdsthreshold so that it errors if the server returns an mdsthreshold that we didn't ask for (instead of Oopsing).

McKenney" Date: Thu, 10 May 2012 16:41:44 -0700 Subject: [PATCH 083/504] rcu: Precompute RCU_FAST_NO_HZ timer offsets When a CPU is entering dyntick-idle mode, tick_nohz_stop_sched_tick() calls rcu_needs_cpu() see if RCU needs that CPU, and, if not, computes the next wakeup time based on the timer wheels. Only later, when actually entering the idle loop, rcu_prepare_for_idle() will be invoked. In some cases, rcu_prepare_for_idle() will post timers to wake the CPU back up. But all for naught: The next wakeup time for the CPU has already been computed, and posting a timer afterwards does not force that wakeup time to be recomputed. This means that rcu_prepare_for_idle()'s have no effect. This is not a problem on a busy system because something else will wake up the CPU soon enough. However, on lightly loaded systems, the CPU might stay asleep for a considerable length of time. If that CPU has a callback that the rest of the system is waiting on, the system might run very slowly or (in theory) even hang. This commit avoids this problem by having rcu_needs_cpu() give tick_nohz_stop_sched_tick() an estimate of when RCU will need the CPU to wake back up, which tick_nohz_stop_sched_tick() takes into account when programming the CPU's wakeup time. An alternative approach is for rcu_prepare_for_idle() to use hrtimers instead of normal timers, but timers are much more efficient than are hrtimers for frequently and repeatedly posting and cancelling a given timer, which is exactly what RCU_FAST_NO_HZ does.

It turns out that the issue is caused by coherency of the cpu that is being shut down. When shutting down a cpu, we need to have the cpu exit coherency to prevent it from receiving cache, TLB, or BTB maintenance operations broadcast by other CPUs in the cluster. Copy cpu_enter_lowpower() and cpu_leave_lowpower() from mach-vexpress to have coherency properly handled in platform_cpu_die(), thus fix the issue.

Without this reversion, any page that is sent to commit holds on to an unbalanced reference that is never freed. The immediate effect is an imbalance over the wire between OPENs and CLOSEs.

It would default to writing to file descriptor 0, i.e., stdin. Writing to stdin is allowed and is equivalent to writing to stdout. However, there is a major difference for any script that was already capturing the output of perf stat via redirection: perf stat >/tmp/log .... or perf stat 2>/tmp/log .... They would not capture anything anymore. They would have to do: perf stat 0>/tmp/log ... This breaks compatibility with existing scripts and does not look very natural. This patch fixes the problem by looking at output_fd only when it was modified by user (> 0). It also checks that the value if positive. Passing --log-fd 0 is ignored. I would also argue that defaulting to stderr for the results is not the right thing to do, though this patch does not address this specific issue.

But in current notifier_chain implementation logic, it doesn't accept same notifier registered twice. If so, it will be wrong when adding/removing the element from the list. For example, on one SandyBridge platform, remove module sb_edac and then trigger one error, it will hit oops because it has no mce decoder registered but related notifier_chain still points to an invalid callback function.

Meaning that the module which was using it could be rmmod-ed while the device is open, and then BAD things happen. I know, as I found out the hard way :) Note that there is no need to also somehow increase the refcount of the snd-tea575x-tuner module itself, since any drivers using it will have symbolic references to it.

The msp3410 can handle this fine, but it is a bit weird compared to how it is handled on other boards.

Hopefully this works for all clients. Platform callbacks are bad for device tree migration anyway, so this rids us of another problem in Ux500.

Since the only time we remove entries from this map is when we free a session, this means that if we later delete this node ACL without the initiator ever creating a session, we'll leave the nacl pointer in the btree pointing at freed memory. This is especially bad if that initiator later does send us a command that would cause us to create a dynamic ACL and session: we'll find the stale freed nacl pointer in the btree and end up with use-after-free. We could add more code to clear the btree entry when deleting the explicit nacl, but the original insertion is pointless: without a session attached, we'll just have to update the entry when a session appears anyway. So we can just delete tcm_qla2xxx_setup_nacl_from_rport() and the code that calls it.

Users have been forced to unbind or unload ehci-hcd before putting their systems to sleep. After extensive testing, it was determined that the machines don't like going into suspend when any EHCI controllers are in the PCI D3 power state. Presumably this is a firmware bug, but there's nothing we can do about it except to avoid putting the controllers in D3 during system sleep. The patch adds a new flag to indicate whether the problem is present, and avoids changing the controller's power state if the flag is set. Runtime suspend is unaffected; this matters only for system suspend. However as a side effect, the controller will not respond to remote wakeup requests while the system is asleep. Hence USB wakeup is not functional -- but of course, this is already true in the current state of affairs. A similar patch has already been applied as commit 151b61284776be2d6f02d48c23c3625678960b97 (USB: EHCI: fix crash during suspend on ASUS computers). The patch supersedes that one and reverts it. There are two differences: The old patch added the flag at the USB level; this patch adds it at the PCI level. The old patch applied to all chipsets with the same vendor, subsystem vendor, and product IDs; this patch makes an exception for a known-good system (based on DMI information).

This can lead to problems: The driver can end up getting bound to a USB interface without being allowed to bind to the corresponding serial port. This patch (as1557) fixes the problem by using the same device ID table (the one that can be altered by the "vendor=" and "product=" module parameters) for both purposes. The unused table is removed. Now the driver will bind only to the intended devices.

Two bits are used to enable this operation: Save State and Restore State. xHCI spec 4.23.2 says software should "Set the Controller Save/Restore State flag in the USBCMD register and wait for the Save/Restore State Status flag in the USBSTS register to transition to '0'". However, it does not define how long software should wait for the SSS/RSS bit to transition to 0. Currently the timeout is set to 1ms. There is bug report (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1002697) indicates that the timeout is too short for ASMedia ASM1042 host controller to save/restore the state successfully. Increase the timeout to 10ms helps to resolve the issue.

This is done with the pl330_lock held. Then, it iterates through the req_done list, calling the callback for each of the requests that are done. The problem is that the driver releases the lock before calling the callback for each of the callbacks. pl330_submit_req() running in another processor can then acquire the lock and insert another request in one of the thrd->req that hasn't been processed yet, replacing the pointer to pl330_req there. When the callback returns in pl330_update() and the next rqdone is popped from the list, it dereferences the pl330_req pointer to the just scheduled pl330_req, instead of the one that has finished, calling pl330 with the wrong r. This patch fixes this by storing the pointer to pl330_req directly in the list.

This is my attempt to quiet them down and keep it less confusing for the end user. What I did is print the message for cpu0 and save it for future comparisons.

This obviously didn't give the correct result. This commit adds btrfs_next_old_leaf, a drop-in replacement for btrfs_next_leaf with a time_seq parameter. If it is zero, it behaves exactly like btrfs_next_leaf. If it is non-zero, it will use btrfs_search_old_slot with this time_seq parameter.

A simplified call graph looks like this: pygrub QEMU ----------------------------------------------- do_read_cache_page io_submit | | lock_page ext3_direct_IO | bio_add_page | lock_page Internally the xen-blkback uses m2p_add_override to swizzle (temporarily) a 'struct page' to have a different MFN (so that it can point to another guest). It also can easily find out whether another pfn corresponding to the mfn exists in the m2p, and can set the FOREIGN bit in the p2m, making sure that mfn_to_pfn returns the pfn of the backend. This allows the backend to perform direct_IO on these pages, but as a side effect prevents the frontend from using get_user_pages_fast on them while they are being shared with the backend.

The problem here is that the loop variable is taken for the interface number in the comparison logic that gathers the association. Which is fine as long as the descriptors are sane. In the case above, however, the logic gets out of sync and the interface association fields of all interfaces beyond the interface number gap are wrong.

Instead of adding locking around all of this he suggested doing it with RCU, so I've introduced a struct rcu_string that does just that and have gone through and protected all accesses to device->name that aren't under the uuid_mutex with rcu_read_lock(). This protects us and I will use it for dealing with removing the device that we used to mount the file system in a later patch.

So if there are multiple devices in a btrfs file system we will just print the device with the lowest devid that we can find. This will make everything consistent and deal with device removal properly. The drawback is if you mount with a device that is higher than the lowest devicd it won't show up as the mounted device in /proc/mounts, but this is a small price to pay.

This is because when writing out an inode under compression we immediately return without actually doing anything to the pages, and then in another thread at some point down the line actually do the ordered dance. The problem is between the point that we start writeback and we actually add the ordered extent we could be trying to reclaim the inode, which makes igrab() return NULL. So we need to do an igrab() when we create the async extent and then drop it when we are done with it. This makes sure we stay pinned in memory until the ordered extent can get a reference on it and we are good to go. With this patch we no longer panic in btrfs_finish_ordered_io().

Because compression can return from filemap_fdatawrite() without having actually set any of it's pages as writeback() it can make filemap_fdatawait() do essentially nothing, and then we won't find any ordered extents because they may not have been created yet. So not only does this make fsync() completely useless, but it will also screw up if you truncate on a non-page aligned offset since we zero out the end and then wait on ordered extents and then call drop caches. We can drop the cache before the io completes and then we try to unpin the extent we just wrote we won't find it and everything goes sideways. So fix this by putting it back and put a giant comment there to keep me from trying to remove it in the future.

This bug was introduced by commit 17ce6ef8d731af5edac8c39e806db4c7e1f6956f ("Btrfs: add a check to decide if we should defrag the range") The cause is, that commit looked into previous and next extents using lookup_extent_mapping() only. While at it, remove the code that checks the previous extent, since it's sufficient to check the next extent.

Whoops. Yes, I blindly followed read_swap_header()'s pte_to_swp_entry( swp_entry_to_pte()) technique for determining maximum usable swap offset, without stopping to realize that that actually depends upon the pte swap encoding shifting swap offset to the higher bits and truncating it there. Whereas our radix_tree swap encoding leaves offset in the lower bits: it's swap "type" (that is, index of swap area) that was truncated. Fix it by reducing the SWP_TYPE_SHIFT() in swapops.h, and removing the broken radix_to_swp_entry(swp_to_radix_entry()) from read_swap_header(). This does not reduce the usable size of a swap area any further, it leaves it as claimed when making the original commit: no change from 3.0 on x86_64, nor on i386 without PAE; but 3.0's 512GB is reduced to 128GB per swapfile on i386 with PAE. It's not a change I would have risked five years ago, but with x86_64 supported for ten years, I believe it's appropriate now. Hmm, and what if some architecture implements its swap pte with offset encoded below type? That would equally break the maximum usable swap offset check.

This commit prevents a DP screen from properly training the link. Oddly enough it works, once the machine has been warm-booted with an older kernel. According to DP docs this _should_ have been the right precharge time. Also, the commit that originally introduces this was just general snb DP enabling and didn't mention any specific reason for this special value.

Say we have two processes A and B, and let syslog_seq = N, while log_next_seq = N + 1, and the two processes both come to syslog_print at almost the same time. And No matter which process get the spin lock first, it will increase syslog_seq by one, then release spin lock; thus later, another process increase syslog_seq by one again. In this case, syslog_seq is bigger than syslog_next_seq. And latter, it would make: wait_event_interruptiable(log_wait, syslog != log_next_seq) don't wait any more even there is no new write comes. Thus it introduce a infinite loop reading. I can easily see this kind of issue by the following steps: # cat /proc/kmsg # at meantime, I don't kill rsyslog # So they are the two processes. # xinit # I added drm.debug=6 in the kernel parameter line, # so that it will produce lots of message and let that # issue happen It's 100% reproducable on my side. And my disk will be filled up by /var/log/messages in a quite short time. So, introduce a mutex_lock to stop syslog_seq from going wild just like what devkmsg_read() does.

This patch fixes that and prepares for further I/O space clean-up. I/O space handling on the versatile platform is currently broken in multiple ways. Most importantly, the ports do not get mapped into the virtual address space at all. Also, there is some amount of confusion between PCI I/O space and other statically mapped MMIO registers in the platform code: * The __io_address() macro that is used to access the platform register maps to the same __io macro that gets used for I/O space. * The IO_SPACE_LIMIT is set to a value that is much larger than the total available space. * The I/O resource of the PCI bus is set to the physical address of the mapping, which is way outside of the actual I/O space limit as well as the address range that gets decoded by traditional PCI cards. * No attempt is made to stay outside of the ISA port range that some device drivers try access. * No resource gets requested as a child of ioport_resource, but an IORESOURCE_IO type mapping gets requested as a child of iomem_resource. This patch attempts to correct all of the above. This makes it possible to use virtio-pci based virtual devices as well as actual PCI cards including those with legacy ISA port ranges like VGA. Some of the issues seem to be duplicated on other platforms.

At boot the ethernet clks are unused, so get turned off. Later, when the module is loaded, the probe function would access the hardware before the clock was restarted, and the machine would lock. It has also been determined that when the clk is turned off, the interface forgets its MAC address, which for most systems, is set by the boot loader. When the machine setup file creates a platform device for the interface, prepare and enable the clock for the interface. This will ensure it is not turned off. However, if the setup file only instantiates one platform device, the other will have its clk disabled, thus maybe saving a little power.

This addresses an issue encountered when a pcm is opened while transitioning to low power state (codec->power_on == 1 && codec->power_transition == -1). Add snd_pcm_power_up_d3wait to hda_codec. This function is used to power up from azx_open as opposed to snd_hda_power_up used from codec_exec_verb. When powering up from azx_open, wait for pending power downs to complete, avoiding the power up continuing in parallel with the power down on the work queue. The specific issue seen was with the CS4210 codec, it powers off the ADC and DAC nid in its suspend handler. If it is re-opened before the ~100ms power down process completes, the ADC and DAC nid are initialized while powered down and audio is lost until another suspend/resume cycle.

However, if the associated directory is open at the time, the dentry ref count is non-zero. If the fd for this directory is then passed into perf_event_open, it does a css_get(). This bounces the ref count back up from zero. This is a problem by itself. But what makes it turn into a crash is the fact that we end up doing an extra dput, since we perform a dput when css_put sees the ref count go down to zero. css_tryget() does not fall into that trap. So, we use that instead.

The nfs_match_client() reference from nfs4_set_ds_client bumps the cl_count, the nfs_client is not freed at umount, and nfs4_deviceid_purge_client is not called to dereference the MDS usage of a deviceid which holds a reference to the DS nfs_client. The result is the umount program returns, but the nfs_client is not freed, and the cl_session hearbeat continues. The MDS (and all other nfs mounts) lose their last nfs_client reference in nfs_free_server when the last nfs_server (fsid) is umounted. The file layout DS lose their last nfs_client reference in destroy_ds when the last deviceid referencing the data server is put and destroy_ds is called. This is triggered by a call to nfs4_deviceid_purge_client which removes references to a pNFS deviceid used by an MDS mount. The fix is to track how many pnfs enabled filesystems are mounted from this server, and then to purge the device id cache once that count reaches zero.

The idea is, before calling the lockdep code, do a load_idt() to the special IDT that kept the breakpoint stack from reseting. This worked well as a quick fix for this kernel release, until a certain config caused a lockup in the function tracer start up tests. Investigating it, I found that the load_idt that was used to prevent the int3 from changing stacks was itself being traced! Even though the config had CONFIG_OPTIMIZE_INLINING disabled, and all 'inline' tags were set to always inline, there were still cases that it did not inline! This was caused by CONFIG_PARAVIRT_GUEST, where it would add a pointer to the native_load_idt() which made that function to be traced. Commit 45959ee7aa645815a ("ftrace: Do not function trace inlined functions") only touched the 'inline' tags when CONFIG_OPMITIZE_INLINING was enabled. PARAVIRT_GUEST shows that this was not enough and we need to also mark always_inline with notrace as well.

This is not good, since kvmppc_pin_guest_page() calls down_read() and get_user_pages_fast(), both of which can sleep. This bug was introduced in 2e25aa5f ("KVM: PPC: Book3S HV: Make virtual processor area registration more robust"). This arranges to drop those spinlocks before calling kvmppc_pin_guest_page() and re-take them afterwards. Dropping the vcore lock in kvmppc_run_core() means we have to set the vcore_state field to VCORE_RUNNING before we drop the lock, so that other vcpus won't try to run this vcore.

The purpose of the ->get and ->put methods in a ceph connection are to allow the connection to indicate it has a reference to something external to the messaging system, *not* to indicate something external has a reference to the connection.

One gpio_request_one(powerdown-gpio, ...) was mistakenly left unremoved in the Beagle board file. This causes the tfp410 driver to fail to request the gpio on Beagle, causing the driver to fail and thus the DVI output doesn't work. This patch removes several boot errors from board-omap3beagle.c: - gpio_request: gpio--22 (DVI reset) status -22 - Unable to get DVI reset GPIO There is a combination of leftover code and revision confusion. Additionally, xM support is currently a hack. For original Beagleboard this removes the double initialization of GPIO 170, properly configures it as an output, and wraps the initialization in an if block so that xM does not attempt to request it. For Beagleboard xM it removes reference to GPIO 129 which was part of rev A1 and A2 designs, but never functioned. It then properly assigns beagle_dvi_device.reset_gpio in beagle_twl_gpio_setup and removes the hack of initializing it high. Additionally, it uses gpio_set_value_cansleep since this GPIO is connected through i2c. Unfortunately, there is no way to tell the difference between xM A2 and A3. However, GPIO 129 does not function on rev A1 and A2, and the TWL GPIO used on A3 and beyond is not used on rev A1 and A2, there are no problems created by this fix. Tested on Beagleboard-xM Rev C1 and Beagleboard Rev B4.

If a we have multi-block page for which an unwritten extent has been allocated, and only some of the buffers have been written to, and they are not contiguous, we can expose stale data from disk in the blocks between the writes after extent conversion. Example of a page with unwritten and real data. buffer content 0 empty b_state = 0 1 DATA b_state = 0x1023 Uptodate,Dirty,Mapped,Unwritten 2 DATA b_state = 0x1023 Uptodate,Dirty,Mapped,Unwritten 3 empty b_state = 0 4 empty b_state = 0 5 DATA b_state = 0x1023 Uptodate,Dirty,Mapped,Unwritten 6 DATA b_state = 0x1023 Uptodate,Dirty,Mapped,Unwritten 7 empty b_state = 0 Buffers 1, 2, 5, and 6 have been written to, leaving 0, 3, 4, and 7 empty. Currently buffers 1, 2, 5, and 6 are added to a single ioend, and when IO has completed, extent conversion creates a real extent from block 1 through block 6, leaving 0 and 7 unwritten. However buffers 3 and 4 were not written to disk, so stale data is exposed from those blocks on a subsequent read. Fix this by setting iomap_valid = 0 when we find a buffer that is not Uptodate. This ensures that buffers 5 and 6 are not added to the same ioend as buffers 1 and 2. Later these blocks will be converted into two separate real extents, leaving the blocks in between unwritten.

So instead of dealing only with "consistent" pmdvals in pmd_none_or_trans_huge_or_clear_bad() (which would be conceptually simpler) we let pmd_none_or_trans_huge_or_clear_bad() deal with pmdvals where the low 32bit and high 32bit could be inconsistent (to avoid having to use cmpxchg8b). The only guarantee we get from pmd_read_atomic is that if the low part of the pmd was found null, the high part will be null too (so the pmd will be considered unstable). And if the low part of the pmd is found "stable" later, then it means the whole pmd was read atomically (because after a pmd is stable, neither MADV_DONTNEED nor page faults can alter it anymore, and we read the high part after the low part). In the 32bit PAE x86 case, it is enough to read the low part of the pmdval atomically to declare the pmd as "stable" and that's true for THP and no THP, furthermore in the THP case we also have a barrier() that will prevent any inconsistent pmdvals to be cached by a later re-read of the *pmd.

Block caches of gc-inodes must be cleared every time a garbage collection function (nilfs_clean_segments) completes. Otherwise, stale blocks buffered in the caches may be wrongly reused in successive calls of the GC function. For user files, this is not a problem because their gc-inodes are distinguished by a checkpoint number as well as an inode number. They never buffer different blocks if either an inode number, a checkpoint number, or a block offset differs. However, gc-inodes of sufile, cpfile and DAT file can store different data for the same block offset. Thus, the nilfs_clean_segments function can move incorrect block for these meta-data files if an old block is cached. I found this is really causing meta-data corruption in nilfs. This fixes the issue by ensuring cache clear of gc-inodes and resolves reported GC problems including checkpoint file corruption, b-tree corruption, and the following warning during GC. nilfs_palloc_freev: entry number 307234 already freed. ...

Biederman" Date: Wed, 20 Jun 2012 12:53:03 -0700 Subject: [PATCH 389/504] pidns: guarantee that the pidns init will be the last pidns process reaped Today we have a twofold bug. Sometimes release_task on pid == 1 in a pid namespace can run before other processes in a pid namespace have had release task called. With the result that pid_ns_release_proc can be called before the last proc_flus_task() is done using upid->ns->proc_mnt, resulting in the use of a stale pointer. This same set of circumstances can lead to waitpid(...) returning for a processes started with clone(CLONE_NEWPID) before the every process in the pid namespace has actually exited. To fix this modify zap_pid_ns_processess wait until all other processes in the pid namespace have exited, even EXIT_DEAD zombies. The delay_group_leader and related tests ensure that the thread gruop leader will be the last thread of a process group to be reaped, or to become EXIT_DEAD and self reap. With the change to zap_pid_ns_processes we get the guarantee that pid == 1 in a pid namespace will be the last task that release_task is called on. With pid == 1 being the last task to pass through release_task pid_ns_release_proc can no longer be called too early nor can wait return before all of the EXIT_DEAD tasks in a pid namespace have exited.

The original reason has gone away after the previous patch, ->children list must be empty after zap_pid_ns_processes(). However now we can not switch to init_pid_ns.child_reaper. __unhash_process() relies on the "->child_reaper == parent" check, but this check does not work if the last exiting task is also the child reaper. As Eric sugested, we can change __unhash_process() to use the parent's pid_ns and remove this code. Also, with this change we can move detach_pid(PIDTYPE_PID) back, where it was before the previous fix. Signed-off-by: Oleg Nesterov Acked-by: "Eric W.

If the reserved region array lacks space for the new range, memblock_double_array() is called to allocate more space for the array. If memblock is used to allocate memory for the new array it can end up using a range that overlaps with the range originally allocated in __alloc_memory_core_early(), leading to possible data corruption. With this patch memblock_double_array() now calls memblock_find_in_range() with a narrowed candidate range (in cases where the reserved.regions array is being doubled) so any memory allocated will not overlap with the original range that was being reserved. The range is narrowed by passing in the starting address and size of the previously allocated range. Then the range above the ending address is searched and if a candidate is not found, the range below the starting address is searched.

The problem is that xfs_buf_alloc() sets b_bn to -1 and thus effectively every buffer is straddling a page boundary which causes xfs_buf_allocate_memory() to allocate two pages and use vmalloc() for access which is unnecessary. Dave says xfs_buf_alloc() doesn't need to set b_bn to -1 anymore since the buffer is inserted into the cache only after being fully initialized now. So just make xfs_buf_alloc() fill in proper block number from the beginning.

This causes the first packet with sequence number 0 being dropped. Initialize rx sequence number as 0xffff and skip adjusting start_win if the sequence number remains 0xffff. The sequence number will be updated once the first packet is received.

The eapol packet should be sent directly without 11n aggregation. This patch fixes the problem by adding WPS session control while dequeuing Tx packets for transmission.

Still, we have reports of this being seen in the wild. Now Bspec has this little bit of lovely language in the PMIIR register: Public SNB Docs, Vol3Part2, 2.5.14 "PMIIR": "For each bit, the IIR can store a second pending interrupt if two or more of the same interrupt conditions occur before the first condition is cleared. Upon clearing the interrupt, the IIR bit will momentarily go low, then return high to indicate there is another interrupt pending." Now if we presume that PMIMR only prevent new interrupts from being queued, we could easily end up masking an interrupt and clearing it, but the 2nd pending interrupt setting the bit in PMIIR right away again. Which leads, the next time the irq handler runs, to hitting the WARN. Also, no bad side effects of this have ever been reported. And we've tracked down our issues with the gpu turbo getting stuck to bogus interrupt generation limits in th RPLIMIT register. So let's just rip out this WARN as bogus and call it a day. The only shallow thing here is that this 2-deep irq queue in the hw makes you wonder how racy the windows irq handler is ...

They report bogus sizes, in some cases becoming unusable as a result. The bugs were triggered by commit 09b6b51b0b6c1b9bb61815baf205e4d74c89ff04 (SCSI & usb-storage: add flags for VPD pages and REPORT LUNS), which caused usb-storage to stop overriding the SCSI level reported by devices. By default, the sd driver will try READ CAPACITY(16) first for any device whose level is above SCSI_SPC_2. It seems likely that any device large enough to require the use of READ CAPACITY(16) (i.e., 2 TB or more) would be able to handle READ CAPACITY(10) commands properly. Indeed, I don't know of any devices that don't handle READ CAPACITY(10) properly. Therefore this patch (as1559) adds a new flag telling the sd driver to try READ CAPACITY(10) before READ CAPACITY(16), and sets this flag for every USB mass-storage device. If a device really is larger than 2 TB, sd will fall back to READ CAPACITY(16) just as it used to. This fixes Bugzilla #43391. Signed-off-by: Alan Stern Acked-by: Hans de Goede CC: "James E.J.

All Orion based systems have 1Mbyte of IO space per PCI[e] bus, and try to request_resource() this size. Orion5x has two such PCI buses. It is likely that the original, removed version, was broken. This version might be less broken. However, it has not been tested on hardware with a PCI card, let alone hardware with a PCI card with IO capabilities.

However current code, due to a subtle bug, allocated those chunks in the smallest-to-largest order, what completely killed all the advantages of using larger than page chunks. If a 4KiB chunk has been mapped as a first chunk, the consecutive chunks are not aligned correctly to the power-of-two which match their size and IOMMU drivers were not able to use internal mappings of size other than the 4KiB (largest common denominator of alignment and chunk size).

Commit 2603efa31a03 ("bug.h: Fix up powerpc build regression") corrected the powerpc build case and extended the __ASSEMBLY__ guards, but it also got caught in pre-processor hell accidentally matching the else case of CONFIG_BUG resulting in the BUG disabled case tripping up on -Werror=implicit-function-declaration. It's not possible to __ASSEMBLY__ guard the entire file as architecture code needs to get at the BUGFLAG_WARNING definition in the GENERIC_BUG case, but the rest of the CONFIG_BUG=y/n case needs to be guarded. Rather than littering endless __ASSEMBLY__ checks in each of the if/else cases we just move the BUGFLAG definitions up under their own GENERIC_BUG test and then shove everything else under one big __ASSEMBLY__ guard. Build tested on all of x86 CONFIG_BUG=y, CONFIG_BUG=n, powerpc (due to it's dependence on BUGFLAG definitions in assembly code), and sh (due to not bringing in linux/kernel.h to satisfy the taint flag definitions used by the generic bug code). Hopefully that's the end of the corner cases and I can abstain from ever having to touch this infernal header ever again.

This caused a regression when using WEP-LEAP. This patch fixes the regression by keeping track of which key indexes refer to CCMP keys and only using the key miss indication for those.

The breakage example seen is on GTX 560Ti, with a pciid of 0x1200, which gets detected as an NV20 (0x020x) with 1 CRTC by nv_two_heads(), causing memory corruption because there's actually 2 CRTCs.. This switches fbcon to use the CRTC count directly from the mode_config structure, which will also fix the same issue on Kepler boards which have 4 CRTCs.

But mmc_sd_num_wr_blocks() function which sends the ACMD22 calculates the data timeout value from csd.tacc_ns and csd.tacc_clks parameters which will be 0 for block addressed (>2GB cards) SD card. This would result in timeout_ns and timeout_clks being 0 in the mmc_request passed to host driver. This means host controller would program its data timeout timer value with 0 which could result in DATA TIMEOUT errors from controller. To fix this issue, mmc_sd_num_wr_blocks() should instead just call the mmc_set_data_timeout() to calculate the data timeout value. mmc_set_data_timeout() function ensures that non zero timeout value is set even for block addressed SD cards.

After bisecting, this commit dba3c29 is found to ruin micro-SD card data (writing incorrect file, or fs is corrupt after several times mount) on the beagle-xm revB, and reverting the commit will fix the problem. Also from TRM of OMAP3/OMAP4/DM37x, the below is mentioned about the Auto CMD12 Enable bit. - SDIO does not support this feature. - SD card only. Looks it is not suitable to always enable Auto CMD12 in host controller driver. Considered that the commit is not mature enough, so ask to revert it first.

This was resulting in the FCoE DDP logic having issues since it thought the frame still had data in it due to the padding.
