Hi,
I would like to propose following patches for net-next-2.6/3.1 [1]. It
is not really based on your net-next-2.6 tree, but directly on v3.0-rc1.
I hope that this is ok - thought that you will merge that version
anyway. Just wanted to get these patches out before doing the really
work (reducing the amount of patches you get in a single pull request).
Most patches are only cleanup patches - nothing really interesting.
Antonio also moved the protocol specific seq_before/seq_after function
to main.h like you told us [2]. Now he can use it in his translation
table query patches (they are still moving, so he needs to hunt them
down before I can submit them).
thanks,
Sven
[1] wow, that sounds creepy
[2] https://lkml.org/lkml/2011/5/19/88
The following changes since commit 55922c9d1b84b89cb946c777fddccb3247e7df2c:
Linux 3.0-rc1 (2011-05-29 17:43:36 -0700)
are available in the git repository at:
git://git.open-mesh.org/ecsv/linux-merge.git batman-adv/next
Antonio Quartulli (4):
batman-adv: move neigh_node->if_incoming->if_status check in find_router()
batman-adv: move smallest_signed_int(), seq_before() and seq_after() into main.h
batman-adv: use is_broadcast_ether_addr() instead of compare_eth(.., brd_addr)
batman-adv: a multiline comment should precede the variable it is describing
Sven Eckelmann (13):
batman-adv: Use kzalloc rather than kmalloc followed by memset with 0
batman-adv: Annotate functions with format strings
batman-adv: Print jiffies as unsigned long
batman-adv: Remove comparising < 0 for unsigned type
batman-adv: Don't do pointer arithmetic with void*
batman-adv: Add const type qualifier for pointers
batman-adv: Only use int up and down gw representation
batman-adv: Remove explicit casts cast from void* for store
batman-adv: Remove casts from type x to type x
batman-adv: Calculate sizeof using variable insead of types
batman-adv: Use rcu_dereference_protected by update-side
batman-adv: Check type of x and y in seq_(before|after)
batman-adv: Ensure that we really have route changes in update_route

From: Antonio Quartulli <ordex@autistici.org>
Every time that find_router() is invoked, if_status has to be compared with
IF_ACTIVE. Moving this comparison inside find_router() will avoid to write it
each time.

The size of void is currently set by gcc to 1, but is not well defined
in general. Therefore it is more advisable to cast it to char* before
doing pointer arithmetic.

batman-adv uses pointers which are marked as const and should not
violate that type qualifier by passing it to functions which force a
cast to the non-const version.

From: Sven Eckelmann @ 2011-05-30 7:22 UTC (permalink / raw)
To: davem; +Cc: netdev, b.a.t.m.a.n
It is not save to provide memory for an int and then cast the pointer to
it to long*. It is better to standardize the up and down gateway
bandwith representation to simple ints and only use long inside
conversation routines.

It is not necessary to cast a void* to the pointer type when we just
store it and don't want to do pointer arithmetic before the actual
assignment.

Casting from pointer like 'struct orig_node*' to 'struct orig_node *'
doesn't provide any additional functionality and can be savely removed.

Documentation/CodingStyle recommends to use the form
p = kmalloc(sizeof(*p), ...);
to calculate the size of a struct and not the version where the struct
name is spelled out to prevent bugs when the type of p changes. This
also seems appropriate for manipulation of buffers when they are
directly associated with p.

Usually rcu_dereference isn't necessary in situations were the
RCU-protected data structure cannot change, but sparse and lockdep still
need a similar functionality for analysis. rcu_dereference_protected
implements the reduced version which should be used to support the
dynamic and static analysis.

smallest_signed_int(), seq_before() and seq_after() are very useful
functions that help to handle comparisons between sequence numbers.
However they were only defined in vis.c. With this patch every
batman-adv function will be able to use them.

seq_before and seq_after depend on the fact that both sequence numbers
have the same type and thus the same bitwidth. We can ensure that by
compile time checking using a compare between the pointer to the
temporary buffers which were created using the typeof of both
parameters. For example gcc would create a warning like
"warning: comparison of distinct pointer types lacks a cast".

The debug output of update_route has tests for "route deleted" and "route
added". All other situations are handled as "route changed". This is not
true because neigh_node and curr_router could be both NULL.
The function is not called in this situation, but the code might be
interpreted wrong when reading it without this test.
