* fix integer overflow warning in i2o_blockMeelis Roos2007-07-311-1/+1
| | | | | | | | | | | | | | | | | | drivers/message/i2o/i2o_block.c: In function 'i2o_block_transfer': drivers/message/i2o/i2o_block.c:837: warning: integer overflow in expression msg->u.head[1] = cpu_to_le32(I2O_CMD_PRIVATE << 24 | HOST_TID << 12 | tid); and I2O_CMD_PRIVATE is defined as 0xFF. This gets "0xFF0100 | tid" and fits into 32-bit unsigned but not into 32-bit signed integer properly. Target value is defined as u32 so the claculation does not fit during computation. Change local variable tid to u32 so the whole expression is of u32 type and fits well into u32 result.

* UDF: fix UID and GID mount option ignoranceCyrill Gorcunov2007-07-313-4/+10
| | | | | | | | | | | | | | | | | | | | | | | | | This patch fix weird behaviour of UDF mounting procedure. To get UID changed (for now) we have to type mount -t udf -o uid=some_user,uid=ignore /dev/device /mnt/moun_point and specifying two uid at once is strange a bit. So with the patch we are able to mount without additional 'uid=ignore' option. The same for GID option is done. This patch will not break current mount scheme (with two option). Btw this does fix (I hope) the following [BUG 6124] mount of UDF fs ignores UID and GID options http://bugzilla.kernel.org/show_bug.cgi?id=6124 Signed-off-by: Cyrill Gorcunov <gorcunov@gmail.com> Cc: Jan Kara <jack@ucw.cz> Cc: Michael <auslands-kv@gmx.de> Cc: Eric Sandeen <sandeen@redhat.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* Fix a use after free bug in kernel->userspace relay file supportJesper Juhl2007-07-311-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Coverity spotted what looks like a real possible case of using a variable after it has been freed. The problem is in kernel/relay.c::relay_open_buf() If the code hits "goto free_buf;" it ends up in this code : free_buf: relay_destroy_buf(buf); <--- calls kfree() on 'buf'. free_name: kfree(tmpname); end: return buf; <-- use after free of 'buf'. I read through the callers and they all handle a NULL return from this function as an error (and hitting the 'free_buf' label only happens on failure to chan->cb->create_buf_file(), so that looks like a clear error to me). The patch simply sets 'buf' to NULL after the call to relay_destroy_buf(buf); - as far as I can see that should take care of the problem. The patch also corrects a reference to a documentation file while I was at it. Note from Mathieu: the documentation reference change should have been done in a separate patch, but I guess no one will really care.

But this is ok, because kthreadd_setup() is only ever called at init time, and then kthreadd() proceeds into its "for (;;)" loop. We could mark kthreadd __init_refok, but kthreadd_setup() with just one callsite and 4 lines in it (it's been that small since 10ab825bdef8df51) doesn't need to be a separate function at all -- so let's just move those four lines at beginning of kthreadd() itself.

| | | | | | | | | | | | | | | | | | This is only called at init time and only happens if the BIOS screws something up, so the leak is slight and it is probably not worth sending to 2.6.22.x. The driver would not initialize the interface in the case, and I have no reports of this happening. I have booted and run tests on a system with this patch. Note that the original patch was munged by the mailer, here's a new one. If we ever hit the "default:" case in the switch in try_init_dmi(), then we'll leak the storage allocated with kzalloc() and assigned to 'info'.

Unfortunately, it doesn't wait for the abort to complete before restarting it which creates a race between the abort and the restart.

* 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.

* AFS: fix file lockingDavid Howells2007-07-311-47/+79
| | | | | | | | | | | | | | Fix file locking for AFS: (*) Start the lock manager thread under a mutex to avoid a race. (*) Made the locking non-fair: New readlocks will jump pending writelocks if there's a readlock currently granted on a file. This makes the behaviour similar to Linux's VFS locking.

* bpqether: fix rcu usagePaul E. McKenney2007-07-311-3/+3
| | | | | | | | | | | | | | | The rcu_dereference() primitive needs to be applied to an l-value in order to ensure that compiler writers don't get an opportunity to apply reordering optimizations that could result in multiple fetches or in other misbehavior. This patch pulls the rcu_dereference() calls in bpq_seq_next() up to the point at which the fetched pointers are still l-values, rather than after list_entry() has transformed them into r-values.

* Fix user struct leakage with locked IPC shem segmentPavel Emelianov2007-07-311-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When user locks an ipc shmem segmant with SHM_LOCK ctl and the segment is already locked the shmem_lock() function returns 0. After this the subsequent code leaks the existing user struct: == ipc/shm.c: sys_shmctl() == ... err = shmem_lock(shp->shm_file, 1, user); if (!err) { shp->shm_perm.mode |= SHM_LOCKED; shp->mlock_user = user; } ... == Other results of this are: 1. the new shp->mlock_user is not get-ed and will point to freed memory when the task dies. 2. the RLIMIT_MEMLOCK is screwed on both user structs. The exploit looks like this: == id = shmget(...); setresuid(uid, 0, 0); shmctl(id, SHM_LOCK, NULL); setresuid(uid + 1, 0, 0); shmctl(id, SHM_LOCK, NULL); == My solution is to return 0 to the userspace and do not change the segment's user.
