o Make the inversion setting specific, ie, only for the 200103A DVB-S This should not be flagged on other cards. o Make the frequency setting card specific o Make the bandwidth setting generic such that it supports more DVB-T cards o Set QAM size for DVB-C cards that do not autodetect QAM size o Fix a bug that caused the polarization not to be set. Set polarization for cards that do not autodetect polarization o Fix a bogus frontend signal lock, that caused a tuning delay as well. o Make the Symbolrate setting card specific Signed-off-by:

The flexcop chip often stops generating interrupts after some hours of operation. Apparently this can be fixed by resetting register block 0x300 at each channel change (this is not detailed in the flexcop data books). This patch also restructures DMA handling and adds a bit of debug code for the irq problem in case it still happens for someone. Signed-off-by:

Dcookies shouldn't play with the internals of dentry and vfsmnt refcounting. It defeats grepping, and is prone to break if implementation details change. In addition the function doesn't even seem to be performance critical: it calls kmem_cache_alloc(). Signed-off-by:

This patch sets ->mnt_namespace where it's actually added to the namespace. Previously mnt_namespace was set in do_kern_mount() even if the filesystem was never added to any process's namespace (most kernel-internal filesystems). This discrepancy doesn't actually cause any problems, but it's cleaner if mnt_namespace is NULL for these non exported filesystems. Signed-off-by:

This patch clears mnt_namespace in an expired mount. If mnt_namespace is not cleared, it's possible to attach a new mount to the already detached mount, because check_mnt() can return true. The effect is a resource leak, since the resulting tree will never be freed. Signed-off-by:

This patch fixes a bug noticed by Al Viro: However, we still have a problem here - just what would happen if vfsmount is detached while we were grabbing namespace semaphore? Refcount alone is not useful here - we might be held by whoever had detached the vfsmount. IOW, we should check that it's still attached (i.e. that mnt->mnt_parent != mnt). If it's not - just leave it alone, do mntput() and let whoever holds it deal with the sucker. No need to put it back on lists. Signed-off-by:

This patch splits the mark_mounts_for_expiry() function. It's too complex and too deeply nested, even without the bugfix in the following patch. Otherwise code is completely the same. Signed-off-by:

Miklos Szeredi authored
This patch simplifies mark_mounts_for_expiry() by using detach_mnt() instead of duplicating everything it does. It should be an equivalent transformation except for righting the dput/mntput order. Al Viro said: "Looks sane". Signed-off-by:

This patch fixes a race found by Ram in mark_mounts_for_expiry() in fs/namespace.c. The bug can only be triggered with simultaneous exiting of a process having a private namespace, and expiry of a mount from within that namespace. It's practically impossible to trigger, and I haven't even tried. But still, a bug is a bug. The race happens when put_namespace() is called by another task, while mark_mounts_for_expiry() is between atomic_read() and get_namespace(). In that case get_namespace() will be called on an already dead namespace with unforeseeable results. The solution was suggested by Al Viro, with his own words: Instead of screwing with atomic_read() in there, why don't we simply do the following: a) atomic_dec_and_lock() in put_namespace() b) __put_namespace() called without dropping lock c) the first thing done by __put_namespace would be struct vfsmount *root = namespace->root; namespace->root = NULL; spin_unlock(...); .... umount_tree(root); ... d) check in mark_... would be simply namespace && namespace->root. And we are all set; no screwing around with atomic_read(), no magic at all. Dying namespace gets NULL ->root. All changes of ->root happen under spinlock. If under a spinlock we see non-NULL ->mnt_namespace, it won't be freed until we drop the lock (we will set ->mnt_namespace to NULL under that lock before we get to freeing namespace). If under a spinlock we see non-NULL ->mnt_namespace and ->mnt_namespace->root, we can grab a reference to namespace and be sure that it won't go away.

This patch clears mnt_namespace on unmount. Not clearing mnt_namespace has two effects: 1) It is possible to attach a new mount to a detached mount, because check_mnt() returns true. This means, that when no other references to the detached mount remain, it still can't be freed. This causes a resource leak, and possibly un-removable modules. 2) If mnt_namespace is dereferenced (only in mark_mounts_for_expiry()) after the namspace has been freed, it can cause an Oops, memory corruption, etc. 1) has been tested before and after the patch, 2) is only speculation.
