2022-09-06bionic: Switch to jemalloc memory allocatorDanny Lin
Overall, jemalloc performs significantly better than Scudo in Bionic's real-world memory_replay traces (all times in milliseconds): +----------------+-------+----------+ | Trace | Scudo | jemalloc | +----------------+-------+----------+ | SQL | 27 | 21 | | Angry Birds 2 | 2236 | 1501 | | Camera | 4251 | 979 | | Candy Crush | 2197 | 1325 | | Gmail | 594 | 463 | | Maps | 434 | 344 | | Photos | 1330 | 477 | | PUBG | 666 | 416 | | surfaceflinger | 221 | 192 | | system_server | 1921 | 1416 | | SystemUI | 102 | 79 | | YouTube | 363 | 294 | +----------------+-------+----------+ jemalloc also tends to use slightly less memory than Scudo for most traces.

2022-05-04seccomp: allow stat() for ubsan.Elliott Hughes
We've had complaints about ubsan issues for years, but never got to the bottom of them, or saw them ourselves in testing. For some reason (still not understood) we've started to see this ourselves in T and downstream branches. So for now, let's just punch that extra hole. Longer term, ubsan should stop needing any of this, so once https://reviews.llvm.org/D124212 is in an LTS NDK, we should be able to get rid of this _and_ the existing sanitizer-related holes.

2022-04-29allowlist new Linux close_range() system call, use it in posix_spawn()Maciej Żenczykowski
Linux kernel's close_range() system call (currently) allows: close() unshare() fcntl(F_SETFD, FD_CLOEXEC) to be performed on ranges of fds. All 3 of these are already allowed by seccomp bpf: as such this doesn't allow you to do anything you can't already do. We can't add close_range() properly to bionic because we'd need to fiddle about with ltp and it's too late to add new T API anyway, so let's just make the direct syscall() call. We'll add proper support in U.

2022-04-22Set VIDEO_MAX_FRAME value back to 64.Christopher Ferris
This value was changed from 64 to 32, but it really should not have gone down. So fixing back to 64 manually, and then the next kernel header update should remove the comment but leave the value unchanged. Bug: 228783882 Test: Compiles.
