1894d6e6ff Add devno comparison for bdevs in device_is_identical(). 2018-12-12 15:07:33 +01:00

1cc722d0cc Simplify device_is_identical. 
If any argument is null return false (with higher
priority than trivial identity check).

Also device_path can't return null if device struct gets
allocated succesfully.

a5a8467993 Use context in debug log messages. 
To use per-context logging even for debug messages
we need to use the same macro as for error logging.

This speed up wipe operation considerably.

1bf5ff3e6e Open files in read-write mode for posix_fallocate.

874c573bd4 Do not allow used block size larger than page size. 
Some filesystems (NFS) returns bogus blocksize (1MB).
Page-size io should always work and avoids increasing IO beyond aligned LUKS header.

12908709bb Resize loop device after fallocate. 
On old systems we have a loop mapped so the loop must be resized as well.

12040570ca Allow to open device without read check. 
In some specific situation we do not want to read the devices
before initialization.

Here it is integrity checking that will produce warning, because
the device is not yet initialized.

Used only in wipe function (here we must use direct-io anyway)
and expect the device is capable of direct-io.

and also to initialize integrity based device (to reset checksum).

d7a224e47a Disable DIRECT_IO for LUKS header with unaligned keyslots. 
Fixes issue#287.

Such a header is very rare, it is not worth to do more detection here.

8e4e898ce5 Fix device_block_size_fd to return bsize correctly incase of files. 
This patch is for issue #287

In the code for returning block size ( device_block_size_fd in lib/utils_device.c ),
always returns zero in case of files and device_read_test is not executed.

This patch is to fix device_block_size_fd to return block size correctly incase of files.

3adfe80601 Test device read only once for O_DIRECT.

0bc437d92c Detect if O_DIRECT is usable on device allocation. 
Try to read the first sector of a device when allocating
device context.

Should fix issue#247.

31a4d552a2 Support keyfile offset and keyfile size option even for plain volumes. 
For historic reasons, in the plain mode the hashing is not used
if keyfile is used (with exception of --key-file=-).

Print warning if the parameters are ignored.

For other cases, uses keyfile offset, keyfile size and hash
as psecified on commandline.

Partially fixes issue#243

6190ad928d Support device/file images if O_DIRECT cannot be used (1.5.1). 
On some filesystems (like tmpfs) O_DIRECT cannot be used.
So just try to open device without O_DIRECT in the second try.
