Key changes: - Add new Git class (Git.h/cpp) providing a simple interface for Git operations: init, commit, log, show, resolveRef, getHead, hasCommits - Use folly::Subprocess with full path /usr/bin/git for all Git commands - Replace revision files (agent-rN.conf + symlink) with atomic writes to agent.conf tracked in a local Git repository - Use Git commit SHAs as revision identifiers instead of rN format - Update RevisionList validation to accept Git SHAs (7+ hex chars) Repository initialization: - Automatically initialize Git repo if it doesn't exist - Automatically create initial commit if repo has no commits but config file exists - Use --shared=group flag and umask 0002 to ensure .git directory is group-writable when /etc/coop is group-writable Commands updated: - config history: Shows Git commit log with SHA, author, timestamp, message - config session diff: Uses git show to compare commits - config session commit: Creates Git commits with username as author - config rollback: Reads config from Git history and creates new commit Test updates: - Update all CLI config tests to use Git-based setup - Initialize Git repo and create initial commit in test fixtures --- cmake/CliFboss2.cmake | 2 + cmake/CliFboss2Test.cmake | 1 + fboss/cli/fboss2/BUCK | 2 + .../config/history/CmdConfigHistory.cpp | 131 +--- .../config/rollback/CmdConfigRollback.cpp | 20 +- .../config/session/CmdConfigSessionDiff.cpp | 114 +-- fboss/cli/fboss2/session/ConfigSession.cpp | 423 +++++------ fboss/cli/fboss2/session/ConfigSession.h | 92 +-- fboss/cli/fboss2/session/Git.cpp | 312 ++++++++ fboss/cli/fboss2/session/Git.h | 146 ++++ fboss/cli/fboss2/test/BUCK | 1 + .../cli/fboss2/test/CmdConfigHistoryTest.cpp | 230 +++--- .../CmdConfigInterfaceDescriptionTest.cpp | 32 +- ...onfigInterfaceSwitchportAccessVlanTest.cpp | 61 +- .../test/CmdConfigQosBufferPoolTest.cpp | 55 +- .../fboss2/test/CmdConfigSessionDiffTest.cpp | 151 ++-- .../cli/fboss2/test/CmdConfigSessionTest.cpp | 677 +++++++----------- fboss/cli/fboss2/test/GitTest.cpp | 125 ++++ fboss/cli/fboss2/test/TestableConfigSession.h | 11 +- fboss/cli/fboss2/utils/CmdUtils.cpp | 39 +- 20 files changed, 1493 insertions(+), 1132 deletions(-) create mode 100644 fboss/cli/fboss2/session/Git.cpp create mode 100644 fboss/cli/fboss2/session/Git.h create mode 100644 fboss/cli/fboss2/test/GitTest.cpp diff --git a/cmake/CliFboss2.cmake b/cmake/CliFboss2.cmake index 615f1e39d15ea..f7f19192901ed 100644 --- a/cmake/CliFboss2.cmake +++ b/cmake/CliFboss2.cmake @@ -650,6 +650,8 @@ add_library(fboss2_config_lib fboss/cli/fboss2/commands/config/session/CmdConfigSessionDiff.cpp fboss/cli/fboss2/session/ConfigSession.h fboss/cli/fboss2/session/ConfigSession.cpp + fboss/cli/fboss2/session/Git.h + fboss/cli/fboss2/session/Git.cpp fboss/cli/fboss2/utils/InterfaceList.h fboss/cli/fboss2/utils/InterfaceList.cpp fboss/cli/fboss2/CmdListConfig.cpp diff --git a/cmake/CliFboss2Test.cmake b/cmake/CliFboss2Test.cmake index f1d9dbcce2274..9940f3572ba7d 100644 --- a/cmake/CliFboss2Test.cmake +++ b/cmake/CliFboss2Test.cmake @@ -77,6 +77,7 @@ add_executable(fboss2_cmd_test # fboss/cli/fboss2/test/CmdShowTransceiverTest.cpp - excluded (depends on configerator bgp namespace) fboss/cli/fboss2/test/CmdStartPcapTest.cpp fboss/cli/fboss2/test/CmdStopPcapTest.cpp + fboss/cli/fboss2/test/GitTest.cpp fboss/cli/fboss2/test/PortMapTest.cpp ) diff --git a/fboss/cli/fboss2/BUCK b/fboss/cli/fboss2/BUCK index fb00d6a233708..832b10a47b73f 100644 --- a/fboss/cli/fboss2/BUCK +++ b/fboss/cli/fboss2/BUCK @@ -864,6 +864,7 @@ cpp_library( "commands/config/session/CmdConfigSessionCommit.cpp", "commands/config/session/CmdConfigSessionDiff.cpp", "session/ConfigSession.cpp", + "session/Git.cpp", "utils/InterfaceList.cpp", ], headers = [ @@ -882,6 +883,7 @@ cpp_library( "commands/config/session/CmdConfigSessionCommit.h", "commands/config/session/CmdConfigSessionDiff.h", "session/ConfigSession.h", + "session/Git.h", "utils/InterfaceList.h", ], exported_deps = [ diff --git a/fboss/cli/fboss2/commands/config/history/CmdConfigHistory.cpp b/fboss/cli/fboss2/commands/config/history/CmdConfigHistory.cpp index e6a950462f6d0..2ad6bf9f5a9fb 100644 --- a/fboss/cli/fboss2/commands/config/history/CmdConfigHistory.cpp +++ b/fboss/cli/fboss2/commands/config/history/CmdConfigHistory.cpp @@ -9,120 +9,23 @@ */ #include "fboss/cli/fboss2/commands/config/history/CmdConfigHistory.h" -#include -#include -#include -#include #include -#include -#include #include -#include #include "fboss/cli/fboss2/session/ConfigSession.h" #include "fboss/cli/fboss2/utils/Table.h" -namespace fs = std::filesystem;

Previously, whoever committed last would overwrite changes of other users that committed before them. This commit adds a `config session rebase` command that: 1. Takes the diff between the config as of the base commit and the session 2. Re-applies this diff on top of the current HEAD (similar to git rebase) 3. Uses a recursive 3-way merge algorithm for JSON objects 4. Detects and reports conflicts at specific JSON paths 5. Updates the session's base to the current HEAD on success The 3-way merge algorithm handles: - Objects: recursively merges each key - Arrays: element-by-element merge if sizes match - Scalars: conflict if both head and session changed differently from base Add unit tests covering: - Successful rebase with non-conflicting changes - Rebase failure when changes conflict - Rebase not needed when session is already up-to-date NOS-3962 #done --- cmake/CliFboss2.cmake | 2 + fboss/cli/fboss2/BUCK | 2 + fboss/cli/fboss2/CmdHandlerImplConfig.cpp | 5 + fboss/cli/fboss2/CmdListConfig.cpp | 7 + .../config/session/CmdConfigSessionRebase.cpp | 30 ++ .../config/session/CmdConfigSessionRebase.h | 39 +++ fboss/cli/fboss2/session/ConfigSession.cpp | 222 ++++++++++++++- fboss/cli/fboss2/session/ConfigSession.h | 15 +- .../cli/fboss2/test/CmdConfigSessionTest.cpp | 262 ++++++++++++++++++ .../test_config_concurrent_sessions.py | 155 +++++++++++ 10 files changed, 735 insertions(+), 4 deletions(-) create mode 100644 fboss/cli/fboss2/commands/config/session/CmdConfigSessionRebase.cpp create mode 100644 fboss/cli/fboss2/commands/config/session/CmdConfigSessionRebase.h create mode 100644 fboss/oss/cli_tests/test_config_concurrent_sessions.py diff --git a/cmake/CliFboss2.cmake b/cmake/CliFboss2.cmake index f7f19192901ed..bc4c9cb6b105b 100644 --- a/cmake/CliFboss2.cmake +++ b/cmake/CliFboss2.cmake @@ -648,6 +648,8 @@ add_library(fboss2_config_lib fboss/cli/fboss2/commands/config/session/CmdConfigSessionCommit.cpp fboss/cli/fboss2/commands/config/session/CmdConfigSessionDiff.h fboss/cli/fboss2/commands/config/session/CmdConfigSessionDiff.cpp + fboss/cli/fboss2/commands/config/session/CmdConfigSessionRebase.h + fboss/cli/fboss2/commands/config/session/CmdConfigSessionRebase.cpp fboss/cli/fboss2/session/ConfigSession.h fboss/cli/fboss2/session/ConfigSession.cpp fboss/cli/fboss2/session/Git.h diff --git a/fboss/cli/fboss2/BUCK b/fboss/cli/fboss2/BUCK index 832b10a47b73f..b89d4ea98bfb2 100644 --- a/fboss/cli/fboss2/BUCK +++ b/fboss/cli/fboss2/BUCK @@ -863,6 +863,7 @@ cpp_library( "commands/config/rollback/CmdConfigRollback.cpp", "commands/config/session/CmdConfigSessionCommit.cpp", "commands/config/session/CmdConfigSessionDiff.cpp", + "commands/config/session/CmdConfigSessionRebase.cpp", "session/ConfigSession.cpp", "session/Git.cpp", "utils/InterfaceList.cpp", @@ -882,6 +883,7 @@ cpp_library( "commands/config/rollback/CmdConfigRollback.h", "commands/config/session/CmdConfigSessionCommit.h", "commands/config/session/CmdConfigSessionDiff.h", + "commands/config/session/CmdConfigSessionRebase.h", "session/ConfigSession.h", "session/Git.h", "utils/InterfaceList.h", diff --git a/fboss/cli/fboss2/CmdHandlerImplConfig.cpp b/fboss/cli/fboss2/CmdHandlerImplConfig.cpp index 515f4dbb239e4..fcb72aa0d9bb3 100644 --- a/fboss/cli/fboss2/CmdHandlerImplConfig.cpp +++ b/fboss/cli/fboss2/CmdHandlerImplConfig.cpp @@ -12,6 +12,7 @@ // Current linter doesn't properly handle the template functions which need the // following headers +// NOLINTBEGIN(misc-include-cleaner) // @lint-ignore-every CLANGTIDY facebook-unused-include-check #include "fboss/cli/fboss2/commands/config/CmdConfigAppliedInfo.h" #include "fboss/cli/fboss2/commands/config/CmdConfigReload.h" @@ -27,6 +28,8 @@ #include "fboss/cli/fboss2/commands/config/rollback/CmdConfigRollback.h" #include "fboss/cli/fboss2/commands/config/session/CmdConfigSessionCommit.h" #include "fboss/cli/fboss2/commands/config/session/CmdConfigSessionDiff.h" +#include "fboss/cli/fboss2/commands/config/session/CmdConfigSessionRebase.h" +// NOLINTEND(misc-include-cleaner) namespace facebook::fboss { @@ -54,6 +57,8 @@ template void CmdHandler::run();

`config vlan static-mac add ` - `config vlan static-mac delete ` These commands allow operators to configure static MAC address entries in the FBOSS switch configuration, which is useful for scenarios where MAC addresses need to be pinned to specific ports. Features: * VLAN ID validation (1-4094 range) * MAC address format validation * Port existence validation with automatic logical ID resolution * Duplicate entry detection for add operations * Integration with ConfigSession for proper config management Unit Tests: ``` ./fboss/oss/scripts/nhfboss-test.sh --timeout 30 --retry 0 --filter 'CmdConfigVlanStaticMac' Output: [==========] Running 33 tests from 1 test suite. ... [ PASSED ] 33 tests. ``` Manual CLI Testing: ``` $ fboss2-dev config vlan 2001 static-mac add 02:00:00:E2:E2:01 eth1/1/1 Successfully added static MAC entry: MAC 02:00:00:E2:E2:01 -> VLAN 2001, Port eth1/1/1 (ID 9) $ fboss2-dev config session commit Config session committed successfully as r77 and config reloaded. $ fboss2-dev config vlan 2001 static-mac delete 02:00:00:E2:E2:01 Successfully

This allows configuring per-port priority group settings for traffic prioritization and buffer management. New command: `config qos priority-group-policy group-id [ ...]` Where can be: - `min-limit-bytes` - `headroom-limit-bytes` - `resume-offset-bytes` - `static-limit-bytes` - `scaling-factor` (accepts `MMUScalingFactor` enum values like `ONE_HALF`, `TWO`, etc) - `buffer-pool-name` Multiple attributes can be set in a single command, or one at a time. The implementation doesn't declare the sub-subcommands in a conventional way in order to avoid an explosion of `.h` / `.cpp` pairs. Also updates `ConfigSession::restartAgent()` to use `sudo` for `systemctl restart` since the CLI may be run by non-root users. New end to end tests: ``` ====================================================================== CLI E2E Test: PFC Configuration ====================================================================== [Step 0] Cleaning up any existing test config...

Summary Implements new fboss2-dev CLI commands for configuring PFC (Priority Flow Control) settings on individual interfaces. This allows enabling/disabling PFC, setting watchdog parameters, and associating priority group policies with ports. The command uses a key-value pair syntax that allows setting multiple attributes in a single command: ``` config interface pfc-config [ ...] ``` Valid attributes: - `tx enabled|disabled` - Enable/disable PFC transmission - `rx enabled|disabled` - Enable/disable PFC reception - `tx-duration enabled|disabled` - Enable/disable TX duration - `rx-duration enabled|disabled` - Enable/disable RX duration - `priority-group-policy ` - Set priority group policy - `watchdog-detection-time ` - Set watchdog detection time - `watchdog-recovery-time ` - Set watchdog recovery time - `watchdog-recovery-action drop|no-drop` - Set watchdog recovery action # Test Plan End-to-end tests on fboss101: ``` ====================================================================== CLI E2E Test: PFC Configuration ====================================================================== [Step 0] Cleaning up any existing test config...

The first two end-to-end tests that were originally written in Python, along with helper functions, have been rewritten in C++, and can now run as a self-contained gtest binary, without depending on the fboss2-dev binary. Some fixes were necessary to make this work, so the CLI could be re-used as a library instead of being invoked as a subprocess: 1. Remove the `hasRun` static variable from `CmdHandler` - Previously, a static `hasRun` flag prevented commands from executing more than once per process - Now we wrap callbacks in `CmdSubcommands` to check `get_subcommands().empty()` to detect leaf commands, eliminating the need for static state 2. Throw exceptions instead of calling `exit(1)` in `CmdHandler` - `CmdHandler::run()` now rethrows exceptions instead of calling `exit(1)` - This allows tests to catch errors and verify exit codes - `Main.cpp` catches exceptions and returns exit code 1 3. Factor out `CLI::App` initialization into `CliAppInit.h` - Header-only `initApp()` function shared between `Main.cpp` and tests - Eliminates code duplication for CLI setup - This couldn't be packaged into a library of its own without going into circular dependency hell, hence why it's a header-only helper 4. Reset state in `ConfigSession::initializeSession()` - Clear `ConfigSession` attributes when creating a new session (when session file doesn't exist) - Allows re-using the same `ConfigSession` singleton after `commit()` 5. Update state in `ConfigSession::commit()` - Set `base_` to the new commit SHA after successful commit - Set `configLoaded_ = false` to force config reload on next access - Allows re-using the same `ConfigSession` singleton after `commit()` 6. Automatically initialize session in `ConfigSession::loadConfig()` - If session file doesn't exist (e.g., after commit deleted it), call `initializeSession()` to create a fresh session These changes allow the ConfigSession singleton to be properly reused across multiple CLI command invocations within the same process. Added new end-to-end tests in C++ that replace `test_config_interface_mtu.py` and `test_config_interface_description.py` (the Python scripts will be removed in a future PR soon). Sample output (simplified, without timestamps and other noise): ``` [==========] Running 2 tests from 2 test suites.

This controls whether packets are tagged or untagged when egressing the port. Where `` can be: - `tagged` - Packets egress with VLAN tag - `untagged` - Packets egress without VLAN tag This is a hitless configuration change (no agent restart required). ## 2. config l2 learning-mode Configures the L2 learning mode (`l2LearningMode` in `SwitchSettings`). This controls how the switch learns MAC addresses. Where `` can be: - `hardware` - MAC learning is performed by the hardware ASIC - `software` - MAC learning is performed by the software agent - `disabled` - MAC learning is disabled Note: Changing L2 learning mode requires an agent restart (not hitless) because the FBOSS agent does not permit changing this setting after initial config application. # Test Plan ## Unit tests **config vlan port taggingMode** (15 test cases): - Argument validation, mode conversion, error handling **config l2 learning-mode** (14 test cases): - Argument validation, mode conversion, error handling ## End-to-end tests **config vlan port taggingMode:** ``` ============================================================ CLI E2E Test: config vlan port taggingMode ============================================================ [Step 1] Finding an interface to test...

These commands allow configuring bidirectional mappings between codepoint values and internal traffic classes. New CLI commands: - DSCP maps (RFC 2474, values 0-63): - `config qos policy map dscp traffic-class ` - `config qos policy map traffic-class dscp ` - MPLS EXP maps (RFC 3032/5462, values 0-7): - `config qos policy map mpls-exp traffic-class ` - `config qos policy map traffic-class mpls-exp ` - DOT1P/PCP maps (802.1Q, values 0-7): - `config qos policy map dot1p traffic-class ` - `config qos policy map traffic-class dot1p ` The first command in each pair is additive (ingress classification - multiple codepoints can map to the same traffic class), while the second is not additive (egress rewrite - one traffic class maps to one codepoint value). # Test Plan New end to end tests: ``` Note: Google Test filter = *ConfigQosPolicyMapTest* [==========] Running 1 test from 1 test suite.

This is the first step in refactoring the CLI command registration system to avoid creating a monolithic include file. Changes: - Created 11 new .cpp files for stub commands that were missing them - Added template instantiations to 20 existing command .cpp files - Updated cmake/CliFboss2.cmake and fboss/cli/fboss2/BUCK build files - Deleted fboss/cli/fboss2/CmdHandlerImplConfig.cpp Each command .cpp file now includes CmdHandler.cpp and has its own explicit template instantiation, following the pattern: #include "fboss/cli/fboss2/CmdHandler.cpp" template void CmdHandler::run(); # Test Plan Ran all the unit tests. --- cmake/CliFboss2.cmake | 11 +- fboss/cli/fboss2/BUCK | 13 +-

This command allows users to discard any pending config session changes without committing them, providing a clean way to abandon a session and start fresh. ## Changes - Added CmdConfigSessionClear.h and CmdConfigSessionClear.cpp implementing the clear command - Registered the command in CmdListConfig.cpp under config session subcommands - Added unit tests in CmdConfigSessionTest.cpp covering: - Clearing an existing session removes both files - Clearing when no session exists (no-op) - Clearing with partial session state (only config file exists) - Added e2e test in ConfigSessionClearTest.cpp that creates a session and clears it # Test Plan New E2E and unit tests. ## Sample usage ``` [admin@fboss101 .fboss2]$ fboss2-dev config session clear Config session cleared successfully. [admin@fboss101 .fboss2]$ fboss2-dev config session clear No config session exists. Nothing to clear. ``` --- cmake/CliFboss2.cmake | 2 + cmake/CliFboss2Test.cmake | 2 + fboss/cli/fboss2/BUCK | 2 + fboss/cli/fboss2/CmdListConfig.cpp | 7 + .../config/session/CmdConfigSessionClear.cpp
