If the directory is packed with no slack space, as soon as any new
directory entries are added, leaf nodes end up getting split and
directory ends up getting very inefficient.

If a block device is read-only, e2fsck -p gets into an infinite loop
trying to preenhalt, closing and flushing the fs, which tries to flush
the cache, which gets a write error and calls preenhalt which tries to
close and flush the fs ... ad infinitum.
Per Ted's suggestion just flag the ctx as "exiting" and short-circuit
the infinite loop.
Tested by running e2fsck -p on a block device set read-only by BLKROSET.

Factor out code to clear a bogus inode and update e2fsck's internal

If the primary superblock differs from the backup superblock in
certain key respects, force a full check (if e2fsck was invoked in

filesystem was opened in read/write mode, then write the primary
superblock to all of the backups.

The Linux floppy driver is a bit different from the other block device
drivers, in that if the device has been opened with O_EXCL, it disallows
another open(), even if the second open() does not have the O_EXCL flag.
So this patch moves the call to ext2fs_get_device_size() so that if it
returns EBUSY, e2fsck can close the filesystem, retry the device size,
and then reopen it. This rather complicated approach is required since
we need to know the blocksize of the filesystem before we can call
ext2fs_get_device_size().

Change the iterator abstraction and replace e2fsck_get_dir_info() with

E2F_FLAG_RESTARTED. This fixes a bug where if the user

but since this is dangerous, it's not allowed in the problem code
table.

sequence number to a random value to avoid recovering bad transactions

Since only the master superblock is written during a restart, force
that superblock to be used after a restart; otherwise changes to the

the progress bar, and SIGUSR2 will disable the progress bar. This is

f_recnect_bad: New test which checks the case where a disconnect inode

progress updates so that callers can keep track of the completion
progress of e2fsck. Designed for use by progress, except for -C 0,
which prints a spinning report which may be useful for some users.

EXT2_IOC_GETVERSION ioctl.
unix.c: Fix bug in check of feature set, to make sure we can really
fix this filesystem.
problem.h: Make blkcount type to be of type blkcnt_t. Make the num
field be a 64 bit type. Add the problem code PR_1_FEATURE_LARGE_FILES
problem.c: Add table entry for the problem code PR_1_FEATURE_LARGE_FILES.
pass1.c (e2fsck_pass1): A non-zero i_dir_acl field is only a problem

are no large_files, then clear the LARGE_FLAG feature flag. If there
are large_files, but the LARGE_FLAG feature flag is not set, complain
and offer to fix it.
(check_blocks): Add support to deal with non-directory inodes that
have i_size_high set (i.e., large_files). Don't give an error if a
directory has preallocated blocks, to support the DIR_PREALLOC
feature.
(process_block, process_bad_block): The blockcnt variable is a type of
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

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.

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: Add new field, priv_data to the e2fsck context structure.
It should be used by callers of the e2fsck functions only, and not by
anything in e2fsck itself.
super.c: Instead of call ext2fs_get_device_size(), define and call
e2fsck_get_device_size(). (This function may be stubbed out in
special versions of e2fsck.)
pass3.c, pass4.c: Remove extra calls to the progress function that
weren't needed.
mke2fs.8.in: Update man page to note that the format of the bad block
file is the same as the one generated by badblocks.
dirinfo.c, e2fsck.c: Don't include com_err.h; it isn't needed.
e2fsck.h: Include <time.h> since it is needed
super.c: If EXT2_SKIP_UUID is defined, then skip the UUID processing.
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, 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

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,

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.
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.
