| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | patch 2ea55c01e0c5dfead8699484b0bae2a375b1f61c fixed CIFS clobbering the global fops structure for some per mount setting, by duplicating and having 2 fops structs. However the write to the fops was left behind, which is a NOP in practice (due to the fact that we KNOW the fops has that field set to NULL already due to the duplication). So remove it... In addition, another instance of the same bug was forgotten in november. Signed-off-by: Arjan van de Ven <arjan@infradead.org> Signed-off-by: Steve French <sfrench@us.ibm.com>

It requires no core kernel changes except the added scrub functions already posted. The goal is to merge further functionality only after the core code is accepted and proven in the base kernel, and only at the point the upstream extras are really ready to merge. From: doug thompson <norsk5@xmission.com> This converts EDAC to sysfs and is the final chunk neccessary before EDAC has a stable user space API and can be considered for submission into the base kernel.

That means rewriting memory locations atomically with respect to all CPUs _and_ bus masters. That means we can't use atomic_add(foo, 0) as it gets optimised for non-SMP This adds a function to include/asm-foo/atomic.h for the platforms currently supported which implements a scrub of a mapped block. It also adjusts a few other files include order where atomic.h is included before types.h as this now causes an error as atomic_scrub uses u32.

These system calls have to change the signal mask during their operation, and signal handlers must be invoked using the new, temporary signal mask. The old signal mask must be restored either upon successful exit from the system call, or upon returning from the invoked signal handler if the system call is interrupted. We can't simply restore the original signal mask and return to userspace, since the restored signal mask may actually block the signal which interrupted the system call. The TIF_RESTORE_SIGMASK flag deals with this by causing the syscall exit path to trap into do_signal() just as TIF_SIGPENDING does, and by causing do_signal() to use the saved signal mask instead of the current signal mask when setting up the stack frame for the signal handler -- or by causing do_signal() to simply restore the saved signal mask in the case where there is no handler to be invoked. The first patch implements the sys_pselect() and sys_ppoll() system calls, which are present only if TIF_RESTORE_SIGMASK is defined. That #ifdef should go away in time when all architectures have implemented it. The second patch implements TIF_RESTORE_SIGMASK for the PowerPC kernel (in the -mm tree), and the third patch then removes the arch-specific implementations of sys_rt_sigsuspend() and replaces them with generic versions using the same trick. The fourth and fifth patches, provided by David Howells, implement TIF_RESTORE_SIGMASK for FR-V and i386 respectively, and the sixth patch adds the syscalls to the i386 syscall table. This patch: Add the pselect() and ppoll() system calls, providing core routines usable by the original select() and poll() system calls and also the new calls (with their semantics w.r.t timeouts).

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.

* | | | | | | [PATCH] knfsd: Provide missing NFSv2 part of patch for checking vfs_getattr.David Shaw2006-01-18

Here is it. This patch moved the call to vfs_getattr from the xdr encoding (at which point it is too late to return an error) to the call handling. This means several calls to vfs_getattr are needed in nfsproc.c. Many are encapsulated in nfsd_return_attrs and nfsd_return_dirop.

Also, nfsd_setattr returns an nfserr which SHOULDN'T be converted from an errno (because it isn't one). Also some tidyups of the form: err = XX err = nfserrno(err) and err = XX if (err) err = nfserrno(err) become err = nfserrno(XX) Signed-off-by: Neil Brown <neilb@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
