iwlwifi: Fix mode changes (ad-hoc <--> managed)

This fix allows to move between modes (ad-hoc to managed, and vice versa).
Since mode changes can only be done while driver is down, check for ibss
support can only be made when the channel is set (afte the driver goes up).

11 years agoiwlwifi enabling IBSS (Ad-Hoc) mode
Assaf Krauss [Thu, 12 Jun 2008 01:47:05 +0000]
iwlwifi enabling IBSS (Ad-Hoc) mode

This patch enables ibss mode. It consists of two changes upon entering ibss
mode:
1. Removing the redundant line which clears the driver's station table.
   This line creates a discrepancy between the driver and the FW's station
   table. This prevented the generation of beacons.
2. Assigning a default value to priv's assoc_id. Normally given by an AP in
   STA mode, this field is used as an indication for association. Being 0,
   it prevented normal TX flow.
3. Remove a redundant ADD_STA command that cause uCode error.
4. Delay the set_mode until after the uCode is ready.

rt2x00: Don't kick TX queue after each frame

TX queues shouldn't be kicked after each frame that is put into the
queue.  This could cause problems during RTS and CTS-to-self as well
as with fragmentation. In all those cases you want all frames to be
send out in a single burst. Off course we shouldn't let the queue fill
up entirely, thus we introduce a 10% threshold which, when reached,
will force the frames to be send out regardless of the frame.

In addition we should prevent queues to become full in such a way
that the tx() handler can fail. Instead of stopping the queue when
it is full, we should stop it when it is below the threshold.

rt2x00: Make rt2x00_set/get_field macros

The rt2x00_set_field functions are very often used,
but GCC is better able to optimize them when they
are macros instead of static inline functions.

After changing it to macro's each rt2x00 driver will
loose about ~3500 bytes in size.

11 years agort2x00: Calculate register offset during compile time
Ivo van Doorn [Tue, 3 Jun 2008 20:45:35 +0000]
rt2x00: Calculate register offset during compile time

By using __ffs() the register offsets were always calculated
at run-time which all FIELD32/FIELD16 definitions were builtin
constants. This means we can heavily optimize the register handling
by allowing GCC to do all the work during compilation.

Add some compile_ffs() macros to perform the calculation at
compile time. After this each rt2x00 module size is reduced
by ~2500 bytes. And the stack size of several functions is reduced
as well which further limits the number of rt2x00 results in
'make checkstack'.

v2: Merge GertJan's bugfix of patch [1/11] directly into this patch
      instead of providing it as seperate patch.
v3: Add extra parentheses when bitshifting __x

[netdrvr] Fix 8390 build breakage

From: tony@bakeyournoodle.com (Tony Breeds)

The commit 3f8cb098859bbea29d7b3765a3102e4a6bf81b85
(drivers/net/lib8390: fix warning, trim trailing whitespace) removed
ei_local from ei_tx_err() and ei_rx_overrun() resulting in the following
build errors on m68k and sh:

Using /scratch1/tony/next as source for kernel
GEN     /scratch1/tony/next_out/Makefile
CHK     include/linux/version.h
CHK     include/linux/utsrelease.h
CALL    /scratch1/tony/next/scripts/checksyscalls.sh
CHK     include/linux/compile.h
CC [M] drivers/net/zorro8390.o
In file included from /scratch1/tony/next/drivers/net/zorro8390.c:47:
drivers/net/lib8390.c: In function 'ei_tx_err':
drivers/net/lib8390.c:556: error: 'ei_local' undeclared (first use in this function)
drivers/net/lib8390.c:556: error: (Each undeclared identifier is reported only once

make[2]: *** [drivers/net] Error 2

The problem is that ei_inb_p() is using various #defines (from
drivers/net/8390.h) that use EI_SHIFT, which in some drivers on some
architectures use ei_local.  Tag ei_local as "__maybe_unused" to keep it
around and keep the warnings the original commit is trying to silence
... silenced.

ipv6 netns: Address labels per namespace

This pacth makes IPv6 address labels per network namespace.
It keeps the global label tables, ip6addrlbl_table, but
adds a 'net' member to each ip6addrlbl_entry.
This new member is taken into account when matching labels.

Changelog
=========
* v1: Initial version
* v2:
  * Minize the penalty when network namespaces are not configured:
      *  the 'net' member is added only if CONFIG_NET_NS is
         defined. This saves space when network namespaces are not
         configured.
      * 'net' value is retrieved with the inlined function
         ip6addrlbl_net() that always return &init_net when
         CONFIG_NET_NS is not defined.
  * 'net' member in ip6addrlbl_entry renamed to the less generic
    'lbl_net' name (helps code search).

netfilter: nf_conntrack: properly account terminating packets

Currently the last packet of a connection isn't accounted when its causing
abnormal termination.

Introduces nf_ct_kill_acct() which increments the accounting counters on
conntrack kill. The new function was necessary, because there are calls
to nf_ct_kill() which don't need accounting:

nf_conntrack_proto_tcp.c line ~847:
Kills ct and returns NF_REPEAT. We don't want to count twice.

nf_conntrack_proto_tcp.c line ~880:
Kills ct and returns NF_DROP. I think we don't want to count dropped
packets.

nf_conntrack_netlink.c line ~824:
As far as I can see ctnetlink_del_conntrack() is used to destroy a
conntrack on behalf of the user. There is an sk_buff, but I don't think
this is an actual packet. Incrementing counters here is therefore not
desired.

netfilter: ip_tables: add iptables security table for mandatory access control rules

The following patch implements a new "security" table for iptables, so
that MAC (SELinux etc.) networking rules can be managed separately to
standard DAC rules.

This is to help with distro integration of the new secmark-based
network controls, per various previous discussions.

The need for a separate table arises from the fact that existing tools
and usage of iptables will likely clash with centralized MAC policy
management.

The SECMARK and CONNSECMARK targets will still be valid in the mangle
table to prevent breakage of existing users.
