* mm, oom: base root bonus on current usageDavid Rientjes2014-02-131-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 778c14affaf94a9e4953179d3e13a544ccce7707 upstream. A 3% of system memory bonus is sometimes too excessive in comparison to other processes. With commit a63d83f427fb ("oom: badness heuristic rewrite"), the OOM killer tries to avoid killing privileged tasks by subtracting 3% of overall memory (system or cgroup) from their per-task consumption. But as a result, all root tasks that consume less than 3% of overall memory are considered equal, and so it only takes 33+ privileged tasks pushing the system out of memory for the OOM killer to do something stupid and kill dhclient or other root-owned processes. For example, on a 32G machine it can't tell the difference between the 1M agetty and the 10G fork bomb member. The changelog describes this 3% boost as the equivalent to the global overcommit limit being 3% higher for privileged tasks, but this is not the same as discounting 3% of overall memory from _every privileged task individually_ during OOM selection. Replace the 3% of system memory bonus with a 3% of current memory usage bonus. By giving root tasks a bonus that is proportional to their actual size, they remain comparable even when relatively small. In the example above, the OOM killer will discount the 1M agetty's 256 badness points down to 179, and the 10G fork bomb's 262144 points down to 183500 points and make the right choice, instead of discounting both to 0 and killing agetty because it's first in the task list.

* ata: sata_mv: introduce compatible string "marvell, armada-370-sata"Simon Guinot2014-02-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | commit b1f5c73bd5a4752efb7d7af019034044b08aafe9 upstream. The sata_mv driver supports the SATA IP found in several Marvell SoCs. As some new SATA registers have been introduced with the Armada 370/XP SoCs, a way to identify them is needed. This patch introduces a new compatible string for the SATA IP found in Armada 370/XP SoCs.

* packet: fix send path when running with proto == 0Daniel Borkmann2014-01-151-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit 66e56cd46b93ef407c60adcac62cf33b06119d50 ] Commit e40526cb20b5 introduced a cached dev pointer, that gets hooked into register_prot_hook(), __unregister_prot_hook() to update the device used for the send path. We need to fix this up, as otherwise this will not work with sockets created with protocol = 0, plus with sll_protocol = 0 passed via sockaddr_ll when doing the bind. So instead, assign the pointer directly. The compiler can inline these helper functions automagically. While at it, also assume the cached dev fast-path as likely(), and document this variant of socket creation as it seems it is not widely used (seems not even the author of TX_RING was aware of that in his reference example [1]). Tested with reproducer from e40526cb20b5.

* libata: disable a disk via libata.force paramsRobin H. Johnson2014-01-091-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | commit b8bd6dc36186fe99afa7b73e9e2d9a98ad5c4865 upstream. A user on StackExchange had a failing SSD that's soldered directly onto the motherboard of his system. The BIOS does not give any option to disable it at all, so he can't just hide it from the OS via the BIOS. The old IDE layer had hdX=noprobe override for situations like this, but that was never ported to the libata layer. This patch implements a disable flag for libata.force.

* libata: Add atapi_dmadir force flagVincent Pelletier2014-01-091-0/+2
| | | | | | | | | | | | | | | | | | | | | commit 966fbe193f47c68e70a80ec9991098e88e7959cb upstream. Some device require DMADIR to be enabled, but are not detected as such by atapi_id_dmadir. One such example is "Asus Serillel 2" SATA-host-to-PATA-device bridge: the bridge itself requires DMADIR, even if the bridged device does not. As atapi_dmadir module parameter can cause problems with some devices (as per Tejun Heo's memory), enabling it globally may not be possible depending on the hardware. This patch adds atapi_dmadir in the form of a "force" horkage value, allowing global, per-bus and per-device control.

* tcp: tsq: restore minimal amount of queueingEric Dumazet2013-12-081-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit 98e09386c0ef4dfd48af7ba60ff908f0d525cdee ] After commit c9eeec26e32e ("tcp: TSQ can use a dynamic limit"), several users reported throughput regressions, notably on mvneta and wifi adapters. 802.11 AMPDU requires a fair amount of queueing to be effective. This patch partially reverts the change done in tcp_write_xmit() so that the minimal amount is sysctl_tcp_limit_output_bytes. It also remove the use of this sysctl while building skb stored in write queue, as TSO autosizing does the right thing anyway. Users with well behaving NICS and correct qdisc (like sch_fq), can then lower the default sysctl_tcp_limit_output_bytes value from 128KB to 8KB. This new usage of sysctl_tcp_limit_output_bytes permits each driver authors to check how their driver performs when/if the value is set to a minimum of 4KB. Normally, line rate for a single TCP flow should be possible, but some drivers rely on timers to perform TX completion and too long TX completion delays prevent reaching full throughput.

* vsprintf: check real user/group id for %pKRyan Mallon2013-12-041-7/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 312b4e226951f707e120b95b118cbc14f3d162b2 upstream. Some setuid binaries will allow reading of files which have read permission by the real user id. This is problematic with files which use %pK because the file access permission is checked at open() time, but the kptr_restrict setting is checked at read() time. If a setuid binary opens a %pK file as an unprivileged user, and then elevates permissions before reading the file, then kernel pointer values may be leaked. This happens for example with the setuid pppd application on Ubuntu 12.04: $ head -1 /proc/kallsyms 00000000 T startup_32 $ pppd file /proc/kallsyms pppd: In file /proc/kallsyms: unrecognized option 'c1000000' This will only leak the pointer value from the first line, but other setuid binaries may leak more information. Fix this by adding a check that in addition to the current process having CAP_SYSLOG, that effective user and group ids are equal to the real ids. If a setuid binary reads the contents of a file which uses %pK then the pointer values will be printed as NULL if the real user is unprivileged. Update the sysctl documentation to reflect the changes, and also correct the documentation to state the kptr_restrict=0 is the default. This is a only temporary solution to the issue. The correct solution is to do the permission check at open() time on files, and to replace %pK with a function which checks the open() time permission. %pK uses in printk should be removed since no sane permission check can be done, and instead protected by using dmesg_restrict.

* tcp: TSO packets automatic sizingEric Dumazet2013-11-041-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commits 6d36824e730f247b602c90e8715a792003e3c5a7, 02cf4ebd82ff0ac7254b88e466820a290ed8289a, and parts of 7eec4174ff29cd42f2acfae8112f51c228545d40 ] After hearing many people over past years complaining against TSO being bursty or even buggy, we are proud to present automatic sizing of TSO packets. One part of the problem is that tcp_tso_should_defer() uses an heuristic relying on upcoming ACKS instead of a timer, but more generally, having big TSO packets makes little sense for low rates, as it tends to create micro bursts on the network, and general consensus is to reduce the buffering amount. This patch introduces a per socket sk_pacing_rate, that approximates the current sending rate, and allows us to size the TSO packets so that we try to send one packet every ms. This field could be set by other transports. Patch has no impact for high speed flows, where having large TSO packets makes sense to reach line rate. For other flows, this helps better packet scheduling and ACK clocking. This patch increases performance of TCP flows in lossy environments. A new sysctl (tcp_min_tso_segs) is added, to specify the minimal size of a TSO packet (default being 2). A follow-up patch will provide a new packet scheduler (FQ), using sk_pacing_rate as an input to perform optional per flow pacing. This explains why we chose to set sk_pacing_rate to twice the current rate, allowing 'slow start' ramp up. sk_pacing_rate = 2 * cwnd * mss / srtt v2: Neal Cardwell reported a suspect deferring of last two segments on initial write of 10 MSS, I had to change tcp_tso_should_defer() to take into account tp->xmit_size_goal_segs Signed-off-by: Eric Dumazet <edumazet@google.com> Cc: Neal Cardwell <ncardwell@google.com> Cc: Yuchung Cheng <ycheng@google.com> Cc: Van Jacobson <vanj@google.com> Cc: Tom Herbert <therbert@google.com> Acked-by: Yuchung Cheng <ycheng@google.com> Acked-by: Neal Cardwell <ncardwell@google.com> Signed-off-by: David S.

In this case there is an ipv4 route attached, so it gets stomped on. Reported by Dave Jones and Hannes Frederic Sowa, fixed by Eric Dumazet. 2) AF_KEY notifications leak some kernel memory to userspace, fix from Mathias Krause. 3) DLCI calls __dev_get_by_name() without proper locking, and dlci_del doesn't validate that the device being deleted is actually a DLCI one. Fixes from Li Zefan. 4) Length check on bluetooth l2cap information responses is wrong, each response type has a different lenth, so we should make sure it's in a given range rather than enforce one single valid length. From Jaganath Kanakkassery. 5) Receive FIFO overflow is really easy to trigger in stress scenerios in the sh_eth driver, but the event isn't being handled properly at all. Specifically, the mask of error interrupts doesn't include the event so we never clear it, resulting in the driver becomming wedged processing an interrupt that never gets cleared. Fix from Sergei Shtylyov. 6) qlcnic sleeps while holding a spinlock, use mdelay() instead of msleep(). From Shahed Shaikh. 7) Missing curly braces causes SIP netfilter NAT module to always drop packets. Fix from Balazs Peter Odor. 8) ipt_ULOG in netfilter passes the wrong value to timer setup, causing the timer to dereference crap when it fires. Fix from Gao Feng. 9) Missing RCU protection around txq->axq_acq traversal in ath_txq_schedule(). Fix from Felix Fietkau. 10) Idle state transition test in ath9k_htc_config() is reversed, fix from Sujith Manoharan. 11) IPV6 forwarding handles unicast Router Alert packets incorrectly. It tests the wrong option state. Previously opt->ra being non-zero indicated a router alert marking in the SKB, but now it's indicated by a bit in opt->flags. Fix from YOSHIFUJI Hideaki. 12) SKB leak in GRE tunnel GSO handling, from Eric Dumazet. 13) get_user_pages_fast() error handling in TUN and MACVTAP use the same local variable for the base index and the loop iterator for page traversal, oops! Fix from Michael S Tsirkin. 14) ipv6_get_lladdr() can fail, and we must therefore check it's return value in inet6_set_iftoken(). For from Hannes Frederic Sowa. 15) If you change an interface name and meanwhile can sneak in something that looks up the name (like SO_BINDTODEVICE or SIOCGIFNAME) we can deadlock with CONFIG_PREEMPT=n. Fix this by providing a helper function that properly uses raw_seqcount_begin(). From Nicolas Schichan. 16) Chain noise calibration test is inverted in iwlwifi, fix from Nikolay Martynov. 17) Properly set TX iwlwifi descriptor flags for back requests. Fix from Emmanuel Grumbach. 18) We can't assume skb_transport_header() is set in xt_TCPOPTSTRAP module, fix from Pablo Neira Ayuso. 19) Some crummy APs don't provide the proper High Throughput info in association response frames. Add a workaround by assume we'll use whatever is in the beacon/probe. Fix from Johannes Berg. 20) mac80211 call to rate_idx_match_mask() swaps two arguments (mask and channel width). Fix from Simon Wunderlich. 21) xt_TCPMSS (like xt_TCPOPTSTRAP) must not try to handle fragmented frames.

It's possible that the stack has moved back up after the tbegin. The obvious case here is when the tbegin is called inside a function that returns before a tend. In this case, the stack is part of the checkpointed transactional memory state. If we write over this non transactionally or in suspend, we are in trouble because if we get a tm abort, the program counter and stack pointer will be back at the tbegin but our in memory stack won't be valid anymore. To avoid this, when taking a signal in an active transaction, we need to use the stack pointer from the checkpointed state, rather than the speculated state. This ensures that the signal context (written tm suspended) will be written below the stack required for the rollback. The transaction is aborted becuase of the treclaim, so any memory written between the tbegin and the signal will be rolled back anyway. For signals taken in non-TM or suspended mode, we use the normal/non-checkpointed stack pointer.

We need to abort these transactions and send them back to userspace for the hardware to rollback. We can service these if the user transaction is in suspend mode, since the kernel will operate in the same suspend context. This adds a check to all alignment faults and to specific instruction emulations (only string instructions for now). If the user process is in an active (non-suspended) transaction, we abort the transaction go back to userspace allowing the HW to roll back the transaction and tell the user of the failure. This also adds new tm abort cause codes to report the reason of the persistent error to the user.

This is useful in cases where a bootloader exists and has set up the display hardware, but a Linux driver doesn't yet exist for the display hardware. Examples use-cases include: * The built-in LCD panels on the Samsung ARM chromebook, and Tegra devices, and likely many other ARM or embedded systems. These cannot yet be supported using a full graphics driver, since the panel control should be provided by the CDF (Common Display Framework), which has been stuck in design/review for quite some time. One could support these panels using custom SoC-specific code, but there is a desire to use common infra-structure rather than having each SoC vendor invent their own code, hence the desire to wait for CDF. * Hardware for which a full graphics driver is not yet available, and the path to obtain one upstream isn't yet clear. For example, the Raspberry Pi. * Any hardware in early stages of upstreaming, before a full graphics driver has been tackled. This driver can provide a graphical boot console (even full X support) much earlier in the upstreaming process, thus making new SoC or board support more generally useful earlier.
