* Bluetooth: Add HCIUARTSETFLAGS and HCIUARTGETFLAGS ioctlsJohan Hedberg2010-07-211-0/+2
| | | | | | | | | | | This patch introduces two new ioctls: HCIUARTSETFLAGS and HCIUARTGETFLAGS. The only flag available for now is HCI_UART_RAW_DEVICE which allows to initialize a UART device into RAW mode from userspace. This is particularly useful for experimenting with Bluetooth controllers that don't yet have proper support in BlueZ.

* Bluetooth: Add blacklist support for incoming connectionsJohan Hedberg2010-07-211-0/+2
| | | | | | | | | | | In some circumstances it could be desirable to reject incoming connections on the baseband level. This patch adds this feature through two new ioctl's: HCIBLOCKADDR and HCIUNBLOCKADDR. Both take a simple Bluetooth address as a parameter. BDADDR_ANY can be used with HCIUNBLOCKADDR to remove all devices from the blacklist. Signed-off-by: Johan Hedberg <johan.hedberg@nokia.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
* pktcdvd: improve BKL and compat_ioctl.c usageArnd Bergmann2010-04-291-3/+0
| | | | | | | | | | | | The pktcdvd driver uses proper locking and does not need the BKL in the ioctl and llseek functions of the character device, so kill both. Moving the compat_ioctl handling from common code into the driver itself fixes build problems when CONFIG_BLOCK is disabled.

* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

The busybox's init issues this ioctl to know vt-console or serial-console. If the console was serial console, VT ioctls are not handled by the serial driver.

* compat_ioctl: pass compat pointer directly to handlersArnd Bergmann2009-12-101-128/+83

* compat_ioctl: simplify lookup tableArnd Bergmann2009-12-101-46/+44
| | | | | | | | | | | | | | | | | | | | | | The compat_ioctl table now only contains entries for COMPATIBLE_IOCTL, so we only need to know if a number is listed in it or now. As an optimization, we hash the table entries with a reversible transformation to get a more uniform distribution over it, sort the table at startup and then guess the position in the table when an ioctl number gets called to do a linear search from there. With the current set of ioctl numbers and the chosen transformation function, we need an average of four steps to find if a number is in the set, all of the accesses within one or two cache lines. This at least as good as the previous hash table approach but saves 8.5 kb of kernel memory. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

* compat_ioctl: Remove BKLArnd Bergmann2009-12-101-2/+0
| | | | | | | | | | | | | | | | We have always called ioctl conversion handlers under the big kernel lock, although that is generally not necessary. In particular it is not needed for conversion of data structures and for calling sys_ioctl or do_vfs_ioctl, which will get the BKL again if needed. Handlers doing more than those two have been moved out, so we can kill off the BKL from compat_sys_ioctl. This may significantly improve latencies with 32 bit applications, and it avoids a common scenario where a thread acquires the BKL twice.

The driver treats this as a TUNSETIFF in native mode, but there is no way for the generic compat_ioctl() function to emulate this behaviour. Possibly the driver was only doing this accidentally anyway, but if any code relies on this misfeature, it now also works in compat mode.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1) Move the MEMREADOOB/MEMWRITEOOB compat_ioctl wrappers from fs/compat_ioctl.c into mtdchar.c . Original request was here: http://lkml.org/lkml/2009/4/1/295 2) Add missing COMPATIBLE_IOCTL lines, so that mtd-utils does not error out when running in 64/32 compatibility mode.

As these ioctls are 32/64-bit compatible two simple COMPATIBLE_IOCTL entries in fs/compat_ioctl.c will do the job.
