This adds support for hot adding and removing expanders, and its associated attached devices. When there is a change in topology, the fusion firmware sends the MPI_EVENT_SAS_DISCOVERY event to the driver. The driver will read firmware config pages to determine what changes took place, and refresh drivers view of the world stored in ioc->sas_topology. Here is the details of the action the driver does: (1) Expander Added : The mptsas_discovery_work workqueue is called. Config pages read, and ioc->sas_topology is refreshed. The sas_phy_add() is called for each phy of the expander. The expanders attached devices are added via sas_rphy_add(). Added end devices are handled within the MPT_ADD_DEVICE logic in mptsas_hotplug_work workqueue. (2) Expander Delete : The sas_rphy_delete() will be called for the top most compenent of the parent that the expander is attached to. The sas_rphy_delete call will delete all the children phys, rphys, and end devices. This is handled from mptsas_discovery_work workqueue. Signed-off-by:

Suppport for exposing hidden raid components for sg interface. The sdev->no_uld_attach flag will set set accordingly. The sas module supports adding/removing raid volumes using online storage management application interface. This patch rely's on patch's provided to me by Christoph Hellwig, that exports device_reprobe. I will post those patch's on behalf of Christoph. Signed-off-by:

This patch makes expanders appear as labelled objects with properties in the SAS tree. I've also modified the phy code to make expander phys appear labelled by host number, expander number and phy index. So, for my current config, you see something like this in sysfs: /sys/class/scsi_host/host1/device/phy-1:4/expander-1:0/phy-1-0:12/rphy-1:0-12/target1:0:1 And the expander properties are: jejb@sparkweed> cd /sys/class/sas_expander/expander-1\:0/ jejb@sparkweed> for f in *; do echo -n $f ": "; cat $f; done component_id : 29024 component_revision_id : 4 component_vendor_id : VITESSE device : cat: device: Is a directory level : 0 product_id : VSC7160 Eval Brd product_rev : 4 uevent : cat: uevent: Permission denied vendor_id : VITESSE Signed-off-by: -

- Disable the EDAC sysfs code. The sysfs interface that EDAC presents to user space needs more thought, and is likely to change substantially. Therefore disable it for now so users don't start depending on it in its current form. - Disable the default behavior of calling panic() when an uncorrectible error is detected (since for now, there is no sysfs interface that allows the user to configure this behavior).

Based on an original patch by Mike O'Connor and Greg Banks of SGI. Mike states: A normal user can panic an NFS client and cause a local DoS with 'judicious'(?) use of O_DIRECT. Any O_DIRECT write to an NFS file where the user buffer starts with a valid mapped page and contains an unmapped page, will crash in this way. I haven't followed the code, but O_DIRECT reads with similar user buffers will probably also crash albeit in different ways. Details: when nfs_get_user_pages() calls get_user_pages(), it detects and correctly handles get_user_pages() returning an error, which happens if the first page covered by the user buffer's address range is unmapped. However, if the first page is mapped but some subsequent page isn't, get_user_pages() will return a positive number which is less than the number of pages requested (this behaviour is sort of analagous to a short write() call and appears to be intentional). nfs_get_user_pages() doesn't detect this and hands off the array of pages (whose last few elements are random rubbish from the newly allocated array memory) to it's caller, whence they go to nfs_direct_write_seg(), which then totally ignores the nr_pages it's given, and calculates its own idea of how many pages are in the array from the user buffer length. Needless to say, when it comes to transmit those uninitialised page* pointers, we see a crash in the network stack. Signed-off-by:

This patch fixes alternate signal stack corruption among cloned threads with CLONE_SIGHAND (and CLONE_VM) for linux-2.6.16-rc6. The value of alternate signal stack is currently inherited after a call of clone(... CLONE_SIGHAND | CLONE_VM). But if sigaltstack is set by a parent thread, and then if multiple cloned child threads (+ parent threads) call signal handler at the same time, some threads may be conflicted - because they share to use the same alternative signal stack region. Finally they get sigsegv. It's an undesirable race condition. Note that child threads created from NPTL pthread_create() also hit this conflict when the parent thread uses sigaltstack, without my patch. To fix this problem, this patch clears the child threads' sigaltstack information like exec(). This behavior follows the SUSv3 specification. In SUSv3, pthread_create() says "The alternate stack shall not be inherited (when new threads are initialized)". It means that sigaltstack should be cleared when sigaltstack memory space is shared by cloned threads with CLONE_SIGHAND. Note that I chose "if (clone_flags & CLONE_SIGHAND)" line because: - If clone_flags line is not existed, fork() does not inherit sigaltstack. - CLONE_VM is another choice, but vfork() does not inherit sigaltstack. - CLONE_SIGHAND implies CLONE_VM, and it looks suitable. - CLONE_THREAD is another candidate, and includes CLONE_SIGHAND + CLONE_VM, but this flag has a bit different semantics. I decided to use CLONE_SIGHAND.

EM64T CPUs have somewhat weird error reporting for non canonical RIPs in SYSRET. We can't handle any exceptions there because the exception handler would end up running on the user stack which is unsafe. To avoid problems any code that might end up with a user touched pt_regs should return using int_ret_from_syscall. int_ret_from_syscall ends up using IRET, which allows safe exceptions.
