Update the versioning information. Make the message types generic. Add an
outgoing message queue to the daemon struct. Make the functions to parse
and write the packet lengths available to the rest of the module. Add
functions to create and destroy the daemon structs. Clean up some of the
comments and make the code a little more consistent with itself.

A regular device file was my real preference from the get-go, but I went with
netlink at the time because I thought it would be less complex for managing
send queues (i.e., just do a unicast and move on). It turns out that we do
not really get that much complexity reduction with netlink, and netlink is
more heavyweight than a device handle.
In addition, the netlink interface to eCryptfs has been broken since 2.6.24.
I am assuming this is a bug in how eCryptfs uses netlink, since the other
in-kernel users of netlink do not seem to be having any problems. I have had
one report of a user successfully using eCryptfs with netlink on 2.6.24, but
for my own systems, when starting the userspace daemon, the initial helo
message sent to the eCryptfs kernel module results in an oops right off the
bat. I spent some time looking at it, but I have not yet found the cause.
The netlink interface breaking gave me the motivation to just finish my patch
to migrate to a regular device handle. If I cannot find out soon why the
netlink interface in eCryptfs broke, I am likely to just send a patch to
disable it in 2.6.24 and 2.6.25. I would like the device handle to be the
preferred means of communicating with the userspace daemon from 2.6.26 on
forward.
This patch:
Functions to facilitate reading and writing to the eCryptfs miscellaneous
device handle. This will replace the netlink interface as the preferred
mechanism for communicating with the userspace eCryptfs daemon.
Each user has his own daemon, which registers itself by opening the eCryptfs
device handle. Only one daemon per euid may be registered at any given time.
The eCryptfs module sends a message to a daemon by adding its message to the
daemon's outgoing message queue. The daemon reads the device handle to get
the oldest message off the queue.
Incoming messages from the userspace daemon are immediately handled. If the
message is a response, then the corresponding process that is blocked waiting
for the response is awakened.

A command that causes a line feed while a background color is active,
such as
perl -e 'print "x" x 60, "\e[44m", "x" x 40, "\e[0m\n"'
and
perl -e 'print "x" x 40, "\e[44m\n", "x" x 40, "\e[0m\n"'
causes the line that was started as a result of the line feed to be completely
filled with the currently active background color instead of the default
color.
When scrolling, part of the current screen is memcpy'd/memmove'd to the new
region, and the new line(s) that will appear as a result are cleared using
memset. However, the lines are cleared with vc->vc_video_erase_char, causing
them to be colored with the currently active background color. This is
different from X11 terminal emulators which always paint the new lines with
the default background color (e.g. `xterm -bg black`).
The clear operation (\e[1J and \e[2J) also use vc_video_erase_char, so a new
vc->vc_scrl_erase_char is introduced with contains the erase character used
for scrolling, which is built from vc->vc_def_color instead of vc->vc_color.

Instead of using the malloc() and free() wrappers needed by the
lib/inflate.c code for allocations, simply use kmalloc() and kfree() in the
initramfs code. This is needed for a further lib/inflate.c-related cleanup
patch that will remove the malloc() and free() functions.
Take that opportunity to remove the useless kmalloc() return value
cast.

This version brings a few fixes for the extern checks, and a couple of
new checks.
Of note:
- false is now recognised as a 0 assignment in static/external
assignments,
- printf format strings including %L are reported,
- a number of fixes for the extern in .c file detector which had
temporarily lost its ability to detect variables; undetected due to
the loss of its test.
Andy Whitcroft (8):
Version: 0.18
false should trip 0 assignment checks
tests: reinstate missing tests
tests: allow specification of the file extension for a test
fix extern checks for variables
check for and report %Lu, %Ld, and %Li
ensure we only start a statement on lines with some content

This version brings improvements to external declaration detection, fixes to
quote tracking, fixes to unary tracking, some clarification of wording, and
the usual slew of fixes for false positives.
Of note:
- much better unary tracking across preprocessor directives
- UTF8 checks highlight the character at fault
- widening of mutex detection
Andy Whitcroft (17):
Version: 0.17
values: __attribute__ carries through the previous type
quotes: should only follow "positive" lines
clarify the indent tabs over spaces wording
loosen NR_CPUS check for array range initialisers
detect external function declarations without an extern prefix
function declaration arguments should be with the identifier
DEFINE_MUTEX should report in line with struct mutex
NR_CPUS is valid in preprocessor statements
comment detection should not start on the @@ line
types: add support for #undef
tighten mutex/completion reports to usage
allow export of function pointers
values: preprocessor #define is out of line maintain values
values: #define does not always have parentheses
unary '*' may be const
utf8 checks should report location of the invalid character

This can be triggered with root help only, but...
Register the ":text:E::txt::/root/cat.txt:' rule in binfmt_misc (by root) and
try launching the cat.txt file (by anyone) :) The result is - the endless
recursion in the load_misc_binary -> open_exec -> load_misc_binary chain and
stack overflow.
There's a similar problem with binfmt_script, and there's a sh_bang memner on
linux_binprm structure to handle this, but simply raising this in binfmt_misc
may break some setups when the interpreter of some misc binaries is a script.
So the proposal is to turn sh_bang into a bit, add a new one (the misc_bang)
and raise it in load_misc_binary. After this, even if we set up the misc ->
script -> misc loop for binfmts one of them will step on its own bang and
exit.

SysRQ-P is not always useful on SMP systems, since it usually ends up showing
the backtrace of a CPU that is doing just fine, instead of the backtrace of
the CPU that is having problems.
This patch adds SysRQ show-all-cpus(L), which shows the backtrace of every
active CPU in the system. It skips idle CPUs because some SMP systems are
just too large and we already know what the backtrace of the idle task looks
like.

I noticed that 2.6.24.2 calculates bprm->argv_len at do_execve(). But it
doesn't update bprm->argv_len after "remove_arg_zero() +
copy_strings_kernel()" at load_script() etc.
audit_bprm() is called from search_binary_handler() and
search_binary_handler() is called from load_script() etc. Thus, I think the
condition check
if (bprm->argv_len > (audit_argv_kb << 10))
return -E2BIG;
in audit_bprm() might return wrong result when strlen(removed_arg) !=
strlen(spliced_args). Why not update bprm->argv_len at load_script() etc. ?
By the way, 2.6.25-rc3 seems to not doing the condition check. Is the field
bprm->argv_len no longer needed?

Almost all implementations of pci_iomap() in the kernel, including the generic
lib/iomap.c one, copies the content of a struct resource into unsigned long's
which will break on 32 bits platforms with 64 bits resources.
This fixes all definitions of pci_iomap() to use resource_size_t. I also
"fixed" the 64bits arch for consistency.

print_fn_descriptor_symbol() prints the address if we don't have a symbol, so
no need to print both.
Also, combine printing return value with elapsed time. Changes this:
Calling initcall 0xc05b7a70: pci_mmcfg_late_insert_resources+0x0/0x50()
initcall 0xc05b7a70: pci_mmcfg_late_insert_resources+0x0/0x50() returned 1.
initcall 0xc05b7a70 ran for 0 msecs: pci_mmcfg_late_insert_resources+0x0/0x50()
initcall at 0xc05b7a70: pci_mmcfg_late_insert_resources+0x0/0x50(): returned with error code 1
to this:
calling pci_mmcfg_late_insert_resources+0x0/0x50()
initcall pci_mmcfg_late_insert_resources+0x0/0x50() returned 1 after 0 msecs
