[alsa-devel] [RESEND] [PATCH 0/3] Close alsa-lib file descriptors on exec

[Rémi Denis-Courmont]

        Hello,

The device nodes opened by alsa-lib are private, and are not meant to be used 
after exec(). Setting the close-on-exec flags avoid leaking devices file 
descriptors into unintended processes. Further more, the Linux kernel 
O_CLOEXEC flag is used if available for fully thread-safe operations.
