| * [PATCH] proc_readfd_common() race fixAl Viro2008-04-22
| | | | | | | | | | | | | | | | Since we drop the rcu_read_lock inside the loop, we can't assume that files->fdt will remain unchanged (and not freed) between iterations. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
| * [PATCH] double-free of inode on alloc_file() failure exit in create_write_pipe()Al Viro2008-04-22

| * [PATCH] lock exclusively in collect_mounts() and drop_collected_mounts()Al Viro2008-04-21
| | | | | | | | | | | | | | | | | | | | Taking namespace_sem shared there isn't worth the trouble, especially with vfsmount ID allocation about to be added. That way we know that umount_tree(), copy_tree() and clone_mnt() are _always_ serialized by namespace_sem. umount_tree() still needs vfsmount_lock (it manipulates hash chains, among other things), but that's a separate story.

| * | dlm: common max length definitionsDavid Teigland2008-04-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | Add central definitions for max lockspace name length and max resource name length. The lack of central definitions has resulted in scattered private definitions which we can now clean up, including an unused one in dlm_device.h. Signed-off-by: David Teigland <teigland@redhat.com>

| * | dlm: recover nodes that are removed and re-addedDavid Teigland2008-04-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a node is removed from a lockspace, and then added back before the dlm is notified of the removal, the dlm will not detect the removal and won't clear the old state from the node. This is fixed by using a list of added nodes so the membership recovery can detect when a newly added node is already in the member list. Signed-off-by: David Teigland <teigland@redhat.com>
| * | dlm: save master info after failed no-queue requestDavid Teigland2008-04-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a NOQUEUE request fails, the rsb res_master field is unnecessarily reset to -1, instead of leaving the valid master setting in place. We want to save the looked-up master values while the rsb is on the "toss list" so that another lookup can be avoided if the rsb is soon reused. The fix is to simply leave res_master value alone.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Fix mapping of blocks using VAT when it is stored in an inode. UDF_I(inode)->i_data already points to the beginning of VAT header so there's no need to add udf_ext0_offset(inode).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements parsing of metadata partitions and reading of Metadata File thus allowing to read UDF 2.50 media. Error resilience is implemented through accessing the Metadata Mirror File in case the data the Metadata File cannot be read. The patch is based on the original patch by Sebastian Manciulea <manciuleas@yahoo.com> and Mircea Fedoreanu <mirceaf_spl@yahoo.com>.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to OSTA UDF specification, only anchor blocks and primary volume descriptors are placed on media relative to the last session. All other block numbers are absolute (in the partition or the whole media). This seems to be confirmed by multisession media created by other systems.

| * | udf: Mount filesystem read-only if it has pseudooverwrite partitionJan Kara2008-04-17
| | | | | | | | | | | | | | | | | | | | | | | | As we don't properly support writing to pseudooverwrite partition (we should add entries to VAT and relocate blocks instead of just writing them), mount filesystems with such partition as read-only. Signed-off-by: Jan Kara <jack@suse.cz>
| * | udf: Handle VAT packed inside inode properlyJan Kara2008-04-17
| | | | | | | | | | | | | | | | | | | | | | | | We didn't handle VAT packed inside the inode - we tried to call udf_block_map() on such file which lead to strange results at best. Add proper handling of packed VAT as we do it with other packed files. Signed-off-by: Jan Kara <jack@suse.cz>
| * | udf: Allow loading of VAT inodeJan Kara2008-04-17
| | | | | | | | | | | | | | | | | | | | | UDF media with VAT could have never worked because udf_fill_inode() didn't know about case FILE_TYPE_VAT20. Fix this. Signed-off-by: Jan Kara <jack@suse.cz>
| * | udf: Fix detection of VAT versionJan Kara2008-04-17
| | | | | | | | | | | | | | | | | | | | | | | | We incorrectly (way to strictly) checked version of VAT on loading and thus refuse to mount correct media. There are just two format versions - below 2.0 and above 2.0 and we understand both. So update the version check accordingly. Signed-off-by: Jan Kara <jack@suse.cz>
| * | udf: Silence warning about accesses beyond end of deviceJan Kara2008-04-17
| | | | | | | | | | | | | | | | | | | | | Some of the computed positions of anchor block could be beyond the end of device. Skip reading such blocks. Signed-off-by: Jan Kara <jack@suse.cz>
| * | udf: Improve anchor block detectionJan Kara2008-04-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | Add <last block>+1 and <last block>-1 to a list of blocks which can be the real last recorded block on a UDF media. Sebastian Manciulea <manciuleas@yahoo.com> claims this helps some drive + media combinations he is able to test. Signed-off-by: Jan Kara <jack@suse.cz>
| * | udf: Cleanup anchor block detection.Jan Kara2008-04-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | UDF anchor block detection is complicated by several things - there are several places where the anchor point can be, some of them relative to the last recorded block which some devices report wrongly. Moreover some devices on some media seem to have 7 spare blocks sectors for every 32 blocks (at least as far as I understand the old code) so we have to count also with that possibility. This patch splits anchor block detection into several functions so that it is clearer what we actually try to do. We fix several bugs of the type "for such and such media, we fail to check block blah" as a result of the cleanup. Signed-off-by: Jan Kara <jack@suse.cz>
| * | udf: Move processing of virtual partitionsJan Kara2008-04-17
| | | | | | | | | | | | | | | | | | | | | | | | This patch move processing of UDF virtual partitions close to the place where other partition types are processed. As a result we now also properly fill in partition access type. Signed-off-by: Jan Kara <jack@suse.cz>

| | | | | | | | | | | | | | | | | | | | | | | | Report error when we fail to allocate memory for a bitmap and properly release allocated memory and inodes for all the partitions in case of mount failure and umount. Signed-off-by: Jan Kara <jack@suse.cz>
| * | udf: Cleanup volume descriptor sequence processingJan Kara2008-04-17
| | | | | | | | | | | | | | | | | | | | | Cleanup processing of volume descriptor sequence so that it is more readable, make code handle errors (e.g. media problems) better. Signed-off-by: Jan Kara <jack@suse.cz>
| * | udf: fix anchor point detectionPavel Emelyanov2008-04-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to ECMA 167 rev. 3 (see 3/8.4.2.1), Anchor Volume Descriptor Pointer should be recorded at two or more anchor points located at sectors 256, N, N - 256, where N - is a largest logical sector number at volume space. So we should always try to detect N on UDF volume before trying to find Anchor Volume Descriptor (i.e. calling to udf_find_anchor()). That said, all this patch does is updates the s_last_block even if the udf_vrs() returns positive value. Originally written and tested by Yuri Per, ported on latest mainline by me.

| * | udf: Remove declarations of arrays of size UDF_NAME_LEN (256 bytes)Jan Kara2008-04-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | There are several places in UDF where we declared temporary arrays of UDF_NAME_LEN bytes on stack. This is not nice to stack usage so this patch changes those places to use kmalloc() instead. Also clean up bail-out paths in those functions when we are changing them.

| * | udf: Remove checking of existence of filename in udf_add_entry()Jan Kara2008-04-17
| | | | | | | | | | | | | | | | | | | | | | | | We don't have to check whether a directory entry already exists in a directory when creating a new one since we've already checked that earlier by lookup and we are holding directory i_mutex all the time. Signed-off-by: Jan Kara <jack@suse.cz>
