Hi!
I have reproduced the problem. I have a (refined) trackback with more
information:
(gdb) bt full
#0 __strlen_sse2 () at ../sysdeps/x86_64/multiarch/../strlen.S:32
No locals.
#1 0x00002aaaab885357 in xdr_string (xdrs=xdrs@entry=0x7fffffffcf90,
cpp=cpp@entry=0x7fffffffd0f8, maxsize=maxsize@entry=4294967295) at
xdr.c:680
sp = 0x1c52ab7fd960 <Address 0x1c52ab7fd960 out of bounds>
size = <optimized out>
nodesize = <optimized out>
__func__ = "xdr_string"
#2 0x00002aaaab159061 in xdr_gf1_cli_create_vol_rsp
(xdrs=xdrs@entry=0x7fffffffcf90,
objp=objp@entry=0x7fffffffd0f0) at cli1-xdr.c:279
No locals.
#3 0x00002aaaaaf44f11 in xdr_serialize_generic (outmsg=...,
res=0x7fffffffd0f0,
proc=0x2aaaab159010 <xdr_gf1_cli_create_vol_rsp>) at rpc-common.c:36
ret = -1
xdr = {x_op = XDR_ENCODE, x_ops = 0x2aaaabb01860, x_public = 0x0,
x_private = 0x2aaaac2cc008 "", x_base = 0x2aaaac2cc000
"\377\377\321@",
x_handy = 131064}
__FUNCTION__ = "xdr_serialize_generic"
#4 0x00002aaaacb6b906 in glusterd_serialize_reply
(req=req@entry=0x2aaaacdac024,
arg=0x7fffffffd0f0, sfunc=0x2aaaab15a250
<gf_xdr_serialize_cli_create_vol_rsp>,
outmsg=outmsg@entry=0x7fffffffd020) at glusterd-utils.c:402
iob = 0x555555783760
retlen = -1
__FUNCTION__ = "glusterd_serialize_reply"
I suspect, that objp->volname (at cli1-xdr.c:279) contains uninitialized memory,
and when xdr_string tries to perform a strlen on that, it breaks, down.
Cheers,
Paul
