* m4: Test avx512 for x86 only.Cheng Li2022-09-271-2/+2

* acinclude: Improve vpopcntdq build check.Cian Ferriter2022-08-121-0/+29
| | | | | | | | | | | | | | | | | Support for vpopcntdq instruction generation by the compiler was already checked in the OVS_CHECK_AVX512 AC function by checking if the compiler accepted the -mavx512vpopcntdq option. However, there can be situations where the compiler supports vpopcntdq generation but the assembler doesn't support the instruction. The below OVS_CHECK_AVX512VPOPCNTDQ AC function will check for both compiler and assembler support for the vpopcntdq instruction.

* configure: explicitly disable avx512 if bintuils check failsHarry van Haaren2020-08-051-0/+4
| | | | | | | | | | | | | | This commit explicitly disables avx512f if the binutils assembler check fails to correctly assemble its input. Without this fix, there is a possibility that users can see undefined behaviour when compiling with -march=native on a CPU which supports avx512 and with a buggy binutils version (v2.30 and 2.31), without a backported fix, if the compiler's vectorizing optimizations convert scalar code to avx512 instructions.

* dpif-lookup: add avx512 gather implementation.Harry van Haaren2020-07-131-0/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds an AVX-512 dpcls lookup implementation. It uses the AVX-512 SIMD ISA to perform multiple miniflow operations in parallel. To run this implementation, the "avx512f" and "bmi2" ISAs are required. These ISA checks are performed at runtime while probing the subtable implementation. If a CPU does not provide both "avx512f" and "bmi2", then this code does not execute. The avx512 code is built as a separate static library, with added CFLAGS to enable the required ISA features. By building only this static library with avx512 enabled, it is ensured that the main OVS core library is *not* using avx512, and that OVS continues to run as before on CPUs that do not support avx512. The approach taken in this implementation is to use the gather instruction to access the packet miniflow, allowing any miniflow blocks to be loaded into an AVX-512 register. This maximizes the usefulness of the register, and hence this implementation handles any subtable with up to miniflow 8 bits. Note that specialization of these avx512 lookup routines still provides performance value, as the hashing of the resulting data is performed in scalar code, and compile-time loop unrolling occurs when specialized to miniflow bits. This commit checks at configure time if the assembling in use has a known bug in assembling AVX512 code. If this bug is present, all AVX512 code is disabled. Checking the version string of the binutils or assembler is not a good method to detect the issue, as back ported fixes would not be reflected.

* fatal-signal: Catch SIGSEGV and print backtrace.William Tu2019-09-271-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch catches the SIGSEGV signal and prints the backtrace using libunwind at the monitor daemon. This makes debugging easier when there is no debug symbol package or gdb installed on production systems. The patch works when the ovs-vswitchd compiles even without debug symbol (no -g option), because the object files still have function symbols. For example: |daemon_unix(monitor)|WARN|SIGSEGV detected, backtrace: |daemon_unix(monitor)|WARN|0x0000000000482752 <fatal_signal_handler+0x52> |daemon_unix(monitor)|WARN|0x00007fb4900734b0 <killpg+0x40> |daemon_unix(monitor)|WARN|0x00007fb49013974d <__poll+0x2d> |daemon_unix(monitor)|WARN|0x000000000052b348 <time_poll+0x108> |daemon_unix(monitor)|WARN|0x00000000005153ec <poll_block+0x8c> |daemon_unix(monitor)|WARN|0x000000000058630a <clean_thread_main+0x1aa> |daemon_unix(monitor)|WARN|0x00000000004ffd1d <ovsthread_wrapper+0x7d> |daemon_unix(monitor)|WARN|0x00007fb490b3b6ba <start_thread+0xca> |daemon_unix(monitor)|WARN|0x00007fb49014541d <clone+0x6d> |daemon_unix(monitor)|ERR|1 crashes: pid 122849 died, killed \ (Segmentation fault), core dumped, restarting However, if the object files' symbols are stripped, then we can only get init function plus offset value. This is still useful when trying to see if two bugs have the same root cause, Example: |daemon_unix(monitor)|WARN|SIGSEGV detected, backtrace: |daemon_unix(monitor)|WARN|0x0000000000482752 <_init+0x7d68a> |daemon_unix(monitor)|WARN|0x00007f5f7c8cf4b0 <killpg+0x40> |daemon_unix(monitor)|WARN|0x00007f5f7c99574d <__poll+0x2d> |daemon_unix(monitor)|WARN|0x000000000052b348 <_init+0x126280> |daemon_unix(monitor)|WARN|0x00000000005153ec <_init+0x110324> |daemon_unix(monitor)|WARN|0x0000000000407439 <_init+0x2371> |daemon_unix(monitor)|WARN|0x00007f5f7c8ba830 <__libc_start_main+0xf0> |daemon_unix(monitor)|WARN|0x0000000000408329 <_init+0x3261> |daemon_unix(monitor)|ERR|1 crashes: pid 106155 died, killed \ (Segmentation fault), core dumped, restarting Most C library functions are not async-signal-safe, meaning that it is not safe to call them from a signal handler, for example printf() or fflush(). To be async-signal-safe, the handler only collects the stack info using libunwind, which is signal-safe, and issues 'write' to the pipe, where the monitor thread reads and prints to ovs-vswitchd.log.

* Require Python 3 and remove support for Python 2.Ben Pfaff2019-09-271-81/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Python 2 reaches end-of-life on January 1, 2020, which is only a few months away. This means that OVS needs to stop depending on in the next release that should occur roughly that same time. Therefore, this commit removes all support for Python 2. It also makes Python 3 a mandatory build dependency. Some of the interesting consequences: - HAVE_PYTHON, HAVE_PYTHON2, and HAVE_PYTHON3 conditionals have been removed, since we now know that Python3 is available. - $PYTHON and $PYTHON2 are removed, and $PYTHON3 is always available. - Many tests for Python 2 support have been removed, and the ones that depended on Python 3 now run unconditionally. This allowed several macros in the testsuite to be removed, making the code clearer. This does make some of the changes to the testsuite files large due to indentation level changes. - #! lines for Python now use /usr/bin/python3 instead of /usr/bin/python. - Packaging depends on Python 3 packages.

* acinclude: Also use LIBS from dpkg pkg-configChristian Ehrhardt2019-02-131-78/+139
| | | | | | | | | | | | | | | | | | | | | | | | | DPDK 18.11 builds using the more modern meson build system no more provide the -ldpdk linker script. Instead it is expected to use pkgconfig for linker options as well. This change will set DPDK_LIB from pkg-config (if pkg-config was available) and since that already carries the whole-archive flags around the PMDs skips the further wrapping in more whole-archive if that is already part of DPDK_LIB. To work reliable in all environments this needs pkg-config 0.29.1. We want to be able to use PKG_CHECK_MODULES_STATIC which is not yet available in 0.24. Therefore update pkg.m4 to pkg-config 0.29.1. This should be backport-safe as these macro files are all versioned. autoconf is smart enough to check the version if you have it locally, and if the system's is higher, it will use that one instead.

* DNS: Add basic support for asynchronous DNS resolvingYifeng Sun2018-07-061-0/+10
| | | | | | | | | | | | | | | | | | | | | | This patch is a simple implementation for the proposal discussed in https://mail.openvswitch.org/pipermail/ovs-dev/2017-August/337038.html and https://mail.openvswitch.org/pipermail/ovs-dev/2017-October/340013.html. It enables ovs-vswitchd and other utilities to use DNS names when specifying OpenFlow and OVSDB remotes. Below are some of the features and limitations of this patch: - Resolving is asynchornous in daemon context, avoiding blocking main loop; - Resolving is synchronous in general utility context; - Both IPv4 and IPv6 are supported; - The resolving API is thread-safe; - Depends on the unbound library; - When multiple ip addresses are returned, only the first one is used; - /etc/nsswitch.conf isn't respected as unbound library doesn't look at it; - For async-resolving, caller need to retry later; there is no callback.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current intent for Open vSwitch is to maintain libopenvswitch ABI stability for minor versions, for example each release within the 2.7.z series. According to the following documentation, no changes to exported headers should be made. http://docs.openvswitch.org/en/latest/internals/contributing/libopenvswitch-abi/ However, it is occasionally necessary to make changes to {include/openvswitch,lib}/*.h headers to fix issues within a given release series. The current libtool tagging mechanism in the build system does not allow for this without creating a conflict between the libtool 'current' version and the next minor release of OVS. This patch modifies libopenvswitch build to include the MAJOR.MINOR release version in the libX name, and include the libtool CURRENT and OVS MICRO release in the libtool versioning tags to indicate library stability. The resulting format is "libfoo-X.Y.so.CURRENT.0.Z" for OVS release "X.Y.Z". Developers should still attempt to avoid introducing ABI-breaking changes within a particular OVS-X.Y release series, but if this is not possible this patch introduced a mechanism to allow an ABI-breaking fix to be introduced. In such a case, developers may update the libtool CURRENT version to indicate this breakage to library users. Signed-off-by: Joe Stringer <joe@ovn.org> Acked-by: Ben Pfaff <blp@ovn.org>

| | | | | | | | | | | Sphinx 1.1.3 on RHEL7 is able to properly build the documentation. Discovering fixed because 'sphinx-build v1.1.3' doesn't support '--version' option.

* libX: add new release / version info tagsAaron Conole2017-01-181-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit uses the $PACKAGE_VERSION automake variable to construct a release and version info combination which sets the library name to be: libfoo-$(OVS_MAJOR_VERSION).so.$(OVS_MINOR_VERSION).0.$(OVS_MICRO_VERSION) where formerly, it was always: libfoo.so.1.0.0 This allows releases of Open vSwitch libraries to reflect which specific versions they came with, and sets up a psuedo ABI-versioning scheme. In this fashion, future releases of Open vSwitch could be installed alongside older releases, allowing 3rd party utilities linked against previous versions to continue to function. ex: $ ldd /path/to/utility linux-vdso.so.1 (0x00007ffe92cf6000) libopenvswitch-2.so.6 => /lib64/libopenvswitch-2.so.6 (0x00007f733b7a3000) libssl.so.10 => /lib64/libssl.so.10 (0x00007f733b530000) ...

* m4: Rename compat.at to compat.m4.Ben Pfaff2016-02-262-2/+2
| | | | | | | This is used by both Autoconf and Autotest, so it doesn't make sense for it to have a .at (Autotest) extension. Signed-off-by: Ben Pfaff <blp@ovn.org>

* python: Fix xmlrpclib imports.Russell Bryant2016-01-201-0/+6
| | | | | | | | | | | | | | Fix imports of xmlrpclib to be compatible with Python 3. Python 2 had xmlrpclib (client) and SimpleXMLRPCServer (server). In Python 3, these have been renamed to xmlrpc.client and xmlrpc.server. The solution implemented here is to use the six library. It may seem excessive for this particular issue, but the six library provides helpers for Python 2 and 3 compatibility for many different issues. This is just the first of many uses of the six library. Signed-off-by: Russell Bryant <russell@ovn.org> Acked-by: Ben Pfaff <blp@ovn.org>

| | | | | | | | | | | | If flake8 is installed, run it at build time. Similar to most Makefile targets, run it once and then only run again if the files change. flake8 is set to ignore all error and warning types that currently occur. Future patches will remove items from the ignore list as they are resolved. Signed-off-by: Russell Bryant <russell@ovn.org> Acked-by: Ben Pfaff <blp@ovn.org>

| | | | | | | | | | | | | | | | | | | Add configuration option for enabling or disabling linking with libcap-ng. Since capabilities are a security feature, the libcapng option is handled as follows: - no option: use libcapng if it's present --disable-libcapng: do not use libcapng --enable-libcapng: do use libcapng and fail configuration if it's missing On Linux, not linking with libcapng makes all OVS daemons fail when --user option is specified.
