This integrates the XZ decompression code to the x86 pre-boot code. mkpiggy.c is updated to reserve about 32 KiB more buffer safety margin for kernel decompression. It is done unconditionally for all decompressors to keep the code simpler. The XZ decompressor needs around 30 KiB of heap, so the heap size is increased to 32 KiB on both x86-32 and x86-64. Documentation/x86/boot.txt is updated to list the XZ magic number. With the x86 BCJ filter in XZ, XZ-compressed x86 kernel tends to be a few percent smaller than the equivalent LZMA-compressed kernel. Signed-off-by:

This implements the API defined in <linux/decompress/generic.h> which is used for kernel, initramfs, and initrd decompression. This patch together with the first patch is enough for XZ-compressed initramfs and initrd; XZ-compressed kernel will need arch-specific changes. The buffering requirements described in decompress_unxz.c are stricter than with gzip, so the relevant changes should be done to the arch-specific code when adding support for XZ-compressed kernel. Similarly, the heap size in arch-specific pre-boot code may need to be increased (30 KiB is enough). The XZ decompressor needs memmove(), memeq() (memcmp() == 0), and memzero() (memset(ptr, 0, size)), which aren't available in all arch-specific pre-boot environments. I'm including simple versions in decompress_unxz.c, but a cleaner solution would naturally be nicer. Signed-off-by:

In userspace, the .lzma format has become mostly a legacy file format that got superseded by the .xz format. Similarly, LZMA Utils was superseded by XZ Utils. These patches add support for XZ decompression into the kernel. Most of the code is as is from XZ Embedded <http://tukaani.org/xz/embedded.html>. It was written for the Linux kernel but is usable in other projects too. Advantages of XZ over the current LZMA code in the kernel: - Nice API that can be used by other kernel modules; it's not limited to kernel, initramfs, and initrd decompression. - Integrity check support (CRC32) - BCJ filters improve compression of executable code on certain architectures. These together with LZMA2 can produce a few percent smaller kernel or Squashfs images than plain LZMA without making the decompression slower. This patch: Add the main decompression code (xz_dec), testing module (xz_dec_test), wrapper script (xz_wrap.sh) for the xz command line tool, and documentation. The xz_dec module is enough to have a usable XZ decompressor e.g. for Squashfs. Signed-off-by:

Callback-to-callback decompression mode is used for initrd (not initramfs). The LZO wrapper is broken for this use case for two reasons: - The argument validation is needlessly too strict by requiring that "posp" is non-NULL when "fill" is non-NULL. - The buffer handling code didn't work at all for this use case. I tested with LZO-compressed kernel, initramfs, initrd, and corrupt (truncated) initramfs and initrd images. Signed-off-by: -

The code assumes that the input is valid and not truncated. Add checks to avoid reading past the end of the input buffer. Change the type of "skip" from u8 to int to fix a possible integer overflow. Signed-off-by:

The return value of flush() is not checked in unlzo(). This means that the decompressor won't stop even if the caller doesn't want more data. This can happen e.g. with a corrupt LZO-compressed initramfs image. Signed-off-by:

Validate the newly decoded distance (rep0) in process_bit1(). This is to detect corrupt LZMA data quickly. The old code can run for long time producing garbage until it hits the end of the input. Signed-off-by:

The return value of wr->flush() is not checked in write_byte(). This means that the decompressor won't stop even if the caller doesn't want more data. This can happen e.g. with corrupt LZMA-compressed initramfs. Returning the error quickly allows the user to see the error message quicker. There is a similar missing check for wr.flush() near the end of unlzma(). Signed-off-by:

Return value of rc->fill() is checked in rc_read() and error() is called when needed, but then the code continues as if nothing had happened. rc_read() is a void function and it's on the top of performance critical call stacks, so propagating the error code via return values doesn't sound like the best fix. It seems better to check rc->buffer_size (which holds the return value of rc->fill()) in the main loop. It does nothing bad that the code runs a little with unknown data after a failed rc->fill(). This fixes an infinite loop in initramfs decompression if the LZMA-compressed initramfs image is corrupt. Signed-off-by:

Validation of header.pos calls error() but doesn't make the function return to indicate an error to the caller. Instead the decoding is attempted with invalid header.pos. This fixes it. Signed-off-by:

set_error_fn() has become a useless complication after c1e7c3ae ("bzip2/lzma/gzip: pre-boot malloc doesn't return NULL on failure") fixed the use of error() in malloc(). Only decompress_unlzma.c had some use for it and that was easy to change too. This also gets rid of the static function pointer "error", which should have been marked as __initdata. Signed-off-by:

Generate a unique inode numbers for any entries in the cram file system. For files which did not contain data's (device nodes, fifos and sockets) the offset of the directory entry inside the cramfs plus 1 will be used as inode number. The + 1 for the inode will it make possible to distinguish between a file which contains no data and files which has data, the later one has a inode value where the lower two bits are always 0. It also reimplements the behavior to set the size and the number of block to 0 for special file, which is the right value for empty files, devices, fifos and sockets As a little benefit it will be also more compatible which older mkcramfs, because it will never use the cramfs_inode->offset for creating a inode number for special files.

When hypervisor decides to decrease target balloon size while the balloon driver tries to lock pages hypervisor may respond with VMW_BALLOON_PPN_NOTNEEDED. Use this data and immediately stop reserving pages and wait for the next update cycle to fetch new target instead of continuing trying to lock pages until size of refused list grows above VMW_BALLOON_MAX_REFUSED (16) pages. As a result the driver stops bothering the hypervisor with its attempts to lock more pages that are not needed anymore. Most likely next order from hypervisor will be to reduce ballon size anyway. It is a small optimization. Signed-off-by:

This is a 1-wire/w1 DS2423 slave driver for reading the values from all 4 counters available DS2423 devices by using standard w1_slave file. In ds2423 the counters are tied to ram pages 12-15 in and each of those ram-pages. Each of these counter values (and asoociated ram page values) are represented as a own line in w1_slave file. Driver has been tested on mips and x86. usage example: cat /sys/bus/w1/devices/1d-00000009b964/w1_slave 00 02 00 00 00 00 00 00 00 6d 38 00 ff ff 00 00 fe ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff crc=YES c=2 00 02 00 00 00 00 00 00 00 e0 1f 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff crc=YES c=2 00 5a 0e 5f 18 00 00 00 00 0b 28 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff crc=YES c=408882778 00 05 00 00 00 00 00 00 00 8d 39 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff crc=YES c=5 Patch includes also the documentation.
