bpf: sockmap, free memory on sock close with cork data
If a socket with pending cork data is closed we do not return the
memory to the socket until the garbage collector free's the psock
structure. The garbage collector though can run after the sock has
completed its close operation. If this ordering happens the sock code
will through a WARN_ON because there is still outstanding memory
accounted to the sock.
To resolve this ensure we return memory to the sock when a socket
is closed.

Pull sparc updates from David Miller: 1) Add support for ADI (Application Data Integrity) found in more recent sparc64 cpus. Essentially this is keyed based access to virtual memory, and if the key encoded in the virual address is wrong you get a trap. The mm changes were reviewed by Andrew Morton and others. Work by Khalid Aziz. 2) Validate DAX completion index range properly, from Rob Gardner. 3) Add proper Kconfig deps for DAX driver. From Guenter Roeck. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc-next: sparc64: Make atomic_xchg() an inline function rather than a macro. sparc64: Properly range check DAX completion index sparc: Make auxiliary vectors for ADI available on 32-bit as well sparc64: Oracle DAX driver depends on SPARC64 sparc64: Update signal delivery to use new helper functions sparc64: Add support for ADI (Application Data Integrity) mm: Allow arch code to override copy_highpage() mm: Clear arch specific VM flags on protection change mm: Add address parameter to arch_validate_prot() sparc64: Add auxiliary vectors to report platform ADI properties sparc64: Add handler for "Memory Corruption Detected" trap sparc64: Add HV fault type handlers for ADI related faults sparc64: Add support for ADI register fields, ASIs and traps mm, swap: Add infrastructure for saving page metadata on swap signals, sparc: Add signal codes for ADI violations |

Pull networking updates from David Miller: 1) Support offloading wireless authentication to userspace via NL80211_CMD_EXTERNAL_AUTH, from Srinivas Dasari. 2) A lot of work on network namespace setup/teardown from Kirill Tkhai. Setup and cleanup of namespaces now all run asynchronously and thus performance is significantly increased. 3) Add rx/tx timestamping support to mv88e6xxx driver, from Brandon Streiff. 4) Support zerocopy on RDS sockets, from Sowmini Varadhan. 5) Use denser instruction encoding in x86 eBPF JIT, from Daniel Borkmann. 6) Support hw offload of vlan filtering in mvpp2 dreiver, from Maxime Chevallier. 7) Support grafting of child qdiscs in mlxsw driver, from Nogah Frankel. 8) Add packet forwarding tests to selftests, from Ido Schimmel. 9) Deal with sub-optimal GSO packets better in BBR congestion control, from Eric Dumazet. 10) Support 5-tuple hashing in ipv6 multipath routing, from David Ahern. 11) Add path MTU tests to selftests, from Stefano Brivio. 12) Various bits of IPSEC offloading support for mlx5, from Aviad Yehezkel, Yossi Kuperman, and Saeed Mahameed. 13) Support RSS spreading on ntuple filters in SFC driver, from Edward Cree. 14) Lots of sockmap work from John Fastabend. Applications can use eBPF to filter sendmsg and sendpage operations. 15) In-kernel receive TLS support, from Dave Watson. 16) Add XDP support to ixgbevf, this is significant because it should allow optimized XDP usage in various cloud environments. From Tony Nguyen. 17) Add new Intel E800 series "ice" ethernet driver, from Anirudh Venkataramanan et al. 18) IP fragmentation match offload support in nfp driver, from Pieter Jansen van Vuuren. 19) Support XDP redirect in i40e driver, from Björn Töpel. 20) Add BPF_RAW_TRACEPOINT program type for accessing the arguments of tracepoints in their raw form, from Alexei Starovoitov. 21) Lots of striding RQ improvements to mlx5 driver with many performance improvements, from Tariq Toukan. 22) Use rhashtable for inet frag reassembly, from Eric Dumazet. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1678 commits) net: mvneta: improve suspend/resume net: mvneta: split rxq/txq init and txq deinit into SW and HW parts ipv6: frags: fix /proc/sys/net/ipv6/ip6frag_low_thresh net: bgmac: Fix endian access in bgmac_dma_tx_ring_free() net: bgmac: Correctly annotate register space route: check sysctl_fib_multipath_use_neigh earlier than hash fix typo in command value in drivers/net/phy/mdio-bitbang. sky2: Increase D3 delay to sky2 stops working after suspend net/mlx5e: Set EQE based as default TX interrupt moderation mode ibmvnic: Disable irqs before exiting reset from closed state net: sched: do not emit messages while holding spinlock vlan: also check phy_driver ts_info for vlan's real device Bluetooth: Mark expected switch fall-throughs Bluetooth: Set HCI_QUIRK_SIMULTANEOUS_DISCOVERY for BTUSB_QCA_ROME Bluetooth: btrsi: remove unused including <linux/version.h> Bluetooth: hci_bcm: Remove DMI quirk for the MINIX Z83-4 sh_eth: kill useless check in __sh_eth_get_regs() sh_eth: add sh_eth_cpu_data::no_xdfar flag ipv6: factorize sk_wmem_alloc updates done by __ip6_append_data() ipv4: factorize sk_wmem_alloc updates done by __ip_append_data() ... |

Mostly small changes, as usual.
This does add an IPMI BMC server-side driver, to allow a Linux system to act as an IPMI controller. That's the biggest change, but it is just a new driver that is fairly narrow in use. The other largish change is removing ACPI SPMI probe support, which should have never really been there in the beginning. -corey -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJaw8XOAAoJEGHzjJCRm/+BeoQQAIBokkgHSAl6y8jlmmTmu9fV gXl0GT97yAMyuTUaTvkWLdWm8GWCrSSUTAqjbcTzMWya87KRODsUg9eTO58fFw8m ODbD7ruTGmBQggJEqDaS5NHAiU22ce2aDn5I0WjJkH8vaJ3nQSa6nEgBOzXDMC1A OmaVQE6BnEAIA+nmlzbUgcuduB3iv7gTua2gy7MQSG/5jBPIAOQtpsgHtCZMA+Dt bk9LqDpOa6dZry7eIn5/u62YRVLX+iVO/DoxCgZyOxVfgnV/ykKT3PvWO9vviBQV QXXLAzLO3niDQ/ZwwpqrUWjR7oGWDKe4ntMATfnxCP7LQNrSF7LnAxz8oCcwuBxq ELrwME8LEQmMYGFg3SYcLA0k1teTP2UVWURUH6zBTft2xzo8bJN0JU7J52tTL4xa yC7JgTVeq8uQB8gkYKf43LGHlXlaxFQsnRKeCJ2JG+1yD+sOmxbZshfiLroMZ5DM nPKOuMdoqPCd7JVUMs/c0IgcDHd6vtkiDRA0jh38JdIdp9B/i+dFYs61bSzrkBD9 tXUua56QTVl5WEWy2lGX+ZH/JUJbQnTxjiaW99Q9Soml6qXqIVjR5ZvLtls0PeW0 ZytaQEGuV8758YEmOGk/1pUys/oC37mDlyjTpONGYzvAyzJqU258/YU9eJMkcQ/G FFEEkWILLuGgtFnyxwN/ =p993 -----END PGP SIGNATURE----- Merge tag 'for-linus-4.17' of git://github.com/cminyard/linux-ipmi Pull IPMI updates from Corey Minyard: "Mostly small changes, as usual.

Merge branch 'syscalls-next' of git://git.kernel.org/pub/scm/linux/kernel/git/brodo/linux
Pull removal of in-kernel calls to syscalls from Dominik Brodowski: "System calls are interaction points between userspace and the kernel. Therefore, system call functions such as sys_xyzzy() or compat_sys_xyzzy() should only be called from userspace via the syscall table, but not from elsewhere in the kernel. At least on 64-bit x86, it will likely be a hard requirement from v4.17 onwards to not call system call functions in the kernel: It is better to use use a different calling convention for system calls there, where struct pt_regs is decoded on-the-fly in a syscall wrapper which then hands processing over to the actual syscall function. This means that only those parameters which are actually needed for a specific syscall are passed on during syscall entry, instead of filling in six CPU registers with random user space content all the time (which may cause serious trouble down the call chain). Those x86-specific patches will be pushed through the x86 tree in the near future. Moreover, rules on how data may be accessed may differ between kernel data and user data. This is another reason why calling sys_xyzzy() is generally a bad idea, and -- at most -- acceptable in arch-specific code. This patchset removes all in-kernel calls to syscall functions in the kernel with the exception of arch/. On top of this, it cleans up the three places where many syscalls are referenced or prototyped, namely kernel/sys_ni.c, include/linux/syscalls.h and include/linux/compat.h" * 'syscalls-next' of git://git.kernel.org/pub/scm/linux/kernel/git/brodo/linux: (109 commits) bpf: whitelist all syscalls for error injection kernel/sys_ni: remove {sys_,sys_compat} from cond_syscall definitions kernel/sys_ni: sort cond_syscall() entries syscalls/x86: auto-create compat_sys_*() prototypes syscalls: sort syscall prototypes in include/linux/compat.h net: remove compat_sys_*() prototypes from net/compat.h syscalls: sort syscall prototypes in include/linux/syscalls.h kexec: move sys_kexec_load() prototype to syscalls.h x86/sigreturn: use SYSCALL_DEFINE0 x86: fix sys_sigreturn() return type to be long, not unsigned long x86/ioport: add ksys_ioperm() helper; remove in-kernel calls to sys_ioperm() mm: add ksys_readahead() helper; remove in-kernel calls to sys_readahead() mm: add ksys_mmap_pgoff() helper; remove in-kernel calls to sys_mmap_pgoff() mm: add ksys_fadvise64_64() helper; remove in-kernel call to sys_fadvise64_64() fs: add ksys_fallocate() wrapper; remove in-kernel calls to sys_fallocate() fs: add ksys_p{read,write}64() helpers; remove in-kernel calls to syscalls fs: add ksys_truncate() wrapper; remove in-kernel calls to sys_truncate() fs: add ksys_sync_file_range helper(); remove in-kernel calls to syscall kernel: add ksys_setsid() helper; remove in-kernel call to sys_setsid() kernel: add ksys_unshare() helper; remove in-kernel calls to sys_unshare() ... |

arch: remove obsolete architecture ports
This removes the entire architecture code for blackfin, cris, frv, m32r, metag, mn10300, score, and tile, including the associated device drivers. I have been working with the (former) maintainers for each one to ensure that my interpretation was right and the code is definitely unused in mainline kernels. Many had fond memories of working on the respective ports to start with and getting them included in upstream, but also saw no point in keeping the port alive without any users. In the end, it seems that while the eight architectures are extremely different, they all suffered the same fate: There was one company in charge of an SoC line, a CPU microarchitecture and a software ecosystem, which was more costly than licensing newer off-the-shelf CPU cores from a third party (typically ARM, MIPS, or RISC-V). It seems that all the SoC product lines are still around, but have not used the custom CPU architectures for several years at this point. In contrast, CPU instruction sets that remain popular and have actively maintained kernel ports tend to all be used across multiple licensees. The removal came out of a discussion that is now documented at https://lwn.net/Articles/748074/. Unlike the original plans, I'm not marking any ports as deprecated but remove them all at once after I made sure that they are all unused. Some architectures (notably tile, mn10300, and blackfin) are still being shipped in products with old kernels, but those products will never be updated to newer kernel releases. After this series, we still have a few architectures without mainline gcc support: - unicore32 and hexagon both have very outdated gcc releases, but the maintainers promised to work on providing something newer. At least in case of hexagon, this will only be llvm, not gcc. - openrisc, risc-v and nds32 are still in the process of finishing their support or getting it added to mainline gcc in the first place. They all have patched gcc-7.3 ports that work to some degree, but complete upstream support won't happen before gcc-8.1. Csky posted their first kernel patch set last week, their situation will be similar. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJawdL2AAoJEGCrR//JCVInuH0P/RJAZh1nTD+TR34ZhJq2TBoo PgygwDU7Z2+tQVU+EZ453Gywz9/NMRFk1RWAZqrLix4ZtyIMvC6A1qfT2yH1Y7Fb Qh6tccQeLe4ezq5u4S/46R/fQXu3Txr92yVwzJJUuPyU0arF9rv5MmI8e6p7L1en yb74kSEaCe+/eMlsEj1Cc1dgthDNXGKIURHkRsILoweysCpesjiTg4qDcL+yTibV FP2wjVbniKESMKS6qL71tiT5sexvLsLwMNcGiHPj94qCIQuI7DLhLdBVsL5Su6gI sbtgv0dsq4auRYAbQdMaH1hFvu6WptsuttIbOMnz2Yegi2z28H8uVXkbk2WVLbqG ZESUwutGh8MzOL2RJ4jyyQq5sfo++CRGlfKjr6ImZRv03dv0pe/W85062cK5cKNs cgDDJjGRorOXW7dyU6jG2gRqODOQBObIv3w5efdq5OgzOWlbI4EC+Y5u1Z0JF/76 pSwtGXA6YhwC+9LLAlnVTHG+yOwuLmAICgoKcTbzTVDKA2YQZG/cYuQfI5S1wD8e X6urPx3Md2GCwLXQ9mzKBzKZUpu/Tuhx0NvwF4qVxy6x1PELjn68zuP7abDHr46r 57/09ooVN+iXXnEGMtQVS/OPvYHSa2NgTSZz6Y86lCRbZmUOOlK31RDNlMvYNA+s 3iIVHovno/JuJnTOE8LY =fQ8z -----END PGP SIGNATURE----- Merge tag 'arch-removal' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic Pul removal of obsolete architecture ports from Arnd Bergmann: "This removes the entire architecture code for blackfin, cris, frv, m32r, metag, mn10300, score, and tile, including the associated device drivers.

bpf: whitelist all syscalls for error injection
Error injection is a useful mechanism to fail arbitrary kernel functions. However, it is often hard to guarantee an error propagates appropriately to user space programs. By injecting into syscalls, we can return arbitrary values to user space directly; this increases flexibility and robustness in testing, allowing us to test user space error paths effectively. The following script, for example, fails calls to sys_open() from a given pid: from bcc import BPF from sys import argv pid = argv[1] prog = r""" int kprobe__SyS_open(struct pt_regs *ctx, const char *pathname, int flags) { u32 pid = bpf_get_current_pid_tgid(); if (pid == %s) bpf_override_return(ctx, -ENOMEM); return 0; } """ % pid b = BPF(text=prog) while 1: b.perf_buffer_poll() This patch whitelists all syscalls defined with SYSCALL_DEFINE and COMPAT_SYSCALL_DEFINE for error injection. These changes are not intended to be considered stable, and would normally be configured off.

syscalls/x86: auto-create compat_sys_*() prototypes
compat_sys_*() functions are no longer called from within the kernel on x86 except from the system call table. Linking the system call does not require compat_sys_*() function prototypes at least on x86. Therefore, generate compat_sys_*() prototypes on-the-fly within the COMPAT_SYSCALL_DEFINEx() macro, and remove x86-specific prototypes from various header files.
