2005-08-29[NETFILTER]: Rename skb_ip_make_writable() to skb_make_writable()Harald Welte
There is nothing IPv4-specific in it. In fact, it was already used by IPv6, too... Upcoming nfnetlink_queue code will use it for any kind of packet. Signed-off-by: Harald Welte <laforge@netfilter.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2005-08-29[NET]: Kill skb->real_devDavid S. Miller
Bonding just wants the device before the skb_bond() decapsulation occurs, so simply pass that original device into packet_type->func() as an argument. It remains to be seen whether we can use this same exact thing to get rid of skb->input_dev as well. Signed-off-by: David S. Miller <davem@davemloft.net>

2005-08-29[NETFILTER]: Add ctnetlink subsystemHarald Welte
Add ctnetlink subsystem for userspace-access to ip_conntrack table. This allows reading and updating of existing entries, as well as creating new ones (and new expect's) via nfnetlink. Please note the 'strange' byte order: nfattr (tag+length) are in host byte order, while the payload is always guaranteed to be in network byte order. This allows a simple userspace process to encapsulate netlink messages into arch-independent udp packets by just processing/swapping the headers and not knowing anything about the actual payload.

2005-08-29[NET]: Remove HIPPI private from skbuff.hStephen Hemminger
This removes the private element from skbuff, that is only used by HIPPI. Instead it uses skb->cb[] to hold the additional data that is needed in the output path from hard_header to device driver. PS: The only qdisc that might potentially corrupt this cb[] is if netem was used over HIPPI. I will take care of that by fixing netem to use skb->stamp. I don't expect many users of netem over HIPPI Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2005-08-29[NETFITLER]: Add nfnetlink layer.Harald Welte

2005-08-29[NETFILTER]: connection tracking event notifiersHarald Welte
This adds a notifier chain based event mechanism for ip_conntrack state changes. As opposed to the previous implementations in patch-o-matic, we do no longer need a field in the skb to achieve this.

2005-08-29[NET]: Kill skb->listDavid S. Miller
Remove the "list" member of struct sk_buff, as it is entirely redundant. All SKB list removal callers know which list the SKB is on, so storing this in sk_buff does nothing other than taking up some space. Two tricky bits were SCTP, which I took care of, and two ATM drivers which Francois Romieu <romieu@fr.zoreil.com> fixed up. Signed-off-by: David S.

2005-08-29[NETFILTER]: reduce netfilter sk_buff enlargementHarald Welte
As discussed at netconf'05, we're trying to save every bit in sk_buff. The patch below makes sk_buff 8 bytes smaller. I did some basic testing on my notebook and it seems to work. The only real in-tree user of nfcache was IPVS, who only needs a single bit. Unfortunately I couldn't find some other free bit in sk_buff to stuff that bit into, so I introduced a separate field for them. Maybe the IPVS guys can resolve that to further save space. Initially I wanted to shrink pkt_type to three bits (PACKET_HOST and alike are only 6 values defined), but unfortunately the bluetooth code overloads pkt_type :( The conntrack-event-api (out-of-tree) uses nfcache, but Rusty just came up with a way how to do it without any skb fields, so it's safe to remove it. - remove all never-implemented 'nfcache' code - don't have ipvs code abuse 'nfcache' field. currently get's their own compile-conditional skb->ipvs_property field. IPVS maintainers can decide to move this bit elswhere, but nfcache needs to die. - remove skb->nfcache field to save 4 bytes - move skb->nfctinfo into three unused bits to save further 4 bytes Signed-off-by: Harald Welte <laforge@netfilter.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2005-08-29[SPARC64]: More fully work around Spitfire Errata 51.David S. Miller
It appears that a memory barrier soon after a mispredicted branch, not just in the delay slot, can cause the hang condition of this cpu errata. So move them out-of-line, and explicitly put them into a "branch always, predict taken" delay slot which should fully kill this problem. Signed-off-by: David S. Miller <davem@davemloft.net>
2005-08-29[SPARC64]: Make debugging spinlocks usable again.David S. Miller
When the spinlock routines were moved out of line into kernel/spinlock.c this made it so that the debugging spinlocks record lock acquisition program counts in the kernel/spinlock.c functions not in their callers. This makes the debugging info kind of useless. So record the correct caller's program counter and now this feature is useful once more. Signed-off-by: David S. Miller <davem@davemloft.net>

2005-08-29[SPARC64]: Revamp Spitfire error trap handling.David S. Miller
Current uncorrectable error handling was poor enough that the processor could just loop taking the same trap over and over again. Fix things up so that we at least get a log message and perhaps even some register state. In the process, much consolidation became possible, particularly with the correctable error handler. Prefix assembler and C function names with "spitfire" to indicate that these are for Ultra-I/II/IIi/IIe only. More work is needed to make these routines robust and featureful to the level of the Ultra-III error handlers. Signed-off-by: David S. Miller <davem@davemloft.net>
2005-08-29[PATCH] mod_devicetable.h fixesAl Viro
* ieee1394_device_id has kernel_ulong_t field after an odd number of __u32 ones. Since mod_devicetable.h is included both from kernel and from host build helper, we may be in trouble if we are building on 32bit host for 64bit target - userland sees unsigned long long, kernel sees unsigned long and while their sizes match, alignments might not. Fixed by forcing alignment. Fortunately, almost nobody else needs that - the rest of such fields is naturally aligned as it is. * of_device_id has void * in it. Host userland helpers need kernel_ulong_t instead, since their void * might have nothing to do with the kernel one. Fixed in the same way it's done for similar problems in pcmcia_device_id (ifdef __KERNEL__). * pcmcia_device_id has the same problem as ieee1394_device_id. Fixed the same way.

2005-08-29[PATCH] Dynamic hugepage addresses for ppc64David Gibson
Paulus, I think this is now a reasonable candidate for the post-2.6.13 queue. Relax address restrictions for hugepages on ppc64 Presently, 64-bit applications on ppc64 may only use hugepages in the address region from 1-1.5T. Furthermore, if hugepages are enabled in the kernel config, they may only use hugepages and never normal pages in this area. This patch relaxes this restriction, allowing any address to be used with hugepages, but with a 1TB granularity. That is if you map a hugepage anywhere in the region 1TB-2TB, that entire area will be reserved exclusively for hugepages for the remainder of the process's lifetime. This works analagously to hugepages in 32-bit applications, where hugepages can be mapped anywhere, but with 256MB (mmu segment) granularity. This patch applies on top of the four level pagetable patch (http://patchwork.ozlabs.org/linuxppc64/patch?id=1936).

2005-08-29[PATCH] ppc64: allow xmon=offOlaf Hering
If both CONFIG_XMON and CONFIG_XMON_DEFAULT is enabled in the .config, there is no way to disable xmon again. setup_system calls first xmon_init, later parse_early_param.

2005-08-29[PATCH] ppc64: Remove CONFIG_MSCHUNKSMichael Ellerman
We can now remove CONFIG_MSCHUNKS as it doesn't do anything interesting anymore. The only macro in abs_addr.h which is called by non-iSeries code is phys_to_abs(), so remove the other dummy implementations, and we add a firmware feature check to phys_to_abs().

2005-08-29[PATCH] ppc64: Remove redundant abs_to_phys() macroMichael Ellerman
abs_to_phys() is a macro that turns out to do nothing, and also has the unfortunate property that it's not the inverse of phys_to_abs() on iSeries. The following is for my benefit as much as everyone else. With CONFIG_MSCHUNKS enabled, the lmb code is changed such that it keeps a physbase variable for each lmb region. This is used to take the possibly discontiguous lmb regions and present them as a contiguous address space beginning from zero. In this context each lmb region's base address is its "absolute" base address, and its physbase is it's "physical" address (from Linux's point of view). The abs_to_phys() macro does the mapping from "absolute" to "physical". Note: This is not related to the iSeries mapping of physical to absolute (ie. Hypervisor) addresses which is maintained with the msChunks structure. And the msChunks structure is not controlled via CONFIG_MSCHUNKS. Once upon a time you could compile for non-iSeries with CONFIG_MSCHUNKS enabled. But these days CONFIG_MSCHUNKS depends on CONFIG_PPC_ISERIES, so for non-iSeries code abs_to_phys() is a no-op. On iSeries we always have one lmb region which spans from 0 to systemcfg->physicalMemorySize (arch/ppc64/kernel/iSeries_setup.c line 383). This region has a base (ie. absolute) address of 0, and a physbase address of 0 (as calculated in lmb_analyze() (arch/ppc64/kernel/lmb.c line 144)). On iSeries, abs_to_phys(aa) is defined as lmb_abs_to_phys(aa), which finds the lmb region containing aa (and there's only one, ie. 0), and then does: return lmb.memory.region[0].physbase + (aa - lmb.memory.region[0].base) physbase == base == 0, so you're left with "return aa". So remove abs_to_phys(), and lmb_abs_to_phys() which is the implementation of abs_to_phys() for iSeries.

2005-08-29[PATCH] ppc64: msChunks cleanupsMichael Ellerman
Chunks are 256KB, so use constants for the size/shift/mask, rather than getting them from the msChunks struct. The iSeries debugger (??) might still need access to the values in the msChunks struct, so we keep them around for now, but set them from the constant values. Replace msChunks_entry typedef with regular u32. Simplify msChunks_alloc() to manipulate klimit directly, rather than via a parameter.
