new in linux v3.17 commit 40e041a2c858b3caefc757e26cb85bfceae5062b sealing allows some operations to be blocked on a file which makes file access safer when fds are shared between processes (only supported for shared mem fds currently) flags: F_SEAL_SEAL prevents further sealing F_SEAL_SHRINK prevents file from shrinking F_SEAL_GROW prevents file from growing F_SEAL_WRITE prevents writes fcntl commands: F_GET_SEALS get the current seal flags F_ADD_SEALS add new seal flags |

musl libc
musl, pronounced like the word "mussel", is an MIT-licensed
implementation of the standard C library targetting the Linux syscall
API, suitable for use in a wide range of deployment environments. musl
offers efficient static and dynamic linking support, lightweight code
and low runtime overhead, strong fail-safe guarantees under correct
usage, and correctness in the sense of standards conformance and
safety. musl is built on the principle that these goals are best
achieved through simple code that is easy to understand and maintain.
The 1.1 release series for musl features coverage for all interfaces
defined in ISO C99 and POSIX 2008 base, along with a number of
non-standardized interfaces for compatibility with Linux, BSD, and
glibc functionality.
For basic installation instructions, see the included INSTALL file.
Information on full musl-targeted compiler toolchains, system
bootstrapping, and Linux distributions built on musl can be found on
the project website:
