y2038: globally rename compat_time to old_time32
Christoph Hellwig suggested a slightly different path for handling backwards compatibility with the 32-bit time_t based system calls: Rather than simply reusing the compat_sys_* entry points on 32-bit architectures unchanged, we get rid of those entry points and the compat_time types by renaming them to something that makes more sense on 32-bit architectures (which don't have a compat mode otherwise), and then share the entry points under the new name with the 64-bit architectures that use them for implementing the compatibility. The following types and interfaces are renamed here, and moved from linux/compat_time.h to linux/time32.h: old new --- --- compat_time_t old_time32_t struct compat_timeval struct old_timeval32 struct compat_timespec struct old_timespec32 struct compat_itimerspec struct old_itimerspec32 ns_to_compat_timeval() ns_to_old_timeval32() get_compat_itimerspec64() get_old_itimerspec32() put_compat_itimerspec64() put_old_itimerspec32() compat_get_timespec64() get_old_timespec32() compat_put_timespec64() put_old_timespec32() As we already have aliases in place, this patch addresses only the instances that are relevant to the system call interface in particular, not those that occur in device drivers and other modules. Those will get handled separately, while providing the 64-bit version of the respective interfaces. I'm not renaming the timex, rusage and itimerval structures, as we are still debating what the new interface will look like, and whether we will need a replacement at all. This also doesn't change the names of the syscall entry points, which can be done more easily when we actually switch over the 32-bit architectures to use them, at that point we need to change COMPAT_SYSCALL_DEFINEx to SYSCALL_DEFINEx with a new name, e.g. with a _time32 suffix.

Merge branch 'ida-4.19' of git://git.infradead.org/users/willy/linux-dax
Pull IDA updates from Matthew Wilcox:
"A better IDA API:
id = ida_alloc(ida, GFP_xxx);
ida_free(ida, id);
rather than the cumbersome ida_simple_get(), ida_simple_remove().
The new IDA API is similar to ida_simple_get() but better named. The
internal restructuring of the IDA code removes the bitmap
preallocation nonsense.
I hope the net -200 lines of code is convincing"

NFSv4.0 callback needs to know the GSS target name the client used when it established its lease. That information is available from the GSS context created by gssproxy.

A multi-homed NFS server may have more than one "nfs" key in its keytab. Enable the kernel to pick the key it wants as a machine credential when establishing a GSS context. This is useful for GSS-protected NFSv4.0 callbacks, which are required by RFC 7530 S3.3.3 to use the same principal as the service principal the client used when establishing its lease. A complementary modification to rpc.gssd is required to fully enable this feature. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: J. Bruce Fields <bfields@redhat.com> |

ip6_vti: fix creating fallback tunnel device for vti6
When set fb_tunnels_only_for_init_net to 1, don't create fallback tunnel

net: sched: always disable bh when taking tcf_lock
Recently, ops->init() and ops->dump() of all actions were modified to always obtain tcf_lock when accessing private action state. Actions that don't depend on tcf_lock for synchronization with their data path use non-bh locking API. However, tcf_lock is also used to protect rate estimator stats in softirq context by timer callback. Change ops->init() and ops->dump() of all actions to disable bh when using tcf_lock to prevent deadlock reported by following lockdep warning: [ 105.470398] ================================ [ 105.475014] WARNING: inconsistent lock state [ 105.479628] 4.18.0-rc8+ #664 Not tainted [ 105.483897] -------------------------------- [ 105.488511] inconsistent {SOFTIRQ-ON-W} -> {IN-SOFTIRQ-W} usage.

The following patchset contains Netfilter/IPVS fixes for your net tree:
1) Infinite loop in IPVS when net namespace is released, from
Tan Hu.
2) Do not show negative timeouts in ip_vs_conn by using the new
jiffies_delta_to_msecs(), patches from Matteo Croce.
3) Set F_IFACE flag for linklocal addresses in ip6t_rpfilter,
from Florian Westphal.
4) Fix overflow in set size allocation, from Taehee Yoo.
5) Use netlink_dump_start() from ctnetlink to fix memleak from
the error path, again from Florian.
6) Register nfnetlink_subsys in last place, otherwise netns
init path may lose race and see net->nft uninitialized data.
This also reverts previous attempt to fix this by increase
netns refcount, patches from Florian.
7) Remove conntrack entries on layer 4 protocol tracker module

RDMA/smc: Replace ib_query_gid with rdma_get_gid_attr
All RDMA ULPs should be using rdma_get_gid_attr instead of ib_query_gid. Convert SMC to use the new API. In the process correct some confusion with gid_type - if attr->ndev is !NULL then gid_type can never be IB_GID_TYPE_IB by definition. IB_GID_TYPE_ROCE shares the same enum value and is probably what was intended here. Reviewed-by: Parav Pandit <parav@mellanox.com> Signed-off-by: Jason Gunthorpe <jgg@mellanox.com> |

tcp, ulp: fix leftover icsk_ulp_ops preventing sock from reattach
I found that in BPF sockmap programs once we either delete a socket
from the map or we updated a map slot and the old socket was purged
from the map that these socket can never get reattached into a map
even though their related psock has been dropped entirely at that
point.
Reason is that tcp_cleanup_ulp() leaves the old icsk->icsk_ulp_ops
intact, so that on the next tcp_set_ulp_id() the kernel returns an
-EEXIST thinking there is still some active ULP attached.
BPF sockmap is the only one that has this issue as the other user,
kTLS, only calls tcp_cleanup_ulp() from tcp_v4_destroy_sock() whereas
sockmap semantics allow dropping the socket from the map with all
related psock state being cleaned up.

tcp, ulp: add alias for all ulp modules
Lets not turn the TCP ULP lookup into an arbitrary module loader as
we only intend to load ULP modules through this mechanism, not other
unrelated kernel modules:
[root@bar]# cat foo.c
#include <sys/types.h>
#include <sys/socket.h>
#include <linux/tcp.h>
#include <linux/in.h>
int main(void)
{
int sock = socket(PF_INET, SOCK_STREAM, 0);
setsockopt(sock, IPPROTO_TCP, TCP_ULP, "sctp", sizeof("sctp"));
return 0;
}
[root@bar]# gcc foo.c -O2 -Wall
[root@bar]# lsmod | grep sctp
[root@bar]# ./a.out
[root@bar]# lsmod | grep sctp
sctp 1077248 4
libcrc32c 16384 3 nf_conntrack,nf_nat,sctp
[root@bar]#
Fix it by adding module alias to TCP ULP modules, so probing module
via request_module() will be limited to tcp-ulp-[name]. The existing
modules like kTLS will load fine given tcp-ulp-tls alias, but others
will fail to load:
[root@bar]# lsmod | grep sctp
[root@bar]# ./a.out
[root@bar]# lsmod | grep sctp
[root@bar]#
Sockmap is not affected from this since it's either built-in or not.

net: sched: act_ife: always release ife action on init error
Action init API was changed to always take reference to action, even when
overwriting existing action. Substitute conditional action release, which
was executed only if action is newly created, with unconditional release in
tcf_ife_init() error handling code to prevent double free or memory leak in
case of overwrite.

netfilter: nft_tproxy: Fix missing-braces warning
This patch fixes a warning reported by the kbuild test robot (from linux-next
tree):
net/netfilter/nft_tproxy.c: In function 'nft_tproxy_eval_v6':
>> net/netfilter/nft_tproxy.c:85:9: warning: missing braces around initializer [-Wmissing-braces]
struct in6_addr taddr = {0};
^
net/netfilter/nft_tproxy.c:85:9: warning: (near initialization for 'taddr.in6_u') [-Wmissing-braces]
This warning is actually caused by a gcc bug already resolved in newer
versions (kbuild used 4.9) so this kind of initialization is omitted and
memset is used instead.

netfilter: nf_tables: don't prevent event handler from device cleanup on netns exit
When a netnsamespace exits, the nf_tables pernet_ops will remove all rules.
However, there is one caveat:
Base chains that register ingress hooks will cause use-after-free:
device is already gone at that point.
The device event handlers prevent this from happening:
netns exit synthesizes unregister events for all devices.
However, an improper fix for a race condition made the notifiers a no-op
in case they get called from netns exit path, so revert that part.
This is safe now as the previous patch fixed nf_tables pernet ops
and device notifier initialisation ordering.

netfilter: nf_tables: fix register ordering
We must register nfnetlink ops last, as that exposes nf_tables to

netfilter: fix memory leaks on netlink_dump_start error
Shaochun Chen points out we leak dumper filter state allocations
stored in dump_control->data in case there is an error before netlink sets
cb_running (after which ->done will be called at some point).
In order to fix this, add .start functions and move allocations there.
Same pattern as used in commit

netfilter: nft_set: fix allocation size overflow in privsize callback.
In order to determine allocation size of set, ->privsize is invoked.
At this point, both desc->size and size of each data structure of set
are used. desc->size means number of element that is given by user.
desc->size is u32 type. so that upperlimit of set element is 4294967295.
but return type of ->privsize is also u32. hence overflow can occurred.
test commands:
%nft add table ip filter
%nft add set ip filter hash1 { type ipv4_addr \; size 4294967295 \; }
%nft list ruleset

(i.e. IP_VS_DEST_F_AVAILABLE), the packet will be dropped sliently.
But if the dropped packet is the first packet of this connection,
the connection control timer never has a chance to start and the
ipvs connection cannot be released. This will lead to memory leak, or
infinite loop in cleanup_net() when net namespace is released like
this:
ip_vs_conn_net_cleanup at ffffffffa0a9f31a [ip_vs]
__ip_vs_cleanup at ffffffffa0a9f60a [ip_vs]
ops_exit_list at ffffffff81567a49
cleanup_net at ffffffff81568b40
process_one_work at ffffffff810a851b
worker_thread at ffffffff810a9356
kthread at ffffffff810b0b6f
ret_from_fork at ffffffff81697a18
race condition:
CPU1 CPU2
ip_vs_in()
ip_vs_conn_new()
ip_vs_del_dest()
__ip_vs_unlink_dest()
~IP_VS_DEST_F_AVAILABLE
cp->dest && !IP_VS_DEST_F_AVAILABLE
__ip_vs_conn_put
...
cleanup_net ---> infinite looping
Fix this by checking whether the timer already started.

Pull LED updates from Jacek Anaszewski:
"LED triggers improvements make the biggest part of this pull request.
The most striking ones, that allowed for nice cleanups in the triggers
are:
- centralized handling of creation and removal of trigger sysfs
attributes via attribute group
- addition of module_led_trigger() helper
The other things that need to be mentioned:
New features and improvements to existing LED class drivers:
- lt3593: add DT support, switch to gpiod interface
- lm3692x: support LED sync configuration, change OF calls to fwnode
calls
- apu: modify PC Engines apu/apu2 driver to support apu3
Change in the drivers/net/can/led.c:
- mark led trigger as broken since it's in the way for the further
cleanups. It implements a subset of the netdev trigger and an Ack
is needed from someone who can actually test and confirm that the
netdev trigger works for can devices"

rds: fix building with IPV6=m
When CONFIG_RDS_TCP is built-in and CONFIG_IPV6 is a loadable
module, we get a link error agains the modular ipv6_chk_addr()
function:
net/rds/tcp.o: In function `rds_tcp_laddr_check':
tcp.c:(.text+0x3b2): undefined reference to `ipv6_chk_addr'
This adds back a dependency that forces RDS_TCP to also be
a loadable module when IPV6 is one.
Fixes:
