## Meeting Notes
- Alpine Linux intro [slides](https://dev.alpinelinux.org/~ncopa/presentations/alpine-security-mission.html)
- Question: what's the strategy for getting rid of SUID? File capabilities?
- Answer: no real plan
- Question: what's the strategy in the face of no more public GRSecurity
patches?
- Answer: Currently forward porting last test patch, slightly risky, not a
good solution. May discontinue use at some point.
- Question: Thoughts on capabilities?
- Answer: fs-caps sound like a nice way to get rid of SUID bits, since
they're uid-independent.
- Question: Thoughts on LSMs?
- Answer: SELinux is complicated, AppArmor is simpler and perhaps better in
that sense, not on the roadmap currently for Alpine to implement default
profiles (but may be in the future)
- Question: What exactly is the deal with TLS?
- glibc does *lazy* allocation, so after pthread_create(), at some later
point, the actual allocation for TLS may fail, and glibc simply aborts().
This is one reason dlopen is a noop, but not the only reason.
