Re: [libvirt] [PATCH 1/4] util: new virCommandSetMax(MemLock|Processes|Files)

This patch adds two sets of functions: 1) lower level virProcessSet*() functions that will immediately set the RLIMIT_MEMLOCK. RLIMIT_NPROC, or RLIMIT_NOFILE of either the current process (using setrlimit()) or any other process (using prlimit()). "current process" is indicated by passing a 0 for pid. 2) functions for virCommand* that will setup a virCommand object to set those limits at a later time just after it has forked a new process, but before it execs the new program. configure.ac has prlimit and setrlimit added to the list of functions to check for, and the low level functions log an "unsupported" error) on platforms that don't support those functions. --- configure.ac | 2 +- src/libvirt_private.syms | 6 ++ src/util/vircommand.c | 38 ++++++++++++ src/util/vircommand.h | 4 ++ src/util/virprocess.c | 152 ++++++++++++++++++++++++++++++++++++++++++++++- src/util/virprocess.h | 5 +- 6 files changed, 204 insertions(+), 3 deletions(-)
