2011-09-18Shorten compile commands run by the build systemTheodore Ts'o1-0/+1
The DEFS line in MCONFIG had gotten so long that it exceeded 4k, and this was starting to cause some tools heartburn. It also made "make V=1" almost useless, since trying to following the individual commands run by make was lost in the noise of all of the defines. So fix this by putting the configure-generated defines in lib/config.h and the directory pathnames to lib/dirpaths.h. In addition, clean up some vestigal defines in configure.in and in the Makefiles to further shorten the cc command lines. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
2010-05-17libe2p, libext2fs: Update file copyright permission states to match COPYINGTheodore Ts'o1-2/+2
The top-level COPYING file states that the e2p and ext2fs libraries are available under the LGPLv2. The files were incorrectly labelled. Alex Thomas/Luster has been consulted wrt to the ext3_extents.h file; the rest of the files were primarily authored by Theodore Ts'o. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>

2007-12-05libext2fs: Add checks to prevent integer overflows passed to malloc()Theodore Ts'o1-1/+1
This addresses a potential security vulnerability where an untrusted filesystem can be corrupted in such a way that a program using libext2fs will allocate a buffer which is far too small. This can lead to either a crash or potentially a heap-based buffer overflow crash. No known exploits exist, but main concern is where an untrusted user who possesses privileged access in a guest Xen environment could corrupt a filesystem which is then accessed by the pygrub program, running as root in the dom0 host environment, thus allowing the untrusted user to gain privileged access in the host OS. Thanks to the McAfee AVERT Research group for reporting this issue. Addresses CVE-2007-5497. Signed-off-by: Rafal Wojtczuk <rafal_wojtczuk@mcafee.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
2005-01-05dupfs.c (ext2fs_dup_handle): Make sure the new filesystem handleTheodore Ts'o1-1/+7
has its own copy of the orig_super data structure. (This is a better way of fixing a double-free problem in resize2fs which Fedora attempted to fix in e2fsprogs-1.35-double_free.patch. Addresses Red Hat Bugzilla #132707.)

all now take a 'void *' instead of a 'void **' in order to avoid pointer aliasing problems with GCC 3.x.

inode.c (ext2fs_open_inode_scan): Initialize the group variables so that we don't need to call get_next_blockgroup() the first time around. Saves a bit of time, and prevents us from needing to assign -1 to current_group (which is an unsigned value). icount.c (insert_icount_el): Cast the estimated number of inodes from a float to an ino_t. alloc.c, alloc_tables.c, badlbocks.c, bb_compat.c, bb_inode.c, bitmaps.c, bitops.c, block.c, bmap.c, bmove.c, brel_ma.c, check_desc.c, closefs.c, cmp_bitmaps.c, dblist.c, dblist_dir.c, dir_iterate.c, dirblock.c, dupfs.c, expanddir.c, ext2fs.h, fileio.c, freefs.c, get_pathname.c, getsize.c, icount.c, initialize.c, inline.c, inode.c, irel_ma.c, ismounted.c, link.c, lookup.c, mkdir.c, namei.c, native.c, newdir.c, openfs.c, read_bb.c, read_bb_file.c, rs_bitmap.c, rw_bitmaps.c, swapfs.c, test_io.c, tst_badblocks.c, tst_getsize.c, tst_iscan.c, unix_io.c, unlink.c, valid_blk.c, version.c: If EXT2_FLAT_INCLUDES is defined, then assume all of the ext2-specific header files are in a flat directory. block.c, bmove.c, dirblock.c, fileio.c: Explicitly cast all assignments from void * to be compatible with C++. closefs.c (ext2fs_flush): Add a call to io_channel_flush() to make sure the contents of the disk are flushed to disk. dblist.c (ext2fs_add_dir_block): Change new to be new_entry to avoid C++ namespace clash. bitmaps.c (ext2fs_copy_bitmap): Change new to be new_map to avoid C++ namespace clash. ext2fs.h, bb_inode.c, block.c, bmove.c, brel.h, brel_ma.c, irel.h, irel_ma.c, dblist.c, dblist_dir.c, dir_iterate.c, ext2fsP.h, expanddir.c, get_pathname.c, inode.c, link.c, unlink.c: Change private to be priv_data (to avoid C++ namespace clash)

dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more paranoid about validating the directory counts from the block group information. all files: Don't include stdlib.h anymore; include it in ext2_fs.h, since that file requires stdlib.h ChangeLog, Makefile.in, dirinfo.c: dirinfo.c (e2fsck_add_dir_info): Use ext2fs_get_num_dirs instead of e2fsck_get_num_dirs, which has been removed. Makefile.in (PROGS): Remove @EXTRA_PROGS@, since we don't want to compile and install flushb. ChangeLog, configure.in: Remove @EXTRA_PROGS@, since we aren't using it in 2fsck/Makefile.in anymore ChangeLog, Makefile.in: Install debugfs in /sbin, instead of /usr/sbin. libext2fs.texinfo: Update version string to be 1.12 Makefile.in: Fix bug in find script which made the exclusion list, where a '-' was missing from an -name option.
