2024-06-26nvmet-fc: Remove __counted_by from nvmet_fc_tgt_queue.fod[]Nathan Chancellor
Work for __counted_by on generic pointers in structures (not just flexible array members) has started landing in Clang 19 (current tip of tree). During the development of this feature, a restriction was added to __counted_by to prevent the flexible array member's element type from including a flexible array member itself such as: struct foo { int count; char buf[]; }; struct bar { int count; struct foo data[] __counted_by(count); }; because the size of data cannot be calculated with the standard array size formula: sizeof(struct foo) * count This restriction was downgraded to a warning but due to CONFIG_WERROR, it can still break the build. The application of __counted_by on the fod member of 'struct nvmet_fc_tgt_queue' triggers this restriction, resulting in: drivers/nvme/target/fc.c:151:2: error: 'counted_by' should not be applied to an array with element of unknown size because 'struct nvmet_fc_fcp_iod' is a struct type with a flexible array member. This will be an error in a future compiler version [-Werror,-Wbounds-safety-counted-by-elt-type-unknown-size] 151 | struct nvmet_fc_fcp_iod fod[] __counted_by(sqsize); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 1 error generated. Remove this use of __counted_by to fix the warning/error. However, rather than remove it altogether, leave it commented, as it may be possible to support this in future compiler releases.

2024-06-26gpu: ipu-v3: pre: don't use fixed timeout when waiting for safe windowLucas Stach
The timeout when waiting for the PRE safe window is rather short, as normally we would only need to wait a few dozen usecs for the problematic scanline region to pass and we don't want to spin too long in case something goes wrong. This however mixes badly with preemption, as we can easily get scheduled away from the CPU for a longer time than our timeout, in which case we would hit a spurious timeout and wrongly skip the PRE update. Instead of disabling preemption across the wait loop, potentially impacting the overall system latency, use a wait loop with a fixed max number of iterations, so time spent away from the CPU is not accounted against the timeout budget.

imx-drm doesn't mandate a modeset when the framebuffer modifier changes, but currently the tile prefetch and resolve (TPR) configuration of the PRE is only set up on the initial modeset. As the TPR configuration is double buffered, same as all the other PRE states, we can support dynamic reconfiguration of the buffer layout from one frame to another. As switching between (super-)tiled and linear prefetch needs to touch the CTRL register make sure to do the reconfiguration inside the safe window.

2024-06-26riscv: stacktrace: convert arch_stack_walk() to noinstrAndy Chiu
arch_stack_walk() is called intensively in function_graph when the kernel is compiled with CONFIG_TRACE_IRQFLAGS. As a result, the kernel logs a lot of arch_stack_walk and its sub-functions into the ftrace buffer. However, these functions should not appear on the trace log because they are part of the ftrace itself. This patch references what arm64 does for the smae function. So it further prevent the re-enter kprobe issue, which is also possible on riscv.

Avoid the link time warning by making the common driver a proper module with MODULE_LICENCE()/MODULE_AUTHOR() tags, and remove the __weak function by slightly rearranging the code.

2024-06-26xfs: honor init_xattrs in xfs_init_new_inode for !ATTR fsDarrick J. Wong
xfs_init_new_inode ignores the init_xattrs parameter for filesystems that do not have ATTR enabled. As a result, the first init_xattrs file to be created by the kernel will not have an attr fork created to store acls. Storing that first acl will add ATTR to the superblock flags, so subsequent files will be created with attr forks. The overhead of this is so small that chances are that nobody has noticed this behavior. However, this is disastrous on a filesystem with parent pointers because it requires that a new linkable file /must/ have a pre-existing attr fork, and the parent pointers code uses init_xattrs to create that fork. The preproduction version of mkfs.xfs used to set this, but the V5 sb verifier only requires ATTR2, not ATTR. There is no guard for filesystems with (PARENT && !ATTR). It turns out that I misunderstood the two flags -- ATTR means that we at some point created an attr fork to store xattrs in a file; ATTR2 apparently means only that inodes have dynamic fork offsets or that the filesystem was mounted with the "attr2" option.

For a very very long time, inode inactivation has set the inode size to zero before unmapping the extents associated with the data fork. Unfortunately, commit 3c6f46eacd876 changed the inode verifier to prohibit zero-length symlinks and directories. If an inode happens to get logged in this state and the system crashes before freeing the inode, log recovery will also fail on the broken inode. Therefore, allow zero-size symlinks and directories as long as the link count is zero; nobody will be able to open these files by handle so there isn't any risk of data exposure.

Looking at the trace data, we're trying to append a single fsblock to the "fred" file. Trying to create a speculative post-eof reservation fails because there's not enough space. We then set @prealloc_blocks to zero and try again, but the cowextsz alignment code triggers, which expands our request for a 1-fsblock reservation into a 39-block reservation. There's not enough space for that, so the whole write fails with ENOSPC even though there's sufficient space in the filesystem to allocate the single block that we need to land the write. There are two things wrong here -- first, we shouldn't be attempting speculative preallocations beyond what was requested when we're low on space. Second, if we've already computed a posteof preallocation, we shouldn't bother trying to align that to the cowextsize hint. Fix both of these problems by adding a flag that only enables the expansion of the delalloc reservation to the cowextsize if we're doing a non-extending write, and only if we're not doing an ENOSPC retry.

2024-06-26xfs: fix freeing speculative preallocations for preallocated filesChristoph Hellwig
xfs_can_free_eofblocks returns false for files that have persistent preallocations unless the force flag is passed and there are delayed blocks. This means it won't free delalloc reservations for files with persistent preallocations unless the force flag is set, and it will also free the persistent preallocations if the force flag is set and the file happens to have delayed allocations. Both of these are bad, so do away with the force flag and always free only post-EOF delayed allocations for files with the XFS_DIFLAG_PREALLOC or APPEND flags set.

2024-06-25tcp: fix tcp_rcv_fastopen_synack() to enter TCP_CA_Loss for failed TFONeal Cardwell
Testing determined that the recent commit 9e046bb111f1 ("tcp: clear tp->retrans_stamp in tcp_rcv_fastopen_synack()") has a race, and does not always ensure retrans_stamp is 0 after a TFO payload retransmit. If transmit completion for the SYN+data skb happens after the client TCP stack receives the SYNACK (which sometimes happens), then retrans_stamp can erroneously remain non-zero for the lifetime of the connection, causing a premature ETIMEDOUT later. Testing and tracing showed that the buggy scenario is the following somewhat tricky sequence: + Client attempts a TFO handshake. tcp_send_syn_data() sends SYN + TFO cookie + data in a single packet in the syn_data skb. It hands the syn_data skb to tcp_transmit_skb(), which makes a clone. Crucially, it then reuses the same original (non-clone) syn_data skb, transforming it by advancing the seq by one byte and removing the FIN bit, and enques the resulting payload-only skb in the sk->tcp_rtx_queue. + Client sets retrans_stamp to the start time of the three-way handshake. + Cookie mismatches or server has TFO disabled, and server only ACKs SYN. + tcp_ack() sees SYN is acked, tcp_clean_rtx_queue() clears retrans_stamp. + Since the client SYN was acked but not the payload, the TFO failure code path in tcp_rcv_fastopen_synack() tries to retransmit the payload skb. However, in some cases the transmit completion for the clone of the syn_data (which had SYN + TFO cookie + data) hasn't happened. In those cases, skb_still_in_host_queue() returns true for the retransmitted TFO payload, because the clone of the syn_data skb has not had its tx completetion. + Because skb_still_in_host_queue() finds skb_fclone_busy() is true, it sets the TSQ_THROTTLED bit and the retransmit does not happen in the tcp_rcv_fastopen_synack() call chain. + The tcp_rcv_fastopen_synack() code next implicitly assumes the retransmit process is finished, and sets retrans_stamp to 0 to clear it, but this is later overwritten (see below). + Later, upon tx completion, tcp_tsq_write() calls tcp_xmit_retransmit_queue(), which puts the retransmit in flight and sets retrans_stamp to a non-zero value. + The client receives an ACK for the retransmitted TFO payload data. + Since we're in CA_Open and there are no dupacks/SACKs/DSACKs/ECN to make tcp_ack_is_dubious() true and make us call tcp_fastretrans_alert() and reach a code path that clears retrans_stamp, retrans_stamp stays nonzero. + Later, if there is a TLP, RTO, RTO sequence, then the connection will suffer an early ETIMEDOUT due to the erroneously ancient retrans_stamp. The fix: this commit refactors the code to have tcp_rcv_fastopen_synack() retransmit by reusing the relevant parts of tcp_simple_retransmit() that enter CA_Loss (without changing cwnd) and call tcp_xmit_retransmit_queue(). We have tcp_simple_retransmit() and tcp_rcv_fastopen_synack() share code in this way because in both cases we get a packet indicating non-congestion loss (MTU reduction or TFO failure) and thus in both cases we want to retransmit as many packets as cwnd allows, without reducing cwnd. And given that retransmits will set retrans_stamp to a non-zero value (and may do so in a later calling context due to TSQ), we also want to enter CA_Loss so that we track when all retransmitted packets are ACked and clear retrans_stamp when that happens (to ensure later recurring RTOs are using the correct retrans_stamp and don't declare ETIMEDOUT prematurely).
