virtchnl: Add virtchl structures to support queue channels
This patch defines new structs in support of the virtchannel message that the VF sends to the PF to create a queue channel specified by the user via tc tool.

net: Allow pernet_operations to be executed in parallel
This adds new pernet_operations::async flag to indicate operations, which ->init(), ->exit() and ->exit_batch() methods are allowed to be executed in parallel with the methods of any other pernet_operations. When there are only asynchronous pernet_operations in the system, net_mutex won't be taken for a net construction and destruction. Also, remove BUG_ON(mutex_is_locked()) from net_assign_generic() without replacing with the equivalent net_sem check, as there is one more lockdep assert below. v3: Add comment near net_mutex.

net: Introduce net_sem for protection of pernet_list
Currently, the mutex is mostly used to protect pernet operations list. It orders setup_net() and cleanup_net() with parallel {un,}register_pernet_operations() calls, so ->exit{,batch} methods of the same pernet operations are executed for a dying net, as were used to call ->init methods, even after the net namespace is unlinked from net_namespace_list in cleanup_net(). But there are several problems with scalability. The first one is that more than one net can't be created or destroyed at the same moment on the node. For big machines with many cpus running many containers it's very sensitive. The second one is that it's need to synchronize_rcu() after net is removed from net_namespace_list(): Destroy net_ns: cleanup_net() mutex_lock(&net_mutex) list_del_rcu(&net->list) synchronize_rcu() <--- Sleep there for ages list_for_each_entry_reverse(ops, &pernet_list, list) ops_exit_list(ops, &net_exit_list) list_for_each_entry_reverse(ops, &pernet_list, list) ops_free_list(ops, &net_exit_list) mutex_unlock(&net_mutex) This primitive is not fast, especially on the systems with many processors and/or when preemptible RCU is enabled in config. So, all the time, while cleanup_net() is waiting for RCU grace period, creation of new net namespaces is not possible, the tasks, who makes it, are sleeping on the same mutex: Create net_ns: copy_net_ns() mutex_lock_killable(&net_mutex) <--- Sleep there for ages I observed 20-30 seconds hangs of "unshare -n" on ordinary 8-cpu laptop with preemptible RCU enabled after CRIU tests round is finished. The solution is to convert net_mutex to the rw_semaphore and add fine grain locks to really small number of pernet_operations, what really need them. Then, pernet_operations::init/::exit methods, modifying the net-related data, will require down_read() locking only, while down_write() will be used for changing pernet_list (i.e., when modules are being loaded and unloaded). This gives signify performance increase, after all patch set is applied, like you may see here: %for i in {1..10000}; do unshare -n bash -c exit; done *before* real 1m40,377s user 0m9,672s sys 0m19,928s *after* real 0m17,007s user 0m5,311s sys 0m11,779 (5.8 times faster) This patch starts replacing net_mutex to net_sem. It adds rw_semaphore, describes the variables it protects, and makes to use, where appropriate. net_mutex is still present, and next patches will kick it out step-by-step.

net: make getname() functions return length rather than use int* parameter
Changes since v1: Added changes in these files: drivers/infiniband/hw/usnic/usnic_transport.c drivers/staging/lustre/lnet/lnet/lib-socket.c drivers/target/iscsi/iscsi_target_login.c drivers/vhost/net.c fs/dlm/lowcomms.c fs/ocfs2/cluster/tcp.c security/tomoyo/network.c Before: All these functions either return a negative error indicator, or store length of sockaddr into "int *socklen" parameter and return zero on success. "int *socklen" parameter is awkward. For example, if caller does not care, it still needs to provide on-stack storage for the value it does not need. None of the many FOO_getname() functions of various protocols ever used old value of *socklen. They always just overwrite it. This change drops this parameter, and makes all these functions, on success, return length of sockaddr. It's always >= 0 and can be differentiated from an error. Tests in callers are changed from "if (err)" to "if (err < 0)", where needed. rpc_sockname() lost "int buflen" parameter, since its only use was to be passed to kernel_getsockname() as &buflen and subsequently not used in any way. Userspace API is not changed. text data bss dec hex filename 30108430 2633624 873672 33615726 200ef6e vmlinux.before.o 30108109 2633612 873672 33615393 200ee21 vmlinux.o Signed-off-by: Denys Vlasenko <dvlasenk@redhat.com> CC: David S.

unify {de,}mangle_poll(), get rid of kernel-side POLL...
except, again, POLLFREE and POLL_BUSY_LOOP. With this, we finally get to the promised end result: - POLL{IN,OUT,...} are plain integers and *not* in __poll_t, so any stray instances of ->poll() still using those will be caught by sparse. - eventpoll.c and select.c warning-free wrt __poll_t - no more kernel-side definitions of POLL... - userland ones are visible through the entire kernel (and used pretty much only for mangle/demangle) - same behavior as after the first series (i.e. sparc et.al. epoll(2) working correctly).

vfs: do bulk POLL* -> EPOLL* replacement
This is the mindless scripted replacement of kernel use of POLL* variables as described by Al, done by this script: for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'` for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done done with de-mangling cleanups yet to come. NOTE! On almost all architectures, the EPOLL* constants have the same values as the POLL* constants do. But they keyword here is "almost". For various bad reasons they aren't the same, and epoll() doesn't actually work quite correctly in some cases due to this on Sparc et al. The next patch from Al will sort out the final differences, and we should be all done. Scripted-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

Daniel Borkmann says: ==================== pull-request: bpf 2018-02-09 The following pull-request contains BPF updates for your *net* tree. The main changes are: 1) Two fixes for BPF sockmap in order to break up circular map references from programs attached to sockmap, and detaching related sockets in case of socket close() event. For the latter we get rid of the smap_state_change() and plug into ULP infrastructure, which will later also be used for additional features anyway such as TX hooks. For the second issue, dependency chain is broken up via map release callback to free parse/verdict programs, all from John. 2) Fix a libbpf relocation issue that was found while implementing XDP support for Suricata project. Issue was that when clang was invoked with default target instead of bpf target, then various other e.g. debugging relevant sections are added to the ELF file that contained relocation entries pointing to non-BPF related sections which libbpf trips over instead of skipping them. Test cases for libbpf are added as well, from Jesper. 3) Various misc fixes for bpftool and one for libbpf: a small addition to libbpf to make sure it recognizes all standard section prefixes. Then, the Makefile in bpftool/Documentation is improved to explicitly check for rst2man being installed on the system as we otherwise risk installing empty man pages; the man page for bpftool-map is corrected and a set of missing bash completions added in order to avoid shipping bpftool where the completions are only partially working, from Quentin. 4) Fix applying the relocation to immediate load instructions in the nfp JIT which were missing a shift, from Jakub. 5) Two fixes for the BPF kernel selftests: handle CONFIG_BPF_JIT_ALWAYS_ON=y gracefully in test_bpf.ko module and mark them as FLAG_EXPECTED_FAIL in this case; and explicitly delete the veth devices in the two tests test_xdp_{meta,redirect}.sh before dismantling the netnses as when selftests are run in batch mode, then workqueue to handle destruction might not have finished yet and thus veth creation in next test under same dev name would fail, from Yonghong. 6) Fix test_kmod.sh to check the test_bpf.ko module path before performing an insmod, and fallback to modprobe. Especially the latter is useful when having a device under test that has the modules installed instead, from Naresh. ==================== Signed-off-by: David S. Miller <davem@davemloft.net> |

This request is late, apologies.
But it's also a fairly small update this time around. Some cleanup, RDMA fixes, overlayfs fixes, and a fix for an NFSv4 state bug. The bigger deal for nfsd this time around is Jeff Layton's already-merged i_version patches. This series has a minor conflict with that one, and the resolution should be obvious.

cpufreq: Add and use cpufreq_for_each_{valid_,}entry_idx()
Pointer subtraction is slow and tedious. Therefore, replace all instances where cpufreq_for_each_{valid_,}entry loops contained such substractions with an iteration macro providing an index to the frequency_table entry.

RISC-V changes for 4.16
This tag contains the fixes we'd like to target for the 4.16 merge window. It's not as much as I was originally hoping to do but between glibc, the chip, and FOSDEM there just wasn't enough time to get everything put together. As such, this merge window is essentially just going to be small changes. This includes mostly cleanups: * A build fix failure to the audit test cases. RISC-V doesn't have renameat because the generic syscall ABI moved to renameat2 by the time of our port. The syscall audit test cases don't understand this, so I added a trivial fix. This went through mailing list review during the 4.15 merge window, but nobody has picked it up so I think it's best to just do this here. * The removal of our command-line argument processing code. The "mem_end" stuff was broken and the rest duplicated generic device tree code. The generic code was already being called. * Some unused/redundant code has been removed, including __ARCH_HAVE_MMU, current_pgdir, and the initialization of init_mm.pgd. * SUM is disabled upon taking a trap, which means that user memory is protected during traps taking inside copy_{to,from}_user(). * The sptbr CSR has been renamed to satp in C code. We haven't changed the assembly code in order to maintain compatibility with binutils 2.29, which doesn't understand the new name. Additionally, we're adding some new features: * Basic ftrace support, thanks to Alan Kao! * Support for ZONE_DMA32. This is necessary for all the normal reasons, but also to deal with a deficiency in the Xilinx PCIe controller we're using on our FPGA-based systems. While the ZONE_DMA32 addition should be sufficient for most uses, it doesn't complete the fix for the Xilinx controller. * TLB shootdowns now only target the harts where they're necessary, instead of applying to all harts in the system. These patches have all been sitting on our linux-next branch for a while now. Due to time constraints this is all I feel comfortable submitting during the 4.16 merge window, hopefully we'll do better next time! -----BEGIN PGP SIGNATURE----- iQJHBAABCAAxFiEEAM520YNJYN/OiG3470yhUCzLq0EFAlp7N2gTHHBhbG1lckBk YWJiZWx0LmNvbQAKCRDvTKFQLMurQX8kD/4xxw6TuuESmDXxAQPQ+S8J98uKRfAF 9kMMzJJARcW5sT1vo3pKpE8+Ss0Hy2fIcaYsw5Je/Yl7vdAy/Dk7X3/mx7mxf5BP 8m2cSd7DFLLLhntZTbr1Y5fJ6awFLtzI46zn/SzTdTatLWKXNLS5wmPKE33ddq/C iTi4k/as8E/vuNtuPy1GsOF0gICpZ2xB4YoMwTgWfpxTekBkUktO3EOHmZTwQEEM U1muB+4WoqusbBt6cP3Q7cUF3b6aMVSevWnywZGkD+yWOGRXTVzMgT7R4YlKEOre OQypZocYUbRmZQMZACKpgHIcOZpePaSTIQ2zzhXEPVGB0XAHtMRnAaVtwPxwG6c4 EThDCN9ldShutKqT4XilHrh5gf0sy7qG0PIidPhMmXH9LCeTSAU4VdISJP1jkq19 chiMHlf6+/DhikyiH0+lK/MX8vQMt6UJL1SlRKO/c2FxxKAZKnENJ+tuAlkAlwoC gnvZsE5BUYw1ptRHXR0d5C4m8M2M9LPZfpWYcg+1mRO9EA+kt0XCupL7RsrdFuoa FCVEhP/JMaiX0JtmAHfVIU0yNGjH3b5xi3FoGk2Aoj/c8O3F5YcwT5C5nO+jpv32 n9vyMR20/721+yA2dFIlq4DnelwdZczOTqrcDYJrLxXzk8OXUFFffbe4kbDCxp34 WniBxwnY9BF25g== =cNRH -----END PGP SIGNATURE----- Merge tag 'riscv-for-linus-4.16-merge_window' of git://git.kernel.org/pub/scm/linux/kernel/git/palmer/riscv-linux Pull RISC-V updates from Palmer Dabbelt: "This contains the fixes we'd like to target for the 4.16 merge window.

SUNRPC: Queue latency-sensitive socket tasks to xprtiod
The response to a write_space notification is very latency sensitive, so we should queue it to the lower latency xprtiod_workqueue.

x86: hibernate: fix swsusp_arch_resume() prototype
The declaration for swsusp_arch_resume() marks it as 'asmlinkage', but the definition in x86-32 does not, and it fails to include the header with the declaration. This leads to a warning when building with link-time-optimizations: kernel/power/power.h:108:23: error: type of 'swsusp_arch_resume' does not match original declaration [-Werror=lto-type-mismatch] extern asmlinkage int swsusp_arch_resume(void); ^ arch/x86/power/hibernate_32.c:148:0: note: 'swsusp_arch_resume' was previously declared here int swsusp_arch_resume(void) This moves the declaration into a globally visible header file and fixes up both x86 definitions to match it.

netfilter: nf_flow_offload: fix use-after-free and a resource leak
flow_offload_del frees the flow, so all associated resource must be freed before. Since the ct entry in struct flow_offload_entry was allocated by flow_offload_alloc, it should be freed by flow_offload_free to take care of the error handling path when flow_offload_add fails. While at it, make flow_offload_del static, since it should never be called directly, only from the gc step Signed-off-by: Felix Fietkau <nbd@nbd.name> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> |

ACPI: SPCR: Make SPCR available to x86
SPCR is currently only enabled or ARM64 and x86 can use SPCR to setup an early console. General fixes include updating Documentation & Kconfig (for x86), updating comments, and changing parse_spcr() to acpi_parse_spcr(), and earlycon_init_is_deferred to earlycon_acpi_spcr_enable to be more descriptive. On x86, many systems have a valid SPCR table but the table version is not 2 so the table version check must be a warning. On ARM64 when the kernel parameter earlycon is used both the early console and console are enabled. On x86, only the earlycon should be enabled by by default. Modify acpi_parse_spcr() to allow options for initializing the early console and console separately.

pipe: reject F_SETPIPE_SZ with size over UINT_MAX
A pipe's size is represented as an 'unsigned int'. As expected, writing a value greater than UINT_MAX to /proc/sys/fs/pipe-max-size fails with EINVAL. However, the F_SETPIPE_SZ fcntl silently truncates such values to 32 bits, rather than failing with EINVAL as expected. (It *does* fail with EINVAL for values above (1 << 31) but <= UINT_MAX.) Fix this by moving the check against UINT_MAX into round_pipe_size() which is called in both cases.
