A misunderstanding C's precedence rules and the meaning of

pass1 was checking that an "extent's" start+len did not extend

Extent data is shared with the i_block[] space in the inode,
but it is always swapped on access, not when the inode is read.
In e2fsck/pass1.c we must be careful when checking validity
of the extents flag on the inode. If the flag was set when
the inode was read & swapped, then the extents data itself
(in ->i_block[]) was NOT swapped, so testing for a valid
extent header requires some swapping first. Then, if we
ultimately set the extents flag, all of i_block[] must be
re/un-swapped.
This passes the f_extent regression test on both ppc & x86.

blkcnt_t, for conversion to the new block_iterate2.
pass2.c (process_bad_inode): A non-zero i_dir_acl field is only a
problem for directory inodes. (Since it is also i_size_high now.)
message.c (expand_inode_expression): Print a 64-bits of the inode size
for non-directory inodes. (Directory inodes can only use a 32-bit
directory acl size, since i_size_high is shared with i_dir_acl.) Add
sanity check so that trying to print out the directory acl on a
non-directory inode will print zero. (expand_percent_expression): %B
and %N, which print pctx->blkcount and pctx->num, can now be 64 bit
variables. Print them using the "%lld" format if EXT2_NO_64_TYPE is
not defined.
e2fsck.h: Add the large_flagsfield to the e2fsck context.
e2fsck.c (e2fsck_reset_context): Clear the large_flags field.
ChangeLog, expect.1:
f_messy_inode: Modify test to deal with changes to support 64-bit size
files. (/MAKEDEV had i_dir_acl, now i_size_high, set.)
e2fsck.c (e2fsck_run): Since E2F_FLAG_SIGNAL_MASK doesn't
include EXT2_FLAG_RESTART anymore, we need to adjust this
routine so that it *does* return in the case of it seeing
EXT2_FLAG_RESTART.
pass1.c (e2fsck_pass1): ext2_get_next_inode() may call the group done
callback function, which may set context abort flags. So we need to
test the context abort flags after we call ext2_get_next_inode().
(process_inodes): If we abort due out of process_inodes, do a clean
exit by breaking out of the for loop instead of just returning.
e2fsck.h (E2F_FLAG_SIGNAL_MASK): EXT2_FLAG_RESTART shouldn't be
considered a SIGNAL mask (i.e., requiring an immediate abort of
processing to restart). FLAG_RESTART just means that we want to
restart once pass 1 is complete.
Change the progress function to return an integer; if returns 1, then
the progress function is expected to have set the e2fsck context flag
signalling a user abort, and the caller should also initiate a user
abort.
e2fsck.h: If EXT2_FLAT_INCLUDES is defined, then assume all of
the ext2-specific header files are in a flat directory.
dirinfo.c, ehandler.c, pass1.c, pass1b.c, pass2.c, pass5.c,
super.c, swapfs.c, unix.c: Explicitly cast all assignments
from void * to be compatible with C++.
unix.c (sync_disk): Remove sync_disk and calls to that function,
since ext2fs_close() now takes care of this.
pass1.c, pass1b.c, pass2.c, pass3.c, swapfs, badblocks.c,
ehandler.c, unix.c: Change use of private to be priv_data, to
avoid C++ reserved name clash.
pass1.c (e2fsck_pass1_check_device_inode): For now, only check to make
sure the extra i_blocks in a device are cleared if the immutable flag
is set.
util.c (print_resource_track): Fix typo which caused the time/resource
tracking to print "Pass 1 :" instead of "Pass 1: ".
version.h:
Change version to 1.12-WIP, in preparation for an e2fsprogs 1.12 release.
Fix bug where first_block wasn't getting incremented, which caused
user to get a "Programming error?" warning if there was a bad block in
a non-primary superblock/group_descriptor. Also fixed another bug so
that ext2fs_bg_has_super() is consulted, to avoid problems when using
a filesystem with the sparse_groups option set and there are bad
blocks at the beginning of a group which doesn't have a superblock.
pass1.c, pass2.c, pass3.c, pass4.c, pass5.c: Add calls to the progress
indicator function.
pass1.c (scan_callback): Add call to the progress feedback function
(if it exists).
super.c (check_super_block): Skip the device size check if the
get_device_size returns EXT2_EXT_UNIMPLEMENTED.
iscan.c (main): Don't use fatal_error() anymore.
pass1b.c, swapfs.c, badblocks.c: Set E2F_FLAG_ABORT instead of calling
fatal_error(0).
problem.c, pass3.c (PR_3_ROOT_NOT_DIR_ABORT,
PR_3_NO_ROOT_INODE_ABORT): New problem codes.
problem.c, pass2.c (PR_2_SPLIT_DOT): New problem code.
problem.c, pass1.c (PR_1_SUPPRESS_MESSAGES): New problem code.
problemP.h: New file which separates out the private fix_problem data
structures.
util.c, dirinfo.c, pass1.c, pass1b.c, pass2.c, pass5.c, super.c,
swapfs.c util.c: allocate_memory() now takes a e2fsck context as its
first argument, and rename it to be e2fsck_allocate_memory().
problemP.h:
New file which contains the private problem abstraction definitions.
Makefile.pq:
Remove include of MAKEFILE.STD, which doesn't exist at this point.
Change ext2fs_read_inode, ext2fs_write_inode to take the e2fsck
context as their first argument.
Change dir_info.c routines to take an e2fsck_context, renamed them to
start with e2fsck_ to avoid namespace issues, and changed them to
store the directory information inside the e2fsck context.
Added e2fsck_run() which calls all of the e2fsck passes in the correct
order, and which handles the return of abort codes.
Added abort processing, both via setjmp/longjmp and via flags in the
e2fsck context.
Use a flag in the e2fsck context instead of the restart_e2fsck global
variable.
Change uses of free and malloc to ext2fs_free_mem and ext2fs_get_mem.
Rename new error codes to _ET_ in them for consistency.
ChangeLog, et_c.awk, et_h.awk:
Remove support for non STDC compilers, since the workarounds caused
problems with the header file.
Makefile.pq:
Checkpoint of powerquest work.
alloc.c (ext2fs_alloc_block): New function which allocates a
block and updates the filesystem accounting records
appropriately.
ext2_err.et.in: Added new error codes: EXT2_NO_MEMORY,
EXT2_INVALID_ARGUMENT, EXT2_BLOCK_ALLOC_FAIL, EXT2_INODE_ALLOC_FAIL,
EXT2_NOT_DIRECTORY
Change various library files to use these functions instead of EINVAL,
ENOENT, etc.
ChangeLog, pass1.c, pass3.c:
pass3.c (get_lost_and_found): Check error return of
EXT2_FILE_NOT_FOUND instead of ENOTDIR
pass1.c (pass1_check_directory): Return EXT2_NO_DIRECTORY instead of
ENOTDIR
expect.icount:
Change expected error string to be "Invalid argument passed to ext2 library"
instead of just "Invalid argument"
pass*.c, super.c: Massive changes to avoid using printf and com_err
routines. All diagnostic messages are now routed through the
fix_problem interface.
pass2.c (check_dir_block): Check for duplicate '.' and '..' entries.
problem.c, problem.h: Add new problem codes PR_2_DUP_DOT and
PR_2_DUP_DOT_DOT.
problem.c: Added new problem codes for some of the superblock
corruption checks, and for the pass header messages. ("Pass
1: xxxxx")
util.c (print_resource_track): Now takes a description argument.
super.c, unix.c, e2fsck.c: New files to separate out the
operating-specific operations out from e2fsck.c. e2fsck.c now
contains the global e2fsck context management routines, and
super.c contains the "pass 0" initial validation of the
superblock and global block group descriptors.
pass1.c, pass2.c, pass3.c, pass4.c, pass5.c, util.c: Eliminate
(nearly) all global variables and moved them to the e2fsck
context structure.
problem.c, problem.h: Added new problem codes PR_0_SB_CORRUPT,
PR_0_FS_SIZE_WRONG, PR_0_NO_FRAGMENTS, PR_0_BLOCKS_PER_GROUP,
PR_0_FIRST_DATA_BLOCK
expect.1, expect.2:
Updated tests to align with e2fsck problem.c changes.
message.c: Add compression for the word "Illegal"
problem.c: Added entries for PR_2_BAD_CHAR_DEV and PR_2_BAD_BLOCK_DEV
pass1.c (pass1, check_device_inode), pass2.c (process_bad_inode): Use
a more stringent test for a valid device.
ChangeLog, Makefile.in:
Makefile.in (install): Fix rm command to use $(DESTDIR) appropriately.
pass1.c (mark_table_blocks): Mark the superblock and group descriptor
blocks first, so that any conflicts between these and the bitmap or
inode table blocks is noticed.
problem.c: Fix message printed out when a block or inode bitmap
conflicts with other fs data, has the correct group number in it.
