I'd describe this one as a good old CPU bug where the behavior is _obviously_ wrong, but since it just results in bad predictions it wasn't wrong enough to notice. Well, the researchers noticed and also realized that thus bug undermined a bunch of existing indirect branch mitigations. Thus the unusually wide impact on this one. Details: ITS is a bug in some Intel CPUs that affects indirect branches including RETs in the first half of a cacheline. Due to ITS such branches may get wrongly predicted to a target of (direct or indirect) branch that is located in the second half of a cacheline. Researchers at VUSec found this behavior and reported to Intel. Affected processors: - Cascade Lake, Cooper Lake, Whiskey Lake V, Coffee Lake R, Comet Lake, Ice Lake, Tiger Lake and Rocket Lake. Scope of impact: - Guest/host isolation: When eIBRS is used for guest/host isolation, the indirect branches in the VMM may still be predicted with targets corresponding to direct branches in the guest. - Intra-mode using cBPF: cBPF can be used to poison the branch history to exploit ITS. Realigning the indirect branches and RETs mitigates this attack vector. - User/kernel: With eIBRS enabled user/kernel isolation is *not* impacted by ITS. - Indirect Branch Prediction Barrier (IBPB): Due to this bug indirect branches may be predicted with targets corresponding to direct branches which were executed prior to IBPB. This will be fixed in the microcode. Mitigation: As indirect branches in the first half of cacheline are affected, the mitigation is to replace those indirect branches with a call to thunk that is aligned to the second half of the cacheline. RETs that take prediction from RSB are not affected, but they may be affected by RSB-underflow condition. So, RETs in the first half of cacheline are also patched to a return thunk that executes the RET aligned to second half of cacheline" * tag 'its-for-linus-20250509' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: selftest/x86/bugs: Add selftests for ITS x86/its: FineIBT-paranoid vs ITS x86/its: Use dynamic thunks for indirect branches x86/ibt: Keep IBT disabled during alternative patching mm/execmem: Unify early execmem_cache behaviour x86/its: Align RETs in BHB clear sequence to avoid thunking x86/its: Add support for RSB stuffing mitigation x86/its: Add "vmexit" option to skip mitigation on some CPUs x86/its: Enable Indirect Target Selection mitigation x86/its: Add support for ITS-safe return thunk x86/its: Add support for ITS-safe indirect thunk x86/its: Enumerate Indirect Target Selection (ITS) bug Documentation: x86/bugs/its: Add ITS documentation

And the root cause is that it has too much free memory than what the test supports. The test case tries to allocate 100000 huge pages, which is about 200 GB for that x86 server, and when it succeeds, it expects it's large than 1/3 of 80% of the free memory in system. This logic only works for platform with 750 GB ( 200 / (1/3) / 80% ) or less free memory, and may raise false alarm for others. Fix it by changing the fixed page number to self-adjustable number according to the real number of free memory.

Add selftest to check that all gre, ip6gre, gretap and ip6gretap get an IPv6 link-link local address in accordance with the net.ipv6.conf.<dev>.addr_gen_mode sysctl. Note: This patch was originally applied as commit 6f50175ccad4 ("selftests: Add IPv6 link-local address generation tests for GRE devices."). However, it was then reverted by commit 355d940f4d5a ("Revert "selftests: Add IPv6 link-local address generation tests for GRE devices."") because the commit it depended on was going to be reverted. Now that the situation is resolved, we can add this selftest again (no changes since original patch, appart from context update in tools/testing/selftests/net/Makefile).

This causes the generated uapi path to resolve to '/../arch' which results in a permissions error: mkdir: cannot create directory '/../arch': Permission denied Fix it by removing the preceding '/..' which means that it gets generated either in the tools/lib/perf part of the tree or the OUTPUT folder. Some other rules that rely on OUTPUT further refine this conditionally depending on whether it's an in-source or out-of-source build, but I don't think we need the extra complexity here. And this rule is slightly different to others because the header is needed by both libperf and Perf. This is further complicated by the fact that Perf always passes O=... to libperf even for in source builds, meaning that OUTPUT isn't set consistently between projects. Because we're no longer going one level up to try to generate the file in the tools/ folder, Perf's include rule needs to descend into libperf. Also fix the clean rule while we're here.

Therefore we must also generate the syscall header for arm64 before building Perf. Add it as a dependency to libperf which uses one syscall number. Perf uses more, but as libperf is a dependency of Perf it will be generated for both. Future platforms that need this will have to add their own syscall-y targets in libperf manually. Unfortunately the arch specific files that do this (e.g. arch/arm64/include/asm/Kbuild) can't easily be imported into the Perf build. But Perf only needs a subset of the generated files anyway, so redefining them is probably the correct thing to do.

This is specifically intended for NICs with an offloaded data path (switchdev/DSA) and requires taprio 'flags 2'. Also, $h1 and $h2 must support hardware timestamping, and $h1 tc-etf offload, for isochron to work. Packets received by a switch while the egress port has a taprio schedule with an open gate for the traffic class must be sent right away. Packets received by the switch while the traffic class gate must be delayed until it opens. Packets received by the switch must be dropped if the gate for the traffic class never opens. Packets should pass if the maximum SDU for the traffic class allows it, and should be dropped otherwise. The schedule should auto-update itself if clock jumps take place while taprio is installed. Repeat most of the above tests after forcing two clock jumps, one backwards (in Jan 1970) and one back into the present. Symlink it from tools/testing/selftests/drivers/net/dsa, because usually DSA ports have the same MAC address, and we need STABLE_MAC_ADDRS=yes from its forwarding.config for the test to run successfully.

From man isochron-send, the window size alters the advance time (the delta between the transmission time of the packet, and its expected TX time when using SO_TXTIME or tc-taprio on the sender). In absence of the argument, isochron-send defaults to maximizing the advance time (making it equal to the cycle length). The default behavior is exactly what is problematic. An advance time that is too large will make packets intended to be out-of-band still be potentially in-band with an open gate from the schedule's previous cycle. We need to allow that advance time to be reduced. Perhaps a bit confusingly, isochron_do() has a shift_time argument currently, but that does not help here. The shift time shifts both the user space wakeup time and the expected TX time by equal amounts, it is unable of bringing them closer to one another. Set the window size properly for the Ocelot PSFP selftest as well. That used to work due to a very carefully chosen SHIFT_TIME_NS. I've re-tested that the test still works properly.

Do those bridge ports receive packets tagged with VID 0 or not, now? We don't know, there is no test. In the veth realm, this passes trivially, because veth is not VLAN filtering and this, the 8021q module lacks the instinct to add VID 0 in the first place. In the realm of VLAN filtering NICs with no switchdev offload, this should also pass, because the VLAN groups of the software bridge are consulted, where it can clearly be seen that a PVID is missing, even though the packet was initially accepted by the NIC. The test only poses a challenge for switchdev drivers, which usually have to program to hardware both VLANs from RX filtering, as well as from switchdev. Especially when a switchdev port joins a VLAN-aware bridge, it is unavoidable that it gains the NETIF_F_HW_VLAN_CTAG_FILTER feature, i.e. any 8021q uppers that the bridge port may have must also be committed to the RX filtering table of the interface. When a VLAN-tagged packet is physically received by the port, it is initially indistinguishable whether it will reach the bridge data path or the 8021q upper data path. That is rather the final step of the new tests that we introduce. We need to build context up to that stage, which means the following: - we need to test that 802.1p (VID 0) tagged traffic is received in the first place (on bridge ports with a valid PVID). This is the "8021p" test. - we need to test that the usual paths of reaching a configuration with no PVID on a bridge port are all covered and they all reach the same state.
