2*6a54128fSAndroid Build Coastguard Worker==================================
3*6a54128fSAndroid Build Coastguard Worker
4*6a54128fSAndroid Build Coastguard WorkerFixed a bug in debugfs where an error messages weren't getting printed
5*6a54128fSAndroid Build Coastguard Workerwhen the ext2 library routines to read inodes returned errors in the
6*6a54128fSAndroid Build Coastguard Workerstat, cmri and rm commands.
7*6a54128fSAndroid Build Coastguard Worker
8*6a54128fSAndroid Build Coastguard WorkerFixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
9*6a54128fSAndroid Build Coastguard Workerprovided, it won't create an inode table smaller than the minimum
10*6a54128fSAndroid Build Coastguard Workernumber of inodes required for a proper ext2 filesystem.
11*6a54128fSAndroid Build Coastguard Worker
12*6a54128fSAndroid Build Coastguard WorkerFsck now parses the /etc/fstab file directly (instead of using
13*6a54128fSAndroid Build Coastguard Workergetmntent()), so that it can distinguish between a missing pass number
14*6a54128fSAndroid Build Coastguard Workerfield and pass number field of zero.  This caused problems for
15*6a54128fSAndroid Build Coastguard Workerdiskless workstations where all of the filesystems in /etc/fstab have
16*6a54128fSAndroid Build Coastguard Workeran explicit pass number of zero, and fsck could not distinguish this
17*6a54128fSAndroid Build Coastguard Workerfrom a /etc/fstab file with missing pass numbers.
18*6a54128fSAndroid Build Coastguard Worker
19*6a54128fSAndroid Build Coastguard WorkerE2fsck will create a /lost+found directory if there isn't one in the
20*6a54128fSAndroid Build Coastguard Workerfilesystem, since it's safer to create the lost+found directory before
21*6a54128fSAndroid Build Coastguard Workerit's needed.
22*6a54128fSAndroid Build Coastguard Worker
23*6a54128fSAndroid Build Coastguard WorkerFixed e2fsck so that it would detect bogus immutable inodes which
24*6a54128fSAndroid Build Coastguard Workerhappen to be sockets and FIFO files, and offer to clear them.
25*6a54128fSAndroid Build Coastguard Worker
26*6a54128fSAndroid Build Coastguard WorkerIf a filesystem has multiple reasons why it needs to be checked, and
27*6a54128fSAndroid Build Coastguard Workerone of the reasons is that it is uncleanly mounted, e2fsck will print
28*6a54128fSAndroid Build Coastguard Workerthat as the reason why the filesystem is being checked.
29*6a54128fSAndroid Build Coastguard Worker
30*6a54128fSAndroid Build Coastguard WorkerCleaned up the output routines of mke2fs so that it doesn't overflow
31*6a54128fSAndroid Build Coastguard Workeran 80 column display when formatting really big filesystems.
32*6a54128fSAndroid Build Coastguard Worker
33*6a54128fSAndroid Build Coastguard WorkerAdded a sanity check to e2fsck to make sure that file descriptors 0,
34*6a54128fSAndroid Build Coastguard Worker1, 2 are open before opening the hard disk.  This avoids a problem
35*6a54128fSAndroid Build Coastguard Workerwhere a broken program might exec e2fsck with those file descriptors
36*6a54128fSAndroid Build Coastguard Workerclosed, which would cause disastrous results if the kernel returns a
37*6a54128fSAndroid Build Coastguard Workerfile descriptor for the block device which is also used by FILE *
38*6a54128fSAndroid Build Coastguard Workerstdout.
39*6a54128fSAndroid Build Coastguard Worker
40*6a54128fSAndroid Build Coastguard WorkerFixed up the e2fsck progress reporting functions so that the values
41*6a54128fSAndroid Build Coastguard Workerreliably reach 100% at the completion of all of the e2fsck passes.
42*6a54128fSAndroid Build Coastguard Worker
43*6a54128fSAndroid Build Coastguard WorkerFixed minor documentation bugs in man pages and usage messages.

45*6a54128fSAndroid Build Coastguard WorkerProgrammer's notes:
46*6a54128fSAndroid Build Coastguard Worker-------------------
47*6a54128fSAndroid Build Coastguard Worker
48*6a54128fSAndroid Build Coastguard WorkerFixed a number of lint warnings in the ext2fs library and potential
49*6a54128fSAndroid Build Coastguard Workerportability problems from other OS's header files that might define
50*6a54128fSAndroid Build Coastguard WorkerCPP macros for names like "max" and "min".
51*6a54128fSAndroid Build Coastguard Worker
52*6a54128fSAndroid Build Coastguard Workerext2fs_badblocks_list_add() has been made more efficient when it needs
53*6a54128fSAndroid Build Coastguard Workerto grow the bad blocks list.
54*6a54128fSAndroid Build Coastguard Worker
55*6a54128fSAndroid Build Coastguard WorkerFixed a bug in e2fsck which caused it to dereference a freed pointer
56*6a54128fSAndroid Build Coastguard Workerjust before exiting.
57*6a54128fSAndroid Build Coastguard Worker
58*6a54128fSAndroid Build Coastguard WorkerFixed the substitution process for generating the mk_cmds and compile_et
59*6a54128fSAndroid Build Coastguard Workerscripts so that they will work outside of the build tree.
60*6a54128fSAndroid Build Coastguard Worker
61*6a54128fSAndroid Build Coastguard WorkerAdd sanity check to e2fsck so that if an internal routine
62*6a54128fSAndroid Build Coastguard Worker(ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
63*6a54128fSAndroid Build Coastguard Workerand causing a core dump.  This should never happen, but...
