Remove RPM spec file
Building packages for distributions is typically something highly
distribution specific. While there are widely used package formats
like RPM, implementing a de-facto standard, the build process,
list of files actually packaged, list of required dependencies,
package grouping, package versioning, etc... is still _very_
distribution specific. In fact, this spec file completely fails to
address some of these points.
Actual RPM based distributions out there currently use their own,
distribution specific, RPM spec files that were possibly _based_ on
this one at some point (judging from similar descriptions).
The spec file _may_ have worked at some point, but it definitely doesn't
work with the new build system and there is no real reason to fix it
(which, by definition, isn't possible for the reasons above) and drag it
along for another decade or two.

Remove unused and broken mtd_write_img function from libmtd
The function _tries_ to support short reads but doesn't adjust the
pointer into the buffer. If a short read happens, we scrambles the
flash contents. Interrupted reads aren't handled. Short or
interrupted writes aren't handled at all. Either a write succeeds
writing the entire buffer or the function gives up.

This fix was initialially part of a patch submitted by Carsten Schlote

issues and a proposed buffer size change guessed by shotgun debugging.
I was unable to reproduce the claimed segfaults in the compression
function that lead to the proposed buffer size change. Valgrind did
not issue any errors or warnings about the code in question either,
so I didn't include the proposed buffer size change.
The original patch also added a call to lzo_init(), which (according
to LZO documentation & source code) does not actually perform any
initialization, but only checks at runtime that the data type sizes and
endianness of the library code match those in the caller code and
should be unnecessary.

mkfs.ubifs: Optionally create extended attribute with inode number
This is done to allow creating images suitable for IMA directory
appraisal. IMA creates a hash for directories and attaches this
hash to the directory itself as an extended attribute. Among other
things the inode numbers of the files are hashed. So, to create
a valid hash in the UBIFS image the evmctl tool needs to know
the inode numbers which the files in the UBIFS image will have.
evmctl will read the inode numbers from the user.image-inode-number
extended attribute. Since extended attributes are inodes themselves
the inode numbers for the generated image will change when the
extended attributes change, so to generate a correctly hashed
UBIFS image, both evmctl and mkfs.ubifs must be run twice:
1) execute evmctl to iterate over the directory tree. This will
create the security.ima and security.evm extended attributes.
The existence of the attributes makes sure that subsequent
calls to mkfs.ubifs will use the same inode numbers. evmctl
will use the inode numbers from the host filesystem in this
step which makes the resulting image unusable
2) execute mkfs.ubifs -a. This will create the user.image-inode-number
extended attributes on files/directories added to the image.
3) execture evmctl again. This time evmctl will pick the inode
numbers from the user.image-inode-number extended attribute
instead of the ones from the host filesystem
4) execute mkfs.ubifs again. This will create the correct image.
The now existing user.image-inode-number extended attributes
are ignored and not added to the image.

autogenerated dependency files are not being utilized properly
TL;DR Acked-by: Mike Frysinger <vapier@gentoo.org>
=====
Auto-generated dependency rules are not being written correctly, so
changes to dependent files (e.g., headers) do not actually trigger
rebuilds.
The problem
===========
It appears that when a dependency generation flag is passed directly to
the preprocessor (with '-Wp,...'), it loses information about the output
path. So, it just makes up the output name as $(basename).o, with no
path information. This yields .*.c.dep files that look like this:
This is the case for both in-tree *and* out-of-tree builds. Naturally,
this is a problem for out-of-tree builds. But it is also a problem for
in-tree builds, because we use rules like this for builds:
$(BUILDDIR)/%.o: %.c
and make doesn't recognize $(BUILDDIR)/%.o as the same as %.o even when
$(BUILDDIR) == $(PWD).
Example failures
================
## Rebuilding after touching common header doesn't recompile anything
$ make
(...)
$ touch include/libmtd.h
$ make
CHK include/version.h
## Same for out-of-tree builds
$ BUILDDIR=test make
(...)
$ touch include/libmtd.h
$ BUILDDIR=test make
CHK include/version.h
I noticed this when seeing that flash_lock would not get rebuilt when
modifying flash_unlock.c (where 99% of the source code lies):
$ make
(...)
$ touch flash_unlock.c
$ make
CHK include/version.h
CC flash_unlock.o
LD flash_unlock
The fix
=======
Just pass -MD straight to the compiler, and make sure to specify the
output file for the dependency info with -MF.

libmtd: don't ignore "region index" parameter in mtd_regioninfo()
ioctl(MEMGETREGIONINFO) has one input parameter (regionindex) and three

in mtdinfo/libmtd here:
1. mtdinfo.c doesn't initialize its region_info_user struct, instead
passing uninitialized data to mtd_regioninfo()
2. mtd_regioninfo() fails to utilize the 'regidx' parameter to fill out
the regionindex parameter properly, so the garbage from mtdinfo.c is
propagated to the ioctl()
This means that mtdinfo will continuously probe the same (possibly
out-of-range) erase region, instead of looping over the valid regions.
Let's fix this in the mtd_regioninfo() helper, and at the same time,
let's zero out the mtdinfo.c buffer, as an additional precaution to keep

1. erase block
2. write data
3. read and verify (N times)
This seem to apply more pressure on a NAND driver's ECC engine and has been
used to discover stability problems with an old OMAP2.
include/common.h: fix build against recent 0.9.33 uClibc
An implementation of rpmatch() was backported to the 0.9.33 branch of uClibc.
So the uClibc version check introduced in commit 50c9e11f7e (include/common.h:
fix build against current uClibc) is not enough. Rename the local rpmatch()
implementation to avoid collision.

include/common.h: fix build against current uClibc
Commit dbe0fd17f2 (mtd-utils: new prompt() helper for talking to the user)
introduced a rpmatch() call. However, uClibc versions older than (not yet
released) 0.9.34 don't have rpmatch() implementation. Add one.

make_a_release.sh: suggest announcement e-mail
The 'make_a_release.sh' script appears to be extremely useful - I do not
forget things as I used to anymore (amending Makefile, signing, uploading
to the FTP server, etc). It is very useful that it suggest me exact commands
which I may just copy-past to my command line.
This patch improves the script and makes it suggest the e-mail announcement
which I may just copy-paste to my command line and the announcement will
be sent using 'git send-email' command. It will include all the interested
parties in CC.

ubiformat: correct "non-ubifs" warning message
UBI's raw flash scan actually scans for UBI data, not UBIFS data (there
*are* UBI users that are not UBIFS!), so correct the warning message.
This also matches the comment in libscan.h.

mtd-utils: Makefile: add LDFLAGS_mkfs.ubifs
The build rule for mkfs.ubifs was missing an LDFLAGS_* variable like
mkfs.jffs2 had. This prevented mkfs.ubifs from being built against
explicit external libraries which is needed when cross-compiling.
This also adds UUIDCPPFLAGS and UUIDLDFLAGS variables to support the
mkfs.ubifs build.

check the MLC nand type
In the current code, the MTD_NANDFLASH stands for both the SLC and MLC.
In the kernel, the MTD_NANDFLASH only stands for the SLC now,
so in order to keep the logic unchanged, we should also check the MLC
NAND by MTD_MLCNANDFLASH.

ubiupdatevol: add a --skip option
This already has a --size option for controlling how many bytes to read
from the input. Add a --skip option to control the offset into the input
too. This way people don't have to do `dd | ubiupdatevol`.
While we're here, I've fixed the types used with args.size and the read
loop so that they can hold the right sizes (like setting a 32bit+ size).

nandwrite: add --input-{skip,size} options
If you have a file image and want to copy sub-portions out and into
NAND, there's no easy way to do that. You can use dd to extract it
to a temp file, or pipe it to nandwrite 1 page at a time. Both suck.
Add two new flags to explicitly set the size and offset of the input
file. Seeking stdin isn't currently supported as I'm not sure it's
necessary. It wouldn't be hard to add though...

nandwrite: clean up length types
We use 'int' in many places to represent offsets/sizes. That obviously
does not play well with larger NAND devices on 32bit systems. Instead,
use the right type as needed:
- long long to represent the length of the image
- use fstat() rather than lseek();lseek(); to get the length of the image
- use size_t/ssize_t when working with read()
- tweak the printf formats as needed

move _GNU_SOURCE to the main makefile
A bunch of utils are relying on _GNU_SOURCE already. The new prompt code
uses getline() which is now part of POSIX, but in older versions of glibc,
it was behind _GNU_SOURCE as it was a GNU extension.
This change doesn't actually tie us to glibc. Only code that uses GNU
extensions does that. It just kills warning when using older versions of
glibc.
