* filter: add XOR instruction for use with X/KDaniel Borkmann2012-09-241-0/+3
| | | | | | | | | | | | SKF_AD_ALU_XOR_X has been added a while ago, but as an 'ancillary' operation that is invoked through a negative offset in K within BPF load operations. Since BPF_MOD has recently been added, BPF_XOR should also be part of the common ALU operations. Removing SKF_AD_ALU_XOR_X might not be an option since this is exposed to user space.

* net: use a per task frag allocatorEric Dumazet2012-09-241-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We currently use a per socket order-0 page cache for tcp_sendmsg() operations. This page is used to build fragments for skbs. Its done to increase probability of coalescing small write() into single segments in skbs still in write queue (not yet sent) But it wastes a lot of memory for applications handling many mostly idle sockets, since each socket holds one page in sk->sk_sndmsg_page Its also quite inefficient to build TSO 64KB packets, because we need about 16 pages per skb on arches where PAGE_SIZE = 4096, so we hit page allocator more than wanted. This patch adds a per task frag allocator and uses bigger pages, if available. An automatic fallback is done in case of memory pressure. (up to 32768 bytes per frag, thats order-3 pages on x86) This increases TCP stream performance by 20% on loopback device, but also benefits on other network devices, since 8x less frags are mapped on transmit and unmapped on tx completion. Alexander Duyck mentioned a probable performance win on systems with IOMMU enabled. Its possible some SG enabled hardware cant cope with bigger fragments, but their ndo_start_xmit() should already handle this, splitting a fragment in sub fragments, since some arches have PAGE_SIZE=65536 Successfully tested on various ethernet devices.

You can notice that this batch contains a couple of fixes that may go to 3.6-rc but I don't consider them critical to push them: * The ipset fix for the /0 cidr case, which is triggered with one inconsistent command line invocation of ipset. * The nfnetlink_queue maximum packet length supported since it requires the new NFQA_CAP_LEN attribute to provide a full workaround for the described problem. ==================== Signed-off-by: David S.

| * netfilter: nfnetlink_queue: add NFQA_CAP_LEN attributePablo Neira Ayuso2012-09-241-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the NFQA_CAP_LEN attribute that allows us to know what is the real packet size from user-space (even if we decided to retrieve just a few bytes from the packet instead of all of it). Security software that inspects packets should always check for this new attribute to make sure that it is inspecting the entire packet. This also helps to provide a workaround for the problem described in: http://marc.info/?l=netfilter-devel&m=134519473212536&w=2 Original idea from Florian Westphal.

| * netfilter: nf_ct_ftp: add sequence tracking pickup facility for injected entriesPablo Neira Ayuso2012-09-241-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch allows the FTP helper to pickup the sequence tracking from the first packet seen. This is useful to fix the breakage of the first FTP command after the failover while using conntrackd to synchronize states. The seq_aft_nl_num field in struct nf_ct_ftp_info has been shrinked to 16-bits (enough for what it does), so we can use the remaining 16-bits to store the flags while using the same size for the private FTP helper data.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, if you want to do something like: "match Monday, starting 23:00, for two hours" You need two rules, one for Mon 23:00 to 0:00 and one for Tue 0:00-1:00. The rule: --weekdays Mo --timestart 23:00 --timestop 01:00 looks correct, but it will first match on monday from midnight to 1 a.m. and then again for another hour from 23:00 onwards. This permits userspace to explicitly ignore the day transition and match for a single, continuous time period instead.

| | | | | | | | | | | | | | | | | | Add rtnl_link_ops to IPoIB, with the first usage being child device create/delete through them. Childs devices are now either legacy ones, created/deleted through the ipoib sysfs entries, or RTNL ones. Adding support for RTNL childs involved refactoring of ipoib_vlan_add which is now used by both the sysfs and the link_ops code. Also, added ndo_uninit entry to support calling unregister_netdevice_queue from the rtnl dellink entry. This required removal of calls to ipoib_dev_cleanup from the driver in flows which use unregister_netdevice, since the networking core will invoke ipoib_uninit which does exactly that.

This is caused by the (wrong) assumption that RFE in the Status Register is 1 iff there is no byte already ordered (via a dummy TX byte). This lead to the implementation of synchronized byte ordering, e.g.: Dummy-TX - RX - Dummy-TX - RX - ... But since RFE actually stays high after some Dummy-TX, it rather looks like: Dummy-TX - Dummy-TX - RX - Dummy-TX - RX - (RX) The last RX byte is clocked in by the bus controller, but ignored by the kernel when filling the userspace buffer. This patch fixes the issue by asking for RX via Dummy-TX asynchronously. Introducing a separate counter for TX bytes.

I had a hard time trying to disable it anyway ;-) The problem this time is lots of code assuming that a call to add_uevent_var() will guarantee that env->buflen > 0. This is not true if CONFIG_HOTPLUG is unset. So things like this end up overwriting env->envp_idx because the array index is -1: if (add_uevent_var(env, "MODALIAS=")) return -ENOMEM; len = input_print_modalias(&env->buf[env->buflen - 1], sizeof(env->buf) - env->buflen, dev, 0); Don't know what the best action is, given that there seem to be a *lot* of this around the kernel. This patch "fixes" the problem for me, but I don't know if it can be considered an appropriate fix. [ It is the correct fix for now, for 3.7 forcing CONFIG_HOTPLUG to always be on is the longterm fix, but it's too late for 3.6 and older kernels to resolve this that way - gregkh ] Reported-by: Fengguang Wu <fengguang.wu@intel.com> Signed-off-by: Bjørn Mork <bjorn@mork.no> Tested-by: Fengguang Wu <fengguang.wu@intel.com> Cc: stable <stable@vger.kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Since neither the UDP or the RDMA transport mechanism use dynamic slot allocation, we can skip grabbing the socket lock for those transports. Add a new rpc_xprt_op to allow switching between the TCP and UDP/RDMA case. Note that the NFSv4.1 back channel assigns the slot directly through rpc_run_bc_task, so we can ignore that case.

The current overflow checking is broken, resulting in Oopses on user-triggered nfs4_getfacl calls, and is opaque to the point where several attempts at fixing it have failed. This patch tries to clean up the code in addition to fixing the Oopses by ensuring that the overflow checks are performed in a single place (decode_getacl). If the overflow check failed, we will still be able to report the acl length, but at least we will no longer attempt to cache the acl or copy the truncated contents to user space.

At this point, NFS_COOKIEVERF seems to be more of an obfuscation than a helper, so the best thing would be to just get rid of it.

This patch sets this limits for Kirkwood and Dove which have smaller limits that the default. As a side note, this patch is an updated version of a patch sent some years ago: http://lists.infradead.org/pipermail/linux-arm-kernel/2010-June/017320.html which seems to have been lost.

Useful for mapping just a bio instead of a full request. - Regression fix from Hugh, fixing up a patch that went into the previous release cycle (and marked stable, too) attempting to prevent a loop in __getblk_slow(). - Updates to discard requests, fixing up the sizing and how we align them. Also a change to disallow merging of discard requests, since that doesn't really work properly yet. - A few drbd fixes. - Documentation updates. * 'for-linus' of git://git.kernel.dk/linux-block: block: replace __getblk_slow misfix by grow_dev_page fix drbd: Write all pages of the bitmap after an online resize drbd: Finish requests that completed while IO was frozen drbd: fix drbd wire compatibility for empty flushes Documentation: update tunable options in block/cfq-iosched.txt Documentation: update tunable options in block/cfq-iosched.txt Documentation: update missing index files in block/00-INDEX block: move down direct IO plugging block: remove plugging at buffered write time block: disable discard request merge temporarily bio: Fix potential memory leak in bio_find_or_create_slab() block: Don't use static to define "void *p" in show_partition_start() block: Add blk_bio_map_sg() helper block: Introduce __blk_segment_map_sg() helper fs/block-dev.c:fix performance regression in O_DIRECT writes to md block devices block: split discard into aligned requests block: reorganize rounding of max_discard_sectors
