* [CIFS] Avoid open on possible directories since Samba now rejects themSteve French2009-05-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Small change (mostly formatting) to limit lookup based open calls to file create only. After discussion yesteday on samba-technical about the posix lookup regression, and looking at a problem with cifs posix open to one particular Samba version, Jeff and JRA realized that Samba server's behavior changed in this area (posix open behavior on files vs. directories). To make this behavior consistent, JRA just made a fix to Samba server to alter how it handles open of directories (now returning the equivalent of EISDIR instead of success). Since we don't know at lookup time whether the inode is a directory or file (and thus whether posix open will succeed with most current Samba server), this change avoids the posix open code on lookup open (just issues posix open on creates). This gets the semantic benefits we want (atomicity, posix byte range locks, improved write semantics on newly created files) and file create still is fast, and we avoid the problem that Jeff noticed yesterday with "openat" (and some open directory calls) of non-cached directories to one version of Samba server, and will work with future Samba versions (which include the fix jra just pushed into Samba server). I confirmed this approach with jra yesterday and with Shirish today. Posix open is only called (at lookup time) for file create now. For opens (rather than creates), because we do not know if it is a file or directory yet, and current Samba no longer allows us to do posix open on dirs, we could end up wasting an open call on what turns out to be a dir. For file opens, we wait to call posix open till cifs_open. It could be added here (lookup) in the future but the performance tradeoff of the extra network request when EISDIR or EACCES is returned would have to be weighed against the 50% reduction in network traffic in the other paths.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent PCI PM changes introduced a bug that causes some devices to be mishandled after kexec and during early initialization. The failure scenario in the kexec case is the following: * Assume a PCI device is not power-manageable by the platform and has PCI_PM_CTRL_NO_SOFT_RESET set in PMCSR. * The device is put into D3 before kexec (using the native PCI PM). * After kexec, pci_setup_device() sets the device's power state to PCI_UNKNOWN. * pci_set_power_state(dev, PCI_D0) is called by the device's driver. * __pci_start_power_transition(dev, PCI_D0) is called and since the device is not power-manageable by the platform, it causes pci_update_current_state(dev, PCI_D0) to be called. As a result the device's current_state field is updated to PCI_D3, in accordance with the contents of its PCI PM registers. * pci_raw_set_power_state() is called and it changes the device power state to D0. *However*, it should also call pci_restore_bars() to reinitialize the device, but it doesn't, because the device's current_state field has been modified earlier. To prevent this from happening, modify pci_platform_power_transition() so that it doesn't use pci_update_current_state() to update the current_state field for devices that aren't power-manageable by the platform. Instead, this field should be updated directly for devices that don't support the native PCI PM. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>

| * | drm: Round size of SHM maps to PAGE_SIZEBenjamin Herrenschmidt2009-05-19
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, userspace can fail to obtain the SAREA mapping (among other reasons) if it passes SAREA_MAX to drmAddMap without aligning it to the page size. This breaks for example on PowerPC with 64K pages and radeon despite the kernel radeon actually doing the right rouding in the first place. The way SAREA_MAX is defined with a bunch of ifdef's and duplicated between libdrm and the X server is gross, ultimately it should be retrieved by userspace from the kernel, but in the meantime, we have plenty of existing userspace built with bad values that need to work. This patch works around broken userspace by rounding the requested size in drm_addmap_core() of any SHM map to the page size. Since the backing memory for SHM maps is also allocated within addmap_core, there is no danger of adjacent memory being exposed due to the increased map size. The only side effect is that drivers that previously tried to create or access SHM maps using a size < PAGE_SIZE and failed (getting -EINVAL), will now succeed at the cost of a little bit more memory used if that happens to be when the map is created.

In FLATMEM, it is expected that holes always have valid memmap as long as there is valid PFNs either side of the hole. In SPARSEMEM, it is assumed that a valid section has a memmap for the entire section. However, ARM and maybe other embedded architectures in the future free memmap backing holes to save memory on the assumption the memmap is never used. The page_zone linkages are then broken even though pfn_valid() returns true. A walker of the full memmap must then do this additional check to ensure the memmap they are looking at is sane by making sure the zone and PFN linkages are still valid. This is expensive, but walkers of the full memmap are extremely rare. This was caught before for FLATMEM and hacked around but it hits again for SPARSEMEM because the page_zone linkages can look ok where the PFN linkages are totally screwed. This looks like a hatchet job but the reality is that any clean solution would end up consumning all the memory saved by punching these unexpected holes in the memmap. For example, we tried marking the memmap within the section invalid but the section size exceeds the size of the hole in most cases so pfn_valid() starts returning false where valid memmap exists. Shrinking the size of the section would increase memory consumption offsetting the gains. This patch identifies when an architecture is punching unexpected holes in the memmap that the memory model cannot automatically detect and sets ARCH_HAS_HOLES_MEMORYMODEL. At the moment, this is restricted to EP93xx which is the model sub-architecture this has been reported on but may expand later. When set, walkers of the full memmap must call memmap_valid_within() for each PFN and passing in what it expects the page and zone to be for that PFN. If it finds the linkages to be broken, it assumes the memmap is invalid for that PFN. Signed-off-by: Mel Gorman <mel@csn.ul.ie> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

It also allows the uart clocks to be stopped when there are no users.

So the definition needs to be 4. This fixes also a cold reset HW bug in OMAP3430 ES3.x where some of the efuse bits are not isolated during wake-up from off mode. This can cause randomish cold resets with off mode. Enabling the USBTLL hardware SAVEANDRESTORE causes the core power up assert to be delayed in a way that we will not get faulty values when boot ROM is reading the unisolated registers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the clkdev, musb_core.c needs to register clock with name "ick". Once all the platforms using the musb driver have been converted to use clockdev, the clock name does not need to be passed from the low-level init code.

This is not needed, arch/arm/plat-s3c/clock.c cannot be compiled as a module, and even if it was, it should not be playing with this field if it being registered from somewhere else. The best course of action is to remove this bit of code completely. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
