2018-03-05physmem: keep only one physmem_mainDamjan Marion1-0/+1
We don't need per vlib_main physmem_main, so keep it separatelly instead of trying to keep them in sync. Change-Id: I0fbeecf4d9672d31af7a43c640a7d8f05dd6e46f Signed-off-by: Damjan Marion <damarion@cisco.com>
2018-02-06vlib: epoll on worker threadsDamjan Marion2-34/+152
This patch teaches worer threads to sleep and to be waken up by kernel if there is activity on file desctiptors assigned to that thread. It also adds counters to epoll file descriptors and new debug cli 'show unix file'. Change-Id: Iaf67869f4aa88ff5b0a08982e1c08474013107c4 Signed-off-by: Damjan Marion <damarion@cisco.com>
2018-01-30VPP-899: Run VPP under SELinuxBilly McFall1-4/+20
Add an SELinux profile such that VPP can run under SELinux on RPM based platforms. The SELinux Policy is currently only implemented for RPM packages, specifically, Fedora, CentOS and RHEL. Doxygen User Documentation has been included (selinux_doc.md). Once some discussion on file locations has completed (see vpp-devlist), updates to the Debug CLI documentation will also need to be updated. Additional changes: Patch Set 2: - Rework selinux_doc.md such that each line is only 80 characters instead of each sentence on a line. Made additonal minor chnages to the text. - Update vHost Debug CLI documentation to reflex new socket location. Cleaned up some text from when I originally wrote it, to better reflex proper use. - Update exec Debug CLI documentation to be more inline with suggested helptext, added text regarding recommended script file location. - For Debian builds, create the /var/log/vpp/ directory. I don't use Debian very much, so please pay extra attention to build-data/platforms.mk and build-root/deb/debian/.gitignore. - Per discussion on VPP call, changed the default log location to /var/log/vpp/vpp.log. - Changed the socket location for vHost in AutoConfig to /var/run/vpp/. Patch Set 3: - Update selinux_doc.md based on comments. Change-Id: I400520dc33f1ca51012d09ef8fe5a7b7b96c631e Signed-off-by: Billy McFall <bmcfall@redhat.com>

2017-11-13Instead of a min term size, use a default (VPP-1061)Chris Luke1-16/+21
- In the bug report, Docker was sometimes giving shells a 0,0 terminal size. The minimum-term-size logic meant that VPP assumed the terminal had 1 row. The pager functioned, but of course overwrote the one line with its own prompt. - Instead of a minimum size, always use a default size when the either terminal dimension is 0.

2017-09-22Fix vpp "unix interactive" when running under emacs + gdbDave Barach1-3/+8

2017-09-21vppctl,cli: Improve non-interactive vppctl (VPP-944)Chris Luke1-51/+308
Short version: Make vppctl behave as expected when run from scripts, or without a controlling terminal, and especially when using it with VPP commands on its command line ("non-interactively"). In particular, prevent the welcome banner and VPP CLI prompt from being sent by VPP when being used in these ways. vppctl ------ - Improve vppctl's detection of non-interactive sessions. - Pass non-interactiveness in the terminal type telnet option as a value distinct from "dumb" (which means non-ANSI capable.) - Make tty setup handling more robust. - Only send non-interactive command once we've sent the terminal type, to ensure correct event sequence; we need the VPP cli session to be in line-by-line mode. - Ignore stdin when it looks something like /dev/null. - Skip NUL bytes received from VPP. VPP CLI ------- - Detect "non-interactive" terminal types and set session parameters accordingly. - Add an "interactive" flag that controls whether the welcome banner and CLI prompt are sent. - Detect if telnet options processing switched us into line mode and act accordingly for the rest of the current input buffer. This was causing the command string to be echoed by the CLI editor code. - For non-interactive sessions, send a NUL byte after the input buffer has been processed. This is because vppctl depends on seeing traffic before it will try to close the session; a command with no output would cause it to hang. NUL bytes are ignored by all decent terminals, but we have vppctl strip them out anyway. - Prevent certain commands from running in non-interactive sessions since they manipulate interactive-related features. - For interactive sessions, quench the prompt that prints on VPP shutdown. - Detect and handle socket errors in the CLI; sessions were leaking. - Pevent SIGPIPE from ever being raised; handle EPIPE instead. We don't need VPP to die just because a socket closed just before we try to write to it! - Add a command to dump a list of current CLI sessions; mostly this was to detect session leakage, but it may have some general utility.

2017-09-20CLI: fix segfault when browsing an empty historyYoann Desmouceaux1-3/+1

2017-07-10vlib: store buffer memory information in the buffer_mainDamjan Marion1-9/+0
Currently, buffer index is calculated as a offset to the physmem region shifted by log2_cacheline size. When DPDK is used we "hack" physmem data with information taken from dpdk mempool. This makes physmem code not usable with DPDK. This change makes buffer memory start and size independent of physmem basically allowing physmem to be used when DPDK plugin is loaded.

2017-07-06unix: mkdir VPP_RUN_DIR before opening a socket in itChris Luke3-0/+30
Change https://gerrit.fd.io/r/#/c/7230/ added a Unix domain CLI socket in the default startup.conf; however unless you had previously run VPP with the DPDK plugin enabled the directory that it is created in. /run/vpp, would not exist and startup would fail. This directory is typically hosted in a tmpfs ramdisk and is thus ephemeral. This patch adds a function that attempts to mkdir VPP_RUN_DIR and uses it in both the DPDK plugin and the CLI code if the CLI socket is to be created in that directory.

This patch deprecates stack-based thread identification, Also removes requirement that thread stacks are adjacent.

Using word "cpu" is misleading here as thread can be migrated ti different CPU, and also it is not related to linux cpu index.

2017-03-02Clean up binary api message handler registration issuesDave Barach1-7/+24
Removed a fair number of "BUG" message handlers, due to conflicts with actual message handlers in api_format.c.

2017-02-22VPP-635: CLI Memory leak with invalid parameterBilly McFall1-6/+16
In the CLI parsing, below is a common pattern: /* Get a line of input. */ if (!unformat_user (input, unformat_line_input, line_input)) return 0; while (unformat_check_input (line_input) != UNFORMAT_END_OF_INPUT) { if (unformat (line_input, "x")) x = 1; : else return clib_error_return (0, "unknown input `%U'", format_unformat_error, line_input); } unformat_free (line_input); The 'else' returns if an unknown string is encountered. There a memory leak because the 'unformat_free(line_input)' is not called. There is a large number of instances of this pattern. Replaced the previous pattern with: /* Get a line of input. */ if (!unformat_user (input, unformat_line_input, line_input)) return 0; while (unformat_check_input (line_input) != UNFORMAT_END_OF_INPUT) { if (unformat (line_input, "x")) x = 1; : else { error = clib_error_return (0, "unknown input `%U'", format_unformat_error, line_input); goto done: } } /* ...Remaining code... */ done: unformat_free (line_input); return error; } In multiple files, 'unformat_free (line_input);' was never called, so there was a memory leak whether an invalid string was entered or not. Also, there were multiple instance where: error = clib_error_return (0, "unknown input `%U'", format_unformat_error, line_input); used 'input' as the last parameter instead of 'line_input'. The result is that output did not contain the substring in error, instead just an empty string. Fixed all of those as well. There are a lot of file, and very mind numbing work, so tried to keep it to a pattern to avoid mistakes.

2017-02-03Plugin infrastructure improvementsDamjan Marion3-60/+318
This patch replaces requirement for vlib_plugin_register function in the plugin so file and introduces new macro: VLIB_PLUGIN_REGISTER () = { .version = "version string", .version_required = "requred version", .default_disabled = 1, .early_init = "early_init_function_name", }; Plugin will nor be loaded if .default_disabled is set to 1 unless explicitely enabled in startup.conf. If .verstion_required is set, plugin will not be loaded if there is version mismatch between plugin and vpp. This can be bypassed by setting "skip-version-check" for specific plugin. If .early-init string is present, plugin loader will try to resolve this specific symbol in the plugin namespace and make a function call. Following startup.conf configuration is added: plugins { path /path/to/plugin/directory plugin ila_plugin.so { enable skip-version-check } plugin acl_plugin.so { disable } } Change-Id: I706c691dd34d94ffe9e02b59831af8859a95f061 Signed-off-by: Damjan Marion <damarion@cisco.com>
