2011-04-06x86, hibernate: Initialize mmu_cr4_features during bootH. Peter Anvin1-0/+5
Restore the initialization of mmu_cr4_features during boot, which was removed without comment in checkin e5f15b45ddf3afa2bbbb10c7ea34fb32b6de0a0e x86: Cleanup highmap after brk is concluded thereby breaking resume from hibernate. This restores previous functionality in approximately the same place, and corrects the reading of %cr4 on pre-CPUID hardware (%cr4 exists if and only if CPUID is supported.) However, part of the problem is that the hibernate suspend/resume sequence should manage the save/restore of %cr4 explicitly. Signed-off-by: H. Peter Anvin <[email protected]> Cc: Rafael J.

2011-04-06ipv6: Enable RFS sk_rxhash tracking for ipv6 sockets (v2)Neil Horman2-1/+6
properly record sk_rxhash in ipv6 sockets (v2) Noticed while working on another project that flows to sockets which I had open on a test systems weren't getting steered properly when I had RFS enabled. Looking more closely I found that: 1) The affected sockets were all ipv6 2) They weren't getting steered because sk->sk_rxhash was never set from the incomming skbs on that socket. This was occuring because there are several points in the IPv4 tcp and udp code which save the rxhash value when a new connection is established. Those calls to sock_rps_save_rxhash were never added to the corresponding ipv6 code paths. This patch adds those calls. Tested by myself to properly enable RFS functionalty on ipv6.

2011-04-06can: mcp251x: Allow pass IRQ flags through platform data.Enric Balletbo i Serra2-1/+4
When an interrupt occurs, the INT pin is driven low by the MCP251x controller (falling edge) but in some cases the INT pin can be connected to the MPU through a transistor or level translator which inverts this signal. In this case interrupt should be configured in rising edge. This patch adds support to pass the IRQ flags via mcp251x_platform_data.

2011-04-06KVM: move and fix substitue search for missing CPUID entriesAndre Przywara1-6/+25
If KVM cannot find an exact match for a requested CPUID leaf, the code will try to find the closest match instead of simply confessing it's failure. The implementation was meant to satisfy the CPUID specification, but did not properly check for extended and standard leaves and also didn't account for the index subleaf. Beside that this rule only applies to CPUID intercepts, which is not the only user of the kvm_find_cpuid_entry() function. So fix this algorithm and call it from kvm_emulate_cpuid(). This fixes a crash of newer Linux kernels as KVM guests on AMD Bulldozer CPUs, where bogus values were returned in response to a CPUID intercept.

2011-04-06KVM: fix XSAVE bit scanningAndre Przywara1-3/+3
When KVM scans the 0xD CPUID leaf for propagating the XSAVE save area leaves, it assumes that the leaves are contigious and stops at the first zero one. On AMD hardware there is a gap, though, as LWP uses leaf 62 to announce it's state save area. So lets iterate through all 64 possible leaves and simply skip zero ones to also cover later features.

2011-04-05inotify: fix double free/corruption of stuct userEric Paris2-26/+14
On an error path in inotify_init1 a normal user can trigger a double free of struct user. This is a regression introduced by a2ae4cc9a16e ("inotify: stop kernel memory leak on file creation failure"). We fix this by making sure that if a group exists the user reference is dropped when the group is cleaned up. We should not explictly drop the reference on error and also drop the reference when the group is cleaned up. The new lifetime rules are that an inotify group lives from inotify_new_group to the last fsnotify_put_group. Since the struct user and inotify_devs are directly tied to this lifetime they are only changed/updated in those two locations. We get rid of all special casing of struct user or user->inotify_devs. Signed-off-by: Eric Paris <[email protected]> Cc: [email protected] (2.6.37 and up) Signed-off-by: Linus Torvalds <[email protected]>

2011-04-05dm: improve block integrity supportMike Snitzer3-35/+93
The current block integrity (DIF/DIX) support in DM is verifying that all devices' integrity profiles match during DM device resume (which is past the point of no return). To some degree that is unavoidable (stacked DM devices force this late checking). But for most DM devices (which aren't stacking on other DM devices) the ideal time to verify all integrity profiles match is during table load. Introduce the notion of an "initialized" integrity profile: a profile that was blk_integrity_register()'d with a non-NULL 'blk_integrity' template. Add blk_integrity_is_initialized() to allow checking if a profile was initialized. Update DM integrity support to: - check all devices with _initialized_ integrity profiles match during table load; uninitialized profiles (e.g. for underlying DM device(s) of a stacked DM device) are ignored. - disallow a table load that would result in an integrity profile that conflicts with a DM device's existing (in-use) integrity profile - avoid clearing an existing integrity profile - validate all integrity profiles match during resume; but if they don't all we can do is report the mismatch (during resume we're past the point of no return) Signed-off-by: Mike Snitzer <[email protected]> Cc: Martin K.
