From 6a1409b12d47f823a6e77b78823525d5ae65ee7b Mon Sep 17 00:00:00 2001 From: Miles Bader Date: Wed, 20 Dec 1995 22:44:06 +0000 Subject: (proc_stat_set_flags): If there's no owner, set the uid to -1 (and the owner to null), instead of failing. (proc_stat_set_flags): Add support for PROC_OWNER_UID. (add_preconditions): Add preconditions for owner_uid (& owner). --- libps/procstat.c | 22 ++++++++++++++++++++-- 1 file changed, 20 insertions(+), 2 deletions(-) (limited to 'libps') diff --git a/libps/procstat.c b/libps/procstat.c index f53acc5f..100a275b 100644 --- a/libps/procstat.c +++ b/libps/procstat.c @@ -177,6 +177,10 @@ add_preconditions (ps_flags_t flags) flags |= PSTAT_CTTYID; if (flags & PSTAT_STATE) flags |= PSTAT_PROC_INFO | PSTAT_THREAD_BASIC; + if (flags & PSTAT_OWNER) + flags |= PSTAT_OWNER_UID; + if (flags & PSTAT_OWNER_UID) + flags |= PSTAT_PROC_INFO; if (flags & PSTAT_SUSPEND_COUNT) /* We just request the resources require for both the thread and task versions, as the extraneous info won't be possible to aquire anyway. */ @@ -684,9 +688,23 @@ proc_stat_set_flags (proc_stat_t ps, ps_flags_t flags) MP_MGET(PSTAT_UMASK, PSTAT_TASK, msg_get_init_int(ps->msgport, ps->task, INIT_UMASK, &ps->umask)); + if ((need & PSTAT_OWNER_UID) && (have & PSTAT_PROC_INFO)) + { + if (ps->proc_info->state & PI_NOTOWNED) + ps->owner_uid = -1; + else + ps->owner_uid = ps->proc_info->owner; + have |= PSTAT_OWNER_UID; + } + /* A ps_user_t object for the process's owner. */ - if ((need & PSTAT_OWNER) && (have & PSTAT_PROC_INFO)) - if (! ps_context_find_user(ps->context, ps->proc_info->owner, &ps->owner)) + if ((need & PSTAT_OWNER) && (have & PSTAT_OWNER_UID)) + if (ps->owner_uid < 0) + { + ps->owner = 0; + have |= PSTAT_OWNER; + } + else if (! ps_context_find_user(ps->context, ps->owner_uid, &ps->owner)) have |= PSTAT_OWNER; /* A ps_tty_t for the process's controlling terminal, or NULL if it -- cgit v1.2.3
