fuse: llseek fix race

2011-12-13T10:40:59Z

Fix race between lseek(fd, 0, SEEK_CUR) and read/write. This was fixed in generic code by commit 5b6f1eb97d (vfs: lseek(fd, 0, SEEK_CUR) race condition). Signed-off-by: Miklos Szeredi

fuse: fix llseek bug

2011-12-13T09:37:00Z

The test in fuse_file_llseek() "not SEEK_CUR or not SEEK_SET" always evaluates to true. This was introduced in 3.1 by commit 06222e49 (fs: handle SEEK_HOLE/SEEK_DATA properly in all fs's that define their own llseek) and changed the behavior of SEEK_CUR and SEEK_SET to always retrieve the file attributes. This is a performance regression. Fix the test so that it makes sense. Signed-off-by: Miklos Szeredi CC: stable@vger.kernel.org CC: Josef Bacik CC: Al Viro

fuse: fix fuse_retrieve

2011-12-13T09:36:59Z

Fix two bugs in fuse_retrieve(): - retrieving more than one page would yield repeated instances of the first page - if more than FUSE_MAX_PAGES_PER_REQ pages were requested than the request page array would overflow fuse_retrieve() was added in 2.6.36 and these bugs had been there since the beginning.

fs: add module.h to files that were implicitly using it

2011-10-31T23:30:31Z

Some files were using the complete module.h infrastructure without actually including the header at all. Fix them up in advance so once the implicit presence is removed, we won't get failures like this: CC [M] fs/nfsd/nfssvc.o fs/nfsd/nfssvc.c: In function 'nfsd_create_serv': fs/nfsd/nfssvc.c:335: error: 'THIS_MODULE' undeclared (first use in this function) fs/nfsd/nfssvc.c:335: error: (Each undeclared identifier is reported only once fs/nfsd/nfssvc.c:335: error: for each function it appears in.) fs/nfsd/nfssvc.c: In function 'nfsd': fs/nfsd/nfssvc.c:555: error: implicit declaration of function 'module_put_and_exit' make[3]: *** [fs/nfsd/nfssvc.o] Error 1 Signed-off-by: Paul Gortmaker

fuse: fix flock breakage

2011-09-12T18:47:10Z

Commit 37fb3a30b4 ("fuse: fix flock") added in 3.1-rc4 caused flock() to fail with ENOSYS with the kernel ABI version 7.16 or earlier. Fix by falling back to testing FUSE_POSIX_LOCKS for ABI versions 7.16 and earlier. Reported-by: Martin Ziegler Signed-off-by: Miklos Szeredi Tested-by: Martin Ziegler Signed-off-by: Linus Torvalds
