Merge tag 'landlock-6.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mic/linux
Pull landlock updates from Mickaël Salaün: "A Landlock ruleset can now handle two new access rights: LANDLOCK_ACCESS_NET_BIND_TCP and LANDLOCK_ACCESS_NET_CONNECT_TCP. When handled, the related actions are denied unless explicitly allowed by a Landlock network rule for a specific port. The related patch series has been reviewed for almost two years, it has evolved a lot and we now have reached a decent design, code and testing. The refactored kernel code and the new test helpers also bring the foundation to support more network protocols. Test coverage for security/landlock is 92.4% of 710 lines according to gcc/gcov-13, and it was 93.1% of 597 lines before this series. The decrease in coverage is due to code refactoring to make the ruleset management more generic (i.e. dealing with inodes and ports) that also added new WARN_ON_ONCE() checks not possible to test from user space. syzkaller has been updated accordingly [4], and such patched instance (tailored to Landlock) has been running for a month, covering all the new network-related code [5]" Link: https://lore.kernel.org/r/20231026014751.414649-1-konstantin.meskhidze@huawei.com [1] Link: https://lore.kernel.org/r/CAHC9VhS1wwgH6NNd+cJz4MYogPiRV8NyPDd1yj5SpaxeUB4UVg@mail.gmail.com [2] Link: https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next-history.git/commit/?id=c8dc5ee69d3a [3] Link: https://github.com/google/syzkaller/pull/4266 [4] Link: https://storage.googleapis.com/syzbot-assets/82e8608dec36/ci-upstream-linux-next-kasan-gce-root-ab577164.html#security%2flandlock%2fnet.c [5] * tag 'landlock-6.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mic/linux: selftests/landlock: Add tests for FS topology changes with network rules landlock: Document network support samples/landlock: Support TCP restrictions selftests/landlock: Add network tests selftests/landlock: Share enforce_ruleset() helper landlock: Support network rules with TCP bind and connect landlock: Refactor landlock_add_rule() syscall landlock: Refactor layer helpers landlock: Move and rename layer helpers landlock: Refactor merge/inherit_ruleset helpers landlock: Refactor landlock_find_rule/insert_rule helpers landlock: Allow FS topology changes for domains without such rule type landlock: Make ruleset's access masks more generic |

Merge tag 'probes-v6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull probes updates from Masami Hiramatsu:
"Cleanups:
- kprobes: Fixes typo in kprobes samples
- tracing/eprobes: Remove 'break' after return
kretprobe/fprobe performance improvements:
- lib: Introduce new `objpool`, which is a high performance lockless
object queue. This uses per-cpu ring array to allocate/release
objects from the pre-allocated object pool.
Since the index of ring array is a 32bit sequential counter, we can
retry to push/pop the object pointer from the ring without lock (as
seq-lock does)
- lib: Add an objpool test module to test the functionality and
evaluate the performance under some circumstances
- kprobes/fprobe: Improve kretprobe and rethook scalability
performance with objpool.
This improves both legacy kretprobe and fprobe exit handler (which
is based on rethook) to be scalable on SMP systems. Even with
8-threads parallel test, it shows a great scalability improvement
- Remove unneeded freelist.h which is replaced by objpool
- objpool: Add maintainers entry for the objpool
- objpool: Fix to remove unused include header lines"

samples/bpf: Allow building with custom CFLAGS/LDFLAGS
Currently, it is not possible to specify custom flags when building
samples/bpf. The flags are defined in TPROGS_CFLAGS/TPROGS_LDFLAGS
variables, however, when trying to override those from the make command,
compilation fails.
For example, when trying to build with PIE:
$ make -C samples/bpf TPROGS_CFLAGS="-fpie" TPROGS_LDFLAGS="-pie"
This is because samples/bpf/Makefile updates these variables, especially
appends include paths to TPROGS_CFLAGS and these updates are overridden
by setting the variables from the make command.
This patch introduces variables TPROGS_USER_CFLAGS/TPROGS_USER_LDFLAGS
for this purpose, which can be set from the make command and their
values are propagated to TPROGS_CFLAGS/TPROGS_LDFLAGS.

vfio/mtty: Enable migration support
The mtty driver exposes a PCI serial device to userspace and therefore makes an easy target for a sample device supporting migration. The device does not make use of DMA, therefore we can easily claim support for the migration P2P states, as well as dirty logging. This implementation also makes use of PRE_COPY support in order to provide migration stream compatibility testing, which should generally be considered good practice.

vfio/mtty: Overhaul mtty interrupt handling
The mtty driver does not currently conform to the vfio SET_IRQS uAPI.
For example, it claims to support mask and unmask of INTx, but actually
does nothing. It claims to support AUTOMASK for INTx, but doesn't. It
fails to teardown eventfds under the full semantics specified by the
SET_IRQS ioctl. It also fails to teardown eventfds when the device is
closed, leading to memory leaks. It claims to support the request IRQ,
but doesn't.
Fix all these.
A side effect of this is that QEMU will now report a warning:
vfio <uuid>: Failed to set up UNMASK eventfd signaling for interrupt \
INTX-0: VFIO_DEVICE_SET_IRQS failure: Inappropriate ioctl for device
The fact is that the unmask eventfd was never supported but quietly
failed. mtty never honored the AUTOMASK behavior, therefore there
was nothing to unmask. QEMU is verbose about the failure, but
properly falls back to userspace unmasking.

vfio: use __aligned_u64 in struct vfio_device_gfx_plane_info
The memory layout of struct vfio_device_gfx_plane_info is architecture-dependent due to a u64 field and a struct size that is not a multiple of 8 bytes: - On x86_64 the struct size is padded to a multiple of 8 bytes. - On x32 the struct size is only a multiple of 4 bytes, not 8. - Other architectures may vary. Use __aligned_u64 to make memory layout consistent. This reduces the chance of 32-bit userspace on a 64-bit kernel breakage. This patch increases the struct size on x32 but this is safe because of the struct's argsz field. The kernel may grow the struct as long as it still supports smaller argsz values from userspace (e.g. applications compiled against older kernel headers).

selftests/bpf: trace_helpers.c: Optimize kallsyms cache
Static ksyms often have problems because the number of symbols exceeds the
MAX_SYMS limit. Like changing the MAX_SYMS from 300000 to 400000 in
commit e76a014334a6("selftests/bpf: Bump and validate MAX_SYMS") solves
the problem somewhat, but it's not the perfect way.
This commit uses dynamic memory allocation, which completely solves the
problem caused by the limitation of the number of kallsyms. At the same
time, add APIs:
load_kallsyms_local()
ksym_search_local()
ksym_get_addr_local()
free_kallsyms_local()
There are used to solve the problem of selftests/bpf updating kallsyms
after attach new symbols during testmod testing.

Merge tag 'modules-6.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux
Pull modules updates from Luis Chamberlain:
"Summary of the changes worth highlighting from most interesting to
boring below:
- Christoph Hellwig's symbol_get() fix to Nvidia's efforts to
circumvent the protection he put in place in year 2020 to prevent
proprietary modules from using GPL only symbols, and also ensuring
proprietary modules which export symbols grandfather their taint.
That was done through year 2020 commit

samples/bpf: Remove the xdp_sample_pkts utility
The functionality of this utility is covered by the xdpdump utility in xdp-tools. There's a slight difference in usage as the xdpdump utility's main focus is to dump packets before or after they are processed by an existing XDP program. However, xdpdump also has the --load-xdp-program switch, which will make it attach its own program if no existing program is loaded. With this, xdp_sample_pkts usage can be converted as: xdp_sample_pkts eth0 --> xdpdump --load-xdp-program eth0 To get roughly equivalent behaviour.

samples/bpf: Remove the xdp1 and xdp2 utilities
The functionality of these utilities have been incorporated into the xdp-bench utility in xdp-tools. Equivalent functionality is: xdp1 eth0 --> xdp-bench drop -p parse-ip -l load-bytes eth0 xdp2 eth0 --> xdp-bench drop -p swap-macs eth0 Note that there's a slight difference in behaviour of those examples: the swap-macs operation of xdp-bench doesn't use the bpf_xdp_load_bytes() helper to load the packet data, whereas the xdp2 utility did so unconditionally. For the parse-ip action the use of bpf_xdp_load_bytes() can be selected by the '-l load-bytes' switch, with the difference that the xdp-bench utility will perform two separate calls to the helper, one to load the ethernet header and another to load the IP header; where the xdp1 utility only performed one call always loading 60 bytes of data.

samples/bpf: Remove the xdp_rxq_info utility
The functionality of this utility has been incorporated into the xdp-bench utility in xdp-tools, by way of the --rxq-stats argument to the 'drop', 'pass' and 'tx' commands of xdp-bench. Some examples of how to convert xdp_rxq_info invocations into equivalent xdp-bench commands: xdp_rxq_info -d eth0 --> xdp-bench pass --rxq-stats eth0 xdp_rxq_info -d eth0 -a XDP_DROP -m --> xdp-bench drop --rxq-stats -p swap-macs eth0 Signed-off-by: Toke Høiland-Jørgensen <toke@redhat.com> Link: https://lore.kernel.org/r/20230824102255.1561885-4-toke@redhat.com Signed-off-by: Alexei Starovoitov <ast@kernel.org> |
