1
2 version 1.4
3 * NEWS: Record release date.
4
5 tests: exercise the segfault fix
6 * tests/helin-segv: New test.
7 * Makefile.am (TESTS): Add it.
8
9 gzip -d: do not clobber stack for valid input on x86_64
10 * unlzw.c (unlzw): Avoid integer overflow.
11 Aki Helin reported the segfault along with an input to trigger the bug.
12 * NEWS (Bug fixes): Mention it.
13
14 maint: avoid a minor "make syntax-check" failure
15 * .x-sc_file_system: Exempt NEWS, since it includes a literal
16 from an old diagnostic.
17
18 maint: remove unused file: README-alpha
19 * README-alpha: Remove unused file.
20
21 build: update gnulib submodule to latest
22
23 2010-01-11 Yuxi Zhang <YZhang@qnx.com>
24
25 gzip -d: use memcpy more often
26 * inflate.c (inflate_codes): Use memcpy (rather than slower
27 memcopy-like code) in more cases.
28
29 2010-01-11 Jim Meyering <meyering@redhat.com>
30
31 build: do not override gnulib-provided AM_CFLAGS options
32 Avoid a warning from automake:
33 lib/Makefile.am:24: AM_CFLAGS multiply defined in condition TRUE ...
34 lib/gnulib.mk:30: ... `AM_CFLAGS' previously defined here
35 lib/Makefile.am:20: `lib/gnulib.mk' included from here
36
37 * lib/Makefile.am (AM_CFLAGS): Append $(WARN_CFLAGS) and
38 $(WERROR_CFLAGS), i.e., use "+=", not "=".
39 This was introduced via 2009-12-17 commit 0341fc22,
40 "build: with --enable-gcc-warnings, use -Werror",
41 but fortunately is not a bug, because the definition
42 it would have overridden was always empty.
43
44 gzip -d would fail with a CRC error...
45 ...for some inputs, and some memcpy implementations. It is possible
46 that an offending input has to be compressed "from FAT filesystem
47 (MS-DOS, OS/2, NT)", since the sole reproducer no longer evokes a
48 CRC error when uncompressed and recompressed on a GNU/Linux system.
49 Also, using an unpatched reverse-memcpy-gzip on over 100,000 inputs
50 on a GNU/Linux system did not turn up another reproducer.
51 * inflate.c (inflate_codes): Don't call memcpy with overlapping regions.
52 Properly detect when source and destination overlap.
53 * tests/memcpy-abuse: New test, to trigger misbehavior.
54 * Makefile.am (TESTS): Add it.
55 * NEWS (Bug fixes): Mention it.

68
69 build: update gnulib submodule to latest
70
71 2010-01-03 Jim Meyering <meyering@redhat.com>
72
73 maint: record update-copyright options for this package
74 * cfg.mk: Next time, just run "make update-copyright".
75
76 2010-01-01 Jim Meyering <meyering@redhat.com>
77
78 maint: update all FSF copyright year lists to include 2010

80 git ls-files |grep -vE '^(\..*|COPYING|gnulib)$' |xargs \
81 env UPDATE_COPYRIGHT_USE_INTERVALS=1 build-aux/update-copyright
82
83 2009-12-31 Jim Meyering <meyering@redhat.com>
84
85 maint: newer gnulib; don't hard-code my GPG key ID
86 * cfg.mk (gpg_key_ID): Remove definition, now that maint.mk automates it.
87 * gnulib: Update to lastest.
88
89 2009-12-30 Jim Meyering <meyering@redhat.com>
90
91 build: update gnulib submodule to latest
92
93 maint: remove lots of obsolete #if...HAVE_* checks
94 Remove many always-true cpp tests like #ifdef HAVE_UNISTD_H,
95 #ifdef HAVE_FCNTL_H and #ifdef SSIZE_MAX.
96 * gzip.c: As above.
97 * gzip.h: Likewise.
98 * inflate.c: Likewise.
99 * tailor.h: Likewise.
100 * unlzw.c: Likewise.
101 * util.c: Likewise.
102 * zip.c: Likewise.
103
104 build: add a syntax-check
105 * cfg.mk (sc_prohibit_obsolete_HAVE_HEADER_H): New rule.
106
107 build: with --enable-gcc-warnings, use -Werror
108 * Makefile.am (AM_CFLAGS): Enable $(WERROR_CFLAGS).
109 * lib/Makefile.am (AM_CFLAGS): Enable both $(WARN_CFLAGS) and
110 $(WERROR_CFLAGS).
111
112 build: quiet warnings from util.c
113 * configure.ac (warnings): Add -Wno-overflow and -Wno-type-limits.
114
115 build: avoid warning about possibly-no-return functions
116 * gzip.h (read_error, write_error): Mark these functions as "no-return".

129
130 build: avoid warnings about unused macros
131 * unzip.c (LOCTIM): Comment out unused macro.
132 * deflate.c (EQUAL): Remove definition. Use "0" at sole point of use.
133
134 build: util.c: avoid warnings about add_envopt
135 * util.c (add_envopt): The parameter "env" was used for two conflicting
136 purposes. One use required a const char* parameter, while the other
137 was used as an argument to free, which must not be "const".
138 Rename the parameter and use a new local variable for the second role.
139
140 build: avoid many const-related warnings
141 * gzip.c: Add "const" to many variables, to avoid compiler warnings.

151 * bootstrap.conf (gnulib_modules): Add fdopendir.
152 * gzip.c (treat_dir): Don't depend on HAVE_FDOPENDIR.

155
156 build: enable many warnings
157 * configure.ac: Add support for --enable-gcc-warnings.

162 * bootstrap.conf (gnulib_modules): Unindent list.
163
164 maint: cfg.mk: remove factored-out ftp host/dir definitions
165 * cfg.mk (gnu_ftp_host-alpha, gnu_ftp_host-beta gnu_ftp_host-stable):
166 (gnu_rel_host, url_dir_list): Remove definitions. The defaults,
167 now provided by maint.mk, are the same.
168 * gnulib: Update for latest, including those maint.mk additions.
169
170 build: "make stable" emitted an invalid gnupload command
171 * cfg.mk (gnu_ftp_host-stable): Rename from gnu_ftp_host-major.

2 * Noteworthy changes in release 1.4 (2010-01-20) [stable]
3
4 ** Bug fixes
5
6 gzip -d could segfault and/or clobber the stack, possibly leading to
7 arbitrary code execution. This affects x86_64 but not 32-bit systems.
8 This fixes CVE-2010-0001.
9 For more details, see http://bugzilla.redhat.com/554418
10
11 gzip -d would fail with a CRC error for some valid inputs.
12 So far, the only valid input known to exhibit this failure was
13 compressed "from FAT filesystem (MS-DOS, OS/2, NT)". In addition,
14 to trigger the failure, your memcpy implementation must copy in
15 the "reverse" order.

7474 Examples:
75 1. Upload automake-1.8.2b.tar.gz and automake-1.8.2b.tar.bz2 to two sites:
76 gnupload --to sources.redhat.com:~ftp/pub/automake \\
77 --to alpha.gnu.org:automake \\
78 automake-1.8.2b.tar.gz automake-1.8.2b.tar.bz2
79
80 2. Same as above, but also create symbolic links to automake-latest.tar.*:
81 gnupload --to sources.redhat.com:~ftp/pub/automake \\
82 --to alpha.gnu.org:automake \\
75 1. Upload foobar-1.0.tar.gz to ftp.gnu.org:
76 gnupload --to ftp.gnu.org:foobar foobar-1.0.tar.gz
77
78 2. Upload foobar-1.0.tar.gz and foobar-1.0.tar.xz to ftp.gnu.org:
79 gnupload --to ftp.gnu.org:foobar foobar-1.0.tar.gz foobar-1.0.tar.xz
80
81 3. Same as above, and also create symbolic links to foobar-latest.tar.*:
82 gnupload --to ftp.gnu.org:foobar \\
8383 --symlink-regex \\
84 automake-1.8.2b.tar.gz automake-1.8.2b.tar.bz2
85
86 3. Symlink automake-1.8.2b.tar.gz to automake-latest.tar.gz and
87 automake-1.8.2b.tar.bz2 to automake-latest.tar.bz2 on both sites:
88
89 gnupload --to sources.redhat.com:~ftp/pub/automake \\
90 --to alpha.gnu.org:automake \\
91 --symlink automake-1.8.2b.tar.gz automake-latest.tar.gz \\
92 automake-1.8.2b.tar.bz2 automake-latest.tar.bz2
93
94 4. Delete automake-1.8.2a.tar.gz and .bz2, remove symlink
95 automake-latest.tar.gz and upload automake-1.8.2b.tar.gz:
96
97 gnupload --to sources.redhat.com:~ftp/pub/automake \\
98 --to alpha.gnu.org:automake \\
99 --delete automake-1.8.2a.tar.gz automake-1.8.2a.tar.bz2 \\
100 --rmsymlink automake-latest.tar.gz \\
101 -- \\
102 automake-1.8.2b.tar.gz automake-1.8.2b.tar.bz2
84 foobar-1.0.tar.gz foobar-1.0.tar.xz
85
86 4. Upload foobar-0.9.90.tar.gz to two sites:
87 gnupload --to alpha.gnu.org:foobar \\
88 --to sources.redhat.com:~ftp/pub/foobar \\
89 foobar-0.9.90.tar.gz
90
91 5. Delete oopsbar-0.9.91.tar.gz and upload foobar-0.9.91.tar.gz
92 (the -- terminates the list of files to delete):
93 gnupload --to alpha.gnu.org:foobar \\
94 --to sources.redhat.com:~ftp/pub/foobar \\
95 --delete oopsbar-0.9.91.tar.gz \\
96 -- foobar-0.9.91.tar.gz
97
98 gnupload uses the ncftpput program to do the transfers; if you don't
99 happen to have an ncftp package installed, the ncftpput-ftp script in
100 the build-aux/ directory of the gnulib package
101 (http://savannah.gnu.org/projects/gnulib) may serve as a replacement.

18 /* _GL_WARN_ON_USE(function, "literal string") issues a declaration
19 for FUNCTION which will then trigger a compiler warning containing
20 the text of "literal string" anywhere that function is called, if
21 supported by the compiler. If the compiler does not support this
22 feature, the macro expands to an unused extern declaration.
23
24 This macro is useful for marking a function as a potential
25 portability trap, with the intent that "literal string" include
26 instructions on the replacement function that should be used
27 instead. However, one of the reasons that a function is a
28 portability trap is if it has the wrong signature. Declaring
29 FUNCTION with a different signature in C is a compilation error, so
30 this macro must use the same type as any existing declaration so
31 that programs that avoid the problematic FUNCTION do not fail to
32 compile merely because they included a header that poisoned the
33 function. But this implies that _GL_WARN_ON_USE is only safe to
34 use if FUNCTION is known to already have a declaration. Use of
35 this macro implies that there must not be any other macro hiding
36 the declaration of FUNCTION; but undefining FUNCTION first is part
37 of the poisoning process anyway (although for symbols that are
38 provided only via a macro, the result is a compilation error rather
39 than a warning containing "literal string"). Also note that in
40 C++, it is only safe to use if FUNCTION has no overloads.
41
42 For an example, it is possible to poison 'getline' by:
43 - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],
44 [getline]) in configure.ac, which potentially defines
45 HAVE_RAW_DECL_GETLINE
46 - adding this code to a header that wraps the system <stdio.h>:
47 #undef getline
48 #if HAVE_RAW_DECL_GETLINE
49 _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
50 "not universally present; use the gnulib module getline");
51 #endif
52
53 It is not possible to directly poison global variables. But it is
54 possible to write a wrapper accessor function, and poison that
55 (less common usage, like &environ, will cause a compilation error
56 rather than issue the nice warning, but the end result of informing
57 the developer about their portability problem is still achieved):
58 #if HAVE_RAW_DECL_ENVIRON
59 static inline char ***rpl_environ (void) { return &environ; }
60 _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");
61 # undef environ
62 # define environ (*rpl_environ ())
63 #endif
64 */
65 #ifndef _GL_WARN_ON_USE

67 # if 4 < __GNUC__ || (__GNUC__ == 4 && 3 <= __GNUC_MINOR__)

454 # Darwin 7.5 has nl_langinfo(CODESET), but sometimes its value is

456 # - It returns the empty string when LANG is set to a locale of the
457 # form ll_CC, although ll_CC/LC_CTYPE is a symlink to an UTF-8
458 # LC_CTYPE file.
459 # - The environment variables LANG, LC_CTYPE, LC_ALL are not set by
460 # the system; nl_langinfo(CODESET) returns "US-ASCII" in this case.
461 # - The documentation says:
462 # "... all code that calls BSD system routines should ensure
463 # that the const *char parameters of these routines are in UTF-8
464 # encoding. All BSD system functions expect their string
465 # parameters to be in UTF-8 encoding and nothing else."
466 # It also says
467 # "An additional caveat is that string parameters for files,
468 # paths, and other file-system entities must be in canonical
469 # UTF-8. In a canonical UTF-8 Unicode string, all decomposable
470 # characters are decomposed ..."
471 # but this is not true: You can pass non-decomposed UTF-8 strings
472 # to file system functions, and it is the OS which will convert
473 # them to decomposed UTF-8 before accessing the file system.
474 # - The Apple Terminal application displays UTF-8 by default.
475 # - However, other applications are free to use different encodings:
476 # - xterm uses ISO-8859-1 by default.
477 # - TextEdit uses MacRoman by default.
478 # We prefer UTF-8 over decomposed UTF-8-MAC because one should
479 # minimize the use of decomposed Unicode. Unfortunately, through the
480 # Darwin file system, decomposed UTF-8 strings are leaked into user
481 # space nevertheless.
482 # Then there are also the locales with encodings other than US-ASCII
483 # and UTF-8. These locales can be occasionally useful to users (e.g.
484 # when grepping through ISO-8859-1 encoded text files), when all their

454 # Darwin 7.5 has nl_langinfo(CODESET), but sometimes its value is

456 # - It returns the empty string when LANG is set to a locale of the
457 # form ll_CC, although ll_CC/LC_CTYPE is a symlink to an UTF-8
458 # LC_CTYPE file.
459 # - The environment variables LANG, LC_CTYPE, LC_ALL are not set by
460 # the system; nl_langinfo(CODESET) returns "US-ASCII" in this case.
461 # - The documentation says:
462 # "... all code that calls BSD system routines should ensure
463 # that the const *char parameters of these routines are in UTF-8
464 # encoding. All BSD system functions expect their string
465 # parameters to be in UTF-8 encoding and nothing else."
466 # It also says
467 # "An additional caveat is that string parameters for files,
468 # paths, and other file-system entities must be in canonical
469 # UTF-8. In a canonical UTF-8 Unicode string, all decomposable
470 # characters are decomposed ..."
471 # but this is not true: You can pass non-decomposed UTF-8 strings
472 # to file system functions, and it is the OS which will convert
473 # them to decomposed UTF-8 before accessing the file system.
474 # - The Apple Terminal application displays UTF-8 by default.
475 # - However, other applications are free to use different encodings:
476 # - xterm uses ISO-8859-1 by default.
477 # - TextEdit uses MacRoman by default.
478 # We prefer UTF-8 over decomposed UTF-8-MAC because one should
479 # minimize the use of decomposed Unicode. Unfortunately, through the
480 # Darwin file system, decomposed UTF-8 strings are leaked into user
481 # space nevertheless.
482 # Then there are also the locales with encodings other than US-ASCII
483 # and UTF-8. These locales can be occasionally useful to users (e.g.
484 # when grepping through ISO-8859-1 encoded text files), when all their

98 longword at a time. The tricky part is testing if *any of the four*
99 bytes in the longword in question are equal to c. We first use an xor
100 with repeated_c. This reduces the task to testing whether *any of the
101 four* bytes in longword1 is zero.
102
103 We compute tmp =
104 ((longword1 - repeated_one) & ~longword1) & (repeated_one << 7).
105 That is, we perform the following operations:
106 1. Subtract repeated_one.
107 2. & ~longword1.
108 3. & a mask consisting of 0x80 in every byte.
109 Consider what happens in each byte:
110 - If a byte of longword1 is zero, step 1 and 2 transform it into 0xff,
111 and step 3 transforms it into 0x80. A carry can also be propagated
112 to more significant bytes.
113 - If a byte of longword1 is nonzero, let its lowest 1 bit be at
114 position k (0 <= k <= 7); so the lowest k bits are 0. After step 1,
115 the byte ends in a single bit of value 0 and k bits of value 1.
116 After step 2, the result is just k bits of value 1: 2^k - 1. After
117 step 3, the result is 0. And no carry is produced.
118 So, if longword1 has only non-zero bytes, tmp is zero.
119 Whereas if longword1 has a zero byte, call j the position of the least
120 significant zero byte. Then the result has a zero at positions 0, ...,
121 j-1 and a 0x80 at position j. We cannot predict the result at the more
122 significant bytes (positions j+1..3), but it does not matter since we
123 already have a non-zero bit at position 8*j+7.
124
125 So, the test whether any byte in longword1 is zero is equivalent to
126 testing whether tmp is nonzero. */

214 GNU Coding Standards discourage the use of fseek, since it imposes
215 an arbitrary limitation on some 32-bit hosts. Remember that the
216 fseek module depends on the fseeko module, so we only have three
217 cases to consider:
218
219 1. The developer is not using either module. Issue a warning under
220 GNULIB_POSIXCHECK for both functions, to remind them that both
221 functions have bugs on some systems. _GL_NO_LARGE_FILES has no
222 impact on this warning.
223
224 2. The developer is using both modules. They may be unaware of the
225 arbitrary limitations of fseek, so issue a warning under
226 GNULIB_POSIXCHECK. On the other hand, they may be using both
227 modules intentionally, so the developer can define
228 _GL_NO_LARGE_FILES in the compilation units where the use of fseek
229 is safe, to silence the warning.
230
231 3. The developer is using the fseeko module, but not fseek. Gnulib
232 guarantees that fseek will still work around platform bugs in that
233 case, but we presume that the developer is aware of the pitfalls of
234 fseek and was trying to avoid it, so issue a warning even when
235 GNULIB_POSIXCHECK is undefined. Again, _GL_NO_LARGE_FILES can be
236 defined to silence the warning in particular compilation units.
237
238 Most gnulib clients that perform stream operations should fall into
239 category three. */

49 to a directory; and due to the bug of ignoring trailing
50 slash, Solaris 9 would end up successfully unlinking the
51 symlink instead of the directory. Technically, we could use
52 realpath to find the canonical directory name to attempt
53 deletion on. But that is a lot of work for a corner case; so
54 we instead just use an lstat on the shortened name, and

6 # gl_WARN_ON_USE_PREPARE(INCLUDES, NAMES)
7 # ---------------------------------------
8 # For each whitespace-separated element in the list of NAMES, define
9 # HAVE_RAW_DECL_name if the function has a declaration among INCLUDES
10 # even after being undefined as a macro.
11 #
12 # See warn-on-use.h for some hints on how to poison function names, as
13 # well as ideas on poisoning global variables and macros. NAMES may
14 # include global variables, but remember that only functions work with
15 # _GL_WARN_ON_USE. Typically, INCLUDES only needs to list a single
16 # header, but if the replacement header pulls in other headers because
17 # some systems declare functions in the wrong header, then INCLUDES
18 # should do likewise.
19 #
20 # If you assume C89, then it is generally safe to assume declarations
21 # for functions declared in that standard (such as gets) without
22 # needing gl_WARN_ON_USE_PREPARE.

20 # The typical skeleton of a test looks like this:
21 #
22 # #!/bin/sh
23 # : ${srcdir=.}
24 # . "$srcdir/init.sh"; path_prepend_ .
25 # Execute some commands.
26 # Note that these commands are executed in a subdirectory, therefore you
27 # need to prepend "../" to relative filenames in the build directory.
28 # Set the exit code 0 for success, 77 for skipped, or 1 or other for failure.
29 # Use the skip_ and fail_ functions to print a diagnostic and then exit
30 # with the corresponding exit code.

39 # Running a single test, with verbose output:
40 # $ make check TESTS=test-foo.sh VERBOSE=yes
41 #
42 # Running a single test, with single-stepping:
43 # 1. Go into a sub-shell:
44 # $ bash
45 # 2. Set relevant environment variables from TESTS_ENVIRONMENT in the
46 # Makefile:
47 # $ export srcdir=../../tests # this is an example
48 # 3. Execute the commands from the test, copy&pasting them one by one:
49 # $ . "$srcdir/init.sh"; path_prepend_ .
50 # ...
51 # 4. Finally
52 # $ exit
53

55 # hoops to get the right exit status transported through the handler.
