Linus Torvalds 976b029d06 A single fix for the generic entry code: ... THe trace_sys_enter() tracepoint can modify the syscall number via kprobes or BPF in pt_regs, but that requires that the syscall number is re-evaluted from pt_regs after the tracepoint. A seccomp fix in that area removed the re-evaluation so the change does not take effect as the code just uses the locally cached number. Restore the original behaviour by re-evaluating the syscall number after the tracepoint. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmX/LJoTHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYodkJEACFbJqxdlpoWvc8lpYd0htqP+EyN6li quMk+acE8IOtiqOetphOrmKGzBYdtpNu+7uWVeRTyCarm2Gb5lX1GnIMwyEK8R25 R+fVbPaECldSUKypAbTze2RpJl/vp2jeKhCpOn3A5MpITd0vV9SEs+9hecBz3ucZ CXB4vPR7n8VxHX5ArbHqe05fF5TnSZ4CnpeWONQghGsEaSJ87XrljVfC/fxmb7mZ yB2KAIKeYqslvoFoIWSAJk6xvwcGC08vY8mxkM6n61yXmAZ33BWvpnafGHsstF/V gT9Kmvs7F6Tn6V5j0SUuC4/nUO/dtEDhvra793OSvR/rB3+AmZfECPQaDNIJqNaG 0pG558E+hrnpV/YWGzRYJCtqUgtTS0kV5JJY9ffoJRQB3Nb7GCeyykDcs823Yt7j A5o3JUQU0kW4X08hGFMU6DSFppxp9nS0eXDoKMlVRmDB8l30bLK+tMPMaID6yGse 0UafVMWRhtM85mqNVZIZKTsRuONvT+8PV2UH5cNryGmjjbykLmjSLFRvXBmk2Jl+ uhcc0QaApQleA/H/fSNoyPFOPCqvDBEo4xM9e3ypc8TflOQegZfpzrjAITHzv9hY r4ci8faKXTR7jY70a6TiEgcGYYLYDmyvOL0I+TwYA9qHB7tEaJMF6YfU8UDsM9K2 Gb4l6n8fNQubTg== =iW0L -----END PGP SIGNATURE----- Merge tag 'core-entry-2024-03-23' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull core entry fix from Thomas Gleixner: "A single fix for the generic entry code: The trace_sys_enter() tracepoint can modify the syscall number via kprobes or BPF in pt_regs, but that requires that the syscall number is re-evaluted from pt_regs after the tracepoint.
