libblkid-tiny: fix f2fs labels by increasing label buffer

2020-01-18T13:43:09Z

f2fs max label length is 1024B (512 * uint16_t) which is way above current 256B used in `struct blkid_struct_probe` which renders labels on f2fs system unusable: $ mkfs.f2fs -l drive /dev/sda1 $ block info /dev/sda1 label buffer too small 1024 > 255 So increase the label buffer again in order to make enough space for f2fs labels.

libblkid-tiny: fix symbol collision with full libblkid

2019-12-22T18:54:42Z

The recent introduction of blkid_new_probe() and blkid_free_probe() in the dynamically linked libblkid-tiny caused the dlopen'd libblkid.so to call into the wrong version of blkid_new_probe() within blkid_new_probe_from_filename(), leading to memory corruption and eventual segmentation faults.

libblkid-tiny: use separated buffer for each block device read

2019-12-20T06:43:15Z

This allows reading multiple chunks of block device data and operating on them simultaneously. Previous implementation was using a single buffer (except for reading more data than allocated size) and subsequent reads were corrupting memory of previously returned buffers. This fixes e.g. problem with reading NTFS UUID and validating VFAT signature. Implementation is based on original libblkid code which handles it similarly. Buffers are put on probe internal list and freed when releasing a probe struct. Signed-off-by: Rafał Miłecki

libblkid-tiny: add functions for allocating & freeing probe struct

2019-12-20T06:43:15Z

This adds blkid_new_probe() and blkid_free_probe() which have to be used in place of simple struct memory allocation. They will allow extending probe struct by any extra initialization code and resources release. Newly introduced probe.c file is based on original libblkid's code. Signed-off-by: Rafał Miłecki

libblkid-tiny: increment label size to 256

2019-07-01T13:53:23Z

Btrfs max label lenght is 255. Increment the blkid_struct_probe struct to respect this new max value. Signed-off-by: Ansuel Smith

libblkid-tiny: remove unused name member

2016-10-17T11:13:47Z

The "name" member of struct blkid_struct_probe is not used anywhere anymore so remove it from the definition to save some stack and heap space. Signed-off-by: Jo-Philipp Wich
