01 Dec 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, Makefile.am, |
| 6 |
localdecls.h, scripts/Makefile.am, scripts/gen_symbol_version_map.awk, |
| 7 |
scripts/gen_symbol_header.awk, src/Makefile.am, src/symbols.in, |
| 8 |
src/libsandbox.c, src/getcwd.c, src/sandbox.c, data/sandbox.bashrc: |
| 9 |
|
| 10 |
Use versioned symbols on supported libc's for functions we wrap, as well as |
| 11 |
provide all versions of specific functions. Some syntax cleanups. |
| 12 |
|
| 13 |
Only check SANDBOX_ACTIVE, and not its value. More BASH_ENV fixes. |
| 14 |
|
| 15 |
Rename configure.in to configure.ac. |
| 16 |
|
| 17 |
Fix non-versioned libc's to also prepend '__' to internal symbols by using |
| 18 |
strong aliases. |
| 19 |
|
| 20 |
Remove the SB_STATIC and including of getcwd.c, etc voodoo, as we new use a |
| 21 |
symbol map, and all non-exported symbols are local. Cleanup getcwd.c, as |
| 22 |
the generic getcwd for older 2.4 kernels do not work properly anyhow, and |
| 23 |
just makes things slower. Some other warning fixes. |
| 24 |
|
| 25 |
28 Nov 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, sandbox.c, |
| 26 |
sandbox_fdutils.c: |
| 27 |
|
| 28 |
Detect if we on 64bit arch automatically. |
| 29 |
|
| 30 |
Update contact email. Fix quoting. |
| 31 |
|
| 32 |
Revert 64bit arch test, as we should build the 32bit version without full |
| 33 |
path checking as well, and add --enable-multilib switch to configure. |
| 34 |
|
| 35 |
* sandbox-1.2.14 (2005/11/28) |
| 36 |
|
| 37 |
28 Nov 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c, |
| 38 |
sandbox.c, sandbox.h, sandbox.bashrc: |
| 39 |
|
| 40 |
Check generic getcwd()'s return as well for validity, bug #101728. |
| 41 |
|
| 42 |
Cleanup environ variables. |
| 43 |
|
| 44 |
Rather check SANDBOX_ACTIVE if we are already running. Set SANDBOX_ACTIVE |
| 45 |
to readonly in sandbox.bashrc. |
| 46 |
|
| 47 |
Make sure we use our bashrc. |
| 48 |
|
| 49 |
01 Nov 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c: |
| 50 |
|
| 51 |
Do not pass mode to true_open and true_open64 if not needed. Should fix a |
| 52 |
segfault in some cases. |
| 53 |
|
| 54 |
* sandbox-1.2.13 (2005/09/12) |
| 55 |
|
| 56 |
12 Sep 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, libsandbox.c: |
| 57 |
|
| 58 |
Do not handle adding working directory to SANDBOX_WRITE, as portage does it |
| 59 |
itself. |
| 60 |
|
| 61 |
Make libsb_fini() do cleanup a bit more complete just in case we get another |
| 62 |
uClibc 'call preloaded library fini before that of app' issue ... probably |
| 63 |
will not help much, but we try. |
| 64 |
|
| 65 |
04 Sep 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c: |
| 66 |
|
| 67 |
Also allow symlink() system call to operate on a symlink in a writable path |
| 68 |
that points to non-writable path, bug #104711. |
| 69 |
|
| 70 |
* sandbox-1.2.12 (2005/08/05) |
| 71 |
|
| 72 |
05 Aug 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c, |
| 73 |
sandbox.h: |
| 74 |
|
| 75 |
Do not give an access violation if the access() system call do not have |
| 76 |
write/read access - it does not actually modify, so we only need to return |
| 77 |
not being able to write/read. Noted by Andres Loeh <kosmikus@gentoo.org>, |
| 78 |
bug #101433. |
| 79 |
|
| 80 |
If we are called from the command line, do not care about PORTAGE_TMPDIR, |
| 81 |
and make the current directory the work directory. Also rename the variable |
| 82 |
portage_tmp_dir to work_dir. |
| 83 |
|
| 84 |
Remove the tmp_dir variable - we do not need it. |
| 85 |
|
| 86 |
Improve error handling for get_sandbox_*_envvar() functions. |
| 87 |
|
| 88 |
01 Aug 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c: |
| 89 |
|
| 90 |
Still do normal log if debugging is requested. |
| 91 |
|
| 92 |
Add support for SANDBOX_VERBOSE (enabled by default). Adjust SANDBOX_DEBUG |
| 93 |
to only enable if equal to "1" or "yes". |
| 94 |
|
| 95 |
Add /dev/tts to write permit, bug #42809. |
| 96 |
|
| 97 |
27 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h, |
| 98 |
sandbox_futils.c: |
| 99 |
|
| 100 |
Do not resolve symlinks in PORTAGE_TMPDIR in sandbox .. we will handle that |
| 101 |
in libsandbox .. bug #100309. |
| 102 |
|
| 103 |
22 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.h: |
| 104 |
|
| 105 |
Print all logging to stderr, bug #90343, comment #15, by Zac Medico. |
| 106 |
|
| 107 |
* sandbox-1.2.11 (2005/07/14) |
| 108 |
|
| 109 |
14 July 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c: |
| 110 |
Fix getcwd, bug #98419. |
| 111 |
|
| 112 |
08 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c, |
| 113 |
libsandbox.c: |
| 114 |
- Try to cleanup and make error handling/printing consistent. |
| 115 |
- Remove old logs if present and conflicting with current. |
| 116 |
- Fix compile error with previous change, and return rather then exit(). |
| 117 |
|
| 118 |
07 July 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c, |
| 119 |
sandbox.h, sandbox_futils.c: |
| 120 |
- Fix possible segfault in env init code. |
| 121 |
- Major cleanup of sandbox_futils.c. Removed most of the functions as we now |
| 122 |
write to /var/log/sandbox/, so in theory do not need all that. |
| 123 |
- Redo the interface of the get_* functions so that we do not leak memory. |
| 124 |
- Remove sandbox_dir and co - we are not using it anymore. |
| 125 |
- Remove unused includes and variables. |
| 126 |
- Only declare functions in sandbox_futils.c that are used in libsandbox.c when |
| 127 |
OUTSIDE_LIBSANDBOX is not defined. |
| 128 |
- Cleanup access/log printing. Make access printing honour NOCOLOR. Fix log |
| 129 |
printing's last line not honouring NOCOLOR. |
| 130 |
|
| 131 |
06 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.h, sandbox_futils.c, |
| 132 |
libsandbox.c: |
| 133 |
- Change log dir to /var/log/sandbox/. Make sure the sandboxed process cannot |
| 134 |
write to it. |
| 135 |
- Clean up logging in libsandbox.c, and hopefully make it more consistant. |
| 136 |
- Add check_prefixes() with major cleanup on check_access(). |
| 137 |
- Cleanup init_env_entries() and check_prefixes(). |
| 138 |
|
| 139 |
05 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h, |
| 140 |
sandbox_futils.c, libsandbox.c: |
| 141 |
Remove unused 'pids file' code. |
| 142 |
|
| 143 |
* sandbox-1.2.10 (2005/07/03) |
| 144 |
|
| 145 |
03 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c: |
| 146 |
Add PREDICT items for nss-db, bug #92079. Patch from Robin Johnson. |
| 147 |
|
| 148 |
17 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c: |
| 149 |
General cleanups: |
| 150 |
- Remove fooling around with exit codes - we error out on presence of a log |
| 151 |
anyhow. |
| 152 |
- Move get_sandbox_*_envvar() to sandbox_setup_environ(), as its more |
| 153 |
appropriate there. |
| 154 |
|
| 155 |
12 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c: |
| 156 |
Cleanup the fail_nametoolong stuff a bit more. |
| 157 |
|
| 158 |
11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c: |
| 159 |
Remove hopefully the last ld.so.preload bits we do not use anymore. |
| 160 |
|
| 161 |
11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c: |
| 162 |
Remove the unneeded canonicalize() calls in the wrappers - we do it anyhow |
| 163 |
in check_syscall(). Should speed things up a bit (at least for the getcwd() |
| 164 |
and long path name test it goes down to under a second, and not 10+ seconds |
| 165 |
like before). Also warn if we skip checking due to the canonicalized path |
| 166 |
being too long. |
| 167 |
|
| 168 |
11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c: |
| 169 |
More comment/readability cleanups. |
| 170 |
|
| 171 |
10 June 2005; Martin Schlemmer <azarah@gentoo.org> canonicalize.c, getcwd.c, |
| 172 |
sandbox_futils.c, libsandbox.c: |
| 173 |
Some strncpy/strncat and other cleanups. |
| 174 |
|
| 175 |
* sandbox-1.2.9 (2005/06/09) |
| 176 |
|
| 177 |
09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c: |
| 178 |
Move symlink hack down a bit to try and minimize on the amount of lstat() |
| 179 |
calls we do. |
| 180 |
|
| 181 |
09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c: |
| 182 |
Add hack to allow writing to /proc/self/fd (or /dev/fd), bug #91516. |
| 183 |
|
| 184 |
09 June 2005; Martin Schlemmer <azarah@gentoo.org> symbols.in, libsandbox.c: |
| 185 |
Add wrapper for access() function, bug #85413. |
| 186 |
|
| 187 |
09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c: |
| 188 |
Use generic getcwd() implementation from uclibc - should be more portable |
| 189 |
and looks a bit cleaner. |
| 190 |
|
| 191 |
09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c: |
| 192 |
Make sure our true_* pointers are initialized to NULL, and that we check for |
| 193 |
all references that they are valid. |
| 194 |
|
| 195 |
09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c: |
| 196 |
Be default we will fail if the path name we try to canonicalize is too long. |
| 197 |
This however could cause issues with some things (bug #94630 and #21766), so |
| 198 |
if fail_nametoolong == 0, canonicalize() will return a null length string and |
| 199 |
do not fail. |
| 200 |
|
| 201 |
08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c: |
| 202 |
Do not abort if TMPDIR is not valid, but rather use '/tmp', bug #94360. Also |
| 203 |
make sure we re-export the new TMPDIR environment variable. |
| 204 |
|
| 205 |
08 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c: |
| 206 |
Fix incorrect free of non-malloc'd array, bug #92313 and #94020. Fix noted |
| 207 |
by Marcus D. Hanwell <cryos@gentoo.org>. |
| 208 |
|
| 209 |
08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c: |
| 210 |
Add /dev/console to write list, bug #38588. |
| 211 |
|
| 212 |
* sandbox-1.2.8 (2005/05/13) |
| 213 |
|
| 214 |

General cleanups. |
| 217 |
|
| 218 |
13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c, |
| 219 |
sandbox.h: |
| 220 |
Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent. |
| 221 |
|
| 222 |
13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c, |
| 223 |
sandbox.h, sandbox_futils.c: |
| 224 |
Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log() |
| 225 |
to use TMPDIR if present in environment. |
| 226 |
|
| 227 |
13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c: |
| 228 |
Remove sandbox_log_file from main() as its no longer used. |
| 229 |
|
| 230 |
13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h, |
| 231 |
sandbox_futils.c: |
| 232 |
Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG |
| 233 |
if already exported when sandbox started). Fix get_sandbox_log() and new |
| 234 |
get_sandbox_debug_log() to not use already exported environment variables if |
| 235 |
they have '/' in them. Use snprintf()'s instead of strncpy()'s. More |
| 236 |
SB_PATH_MAX fixes. |
| 237 |
|
| 238 |
* sandbox-1.2.7 (2005/05/12) |
| 239 |
|
| 240 |
12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h, |
| 241 |
sandbox_futils.c: |
| 242 |
More path limit fixes. Declare SB_BUF_LEN global and use it where needed. |
| 243 |
|
| 244 |
12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c: |
| 245 |
Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string |
| 246 |
with '(null)' in it if we did not call sandbox with absolute path. |
| 247 |
|
| 248 |
12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c: |
| 249 |
Set SANDBOX_ON *before* doing the child's env stuff, else its not set |
| 250 |
for the child. |
| 251 |
|
| 252 |
12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c: |
| 253 |
Remove global preload_adaptable as it is no longer used. |
| 254 |
|
| 255 |
12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c: |
| 256 |
Rewrite environment stuff to only be set when execve'ing the child process |
| 257 |
to try and avoid issues like bug #91541 that causes sandbox to crash if |
| 258 |
we set LD_PRELOAD sandbox side already. |
| 259 |
|
| 260 |
11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c: |
| 261 |
Move print_sandbox_log() up to make things neater. |

|
| 263 |

| 264 |
Remove load_preload_libs(), as its not used anymore. |
| 265 |
|
| 266 |
11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h: |
| 267 |
Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine. |
| 268 |
|
| 269 |
11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h: |
| 270 |
Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use. |
| 271 |
|
| 272 |
11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h: |
| 273 |
Remove ld.so.preload crap - we are not going to use it again. |
| 274 |
|
| 275 |
10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c: |
| 276 |
Fix typo in code that checks if we got valid group information, causing a |
| 277 |
segmentation fault, bug #91637. |
| 278 |
|
| 279 |
* sandbox-1.2.6 (2005/05/10) |
| 280 |
|
| 281 |
10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c: |
| 282 |
Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox |
| 283 |
for some odd reason, bug #91541. |
| 284 |
|
| 285 |
09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c: |
| 286 |
Fix typo (sizeof -> strlen). |
| 287 |
|
| 288 |
08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c: |
| 289 |
rewrote the sbcontext caching code so it accounts for env changes since lib |
| 290 |
initialization. |
| 291 |
|
| 292 |
05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c: |
| 293 |
We create libctest.c via configure, so no need to keep it around. Do some |
| 294 |
cleanup related to libctest.c and libctest during configure. |
| 295 |
|
| 296 |
04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c: |
| 297 |
Add rename support of symlinks pointing to protected files/directories. |
| 298 |
|
| 299 |
* sandbox-1.2.5 (2005/05/04) |
| 300 |
|
| 301 |
04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c, |
| 302 |
sandbox.bashrc: |
| 303 |
Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is |
| 304 |
already set, init of the env vars fails for some reason, so do this later on, |
| 305 |
and do not warn (bug #91431). |
| 306 |
|
| 307 |
03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h, |
| 308 |
sandbox.bashrc: |
| 309 |
Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc. |
| 310 |
|
| 311 |
* sandbox-1.2.4 (2005/05/03) |
| 312 |
|
| 313 |
03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c: |
| 314 |
Do not init the env entries with each call, as it creates too many calls to |
| 315 |
lstat, etc. Should speedup things a bit, bug #91040. |
| 316 |
|
| 317 |
03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c: |
| 318 |
Add /dev/pty to default write list. Noticed by Morfic. |
| 319 |
|
| 320 |
02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h, |
| 321 |
sandbox.h: |
| 322 |
uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't |
| 323 |
exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc. |
| 324 |
|
| 325 |
* sandbox-1.2.3 (2005/04/29) |
| 326 |
|
| 327 |
29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in: |
| 328 |
Do not check for (*&#$(* CXX or F77. |
| 329 |
|
| 330 |
29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c: |
| 331 |
Do not append '/' to pathname in filter_path() if it already ends with it. |
| 332 |
|
| 333 |
28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in: |
| 334 |
With az's help, clean up autotools to work with cross-compiling. |
| 335 |
|
| 336 |
* sandbox-1.2.2 (2005/04/28) |
| 337 |
|
| 338 |
28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c: |
| 339 |
Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm |
| 340 |
have issues; bug #90592. |
| 341 |
|
| 342 |
* sandbox-1.2.1 (2005/04/23) |
| 343 |
|
| 344 |

Make sure all functions used in libsandbox.c is declared static. Define |
| 347 |
SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than |
| 348 |
linking with its object. Hopefully this will fix bug #90153. |

22 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c: |
| 353 |
Allow lchown a symlink in write-allowed path pointing to write-denied |
| 354 |
target. |
| 355 |
|
| 356 |
21 Mar 2005; Marius Mauch <genone@gentoo.org> libsandbox.c: |
| 357 |
Also show resolved symlink names in the log. |
| 358 |
|
| 359 |
14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, libsandbox.c: |
| 360 |
Seems -nostdlib was the problem with the constructor/destructor - remove it |
| 361 |
from Makefile.am, and change the constructor/destructor names again. |
| 362 |
|
| 363 |
14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c: |
| 364 |
Also rename the _init() and _fini() declarations. |
| 365 |
|
| 366 |
14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c: |
| 367 |
Fixup the constructor/destructor function names again (they should be _init() |
| 368 |
and _fini() it seems, and not being called caused sandbox_lib_path to be |
| 369 |
unset, and thus breaking the execve() wrapper's LD_PRELOAD protection). |
| 370 |
Add both the path in given SANDBOX_x variable, as well as its symlink |
| 371 |
resolved path in init_env_entries(). Modify filter_path() to be able to |
| 372 |
resolve paths without resolving symlinks, as well as to be able to resolve |
| 373 |
symlinks. Fix a possible segfault in check_access(). Add symlink resolving |
| 374 |
to check_access() resolving bug #31019. Add 'hack' for unlink, as the fix |
| 375 |
for bug #31019 cause access violations if we try to remove a symlink that is |
| 376 |
not in protected path, but points to a protected path. Fix a memory leak in |
| 377 |
sandbox.c (sandbox_pids_file in main()). Fix the realpath() calls in main() |
| 378 |
(sandbox.c) being unchecked. Fix the debug logname not having the pid in it |
| 379 |
(pid_string was uninitialized). General syntax cleanups. |
| 380 |
|
| 381 |
09 Mar 2005; Brian Harring <ferringb@gentoo.org> sandbox.c: Fixed the |
| 382 |
infamous "pids file is not a regular file" w/out newline bug. |
| 383 |
|
| 384 |
09 Mar 2005; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in: |
| 385 |
Correct libc_version path detection, since it was screwing up if libdir != |
| 386 |
"/lib/". |
| 387 |
|
| 388 |
02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c: |
| 389 |
Hack to make sure sandboxed process cannot remove a device node, bug #79836. |
| 390 |
|
| 391 |
02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am: |
| 392 |
Fix symbols.in not added to dist. |
| 393 |
|
| 394 |
02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c, |
| 395 |
getcwd.c, libsandbox.c, sandbox.c, sandbox.h, sandbox_futils.c: |
| 396 |
White space fixes. |
| 397 |
|
| 398 |
02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c, |
| 399 |
configure.in, getcwd.c, libsandbox.c, symbols.in: |
| 400 |
Fix inverse test logic in canonicalize.c, use a strncpy. Fix gcc warning in |
| 401 |
getcwd.c. Add symbols.in and logic to Makefile.am to generate symbol versions |
| 402 |
for glibc and other libc's that use this. Update libsandbox.c to use these |
| 403 |
symbol versions if available. Fix exec wrapper to re-export LD_PRELOAD if the |
| 404 |
process unset it. |
| 405 |
|
| 406 |
01 Mar 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c: |
| 407 |
killed off _init and _fini in favor of |
| 408 |
void __attribute__ ((constructor)) init_func and |
| 409 |
void __attribute__ ((destructor)) closing_func. _(init|func) were deprecated. |
| 410 |
|
| 411 |
06 Dec 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, libsandbox.c, |
| 412 |
canonicalize.c, getcwd.c: Fixed compilation *again*. Hopefully cvs is done |
| 413 |
having the hick-ups. |
| 414 |
|
| 415 |
04 Dec 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, getcwd.c, |
| 416 |
Makefile.am: Fixed compilation. |
| 417 |
|
| 418 |
01 Dec 2004; Brian Harring <ferringb@gentoo.org> aclocal.m4: |
| 419 |
Gutted the bugger so it stops checking for a c++ and fortran compiler. |
| 420 |
Do *not* regenerate aclocal.m4 for making a release until a better |
| 421 |
solution is created. |
| 422 |
|
| 423 |
20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, sandbox_futils.c: |
| 424 |
Removal of more hardcoded paths. |
| 425 |
|
| 426 |
20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in, |
| 427 |
sandbox_futils.c: tweaks to install sandbox.bashrc, and use it. |
| 428 |
|
| 429 |
19 Nov 2004; Brian Harring <ferringb@gentoo.org>: |
| 430 |
Sandbox is now autotooled, create-localdecls needs to be killed and the code |
| 431 |
shifted into configure.in. Currently builds *one* libsandbox.so- if multiple |
| 432 |
are desired (-m64 and -m32 for amd64), the ebuild should do it (imo). |
| 433 |
To get to a point of testing, automake && autoconf; created requisite files w/ |
| 434 |
a(utomake|clocal)-1.8, and autoconf 2.59. Installs to /usr/, instead of |
| 435 |
/lib and /usr/lib/portage/bin. |
| 436 |
|
| 437 |
14 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox.c: |
| 438 |
closing out bug #70225, potential overflow of the sandbox_pids_file var. |
| 439 |
|
| 440 |
07 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c: c99 standard, |
| 441 |
(think it was at least) allows intermixing of code and data segments. bug #70351 |
| 442 |
should be fixed by this. |
| 443 |
|
| 444 |
03 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox_futils.c: |
| 445 |
futils fix from bug #65201 via solar, and libsandbox log path checks via #69137 |
| 446 |
|
| 447 |
02 Aug 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Code from |
| 448 |
Seth Robertson that tracked down all adjuct flags for read operations that |
| 449 |
do not invoke a write operation. |
| 450 |
|
| 451 |
04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c: |
| 452 |
Another fix from jstubbs regarding a free() on a stack variable for the |
| 453 |
environment -- tracking now prevents extraneous free()'s segfault. |
| 454 |
|
| 455 |
04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c: |
| 456 |
J. Stubbs tracked down a new bug where mkdir was failing to the patch on |
| 457 |
the lstat in mkdir... it now only returns 0 or -1 as documented for mkdir. |
| 458 |
Also remove the errno = ESUCCESS settings as documentation points out that |
| 459 |
a library isn't allowed to do that. |
| 460 |
|
| 461 |
04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Added a |
| 462 |
file_security_check() function to check random potential exploits on files |
| 463 |
that sandbox is to load and read -- Normally sandboxpids.tmp. This fixes |
| 464 |
the 'system-crippling' exploits (bug 21923) and catches a few other |
| 465 |
potential problems. |
| 466 |
|
| 467 |
20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> Makefile: Updates for |
| 468 |
32/64 bit sandbox. Made CC and LD '?=' values to allow passed in CC to work. |
| 469 |
|
| 470 |
20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: |
| 471 |
bug 42048 -- Fixed the lstat/errno conditions for mkdir <caleb@g.o>. |
| 472 |
Added the 64/32 bit sandbox patch for AMD64 bug 32963 <brad/azarah>. |
| 473 |
|
| 474 |
29 Feb 2004; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c : |
| 475 |
Fix permissions and group of pids file and logs. Permissions should be 0664 |
| 476 |
and group should be 'portage'. Bug #34260. |
| 477 |
|
| 478 |
28 Feb 2004; Martin Schlemmer <azarah@gentoo.org> libsandbox.c : |
| 479 |
Besides a small cleanup, redo how we replace LD_PRELOAD in the environ passed |
| 480 |
to the real execve (in our execve wrapper). Seems that on some arches (sparc |
| 481 |
among others) do not allow us to tamper with the readonly copy passed to |
| 482 |
execve, so pass our own copy of the environment. Bug #42290. |
| 483 |
|
| 484 |
11 Jan 2004; Nicholas Jones <carpaski@gentoo.org> create-decls: |
| 485 |
Changed tail to head and added a notice about duration of glibc check. |
| 486 |
|
| 487 |
21 Dec 2003; Nicholas Jones <carpaski@gentoo.org> create-decls: |
| 488 |
Changed the glibc subversion check to use /usr/bin/* instead of /bin/sh |
| 489 |
as there isn't a guarentee that it is dynamic. |
| 490 |
|
| 491 |
02 Nov 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c : |
| 492 |
If 'file' passed to before_syscall(const char *func, const char *file) is |
| 493 |
invalid, we should set errno to ENOENT, and not EINVAL. This should |
| 494 |
close bug #32238. |
| 495 |
|
| 496 |
14 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c : |
| 497 |
Fix a bug that occurs mainly on 64bit arch, where the file passed to |
| 498 |
the functions we wrap, is invalid, and then cause canonicalize to pass |
| 499 |
garbage to before_syscall(), thanks to great detective work from |
| 500 |
Andrea Luzzardi <al@sig11.org> (bug #29846). |
| 501 |
|
| 502 |
13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls : |
| 503 |
Add a uClibc detection patch from Peter S. Mazinger <ps.m@gmx.net>. |
| 504 |
|
| 505 |
13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c : |
| 506 |
Fix a bug in libsandbox.c 's checking in the rename wrapper - it basically |
| 507 |
only checked the destination patch, and not the source, so we could move |
| 508 |
a protected file to a unprotected directory, and then delete/modify it. |
| 509 |
Thanks to Andrea Luzzardi (scox) <al@sig11.org>, bug #30992, for this fix. |
| 510 |
|
| 511 |
12 Oct 2003; Nicholas Jones <carpaski@gentoo.org> sandbox.c : |
| 512 |
Added python2.3 to the predict section/variable. |
| 513 |
|
| 514 |
28 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c, |
| 515 |
sandbox.h, sandbox_futils.c : |
| 516 |
Add support to set the pids file via SANDBOX_PIDS_FILE at startup. If |
| 517 |
it is not set, it will revert to its old value. |
| 518 |
|
| 519 |
27 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c : |
| 520 |
Fix our mkdir wrapper to check if the dir exist, and return EEXIST if so, |
| 521 |
rather than failing with a violation, bug #29748. |
| 522 |
|
| 523 |
27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c : |
| 524 |
Fix canonicalize() to ignore calls with path = "". |
| 525 |
|
| 526 |
27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c, |
| 527 |
sandbox_futils.c, canonicalize.c : |
| 528 |
Once again coreutils fails, as my systems had 2.5 kernel, the getcwd system |
| 529 |
call handled strings larger than PATH_MAX (bug #21766). It however does not |
| 530 |
work the same on 2.4 kernels. |
| 531 |
|
| 532 |
To fix, I added the posix implementation of getcwd() (from glibc cvs) that |
| 533 |
do not need the system call. We use the default getcwd() function via a |
| 534 |
wrapper (egetcwd), and then lstat the returned path. If lstat fails, it |
| 535 |
means the current directory was removed, OR that the the system call for |
| 536 |
getcwd failed (curious is that it do not fail and return NULL or set |
| 537 |
errno, but rather just truncate the retured directory - usually from the |
| 538 |
start), and if so, we use the generic getcwd() function (__egetcwd). Note |
| 539 |
that we do not use the generic version all the time, as it calls lstat() |
| 540 |
a great number of times, and performance degrade much. |
| 541 |
|
| 542 |
29 Jun 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls, |
| 543 |
libsandbox.c : |
| 544 |
Make sure SB_PATH_MAX will not wrap. Fix two possible memory leaks. |
| 545 |
|
| 546 |
22 Jun 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, canonicalize.c |
| 547 |
create-localdecls : |
| 548 |
When checking path names of files accessed, we need to canonicalize it, else |
| 549 |
it may be a symlink in a 'write allowed' directory pointing to a file in a |
| 550 |
directory we should not have write access to. |
| 551 |
|
| 552 |
With something like coreutils-5.0, we have two problems: |
| 553 |
1) One of the tests checks if getcwd() can return a path longer than |
| 554 |
PATH_MAX. This test then tries to create a dir which even while |
| 555 |
created local (mkdir("conftest2")), it ends up being resolved with |
| 556 |
a name that is much larger than PATH_MAX. The problem now is that |
| 557 |
canonicalize() have undefined behaviour when the path was too long |
| 558 |
(returned wrongly truncated paths, etc), and pass the wrong path to |
| 559 |
before_syscall() (causing the bogus sandbox violations). |
| 560 |
2) The ecanonicalize() function we used, along with the canonicalize() |
| 561 |
function did not support longer than PATH_MAX. This is partly a |
| 562 |
cause for 1), but the error checking (rather lack of it) of calls |
| 563 |
to erealpath() in canonicalize() was the prime reason for 1). |
| 564 |
|
| 565 |
As we do not use this canonicalized name to call the function, we resolve this |
| 566 |
by fixing canonicalize() to do better error checking, and ecanonicalize() as |
| 567 |
well as all functions in libsandbox.c to use a PATH_MAX of 'PATH_MAX * 2'. |
| 568 |
While they will resolve paths properly now, and can check if a write/read is |
| 569 |
allowed, the functions called from the sandboxed environment will still work |
| 570 |
as expected. |
| 571 |
|
| 572 |
This should resolve bug #21766. |
| 573 |
|
| 574 |
06 Apr 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c : |
| 575 |
For some reason sandbox fails with a 'open_wr' if you run 'locale -a' under |
| 576 |
it (bug #16298). |
| 577 |
|
| 578 |
Problem is that for some reason locale fopen's locale.alias with mode "rm". |
| 579 |
|
| 580 |
------------------------------------------------------- |
| 581 |
nosferatu root # grep fopen locale.log |
| 582 |
fopen("/usr/share/locale/locale.alias", "rm"ACCESS DENIED open_wr: /usr/share/locale/locale.alias |
| 583 |
nosferatu root # |
| 584 |
-------------------------------------------------------- |
| 585 |
|
| 586 |
I checked the source of locale, but it have fopen with mode 'r', so |
| 587 |
not sure where the "rm" mode comes from. Anyhow, changed the check in |
| 588 |
before_syscall_open_char() to also see mode "rm" as readonly. |
| 589 |
|
| 590 |
23 Feb 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls : |
| 591 |
|
| 592 |
Add glibc-2.3 support. |
| 593 |
|
| 594 |
22 Feb 2003; Martin Schlemmer <azarah@gentoo.org> sandbox.c : |
| 595 |
|
| 596 |
Some /etc/ld.so.preload fixes. Just changed the #if defines to cover all |
| 597 |
operations releated to preload, as well as only try to modify ld.so.preload |
| 598 |
if we can. Also modify to write the pid to /tmp/sandboxpids.tmp even when |
| 599 |
not using ld.so.preload. Fix to not write this instance of sandbox's pid |
| 600 |
to /tmp/sandboxpids.tmp on exit if this is not the last sandbox running. |
| 601 |
|
| 602 |
22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> Makefile : |
| 603 |
|
| 604 |
Changed the LD to CC for hppa. |

|
| 606 |
22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls : |
| 607 |
|

|
| 610 |
17 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls : |
| 611 |
|
| 612 |
Added parisc to BROKEN_RTLD_ARCHLIST to see if it we can fix the relocation probs. |
| 613 |
|
| 614 |
09 Jan 2003; J Robert Ray <jrray@gentoo.org> sandbox.c : |
| 615 |
|
| 616 |
Don't segfault if $HOME isn't set, set $HOME to "/" instead. Fixes bug 10868. |
| 617 |
|
| 618 |
16 Dec 2002; Martin Schlemmer <azarah@gentoo.org> create-localdecls : |
| 619 |
|
| 620 |
Fix memory leak for mips, bug #12236. Thanks to Torgeir Hansen <torgeir@trenger.ro> |
| 621 |
for this fix. |
| 622 |
|
| 623 |
4 Dec 2002; J Robert Ray <jrray@gentoo.org> sandbox.h sandbox_futils.c : |
| 624 |
|
| 625 |
sandbox_futils defined a dirname() function that was masking the same |
| 626 |
function in glibc and was broken (e.g.: SANDBOX_DIR was being set to |
| 627 |
'/usr/lib/portage/bi/'). Fixed function to return expected results and |
| 628 |
renamed it to sb_dirname() to no longer mask the glibc function. Closes bug |
| 629 |
11231. |
| 630 |
|
| 631 |
4 Dec 2002; Martin Schlemmer <azarah@gentoo.org> : |
| 632 |
|
| 633 |
Fix a segfault in libsandbox.c if canonicalize() was called with |
| 634 |
first parameter = NULL. |
| 635 |
|
| 636 |
1 Sep 2002; Martin Schlemmer <azarah@gentoo.org> : |
| 637 |
|
| 638 |
Fix my braindead 'return 1;' in a void function. Updated sandbox.c, |
| 639 |
cleanup() for this. |
| 640 |
|
| 641 |
Change cleanup() in sandbox.c not to exit with fail status if |
| 642 |
the pidsfile is missing. We really should still display sandbox |
| 643 |
violations if they occured. |
| 644 |
|
| 645 |
31 Aug 2002; Martin Schlemmer <azarah@gentoo.org> : |
| 646 |
|
| 647 |
Update cleanup() in sandbox.c to remove the PIDSFILE if this is |
| 648 |
the last sandbox running. |
| 649 |
|
| 650 |
25 Aug 2002; Martin Schlemmer <azarah@gentoo.org> : |

|
| 654 |
22 Aug 2002; Martin Schlemmer <azarah@gentoo.org> : |
| 655 |
|
| 656 |
Add copyrights to sandbox.h and sandbox_futils.h. If wrong, the |
| 657 |
parties involved should please contact me so that we can fix it. |
| 658 |
|
| 659 |
Add opendir wrapper to libsandbox.c. |
| 660 |
|
| 661 |
21 Aug 2002; Martin Schlemmer <azarah@gentoo.org> : |
| 662 |
|
| 663 |
Do some more cleanups to ecanonicalize(), as it dropped filenames in |
| 664 |
rare cases (after my symlink cleanups), and caused glibc to bork. |
| 665 |
These fixes went into canonicalize.c. |
| 666 |
|

The new canonicalize() function in libsandbox.c also resolved symlinks, |
| 675 |
which caused on cleaning sandbox errors if the symlink pointed to a |
| 676 |
file in the live root. Ripped out canonicalize() and realpath() from |
| 677 |
glibc; removed the symlink stuff, and changed them to ecanonicalize() |
| 678 |
and erealpath(). |

Ripped out all the wrappers, and implemented those of InstallWatch. |
| 683 |
Losts of cleanups and bugfixes. Implement a execve that forces |
| 684 |
$LIBSANDBOX in $LD_PRELOAD. We can now thus do away with the feared |
| 685 |
/etc/ld.so.preload (*g*) ... Made the needed changes to sandbox.c, |
| 686 |
sandbox.h and sandbox_futils.c. Rewrote the Makefile for most |
| 687 |
parts; it now have an install target. |
| 688 |
|
| 689 |
Reformat the whole thing to look somewhat like the reworked sandbox.c |
| 690 |
and new sandbox.h and sandbox_futils.c from: |
