It looks to be the case that Rust's standard allocator, jemalloc, is
incompatible with sanitizers. The incompatibility, for whatever reason,
seems to cause segfaults at runtime when jemalloc is linked with
sanitizers.
Without actually trying to figure out what's going on here this commit
instead takes the hammer of "let's remove jemalloc when testing". The
`tor_allocate` crate now by default switches to the system allocator
(eventually this will want to be the tor allocator). Most crates then
link to `tor_allocate` ot pick this up, but the `smartlist` crate had to
manually switch to the system allocator in testing and the `external`
crate had to be sure to link to `tor_allocate`.
The final gotcha here is that this patch also switches to
unconditionally passing `--target` to Cargo. For weird and arcane
reasons passing `--target` with the host target of the compiler (which
Cargo otherwise uses as the default) is different than not passing
`--target` at all. This ensure that our custom `RUSTFLAGS` with
sanitizer options doesn't make its way into build scripts, just the
final testing artifacts.
The result of CString::into_raw() is not safe to free
with free() except under finicky and fragile circumstances
that we definitely don't meet right now.
This was missed in be583a34a3.
This argument was added to match an older idea for the C api, but we
decided not to do it that way in C.
Fixes bug 27741; bugfix on 0.3.3.6 / TROVE-2018-005 fix.
.retain() would allocating a Vec of billions of integers and check them
one at a time to separate the supported versions from the unsupported.
This leads to a memory DoS.
Closes ticket 27206. Bugfix on e6625113c9.
It's impossible for spaces to get here, since spaces are used as
separators between individual protocol entries higher up.
And it shouldn't ignore whitespace that isn't a literal space
character, because that would differ from the C implementation.
These were added in 9925d2e687.
Fixes#27177. Bugfix on 0.3.3.5-rc.
It was parsing "1-2-3" as if it were 1-2, ignoring the 2nd hyphen
and everything after.
Introduced in d1820c1516.
Fixes#27164; bugfix on 0.3.3.1-alpha.
The function takes an already validated utf-8 string, and
it never checks if the version numbers are an empty string.
That parse error happens later.
