Subject: [PATCH 2/2] Linux Sandbox: whitelist arm64 syscalls
|
|
|
|
On debian/arm64, two syscalls needed whitelisting for chromium to work with seccomp:
|
|
|
|
epoll_pwait, replacing epoll_wait which is a legacy syscall not available on arm64. epoll_wait implmentation in glibc calls epoll_pwait behind scenes, so this needs to be enabled.
|
|
|
|
getrlimit, missing #ifdef for arm64 in several policy definitions. test for arm64 added for each case.
|
|
|
|
BUG=581018

|
|
TEST=Start chrome on arm64 with seccomp enabled kernel
