This causes ecryptfs_crypt_stat.num_header_bytes_at_front to be 0, since there is no header data at the front of the file. This results in too much memory being requested and ENOMEM being returned from ecryptfs_write_metadata(). This patch fixes the problem by using the num_header_bytes_at_front variable for specifying the max size of the metadata, despite whether it is stored in the header or xattr.

If the metadata is stored in a xattr, the metadata is moved to the file header when the file is read inside the eCryptfs mount. Because of this, we should strip the ECRYPTFS_METADATA_IN_XATTR flag from the header's flag section. This allows eCryptfs to treat the file as an eCryptfs file with a header at the front.

So the additional chipset flush introduced in commit 2162e6a2b0cd5acbb9bd8a3c94e1c1269b078295 Author: Dave Airlie Date: Wed Nov 21 16:36:31 2007 +1000 agp/intel: Add chipset flushing support for i8xx chipsets. to fix a GTT problem makes absolutely no sense. If this would really be needed for AGP chipsets, too, we should add it to all i8xx agp drivers, not just one.

The intel_output naming is inherited from the UMS code, which had a structure of screen -> CRTC -> output. The DRM code has an additional notion of encoder/connector, so the structure is screen -> CRTC -> encoder -> connector. This is a useful structure for SDVO encoders which can support multiple connectors (each of which requires different programming in the one encoder and could be connected to different CRTCs), or for DVI-I, where multiple encoders feed into the connector for whether it's used for digital or analog. Most of our code is encoder-related, so transition it to talking about encoders before we start trying to distinguish connectors. This patch is produced by sed s/intel_output/intel_encoder/ over the driver.

That code assumes the dentry is unhashed, but a recent server-side change started returning NULL leases on lookup failure, causing the .snap dentry to be hashed and NULL by ceph_fill_trace(). This causes dentry hash chain corruption, or a dies when d_rehash() includes BUG_ON(!d_unhashed(entry)); So, avoid processing the NULL dentry lease if it the dentry matches the snapdir name in ceph_fill_trace().

However, we did run into problems when we went to write back the pages because the 'oldest' snapc is determined by the oldest cap_snap, and that may be the newer snapc that reflects the deletion. This caused confusion and an infinite loop in ceph_update_writeable_page(). Change the snapc checks to allow writeback of any snapc that is equal to OR older than the 'oldest' snapc. When there are no cap_snaps, we were also using the realm's latest snapc for writeback, which complicates ceph_put_wrbufffer_cap_refs(). Instead, use i_head_snapc, the most snapc used for the most recent ('head') data. This makes the writeback snapc (ceph_osd_request.r_snapc) _always_ match a capsnap or i_head_snapc. Also, in writepags_finish(), drop the snapc referenced by the _page_ and do not assume it matches the request snapc (it may not anymore).

It is thus possible that the metadata has been written back to the MDS but the OSD data has not when the cap_snap is created. This results in a cap_snap with dirty(caps) == 0. The problem is that cap writeback to the MDS isn't necessary, and a FLUSHSNAP cap op gets no ack from the MDS. This leaves the cap_snap attached to the inode along with its inode reference. Fix the problem by dropping the cap_snap if it becomes 'complete' (all pages written out) and dirty(caps) == 0 in ceph_put_wrbuffer_cap_refs(). Also, BUG() in __ceph_flush_snaps() if we encounter a cap_snap with dirty(caps) == 0.

This requires order-4 allocation for txq->cmd[]. In situations like s2ram, this usually leads to allocation failure in the memory subsystem. The patch fixed this problem by allocating the Tx queues memory only at the first time. Later iwl_down/iwl_up only initialize but don't free and reallocate them. The memory is freed at the device removal time. BTW, we have already done this for the Rx queue.

However, if the bh has already been written and the bh reclaimed for some other purpose, AND if the inode is the only one in the inode table block in use, then ext4_get_inode_loc() will not read the inode table block from disk, but as an optimization, fill the block with zero's assuming that its caller will copy in the on-disk version of the inode. This is not done by ext4_write_inode(), so the contents of the inode can simply get lost. The fix is to use __ext4_get_inode_loc() with in_mem set to 0, instead of ext4_get_inode_loc(). Long term the API needs to be fixed so it's obvious why latter is not safe.

When initializaing the IOMMU, we attach devices to their domains before the IOMMU is fully (re)initialized. Attaching a device will issue some important invalidations. In the context of the newly kexec'd kdump kernel, the IOMMU may have stale cached data from the original kernel. Because we do the attach too early, the invalidation commands are placed in the new command buffer before the IOMMU is updated w/ that buffer. This leaves the stale entries in the kdump context and can renders device unusable. Simply enable the IOMMU before we do the attach.

It does negotiation in all cases, usually there is no need 2. It incorrectly attempts to negotiate the throughput class in one direction only. There are separate throughput classes for input and output and if either is negotiated both mist be negotiates. This is bug https://bugzilla.kernel.org/show_bug.cgi?id=15681 This bug was first reported by Daniel Ferenci to the linux-x25 mailing list on 6/8/2004, but is still present. The current (2.6.34) x.25 code doesn't seem to know that the X.25 throughput facility includes two values, one for the required throughput outbound, one for inbound. This causes it to attempt to negotiate throughput 0x0A, which is throughput 9600 inbound and the illegal value "0" for inbound throughput. Because of this some X.25 devices (e.g. Cisco 1600) refuse to connect to Linux X.25. The following patch fixes this behaviour. Unless the user specifies a required throughput it does not attempt to negotiate. If the user does not specify a throughput it accepts the suggestion of the remote X.25 system.

Here are details of my experiments with how Windows handles it: https://bugzilla.kernel.org/show_bug.cgi?id=15701 Signed-off-by: Bjorn Helgaas Signed-off-by: Jesse Barnes --- arch/x86/pci/acpi.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/arch/x86/pci/acpi.c b/arch/x86/pci/acpi.c index c7b1ebfb7da7..334153ca4c30 100644 --- a/arch/x86/pci/acpi.c +++ b/arch/x86/pci/acpi.c @@ -71,8 +71,7 @@ resource_to_addr(struct acpi_resource *resource, if (ACPI_SUCCESS(status) && (addr->resource_type == ACPI_MEMORY_RANGE || addr->resource_type == ACPI_IO_RANGE) && - addr->address_length > 0 && - addr->producer_consumer == ACPI_PRODUCER) { + addr->address_length > 0) { return AE_OK; } return AE_ERROR; From 4352aa5bbf1d0080c2dcf904ce1e4be0a1cb5937 Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Thu, 25 Mar 2010 13:03:30 -0700 Subject: [PATCH 074/897] PCI aerdrv: use correct bit defines and add 2ms delay to aer_root_reset While testing completion timeouts I found that hardware was not recovering. It looks like the hot reset was never being propagated to the endpoint devices on the bus due to the fact that we were clearing the bit too quickly. The documentation I have states that we should be transmitting hot reset TS1s for 2ms. To achieve this I have added a 2ms delay from the time we set the secondary bus reset bit to the time we clear it. In addition I changed the define used for the secondary bus reset bit to match the register define that was being used.

Fix this by simply using probe_kernel_address() when we rewind the frame pointer. This issue will have a much more proper fix in the next version of the perf_arch_fetch_caller_regs() API that will only need to rewind to the first caller.

This is because such a setting was a lie since it implies that the checksum field of the packet is properly filled in. Instead what happens normally is that CHECKSUM_PARTIAL is set and skb->csum is calculated as needed. But this was only happening for TCP data packets (via the skb->ip_summed assignment done in tcp_sendmsg()). It doesn't happen for non-data packets like ACKs etc. Fix this by setting skb->ip_summed in the common non-data packet constructor. It already is setting skb->csum to zero. But this reminds us that we still have things like ip_output.c's ip_dev_loopback_xmit() which sets skb->ip_summed to the value CHECKSUM_UNNECESSARY, which Herbert's patch teaches us is not valid. So we'll have to address that at some point too. Signed-off-by: David S.

According to Arnaud, the lock succeeds the first time he opens the file (since we cannot do a delegated open) but then fails after we start using delegated opens. The following patch fixes it by ensuring that locking behaviour is governed by a per-filesystem capability flag that is initially set, but gets cleared if the server ever returns an OPEN without the NFS4_OPEN_RESULT_LOCKTYPE_POSIX flag being set.

This cache flush is explicit through flush_cache_kmaps() in flush_all_zero_pkmaps(), or through __cpuc_flush_dcache_area() in kunmap_atomic(). There is also an implicit flush of those highmem pages that were part of a process that just terminated making those pages free as the whole VIVT cache has to be flushed on every task switch. Hence unmapped highmem pages need no cache maintenance in that case. However unmapped pages may still be cached with a VIPT cache because the cache is tagged with physical addresses. There is no need for a whole cache flush during task switching for that reason, and despite the explicit cache flushes in flush_all_zero_pkmaps() and kunmap_atomic(), some highmem pages that were mapped in user space end up still cached even when they become unmapped. So, we do have to perform cache maintenance on those unmapped highmem pages in the context of DMA when using a VIPT cache. Unfortunately, it is not possible to perform that cache maintenance using physical addresses as all the L1 cache maintenance coprocessor functions accept virtual addresses only. Therefore we have no choice but to set up a temporary virtual mapping for that purpose. And of course the explicit cache flushing when unmapping a highmem page on a system with a VIPT cache now can go, which should increase performance. While at it, because the code in __flush_dcache_page() has to be modified anyway, let's also make sure the mapped highmem pages are pinned with kmap_high_get() for the duration of the cache maintenance operation. Because kunmap() does unmap highmem pages lazily, it was reported by Gary King that those pages ended up being unmapped during cache maintenance on SMP causing segmentation faults.

These are needed due to some performance concerns with using rcu_dereference() where it is not required, aside from the need for lockdep/sparse checking. The new rcu_access_pointer() primitive is for the case where the pointer is be fetch and not dereferenced. This primitive may be used without protection, RCU or otherwise, due to the fact that it uses ACCESS_ONCE(). The new rcu_dereference_protected() primitive is for the case where updates are prevented, for example, due to holding the update-side lock. This primitive does neither ACCESS_ONCE() nor smp_read_barrier_depends(), so can only be used when updates are somehow prevented. Suggested-by: David Howells Signed-off-by: Paul E.

Tsirkin" Date: Tue, 13 Apr 2010 04:59:44 +0000 Subject: [PATCH 164/897] tun: orphan an skb on tx The following situation was observed in the field: tap1 sends packets, tap2 does not consume them, as a result tap1 can not be closed. This happens because tun/tap devices can hang on to skbs undefinitely. As noted by Herbert, possible solutions include a timeout followed by a copy/change of ownership of the skb, or always copying/changing ownership if we're going into a hostile device. This patch implements the second approach. Note: one issue still remaining is that since skbs keep reference to tun socket and tun socket has a reference to tun device, we won't flush backlog, instead simply waiting for all skbs to get transmitted. At least this is not user-triggerable, and this was not reported in practice, my assumption is other devices besides tap complete an skb within finite time after it has been queued. A possible solution for the second issue would not to have socket reference the device, instead, implement dev->destructor for tun, and wait for all skbs to complete there, but this needs some thought, probably too risky for 2.6.34.

It's only used by cmpxchg8b_emu (see db677ffa5f5a for the gory details), and fixing that to be paravirt aware would be more work than simply ignoring it (and AFAICT only help lguest). This makes lguest work on machines which have cmpxchg8b, for kernels compiled for older processors. (We can't emulate it properly: the popf which expects to restore interrupts does not trap).

I didn't revert the register mapping, so we still use the same calling convention as kvm. KVM in more recent incarnations stopped injecting a fault when a guest tried to use the VMCALL instruction from ring 1, so lguest under kvm fails to make hypercalls. It was nice to share code with our KVM cousins, but this was overreach.

There is existing kernel code that uses a larger precision. An example from the audit code: vsnprintf(...,..., " msg='%.1024s'", (char *)data); which overflows precision and truncates to nothing. Extending precision size fixes the audit system issue. Other changes: Change the size of the struct printf_spec.type from u16 to u8 so sizeof(struct printf_spec) stays as small as possible. Reorder the struct members so sizeof(struct printf_spec) remains 64 bits without alignment holes. Document the struct members a bit more.

Since the commit 7b3a177b0d4f92b3431b8dca777313a07533a710, "ALSA: pcm_lib: fix "something must be really wrong" condition", makes the position check more strictly, the DMA position problem is revealed more clearly now. The fix is to use only LPIB for obtaining the position, i.e. passing position_fix=1. This patch adds a static quirk to achieve it as default.

Unfortunately the sync code was unknowingly relying on this call to make sure metadata buffers were flushed via a xfs_buftarg_flush() call to move the tail of the log forward in memory before the final transactions of the sync process were issued. As a result, the old code would write a very recent log tail value to the log by the end of the sync process, and so a subsequent crash would leave nothing for log recovery to do. Hence in qa test 182, log recovery only replayed a small handle for inode fsync transactions in this case. However, with the removal of the extra ->sync_fs call, the log tail was now not moved forward with the inode fsync transactions near the end of the sync procese the first (and only) buftarg flush occurred after these transactions went to disk. The result is that log recovery now sees a large number of transactions for metadata that is already on disk. This usually isn't a problem, but when the transactions include inode chunk allocation, the inode create transactions and all subsequent changes are replayed as we cannt rely on what is on disk is valid. As a result, if the inode was written and contains unlogged changes, the unlogged changes are lost, thereby violating sync semantics. The fix is to always issue a transaction after the buftarg flush occurs is the log iѕ not idle or covered. This results in a dummy transaction being written that contains the up-to-date log tail value, which will be very recent. Indeed, it will be at least as recent as the old code would have left on disk, so log recovery will behave exactly as it used to in this situation.

This is supported by an otherwise totally misleading XXX comment. This bug mostly resulted in tiling-corrupted pixmaps because the kernel allowed too wide buffers to be tiled. Bug brought to the light by the xf86-video-intel 2.11 release because that unconditionally enabled tiling for pixmaps, relying on the kernel to check things. Tiling for the framebuffer was not affected because the ddx does some additional checks there ensure the buffer is within hw-limits. v2: Instead of computing the value that would be written into the hw fence registers and then checking the limits simply check whether the stride is above the 8kb limit. To better document the hw, add some WARN_ONs in i915_write_fence_reg like I've done for the i830 case (using the right limits).

Such disabling happens in NMIs and in other situations where lockdep might expect to recurse on itself. This patch therefore checks current->lockdep_recursion, disabling RCU lockdep splats when this variable is non-zero. In addition, this patch removes the "likely()", as suggested by Lai Jiangshan.

If the caller doesn't instantiate it, it's freed immediately at dput(). ->readdir reads directly from the dcache and depends on the dentries being hashed. When an ecryptfs mount is mounted, it associates the lower file and dentry with the ecryptfs files as they're accessed. When it's umounted and destroys all the in-memory ecryptfs inodes, it fput's the lower_files and d_drop's the lower_dentries. Commit 4981e081 added this and a d_delete in 2008 and several months later commit caeeeecf removed the d_delete. I believe the d_drop() needs to be removed as well. The d_drop effectively hides any file that has been accessed via ecryptfs from the underlying tmpfs since it depends on it being hashed for it to be accessible. I've removed the d_drop on my development node and see no ill effects with basic testing on both tmpfs and persistent storage. As a side effect, after ecryptfs d_drops the dentries on tmpfs, tmpfs BUGs on umount. This is due to the dentries being unhashed. tmpfs->kill_sb is kill_litter_super which calls d_genocide to drop the reference pinning the dentry. It skips unhashed and negative dentries, but shrink_dcache_for_umount_subtree doesn't. Since those dentries still have an elevated d_count, we get a BUG(). This patch removes the d_drop call and fixes both issues.

This caused more dependence on current state to ensure driver will be notified when configuration changes occur. One such problem arises if off-channel is in progress when HT information changes. Since HT is only enabled on the "oper_channel" the driver will never be notified of this change. Usually the driver is notified soon after of a BSS information change (BSS_CHANGED_HT) ... but since the driver did not get a notification that this is a HT channel the new BSS information does not make sense. Fix this by also changing the off-channel information when HT is enabled and thus cause driver to be notified correctly. This fixes a problem in 4965 when associated with 5GHz 40MHz channel. Without this patch the system can associate but is unable to transfer any data, not even ping.

Adding exclusively owned anonymous pages to the top anon_vma reduces rmap scanning overhead, especially in workloads with forking servers. This patch adds a parameter to __page_set_anon_rmap that can be used to indicate whether or not the added page is exclusively owned by the current process. Pages added through page_add_new_anon_rmap are exclusively owned by the current process, and can be added to the top anon_vma. Pages added through page_add_anon_rmap can be either shared or exclusively owned, so we do the conservative thing and add it to the oldest anon_vma. A next step would be to add the exclusive parameter to page_add_anon_rmap, to be used from functions where we do know for sure whether a page is exclusively owned.

The clickpad flags are in cap[0]:4 and cap[1]:0 bits. When the device is detected, the driver now reports only the left button as the supported buttons so that X11 driver can detect that the device is Clickpad. A Clickpad device gives the button events only as the middle button. The kernel driver morphs to the left button. The real handling of Clickpad is done rather in X driver side.

Due to some merge issues with the uname refactoring patches we ended up calling the old uname version for both the old and new system call slots, which lead to the domainname filed never be set which caused failures with libnss_nis.

My recent patch to remove the open-coded checksum sequence in tcp_v6_send_response broke it as we did not set the transport header pointer on the new packet. Actually, there is code there trying to set the transport header properly, but it sets it for the wrong skb ('skb' instead of 'buff').

The problem is that this can cause a race with both copy_creds() and exit_creds() as the two counters, whilst they are of atomic_t type, are only atomic with respect to themselves, and not atomic with respect to each other. This means that if creds_are_invalid() can read the values on one CPU whilst they're being modified on another CPU, and so can observe an evolving state in which the subscribers count now is greater than the usage count a moment before. Switching the order in which the counts are read cannot help, so the thing to do is to remove that particular check. I had considered rechecking the values to see if they're in flux if the test fails, but I can't guarantee they won't appear the same, even if they've changed several times in the meantime. Note that this can only happen if CONFIG_DEBUG_CREDENTIALS is enabled. The problem is only likely to occur with multithreaded programs, and can be tested by the tst-eintr1 program from glibc's "make check". The symptoms look like: CRED: Invalid credentials CRED: At include/linux/cred.h:240 CRED: Specified credentials: ffff88003dda5878 [real][eff] CRED: ->magic=43736564, put_addr=(null) CRED: ->usage=766, subscr=766 CRED: ->*uid = { 0,0,0,0 } CRED: ->*gid = { 0,0,0,0 } CRED: ->security is ffff88003d72f538 CRED: ->security {359, 359} ------------[ cut here ]------------ kernel BUG at kernel/cred.c:850! ...

After receiving a ICMPv6 Too Big message reporting PMTU is less than the IPv6 Minimum Link MTU, sctp *can't* send any data/control chunk that total length including IPv6 head and IPv6 extend head is less than IPV6_MIN_MTU(1280 bytes). The failure occured in p6_fragment(), about reason see following(take SHUTDOWN chunk for example): sctp_packet_transmit (SHUTDOWN chunk, len=16 byte) |------sctp_v6_xmit (local_df=0) |------ip6_xmit |------ip6_output (dst_allfrag is ture) |------ip6_fragment In ip6_fragment(), for local_df=0, drops the the packet and returns EMSGSIZE. The patch fixes it with adding check length of skb->len. In this case, Ipv6 not to fragment upper protocol data, just only add a fragment header before it.

If a sender binds to a particular NIC (SO_BINDTODEVICE), the outgoing traffic is being sent via the first found. The bonded device is thus not taken into an account during the routing. From the ip6_route_output function: If the binding address is multicast, linklocal or loopback, the RT6_LOOKUP_F_IFACE bit is set, but not for global address. So binding global address will neglect SO_BINDTODEVICE-binded device, because the fib6_rule_lookup function path won't check for the flowi::oif field and take first route that fits.

This parameter contains the internal NTP adjusted clock multiplier. The s390x vdso did not use this adjusted multiplier. Instead, it used the constant clock multiplier for gettimeofday() and clock_gettime() variants. This may result in observable time warps as explained in commit 0696b711e. Make the NTP adjusted clock multiplier available to the s390x vdso implementation and use it for time calculations.

This seems to be because all NFSv4 mounts are now cloned, and the cloning logic doesn't copy the rsize and wsize settings from the parent nfs_server. I tested Fedora's 2.6.32.11-99 and it seems to have this problem as well, so I'm guessing that .33, .32, and perhaps older kernels have this issue as well.

It won't be enabled unless an interface driver specifically needs it. Also, it won't be enabled during the FREEZE or QUIESCE phases of hibernation, when the system doesn't respond to wakeup events anyway. Finally, if the device is already runtime-suspended with remote wakeup enabled, but wakeup is supposed to be disabled for the system sleep, the device gets woken up so that it can be suspended again with the proper wakeup setting. This will fix problems people have reported with certain USB webcams that generate wakeup requests when they shouldn't, and as a result cause system suspends to fail.

When a driver claims an interface, it doesn't expect to need to call usb_autopm_get_interface() or usb_autopm_put_interface() for runtime PM to work. Runtime PM can be controlled by the driver's primary interface; the additional interfaces it claims shouldn't interfere. As things stand, the claimed interfaces will prevent the device from autosuspending. To fix this problem, the patch sets interfaces to the suspended state when they are claimed. Also, although in theory this shouldn't matter, the patch changes the suspend code so that interfaces are suspended in reverse order from detection and resuming. This is how the PM core works, and we ought to use the same approach.

One solution would be to lock the orphan dir during the entire transaction, but that's too heavy for a rare error path. Instead, we add a flag, OCFS2_INODE_SKIP_ORPHAN_DIR which tells the inode wipe code that it won't find this inode in the orphan dir.

Due to this erratum, if a code fetch uses this PDE before the TLB entry for the large page is invalidated then it may fetch from a different physical address than specified by either the old large page translation or the new 4-KByte page translation. This erratum may also cause speculative code fetches from incorrect addresses." [http://download.intel.com/design/processor/specupdt/319536.pdf] Where as commit 211b3d03c7400f48a781977a50104c9d12f4e229 seems to workaround errata AAH41 (mixed 4K TLBs) it reduces the window of opportunity for the bug to occur and does not totally remove it. This patch disables mixed 4K/4MB page tables totally avoiding the page splitting and not tripping this processor issue. This is based on an original patch by Colin King.

The intent was that the entry would be hidden from the user via a poisoned d_compare, but this was faulty. This introduced a security issue where unprivileged users could access and modify extended attributes or ACLs belonging to other users, including root. This patch resolves the issue by properly hiding .reiserfs_priv. This was the intent of the xattr poisoning code, but it appears to have never worked as expected. This is fixed by using d_revalidate instead of d_compare. This patch makes -oexpose_privroot a no-op. I'm fine leaving it this way. The effort involved in working out the corner cases wrt permissions and caching outweigh the benefit of the feature.

The issue is that the reiserfs_setattr to shrink the xattr file was moved from before the write to after the write. The root issue has always been in the reiserfs xattr code, but was papered over by the fact that in the shrink case, the file would just be expanded again while the xattr was written. The end result is that the last 8 bytes of xattr data are lost. This patch fixes it to use new_size.

The framebuffer of the NVIDIA graphic cards are located at the following addresses in memory: 9400M: 0xC0010000 9600M GT: 0xB0030000 The patch delivered right here only provides the memory location of the framebuffer of the 9400M device. The 9600M GT is not covered. It is assumed that the 9400M is used when powered up the MBP. The information which device is currently powered and in use is stored in the 64 bytes large EFI variable "gpu-power-prefs". More specifically, byte 0x3B indicates whether 9600M GT (0x00) or 9400M (0x01) is online. The PCI bus IDs are the following: 9400M: PCI 03:00:00 9600M GT: PCI 02:00:00 The EFI variables can be easily read-out and manipulated with "rEFIt", an MBP specific bootloader tool. For more information on how handle rEFIt and EFI variables please consult "http://refit.sourceforge.net" and "http://ubuntuforums.org/archive/index.php/t-1076879.html". IMPORTANT NOTE: The information on how to activate the 9400M device given at "ubuntuforums.org" is not correct, since it states gpu-power-prefs[0x3B] = 0x00 -> 9400M (PCI 02:00:00) gpu-power-prefs[0x3B] = 0x01 -> 9600M GT (PCI 03:00:00) Actually, the assignment of the values and the PCI bus IDs are swapped. Suggestions: ------------ To cover framebuffers of both 9400M and 9600M GT, I would suggest to implement a conditional on "gpu-power-prefs". Depending on the value of byte 0x3B, the according framebuffer is selected. However, this requires kernel access to the EFI variables.

This makes O_SYNC writes to block devices acquire i_mutex for syncing. If we really care about this, we can make block_fsync() drop the i_mutex and reacquire it before it returns. Thanks Jan for such a good commit message! As well as dropping i_mutex, Christoph suggests we should remove the call to sync_blockdev(): > sync_blockdev is an overcomplicated alias for filemap_write_and_wait on > the block device inode, which is exactly what we did just before calling > into ->fsync The patch below incorporates both suggestions.

Ballooning is a technique that allows hypervisor dynamically limit the amount of memory available to the guest (with guest cooperation). In the overcommit scenario, when hypervisor set detects that it needs to shuffle some memory, it instructs the driver to allocate certain number of pages, and the underlying memory gets returned to the hypervisor. Later hypervisor may return memory to the guest by reattaching memory to the pageframes and instructing the driver to "deflate" balloon. We are submitting a standalone driver because KVM maintainer (Avi Kivity) expressed opinion (rightly) that our transport does not fit well into virtqueue paradigm and thus it does not make much sense to integrate with virtio. There were also some concerns whether current ballooning technique is the right thing. If there appears a better framework to achieve this we are prepared to evaluate and switch to using it, but in the meantime we'd like to get this driver upstream. We want to get the driver accepted in distributions so that users do not have to deal with an out-of-tree module and many distributions have "upstream first" requirement. The driver has been shipping for a number of years and users running on VMware platform will have it installed as part of VMware Tools even if it will not come from a distribution, thus there should not be additional risk in pulling the driver into mainline. The driver will only activate if host is VMware so everyone else should not be affected at all.

This results in the routine looping eventually oopsing on an out of bounds memory access. Note this bug is usually hidden, only triggering on trailing junk after one or more correct compressed blocks. The case of the compressed archive being complete junk is (by accident?) caught by the if (state != Reset) check because state is initialised to Start, but not updated due to the decompressor not having been called.

The two inodes look like: before: ino 0x101 (target), num_extents 11, Max in-fork extents 6, broot size 40, fork offset 96 before: ino 0x115 (temp), num_extents 5, Max in-fork extents 3, broot size 40, fork offset 56 after: ino 0x101 (target), num_extents 5, Max in-fork extents 6, broot size 40, fork offset 96 after: ino 0x115 (temp), num_extents 11, Max in-fork extents 3, broot size 40, fork offset 56 Basically the target inode ends up with 5 extents in btree format, but it had space for 6 extents in extent format, so ends up incorrect. Notably here the broot size is the same, and that is where the kernel code is going wrong - the btree root will fit, so it lets the swap go ahead. The check should not allow the swap to take place if the number of extents while in btree format is less than the number of extents that can fit in the inode in extent format. Adding that check will prevent this swap and corruption from occurring.

Later in acpi_bus_receive_event() we copy the whole struct to another buffer with memcpy(). If the new buffer is stored on the stack, kmemcheck prints a warning about the unitialized space after the NULL terminators. It's true that the space is uninitialized, but it's harmless. The buffer is only used in acpi_system_read_event() and we don't read past the NULL terminators.

For standard frames, 82573/82574/82583 can enable L1 but L0s must be disabled, and for jumbo frames 82573/82574 must disable L1. This allows for some parts to enable L1 in certain configurations leading to better power savings. Also according to the same errata, Early Receive (ERT) should be disabled on 82573 when using jumbo frames.

It has been reported that under certain heavy traffic conditions in MSI-X mode, the driver can lose an MSI-X vector causing all packets in the associated rx/tx ring pair to be dropped. The problem is caused by the chip dropping the write to unmask the MSI-X vector by the kernel (when migrating the IRQ for example). This can be prevented by increasing the GRC timeout value for these register read and write operations. Thanks to Dell for helping us debug this problem.

The bonding driver calls ndo_vlan_rx_register() while holding bond->lock. The bnx2 driver calls bnx2_netif_stop() to stop the rx handling while changing the vlgrp. The call also stops the cnic driver which sleeps while the bond->lock is held and cause the warning. This code path only needs to stop the NAPI rx handling while we are changing the vlgrp. Since no reset is going to occur, there is no need to stop cnic in this case. By adding a parameter to bnx2_netif_stop() to skip stopping cnic, we can avoid the warning.

This can be tested by: ring=`keyctl newring fred @s` keyctl request2 user debug:a a keyctl request user debug:a $ring keyctl list $ring If it says: keyring is empty then it didn't work. If it shows something like: 1 key in keyring: 1070462727: --alswrv 0 0 user: debug:a then it did. request_key() system call is meant to recursively search all your keyrings for the key you desire, and, optionally, if it doesn't exist, call out to userspace to create one for you. If request_key() finds or creates a key, it should, optionally, create a link to that key from the destination keyring specified. Therefore, if, after a successful call to request_key() with a desination keyring specified, you see the destination keyring empty, the code didn't work correctly. If you see the found key in the keyring, then it did - which is what the patch is required for.

Summary of the changes: 1. Improved error handling. 2. Added the missing timeout arguments to usb_control_msg(). The following is a new Linux driver which exposes certain models of Sierra Wireless modems to the operating system as Network Interface Cards (NICs). This driver requires a version of the sierra.c driver which supports blacklisting to work properly. The blacklist in sierra.c rejects the interfaces claimed by sierra_net.c. Likewise, the sierra_net.c driver only accepts (i.e. whitelists) the interface(s) used for USB-to-WWAN traffic. The version of sierra.c which supports blacklisting is available from the sierra wireless knowledge base page for older kernels. It is also available in Linux kernel starting from version 2.6.31. This driver works with all Sierra Wireless devices configured with PID=68A3 like USB305, USB306 provided the corresponding firmware version is I2.0 (for USB305) or M3.0 (for USB306) and later. This driver will not work with earlier firmware versions than the ones shown above. In this case the driver will issue an error message indicating incompatibility and will not serve the device's USB-to-WWAN interface. Sierra_net.c sits atop a pre-existing Linux driver called usbnet.c. A series of hook functions are provided in sierra_net.c which are called by usbnet.c in response to a particular condition such as receipt or transmission of a data packet. As such, usbnet.c does most of the work of making a modem appear to the system as a network device and for properly exchanging traffic between the USB subsystem and the Network card interface. Sierra_net.c is concerned with managing the data exchanged between the USB-to-WWAN interface and the upper layers of the operating system.

Unfortunately the old method now caps the topology to work around issues with legacy operating systems. For Linux to get the correct topology we need to use the new form 1 affinity information. We set the form 1 field in the client architecture, and if we see "1" in the ibm,associativity-form property firmware supports form 1 affinity and we should look at the first field in the ibm,associativity-reference-points array. If not we use the second field as we always have.

Linux has been computing Address Spaces as [_MIN to _MIN + _LEN - 1]. Based on the tests in the bug reports below, Windows apparently uses [_MIN to _MAX]. Per spec (ACPI 4.0, Table 6-40), for _CRS fixed-size, fixed location descriptors, "_LEN must be (_MAX - _MIN + 1)", and when that's true, it doesn't matter which way we compute the end. But of course, there are BIOSes that don't follow this rule, and we're better off if Linux handles those exceptions the same way as Windows. This patch makes Linux use [_MIN to _MAX], as Windows seems to do. This effectively reverts d558b483d5 and 03db42adfe and replaces them with simpler code. https://bugzilla.kernel.org/show_bug.cgi?id=14337 (round) https://bugzilla.kernel.org/show_bug.cgi?id=15480 (truncate) Signed-off-by: Bjorn Helgaas Signed-off-by: Jesse Barnes --- arch/x86/pci/acpi.c | 40 ++-------------------------------------- 1 file changed, 2 insertions(+), 38 deletions(-) diff --git a/arch/x86/pci/acpi.c b/arch/x86/pci/acpi.c index 44f83ce02470..31930fd30ea9 100644 --- a/arch/x86/pci/acpi.c +++ b/arch/x86/pci/acpi.c @@ -121,30 +121,6 @@ count_resource(struct acpi_resource *acpi_res, void *data) return AE_OK; } -static void -align_resource(struct acpi_device *bridge, struct resource *res) -{ - int align = (res->flags & IORESOURCE_MEM) ? 16 : 4; - - /* - * Host bridge windows are not BARs, but the decoders on the PCI side - * that claim this address space have starting alignment and length - * constraints, so fix any obvious BIOS goofs. - */ - if (!IS_ALIGNED(res->start, align)) { - dev_printk(KERN_DEBUG, &bridge->dev, - "host bridge window %pR invalid; " - "aligning start to %d-byte boundary\n", res, align); - res->start &= ~(align - 1); - } - if (!IS_ALIGNED(res->end + 1, align)) { - dev_printk(KERN_DEBUG, &bridge->dev, - "host bridge window %pR invalid; " - "aligning end to %d-byte boundary\n", res, align); - res->end = ALIGN(res->end, align) - 1; - } -} - static acpi_status setup_resource(struct acpi_resource *acpi_res, void *data) { @@ -154,7 +130,7 @@ setup_resource(struct acpi_resource *acpi_res, void *data) acpi_status status; unsigned long flags; struct resource *root, *conflict; - u64 start, end, max_len; + u64 start, end; status = resource_to_addr(acpi_res, &addr); if (!ACPI_SUCCESS(status)) @@ -171,19 +147,8 @@ setup_resource(struct acpi_resource *acpi_res, void *data) } else return AE_OK; - max_len = addr.maximum - addr.minimum + 1; - if (addr.address_length > max_len) { - dev_printk(KERN_DEBUG, &info->bridge->dev, - "host bridge window length %#llx doesn't fit in " - "%#llx-%#llx, trimming\n", - (unsigned long long) addr.address_length, - (unsigned long long) addr.minimum, - (unsigned long long) addr.maximum); - addr.address_length = max_len; - } - start = addr.minimum + addr.translation_offset; - end = start + addr.address_length - 1; + end = addr.maximum + addr.translation_offset; res = &info->res[info->res_num]; res->name = info->name; @@ -191,7 +156,6 @@ setup_resource(struct acpi_resource *acpi_res, void *data) res->start = start; res->end = end; res->child = NULL; - align_resource(info->bridge, res); if (!pci_use_crs) { dev_printk(KERN_DEBUG, &info->bridge->dev, From acf82b85a70f39786e3cbb1ffed8655bcc972424 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Thu, 22 Apr 2010 11:28:39 +0200 Subject: [PATCH 518/897] nfs: fix some issues in nfs41_proc_reclaim_complete() The original code passed an ERR_PTR() to rpc_put_task() and instead of returning zero on success it returned -ENOMEM.

The problem is in sctp_process_unk_param: if (NULL == *errp) *errp = sctp_make_op_error_space(asoc, chunk, ntohs(chunk->chunk_hdr->length)); if (*errp) { sctp_init_cause(*errp, SCTP_ERROR_UNKNOWN_PARAM, WORD_ROUND(ntohs(param.p->length))); sctp_addto_chunk(*errp, WORD_ROUND(ntohs(param.p->length)), param.v); When we allocate an error chunk, we assume that the worst case scenario requires that we have chunk_hdr->length data allocated, which would be correct nominally, given that we call sctp_addto_chunk for the violating parameter. Unfortunately, we also, in sctp_init_cause insert a sctp_errhdr_t structure into the error chunk, so the worst case situation in which all parameters are in violation requires chunk_hdr->length+(sizeof(sctp_errhdr_t)*param_count) bytes of data. The result of this error is that a deliberately malformed packet sent to a listening host can cause a remote DOS, described in CVE-2010-1173: http://cve.mitre.org/cgi-bin/cvename.cgi?name=2010-1173 I've tested the below fix and confirmed that it fixes the issue. We move to a strategy whereby we allocate a fixed size error chunk and ignore errors we don't have space to report.

Linux has been computing Address Spaces as [_MIN to _MIN + _LEN - 1]. Based on the tests in the bug reports below, Windows apparently uses [_MIN to _MAX]. Per spec (ACPI 4.0, Table 6-40), for _CRS fixed-size, fixed location descriptors, "_LEN must be (_MAX - _MIN + 1)", and when that's true, it doesn't matter which way we compute the end. But of course, there are BIOSes that don't follow this rule, and we're better off if Linux handles those exceptions the same way as Windows. This patch makes Linux use [_MIN to _MAX], as Windows seems to do. This effectively reverts 3162b6f0c5e and replaces it with simpler code. https://bugzilla.kernel.org/show_bug.cgi?id=14337 (round) https://bugzilla.kernel.org/show_bug.cgi?id=15480 (truncate) Signed-off-by: Bjorn Helgaas Signed-off-by: Len Brown --- drivers/pnp/pnpacpi/rsparser.c | 26 ++++---------------------- 1 file changed, 4 insertions(+), 22 deletions(-) diff --git a/drivers/pnp/pnpacpi/rsparser.c b/drivers/pnp/pnpacpi/rsparser.c index 35bb44af49b3..100e4d9372f1 100644 --- a/drivers/pnp/pnpacpi/rsparser.c +++ b/drivers/pnp/pnpacpi/rsparser.c @@ -274,26 +274,6 @@ static void pnpacpi_parse_allocated_busresource(struct pnp_dev *dev, pnp_add_bus_resource(dev, start, end); } -static u64 addr_space_length(struct pnp_dev *dev, u64 min, u64 max, u64 len) -{ - u64 max_len; - - max_len = max - min + 1; - if (len <= max_len) - return len; - - /* - * Per 6.4.3.5, _LEN cannot exceed _MAX - _MIN + 1, but some BIOSes - * don't do this correctly, e.g., - * https://bugzilla.kernel.org/show_bug.cgi?id=15480 - */ - dev_info(&dev->dev, - "resource length %#llx doesn't fit in %#llx-%#llx, trimming\n", - (unsigned long long) len, (unsigned long long) min, - (unsigned long long) max); - return max_len; -} - static void pnpacpi_parse_allocated_address_space(struct pnp_dev *dev, struct acpi_resource *res) { @@ -309,7 +289,8 @@ static void pnpacpi_parse_allocated_address_space(struct pnp_dev *dev, return; } - len = addr_space_length(dev, p->minimum, p->maximum, p->address_length); + /* Windows apparently computes length rather than using _LEN */ + len = p->maximum - p->minimum + 1; window = (p->producer_consumer == ACPI_PRODUCER) ? 1 : 0; if (p->resource_type == ACPI_MEMORY_RANGE) @@ -330,7 +311,8 @@ static void pnpacpi_parse_allocated_ext_address_space(struct pnp_dev *dev, int window; u64 len; - len = addr_space_length(dev, p->minimum, p->maximum, p->address_length); + /* Windows apparently computes length rather than using _LEN */ + len = p->maximum - p->minimum + 1; window = (p->producer_consumer == ACPI_PRODUCER) ? 1 : 0; if (p->resource_type == ACPI_MEMORY_RANGE) From d9e80b7de91db05c1c4d2e5ebbfd70b3b3ba0e0f Mon Sep 17 00:00:00 2001 From: Al Viro Date: Thu, 29 Apr 2010 03:10:43 +0100 Subject: [PATCH 533/897] nfs d_revalidate() is too trigger-happy with d_drop() If dentry found stale happens to be a root of disconnected tree, we can't d_drop() it; its d_hash is actually part of s_anon and d_drop() would simply hide it from shrink_dcache_for_umount(), leading to all sorts of fun, including busy inodes on umount and oopsen after that.

Fix tusb6010 accordingly. To compile, also dummy musb_platform_save and restore functions need to be added. Also change the order of musb_read_fifo() to happen after dma_cache_maint to have the DMA operations completed before moving the remaining unaligned bytes with PIO. The DMA access and PIO touch different areas of the FIFO, so this change only makes the code a bit easier to follow. Tested on n810 and g_ether with variable size ping test. The test seems to fail for some ping sizes, but that seems to be a different problem.

For periodic endpoints, we must let the xHCI hardware know the maximum payload an endpoint can transfer in one service interval. The xHCI specification refers to this as the Maximum Endpoint Service Interval Time Payload (Max ESIT Payload). This is used by the hardware for bandwidth management and scheduling of packets. For SuperSpeed endpoints, the maximum is calculated by multiplying the max packet size by the number of bursts and the number of opportunities to transfer within a service interval (the Mult field of the SuperSpeed Endpoint companion descriptor). Devices advertise this in the wBytesPerInterval field of their SuperSpeed Endpoint Companion Descriptor. For high speed devices, this is taken by multiplying the max packet size by the "number of additional transaction opportunities per microframe" (the high bits of the wMaxPacketSize field in the endpoint descriptor). For FS/LS devices, this is just the max packet size. The other thing we must set in the endpoint context is the Average TRB Length. This is supposed to be the average of the total bytes in the transfer descriptor (TD), divided by the number of transfer request blocks (TRBs) it takes to describe the TD. This gives the host controller an indication of whether the driver will be enqueuing a scatter gather list with many entries comprised of small buffers, or one contiguous buffer. It also takes into account the number of extra TRBs you need for every TD. This includes No-op TRBs and Link TRBs used to link ring segments together. Some drivers may choose to chain an Event Data TRB on the end of every TD, thus increasing the average number of TRBs per TD. The Linux xHCI driver does not use Event Data TRBs. In theory, if there was an API to allow drivers to state what their bandwidth requirements are, we could set this field accurately. For now, we set it to the same number as the Max ESIT payload.

Latest SL811HS datasheet (Document 38-08008 Rev. *D) indicates that bit 6 (SL11H_INTMASK_RD) of the Interrupt Status Register together with bit 5 (SL11H_INTMASK_INSRMV) can be used to determine whether a device has been inserted or removed.

The function dt3155_init_isr actually reads the I2C CONFIG register into the global I2C_CSR union variable then modifies the bit. It then does a write to the I2C CONFIG register with the global I2C_CONFIG union variable which is not even set with a value anywhere in the driver. My guess is 50Hz operation doesn't even work as-is. Fix this by actually reading and writing the correct register with the correct value.

In the 64-bit kernel we use swapper_pg_dir for three different things. 1) xuseg mappings for kernel threads. 2) vmap mappings for all kernel-space accesses in xkseg. 3) vmap mappings for kernel modules in ksseg (kseg2). Due to how the TLB refill handlers work, any mapping established in xkseg or ksseg will also establish a xuseg mapping that should never be used by the kernel. In order to be able to use exceptions to trap NULL pointer dereferences, we need to ensure that nothing is mapped at address zero. Since vmap mappings in xkseg are reflected in xuseg, this means we need to ensure that there are no vmap mappings established at the start of xkseg. So we move back VMALLOC_START to avoid establishing vmap mappings at the start of xkseg.

For some combinations of PAGE_SIZE and vmbits, it is possible to have userspace access that are beyond what is covered by the PGD, but within vmbits. Such an access would cause the TLB refill handler to load garbage values for PMD and PTE potentially giving userspace access to parts of the physical address space to which it is not entitled. In the TLB refill hot path, we add a single dsrl instruction so we can check if any bits outside of the range covered by the PGD are set. In the vmalloc side we then separate the bad case from the normal vmalloc case and call tlb_do_page_fault_0 if warranted. This slows us down a bit, but has the benefit of yielding deterministic behavior.

(1) delegation->cred doesn't need to be RCU protected as it's essentially an invariant refcounted structure. By the time we get to nfs_free_delegation(), the delegation is being released, so no one else should be attempting to use the saved credentials, and they can be cleared. However, since the list of delegations could still be under traversal at this point by such as nfs_client_return_marked_delegations(), the cred should be released in nfs_do_free_delegation() rather than in nfs_free_delegation(). Simply using rcu_assign_pointer() to clear it is insufficient as that doesn't stop the cred from being destroyed, and nor does calling put_rpccred() after call_rcu(), given that the latter is asynchronous. (2) nfs_detach_delegation_locked() and nfs_inode_set_delegation() should use rcu_derefence_protected() because they can only be called if nfs_client::cl_lock is held, and that guards against anyone changing nfsi->delegation under it. Furthermore, the barrier imposed by rcu_dereference() is superfluous, given that the spin_lock() is also a barrier. (3) nfs_detach_delegation_locked() is now passed a pointer to the nfs_client struct so that it can issue lockdep advice based on clp->cl_lock for (2). (4) nfs_inode_return_delegation_noreclaim() and nfs_inode_return_delegation() should use rcu_access_pointer() outside the spinlocked region as they merely examine the pointer and don't follow it, thus rendering unnecessary the need to impose a partial ordering over the one item of interest. These result in an RCU warning like the following: [ INFO: suspicious rcu_dereference_check() usage. ] --------------------------------------------------- fs/nfs/delegation.c:332 invoked rcu_dereference_check() without protection! other info that might help us debug this: rcu_scheduler_active = 1, debug_locks = 0 2 locks held by mount.nfs4/2281: #0: (&type->s_umount_key#34){+.+...}, at: [] deactivate_super+0x60/0x80 #1: (iprune_sem){+.+...}, at: [] invalidate_inodes+0x39/0x13a stack backtrace: Pid: 2281, comm: mount.nfs4 Not tainted 2.6.34-rc1-cachefs #110 Call Trace: [] lockdep_rcu_dereference+0xaa/0xb2 [] nfs_inode_return_delegation_noreclaim+0x5b/0xa0 [nfs] [] nfs4_clear_inode+0x11/0x1e [nfs] [] clear_inode+0x9e/0xf8 [] dispose_list+0x67/0x10e [] invalidate_inodes+0x11c/0x13a [] generic_shutdown_super+0x42/0xf4 [] kill_anon_super+0x11/0x4f [] nfs4_kill_super+0x3f/0x72 [nfs] [] deactivate_super+0x68/0x80 [] mntput_no_expire+0xbb/0xf8 [] release_mounts+0x9a/0xb0 [] put_mnt_ns+0x6a/0x79 [] nfs_follow_remote_path+0x5a/0x146 [nfs] [] ? nfs_do_root_mount+0x82/0x95 [nfs] [] nfs4_try_mount+0x75/0xaf [nfs] [] nfs4_get_sb+0x291/0x31a [nfs] [] vfs_kern_mount+0xb8/0x177 [] do_kern_mount+0x48/0xe8 [] do_mount+0x782/0x7f9 [] sys_mount+0x83/0xbe [] system_call_fastpath+0x16/0x1b Also on: fs/nfs/delegation.c:215 invoked rcu_dereference_check() without protection!

This driver turns out to be a copy of dm9601.c with symbols renamed and my copyright stripped. That aside, it did contain 1 functional change in dm_write_shared_word(), and after checking the datasheet the original value was indeed wrong (read versus write bits). On Michaels HW, this change bumps receive speed from ~30KB/s to ~900KB/s. On other devices the difference is less spectacular, but still significant (~30%).

After ethernet packet(s) arrived the receive descriptor is incremented by the number of frames processed. If another packet arrives while processing, this is processed in another call of ep93xx_rx. This second call leads that too many receive descriptors getting released. This fix increments, even in these case, the right number of processed receive descriptors.

Use a regular byte read instead for the address they live at (0x73). These are the only known chips living at this address on PC systems. For clarity, this fix should not be needed for kernels 2.6.30 and later, as we started instantiating the hwmon devices explicitly based on DMI data. Still, this fix is valuable in the following two cases: * Support for recent FSC chips on older kernels. The DMI-based device instantiation is more difficult to backport than the device support itself. * Case where the DMI-based device instantiation fails, whatever the reason. We fall back to probing in that case, so it should work.

Furthermore, the RCU check added in e7b0a61b7929632d36cf052d9e2820ef0a9c1bfe is incorrect as holding the spinlock on key_serial_lock is not grounds for assuming a keyring's pointer list can be read safely.

Skipping keyrings that have been reduced to a zero count seems the way to go. To this end, use atomic_inc_not_zero() to increment the usage count and skip the candidate keyring if that returns false. The following script _may_ cause the bug to happen, but there's no guarantee as the window of opportunity is small: #!/bin/sh LOOP=100000 USER=dummy_user /bin/su -c "exit;" $USER || { /usr/sbin/adduser -m $USER; add=1; } for ((i=0; i /dev/null" $USER done (( add == 1 )) && /usr/sbin/userdel -r $USER exit Note that the nominated user must not be in use. An alternative way of testing this may be: for ((i=0; i<100000; i++)) do keyctl session foo /bin/true || break done >&/dev/null as that uses a keyring named "foo" rather than relying on the user and user-session named keyrings.

Unfortunately BLOCK_PC commands are taken by SCSI to be SG_IO commands and the issuer expects to see and handle any returned errors, however trivial. This leads to a huge problem, because the block layer doesn't expect this to happen and any trivially retryable error on a barrier causes an immediate I/O error to the filesystem. The only real way to hack around this is to take the usual class of offending errors (unit attentions) and make them all retryable in the case of a REQ_HARDBARRIER. A correct fix would involve a rework of the entire block and SCSI submit system, and so is out of scope for a quick fix.

The BIOS guys hinted that The Other Leading OS ignores the fact that hardware owns the bit and sets it manually. In any case, an existing DMI table exists for machines where this defect is a known problem. Lenovo promise to fix their BIOS, but for folks who either won't or can't upgrade their BIOS, allow Linux to workaround the issue. https://bugzilla.kernel.org/show_bug.cgi?id=15407 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/532374 Confirmed by numerous testers in the launchpad bug that using acpi_sleep=sci_force_enable fixes the issue.

Change ipv6_icmp_error() and ipv6_local_error() to set skb->protocol to htons(ETH_P_IPV6) so that ipv6_recv_error() knows the address sitting right after the extended error is IPv6, else it will incorrectly map the first octet into an IPv4-mapped IPv6 address in the cmsg structure returned in a recvmsg() call to obtain the error.

That commit made PNPACPI include bridge windows as PNP resources, and PNP resource assignment treats any enabled overlapping PNP resources as conflicts. Since PCI host bridge windows typically include most of the I/O port space, this makes PNP port assigments fail. The PCI host bridge driver will eventually use those PNP window resources, so we should make PNP ignore them when checking for conflicts.

Here is the corresponding code which describe it. + int align = ~(line_length - 1); + end = ((end & align) == end) ? end - line_length : end & align; a) end is aligned: it is necessary to subtruct line length because we don't want to work with next cacheline b) end address is not aligned: Just align it to be ready for ASM code.

APIC ids must therefore be mapped to the lowest node ids to maintain generic kernel use of functions such as cpu_to_node() that determine device affinity. For example, if a device has proximity to physical node 1, for instance, and a cpu happens to be mapped to a higher emulated node id 8, the proximity may not be correctly determined by comparison in generic code even though the cpu may be truly local and allocated on physical node 1. When this happens, the true topology of the machine isn't accurately represented in the emulated environment; although this isn't critical to the system's uptime, any generic code that is NUMA aware benefits from the physical topology being accurately represented. This can affect any system that maps multiple APIC ids to a single node and is booted with numa=fake=N where N is greater than the number of physical nodes.

Reverted the old fix and fixed the problem in the mxb driver instead. Tested on mxb and budget-av cards. The real problem is that the saa7146 framework has separate probe() and attach() driver callbacks which should be rolled into one. This is now done for the mxb driver, but others should do the same. Lack of hardware makes this hard to do, though. I hope to get hold of some hexium cards and then I can try to improve the framework to prevent this from happening again.

Some time ago we stopped the clean/active metadata updates from being written to a 'spare' device in most cases so that it could spin down and say spun down. Device failure/removal etc are still recorded on spares. However commit 51d5668cb2e3fd1827a55 broke this 50% of the time, depending on whether the event count is even or odd. The change log entry said: This means that the alignment between 'odd/even' and 'clean/dirty' might take a little longer to attain, how ever the code makes no attempt to create that alignment, so it could take arbitrarily long. So when we find that clean/dirty is not aligned with odd/even, force a second metadata-update immediately. There are already cases where a second metadata-update is needed immediately (e.g. when a device fails during the metadata update). We just piggy-back on that.

Then we start that process, but the AP doesn't respond. While we're still waiting for an AP response, userspace asks for a deauth. We do the deauth, but don't abort the association work. Then once the association work times out we tell cfg80211, but it no longer wants to know since for all it is concerned we accepted the deauth that also kills the association attempt. Fix this by, upon receipt of deauth request, removing the association work and continuing to send the deauth. Unfortunately the user reporting the issue is not able to reproduce this problem anymore and cannot verify this fix. This seems like a well understood issue though and I thus present the patch.

Unfortunately, this optimization had a bug where it zeroed one key variable for new use, that is needed for the analysis. The fix is simple, zero the variable after doing the work from the previous idle. During the audit of the code that found this issue, another issue was also found; the ->measured_us data structure member is never set, a local variable is always used instead.

In case new multicast routing requests come in faster than the expiration timeout occurs (e.g. zap through multicast TV streams), the timer is prevented from being called at time for already existing entries. As the single timer is resetted to default whenever a new entry is made, the timeout for existing unresolved entires are missed and/or not updated. As a consequence new requests are denied when the limit of unresolved entries has been reached because old entries live longer than they are supposed to. The solution is to reset the timer only for the first unresolved entry in the multicast routing cache. All other timers are already set and updated correctly within the timer function itself by now.

(2) Retirement of the old object is done asynchronously - so the lookup/create to generate the new object may be done first. This can be a problem as the old object and the new object must exist at the same point in the backing filesystem (i.e. they must have the same pathname). (3) The lookup for the new object sees that a backing file already exists, checks to see whether it is valid and sees that it isn't. It then deletes that file and creates a new one on disk. (4) The retirement phase for the old file is then performed. It tries to delete the dentry it has, but ext4_unlink() returns -EIO because the inode attached to that dentry no longer matches the inode number associated with the filename in the parent directory.

It turns out that it isn't reliably so. Samba, in particular, will just put the st_ino in the uniqueid field when unix extensions are enabled. When a share spans multiple filesystems, it's quite possible that there will be collisions. This is a server bug, but when the inodes in question are a directory (as is often the case) and there is a collision with the root inode of the mount, the result is a kernel panic on umount. Fix this by checking explicitly for directory inodes with the same uniqueid. If that is the case, then we can assume that using server inode numbers will be a problem and that they should be disabled.

Commit c44972f1 ("procfs: disable per-task stack usage on NOMMU") was applied to fix the NO_MMU case. Commit 89240ba0 ("x86, fs: Fix x86 procfs stack information for threads on 64-bit") was applied to fix a bug in ia32 executables being loaded. Commit 9ebd4eba7 ("procfs: fix /proc//stat stack pointer for kernel threads") was applied to fix a bug which had kernel threads printing a userland stack address. Commit 1306d603f ('proc: partially revert "procfs: provide stack information for threads"') was then applied to revert the stack pages being used to solve a significant performance regression. This patch nearly undoes the effect of all these patches. The reason for reverting these is it provides an unusable value in field 28. For x86_64, a fork will result in the task->stack_start value being updated to the current user top of stack and not the stack start address. This unpredictability of the stack_start value makes it worthless. That includes the intended use of showing how much stack space a thread has. Other architectures will get different values. As an example, ia64 gets 0. The do_fork() and copy_process() functions appear to treat the stack_start and stack_size parameters as architecture specific. I only partially reverted c44972f1 ("procfs: disable per-task stack usage on NOMMU") . If I had completely reverted it, I would have had to change mm/Makefile only build pagewalk.o when CONFIG_PROC_PAGE_MONITOR is configured. Since I could not test the builds without significant effort, I decided to not change mm/Makefile. I only partially reverted 89240ba0 ("x86, fs: Fix x86 procfs stack information for threads on 64-bit") . I left the KSTK_ESP() change in place as that seemed worthwhile.

For shared mappings, these pages are reserved before mmap() returns success and for private mappings, the caller process is guaranteed and a child process that cannot get the pages gets killed with sigbus. An application that uses MAP_NORESERVE gets no reservations and mmap() will always succeed at the risk the page will not be available at fault time. This might be used for example on very large sparse mappings where the developer is confident the necessary huge pages exist to satisfy all faults even though the whole mapping cannot be backed by huge pages. Unfortunately, if an allocation does fail, VM_FAULT_OOM is returned to the fault handler which proceeds to trigger the OOM-killer. This is unhelpful. Even without hugetlbfs mounted, a user using mmap() can trivially trigger the OOM-killer because VM_FAULT_OOM is returned (will provide example program if desired - it's a whopping 24 lines long). It could be considered a DOS available to an unprivileged user. This patch alters hugetlbfs to kill a process that uses MAP_NORESERVE where huge pages were not available with SIGBUS instead of triggering the OOM killer. This change affects hugetlb_cow() as well. I feel there is a failure case in there, but I didn't create one. It would need a fairly specific target in terms of the faulting application and the hugepage pool size. The hugetlb_no_page() path is much easier to hit but both might as well be closed.

But Andrew Morton pointed out that the fix doesn't seems sane and it was just for hidining lockdep messages. This is a patch for do proper things. Checking again, all places, accessing without rcu_read_lock, that commit fixies was intentional.... all callers of css_id() has reference count on it. So, it's not necessary to be under rcu_read_lock(). Considering again, we can use rcu_dereference_check for css_id(). We know css->id is valid if css->refcnt > 0. (css->id never changes and freed after css->refcnt going to be 0.) This patch makes use of rcu_dereference_check() in css_id/depth and remove unnecessary rcu-read-lock added by the commit.

The symptom was that an interrupt would occur late in the exit path when the MSR[RI] (recoverable interrupt) bit was clear. Interrupts should be hard-disabled at this point but they were enabled. Because the interrupt was not recoverable the system panicked. The reason is that the exception exit path was calling perf_event_do_pending after hard-disabling interrupts, and perf_event_do_pending will re-enable interrupts. The simplest and cleanest fix for this is to use the same mechanism that 32-bit powerpc does, namely to cause a self-IPI by setting the decrementer to 1. This means we can remove the tests in the exception exit path and raw_local_irq_restore. This also makes sure that the call to perf_event_do_pending from timer_interrupt() happens within irq_enter/irq_exit. (Note that calling perf_event_do_pending from timer_interrupt does not mean that there is a possible 1/HZ latency; setting the decrementer to 1 ensures that the timer interrupt will happen immediately, i.e. within one timebase tick, which is a few nanoseconds or 10s of nanoseconds.)

The wait condition checks the status and devlist fields of the cqr to determine if it is safe to continue. This evaluation may return true, although the tasklet has not finished processing of the cqr and the callback function has not been called yet. When the callback is finally called, the data in the cqr may already be invalid. The sleep_on wait condition needs a safe way to determine if the tasklet has finished processing. Use the callback_data field of the cqr to store a token, which is set by the callback function itself.

Tsirkin" Date: Tue, 11 May 2010 19:44:17 +0300 Subject: [PATCH 848/897] vhost: fix barrier pairing According to memory-barriers.txt, an smp memory barrier in guest should always be paired with an smp memory barrier in host, and I quote "a lack of appropriate pairing is almost certainly an error". In case of vhost, failure to flush out used index update before looking at the interrupt disable flag could result in missed interrupts, resulting in networking hang under stress. This might happen when flags read bypasses used index write. So we see interrupts disabled and do not interrupt, at the same time guest writes flags value to enable interrupt, reads an old used index value, thinks that used ring is empty and waits for interrupt. Note: the barrier we pair with here is in drivers/virtio/virtio_ring.c, function vring_enable_cb. Signed-off-by: Michael S.

This seems to be what was intended in the undo code. What was done instead, was to look for a sem count of zero - this is an impossible situation, given that at least one thread is known to be queued on the semaphore. The code might be correct as written, but it's hard to reason about and it's not what was intended (otherwise the goto out would have been unconditional). Go for checking the active count - the alternative is not worth the headache.

With dma buffers located right next to msg and xfer fields, cache lines correctly flushed in preparation for dma usage may be polluted again when writing to fields in the same cache line. Make sure cache fields used with dma do not share cache lines with fields changed during dma handling. As both fields are part of a struct that is allocated via kzalloc, thus cache aligned, moving the fields to the 1st position and insert padding for alignment does the job.

That conversion would still succeed but the next conversion will see the completion that was signalled by the interrupt for the previous conversion and therefore not wait for the AUXADC conversion to run, causing it to report failure. Provide a simple, non-invasive cleanup by using try_wait_for_completion() to ensure that the completion is not signalled before we wait. Since the AUXADC is run within a mutex we know there can only have been at most one AUXADC interrupt outstanding. A more involved change should follow for the next merge window.

Since the RX FIFO has 32 entries, when CTS is raised, the FIFO already is full. However, some serial port devices first empty their TX FIFO before stopping when CTS is raised, resulting in lost chars. This patch sets the trigger level lower so that other chars arrive after CTS is raised, there is still room for 16 of them.

The fixed-size BAR capability lives in the extended configuration space, and thus is not applicable if the configuration space isn't appropriately sized. This fixes booting certain VMware configurations with CONFIG_MRST=y. Moorestown will add a fake PCI-X 266 capability to advertise the presence of extended configuration space.

To fix it right way we need to mark _dentry_ as unsuitable for mounting upon; new flag (DCACHE_CANT_MOUNT) is protected by d_flags and i_mutex on the inode in question. Set it (with dont_mount(dentry)) in unlink/rmdir/etc., check (with cant_mount(dentry)) in places in namespace.c that used to check for S_DEAD. Setting S_DEAD is still needed in places where we used to set it (for directories getting killed), since we rely on it for readdir/rmdir race prevention. 2) rename()/mount() protection has another bogosity - we unhash the target before we'd checked that it's not a mountpoint. Fixed. 3) ancient bogosity in pivot_root() - we locked i_mutex on the right directory, but checked S_DEAD on the different (and wrong) one. Noticed and fixed.

In odd corner cases, this can cause problems. For example, a case existed where a divide-by-zero exception was generated by the FPU, and the signal handler attempted to restore the FPU registers to their state before the exception occurred. In this particular setup, writing the old value to the FCSR register would cause another divide-by-zero exception to occur immediately. The solution is to change the ctc1 instruction emulator code to allow the Cause bits of the FCSR register to be writeable. This is the behaviour of the hardware that the code is emulating. This problem was found by Shane McDonald, but the credit for the fix goes to Kevin Kissell. In Kevin's words: I submit that the bug is indeed in that ctc_op: case of the emulator. The Cause bits (17:12) are supposed to be writable by that instruction, but the CTC1 emulation won't let them be updated by the instruction. I think that actually if you just completely removed lines 387-388 [...] things would work a good deal better. At least, it would be a more accurate emulation of the architecturally defined FPU. If I wanted to be really, really pedantic (which I sometimes do), I'd also protect the reserved bits that aren't necessarily writable.
