* maint: fix shadow declarationSami Kerola2015-01-072-6/+8
| | | | | | | | | | | | | | | | This change fixes all shadow declarations. The worth while to mention fix is with libfdisk sun geometry. It comes from bitops.h cpu_to_be16 macro that further expands from include/bits/byteswap.h that has the shadowing. libfdisk/src/sun.c:961:173: warning: declaration of '__v' shadows a previous local [-Wshadow] libfdisk/src/sun.c:961:69: warning: shadowed declaration is here [-Wshadow] libfdisk/src/sun.c:961:178: warning: declaration of '__x' shadows a previous local [-Wshadow] libfdisk/src/sun.c:961:74: warning: shadowed declaration is here [-Wshadow] That could have caused earlier some unexpected results.

| | | | | | | | | The problem is how fdisk_partition_cmp_start() compare numbers, the function returns result from "a->start - b->start", unfortunately the numbers are uint64, but function returns "int".

* libfdisk: (dos) allow to maximize partitionKarel Zak2014-11-201-25/+96
| | | | | | | | | | | | | | | | | | | | | | | The struct fdisk_partition has special flag "end_follow_default" to make the partition large as much as possible. This patch makes this flag usable for fdisk_set_partition() function. Command line example (enlarge the first partition): # echo ',+' | ./sfdisk -N1 /dev/sdb ... Disk /dev/sdb: 100 MiB, 104857600 bytes, 204800 sectors ... Old situation: Device Boot Start End Sectors Size Id Type /dev/sdb1 2048 22527 20480 10M 83 Linux ^^^^^ New situation: Device Boot Start End Sectors Size Id Type /dev/sdb1 2048 204799 202752 99M 83 Linux ^^^^^^ Signed-off-by: Karel Zak <kzak@redhat.com>

* libfdisk: fix get_partition_unused_primary()Boris Egorov2014-11-141-23/+27
| | | | | | | | | | | | | | | | Was: Mentioned function returns -1 if adding of primary partition is impossible. Caller treats this value as size_t (res variable) and then compares it for negative values, totally ignoring errors. Becomes: Now function takes address to variable and fills it with partition number. Caller treats return value as int and use it appropriately.

* libfdisk: (gpt) don't offer first sector before the first partionKarel Zak2014-11-101-1/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The GPT first usable LBA is usually aligned to grain (1MiB), but for small (<=4MiB) devices we strictly follow sector sizes. In this case there is a small space in front of the aligned begin of the first partition. This useless space should not be offered for the next partitions. Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 32768 bytes Disklabel type: gpt Disk identifier: 041E2D54-AD0C-4C7E-A50D-363D23058D47 Device Start End Size Type /dev/sdb1 40 2087 1M Linux filesystem Command (m for help): n Partition number (2-128, default 2): First sector (34-8158, default 2088): ^^ first usable LBA is 34, but first aligned (recommended) LBA is 40, we use it for the first partition. All this is correct, but the space before the first partition should be ignored. Fixed version: Command (m for help): n Partition number (2-128, default 2): First sector (2088-8158, default 2088): ^^^^ Note this problem does not exist for "normal" (large) devices where first usable LBA is aligned to grain.

* libfdisk: make it possible to use zero for size and startKarel Zak2014-10-1511-176/+272
| | | | | | | | | | | | | | | | The zero may be valid size and start of the partition. This patch introduces: fdisk_partition_has_start() fdisk_partition_has_size() fdisk_partition_unset_size() fdisk_partition_unset_start() to make it possible to work with zero. The feature is internally implemented by magic constant ((type) -1) for undefined sizes and offsets. Signed-off-by: Karel Zak <kzak@redhat.com>
