caefba1 Hugh Dickins 13 April 2009, 21:40:12 UTC shmem: respect MAX_LFS_FILESIZE SHMEM_MAX_BYTES was derived from the maximum size of its triple-indirect swap vector, forgetting to take the MAX_LFS_FILESIZE limit into account. Never mind 256kB pages, even 8kB pages on 32-bit kernels allowed files to grow slightly bigger than that supposed maximum. Fix this by using the min of both (at build time not run time). And it happens that this calculation is good as far as 8MB pages on 32-bit or 16MB pages on 64-bit: though SHMSWP_MAX_INDEX gets truncated before that, it's truncated to such large numbers that we don't need to care.

61609d0 Yuri Tikhonov 13 April 2009, 21:40:11 UTC shmem: fix division by zero Fix a division by zero which we have in shmem_truncate_range() and shmem_unuse_inode() when using big PAGE_SIZE values (e.g. 256kB on ppc44x). With 256kB PAGE_SIZE, the ENTRIES_PER_PAGEPAGE constant becomes too large (0x1.0000.0000) on a 32-bit kernel, so this patch just changes its type from 'unsigned long' to 'unsigned long long'. Hugh: reverted its unsigned long longs in shmem_truncate_range() and shmem_getpage(): the pagecache index cannot be more than an unsigned long, so the divisions by zero occurred in unreached code. It's a pity we need any ULL arithmetic here, but I found no pretty way to avoid it.

d20d5a7 Randy Robertson 13 April 2009, 21:40:04 UTC initramfs: fix initramfs to work with hardlinked init Change cb6ff208076b5f434db1b8c983429269d719cef5 ("NOMMU: Support XIP on initramfs") seems to have broken booting from initramfs with /sbin/init being a hardlink. It seems like the logic required for XIP on nommu, i.e. ftruncate to reported cpio header file size (body_len) is broken for hardlinks, which have a reported size of 0, and the truncate thus nukes the contents of the file (in my case busybox), making boot impossible and ending with runaway loop modprobe binfmt-0000 - and of course 0000 is not a valid binary format. My fix is to only call ftruncate if size is non-zero which fixes things for me, but I'm not certain whether this will break XIP for those files on nommu systems, although I would guess not.

f1671f6 Oleg Nesterov 13 April 2009, 21:40:03 UTC ptrace: fix exit_ptrace() vs ptrace_traceme() race Pointed out by Roland. The bug was recently introduced by me in "forget_original_parent: split out the un-ptrace part", commit 39c626ae47c469abdfd30c6e42eff884931380d6. Since that patch we have a window after exit_ptrace() drops tasklist and before forget_original_parent() takes it again. In this window the child can do ptrace(PTRACE_TRACEME) and nobody can untrace this child after that. Change ptrace_traceme() to not attach to the exiting ->real_parent. We don't report the error in this case, we pretend we attach right before ->real_parent calls exit_ptrace() which should untrace us anyway.

bdff549 David Brownell 13 April 2009, 21:39:57 UTC spi: spi_write_then_read() bugfixes The "simplify spi_write_then_read()" patch included two regressions from the 2.6.27 behaviors: - The data it wrote out during the (full duplex) read side of the transfer was not zeroed. - It fails completely on half duplex hardware, such as Microwire and most "3-wire" SPI variants. So, revert that patch. A revised version should be submitted at some point, which can get the speedup on standard hardware (full duplex) without breaking on less-capable half-duplex stuff.

251eb40 Jonathan Cameron 13 April 2009, 21:39:45 UTC hwmon: sht15 humidity sensor driver Data sheet at: http://www.sensirion.ch/en/pdf/product_information/Datasheet-humidity-sensor-SHT1x.pdf These sensors communicate over a 2 wire bus running a device specific protocol. The complexity of the driver is mainly due to handling the substantial delays between requesting a reading and the device pulling the data line low to indicate that the data is available. This is handled by an interrupt that is disabled under all other conditions. I wasn't terribly clear on the best way to handle this, so comments on that aspect would be particularly welcome! Interpretation of the temperature depends on knowing the supply voltage. If configured in a board config as a regulator consumer this is obtained from the regulator subsystem. If not it should be provided in the platform data. I've placed this driver in the hwmon subsystem as it is definitely a device that may be used for hardware monitoring and with it's relatively slow response times (up to 120 millisecs to get a reading) a caching strategy certainly seems to make sense!

Wysocki 12 April 2009, 18:06:56 UTC PM/Hibernate: Wait for SCSI devices scan to complete during resume There is a race between resume from hibernation and the asynchronous scanning of SCSI devices and to prevent it from happening we need to call scsi_complete_async_scans() during resume from hibernation. In addition, if the resume from hibernation is userland-driven, it's better to wait for all device probes in the kernel to complete before attempting to open the resume device.

0ad30b8 Serge E. Hallyn 13 April 2009, 14:56:14 UTC add some long-missing capabilities to fs_mask When POSIX capabilities were introduced during the 2.1 Linux cycle, the fs mask, which represents the capabilities which having fsuid==0 is supposed to grant, did not include CAP_MKNOD and CAP_LINUX_IMMUTABLE. However, before capabilities the privilege to call these did in fact depend upon fsuid==0. This patch introduces those capabilities into the fsmask, restoring the old behavior. See the thread starting at http://lkml.org/lkml/2009/3/11/157 for reference. Note that if this fix is deemed valid, then earlier kernel versions (2.4 and 2.2) ought to be fixed too.

This might be convenient to ignore bad locking issues which sources come from outside the kernel tree. Nevertheless, it might be a frustrating experience for the staging developers or those who experience a warning but are focused on another things that require lockdep. The v2 of this patch simply don't disable anymore lockdep in case of TAINT_CRAP and TAINT_WARN events.

9eeba61 Frederic Weisbecker 11 April 2009, 01:17:17 UTC lockdep: warn about lockdep disabling after kernel taint Impact: provide useful missing info for developers Kernel taint can occur in several situations such as warnings, load of prorietary or staging modules, bad page, etc... But when such taint happens, a developer might still be working on the kernel, expecting that lockdep is still enabled. But a taint disables lockdep without ever warning about it. Such a kernel behaviour doesn't really help for kernel development. This patch adds this missing warning. Since the taint is done most of the time after the main message that explain the real source issue, it seems safe to warn about it inside add_taint() so that it appears at last, without hurting the main information. v2: Use a generic helper to disable lockdep instead of an open coded xchg().

d6de2c8 Linus Torvalds 10 April 2009, 19:17:41 UTC async: Fix module loading async-work regression Several drivers use asynchronous work to do device discovery, and we synchronize with them in the compiled-in case before we actually try to mount root filesystems etc. However, when compiled as modules, that synchronization is missing - the module loading completes, but the driver hasn't actually finished probing for devices, and that means that any user mode that expects to use the devices after the 'insmod' is now potentially broken. We already saw one case of a similar issue in the ACPI battery code, where the kernel itself expected the module to be all done, and unmapped the init memory - but the async device discovery was still running. That got hacked around by just removing the "__init" (see commit 5d38258ec026921a7b266f4047ebeaa75db358e5 "ACPI battery: fix async boot oops"), but the real fix is to just make the module loading wait for all async work to be completed. It will slow down module loading, but since common devices should be built in anyway, and since the bug is really annoying and hard to handle from user space (and caused several S3 resume regressions), the simple fix to wait is the right one. This fixes at least http://bugzilla.kernel.org/show_bug.cgi?id=13063 but probably a few other bugzilla entries too (12936, for example), and is confirmed to fix Rafael's storage driver breakage after resume bug report (no bugzilla entry). We should also be able to now revert that ACPI battery fix. Reported-and-tested-by: Rafael J.

9e5ec86 Maxime Bizon 09 February 2009, 17:49:52 UTC kbuild: fix spurious initramfs rebuild When gen_initramfs_list is used to generate make dependencies, it includes symbolic links, for which make tracks the link target. Any change to that target will cause an initramfs rebuild, even if the symlink points to something outside of the initramfs directory. If the target happens to be /tmp, the rebuild occurs for each kernel build, since gen_initramfs_list uses mktemp... Proposed way to fix it is to omit symbolic links from generated dependencies, but this has a small drawback: changing perm/owner on a symlink will go unnoticed.

5d7d18f David Howells 04 March 2009, 19:59:07 UTC kbuild: make it possible for the linker to discard local symbols from vmlinux Make it possible for the linker to discard local symbols from vmlinux as they cause vmlinux to balloon when CONFIG_KALLSYMS=y and they cause dump_stack() and get_wchan() to produce useless information under some circumstances. With this we add a config option (CONFIG_STRIP_ASM_SYMS) that will cause the build to supply -X to the linker to tell it to strip temporary local symbols. This doesn't seem to cause gdb any problems.

612c280 Sam Ravnborg 08 April 2009, 06:42:48 UTC kconfig: fix update-po-config to accect backslash in input Massimo Maiurana reported (slightly edited): ===== In latest 2.6.29 "make update-po-config" fails at msguniq invocation with an "invalid control sequence" error. The offending string is the following, and it's located in drivers/staging/panel/Kconfig:72: "'\e[L' which are specific to the LCD, and a few ANSI codes. The" looks to me like gettext expects strings in printf format, so in this case it thinks "\e" is a control sequence but doesn't recognise it as a valid one. A valid solution would be to tell kxgettext to automatically escape this kind of strings in the */config.pot he produces, so that msguniq would not complain. ===== This patch implements the suggested escaping.
