2011-08-26T22:09:58Z

The nfsservctl system call is now gone, so we should remove all linkage for it. Signed-off-by: NeilBrown Signed-off-by: J. Bruce Fields Signed-off-by: Linus Torvalds

nfsd: Remove deprecated nfsctl system call and related code.

2011-07-15T22:58:42Z

As promised in feature-removal-schedule.txt it is time to remove the nfsctl system call. Userspace has perferred to not use this call throughout 2.6 and it has been excluded in the default configuration since 2.6.36 (9 months ago). So this patch removes all the code that was being compiled out. There are still references to sys_nfsctl in various arch systemcall tables and related code. These should be cleaned out too, probably in the next merge window. Signed-off-by: NeilBrown Signed-off-by: J. Bruce Fields

exec: unify do_execve/compat_do_execve code

2011-04-09T13:53:56Z

Add the appropriate members into struct user_arg_ptr and teach get_user_arg_ptr() to handle is_compat = T case correctly. This allows us to remove the compat_do_execve() code from fs/compat.c and reimplement compat_do_execve() as the trivial wrapper on top of do_execve_common(is_compat => true). In fact, this fixes another (minor) bug. "compat_uptr_t str" can overflow after "str += len" in compat_copy_strings() if a 64bit application execs via sys32_execve(). Unexport acct_arg_size() and get_arg_page(), fs/compat.c doesn't need them any longer. Signed-off-by: Oleg Nesterov Reviewed-by: KOSAKI Motohiro Tested-by: KOSAKI Motohiro

clean statfs-like syscalls up

2011-03-14T13:15:28Z

New helpers: user_statfs() and fd_statfs(), taking userland pathname and descriptor resp. and filling struct kstatfs. Syscalls of statfs family (native, compat and foreign - osf and hpux on alpha and parisc resp.) switched to those. Removes some boilerplate code, simplifies cleanup on errors...

compat breakage in preadv() and pwritev()

2011-03-13T23:21:26Z

Fix for a dumb preadv()/pwritev() compat bug - unlike the native variants, compat_... ones forget to check FMODE_P{READ,WRITE}, so e.g. on pipe the native preadv() will fail with -ESPIPE and compat one will act as readv() and succeed. Not critical, but it's a clear bug with trivial fix. Signed-off-by: Al Viro

compat: copy missing fields in compat_statfs64 to user

compat: update comment of compat statfs syscalls

2011-01-17T09:54:38Z

The commit 7ed1ee6118ae ("Take statfs variants to fs/statfs.c") separates out statfs syscalls from fs/open.c. Thus the comment should be changed also. Signed-off-by: Namhyung Kim Cc: Jiri Kosina Signed-off-by: Al Viro

compat: remove unnecessary assignment in compat_rw_copy_check_uvector()

*@ret_pointer is initialized to @fast_pointer thus the assignment is redundant. Signed-off-by: Namhyung Kim Cc: Jeff Moyer Signed-off-by: Al Viro
