* nfsd: use nfs client rpc callback programBenny Halevy2008-09-29
| | | | | | | | | | | | | | | since commit ff7d9756b501744540be65e172d27ee321d86103 "nfsd: use static memory for callback program and stats" do_probe_callback uses a static callback program (NFS4_CALLBACK) rather than the one set in clp->cl_callback.cb_prog as passed in by the client in setclientid (4.0) or create_session (4.1). This patches introduces rpc_create_args.prognumber that allows overriding program->number when creating rpc_clnt. Signed-off-by: Benny Halevy <bhalevy@panasas.com> Signed-off-by: J.

* lockd: address-family independent printable addressesChuck Lever2008-09-29
| | | | | | | | | | | | | | | | Knowing which source address is used for communicating with remote NLM services can be helpful for debugging configuration problems on hosts with multiple addresses. Keep the dprintk debugging here, but adapt it so it displays AF_INET6 addresses properly. There are also a couple of dprintk clean-ups as well. At some point we will aggregate the helpers that display presentation format addresses into a single set of shared helpers. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: J.

* SUNRPC: Support IPv6 when registering kernel RPC servicesChuck Lever2008-09-29
| | | | | | | | | | | | | | | | | | In order to advertise NFS-related services on IPv6 interfaces via rpcbind, the kernel RPC server implementation must use rpcb_v4_register() instead of rpcb_register(). A new kernel build option allows distributions to use the legacy v2 call until they integrate an appropriate user-space rpcbind daemon that can support IPv6 RPC services. I tried adding some automatic logic to fall back if registering with a v4 protocol request failed, but there are too many corner cases. So I just made it a compile-time switch that distributions can throw when they've replaced portmapper with rpcbind. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: J.

* SUNRPC: Simplify rpcb_register() APIChuck Lever2008-09-29
| | | | | | | | | | | | | | | Bruce suggested there's no need to expose the difference between an error sending the PMAP_SET request and an error reply from the portmapper to rpcb_register's callers. The user space equivalent of rpcb_register() is pmap_set(3), which returns a bool_t : either the PMAP set worked, or it didn't. Simple. So let's remove the "*okay" argument from rpcb_register() and rpcb_v4_register(), and simply return an error if any part of the call didn't work.

* Configure out file locking featuresThomas Petazzoni2008-09-29
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds the CONFIG_FILE_LOCKING option which allows to remove support for advisory locks. With this patch enabled, the flock() system call, the F_GETLK, F_SETLK and F_SETLKW operations of fcntl() and NFS support are disabled. These features are not necessarly needed on embedded systems.

* nfsd: permit unauthenticated stat of export rootJ. Bruce Fields2008-09-29
| | | | | | | | | | | | | | | | | | | | | | | | RFC 2623 section 2.3.2 permits the server to bypass gss authentication checks for certain operations that a client may perform when mounting. In the case of a client that doesn't have some form of credentials available to it on boot, this allows it to perform the mount unattended. (Presumably real file access won't be needed until a user with credentials logs in.) Being slightly more lenient allows lots of old clients to access krb5-only exports, with the only loss being a small amount of information leaked about the root directory of the export. This affects only v2 and v3; v4 still requires authentication for all access. Thanks to Peter Staubach testing against a Solaris client, which suggesting addition of v3 getattr, to the list, and to Trond for noting that doing so exposes no additional information.

Here's how it fails (same for all 3 drives): # dd if=/dev/sdc bs=512 count=1 skip=268435455 > /dev/null dd: reading `/dev/sdc': Input/output error 0+0 records in 0+0 records out 0 bytes (0 B) copied, 0.288033 seconds, 0.0 kB/s # dmesg ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x0 ata1.00: BMDMA stat 0x25 ata1.00: cmd c8/00:08:f8:ff:ff/00:00:00:00:00/ef tag 0 dma 4096 in res 51/04:08:f8:ff:ff/00:00:00:00:00/ef Emask 0x1 (device error) ata1.00: status: { DRDY ERR } ata1.00: error: { ABRT } ata1.00: configured for UDMA/33 ata1: EH complete ... After some investigations, it turned out this seems to be caused by misinterpretation of the ATA specification on LBA28 access. Following part is the code in question: === include/linux/ata.h === static inline int lba_28_ok(u64 block, u32 n_block) { /* check the ending block number */ return ((block + n_block - 1) < ((u64)1 << 28)) && (n_block <= 256); } HGST drive (sometimes) fails with LBA28 access of {block = 0xfffffff, n_block = 1}, and this behavior seems to be comformant. Other drives, including other HGST drives are not that strict, through. >From the ATA specification: (http://www.t13.org/Documents/UploadedDocuments/project/d1410r3b-ATA-ATAPI-6.pdf) 8.15.29 Word (61:60): Total number of user addressable sectors This field contains a value that is one greater than the total number of user addressable sectors (see 6.2). The maximum value that shall be placed in this field is 0FFFFFFFh. So the driver shouldn't use the value of 0xfffffff for LBA28 request as this exceeds maximum user addressable sector. The logical maximum value for LBA28 is 0xffffffe. The obvious fix is to cut "- 1" part, and the patch attached just do that. I've been using the patched kernel for about a month now, and the same fix is also floating on the net for some time. So I believe this fix works reliably. Just FYI, many Windows/Intel platform users also seems to be struck by this, and HGST has issued a note pointing to Intel ICH8/9 driver. "28-bit LBA command is being used to access LBAs 29-bits in length" http://www.hitachigst.com/hddt/knowtree.nsf/cffe836ed7c12018862565b000530c74/b531b8bce8745fb78825740f00580e23 Also, *BSDs seems to have similar fix included sometime around ~2004, through I have not checked out exact portion of the code.

The driver will attempt the switch to 8b mode for any new MSPro card, but not all of them support it.

The zoneref that is returned corresponds to the the next zone that is to be scanned, not the current one. It was intended to be treated as an opaque list. When the page allocator is scanning a zonelist, it marks elements in the zonelist corresponding to zones that are temporarily full. As the zonelist is being updated, it uses the cursor here; if (NUMA_BUILD) zlc_mark_zone_full(zonelist, z); This is intended to prevent rescanning in the near future but the zoneref cursor does not correspond to the zone that has been found to be full. This is an easy misunderstanding to make so this patch corrects the problem by changing zoneref cursor to be the current zone being scanned instead of the next one.

What this means is that doing echo 1 > /sys/devices/system/cpu/sched_mc_power_savings on a system with cpusets enabled will not take affect untill something changes in the cpuset setup (ie new sets created or deleted). This patch fixes restore correct behaviour where domains must be rebuilt in order to enable MC powersaving flags. Test on quad-core Core2 box with both CONFIG_CPUSETS and !CONFIG_CPUSETS.

The new clockevent ends up with clockevents_handle_noop as event handler, resulting in no timer activity. The problematic path seems to be * old device already has hrtimer_interrupt as the event_handler * new clockevent device registers with a higher rating * tick_check_new_device() is called * clockevents_exchange_device() gets called * old->event_handler is set to clockevents_handle_noop * tick_setup_device() is called for the new device * which sets new->event_handler using the old->event_handler which is noop. Change the ordering so that new device inherits the proper handler. This does not have any issue in normal case as most likely all the clockevent devices are setup before the highres switch. But, can potentially be affecting some corner case where HPET force detect happens after the highres switch. This was a problem with HPET in MSI mode code that we have been experimenting with.

The suspected reason for the problem is that signal_struct maintains it's own utime and stime (of exited tasks), these are not updated using the new task_utime() routine, hence sig->utime can go backwards and cause the same problem to occur (sig->utime, adds tsk->utime and not task_utime()). This patch fixes the problem TODO: using max(task->prev_utime, derived utime) works for now, but a more generic solution is to implement cputime_max() and use the cputime_gt() function for comparison.

This patch adds a V4L2_CAP_SENSOR_UPSIDE_DOWN flag to the capabilities flags, and sets this flag for the Philips SPC200NC cam (which has its sensor installed upside down). The same flag is also needed and added for the Philips SPC300NC. Together with a patch to libv4l which adds flipping the image in software this fixes the upside down display with the SPC200NC cam.

The pool lock is also promoted to irq-safe (suggested by Dan). It's necessary because free_pool is now called outside the irq disabled region. So we need to protect against an interrupt handler which calls debug_object_init().

This should fix the XORP build failure reported by Jose Calhariz, the debain package maintainer. Nothing originally in linux/mroute.h was exported to userspace ever, but some of this stuff started to be when it was moved into this new linux/pim.h, and that was wrong. If we didn't provide these definitions for 10 years we can reasonably expect that applications defined this stuff locally or used GLIBC headers providing the protocol definitions. And as such the only result of this can be conflict and userland build breakage. Signed-off-by: David S. Miller <davem@davemloft.net>

Since a separate lock is used to protect the RDMA_READ completion queue, a race exists between the dto_tasklet and the svc_rdma_recvfrom thread where the dto_tasklet sets the XPT_DATA bit and adds I/O to the read-completion queue. Concurrently, the recvfrom thread checks the generic queue, finds it empty and resets the XPT_DATA bit. A subsequent svc_xprt_enqueue will fail to enqueue the transport for I/O and cause the transport to "stall". The fix is to protect both lists with the same lock and set the XPT_DATA bit with this lock held. Signed-off-by: Tom Tucker <tom@opengridcomputing.com> Signed-off-by: J.
