887c3cb Yasunori Goto 15 November 2007, 00:59:20 UTC Add IORESOUCE_BUSY flag for System RAM i386 and x86-64 registers System RAM as IORESOURCE_MEM | IORESOURCE_BUSY. But ia64 registers it as IORESOURCE_MEM only. In addition, memory hotplug code registers new memory as IORESOURCE_MEM too. This difference causes a failure of memory unplug of x86-64. This patch fixes it. This patch adds IORESOURCE_BUSY to avoid potential overlap mapping by PCI device.

5fce25a Peter Zijlstra 15 November 2007, 00:59:15 UTC mm: speed up writeback ramp-up on clean systems We allow violation of bdi limits if there is a lot of room on the system. Once we hit half the total limit we start enforcing bdi limits and bdi ramp-up should happen. Doing it this way avoids many small writeouts on an otherwise idle system and should also speed up the ramp-up.

3ad33b2 Lee Schermerhorn 15 November 2007, 00:59:10 UTC Migration: find correct vma in new_vma_page() We hit the BUG_ON() in mm/rmap.c:vma_address() when trying to migrate via mbind(MPOL_MF_MOVE) a non-anon region that spans multiple vmas. For anon-regions, we just fail to migrate any pages beyond the 1st vma in the range. This occurs because do_mbind() collects a list of pages to migrate by calling check_range(). check_range() walks the task's mm, spanning vmas as necessary, to collect the migratable pages into a list. Then, do_mbind() calls migrate_pages() passing the list of pages, a function to allocate new pages based on vma policy [new_vma_page()], and a pointer to the first vma of the range. For each page in the list, new_vma_page() calls page_address_in_vma() passing the page and the vma [first in range] to obtain the address to get for alloc_page_vma(). The page address is needed to get interleaving policy correct. If the pages in the list come from multiple vmas, eventually, new_page_address() will pass that page to page_address_in_vma() with the incorrect vma. For !PageAnon pages, this will result in a bug check in rmap.c:vma_address(). For anon pages, vma_address() will just return EFAULT and fail the migration. This patch modifies new_vma_page() to check the return value from page_address_in_vma(). If the return value is EFAULT, new_vma_page() searchs forward via vm_next for the vma that maps the page--i.e., that does not return EFAULT. This assumes that the pages in the list handed to migrate_pages() is in address order. This is currently case. The patch documents this assumption in a new comment block for new_vma_page(). If new_vma_page() cannot locate the vma mapping the page in a forward search in the mm, it will pass a NULL vma to alloc_page_vma(). This will result in the allocation using the task policy, if any, else system default policy. This situation is unlikely, but the patch documents this behavior with a comment. Note, this patch results in restarting from the first vma in a multi-vma range each time new_vma_page() is called. If this is not acceptable, we can make the vma argument a pointer, both in new_vma_page() and it's caller unmap_and_move() so that the value held by the loop in migrate_pages() always passes down the last vma in which a page was found. This will require changes to all new_page_t functions passed to migrate_pages(). Is this necessary? For this patch to work, we can't bug check in vma_address() for pages outside the argument vma. This patch removes the BUG_ON(). All other callers [besides new_vma_page()] already check the return status. Tested on x86_64, 4 node NUMA platform.

8cd8fa5 Jeff Dike 15 November 2007, 00:58:53 UTC uml: update address space affected by pud_clear pud_clear wasn't setting the _PAGE_NEWPAGE bit, fooling tlb_flush into thinking that this area of the address space was up-to-date and not unmapping whatever was covered by the pud. This manifested itself as ldconfig on x86_64 complaining about the first library it looked at not being a valid ELF file. A config file is mapped at 0x4000000, as the only thing mapped under its pud, and unmapped. The unmapping caused a pud_clear, which, due to this bug, didn't actually unmap the config file data on the host. The first library is then mapped at the same location, but is not actually mapped on the host because accesses to it cause no page faults. As a result, ldconfig sees the old config file data.

a4b1d50 David Brownell 15 November 2007, 00:58:30 UTC RTCs: handle NVRAM better Several of the RTC drivers are exporting binary "nvram" files in sysfs. Such NVRAM (or on many systems, EEPROM) data is often initialized during system manufacture to hold data about identity (serial numbers, Ethernet addresses, etc), configuration, calibration, and so forth. This patch improves integrity and security of those files: - Correctly initializes the size in one of the two cases where that was not yet being done. - Improves system security/integrity by making this state not be world-writable by default. Letting arbitrary userspace code mangle such state by default is at least Not A Good Thing; and it could sometimes be worse, depending on the particular data that might be corrupted. (I disregard the paranoiac "don't let anyone read it either" approach. Anyone storing passwords in such memory doesn't really care about security.)

0b832a4 Linus Torvalds 13 November 2007, 16:07:31 UTC Revert "ext2/ext3/ext4: add block bitmap validation" This reverts commit 7c9e69faa28027913ee059c285a5ea8382e24b5d, fixing up conflicts in fs/ext4/balloc.c manually. The cost of doing the bitmap validation on each lookup - even when the bitmap is cached - is absolutely prohibitive. We could, and probably should, do it only when adding the bitmap to the buffer cache. However, right now we are better off just reverting it. Peter Zijlstra measured the cost of this extra validation as a 85% decrease in cached iozone, and while I had a patch that took it down to just 17% by not being _quite_ so stupid in the validation, it was still a big slowdown that could have been avoided by just doing it right.

b64f87c Becky Bruce 09 November 2007, 22:17:49 UTC [POWERPC] Avoid unpaired stwcx. on some processors The context switch code in the kernel issues a dummy stwcx. to clear the reservation, as recommended by the architecture. However, some processors can have issues if this stwcx to address A occurs while the reservation is already held to a different address B. To avoid this problem, the dummy stwcx. needs to be paired with a dummy lwarx to the same address. This adds the dummy lwarx, and creates a cpu feature bit to indicate which cpus are affected. Tested on mpc8641_hpcn_defconfig in arch/powerpc; build tested in arch/ppc.

This happens because of a hardware bug in the new CPMU. During normal operation, the MAC depends on the PHY clock being available. When the PHY is powered down, the clock the MAC depends on is disabled. The fix is to switch the MAC clock to an alternate source before powering down the PHY, and to restore the MAC clock to the PHY source upon device resume.

c88864d Matt Carlson 13 November 2007, 05:07:01 UTC [TG3]: Fix 5761 PXEboot crash When 5761 devices boot the machine using PXEboot, PXE leaves the device active when it terminates. The tg3 driver has code to detect this condition and resets the device during initialization. On 5761 devices, device resets involve sending a driver state update message to the APE on the 5761. However, during this initialization stage, communications to the APE registers have not yet been set up. The driver then dereferences a NULL pointer and crashes the machine. The fix is to move the APE register access setup earlier in the initialization code to cover this condition.

62768e2 Johannes Berg 13 November 2007, 02:09:25 UTC [SUNGEM]: Fix suspend regression due to NAPI changes. Commit bea3348e (the NAPI changes) made sungem unconditionally enable NAPI when resuming and unconditionally disable when suspending, this, however, makes napi_disable() hang when suspending when the interface was taken down before suspend because taking the interface down also disables NAPI. This patch makes touching the napi struct in suspend/resume code paths depend on having the interface up, thereby fixing the hang on suspend. The patch also moves the napi_disable() in gem_close() under the lock so that the NAPI state is always modified atomically together with the "opened" variable.

325d22d Roland McGrath 12 November 2007, 23:41:55 UTC sigwait eats blocked default-ignore signals While a signal is blocked, it must be posted even if its action is SIG_IGN or is SIG_DFL with the default action to ignore. This works right most of the time, but is broken when a sigwait (rt_sigtimedwait) is in progress. This changes the early-discard check to respect real_blocked. ~blocked is the set to check for "should wake up now", but ~(blocked|real_blocked) is the set for "blocked" semantics as defined by POSIX.

6fa0283 J.

Without this fix it is possible, for example, to traverse from an export without the secure ports requirement to one with it in a single compound, and bypass the secure port check on the new export. While we're here, fix up some minor style problems and change a printk() to a dprintk(), to make it harder for random unprivileged users to spam the logs. Signed-off-by: J.

00ec99d Roland McGrath 12 November 2007, 03:13:43 UTC core dump: remain dumpable The coredump code always calls set_dumpable(0) when it starts (even if RLIMIT_CORE prevents any core from being dumped). The effect of this (via task_dumpable) is to make /proc/pid/* files owned by root instead of the user, so the user can no longer examine his own process--in a case where there was never any privileged data to protect. This affects e.g. auxv, environ, fd; in Fedora (execshield) kernels, also maps. In practice, you can only notice this when a debugger has requested PTRACE_EVENT_EXIT tracing. set_dumpable was only used in do_coredump for synchronization and not intended for any security purpose. (It doesn't secure anything that wasn't already unsecured when a process dies by SIGTERM instead of SIGQUIT.) This changes do_coredump to check the core_waiters count as the means of synchronization, which is sufficient. Now we leave the "dumpable" bits alone.

But as Anthony Liguori points out, the free-running indices used by virtio require that the sizes be a power of 2, otherwise we get problems on wrap (demonstrated with lguest). So we replace the clever "2^n-1" scheme with a simple "align to page boundary" scheme: this means that all virtio rings take at least two pages, but it's safer than guessing cache alignment.
