Fix logical bug in the bzip2 reading code, which results in bogus EIO

2007-12-18T01:50:49Z

returned on a perfectly valid bzip2 stream whose decompressed size is multiple of read-ahead buffer size. Reproduce the problem is easy: create some power-of-two sized file (truncate -s 1m file will do), bzip2 it and try to load it as md_image from loader. See how it fails. The bug doesn't affect gzip code (which most of bzip2-reading code was copied from) probably due to the fact that libgzip doesn't report Z_STREAM_END with the last block, but requires extra call to inflate() to retrieve it and has some extra data in the input stream at that time. However, apply similar fix to gzipfs.c just in the case the API will change in the future to do what bzip2 code does. Add some ifdef'ed code to enable testing bzipfs.c from witin normal FreeBSD environment as opposed to the restricted loader one, so that one can use gdb and whatnot.

Clean up error handling in libstand filesystem code to be more consistent:

2004-01-21T20:12:23Z

- bzipfs and gzipfs now properly return errno values directly from their read routines rather than returning -1. - missing errno values on error returns for the seek routines on almost all filesystems were added. - fstat() now returns -1 if an error occurs rather than ignoring it. - nfs's readdir() routine now reports valid errno values if an error or EOF occurs rather than EPERM (It was just returning 0 for success and 1 for failure). - nullfs used the wrong semantics for every function besides close() and seek(). Getting it right for close() appears to be an accident at that. - read() for buffered files no longer returns 0 (EOF) if an error occurs, but returns -1 instead.

Add splitfs vfs layer into libstand, which allows loading big kernels and

modules split across several physical medias. Following is how it works: The splitfs code, when asked to open "foo" looks for a file "foo.split" which is a text file containing a list of filenames and media names, e.g. foo.aa "Kernel floppy 1" foo.ab "Kernel floppy 2" foo.ac "Kernel and modules floppy" For each file segment, the process is: - try to open the file - prompt "Insert the disk labelled and press any key..." - try to open the file - return error if file could not be located RE team is free to use this feature in the upcoming 5.0-DP1.
