2023-11-27net: phy: add possible interfacesRussell King (Oracle)
Add a possible_interfaces member to struct phy_device to indicate which interfaces a clause 45 PHY may switch between depending on the media. This must be populated by the PHY driver by the time the .config_init() method completes according to the PHYs host-side configuration. For example, the Marvell 88x3310 PHY can switch between 10GBASE-R, 5GBASE-R, 2500BASE-X, and SGMII on the host side depending on the media side speed, so all these interface modes are set in the possible_interfaces member. This allows phylib users (such as phylink) to know in advance which interface modes to expect, which allows them to appropriately restrict the advertised link modes according to the capabilities of other parts of the link.

2023-11-26mm/page_pool: catch page_pool memory leaksJesper Dangaard Brouer
Pages belonging to a page_pool (PP) instance must be freed through the PP APIs in-order to correctly release any DMA mappings and release refcnt on the DMA device when freeing PP instance. When PP release a page (page_pool_release_page) the page->pp_magic value is cleared. This patch detect a leaked PP page in free_page_is_bad() via unexpected state of page->pp_magic value being PP_SIGNATURE. We choose to report and treat it as a bad page. It would be possible to release the page via returning it to the PP instance as the page->pp pointer is likely still valid. Notice this code is only activated when either compiled with CONFIG_DEBUG_VM or boot cmdline debug_pagealloc=on, and CONFIG_PAGE_POOL. Reduced example output of leak with PP_SIGNATURE = dead000000000040: BUG: Bad page state in process swapper/4 pfn:141fa6 page:000000006dbf8062 refcount:0 mapcount:0 mapping:0000000000000000 index:0x141fa6000 pfn:0x141fa6 flags: 0x2fffff80000000(node=0|zone=2|lastcpupid=0x1fffff) page_type: 0xffffffff() raw: 002fffff80000000 dead000000000040 ffff88814888a000 0000000000000000 raw: 0000000141fa6000 0000000000000001 00000000ffffffff 0000000000000000 page dumped because: page_pool leak [...] Call Trace: <IRQ> dump_stack_lvl+0x32/0x50 bad_page+0x70/0xf0 free_unref_page_prepare+0x263/0x430 free_unref_page+0x34/0x130 mlx5e_free_rx_mpwqe+0x190/0x1c0 [mlx5_core] mlx5e_post_rx_mpwqes+0x1ac/0x280 [mlx5_core] mlx5e_napi_poll+0x12b/0x710 [mlx5_core] ? skb_free_head+0x4f/0x90 __napi_poll+0x2b/0x1c0 net_rx_action+0x27b/0x360 The advantage is the Call Trace directly points to the function leaking the PP page, which in this case is an on purpose bug introduced into the mlx5 driver to test this code change. Currently PP will periodically in page_pool_release_retry() printk warning "stalled pool shutdown" which cannot be directly corrolated to leaking and might as well be a false positive due to SKBs being stuck on a socket for an extended period.

RollBall SFP modules allow the access to PHY registers only after a certain time has passed. Until then, the registers read 0xffff. Currently we have quirks for modules where we need to wait either 25 seconds or 4 seconds, but recently I got hands on another module where the wait is even shorter.

The commit dcd2cf5f2fc0 ("net/smc: add autocorking support") adds an atomic variable tx_pushing in smc_connection to make sure only one can send to let it cork more and save CDC slot. since smc_tx_pending can be called in the soft IRQ without checking sock_owned_by_user() at that time, which would cause a race condition because bh_lock_sock() did not honor sock_lock() After commit 6b88af839d20 ("net/smc: don't send in the BH context if sock_owned_by_user"), the transmission is deferred to when sock_lock() is held by the user. Therefore, we no longer need tx_pending to hold message. So remove atomic variable tx_pushing and its operation, and smc_tx_sndbuf_nonempty becomes a wrapper of __smc_tx_sndbuf_nonempty, so rename __smc_tx_sndbuf_nonempty back to smc_tx_sndbuf_nonempty Suggested-by: Alexandra Winter <wintera@linux.ibm.com> Co-developed-by: Dust Li <dust.li@linux.alibaba.com> Signed-off-by: Dust Li <dust.li@linux.alibaba.com> Signed-off-by: Li RongQing <lirongqing@baidu.com> Reviewed-by: Alexandra Winter <wintera@linux.ibm.com> diff v4: remove atomic variable tx_pushing diff v3: improvements in the commit body and comments diff v2: fix a typo in commit body and add net-next subject-prefix net/smc/smc.h | 1 - net/smc/smc_tx.c | 30 +----------------------------- 2 files changed, 1 insertion(+), 30 deletions(-) Signed-off-by: David S.

Max receive packet length can vary across SoCs, so this needs to be queried from respective firmware and filled by driver. A control net get mtu api should be implemented to do the same. Signed-off-by: Shinas Rasheed <srasheed@marvell.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2023-11-24net: phy: correctly check soft_reset ret ONLY if defined for PHYChristian Marangi
Introduced by commit 6e2d85ec0559 ("net: phy: Stop with excessive soft reset"). soft_reset call for phy_init_hw had multiple revision across the years and the implementation goes back to 2014. Originally was a simple call to write the generic PHY reset BIT, it was then moved to a dedicated function. It was then added the option for PHY driver to define their own special way to reset the PHY. Till this change, checking for ret was correct as it was always filled by either the generic reset or the custom implementation. This changed tho with commit 6e2d85ec0559 ("net: phy: Stop with excessive soft reset"), as the generic reset call to PHY was dropped but the ret check was never made entirely optional and dependent whether soft_reset was defined for the PHY driver or not. Luckly nothing was ever added before the soft_reset call so the ret check (in the case where a PHY didn't had soft_reset defined) although wrong, never caused problems as ret was init 0 at the start of phy_init_hw. To prevent any kind of problem and to make the function cleaner and more robust, correctly move the ret check if the soft_reset section making it optional and needed only with the function defined.

2023-11-24Documentation: Document each netlink familyBreno Leitao
This is a simple script that parses the Netlink YAML spec files (Documentation/netlink/specs/), and generates RST files to be rendered in the Network -> Netlink Specification documentation page. Create a python script that is invoked during 'make htmldocs', reads the YAML specs input file and generate the correspondent RST file. Create a new Documentation/networking/netlink_spec index page, and reference each Netlink RST file that was processed above in this main index.rst file. In case of any exception during the parsing, dump the error and skip the file. Do not regenerate the RST files if the input files (YAML) were not changed in-between invocations. Suggested-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: Breno Leitao <leitao@debian.org> ---- Changelog: V3: * Do not regenerate the RST files if the input files were not changed. In order to do it, a few things changed: - Rely on Makefile more to find what changed, and trigger individual file processing - The script parses file by file now (instead of batches) - Create a new option to generate the index file V2: * Moved the logic from a sphinx extension to a external script * Adjust some formatting as suggested by Donald Hunter and Jakub * Auto generating all the rsts instead of having stubs * Handling error gracefully Reviewed-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S.

2023-11-23tools: ynl: fix duplicate op name in devlinkJakub Kicinski
We don't support CRUD-inspired message types in YNL too well. One aspect that currently trips us up is the fact that single message ID can be used in multiple commands (as the response). This leads to duplicate entries in the id-to-string tables: devlink-user.c:19:34: warning: initialized field overwritten [-Woverride-init] 19 | [DEVLINK_CMD_PORT_NEW] = "port-new", | ^~~~~~~~~~ devlink-user.c:19:34: note: (near initialization for ‘devlink_op_strmap[7]’) Fixes tag points at where the code was generated, the "real" problem is that the code generator does not support CRUD.
