* xtime_lock vs update_process_timesPeter Zijlstra2008-02-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit d3d74453c34f8fd87674a8cf5b8a327c68f22e99 ("hrtimer: fixup the HRTIMER_CB_IRQSAFE_NO_SOFTIRQ fallback") broke several archs, and since only Russell bothered to merge the fix, and Greg to ACK his arch, I'm sending this for merger. I have confirmation that the Alpha bit results in a booting kernel. That leaves: blackfin, frv, sh and sparc untested. The deadlock in question was found by Russell: IRQ handle -> timer_tick() - xtime seqlock held for write -> update_process_times() -> run_local_timers() -> hrtimer_run_queues() -> hrtimer_get_softirq_time() - tries to get a read lock Now, Thomas assures me the fix is trivial, only do_timer() needs to be done under the xtime_lock, and update_process_times() can savely be removed from under it.

* acpi: fix acpi_os_read_pci_configuration() misuse of raw_pci_read()Linus Torvalds2008-02-13
| | | | | | | | | | | | | | | The raw_pci_read() interface (as the raw_pci_ops->read() before it) unconditionally fills in a 32-bit integer return value regardless of the size of the operation requested. So claiming to take a "void *" is wrong, as is passing in a pointer to just a byte variable. Noticed by pageexec when enabling -fstack-protector (which needs other patches too to actually work, but that's a separate issue).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Steven mentioned the fun case where a lock holding task will be throttled. Simple fix: allow groups that have boosted tasks to run anyway. If a runnable task in a throttled group gets boosted the dequeue/enqueue done by rt_mutex_setprio() is enough to unthrottle the group. This is ofcourse not quite correct.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch enhances EFI runtime code memory mapping as following: - Move __supported_pte_mask & _PAGE_NX checking before invoking runtime_code_page_mkexec(). This makes it possible for compiler to eliminate runtime_code_page_mkexec() on machine without NX support. - Use set_memory_x/nx in early_mapping_set_exec().

* mempolicy: silently restrict nodemask to allowed nodesKOSAKI Motohiro2008-02-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Kosaki Motohito noted that "numactl --interleave=all ..." failed in the presence of memoryless nodes. This patch attempts to fix that problem. Some background: numactl --interleave=all calls set_mempolicy(2) with a fully populated [out to MAXNUMNODES] nodemask. set_mempolicy() [in do_set_mempolicy()] calls contextualize_policy() which requires that the nodemask be a subset of the current task's mems_allowed; else EINVAL will be returned. A task's mems_allowed will always be a subset of node_states[N_HIGH_MEMORY] i.e., nodes with memory. So, a fully populated nodemask will be declared invalid if it includes memoryless nodes. NOTE: the same thing will occur when running in a cpuset with restricted mem_allowed--for the same reason: node mask contains dis-allowed nodes. mbind(2), on the other hand, just masks off any nodes in the nodemask that are not included in the caller's mems_allowed. In each case [mbind() and set_mempolicy()], mpol_check_policy() will complain [again, resulting in EINVAL] if the nodemask contains any memoryless nodes. This is somewhat redundant as mpol_new() will remove memoryless nodes for interleave policy, as will bind_zonelist()--called by mpol_new() for BIND policy. Proposed fix: 1) modify contextualize_policy logic to: a) remember whether the incoming node mask is empty. b) if not, restrict the nodemask to allowed nodes, as is currently done in-line for mbind(). This guarantees that the resulting mask includes only nodes with memory. NOTE: this is a [benign, IMO] change in behavior for set_mempolicy(). Dis-allowed nodes will be silently ignored, rather than returning an error. c) fold this code into mpol_check_policy(), replace 2 calls to contextualize_policy() to call mpol_check_policy() directly and remove contextualize_policy(). 2) In existing mpol_check_policy() logic, after "contextualization": a) MPOL_DEFAULT: require that in coming mask "was_empty" b) MPOL_{BIND|INTERLEAVE}: require that contextualized nodemask contains at least one node. c) add a case for MPOL_PREFERRED: if in coming was not empty and resulting mask IS empty, user specified invalid nodes. Return EINVAL. c) remove the now redundant check for memoryless nodes 3) remove the now redundant masking of policy nodes for interleave policy from mpol_new(). 4) Now that mpol_check_policy() contextualizes the nodemask, remove the in-line nodes_and() from sys_mbind(). I believe that this restores mbind() to the behavior before the memoryless-nodes patch series. E.g., we'll no longer treat an invalid nodemask with MPOL_PREFERRED as local allocation. [ Patch history: v1 -> v2: - Communicate whether or not incoming node mask was empty to mpol_check_policy() for better error checking. - As suggested by David Rientjes, remove the now unused cpuset_nodes_subset_current_mems_allowed() from cpuset.h v2 -> v3: - As suggested by Kosaki Motohito, fold the "contextualization" of policy nodemask into mpol_check_policy().

* | Be more robust about bad arguments in get_user_pages()Jonathan Corbet2008-02-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So I spent a while pounding my head against my monitor trying to figure out the vmsplice() vulnerability - how could a failure to check for *read* access turn into a root exploit? It turns out that it's a buffer overflow problem which is made easy by the way get_user_pages() is coded. In particular, "len" is a signed int, and it is only checked at the *end* of a do {} while() loop. So, if it is passed in as zero, the loop will execute once and decrement len to -1. At that point, the loop will proceed until the next invalid address is found; in the process, it will likely overflow the pages array passed in to get_user_pages(). I think that, if get_user_pages() has been asked to grab zero pages, that's what it should do. Thus this patch; it is, among other things, enough to block the (already fixed) root exploit and any others which might be lurking in similar code. I also think that the number of pages should be unsigned, but changing the prototype of this function probably requires some more careful review.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some controllers (VIA CX700) raise device error on SETXFER even after mode configuration succeeded. Update ata_dev_set_mode() such that device error is ignored if transfer mode is configured correctly. To implement this, device is revalidated even after device error on SETXFER. This fixes kernel bugzilla bug 8563. Signed-off-by: Tejun Heo <htejun@gmail.com> Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Signed-off-by: Jeff Garzik <jeff@garzik.org>
