syscall: call setgroups for no groups on GNU/Linux

2016-06-02T17:21:34+00:00

Skip setgroups only for one particular case: GidMappings != nil and
GidMappingsEnableSetgroup == false and list of supplementary groups is
empty.
This patch returns pre-1.5 behavior for simple exec and still allows to
use GidMappings with non-empty Credential.

syscall: rename SysProcAttr.Unshare to Unshareflags

2016-06-01T04:27:28+00:00

For symmetry with Cloneflags and it looks slightly weird because there
is syscall.Unshare method.

syscall: fix accidental close of exec status pipe in StartProcess

2016-03-29T00:03:14+00:00

In syscall.forkAndExecInChild, blocks of code labelled Pass 1
and Pass 2 permute the file descriptors (if necessary) which are
passed to the child process.  If Pass 1 begins with fds = {0,2,1},
nextfd = 4 and pipe = 4, then the statement labelled "don't stomp
on pipe" is too late -- the pipe (which will be needed to pass
exec status back to the parent) will have been closed by the
preceding DUP call.

Moving the "don't stomp" test earlier ensures that the pipe is
protected.

Fixes #14979

all: single space after period.

2016-03-02T00:13:47+00:00

The tree's pretty inconsistent about single space vs double space
after a period in documentation. Make it consistently a single space,
per earlier decisions. This means contributors won't be confused by
misleading precedence.

syscall: don't call Setgroups if Credential.Groups is empty

2015-08-27T16:08:01+00:00

Setgroups with zero-length groups is no-op for changing groups and
supposed to be used only for determining curent groups length. Also
because we deny setgroups by default if use GidMappings we have
unnecessary error from that no-op syscall.
