2011-07-12os-posix: set groups properly for -runasStefan Hajnoczi
Andrew Griffiths reports that -runas does not set supplementary group IDs. This means that gid 0 (root) is not dropped when switching to an unprivileged user. Add an initgroups(3) call to use the -runas user's /etc/groups membership to update the supplementary group IDs.

2011-06-15Introduce format string for pid_tAndreas Färber
BeOS and Haiku on i386 use long for 32-bit types, including pid_t. Using %d with pid_t therefore results in a warning. Unfortunately POSIX:2008 does not define a PRId* string for pid_t. In some places pid_t was previously casted to long and %ld hardcoded. The predecessor of this patch added another upcast for the simpletrace filename but was not applied to date. Since new uses of pid_t with %d keep creeping in, let's instead define an OS-dependent format string and use that consistently.

2011-03-29add a service to reap zombies, use it in SLIRPPaolo Bonzini
SLIRP -smb support wants to fork a process and forget about reaping it. To please it, add a generic service to register a process id and let QEMU reap it. In the future it could be enhanced to pass a status, but this would be unused. With this in place, the SIGCHLD signal handler would not stomp on pclose anymore.

2011-03-26report that QEMU process was killed by a signalGleb Natapov
Currently when rogue script kills QEMU process (using TERM/INT/HUP signal) it looks indistinguishable from system shutdown. Lets report that QEMU was killed and leave some clues about the killer identity. Signed-off-by: Gleb Natapov <gleb@redhat.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-03-16Expose thread_id in info cpusJan Kiszka
Based on patch by Glauber Costa: To allow management applications like libvirt to apply CPU affinities to the VCPU threads, expose their ID via info cpus. This patch provides the pre-existing and used interface from qemu-kvm. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>

2010-08-20Use ARRAY_SIZE macroBlue Swirl
Replace array size calculations with ARRAY_SIZE macro. Implemented with this Coccinelle semantic patch, adapted from Linux kernel: @@ type T; T[] E; @@ - (sizeof(E)/sizeof(*E)) + ARRAY_SIZE(E) @@ type T; T[] E; @@ - (sizeof(E)/sizeof(E[...])) + ARRAY_SIZE(E) @@ type T; T[] E; @@ - (sizeof(E)/sizeof(T)) + ARRAY_SIZE(E) Some files (*-dis.c, tests/*) had to be filtered out.

2010-07-06Include sys/mman.h before qemu-options.hJes Sorensen
