git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs Pull finegrained timestamp reverts from Christian Brauner: "Earlier this week we sent a few minor fixes for the multi-grained timestamp work in [1]. While we were polishing those up after Linus realized that there might be a nicer way to fix them we received a regression report in [2] that fine grained timestamps break gnulib tests and thus possibly other tools. The kernel will elide fine-grain timestamp updates when no one is actively querying for them to avoid performance impacts. So a sequence like write(f1) stat(f2) write(f2) stat(f2) write(f1) stat(f1) may result in timestamp f1 to be older than the final f2 timestamp even though f1 was last written too but the second write didn't update the timestamp. Such plotholes can lead to subtle bugs when programs compare timestamps. For example, the nap() function in [2] will estimate that it needs to wait one ns on a fine-grain timestamp enabled filesytem between subsequent calls to observe a timestamp change. But in general we don't update timestamps with more than one jiffie if we think that no one is actively querying for fine-grain timestamps to avoid performance impacts. While discussing various fixes the decision was to go back to the drawing board and ultimately to explore a solution that involves only exposing such fine-grained timestamps to nfs internally and never to userspace. As there are multiple solutions discussed the honest thing to do here is not to fix this up or disable it but to cleanly revert. The general infrastructure will probably come back but there is no reason to keep this code in mainline. The general changes to timestamp handling are valid and a good cleanup that will stay.

2023-09-21vsock/virtio: MSG_ZEROCOPY flag supportArseniy Krasnov
This adds handling of MSG_ZEROCOPY flag on transmission path: 1) If this flag is set and zerocopy transmission is possible (enabled in socket options and transport allows zerocopy), then non-linear skb will be created and filled with the pages of user's buffer. Pages of user's buffer are locked in memory by 'get_user_pages()'. 2) Replaces way of skb owning: instead of 'skb_set_owner_sk_safe()' it calls 'skb_set_owner_w()'. Reason of this change is that '__zerocopy_sg_from_iter()' increments 'sk_wmem_alloc' of socket, so to decrease this field correctly, proper skb destructor is needed: 'sock_wfree()'. This destructor is set by 'skb_set_owner_w()'. 3) Adds new callback to 'struct virtio_transport': 'can_msgzerocopy'. If this callback is set, then transport needs extra check to be able to send provided number of buffers in zerocopy mode. Currently, the only transport that needs this callback set is virtio, because this transport adds new buffers to the virtio queue and we need to check, that number of these buffers is less than size of the queue (it is required by virtio spec). vhost and loopback transports don't need this check.

2023-09-21vsock/virtio/vhost: read data from non-linear skbArseniy Krasnov
This is preparation patch for MSG_ZEROCOPY support. It adds handling of non-linear skbs by replacing direct calls of 'memcpy_to_msg()' with 'skb_copy_datagram_iter()'. Main advantage of the second one is that it can handle paged part of the skb by using 'kmap()' on each page, but if there are no pages in the skb, it behaves like simple copying to iov iterator. This patch also adds new field to the control block of skb - this value shows current offset in the skb to read next portion of data (it doesn't matter linear it or not). Idea behind this field is that 'skb_copy_datagram_iter()' handles both types of skb internally - it just needs an offset from which to copy data from the given skb. This offset is incremented on each read from skb. This approach allows to simplify handling of both linear and non-linear skbs, because for linear skb we need to call 'skb_pull()' after reading data from it, while in non-linear case we need to update 'data_len'.

2023-09-21igc: Expose tx-usecs coalesce setting to userMuhammad Husaini Zulkifli
When users attempt to obtain the coalesce setting using the ethtool command, current code always returns 0 for tx-usecs. This is because I225/6 always uses a queue pair setting, hence tx_coalesce_usecs does not return a value during the igc_ethtool_get_coalesce() callback process. The pair queue condition checking in igc_ethtool_get_coalesce() is removed by this patch so that the user gets information of the value of tx-usecs. Even if i225/6 is using queue pair setting, there is no harm in notifying the user of the tx-usecs. The implementation of the current code may have previously been a copy of the legacy code i210. Since I225 has the queue pair setting enabled, tx-usecs will always adhere to the user-set rx-usecs value. An error message will appear when the user attempts to set the tx-usecs value for the input parameters because, by default, they should only set the rx-usecs value. This patch also adds the helper function to get the previous rx coalesce value similar to tx coalesce. How to test: User can get the coalesce value using ethtool command. Example command: Get: ethtool -c <interface> Previous output: rx-usecs: 3 rx-frames: n/a rx-usecs-irq: n/a rx-frames-irq: n/a tx-usecs: 0 tx-frames: n/a tx-usecs-irq: n/a tx-frames-irq: n/a New output: rx-usecs: 3 rx-frames: n/a rx-usecs-irq: n/a rx-frames-irq: n/a tx-usecs: 3 tx-frames: n/a tx-usecs-irq: n/a tx-frames-irq: n/a Fixes: 8c5ad0dae93c ("igc: Add ethtool support") Signed-off-by: Muhammad Husaini Zulkifli <muhammad.husaini.zulkifli@intel.com> Tested-by: Naama Meir <naamax.meir@linux.intel.com> Reviewed-by: Simon Horman <horms@kernel.org> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com> Link: https://lore.kernel.org/r/20230919170331.1581031-1-anthony.l.nguyen@intel.com Signed-off-by: Paolo Abeni <pabeni@redhat.com>

2023-09-20net/handshake: Fix memory leak in __sock_create() and sock_alloc_file()Jinjie Ruan
When making CONFIG_DEBUG_KMEMLEAK=y and CONFIG_DEBUG_KMEMLEAK_AUTO_SCAN=y, modprobe handshake-test and then rmmmod handshake-test, the below memory leak is detected. The struct socket_alloc which is allocated by alloc_inode_sb() in __sock_create() is not freed. And the struct dentry which is allocated by __d_alloc() in sock_alloc_file() is not freed. Since fput() will call file->f_op->release() which is sock_close() here and it will call __sock_release(). and fput() will call dput(dentry) to free the struct dentry. So replace sock_release() with fput() to fix the below memory leak. After applying this patch, the following memory leak is never detected. unreferenced object 0xffff888109165840 (size 768): comm "kunit_try_catch", pid 1852, jiffies 4294685807 (age 976.262s) hex dump (first 32 bytes): 01 00 00 00 01 00 5a 5a 20 00 00 00 00 00 00 00 ......ZZ ....... 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ backtrace: [<ffffffff8397993f>] sock_alloc_inode+0x1f/0x1b0 [<ffffffff81a2cb5b>] alloc_inode+0x5b/0x1a0 [<ffffffff81a32bed>] new_inode_pseudo+0xd/0x70 [<ffffffff8397889c>] sock_alloc+0x3c/0x260 [<ffffffff83979b46>] __sock_create+0x66/0x3d0 [<ffffffffa0209ba2>] 0xffffffffa0209ba2 [<ffffffff829cf03a>] kunit_generic_run_threadfn_adapter+0x4a/0x90 [<ffffffff81236fc6>] kthread+0x2b6/0x380 [<ffffffff81096afd>] ret_from_fork+0x2d/0x70 [<ffffffff81003511>] ret_from_fork_asm+0x11/0x20 unreferenced object 0xffff88810f472008 (size 192): comm "kunit_try_catch", pid 1852, jiffies 4294685808 (age 976.261s) hex dump (first 32 bytes): 00 00 50 40 02 00 00 00 00 00 00 00 00 00 00 00 ..P@............ 00 00 00 00 00 00 00 00 08 20 47 0f 81 88 ff ff .........

2023-09-20ionic: expand the descriptor bufs arrayShannon Nelson
When processing a TSO we may have frags spread across several descriptors, and the total count of frags in one skb may exceed our per descriptor IONIC_MAX_FRAGS: this is fine as long as each descriptor has fewer frags than the limit. Since the skb could have as many as MAX_SKB_FRAGS, and the first descriptor is where we track and map the frag buffers, we need to be sure we can map buffers for all of the frags plus the TSO header in the first descriptor's buffer array.

2023-09-20ionic: add a check for max SGs and SKB fragsShannon Nelson

2023-09-20ionic: count SGs in packet to minimize linearizeShannon Nelson
There are some cases where an skb carries more frags than the number of SGs that ionic can support per descriptor - this forces the driver to linearize the skb. However, if this is a TSO packet that is going to become multiple descriptors (one per MTU-sized packet) and spread the frags across them, this time-consuming linearization is likely not necessary. We scan the frag list and count up the number of SGs that would be created for each descriptor that would be generated, and only linearize if we hit the SG limit on a descriptor. In most cases, we won't even get to the frag list scan, so this doesn't affect typical traffic. Signed-off-by: Shannon Nelson <shannon.nelson@amd.com> Signed-off-by: David S.

Sergey prepends ICE_ to PTP timer commands to clearly convey namespace of commands. Karol adds retrying to acquire hardware semaphore for cross-timestamping and avoids writing to timestamp registers on E822 devices. He also renames some defines to be more clear and align with the data sheet. Additionally, a range check is moved in order to reduce duplicated code. Jake adds cross-timestamping support for E823 devices as well as adds checks against netlist to aid in determining support for GNSS. He also corrects improper pin assignment for certain E810-T devices and refactors/cleanups PTP related code such as adding PHY model to ease checks for different needed implementations, removing unneeded EXTTS flag, and adding macro to check for source timer owner. ==================== Signed-off-by: David S.

Uwe Kleine-König says: ==================== net: mdio: Convert to platform remove callback returning void this series convert all platform drivers below drivers/net/mdio to use remove_new. The motivation is to get rid of an integer return code that is (mostly) ignored by the platform driver core and error prone on the driver side. See commit 5c5a7680e67b ("platform: Provide a remove callback that returns no value") for an extended explanation and the eventual goal. There are no interdependencies between the patches. As there are still quite a few drivers to convert, I'm happy about every patch that makes it in. So even if there is a merge conflict with one patch until you apply, please apply the remainder of this series anyhow. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2023-09-20net: mdio: xgene: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Eventually after all drivers are converted, .remove_new() is renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: David S.
