Move the i386 VDSO down into a vma and thus randomize it. Besides the security implications, this feature also helps debuggers, which can COW a vma-backed VDSO just like a normal DSO and can thus do single-stepping and other debugging features. It's good for hypervisors (Xen, VMWare) too, which typically live in the same high-mapped address space as the VDSO, hence whenever the VDSO is used, they get lots of guest pagefaults and have to fix such guest accesses up - which slows things down instead of speeding things up (the primary purpose of the VDSO). There's a new CONFIG_COMPAT_VDSO (default=y) option, which provides support for older glibcs that still rely on a prelinked high-mapped VDSO. Newer distributions (using glibc 2.3.3 or later) can turn this option off. Turning it off is also recommended for security reasons: attackers cannot use the predictable high-mapped VDSO page as syscall trampoline anymore. There is a new vdso=[0|1] boot option as well, and a runtime /proc/sys/vm/vdso_enabled sysctl switch, that allows the VDSO to be turned on/off. (This version of the VDSO-randomization patch also has working ELF coredumping, the previous patch crashed in the coredumping code.) This code is a combined work of the exec-shield VDSO randomization code and Gerd Hoffmann's hypervisor-centric VDSO patch. Rusty Russell started this patch and i completed it.

Commit c3ff8ec3 ("[PATCH] i386: Don't miss pending signals returning to user mode after signal processing") meant that vm86 interrupt/signal handling got broken for the case when vm86 is called from kernel space. In this scenario, if signal is pending because of vm86 interrupt, do_notify_resume/do_signal exits immediately due to user_mode() check, without processing any signals. Thus, resume_userspace handler is spinning in a tight loop with signal pending and TIF_SIGPENDING is set. Previously everything worked Ok. No in-tree usage of vm86() from kernel space exists, but I've heard about a number of projects out there which use vm86 calls from kernel, one of them being this, for instance: http://dev.gentoo.org/~spock/projects/vesafb-tng/ The following patch fixes the issue.

Remove the limit of 256 interrupt vectors by changing the value stored in orig_{e,r}ax to be the complemented interrupt vector. The orig_{e,r}ax needs to be < 0 to allow the signal code to distinguish between return from interrupt and return from syscall. With this change applied, NR_IRQS can be > 256. Xen extends the IRQ numbering space to include room for dynamically allocated virtual interrupts (in the range 256-511), which requires a more permissive interface to do_IRQ.

由 KAMEZAWA Hiroyuki 提交于
With Goto-san's patch, we can add new pgdat/node at runtime. I'm now considering node-hot-add with cpu + memory on ACPI. I found acpi container, which describes node, could evaluate cpu before memory. This means cpu-hot-add occurs before memory hot add. In most part, cpu-hot-add doesn't depend on node hot add. But register_cpu(), which creates symbolic link from node to cpu, requires that node should be onlined before register_cpu(). When a node is onlined, its pgdat should be there. This patch-set holds off creating symbolic link from node to cpu until node is onlined. This removes node arguments from register_cpu(). Now, register_cpu() requires 'struct node' as its argument. But the array of struct node is now unified in driver/base/node.c now (By Goto's node hotplug patch). We can get struct node in generic way. So, this argument is not necessary now. This patch also guarantees add cpu under node only when node is onlined. It is necessary for node-hot-add vs. cpu-hot-add patch following this. Moreover, register_cpu calculates cpu->node_id by cpu_to_node() without regard to its 'struct node *root' argument. This patch removes it. Also modify callers of register_cpu()/unregister_cpu, whose args are changed by register-cpu-remove-node-struct patch.

This is to refresh node_data[] array for ia64. As I mentioned previous patches, ia64 has copies of information of pgdat address array on each node as per node data. At v2 of node_add, this function used stop_machine_run() to update them. (I wished that they were copied safety as much as possible.) But, in this patch, this arrays are just copied simply, and set node_online_map bit after completion of pgdat initialization. So, kernel must touch NODE_DATA() macro after checking node_online_map(). (Current code has already done it.) This is more simple way for just hot-add..... Note : It will be problem when hot-remove will occur, because, even if online_map bit is set, kernel may touch NODE_DATA() due to race condition. :-( Signed-off-by: NYasunori Goto <y-goto@jp.fujitsu.com> Cc: "Luck, Tony" <tony.luck@intel.com> Signed-off-by: NAndrew Morton <akpm@osdl.org> Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

When new node becomes enable by hot-add, new sysfs file must be created for new node. So, if new node is enabled by add_memory(), register_one_node() is called to create it.

This patch allows hot-add memory which is not aligned to section. Now, hot-added memory has to be aligned to section size. Considering big section sized archs, this is not useful. When hot-added memory is registerd as iomem resoruce by iomem resource patch, we can make use of that information to detect valid memory range. Note: With this, not-aligned memory can be registerd. To allow hot-add memory with holes, we have to do more work around add_memory(). (It doesn't allows add memory to already existing mem section.)

Add node-hot-add support to add_memory(). node hotadd uses this sequence. 1. allocate pgdat. 2. refresh NODE_DATA() 3. call free_area_init_node() to initialize 4. create sysfs entry 5. add memory (old add_memory()) 6. set node online 7. run kswapd for new node. (8). update zonelist after pages are onlined. (This is already merged in -mm due to update phase is difference.) Note: To make common function as much as possible, there is 2 changes from v2. - The old add_memory(), which is defiend by each archs, is renamed to arch_add_memory(). New add_memory becomes caller of arch dependent function as a common code. - This patch changes add_memory()'s interface From: add_memory(start, end) TO : add_memory(nid, start, end). It was cause of similar code that finding node id from physical address is inside of old add_memory() on each arch. In addition, acpi memory hotplug driver can find node id easier. In v2, it must walk DSDT'S _CRS by matching physical address to get the handle of its memory device, then get _PXM and node id. Because input is just physical address. However, in v3, the acpi driver can use handle to get _PXM and node id for the new memory device. It can pass just node id to add_memory(). Fix interface of arch_add_memory() is in next patche.

For node hotplug, basically we have to allocate new pgdat. But, there are several types of implementations of pgdat. 1. Allocate only pgdat. This style allocate only pgdat area. And its address is recorded in node_data[]. It is most popular style. 2. Static array of pgdat In this case, all of pgdats are static array. Some archs use this style. 3. Allocate not only pgdat, but also per node data. To increase performance, each node has copy of some data as a per node data. So, this area must be allocated too. Ia64 is this style. Ia64 has the copies of node_data[] array on each per node data to increase performance. In this series of patches, treat (1) as generic arch. generic archs can use generic function. (2) and (3) should have its own if necessary. This patch defines pgdat allocator. Updating NODE_DATA() macro function is in other patch.

Container device driver calls acpi_bus_scan() to find and add belonging devices (which means cpu, memory and so on). Its function calls add and start function of belonging devices's driver. Howevever, current memory hotplug driver just register add function to create sysfs file for its memory. But, acpi_memory_enable_device() is not called because it is considered just the case that notify reaches memory device directly. So, if notify reaches container device nothing can call add_memory().

Tested on ia64 memory hotplug test envrionment (not emulation, uses alpha version firmware which supports dynamic reconfiguration of NUMA.) Note: Microsoft's Windows Server 2003 requires big (>4G)resoureces to be divided into small (<4G) resources. looks crazy, but not invalid. (See http://www.microsoft.com/whdc/system/pnppwr/hotadd/hotaddmem.mspx) For this reason, a firmware vendor who supports Windows writes plural resources in a _CRS even if they are contiguous.

This reverts commit e5c44fd8. Thanks to Daniel Ritz and Michal Piotrowski for noticing the problem. Daniel says: "[The] reason is a recent change that made modules always shows as module.mod. it breaks modprobe and probably many scripts..besides lsmod looking horrible stuff like this in modprobe.conf: install pcmcia_core /sbin/modprobe --ignore-install pcmcia_core; /sbin/modprobe pcmcia makes modprobe fork/exec endlessly calling itself...until oom interrupts it" Signed-off-by: NLinus Torvalds <torvalds@osdl.org>
