2011-03-30bridge: mcast snooping, fix length check of snooped MLDv1/2Linus Lüssing
"len = ntohs(ip6h->payload_len)" does not include the length of the ipv6 header itself, which the rest of this function assumes, though. This leads to a length check less restrictive as it should be in the following line for one thing. For another, it very likely leads to an integer underrun when substracting the offset and therefore to a very high new value of 'len' due to its unsignedness. This will ultimately lead to the pskb_trim_rcsum() practically never being called, even in the cases where it should. Signed-off-by: Linus Lüssing <linus.luessing@web.de> Signed-off-by: David S.

2011-03-30net: gre: provide multicast mappings for ipv4 and ipv6Timo Teräs
My commit 6d55cb91a0020ac0 (gre: fix hard header destination address checking) broke multicast. The reason is that ip_gre used to get ipgre_header() calls with zero destination if we have NOARP or multicast destination. Instead the actual target was decided at ipgre_tunnel_xmit() time based on per-protocol dissection. Instead of allowing the "abuse" of ->header() calls with invalid destination, this creates multicast mappings for ip_gre. This also fixes "ip neigh show nud noarp" to display the proper multicast mappings used by the gre device.

2011-03-30nilfs2: fix data loss in mmap page write for hole blocksRyusuke Konishi
From the result of a function test of mmap, mmap write to shared pages turned out to be broken for hole blocks. It doesn't write out filled blocks and the data will be lost after umount. This is due to a bug that the target file is not queued for log writer when filling hole blocks. Also, nilfs_page_mkwrite function exits normal code path even after successfully filled hole blocks due to a change of block_page_mkwrite function; just after nilfs was merged into the mainline, block_page_mkwrite() started to return VM_FAULT_LOCKED instead of zero by the patch "mm: close page_mkwrite races" (commit: b827e496c893de0c). The current nilfs_page_mkwrite() is not handling this value properly. This corrects nilfs_page_mkwrite() and will resolve the data loss problem in mmap write.

2011-03-30powerpc: Fix accounting of softirq time when idleAnton Blanchard
commit cf9efce0ce31 (powerpc: Account time using timebase rather than PURR) used in_irq() to detect if the time was spent in interrupt processing. This only catches hardirq context so if we are in softirq context and in the idle loop we end up accounting it as idle time. If we instead use in_interrupt() we catch both softirq and hardirq time. The issue was found when running a network intensive workload. top showed the following: 0.0%us, 1.1%sy, 0.0%ni, 85.7%id, 0.0%wa, 9.9%hi, 3.3%si, 0.0%st 85.7% idle. But this was wildly different to the perf events data. To confirm the suspicion I ran something to keep the core busy: # yes > /dev/null & 8.2%us, 0.0%sy, 0.0%ni, 0.0%id, 0.0%wa, 10.3%hi, 81.4%si, 0.0%st We only got 8.2% of the CPU for the userspace task and softirq has shot up to 81.4%. With the patch below top shows the correct stats: 0.0%us, 0.0%sy, 0.0%ni, 5.3%id, 0.0%wa, 13.3%hi, 81.3%si, 0.0%st Signed-off-by: Anton Blanchard <anton@samba.org> Cc: stable@kernel.org Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

commit 79f26c268ebad29bd75d078cfc09d3d82b30ccbd (powerpc: platforms/pseries irq_data conversion) pushed irq_desc down into many functions, dererencing the descriptor irq field as late as possible. But it incorrectly passed a linix virtural irq number to RTAS, resulting in the interrupt not being disabled and possibly other bad things, such as another interrupt being disabled and/or a checkstop. In addition this missed the point of xics_mask_unknown_vec and the seperation of xics_mask_real_irq from xics_mask_irq. When xics_mask_unknown_vec is called it's because the hardware delivered an irq source for which we have no linux irq allocated, and thefore we can not have an irq_desc allocated. Revert xics_mask_real_irq to its prior version, naming the argument hwirq to highlight the difference.

Uwe Kleine-König reported: while working on an defconfig (arm/mx27) I noticed that just updating it[1] results in removing CONFIG_EEPROM_AT24=y. The reason is that since commit v2.6.36-5965-g5f2365d (misc devices: do not enable by default) MISC_DEVICES isn't enabled anymore by default. So all defconfigs that have CONFIG_SOME_SYMBOL=y (or =m) (with SOME_SYMBOL depending on MISC_DEVICES) but not CONFIG_MISC_DEVICES=y suffer from the same problem.

2011-03-29x86, mtrr, pat: Fix one cpu getting out of sync during resumeSuresh Siddha
On laptops with core i5/i7, there were reports that after resume graphics workloads were performing poorly on a specific AP, while the other cpu's were ok. This was observed on a 32bit kernel specifically. Debug showed that the PAT init was not happening on that AP during resume and hence it contributing to the poor workload performance on that cpu. On this system, resume flow looked like this: 1. BP starts the resume sequence and we reinit BP's MTRR's/PAT early on using mtrr_bp_restore() 2. Resume sequence brings all AP's online 3. Resume sequence now kicks off the MTRR reinit on all the AP's. 4. For some reason, between point 2 and 3, we moved from BP to one of the AP's. My guess is that printk() during resume sequence is contributing to this. We don't see similar behavior with the 64bit kernel but there is no guarantee that at this point the remaining resume sequence (after AP's bringup) has to happen on BP. 5. set_mtrr() was assuming that we are still on BP and skipped the MTRR/PAT init on that cpu (because of 1 above) 6. But we were on an AP and this led to not reprogramming PAT on this cpu leading to bad performance. Fix this by doing unconditional mtrr_if->set_all() in set_mtrr() during MTRR/PAT init. This might be unnecessary if we are still running on BP. But it is of no harm and will guarantee that after resume, all the cpu's will be in sync with respect to the MTRR/PAT registers.

2011-03-29iwl3945: disable hw scan by defaultStanislaw Gruszka
After new NetworkManager 0.8.996 changes, hardware scanning is causing microcode errors as reported here: https://bugzilla.redhat.com/show_bug.cgi?id=683571 and sometimes kernel crashes: https://bugzilla.redhat.com/show_bug.cgi?id=688252 Also with hw scan there are very bad performance on some systems as reported here: https://bugzilla.redhat.com/show_bug.cgi?id=671366 Since Intel no longer supports 3945, there is no chance to get proper firmware fixes, we need workaround problems by disable hardware scanning by default.
