The generic and IA-64 versions of alloc_zeroed_user_highpage() don't check the return value from alloc_page_vma(). This can lead to an oops if we're OOM. This fixes my oops on PPC64, but I haven't got an IA-64 machine/compiler handy. Signed-off-by:

Close a race which could allow for privilege escalation by users with DRI privileges on Radeon hardware. Essentially, a malicious program could submit a packet containing an offset (possibly in main memory) to be rendered from/to, while a separate thread switched that offset in userspace rapidly between a valid value and an invalid one. radeon_check_and_fixup_offset() would pull the offset in from user space, check it, and spit it back out to user space to be copied in later by the emit code. It would sometimes catch the bad value, but sometimes the malicious program could modify it after the check and get an invalid offset rendered from/to. Fix this by allocating a temporary buffer and copying the data in at once. While here, make the cliprects stuff not do the VERIFYAREA_READ and COPY_FROM_USER_UNCHECKED gymnastics, avoiding a lock order reversal on FreeBSD. Performance impact is negligible -- no difference on r200 to ~1% improvement on rv200 in quake3 tests (P4 1Ghz, demofour at 1024x768, n=4 or 5) From: Eric Anholt <anholt@freebsd.org> Signed-off-by:Dave Airlie <airlied@linux.ie>

The attached patch does two things: (1) We no longer check the return value of file->f_op->get_unmapped_area() unless we actually called it. We know addr is zero otherwise because we'd've given an error earlier if it wasn't. (2) If -ENOSYS was returned by that operation, then we assume we actually called a driver (such as the framebuffer driver) that might want to invoke the operation in a lower level driver (such as matroxfb) if one exists, and that it found that one didn't. We translate the -ENOSYS error into -ENODEV - the error we would have given if the operation was not supplied in the file ops. Doing this permits us an opportunity for arch_get_unmapped_area() or something else to be called if we want that to happen, particularly in the MMU case. Signed-Off-By:

If we detect an overlap, we set a flag and wait for a wakeup. When requests are handled, if the flag was set, we perform the wakeup. Note that the code currently in -mm is badly broken. With this patch applied, it passes tests the use O_DIRECT to cause lots of overlapping requests. Signed-off-by:

We presently deadlock in low-latency mode because the receive code holds port.lock while calling into the tty code to perform echoing. The tty code calls back into the driver, which then takes port.lock. Fix that by dropping the lock around the echo call. Acked-by:

Frank Fricke reported that hostfs does not verify that a chmod +s, for instance, is done by a sufficiently privileged user, as long as the UML kernel itself can complete the operation on the host. So, for instance, if UML is run as root and under /mnt/host we have a hostfs mount, this works successfully: paolo@zion:~ (0)$ chmod 4755 /mnt/host/bin/bash paolo@zion:~ (0)$ ll /mnt/host/bin/bash -rwsr-xr-x 1 root root 662724 2004-10-20 02:15 /mnt/host/bin/bash* (bash refuses running as setuid, but you could have another shell on the host, as dash or whatever). In general, if UML is run as uid 500 on the host, a hostfs mount is done and under the hostfs mount there is a file with uid 500 on the host, I can freely make it setuid (if it's executable). This is especially bad when UML is run as root (which you should not do), but is a problem in general, since it allows any user to create setuid 500 (in this example) executables on the host filesystem. Finally, while I was looking at the chmod() implementation, I spotted a kludge in the code and explained it with a comment. Signed-off-by:

When a task is put to sleep, it is dequeued from the runqueue while it is still running. The problem is that one some arches that have non-atomic scheduling, the runqueue lock can be dropped and retaken in schedule() before the task actually schedules off, and wait_task_inactive did not account for this.
