smb_receive calls kernel_recvmsg with a size that's the minimum of the amount of buffer space in the kvec passed in or req->rq_rlen (which represents the length of the response). This does not take into account any data that was read in a request earlier pass through smb_receive. If the first pass through smb_receive receives some but not all of the response, then the next pass can call kernel_recvmsg with a size field that's too big. kernel_recvmsg can overrun into the next response, throwing off the alignment and making it unrecognizable. This causes messages like this to pop up in the ring buffer: smb_get_length: Invalid NBT packet, code=69 as well as other errors indicating that the response is unrecognizable. Typically this is seen on a smbfs mount under heavy I/O. This patch changes the code to use (req->rq_rlen - req->rq_bytes_recvd) instead instead of just req->rq_rlen, since that should represent the amount of unread data in the response. I think this is correct, but an ACK or NACK from someone more familiar with this code would be appreciated... Signed-off-by:

- All implementations can be __devinit - The function prototypes were in asm/timex.h but they all must be the same, so create a single declaration in linux/timex.h. - uninline the sparc64 version to match the other architectures - Don't bother #defining ARCH_HAS_READ_CURRENT_TIMER to a particular value.

Some time ago ( http://lkml.org/lkml/2007/6/19/128 ) I wrote about MNT_UNBINDABLE that it felt like a bug that it is not reset by "mount --make-private". Today I happened to see mount(8) and Documentation/sharedsubtree.txt and both document the version obtained by applying the little patch given in the above (and again below). So, the present kernel code is not according to specs and must be regarded as buggy. Specification in Documentation/sharedsubtree.txt: See state diagram: unbindable should become private upon make-private. Specification in mount(8): ... It's also possible to set up uni-directional propagation (with --make- slave), to make a mount point unavailable for --bind/--rbind (with --make-unbindable), and to undo any of these (with --make-private). Repeat of old fix-shared-subtrees-make-private.patch (due to Dirk Gerrits, René Gabriëls, Peter Kooijmans): Acked-by:

This allows a flag to be set on loop devices so that when they are closed for the last time, they'll self-destruct. In general, so that we can automatically allocate loop devices (as with losetup -f) and have them disappear when we're done with them. In particular, right now, so that we can stop relying on the hackish special-case in umount(8) which kills off loop devices which were set up by 'mount -oloop'. That means we can stop putting crap in /etc/mtab which doesn't belong there, which means it can be a symlink to /proc/mounts, which means yet another writable file on the root filesystem is eliminated and the 'stateless' folks get happier... and OLPC trac #356 can be closed. The mount(8) side of that is at http://marc.info/?l=util-linux-ng&m=119362955431694&w=2 [akpm@linux-foundation.org: coding-style fixes] Signed-off-by:

When passing a zero address to kallsyms_lookup(), the kernel thought it was a valid kernel address, even if it is not. This is because is_ksym_addr() called is_kernel_extratext() and checked against labels that don't exist on many archs (which default as zero). Since PPC was the only kernel which defines _extra_text, (in 2005), and no longer needs it, this patch removes _extra_text support.

DMI autoload dcdbas on all Dell systems. This looks for BIOS Vendor or System Vendor == Dell, so this should work for systems both Dell-branded and those Dell builds but brands for others. It causes udev to load the dcdbas module at startup, which is used by tools called by HAL for wireless control and backlight control, among other uses. Thanks to Kay Sievers for figuring out how to do this with a single alias. Signed-off-by:

I would like to potentially move the sparc64 IOMMU code over to using the nice new drivers/pci/iova.[ch] code for free area management.. In order to do that we have to detach the IOMMU page size assumptions which only really need to exist in the intel-iommu.[ch] code. This patch attempts to implement that.

In the new implementation of the [sem|shm|msg]_lock[_check]() routines, we use the return value of ipc_lock() in container_of() without any check. But ipc_lock may return a errcode. The use of this errcode in container_of() may alter this errcode, and we don't want this. And in xxx_exit_ns, the pointer return by idr_find is of type 'struct kern_ipc_per'... Today, the code will work as is because the member used in these container_of() is the first member of its container (offset == 0), the errcode isn't changed then. But in the general case, we can't count on this assumption and this may lead later to a real bug if we don't correct this. Again, the proposed solution is simple and correct. But, as pointed by Nadia, with this solution, the same check will be done several times (in all sub-callers...), what is not very funny/optimal... Signed-off-by:

The 32-bit version is more efficient (and apparently gives better hash results than the 64-bit version), so users who are only hashing a 32-bit quantity can now opt to use the 32-bit version explicitly, rather than promoting to a long. Signed-off-by:

1. It is much easier to grep for ->state change if __set_task_state() is used instead of the direct assignment. 2. ptrace_stop() and handle_group_stop() use set_task_state() which adds the unneeded mb() (btw even if we use mb() it is still possible that do_wait() sees the new ->state but not ->exit_code, but this is ok).

This moves the ability to scale cputime into generic code. This allows us to fix the issue in kernel/timer.c (noticed by Balbir) where we could only add an unscaled value to the scaled utime/stime. This adds a cputime_to_scaled function. As before, the POWERPC version does the scaling based on the last SPURR/PURR ratio calculated. The generic and s390 (only other arch to implement asm/cputime.h) versions are both NOPs. Also moves the SPURR and PURR snapshots closer. Signed-off-by:

After analyzing the elements that save_flags/cli/sti/restore_flags were protecting, convert their usages to a global spinlock (the easiest and most obvious next-step). There were some usages of flags being intentionally cached, because the code already knew the state of interrupts. These have been taken into account. This allows us to remove CONFIG_BROKEN_ON_SMP.

Prohibit mode changes in non-quiet mode that cannot be stored reliably with the on-disk format. Suppose a vfat filesystem is mounted with umask=0 and [not-quiet]. Then all files will have mode 0777. Trying to change the owner will fail, because fat does not know about owners or groups. chmod 0770, on the other hand, will succeed, even though fat does not know about the permission triplet [user/group/other]. So this patch changes fat's not-quiet behavior so that only UNIX modes are accepted that can be mapped lossless between the fat disk format and the local system. There is only one attribute, and that is the readonly attribute, which is mapped to the UNIX write permission bit(s). chmod 0555 is therefore valid (taking away the +w bits <=> setting the readonly attribute). Since chmod 0775 and chmod 0755 is an ambiguous case as to whether to set or clear the readonly bit, these modes are also denied. In quiet mode, chmod and chown will continue to "succeed" as they did before, meaning that a subsequent stat() will temporarily return the new mode as long as the inode is not reread from disk, and chown will silently do nothing, not even return the new uid/gid in stat().
