When the libcrypto feature test was added we forgot to add its
FEATURE_CHECK_LDFLAGS pointing to the library needed to link with the
test-all.bin feature test fast path binary, so even when it was
introduced we got this:
$ cat /tmp/build/perf/feature/test-all.make.output
/usr/bin/ld: /tmp/ccjKeJJU.o: in function `main_test_libcrypto':
/home/acme/git/perf/tools/build/feature/test-libcrypto.c:10: undefined reference to `MD5_Init'
/usr/bin/ld: /home/acme/git/perf/tools/build/feature/test-libcrypto.c:11: undefined reference to `MD5_Update'
/usr/bin/ld: /home/acme/git/perf/tools/build/feature/test-libcrypto.c:12: undefined reference to `MD5_Final'
/usr/bin/ld: /home/acme/git/perf/tools/build/feature/test-libcrypto.c:14: undefined reference to `SHA1'
collect2: error: ld returned 1 exit status
$ cat /tmp/build/perf/feature/test-libcrypto.
test-libcrypto.bin test-libcrypto.d test-libcrypto.make.output
$ cat /tmp/build/perf/feature/test-libcrypto.make.output
$
Fix it, so that we keep the fast path, which, at this point, will fail
with the unwind-ARCH feature tests, that will be fixed in a followup
patch:
$ make -C tools/perf O=/tmp/build/perf
... libcrypto: [ on ]
<SNIP>
$ cat /tmp/build/perf/feature/test-all.make.output
$ ldd /tmp/build/perf/feature/test-all.bin | grep libcrypto
libcrypto.so.1.1 => /lib64/libcrypto.so.1.1 (0x00007f9892805000)
$
$ grep libcrypto /tmp/build/perf/FEATURE-DUMP
feature-libcrypto=1
$
With the unwind-ARCH tests fixed, we now finally manage to get
test-all.bin built and linked with the features it tests, among them the
ones fixed in this patchkit:
$ ldd /tmp/build/perf/feature/test-all.bin | egrep 'unwind|crypto'
libcrypto.so.1.1 => /lib64/libcrypto.so.1.1 (0x00007f95cf2b8000)
libunwind-x86_64.so.8 => /lib64/libunwind-x86_64.so.8 (0x00007f95cf294000)
libunwind.so.8 => /lib64/libunwind.so.8 (0x00007f95cf278000)

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
