Fix the following bugs:

2. 'hash_flags' incorrectly uses a __bitwise type.

3. The optstring doesn't contain "c" or "e", so the -c and -e options

5 years agodebugfs: avoid ambiguity when printing filenames
Eric Biggers [Sun, 28 Apr 2019 23:42:41 +0000 (19:42 -0400)]
debugfs: avoid ambiguity when printing filenames

The way debugfs escapes filenames is ambiguous because a sequence like
M-A can mean either the byte 'A' + 128 == 0xc1 or the three bytes
{'M', '-', 'A'}.  Similarly, ^A can mean either the byte
'A' ^ 0x40 == 0x01 or the two bytes {'^', 'A'}.

Fix this and simplify the code by switching to a simpler strategy where
all bytes < 32, all bytes >= 127, and backslash are encoded with C-style
hex escape sequences.  E.g., the byte 0xc1 will now be encoded as \xc1
rather than M-A as it was before, while a filename consisting of the
three bytes {'M', '-', 'A'} will continue to be shown as M-A.

I want to fix this mainly because I want to use debugfs to retrieve raw
encrypted filenames for ciphertext verification tests.  But this doesn't
work if the returned filenames are ambiguous.

create_inode: fix copying large files

When copying large files into a ext filesystem at mkfs time the copy
fails at 2^31 bytes in.  There are two problems:

copy_file_chunk() passes an offset (off_t, 64-bit typically) to
ext2fs_file_lseek() which expects a ext2_off_t (typedef to __u32) so
the value is truncated. Solve by calling ext2fs_file_llseek() which
takes a u64 offset instead.

try_lseek_copy() rounds the data and hole offsets as found by lseek()
to block boundaries, but the calculation gets truncated to 32-bits.
Solve by casting the 32-bit blocksize to off_t to ensure this doesn't
happen.
