* ppp_generic: use stats from net_device structurePaulius Zaleckas2008-04-23
| | | | | | | | | | Use stats which now is in the net_device instead of one declared in ppp structure. Kill ppp_net_stats function, because by default it is used identical internal_stats function from net/core/dev.c Signed-of-by: Paulius Zaleckas <paulius.zaleckas@teltonika.lt> Signed-off-by: David S.

* leds: Do not guard NEW_LEDS with HAS_IOMEMDavid S. Miller2008-04-23
| | | | | | | | | | | | | The LEDS infrastructure itself does not require anything that a platform dependant upon HAS_IOMEM. The individual drivers do, but they are properly guarded with the necessary platform dependencies. One can even imagine a hypervisor based LED driver that a platform without HAS_IOMEM might have.

* [IPSEC]: Fix catch-22 with algorithm IDs above 31Herbert Xu2008-04-22
| | | | | | | | | | | | | | | | | | | | | | | As it stands it's impossible to use any authentication algorithms with an ID above 31 portably. It just happens to work on x86 but fails miserably on ppc64. The reason is that we're using a bit mask to check the algorithm ID but the mask is only 32 bits wide. After looking at how this is used in the field, I have concluded that in the long term we should phase out state matching by IDs because this is made superfluous by the reqid feature. For current applications, the best solution IMHO is to allow all algorithms when the bit masks are all ~0. The following patch does exactly that. This bug was identified by IBM when testing on the ppc64 platform using the NULL authentication algorithm which has an ID of 251.

| | | | | | | | | | | | | | 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.

* tg3: 5701 DMA corruption fixMatt Carlson2008-04-19
| | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

In net/netlabel/netlabel_unlabeled.c::netlbl_unlabel_staticlist_gen() the function is called, but the return value is never checked. If it returns NULL then we'll deref a NULL pointer on the very next line. I checked the callers, and I don't think this can actually happen today, but code changes over time and in the future it might happen and it does no harm to be defensive and check for the failure, so that if/when it happens we'll fail gracefully instead of crashing.
