[PATCH AUTOSEL 5.5 01/28] thunderbolt: Fix error code in tb_port_is_width_supported()

by Sasha Levin

From: Dan Carpenter <dan.carpenter(a)oracle.com> [ Upstream commit e9d0e7511fda92a6511904996dd0aa57b6d7687a ] This function is type bool, and it's supposed to return true on success. Unfortunately, this path takes negative error codes and casts them to bool (true) so it's treated as success instead of failure.

I mean, it's really only printing a message to the kernel log in this case? At least that's what you're describing. I think you may be describing it wrong, because an NLA_NESTED is allowed to be *empty* (but otherwise must have at least 4 bytes just like an NLA_U32). That said, I'm not even sure I agree that this fix is right? See below. > Is it correct to say that although the code has always been incorrect, > but only kernels after 6e237d099fac need this change? If so, I'll add > Fixes:6e237d099fac to guide the -stable backporting. That doesn't really seem right - 6e237d099fac *relaxed* the checks. If anything then it ought to point to 28033ae4e0f5 which may have actually returned an error; but again, need to understand better what really the issue is. > > diff --git a/kernel/taskstats.c b/kernel/taskstats.c > > index e2ac0e3..b90a520 100644 > > --- a/kernel/taskstats.c > > +++ b/kernel/taskstats.c > > @@ -35,8 +35,8 @@ > > static struct genl_family family; > > > > static const struct nla_policy taskstats_cmd_get_policy[TASKSTATS_CMD_ATTR_MAX+1] = { > > - [TASKSTATS_CMD_ATTR_PID] = { .type = NLA_U32 }, > > - [TASKSTATS_CMD_ATTR_TGID] = { .type = NLA_U32 }, > > + [TASKSTATS_CMD_ATTR_PID] = { .type = NLA_NESTED }, > > + [TASKSTATS_CMD_ATTR_TGID] = { .type = NLA_NESTED }, I'm not sure where this is coming from - the kernel evidently uses them as nested attributes in *outgoing* data (see mk_reply()), but as NLA_U32 in *incoming* data, (see cmd_attr_pid() and cmd_attr_tgid()). I would generally recommend not doing such a thing as it's messy, but we do have quite a few such instances cases. In all those cases must the policy list the incoming policy since that's what the kernel uses to validate the attributes. IOW, this part of the change seems _wrong_. > > * Make sure they are always aligned. > > */ > > static const struct nla_policy cgroupstats_cmd_get_policy[TASKSTATS_CMD_ATTR_MAX+1] = { > > - [CGROUPSTATS_CMD_ATTR_FD] = { .type = NLA_U32 }, > > + [CGROUPSTATS_CMD_ATTR_FD] = { .type = NLA_NESTED }, > > }; And same here, actually. johannes

And looking at this ... well, that code is completely wrong? E.g. rc = send_cmd(nl_sd, id, mypid, TASKSTATS_CMD_GET, cmd_type, &tid, sizeof(__u32)); (cmd_type is one of TASKSTATS_CMD_ATTR_TGID, TASKSTATS_CMD_ATTR_PID) or it might do rc = send_cmd(nl_sd, id, mypid, CGROUPSTATS_CMD_GET, CGROUPSTATS_CMD_ATTR_FD, &cfd, sizeof(__u32)); so clearly it wants to produce a u32 attribute. But then static int send_cmd(int sd, __u16 nlmsg_type, __u32 nlmsg_pid, __u8 genl_cmd, __u16 nla_type, void *nla_data, int nla_len) { ... na = (struct nlattr *) GENLMSG_DATA(&msg); // this is still fine na->nla_type = nla_type; // this is also fine na->nla_len = nla_len + 1 + NLA_HDRLEN; // but this??? the nla_len of a netlink attribute should just be // the len ... what's NLA_HDRLEN doing here? this isn't nested // here we end up just reserving 1+NLA_HDRLEN too much space memcpy(NLA_DATA(na), nla_data, nla_len); // but then it anyway only fills the first nla_len bytes, which // is just like a regular attribute. msg.n.nlmsg_len += NLMSG_ALIGN(na->nla_len); // note that this is also wrong - it should be // += NLA_ALIGN(NLA_HDRLEN + nla_len) So really I think what happened here is precisely what we wanted - David's kernel patch caught the broken userspace tool. johannes
