<bertrand.marquis@xxxxxxx> Date: Thu Oct 15 10:16:09 2020 +0100 tools/xenpmd: Fix gcc10 snprintf warning Add a check for snprintf return code and ignore the entry if we get an error. This should in fact never happen and is more a trick to make gcc happy and prevent compilation errors. This is solving the following gcc warning when compiling for arm32 host platforms with optimization activated: xenpmd.c:92:37: error: '%s' directive output may be truncated writing between 4 and 2147483645 bytes into a region of size 271 [-Werror=format-truncation=] This is also solving the following Debian bug: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=970802 Signed-off-by: Bertrand Marquis <bertrand.marquis@xxxxxxx> Acked-by: Wei Liu <wl@xxxxxxx> commit 17d192e0238d6c714e9f04593b59597b7090be38 Author: Elliott Mitchell <ehem+xen@xxxxxxx> Date: Sun Oct 11 18:11:39 2020 -0700 tools/python: Pass linker to Python build process Unexpectedly the environment variable which needs to be passed is $LDSHARED and not $LD. Otherwise Python may find the build `ld` instead of the host `ld`. Replace $(LDFLAGS) with $(SHLIB_LDFLAGS) as Python needs shared objects it can load at runtime, not executables. This uses $(CC) instead of $(LD) since Python distutils appends $CFLAGS to $LDFLAGS which breaks many linkers.

We know that we might truncate it, so the gcc warning here is wrong. Revert previous change changing buffer sizes as bigger buffers are not needed.

This occurs for S3 and CPU parking, where enough state to handle NMIs/#MCs needs to remain valid for the entire lifetime of Xen, even when we otherwise want to offline the CPU. For simplicity between various configuration, Xen always uses shadow stack mappings (Read-only + Dirty) for the guard page, irrespective of whether CET-SS is enabled. Unfortunately, the CET-SS changes in memguard_guard_stack() broke idempotency by first writing out the supervisor shadow stack tokens with plain writes, then changing the mapping to being read-only. This ordering is strictly necessary to configure the BSP, which cannot have the supervisor tokens be written with WRSS. Instead of calling memguard_guard_stack() unconditionally, call it only when actually allocating a new stack. Xenheap allocates are guaranteed to be writeable, and the net result is idempotency WRT configuring stack_base[]. Fixes: 91d26ed304f ("x86/shstk: Create shadow stacks") Reported-by: Marek Marczykowski-Górecki <marmarek@xxxxxxxxxxxxxxxxxxxxxx> Signed-off-by: Andrew Cooper <andrew.cooper3@xxxxxxxxxx> Reviewed-by: Jan Beulich <jbeulich@xxxxxxxx> commit 04182d8b795dcdabf4f3873d3f5c78b67cbc04b0 Author: Andrew Cooper <andrew.cooper3@xxxxxxxxxx> Date: Mon Oct 12 14:58:45 2020 +0100 x86/ucode/intel: Improve description for gathering the microcode revision Obtaining the microcode revision on Intel CPUs is complicated for backwards compatibility reasons. Update apply_microcode() to use a slightly more efficient CPUID invocation, now that the documentation has been updated to confirm that any CPUID instruction is fine, not just CPUID.1 Signed-off-by: Andrew Cooper <andrew.cooper3@xxxxxxxxxx> Reviewed-by: Jan Beulich <jbeulich@xxxxxxxx> commit 6065a05adf152a556fb9f11a5218c89e41b62893 Author: Andrew Cooper <andrew.cooper3@xxxxxxxxxx> Date: Mon Oct 12 13:24:31 2020 +0100 x86/traps: 'Fix' safety of read_registers() in #DF path All interrupts and exceptions pass a struct cpu_user_regs up into C. This contains the legacy vm86 fields from 32bit days, which are beyond the hardware-pushed frame. Accessing these fields is generally illegal, as they are logically out of bounds for anything other than an interrupt/exception hitting ring1/3 code. show_registers() unconditionally reads these fields, but the content is discarded before use. This is benign right now, as all parts of the stack are readable, including the guard pages. However, read_registers() in the #DF handler writes to these fields as part of preparing the state dump, and being IST, hits the adjacent stack frame. This has been broken forever, but c/s 6001660473 "x86/shstk: Rework the stack layout to support shadow stacks" repositioned the #DF stack to be adjacent to the guard page, which turns this OoB write into a fatal pagefault: (XEN) *** DOUBLE FAULT *** (XEN) ----[ Xen-4.15-unstable x86_64 debug=y Tainted: C ]---- (XEN) ----[ Xen-4.15-unstable x86_64 debug=y Tainted: C ]---- (XEN) CPU: 4 (XEN) RIP: e008:[<ffff82d04031fd4f>] traps.c#read_registers+0x29/0xc1 (XEN) RFLAGS: 0000000000050086 CONTEXT: hypervisor (d1v0) ...
