Its easy to eat all kernel memory and trigger NMI watchdog, using an
exploit program that queues unix sockets on top of others.
lkml ref : http://lkml.org/lkml/2010/11/25/8
This mechanism is used in applications, one choice we have is to have a
recursion limit.
Other limits might be needed as well (if we queue other types of files),
since the passfd mechanism is currently limited by socket receive queue
sizes only.
Add a recursion_level to unix socket, allowing up to 4 levels.
Each time we send an unix socket through sendfd mechanism, we copy its
recursion level (plus one) to receiver. This recursion level is cleared
when socket receive queue is emptied.

In commit 58933c64(ucc_geth: Fix the wrong the Rx/Tx FIFO size),
the UCC_GETH_UTFTT_INIT is set to 512 based on the recommendation
of the QE Reference Manual. But that will sometimes cause tx halt
while working in half duplex mode.
According to errata draft QE_GENERAL-A003(High Tx Virtual FIFO
threshold size can cause UCC to halt), setting UTFTT less than
[(UTFS x (M - 8)/M) - 128] will prevent this from happening
(M is the minimum buffer size).
The patch changes UTFTT back to 256.

inet sockets corresponding to passive connections are added to the bind hash
using ___inet_inherit_port(). These sockets are later removed from the bind
hash using __inet_put_port(). These two functions are not exactly symmetrical.
__inet_put_port() decrements hashinfo->bsockets and tb->num_owners, whereas
___inet_inherit_port() does not increment them. This results in both of these
going to -ve values.
This patch fixes this by calling inet_bind_hash() from ___inet_inherit_port(),
which does the right thing.
'bsockets' and 'num_owners' were introduced by commit a9d8f9110d7e953c
(inet: Allowing more than 64k connections and heavily optimize bind(0))

We register lapb when tty is created, but unregister it only when the
device is UP. So move the lapb_unregister to x25_asy_close_tty after
the device is down.
The old behaviour causes ldisc switching to fail each second attempt,
because we noted for us that the device is unused, so we use it the
second time, but labp layer still have it registered, so it fails
obviously.

tcp_win_from_space() does the following:
if (sysctl_tcp_adv_win_scale <= 0)
return space >> (-sysctl_tcp_adv_win_scale);
else
return space - (space >> sysctl_tcp_adv_win_scale);
"space" is int.
As per C99 6.5.7 (3) shifting int for 32 or more bits is
undefined behaviour.
Indeed, if sysctl_tcp_adv_win_scale is exactly 32,
space >> 32 equals space and function returns 0.
Which means we busyloop in tcp_fixup_rcvbuf().
Restrict net.ipv4.tcp_adv_win_scale to [-31, 31].

Vegard Nossum found a unix socket OOM was possible, posting an exploit
program.
My analysis is we can eat all LOWMEM memory before unix_gc() being
called from unix_release_sock(). Moreover, the thread blocked in
unix_gc() can consume huge amount of time to perform cleanup because of
huge working set.
One way to handle this is to have a sensible limit on unix_tot_inflight,
tested from wait_for_unix_gc() and to force a call to unix_gc() if this
limit is hit.
This solves the OOM and also reduce overall latencies, and should not
slowdown normal workloads.

Some aspects of PHY initialization are board dependent, things like
indicator LED connections and some clocking modes cannot be determined
by probing. The dev_flags element of struct phy_device can be used to
control these things if an appropriate value can be passed from the
Ethernet driver. We run into problems however if the PHY connections
are specified by the device tree. There is no way for the Ethernet
driver to know what flags it should pass.
If we are using the device tree, the struct phy_device will be
populated with the device tree node corresponding to the PHY, and we
can extract extra configuration information from there.
The next question is what should the format of that information be?
It is highly device specific, and the device tree representation
should not be tied to any arbitrary kernel defined constants. A
straight forward representation is just to specify the exact bits that
should be set using the "marvell,reg-init" property:
phy5: ethernet-phy@5 {
reg = <5>;
compatible = "marvell,88e1149r";
marvell,reg-init =
/* led[0]:1000, led[1]:100, led[2]:10, led[3]:tx */
<3 0x10 0 0x5777>, /* Reg 3,16 <- 0x5777 */
/* mix %:0, led[0123]:drive low off hiZ */
<3 0x11 0 0x00aa>, /* Reg 3,17 <- 0x00aa */
/* default blink periods. */
<3 0x12 0 0x4105>, /* Reg 3,18 <- 0x4105 */
/* led[4]:rx, led[5]:dplx, led[45]:drive low off hiZ */
<3 0x13 0 0x0a60>; /* Reg 3,19 <- 0x0a60 */
};
phy6: ethernet-phy@6 {
reg = <6>;
compatible = "marvell,88e1118";
marvell,reg-init =
/* Fix rx and tx clock transition timing */
<2 0x15 0xffcf 0>, /* Reg 2,21 Clear bits 4, 5 */
/* Adjust LED drive. */
<3 0x11 0 0x442a>, /* Reg 3,17 <- 0442a */
/* irq, blink-activity, blink-link */
<3 0x10 0 0x0242>; /* Reg 3,16 <- 0x0242 */
};
The Marvell PHYs have a page select register at register 22 (0x16), we
can specify any register by its page and register number. These are
the first and second word. The third word contains a mask to be ANDed
with the existing register value, and the fourth word is ORed with the
result to yield the new register value. The new marvell_of_reg_init
function leaves the page select register unchanged, so a call to it
can be dropped into the .config_init functions without unduly
affecting the state of the PHY.
If CONFIG_OF_MDIO is not set, there is no of_node, or no
"marvell,reg-init" property, the PHY initialization is unchanged.

Driver appears to be mistaking the permission field with default value
in the case of debug and qlge_irq_type.
Driver is also passing debug as a bitmask into netif_msg_init()
which wants a number of bits. Ron Mercer suggests we should
change this to pass in -1 so the defaults get used instead,
which makes the default much less verbose.

VMWare reports that the e1000 driver has a bug when bringing down the
interface, such that interrupts are not disabled in the hardware but the
driver stops reporting that it consumed the interrupt.
The fix is to set the driver's "down" flag later in the routine,
after all the timers and such have exited, preventing the interrupt
handler from being called and exiting early without handling the
interrupt.

ipg.c:
The id [SUNDANCE, 0x1021] (=[0x13f0, 0x1021]) is defined
at dl2k.h and ipg.c.
But this device works better with dl2k driver.
This problem is similar with the commit
[25cca5352712561fba97bd37c495593d641c1d39
ipg: Remove device claimed by dl2k from pci id table]
