* libblkid: use correct block size for UDF probeZachary Catlin2013-03-021-15/+30
| | | | | | | | | | | In UDF, Volume Structure Descriptors are always 2048 bytes long (ECMA-167, 3rd ed., §2/9.1), while filesystem sectors are the same size as the sectors of the underlying media (e.g., UDF 2.01 §1.3.2). Before this commit, the block size was estimated from VSD offsets, which gives incorrect answers for non-optical media. Now, the UDF probe uses the device block size by default, falling back to 2048-byte sectors for the case of optical-disk images. Signed-off-by: Zachary Catlin <z@zc.is>

* libblkid: Probe UDF volumes for ISO9660 info as wellZeeshan Ali (Khattak)2013-02-144-2/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I have seen blkid failing to report any meaningful data on some of UDF volumes I have (Windows installer media): $ ./blkid -p -o udev en_windows_7_professional_with_sp1_x64_dvd_u_676939.iso ID_FS_LABEL=UDF_Volume ID_FS_LABEL_ENC=UDF\x20Volume ID_FS_TYPE=udf Also, once my patches to expose more of ISO9660 info get merged, we'd also need the same info to be exposed for UDF volumes. This patch adds ISO9660 probing to UDF volumes and here is the result I see on my example UDF volume (together with my pending patch to expose more ISO9660 information): $ ./blkid -p -o udev en_windows_7_professional_with_sp1_x64_dvd_u_676939.iso ID_FS_PUBLISHER_ID=MICROSOFT CORPORATION ID_FS_APPLICATION_ID=CDIMAGE 2.54 (01/01/2005 TM) ID_FS_UUID=2011-04-12-02-38-58-00 ID_FS_UUID_ENC=2011-04-12-02-38-58-00 ID_FS_BOOT_SYSTEM_ID=EL TORITO SPECIFICATION ID_FS_LABEL=GSP1RMCPRXFRER_EN_DVD ID_FS_LABEL_ENC=GSP1RMCPRXFRER_EN_DVD ID_FS_TYPE=iso9660 $ ./blkid -p -o udev en_windows_xp_professional_with_service_pack_3_x86_cd_x14-80428.iso ID_FS_PUBLISHER_ID=MICROSOFT CORPORATION ID_FS_APPLICATION_ID=CDIMAGE 2.52 (03/09/2004 TM) ID_FS_UUID=2008-04-14-12-00-00-00 ID_FS_UUID_ENC=2008-04-14-12-00-00-00 ID_FS_BOOT_SYSTEM_ID=EL TORITO SPECIFICATION ID_FS_LABEL=GRTMPFPP_EN ID_FS_LABEL_ENC=GRTMPFPP_EN ID_FS_TYPE=iso9660 Before anyone asks, Yes!

* libblkid: Expose more ISO9660 headersZeeshan Ali (Khattak)2013-02-146-9/+126
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to kill libosinfo's infamous udev rule[1], we need to make blkid report the following information as udev properties on IS09660 media so that libosinfo can make use of that for detection: 1. Volume ID (already exposed as label). 2. System ID. 3. Publisher ID. 4. Application ID. 5. Boot record's boot system ID, (almost always 'EL TORITO SPECIFICATION' if boot record is present). Example use: $ blkid -p -o udev Fedora-17-x86_64-DVD.iso ID_FS_SYSTEM_ID=LINUX ID_FS_APPLICATION_ID=GENISOIMAGE ISO 9660/HFS FILESYSTEM CREATOR (C) 1993 E.YOUNGDALE ID_FS_UUID=2012-05-22-20-55-32-00 ID_FS_UUID_ENC=2012-05-22-20-55-32-00 ID_FS_BOOT_SYSTEM_ID=EL TORITO SPECIFICATION ID_FS_LABEL=Fedora_17_x86_64 ID_FS_LABEL_ENC=Fedora\x2017\x20x86_64 ID_FS_TYPE=iso9660 ID_PART_TABLE_TYPE=dos [1] https://fedorahosted.org/libosinfo/ticket/1 [kzak@redhat.com: - add blkid_ltrim_whitespace() and use it together with blkid_rtrim_whitespace() to trim white spaces - enlarge blkid values to 128 bytes - add generic blkid_probe_set_id_label() function - always terminate all _ID with \0 - don't export the _IDs to blkid cache] Signed-off-by: Karel Zak <kzak@redhat.com>

* libblkid: make blkid_new_probe_from_filename() usable on whole-diskKarel Zak2013-02-061-0/+2
| | | | | | | | | | | | | | | | | This is stupid bug, when libblkid probe for partition table on whole-disk device with old 0.90 Linux RAID then it creates clone of the struct blkid_probe to avoid collisions with the original probing setting. If the cloned prober is unnecessary then it's deallocated by blkid_free_probe() ... and this function also closes the file descriptor if the device has been opened by blkid_new_probe_from_filename(). Fortunately we usually use open() + blkid_probe_set_device(), ... except wipefs(1). Reported-by: Lukas Czerner <lczerner@redhat.com> Signed-off-by: Karel Zak <kzak@redhat.com>

* libblkid: add blkid_probe_step_back()Karel Zak2013-02-043-22/+97
| | | | | | | | | | | | | | | | | | | | | | It seems that blkid_do_probe() is too high-level solution for some mkfs programs (for example ext4 mkfs supports "undo" so all write operations has to be implemented by filesystem specific functions). The new function blkid_probe_step_back() resets internal libblkid buffers and move probing stuff one step back. It means that the previously used probing function will be called again in the next blkid_do_probe() call. This allows to modify on-disk data and check for backup superblocks or alternative magic strings. Something like: while (blkid_do_probe(pr) == 0) { ... get SBMAGIC_OFFSET and SBMAGIC len ... ... use your private seek & write() ... blkid_probe_step_back(pr); } References: https://bugzilla.redhat.com/show_bug.cgi?id=902512 Signed-off-by: Karel Zak <kzak@redhat.com>
* libblkid: remove optimization from verify( funrtionKarel Zak2013-02-011-65/+11Star
| | | | | | | | | | | | | | | | Now libblkid (the cache based part) tries to probe for the cached filesystem firstly. This optimization is broken, because: * new another superblock could be on the device and the original is already obsolete * we still need to probe for partitions and raids * the code was too fragile The patch also suggests lsblk --fs in blkid.8 for end users. lsblk read information from used db.

* libblkid: add support for btrfs backup superblockGoffredo Baroncelli2013-01-101-0/+8
| | | | | | | | | | | | | | | | | | Btrfs has three superblock. The first one is placed at 64KB, the second one at 64MB, the third one at 256GB. If the first superblock is valid except that the "magic field" is zeroed, btrfs skips the check of the other superblocks. If the first superblock is fully invalid, btrfs checks for the other superblock. So zeroing the first superblock "magic field" at the beginning seems that the filesystem is wiped. But when the first superblock is overwritten (eg by another filesystem), then the other two superblock may be considered valid, and the filesystem may resurrect. This patch allow to find and wipe the other btrfs superblocks signature. Signed-off-by: Karel Zak <kzak@redhat.com>
