[PATCH] Enhancing accessibility of lxdialog

For easily getting fairly good accessibility, the TTY cursor should
always be left at the focus location.  This patch fixes the checklist by
just having the list refreshed after the dialog box (hence the cursor
position remains in the list).

[PATCH] fix non-leader exec under ptrace

This reverts most of commit 30e0fca6c1d7d26f3f2daa4dd2b12c51dadc778a.
It broke the case of non-leader MT exec when ptraced.

13 years ago[PATCH] de_thread: Don't change our parents and ptrace flags.
Eric W. Biederman [Fri, 14 Apr 2006 10:05:55 +0000]
[PATCH] de_thread: Don't change our parents and ptrace flags.

This is two distinct changes.
 - Not changing our real parents.
 - Not changing our ptrace parents.

Not changing our real parents is trivially correct because both tasks
have the same real parents as they are part of a thread group.  Now that
we demote the leader to a thread there is no longer any reason to change
it's parentage.

Not changing our ptrace parents is a user visible change if someone
looks hard enough.  I don't think user space applications will care or
even notice.

In the practical and I think common case a debugger will have attached
to all of the threads using the same ptrace flags.  From my quick skim
of strace and gdb that appears to be the case.  Which if true means
debuggers will not notice a change.

Before this point we have already generated a ptrace event in do_exit
that reports the leaders pid has died so de_thread is visible to a
debugger.  Which means attempting to hide this case by copying flags
around appears excessive.

By not doing anything it avoids all of the weird locking issues between
de_thread and ptrace attach, and removes one case from consideration for
fixing the ptrace locking.

This only addresses Oleg's first concern with ptrace_attach, that of the
problems caused by reparenting.  Oleg's second concern is essentially a
race between ptrace_attach and release_task that causes an oops when we
get to force_sig_specific.  There is nothing special about de_thread
with respect to that race.

[PATCH] do_SAK: Don't recursively take the tasklist_lock

By calling send_sig do_SAK is recursively taking the
tasklist_lock, which is silly.

In addition I just audited the kernel and this was the only
place where tasklist_lock is taken inside of task_lock.

IB/mthca: Fix max_srq_sge returned by ib_query_device for Tavor devices

The driver allocates SRQ WQEs size with a power of 2 size both for
Tavor and for memfree. For Tavor, however, the hardware only requires
the WQE size to be a multiple of 16, not a power of 2, and the max
number of scatter-gather allowed is reported accordingly by the
firmware (and this is the value currently returned by
ib_query_device() and ibv_query_device()).

If the max number of scatter/gather entries reported by the FW is used
when creating an SRQ, the creation will fail for Tavor, since the
required WQE size will be increased to the next power of 2, which
turns out to be larger than the device permitted max WQE size (which
is not a power of 2).

This patch reduces the reported SRQ max wqe size so that it can be used
successfully in creating an SRQ on Tavor HCAs.

Miklos Szeredi [Tue, 11 Apr 2006 19:14:26 +0000]
[fuse] fix deadlock between fuse_put_super() and request_end()

A deadlock was possible, when the last reference to the superblock was
held due to a background request containing a file reference.

Releasing the file would release the vfsmount which in turn would
release the superblock.  Since sbput_sem is held during the fput() and
fuse_put_super() tries to acquire this same semaphore, a deadlock
results.

The chosen soltuion is to get rid of sbput_sem, and instead use the
spinlock to ensure the referenced inodes/file are released only once.
Since the actual release may sleep, defer these outside the locked
region, but using local variables instead of the structure members.

This is a much more rubust solution.

Basically an in-kernel implementation of tee, which uses splice and the
pipe buffers as an intelligent way to pass data around by reference.

Where the user space tee consumes the input and produces a stdout and
file output, this syscall merely duplicates the data inside a pipe to
another pipe. No data is copied, the output just grabs a reference to the
input pipe data.

When nolapic was passed or the local APIC was disabled
for another reason ACPI would still parse the IO-APICs
until these were explicitely disabled with noapic.

Usually this resulted in a non booting configuration unless
"nolapic noapic" was used.

I also disabled the local APIC parsing in this case, although
that's only cosmetic (suppresses a few printks)

sparc32 systems with PCI slots, so it's a bit moot.

The patch gives sparc32 a copy of the sparc64 vga.h.  It fixes sparc32
allmodconfig without mucking up fbdev Kconfig and gives us wider compile
coverage.

We should be shutting down rpciod for the callback channel when we shut down

[PATCH] knfsd: svcrpc: WARN() instead of returning an error from svc_take_page

Every caller of svc_take_page ignores its return value and assumes it
succeeded.  So just WARN() instead of returning an ignored error.  This would
have saved some time debugging a recent nfsd4 problem.

If there are still failure cases here, then the result is probably that we
overwrite an earlier part of the reply while xdr-encoding.

While the corrupted reply is a nasty bug, it would be worse to panic here and
create the possibility of a remote DOS; hence WARN() instead of BUG().

[PATCH] knfsd: nfsd: nfsd_setuser doesn't really need to modify rqstp->rq_cred.

In addition to setting the processes filesystem id's, nfsd_setuser also
modifies the value of the rq_cred which stores the id's that originally came
from the rpc call, for example to reflect root squashing.

There's no real reason to do that--the only case where rqstp->rq_cred is
actually used later on is in the NFSv4 SETCLIENTID/SETCLIENTID_CONFIRM
operations, and there the results are the opposite of what we want--those two
operations don't deal with the filesystem at all, they only record the
credentials used with the rpc call for later reference (so that we may require
the same credentials be used on later operations), and the credentials
shouldn't vary just because there was or wasn't a previous operation in the
compound that referred to some export

This fixes a bug which caused mounts from Solaris clients to fail.

Export a directory that does not exist:
exportfs -orw,fsid=0,insecure,no_subtree_check client:/home/NFS4

Try to mount from client with nfs4. Mount hangs (I'm not sure why -
that's another issue).

While client is hung, back on server

mkdir /home/NFS4

The server panics in dput.  I traced the problem back to svc_export_parse()
calling path_release() even though path_lookup() failed (it happens to fill in
the nameidata structure with a negative dentry - so the test after out:
succeeds).

After patching, an recreating the problem, the client mount still takes some
time before finally exiting with a message "couldn't read superblock".

Here is a simple patch to resolve this issue:

[PATCH] knfsd: nfsd4: fix acl xattr length return

We should be using the length from the second vfs_getxattr, in case it
changed.  (Note: there's still a small race here; we could end up returning
-ENOMEM if the length increased between the first and second call.  I don't
know whether it's worth spending a lot of effort to fix that.)

This makes XFS ACLs usable on NFS exports, which they currently aren't, since
XFS appears to be returning a too-large value for vfs_getxattr() when it's
passed a NULL buffer.  So there's probably an XFS bug here too, though since
getxattr with a NULL buffer is usually used to decide how much memory to
allocate, it may be a fairly harmless bug in most cases.

[PATCH] knfsd: locks: flag NFSv4-owned locks

Use the fl_lmops field to identify which locks are ours, instead of trying to
look them up in our private hash.  This is safer and more efficient.

Earlier versions of this patch used a lock flag instead, but Trond pointed out
that adding a new flag for each lock manager wasn't going to scale well, and
suggested this approach instead; a separate patch converts lockd to using
fl_lmops in the same way.

In the NFSv4 case this looks like a bit of a hack, since the NFSv4 server
isn't currently actually defining a lock_manager_operations struct, so we end
up defining one *just* to serve as a cookie to identify our locks.

But it works, and we actually do expect to start using the
lock_manager_operations at some point anyway.

[PATCH] knfsd: Correct reserved reply space for read requests.

NFSd makes sure there is enough space to hold the maximum possible reply
before accepting a request.  The units for this maximum is (4byte) words.
However in three places, particularly for read request, the number given is
a number of bytes.

This means too much space is reserved which is slightly wasteful.

This is the sort of patch that could uncover a deeper bug, and it is not
critical, so it would be best for it to spend a while in -mm before going
in to mainline.
