Wrong error path in dup_fd() - it should return NULL on error, not an address of already freed memory :/ Triggered by OpenVZ stress test suite.

This patch replaces the split ISO raw_mask calculation code in the iso_stream_init() function that computed incorrect numbers of high speed transactions for both input and output transfers. In the output case, it added a superfluous start-split transaction for all maxmimum packet sizes that are a multiple of 188. In the input case, it forgot to add complete-split transactions for all microframes covered by the full speed transaction, and the additional complete-split transaction needed for the case when full speed data starts arriving near the end of a microframe. These changes don't affect the lack of full speed bandwidth, but at least it removes the MMF errors that the HC raised with some input streams. Signed-off-by:

tlclk calls register_chrdev() and permits register_chrdev() to allocate the major, but it promptly forgets what that major was. So if there's no hardware present you still get "telco_clock" appearing in /proc/devices and, I assume, an oops reading /proc/devices if tlclk was a module. Fix. Mark, I'd suggest that that we not call register_chrdev() until _after_ we've established that the hardware is present. Cc: Mark Gross <mgross@linux.intel.com> Signed-off-by:

We have noticed lockups during boot when stress testing kexec on ppc64. Two cpus would deadlock in scheduler code trying to grab already taken spinlocks. The double_rq_lock code uses the address of the runqueue to order the taking of multiple locks. This address is a per cpu variable: if (rq1 < rq2) { spin_lock(&rq1->lock); spin_lock(&rq2->lock); } else { spin_lock(&rq2->lock); spin_lock(&rq1->lock); } On the other hand, the code in wake_sleeping_dependent uses the cpu id order to grab locks: for_each_cpu_mask(i, sibling_map) spin_lock(&cpu_rq(i)->lock); This means we rely on the address of per cpu data increasing as cpu ids increase. While this will be true for the generic percpu implementation it may not be true for arch specific implementations. One way to solve this is to always take runqueues in cpu id order. To do this we add a cpu variable to the runqueue and check it in the double runqueue locking functions. Signed-off-by:Anton Blanchard <anton@samba.org> Acked-by:

If a file is not found in v9fs_vfs_lookup, the function creates negative dentry, but doesn't assign any dentry ops. This leaves the negative entry in the cache (there is no d_delete to mark it for removal). If the file is created outside of the mounted v9fs filesystem, the file shows up in the directory with weird permissions. This patch assigns the default v9fs dentry ops to the negative dentry.

The fw_realloc_buffer routine does not handle an increase in buffer size of more than 4k. It's not clear to me why it expects that it will only get an extra 4k of data. The attached patch modifies fw_realloc_buffer to vmalloc as much memory as is requested, instead of what we previously had + 4k. I've tested this on my laptop, which would crash occaisionally on boot without the patch. With the patch, it hasn't crashed, but I can't be certain that this code path is exercised. Signed-off-by:

The problem is in ip_push_pending_frames(), which uses: if (!df) { __ip_select_ident(iph, &rt->u.dst, 0); } else { iph->id = htons(inet->id++); } instead of ip_select_ident(). Right now I think the code is a nonsense. Most likely, I copied it from old ip_build_xmit(), where it was really special, we had to decide whether to generate unique ID when generating the first (well, the last) fragment. In ip_push_pending_frames() it does not make sense, it should use plain ip_select_ident() instead. Signed-off-by:Alexey Kuznetsov <kuznet@ms2.inr.ac.ru> Signed-off-by:
