docs-rst: create an user's manual book

Place README, REPORTING-BUGS, SecurityBugs and kernel-parameters
on an user's manual book.

As we'll be numbering the user's manual, remove the manual
numbering from SecurityBugs.

-Bug hunting

-Last updated: 20 December 2005

-Introduction
-============
-
-Always try the latest kernel from kernel.org and build from source. If you are
-not confident in doing that please report the bug to your distribution vendor
-instead of to a kernel developer.
-
-Finding bugs is not always easy. Have a go though. If you can't find it don't
-give up. Report as much as you have found to the relevant maintainer. See
-MAINTAINERS for who that is for the subsystem you have worked on.
-
-Before you submit a bug report read
-:ref:`Documentation/REPORTING-BUGS <reportingbugs>`.
-
-Devices not appearing
-=====================
-
-Often this is caused by udev. Check that first before blaming it on the
-kernel.
-
-Finding patch that caused a bug
-===============================

-
-Finding using ``git-bisect``
-----------------------------
-
-Using the provided tools with ``git`` makes finding bugs easy provided the bug
-is reproducible.
-
-Steps to do it:
-
-- start using git for the kernel source
-- read the man page for ``git-bisect``
-- have fun
-
-Finding it the old way

-[Sat Mar  2 10:32:33 PST 1996 KERNEL_BUG-HOWTO lm@sgi.com (Larry McVoy)]
-
-This is how to track down a bug if you know nothing about kernel hacking.
-It's a brute force approach but it works pretty well.
-
-You need:
-
-        - A reproducible bug - it has to happen predictably (sorry)
-        - All the kernel tar files from a revision that worked to the
-          revision that doesn't
-
-You will then do:
-
-        - Rebuild a revision that you believe works, install, and verify that.
-        - Do a binary search over the kernels to figure out which one
-          introduced the bug.  I.e., suppose 1.3.28 didn't have the bug, but
-          you know that 1.3.69 does.  Pick a kernel in the middle and build
-          that, like 1.3.50.  Build & test; if it works, pick the mid point
-          between .50 and .69, else the mid point between .28 and .50.
-        - You'll narrow it down to the kernel that introduced the bug.  You
-          can probably do better than this but it gets tricky.
-
-        - Narrow it down to a subdirectory
-
-          - Copy kernel that works into "test".  Let's say that 3.62 works,
-            but 3.63 doesn't.  So you diff -r those two kernels and come
-            up with a list of directories that changed.  For each of those
-            directories:
-
-                Copy the non-working directory next to the working directory
-                as "dir.63".
-                One directory at time, try moving the working directory to
-                "dir.62" and mv dir.63 dir"time, try::
-
-                        mv dir dir.62
-                        mv dir.63 dir
-                        find dir -name '*.[oa]' -print | xargs rm -f
-
-                And then rebuild and retest.  Assuming that all related
-                changes were contained in the sub directory, this should
-                isolate the change to a directory.
-
-                Problems: changes in header files may have occurred; I've
-                found in my case that they were self explanatory - you may
-                or may not want to give up when that happens.
-
-        - Narrow it down to a file
-
-          - You can apply the same technique to each file in the directory,
-            hoping that the changes in that file are self contained.
-
-        - Narrow it down to a routine
-
-          - You can take the old file and the new file and manually create
-            a merged file that has::
-
-                #ifdef VER62
-                routine()
-                {
-                        ...
-                }
-                #else
-                routine()
-                {
-                        ...
-                }
-                #endif
-
-            And then walk through that file, one routine at a time and
-            prefix it with::
-
-                #define VER62
-                /* both routines here */
-                #undef VER62
-
-            Then recompile, retest, move the ifdefs until you find the one
-            that makes the difference.
-
-Finally, you take all the info that you have, kernel revisions, bug
-description, the extent to which you have narrowed it down, and pass
-that off to whomever you believe is the maintainer of that section.
-A post to linux.dev.kernel isn't such a bad idea if you've done some
-work to narrow it down.
-
-If you get it down to a routine, you'll probably get a fix in 24 hours.
-
-My apologies to Linus and the other kernel hackers for describing this
-brute force approach, it's hardly what a kernel hacker would do.  However,
-it does work and it lets non-hackers help fix bugs.  And it is cool
-because Linux snapshots will let you do this - something that you can't
-do with vendor supplied releases.
-
-Fixing the bug
-==============
-
-Nobody is going to tell you how to fix bugs. Seriously. You need to work it
-out. But below are some hints on how to use the tools.
-
-To debug a kernel, use objdump and look for the hex offset from the crash
-output to find the valid line of code/assembler. Without debug symbols, you
-will see the assembler code for the routine shown, but if your kernel has
-debug symbols the C code will also be available. (Debug symbols can be enabled
-in the kernel hacking menu of the menu configuration.) For example::
-
-    objdump -r -S -l --disassemble net/dccp/ipv4.o
-
-.. note::
-
-   You need to be at the top level of the kernel tree for this to pick up
-   your C files.
-
-If you don't have access to the code you can also debug on some crash dumps
-e.g. crash dump output as shown by Dave Miller::
-
-     EIP is at ip_queue_xmit+0x14/0x4c0
-      ...
-     Code: 44 24 04 e8 6f 05 00 00 e9 e8 fe ff ff 8d 76 00 8d bc 27 00 00
-     00 00 55 57  56 53 81 ec bc 00 00 00 8b ac 24 d0 00 00 00 8b 5d 08
-     <8b> 83 3c 01 00 00 89 44  24 14 8b 45 28 85 c0 89 44 24 18 0f 85
-
-     Put the bytes into a "foo.s" file like this:
-
-            .text
-            .globl foo
-     foo:
-            .byte  .... /* bytes from Code: part of OOPS dump */
-
-     Compile it with "gcc -c -o foo.o foo.s" then look at the output of
-     "objdump --disassemble foo.o".
-
-     Output:
-
-     ip_queue_xmit:
-         push       %ebp
-         push       %edi
-         push       %esi
-         push       %ebx
-         sub        $0xbc, %esp
-         mov        0xd0(%esp), %ebp        ! %ebp = arg0 (skb)
-         mov        0x8(%ebp), %ebx         ! %ebx = skb->sk
-         mov        0x13c(%ebx), %eax       ! %eax = inet_sk(sk)->opt
-
-In addition, you can use GDB to figure out the exact file and line
-number of the OOPS from the ``vmlinux`` file. If you have
-``CONFIG_DEBUG_INFO`` enabled, you can simply copy the EIP value from the
-OOPS::
-
- EIP:    0060:[<c021e50e>]    Not tainted VLI
-
-And use GDB to translate that to human-readable form::
-
-  gdb vmlinux
-  (gdb) l *0xc021e50e
-
-If you don't have ``CONFIG_DEBUG_INFO`` enabled, you use the function
-offset from the OOPS::
-
- EIP is at vt_ioctl+0xda8/0x1482
-
-And recompile the kernel with ``CONFIG_DEBUG_INFO`` enabled::
-
-  make vmlinux
-  gdb vmlinux
-  (gdb) p vt_ioctl
-  (gdb) l *(0x<address of vt_ioctl> + 0xda8)
-
-or, as one command::
-
-  (gdb) l *(vt_ioctl + 0xda8)
-
-If you have a call trace, such as::
-
-     Call Trace:
-      [<ffffffff8802c8e9>] :jbd:log_wait_commit+0xa3/0xf5
-      [<ffffffff810482d9>] autoremove_wake_function+0x0/0x2e
-      [<ffffffff8802770b>] :jbd:journal_stop+0x1be/0x1ee
-      ...
-
-this shows the problem in the :jbd: module. You can load that module in gdb
-and list the relevant code::
-
-  gdb fs/jbd/jbd.ko
-  (gdb) p log_wait_commit
-  (gdb) l *(0x<address> + 0xa3)
-
-or::
-
-  (gdb) l *(log_wait_commit + 0xa3)
-
-
-Another very useful option of the Kernel Hacking section in menuconfig is
-Debug memory allocations. This will help you see whether data has been
-initialised and not set before use etc. To see the values that get assigned
-with this look at ``mm/slab.c`` and search for ``POISON_INUSE``. When using
-this an Oops will often show the poisoned data instead of zero which is the
-default.
-
-Once you have worked out a fix please submit it upstream. After all open
-source is about sharing what you do and don't you want to be recognised for
-your genius?
-
-Please do read :ref:`Documentation/SubmittingPatches <submittingpatches>`
-though to help your code get accepted.
