[Bluetooth] Add locking for bt_proto array manipulation

2006-10-16T06:14:34+00:00

The bt_proto array needs to be protected by some kind of locking to
prevent a race condition between bt_sock_create and bt_sock_register.

And in addition all calls to sk_alloc need to be made GFP_ATOMIC now.

[Bluetooth] Handle return values from driver core functions

2006-10-16T06:14:28+00:00

Some return values of the driver core register and create functions
are not handled and so might cause unexpected problems.

[Bluetooth] Use real devices for host controllers

2006-07-04T02:54:02+00:00

This patch converts the Bluetooth class devices into real devices. The
Bluetooth class is kept and the driver core provides the appropriate
symlinks for backward compatibility.

[BLUETOOTH] sco: Possible double free.

2006-04-10T05:25:29+00:00

this fixes coverity bug id #1068.
hci_send_sco() frees skb if (skb->len > hdev->sco_mtu).
Since it returns a negative error value only in this case, we
can directly return here.

[NET]: move struct proto_ops to const

2006-01-03T21:11:15+00:00

I noticed that some of 'struct proto_ops' used in the kernel may share
a cache line used by locks or other heavily modified data. (default
linker alignement is 32 bytes, and L1_CACHE_LINE is 64 or 128 at
least)

This patch makes sure a 'struct proto_ops' can be declared as const,
so that all cpus can share all parts of it without false sharing.

This is not mandatory : a driver can still use a read/write structure
if it needs to (and eventually a __read_mostly)

I made a global stubstitute to change all existing occurences to make
them const.

This should reduce the possibility of false sharing on SMP, and
speedup some socket system calls.

[NET]: Avoid atomic xchg() for non-error case

2006-01-03T21:10:44+00:00

It also looks like there were 2 places where the test on sk_err was
missing from the event wait logic (in sk_stream_wait_connect and
sk_stream_wait_memory), while the rest of the sock_error() users look
to be doing the right thing.  This version of the patch fixes those,
and cleans up a few places that were testing ->sk_err directly.

[Bluetooth]: Remove the usage of /proc completely

2005-11-08T17:57:38+00:00

This patch removes all relics of the /proc usage from the Bluetooth
subsystem core and its upper layers. All the previous information are
now available via /sys/class/bluetooth through appropriate functions.

[PATCH] gfp flags annotations - part 1

2005-10-08T22:00:57+00:00

 - added typedef unsigned int __nocast gfp_t;

 - replaced __nocast uses for gfp flags with gfp_t - it gives exactly
   the same warnings as far as sparse is concerned, doesn't change
   generated code (from gcc point of view we replaced unsigned int with
   typedef) and documents what's going on far better.
