The Coverity checker spotted the following bug in dup_namespace(): <-- snip --> if (!new_ns->root) { up_write(&namespace_sem); kfree(new_ns); goto out; } ... out: return new_ns; <-- snip --> Callers expect a non-NULL result to not be freed.

2006-03-14[PATCH] Consistent capabilites associated with MPOL_MOVE_ALLChristoph Lameter
It seems that setting scheduling policy and priorities is also the kind of thing that might be performed in apps that also use the NUMA API, so it would seem consistent to use CAP_SYS_NICE for NUMA also. So use CAP_SYS_NICE for controlling migration permissions.

2006-03-14[PATCH] page migration: fail if page is in a vma flagged VM_LOCKEDChristoph Lameter
page migration currently simply retries a couple of times if try_to_unmap() fails without inspecting the return code. However, SWAP_FAIL indicates that the page is in a vma that has the VM_LOCKED flag set (if ignore_refs ==1). We can check for that return code and avoid retrying the migration. migrate_page_remove_references() now needs to return a reason why the failure occured. So switch migrate_page_remove_references to use -Exx style error messages.

* git://oss.sgi.com:8090/oss/git/rc-fixes: Fix a direct I/O locking issue revealed by the new mutex code.
2006-03-15Fix a direct I/O locking issue revealed by the new mutex code.Nathan Scott
Affects only XFS (i.e. DIO_OWN_LOCKING case) - currently it is not possible to get i_mutex locking correct when using DIO_OWN direct I/O locking in a filesystem due to indeterminism in the possible return code/lock/unlock combinations. This can cause a direct read to attempt a double i_mutex unlock inside XFS. We're now ensuring __blockdev_direct_IO always exits with the inode i_mutex (still) held for a direct reader. Tested with the three different locking modes (via direct block device access, ext3 and XFS) - both reading and writing; cannot find any regressions resulting from this change, and it clearly fixes the mutex_unlock warning originally reported here: http://marc.theaimsgroup.com/?l=linux-kernel&m=114189068126253&w=2 Signed-off-by: Nathan Scott <nathans@sgi.com> Acked-by: Christoph Hellwig <hch@lst.de>

2006-03-14[PATCH] NFS: Fix a potential panic in O_DIRECTTrond Myklebust
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.

2006-03-14[PATCH] Fix sigaltstack corruption among cloned threadsGOTO Masanori
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.
