2013-07-21UBIFS: correct mount messageRichard Genoud
commit beadadfa5467e09e36891f39cae1f5d8d3bbf17e upstream. When mounting an UBIFS R/W volume, we have the message: UBIFS: mounted UBI device 0, volume 1, name "rootfs"(null) With this patch, we'll have: UBIFS: mounted UBI device 0, volume 1, name "rootfs" Which is, I think, what was intended.

2013-07-21mm/memory-hotplug: fix lowmem count overflow when offline pagesWanpeng Li
commit cea27eb2a202959783f81254c48c250ddd80e129 upstream. The logic for the memory-remove code fails to correctly account the Total High Memory when a memory block which contains High Memory is offlined as shown in the example below. The following patch fixes it.

2013-07-21memcg, kmem: fix reference count handling on the error pathMichal Hocko
commit f37a96914d1aea10fed8d9af10251f0b9caea31b upstream. mem_cgroup_css_online calls mem_cgroup_put if memcg_init_kmem fails. This is not correct because only memcg_propagate_kmem takes an additional reference while mem_cgroup_sockets_init is allowed to fail as well (although no current implementation fails) but it doesn't take any reference. This all suggests that it should be memcg_propagate_kmem that should clean up after itself so this patch moves mem_cgroup_put over there. Unfortunately this is not that easy (as pointed out by Li Zefan) because memcg_kmem_mark_dead marks the group dead (KMEM_ACCOUNTED_DEAD) if it is marked active (KMEM_ACCOUNTED_ACTIVE) which is the case even if memcg_propagate_kmem fails so the additional reference is dropped in that case in kmem_cgroup_destroy which means that the reference would be dropped two times. The easiest way then would be to simply remove mem_cgrroup_put from mem_cgroup_css_online and rely on kmem_cgroup_destroy doing the right thing.

2013-07-21ARM: 7769/1: Cortex-A15: fix erratum 798181 implementationMarc Zyngier
commit 0d0752bca1f9a91fb646647aa4abbb21156f316c upstream. Looking into the active_asids array is not enough, as we also need to look into the reserved_asids array (they both represent processes that are currently running). Also, not holding the ASID allocator lock is racy, as another CPU could schedule that process and trigger a rollover, making the erratum workaround miss an IPI. Exposing this outside of context.c is a little ugly on the side, so let's define a new entry point that the erratum workaround can call to obtain the cpumask.

2013-07-21ARM: 7768/1: prevent risks of out-of-bound access in ASID allocatorMarc Zyngier
commit b8e4a4740fa2b17c0a447b3ab783b3dc10702e27 upstream. On a CPU that never ran anything, both the active and reserved ASID fields are set to zero. In this case the ASID_TO_IDX() macro will return -1, which is not a very useful value to index a bitmap. Instead of trying to offset the ASID so that ASID #1 is actually bit 0 in the asid_map bitmap, just always ignore bit 0 and start the search from bit 1. This makes the code a bit more readable, and without risk of OoB access.

2013-07-21ARM: 7767/1: let the ASID allocator handle suspended animationMarc Zyngier
commit ae120d9edfe96628f03d87634acda0bfa7110632 upstream. When a CPU is running a process, the ASID for that process is held in a per-CPU variable (the "active ASIDs" array). When the ASID allocator handles a rollover, it copies the active ASIDs into a "reserved ASIDs" array to ensure that a process currently running on another CPU will continue to run unaffected. The active array is zero-ed to indicate that a rollover occurred. Because of this mechanism, a reserved ASID is only remembered for a single rollover. A subsequent rollover will completely refill the reserved ASIDs array. In a severely oversubscribed environment where a CPU can be prevented from running for extended periods of time (think virtual machines), the above has a horrible side effect: [P{a} denotes process P running with ASID a] CPU-0 CPU-1 A{x} [active = <x 0>] [suspended] runs B{y} [active = <x y>] [rollover: active = <0 0> reserved = <x y>] runs B{y} [active = <0 y> reserved = <x y>] [rollover: active = <0 0> reserved = <0 y>] runs C{x} [active = <0 x>] [resumes] runs A{x} At that stage, both A and C have the same ASID, with deadly consequences. The fix is to preserve reserved ASIDs across rollovers if the CPU doesn't have an active ASID when the rollover occurs.

commit c5f927a6f62196226915f12194c9d0df4e2210d7 upstream. With this change, we no longer lose the innermost entry in the user-mode part of the call chain. See also the x86 port, which includes the ip. It's possible to partially work around this problem by post-processing the data to use the PERF_SAMPLE_IP value, but this works only if the CPU wasn't in the kernel when the sample was taken.

commit e7676a704ee0a1ef71a6b23760b5a8f6896cb1a1 upstream. The filesystem should not be marked inconsistent if ext4_free_blocks() is not able to allocate memory. Unfortunately some callers (most notably ext4_truncate) don't have a way to reflect an error back up to the VFS. And even if we did, most userspace applications won't deal with most system calls returning ENOMEM anyway.

commit 8af8eecc1331dbf5e8c662022272cf667e213da5 upstream. The arithmetics adding delalloc blocks to the number of used blocks in ext4_getattr() can easily overflow on 32-bit archs as we first multiply number of blocks by blocksize and then divide back by 512.

2013-07-21Btrfs: only do the tree_mod_log_free_eb if this is our last refJosef Bacik
commit 7fb7d76f96bfcbea25007d190ba828b18e13d29d upstream. There is another bug in the tree mod log stuff in that we're calling tree_mod_log_free_eb every single time a block is cow'ed. The problem with this is that if this block is shared by multiple snapshots we will call this multiple times per block, so if we go to rewind the mod log for this block we'll BUG_ON() in __tree_mod_log_rewind because we try to rewind a free twice. We only want to call tree_mod_log_free_eb if we are actually freeing the block. With this patch I no longer hit the panic in __tree_mod_log_rewind.

commit 139f807a1eba1e484941a98fb93ee32ad859a6a1 upstream. This fixes bugzilla 57491. If we take a snapshot of a fs with a unlink ongoing and then try to send that root we will run into problems. When comparing with a parent root we will search the parents and the send roots commit_root, which if we've just created the snapshot will include the file that needs to be evicted by the orphan cleanup. So when we find a changed extent we will try and copy that info into the send stream, but when we lookup the inode we use the normal root, which no longer has the inode because the orphan cleanup deleted it. The best solution I have for this is to check our otransid with the generation of the commit root and if they match just commit the transaction again, that way we get the changes from the orphan cleanup. With this patch the reproducer I made for this bugzilla no longer returns ESTALE when trying to do the send.

2013-07-21nbd: correct disconnect behaviorPaul Clements
commit c378f70adbc1bbecd9e6db145019f14b2f688c7c upstream. Currently, when a disconnect is requested by the user (via NBD_DISCONNECT ioctl) the return from NBD_DO_IT is undefined (it is usually one of several error codes). This means that nbd-client does not know if a manual disconnect was performed or whether a network error occurred. Because of this, nbd-client's persist mode (which tries to reconnect after error, but not after manual disconnect) does not always work correctly. This change fixes this by causing NBD_DO_IT to always return 0 if a user requests a disconnect. This means that nbd-client can correctly either persist the connection (if an error occurred) or disconnect (if the user requested it).

commit ef962df057aaafd714f5c22ba3de1be459571fdf upstream. Inlined xattr shared free space of inode block with inlined data or data extent record, so the size of the later two should be adjusted when inlined xattr is enabled. See ocfs2_xattr_ibody_init(). But this isn't done well when reflink. For inode with inlined data, its max inlined data size is adjusted in ocfs2_duplicate_inline_data(), no problem. But for inode with data extent record, its record count isn't adjusted. Fix it, or data extent record and inlined xattr may overwrite each other, then cause data corruption or xattr failure.

commit 91bdad0b6237c25a7bf8fd4604d0cc64a2005a23 upstream. The role of acpi_bus_update_power() is to update the given ACPI device object's power.state field to reflect the current physical state of the device (as inferred from the configuration of power resources and _PSC, if available). For this purpose it calls acpi_device_set_power() that should update the power resources' reference counters and set power.state as appropriate. However, that doesn't work if the "new" state is D1, D2 or D3hot and the the current value of power.state means D3cold, because in that case acpi_device_set_power() will refuse to transition the device from D3cold to non-D0. To address this problem, make acpi_bus_update_power() call acpi_power_transition() directly to update the power resources' reference counters and only use acpi_device_set_power() to put the device into D0 if the current physical state of it cannot be determined.

2013-07-21xen/pcifront: Deal with toolstack missing 'XenbusStateClosing' state.Konrad Rzeszutek Wilk
commit 098b1aeaf4d6149953b8f1f8d55c21d85536fbff upstream. There are two tool-stack that can instruct the Xen PCI frontend and backend to change states: 'xm' (Python code with a daemon), and 'xl' (C library - does not keep state changes). With the 'xm', the path to disconnect a single PCI device (xm pci-detach <guest> <BDF>) is: 4(Connected)->7(Reconfiguring*)-> 8(Reconfigured)-> 4(Connected)->5(Closing*). The * is for states that the tool-stack sets. For 'xl', it is similar: 4(Connected)->7(Reconfiguring*)-> 8(Reconfigured)-> 4(Connected) Both of them also tear down the XenBus structure, so the backend state ends up going in the 3(Initialised) and calls pcifront_xenbus_remove. When a PCI device is plugged back in (xm pci-attach <guest> <BDF>) both of them follow the same pattern: 2(InitWait*), 3(Initialized*), 4(Connected*)->4(Connected). [xen-pcifront ignores the 2,3 state changes and only acts when 4 (Connected) has been reached] Note that this is for a _single_ PCI device. If there were two PCI devices and only one was disconnected 'xm' would show the same state changes. The problem is that git commit 3d925320e9e2de162bd138bf97816bda8c3f71be ("xen/pcifront: Use Xen-SWIOTLB when initting if required") introduced a mechanism to initialize the SWIOTLB when the Xen PCI front moves to Connected state. It also had some aggressive seatbelt code check that would warn the user if one tried to change to Connected state without hitting first the Closing state: pcifront pci-0: PCI frontend already installed! However, that code can be relaxed and we can continue on working even if the frontend is instructed to be the 'Connected' state with no devices and then gets tickled to be in 'Connected' state again. In other words, this 4(Connected)->5(Closing)->4(Connected) state was expected, while 4(Connected)->.... anything but 5(Closing)->4(Connected) was not. This patch removes that aggressive check and allows Xen pcifront to work with the 'xl' toolstack (for one or more PCI devices) and with 'xm' toolstack (for more than two PCI devices).

The patch is intended as the completion of [1]. It should fix the double idle times seen in PV guests' /proc/stat [2]. It should be orthogonal to stolen time accounting (the removed code seems to be isolated). The approach may be completely misguided. [1] https://lkml.org/lkml/2011/10/6/10 [2] http://lists.xensource.com/archives/html/xen-devel/2010-08/msg01068.html John took the time to retest this patch on top of v3.10 and reported: "idle time is correctly incremented for pv and hvm for the normal case, nohz=off and nohz=idle." so lets put this patch in.

2013-07-21x86, efi: retry ExitBootServices() on failureZach Bobroff
commit d3768d885c6ccbf8a137276843177d76c49033a7 upstream. ExitBootServices is absolutely supposed to return a failure if any ExitBootServices event handler changes the memory map. Basically the get_map loop should run again if ExitBootServices returns an error the first time. I would say it would be fair that if ExitBootServices gives an error the second time then Linux would be fine in returning control back to BIOS. The second change is the following line: again: size += sizeof(*mem_map) * 2; Originally you were incrementing it by the size of one memory map entry. The issue here is all related to the low_alloc routine you are using. In this routine you are making allocations to get the memory map itself. Doing this allocation or allocations can affect the memory map by more than one record.

2013-07-21parisc: optimize mtsp(0,sr) inline assemblyHelge Deller
commit 92b59929825d67db575043a76651865d16873b36 upstream. If the value which should be moved into a space register is zero, we can optimize the inline assembly to become "mtsp %r0,%srX". Signed-off-by: Helge Deller <deller@gmx.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-07-21parisc: fix LMMIO mismatch between PAT length and MASK registerHelge Deller
commit dac76f1be5beaea4af9afe85fb475c73de0b8731 upstream. The LMMIO length reported by PAT and the length given by the LBA MASK register are not consistent. This leads e.g. to a not-working ATI FireGL card with the radeon DRM driver since the memory can't be mapped. Fix this by correctly adjusting the resource sizes.
