TCP allocates 'fast clones' skbs for packets in tx queues. Currently, __alloc_skb() initializes the companion fclone field to SKB_FCLONE_CLONE, and leaves other fields untouched. It makes sense to defer this init much later in skb_clone(), because all fclone fields are copied and hot in cpu caches at that time. This removes one cache line miss in __alloc_skb(), cost seen on an host with 256 cpus all competing on memory accesses. Signed-off-by:

Current implementation is such that driver first resets the existing PFC config before applying new pfc configuration. This creates a problem like once PF or VFs requests PFC config previous pfc config by other PFVfs is getting reset. This patch fixes the problem by removing unnecessary resetting of PFC config. Also configure Pause quanta value to smaller as current value is too high. Signed-off-by:

When building with Clang we encounter the following warnings: | net/l2tp/l2tp_debugfs.c:187:40: error: format specifies type 'unsigned | short' but the argument has type 'u32' (aka 'unsigned int') | [-Werror,-Wformat] seq_printf(m, " nr %hu, ns %hu\n", session->nr, | session->ns); - | net/l2tp/l2tp_debugfs.c:196:32: error: format specifies type 'unsigned | short' but the argument has type 'int' [-Werror,-Wformat] | session->l2specific_type, l2tp_get_l2specific_len(session)); - | net/l2tp/l2tp_debugfs.c:219:6: error: format specifies type 'unsigned | short' but the argument has type 'u32' (aka 'unsigned int') | [-Werror,-Wformat] session->nr, session->ns, Both session->nr and ->nc are of type `u32`. The currently used format specifier is `%hu` which describes a `u16`. My proposed fix is to listen to Clang and use the correct format specifier `%u`. For the warning at line 196, l2tp_get_l2specific_len() returns an int and should therefore be using the `%d` format specifier. Link: https://github.com/ClangBuiltLinux/linux/issues/378Signed-off-by:

Conor Dooley says: ==================== PolarFire SoC macb reset support The Cadence MACBs on PolarFire SoC (MPFS) have reset capability and are compatible with the zynqmp's init function. I have removed the zynqmp specific comments from that function & renamed it to reflect what it does, since it is no longer zynqmp only. MPFS's MACB had previously used the generic binding, so I also added the required specific binding. For v2, I noticed some low hanging cleanup fruit so there are extra patches added for that: moving the init function out of the config structs, aligning the alignment of the zynqmp & default config structs with the other dozen or so structs & simplifing the error paths to use dev_err_probe(). Feel free to apply as many or as few of those as you like. ==================== Link: https://lore.kernel.org/r/20220706095129.828253-1-conor.dooley@microchip.comSigned-off-by:

To date, the Microchip PolarFire SoC (MPFS) has been using the cdns,macb compatible, however the generic device does not have reset support. Add a new compatible & .data for MPFS to hook into the reset functionality added for zynqmp support (and make the zynqmp init function generic in the process). Reviewed-by:

When building with clang we encounter this warning: | net/l2tp/l2tp_ppp.c:1557:6: error: format specifies type 'unsigned | short' but the argument has type 'u32' (aka 'unsigned int') | [-Werror,-Wformat] session->nr, session->ns, Both session->nr and session->ns are of type u32. The format specifier previously used is `%hu` which would truncate our unsigned integer from 32 to 16 bits. This doesn't seem like intended behavior, if it is then perhaps we need to consider suppressing the warning with pragma clauses. This patch should get us closer to the goal of enabling the -Wformat flag for Clang builds. Link: https://github.com/ClangBuiltLinux/linux/issues/378Signed-off-by:

Currently NIC packet receiving performance based on page pool deteriorates occasionally. To analysis the causes of this problem page allocation stats are collected. Here are the stats when NIC rx performance deteriorates: bandwidth(Gbits/s) 16.8 6.91 rx_pp_alloc_fast 13794308 21141869 rx_pp_alloc_slow 108625 166481 rx_pp_alloc_slow_h 0 0 rx_pp_alloc_empty 8192 8192 rx_pp_alloc_refill 0 0 rx_pp_alloc_waive 100433 158289 rx_pp_recycle_cached 0 0 rx_pp_recycle_cache_full 0 0 rx_pp_recycle_ring 362400 420281 rx_pp_recycle_ring_full 6064893 9709724 rx_pp_recycle_released_ref 0 0 The rx_pp_alloc_waive count indicates that a large number of pages' numa node are inconsistent with the NIC device numa node. Therefore these pages can't be reused by the page pool. As a result, many new pages would be allocated by __page_pool_alloc_pages_slow which is time consuming. This causes the NIC rx performance fluctuations. The main reason of huge numa mismatch pages in page pool is that page pool uses alloc_pages_bulk_array to allocate original pages. This function is not suitable for page allocation in NUMA scenario. So this patch uses alloc_pages_bulk_array_node which has a NUMA id input parameter to ensure the NUMA consistent between NIC device and allocated pages. Repeated NIC rx performance tests are performed 40 times. NIC rx bandwidth is higher and more stable compared to the datas above. Here are three test stats, the rx_pp_alloc_waive count is zero and rx_pp_alloc_slow which indicates pages allocated from slow patch is relatively low. bandwidth(Gbits/s) 93 93.9 93.8 rx_pp_alloc_fast 60066264 61266386 60938254 rx_pp_alloc_slow 16512 16517 16539 rx_pp_alloc_slow_ho 0 0 0 rx_pp_alloc_empty 16512 16517 16539 rx_pp_alloc_refill 473841 481910 481585 rx_pp_alloc_waive 0 0 0 rx_pp_recycle_cached 0 0 0 rx_pp_recycle_cache_full 0 0 0 rx_pp_recycle_ring 29754145 30358243 30194023 rx_pp_recycle_ring_full 0 0 0 rx_pp_recycle_released_ref 0 0 0 Signed-off-by:

These are indeed "should not happen" situations, but it turns out recent changes made the 'task_is_stopped_or_trace()' case trigger (fix for that exists, is pending more testing), and the BUG_ON() makes it unnecessarily hard to actually debug for no good reason. It's been that way for a long time, but let's make it clear: BUG_ON() is not good for debugging, and should never be used in situations where you could just say "this shouldn't happen, but we can continue". Use WARN_ON_ONCE() instead to make sure it gets logged, and then just continue running. Instead of making the system basically unusuable because you crashed the machine while potentially holding some very core locks (eg this function is commonly called while holding 'tasklist_lock' for writing).

Commit 6dd4142f ("Merge branch 'af_unix-per-netns-socket-hash'") and commit 51bae889 ("af_unix: Put pathname sockets in the global hash table.") changed a hash table layout. Before: unix_socket_table [0 - 255] : abstract & pathname sockets [256 - 511] : unnamed sockets After: per-netns table [0 - 255] : abstract & pathname sockets [256 - 511] : unnamed sockets bsd_socket_table [0 - 255] : pathname sockets (sk_bind_node) Now, while looking up sockets, we traverse the global table for the pathname sockets and the first half of each per-netns hash table for abstract sockets, where pathname sockets are also linked. Thus, the more pathname sockets we have, the longer we take to look up abstract sockets. This characteristic has been there before the layout change, but we can improve it now. This patch changes the per-netns hash table's layout so that sockets not requiring lookup reside in the first half and do not impact the lookup of abstract sockets. per-netns table [0 - 255] : pathname & unnamed sockets [256 - 511] : abstract sockets bsd_socket_table [0 - 255] : pathname sockets (sk_bind_node) We have run a test that bind()s 100,000 abstract/pathname sockets for each, bind()s an abstract socket 100,000 times and measures the time on __unix_find_socket_byname(). The result shows that the patch makes each lookup faster.

Jason A. Donenfeld says: ==================== wireguard patches for 5.19-rc6 1) A few small fixups to the selftests, per usual. Of particular note is a fix for a test flake that occurred on especially fast systems that boot in less than a second. 2) An addition during this cycle of some s390 crypto interacted with the way wireguard selects dependencies, resulting in linker errors reported by the kernel test robot. So Vladis sent in a patch for that, which also required a small preparatory fix moving some Kconfig symbols around. ==================== Link: https://lore.kernel.org/r/20220707003157.526645-1-Jason@zx2c4.comSigned-off-by:

Various accelerated software implementation Kconfig values for S390 were mistakenly placed into drivers/crypto/Kconfig, even though they're mainly just SIMD code and live in arch/s390/crypto/ like usual. This gives them the very unusual dependency on CRYPTO_HW, which leads to problems elsewhere. This patch fixes the issue by moving the Kconfig values for non-hardware drivers into the usual place in crypto/Kconfig. Acked-by:

Jason A. Donenfeld authored
Not all platforms have an RTC, and rather than trying to force one into each, it's much easier to just set a fixed time. This is necessary because WireGuard's latest handshakes parameter is returned in wallclock time, and if the system time isn't set, and the system is really fast, then this returns 0, which trips the test. Turning this on requires setting CONFIG_COMPAT_32BIT_TIME=y, as musl doesn't support settimeofday without it. Signed-off-by:

There are UAF bugs caused by rose_t0timer_expiry(). The root cause is that del_timer() could not stop the timer handler that is running and there is no synchronization.

This patch changes rose_stop_ftimer() and rose_stop_t0timer() in rose_remove_neigh() to del_timer_sync() in order that the timer handler could be finished before the resources such as rose_neigh and so on are deallocated.
