Pull f2fs updates from Jaegeuk Kim: "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. Enhancements: - support 'errors=remount-ro|continue|panic' mount option - 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 fixes: - 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 with code refactoring and minor clean-ups" * tag 'f2fs-for-6.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs: (46 commits) f2fs: fix to do sanity check on direct node in truncate_dnode() f2fs: only set release for file that has compressed data f2fs: fix compile warning in f2fs_destroy_node_manager() f2fs: fix error path handling in truncate_dnode() f2fs: fix deadlock in i_xattr_sem and inode page lock f2fs: remove unneeded page uptodate check/set f2fs: update mtime and ctime in move file range method f2fs: compress tmp files given extension f2fs: refactor struct f2fs_attr macro f2fs: convert to use sbi directly f2fs: remove redundant assignment to variable err f2fs: do not issue small discard commands during checkpoint f2fs: check zone write pointer points to the end of zone f2fs: add f2fs_ioc_get_compress_blocks f2fs: cleanup MIN_INLINE_XATTR_SIZE f2fs: add helper to check compression level f2fs: set FMODE_CAN_ODIRECT instead of a dummy direct_IO method f2fs: do more sanity check on inode f2fs: compress: fix to check validity of i_compress_flag field f2fs: add sanity compress level check for compressed file ... -

I added a warning about about GUP no longer expanding the stack in commit a425ac53 ("gup: add warning if some caller would seem to want stack expansion"), but didn't really expect anybody to hit it. And it's true that nobody seems to have hit a _real_ case yet, but we certainly have a number of reports of false positives. Which not only causes extra noise in itself, but might also end up hiding any real cases if they do exist. So let's tighten up the warning condition, and replace the simplistic vma = find_vma(mm, start); if (vma && (start < vma->vm_start)) { WARN_ON_ONCE(vma->vm_flags & VM_GROWSDOWN); with a vma = gup_vma_lookup(mm, start); helper function which works otherwise like just "vma_lookup()", but with some heuristics for when to warn about gup no longer causing stack expansion. In particular, don't just warn for "below the stack", but warn if it's _just_ below the stack (with "just below" arbitrarily defined as 64kB, because why not?). And rate-limit it to at most once per hour, which means that any false positives shouldn't completely hide subsequent reports, but we won't be flooding the logs about it either. The previous code triggered when some GUP user (chromium crashpad) accessing past the end of the previous vma, for example. That has never expanded the stack, it just causes GUP to return early, and as such we shouldn't be warning about it. This is still going trigger the randomized testers, but to mitigate the noise from that, use "dump_stack()" instead of "WARN_ON_ONCE()" to get the kernel call chain. We'll get the relevant information, but syzbot shouldn't get too upset about it. Also, don't even bother with the GROWSUP case, which would be using different heuristics entirely, but only happens on parisc. Reported-by:

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>

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.

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.

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.

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. Fixes: bd80d8a8 ("afs: Use ITER_XARRAY for writing") Reported-by:

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:

incl_srcpt has the limitation, mentioned in commit b4638af8 ("net: dsa: sja1105: always enable the INCL_SRCPT option"), that frames with a MAC DA of 01:80:c2:xx:yy:zz will be received as 01:80:c2:00:00:zz unless PTP RX timestamping is enabled. The incl_srcpt option was initially unconditionally enabled, then that changed with commit 42824463 ("net: dsa: sja1105: Limit use of incl_srcpt to bridge+vlan mode"), then again with b4638af8 ("net: dsa: sja1105: always enable the INCL_SRCPT option"). Bottom line is that it now needs to be always enabled, otherwise the driver does not have a reliable source of information regarding source_port and switch_id for link-local traffic (tag_8021q VLANs may be imprecise since now they identify an entire bridging domain when ports are not standalone). If we accept that PTP RX timestamping (and therefore, meta frame generation) is always enabled in hardware, then that limitation could be avoided and packets with any MAC DA can be properly received, because meta frames do contain the original bytes from the MAC DA of their associated link-local packet. This change enables meta frame generation unconditionally, which also has the nice side effects of simplifying the switch control path (a switch reset is no longer required on hwtstamping settings change) and the tagger data path (it no longer needs to be informed whether to expect meta frames or not - it always does).

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.

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. [1] https://www.kernel.org/doc/html/latest/process/deprecated.html#strlcpy [2] https://github.com/KSPP/linux/issues/89Signed-off-by:

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().
