2020-03-20bpftool: Translate prog_id to its bpf prog_nameMartin KaFai Lau
The kernel struct_ops obj has kernel's func ptrs implemented by bpf_progs. The bpf prog_id is stored as the value of the func ptr for introspection purpose. In the latter patch, a struct_ops dump subcmd will be added to introspect these func ptrs. It is desired to print the actual bpf prog_name instead of only printing the prog_id. Since struct_ops is the only usecase storing prog_id in the func ptr, this patch adds a prog_id_as_func_ptr bool (default is false) to "struct btf_dumper" in order not to mis-interpret the ptr value for the other existing use-cases. While printing a func_ptr as a bpf prog_name, this patch also prefix the bpf prog_name with the ptr's func_proto. [ Note that it is the ptr's func_proto instead of the bpf prog's func_proto ] It reuses the current btf_dump_func() to obtain the ptr's func_proto string. Here is an example from the bpf_cubic.c: "void (struct sock *, u32, u32) bictcp_cong_avoid/prog_id:140" Signed-off-by: Martin KaFai Lau <kafai@fb.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Acked-by: Quentin Monnet <quentin@isovalent.com> Link: https://lore.kernel.org/bpf/20200318171650.129252-1-kafai@fb.com
2020-03-20bpftool: Print as a string for char arrayMartin KaFai Lau
A char[] is currently printed as an integer array. This patch will print it as a string when 1) The array element type is an one byte int 2) The array element type has a BTF_INT_CHAR encoding or the array element type's name is "char" 3) All characters is between (0x1f, 0x7f) and it is terminated by a null character.

2020-03-20bpftool: Print the enum's name instead of valueMartin KaFai Lau
This patch prints the enum's name if there is one found in the array of btf_enum. The commit 9eea98497951 ("bpf: fix BTF verification of enums") has details about an enum could have any power-of-2 size (up to 8 bytes). This patch also takes this chance to accommodate these non 4 byte enums.

2020-03-20tools/power/x86/intel-speed-select: Avoid duplicate Package strings for jsonSrinivas Pandruvada
For platforms where multiple packages/die, this makes "Package-" key duplicate. To make unique, add die and cpu id to key name. So "Package-0" key name will change to "Package-0-die-x:cpu-x". For example: $sudo ./intel-speed-select -f json perf-profile info Intel(R) Speed Select Technology Executing on CPU model:106[0x6a] { "package-0:die-0:cpu-0": { "perf-profile-level-0": { "cpu-count": "32", "enable-cpu-count": "32", ... ... "package-1:die-0:cpu-16": { "perf-profile-level-0": { "cpu-count": "32", "enable-cpu-count": "32", "enable-cpu-mask": "ffff0000,ffff0000", ... ... For non json format, there is no change. Here when print_package_info() is called, it will return the level to print for other information. This level is used formatting. Also in some function duplicate code was there to print package,die and CPU information. Replace all that code with a call to print_package_info().

Treat a case when mailbox/mmio command can't be handled by the kernel drivers when the module is removed or send a command which no driver can handle. In this case ENOTTY result is returned, so print error. Also when the isst_if_mmio module is removed, we can't send CLOS message messages via Mailbox on non SKX based platforms. When this module is removed, isst_platform_info.mmio_supported is set to 0. So it can't be used as a condition to send via mailbox. Here replace check for Skylake based platform to send via mailbox, other platforms can't use mailbox in lieu of MMIO.

2020-03-20tools/power/x86/intel-speed-select: Store topology informationSrinivas Pandruvada
Once the CPU is offline, the topology information (core-id, package-id, die-id) is not accessible via sysfs. So when user selects a config level more than base config 0 and offlined CPUs to match the config level, to return to base config he has to manually online CPUs before. Without this CPUs information mapping from Punit CPU numbering will lot work as it needs atlest package id for each CPU. To avoid this additional steps store the topology information in a file , which is created on the very first run after boot. Since system boots in base config and all CPUs are online, we can get information about every CPU. Once any of the APIs like get_physical_package_id(), get_physical_core_id() or get_physical_die_id() fails to read from sysfs, read from the stored mapping file. This mapping file is stored in /tmp file system. so on every boot it is recreated to make sure that any new CPUs are added to the system before boot are taken into account. But don't use the stored physical device id when trying to get information for CPU to send message in for_each_online_package_in_set(). Here use the real value from syfs and in case fails try the next CPU.

2020-03-18wireguard: noise: error out precomputed DH during handshake rather than configJason A. Donenfeld
We precompute the static-static ECDH during configuration time, in order to save an expensive computation later when receiving network packets. However, not all ECDH computations yield a contributory result. Prior, we were just not letting those peers be added to the interface. However, this creates a strange inconsistency, since it was still possible to add other weird points, like a valid public key plus a low-order point, and, like points that result in zeros, a handshake would not complete. In order to make the behavior more uniform and less surprising, simply allow all peers to be added. Then, we'll error out later when doing the crypto if there's an issue. This also adds more separation between the crypto layer and the configuration layer. Discussed-with: Mathias Hall-Andersen <mathias@hall-andersen.dk> Signed-off-by: Jason A.
