d3316ec930 Slight code style improvements for blockwise functions. 2017-04-04 16:04:06 +02:00
Ondrej Kozina
b489b0aa64 Add interrupt safe read_lseek_blockwise function. 2017-04-04 16:03:53 +02:00

2d298071e4 Use read/write buffer functions where appropriate. 2017-04-04 16:03:39 +02:00
Ondrej Kozina
327ebccdb1 Add read_buffer and write_buffer functions. 
Introduce functions for proper I/O handling. These functions
are able to deal with interrupts and partial I/O.

a6c8f974fe Avoid write with zero size. 
This can happen if write buffer size is smaller than underlying
block size and initial buffer is misaligned.

Also use size_t for buffer length variables.

274c417e56 Fixed veritysetup bug with hash offsets bigger than 2gb. 
The lseek in function write_blockwise() could return value
that is greater than integer for result so it can overflow
and fail the whole write.

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.

otherwise use topology values.
