e3e6940 Kent Overstreet31 August 2024, 21:44:51 UTCbcachefs: Revert lockless buffered IO path We had a report of data corruption on nixos when building installer images. https://github.com/NixOS/nixpkgs/pull/321055#issuecomment-2184131334 It seems that writes are being dropped, but only when issued by QEMU, and possibly only in snapshot mode. It's undetermined if it's write calls are being dropped or dirty folios. Further testing, via minimizing the original patch to just the change that skips the inode lock on non appends/truncates, reveals that it really is just not taking the inode lock that causes the corruption: it has nothing to do with the other logic changes for preserving write atomicity in corner cases. It's also kernel config dependent: it doesn't reproduce with the minimal kernel config that ktest uses, but it does reproduce with nixos's distro config. Bisection the kernel config initially pointer the finger at page migration or compaction, but it appears that was erroneous; we haven't yet determined what kernel config option actually triggers it. Sadly it appears this will have to be reverted since we're getting too close to release and my plate is full, but we'd _really_ like to fully debug it. My suspicion is that this patch is exposing a preexisting bug - the inode lock actually covers very little in IO paths, and we have a different lock (the pagecache add lock) that guards against races with truncate here.

1c47c0d Jens Axboe28 August 2024, 15:42:33 UTCio_uring/rsrc: ensure compat iovecs are copied correctly For buffer registration (or updates), a userspace iovec is copied in and updated. If the application is within a compat syscall, then the iovec type is compat_iovec rather than iovec. However, the type used in __io_sqe_buffers_update() and io_sqe_buffers_register() is always struct iovec, and hence the source is incremented by the size of a non-compat iovec in the loop. This misses every other iovec in the source, and will run into garbage half way through the copies and return -EFAULT to the application. Maintain the source address separately and assign to our user vec pointer, so that copies always happen from the right source address. While in there, correct a bad placement of __user which triggered the following sparse warning prior to this fix: io_uring/rsrc.c:981:33: warning: cast removes address space '__user' of expression io_uring/rsrc.c:981:30: warning: incorrect type in assignment (different address spaces) io_uring/rsrc.c:981:30: expected struct iovec const [noderef] __user *uvec io_uring/rsrc.c:981:30: got struct iovec *[noderef] __user Fixes: f4eaf8eda89e ("io_uring/rsrc: Drop io_copy_iov in favor of iovec API") Reviewed-by: Gabriel Krisman Bertazi <krisman@suse.de> Signed-off-by: Jens Axboe <axboe@kernel.dk>30 August 2024, 13:52:43 UTC

04c8aba Stephen Brennan29 August 2024, 18:20:49 UTCdcache: keep dentry_hashtable or d_hash_shift even when not used The runtime constant feature removes all the users of these variables, allowing the compiler to optimize them away. It's quite difficult to extract their values from the kernel text, and the memory saved by removing them is tiny, and it was never the point of this optimization. Since the dentry_hashtable is a core data structure, it's valuable for debugging tools to be able to read it easily. For instance, scripts built on drgn, like the dentrycache script[1], rely on it to be able to perform diagnostics on the contents of the dcache. Annotate it as used, so the compiler doesn't discard it.

Unfortunately without it nobody signals wakeup for the waiting process, and each "extended" command was timing out. But the rest of the code simply did not notice it. Fix this by switching from homegrown way of sending request to get command response and reading it to standard ps2_command() which does the right thing.

febccb3 Aleksandr Mishin27 August 2024, 08:48:22 UTCnfc: pn533: Add poll mod list filling check In case of im_protocols value is 1 and tm_protocols value is 0 this combination successfully passes the check 'if (!im_protocols && !tm_protocols)' in the nfc_start_poll(). But then after pn533_poll_create_mod_list() call in pn533_start_poll() poll mod list will remain empty and dev->poll_mod_count will remain 0 which lead to division by zero. Normally no im protocol has value 1 in the mask, so this combination is not expected by driver. But these protocol values actually come from userspace via Netlink interface (NFC_CMD_START_POLL operation). So a broken or malicious program may pass a message containing a "bad" combination of protocol parameter values so that dev->poll_mod_count is not incremented inside pn533_poll_create_mod_list(), thus leading to division by zero. Call trace looks like: nfc_genl_start_poll() nfc_start_poll() ->start_poll() pn533_start_poll() Add poll mod list filling check. Found by Linux Verification Center (linuxtesting.org) with SVACE.

b666a65 Paolo Abeni29 August 2024, 08:39:52 UTCMerge branch 'mptcp-more-fixes-for-the-in-kernel-pm' Matthieu Baerts says: ==================== mptcp: more fixes for the in-kernel PM Here is a new batch of fixes for the MPTCP in-kernel path-manager: Patch 1 ensures the address ID is set to 0 when the path-manager sends an ADD_ADDR for the address of the initial subflow. The same fix is applied when a new subflow is created re-using this special address. A fix for v6.0. Patch 2 is similar, but for the case where an endpoint is removed: if this endpoint was used for the initial address, it is important to send a RM_ADDR with this ID set to 0, and look for existing subflows with the ID set to 0. A fix for v6.0 as well. Patch 3 validates the two previous patches. Patch 4 makes the PM selecting an "active" path to send an address notification in an ACK, instead of taking the first path in the list. A fix for v5.11. Patch 5 fixes skipping the establishment of a new subflow if a previous subflow using the same pair of addresses is being closed. A fix for v5.13. Patch 6 resets the ID linked to the initial subflow when the linked endpoint is re-added, possibly with a different ID. A fix for v6.0. Patch 7 validates the three previous patches. Patch 8 is a small fix for the MPTCP Join selftest, when being used with older subflows not supporting all MIB counters. A fix for a commit introduced in v6.4, but backported up to v5.10. Patch 9 avoids the PM to try to close the initial subflow multiple times, and increment counters while nothing happened. A fix for v5.10. Patch 10 stops incrementing local_addr_used and add_addr_accepted counters when dealing with the address ID 0, because these counters are not taking into account the initial subflow, and are then not decremented when the linked addresses are removed. A fix for v6.0. Patch 11 validates the previous patch. Patch 12 avoids the PM to send multiple SUB_CLOSED events for the initial subflow. A fix for v5.12. Patch 13 validates the previous patch. Patch 14 stops treating the ADD_ADDR 0 as a new address, and accepts it in order to re-create the initial subflow if it has been closed, even if the limit for *new* addresses -- not taking into account the address of the initial subflow -- has been reached. A fix for v5.10. Patch 15 validates the previous patch.

If the host receives it, it simply means that the address is available again. When receiving an ADD_ADDR for the ID 0, the PM already doesn't consider it as new by not incrementing the 'add_addr_accepted' counter. But the 'accept_addr' might not be set if the limit has already been reached: this can be bypassed in this case. But before, it is important to check that this ADD_ADDR for the ID 0 is for the same address as the initial subflow. If not, it is not something that should happen, and the ADD_ADDR can be ignored. Note that if an ADD_ADDR is received while there is already a subflow opened using the same address, this ADD_ADDR is ignored as well. It means that if multiple ADD_ADDR for ID 0 are received, there will not be any duplicated subflows created by the client.

When the worker is instructed to close the subflows that have been marked as closed, it might then try to close the initial subflow again. A consequence of that is that the SUB_CLOSED event can be seen twice: # ip mptcp endpoint 1.1.1.1 id 1 subflow dev eth0 2.2.2.2 id 2 subflow dev eth1 # ip mptcp monitor & [ CREATED] remid=0 locid=0 saddr4=1.1.1.1 daddr4=9.9.9.9 [ ESTABLISHED] remid=0 locid=0 saddr4=1.1.1.1 daddr4=9.9.9.9 [ SF_ESTABLISHED] remid=0 locid=2 saddr4=2.2.2.2 daddr4=9.9.9.9 # ip mptcp endpoint delete id 1 [ SF_CLOSED] remid=0 locid=0 saddr4=1.1.1.1 daddr4=9.9.9.9 [ SF_CLOSED] remid=0 locid=0 saddr4=1.1.1.1 daddr4=9.9.9.9 The first one is coming from mptcp_pm_nl_rm_subflow_received(), and the second one from __mptcp_close_subflow(). To avoid doing the post-closed processing twice, the subflow is now marked as closed the first time. Note that it is not enough to check if we are dealing with the first subflow and check its sk_state: the subflow might have been reset or closed before calling mptcp_close_ssk().

When a global endpoint is deleted and re-added later, it can have a different ID, but the kernel should still use the ID 0 if it corresponds to the initial address.

When a global endpoint is deleted and re-added later, it can have a different ID -- most services managing the endpoints automatically don't force the ID to be the same as before. It is then important to track these modifications to be consistent with the ID being used for the address used by the initial subflow, not to confuse the other peer or to send the ID 0 for the wrong address. Now when removing an endpoint, msk->mpc_endpoint_id is reset if it corresponds to this endpoint. When adding a new endpoint, the same variable is updated if the address match the one of the initial subflow.

But there could be a subflow that is closing, but taking time due to some reasons: latency, losses, data to process, etc. If an ADD_ADDR is received while the endpoint is being closed, it is better to try connecting to it, instead of rejecting it: the peer which has sent the ADD_ADDR will not be notified that the ADD_ADDR has been rejected for this reason, and the expected subflow will not be created at the end.

76a0e79 Scott Mayhew28 August 2024, 19:51:29 UTCselinux,smack: don't bypass permissions check in inode_setsecctx hook Marek Gresko reports that the root user on an NFS client is able to change the security labels on files on an NFS filesystem that is exported with root squashing enabled. The end of the kerneldoc comment for __vfs_setxattr_noperm() states: * This function requires the caller to lock the inode's i_mutex before it * is executed. It also assumes that the caller will make the appropriate * permission checks. nfsd_setattr() does do permissions checking via fh_verify() and nfsd_permission(), but those don't do all the same permissions checks that are done by security_inode_setxattr() and its related LSM hooks do. Since nfsd_setattr() is the only consumer of security_inode_setsecctx(), simplest solution appears to be to replace the call to __vfs_setxattr_noperm() with a call to __vfs_setxattr_locked(). This fixes the above issue and has the added benefit of causing nfsd to recall conflicting delegations on a file when a client tries to change its security label.

91d1dfa David Howells28 August 2024, 20:08:25 UTCcifs: Fix FALLOC_FL_ZERO_RANGE to preflush buffered part of target region Under certain conditions, the range to be cleared by FALLOC_FL_ZERO_RANGE may only be buffered locally and not yet have been flushed to the server. For example: xfs_io -f -t -c "pwrite -S 0x41 0 4k" \ -c "pwrite -S 0x42 4k 4k" \ -c "fzero 0 4k" \ -c "pread -v 0 8k" /xfstest.test/foo will write two 4KiB blocks of data, which get buffered in the pagecache, and then fallocate() is used to clear the first 4KiB block on the server - but we don't flush the data first, which means the EOF position on the server is wrong, and so the FSCTL_SET_ZERO_DATA RPC fails (and xfs_io ignores the error), but then when we try to read it, we see the old data. Fix this by preflushing any part of the target region that above the server's idea of the EOF position to force the server to update its EOF position. Note, however, that we don't want to simply expand the file by moving the EOF before doing the FSCTL_SET_ZERO_DATA[*] because someone else might see the zeroed region or if the RPC fails we then have to try to clean it up or risk getting corruption. [*] And we have to move the EOF first otherwise FSCTL_SET_ZERO_DATA won't do what we want. This fixes the generic/008 xfstest. [!] Note: A better way to do this might be to split the operation into two parts: we only do FSCTL_SET_ZERO_DATA for the part of the range below the server's EOF and then, if that worked, invalidate the buffered pages for the part above the range.

Wong27 August 2024, 17:53:40 UTCblock: fix detection of unsupported WRITE SAME in blkdev_issue_write_zeroes On error, blkdev_issue_write_zeroes used to recheck the block device's WRITE SAME queue limits after submitting WRITE SAME bios. As stated in the comment, the purpose of this was to collapse all IO errors to EOPNOTSUPP if the effect of issuing bios was that WRITE SAME got turned off in the queue limits. Therefore, it does not make sense to reuse the zeroes limit that was read earlier in the function because we only care about the queue limit *now*, not what it was at the start of the function.

1da29f2 David Howells22 August 2024, 22:06:49 UTCnetfs, cifs: Fix handling of short DIO read Short DIO reads, particularly in relation to cifs, are not being handled correctly by cifs and netfslib. This can be tested by doing a DIO read of a file where the size of read is larger than the size of the file. When it crosses the EOF, it gets a short read and this gets retried, and in the case of cifs, the retry read fails, with the failure being translated to ENODATA. Fix this by the following means: (1) Add a flag, NETFS_SREQ_HIT_EOF, for the filesystem to set when it detects that the read did hit the EOF. (2) Make the netfslib read assessment stop processing subrequests when it encounters one with that flag set. (3) Return rreq->transferred, the accumulated contiguous amount read to that point, to userspace for a DIO read. (4) Make cifs set the flag and clear the error if the read RPC returned ENODATA. (5) Make cifs set the flag and clear the error if a short read occurred without error and the read-to file position is now at the remote inode size.

6a5dcd4 David Howells22 August 2024, 22:06:48 UTCcifs: Fix lack of credit renegotiation on read retry When netfslib asks cifs to issue a read operation, it prefaces this with a call to ->clamp_length() which cifs uses to negotiate credits, providing receive capacity on the server; however, in the event that a read op needs reissuing, netfslib doesn't call ->clamp_length() again as that could shorten the subrequest, leaving a gap. This causes the retried read to be done with zero credits which causes the server to reject it with STATUS_INVALID_PARAMETER. This is a problem for a DIO read that is requested that would go over the EOF. The short read will be retried, causing EINVAL to be returned to the user when it fails. Fix this by making cifs_req_issue_read() negotiate new credits if retrying (NETFS_SREQ_RETRYING now gets set in the read side as well as the write side in this instance). This isn't sufficient, however: the new credits might not be sufficient to complete the remainder of the read, so also add an additional field, rreq->actual_len, that holds the actual size of the op we want to perform without having to alter subreq->len. We then rely on repeated short reads being retried until we finish the read or reach the end of file and make a zero-length read. Also fix a couple of places where the subrequest start and length need to be altered by the amount so far transferred when being used.

a2ccc33 Imre Deak23 August 2024, 16:29:18 UTCdrm/i915/dp_mst: Fix MST state after a sink reset In some cases the sink can reset itself after it was configured into MST mode, without the driver noticing the disconnected state. For instance the reset may happen in the middle of a modeset, or the (long) HPD pulse generated may be not long enough for the encoder detect handler to observe the HPD's deasserted state. In this case the sink's DPCD register programmed to enable MST will be reset, while the driver still assumes MST is still enabled. Detect this condition, which will tear down and recreate/re-enable the MST topology. v2: - Add a code comment about adjusting the expected DP_MSTM_CTRL register value for SST + SideBand. (Suraj, Jani) - Print a debug message about detecting the link reset. (Jani) - Verify the DPCD MST state only if it wasn't already determined that the sink is disconnected.

3a0504d Ondrej Mosnacek26 August 2024, 13:07:11 UTCsctp: fix association labeling in the duplicate COOKIE-ECHO case sctp_sf_do_5_2_4_dupcook() currently calls security_sctp_assoc_request() on new_asoc, but as it turns out, this association is always discarded and the LSM labels never get into the final association (asoc). This can be reproduced by having two SCTP endpoints try to initiate an association with each other at approximately the same time and then peel off the association into a new socket, which exposes the unitialized labels and triggers SELinux denials. Fix it by calling security_sctp_assoc_request() on asoc instead of new_asoc. Xin Long also suggested limit calling the hook only to cases A, B, and D, since in cases C and E the COOKIE ECHO chunk is discarded and the association doesn't enter the ESTABLISHED state, so rectify that as well. One related caveat with SELinux and peer labeling: When an SCTP connection is set up simultaneously in this way, we will end up with an association that is initialized with security_sctp_assoc_request() on both sides, so the MLS component of the security context of the association will get swapped between the peers, instead of just one side setting it to the other's MLS component.

Here are different fixes: Patch 1 closes the subflow after having received a FIN, instead of leaving it half-closed until the end of the MPTCP connection. A fix for v5.12. Patch 2 validates the previous patch. Patch 3 is a fix for a recent fix to check both directions for the backup flag. It can follow the 'Fixes' commit and be backported up to v5.7. Patch 4 adds a missing \n at the end of pr_debug(), causing debug messages to be displayed with a delay, which confuses the debugger. A fix for v5.6. ==================== Link: https://patch.msgid.link/20240826-net-mptcp-close-extra-sf-fin-v1-0-905199fe1172@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>27 August 2024, 21:45:18 UTC
cb41b19 Matthieu Baerts (NGI0)26 August 2024, 17:11:21 UTCmptcp: pr_debug: add missing \n at the end pr_debug() have been added in various places in MPTCP code to help developers to debug some situations. With the dynamic debug feature, it is easy to enable all or some of them, and asks users to reproduce issues with extra debug. Many of these pr_debug() don't end with a new line, while no 'pr_cont()' are used in MPTCP code. So the goal was not to display multiple debug messages on one line: they were then not missing the '\n' on purpose. Not having the new line at the end causes these messages to be printed with a delay, when something else needs to be printed. This issue is not visible when many messages need to be printed, but it is annoying and confusing when only specific messages are expected, e.g. # echo "func mptcp_pm_add_addr_echoed +fmp" \ > /sys/kernel/debug/dynamic_debug/control # ./mptcp_join.sh "signal address"; \ echo "$(awk '{print $1}' /proc/uptime) - end"; \ sleep 5s; \ echo "$(awk '{print $1}' /proc/uptime) - restart"; \ ./mptcp_join.sh "signal address" 013 signal address (...) 10.75 - end 15.76 - restart 013 signal address [ 10.367935] mptcp:mptcp_pm_add_addr_echoed: MPTCP: msk=(...) (...) => a delay of 5 seconds: printed with a 10.36 ts, but after 'restart' which was printed at the 15.76 ts. The 'Fixes' tag here below points to the first pr_debug() used without '\n' in net/mptcp. This patch could be split in many small ones, with different Fixes tag, but it doesn't seem worth it, because it is easy to re-generate this patch with this simple 'sed' command: git grep -l pr_debug -- net/mptcp | xargs sed -i "s/\(pr_debug(\".*[^n]\)\(\"[,)]\)/\1\\\n\2/g" So in case of conflicts, simply drop the modifications, and launch this command.

2a1f596 Matthieu Baerts (NGI0)26 August 2024, 17:11:20 UTCmptcp: sched: check both backup in retrans The 'mptcp_subflow_context' structure has two items related to the backup flags: - 'backup': the subflow has been marked as backup by the other peer - 'request_bkup': the backup flag has been set by the host Looking only at the 'backup' flag can make sense in some cases, but it is not the behaviour of the default packet scheduler when selecting paths. As explained in the commit b6a66e521a20 ("mptcp: sched: check both directions for backup"), the packet scheduler should look at both flags, because that was the behaviour from the beginning: the 'backup' flag was set by accident instead of the 'request_bkup' one. Now that the latter has been fixed, get_retrans() needs to be adapted as well.

e93681a Matthieu Baerts (NGI0)26 August 2024, 17:11:19 UTCselftests: mptcp: join: cannot rm sf if closed Thanks to the previous commit, the MPTCP subflows are now closed on both directions even when only the MPTCP path-manager of one peer asks for their closure. In the two tests modified here -- "userspace pm add & remove address" and "userspace pm create destroy subflow" -- one peer is controlled by the userspace PM, and the other one by the in-kernel PM. When the userspace PM sends a RM_ADDR notification, the in-kernel PM will automatically react by closing all subflows using this address. Now, thanks to the previous commit, the subflows are properly closed on both directions, the userspace PM can then no longer closes the same subflows if they are already closed. Before, it was OK to do that, because the subflows were still half-opened, still OK to send a RM_ADDR. In other words, thanks to the previous commit closing the subflows, an error will be returned to the userspace if it tries to close a subflow that has already been closed. So no need to run this command, which mean that the linked counters will then not be incremented. These tests are then no longer sending both a RM_ADDR, then closing the linked subflow just after. The test with the userspace PM on the server side is now removing one subflow linked to one address, then sending a RM_ADDR for another address. The test with the userspace PM on the client side is now only removing the subflow that was previously created.

f09b0ad Matthieu Baerts (NGI0)26 August 2024, 17:11:18 UTCmptcp: close subflow when receiving TCP+FIN When a peer decides to close one subflow in the middle of a connection having multiple subflows, the receiver of the first FIN should accept that, and close the subflow on its side as well. If not, the subflow will stay half closed, and would even continue to be used until the end of the MPTCP connection or a reset from the network. The issue has not been seen before, probably because the in-kernel path-manager always sends a RM_ADDR before closing the subflow. Upon the reception of this RM_ADDR, the other peer will initiate the closure on its side as well. On the other hand, if the RM_ADDR is lost, or if the path-manager of the other peer only closes the subflow without sending a RM_ADDR, the subflow would switch to TCP_CLOSE_WAIT, but that's it, leaving the subflow half-closed. So now, when the subflow switches to the TCP_CLOSE_WAIT state, and if the MPTCP connection has not been closed before with a DATA_FIN, the kernel owning the subflow schedules its worker to initiate the closure on its side as well. This issue can be easily reproduced with packetdrill, as visible in [1], by creating an additional subflow, injecting a FIN+ACK before sending the DATA_FIN, and expecting a FIN+ACK in return.

bac76cf Xueming Feng26 August 2024, 10:23:27 UTCtcp: fix forever orphan socket caused by tcp_abort We have some problem closing zero-window fin-wait-1 tcp sockets in our environment. This patch come from the investigation. Previously tcp_abort only sends out reset and calls tcp_done when the socket is not SOCK_DEAD, aka orphan. For orphan socket, it will only purging the write queue, but not close the socket and left it to the timer. While purging the write queue, tp->packets_out and sk->sk_write_queue is cleared along the way. However tcp_retransmit_timer have early return based on !tp->packets_out and tcp_probe_timer have early return based on !sk->sk_write_queue. This caused ICSK_TIME_RETRANS and ICSK_TIME_PROBE0 not being resched and socket not being killed by the timers, converting a zero-windowed orphan into a forever orphan. This patch removes the SOCK_DEAD check in tcp_abort, making it send reset to peer and close the socket accordingly. Preventing the timer-less orphan from happening. According to Lorenzo's email in the v1 thread, the check was there to prevent force-closing the same socket twice. That situation is handled by testing for TCP_CLOSE inside lock, and returning -ENOENT if it is already closed. The -ENOENT code comes from the associate patch Lorenzo made for iproute2-ss; link attached below, which also conform to RFC 9293. At the end of the patch, tcp_write_queue_purge(sk) is removed because it was already called in tcp_done_with_error(). p.s. This is the same patch with v2. Resent due to mis-labeled "changes requested" on patchwork.kernel.org.
