2006-06-25[PATCH] ftruncate does not always update m/ctimePeter Staubach
In the course of trying to track down a bug where a file mtime was not being updated correctly, it was discovered that the m/ctime updates were not quite being handled correctly for ftruncate() calls. Quoth SUSv3: open(2): If O_TRUNC is set and the file did previously exist, upon successful completion, open() shall mark for update the st_ctime and st_mtime fields of the file. truncate(2): Upon successful completion, if the file size is changed, this function shall mark for update the st_ctime and st_mtime fields of the file, and the S_ISUID and S_ISGID bits of the file mode may be cleared. ftruncate(2): Upon successful completion, if fildes refers to a regular file, the ftruncate() function shall mark for update the st_ctime and st_mtime fields of the file and the S_ISUID and S_ISGID bits of the file mode may be cleared. If the ftruncate() function is unsuccessful, the file is unaffected. The open(O_TRUNC) and truncate cases were being handled correctly, but the ftruncate case was being handled like the truncate case. The semantics of truncate and ftruncate don't quite match, so ftruncate needs to be handled slightly differently. The attached patch addresses this issue for ftruncate(2). My thanx to Stephen Tweedie and Trond Myklebust for their help in understanding the situation and semantics. Signed-off-by: Peter Staubach <staubach@redhat.com> Cc: "Stephen C.

2006-06-23[PATCH] vfs: add lock owner argument to flush operationMiklos Szeredi
Pass the POSIX lock owner ID to the flush operation. This is useful for filesystems which don't want to store any locking state in inode->i_flock but want to handle locking/unlocking POSIX locks internally. FUSE is one such filesystem but I think it possible that some network filesystems would need this also. Also add a flag to indicate that a POSIX locking request was generated by close(), so filesystems using the above feature won't send an extra locking request in this case.

2006-06-23[PATCH] VFS: Permit filesystem to perform statfs with a known root dentryDavid Howells
Give the statfs superblock operation a dentry pointer rather than a superblock pointer. This complements the get_sb() patch. That reduced the significance of sb->s_root, allowing NFS to place a fake root there. However, NFS does require a dentry to use as a target for the statfs operation. This permits the root in the vfsmount to be used instead. linux/mount.h has been added where necessary to make allyesconfig build successfully. Interest has also been expressed for use with the FUSE and XFS filesystems.

Also, add a comment, so that people who read the code understand why we do what looks like a no-op.

2006-04-18x86: don't allow tail-calls in sys_ftruncate[64]()Linus Torvalds
Gcc thinks it owns the incoming argument stack, but that's not true for "asmlinkage" functions, and it corrupts the caller-set-up argument stack when it pushes the third argument onto the stack. Which can result in %ebx getting corrupted in user space. Now, normally nobody sane would ever notice, since libc will save and restore %ebx anyway over the system call, but it's still wrong. I'd much rather have "asmlinkage" tell gcc directly that it doesn't own the stack, but no such attribute exists, so we're stuck with our hacky manual "prevent_tail_call()" macro once more (we've had the same issue before with sys_waitpid() and sys_wait4()).

2006-03-23[PATCH] Shrinks sizeof(files_struct) and better layoutEric Dumazet
1) Reduce the size of (struct fdtable) to exactly 64 bytes on 32bits platforms, lowering kmalloc() allocated space by 50%. 2) Reduce the size of (files_struct), using a special 32 bits (or 64bits) embedded_fd_set, instead of a 1024 bits fd_set for the close_on_exec_init and open_fds_init fields. This save some ram (248 bytes per task) as most tasks dont open more than 32 files. D-Cache footprint for such tasks is also reduced to the minimum. 3) Reduce size of allocated fdset. Currently two full pages are allocated, that is 32768 bits on x86 for example, and way too much. The minimum is now L1_CACHE_BYTES. UP and SMP should benefit from this patch, because most tasks will touch only one cache line when open()/close() stdin/stdout/stderr (0/1/2), (next_fd, close_on_exec_init, open_fds_init, fd_array[0 .. 2] being in the same cache line) Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-03-20[PATCH] Collect more inode information during syscall processing.Amy Griffis
This patch augments the collection of inode info during syscall processing. It represents part of the functionality that was provided by the auditfs patch included in RHEL4. Specifically, it: - Collects information for target inodes created or removed during syscalls. Previous code only collects information for the target inode's parent. - Adds the audit_inode() hook to syscalls that operate on a file descriptor (e.g. fchown), enabling audit to do inode filtering for these calls. - Modifies filtering code to check audit context for either an inode # or a parent inode # matching a given rule. - Modifies logging to provide inode # for both parent and child. - Protect debug info from NULL audit_names.name.

2006-01-18[PATCH] vfs: *at functions: coreUlrich Drepper
Here is a series of patches which introduce in total 13 new system calls which take a file descriptor/filename pair instead of a single file name. These functions, openat etc, have been discussed on numerous occasions. They are needed to implement race-free filesystem traversal, they are necessary to implement a virtual per-thread current working directory (think multi-threaded backup software), etc. We have in glibc today implementations of the interfaces which use the /proc/self/fd magic. But this code is rather expensive. Here are some results (similar to what Jim Meyering posted before). The test creates a deep directory hierarchy on a tmpfs filesystem. Then rm -fr is used to remove all directories. Without syscall support I get this: real 0m31.921s user 0m0.688s sys 0m31.234s With syscall support the results are much better: real 0m20.699s user 0m0.536s sys 0m20.149s The interfaces are for obvious reasons currently not much used. But they'll be used. coreutils (and Jeff's posixutils) are already using them. Furthermore, code like ftw/fts in libc (maybe even glob) will also start using them. I expect a patch to make follow soon. Every program which is walking the filesystem tree will benefit.

2006-01-08[PATCH] Fix some problems with truncate and mtime semantics.NeilBrown
SUS requires that when truncating a file to the size that it currently is: truncate and ftruncate should NOT modify ctime or mtime O_TRUNC SHOULD modify ctime and mtime. Currently mtime and ctime are always modified on most local filesystems (side effect of ->truncate) or never modified (on NFS). With this patch: ATTR_CTIME|ATTR_MTIME are sent with ATTR_SIZE precisely when an update of these times is required whether size changes or not (via a new argument to do_truncate). This allows NFS to do the right thing for O_TRUNC. inode_setattr nolonger forces ATTR_MTIME|ATTR_CTIME when the ATTR_SIZE sets the size to it's current value. This allows local filesystems to do the right thing for f?truncate. Also, the logic in inode_setattr is changed a bit so there are two return points. One returns the error from vmtruncate if it failed, the other returns 0 (there can be no other failure). Finally, if vmtruncate succeeds, and ATTR_SIZE is the only change requested, we now fall-through and mark_inode_dirty. If a filesystem did not have a ->truncate function, then vmtruncate will have changed i_size, without marking the inode as 'dirty', and I think this is wrong.

2005-09-13[PATCH] open returns ENFILE but creates file anywayPeter Staubach
When open(O_CREAT) is called and the error, ENFILE, is returned, the file may be created anyway. This is counter intuitive, against the SUS V3 specification, and may cause applications to misbehave if they are not coded correctly to handle this semantic. The SUS V3 specification explicitly states "No files shall be created or modified if the function returns -1.". The error, ENFILE, is used to indicate the system wide open file table is full and no more file structs can be allocated. This is due to an ordering problem. The entry in the directory is created before the file struct is allocated. If the allocation for the file struct fails, then the system call must return an error, but the directory entry was already created and can not be safely removed. The solution to this situation is relatively easy. The file struct should be allocated before the directory entry is created. If the allocation fails, then the error can be returned directly. If the creation of the directory entry fails, then the file struct can be easily freed.

2005-09-09[PATCH] files: files struct with RCUDipankar Sarma
Patch to eliminate struct files_struct.file_lock spinlock on the reader side and use rcu refcounting rcuref_xxx api for the f_count refcounter. The updates to the fdtable are done by allocating a new fdtable structure and setting files->fdt to point to the new structure. The fdtable structure is protected by RCU thereby allowing lock-free lookup. For fd arrays/sets that are vmalloced, we use keventd to free them since RCU callbacks can't sleep. A global list of fdtable to be freed is not scalable, so we use a per-cpu list. If keventd is already handling the current cpu's work, we use a timer to defer queueing of that work. Since the last publication, this patch has been re-written to avoid using explicit memory barriers and use rcu_assign_pointer(), rcu_dereference() premitives instead. This required that the fd information is kept in a separate structure (fdtable) and updated atomically.

2005-07-12[PATCH] inotifyRobert Love
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.

2005-06-23[PATCH] Don't force O_LARGEFILE for 32 bit processes on ia64Yoav Zach
In ia64 kernel, the O_LARGEFILE flag is forced when opening a file. This is problematic for execution of 32 bit processes, which are not largefile aware, either by SW emulation or by HW execution. For such processes, the problem is two-fold: 1) When trying to open a file that is larger than 4G the operation should fail, but it's not 2) Writing to offset larger than 4G should fail, but it's not The proposed patch takes advantage of the way 32 bit processes are identified in ia64 systems. Such processes have PER_LINUX32 for their personality. With the patch, the ia64 kernel will not enforce the O_LARGEFILE flag if the current process has PER_LINUX32 set.
