gianfar: Fix Wake-on-LAN support
commit
0f0ca340e57bd7446855fefd07a64249acf81223 ("phy: power

Now phylib turns off PHY power during suspend, and thus WOL
doesn't work anymore.
This patch workarounds the issue by enabling wakeup in the MDIO
device, i.e. just restores the old behaviour for the gianfar
driver. Note that this way all PHYs on a given MDIO bus won't
be turned off during suspend, which isn't good from the power
saving point of view.
A proper, per netdevice wakeup management support will need
a bit reworked phylib suspend/resume logic.

The definitions needed for the wimax stack and i2400m driver debug

(by them being placed in the debugfs.c files); thus the build broke in
2.6.29-rc3 when debugging was enabled (CONFIG_WIMAX_DEBUG) and
DEBUG_FS was disabled.
These definitions are always needed if debug is enabled at compile

Actually I did some testing and added a few printks and found that the
st->cur_skb->data was 0 and hence the ptr used by iscsi_tcp was null.
This caused the kernel panic.
if (abs_offset < block_limit) {
- *data = st->cur_skb->data + abs_offset;
+ *data = st->cur_skb->data + (abs_offset - st->stepped_offset);
I enabled the debug_tcp and with a few printks found that the code did
not go to the next_skb label and could find that the sequence being
followed was this -
It hit this if condition -
if (st->cur_skb->next) {
st->cur_skb = st->cur_skb->next;
st->frag_idx = 0;
goto next_skb;
And so, now the st pointer is shifted to the next skb whereas actually
it should have hit the second else if first since the data is in the
frag_list.

- Don't try to forward link-local multicast packets.
- Don't reset skb2->dev before calling ip6_mr_input() so packets can
be identified as coming from the PIM register vif properly.
net/ipv6/ip6mr.c:
- Fix incoming PIM register messages processing:
* The IPv6 pseudo-header should be included when checksumming PIM
messages (RFC 4601 section 4.9; RFC 3973 section 4.7.1).
* Packets decapsulated from PIM register messages should have
skb->protocol ETH_P_IPV6.
- Enable/disable IPv6 multicast forwarding on the corresponding
interface when a routing daemon adds/removes a multicast virtual
interface.
- Remove incorrect skb_pull() to fix userspace signaling.
- Enable/disable global IPv6 multicast forwarding when an IPv6
multicast routing socket is opened/closed.
net/ipv6/route.c:
- Don't use strict routing logic for packets decapsulated from PIM
register messages (similar to disabling rp_filter for the IPv4
case).

net: wrong test in inet_ehash_locks_alloc()
In commit
9db66bdcc83749affe61c61eb8ff3cf08f42afec (net: convert
TCP/DCCP ehash rwlocks to spinlocks), I forgot to change one
occurrence of rwlock_t to spinlock_t
I believe sizeof(raw_spinlock_t) might be > 0 on !CONFIG_SMP if
CONFIG_DEBUG_SPINLOCK while sizeof(raw_rwlock_t) should be 0 in this
case.
Fortunatly, CONFIG_DEBUG_SPINLOCK adds fields to both spinlock_t and
rwlock_t, but at this might change in the future (being able to debug
spinlocks but not rwlocks for example), better to be safe.

tcp: Fix length tcp_splice_data_recv passes to skb_splice_bits.
tcp_splice_data_recv has two lengths to consider: the len parameter it
gets from tcp_read_sock, which specifies the amount of data in the skb,
and rd_desc->count, which is the amount of data the splice caller still
wants. Currently it passes just the latter to skb_splice_bits, which then
splices min(rd_desc->count, skb->len - offset) bytes.
Most of the time this is fine, except when the skb contains urgent data.
In that case len goes only up to the urgent byte and is less than
skb->len - offset. By ignoring len tcp_splice_data_recv may a) splice
data tcp_read_sock told it not to, b) return to tcp_read_sock a value > len.
Now, tcp_read_sock doesn't handle used > len and leaves the socket in a
bad state (both sk_receive_queue and copied_seq are bad at that point)
resulting in duplicated data and corruption.
Fix by passing min(rd_desc->count, len) to skb_splice_bits.

udp: optimize bind(0) if many ports are in use
commit
9088c5609584684149f3fb5b065aa7f18dcb03ff
(udp: Improve port randomization) introduced a regression for UDP bind() syscall
to null port (getting a random port) in case lot of ports are already in use.
This is because we do about 28000 scans of very long chains (220 sockets per chain),
with many spin_lock_bh()/spin_unlock_bh() calls.
Fix this using a bitmap (64 bytes for current value of UDP_HTABLE_SIZE)
so that we scan chains at most once.
Instead of 250 ms per bind() call, we get after patch a time of 2.9 ms

gfar_vlan_rx_register() checks for "if (old_grp == grp)" and tries

According to net/8021q/vlan.c VLAN core issues rx_register() callback:
1. In register_vlan_dev() only on a newly created group;
2. In unregister_vlan_dev() only if the group becomes empty.

inotify: clean up inotify_read and fix locking problems
If userspace supplies an invalid pointer to a read() of an inotify
instance, the inotify device's event list mutex is unlocked twice.
This causes an unbalance which effectively leaves the data structure
unprotected, and we can trigger oopses by accessing the inotify
instance from different tasks concurrently.
The best fix (contributed largely by Linus) is a total rewrite
of the function in question:

This is not a big issue because fuse_notify_poll_wakeup() should be

fuse: destroy bdi on umount
If a fuse filesystem is unmounted but the device file descriptor
remains open and a new mount reuses the old device number, then the

WARNING: at fs/sysfs/dir.c:462 sysfs_add_one+0x35/0x3d()
