2009-09-16HWPOISON: Add poison check to page fault handlingAndi Kleen
Bail out early when hardware poisoned pages are found in page fault handling. Since they are poisoned they should not be mapped freshly into processes, because that would cause another (potentially deadly) machine check This is generally handled in the same way as OOM, just a different error code is returned to the architecture code. v2: Do a page unlock if needed (Fengguang Wu) Signed-off-by: Andi Kleen <ak@linux.intel.com>
2009-09-16HWPOISON: Add basic support for poisoned pages in fault handler v3Andi Kleen
- Add a new VM_FAULT_HWPOISON error code to handle_mm_fault. Right now architectures have to explicitely enable poison page support, so this is forward compatible to all architectures. They only need to add it when they enable poison page support. - Add poison page handling in swap in fault code v2: Add missing delayacct_clear_flag (Hidehiro Kawai) v3: Really use delayacct_clear_flag (Hidehiro Kawai) Signed-off-by: Andi Kleen <ak@linux.intel.com>
2009-09-16HWPOISON: Add new SIGBUS error codes for hardware poison signalsAndi Kleen
Add new SIGBUS codes for reporting machine checks as signals. When the hardware detects an uncorrected ECC error it can trigger these signals. This is needed for telling KVM's qemu about machine checks that happen to guests, so that it can inject them, but might be also useful for other programs. I find it useful in my test programs. This patch merely defines the new types. - Define two new si_codes for SIGBUS. BUS_MCEERR_AO and BUS_MCEERR_AR * BUS_MCEERR_AO is for "Action Optional" machine checks, which means that some corruption has been detected in the background, but nothing has been consumed so far. The program can ignore those if it wants (but most programs would already get killed) * BUS_MCEERR_AR is for "Action Required" machine checks. This happens when corrupted data is consumed or the application ran into an area which has been known to be corrupted earlier. These require immediate action and cannot just returned to. Most programs would kill themselves. - They report the address of the corruption in the user address space in si_addr. - Define a new si_addr_lsb field that reports the extent of the corruption to user space. That's currently always a (small) page. The user application cannot tell where in this page the corruption happened. AK: I plan to write a man page update before anyone asks.

2009-09-16HWPOISON: Add support for poison swap entries v2Andi Kleen
Memory migration uses special swap entry types to trigger special actions on page faults. Extend this mechanism to also support poisoned swap entries, to trigger poison handling on page faults. This allows follow-on patches to prevent processes from faulting in poisoned pages again. v2: Fix overflow in MAX_SWAPFILES (Fengguang Wu) v3: Better overflow fix (Hidehiro Kawai) Signed-off-by: Andi Kleen <ak@linux.intel.com>
2009-09-16HWPOISON: Export some rmap vma locking to outside worldAndi Kleen
Needed for later patch that walks rmap entries on its own. This used to be very frowned upon, but memory-failure.c does some rather specialized rmap walking and rmap has been stable for quite some time, so I think it's ok now to export it. Signed-off-by: Andi Kleen <ak@linux.intel.com>
2009-09-16HWPOISON: Add page flag for poisoned pagesAndi Kleen
Hardware poisoned pages need special handling in the VM and shouldn't be touched again. This requires a new page flag. Define it here. The page flags wars seem to be over, so it shouldn't be a problem to get a new one. v2: Add TestSetHWPoison (suggested by Johannes Weiner) Acked-by: Christoph Lameter <cl@linux.com> Signed-off-by: Andi Kleen <ak@linux.intel.com>

2009-09-16sched: Implement a gentler fair-sleepers featureIngo Molnar
Add back FAIR_SLEEPERS and GENTLE_FAIR_SLEEPERS. FAIR_SLEEPERS is the old logic: credit sleepers with their sleep time. GENTLE_FAIR_SLEEPERS dampens this a bit: 50% of their sleep time gets credited. The hope here is to still give the benefits of fair-sleepers logic (quick wakeups, etc.) while not allow them to have 100% of their sleep time as if they were running.

2009-09-15tcp: fix CONFIG_TCP_MD5SIG + CONFIG_PREEMPT timer BUG()Robert Varga
I have recently came across a preemption imbalance detected by: <4>huh, entered ffffffff80644630 with preempt_count 00000102, exited with 00000101? <0>------------[ cut here ]------------ <2>kernel BUG at /usr/src/linux/kernel/timer.c:664! <0>invalid opcode: 0000 [1] PREEMPT SMP with ffffffff80644630 being inet_twdr_hangman(). This appeared after I enabled CONFIG_TCP_MD5SIG and played with it a bit, so I looked at what might have caused it. One thing that struck me as strange is tcp_twsk_destructor(), as it calls tcp_put_md5sig_pool() -- which entails a put_cpu(), causing the detected imbalance.

2009-09-15nfsd41: Backchannel: Setup sequence informationRicardo Labiaga
Follows the model used by the NFS client. Setup the RPC prepare and done function pointers so that we can populate the sequence information if minorversion == 1. rpc_run_task() is then invoked directly just like existing NFS client operations do. nfsd4_cb_prepare() determines if the sequence information needs to be setup. If the slot is in use, it adds itself to the wait queue. nfsd4_cb_done() wakes anyone sleeping on the callback channel wait queue after our RPC reply has been received. It also sets the task message result pointer to NULL to clearly indicate we're done using it.

Follow the model we use in the client. Make the sequence arguments part of the regular RPC arguments. None of the callbacks that are soon to be implemented expect results that need to be passed back to the caller, so we don't define a separate RPC results structure. For session validation, the cb_sequence decoding will use a pointer to the sequence arguments that are part of the RPC argument.

2009-09-15nfsd4: fix null dereference creating nfsv4 callback clientJ. Bruce Fields
On setting up the callback to the client, we attempt to use the same authentication flavor the client did. We find an rpc cred to use by calling rpcauth_lookup_credcache(), which assumes that the given authentication flavor has a credentials cache. However, this is not required to be true--in particular, auth_null does not use one. Instead, we should call the auth's lookup_cred() method. Without this, a client attempting to mount using nfsv4 and auth_null triggers a null dereference. Cc: stable@kernel.org Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>

2009-09-15sparc: Kill PROM console driver.David S. Miller
Many years ago when this driver was written, it had a use, but these days it's nothing but trouble and distributions should not enable it in any situation. Pretty much every console device a sparc machine could see has a bonafide real driver, making the PROM console hack unnecessary. If any new device shows up, we should write a driver instead of depending upon this crutch to save us.
