* ns: Wire up the setns system callEric W. Biederman2011-05-281-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 32bit and 64bit on x86 are tested and working. The rest I have looked at closely and I can't find any problems. setns is an easy system call to wire up. It just takes two ints so I don't expect any weird architecture porting problems. While doing this I have noticed that we have some architectures that are very slow to get new system calls. cris seems to be the slowest where the last system calls wired up were preadv and pwritev. avr32 is weird in that recvmmsg was wired up but never declared in unistd.h. frv is behind with perf_event_open being the last syscall wired up. On h8300 the last system call wired up was epoll_wait. On m32r the last system call wired up was fallocate. mn10300 has recvmmsg as the last system call wired up. The rest seem to at least have syncfs wired up which was new in the 2.6.39. v2: Most of the architecture support added by Daniel Lezcano <dlezcano@fr.ibm.com> v3: ported to v2.6.36-rc4 by: Eric W. Biederman <ebiederm@xmission.com> v4: Moved wiring up of the system call to another patch v5: ported to v2.6.39-rc6 v6: rebased onto parisc-next and net-next to avoid syscall conflicts. v7: ported to Linus's latest post 2.6.39 tree. >  arch/blackfin/include/asm/unistd.h     |    3 ++- >  arch/blackfin/mach-common/entry.S      |    1 + Acked-by: Mike Frysinger <vapier@gentoo.org> Oh - ia64 wiring looks good.

| * microblaze: Fix /dev/zero corruption from __clear_user()Steven J. Magnani2011-03-091-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A userland read of more than PAGE_SIZE bytes from /dev/zero results in (a) not all of the bytes returned being zero, and (b) memory corruption due to zeroing of bytes beyond the user buffer. This is caused by improper constraints on the assembly __clear_user function. The constrints don't indicate to the compiler that the pointer argument is modified. Since the function is inline, this results in double-incrementing of the pointer when __clear_user() is invoked through a multi-page read() of /dev/zero. Signed-off-by: Steven J.

This was confusing at best, and could be a source of livelocks in places that retry the cmpxchg_futex_value_locked after trying to fix the issue by running fault_in_user_writeable(). This change makes the cmpxchg_futex_value_locked API more similar to the get_futex_value_locked one, returning an error code and updating the original value through a reference argument.
