2016-06-10packet: compat support for sock_fprogWillem de Bruijn1-0/+1
Socket option PACKET_FANOUT_DATA takes a struct sock_fprog as argument if PACKET_FANOUT has mode PACKET_FANOUT_CBPF. This structure contains a pointer into user memory. If userland is 32-bit and kernel is 64-bit the two disagree about the layout of struct sock_fprog. Add compat setsockopt support to convert a 32-bit compat_sock_fprog to a 64-bit sock_fprog. This is analogous to compat_sock_fprog support for SO_REUSEPORT added in commit 1957598840f4 ("soreuseport: add compat case for setsockopt SO_ATTACH_REUSEPORT_CBPF").

In RoCE, the RDMA-CM needs the node guid to establish connection between nodes. Today, the node guid exposed to mlx5 Ethernet VFs is zero, therefore RDMA-CM on the VF is broken.

For example IB_DEVICE_SG_GAPS_REG was falsely read by the iser driver causing it to use a non-existing capability. This happened because signed int becomes sign extended when converted it to u64.

2016-06-06ipvs: update real-server binding of outgoing connections in SIP-peMarco Angaroni1-1/+1
Previous patch that introduced handling of outgoing packets in SIP persistent-engine did not call ip_vs_check_template() in case packet was matching a connection template. Assumption was that real-server was healthy, since it was sending a packet just in that moment. There are however real-server fault conditions requiring that association between call-id and real-server (represented by connection template) gets updated. Here is an example of the sequence of events: 1) RS1 is a back2back user agent that handled call-id1 and call-id2 2) RS1 is down and was marked as unavailable 3) new message from outside comes to IPVS with call-id1 4) IPVS reschedules the message to RS2, which becomes new call handler 5) RS2 forwards the message outside, translating call-id1 to call-id2 6) inside pe->conn_out() IPVS matches call-id2 with existing template 7) IPVS does not change association call-id2 <-> RS1 8) new message comes from client with call-id2 9) IPVS reschedules the message to a real-server potentially different from RS2, which is now the correct destination This patch introduces ip_vs_check_template() call in the handling of outgoing packets for SIP-pe. And also introduces a second optional argument for ip_vs_check_template() that allows to check if dest associated to a connection template is the same dest that was identified as the source of the packet. This is to change the real-server bound to a particular call-id independently from its availability status: the idea is that it's more reliable, for in->out direction (where internal network can be considered trusted), to always associate a call-id with the last real-server that used it in one of its messages. Think about above sequence of events where, just after step 5, RS1 returns instead to be available. Comparison of dests is done by simply comparing pointers to struct ip_vs_dest; there should be no cases where struct ip_vs_dest keeps its memory address, but represent a different real-server in terms of ip-address / port.

2016-06-05devpts: Make each mount of devpts an independent filesystem.Eric W. Biederman2-5/+6
The /dev/ptmx device node is changed to lookup the directory entry "pts" in the same directory as the /dev/ptmx device node was opened in. If there is a "pts" entry and that entry is a devpts filesystem /dev/ptmx uses that filesystem. Otherwise the open of /dev/ptmx fails. The DEVPTS_MULTIPLE_INSTANCES configuration option is removed, so that userspace can now safely depend on each mount of devpts creating a new instance of the filesystem. Each mount of devpts is now a separate and equal filesystem. Reserved ttys are now available to all instances of devpts where the mounter is in the initial mount namespace. A new vfs helper path_pts is introduced that finds a directory entry named "pts" in the directory of the passed in path, and changes the passed in path to point to it. The helper path_pts uses a function path_parent_directory that was factored out of follow_dotdot. In the implementation of devpts: - devpts_mnt is killed as it is no longer meaningful if all mounts of devpts are equal. - pts_sb_from_inode is replaced by just inode->i_sb as all cached inodes in the tty layer are now from the devpts filesystem. - devpts_add_ref is rolled into the new function devpts_ptmx. And the unnecessary inode hold is removed. - devpts_del_ref is renamed devpts_release and reduced to just a deacrivate_super. - The newinstance mount option continues to be accepted but is now ignored. In devpts_fs.h definitions for when !CONFIG_UNIX98_PTYS are removed as they are never used. Documentation/filesystems/devices.txt is updated to describe the current situation. This has been verified to work properly on openwrt-15.05, centos5, centos6, centos7, debian-6.0.2, debian-7.9, debian-8.2, ubuntu-14.04.3, ubuntu-15.10, fedora23, magia-5, mint-17.3, opensuse-42.1, slackware-14.1, gentoo-20151225 (13.0?), archlinux-2015-12-01. With the caveat that on centos6 and on slackware-14.1 that there wind up being two instances of the devpts filesystem mounted on /dev/pts, the lower copy does not end up getting used.

2016-06-03cpuidle: Do not access cpuidle_devices when !CONFIG_CPU_IDLECatalin Marinas1-0/+3
The cpuidle_devices per-CPU variable is only defined when CPU_IDLE is enabled. Commit c8cc7d4de7a4 ("sched/idle: Reorganize the idle loop") removed the #ifdef CONFIG_CPU_IDLE around cpuidle_idle_call() with the compiler optimising away __this_cpu_read(cpuidle_devices). However, with CONFIG_UBSAN && !CONFIG_CPU_IDLE, this optimisation no longer happens and the kernel fails to link since cpuidle_devices is not defined. This patch introduces an accessor function for the current CPU cpuidle device (returning NULL when !CONFIG_CPU_IDLE) and uses it in cpuidle_idle_call().

2016-06-01time: Make settimeofday error checking work againJohn Stultz1-0/+3
In commit 86d3473224b0 some of the checking for a valid timeval was subtley changed which caused -EINVAL to be returned whenever the timeval was null. However, it is possible to set the timezone data while specifying a NULL timeval, which is usually done to handle systems where the RTC keeps local time instead of UTC. Thus the patch causes such systems to have the time incorrectly set. This patch addresses the issue by handling the error conditionals in the same way as was done previously.

Now we cannot distinguish that one sk is a udp or sctp style when we use ss to dump sctp_info. it's necessary to dump it as well. For sctp_diag, ss support is not officially available, thus there are no official users of this yet, so we can add this field in the middle of sctp_info without breaking user API. v1->v2: - move 'sctpi_s_type' field to the end of struct sctp_info, so that it won't cause incompatibility with applications already built. - add __reserved3 in sctp_info to make sure sctp_info is 8-byte alignment.

2016-05-29Merge branch 'hash' of git://ftp.sciencehorizons.net/linuxLinus Torvalds4-110/+141
Pull string hash improvements from George Spelvin: "This series does several related things: - Makes the dcache hash (fs/namei.c) useful for general kernel use. (Thanks to Bruce for noticing the zero-length corner case) - Converts the string hashes in <linux/sunrpc/svcauth.h> to use the above. - Avoids 64-bit multiplies in hash_64() on 32-bit platforms. Two 32-bit multiplies will do well enough. - Rids the world of the bad hash multipliers in hash_32. This finishes the job started in commit 689de1d6ca95 ("Minimal fix-up of bad hashing behavior of hash_64()") The vast majority of Linux architectures have hardware support for 32x32-bit multiply and so derive no benefit from "simplified" multipliers. The few processors that do not (68000, h8/300 and some models of Microblaze) have arch-specific implementations added. Those patches are last in the series. - Overhauls the dcache hash mixing. The patch in commit 0fed3ac866ea ("namei: Improve hash mixing if CONFIG_DCACHE_WORD_ACCESS") was an off-the-cuff suggestion. Replaced with a much more careful design that's simultaneously faster and better. (My own invention, as there was noting suitable in the literature I could find. Comments welcome!) - Modify the hash_name() loop to skip the initial HASH_MIX(). This would let us salt the hash if we ever wanted to. - Sort out partial_name_hash(). The hash function is declared as using a long state, even though it's truncated to 32 bits at the end and the extra internal state contributes nothing to the result. And some callers do odd things: - fs/hfs/string.c only allocates 32 bits of state - fs/hfsplus/unicode.c uses it to hash 16-bit unicode symbols not bytes - Modify bytemask_from_count to handle inputs of 1..sizeof(long) rather than 0..sizeof(long)-1. This would simplify users other than full_name_hash" Special thanks to Bruce Fields for testing and finding bugs in v1. (I learned some humbling lessons about "obviously correct" code.) On the arch-specific front, the m68k assembly has been tested in a standalone test harness, I've been in contact with the Microblaze maintainers who mostly don't care, as the hardware multiplier is never omitted in real-world applications, and I haven't heard anything from the H8/300 world" * 'hash' of git://ftp.sciencehorizons.net/linux: h8300: Add <asm/hash.h> microblaze: Add <asm/hash.h> m68k: Add <asm/hash.h> <linux/hash.h>: Add support for architecture-specific functions fs/namei.c: Improve dcache hash function Eliminate bad hash multipliers from hash_32() and hash_64() Change hash_64() return value to 32 bits <linux/sunrpc/svcauth.h>: Define hash_str() in terms of hashlen_string() fs/namei.c: Add hashlen_string() function Pull out string hash to <linux/stringhash.h>
2016-05-28<linux/hash.h>: Add support for architecture-specific functionsGeorge Spelvin1-3/+24
This is just the infrastructure; there are no users yet. This is modelled on CONFIG_ARCH_RANDOM; a CONFIG_ symbol declares the existence of <asm/hash.h>. That file may define its own versions of various functions, and define HAVE_* symbols (no CONFIG_ prefix!) to suppress the generic ones. Included is a self-test (in lib/test_hash.c) that verifies the basics. It is NOT in general required that the arch-specific functions compute the same thing as the generic, but if a HAVE_* symbol is defined with the value 1, then equality is tested.

2016-05-28Eliminate bad hash multipliers from hash_32() and hash_64()George Spelvin1-53/+34
The "simplified" prime multipliers made very bad hash functions, so get rid of them. This completes the work of 689de1d6ca. To avoid the inefficiency which was the motivation for the "simplified" multipliers, hash_64() on 32-bit systems is changed to use a different algorithm. It makes two calls to hash_32() instead. drivers/media/usb/dvb-usb-v2/af9015.c uses the old GOLDEN_RATIO_PRIME_32 for some horrible reason, so it inherits a copy of the old definition.

2016-05-28Change hash_64() return value to 32 bitsGeorge Spelvin1-3/+3
That's all that's ever asked for, and it makes the return type of hash_long() consistent. It also allows (upcoming patch) an optimized implementation of hash_64 on 32-bit machines. I tried adding a BUILD_BUG_ON to ensure the number of bits requested was never more than 32 (most callers use a compile-time constant), but adding <linux/bug.h> to <linux/hash.h> breaks the tools/perf compiler unless tools/perf/MANIFEST is updated, and understanding that code base well enough to update it is too much trouble. I did the rest of an allyesconfig build with such a check, and nothing tripped. Signed-off-by: George Spelvin <linux@sciencehorizons.net>
