| * Documentation: add new description of path-name lookup.Neil Brown2015-11-022-1/+1298
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This document is based on three recent lwn.net articles. Some of the introductory material and linkage between articles has been removed, and some time-based descriptions have been revised. Also all links to code have been removed as the code is very close by. Contains corrections and improvements from Randy Dunlap <rdunlap@infradead.org>.

| | | | | | | | | | | | | | | | | | The kernel NMI watchdog acts as both a hardlockup and softlockup detector. However, the kernel parameter nmi_watchdog can only enable or disable the hardlockup detector. Clarify that in the documentation.

Removed pointer to different regional servers since oftc already uses geo-IP load balancing. The "description" quoted from the website no longer exists, therefore removed the reference, quotes and carets. The paragraph also contains a pointer to the kernelnewbies.org website.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the encoding of documents generated by DocBook depends on the current locale. Make the output reproducible independently of the locale, by setting the encoding to UTF-8 (LC_CTYPE=C.UTF-8) by preference, or ASCII (LC_CTYPE=C) as a fallback. LC_CTYPE can normally be overridden by LC_ALL, but the top-level Makefile unsets that.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The gpiolib supports parsing DT properties of the form <function>-gpio but it was only added for compatibility with older DT bindings that got it wrong and should not be used in newer bindings. The commit that added support for this was: dd34c37aa3e8 ("gpio: of: Allow -gpio suffix for property names") but didn't update the documentation to explain this so it's been a source of confusion.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "highlight" code is very sensible to the order of the hash keys, but the order of the keys cannot be predicted. It generates faulty DocBook entries like: - @<function>device_for_each_child</function> Sorting the result is not enough some times (as it's deterministic but we can't control it). We should use an array for that job, so we can guarantee that the order of the regex execution on dohighlight is correct.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Docproc processes the EXPORT_SYMBOL(f1) macro and uses -nofunc f1 to avoid duplicated documentation in the next call. It works for most of the cases, but there are some specific situations where a struct has the same name of an already-exported function. Current kernel-doc behavior ignores those structs and does not add them to the final documentation. This patch fixes it. This is unusual, the only case I've found is the drm_modeset_lock (function and struct) defined in drm_modeset_lock.h and drm_modeset_lock.c. Considering this, it should only affect the DRM documentation by including struct drm_modeset_lock to the final Docbook.

Call as: scripts/extract-module-sig.pl -[0adnks] module-file >out where the initial flag indicates which bit of the signed file you want dumping to stdout: (*) "-0". Dumps the unsigned data with the signature stripped. (*) "-a". Dumps all of the signature data, including the magic number. (*) "-d".

(*) "-n". Dumps the signer's name contents. (*) "-k". Dumps the key identifier contents. (*) "-s". Dumps the cryptographic signature contents. In the case that the signature is a PKCS#7 (or CMS) message, -n and -k will print a warning to stderr and dump nothing to stdout, but will otherwise complete okay; the entire PKCS#7/CMS message will be dumped by "-s"; and "-d" will show "0 0 2 0 0 <pkcs#7-msg-len>".

| | * | | | selinux: Use a kmem_cache for allocation struct file_security_structSangwoo2015-10-211-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The size of struct file_security_struct is 16byte at my setup. But, the real allocation size for per each file_security_struct is 64bytes in my setup that kmalloc min size is 64bytes because ARCH_DMA_MINALIGN is 64. This allocation is called every times at file allocation(alloc_file()). So, the total slack memory size(allocated size - request size) is increased exponentially. E.g) Min Kmalloc Size : 64bytes, Unit : bytes Allocated Size | Request Size | Slack Size | Allocation Count --------------------------------------------------------------- 770048 | 192512 | 577536 | 12032 At the result, this change reduce memory usage 42bytes per each file_security_struct Signed-off-by: Sangwoo <sangwoo2.park@lge.com> Acked-by: Stephen Smalley <sds@tycho.nsa.gov> [PM: removed extra subject prefix] Signed-off-by: Paul Moore <pmoore@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sprintf returns the number of characters printed (excluding '\0'), so we can use that and avoid duplicating the length computation.
