Package: kpartx Version: 0.4.8+git0.761c66f Severity: important Tags: upstream
Hello, kpartx creates wrong partiton mappings for gpt partition tables when the sector size ist not 512 bytes (e.g. 4k exported by an fcal array). This may lead to data corruption when trying to write to the created devices. I have attached a patch fixing the problem. --- gpt.c.orig 2009-08-04 23:34:22.000000000 +0200 +++ gpt.c 2011-06-11 12:09:29.000000000 +0200 @@ -619,6 +619,7 @@ uint32_t i; int n = 0; int last_used_index=-1; + int sector_size_mul = get_sector_size(fd)/512; if (!find_valid_gpt (fd, &gpt, &ptes) || !gpt || !ptes) { if (gpt) @@ -634,9 +635,9 @@ sp[n].size = 0; n++; } else { - sp[n].start = __le64_to_cpu(ptes[i].starting_lba); - sp[n].size = __le64_to_cpu(ptes[i].ending_lba) - - __le64_to_cpu(ptes[i].starting_lba) + 1; + sp[n].start = __le64_to_cpu(ptes[i].starting_lba)*sector_size_mul; + sp[n].size = (__le64_to_cpu(ptes[i].ending_lba) - + __le64_to_cpu(ptes[i].starting_lba) + 1)*sector_size_mul; last_used_index=n; n++; } -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
