* [NET]: Fix module reference counts for loadable protocol modulesFrank Filz2005-09-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I have been experimenting with loadable protocol modules, and ran into several issues with module reference counting. The first issue was that __module_get failed at the BUG_ON check at the top of the routine (checking that my module reference count was not zero) when I created the first socket. When sk_alloc() is called, my module reference count was still 0. When I looked at why sctp didn't have this problem, I discovered that sctp creates a control socket during module init (when the module ref count is not 0), which keeps the reference count non-zero. This section has been updated to address the point Stephen raised about checking the return value of try_module_get(). The next problem arose when my socket init routine returned an error. This resulted in my module reference count being decremented below 0. My socket ops->release routine was also being called. The issue here is that sock_release() calls the ops->release routine and decrements the ref count if sock->ops is not NULL. Since the socket probably didn't get correctly initialized, this should not be done, so we will set sock->ops to NULL because we will not call try_module_get(). While searching for another bug, I also noticed that sys_accept() has a possibility of doing a module_put() when it did not do an __module_get so I re-ordered the call to security_socket_accept().

* [NET]: Reorder some hot fields of struct net_deviceEric Dumazet2005-09-27
| | | | | | | | | | | | | | | | | | | | | | | Place them on separate cache lines in SMP to lower memory bouncing between multiple CPU accessing the device. - One part is mostly used on receive path (including eth_type_trans()) (poll_list, poll, quota, weight, last_rx, dev_addr, broadcast) - One part is mostly used on queue transmit path (qdisc) (queue_lock, qdisc, qdisc_sleeping, qdisc_list, tx_queue_len) - One part is mostly used on xmit path (device) (xmit_lock, xmit_lock_owner, priv, hard_start_xmit, trans_start) 'features' is placed outside of these hot points, in a location that may be shared by all cpus (because mostly read) name_hlist is moved close to name[IFNAMSIZ] to speedup __dev_get_by_name() Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S.

| * [SPARC64]: Do not do TLB pre-filling any more.David S. Miller2005-09-26
| | | | | | | | | | | | | | | | | | | | | | In order to do it correctly on UltraSPARC-III+ and later we'd need to add some complicated code to set the TAG access extension register before loading the TLB. Since this optimization gives questionable gains, it's best to just remove it for now instead of adding the fix for Ultra-III+ Signed-off-by: David S. Miller <davem@davemloft.net>
| * [SPARC64]: Simplify Spitfire D-cache page flush.David S. Miller2005-09-26

| * [SPARC64]: Probe D/I/E-cache config and use.David S. Miller2005-09-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At boot time, determine the D-cache, I-cache and E-cache size and line-size. Use them in cache flushes when appropriate. This change was motivated by discovering that the D-cache on UltraSparc-IIIi and later are 64K not 32K, and the flushes done by the Cheetah error handlers were assuming a 32K size. There are still some pieces of code that are hard coding things and will need to be fixed up at some point. While we're here, fix the D-cache and I-cache parity error handlers to run with interrupts disabled, and when the trap occurs at trap level > 1 log the event via a counter displayed in /proc/cpuinfo.

| * [SPARC64]: Add CONFIG_DEBUG_PAGEALLOC support.David S. Miller2005-09-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The trick is that we do the kernel linear mapping TLB miss starting with an instruction sequence like this: ba,pt %xcc, kvmap_load xor %g2, %g4, %g5 succeeded by an instruction sequence which performs a full page table walk starting at swapper_pg_dir. We first take over the trap table from the firmware. Then, using this constant PTE generation for the linear mapping area above, we build the kernel page tables for the linear mapping. After this is setup, we patch that branch above into a "nop", which will cause TLB misses to fall through to the full page table walk. With this, the page unmapping for CONFIG_DEBUG_PAGEALLOC is trivial. Signed-off-by: David S. Miller <davem@davemloft.net>

What we do now is the following in position independant assembler: chosen_node = prom_finddevice("/chosen"); prom_mmu_ihandle_cache = prom_getint(chosen_node, "mmu"); vaddr = 4MB_ALIGN(current_text_addr()); prom_translate(vaddr, &paddr_high, &paddr_low, &mode); prom_boot_mapping_mode = mode; prom_boot_mapping_phys_high = paddr_high; prom_boot_mapping_phys_low = paddr_low; prom_map(-1, 8 * 1024 * 1024, KERNBASE, paddr_low); and that replaces the massive amount of by-hand TLB probing and programming we used to do here. The new code should also handle properly the case where the kernel is mapped at the correct address already (think: future kexec support). Consequently, the bulk of remap_kernel() dies as does the entirety of arch/sparc64/prom/map.S We try to share some strings in the PROM library with the ones used at bootup, and while we're here mark input strings to oplib.h routines with "const" when appropriate. There are many more simplifications now possible. For one thing, we can consolidate the two copies we now have of a lot of cpu setup code sitting in head.S and trampoline.S. This is a significant step towards CONFIG_DEBUG_PAGEALLOC support. Signed-off-by: David S. Miller <davem@davemloft.net>

| * [SPARC64]: Remove unnecessary paging_init() cruft.David S. Miller2005-09-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Because we don't access the PAGE_OFFSET linear mappings any longer before we take over the trap table from the firmware, we don't need to load dummy mappings there into the TLB and we don't need the bootmap_base hack any longer either. While we are here, check for a larger than 8MB kernel and halt the boot with an error message. We know that doesn't work, so instead of failing mysteriously we should let the user know exactly what's wrong. Signed-off-by: David S. Miller <davem@davemloft.net>
| * [SPARC64]: Do not allocate OBP page tables using bootmemDavid S. Miller2005-09-22
| | | | | | | | | | | | | | | | | | | | | | | | | | Just allocate them physically starting from the end of the kernel image. This incredibly simplifies our MM bootstrap in that we don't need any mappings in the linear PAGE_OFFSET area working in order to bootstrap ourselves and take over the trap table from the firmware. Many further simplifications are possible now, and this also sets the stage for CONFIG_DEBUG_PAGEALLOC support. Signed-off-by: David S. Miller <davem@davemloft.net>

| * [SPARC64]: Remove ktlb.S instruction patching.David S. Miller2005-09-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This was kind of ugly, and actually buggy. The bug was that we didn't handle a machine with memory starting > 4GB. If the 'prompmd' was allocated in physical memory > 4GB we'd croak because the obp_iaddr_patch and obp_daddr_patch things only supported a 32-bit physical address. So fix this by just loading the appropriate values from two variables in the kernel image, which is locked into the TLB and thus accesses to them can't cause a recursive TLB miss.

| * | [TG3]: 5780 PHY fixesMichael Chan2005-09-27

MAC_RX_MODE reset must be done before setting up the MAC_MODE register on 5705_PLUS chips or the chip will stop receiving after a while. The MAC_RX_MODE reset is needed to prevent intermittently losing the first receive packet on serdes chips. 2. Skip MAC loopback test on 5780 because of hardware errata. Normal traffic including PHY loopback is not affected by the errata. 3. PHY loopback fails intermittently on 5708S and this is fixed by putting the PHY in loopback mode first before programming the MAC mode register. A MAC_RX_MODE reset is also added. 4. Return -EINVAL in tg3_nway_reset() if device is in TBI mode. Allow nway_reset if 5780S is in parallel detect mode. 5. Add missing PHY IDs in KNOWN_PHY_ID() macro.
