Currently, we allocate a lbuf-sized kernel buffer and copy lbuf from userspace to that buffer. Later, we use scanf on this buffer but we don't ensure that the string is terminated inside the buffer, this can lead to OOB read when using scanf. Fix this issue by using memdup_user_nul instead.

The return-address (RA) register r14 is specified as volatile in the s390x ELF ABI [1]. Nevertheless proper CFI directives must be provided for an unwinder to restore the return address, if the RA register value is changed from its value at function entry, as it is the case.

Since commit 1b2ac5a6 ("s390/3270: use new address translation helpers") rq->buffer is passed unconditionally to virt_to_dma32().

The function __storage_key_init_range() expects the end address to be the first byte outside the range to be initialized. I.e. end - start should be the size of the area to be initialized. The current code works because __storage_key_init_range() will still loop over every page in the range, but it is slower than using sske_frame().

The recently added check to figure out if a fault happened on gmap ASCE dereferences the gmap pointer in lowcore without checking that it is not NULL. For all non-KVM processes the pointer is NULL, so that some value from lowcore will be read. With the current layouts of struct gmap and struct lowcore the read value (aka ASCE) is zero, so that this doesn't lead to any observable bug; at least currently. Fix this by adding the missing NULL pointer check.

A race condition exists in ccw_device_set_online() that can cause the online process to fail, leaving the affected device in an inconsistent state. As a result, subsequent attempts to set that device online fail with return code ENODEV. The problem occurs when a path verification request arrives after a wait for final device state completed, but before the result state is evaluated. Fix this by ensuring that the CCW-device lock is held between determining final state and checking result state. Note that since: commit 2297791c ("s390/cio: dont unregister subchannel from child-drivers") path verification requests are much more likely to occur during boot, resulting in an increased chance of this race condition occurring.

A deferred condition code 1 response indicates that I/O was not started and should be retried. The current QDIO implementation handles a cc1 response as I/O error, resulting in a failed QDIO setup. This can happen for example when a path verification request arrives at the same time as QDIO setup I/O is started. Fix this by retrying the QDIO setup I/O when a cc1 response is received. Note that since commit 2297791c ("s390/cio: dont unregister subchannel from child-drivers") commit 5ef1dc40 ("s390/cio: fix invalid -EBUSY on ccw_device_start") deferred cc1 responses are much more likely to occur.

When KCSAN and CONSTRUCTORS are enabled, one can trigger the "Unpatched return thunk in use. This should not happen!" catch-all warning. Usually, when objtool runs on the .o objects, it does generate a section .return_sites which contains all offsets in the objects to the return thunks of the functions present there. Those return thunks then get patched at runtime by the alternatives. KCSAN and CONSTRUCTORS add this to the object file's .text.startup section: ------------------- Disassembly of section .text.startup: ... 0000000000000010 <_sub_I_00099_0>: 10: f3 0f 1e fa endbr64 14: e8 00 00 00 00 call 19 <_sub_I_00099_0+0x9> 15: R_X86_64_PLT32 __tsan_init-0x4 19: e9 00 00 00 00 jmp 1e <__UNIQUE_ID___addressable_cryptd_alloc_aead349+0x6> 1a: R_X86_64_PLT32 __x86_return_thunk-0x4 ------------------- which, if it is built as a module goes through the intermediary stage of creating a <module>.mod.c file which, when translated, receives a second constructor: ------------------- Disassembly of section .text.startup: 0000000000000010 <_sub_I_00099_0>: 10: f3 0f 1e fa endbr64 14: e8 00 00 00 00 call 19 <_sub_I_00099_0+0x9> 15: R_X86_64_PLT32 __tsan_init-0x4 19: e9 00 00 00 00 jmp 1e <_sub_I_00099_0+0xe> 1a: R_X86_64_PLT32 __x86_return_thunk-0x4 ... 0000000000000030 <_sub_I_00099_0>: 30: f3 0f 1e fa endbr64 34: e8 00 00 00 00 call 39 <_sub_I_00099_0+0x9> 35: R_X86_64_PLT32 __tsan_init-0x4 39: e9 00 00 00 00 jmp 3e <__ksymtab_cryptd_alloc_ahash+0x2> 3a: R_X86_64_PLT32 __x86_return_thunk-0x4 ------------------- in the .ko file. Objtool has run already so that second constructor's return thunk cannot be added to the .return_sites section and thus the return thunk remains unpatched and the warning rightfully fires.

The -Woverride-init warn about code that may be intentional or not, but the inintentional ones tend to be real bugs, so there is a bit of disagreement on whether this warning option should be enabled by default and we have multiple settings in scripts/Makefile.extrawarn as well as individual subsystems. Older versions of clang only supported -Wno-initializer-overrides with the same meaning as gcc's -Woverride-init, though all supported versions now work with both. Because of this difference, an earlier cleanup of mine accidentally turned the clang warning off for W=1 builds and only left it on for W=2, while it's still enabled for gcc with W=1. There is also one driver that only turns the warning off for newer versions of gcc but not other compilers, and some but not all the Makefiles still use a cc-disable-warning conditional that is no longer needed with supported compilers here. Address all of the above by removing the special cases for clang and always turning the warning off unconditionally where it got in the way, using the syntax that is supported by both compilers.

Commit c33621b4 ("x86/virt/tdx: Wire up basic SEAMCALL functions") introduced a new instance of core-y instead of the standardized obj-y syntax. X86 Makefiles descend into subdirectories of arch/x86/virt inconsistently; into arch/x86/virt/ via core-y defined in arch/x86/Makefile, but into arch/x86/virt/svm/ via obj-y defined in arch/x86/Kbuild. This is problematic when you build a single object in parallel because multiple threads attempt to build the same file. $ make -j$(nproc) arch/x86/virt/vmx/tdx/seamcall.o [ snip ] AS arch/x86/virt/vmx/tdx/seamcall.o AS arch/x86/virt/vmx/tdx/seamcall.o fixdep: error opening file: arch/x86/virt/vmx/tdx/.seamcall.o.d: No such file or directory make[4]: *** [scripts/Makefile.build:362: arch/x86/virt/vmx/tdx/seamcall.o] Error 2 Use the obj-y syntax, as it works correctly.

The seccomp benchmark runs five scenarios, one calibration run with no seccomp filters enabled then four further runs each adding a filter. The calibration run times itself for 15s and then each additional run executes for the same number of times. Currently the seccomp tests, including the benchmark, run with an extended 120s timeout but this is not sufficient to robustly run the tests on a lot of platforms. Sample timings from some recent runs: Platform Run 1 Run 2 Run 3 Run 4 --------- ----- ----- ----- ----- PowerEdge R200 16.6s 16.6s 31.6s 37.4s BBB (arm) 20.4s 20.4s 54.5s Synquacer (arm64) 20.7s 23.7s 40.3s The x86 runs from the PowerEdge are quite marginal and routinely fail, for the successful run reported here the timed portions of the run are at 117.2s leaving less than 3s of margin which is frequently breached. The added overhead of adding filters on the other platforms is such that there is no prospect of their runs fitting into the 120s timeout, especially on 32 bit arm where there is no BPF JIT. While we could lower the time we calibrate for I'm also already seeing the currently completing runs reporting issues with the per filter overheads not matching expectations: Let's instead raise the timeout to 180s which is only a 50% increase on the current timeout which is itself not *too* large given that there's only two tests in this suite.
