* eCryptfs: fix error handling in ecryptfs_initRyusuke Konishi2007-08-111-5/+13
| | | | | | | | | | | | ecryptfs_init() exits without doing any cleanup jobs if ecryptfs_init_messaging() fails. In that case, eCryptfs leaves sysfs entries, leaks memory, and causes an invalid page fault. This patch fixes the problem.

* eCryptfs: fix lookup error for special filesRyusuke Konishi2007-08-111-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | When ecryptfs_lookup() is called against special files, eCryptfs generates the following errors because it tries to treat them like regular eCryptfs files. Error opening lower file for lower_dentry [0xffff810233a6f150], lower_mnt [0xffff810235bb4c80], and flags [0x8000] Error opening lower_file to read header region Error attempting to read the [user.ecryptfs] xattr from the lower file; return value = [-95] Valid metadata not found in header region or xattr region; treating file as unencrypted For instance, the problem can be reproduced by the steps below. # mkdir /root/crypt /mnt/crypt # mount -t ecryptfs /root/crypt /mnt/crypt # mknod /mnt/crypt/c0 c 0 0 # umount /mnt/crypt # mount -t ecryptfs /root/crypt /mnt/crypt # ls -l /mnt/crypt This patch fixes it by adding a check similar to directories and symlinks.

* direct-io: fix error-path crashesBadari Pulavarty2007-08-111-0/+1
| | | | | | | | | | | | | | | | | | | Need to initialize map_bh.b_state to zero. Otherwise, in case of a faulty user-buffer its possible to go into dio_zero_block() and submit a page by mistake - since it checks for buffer_new(). http://marc.info/?l=linux-kernel&m=118551339032528&w=2 akpm: Linus had a (better) patch to just do a kzalloc() in there, but it got lost.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Do not allow cached open for O_RDONLY or O_WRONLY unless the file has been previously opened in these modes. Also Fix the calculation of the mode in nfs4_close_prepare. We should only issue an OPEN_DOWNGRADE if we're sure that we will still be holding the correct open modes. This may not be the case if we've been doing delegated opens. Finally, there is no need to adjust the open mode bit flags in nfs4_close_done(): that has already been done in nfs4_close_prepare().

* isofs: mounting to regular file may succeedKirill Kuvaldin2007-07-311-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It turned out that mounting a corrupted ISO image to a regular file may succeed, e.g. if an image was prepared as follows: $ dd if=correct.iso of=bad.iso bs=4k count=8 We then can mount it to a regular file: # mount -o loop -t iso9660 bad.iso /tmp/file But mounting it to a directory fails with -ENOTDIR, simply because the root directory inode doesn't have S_IFDIR set and the condition in graft_tree() is met: if (S_ISDIR(nd->dentry->d_inode->i_mode) != S_ISDIR(mnt->mnt_root->d_inode->i_mode)) return -ENOTDIR This is because the root directory inode was read from an incorrect block. It's supposed to be read from sbi->s_firstdatazone, which is an absolute value and gets messed up in the case of an incorrect image. In order to somehow circumvent this we have to check that the root directory inode is actually a directory after all.

| | | | | | | | | | | | | | | | A succesful downcall with a negative result (which indicates that the given filesystem is not exported to the given user) should not return an error. Currently mountd is depending on stdio to write these downcalls. With some versions of libc this appears to cause subsequent writes to attempt to write all accumulated data (for which writes previously failed) along with any new data. This can prevent the kernel from seeing responses to later downcalls. Symptoms will be that nfsd fails to respond to certain requests. Signed-off-by: "J.

* fix inode_table test in ext234_check_descriptorsEric Sandeen2007-07-263-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | ext[234]_check_descriptors sanity checks block group descriptor geometry at mount time, testing whether the block bitmap, inode bitmap, and inode table reside wholly within the blockgroup. However, the inode table test is off by one so that if the last block in the inode table resides on the last block of the block group, the test incorrectly fails. This is because it tests the last block as (start + length) rather than (start + length - 1). This can be seen by trying to mount a filesystem made such as: mkfs.ext2 -F -b 1024 -m 0 -g 256 -N 3744 fsfile 1024 which yields: EXT2-fs error (device loop0): ext2_check_descriptors: Inode table for group 0 not in group (block 101)! EXT2-fs: group descriptors corrupted! There is a similar bug in e2fsprogs, patch already sent for that. (I wonder if inside(), outside(), and/or in_range() should someday be used in this and other tests throughout the ext filesystems...)

* make timerfd return a u64 and fix the __put_userDavide Libenzi2007-07-261-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Davi fixed a missing cast in the __put_user(), that was making timerfd return a single byte instead of the full value. Talking with Michael about the timerfd man page, we think it'd be better to use a u64 for the returned value, to align it with the eventfd implementation. This is an ABI change. The timerfd code is new in 2.6.22 and if we merge this into 2.6.23 then we should also merge it into 2.6.22.x. That will leave a few early 2.6.22 kernels out in the wild which might misbehave when a future timerfd-enabled glibc is run on them. mtk says: The difference would be that read() will only return 4 bytes, while the application will expect 8. If the application is checking the size of returned value, as it should, then it will be able to detect the problem (it could even be sophisticated enough to know that if this is a 4-byte return, then it is running on an old 2.6.22 kernel). If the application is not checking the return from read(), then its 8-byte buffer will not be filled -- the contents of the last 4 bytes will be undefined, so the u64 value as a whole will be junk.

* | fallocate syscall interface deficiencyUlrich Drepper2007-07-241-1/+1
|/ | | | | | | | | | | | | | | | | The fallocate syscall returns ENOSYS in case the filesystem does not support the operation and expects the userlevel code to fill in. This is good in concept. The problem is that the libc code for old kernels should be able to distinguish the case where the syscall is not at all available vs not functioning for a specific mount point. As is this is not possible and we always have to invoke the syscall even if the kernel doesn't support it. I suggest the following patch. Using EOPNOTSUPP is IMO the right thing to do.

* x86_64: Avoid too many remote cpu references due to /proc/statRavikiran G Thirumalai2007-07-211-1/+2
| | | | | | | | | | | | | | | | | | | | Too many remote cpu references due to /proc/stat. On x86_64, with newer kernel versions, kstat_irqs is a bit of a problem. On every call to kstat_irqs, the process brings in per-cpu data from all online cpus. Doing this for NR_IRQS, which is now 256 + 32 * NR_CPUS results in (256+32*63) * 63 remote cpu references on a 64 cpu config. /proc/stat is parsed by common commands like top, who etc, causing lots of cacheline transfers This statistic seems useless.

* coda: remove CODA_STORE/CODA_RELEASE upcallsJan Harkes2007-07-213-108/+7
| | | | | | | | | | | | | | | | | | | | | | | This is an variation on the patch sent by Christoph Hellwig which kills file_count abuse by the Coda kernel module by moving the coda_flush functionality into coda_release. However part of reason we were using the coda_flush callback was to allow Coda to pass errors that occur during writeback from the userspace cache manager back to close(). As Al Viro explained on linux-fsdevel, it is impossible to guarantee that such errors can in fact be returned back to the caller. There are many cases where the last reference to a file is not released by the close system call and it is also impossible to pick some close as a 'last-close' and delay it until all other references have been destroyed. The CODA_STORE/CODA_RELEASE upcall combination is clearly a broken design, and it is better to remove it completely.
