Linus Torvalds c2eca00fec Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net 
Pull networking fixes from David Miller:

 1) Don't save TIPC header values before the header has been validated,
    from Jon Paul Maloy.

 2) Fix memory leak in RDS, from Zhu Yanjun.

 3) We miss to initialize the UID in the flow key in some paths, from
    Julian Anastasov.

 4) Fix latent TOS masking bug in the routing cache removal from years
    ago, also from Julian.

 5) We forget to set the sockaddr port in sctp_copy_local_addr_list(),
    fix from Xin Long.

 6) Missing module ref count drop in packet scheduler actions, from
    Roman Mashak.

 7) Fix RCU annotations in rht_bucket_nested, from Herbert Xu.

 8) Fix use after free which happens because L2TP's ipv4 support returns
    non-zero values from it's backlog_rcv function which ipv4 interprets
    as protocol values. Fix from Paul Hüber.

know that you need one of the others.
config CRC32_SLICEBY8
bool "Slice by 8 bytes"
help
Calculate checksum 8 bytes at a time with a clever slicing algorithm.
This is the fastest algorithm, but comes with a 8KiB lookup table.
Most modern processors have enough cache to hold this table without
thrashing the cache.
This is the default implementation choice. Choose this one unless
you have a good reason not to.
config CRC32_SLICEBY4
bool "Slice by 4 bytes"

This is a bit slower than slice by 8, but has a smaller 4KiB lookup
table.
Only choose this option if you know what you are doing.

config BCH_CONST_PARAMS

help
Drivers may select this option to force specific constant
values for parameters 'm' (Galois field order) and 't'
(error correction capability). Those specific values must
be set by declaring default values for symbols BCH_CONST_M
and BCH_CONST_T.
Doing so will enable extra compiler optimizations,
improving encoding and decoding performance up to 2x for
usual (m,t) values (typically such that m*t < 200).
When this option is selected, the BCH library supports
only a single (m,t) configuration. This is mainly useful
for NAND flash board drivers requiring known, fixed BCH
parameters.
config BCH_CONST_M
int
range 5 15
help
Constant value for Galois field order 'm'. If 'k' is the
number of data bits to protect, 'm' should be chosen such
that (k + m*t) <= 2**m - 1.
Drivers should declare a default value for this symbol if
they select option BCH_CONST_PARAMS.
config BCH_CONST_T

Constant value for error correction capability in bits 't'.
Drivers should declare a default value for this symbol if

# This actually supports modular compilation, but the module overhead

# no need bother prompting for a manual decision:
# prompt "glob_match() function"
help
This option provides a glob_match function for performing
simple text pattern matching. It originated in the ATA code
to blacklist particular drive models, but other device drivers
may need similar functionality.
All drivers in the Linux kernel tree that require this function
should automatically select this option. Say N unless you
are compiling an out-of tree driver which tells you that it
depends on this.
config GLOB_SELFTEST
tristate "glob self-test on init"
depends on GLOB
help
This option enables a simple self-test of the glob_match
function on startup. It is primarily useful for people
working on the code to ensure they haven't introduced any
regressions.
It only adds a little bit of code and slows kernel boot (or
module load) by a small amount, so you're welcome to play with
it, but you probably don't need it.
