2020-02-17Also check for errors in x86_64-xlate.pl.David Benjamin
In https://github.com/openssl/openssl/pull/10883, I'd meant to exclude the perlasm drivers since they aren't opening pipes and do not particularly need it, but I only noticed x86_64-xlate.pl, so arm-xlate.pl and ppc-xlate.pl got the change. That seems to have been fine, so be consistent and also apply the change to x86_64-xlate.pl. Checking for errors is generally a good idea.

2020-02-15x86_64: Add endbranch at function entries for Intel CETH.J. Lu
To support Intel CET, all indirect branch targets must start with endbranch. Here is a patch to add endbranch to function entries in x86_64 assembly codes which are indirect branch targets as discovered by running openssl testsuite on Intel CET machine and visual inspection. Verified with $ CC="gcc -Wl,-z,cet-report=error" ./Configure shared linux-x86_64 -fcf-protection $ make $ make test and $ CC="gcc -mx32 -Wl,-z,cet-report=error" ./Configure shared linux-x32 -fcf-protection $ make $ make test # <<< passed with https://github.com/openssl/openssl/pull/10988 Reviewed-by: Tomas Mraz <tmraz@fedoraproject.org> Reviewed-by: Richard Levitte <levitte@openssl.org> (Merged from https://github.com/openssl/openssl/pull/10982)
2020-01-22Do not silently truncate files on perlasm errorsDavid Benjamin
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).

2019-09-16Unify all assembler file generatorsRichard Levitte
They now generally conform to the following argument sequence: script.pl "$(PERLASM_SCHEME)" [ C preprocessor arguments ... ] \ $(PROCESSOR) <output file> However, in the spirit of being able to use these scripts manually, they also allow for no argument, or for only the flavour, or for only the output file. This is done by only using the last argument as output file if it's a file (it has an extension), and only using the first argument as flavour if it isn't a file (it doesn't have an extension). While we're at it, we make all $xlate calls the same, i.e. the $output argument is always quoted, and we always die on error when trying to start $xlate. There's a perl lesson in this, regarding operator priority... This will always succeed, even when it fails: open FOO, "something" || die "ERR: $!"; The reason is that '||' has higher priority than list operators (a function is essentially a list operator and gobbles up everything following it that isn't lower priority), and since a non-empty string is always true, so that ends up being exactly the same as: open FOO, "something"; This, however, will fail if "something" can't be opened: open FOO, "something" or die "ERR: $!"; The reason is that 'or' has lower priority that list operators, i.e. it's performed after the 'open' call.

2016-10-10Remove trailing whitespace from some files.David Benjamin
The prevailing style seems to not have trailing whitespace, but a few lines do. This is mostly in the perlasm files, but a few C files got them after the reformat. This is the result of: find . -name '*.pl' | xargs sed -E -i '' -e 's/( |'$'\t'')*$//' find . -name '*.c' | xargs sed -E -i '' -e 's/( |'$'\t'')*$//' find . -name '*.h' | xargs sed -E -i '' -e 's/( |'$'\t'')*$//' Then bn_prime.h was excluded since this is a generated file. Note mkerr.pl has some changes in a heredoc for some help output, but other lines there lack trailing whitespace too.
