Alexander Aring says: ==================== 6lowpan: address uncompression fixes The current implementation to uncompress addresses in a 6lowpan header is completely broken. This patch series fixes the parsing of addresses in a 6lowpan header. It contains a major rewrite of the uncompress address function to parse the address in a correct way. Tested with the ravenusbstick(contiki 6LoWPAN stack) and beaglebone (linux 6LoWPAN Stack) on the other side. The linux side contains all possible addresses for the uncompression cases. Then I type a ping6 for each case and lookup in wireshark and dmesg the correct reconstruction. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2013-08-206lowpan: lowpan_uncompress_addr with address_modeAlexander Aring
This patch drops the pre and postcount calculation from the lowpan_uncompress_addr function.We use instead a switch/case over address_mode value. The original implementation has several bugs in this function and it was hard to decrypt how it works. To make it maintainable and fix these bugs this patch basically reimplements lowpan_uncompress_addr from scratch. A list of bugs we found in the current implementation: 1) Properly support uncompression of short-address based IPv6 addresses (instead of basically copying garbage) 2) Fix use and uncompression of long-addresses based IPv6 addresses 3) Add missing ff:fe00 in the case of SAM/DAM = 2 and M = 0 Signed-off-by: Alexander Aring <alex.aring@gmail.com> Reviewed-by: Werner Almesberger <werner@almesberger.net> Signed-off-by: David S.

2013-08-206lowpan: Fix fragmentation with link-local compressed addressesDavid Hauweele
When a new 6lowpan fragment is received, a skbuff is allocated for the reassembled packet. However when a 6lowpan packet compresses link-local addresses based on link-layer addresses, the processing function relies on the skb mac control block to find the related link-layer address. This patch copies the control block from the first fragment into the newly allocated skb to keep a trace of the link-layer addresses in case of a link-local compressed address.

2013-08-16Fix TLB gather virtual address range invalidation corner casesLinus Torvalds
Ben Tebulin reported: "Since v3.7.2 on two independent machines a very specific Git repository fails in 9/10 cases on git-fsck due to an SHA1/memory failures. This only occurs on a very specific repository and can be reproduced stably on two independent laptops. Git mailing list ran out of ideas and for me this looks like some very exotic kernel issue" and bisected the failure to the backport of commit 53a59fc67f97 ("mm: limit mmu_gather batching to fix soft lockups on !CONFIG_PREEMPT"). That commit itself is not actually buggy, but what it does is to make it much more likely to hit the partial TLB invalidation case, since it introduces a new case in tlb_next_batch() that previously only ever happened when running out of memory. The real bug is that the TLB gather virtual memory range setup is subtly buggered. It was introduced in commit 597e1c3580b7 ("mm/mmu_gather: enable tlb flush range in generic mmu_gather"), and the range handling was already fixed at least once in commit e6c495a96ce0 ("mm: fix the TLB range flushed when __tlb_remove_page() runs out of slots"), but that fix was not complete. The problem with the TLB gather virtual address range is that it isn't set up by the initial tlb_gather_mmu() initialization (which didn't get the TLB range information), but it is set up ad-hoc later by the functions that actually flush the TLB. And so any such case that forgot to update the TLB range entries would potentially miss TLB invalidates. Rather than try to figure out exactly which particular ad-hoc range setup was missing (I personally suspect it's the hugetlb case in zap_huge_pmd(), which didn't have the same logic as zap_pte_range() did), this patch just gets rid of the problem at the source: make the TLB range information available to tlb_gather_mmu(), and initialize it when initializing all the other tlb gather fields. This makes the patch larger, but conceptually much simpler. And the end result is much more understandable; even if you want to play games with partial ranges when invalidating the TLB contents in chunks, now the range information is always there, and anybody who doesn't want to bother with it won't introduce subtle bugs. Ben verified that this fixes his problem.

2013-08-15net/mlx5_core: Support MANAGE_PAGES and QUERY_PAGES firmware command changesMoshe Lazer
In the previous QUERY_PAGES command version we used one command to get the required amount of boot, init and post init pages. The new version uses the op_mod field to specify whether the query is for the required amount of boot, init or post init pages. In addition the output field size for the required amount of pages increased from 16 to 32 bits. In MANAGE_PAGES command the input_num_entries and output_num_entries fields sizes changed from 16 to 32 bits and the PAS tables offset changed to 0x10. In the pages request event the num_pages field also changed to 32 bits. In the HCA-capabilities-layout the size and location of max_qp_mcg field has been changed to support 24 bits. This patch isn't compatible with firmware versions < 5; however, it turns out that the first GA firmware we will publish will not support previous versions so this should be OK.

2013-08-15tun: signedness bug in tun_get_user()Dan Carpenter
The recent fix d9bf5f1309 "tun: compare with 0 instead of total_len" is not totally correct. Because "len" and "sizeof()" are size_t type, that means they are never less than zero.
