lzma-uncramfs v0.7rg - Feb 2011 by Valerio Di Giampietro (http://va.ler.io) ------------------------------------------------------------------------------ lzma-uncramfs is a modification of the uncramfs program to be able to unpack cramfs images included in some openrg based home routers. It includes lzma decompression and a different PAGE_CACHE_SIZE. To successfully compile lzma-uncramfs an old version of lzma modified by Jungo/OpenRG team is included. Uncramfs v0.7 ------------- Uncramfs is a simple program currently written in C (but I'm working on a more functional C++ version). Its only purpose in life is to unpack and list the files in a cramfs image. NB. this uncramfs includes unconditional support for the non-standard XIP (execute in place) feature, whereby executable files are stored uncompressed, so they will run directly from ROM (or flash). To activate this you have to chmod o+t <file> This feature is currently used by the Agenda Computing VR3 Linux PDA. It takes 2 command line arguments; the directory to unpack into, and the name of the cramfs image. If the the unpacking directory name is (or begins with) "-" then unpacking is turned off and you only get the listing. It will print some "Reassuring" info about the cramfs image, and the listing has been extensively reworked to look quite like the listing from ls. If the effective uid of the execuatble isn't root then it won't even attempt to create device nodes, or to set the correct owner and group on the extracted files. It currently doesn't handle unix sockets (but there aren't any in the stock VR3 images). For example: uncramfs unpack root-0.20.0.cramfs Will unpack the root-0.20.0.cramfs image into the unpack directory; uncramfs - root-0.20.0.cramfs Will just list the contents of the image. Uncramfs is copyright Andrew Stitcher and licensed under the terms of the GNU GPL version 2.

Had a killer bug in uncompresssing files that lost all the files blocks after the first! v0.3: Fix release from cam to remedy the killer bug v0.3.1: Release from cam which includes some of his scripts v0.4: [Not released to net] Ported original C++ code to C; Ported cam's bug fix (actually I had independently fixed the bug in my own codebase); Extensively reworked the listing to be as much like ls as possible; Set umask to 0 in uncramfs so the images modes are correctly respected; Don't try to do privileged things unless we are running as root; v0.5: [Released to net 6 June 2001] Added README Added some summary stats Can turn off the unpacking so we just get the listing (and summary) All summary info is in  brackets for easy stripping v0.6: [Released on wiki site, 8 June 2001] Context added to notes Fixed bug whereby suid information was reset on chown, leaving suid files without suid permission. Credit to Luis Maria Cruz Vazquez for assistance in nailing this bug. -Cam v0.7: [Released on wiki site, 24 Oct 2001] Patched by Lev Serebryakov to allow non superuser to unpack safely. Also includes mapping of UID and GID. -Cam
