2013-10-14Revert "of: Feed entire flattened device tree into the random pool"Grant Likely1-12/+0
This reverts commit 109b6236294b53d8eaa50be7d9e9ad37079f5f7e. Tim Bird expressed concern that this will have a bad effect on boot time, and while simple tests have shown it to be okay with simple tree, a device tree blob can potentially be quite large and add_device_randomness() is not a fast function. Rather than do this for all platforms unconditionally, I'm reverting this patch and would like to see it revisited. Instead of feeding the entire tree into the random pool, it would probably be appropriate to hash the tree and feed the hash result into the pool. There really isn't a lot of randomness in a device tree anyway. In the majority of cases only a handful of properties are going to be different between machines with the same baseboard.

2013-10-14of: fix unnecessary warning on missing /cpus nodeGrant Likely1-3/+1
Not all DT platforms have all the cpus collected under a /cpus node. That just happens to be a details of FDT, ePAPR and PowerPC platforms. Sparc does something different, but unfortunately the current code complains with a warning if /cpus isn't there. This became a problem with commit f86e4718, "driver/core cpu: initialize of_node in cpu's device structure", which caused the function to get called for all architectures. This commit is a temporary fix to fail silently if the cpus node isn't present. A proper fix will come later to allow arch code to provide a custom mechanism for decoding the CPU hwid if the 'reg' property isn't appropriate.

2013-10-14ALSA: hda - Fix inverted internal mic not indicated on some machinesDavid Henningsson1-1/+1
The create_bind_cap_vol_ctl does not create any control indicating that an inverted dmic is present. Therefore, create multiple capture volumes in this scenario, so we always have some indication that the internal mic is inverted. This happens on the Lenovo Ideapad U310 as well as the Lenovo Yoga 13 (both are based on the CX20590 codec), but the fix is generic and could be needed for other codecs/machines too. Thanks to Szymon Acedański for the pointer and a draft patch.

2013-10-14wireless: radiotap: fix parsing buffer overrunJohannes Berg1-1/+6
When parsing an invalid radiotap header, the parser can overrun the buffer that is passed in because it doesn't correctly check 1) the minimum radiotap header size 2) the space for extended bitmaps The first issue doesn't affect any in-kernel user as they all check the minimum size before calling the radiotap function. The second issue could potentially affect the kernel if an skb is passed in that consists only of the radiotap header with a lot of extended bitmaps that extend past the SKB. In that case a read-only buffer overrun by at most 4 bytes is possible. Fix this by adding the appropriate checks to the parser.

2013-10-13cgroup: fix to break the while loop in cgroup_attach_task() correctlyAnjana V Kumar1-3/+3
Both Anjana and Eunki reported a stall in the while_each_thread loop in cgroup_attach_task(). It's because, when we attach a single thread to a cgroup, if the cgroup is exiting or is already in that cgroup, we won't break the loop. If the task is already in the cgroup, the bug can lead to another thread being attached to the cgroup unexpectedly: # echo 5207 > tasks # cat tasks 5207 # echo 5207 > tasks # cat tasks 5207 5215 What's worse, if the task to be attached isn't the leader of the thread group, we might never exit the loop, hence cpu stall. Thanks for Oleg's analysis. This bug was introduced by commit 081aa458c38ba576bdd4265fc807fa95b48b9e79 ("cgroup: consolidate cgroup_attach_task() and cgroup_attach_proc()") [ lizf: - fixed the first continue, pointed out by Oleg, - rewrote changelog. ] Cc: <[email protected]> # 3.9+ Reported-by: Eunki Kim <[email protected]> Reported-by: Anjana V Kumar <[email protected]> Signed-off-by: Anjana V Kumar <[email protected]> Signed-off-by: Li Zefan <[email protected]> Signed-off-by: Tejun Heo <[email protected]>

2013-10-13ARM: 7851/1: check for number of arguments in syscall_get/set_arguments()AKASHI Takahiro1-0/+6
In ftrace_syscall_enter(), syscall_get_arguments(..., 0, n, ...) if (i == 0) { <handle ORIG_r0> ...; n--;} memcpy(..., n * sizeof(args[0])); If 'number of arguments(n)' is zero and 'argument index(i)' is also zero in syscall_get_arguments(), none of arguments should be copied by memcpy(). Otherwise 'n--' can be a big positive number and unexpected amount of data will be copied. Tracing system calls which take no argument, say sync(void), may hit this case and eventually make the system corrupted. This patch fixes the issue both in syscall_get_arguments() and syscall_set_arguments().

2013-10-13parisc: fix interruption handler to respect pagefault_disable()Helge Deller1-3/+3
Running an "echo t > /proc/sysrq-trigger" crashes the parisc kernel. The problem is, that in print_worker_info() we try to read the workqueue info via the probe_kernel_read() functions which use pagefault_disable() to avoid crashes like this: probe_kernel_read(&pwq, &worker->current_pwq, sizeof(pwq)); probe_kernel_read(&wq, &pwq->wq, sizeof(wq)); probe_kernel_read(name, wq->name, sizeof(name) - 1); The problem here is, that the first probe_kernel_read(&pwq) might return zero in pwq and as such the following probe_kernel_reads() try to access contents of the page zero which is read protected and generate a kernel segfault. With this patch we fix the interruption handler to call parisc_terminate() directly only if pagefault_disable() was not called (in which case preempt_count()==0). Otherwise we hand over to the pagefault handler which will try to look up the faulting address in the fixup tables.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull gcc "asm goto" miscompilation workaround from Ingo Molnar: "This is the fix for the GCC miscompilation discussed in the following lkml thread: [x86] BUG: unable to handle kernel paging request at 00740060 The bug in GCC has been fixed by Jakub and the fix will be part of the GCC 4.8.2 release expected to be released next week - so the quirk's version test checks for <= 4.8.1. The quirk is only added to compiler-gcc4.h and not to the higher level compiler.h because all asm goto uses are behind a feature check" * 'core-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: compiler/gcc4: Add quirk for 'asm goto' miscompilation bug

2013-10-12ARC: Ignore ptrace SETREGSET request for synthetic register "stop_pc"Vineet Gupta1-1/+1
ARCompact TRAP_S insn used for breakpoints, commits before exception is taken (updating architectural PC). So ptregs->ret contains next-PC and not the breakpoint PC itself. This is different from other restartable exceptions such as TLB Miss where ptregs->ret has exact faulting PC. gdb needs to know exact-PC hence ARC ptrace GETREGSET provides for @stop_pc which returns ptregs->ret vs. EFA depending on the situation. However, writing stop_pc (SETREGSET request), which updates ptregs->ret doesn't makes sense stop_pc doesn't always correspond to that reg as described above. This was not an issue so far since user_regs->ret / user_regs->stop_pc had same value and both writing to ptregs->ret was OK, needless, but NOT broken, hence not observed. With gdb "jump", they diverge, and user_regs->ret updating ptregs is overwritten immediately with stop_pc, which this patch fixes.

The WARN_ON() in acpiphp_enumerate_slots() triggers unnecessarily for devices whose bridges are going to be handled by native PCIe hotplug (pciehp) and the simplest way to prevent that from happening is to drop the WARN_ON().
