| 5e391dc | David Gibson | 23 November 2005, 21:37:45 UTC | [PATCH] powerpc: fix for hugepage areas straddling 4GB boundary Commit 7d24f0b8a53261709938ffabe3e00f88f6498df9 fixed bugs in the ppc64 SLB miss handler with respect to hugepage handling, and in the process tweaked the semantics of the hugepage address masks in mm_context_t. Unfortunately, it left out a couple of necessary changes to go with that change. First, the in_hugepage_area() macro was not updated to match, second prepare_hugepage_range() was not updated to correctly handle hugepages regions which straddled the 4GB point. The latter appears only to cause process-hangs when attempting to map such a region, but the former can cause oopses if a get_user_pages() is triggered at the wrong point. This patch addresses both bugs.

| 8bf1101 | Jim Keniston | 23 November 2005, 21:37:42 UTC | [PATCH] kprobes: Fix return probes on sys_execve Fix a bug in kprobes that can cause an Oops or even a crash when a return probe is installed on one of the following functions: sys_execve, do_execve, load_*_binary, flush_old_exec, or flush_thread. The fix is to remove the call to kprobe_flush_task() in flush_thread(). This fix has been tested on all architectures for which the return-probes feature has been implemented (i386, x86_64, ppc64, ia64). Please apply. BACKGROUND Up to now, we have called kprobe_flush_task() under two situations: when a task exits, and when it execs. Flushing kretprobe_instances on exit is correct because (a) do_exit() doesn't return, and (b) one or more return-probed functions may be active when a task calls do_exit(). Neither is the case for sys_execve() and its callees. Initially, the mistaken call to kprobe_flush_task() on exec was harmless because we put the "real" return address of each active probed function back in the stack, just to be safe, when we recycled its kretprobe_instance. When support for ppc64 and ia64 was added, this safety measure couldn't be employed, and was eventually dropped even for i386 and x86_64. sys_execve() and its callees were informally blacklisted for return probes until this fix was developed.

Well, arm26 manages it by returning a pte_t pointer cast to a struct page pointer, harumph, then compensating in its pmd_populate. But arm26 is never SMP, so it's not a problem for split ptlock either. And the PA-RISC situation has been recently improved: CONFIG_PA20 works without the 16-byte alignment which inflated its spinlock_t. But the current union of spinlock_t with private does make the 7xxx struct page significantly larger, even without debug, so disable its split ptlock.

The patch below fixes this problem. The problem is specific to 64-bit big endian machines such as s390x or ppc-64 and can prevent pvmove terminating. In the simplest case, if "region_count" were (say) 30, then bitset_size (below) would be 4 and bitset_uint32_count would be 1. Thus the memory for this butset, after allocation and zeroing would be 0 0 0 0 X X X X On a bigendian 64bit machine, bit 0 for this bitset is in the 8th byte! (and every bit that dm-log would use would be in the X area). 0 0 0 0 X X X X ^ here which hasn't been cleared properly. As the dm-raid1 code only syncs and counts regions which have a 0 in the 'sync_bits' bitset, and only finishes when it has counted high enough, a large number of 1's among those 'X's will cause the sync to not complete. It is worth noting that the code uses the same bitsets for in-memory and on-disk logs.

There is no locking in the set_max_huge_pages function around alloc_fresh_huge_page which is able to update nr_huge_pages. Two callers to alloc_fresh_huge_page could race against each other as could a call to alloc_fresh_huge_page and a call to update_and_free_page. This patch just expands the area covered by the hugetlb_lock to cover the call into alloc_fresh_huge_page. I'm not sure how we could say that a sysctl section is performance critical where more specific locking would be needed. My reproducer was to run a couple copies of the following script simultaneously while [ true ]; do echo 1000 > /proc/sys/vm/nr_hugepages echo 500 > /proc/sys/vm/nr_hugepages echo 750 > /proc/sys/vm/nr_hugepages echo 100 > /proc/sys/vm/nr_hugepages echo 0 > /proc/sys/vm/nr_hugepages done and then watch /proc/meminfo and eventually you will see things like HugePages_Total: 100 HugePages_Free: 109 After applying the patch all seemed well.

However, the rest of the vc's were not allocated yet, and when they were subsequently initialized, they still used a font height of 8 (instead of 9) causing the mentioned bug. Fix by saving the new font height to vga_video_font_height.

This is presumably by analogy with the non-compat case, where any non-zero code from copy_to_user() should be translated into an EFAULT. However, put_compat_statfs() is also return -EOVERFLOW. The same applies for put_compat_statfs64(). This bug can be observed with a statfs() on a hugetlbfs directory. hugetlbfs, when mounted without limits reports available, free and total blocks as -1 (itself a bug, another patch coming). statfs() will mysteriously return EFAULT although it's parameters are perfectly valid addresses. This patch causes the compat versions of statfs() and statfs64() to correctly propogate the return values from put_compat_statfs() and put_compat_statfs64().

But many Bad page states reported a PG_reserved was freed after all: I had missed that we need to say __GFP_COMP to get compound page behaviour. Some of these higher-order pages are allocated by snd_malloc_pages, some by snd_malloc_dev_pages; or if SBUS, by sbus_alloc_consistent - but that has no gfp arg, so add __GFP_COMP into its sparc32/64 implementations.

But recognizing them is a little subtle: because PageReserved is no longer a condition for remap_pfn_range, we can now mmap all of /dev/mem (whether the distro permits, and whether it's advisable on this or that architecture, is another matter). So if we can see a PageAnon, it may not be ours to mess with (or may be ours from elsewhere in the address space).

The PageReserved removal in 2.6.15-rc1 changed VM_RESERVED not to free pages in zap_pte_range, without changing those drivers not to set it: so their pages just leak away. Let's not change miscellaneous drivers now: introduce VM_UNPAGED at the core, to flag the special areas where the ptes may have no struct page, or if they have then it's not to be touched. Replace most instances of VM_RESERVED in core mm by VM_UNPAGED. Force it on in remap_pfn_range, and the sparc and sparc64 io_remap_pfn_range. Revert addition of VM_RESERVED to powerpc vdso, it's not needed there. Is it needed anywhere? It still governs the mm->reserved_vm statistic, and special vmas not to be merged, and areas not to be core dumped; but could probably be eliminated later (the drivers are probably specifying it because in 2.4 it kept swapout off the vma, but in 2.6 we work from the LRU, which these pages don't get on). Use the VM_SHM slot for VM_UNPAGED, and define VM_SHM to 0: it serves no purpose whatsoever, and should be removed from drivers when we clean up.

That's just what PageCompound is designed for, but it's been kept under CONFIG_HUGETLB_PAGE.

That nopage is returning a page from within a buffer allocated by snd_malloc_pages, which allocates a high-order page, then does SetPageReserved on each 0-order page within. That would have worked in 2.6.14, because when the area was unmapped, PageReserved inhibited put_page. 2.6.15-rc1 removed that inhibition (while leaving ineffective PageReserveds around for now), but it hasn't caused trouble because.. we've not been freeing from VM_RESERVED at all.

But immediately it caused vbetool and ddcprobe (using lrmi) to fail. So revert the "deprecated" messages, letting mmap and mprotect succeed. But leave do_wp_page's BUG_ON(vma->vm_flags & VM_RESERVED) in place until we've added the code to do it right: so this particular patch is only good if the app doesn't really need to write to that private area.

Because we use syscall6 to remap the stack, the old contents of the stack (and the former value of ebp) are no longer available. Some versions of gcc make from a real local, accessed through ebp, despite my efforts to make it obvious that references to from are really constants. This patch attempts to make it even more obvious by eliminating from and using a macro to access the stub's data explicitly with constants. My original thinking on this was to replace syscall6 with a remap_stack interface which saved ebp someplace and restored it afterwards. The problem is that there are no registers to put it in, except for esp. That could work, since we can store a constant in esp after the mmap because we just replaced the stack. However, this approach seems a tad cleaner.

| 4909724 | Alexandra Kossovsky | 20 November 2005, 21:41:59 UTC | [COMPAT] net: SIOCGIFCONF data corruption From: Alexandra Kossovsky <Alexandra.Kossovsky@oktetlabs.ru> From http://bugzilla.kernel.org/show_bug.cgi?id=4746 There is user data corruption when using ioctl(SIOCGIFCONF) in 32-bit application running amd64 kernel. I do not think that this problem is exploitable, but any data corruption may lead to security problems. Following code demonstrates the problem #include <stdint.h> #include <stdio.h> #include <sys/time.h> #include <sys/socket.h> #include <net/if.h> #include <sys/ioctl.h> char buf[256]; main() { int s = socket(AF_INET, SOCK_DGRAM, 0); struct ifconf req; int i; req.ifc_buf = buf; req.ifc_len = 41; printf("Result %d\n", ioctl(s, SIOCGIFCONF, &req)); printf("Len %d\n", req.ifc_len); for (i = 41; i < 256; i++) if (buf[i] != 0) printf("Byte %d is corrupted\n", i); } Steps to reproduce: Compile the code above into 32-bit elf and run it. You'll get Result 0 Len 32 Byte 48 is corrupted Byte 52 is corrupted Byte 53 is corrupted Byte 54 is corrupted Byte 55 is corrupted Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: David S.

| aa87516 | Andrea Bittau | 20 November 2005, 21:41:05 UTC | [PKT_SCHED]: sch_netem: correctly order packets to be sent simultaneously If two packets were queued to be sent at the same time in the future, their order would be reversed. This would occur because the queue is traversed back to front, and a position is found by checking whether the new packet needs to be sent before the packet being examined. If the new packet is to be sent at the same time of a previous packet, it would end up before the old packet in the queue. This patch places packets in the correct order when they are queued to be sent at a same time in the future. Signed-off-by: Andrea Bittau <a.bittau@cs.ucl.ac.uk> Signed-off-by: David S.

This is due to the differences between asm-i386/msr.h and asm-x86_64/msr.h interfaces. Here is a patch to our side to fix this. Thankfully, as of current (2.6.15-rc1-git6) tree, arch/i386/kernel/msr.c is the only file that uses rdmsr_safe macro.
