Andi Kleen authored
While doing some compat_ioctl conversions I noticed a few issues in compat_sys_ioctl: - It is not completely compatible to old ->ioctl because the traditional common ioctls are not checked before it. I added a check for those. The main advantage is that the handler now works the same as a traditional handler even when it returns -EINVAL - The private socket ioctl check should only apply for sockets. - There was a security hook missing. Drawback is that it uses the same hook now, and the LSM module cannot distingush between 32bit and 64bit clients. But it'll have to live with that for now. Signed-off-by:

Adds 3 new completion API calls, which are a straightforward extension of the current APIs: int wait_for_completion_interruptible(struct completion *x); unsigned long wait_for_completion_timeout(struct completion *x, unsigned long timeout); unsigned long wait_for_completion_interruptible_timeout( struct completion *x, unsigned long timeout); This enables the conversion of more semaphore-using code to completions. There is code that cannot be converted right now (and is forced to use semaphores) because these primitives are missing. Thomas Gleixner has a bunch of patches to make use of them.

This patch fixes counting of unhandled messages. Messages that were handled internally by the driver (to the NULL user) were miscounted as unhanlded responses. This counts them properly. This patch also fixes the DMI 16-byte setting, which was set as a 16-bit setting. It also uses the right value to initilize the address memory when using a memory-based interface. Signed-off-by:

To convert page->index to a byte index you need to cast it to loff_t first so it's a 64bit value. There have been quite a few places that got it wrong in the kernel. To make it easier a nice little helper would be nice, and in fact the NFS code already has it. Let's move it to pagemap.h so everyone can use it. Signed-off-by:

sa_handler isn't the first member of struct sigaction on mips. Use C99 initializers to avoid a compiler warning. (There don't seem to be more serious problems as mips worked with that warning for ages) Signed-off-by:

Compiling an allyesconfig kernel straight with a gcc 4.0 snapshot gives nearly 10k new warnings like: warning: pointer targets in passing argument 5 of `cpuid' differ in signedness Since the sheer number of these warnings was too much even for the most determined kernel janitors (I actually asked ;-) and I don't think it's a very serious issue to have these mismatches I submitted an new option to gcc to disable it. It was incorporated in gcc mainline now. This patch makes the kernel compilation use it. There are still quite a lot of new warnings with 4.0 (mostly about uninitialized variables), but the compile log looks much nicer nnow. Signed-off-by:

Most of the include/asm-*/resource.h headers are the same as one another. This patch makes one generic version, include/asm-generic/resource.h, and uses that when appropriate. The only vaguely interesting things here are that the generic version introduces a new _STK_LIM_MAX macro, which can be populated by an arch (ia64 and parisc needed that). Also, some arches hid RLIM_INFINITY under __KERNEL__, while others did not. The generic version does not, so the following arches will see that change: arm, arm26, mips, ppc, ppc64, sh (and hence sh64) And, finally, some arches maintain their own order for the resource numbers. This is now marked by __ARCH_RLIMIT_ORDER, and is used by the following arches: alpha, mips, sparc, and sparc64. This actually uncovered a mips bug (fix already sent, this patch is relative to that fix), where the default RLIMIT_MEMLOCK was set to RLIM_INFINITY and RLIMIT_NPROC set to MLOCK_LIMIT (the latter is no big deal because RLIMIT_NPROC default is overwritten dynamically during bootup in fork_init()). Also, this change makes alpha's default for RLIMIT_NPROC change from RLIM_INFINITY to 0, but again...no problem as it's dynamically overwritten during bootup. The following arches are left untouched: m68knommu: untouched (uses m68k/resource.h) sh64: untouched (uses asm-sh/resource.h) um: untouched (uses arch code already) Signed-off-by:Chris Wright <chrisw@osdl.org> Signed-off-by:

I have a problem with errors=panic on ext3. When a panic occurs, the error event is not recorded anywhere. So after the reboot, e2fsck doesn't kick in, the file system gets mounted again and the box panics again... Patch below moves the ERRORS_PANIC test down a bit so the journal is aborted before panic() is called. Signed-off-by:

The use of U+F800 to U+F804 has been deprecated since 2003; this makes the deprecation effective by replacing these characters with the officially assigned U+23BA to U+23BD. It also updates unicode.txt to match the latest version from the LANANA webpage. Signed-off-by:

So far the X.Org/XFree86 Xservers use internal functions to perform saving/restoring of console fonts. This doesn't work under all circumstances and has disadvantages: 1. On some platforms (IA64) X needs to POST the BIOS before it even has a chance to access the hardware itself. This POSTing will usually undo any changes to the graphics hardware that the kernel may have done. 2. More and more drivers fully rely on BIOS support. However the BIOS functions which could be used to save/restore register settings may be broken so the only way of mode save/restore is getting/setting the BIOS mode ID. This will restore the BIOSes default fonts, not the custom font that the user may have loaded. I would like to utilize the kernel's save/restore console fonts ioctls to save/restore the text mode console fonts from inside X. The patch does two things: 1. Eliminates the optimization that returns from vgacon_adjust_height() early (without reprogramming the HW) when the hight of the font hasn't changed. 2. Resets the stored 'from' and 'to' lines for the text cursor in vgacon_adjust_height() to cause vgacon_set_cursor_size() reprogram the textcursor start and end line. These are necessary to sanitize the HW in case something other than the kernel has changed the register values without restoring them properly. I'm fully aware that in the long run we will need to look into a new driver model for graphics where no two instances fight over who gets register access. However such a model won't be created nor will we get the majority of the drivers ported over night. Therefore we need to find an interim solution for the most pressing problems. Signed-off-by:

Currently it's up to the filesystem ->permission method to check whether the filesystem is readonly or the file marked immutable. But this is really a VFS decision, and the distintion becomes more important when moving to per-mountpoint read only flags. For most filesystems that have been using generic_permission this is not change in behaviour. For those that we're missing the check (cifs without CIFS_MOUNT_NO_PERM and coda [1]) this is a bugfix. Both reiserfs and xfs have this check still in their ->permission routine because they call it from other places aswell. I'll try switching them over to generic_permission and will take care of this one. [1] coda_ioctl_permission always returns 0, aka always grants access, which looks more than fishy to me.

expand_files() cleanup: Make expand_files() common code for fork.c:fork/copy_files(), open.c:open/get_unused_fd() and fcntl.c:dup/locate_fd(). expand_files() does both expand_fd_array and expand_fd_set based on the need. This is used in dup(). open() and fork() duplicates the work of expand files. At all places we check for expanding fd array, we also check for expanding fdset. There is no need of checking and calling them seperately. This change also moves the expand_files to file.c from fcntl.c, and makes the expand_fd_array and expand_fd_set local to that file.

This passes pm_message_t down to PCI drivers. Ugly translation code can be removed and this will allow PCI devices to do right thing during swsusp snapshot -- like not unneccessarily blanking display. Only obscure /sysfs code passes anything but 3 to pci_device_suspend, anyway, so this is pretty close to a nop. Signed-off-by:
