2005-07-14[PATCH] uml: allow building as 32-bit binary on 64bit hostPaolo 'Blaisorblade' Giarrusso4-21/+31
This patch makes the command: make ARCH=um SUBARCH=i386 work on x86_64 hosts (with support for building 32-bit binaries). This is especially needed since 64-bit UMLs don't support 32-bit emulation for guest binaries, currently. This has been tested in all possible cases and works. Only exception is that I've built but not tested a 64-bit binary, because I hadn't a 64-bit filesystem available.

2005-07-14[PATCH] uml: workaround host bug in "TT mode vs. NPTL link fix"Paolo 'Blaisorblade' Giarrusso2-2/+2
A big bug has been diagnosed on hosts running the SKAS patch and built with CONFIG_REGPARM, due to some missing prevent_tail_call(). On these hosts, this workaround is needed to avoid triggering that bug, because "to" is kept by GCC only in EBX, which is corrupted at the return of mmap2(). Since to trigger this bug int 0x80 must be used when doing the call, it rarely manifests itself, so I'd prefer to get this merged to workaround that host bug, since it should cause no functional change. Still, you might prefer to drop it, I'll leave this to you.

Just read the access_ok check on fp which is NULL, or the pointer arithmetic below which should be done with a cast to void*: frame = (struct rt_sigframe __user *) round_down(stack_top - sizeof(struct rt_sigframe), 16) - 8; The code shows clearly that has been taken from arch/x86_64/kernel/signal.c:setup_rt_frame(), maybe in a bit of a hurry.

Add special case for the POSIX_FADV_DONTNEED and POSIX_FADV_NOREUSE hint values for s390-64. The user space values in the s390-64 glibc headers for these two defines have always been 6 and 7 instead of 4 and 5. All 64 bit applications therefore use the "wrong" values. To get these applications working without recompiling the kernel needs to accept the "wrong" values. Since the values for s390-31 are 4 and 5 the compat wrapper for fadvise64 and fadvise64_64 need to rewrite the values for 31 bit system calls.

2005-07-13[PATCH] Fix soft lockup due to NTFS: VFS part and explanationAnton Altaparmakov2-6/+42
Something has changed in the core kernel such that we now get concurrent inode write outs, one e.g via pdflush and one via sys_sync or whatever. This causes a nasty deadlock in ntfs. The only clean solution unfortunately requires a minor vfs api extension. First the deadlock analysis: Prerequisive knowledge: NTFS has a file $MFT (inode 0) loaded at mount time. The NTFS driver uses the page cache for storing the file contents as usual. More interestingly this file contains the table of on-disk inodes as a sequence of MFT_RECORDs. Thus NTFS driver accesses the on-disk inodes by accessing the MFT_RECORDs in the page cache pages of the loaded inode $MFT. The situation: VFS inode X on a mounted ntfs volume is dirty. For same inode X, the ntfs_inode is dirty and thus corresponding on-disk inode, which is as explained above in a dirty PAGE_CACHE_PAGE belonging to the table of inodes ($MFT, inode 0). What happens: Process 1: sys_sync()/umount()/whatever... calls __sync_single_inode() for $MFT -> do_writepages() -> write_page for the dirty page containing the on-disk inode X, the page is now locked -> ntfs_write_mst_block() which clears PageUptodate() on the page to prevent anyone else getting hold of it whilst it does the write out (this is necessary as the on-disk inode needs "fixups" applied before the write to disk which are removed again after the write and PageUptodate is then set again). It then analyses the page looking for dirty on-disk inodes and when it finds one it calls ntfs_may_write_mft_record() to see if it is safe to write this on-disk inode. This then calls ilookup5() to check if the corresponding VFS inode is in icache(). This in turn calls ifind() which waits on the inode lock via wait_on_inode whilst holding the global inode_lock. Process 2: pdflush results in a call to __sync_single_inode for the same VFS inode X on the ntfs volume. This locks the inode (I_LOCK) then calls write-inode -> ntfs_write_inode -> map_mft_record() -> read_cache_page() of the page (in page cache of table of inodes $MFT, inode 0) containing the on-disk inode. This page has PageUptodate() clear because of Process 1 (see above) so read_cache_page() blocks when tries to take the page lock for the page so it can call ntfs_read_page(). Thus Process 1 is holding the page lock on the page containing the on-disk inode X and it is waiting on the inode X to be unlocked in ifind() so it can write the page out and then unlock the page. And Process 2 is holding the inode lock on inode X and is waiting for the page to be unlocked so it can call ntfs_readpage() or discover that Process 1 set PageUptodate() again and use the page. Thus we have a deadlock due to ifind() waiting on the inode lock. The only sensible solution: NTFS does not care whether the VFS inode is locked or not when it calls ilookup5() (it doesn't use the VFS inode at all, it just uses it to find the corresponding ntfs_inode which is of course attached to the VFS inode (both are one single struct); and it uses the ntfs_inode which is subject to its own locking so I_LOCK is irrelevant) hence we want a modified ilookup5_nowait() which is the same as ilookup5() but it does not wait on the inode lock. Without such functionality I would have to keep my own ntfs_inode cache in the NTFS driver just so I can find ntfs_inodes independent of their VFS inodes which would be slow, memory and cpu cycle wasting, and incredibly stupid given the icache already exists in the VFS. Below is a patch that does the ilookup5_nowait() implementation in fs/inode.c and exports it. ilookup5_nowait.diff: Introduce ilookup5_nowait() which is basically the same as ilookup5() but it does not wait on the inode's lock (i.e. it omits the wait_on_inode() done in ifind()). This is needed to avoid a nasty deadlock in NTFS. Signed-off-by: Anton Altaparmakov <aia21@cantab.net> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-07-12[PATCH] inotifyRobert Love24-67/+1639
inotify is intended to correct the deficiencies of dnotify, particularly its inability to scale and its terrible user interface: * dnotify requires the opening of one fd per each directory that you intend to watch. This quickly results in too many open files and pins removable media, preventing unmount. * dnotify is directory-based. You only learn about changes to directories. Sure, a change to a file in a directory affects the directory, but you are then forced to keep a cache of stat structures. * dnotify's interface to user-space is awful. Signals? inotify provides a more usable, simple, powerful solution to file change notification: * inotify's interface is a system call that returns a fd, not SIGIO. You get a single fd, which is select()-able. * inotify has an event that says "the filesystem that the item you were watching is on was unmounted." * inotify can watch directories or files. Inotify is currently used by Beagle (a desktop search infrastructure), Gamin (a FAM replacement), and other projects. See Documentation/filesystems/inotify.txt.

2005-07-12reiserfs: run scripts/Lindent on reiserfs codeLinus Torvalds30-22663/+24429
This was a pure indentation change, using: scripts/Lindent fs/reiserfs/*.c include/linux/reiserfs_*.h to make reiserfs match the regular Linux indentation style. As Jeff Mahoney <jeffm@suse.com> writes: The ReiserFS code is a mix of a number of different coding styles, sometimes different even from line-to-line. Since the code has been relatively stable for quite some time and there are few outstanding patches to be applied, it is time to reformat the code to conform to the Linux style standard outlined in Documentation/CodingStyle. This patch contains the result of running scripts/Lindent against fs/reiserfs/*.c and include/linux/reiserfs_*.h. There are places where the code can be made to look better, but I'd rather keep those patches separate so that there isn't a subtle by-hand hand accident in the middle of a huge patch. To be clear: This patch is reformatting *only*. A number of patches may follow that continue to make the code more consistent with the Linux coding style. Hans wasn't particularly enthusiastic about these patches, but said he wouldn't really oppose them either. Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Instead of setting a multipath 'suspended' flag which would have to be reset if an error occurs during the process, save the previous queueing state and leave userspace to restore if it wishes.

2005-07-12[PATCH] device-mapper multipath: Flush workqueue when destroyingAlasdair G Kergon1-0/+2
The multipath destructor must flush its workqueue. Otherwise items that reference the destroyed object could remain.

2005-07-12[IA64] Altix pcibus_to_node implementationChristoph Lameter6-9/+46
The Altix subarch does not provide node information via ACPI. Instead hooks are used to fixup pci structures. This patch determines the nodes for Altix PCI busses. Remote Bridges: --------------- Altix supports remote I/O nodes without memory or processors but with bridges. The TIOCA type of bridge is an AGP bridge and the PROM provides information about the closest node. That information will be returned by pcibus_to_node. The TIOCP remote bridge type is a PCI bridge but the PROM does not provide a closest node id. pcibus_to_node will return -1 for devices on those bridges meaning that device control structures may be allocated on any node. Safeguard: ---------- Should the fixups result in invalid node information for a pci controller then a warning will be printed and pcibus_to_node will return -1. This patch also fixes the "FIXME" in sn_dma_alloc_coherent. This means that dma_alloc_coherent will now use alloc_pages_node to allocate memory local to the node that the PCI device is connected to.
