David Meybohm [Mon, 22 Aug 2005 20:11:08 +0000]
[PATCH] preempt race in getppid

With CONFIG_PREEMPT && !CONFIG_SMP, it's possible for sys_getppid to
return a bogus value if the parent's task_struct gets reallocated after
current->group_leader->real_parent is read:

        asmlinkage long sys_getppid(void)
        {
                int pid;
                struct task_struct *me = current;
                struct task_struct *parent;

                parent = me->group_leader->real_parent;
RACE HERE =>    for (;;) {
                        pid = parent->tgid;
        #ifdef CONFIG_SMP
        {
                        struct task_struct *old = parent;

                        /*
                         * Make sure we read the pid before re-reading the
                         * parent pointer:
                         */
                        smp_rmb();
                        parent = me->group_leader->real_parent;
                        if (old != parent)
                                continue;
        }
        #endif
                        break;
                }
                return pid;
        }

If the process gets preempted at the indicated point, the parent process
can go ahead and call exit() and then get wait()'d on to reap its
task_struct. When the preempted process gets resumed, it will not do any
further checks of the parent pointer on !CONFIG_SMP: it will read the
bad pid and return.

So, the same algorithm used when SMP is enabled should be used when
preempt is enabled, which will recheck ->real_parent in this case.

[TCP]: Unconditionally clear TCP_NAGLE_PUSH in skb_entail().

Intention of this bit is to force pushing of the existing
send queue when TCP_CORK or TCP_NODELAY state changes via
setsockopt().

But it's easy to create a situation where the bit never
clears.  For example, if the send queue starts empty:

1) set TCP_NODELAY
2) clear TCP_NODELAY
3) set TCP_CORK
4) do small write()

The current code will leave TCP_NAGLE_PUSH set after that
sequence.  Unconditionally clearing the bit when new data
is added via skb_entail() solves the problem.

[NET]: Fix socket bitop damage

The socket flag cleanups that went into 2.6.12-rc1 are basically oring
the flags of an old socket into the socket just being created.
Unfortunately that one was just initialized by sock_init_data(), so already
has SOCK_ZAPPED set.  As the result zapped sockets are created and all
incoming connection will fail due to this bug which again was carefully
replicated to at least AX.25, NET/ROM or ROSE.

In order to keep the abstraction alive I've introduced sock_copy_flags()
to copy the socket flags from one sockets to another and used that
instead of the bitwise copy thing.  Anyway, the idea here has probably
been to copy all flags, so sock_copy_flags() should be the right thing.
With this the ham radio protocols are usable again, so I hope this will
make it into 2.6.13.

[IPV4]: Fix negative timer loop with lots of ipv4 peers.

From: Dave Johnson <djohnson+linux-kernel@sw.starentnetworks.com>

Found this bug while doing some scaling testing that created 500K inet
peers.

peer_check_expire() in net/ipv4/inetpeer.c isn't using inet_peer_gc_mintime
correctly and will end up creating an expire timer with less than the
minimum duration, and even zero/negative if enough active peers are
present.

If >65K peers, the timer will be less than inet_peer_gc_mintime, and with
>70K peers, the timer duration will reach zero and go negative.

The timer handler will continue to schedule another zero/negative timer in
a loop until peers can be aged.  This can continue for at least a few
minutes or even longer if the peers remain active due to arriving packets
while the loop is occurring.

Bug is present in both 2.4 and 2.6.  Same patch will apply to both just
fine.

[RPC]: Kill bogus kmap in krb5

While I was going through the crypto users recently, I noticed this
bogus kmap in sunrpc.  It's totally unnecessary since the crypto
layer will do its own kmap before touching the data.  Besides, the
kmap is throwing the return value away.

Linus Torvalds [Sat, 20 Aug 2005 01:02:56 +0000]
Fix nasty ncpfs symlink handling bug.

This bug could cause oopses and page state corruption, because ncpfs
used the generic page-cache symlink handlign functions.  But those
functions only work if the page cache is guaranteed to be "stable", ie a
page that was installed when the symlink walk was started has to still
be installed in the page cache at the end of the walk.

We could have fixed ncpfs to not use the generic helper routines, but it
is in many ways much cleaner to instead improve on the symlink walking
helper routines so that they don't require that absolute stability.

We do this by allowing "follow_link()" to return a error-pointer as a
cookie, which is fed back to the cleanup "put_link()" routine.  This
also simplifies NFS symlink handling.

[PATCH] jffs2: fix symlink error handling

The current calling conventions for ->follow_link() are already fairly
complex.

What we have is
1) you can return -error; then you must release nameidata yourself
   and ->put_link() will _not_ be called.
2) you can do nd_set_link(nd, ERR_PTR(-error)) and return 0
3) you can do nd_set_link(nd, path) and return 0
4) you can return 0 (after having moved nameidata yourself)

jffs2 follow_link() is broken - it has an exit where it returns
-EIO and leaks nameidata.

[TG3]: Fix SerDes detection

A problem was reported by Grant Grundler on an HP rx8620 using IOX
Core LAN partno(A7109-6) 5701 copper NIC. The tg3 driver mistakenly
detects this NIC as having a SerDes PHY and link does not come up as a
result.

The problem was caused by an incorrectly programmed eeprom that set the
NIC_SRAM_DATA_CFG_PHY_TYPE_FIBER bit in the NIC_SRAM_DATA_CFG location.

This patch will override the NIC_SRAM_DATA_CFG_PHY_TYPE_FIBER bit if a
valid PHY ID is read from the MII registers on older 570x chips where
the MII interface is not used on SerDes chips. On newer chips such as
the 5780 that use MII for both copper and SerDes, SerDes detection must
rely on the eeprom.

This patch will make the SerDes detection identical to versions 3.25 and
older.

BCM5785 (HT1000) is a Opteron Southbridge from Serverworks/Broadcom that

identical to the Serverworks CSB6 IDE controller.  This patch adds support
for the new PCI device ID and also the support for this controller.

and then create an array with the same md device, the md drive will assume it
should have a bitmap too.  As the array can be created with a different md

Chuck Lever [Thu, 18 Aug 2005 18:24:12 +0000]
[PATCH] NFS: Introduce the use of inode->i_lock to protect fields in nfsi

Down the road we want to eliminate the use of the global kernel lock entirely
from the NFS client.  To do this, we need to protect the fields in the
nfs_inode structure adequately.  Start by serializing updates to the
"cache_validity" field.

Note this change addresses an SMP hang found by njw@osdl.org, where processes
deadlock because nfs_end_data_update and nfs_revalidate_mapping update the
"cache_validity" field without proper serialization.

Test plan:
 Millions of fsx ops on SMP clients.  Run Nick Wilson's breaknfs program on
 large SMP clients.

14 years ago[PATCH] NFS: use atomic bitops to manipulate flags in nfsi->flags
Chuck Lever [Thu, 18 Aug 2005 18:24:11 +0000]
[PATCH] NFS: use atomic bitops to manipulate flags in nfsi->flags

Introduce atomic bitops to manipulate the bits in the nfs_inode structure's
"flags" field.

Using bitops means we can use a generic wait_on_bit call instead of an ad hoc
locking scheme in fs/nfs/inode.c, so we can remove the "nfs_i_wait" field from
nfs_inode at the same time.

The other new flags field will continue to use bitmask and logic AND and OR.
This permits several flags to be set at the same time efficiently.  The
following patch adds a spin lock to protect these flags, and this spin lock
will later cover other fields in the nfs_inode structure, amortizing the cost
of using this type of serialization.

Test plan:
 Millions of fsx ops on SMP clients.
