When getting a chunk map, at btrfs_get_chunk_map(), we do some sanity checks to verify that we found an extent map and that it includes the requested logical address. These are never expected to fail, so mark them as unlikely to make it more clear as well as to allow a compiler to generate more efficient code. Reviewed-by:

Looks like the struct member was added in 2007 in 2.6.29 in commit 87ee04eb ("Btrfs: Add simple stripe size parameter") but hasn't been used at all since. So let's remove it. This was found by tool https://github.com/jirislaby/clang-struct, then build tested after removing the struct member. Reviewed-by:

As a cleanup and preparation for future folio migration, this patch would replace all page->private to folio version. This includes: - PagePrivate() -> folio_test_private() - page->private -> folio_get_private() - attach_page_private() -> folio_attach_private() - detach_page_private() -> folio_detach_private() Since we're here, also remove the forced cast on page->private, since it's (void *) already, we don't really need to do the cast. For now even if we missed some call sites, it won't cause any problem yet, as we're only using order 0 folio (single page), thus all those folio/page flags should be synced. But for the future conversion to utilize higher order folio, the page <-> folio flag sync is no longer guaranteed, thus we have to migrate to utilize folio flags. Reviewed-by:

The pages are now allocated and freed centrally, so we can extend the logic to manage the lifetime. The main idea is to keep a few recently used pages and hand them to all writers. Ideally we won't have to go to allocator at all (a slight performance gain) and also raise chance that we'll have the pages available (slightly increased reliability). In order to avoid gathering too many pages, the shrinker is attached to the cache so we can free them on when MM demands that. The first implementation will drain the whole cache. Further this can be refined to keep some minimal number of pages for emergency purposes. The ultimate goal to avoid memory allocation failures on the write out path from the compression. The pool threshold is set to cover full BTRFS_MAX_COMPRESSED / PAGE_SIZE for minimal thread pool, which is 8 (btrfs_init_fs_info()). This is 128K / 4K * 8 = 256 pages at maximum, which is 1MiB. This is for all filesystems currently mounted, with heavy use of compression IO the allocator is still needed. The cache helps for short burst IO. Reviewed-by:

David Sterba authored
This is a preparation for managing compression pages in a cache-like manner, instead of asking the allocator each time. The common allocation and free wrappers are introduced and are functionally equivalent to the current code. The freeing helpers need to be carefully placed where the last reference is dropped. This is either after directly allocating (error handling) or when there are no other users of the pages (after copying the contents). It's safe to not use the helper and use put_page() that will handle the reference count. Not using the helper means there's lower number of pages that could be reused without passing them back to allocator. Reviewed-by:

[PROBLEM] The function __btrfs_update_delayed_inode() is doing something not meeting the code standard of today: path->slots[0]++ if (path->slots[0] >= btrfs_header_nritems(leaf)) goto search; again: if (!is_the_target_inode_ref()) goto out; ret = btrfs_delete_item(); /* Some cleanup. */ return ret; search: ret = search_for_the_last_inode_ref(); goto again; With the tag named "again", it's pretty common to think it's a loop, but the truth is, we only need to do the search once, to locate the last (also the first, since there should only be one INODE_REF or INODE_EXTREF now) ref of the inode. [FIX] Instead of the weird jumps, just do them in a stream-lined fashion. This removes those weird labels, and add extra comments on why we can do the different searches. Reviewed-by:

The logic in btrfs_block_can_be_shared() is hard to follow as we have a lot of conditions in a single if statement including a subexpression with a logical or and two nested if statements inside the main if statement. Make this easier to read by using separate if statements that return immediately when we find a condition that determines if a block can be or can not be shared. Signed-off-by:

Filipe Manana authored
Currently btrfs_block_can_be_shared() returns an int that is used as a boolean. Since it all it needs is to return true or false, and it can't return errors for example, change the return type from int to bool to make it a bit more readable and obvious. Reviewed-by:

Because atalk_ioctl() accesses sk->sk_receive_queue without holding a sk->sk_receive_queue.lock, it can cause a race with atalk_recvmsg(). A use-after-free for skb occurs with the following flow. ``` atalk_ioctl() -> skb_peek() atalk_recvmsg() -> skb_recv_datagram() -> skb_free_datagram() ``` Add sk->sk_receive_queue.lock to atalk_ioctl() to fix this issue.

Starting with commit 4e51bf44 ("net: bridge: move the switchdev object replay helpers to "push" mode") the switchdev_bridge_port_offload() helper was extended with the intention to provide switchdev drivers easy access to object addition and deletion replays. This works by calling the replay helpers with non-NULL notifier blocks. In the same commit, the dpaa2-switch driver was updated so that it passes valid notifier blocks to the helper. At that moment, no regression was identified through testing. In the meantime, the blamed commit changed the behavior in terms of which ports get hit by the replay. Before this commit, only the initial port which identified itself as offloaded through switchdev_bridge_port_offload() got a replay of all port objects and FDBs. After this, the newly joining port will trigger a replay of objects on all bridge ports and on the bridge itself. This behavior leads to errors in dpaa2_switch_port_vlans_add() when a VLAN gets installed on the same interface multiple times. The intended mechanism to address this is to pass a non-NULL ctx to the switchdev_bridge_port_offload() helper and then check it against the port's private structure. But since the driver does not have any use for the replayed port objects and FDBs until it gains support for LAG offload, it's better to fix the issue by reverting the dpaa2-switch driver to not ask for replay. The pointers will be added back when we are prepared to ignore replays on unrelated ports. Fixes: b28d580e ("net: bridge: switchdev: replay all VLAN groups") Signed-off-by:

Once again syzbot is able to crash the kernel in skb_segment() [1] GSO_BY_FRAGS is a forbidden value, but unfortunately the following computation in skb_segment() can reach it quite easily : mss = mss * partial_segs; 65535 = 3 * 5 * 17 * 257, so many initial values of mss can lead to a bad final result. Make sure to limit segmentation so that the new mss value is smaller than GSO_BY_FRAGS.

There are some wrong return values check in sign-file when call OpenSSL API. The ERR() check cond is wrong because of the program only check the return value is < 0 which ignored the return val is 0. For example: 1. CMS_final() return 1 for success or 0 for failure. 2. i2d_CMS_bio_stream() returns 1 for success or 0 for failure. 3. i2d_TYPEbio() return 1 for success and 0 for failure. 4. BIO_free() return 1 for success and 0 for failure.

Based on the tcp man page, if TCP_NODELAY is set, it disables Nagle's algorithm and packets are sent as soon as possible. However in the `tcp_push` function where autocorking is evaluated the `nonagle` value set by TCP_NODELAY is not considered which can trigger unexpected corking of packets and induce delays. For example, if two packets are generated as part of a server's reply, if the first one is not transmitted on the wire quickly enough, the second packet can trigger the autocorking in `tcp_push` and be delayed instead of sent as soon as possible. It will either wait for additional packets to be coalesced or an ACK from the client before transmitting the corked packet. This can interact badly if the receiver has tcp delayed acks enabled, introducing 40ms extra delay in completion times. It is not always possible to control who has delayed acks set, but it is possible to adjust when and how autocorking is triggered. Patch prevents autocorking if the TCP_NODELAY flag is set on the socket. Patch has been tested using an AWS c7g.2xlarge instance with Ubuntu 22.04 and Apache Tomcat 9.0.83 running the basic servlet below: import java.io.IOException; import java.io.OutputStreamWriter; import java.io.PrintWriter; import javax.servlet.ServletException; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; public class HelloWorldServlet extends HttpServlet { @Override protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { response.setContentType("text/html;charset=utf-8"); OutputStreamWriter osw = new OutputStreamWriter(response.getOutputStream(),"UTF-8"); String s = "a".repeat(3096); osw.write(s,0,s.length()); osw.flush(); } } Load was applied using wrk2 (https://github.com/kinvolk/wrk2) from an AWS c6i.8xlarge instance. With the current auto-corking behavior and TCP_NODELAY set an additional 40ms latency from P99.99+ values are observed. With the patch applied we see no occurrences of 40ms latencies. The patch has also been tested with iperf and uperf benchmarks and no regression was observed. # No patch with tcp_autocorking=1 and TCP_NODELAY set on all sockets ./wrk -t32 -c128 -d40s --latency -R10000 http://172.31.49.177:8080/hello/hello' ... 50.000% 0.91ms 75.000% 1.12ms 90.000% 1.46ms 99.000% 1.73ms 99.900% 1.96ms 99.990% 43.62ms <<< 40+ ms extra latency 99.999% 48.32ms 100.000% 49.34ms # With patch ./wrk -t32 -c128 -d40s --latency -R10000 http://172.31.49.177:8080/hello/hello' ... 50.000% 0.89ms 75.000% 1.13ms 90.000% 1.44ms 99.000% 1.67ms 99.900% 1.78ms 99.990% 2.27ms <<< no 40+ ms extra latency 99.999% 3.71ms 100.000% 4.57ms Fixes: f54b3111 ("tcp: auto corking") Signed-off-by:Salvatore Dipietro <dipiets@amazon.com> Reviewed-by:
