Add a module parameter "sysbus_parity" to allow forcing system bus parity error checking on or off. Also add support to automatically disable system bus parity errors for processors which do not support it. If the sysbus_parity parameter is specified, sysbus parity detection will be forced on or off. If it is not specified, the driver will attempt to look at the CPU identifier string and determine if the CPU supports system bus parity. A blacklist was used instead of a whitelist so that system bus parity would be enabled by default and to minimize the chances of breaking things for those people already using the driver which for some reason have a processor that does not have a valid CPU identifier string.

Switch add_entropy_words to a byte-oriented interface, eliminating numerous casts and byte/word size rounding issues. This also reduces the overall bit/byte/word confusion in this code. We now mix a byte at a time into the word-based pool. This takes four times as many iterations, but should be negligible compared to hashing overhead. This also increases our pool churn, which adds some depth against some theoretical failure modes. The function name is changed to emphasize pool mixing and deemphasize entropy (the samples mixed in may not contain any). extract is added to the core function to make it clear that it extracts from the pool.

The urandom output pool (ie the fast path) fits in one cacheline, so this is pretty unnecessary. Further, the output path has already fetched the entire pool to hash it before calling in here.

At each extraction, we change (poolbits / 16) + 32 bits in the pool, or 96 bits in the case of the secondary pools. Thus, a brute-force backtracking attack on the pool state is less difficult than breaking the hash. In certain cases, this difficulty may be is reduced to 2^64 iterations. Instead, hash the entire pool in one go, then feedback the whole hash (160 bits) in one go. This will make backtracking at least as hard as inverting the hash.

Permit the use of partitions with network block devices (NBD). A new parameter is introduced to define how many partition we want to be able to manage per network block device. This parameter is "max_part". For instance, to manage 63 partitions / loop device, we will do: [on the server side] # nbd-server 1234 /dev/sdb [on the client side] # modprobe nbd max_part=63 # ls -l /dev/nbd* brw-rw---- 1 root disk 43, 0 2008-03-25 11:14 /dev/nbd0 brw-rw---- 1 root disk 43, 64 2008-03-25 11:11 /dev/nbd1 brw-rw---- 1 root disk 43, 640 2008-03-25 11:11 /dev/nbd10 brw-rw---- 1 root disk 43, 704 2008-03-25 11:11 /dev/nbd11 brw-rw---- 1 root disk 43, 768 2008-03-25 11:11 /dev/nbd12 brw-rw---- 1 root disk 43, 832 2008-03-25 11:11 /dev/nbd13 brw-rw---- 1 root disk 43, 896 2008-03-25 11:11 /dev/nbd14 brw-rw---- 1 root disk 43, 960 2008-03-25 11:11 /dev/nbd15 brw-rw---- 1 root disk 43, 128 2008-03-25 11:11 /dev/nbd2 brw-rw---- 1 root disk 43, 192 2008-03-25 11:11 /dev/nbd3 brw-rw---- 1 root disk 43, 256 2008-03-25 11:11 /dev/nbd4 brw-rw---- 1 root disk 43, 320 2008-03-25 11:11 /dev/nbd5 brw-rw---- 1 root disk 43, 384 2008-03-25 11:11 /dev/nbd6 brw-rw---- 1 root disk 43, 448 2008-03-25 11:11 /dev/nbd7 brw-rw---- 1 root disk 43, 512 2008-03-25 11:11 /dev/nbd8 brw-rw---- 1 root disk 43, 576 2008-03-25 11:11 /dev/nbd9 # nbd-client localhost 1234 /dev/nbd0 Negotiation: ..size = 80418240KB bs=1024, sz=80418240 -------NOTE, RFC: partition table is not automatically read.

This patch allows Network Block Device to be mounted locally (nbd-client to nbd-server over 127.0.0.1). It creates a kthread to avoid the deadlock described in NBD tools documentation. So, if nbd-client hangs waiting for pages, the kblockd thread can continue its work and free pages. I have tested the patch to verify that it avoids the hang that always occurs when writing to a localhost nbd connection. I have also tested to verify that no performance degradation results from the additional thread and queue. Patch originally from Laurent Vivier.

When reading from/writing to some table, a root, which this table came from, may affect this table's permissions, depending on who is working with the table. The core hunk is at the bottom of this patch. All the rest is just pushing the ctl_table_root argument up to the sysctl_perm() function. This will be mostly (only?) used in the net sysctls.

The do_sysctl_strategy isn't used outside kernel/sysctl.c, so this can be static and without a prototype in header.

Many (most of) sysctls do not have a per-container sense. E.g. kernel.print_fatal_signals, vm.panic_on_oom, net.core.netdev_budget and so on and so forth. Besides, tuning then from inside a container is not even secure. On the other hand, hiding them completely from the container's tasks sometimes causes user-space to stop working. When developing net sysctl, the common practice was to duplicate a table and drop the write bits in table->mode, but this approach was not very elegant, lead to excessive memory consumption and was not suitable in general. Here's the alternative solution. To facilitate the per-container sysctls ctl_table_root-s were introduced. Each root contains a list of ctl_table_header-s that are visible to different namespaces. The idea of this set is to add the permissions() callback on the ctl_table_root to allow ctl root limit permissions to the same ctl_table-s. The main user of this functionality is the net-namespaces code, but later this will (should) be used by more and more namespaces, containers and control groups. Actually, this idea's core is in a single hunk in the third patch. First two patches are cleanups for sysctl code, while the third one mostly extends the arguments set of some sysctl functions. This patch: These ->read and ->write callbacks act in a very similar way, so merge these paths to reduce the number of places to patch later and shrink the .text size (a bit).
