2016-04-18syscalls: If a syscall is not available, defer the error.Mark H Weaver
* guix/build/syscalls.scm (syscall->procedure): New procedure. (mount, umount, swapon, swapoff, clone, pivot-root): Use it. (clone): Add case for nonexistent syscall id. Signed-off-by: Ludovic Courtès <ludo@gnu.org>
2016-04-16syscalls: 'terminal-columns' ignores non-file ports.Ludovic Courtès
* guix/build/syscalls.scm (terminal-columns): Call 'terminal-window-size' only when PORT is a file port. * tests/syscalls.scm ("terminal-columns non-file port"): New test.
2016-04-15syscalls: Add TIOCGWINSZ bindings.Ludovic Courtès

2016-03-25syscalls: <interface> printer correctly handles lack of sockaddr.Ludovic Courtès
Reported by Danny Milosavljevic <dannym@scratchpost.org> in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=22612#16>. * guix/build/syscalls.scm (write-interface): Check whether ADDRESS is true.
2016-02-03syscalls: 'all-network-interface-names' accepts non-alphanumeric characters.Ludovic Courtès
This fixes interfaces with a dash or other characters being ignored. Suggested by Jookia <166291@gmail.com>. * guix/build/syscalls.scm (%interface-line): Use [[:graph:]] instead of [[:alnum:]].
2015-10-17syscalls: Fix ABI mismatch for 'clone'.Ludovic Courtès
Fixes <http://bugs.gnu.org/21694>. * guix/build/syscalls.scm (clone): Change 'syscall' parameter types to LONG, UNSIGNED-LONG, or '*; make sure it has 6 parameters. Adjust caller accordingly.
2015-09-07build: container: Use the same clone flags as fork(3).David Thompson
The intent is to make 'clone' behave a lot more like 'primitive-fork', which calls clone(2) with SIGCHLD, CLONE_CHILD_CLEARTID, and CLONE_CHILD_SETTID flags. Notably, running 'clone' at the REPL without these flags would break the REPL beyond repair. * guix/build/syscalls.scm (CLONE_CHILD_CLEARTID, CLONE_CHILD_SETTID): New variables. * gnu/build/linux-container.scm (namespaces->bit-mask): Add CLONE_CHILD_CLEARTID and CLONE_CHILD_SETTID to bit mask.

(%struct-ifaddrs-type, %sizeof-ifaddrs): New macros. * tests/syscalls.scm ("network-interfaces returns one or more interfaces", "network-interfaces returns \"lo\""): New tests.
2015-07-25syscalls: 'define-c-struct' properly align reads.Ludovic Courtès
* guix/build/syscalls.scm (alignof*, align): New macros. (write-types, read-types): Use 'align' to compute the actual offset to read/write a value of TYPE0.
