This may or may not allow an +attacker to learn information about the system clock at such +a resolution, depending on various issues such as network lag. +This information is available to anyone who monitors the network +somewhere between the attacked system and the destination server. +It may allow an attacker to find out how long a given +system has been running, and to distinguish several +systems running behind NAT and using the same IP address.

The idea is that a user can shut down + * a portable installation of Kicksecure by simply yanking the USB drive + * containing the installation from the computer. Tails provides essentially + * the same feature, however it is known for occasionally failing to do its + * job properly. + * + * The fact that we're triggering a shutdown when the device containing the + * root filesystem vanishes presents a number of significant challenges: + * + * - The device providing the entire operating system is gone. The only things + * we will still have left are the kernel, files loaded into RAM (for + * instance under /run), and anything that happens to still be in the + * system's disk cache. + * - Virtually any process on the system may abruptly crash at any time. This + * isn't just because applications may be unable to access files. The Linux + * kernel's virtual memory subsystem doesn't just page out RAM contents to a + * swap file, it will sometimes simply erase pages containing executable + * code from memory if it can reload that code from disk later when needed. + * If part of a program isn't present in memory, and then the root device + * vanishes, any attempt to use code in the absent part of the application + * will result in the application crashing. (Attempts to access data in RAM + * that happened to be paged out will result in a similar crash.) + * - We have no control over what is and isn't in the disk cache, which makes + * it unsafe to launch any dynamically linked executable. What happens if we + * need to load a missing part of libc? What if the dynamic linker itself + * needs loaded from disk? + * - Systemd could lock up at any time, since the init process isn't immune to + * having bits of it erased from RAM to free up memory. If systemd receives + * a SIGSEGV, rather than crashing (which would panic the kernel), it goes + * into an "emergency mode" that tries to keep the system as operational as + * possible even though PID 1 is now out of service. + * + * Circumventing this set of difficulties is not easy, and it might not even + * be entirely possible. To give our feature the highest chance of success: + * + * - We use memlockd to lock systemd and all libraries it depends on into + * memory. It can holds its own pretty well in the event of a segfault, but + * if its crash handler ends up re-segfaulting, that could get ugly. + * - We compile the utility at boot time, statically link it against all of + * its dependencies (really only one, glibc), and load it into /run. This + * allows for decent architecture independence while removing any dependency + * on anything that isn't in RAM, thus (hopefully!) making the process + * crash-immune. + * - Because we're static-linking against glibc, we cannot call anything + * defined in stdio.h. This is because glibc uses dlopen() to load iconv + * modules, which are used internally by glibc for locale support. Things + * defined in stdio.h may use iconv, so calling anything there will + * basically make our static-linked executable become dynamically linked, + * which could segfault it since the root filesystem is gone. We can't call + * anything that could touch Name Service Switch (NSS) either, but we have + * no need to do so, so we should be safe there. See + * https://stackoverflow.com/questions/57476533/why-is-statically-linking-glibc-discouraged + * - We can't use udev either because libudev is only available as a dynamic + * library. That means we have to listen to kernel uevents directly to + * determine when the root device vanishes.

When ssh-agent's matchwhitelist entry was commented out in commit 7a5f8b87af, permission-hardener began resetting it to restrictive defaults (744), preventing non-root users from executing ssh-agent. This broke split SSH functionality in Qubes OS for me because I was using Kicksecure in the vault qube, and ssh-agent runs under a non-root user in that configuration (see https://forum.qubes-os.org/t/split-ssh/19060).

`security-misc` source code repository builds three different software packages: + +* `security-misc-shared` +* `security-misc-desktop` +* `security-misc-server` + +The guiding principle has been: if there are no adverse effects, or if it is unclear whether a file belongs in the `desktop` or `server` package, then it will be placed in the `shared` package. + +The hash symbol ("`#`") is used as a separator character. + +Some clear examples where files belong only in `security-misc-desktop`: + +* `/usr/lib/NetworkManager/conf.d/80_ipv6-privacy#security-misc-desktop.conf` +* `/usr/lib/NetworkManager/conf.d/80_randomize-mac#security-misc-desktop.conf` +* `./usr/lib/systemd/networkd.conf.d/80_ipv6-privacy-extensions.conf#security-misc-desktop` + +This is because enabling IPv6 privacy extensions or MAC randomization on a server will not increase privacy but instead carries a high risk of breaking connectivity. + +A less clear example is `/etc/bluetooth/30_security-misc.conf#security-misc-desktop`. Also refer to the above chapter "Bluetooth Hardening". A server usually doesn't have Bluetooth, so on a server it may instead be useful to fully disable Bluetooth. + +Some clear examples where files belong only in `security-misc-shared`: + +`/etc/profile.d/30_security-misc.sh#security-misc-shared` indeed belongs in `security-misc-shared` and not `security-misc-desktop`. For the reason, see below. + +Other considerations have been: + +* Just because it's a server, it does not follow that there is no GUI (graphical user interface) desktop environment. +* Just because it's a desktop computer, it doesn't mean it's a GUI and not a CLI (command line interface). +* Therefore, the split is between `security-misc-desktop` and `security-misc-server`. +* Therefore, the split is not between `security-misc-gui` and `security-misc-cli`. + +\[1\] https://github.com/Kicksecure/security-misc/issues/187 + ## Related - Linux Kernel Runtime Guard (LKRG) diff --git

Two jobs - one per language - matching the source mix actually present in the repo: python: usr/lib/python3/dist-packages/fm_shim_frontend/ c-cpp: usr/src/security-misc/{emerg-shutdown,fm-shim-backend}.c Source files in this repo carry a '#' suffix per the genmkfile installable-routing convention; that suffix hides them from CodeQL's Python extractor (which discovers by file extension). Two helper scripts handle this: ci/codeql-prepare.sh - run via the reusable's pre-init hook; creates extension-clean symlinks for each '*.py#tag' source. ci/codeql-build.sh - manual build for c-cpp; installs build deps and runs gcc -c on each .c file. The C extractor traces compiler invocations rather than scanning by extension, so the tagged paths can be passed to gcc verbatim.

The motivating use case is also that CodeQL's CI compile path (ci/codeql-build.sh) was duplicating the gcc command, including ~70 hardening flags. With ~70 flags in two places, drift was a matter of when, not if. New helpers (no '.sh' extension to match the rest of usr/libexec/ security-misc/): usr/libexec/security-misc/compile-fm-shim-backend usr/libexec/security-misc/compile-emerg-shutdown Each is a pure compile - takes (source, output) positionals, runs gcc with the project's hardening flag set, exits non-zero on failure. No chmod, no mv, no install - the caller decides what to do with the binary. Consumers: build-fm-shim-backend - keeps mktemp/trap/chmod/mv lifecycle, delegates the gcc invocation. emerg-shutdown - keeps the dracut/config/memlockd/exec logic, delegates the gcc invocation. The hardening flag array and machine- type branching go away from this file. ci/codeql-build.sh - drops the inline gcc, calls both compile- helpers. Single source of truth: CI's hardening flags == runtime's. Also extends ci/codeql-prepare.sh to symlink '*.c#' to clean '*.c' names (in addition to '*.py#'). gcc selects driver behavior by file extension - a '*.c#' source is misclassified as a linker script ('file format not recognized'). Verified locally: with the symlinks in place, the helpers produce both binaries (fm-shim-backend dynamic 49 KB, emerg-shutdown static 875 KB) without warnings under x86_64-linux-gnu. Wires the c-cpp CodeQL job to run codeql-prepare.sh too via the reusable workflow's prepare-command hook. --- .github/workflows/codeql.yml | 5 + ci/codeql-build.sh | 49 +++++----- ci/codeql-prepare.sh | 30 +++--- debian/security-misc-shared.install | 2 + ...build-fm-shim-backend#security-misc-shared | 52 +---------- ...ompile-emerg-shutdown#security-misc-shared | 88 ++++++++++++++++++ ...mpile-fm-shim-backend#security-misc-shared | 91 +++++++++++++++++++ .../emerg-shutdown#security-misc-shared | 50 +--------- 8 files changed, 229 insertions(+), 138 deletions(-) create mode 100755 usr/libexec/security-misc/compile-emerg-shutdown#security-misc-shared create mode 100755 usr/libexec/security-misc/compile-fm-shim-backend#security-misc-shared diff --git a/.github/workflows/codeql.yml b/.github/workflows/codeql.yml index 4f145ab7..023e26b2 100644 --- a/.github/workflows/codeql.yml +++ b/.github/workflows/codeql.yml @@ -58,6 +58,11 @@ jobs: uses: org-ai-assisted/developer-meta-files/.github/workflows/codeql.yml@master with: language: c-cpp + ## prepare-command runs before init AND before the build + ## step; the build step (ci/codeql-build.sh) needs the clean + ## '*.c' symlinks the prep creates - gcc rejects '*.c#' + ## as not-a-C-file at link time. + prepare-command: bash ci/codeql-prepare.sh build-mode: manual build-command: bash ci/codeql-build.sh permissions: diff --git a/ci/codeql-build.sh b/ci/codeql-build.sh index 68dbcb49..08c3e151 100755 --- a/ci/codeql-build.sh +++ b/ci/codeql-build.sh @@ -7,17 +7,20 @@ ## CodeQL manual build for the C sources in this repo. ## -## The two C files use the genmkfile '#package-tag' filename -## convention (see ci/codeql-prepare.sh). gcc accepts those paths -## verbatim, so we hand them to the compiler unchanged - what matters -## for the C/C++ extractor is that gcc sees and parses each -## translation unit. +## Delegates the actual gcc invocations to the upstream compile +## helpers under usr/libexec/security-misc/.

Switch from plain pyflakes3 to 'flake8 --select=F'. pyflakes by design does not honor any suppression comment - not '# noqa', not '# pylint: disable', nothing. There is no escape hatch for intentional violations short of a code rewrite. flake8 wraps pyflakes (same F-class checks) and adds '# noqa' support, which is the standard pyflakes-aware suppression. '--select=F' restricts to F-class rules only (undefined names, unused imports, unused locals, ...) and skips E/W PEP8 style noise that would clash with the codebase's '##' block-comment convention (E266). 2. Apply '# noqa: F841 # pylint: disable=unused-variable' to the intentionally-retained QWindow reference in main(). The binding is required to keep the QWindow alive while app.exec_() is running (Qt does not always retain Python wrappers for top- level windows without a parent). Both pyflakes (F841) and pylint (unused-variable) flagged it as unused; per-tool pragmas are needed because the two tools do not share a common 'intentionally unused local' marker. Locally verified: 'flake8 --select=F' returns rc=0 against the prepared (symlinked) source paths after these changes. --- .github/workflows/lint-python.yml | 53 +++++++++++-------- .../fm_shim_frontend.py#security-misc-shared | 10 +++- 2 files changed, 40 insertions(+), 23 deletions(-) diff --git a/.github/workflows/lint-python.yml b/.github/workflows/lint-python.yml index 12478512..52c779a1 100644 --- a/.github/workflows/lint-python.yml +++ b/.github/workflows/lint-python.yml @@ -7,23 +7,32 @@ ## Simple Python lint for fm_shim_frontend. ## ## Scope is intentionally narrow: -## - usr/lib/python3/dist-packages/fm_shim_frontend/ (only +## - usr/lib/python3/dist-packages/fm_shim_frontend/ (the only ## Python in this repo) ## -## Two checks, both error-only (no style nitpicks): -## - pyflakes : undefined names, unused imports, undefined -## __all__, etc. Fast, low-noise. -## - pylint --errors : real issues (E*** rules) only.

The fuzz suite immediately found a real exploitable bug at introduction: an attacker who can deliver a URI with a single path component longer than NAME_MAX (255 bytes on Linux) crashed the process via an uncaught OSError(ENAMETOOLONG=36) from Path.exists(). Fixed by wrapping the exists() call in try/except OSError - any OSError is treated as 'non-existent, skip' (same path the False branch was already handling). The bug is reachable from an attacker process via the FileManager1 D-Bus surface (other desktop apps can pass URI lists). Severity: local DoS of the fm-shim-frontend prompt. Other infrastructure: - ci/tests/fm_shim_frontend/conftest.py stubs out 'stdisplay' (helper-scripts package, not in the runner's apt) and the PyQt5 Qt* submodules (a real pyqt5 install would still be needed for live use, but isn't required for property-testing the URI validator function in isolation). - agents/fuzzing.md documents the layout and the local-run invocation, mirroring helper-scripts' agents/fuzzing.md. - AGENTS.md gains a Component Notes pointer to the new doc.

Process-level fuzzing complementing the in-process Hypothesis suite already covering fm_shim_frontend. What gets exercised: - D-Bus marshaling glue (libdbus-1 path). - Method dispatch in main()'s message loop. - sd_notify error path under transient session bus. - Signal handler interactions. - Resource lifecycle across method calls (fd leaks etc). What's NOT exercised here: - The frontend prompt logic (covered by Hypothesis tests). - The in-process parser (libFuzzer harness deferred per AGENTS.md fuzzing notes). Workflow body in ci/dfuzzer-run.sh (R-100): 1. compile-fm-shim-backend -> tmpdir binary 2. Write XDG-local D-Bus session service file pointing at the tmpdir binary so dbus auto-activates it on first method call. 3. dbus-run-session boots a transient session bus and runs dfuzzer --bus session --name org.freedesktop.FileManager1 --max-time $DFUZZER_SECONDS --verbose. Trigger: workflow_dispatch only initially (mirrors helper- scripts/fuzz.yml). Once a green-baseline run lands, the commented-out path-filtered pull_request trigger can be enabled. Default per-method budget 60s; overridable via workflow_dispatch input. Note: dfuzzer is in the Ubuntu universe pocket (apt-installable on ubuntu-latest by default).

The previous '--name' / '--bus session' invocation produced 'unrecognized option' and dfuzzer exited 1 before fuzzing anything. 2. dfuzzer has NO time-bounded flag - only iteration counts. Wrap with shell 'timeout --preserve-status' to enforce a per-job time budget. Exit code 124 (budget reached) is treated as success since hitting the budget means we got the configured amount of fuzzing. 3. Removed '--bus session' - dfuzzer auto-detects the bus from DBUS_SESSION_BUS_ADDRESS (set by dbus-run-session above), which is what we want. The 'set -o errexit' inside the inner bash -c was also dropped because we now want the wrapper script (not errexit) to drive the exit-code interpretation; dfuzzer's real exit code reaches us via 'rc=$?' and is mapped to a friendly outcome string. --- ci/dfuzzer-run.sh | 57 ++++++++++++++++++++++++++++++++++++----------- 1 file changed, 44 insertions(+), 13 deletions(-) diff --git a/ci/dfuzzer-run.sh b/ci/dfuzzer-run.sh index 04f16554..f478c088 100755 --- a/ci/dfuzzer-run.sh +++ b/ci/dfuzzer-run.sh @@ -69,23 +69,54 @@ cat -- "${service_dir}/org.freedesktop.FileManager1.service" printf '%s\n' "::group::dfuzzer (org.freedesktop.FileManager1, ${dfuzzer_seconds}s)" ## dbus-run-session boots a transient session bus and runs the ## inner shell with DBUS_SESSION_BUS_ADDRESS pointing at it. -## dfuzzer activates the service via name resolution. +## dfuzzer reads that env var to talk to the session bus, then +## activates the service via name resolution against our +## XDG-local .service file. ## -## --max-time bounds the per-method fuzz duration so the workflow -## doesn't run unbounded. -v emits per-method progress so a CI -## maintainer reading the log can see which interface / method -## was being exercised when a crash occurred. +## dfuzzer flag conventions (verified against v2.6 src/dfuzzer.c +## getopt table): +## -n / --bus bus name to fuzz (e.g. org.freedesktop.X) +## NB: misnamed long flag - 'bus' here means +## the service-bus-NAME, not the bus type. +## -v / --verbose per-method progress output. +## Note: dfuzzer has NO time-bounded flag.

Switched approach: 1. Inside dbus-run-session, start fm-shim-backend in the background. It registers the org.freedesktop.FileManager1 well-known name on the session bus and enters its dispatch loop. 2. sleep 1 + kill -0 check to surface 'backend died during startup' before dfuzzer's misleading 'name not found' error. 3. Run dfuzzer against the now-registered name. 4. EXIT-trap kills the backend at the end. Also restructured to avoid multi-level shell quoting: the inner script lives in a tempfile and gets the binary path + seconds budget as positional args. Easier to read; bug-class found while debugging. dfuzzer flag now '-I 50' (50 iterations per method, default per- method coverage on the small FileManager1 surface).

Symptoms before this fix: - 'busctl introspect --user org.freedesktop.FileManager1 /org/freedesktop/FileManager1' fails with 'Unknown interface'. - 'd-feet' / 'qdbusviewer' don't enumerate the service's methods. - dfuzzer exits 1 with no usable output (can't introspect -> doesn't know what to fuzz). Fix is conventional: implement Introspect to return a static XML description of the FileManager1 surface plus the standard Introspectable interface itself. Argument signatures ('as' for the URI list, 's' for the startup ID) match the freedesktop.org file-manager-interface spec. Static string + one extra branch in dispatch; no runtime cost. Discovered by: ci/dfuzzer-run.sh first integration run on master 6ed21ea (2026-05-08). With this patch dfuzzer can introspect, enumerate the three methods (ShowFolders, ShowItems, ShowItemProperties), and proceed to fuzz them. --- .../fm-shim-backend.c#security-misc-shared | 90 +++++++++++++++++-- 1 file changed, 85 insertions(+), 5 deletions(-) diff --git a/usr/src/security-misc/fm-shim-backend.c#security-misc-shared b/usr/src/security-misc/fm-shim-backend.c#security-misc-shared index e62c5762..77152ea5 100644 --- a/usr/src/security-misc/fm-shim-backend.c#security-misc-shared +++ b/usr/src/security-misc/fm-shim-backend.c#security-misc-shared @@ -233,6 +233,70 @@ dbus_cleanup: } } +/* + * Introspection XML for the org.freedesktop.FileManager1 interface + * we implement, plus the standard org.freedesktop.DBus.Introspectable + * interface itself.

Exit status: 1' - which is dfuzzer's normal idle output, not the actual error), add three probes that surface the real state of the world: 1. fm-shim-backend stdout/stderr captured to a tmpdir log file and dumped via ::group::. Without a tty its output is block- buffered and gets lost when the kill-on-EXIT trap fires; redirecting to a file flushes on close. 2. NameHasOwner poll loop (up to 5 attempts at 1s each) that confirms the well-known name is registered before dfuzzer tries to talk to it. Fails fast and surfaces the backend's stdout if the backend dies during startup. 3. 'busctl --user introspect' before dfuzzer to verify the Introspectable wiring (the just-added handle_introspect() in fm-shim-backend.c). If busctl can't introspect, dfuzzer won't be able to either - and we'll see exactly where the chain breaks.

Exit code 124 (budget reached) is + treated as success since hitting the budget means we got + the configured amount of fuzzing. + + 3. Removed '--bus session' - dfuzzer auto-detects the bus from + DBUS_SESSION_BUS_ADDRESS (set by dbus-run-session above), + which is what we want. + + The 'set -o errexit' inside the inner bash -c was also dropped + because we now want the wrapper script (not errexit) to drive + the exit-code interpretation; dfuzzer's real exit code reaches + us via 'rc=$?' and is mapped to a friendly outcome string. + +commit 19f88613f2d0b881614615daf4e24e99025e0b34 +Author: Claude +Date: Fri May 8 13:56:47 2026 +0000 + + dfuzzer.yml: fix binary path (build/dfuzzer not build/src/dfuzzer) + +commit e54cf73996fec5a7737ee19bf2701a5385054d87 +Author: Claude +Date: Fri May 8 13:55:13 2026 +0000 + + dfuzzer.yml: bump tag pin v1.7 -> v2.6 (real latest) + +commit 487a08d1caa42bed0f3b821f2bacfcb09fc990f6 +Author: Claude +Date: Fri May 8 13:53:27 2026 +0000 + + dfuzzer.yml: build dfuzzer from source + + dfuzzer is not in the Ubuntu 24.04 (noble) archive (verified + via packages.ubuntu.com - 'No such package').

Behavior change: bandit now scans the whole repo via shebang discovery (including any Python outside `usr/lib/python3/dist-packages/fm_shim_frontend`). If new false positives surface, suppress per-line with `# nosec`. ci/codeql-prepare.sh remains in the repo - it's still used by codeql-python and codeql-cpp jobs (per .github/dm-consumer.yml). --- .github/workflows/bandit.yml | 37 ----------------------- .github/workflows/consumer-bandit.yml | 42 +++++++++++++++++++++++++++ 2 files changed, 42 insertions(+), 37 deletions(-) delete mode 100644 .github/workflows/bandit.yml create mode 100644 .github/workflows/consumer-bandit.yml diff --git a/.github/workflows/bandit.yml b/.github/workflows/bandit.yml deleted file mode 100644 index 61e889d2..00000000 --- a/.github/workflows/bandit.yml +++ /dev/null @@ -1,37 +0,0 @@ ---- -## Copyright (C) 2026 - 2026 ENCRYPTED SUPPORT LLC -## See the file COPYING for copying conditions. - -## AI-Assisted - -## Consumer wrapper.

Three problems: 1. Same `tar: partial/: Permission denied` cache-save warning as the developer-meta-files reusables (apt\'s _apt:root 0700 partial/ subdir is unreadable by the runner; chown doesn\'t help because apt-get install recreates partial/ 0700 every run). 2. `restore-keys:` violates agents/github-actions.md G-A-007 ("no broad restore-keys, no pull_request_target + cache" - cache-poisoning risk). The cache-key already includes hashFiles() so a config change naturally invalidates; restore-keys would defeat that. 3. Duplicated `Prepare apt cache directory` + `Cache apt packages` YAML across two workflows. Fix: replace those steps with one composite-action call: - uses: org-ai-assisted/developer-meta-files/.github/actions/apt-install-with-cache@master with: packages: \'\' cache-key: ${{ runner.os }}-apt--${{ hashFiles(...) }} The composite action caches `~/.apt-deb-cache` (runner-owned, no system-dir permission gymnastics) and sudo-copies .debs in/out of /var/cache/apt/archives around apt-get install. apt\'s normal permission model is preserved. local-dbus-fuzz.yml additionally: - ci/dfuzzer-build.sh is refactored to drop its `Phase 1` apt install. The package list moves into the workflow (passed to the composite action), where it lives alongside the cache key that invalidates on changes. dfuzzer-build.sh now only does the `Phase 2` build from upstream source. Depends on org-ai-assisted/developer-meta-files#92 (which adds the composite action). This PR\'s CI will pass once #92 merges. --- .github/workflows/local-dbus-fuzz.yml | 26 +++++++--------- .github/workflows/local-python-lint.yml | 29 +++++------------- ci/dfuzzer-build.sh | 40 +++++++++++-------------- 3 files changed, 34 insertions(+), 61 deletions(-) diff --git a/.github/workflows/local-dbus-fuzz.yml b/.github/workflows/local-dbus-fuzz.yml index 4f626a5c..26295f7b 100644 --- a/.github/workflows/local-dbus-fuzz.yml +++ b/.github/workflows/local-dbus-fuzz.yml @@ -68,24 +68,18 @@ jobs: with: persist-credentials: false - - name: Prepare apt cache directory - run: | - sudo mkdir -p /var/cache/apt/archives - sudo chown -R "$(id -u):$(id -g)" /var/cache/apt/archives - - - name: Cache apt packages - uses: actions/cache@27d5ce7f107fe9357f9df03efb73ab90386fccae # v5.0.5 + ## apt deps for dfuzzer-build.sh (build + runtime + fm-shim + ## backend compile).

This commit does that: - local-python-lint.yml switches from apt-install-with-cache to the developer-meta-files install-deps composite action, which installs apt deps + genmkfile + helper-scripts (the latter provides stdisplay). PyQt5 was already in the apt list (python3-pyqt5 + python3-pyqt5.sip), so the real Qt classes are available now too. - conftest.py is deleted. Property tests now run against the production modules end-to-end (the QApplication() call only fires inside fm_shim_frontend's main(), which the test never invokes - it imports get_path_list_from_uris directly). - local-dbus-fuzz.yml also switches to install-deps for consistency (same composite-action pattern); ci/dfuzzer-build.sh header comment updated to point at install-deps instead of apt-install-with-cache. Same shape as the recent msgcollector simplification (PR #21): let install-deps handle apt + genmkfile + helper-scripts in one step. --- .github/workflows/local-dbus-fuzz.yml | 14 ++--- .github/workflows/local-python-lint.yml | 19 +++--- ci/dfuzzer-build.sh | 7 +-- ci/tests/fm_shim_frontend/conftest.py | 77 ------------------------- 4 files changed, 22 insertions(+), 95 deletions(-) delete mode 100644 ci/tests/fm_shim_frontend/conftest.py diff --git a/.github/workflows/local-dbus-fuzz.yml b/.github/workflows/local-dbus-fuzz.yml index 26295f7b..c496432e 100644 --- a/.github/workflows/local-dbus-fuzz.yml +++ b/.github/workflows/local-dbus-fuzz.yml @@ -68,14 +68,14 @@ jobs: with: persist-credentials: false - ## apt deps for dfuzzer-build.sh (build + runtime + fm-shim - ## backend compile).

Where `[ -w ]` passed but shred failed anyway, shred ran as a bare command and tripped the ERR trap that pre.bsh installs, aborting with a "## Please report this bug!" banner and exit 1. Branch on shred's exit status instead of `[ -w ]`, which does not predict removability. Unlinking depends on write permission on the parent directory rather than on the file itself, and an append-only file passes the test yet cannot be unlinked at all. For a full-capability root process the check is also true on a mode 444 file, so it only ever failed on read-only file systems and on files carrying the immutable attribute. Clear the immutable and append-only attributes before each attempt. Per review, a System.map should never be immutable and `chattr +i` would possibly complicate kernel package removal; append-only is cleared on the same grounds, since it blocks removal without affecting `[ -w ]`. Report the files that remain once at the end, under a single wiki link rather than repeating it on every line, and withhold "Done. Success." when anything failed. A file reachable under two names, such as /lib/modules//build and the source symlink beside it, is listed under each, since both matched and both failed. Iterate an array rather than word-splitting a string with IFS, which a /etc/remove-system.map_pre.d drop-in can set; under `IFS=:` the globs matched nothing, so the script deleted nothing and still exited 0. The removal loop no longer exits early on failure and the script ends in an explicit `exit 0`; a non-zero status would fail the kernel package's postinst hook and the oneshot unit on every boot. --- .../remove-system.map#security-misc-shared | 49 ++++++++++++------- 1 file changed, 31 insertions(+), 18 deletions(-) diff --git a/usr/libexec/security-misc/remove-system.map#security-misc-shared b/usr/libexec/security-misc/remove-system.map#security-misc-shared index 5b75f6de..573907bf 100755 --- a/usr/libexec/security-misc/remove-system.map#security-misc-shared +++ b/usr/libexec/security-misc/remove-system.map#security-misc-shared @@ -12,31 +12,44 @@ fi shopt -s nullglob -system_map_location="/boot/System.map* /usr/src/*/System.map* /lib/modules/*/*/System.map* /System.map*" +system_map_list=( /boot/System.map* /usr/src/*/System.map* /lib/modules/*/*/System.map* /System.map* ) -counter=0 -for filename in ${system_map_location} ; do - counter=$(( counter + 1 )) -done - -if [ "$counter" -ge "1" ]; then +if (( ${#system_map_list[@]} > 0 )); then echo "INFO: Deleting system.map files..." fi +failed_list=() + ## Removes the System.map files as they are only used for debugging or malware. -for filename in ${system_map_location} ; do - if [ -f "${filename}" ]; then - if [ -w "${filename}" ]; then - ## 'shred' with '--verbose' is too chatty.

An unknown target is stored without validation and simply never matches, so the --remove was inert in both calls: the prerm call was an effective no-op, while the postrm call still performed a plain reconciliation. The prerm early-disable was therefore dead. On removal /etc/pam.d/common-* kept referencing helper scripts under /usr/libexec/security-misc/ that dpkg then deleted; block-unsafe-logins is a Priority 1100 'requisite' entry, so a dangling reference fails all authentication until postrm's reconciliation regenerates common-* -- permanently, if postrm fails before that point. prerm now passes the eight profile filenames explicitly. postrm drops the ineffective '--remove ' for a plain reconciliation and guards it with 'command -v': Debian Policy 7.2 gives no guarantee that dependencies are available when postrm runs and requires postrm to gracefully skip such actions, and an absent pam-auth-update would abort the script under 'set -e'. prerm stays unguarded: Policy names Depends (here libpam-runtime) as the mechanism prerm scripts rely on, dependencies there normally being at least unpacked. One consequence of a '--remove' that now takes effect: it also drops the eight names from /var/lib/pam/seen. If a removal is aborted, postinst's 'pam-auth-update --package' re-enables the seven 'Default: yes' profiles among them, including any of them an administrator had deliberately disabled (other packages' profiles remain in seen and are unaffected), while console-lockdown-security-misc ('Default: no') stays off until an administrator re-enables it -- reinstalling does not restore it, since preinst's enable is behind a do_once stamp. Both are new relative to the previous inert behavior. --- debian/security-misc-shared.postrm | 6 +++++- debian/security-misc-shared.prerm | 15 ++++++++++++++- 2 files changed, 19 insertions(+), 2 deletions(-) diff --git a/debian/security-misc-shared.postrm b/debian/security-misc-shared.postrm index 13dc5884..3312a215 100755 --- a/debian/security-misc-shared.postrm +++ b/debian/security-misc-shared.postrm @@ -16,7 +16,11 @@ true " " ## https://forums.whonix.org/t/is-security-misc-suitable-for-hardening-bridges-and-relays/8299/11 -pam-auth-update --package --remove "$DPKG_MAINTSCRIPT_PACKAGE" +## Debian Policy 7.2: there is no guarantee that dependencies (here +## libpam-runtime) are available when postrm runs; skip gracefully then. +if command -v pam-auth-update >/dev/null 2>&1; then + pam-auth-update --package +fi rm -f /etc/sysctl.d/30_security-misc_aslr-mmap.conf diff --git a/debian/security-misc-shared.prerm b/debian/security-misc-shared.prerm index 1c4cd871..d2b6b270 100755 --- a/debian/security-misc-shared.prerm +++ b/debian/security-misc-shared.prerm @@ -16,7 +16,20 @@ true " " if [ "$1" = remove ]; then - pam-auth-update --package --remove "$DPKG_MAINTSCRIPT_PACKAGE" + ## 'pam-auth-update --remove' matches pam-config FILENAMES under + ## /usr/share/pam-configs/, not the package name.

Add the strict preamble and convert echo -> printf (R-034). The '$@' inside the message becomes '$*' deliberately. Under printf, "...$@" expands to one argument per positional parameter, so a multi-word invocation would print one word per line; '$*' joins with spaces, which is what echo did. Sandbox differential vs the pre-change scripts: all thirteen byte-identical in output and still exit 1.

Strict mode must not perturb it. PAM_SERVICE and PAM_USER come from pam_exec's environment. Read bare under nounset they abort the script with a NONZERO status, which PAM then reads as a control-flow decision. Each is now read as '${VAR:-}', which reproduces today's semantics exactly (an unset value falls through to the same branch it already took). pam-abort-on-locked-password was the sharp case.

Its loop chmods every home directory and records a state file per user, and it tolerated per-user failures: a directory it could not chmod did not stop the ones after it. Under errexit the first failure aborted the whole loop, so every remaining home directory silently stayed un-locked-down -- observed in the sandbox as 1 user processed instead of 11, and the script exiting 1 rather than 0. The two per-user operations are now explicitly best-effort, restoring the original behaviour (including that a failed chmod still records the state file -- arguably wrong, but changing it is not this pass's business). mmap-rnd-bits keeps its 'ls -1 -t /boot/config-* | head -n 1' with a reasoned SC2012 disable: kernel config filenames carry no spaces or newlines, so the parsing hazard is unreachable, and rewriting newest-file detection in a security package is risk without gain. Not touched, deliberately: the dracut modules under usr/lib/dracut/modules.d*. 'module-setup.sh' is SOURCED by dracut at initramfs build time, and remount-secure.sh is installed with 'inst_hook' and SOURCED by dracut-lib at BOOT. A strict-mode block in either runs in dracut's own shell; in the boot case that risks an unbootable system. Sandbox differential vs the pre-change scripts, comparing output AND exit code: 36 cases identical. The only two remaining deltas are 'set -x' traces of the preamble and of echo -> printf, both at unchanged exit codes.

A '# shellcheck source=' climbing out of the repo ('../../../../helper-scripts/...') therefore resolves here and not there, so shellcheck reports SC1091 and the gate fails on a commit that looked clean. The source= paths are kept -- they document where the file actually lives -- and each is paired with a 'disable=SC1091' so an absent sibling is tolerated. Same shape already used in security-misc master. Follow-on findings from the same isolated run, each with a stated reason rather than a blanket waiver: - SC2154 on systemd_notify: assigned by the sourced systemd-notify.bsh, which shellcheck can no longer follow. - SC2034 on SCRIPTNAME and output_cmd: genuinely unused. suspend-pre's output_cmd toggle is vestigial -- unlike suspend-post the script prints directly -- flagged rather than removed, since wiring it up or dropping it is a maintainer call. - SC1090 on the uwt.d conf glob: a dynamic source, which R-081 prescribes SC1090 for. Verified with a new reproducer, ~/strict-pass-tests/ci-repro.sh, which clones the repo on its own and runs the real gate there -- the condition CI actually sees. All six repos: gate exit 0.

Move the compile to a standalone build-emerg-shutdown run from postinst, which installs /usr/bin/emerg-shutdown. Compiling on-target keeps the package Architecture: all while still producing a correct per-arch static binary. - Boot-time emerg-shutdown now just copies /usr/bin/emerg-shutdown into /run (memlockd-resident), with a fallback build if the binary is absent. - dracut module ships /usr/bin/emerg-shutdown (exists right after install, fixing the require_binaries /run chicken-and-egg). - Sandbox-verified: build-emerg-shutdown produces a static ELF in /usr/bin. - Strict/style compliance on the touched scripts (waivers for the debconf maintainer script and the dracut-sourced module).

The 5-field reading is genuinely ambiguous lexically -- '/a 744 0644 root root' (spaced name) vs '/foo 0744 1000 root cap' (numeric owner). Resolve by which candidate filename exists on disk, consistent with the tool skipping nonexistent targets. Keep the no-recovery reading only when field 1 is an octal mode and only the un-recovered name exists. - Replace the lexical guard with the existence check inside the right-anchor branch; the whitelist-keyword branch is no longer gated (it was wrongly skipped for '/x 744 y matchwhitelist'). - Regression test: spaced octal-second-component case; the assertion now matches the whole first column (trailing TAB) so '/a 744' cannot substring-match the '/a 744 name' entry.

No hardening bypass -- numeric owners are rejected later against passwd names -- but a silent drop instead of a loud rejection, and the ==4 disjunct was dead code. Replace the special-case override with one existence-based loop: among the octal candidates at field_count-3 and field_count-4, pick the one whose recovered filename exists; a mode at field 1 means no-space (no recovery); fall back to the rightmost octal candidate when neither name exists. Handles the 3-field, 4-field, spaced, numeric-owner and 6-field cases uniformly. - Regression test: 6-field spaced numeric-owner case; the suite now distinguishes this fix from all three prior parser iterations.
