idr_remove() should fail gracefully and warn if the id being removed is not valid. The attached patch should do the job without additional overhead. With the existing code, removing an id which was not allocated could remove a valid id which shares the same lowest layer of the radix tree. I ran a kernel with this patch but have not done any tests to force a failure. Signed-off-by:

This is needed for an mmtimer driver update that we are currently working on. The mmtimer driver provides CLOCK_SGI_CYCLE via clock_gettime and clock_settime. With this api fix one will be able to use timer_create, timer_settime and friends from userspace to schedule and receive signals via timer interrupts of mmtimer. Changelog * Clean up timer api for drivers that use register_posix_clock. Drivers will then be able to use posix timers to schedule interrupts. * Change API for posix_clocks[].timer_create to only pass one pointer to a k_itimer structure that is now allocated and managed by the posix layer in the same way as for the other posix timer functions. * Isolate a posix_timer_event(timr) function in posix-timers.c that may be called by the interrupt routine of a timer to signal that the scheduled event has taken place.

This patch against 2.6.9 adds a DAC ownership check to the existing MAC permission checks when setting the security.selinux attribute via setxattr. In the past, the MAC permission checks were viewed as sufficient for controlling relabeling operations, but experience in the Fedora SELinux integration has shown that a DAC check is also appropriate here, particularly under targeted policy.

In 2.2, you used to just be able to call functions "init_module" and "cleanup_module" and they'd be magically called. These days you should use module_init(myinit)/module_exit(myexit) and avoid #ifdef MODULE. Signed-off-by:

As noticed by Joey Hess (and thanks for Christoph for forwarding it). Also requirements from Werner Almesberger. If someone passes 'foo="some value"' the param engine removes the quotes and hands 'foo' and 'some value'. The __setup() parameters expect a single string, and so we try to regenerate it from the two parts. Finally, we try to place it as an environment variable. Werner wants quotes stripped out of the environment variable. It makes sense to do that for __setup, too (so it sees 'foo=some value'), since __setup functions don't usually handle quotes.

Currently, only module parameters in loaded modules are exported in /sys/modules/, while those of "modules" built into the kernel can be set by the kernel command line, but not read or set via sysfs. - move module parameters from /sys/modules/$(module_name)/$(parameter_name) to /sys/modules/$(module_name)/parameters/$(parameter_name) - remove dummy kernel_param for exporting refcnt, add "struct module *"-based attribute instead - also export module paramters for "modules" which are built into the kernel, so parameters are always accessible at /sys/modules/$(KBUILD_MODNAME)/$(parameter_name) Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (modified) Signed-off-by:

The session leader should disassociate from its controlling terminal and send SIGHUP signals only when the whole session leader process dies. Currently, this gets done when any thread in that process dies, which is wrong. This patch fixes it. Signed-off-by:

This patch changes process accounting to write just one record for a process with many NPTL threads, rather than one record for each thread. No record is written until the last thread exits. The process's record shows the cumulative time of all the threads that ever lived in that process (thread group). This seems like the clearly right thing and I assume it is what anyone using process accounting really would like to see. There is a race condition between multiple threads exiting at the same time to decide which one should write the accounting record. I couldn't think of anything clever using existing bookkeeping that would get this right, so I added another counter for this. (There may be some potential to clean up existing places that figure out how many non-zombie threads are in the group, now that this count is available.) Signed-off-by:

The current cursor interface is confusing. Some fields are taken from the cursor structure in struct fb_info (enable, mask, rop fields) and the rest are taken from the passed cursor structure. These lead to a lot of confusion, making it hard for developers to write their own implementation. Also, the cursor code has several 'short-circuits', occassionally leading to undefined cursor behavior. These are the changes brought about by the patch: - Removed struct fb_cursor and related fields from struct fb_info, and instead, placed them in a struct not visible to fbdev. - The struct fb_cursor passed to fb_cursor() will _always_ contain valid data with various bitflags indicating which fields have changed - The struct fb_pixmap sprite in struct fb_info is used only by drivers with hardware cursor implementation. Initializing and allocating memory for this structure is not needed. Remove initialization and memory allocation. - The FBIO_CURSOR ioctl is broken (because fb_cursor() is broken). For now, remove fb_cursor code and make the FBIO_CURSOR ioctl always return -ENODEV. - The flag FB_CUR_SETCUR is changed to FB_CUR_SETIMAGE, indicating that the cursor sprite has changed. The image change is now checked by fbcon so drivers will not unnecessarily load the sprite image everytime. This causes hardware cursors to flicker, especially in rivafb. - Remove fb_load_cursor_image(). This is unused, and should not be implemented generically. - Documented the usage of the cursor interface in skeletonfb.c Signed-off-by:

This patch adds a new IV mode ''encrypted sector|salt IV'' described in http://article.gmane.org/gmane.linux.kernel.device-mapper.dm-crypt/472 To use ESSIV, set the ivmode (using the new syntax) to "essiv:<hash>". "hash" should be a valid cryptoapi hash. This, for example, is a valid dm-target line: 0 200 crypt aes-cbc-essiv:sha256 00000000000000000000000000000000 0 /dev/loop/5 0 Signed-Off-By:

Create crypt_iv_operations structure with generator method and move the plain iv generator into this structure. Optionally accept an extended <sector format> syntax: <cipher>-<chaining mode>-<iv mode> This also makes it ready to support chaining modes other than CBC mode, such as CMC (not implemented in cryptoapi yet), The problems outlined by Adam J. Richter in http://article.gmane.org/gmane.linux.kernel.device-mapper.dm-crypt/454 would be fixed by switching to CMC chaining mode.
