This patch is to consume the PcdCpuSmmApSyncTimeout2 to enhance the flexibility of timeout configuration. In some cases, certain processors may not be able to enter SMI, and prolonged waiting could lead to kernel soft/hard lockup. We have now defined two timeouts. The first timeout can be set to a smaller value to reduce the waiting period. Processors that are unable to enter SMI will be woken up through SMIIPL to enter SMI, followed by a second waiting period. The second timeout can be set to a larger value to prevent delays in processors entering SMI case due to the long instruction execution.

2024-06-12MdePkg/BaseLib: Let CpuDeadLoop() be breakable in debuggerRay Ni1-2/+4
Starting from certain version of Visual Studio C compiler (I don’t have the exact version. I am using VS2019), CpuDeadLoop is optimized quite well by compiler. The compiler does not generate instructions that jump out of the loop when the "Index" is non-zero. It becomes harder/impossible for developers to break out of the dead-loop in debugger. The new version of CpuDeadLoop() compares a volatile global to a volatile local. This forces 2 reads and a comparison on every loop iteration. The local variable can be set to 1 to exit the loop without modifying the global variable. Using VS2019 with max opt enabled, The dead-loop can be exit by setting Index to 1 in a debugger.

2024-06-10ArmVirtPkg/ArmVirtQemu: Implement ArmMonitorLib for QEMU specificallyArd Biesheuvel5-12/+138
Whether SMCCC calls use HVC or SMC generally depends on the exception level that the firmware executes at, but also on whether or not EL2 is implemented. This is almost always known at build time, which is why the default ArmMonitorLib used to model this as a feature PCD. However, on QEMU, things are not that simple. However, SMCCC specifies that the conduit is the same as the one used for PSCI calls (which has been retrofitted into SMCCC when it was defined). Given that QEMU provides this information via the device tree, let's use it to select the conduit, using a special ArmMonitorLib implementation. This also removes the need to set the associated PCD at runtime, given that its updated value will no longer be used. Signed-off-by: Ard Biesheuvel <ardb@kernel.org>

When building ArmVirtQemuKernel with CLANGDWARF (which does not require a GCC workaround where -mgeneral-regs-only is needed to ensure -mstrict-align works as expected), the C code invoked from the PrePi startup code may contain instructions that access the FP/SIMD register file. This means that the FP/SIMD must be enabled before making such calls, and this is currently not the case. So fix that, by moving the call to ArmEnableVFP() early into the asm startup code.

The ESRT table is not required in UEFI firmware. In such cases, the table may not be present in the UEFI Configuration Table. The mEsrtTable is to check if the IsNestedFmpCapsule() function is invoked at runtime to determine whether to use gEsrtManagementProtocolGuid or the ESRT table from the Configuration Table. Unfortunately, the check does not cover situations where the ESRT is not present, potentially resulting in a kernel crash. This patch is intended to fix this issue.

Following https://bugzilla.tianocore.org/show_bug.cgi?id=2817 this bug could also apply to strncpy and strcat. For strncpy use count+1 if smaller than MAX_STRING_SIZE. This still restricts the destination size to MAX_STRING_SIZE as before but allows a strncpy when the source is close after destination without triggering the InternalSafeStringNoAsciiStrOverlap check in AsciiStrnCpyS. For strcat use the destination string length + the size of the source string including the terminator as destination size if smaller than MAX_STRING_SIZE. Also move both functions to CrtWrapper.c as they do not return the correct return value. AsciiStrnCpyS and AsciiStrCatS return RETURN_VALUE instead of a char * to the destination buffer.

2024-06-07CryptoPkg: Fix BaseCryptLib CrtWrapper strcpySebastian Witt1-1/+1

Copying shall not take place between objects that overlap. // SAFE_STRING_CONSTRAINT_CHECK (InternalSafeStringNoAsciiStrOverlap (Destination, DestMax, (CHAR8 *)Source, SourceLen + 1), RETURN_ACCESS_DENIED); Since DestMax is MAX_STRING_SIZE (0x1000) and with a Source that is in this area behind Destination, AsciiStrCpyS will fail and strcpy will do nothing.
