[PATCH] socket_local46: Make room on the stack for IPv6 sockaddrs

byte_copy() reads past the end of the sockaddr structure because it isn't sufficiently large enough to handle sockaddr_in6 addresses resulting in undefined behavior. armv6-alpine-linux-muslgnueabihf-gcc 5.1.0-r0 generates the "UDF" instruction in this case, causing programs to SIGILL. --- src/libs

[PATCH] s6-supervise: Optionally run child in a new pid namespace

This patch modifies s6-supervise to use the Linux specific clone() system call to enable the child process to become the pid 1 of a new pid namespace. To enable it, compile with -DWANT_CLONE_NEWPID and make the ./clone-newpid file readable to s6-supervise in the desired service directories. I ask

[PATCH 1/2] doc: reconcile openwrite{,v}nclose_suffix{,_devino}{,_sync} with djbunix.h

--- Hello, I've been working with the some of the scatter/gather I/O functions and noticed the documentation duplicated the non-vectored names. On closer inspection, I also discovered the devino variants have their arguments rearranged (except for *_internal). Cheers, Jesse doc/libstddjb
