Engelshall; when generating a random ethernet address because one is not available, set the least significant bit of the first byte of the MAC address, since it is the first bit to be transmitted, and is therefore the multicast bit. 2003-07-25 Theodore Ts'o <ty...@mi...> * Release of E2fsprogs 1.34 2003-04-21 Theodore Ts'o <ty...@mi...> * Release of E2fsprogs 1.33 2003-04-21 Theodore Ts'o <ty...@mi...> * Makefile.in: Use DYLD_LIBRAY_PATH so that "make check" works on Darwin systems when building with shared libraries. 2003-04-12 Theodore Ts'o <ty...@mi...> * gen_uuid.c: Add #ifdef checks around #include <sys/ioctl.h> and <sys/socket.h>. 2003-04-03 Theodore Ts'o <ty...@mi...> * gen_uuid.c (get_random_bytes): Always xor in a stream of bytes from the system PRNG (i.e., random/srandom, seeded from the time, pid, and uid) in case /dev/random isn't doing the right thing on a particular system. It doesn't hurt, and it can help, in the case of a buggy /dev/random. 2003-03-14 Theodore Ts'o <ty...@mi...> * Makefile.in: Add support for Apple Darwin 2003-03-06 Theodore Tso <ty...@mi...> * uuid_types.h.in: Don't redefine types if other e2fsprogs *_types.h files have been included already. * Makefile.in (tst_uuid): Link against the static library instead of all of the object files, so that we automatically pick up -lsocket under Solaris. 2003-03-02 Theodore Ts'o <ty...@mi...> * Makefile.in, uuidP.h, uuid_types.h.in: Use uuid_types.h instead of ext2_types.h 2002-11-09 Theodore Ts'o <ty...@mi...> * Release of E2fsprogs 1.32 2002-11-08 Theodore Ts'o <ty...@mi...> * Release of E2fsprogs 1.31 2002-10-31 Theodore Ts'o <ty...@mi...> * Release of E2fsprogs 1.30 2002-10-31 Theodore Ts'o <ty...@mi...> * gen_uuid.c (get_random_bytes): Don't spin forever if read() returns EINTR or EAGAIN, so that when /dev/random is opened O_NONBLOCK, we don't end up spinning forever. 2001-09-24 Theodore Tso <ty...@mi...> * Release of E2fsprogs 1.29 2001-08-31 Theodore Tso <ty...@th...> * Release of E2fsprogs 1.28 2002-07-15 Theodore Ts'o <ty...@mi...> * parse.c (uuid_parse): Fix uuid parsing bug which didn't complain for certain types of invalid input text.

Add the appropriate ifdef's in uuid.h to make it be C++ friendly. 2001-09-02 Theodore Tso <ty...@th...> * Release of E2fsprogs 1.24a 2001-08-30 Theodore Tso <ty...@th...> * Release of E2fsprogs 1.24 2001-08-15 Theodore Tso <ty...@va...> * Release of E2fsprogs 1.23 2001-06-23 Theodore Tso <ty...@va...> * Release of E2fsprogs 1.22 2001-06-21 Theodore Tso <ty...@va...> * uuid.h: Add protection against multiple inclusion 2001-06-15 Theodore Tso <ty...@va...> * Release of E2fsprogs 1.21 2001-06-01 Theodore Tso <ty...@va...> * Makefile.in, uuidP.h: Move include/asm/types.h.in to lib/ext2fs/ext2_types.h.in. 2001-06-01 Theodore Tso <ty...@va...> * unpack.c, unparse.c, uuid_time.c: Update files to be under the LGPL (that somehow were missed when libuuid was converted to use the LGPL). Whoops. 2001-05-25 Theodore Tso <ty...@va...> * Release of E2fsprogs 1.20 2001-05-14 Theodore Tso <ty...@va...> * tst_uuid.c, uuid_time.c: Remove unneeded #include of ext2_fs.h 2001-05-12 Theodore Tso <ty...@va...> * libuuid.3.in, uuid_clear.3.in, uuid_compare.3.in, uuid_copy.3.in, uuid_generate.3.in, uuid_is_null.3.in, uuid_parse.3.in, uuid_time.3.in, uuid_unparse.3.in: Update URL location of e2fsprogs package. 2001-05-01 Theodore Tso <ty...@va...> * parse.c, compare.c: Include string.h to fix gcc -Wall complaints. * gen_uuid.c: Define _SVID_SOURCE to avoid gcc -Wall errors because some required structures wouldn't be otherwise defined. Fix a minor gcc -Wall nit in the declaration of get_random_fd(). 2001-01-12 Theodore Ts'o <ty...@va...> * uuid_time.c (main), tst_uuid.c (main): Fix gcc -Wall complaints. * uuid.h, copy.c (uuid_copy): Change arguments to make it clear which argument is the source and which is the destination. * gen_uuid.c (get_random_fd): Use gettimeofday to seed the PRNG, so we can take advantage of tv_usec to do (slightly) better at seeding it. 2000-07-13 <ty...@va...> * Release of E2fsprogs 1.19 2000-07-07 Theodore Ts'o <ty...@va...> * Makefile.in (uuid_time): Fix compilation rule so that uuid_time.o doesn't get bashed in order to build the command-line version of uuid_time. 2000-07-04 Theodore Ts'o <ty...@va...> * Makefile.in: Remove explicit link of -lc in the shared library. (It shouldn't be necessary, and is harmful in some cases). 2000-06-12 Theodore Ts'o <ty...@va...> * gen_uuid.c (get_random_bytes): Use O_NONBLOCK when trying to open /dev/random. Break out the /dev/random initialization code into a get_random_fd() function, and use that function in uuid_generate() to determine whether to use uuid_generate_random() or uuid_generate_time(). 2000-05-25 <ty...@sn...> * Makefile: Add hack dependency rule so that parallel makes work correctly. 2000-04-07 Theodore Ts'o <ty...@va...> * clear.c, compare.c, copy.c, gen_uuid.c, isnull.c, pack.c, parse.c, uuid.h, uuidP.h: Changed copyright to be the LGPL. Thu Apr 6 17:38:58 2000 Theodore Y. Ts'o <ty...@si...> * Makefile.in (uuid_time): Compile uuid_time in two steps (first create .o, then link it against the libraries) to work around bug in a.out linker. * dll/jump.funcs, dll/jump.import, dll/jump.params: Update a.out shared library control files to reflect new added files. 2000-04-03 Theodore Ts'o <ty...@va...> * gen_uuid.c (get_clock): Fix bug where the last timeval wasn't getting set, causing potentially duplicate UUID's to be generated. 2000-03-12 Theodore Ts'o <ty...@va...> * gen_uuid.c (get_random_bytes): Make more paranoid about misbehaving /dev/urandom. If we get a return of zero without an error more than 8 times in a row, we break out and return an error. Also, if /dev/urandom doesn't exist, try /dev/random. 2000-01-18 Theodore Ts'o <ty...@va...> * Makefile.in: Since LIBUUID can sometimes include "-lsocket" we need a separate DEPLIBUUID that can be used in Makefile's dependency rules. 1999-11-19 <ty...@va...> * Makefile.in (distclean): Remove TAGS and Makefile.in.old from the source directory. 1999-11-10 <ty...@va...> * Release of E2fsprogs 1.18 1999-10-26 <ty...@va...> * Release of E2fsprogs 1.17 1999-10-26 <ty...@va...> * uuid_time.c (variant_string): Declare to be static to avoid gcc warnings. * uuid.h: Add function prototypes for uuid_generate_random() and uuid_generate_time(). 1999-10-25 <ty...@va...> * gen_uuid_nt.c (uuid_generate): W2K strikes again! An incompatible interface change means we need to detect whether the code is running on an NT4 or NT5 system. 1999-10-22 <ty...@va...> * Release of E2fsprogs 1.16 1999-10-21 <ty...@va...> * uuid_generate.8.in: Update man page to use a more standard format (bold option flags and italicized variables), as suggested by Andreas Dilger (ad...@en...) 1999-09-24 <ty...@va...> * gen_uuid_nt.c: New file which creates a UUID under Windows NT. 1999-07-18 Theodore Ts'o <ty...@rs...> * Release of E2fsprogs 1.15 1999-05-17 <ty...@rs...> * gen_uuid.c (get_random_bytes): Use a while loop when reading from /dev/urandom so that if we get interrupted while reading the right thing happens. (uuid_generate_random): Add new function which uses the new UUID format which uses 122 random bits to form the 128-bit UUID. (uuid_generate): Rename the old uuid_generate to be uuid_generate_time, and create a new uuid_generate function which calls either uuid_generate_random or uuid_genereate_time depending on whether /dev/urandom is present. * uuid_generate.3.in: Update to reflect changesin uuid_generate and its two new variants. * tst_uuid.c: Updated to test new uuid_generate functions, and to reflect new semantics of uuid_compare. Added tests to make sure the UUID type and variant created by UUID generate is correct. * uuid_time.c (uuid_variant, uuid_type): Added new functions to return the UUID variant and type information. The debugging program now prints the UUID variant and type, and warns if the unparsed time information is likely to be incorrect. * uuid_parse.3.in, libuuid.3.in: Miscellaneous text cleanups. 1999-05-03 <ty...@rs...> * compare.c (uuid_compare): Change sense of uuid_compare so that its return values match that of memcpy and the uuid_compare() found in Paul Leach's internet-draft. 1999-03-11 Andreas Dilger <ad...@en...> * Created man pages for libuuid functions. 1999-01-09 Theodore Ts'o <ty...@rs...> * Release of E2fsprogs 1.14 1998-12-15 Theodore Ts'o <ty...@rs...> * Release of E2fsprogs 1.13 1998-12-04 Theodore Ts'o <ty...@rs...> * Makefile.in: Update version numbers of the UUID shared library, since we've added a new function (uuid_time()). * uuid_time.c: New file which returns the time field of a UUID. (Good for debugging purposes) 1998-07-09 Theodore Ts'o <ty...@rs...> * Release of E2fsprogs 1.12 1998-06-25 Theodore Ts'o <ty...@rs...> * tst_uuid.c (main): Fixed bogus declaration of the main's argv parameter. 1998-04-26 Theodore Ts'o <ty...@rs...> * uuidP.h: Use asm/types.h instead of linux/types.h to avoid a problem caused by glibc hack to prevent linux/types.h from being included. 1998-03-30 Theodore Ts'o <ty...@rs...> * Makefile.in: Change to use new installation directory variables convention. Fix uninstall rules to take $(DESTDIR) into account. Sun Mar 8 22:17:59 1998 Theodore Ts'o <ty...@rs...> * gen_uuid.c (get_node_id): Use char * instead of caddr_t, which doesn't always exist for glibc. Tue Oct 14 21:48:16 1997 Theodore Ts'o <ty...@rs...> * gen_uuid.c: Use clock_reg instead of clock, since clock conflicts with a header file declaration. Tue Jun 17 01:33:20 1997 Theodore Ts'o <ty...@rs...> * Release of E2fsprogs 1.11 Thu Apr 24 12:16:42 1997 Theodre Ts'o <ty...@lo...> * Release of E2fsprogs version 1.10 Thu Apr 17 12:23:38 1997 Theodore Ts'o <ty...@rs...> * Release of E2fsprogs version 1.09 Fri Apr 11 18:56:26 1997 Theodore Ts'o <ty...@rs...> * Release of E2fsprogs version 1.08 Wed Mar 12 13:32:05 1997 Theodore Y.

Wed Jan 1 23:51:09 1997 Theodore Ts'o <ty...@rs...> * unpack.c, pack.c: Include string.h, since we use memcpy(). Tue Dec 3 13:05:11 1996 Theodore Ts'o <ty...@rs...> * parse.c: Add #include of ctype.h and stdlib.h, to pull in the required prototypes. Fri Oct 11 17:15:10 1996 Theodore Ts'o <ty...@rs...> * Makefile.in (DLL_ADDRESS): Updated DLL address for libuuid.
