abcc944 David Brownell 23 November 2005, 23:45:32 UTC [PATCH] USB: EHCI updates mostly whitespace cleanups This cleans up the recent updates to EHCI PCI support: - Gets rid of checks for "is this a PCI device", they're no longer needed since this is now all PCI-only code. - Reduce log spamming: MWI is only interesting in the atypical case that it can actually be used. - Whitespace cleanup, as appropriate for a new file with no other pending patches. So other than that minor logging change, no functional updates.

f03c17f David Brownell 23 November 2005, 23:45:28 UTC [PATCH] USB: EHCI updates This fixes some bugs in EHCI suspend/resume that joined us over the past few releases (as usbcore, PCI, pmcore, and other components evolved): - Removes suspend and resume recursion from the EHCI driver, getting rid of the USB_SUSPEND special casing. - Updates the wakeup mechanism to work again; there's a newish usbcore call it needs to use. - Provide simpler tests for "do we need to restart from scratch", to address another case where PCI Vaux was lost. (In this case it was restoring a swsusp snapshot, but there could be others.) Un-exports a symbol that was temporarily exported. A notable change from previous version is that this doesn't move the spinlock init, so there's still a resume/reinit path bug.

ed6d14f Rajesh Shah 23 November 2005, 23:44:59 UTC [PATCH] PCI: remove bogus resource collision error When attempting to hotadd a PCI card with a bridge on it, I saw the kernel reporting resource collision errors even when there were really no collisions. The problem is that the code doesn't skip over "invalid" resources with their resource type flag not set. Others have reported similar problems at boot time and for non-bridge PCI card hotplug too, where the code flags a resource collision for disabled ROMs. This patch fixes both problems.

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.

7b6ac9d Hugh Dickins 23 November 2005, 21:37:37 UTC [PATCH] mm: update split ptlock Kconfig Closer attention to the arithmetic shows that neither ppc64 nor sparc really uses one page for multiple page tables: how on earth could they, while pte_alloc_one returns just a struct page pointer, with no offset? 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.

0e56822 Alasdair G Kergon 22 November 2005, 05:32:34 UTC [PATCH] device-mapper: mirror log bitset fix The linux bitset operators (test_bit, set_bit etc) work on arrays of "unsigned long". dm-log uses such bitsets but treats them as arrays of uint32_t, only allocating and zeroing a multiple of 4 bytes (as 'clean_bits' is a uint32_t). 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. As these bitsets are host-endian and host-sized, this means that they cannot safely be moved between computers with Signed-off-by: Neil Brown <neilb@suse.de> Signed-off-by: Alasdair G Kergon <agk@redhat.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org> 22 November 2005, 17:14:31 UTC

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.

The remaining lines are black and not shown. Kernel version 2.6.13.4 does not show this problem." This bug is caused by using a stale font height value on vgacon_init. Booting with vga=1 gives an 80x50 screen with an 8x8 font. Somewhere during the initialization, the font was changed to 8x9 and the first vc was correctly resized to 80x44. 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.

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). I suspect there's an entertaining insoluble self-referential problem here, but the page_is_anon function does a good practical job, and MAP_PRIVATE PROT_WRITE VM_UNPAGED will always be an odd choice.

0b14c17 Hugh Dickins 22 November 2005, 05:32:15 UTC [PATCH] unpaged: VM_UNPAGED Although we tend to associate VM_RESERVED with remap_pfn_range, quite a few drivers set VM_RESERVED on areas which are then populated by nopage. 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 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.

17d4697 Jeff Dike 22 November 2005, 05:32:09 UTC [PATCH] uml: properly invoke x86_64 system calls This patch makes stub_segv use the stub_syscall macros. This was needed anyway, but the bug that prompted this was the discovery that gcc was storing stuff in RCX, which is trashed across a system call. This is exactly the sort of problem that the new macros fix. There is a stub_syscall0 for getpid. stub_segv was changed to be a libc file, and that caused some include changes.

e23181d Jeff Dike 22 November 2005, 05:32:08 UTC [PATCH] uml: eliminate anonymous union and clean up symlink lossage This gives a name to the anonymous union introduced in skas-hold-own-ldt, allowing to build on a wider range of gccs. It also removes ldt.h, which somehow became real, and replaces it with a symlink, and creates ldt-x86_64.h as a copy of ldt-i386.h for now.

39d730a Jeff Dike 22 November 2005, 05:32:04 UTC [PATCH] uml: eliminate use of local in clone stub We have a bug in the i386 stub_syscall6 which pushes ebp before the system call and pops it afterwards. 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.
