We update information in logical volume integrity descriptor after each allocation (as LVID contains free space, number of directories and files on disk etc.). If the filesystem is on some phase change media, this leads to its quick degradation as such media is able to handle only 10000 overwrites or so. We solve the problem by writing new information into LVID only on umount, remount-ro and sync. This solves the problem at the price of longer media inconsistency (previously media became consistent after pdflush flushed dirty LVID buffer) but that should be acceptable. Report by and patch written in cooperation with Rich Coe <Richard.Coe@med.ge.com>. Signed-off-by: NJan Kara <jack@suse.cz>

Anchor block can be located at several places on the medium. Two of the locations are relative to media end which is problematic to detect. Also some drives report some block as last but are not able to read it or any block nearby before it. So let's first try block 256 and if it is all fine, don't look at other possible locations of anchor blocks to avoid IO errors. This change required a larger reorganization of code but the new code is hopefully more readable and definitely shorter. Signed-off-by: NJan Kara <jack@suse.cz>

Make udf_check_valid() return 1 if the validity check passed and 0 otherwise. So far it was the other way around which was a bit confusing. Also make udf_vrs() return loff_t which is really the type it should return (not int). Signed-off-by: NJan Kara <jack@suse.cz>

This patch makes the UDF FS driver use the hardware sector size as the default logical block size, which is required by the UDF specifications. While the previous default of 2048 bytes was correct for optical disks, it was not for hard disks or USB storage devices, and made it impossible to use such a device with the default mount options. (The Linux mkudffs tool uses a default block size of 2048 bytes even on devices with smaller hardware sectors, so this bug is unlikely to be noticed unless UDF-formatted USB storage devices are exchanged with other OSs.) To avoid regressions for people who use loopback optical disk images or who used the (sometimes wrong) defaults of mkudffs, we also try with a block size of 2048 bytes if no anchor was found with the hardware sector size.

Functions udf_CS0toNLS() and udf_NLStoCS0() didn't count with the fact that NLS can return negative length when invalid character is given to it for conversion.

udf_clear_inode() can leave behind buffers on mapping's i_private list (when we truncated preallocation). Call invalidate_inode_buffers() so that the list is properly cleaned-up before we return from udf_clear_inode(). This is ugly and suggest that we should cleanup preallocation earlier than in clear_inode() but currently there's no such call available since drop_inode() is called under inode lock and thus is unusable for disk operations.

Wrap access to task credentials so that they can be separated more easily from the task_struct during the introduction of COW creds. Change most current->(|e|s|fs)[ug]id to current_(|e|s|fs)[ug]id(). Change some task->e?[ug]id to task_e?[ug]id(). In some places it makes more sense to use RCU directly rather than a convenient wrapper; these will be addressed by later patches.

This is a much better version of a previous patch to make the parser tables constant. Rather than changing the typedef, we put the "const" in all the various places where its required, allowing the __initconst exception for nfsroot which was the cause of the previous trouble.

A memory allocation inside alloc_mutex must not recurse back into the filesystem itself because that leads to lock inversion between iprune_mutex and alloc_mutex (and thus to deadlocks - see traces below). alloc_mutex is actually needed only to update allocation statistics in the superblock so we can drop it before we start allocating memory for the inode. tar D ffff81015b9c8c90 0 6614 6612 ffff8100d5a21a20 0000000000000086 0000000000000000 00000000ffff0000 ffff81015b9c8c90 ffff81015b8f0cd0 ffff81015b9c8ee0 0000000000000000 0000000000000003 0000000000000000 0000000000000000 0000000000000000 Call Trace: [<ffffffff803c1d8a>] __mutex_lock_slowpath+0x64/0x9b [<ffffffff803c1bef>] mutex_lock+0xa/0xb [<ffffffff8027f8c2>] shrink_icache_memory+0x38/0x200 [<ffffffff80257742>] shrink_slab+0xe3/0x15b [<ffffffff802579db>] try_to_free_pages+0x221/0x30d [<ffffffff8025657e>] isolate_pages_global+0x0/0x31 [<ffffffff8025324b>] __alloc_pages_internal+0x252/0x3ab [<ffffffff8026b08b>] cache_alloc_refill+0x22e/0x47b [<ffffffff8026ae37>] kmem_cache_alloc+0x3b/0x61 [<ffffffff8026b15b>] cache_alloc_refill+0x2fe/0x47b [<ffffffff8026b34e>] __kmalloc+0x76/0x9c [<ffffffffa00751f2>] :udf:udf_new_inode+0x202/0x2e2 [<ffffffffa007ae5e>] :udf:udf_create+0x2f/0x16d [<ffffffffa0078f27>] :udf:udf_lookup+0xa6/0xad ... kswapd0 D ffff81015b9d9270 0 125 2 ffff81015b903c28 0000000000000046 ffffffff8028cbb0 00000000fffffffb ffff81015b9d9270 ffff81015b8f0cd0 ffff81015b9d94c0 000000000271b490 ffffe2000271b458 ffffe2000271b420 ffffe20002728dc8 ffffe20002728d90 Call Trace: [<ffffffff8028cbb0>] __set_page_dirty+0xeb/0xf5 [<ffffffff8025403a>] get_dirty_limits+0x1d/0x22f [<ffffffff803c1d8a>] __mutex_lock_slowpath+0x64/0x9b [<ffffffff803c1bef>] mutex_lock+0xa/0xb [<ffffffffa0073f58>] :udf:udf_bitmap_free_blocks+0x47/0x1eb [<ffffffffa007df31>] :udf:udf_discard_prealloc+0xc6/0x172 [<ffffffffa007875a>] :udf:udf_clear_inode+0x1e/0x48 [<ffffffff8027f121>] clear_inode+0x6d/0xc4 [<ffffffff8027f7f2>] dispose_list+0x56/0xee [<ffffffff8027fa5a>] shrink_icache_memory+0x1d0/0x200 [<ffffffff80257742>] shrink_slab+0xe3/0x15b [<ffffffff80257e93>] kswapd+0x346/0x447 ...
