11 years agomissing bits of net-namespace / sysctl
Al Viro [Sun, 27 Jul 2008 07:59:33 +0000]
missing bits of net-namespace / sysctl

Piss-poor sysctl registration API strikes again, film at 11...

What we really need is _pathname_ required to be present in already
registered table, so that kernel could warn about bad order.  That's the
next target for sysctl stuff (and generally saner and more explicit
order of initialization of ipv[46] internals wouldn't hurt either).

For the time being, here are full fixups required by ..._rotable()
stuff; we make per-net sysctl sets descendents of "ro" one and make sure
that sufficient skeleton is there before we start registering per-net
sysctls.

11 years agoALSA: Allow to force model to intel-mac-v3 in snd_hda_intel (sigmatel).
Nicolas Boichat [Mon, 21 Jul 2008 14:18:01 +0000]
ALSA: Allow to force model to intel-mac-v3 in snd_hda_intel (sigmatel).

Currently, even if you pass model=intel-mac-v3 as a module parameter to
snd_hda_intel, the function patch_stac922x (patch_sigmatel.c) will still
try to auto-detect the model type. This is a problem on my MacBook Pro 1st
generation, which needs intel-mac-v3, but sometimes incorrectly reports
0x00000100 as subsystem id, which causes the switch in patch_stac922x to
select intel-mac-v4.

To fix this, I added a new model called intel-mac-auto, so in case no
module parameter is passed, and an Intel Mac board is detected, the
model will be automatically detected, while no detection will be done
if the model is forced to intel-mac-v3.

This problem has been around for quite a while, and I used to fix it
by moving the case statement for 0x00000100 in patch_stac922x so that
intel-mac-v3 is chosen.

Another way to fix the problem would be to check if a module parameter
was set directly in patch_stac922x, using something like this:
if (spec->board_config == STAC_INTEL_MAC_V3 &&
!codec->bus->modelname) {

But I think it is less elegant (if you prefer that way, I can prepare a
patch).

[PATCH] dup3 fix

Al Viro notice one cornercase that the new dup3() code.  The dup2()
function, as a special case, handles dup-ing to the same file
descriptor.  In this case the current dup3() code does nothing at
all.  I.e., it ingnores the flags parameter.  This shouldn't happen,
the close-on-exec flag should be set if requested.

In case the O_CLOEXEC bit in the flags parameter is not set the
dup3() function should behave in this respect identical to dup2().
This means dup3(fd, fd, 0) should not actively reset the c-o-e
flag.

The patch below implements this minor change.

[patch 4/4] vfs: immutable inode checking cleanup

Move the immutable and append-only checks from chmod, chown and utimes
into notify_change().  Checks for immutable and append-only files are
always performed by the VFS and not by the filesystem (see
permission() and may_...() in namei.c), so these belong in
notify_change(), and not in inode_change_ok().

[patch 3/4] fat: dont call notify_change

The FAT_IOCTL_SET_ATTRIBUTES ioctl() calls notify_change() to change
the file mode before changing the inode attributes.  Replace with
explicit calls to security_inode_setattr(), fat_setattr() and
fsnotify_change().

This is equivalent to the original.  The reason it is needed, is that
later in the series we move the immutable check into notify_change().
That would break the FAT_IOCTL_SET_ATTRIBUTES ioctl, as it needs to
perform the mode change regardless of the immutability of the file.

[patch 05/14] hpfs: dont call permission()

hpfs_unlink() calls permission() prior to truncating the file.  HPFS
doesn't define a .permission method, so replace with explicit call to
generic_permission().

This is equivalent, except that devcgroup_inode_permission() and
security_inode_permission() are not called.

The truncation is just an implementation detail of the unlink, so
these security checks are unnecessary.

I suspect that even calling generic_permission() is unnecessary, since
we shouldn't mind if the file isn't writable.  But I leave that to the
maintainer to decide.

Al Viro [Tue, 15 Jul 2008 10:33:31 +0000]
[PATCH] sysctl: keep track of tree relationships

In a sense, that's the heart of the series.  It's based on the following
property of the trees we are actually asked to add: they can be split into
stem that is already covered by registered trees and crown that is entirely
new.  IOW, if a/b and a/c/d are introduced by our tree, then a/c is also
introduced by it.

That allows to associate tree and table entry with each node in the union;
while directory nodes might be covered by many trees, only one will cover
the node by its crown.  And that will allow much saner logics for /proc/sys
in the next patches.  This patch introduces the data structures needed to
keep track of that.

When adding a sysctl table, we find a "parent" one.  Which is to say,
find the deepest node on its stem that already is present in one of the
tables from our table set or its ancestor sets.  That table will be our
parent and that node in it - attachment point.  Add our table to list
anchored in parent, have it refer the parent and contents of attachment
point.  Also remember where its crown lives.

succeeds if and only if it hadn't entered unregistration yet.  If it
succeeds, we can use it in all normal ways until we release the "use"

->unregistering become non-NULL in all cases when one starts to unregister
the sucker.
* keep pointers to ctl_table entries; they *can* be freed if
the entire thing is unregistered.  However, if ctl_head_grab() succeeds,
we know that unregistration had not happened (and will not happen until
ctl_head_finish()) and such pointers can be used safely.

IOW, now we can have inodes under /proc/sys keep references to ctl_table
entries, protecting them with references to ctl_table_header and
grabbing the latter for the duration of operations that require access
to ctl_table.  That won't cause deadlocks, since unregistration will not
be stopped by mere keeping a reference to ctl_table_header.

[PATCH] beginning of sysctl cleanup - ctl_table_set

New object: set of sysctls [currently - root and per-net-ns].
Contains: pointer to parent set, list of tables and "should I see this set?"
method (->is_seen(set)).
Current lists of tables are subsumed by that; net-ns contains such a beast.
->lookup() for ctl_table_root returns pointer to ctl_table_set instead of
that to ->list of that ctl_table_set.

Miklos Szeredi [Wed, 2 Jul 2008 19:30:15 +0000]
[patch] vfs: fix lookup on deleted directory

Lookup can install a child dentry for a deleted directory.  This keeps
the directory dentry alive, and the inode pinned in the cache and on
disk, even after all external references have gone away.

This isn't a big problem normally, since memory pressure or umount
will clear out the directory dentry and its children, releasing the
inode.  But for UBIFS this causes problems because its orphan area can
overflow.

Fix this by returning ENOENT for all lookups on a S_DEAD directory
before creating a child dentry.

Thanks to Zoltan Sogor for noticing this while testing UBIFS, and
Artem for the excellent analysis of the problem and testing.

For each card successfully added to the bus, create a subdirectory under

At the moment, only a single file is added to the card directory for
all cards: "state". It reflects the "state" field in struct mmc_card,
indicating whether the card is present, readonly, etc.

For MMC and SD cards (not SDIO), another file is added: "status".
Reading this file will ask the card about its current status and
return it. This can be useful if the card just refuses to respond to
any commands, which might indicate that the card state is not what the
MMC core thinks it is (due to a missing stop command, for example.)
