This way we can remove TCP and DCCP specific versions of
sk->sk_prot->get_port: both v4 and v6 use inet_csk_get_port
sk->sk_prot->hash: inet_hash is directly used, only v6 need
a specific version to deal with mapped sockets
sk->sk_prot->unhash: both v4 and v6 use inet_hash directly
struct inet_connection_sock_af_ops also gets a new member, bind_conflict, so
that inet_csk_get_port can find the per family routine.
Now only the lookup routines receive as a parameter a struct inet_hashtable.
With this we further reuse code, reducing the difference among INET transport
protocols.
Eventually work has to be done on UDP and SCTP to make them share this
infrastructure and get as a bonus inet_diag interfaces so that iproute can be
used with these protocols.

The bf537 Ethernet MAC driver in the 2007R1.1-RC3 kernel (and the
current kernel) do not implement multicast hash filtering. This
is a performance problem if you have lots of multicast on your network.
This patch plugs the right bits into the multicast hash registers.

PHY read/write functions can potentially sleep (e.g., a PHY accessed
via I2C). The following changes were made to account for this:
* Change spin locks to mutex locks
* Add a BUG_ON() to phy_read() phy_write() to warn against
calling them from an interrupt context.
* Use work queue for PHY state machine handling since
it can potentially sleep
* Change phydev lock from spinlock to mutex

The driver should inform the stack when checksum has been performed by
the HW when both IP and TCP (or UDP) checksum flags are indicated by HW.
Previously, it would also inform the stack when only IP checksum flag
was indicated by HW. This can cause data corruption when IP fragments
are used. The IP Identification field can wrap around and cause data
from new fragments to fill into older fragment slots with same IP Id.
The stack would then not perform TCP/UDP checksum (after re-assembly of
all fragments) since driver falsely stated it was already calculated.

was added. This function can call back into t3_prep_adapter() at any

all the functions that it calls, which fixes

The ARP monitor functions currently acquire RTNL when performing
failover operations, but do so incorrectly (out of order). This causes
various warnings from might_sleep.
The ARP monitor isn't supported for any of the bonding modes
that actually require RTNL, so it is safe to not hold RTNL when
failing over in the ARP monitor.

I've seen reports of invalid stats in /proc/net/dev for bonding
interfaces, and found it's a pretty easy problem to reproduce. Since
the current code zeros the bonding stats when a read is requested and a
pointer to that data is returned to the caller we cannot guarantee that
the caller has completely accessed the data before a successive call to
request the stats zeroes the stats again.
This patch creates a new stack variable to keep track of the updated
stats and copies the data from that variable into the bonding stats
structure. This ensures that the value for any of the bonding stats
should not incorrectly return zero for any of the bonding statistics.
This does use more stack space and require an extra memcpy, but it seems
like a fair trade-off for consistently correct bonding statistics.

This patch eliminates a problem (reported by lockdep) in the
bond_set_multicast_list function. It first reduces the locking on
bond->lock to a simple read_lock, and second, adds netif_tx locking
around the bonding mc_list manipulations that occur outside of the
set_multicast_list function.
The original problem was related to IPv6 addrconf activity.

From: Thiemo Seufer <ths@networkno.de>
Date: Sat, 17 Nov 2007 22:29:13 +0000

Cc: linux-mips@linux-mips.org, ralf@linux-mips.org
Subject: [PATCH, REPOST] Fix/Rewrite of the mipsnet driver
Content-Type: text/plain; charset=us-ascii
Hello All,
currently the mipsnet driver fails after transmitting a number of
packages because SKBs are allocated but never freed. I fixed that
and coudn't refrain from removing the most egregious warts.
- mipsnet.h folded into mipsnet.c, as it doesn't provide any
useful external interface.
- Free SKB after transmission.
- Call free_irq in mipsnet_close, to balance the request_irq in
mipsnet_open.
- Removed duplicate read of rxDataCount.
- Some identifiers are now less verbose.
- Removed dead and/or unnecessarily complex code.
- Code formatting fixes.
Tested on Qemu's mipssim emulation, with this patch it can boot a
Debian NFSroot.

Resubmitting patch from Al Viro <viro@zeniv.linux.org.uk>, with subject -
[PATCH] s2io LRO bugs.
a) initiate_new_session() sets ->tcp_ack to ntohl(...); everything
else stores and expects to find there the net-endian value.
b) check for monotonic timestamps in verify_l3_l4_lro_capable()
compares the value sitting in TCP option (right there in the skb->data,
net-endian 32bit) with the value picked from earlier packet.
Doing that without ntohl() is an interesting idea and it might even
work occasionally; unfortunately, it's quite broken.
