[PATCH v2] doc: kselftest: update for clarity on running kselftests in CI rings

by Shuah Khan

Update to add clarity and recommendations on running newer kselftests on older kernels vs. matching the kernel and kselftest revisions. The recommendation is "Match kernel revision and kselftest."

This patchset is a revival of Al Viro's old AT_NO_JUMPS[1,2] patchset (which was a variant of David Drysdale's O_BENEATH patchset[3] which was a spin-off of the Capsicum project[4]) with a few additions and changes made based on the previous discussion within [5] as well as others I felt were useful. In line with the conclusions of the original discussion of AT_NO_JUMPS, the flag has been split up into separate flags. However, instead of being an openat(2) flag it is provided through a new syscall openat2(2) which provides several other improvements to the openat(2) interface (see the patch description for more details). The following new LOOKUP_* flags are added: * LOOKUP_NO_XDEV blocks all mountpoint crossings (upwards, downwards, or through absolute links). Absolute pathnames alone in openat(2) do not trigger this. * LOOKUP_NO_MAGICLINKS blocks resolution through /proc/$pid/fd-style links. This is done by blocking the usage of nd_jump_link() during resolution in a filesystem. The term "magic-links" is used to match with the only reference to these links in Documentation/, but I'm happy to change the name. It should be noted that this is different to the scope of ~LOOKUP_FOLLOW in that it applies to all path components. However, you can do openat2(NO_FOLLOW|NO_MAGICLINKS) on a magic-link and it will *not* fail (assuming that no parent component was a magic-link), and you will have an fd for the magic-link. * LOOKUP_BENEATH disallows escapes to outside the starting dirfd's tree, using techniques such as ".." or absolute links. Absolute paths in openat(2) are also disallowed. Conceptually this flag is to ensure you "stay below" a certain point in the filesystem tree -- but this requires some additional to protect against various races that would allow escape using "..". Currently LOOKUP_BENEATH implies LOOKUP_NO_MAGICLINKS, because it can trivially beam you around the filesystem (breaking the protection). In future, there might be similar safety checks done as in LOOKUP_IN_ROOT, but that requires more discussion. In addition, two new flags are added that expand on the above ideas: * LOOKUP_NO_SYMLINKS does what it says on the tin. No symlink resolution is allowed at all, including magic-links. Just as with LOOKUP_NO_MAGICLINKS this can still be used with NOFOLLOW to open an fd for the symlink as long as no parent path had a symlink component. * LOOKUP_IN_ROOT is an extension of LOOKUP_BENEATH that, rather than blocking attempts to move past the root, forces all such movements to be scoped to the starting point. This provides chroot(2)-like protection but without the cost of a chroot(2) for each filesystem operation, as well as being safe against race attacks that chroot(2) is not. If a race is detected (as with LOOKUP_BENEATH) then an error is generated, and similar to LOOKUP_BENEATH it is not permitted to cross magic-links with LOOKUP_IN_ROOT. The primary need for this is from container runtimes, which currently need to do symlink scoping in userspace[6] when opening paths in a potentially malicious container. There is a long list of CVEs that could have bene mitigated by having RESOLVE_THIS_ROOT (such as CVE-2017-1002101, CVE-2017-1002102, CVE-2018-15664, and CVE-2019-5736, just to name a few). And further, several semantics of file descriptor "re-opening" are now changed to prevent attacks like CVE-2019-5736 by restricting how magic-links can be resolved (based on their mode). This required some other changes to the semantics of the modes of O_PATH file descriptor's associated /proc/self/fd magic-links. openat2(2) has the ability to further restrict re-opening of its own O_PATH fds, so that users can make even better use of this feature. Finally, O_EMPTYPATH was added so that users can do /proc/self/fd-style re-opening without depending on procfs. The new restricted semantics for magic-links are applied here too. In order to make all of the above more usable, I'm working on libpathrs[7] which is a C-friendly library for safe path resolution. It features a userspace-emulated backend if the kernel doesn't support openat2(2). Hopefully we can get userspace to switch to using it, and thus get openat2(2) support for free once it's ready.

[PATCH] KVM: selftests: Add a test for the KVM_S390_MEM_OP ioctl

by Thomas Huth

Check that we can write and read the guest memory with this s390x ioctl, and that some error cases are handled correctly.

[PATCH v1] sefltest/ima: support appended signatures (modsig)

by Mimi Zohar

In addition to the PE/COFF and IMA xattr signatures, the kexec kernel image can be signed with an appended signature, using the same scripts/sign-file tool that is used to sign kernel modules. This patch adds support for detecting a kernel image signed with an appended signature and updates the existing test messages appropriately.

[PATCH v1] printk: add dummy vprintk_emit for when CONFIG_PRINTK=n

by Brendan Higgins

Previously vprintk_emit was only defined when CONFIG_PRINTK=y, this caused a build failure in kunit/test.c when CONFIG_PRINTK was not set. Add a no-op dummy so that callers don't have to ifdef around this. Note: It has been suggested that this go in through the kselftest tree along with the KUnit patches, because KUnit depends on this. See the second link for the discussion on this.

[PATCH v1] kunit: fix failure to build without printk

by Brendan Higgins

Previously KUnit assumed that printk would always be present, which is not a valid assumption to make. Fix that by ifdefing out functions which directly depend on printk core functions similar to what dev_printk does. Reported-by: Randy Dunlap <rdunlap(a)infradead.org> Link: https://lore.kernel.org/linux-kselftest/0352fae9-564f-4a97-715a-fabe016259d… Cc: Stephen Rothwell <sfr(a)canb.auug.org.au> Signed-off-by: Brendan Higgins <brendanhiggins(a)google.com> --- include/kunit/test.h | 7 +++++++ kunit/test.c | 41 ++++++++++++++++++++++++----------------- 2 files changed, 31 insertions(+), 17 deletions(-) diff --git a/include/kunit/test.h b/include/kunit/test.h index 8b7eb03d4971..339af5f95c4a 100644 --- a/include/kunit/test.h +++ b/include/kunit/test.h @@ -339,9 +339,16 @@ static inline void *kunit_kzalloc(struct kunit *test, size_t size, gfp_t gfp) void kunit_cleanup(struct kunit *test); +#ifdef CONFIG_PRINTK void __printf(3, 4) kunit_printk(const char *level, const struct kunit *test, const char *fmt, ...); +#else +static inline void __printf(3, 4) kunit_printk(const char *level, + const struct kunit *test, + const char *fmt, ...) +{} +#endif /** * kunit_info() - Prints an INFO level message associated with @test. diff --git a/kunit/test.c b/kunit/test.c index b2ca9b94c353..0aa1caf07a6b 100644 --- a/kunit/test.c +++ b/kunit/test.c @@ -16,6 +16,7 @@ static void kunit_set_failure(struct kunit *test) WRITE_ONCE(test->success, false); } +#ifdef CONFIG_PRINTK static int kunit_vprintk_emit(int level, const char *fmt, va_list args) { return vprintk_emit(0, level, NULL, 0, fmt, args); @@ -40,6 +41,29 @@ static void kunit_vprintk(const struct kunit *test, kunit_printk_emit(level[1] - '0', "\t# %s: %pV", test->name, vaf); } +void kunit_printk(const char *level, + const struct kunit *test, + const char *fmt, ...) +{ + struct va_format vaf; + va_list args; + + va_start(args, fmt); + + vaf.fmt = fmt; + vaf.va = &args; + + kunit_vprintk(test, level, &vaf); + + va_end(args); +} +#else /* CONFIG_PRINTK */ +static inline int kunit_printk_emit(int level, const char *fmt, ...) +{ + return 0; +} +#endif /* CONFIG_PRINTK */ + static void kunit_print_tap_version(void) { static bool kunit_has_printed_tap_version; @@ -504,20 +528,3 @@ void kunit_cleanup(struct kunit *test) kunit_resource_free(test, resource); } } - -void kunit_printk(const char *level, - const struct kunit *test, - const char *fmt, ...) -{ - struct va_format vaf; - va_list args; - - va_start(args, fmt); - - vaf.fmt = fmt; - vaf.va = &args; - - kunit_vprintk(test, level, &vaf); - - va_end(args); -} -- 2.23.0.187.g17f5b7556c-goog
