2009-10-09Staging: comedi: fix build on arches that don't want comedi driversGreg Kroah-Hartman
This should fix the problem of comedi drivers showing up on arches that can not support the comedi subsystem (like s390).

2009-10-09Staging: p9auth: a few fixesSerge E. Hallyn
1. The memory into which we copy 'u1@u2' needs space for u1, @, u2, and a final \0 which strcat copies in. 2. Strsep changes the value of its first argument. So use a temporary variable to pass to it, so we pass the original value to kfree! 3. Allocate an extra char to user_buf, because we need a trailing \0 since we later kstrdup it. I am about to send out an LTP testcase for this driver, but in addition the correctness of the hashing can be verified as follows: #include <stdio.h> #include <stdlib.h> #include <unistd.h> int main(int argc, char *argv[]) { char in[41], out[20]; unsigned int v; int i, ret; ret = read(STDIN_FILENO, in, 40); if (ret != 40) exit(1); in[40] = '\0'; for (i = 0; i < 20; i++) { sscanf(&in[2*i], "%02x", &v); out[i] = v; } write(STDOUT_FILENO, out, 20); } as root, to test userid 501 switching to uid 0, choosing 'random' string 'ab': echo -n "501@0" > plain openssl sha1 -hmac 'ab' plain |awk '{ print $2 '} > dgst ./unhex < dgst > dgst.u mknod /dev/caphash 504 0 mknod /dev/capuse 504 1 chmod ugo+w /dev/capuse cat dgst.u > /dev/caphash as uid 501, echo "501@0@ab" > /dev/capuse id -u # should now show 0.

2009-10-08x86, timers: Check for pending timers after (device) interruptsArjan van de Ven
Now that range timers and deferred timers are common, I found a problem with these using the "perf timechart" tool. Frans Pop also reported high scheduler latencies via LatencyTop, when using iwlagn. It turns out that on x86, these two 'opportunistic' timers only get checked when another "real" timer happens. These opportunistic timers have the objective to save power by hitchhiking on other wakeups, as to avoid CPU wakeups by themselves as much as possible. The change in this patch runs this check not only at timer interrupts, but at all (device) interrupts. The effect is that: 1) the deferred timers/range timers get delayed less 2) the range timers cause less wakeups by themselves because the percentage of hitchhiking on existing wakeup events goes up. I've verified the working of the patch using "perf timechart", the original exposed bug is gone with this patch. Frans also reported success - the latencies are now down in the expected ~10 msec range.

2009-10-08mm, perf_event: Make vmalloc_user() align base kernel virtual address to SHMLBADavid Miller
When a vmalloc'd area is mmap'd into userspace, some kind of co-ordination is necessary for this to work on platforms with cpu D-caches which can have aliases. Otherwise kernel side writes won't be seen properly in userspace and vice versa. If the kernel side mapping and the user side one have the same alignment, modulo SHMLBA, this can work as long as VM_SHARED is shared of VMA and for all current users this is true. VM_SHARED will force SHMLBA alignment of the user side mmap on platforms with D-cache aliasing matters. The bulk of this patch is just making it so that a specific alignment can be passed down into __get_vm_area_node(). All existing callers pass in '1' which preserves existing behavior. vmalloc_user() gives SHMLBA for the alignment. As a side effect this should get the video media drivers and other vmalloc_user() users into more working shape on such systems. Signed-off-by: David S.

2009-10-08cgroups: update documentation of cgroups tasks and procs filesPaul Menage
Update documentation of cgroups tasks and procs files Document the cgroup.procs file. Clarify the semantics of the cgroup.procs and tasks files. Although the current cgroup.procs interface returns a sorted and uniqified list of pids, potential future performance enhancements could result in those properties being removed - explicitly document this aspect of the API. There are no existing users of cgroup.procs, so compatibility isn't an issue. There are users of the "tasks" file, but none that would appear to break in the event of the sorted property being broken. The standard "libcpuset" explicitly sorts the results of reading from the tasks file, and "libcg" and other users don't appear to care about ordering.
