Several people have observed that perhaps LOG_BUF_SHIFT should be in a more
obvious place than under DEBUG_KERNEL. Under some circumstances (such as the
PARISC architecture), DEBUG_KERNEL can increase kernel size, which is an
undesirable trade off for something as trivial as increasing the kernel log
buffer size.

Instead, move LOG_BUF_SHIFT into "General Setup", so that people are more
likely to be able to change it such a circumstance that the default buffer
size is insufficient.

flush_scheduled_work() can sleep, and we're calling it under spinlock.

AFAICS, moving flush_scheduled_work before spin_lock() should not cause any
problems.

Reason being - The only thing that can race against tpm_release is tpm_open
(tpm_release is called when last reference to the file is closed and only
thing that can happen after that is tpm_open??) and tpm_open acquires
driver_lock and more over it bails out with EBUSY if chip->num_opens is
greater than 0.

I also moved chip->num_pending-- to after deleting timer and setting data
pending as it looks more correct for the paranoid although it probably doesn't
matter as it is guarded by driver_lock.  None the less this change should not
cause problems.

While I was at it I noticed a missing NULL check in tpm_register_hardware
which is fixed with this patch as well.

The UTF-8 part of the vt driver suffers from the following issues which are
addressed in my patch:

1) If there's no glyph found for a particular valid UTF-8 character, we try
   to display U+FFFD. However if this one is not found either, here's what
   the current kernel does:

   - First, if the Unicode value is less than the number of glyphs, use the
     glyph directly from that position of the glyph table. While it may be a
     good idea in the 8-bit world, it has absolutely no sense with Unicode
     in mind. For example, if a Latin-2 font is loaded and an application
     prints U+00FB ("u with circumflex", not present in Latin-2) then as a
     fallback solution the glyph from the 0xFB position of the Latin-2
     fontset (which is an "u with double accent" - a different character) is
     displayed.

   - Second, if this fallback fails too, a simple ASCII question mark is
     printed, which is visually undistinguishable from a real question mark.

   I changed the code to skip the first step (except if in non-UTF-8 mode),
   and changed the second step to print the question mark with inverse color
   attributes, so it is visually clear that it's not a real question mark,
   and resembles more to the common glyph of U+FFFD.

2) The UTF-8 decoder is buggy in many ways:

   - Lone continuation bytes (section 3.1 of Markus Kuhn's UTF-8 stress
     test) are not caught, they are displayed as some "random" (taken
     directly form the font table, see above) glyphs instead the replacement
     character.

   - Incomplete sequences (sections 3.2 and 3.3 of the stress test) emit no
     replacement character, but rather cause the subsequent valid character
     to be displayed more times(!).

   - The decoder is not safe: overlong sequences are not caught currently,
     they are displayed as if these were valid representations. This may
     even have security impacts.

   - The decoder does not handle D800..DFFF and FFFE..FFFF specially, it
     just emits these code points and lets it be looked up in the glyph
     table. Since these are invalid code points, I replace them by U+FFFD
     and hence give no chance for them to be looked up in the glyph table.
     (Assuming no font ships glyphs for these code points, this change is
     not visible to the users since the glyph shown will be the same.)

   With my fixes to the decoder it now behaves exactly as Markus Kuhn's
   stress test recommends.

3) It has no concept of double-width (CJK) characters. It's way beyond the
   scope of my patch to try to display them, but at least I think it's
   important for the cursor to jump two positions when printing such
   characters, since this is what applications (such as text editors)
   expect. Currently the cursor only jumps one position, and hence
   applications suffer from displaying and refreshing problems, and editing
   some English letters that are preceded by some CJK characters in the same
   line is a nightmare. With my patch an additional space is inserted after
   the CJK character has been printed (which usually means a replacement
   symbol of course). (If U+FFFD isn't availble and hence an inverse
   question mark is displayed in the first cell, I keep the inverted state
   for the space in the 2nd column so it's quite easy to see that they are
   tied together.)

4) There is a small built-in table of zero-width spaces that are not to be
   printed but silently skipped. U+200A is included there, but it's not a
   zero-width character, so I remove it from there.

A patch that stores inode flags such as S_IMMUTABLE, S_APPEND, etc.  from

thing is done on GETFLAGS ioctl.

Quota code changes these flags on quota files (to make it harder for
sysadmin to screw himself) and these changes were not correctly propagated
into the filesystem (especially, lsattr did not show them and users were
wondering...).

As discovered here today, the change in Kernel 2.6.17 intended to inhibit
users from setting RLIMIT_CPU to 0 (as that is equivalent to unlimited) by
"cheating" and setting it to 1 in such a case, does not make a difference,
as the check is done in the wrong place (too late), and only applies to the
profiling code.

On all systems I checked running kernels above 2.6.17, no matter what the
hard and soft CPU time limits were before, a user could escape them by
issuing in the shell (sh/bash/zsh) "ulimit -t 0", and then the user's
process was not ever killed.

Attached is a trivial patch to fix that.  Simply moving the check to a
slightly earlier location (specifically, before the line that actually
assigns the limit - *old_rlim = new_rlim), does the trick.

Do note that at least the zsh (but not ash, dash, or bash) shell has the
problem of "caching" the limits set by the ulimit command, so when running
zsh the fix will not immediately be evident - after entering "ulimit -t 0",
"ulimit -a" will show "-t: cpu time (seconds) 0", even though the actual
limit as returned by getrlimit(...) will be 1.  It can be verified by
opening a subshell (which will not have the values of the parent shell in
cache) and checking in it, or just by running a CPU intensive command like
"echo '65536^1048576' | bc" and verifying that it dumps core after one
second.

Regardless of whether that is a misfeature in the shell, perhaps it would
be better to return -EINVAL from setrlimit in such a case instead of
cheating and setting to 1, as that does not really reflect the actual state
of the process anymore.  I do not however know what the ground for that
decision was in the original 2.6.17 change, and whether there would be any
"backward" compatibility issues, so I preferred not to touch that right
now.

While the !highres/!dyntick code assigns the duty of the do_timer() call to
one specific CPU, this was dropped in the highres/dyntick part during
development.

Steven Rostedt discovered the xtime lock contention on highres/dyntick due
to several CPUs trying to update jiffies.

Add the single CPU assignement back.  In the dyntick case this needs to be
handled carefully, as the CPU which has the do_timer() duty must drop the
assignement and let it be grabbed by another CPU, which is active.
Otherwise the do_timer() calls would not happen during the long sleep.
