tracing: Allow creating instances with specified system events
[ Upstream commit d23569979ca1cd139a42c410e0c7b9e6014c3b3a ] A trace instance may only need to enable specific events. As the eventfs directory of an instance currently creates all events which adds overhead, allow internal instances to be created with just the events in systems that they care about. This currently only deals with systems and not individual events, but this should bring down the overhead of creating instances for specific use cases quite bit. The trace_array_get_by_name() now has another parameter "systems". This parameter is a const string pointer of a comma/space separated list of event systems that should be created by the trace_array. (Note if the trace_array already exists, this parameter is ignored). The list of systems is saved and if a module is loaded, its events will not be added unless the system for those events also match the systems string.

bpf: Fix the xdp_adjust_tail sample prog issue
[ Upstream commit 4236f114a3ffbbfd217436c08852e94cae372f57 ]
During the xdp_adjust_tail test, probabilistic failure occurs and SKB package
is discarded by the kernel. After checking the issues by tracking SKB package,
it is identified that they were caused by checksum errors. Refer to checksum
of the arch/arm64/include/asm/checksum.h for fixing.
v2: Based on Alexei Starovoitov's suggestions, it is necessary to keep the code
implementation consistent.

bpf: Replace bpf_lpm_trie_key 0-length array with flexible array
[ Upstream commit 896880ff30866f386ebed14ab81ce1ad3710cfc4 ]
Replace deprecated 0-length array in struct bpf_lpm_trie_key with
flexible array. Found with GCC 13:
../kernel/bpf/lpm_trie.c:207:51: warning: array subscript i is outside array bounds of 'const __u8[0]' {aka 'const unsigned char[]'} [-Warray-bounds=]

And found at run-time under CONFIG_FORTIFY_SOURCE:
UBSAN: array-index-out-of-bounds in kernel/bpf/lpm_trie.c:218:49
index 0 is out of range for type '__u8 [*]'
Changing struct bpf_lpm_trie_key is difficult since has been used by
userspace. For example, in Cilium:
struct egress_gw_policy_key {
struct bpf_lpm_trie_key lpm_key;
__u32 saddr;
__u32 daddr;
};
While direct references to the "data" member haven't been found, there
are static initializers what include the final member. For example,
the "{}" here:
struct egress_gw_policy_key in_key = {
.lpm_key = { 32 + 24, {} },
.saddr = CLIENT_IP,
.daddr = EXTERNAL_SVC_IP & 0Xffffff,
};
To avoid the build time and run time warnings seen with a 0-sized
trailing array for struct bpf_lpm_trie_key, introduce a new struct
that correctly uses a flexible array for the trailing bytes,
struct bpf_lpm_trie_key_u8. As part of this, include the "header"
portion (which is just the "prefixlen" member), so it can be used
by anything building a bpf_lpr_trie_key that has trailing members that
aren't a u8 flexible array (like the self-test[1]), which is named
struct bpf_lpm_trie_key_hdr.
Unfortunately, C++ refuses to parse the __struct_group() helper, so
it is not possible to define struct bpf_lpm_trie_key_hdr directly in
struct bpf_lpm_trie_key_u8, so we must open-code the union directly.
Adjust the kernel code to use struct bpf_lpm_trie_key_u8 through-out,
and for the selftest to use struct bpf_lpm_trie_key_hdr. Add a comment
to the UAPI header directing folks to the two new options.

vfio/mtty: Overhaul mtty interrupt handling
[ Upstream commit 293fbc28818135743f54d46c418ede3e4a20a742 ]
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.

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> |

samples/bpf: Remove the xdp_redirect* utilities
These utilities have all been ported to xdp-tools as functions of the xdp-bench utility. The four different utilities in samples are incorporated as separate subcommands to xdp-bench, with most of the command line parameters left intact, except that mandatory arguments are always positional in xdp-bench. For full usage details see the --help output of each command, or the xdp-bench man page. Some examples of how to convert usage to xdp-bench are: xdp_redirect eth0 eth1 --> xdp-bench redirect eth0 eth1 xdp_redirect_map eth0 eth1 --> xdp-bench redirect-map eth0 eth1 xdp_redirect_map_multi eth0 eth1 eth2 eth3 --> xdp-bench redirect-multi eth0 eth1 eth2 eth3 xdp_redirect_cpu -d eth0 -c 0 -c 1 --> xdp-bench redirect-cpu -c 0 -c 1 eth0 xdp_redirect_cpu -d eth0 -c 0 -c 1 -r eth1 --> xdp-bench redirect-cpu -c 0 -c 1 eth0 -r redirect -D eth1 Signed-off-by: Toke Høiland-Jørgensen <toke@redhat.com> Link: https://lore.kernel.org/r/20230824102255.1561885-3-toke@redhat.com Signed-off-by: Alexei Starovoitov <ast@kernel.org> |

This utility has been ported as-is to xdp-tools as 'xdp-monitor'.

samples: ftrace: Replace bti assembly with hint for older compiler
When cross-building the arm64 kernel with allmodconfig using GCC 9.4,
the following error occurs on multiple files under samples/ftrace/:
/tmp/ccPC1ODs.s: Assembler messages:
/tmp/ccPC1ODs.s:8: Error: selected processor does not support `bti c'
Fix this issue by replacing `bti c` with `hint 34`, which is compatible
for the older compiler.

samples/bpf: simplify spintest with kprobe.multi
With the introduction of kprobe.multi, it is now possible to attach
multiple kprobes to a single BPF program without the need for multiple
definitions. Additionally, this method supports wildcard-based
matching, allowing for further simplification of BPF programs. In here,
an asterisk (*) wildcard is used to map to all symbols relevant to
spin_{lock|unlock}.
Furthermore, since kprobe.multi handles symbol matching, this commit
eliminates the need for the previous logic of reading the ksym table to
verify the existence of symbols.
