Reject attempts to repeatedly toggle the 'dormant' flag in a single transaction. Doing so makes nf_tables lose track of the real state vs. the desired state. This ends with an attempt to unregister hooks that were never registered in the first place, which yields a splat. 2. Fix element counting in the new nftables garbage collection infra that came with 6.5: More than 255 expired elements wraps a counter which results in memory leak. 3. Since 6.4 ipset can BUG when a set is renamed while a CREATE command is in progress, fix from Jozsef Kadlecsik. * tag 'nf-23-09-20' of https://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf: netfilter: ipset: Fix race between IPSET_CMD_CREATE and IPSET_CMD_SWAP netfilter: nf_tables: fix memleak when more than 255 elements expired netfilter: nf_tables: disable toggling dormant table state more than once ==================== Link: https://lore.kernel.org/r/20230920084156.4192-1-fw@strlen.de Signed-off-by: Paolo Abeni <pabeni@redhat.com> |

net/handshake: Fix memory leak in __sock_create() and sock_alloc_file()
When making CONFIG_DEBUG_KMEMLEAK=y and CONFIG_DEBUG_KMEMLEAK_AUTO_SCAN=y,
modprobe handshake-test and then rmmmod handshake-test, the below memory
leak is detected.
The struct socket_alloc which is allocated by alloc_inode_sb() in
__sock_create() is not freed. And the struct dentry which is allocated
by __d_alloc() in sock_alloc_file() is not freed.
Since fput() will call file->f_op->release() which is sock_close() here and
it will call __sock_release(). and fput() will call dput(dentry) to free
the struct dentry. So replace sock_release() with fput() to fix the
below memory leak. After applying this patch, the following memory leak is
never detected.

netfilter: ipset: Fix race between IPSET_CMD_CREATE and IPSET_CMD_SWAP
Kyle Zeng reported that there is a race between IPSET_CMD_ADD and IPSET_CMD_SWAP
in netfilter/ip_set, which can lead to the invocation of `__ip_set_put` on a
wrong `set`, triggering the `BUG_ON(set->ref == 0);` check in it.
The race is caused by using the wrong reference counter, i.e. the ref counter instead
of ref_netlink.

netfilter: nf_tables: fix memleak when more than 255 elements expired
When more than 255 elements expired we're supposed to switch to a new gc
container structure.
This never happens: u8 type will wrap before reaching the boundary
and nft_trans_gc_space() always returns true.
This means we recycle the initial gc container structure and
lose track of the elements that came before.
While at it, don't deref 'gc' after we've passed it to call_rcu.

netfilter: nf_tables: disable toggling dormant table state more than once
nft -f -<<EOF
add table ip t
add table ip t { flags dormant; }
add chain ip t c { type filter hook input priority 0; }
add table ip t
EOF
Triggers a splat from nf core on next table delete because we lose
track of right hook register state:

The above should have table in *active* state, but in fact no
hooks were registered.
Reject on/off/on games rather than attempting to fix this.

mptcp: fix dangling connection hang-up
According to RFC 8684 section 3.3: A connection is not closed unless [...] or an implementation-specific connection-level send timeout. Currently the MPTCP protocol does not implement such timeout, and connection timing-out at the TCP-level never move to close state. Introduces a catch-up condition at subflow close time to move the MPTCP socket to close, too. That additionally allows removing similar existing inside the worker. Finally, allow some additional timeout for plain ESTABLISHED mptcp sockets, as the protocol allows creating new subflows even at that point and making the connection functional again. This issue is actually present since the beginning, but it is basically impossible to solve without a long chain of functional pre-requisites topped by commit |

events and retransmissions. The existing helpers do not indicate
clearly which timer they actually touch, making the related code
quite confusing.
Change the existing helpers name to avoid such confusion. No
functional change intended.
This patch is linked to the next one ("mptcp: fix dangling connection
hang-up"). The two patches are supposed to be backported together.

mptcp: process pending subflow error on close
On incoming TCP reset, subflow closing could happen before error
propagation. That in turn could cause the socket error being ignored,
and a missing socket state transition, as reported by Daire-Byrne.
Address the issues explicitly checking for subflow socket error at
close time. To avoid code duplication, factor-out of __mptcp_error_report()
a new helper implementing the relevant bits.
Closes: https://github.com/multipath-tcp/mptcp_net-next/issues/429

mptcp: fix bogus receive window shrinkage with multiple subflows
In case multiple subflows race to update the mptcp-level receive
window, the subflow losing the race should use the window value
provided by the "winning" subflow to update it's own tcp-level
rcv_wnd.
To such goal, the current code bogusly uses the mptcp-level rcv_wnd
value as observed before the update attempt. On unlucky circumstances
that may lead to TCP-level window shrinkage, and stall the other end.
Address the issue feeding to the rcv wnd update the correct value.

net: hsr: Add __packed to struct hsr_sup_tlv.
Struct hsr_sup_tlv describes HW layout and therefore it needs a __packed attribute to ensure the compiler does not add any padding. Due to the size and __packed attribute of the structs that use hsr_sup_tlv it has no functional impact. Add __packed to struct hsr_sup_tlv.

net: hsr: Properly parse HSRv1 supervisor frames.
While adding support for parsing the redbox supervision frames, the
author added `pull_size' and `total_pull_size' to track the amount of
bytes that were pulled from the skb during while parsing the skb so it
can be reverted/ pushed back at the end.
In the process probably copy&paste error occurred and for the HSRv1 case
the ethhdr was used instead of the hsr_tag. Later the hsr_tag was used
instead of hsr_sup_tag. The later error didn't matter because both
structs have the size so HSRv0 was still working. It broke however HSRv1
parsing because struct ethhdr is larger than struct hsr_tag.
Reinstate the old pulling flow and pull first ethhdr, hsr_tag in v1 case
followed by hsr_sup_tag.

dccp: fix dccp_v4_err()/dccp_v6_err() again
dh->dccph_x is the 9th byte (offset 8) in "struct dccp_hdr",
not in the "byte 7" as Jann claimed.
We need to make sure the ICMP messages are big enough,
using more standard ways (no more assumptions).

ipv4: fix null-deref in ipv4_link_failure
Currently, we assume the skb is associated with a device before calling
__ip_options_compile, which is not always the case if it is re-routed by
ipvs.
When skb->dev is NULL, dev_net(skb->dev) will become null-dereference.
This patch adds a check for the edge case and switch to use the net_device
from the rtable when skb->dev is NULL.

netfilter, bpf: Adjust timeouts of non-confirmed CTs in bpf_ct_insert_entry()
bpf_nf testcase fails on s390x: bpf_skb_ct_lookup() cannot find the entry
that was added by bpf_ct_insert_entry() within the same BPF function.
The reason is that this entry is deleted by nf_ct_gc_expired().
The CT timeout starts ticking after the CT confirmation; therefore
nf_conn.timeout is initially set to the timeout value, and
__nf_conntrack_confirm() sets it to the deadline value.
bpf_ct_insert_entry() sets IPS_CONFIRMED_BIT, but does not adjust the
timeout, making its value meaningless and causing false positives.
Fix the problem by making bpf_ct_insert_entry() adjust the timeout,
like __nf_conntrack_confirm().

This operation is not destructive, therefore, turn write into read spinlock to avoid datapath contention due to GC worker run.

net/core: Fix ETH_P_1588 flow dissector
When a PTP ethernet raw frame with a size of more than 256 bytes followed
by a 0xff pattern is sent to __skb_flow_dissect, nhoff value calculation
is wrong. For example: hdr->message_length takes the wrong value (0xffff)
and it does not replicate real header length. In this case, 'nhoff' value
was overridden and the PTP header was badly dissected. This leads to a
kernel crash.
net/core: flow_dissector
net/core flow dissector nhoff = 0x0000000e
net/core flow dissector hdr->message_length = 0x0000ffff
net/core flow dissector nhoff = 0x0001000d (u16 overflow)
...
skb linear: 00000000: 00 a0 c9 00 00 00 00 a0 c9 00 00 00 88
skb frag: 00000000: f7 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff
Using the size of the ptp_header struct will allow the corrected
calculation of the nhoff value.
net/core flow dissector nhoff = 0x0000000e
net/core flow dissector nhoff = 0x00000030 (sizeof ptp_header)

netfilter: nf_tables: Fix entries val in rule reset audit log
The value in idx and the number of rules handled in that particular
__nf_tables_dump_rules() call is not identical. The former is a cursor
to pick up from if multiple netlink messages are needed, so its value is
ever increasing. Fixing this is not just a matter of subtracting s_idx
from it, though: When resetting rules in multiple chains,
__nf_tables_dump_rules() is called for each and cb->args[0] is not
adjusted in between. Introduce a dedicated counter to record the number
of rules reset in this call in a less confusing way.
While being at it, prevent the direct return upon buffer exhaustion: Any
rules previously dumped into that skb would evade audit logging
otherwise.

NFSv4.1: fix pnfs MDS=DS session trunking
Currently, when GETDEVICEINFO returns multiple locations where each
is a different IP but the server's identity is same as MDS, then
nfs4_set_ds_client() finds the existing nfs_client structure which
has the MDS's max_connect value (and if it's 1), then the 1st IP
on the DS's list will get dropped due to MDS trunking rules. Other
IPs would be added as they fall under the pnfs trunking rules.
For the list of IPs the 1st goes thru calling nfs4_set_ds_client()
which will eventually call nfs4_add_trunk() and call into
rpc_clnt_test_and_add_xprt() which has the check for MDS trunking.
The other IPs (after the 1st one), would call rpc_clnt_add_xprt()
which doesn't go thru that check.
nfs4_add_trunk() is called when MDS trunking is happening and it
needs to enforce the usage of max_connect mount option of the
1st mount. However, this shouldn't be applied to pnfs flow.
Instead, this patch proposed to treat MDS=DS as DS trunking and
make sure that MDS's max_connect limit does not apply to the
1st IP returned in the GETDEVICEINFO list. It does so by
marking the newly created client with a new flag NFS_CS_PNFS
which then used to pass max_connect value to use into the
rpc_clnt_test_and_add_xprt() instead of the existing rpc
client's max_connect value set by the MDS connection.
For example, mount was done without max_connect value set
so MDS's rpc client has cl_max_connect=1. Upon calling into
rpc_clnt_test_and_add_xprt() and using rpc client's value,
the caller passes in max_connect value which is previously
been set in the pnfs path (as a part of handling
GETDEVICEINFO list of IPs) in nfs4_set_ds_client().
However, when NFS_CS_PNFS flag is not set and we know we
are doing MDS trunking, comparing a new IP of the same
server, we then set the max_connect value to the
existing MDS's value and pass that into
rpc_clnt_test_and_add_xprt().

tcp: Fix bind() regression for v4-mapped-v6 non-wildcard address.
Since bhash2 was introduced, the example below does not work as expected.
These two bind() should conflict, but the 2nd bind() now succeeds.
from socket import *
s1 = socket(AF_INET6, SOCK_STREAM)
s1.bind(('::ffff:127.0.0.1', 0))
s2 = socket(AF_INET, SOCK_STREAM)
s2.bind(('127.0.0.1', s1.getsockname()[1]))
During the 2nd bind() in inet_csk_get_port(), inet_bind2_bucket_find()
fails to find the 1st socket's tb2, so inet_bind2_bucket_create() allocates
a new tb2 for the 2nd socket. Then, we call inet_csk_bind_conflict() that
checks conflicts in the new tb2 by inet_bhash2_conflict(). However, the
new tb2 does not include the 1st socket, thus the bind() finally succeeds.
In this case, inet_bind2_bucket_match() must check if AF_INET6 tb2 has
the conflicting v4-mapped-v6 address so that inet_bind2_bucket_find()
returns the 1st socket's tb2.
Note that if we bind two sockets to 127.0.0.1 and then ::FFFF:127.0.0.1,
the 2nd bind() fails properly for the same reason mentinoed in the previous
commit.

tcp: Fix bind() regression for v4-mapped-v6 wildcard address.
Andrei Vagin reported bind() regression with strace logs.
If we bind() a TCPv6 socket to ::FFFF:0.0.0.0 and then bind() a TCPv4
socket to 127.0.0.1, the 2nd bind() should fail but now succeeds.
from socket import *
s1 = socket(AF_INET6, SOCK_STREAM)
s1.bind(('::ffff:0.0.0.0', 0))
s2 = socket(AF_INET, SOCK_STREAM)
s2.bind(('127.0.0.1', s1.getsockname()[1]))
During the 2nd bind(), if tb->family is AF_INET6 and sk->sk_family is
AF_INET in inet_bind2_bucket_match_addr_any(), we still need to check
if tb has the v4-mapped-v6 wildcard address.
The example above does not work after commit

This is because the value of rec_seq of tls_crypto_info configured by the
user program is too large, for example, 0xffffffffffffff. In addition, TLS
is asynchronously accelerated. When tls_do_encryption() returns
-EINPROGRESS and sk->sk_err is set to EBADMSG due to rec_seq overflow,
skmsg is released before the asynchronous encryption process ends. As a
result, the UAF problem occurs during the asynchronous processing of the
encryption module.
If the operation is asynchronous and the encryption module returns
EINPROGRESS, do not free the record information.

In kcm_sendmsg(), kcm_tx_msg(head)->last_skb is used as a cursor to append
newly allocated skbs to 'head'. If some bytes are copied, an error occurred,
and jumped to out_error label, 'last_skb' is left unmodified. A later
kcm_sendmsg() will use an obsoleted 'last_skb' reference, corrupting the
'head' frag_list and causing the leak.
This patch fixes this issue by properly updating the last allocated skb in
'last_skb'.

net: ipv4: fix one memleak in __inet_del_ifa()
I got the below warning when do fuzzing test:
unregister_netdevice: waiting for bond0 to become free. Usage count = 2
It can be repoduced via:
ip link add bond0 type bond
sysctl -w net.ipv4.conf.bond0.promote_secondaries=1
ip addr add 4.117.174.103/0 scope 0x40 dev bond0

ip addr add 0.0.0.4/0 scope 0x40 secondary dev bond0
ip addr del 4.117.174.103/0 scope 0x40 dev bond0
ip link delete bond0 type bond
In this reproduction test case, an incorrect 'last_prim' is found in
__inet_del_ifa(), as a result, the secondary address(0.0.0.4/0 scope 0x40)
is lost. The memory of the secondary address is leaked and the reference of
in_device and net_device is leaked.
Fix this problem:
Look for 'last_prim' starting at location of the deleted IP and inserting
the promoted IP into the location of 'last_prim'.

netfilter: nft_set_hash: try later when GC hits EAGAIN on iteration
Skip GC run if iterator rewinds to the beginning with EAGAIN, otherwise GC
might collect the same element more than once.

netfilter: nft_set_pipapo: stop GC iteration if GC transaction allocation fails
nft_trans_gc_queue_sync() enqueues the GC transaction and it allocates a
new one. If this allocation fails, then stop this GC sync run and retry
later.

netfilter: nft_set_pipapo: call nft_trans_gc_queue_sync() in catchall GC
pipapo needs to enqueue GC transactions for catchall elements through nft_trans_gc_queue_sync(). Add nft_trans_gc_catchall_sync() and nft_trans_gc_catchall_async() to handle GC transaction queueing accordingly. Fixes: |

netfilter: nft_set_rbtree: use read spinlock to avoid datapath contention
rbtree GC does not modify the datastructure, instead it collects expired
elements and it enqueues a GC transaction. Use a read spinlock instead
to avoid data contention while GC worker is running.

netfilter: nf_tables: disallow rule removal from chain binding
Chain binding only requires the rule addition/insertion command within the same transaction. Removal of rules from chain bindings within the same transaction makes no sense, userspace does not utilize this feature. Replace nft_chain_is_bound() check to nft_chain_binding() in rule deletion commands. Replace command implies a rule deletion, reject this command too. Rule flush command can also safely rely on this nft_chain_binding() check because unbound chains are not allowed since |

This time almost all fixes are for old bugs: First patch fixes a 4-byte stack OOB write, from myself. This was broken ever since nftables was switches from 128 to 32bit register addressing in v4.1. 2nd patch fixes an out-of-bounds read. This has been broken ever since xt_osf got added in 2.6.31, the bug was then just moved around during refactoring, from Wander Lairson Costa. 3rd patch adds a missing enum description, from Phil Sutter. 4th patch fixes a UaF inftables that occurs when userspace adds elements with a timeout so small that expiration happens while the transaction is still in progress. Fix from Pablo Neira Ayuso. Patch 5 fixes a memory out of bounds access, this was broken since v4.20. Patch from Kyle Zeng and Jozsef Kadlecsik. Patch 6 fixes another bogus memory access when building audit record.

Mixed with some fixes and cleanups, this brings in reasonably complete
fscrypt support to CephFS! The list of things which don't work with encryption should be fairly short, mostly around the edges: fallocate (not supported well in CephFS to begin with), copy_file_range (requires re-encryption), non-default striping patterns. This was a multi-year effort principally by Jeff Layton with assistance from Xiubo Li, Luís Henriques and others, including several dependant changes in the MDS, netfs helper library and fscrypt framework itself. -----BEGIN PGP SIGNATURE----- iQFHBAABCAAxFiEEydHwtzie9C7TfviiSn/eOAIR84sFAmT4pl4THGlkcnlvbW92 QGdtYWlsLmNvbQAKCRBKf944AhHzi5kzB/4sMgzZyUa3T1vA/G2pPvEkyy1qDxsW y+o4dDMWA9twcrBVpNuGd54wbXpmO/LAekHEdorjayH+f0zf10MsnP1ePz9WB3NG jr7RRujb+Gpd2OFYJXGSEbd3faTg8M2kpGCCrVe7SFNoyu8z9NwFItwWMog5aBjX ODGQrq+kA4ARA6xIqwzF5gP0zr+baT9rWhQdm7Xo9itWdosnbyDLJx1dpEfLuqBX te3SmifDzedn3Gw73hdNo/+ybw0kHARoK+RmXCTsoDDQw+JsoO9KxZF5Q8QcDELq 2woPNp0Hl+Dm4MkzGnPxv56Qj8ZDViS59syXC0CfGRmu4nzF1Rw+0qn5 =/WlE -----END PGP SIGNATURE----- Merge tag 'ceph-for-6.6-rc1' of https://github.com/ceph/ceph-client Pull ceph updates from Ilya Dryomov: "Mixed with some fixes and cleanups, this brings in reasonably complete fscrypt support to CephFS!
