changelog

Solaris操作系统下的过滤驱动程序, C源码程序.

2003-01-29  Erez Zadok  <[e-mail]>

	* released version 0.0.6.1.

	* fistgen.h: on linux, $uid should translate to current->fsuid,
	and $gid should translate to current->fsgid.

2002-12-27  Erez Zadok  <[e-mail]>

	* released version 0.0.6.

	* configure.in: update to autoconf version 2.52 requirements, no
	longer using certain obsoleted features.

	* Makefile.am (dist-hook): don't distribute yacc/lex generated
	files.  Merge with previous dist-hook rule.

	* m4/HEADER: HEADER, TRAILER, host_macros.m4,
	package_bugreport.m4, package_name.m4, package_version.m4: new M4
	macros, copied from am-utils.

	* Makefile.am (EXTRA_DIST_M4): distribute new M4 macros.

	* bootstrap: expanded version of boot-strapping script.

	* wparse.y: missing ';' at end of cpp_conditional rule.

	* mkinstalldirs, depcomp, config.sub, config.guess, missing:
	update from latest GNU versions.

	* ALL: updated copyrights for 2003.

2002-07-03  Kiran-Kumar Muniswamy-Reddy  <[e-mail]>

	* fistgen.h (FIST_COPY_FROM_USER_4_IOCTL): freebsd : replaced
	'copyin' with 'bcopy'.
	(FIST_COPY_TO_USER_4_IOCTL): freebsd: replaced 'copyout' with
	'bcopy'.

	* fxns.c (expand_fistGetIoctlData): freebsd: data input from to an
	ioctl is already in kernel space and so can be accessed directly
	with a 'bcopy' instead of 'copyin'ing it and then accessing it.
	(expand_fistSetIoctlData): freebsd: data should be output from an
	ioctl into a kernel space address and not into a user space
	address.  so 'copyout' has been replaced by 'bcopy'.

2002-06-25  Kiran-Kumar Muniswamy-Reddy  <[e-mail]>

	* expand.c (expand_ubin_rules): check to see if the os is freebsd
	and if is, then generate $? in place of $^ - affects commands
	generated in Makefile for fist "user_src" declaration.

2002-04-03  Erez Zadok  <[e-mail]>

	* misc.c: remove basename() and dirname() code from here.

	* fparse.y, wparse.y: don't define yydebug unless needed

	* basename.c: replacement file for basename() function

	* dirname.c: replacement file for dirname() function

	* configure.in: check for basename() and dirname() and use
	replacement files for them if not found.

	* acconfig.h: define externs for dirname and basename only when needed.

	* Makefile.am (EXTRA_DIST_TEMPLATES): distribute additional files,
	esp. FreeBSD-4.5/4.6 templates, attach-mode files.

2002-03-30  Erez Zadok  <[e-mail]>

	* tests/base[0-2]fs.fist: finally, with fist-lite in place, we're
	able to take out temporary code for encoding/decoding data pages.

2002-03-25  Erez Zadok  <[e-mail]>

	* expand.c (expand_aux_src): include mmap.c code only if using
	filter data or filter sca.

	* fistgen.h: define default way to get inode numbers on 3
	platforms.

	* dollar_vars.c: support $0.inum in FiST language, to get the
	inode number out of a "vnode."  Code supports all 3 platforms, but
	only tested on Linux.

	* Makefile.am (EXTRA_DIST_FIST): ensure we distribute attach
	related files.

2002-03-24 Eric Cronin <[e-mail]>

	* expand.c (expand_aux_src): expand aux.c if need_aux_sources is
	on.

2002-03-24  Erez Zadok  <[e-mail]>

	* tests/*.fist: pass pagenum as new arg to {en,de}code_block
	functions.

	* validate.c (fist_validate_decl_dynamic_inode_numbers):
	validation function for dynamic_inode_numbers.

	* fistgen.h: add fla field to struct fist_globals.  extern decl
	for fist_validate_decl_dynamic_inode_numbers().

	* gen.c (generate_header): generate #define for
	FIST_DYNAMIC_INODE_NUMBERS automatically when declared or when
	using attach-mode.

	* fparse.y: parse dynamic_inode_numbers fist declaration.

2002-03-13  Ion Badulescu  <[e-mail]>

	* gzipfs/infblock.c: security fix for zlib

2002-03-08  Erez Zadok  <[e-mail]>

	* ALL: updated copyrights for 2002.

2002-02-21  Erez Zadok  <[e-mail]>

	* bootstrap: fail if one program fails, don't generate automatic
	depedency tracking code.

2002-02-17  Erez Zadok  <[e-mail]>

	* expand.c (expand_aux_src): add "attach.c" to compiled template
	sources, so we can put all attach-specific code in one place.

	* validate.c (fist_validate_decl_mntstyle): test for "mntstyle
	attach" new syntax keyword in .fist files.

	* gen.c (generate_header): generate FIST_MNTSTYLE_ATTACH flag as

	* AUTHORS: added Marc Boucher

2001-12-04  Ion Badulescu  <[e-mail]>

	* gzipfs/gzipfs.mk: we *cannot* use the same libz objects for both
	a kernel module and the userspace programs. use -lz instead.

	gzipfs/inffast.c, gzipfs/inflate.c, gzipfs/inftrees.c,
	gzipfs/infutil.c, gzipfs/trees.c, gzipfs/zutil.c: 

2001-11-30  Erez Zadok  <[e-mail]>

	* tasks: getfh support

2001-11-05  Erez Zadok  <[e-mail]>

	* tasks: updates: passing page number to encode/decode for
	computing IVs; u/mount-time actions (e.g., un/init a key list);
	updates for 2.2.20 + latest 2.4.x.

2001-10-27  Erez Zadok  <[e-mail]>

	* tasks: mention smbfs/rmdir support

2001-10-19  Ion Badulescu  <[e-mail]>

	* released version 0.0.5.2.

	* NEWS: updated notes for 0.0.5.2

	* tasks: minor updates

2001-10-18  Ion Badulescu  <[e-mail]>

	* cryptfs/cryptfs.fist: the BF cipher we are using is really a
	stream cipher, not a block cipher, so change encoding_type to
	stream.
	(cryptfs_encode_block): honor the length passed to us
	(cryptfs_decode_block): ditto

2001-10-17  Erez Zadok  <[e-mail]>

	* new FiST declaration: encoding_type (none|stream|block).  For
	setting the encoding/decoding type of the algorithm.  "none" for
	wrapfs; stream for a future rc4fs; block for cryptfs.

	* */*.fist: set correct encoding_blocksize (if needed) and
	encoding_type.

	* fistgen.h (MAX_ENCODING_BLOCKSIZE): set allowed max size for
	encoding_blocksize declaration.
	(struct fist_globals): add new field to store encoding_blocksize.
	Declare extern for encoding_blocksize validation function.

	* fparse.y: parse new encoding_blocksize declaration.

	* gen.c (generate_header): generate #define FIST_ENCODING_BLOCKSIZE
	definition in fistgen-generated header file.

	* main.c (fist_init): set default encoding_blocksize global
	variable to 1.

	* validate.c (fist_validate_decl_encoding_blocksize): validate
	values given to encoding_blocksize declaration.

	* NEWS: detail explanation of new encoding_blocksize declaration.

	* cryptfs/cryptfs.fist: set encoding_blocksize to 8, because
	Cryptfs's smallest encoding/decoding unit is 8 bytes.  This is
	because we are using the Blowfish block cipher.

	* tests/wrapfs.fist: set encoding_blocksize to 1, even though it's
	the default.

	* tests/rot13fs.fist: add comment about encoding_blocksize.

	* tasks: remove work that was done. add stuff to do.

	* configure.in: up to version 0.0.5.2.

	* cryptfs/fist_getiv.c: include stdlib.h for exit(3)

2001-09-29  Erez Zadok  <[e-mail]>

	* cryptfs/cryptfs.fist (cryptfs_encode_filename): initialize
	rounded_length to avoid gcc "may be used uninitialized" error
	(which isn't quite correct)

	* patches/fist-2.2.19.diff: CORRECT patch for 2.2.19 (previous one
	was from some post-2.2.18 kernel that wasn't quite 2.2.19)

	* BUGS: mention that we don't support Direct-IO yet (2.4.10 and
	newer).

	* patches/README: NO PATCHES FOR LINUX 2.4.X ARE NEEDED!

	* cryptfs/fist_setkey.c: include string.h and stdlib.h

	* cryptfs/cryptfs.fist (cryptfs_encode_filename): initialize
	crypted_name to NULL

	a copy_to_user/copy_from_user is zero, not the number of bytes
	copied.
