This enables legacy seccomp sandbox by default even on chromium 22, because the
BPF sandbox is still work in progress, please see:
http://crbug.com/139872http://crbug.com/130662
Because the BPF seccomp sandbox is used in case the legacy seccomp mode
initialization fails, we might need to patch this again, as soon as the BPF
sandbox is fully implemented to fall back to legacy seccomp and use BPF by
default.
We now have two patches for "default to seccomp" - one for Chromium 21 and one
for 22 or higher.
Users might want to override the 'src' and 'name' of go from 'hg'.
I make the expression compatible with that.
Aside, I also set GOARM in the wrapper for it to build programs fine on
armv5tel by default.
The patch doesn't apply in version 22 and newer, because mode 1 sandboxes are
connsidered "legacy" (well, apart from the fact that I'd personally prefer BPF
anyway), for reasons I wasn't able to find, yet. But let's proceed on BPF
integration and thus gain more insight on the exact reasons.
If you look at what changed, you'll surely notice that version 22 is now in
beta, so we have to expect things to break. And one thing that will break for
sure is the seccomp patch, because beginning with 22 the new BPF seccomp sandbox
is going to replace the mode 1 seccomp sandbox.
This commit doesn't add any feature and just fixes a small annoyance which
result in messages like this:
Checking if xxx applies...no.
See that there is no whitespace between "..." and "no"? Well, the world cares
for more important things, but for me personally those minor annoyances can turn
into major annoyances.
The previous version seemed rather old and not even the examples from the
official site compile with that fossil. As there are no reverse dependencies,
this update should be trivial and hopefully doesn't hurt someones personal
feelings.
