bpf: Fix max stack depth check for async callbacks
The check_max_stack_depth pass happens after the verifier's symbolic
execution, and attempts to walk the call graph of the BPF program,
ensuring that the stack usage stays within bounds for all possible call
chains. There are two cases to consider: bpf_pseudo_func and
bpf_pseudo_call. In the former case, the callback pointer is loaded into
a register, and is assumed that it is passed to some helper later which
calls it (however there is no way to be sure), but the check remains
conservative and accounts the stack usage anyway. For this particular
case, asynchronous callbacks are skipped as they execute asynchronously
when their corresponding event fires.
The case of bpf_pseudo_call is simpler and we know that the call is
definitely made, hence the stack depth of the subprog is accounted for.
However, the current check still skips an asynchronous callback even if
a bpf_pseudo_call was made for it. This is erroneous, as it will miss
accounting for the stack usage of the asynchronous callback, which can
be used to breach the maximum stack depth limit.
Fix this by only skipping asynchronous callbacks when the instruction is
not a pseudo call to the subprog.

f2fs update for 6.5-rc1
In this cycle, we've mainly investigated the zoned block device support along
with patches such as correcting write pointers between f2fs and storage, adding
asynchronous zone reset flow, and managing the number of open zones. Other than
them, f2fs adds another mount option, "errors=x" to specify how to handle when
it detects an unexpected behavior at runtime.
Enhancement:
- support errors=remount-ro|continue|panic mountoption
- enforce some inode flag policies
- allow .tmp compression given extensions
- add some ioctls to manage the f2fs compression
- improve looped node chain flow
- avoid issuing small-sized discard commands during checkpoint
- implement an asynchronous zone reset
Bug fix:
- fix deadlock in xattr and inode page lock
- fix and add sanity check in some error paths
- fix to avoid NULL pointer dereference f2fs_write_end_io() along with put_super
- set proper flags to quota files
- fix potential deadlock due to unpaired node_write lock use
- fix over-estimating free section during FG GC
- fix the wrong condition to determine atomic context
As usual, also there are a number of patches having code refactoring and minor
clean-ups.

nfp: clean mc addresses in application firmware when closing port
When moving devices from one namespace to another, mc addresses are
cleaned in software while not removed from application firmware. Thus
the mc addresses are remained and will cause resource leak.
Now use `__dev_mc_unsync` to clean mc addresses when closing port.

Merge branch 'mptcp-fixes'
Matthieu Baerts says: ==================== mptcp: fixes for v6.5 Here is a first batch of fixes for v6.5 and older. The fixes are not linked to each others. Patch 1 ensures subflows are unhashed before cleaning the backlog to avoid races. This fixes another recent fix from v6.4. Patch 2 does not rely on implicit state check in mptcp_listen() to avoid races when receiving an MP_FASTCLOSE. A regression from v5.17. The rest fixes issues in the selftests. Patch 3 makes sure errors when setting up the environment are no longer ignored. For v5.17+. Patch 4 uses 'iptables-legacy' if available to be able to run on older kernels. A fix for v5.13 and newer. Patch 5 catches errors when issues are detected with packet marks. Also for v5.13+. Patch 6 uses the correct variable instead of an undefined one. Even if there was no visible impact, it can help to find regressions later. An issue visible in v5.19+. Patch 7 makes sure errors with some sub-tests are reported to have the selftest marked as failed as expected. Also for v5.19+. Patch 8 adds a kernel config that is required to execute MPTCP selftests. It is valid for v5.9+. Patch 9 fixes issues when validating the userspace path-manager with 32-bit arch, an issue affecting v5.19+. ==================== Signed-off-by: Matthieu Baerts <matthieu.baerts@tessares.net> |

selftests: mptcp: pm_nl_ctl: fix 32-bit support
When using pm_nl_ctl to validate userspace path-manager's behaviours, it was failing on 32-bit architectures ~half of the time. pm_nl_ctl was not reporting any error but the command was not doing what it was expected to do. As a result, the expected linked event was not triggered after and the test failed. This is due to the fact the token given in argument to the application was parsed as an integer with atoi(): in a 32-bit arch, if the number was bigger than INT_MAX, 2147483647 was used instead. This can simply be fixed by using strtoul() instead of atoi(). The errors have been seen "by chance" when manually looking at the results from LKFT. Fixes: |

selftests: mptcp: depend on SYN_COOKIES
MPTCP selftests are using TCP SYN Cookies for quite a while now, since
v5.9.
Some CIs don't have this config option enabled and this is causing
issues in the tests:
# ns1 MPTCP -> ns1 (10.0.1.1:10000 ) MPTCP (duration 167ms) sysctl: cannot stat /proc/sys/net/ipv4/tcp_syncookies: No such file or directory
# [ OK ]./mptcp_connect.sh: line 554: [: -eq: unary operator expected
There is no impact in the results but the test is not doing what it is
supposed to do.

Now the 'ret' variable is directly set to 1 in order to make sure the

selftests: mptcp: connect: fail if nft supposed to work
In case of "external" errors when preparing the environment for the
TProxy tests, the subtests were marked as skipped.
This is fine but it means these errors are ignored. On MPTCP Public CI,
we do want to catch such issues and mark the selftest as failed if there
are such issues. We can then use mptcp_lib_fail_if_expected_feature()
helper that has been recently added to fail if needed.

mptcp: do not rely on implicit state check in mptcp_listen()
Since the blamed commit, closing the first subflow resets the first
subflow socket state to SS_UNCONNECTED.
The current mptcp listen implementation relies only on such
state to prevent touching not-fully-disconnected sockets.
Incoming mptcp fastclose (or paired endpoint removal) unconditionally
closes the first subflow.
All the above allows an incoming fastclose followed by a listen() call
to successfully race with a blocking recvmsg(), potentially causing the
latter to hit a divide by zero bug in cleanup_rbuf/__tcp_select_window().
Address the issue explicitly checking the msk socket state in
mptcp_listen(). An alternative solution would be moving the first
subflow socket state update into mptcp_disconnect(), but in the long
term the first subflow socket should be removed: better avoid relaying
on it for internal consistency check.

afs: Fix accidental truncation when storing data
When an AFS FS.StoreData RPC call is made, amongst other things it is
given the resultant file size to be. On the server, this is processed
by truncating the file to new size and then writing the data.
Now, kafs has a lock (vnode->io_lock) that serves to serialise
operations against a specific vnode (ie. inode), but the parameters for
the op are set before the lock is taken. This allows two writebacks
(say sync and kswapd) to race - and if writes are ongoing the writeback
for a later write could occur before the writeback for an earlier one if
the latter gets interrupted.
Note that afs_writepages() cannot take i_mutex and only takes a shared
lock on vnode->validate_lock.
Also note that the server does the truncation and the write inside a
lock, so there's no problem at that end.
Fix this by moving the calculation for the proposed new i_size inside
the vnode->io_lock. Also reset the iterator (which we might have read
from) and update the mtime setting there.

Vladimir Oltean says: ==================== dsa: Fix mangled link-local MAC DAs with SJA1105 DSA The SJA1105 hardware tagging protocol is weird and will put DSA information (source port, switch ID) in the MAC DA of the packets sent to the CPU, and then send some additional (meta) packets which contain the original bytes from the previous packet's MAC DA. The tagging protocol driver contains logic to handle this, but the meta frames are optional functionality, and there are configurations when they aren't received (no PTP RX timestamping). Thus, the MAC DA from packets sent to the stack is not correct in all cases. Also, during testing it was found that the MAC DA patching procedure was incorrect. The investigation comes as a result of this discussion with Paolo: https://lore.kernel.org/netdev/f494387c8d55d9b1d5a3e88beedeeb448f2e6cc3.camel@redhat.com/ ==================== Signed-off-by: David S.

net: dsa: tag_sja1105: fix MAC DA patching from meta frames
The SJA1105 manual says that at offset 4 into the meta frame payload we
have "MAC destination byte 2" and at offset 5 we have "MAC destination
byte 1". These are counted from the LSB, so byte 1 is h_dest[ETH_HLEN-2]
aka h_dest[4] and byte 2 is h_dest[ETH_HLEN-3] aka h_dest[3].
The sja1105_meta_unpack() function decodes these the other way around,
so a frame with MAC DA 01:80:c2:11:22:33 is received by the network
stack as having 01:80:c2:22:11:33.

net: Replace strlcpy with strscpy
strlcpy() reads the entire source buffer first. This read may exceed the destination size limit. This is both inefficient and can lead to linear read overflows if a source string is not NUL-terminated [1]. In an effort to remove strlcpy() completely [2], replace strlcpy() here with strscpy(). No return values were used, so direct replacement is safe.

pptp: Fix fib lookup calls.
PPTP uses pppox sockets (struct pppox_sock). These sockets don't embed
an inet_sock structure, so it's invalid to call inet_sk() on them.
Therefore, the ip_route_output_ports() call in pptp_connect() has two
problems:
* The tos variable is set with RT_CONN_FLAGS(sk), which calls
inet_sk() on the pppox socket.
* ip_route_output_ports() tries to retrieve routing flags using
inet_sk_flowi_flags(), which is also going to call inet_sk() on the
pppox socket.
While PPTP doesn't use inet sockets, it's actually really layered on
top of IP and therefore needs a proper way to do fib lookups. So let's
define pptp_route_output() to get a struct rtable from a pptp socket.
Let's also replace the ip_route_output_ports() call of pptp_xmit() for
consistency.
In practice, this means that:
* pptp_connect() sets ->flowi4_tos and ->flowi4_flags to zero instead
of using bits of unrelated struct pppox_sock fields.
* pptp_xmit() now respects ->sk_mark and ->sk_uid.
* pptp_xmit() now calls the security_sk_classify_flow() security
hook, thus allowing to set ->flowic_secid.
* pptp_xmit() now passes the pppox socket to xfrm_lookup_route().
Found by code inspection.

This change adds new events to the UAPI, allowing applications to retrieve the time when asynchronous packet are received and sent. The new events are tested in the breeding edge of libhinawa and look to work well.

module: fix init_module_from_file() error handling
Vegard Nossum pointed out two different problems with the error handling
in init_module_from_file():
(a) the idempotent loading code didn't clean up properly in some error
cases, leaving the on-stack 'struct idempotent' element still in
the hash table
(b) failure to read the module file would nonsensically update the
'invalid_kread_bytes' stat counter with the error value
The first error is quite nasty, in that it can then cause subsequent
idempotent loads of that same file to access stale stack contents of the
previous failure. The case may not happen in any normal situation
(explaining all the "Tested-by's on the original change), and requires
admin privileges, but syzkaller triggers random bad behavior as a
result:
BUG: soft lockup in sys_finit_module
BUG: unable to handle kernel paging request in init_module_from_file
general protection fault in init_module_from_file
INFO: task hung in init_module_from_file
KASAN: out-of-bounds Read in init_module_from_file
KASAN: slab-out-of-bounds Read in init_module_from_file
...
The second error is fairly benign and just leads to nonsensical stats
(and has been around since the debug stats were added).
Vegard also provided a patch for the idempotent loading issue, but I'd
rather re-organize the code and make it more legible using another level
of helper functions than add the usual "goto out" error handling.

smaller than the intended sizeof(struct tc_pedit). Hence, the
dereference in tcf_pedit_init() could access dirty heap data.
static int tcf_pedit_init(...)
{
// ...
pattr = tb[TCA_PEDIT_PARMS]; // TCA_PEDIT_PARMS is included
if (!pattr)
pattr = tb[TCA_PEDIT_PARMS_EX]; // but this is not
// ...
parm = nla_data(pattr);
index = parm->index; // parm is able to be smaller than 4 bytes
// and this dereference gets dirty skb_buff
// data created in netlink_sendmsg
}
This commit adds TCA_PEDIT_PARMS_EX length in pedit_policy which avoid
the above case, just like the TCA_PEDIT_PARMS.

xsk: Honor SO_BINDTODEVICE on bind
Initial creation of an AF_XDP socket requires CAP_NET_RAW capability. A
privileged process might create the socket and pass it to a non-privileged
process for later use. However, that process will be able to bind the socket
to any network interface. Even though it will not be able to receive any
traffic without modification of the BPF map, the situation is not ideal.
Sockets already have a mechanism that can be used to restrict what interface
they can be attached to. That is SO_BINDTODEVICE.
To change the SO_BINDTODEVICE binding the process will need CAP_NET_RAW.
Make xsk_bind() honor the SO_BINDTODEVICE in order to allow safer workflow
when non-privileged process is using AF_XDP.
The intended workflow is following:
1. First process creates a bare socket with socket(AF_XDP, ...).
2. First process loads the XSK program to the interface.
3. First process adds the socket fd to a BPF map.
4. First process ties socket fd to a particular interface using
SO_BINDTODEVICE.
5. First process sends socket fd to a second process.
6. Second process allocates UMEM.
7. Second process binds socket to the interface with bind(...).
8. Second process sends/receives the traffic.
All the steps above are possible today if the first process is privileged
and the second one has sufficient RLIMIT_MEMLOCK and no capabilities.
However, the second process will be able to bind the socket to any interface
it wants on step 7 and send traffic from it. With the proposed change, the
second process will be able to bind the socket only to a specific interface
chosen by the first process at step 4.
