2008-04-21hamradio: Remove unneeded and deprecated cli()/sti() calls in dmascc.cMark Asselstine
These cli()/sti() calls are made in start_timer() and are therefor redundant since the register_lock is now used to protect register io from within scc_isr() and write_scc() (where all calls to start_timer() originate).

2008-04-21[NETNS]: Remove empty ->init callback.Pavel Emelyanov
The netns start-stop engine can happily live with any of init or exit callbacks set to NULL. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-04-21[DCCP]: Convert do_gettimeofday() to getnstimeofday().YOSHIFUJI Hideaki
What do_gettimeofday() does is to call getnstimeofday() and to convert the result from timespec{} to timeval{}. We do not always need timeval{} and we can convert timespec{} when we really need (to print).

2008-04-21[NETNS]: Don't initialize err variable twice.Pavel Emelyanov

2008-04-21[NETNS]: The ip6_fib_timer can work with garbage on net namespace stop.Pavel Emelyanov
The del_timer() function doesn't guarantee, that the timer callback is not active by the time it exits. Thus, the fib6_net_exit() may kfree() all the data, that is required by the fib6_run_gc(). The race window is tiny, but slab poisoning can trigger this bug. Using del_timer_sync() will cure this. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-04-21[IPV4]: Convert do_gettimeofday() to getnstimeofday().YOSHIFUJI Hideaki
What do_gettimeofday() does is to call getnstimeofday() and to convert the result from timespec{} to timeval{}. After that, these callers convert the result again to msec. Use getnstimeofday() and convert the units at once. Signed-off-by: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2008-04-20[NET]: Expose netdevice dev_id through sysfsDavid Woodhouse
Expose dev_id to userspace, because it helps to disambiguate between interfaces where the MAC address is unique. This should allow us to simplify the handling of persistent naming for S390 network devices in udev -- because it can depend on a simple attribute of the device like the other match criteria, rather than having a special case for SUBSYSTEMS=="ccwgroup".

2008-04-19tg3: 5701 DMA corruption fixMatt Carlson
Herbert Xu's commit fb93134dfc2a6e6fbedc7c270a31da03fce88db9, entitled "[TCP]: Fix size calculation in sk_stream_alloc_pskb", has triggered a bug in the 5701 where the 5701 DMA engine will corrupt outgoing packets. This problem only happens when the starting address of the packet matches a certain range of offsets and only when the 5701 is placed downstream of a particular Intel bridge. This patch detects the problematic bridge and if present, readjusts the starting address of the packet data to a dword aligned boundary.

2008-04-19Security: Introduce security= boot parameterAhmed S. Darwish
Add the security= boot parameter. This is done to avoid LSM registration clashes in case of more than one bult-in module. User can choose a security module to enable at boot. If no security= boot parameter is specified, only the first LSM asking for registration will be loaded. An invalid security module name will be treated as if no module has been chosen. LSM modules must check now if they are allowed to register by calling security_module_enable(ops) first. Modify SELinux and SMACK to do so. Do not let SMACK register smackfs if it was not chosen on boot. Smackfs assumes that smack hooks are registered and the initial task security setup (swapper->security) is done.

2008-04-18[NET]: Fix and allocate less memory for ->priv'less netdevicesAlexey Dobriyan
This patch effectively reverts commit d0498d9ae1a5cebac363e38907266d5cd2eedf89 aka "[NET]: Do not allocate unneeded memory for dev->priv alignment." It was found to be buggy because of final unconditional += NETDEV_ALIGN_CONST removal. For example, for sizeof(struct net_device) being 2048 bytes, "alloc_size" was also 2048 bytes, but allocator with debugging options turned on started giving out !32-byte aligned memory resulting in redzones overwrites. Patch does small optimization in ->priv'less case: bumping size to next 32-byte boundary was always done to ensure ->priv will also be aligned. But, no ->priv, no need to do that.

2008-04-18libata: fix boot panic with SATAPI devices on non-SFF HBAsJames Bottomley
The kernel now panics reliably on boot if you have a SATAPI device connected. The problem was introduced by the libata merge trying to pull out all the SFF code into a separate module. Unfortunately, if you're a satapi device you usually need to call atapi_request_sense, which has a bare invocation of a SFF callback which is NULL on non-SFF HBAs. Fix this by making the call conditional. Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
