8 years agodrivers/net: Remove IRQF_SAMPLE_RANDOM flag from network drivers
Javier Martinez Canillas [Mon, 28 Mar 2011 16:27:31 +0000]
drivers/net: Remove IRQF_SAMPLE_RANDOM flag from network drivers

The IRQF_SAMPLE_RANDOM flag is marked as deprecated and will be removed.

Every input point to the kernel's entropy pool have to better document the
type of entropy source it is.

drivers/char/random.c now implements a set of interfaces that can be used for
devices to collect enviromental noise. IRQF_SAMPLE_RANDOM will be replaced
with these add_*_randomness exported functions.

Network drivers are not a good source of entropy. They use as a source of
entropy essentially a remote host. Which means that the source of entropy can
be potentially controlled by an attacker. Also, with heavy workloads the
entropy decreases due to less hardware interrupts happening thanks to irq
mitigation and NAPI.

If a system relies in its network interface as a entropy source it has a false
sense of security. Systems that don't have devices whose drivers are good
sources of entropy, should either use a hardware random number generator or
feed the kernel's entropy pool from userspace using other sources of entropy
such as EGD, video_entropyd, timer_entropyd and audio-entropyd.

8 years agoenic: Add support for PORT_REQUEST_PREASSOCIATE_RR
Roopa Prabhu [Tue, 29 Mar 2011 20:36:07 +0000]
enic: Add support for PORT_REQUEST_PREASSOCIATE_RR

Current enic code only supports ASSOCIATE and DISASSOCIATE port profile
operations. This patch adds enic support for port profile
PORT_REQUEST_PREASSOCIATE_RR operation. The VIC adapter (8021qbh) is capable
of handling port profile requests done in two steps namely PREASSOCIATE_RR
and ASSOCIATE today. The motivation to support PREASSOCIATE_RR comes mainly
from its use as an optimization during VM migration ie, to do resource
reservation on destination host before resources on source host are released.

PREASSOCIATE_RR is a VDP operation and according to the latest at IEEE,
8021qbh will also need to support VDP commands.

In addition to handling the new PORT_REQUEST_PREASSOCIATE_RR operation
this patch also does the below:
- Introduces handlers for PORT_REQUEST operations
- Moves most of the port profile handling code to new files enic_pp.[ch]
- Uses new fw devcmds for port profile operations

 - commit eead4d5c63ff ("powerpc: qe_ic: Rename get_irq_desc_data and
   get_irq_desc_chip") made the helper functions use
   irq_desc_get_handler_data() instead of the legacy (and no longer
   existing) get_irq_desc_data.

 - commit d4db35e8dc96 ("powerpc/qe_ic: Fix another breakage from the
   irq_data conversion") used irq_desc_get_chip_data() instead.

According to Thomas, the former is the correct direct conversion, but it
does look like both should work (arch/powerpc/sysdev/qe_lib/qe_ic.c
seems to initialize both to the same thing), and the chip data in some
ways is the more logical.  Somebody should really decide on one of the
other.

This merge picks irq_desc_get_handler_data() as the straightforward pure
conversion to new names, as per Thomas.

net/usb: Ethernet quirks for the LG-VL600 4G modem

This adds a driver for the CDC Ethernet part of this modem.  The
device's ID is blacklisted in cdc_ether.c and is white-listed in
this new driver because of the quirks needed to make it useful.
The modem's firmware exposes a CDC ACM port for modem control and a
CDC Ethernet port for network data.  The descriptors look fine but
both ports actually are some sort of multiplexers requiring non-
standard headers added/removed from every packet or they get
ignored.  All information is based on a usb traffic log from a
Windows machine.

On the Verizon 4G network I've seen speeds up to 1.1MB/s so far with
this driver, a speed-o-meter site reports 16.2Mbps/10.5Mbps.

Linus Lüssing [Sat, 26 Mar 2011 20:27:24 +0000]
bridge: mcast snooping, fix length check of snooped MLDv1/2

"len = ntohs(ip6h->payload_len)" does not include the length of the ipv6
header itself, which the rest of this function assumes, though.

This leads to a length check less restrictive as it should be in the
following line for one thing. For another, it very likely leads to an
integer underrun when substracting the offset and therefore to a very
high new value of 'len' due to its unsignedness. This will ultimately
lead to the pskb_trim_rcsum() practically never being called, even in
the cases where it should.

net: gre: provide multicast mappings for ipv4 and ipv6

My commit 6d55cb91a0020ac0 (gre: fix hard header destination
address checking) broke multicast.

The reason is that ip_gre used to get ipgre_header() calls with
zero destination if we have NOARP or multicast destination. Instead
the actual target was decided at ipgre_tunnel_xmit() time based on
per-protocol dissection.

Instead of allowing the "abuse" of ->header() calls with invalid
destination, this creates multicast mappings for ip_gre. This also
fixes "ip neigh show nud noarp" to display the proper multicast
mappings used by the gre device.

powerpc: Fix accounting of softirq time when idle

commit cf9efce0ce31 (powerpc: Account time using timebase rather
than PURR) used in_irq() to detect if the time was spent in
interrupt processing. This only catches hardirq context so if we
are in softirq context and in the idle loop we end up accounting it
as idle time. If we instead use in_interrupt() we catch both softirq
and hardirq time.

The issue was found when running a network intensive workload. top
showed the following:

0.0%us,  1.1%sy,  0.0%ni, 85.7%id,  0.0%wa,  9.9%hi,  3.3%si,  0.0%st

85.7% idle. But this was wildly different to the perf events data.
To confirm the suspicion I ran something to keep the core busy:

# yes > /dev/null &

8.2%us,  0.0%sy,  0.0%ni,  0.0%id,  0.0%wa, 10.3%hi, 81.4%si,  0.0%st

We only got 8.2% of the CPU for the userspace task and softirq has
shot up to 81.4%.

With the patch below top shows the correct stats:

0.0%us,  0.0%sy,  0.0%ni,  5.3%id,  0.0%wa, 13.3%hi, 81.3%si,  0.0%st

powerpc/xics: Fix numberspace mismatch from irq_desc conversion

commit 79f26c268ebad29bd75d078cfc09d3d82b30ccbd (powerpc:
platforms/pseries irq_data conversion) pushed irq_desc down into many
functions, dererencing the descriptor irq field as late as possible.

But it incorrectly passed a linix virtural irq number to RTAS,
resulting in the interrupt not being disabled and possibly
other bad things, such as another interrupt being disabled and/or
a checkstop.

In addition this missed the point of xics_mask_unknown_vec and
the seperation of xics_mask_real_irq from xics_mask_irq.  When
xics_mask_unknown_vec is called it's because the hardware delivered an
irq source for which we have no linux irq allocated, and thefore we can
not have an irq_desc allocated.

Revert xics_mask_real_irq to its prior version, naming the argument
hwirq to highlight the difference.

powerpc: Restore some misc devices to our configs

Uwe Kleine-König reported:

while working on an defconfig (arm/mx27) I noticed that just updating
it[1] results in removing CONFIG_EEPROM_AT24=y.  The reason is that
since commit

v2.6.36-5965-g5f2365d (misc devices: do not enable by default)

MISC_DEVICES isn't enabled anymore by default.  So all defconfigs that
have CONFIG_SOME_SYMBOL=y (or =m) (with SOME_SYMBOL depending on
MISC_DEVICES) but not CONFIG_MISC_DEVICES=y suffer from the same
problem.

This restores those misc devices to the powerpc defconfigs.
