Subject: Re: [RFC PATCH v2] grep: allow for run time disabling of JIT in PCRE
Date: Mon, 29 Jul 2019 04:33:45 -0700
Message-ID: <CAPUEspi7jvGEx_3CMPpYp7_gip0Mv=+MZdfWYoj+NJmomXJTHw@mail.gmail.com> (raw)
In-Reply-To: <20190729105955.44390-1-carenas@gmail.com>

Known Issues:
* PCRE1 is broken, but fixing it would make more sense on top of the
topic[1] (not in pu)
* it depends on the current ab/pcre-jit-fixes that is missing 1
critical commit in pu
* no tests yet; would need to extend it on top of the debug from Beat
and test-tool changes from Ævar, neither of which are final
* need to build on top of pu and will need further changes to be ready
for next/master/maint

The code has been tested in OpenBSD with PCRE2 (latest from svn, but
any version should work if they are JIT enabled), it is
expected to also work in NetBSD (even with PAX enabled kernels) and
macOS 10.13.6 but haven't yet tested them.  HardenedBSD
will likely segfault unless pcre.jit=0 as described in the original report[2]

Testing with SElinux and PAX enabled for Linux encouraged
