| | | | | | | | | | | | | | To support Intel CET, all indirect branch targets must start with endbranch. Here is a patch to add endbranch to all function entries in x86 assembly codes which are indirect branch targets as discovered by running openssl testsuite on Intel CET machine and visual inspection.

* Do not silently truncate files on perlasm errorsDavid Benjamin2020-01-222-2/+2
| | | | | | | | | | | | | | | If one of the perlasm xlate drivers crashes, OpenSSL's build will currently swallow the error and silently truncate the output to however far the driver got. This will hopefully fail to build, but better to check such things. Handle this by checking for errors when closing STDOUT (which is a pipe to the xlate driver).

| | | | | | | | | | | | | | | | | | | | The add/double shortcut in ecp_nistz256-x86_64.pl left one instruction point that did not unwind, and the "slow" path in AES_cbc_encrypt was not annotated correctly. For the latter, add .cfi_{remember,restore}_state support to perlasm. Next, fill in a bunch of functions that are missing no-op .cfi_startproc and .cfi_endproc blocks. libunwind cannot unwind those stack frames otherwise. Finally, work around a bug in libunwind by not encoding rflags. (rflags isn't a callee-saved register, so there's not much need to annotate it anyway.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | CFI directives annotate instructions that are significant for stack unwinding procedure. In addition to directives recognized by GNU assembler this module implements three synthetic ones: - .cfi_push annotates push instructions in prologue and translates to .cfi_adjust_cfa_offset (if needed) and .cfi_offset; - .cfi_pop annotates pop instructions in epilogue and translates to .cfi_adjust_cfs_offset (if needed) and .cfi_restore; - .cfi_cfa_expression encodes DW_CFA_def_cfa_expression and passes it to .cfi_escape as byte vector; CFA expression syntax is made up mix of DWARF operator suffixes [subset of] and references to registers with optional bias. Following example describes offloaded original stack pointer at specific offset from current stack pointer: .cfi_cfa_expression %rsp+40,deref,+8 Final +8 has everything to do with the fact that CFA, Canonical Frame Address, is reference to top of caller's stack, and on x86_64 call to subroutine pushes 8-byte return address.
