From b31cc134e7cca59b8dd67bb30271b80f554e0da0 Mon Sep 17 00:00:00 2001 From: cinap_lenrek Date: Mon, 22 Feb 2016 22:44:01 +0100 Subject: ndb/dns: initialize unknown fids to point to the root qid the dns file service can be restarted, which causes it to forget all fid state. given the simple file system structure of the dns service (just a single dns file), we can assume that rpcs on a unknown fid refers to the root, so the mountpoint will stay valid and /net/dns can be reopend avoiding the need for a remount of the dns service after restart. --- sys/src/cmd/ndb/dns.c | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) (limited to 'sys/src') diff --git a/sys/src/cmd/ndb/dns.c b/sys/src/cmd/ndb/dns.c index 65befe7ae..3b163ca72 100644 --- a/sys/src/cmd/ndb/dns.c +++ b/sys/src/cmd/ndb/dns.c @@ -320,7 +320,10 @@ newfid(int fid, int needunused) } mf = emalloc(sizeof(*mf)); mf->fid = fid; - mf->user = estrdup("dummy"); + mf->qid.vers = vers; + mf->qid.type = QTDIR; + mf->qid.path = 0LL; + mf->user = estrdup("none"); mf->next = mfalloc.inuse; mfalloc.inuse = mf; unlock(&mfalloc); @@ -355,7 +358,7 @@ copyfid(Mfile *mf, int fid) if(nmf == nil) return nil; nmf->fid = fid; - free(nmf->user); /* estrdup("dummy") */ + free(nmf->user); /* estrdup("none") */ nmf->user = estrdup(mf->user); nmf->qid.type = mf->qid.type; nmf->qid.path = mf->qid.path; -- cgit v1.2.3
