7812214db6 Add context to device handling functions. 2018-11-27 14:19:57 +01:00

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.

69a844c654 Remove O_SYNC from device open and use fsync(). 
This speed up wipe operation considerably.

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.

248e35036f Do not fail if wipe size is smaller than block size. 
With big page size and image in file this can actually happen.

The command works in this situation but the code will be quite
ineffective (due to blockwise handling).

34bf809e51 Use device alignment wrapper. 
And cache the value to not call ioctl on every block read/write.

3a27c84d98 Rewrite and export crypt_wipe function. 
The crypt_wipe can be used to wipe any part of the device,
and also to initialize integrity based device (to reset checksum).

16fab74ab1 code cleanup related to devfd checks 
alter all checks for devfd value after device_open to
less than zero insted of equals to -1. device_open will
return values different from -1 in case error happens.

In LUKSv1 device_open should always return -1 in case of
error but this check is safer.

The rest is just formating improvement.

54c4b1656f Include sys/sysmacros.h if present. 
Needed for major/minor definitions.

Thanks Mike Frysinger for pointing this out.

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.

65f975655c New device access backend. 
Allocate loop device late (only when real block device needed).
Rework underlying device/file access functions.
Move all device (and ioctl) access to utils_device.c.

Allows using file where appropriate without allocation loop device.

490c17b3cd Fix disk wipe (during keyslot removal) if used on 4k hw block device. 
The "Gutmann" metod uses various offset, direct-io need
to even read device when working with buffer...

Fixes Issue 129.
