Data center server CPUs number keeps getting larger with time. Currently, our driver limits the number of channels to 128. Maximum channels number is enforced and bounded by hardcoded defines (en.h/MLX5E_MAX_NUM_CHANNELS) even though the device and machine (CPUs num) can allow more. Refactor current implementation in order to handle further channels. The maximum supported channels number will be increased in the followup patch. Introduce RQT size calculation/allocation scheme below: 1) Preserve current RQT size of 256 for channels number up to 128 (the old limit). 2) For greater channels number, RQT size is calculated by multiplying the channels number by 2 and rounding up the result to the nearest power of 2. If the calculated RQT size exceeds the maximum supported size by the NIC, fallback to this maximum RQT size (1 << log_max_rqt_size). Since RQT size is no more static, allocate and free the indirection table SW shadow dynamically. Signed-off-by:

Introduce code refactoring below: 1) Introduce single API for creating and destroying rss object, mlx5e_rss_create() and mlx5e_rss_destroy() respectively. 2) mlx5e_rss_create() constructs and initializes RSS object depends on a function new param enum mlx5e_rss_create_type. Callers (like rx_res.c) will no longer need to allocate RSS object via mlx5e_rss_alloc() and initialize it immediately via mlx5e_rss_init_no_tirs() or mlx5e_rss_init(), this will be done by a single call to mlx5e_rss_create(). Hence, mlx5e_rss_alloc() and mlx5e_rss_init_no_tirs() have been removed from rss.h file and became static functions. Signed-off-by:

Initialize indirect table array with memcpy rather than for loop. This change has made for two reasons: 1) To be consistent with the indirect table array init in mlx5e_rss_set_rxfh(). 2) In general, prefer to use memcpy for array initializing rather than for loop. Signed-off-by:

mlx5_intf_lock is used to sync between LAG changes and its slaves mlx5 core dev aux devices changes, which means every time mlx5 core dev add/remove aux devices, mlx5 is taking this global lock, even if LAG functionality isn't supported over the core dev. This cause a bottleneck when probing VFs/SFs in parallel. Hence, replace mlx5_intf_lock with HCA devcom component lock, or no lock if LAG functionality isn't supported. Signed-off-by:

active_work is a work that iterates over all possible SF devices which their SF port representors are located on different function, and in case SF is in active state, probes it. Currently, the active_work in active_wq is synced with mlx5_vhca_events_work via table_lock and this lock causing a bottleneck in performance. To remove table_lock, redesign active_wq logic so that it now pushes active_work per SF to mlx5_vhca_events_workqueues. Since the latter workqueues are ordered, active_work and mlx5_vhca_events_work with same index will be pushed into same workqueue, thus it completely eliminates the need for a lock. Signed-off-by:

At present, mlx5 driver have a general purpose event handler which not only handles vhca event but also many other events. This incurs a huge bottleneck because the event handler is implemented by single threaded workqueue and all events are forced to be handled in serial manner even though application tries to create multiple SFs simultaneously. Introduce a dedicated vhca event handler which manages SFs parallel creation. Signed-off-by:

strncpy() is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. This patch eliminates three uses of strncpy(): Firstly, `dest` is expected to be NUL-terminated which is evident by the manual setting of a NUL-byte at size - 1. For this use specifically, strscpy() is a viable replacement due to the fact that it guarantees NUL-termination on the destination buffer. The next two cases should simply be memcpy() as the size of the src string is always 3 and the destination string just wants the first 3 bytes changed. To be clear, there are no buffer overread bugs in the current code as the sizes and offsets are carefully managed such that buffers are NUL-terminated. However, with these changes, the code is now more robust and less ambiguous (and hopefully easier to read).

In very rare cases (I've seen two reports so far about different RTL8125 chip versions) it seems the MAC locks up when link goes down and requires a software reset to get revived. Realtek doesn't publish hw errata information, therefore the root cause is unknown. Realtek vendor drivers do a full hw re-initialization on each link-up event, the slimmed-down variant here was reported to fix the issue for the reporting user. It's not fully clear which parts of the NIC are reset as part of the software reset, therefore I can't rule out side effects. Fixes: f1bce4ad ("r8169: add support for RTL8125") Reported-by:

Breno Leitao says: ==================== net: netconsole: configfs entries for boot target There is a limitation in netconsole, where it is impossible to disable or modify the target created from the command line parameter. (netconsole=...). "netconsole" cmdline parameter sets the remote IP, and if the remote IP changes, the machine needs to be rebooted (with the new remote IP set in the command line parameter). This allows the user to modify a target without the need to restart the machine. This functionality sits on top of the dynamic target reconfiguration that is already implemented in netconsole. The way to modify a boot time target is creating special named configfs directories, that will be associated with the targets coming from `netconsole=...`. Example: Let's suppose you have two netconsole targets defined at boot time:: netconsole=4444@10.0.0.1/eth1,9353@10.0.0.2/12:34:56:78:9a:bc;4444@10.0.0.1/eth1,9353@10.0.0.3/12:34:56:78:9a:bc You can modify these targets in runtime by creating the following targets:: $ mkdir cmdline1 $ cat cmdline1/remote_ip 10.0.0.3 $ echo 0 > cmdline1/enabled $ echo 10.0.0.4 > cmdline1/remote_ip $ echo 1 > cmdline1/enabled ==================== Link: https://lore.kernel.org/r/20231012111401.333798-1-leitao@debian.orgSigned-off-by:

Enable the attachment of a dynamic target to the target created during boot time. The boot-time targets are named as "cmdline\d", where "\d" is a number starting at 0. If the user creates a dynamic target named "cmdline0", it will attach to the first target created at boot time (as defined in the `netconsole=...` command line argument). `cmdline1` will attach to the second target and so forth. If there is no netconsole target created at boot time, then, the target name could be reused. Relevant design discussion: https://lore.kernel.org/all/ZRWRal5bW93px4km@gmail.com/Suggested-by:

Breno Leitao authored
For netconsole targets allocated during the boot time (passing netconsole=... argument), netconsole_target->item is not initialized. That is not a problem because it is not used inside configfs. An upcoming patch will be using it, thus, initialize the targets with the name 'cmdline' plus a counter starting from 0. This name will match entries in the configfs later. Suggested-by:

Move alloc_param_target() and its counterpart (free_param_target()) to the bottom of the file. These functions are called mostly at initialization/cleanup of the module, and they should be just above the callers, at the bottom of the file. From a practical perspective, having alloc_param_target() at the bottom of the file will avoid forward declaration later (in the following patch). Nothing changed other than the functions location.

strncpy() is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. `desc` is expected to be NUL-terminated as evident by the manual NUL-byte assignment. Moreover, NUL-padding does not seem to be necessary. The only caller of efx_mcdi_nvram_metadata() is efx_devlink_info_nvram_partition() which provides a NULL for `desc`: | rc = efx_mcdi_nvram_metadata(efx, partition_type, NULL, version, NULL, 0); Due to this, I am not sure this code is even reached but we should still favor something other than strncpy. Considering the above, a suitable replacement is `strscpy` [2] due to the fact that it guarantees NUL-termination on the destination buffer without unnecessarily NUL-padding.

Let's also opt to use the more idiomatic strscpy() usage of (dest, src, sizeof(dest)) rather than (dest, src, SOME_LEN). Typically the pattern of 1) allocate memory for string, 2) copy string into freshly-allocated memory is a candidate for kmemdup_nul() but in this case we are allocating the entirety of the `res` struct and that should stay as is.

driver_state is a flex array, but is always allocated by the tls core to a fixed size (TLS_DRIVER_STATE_SIZE_{TX,RX}). Simplify the code by making that size explicit so that sizeof(struct tls_offload_context_{tx,rx}) works. Signed-off-by:Sabrina Dubroca <sd@queasysnail.net> Signed-off-by:

chcr_ktls uses the space reserved in driver_state by tls_set_device_offload, but makes up into own wrapper around tls_offload_context_tx instead of accessing driver_state via the __tls_driver_ctx helper. In this driver, driver_state is only used to store a pointer to a larger context struct allocated by the driver. Signed-off-by:
