2024-05-02string: Add additional __realloc_size() annotations for "dup" helpersKees Cook
Several other "dup"-style interfaces could use the __realloc_size() attribute. (As a reminder to myself and others: "realloc" is used here instead of "alloc" because the "alloc_size" attribute implies that the memory contents are uninitialized. Since we're copying contents into the resulting allocation, it must use "realloc_size" to avoid confusing the compiler's optimization passes.) Add KUnit test coverage where possible. (KUnit still does not have the ability to manipulate userspace memory.)

Most of seq_puts() usages are done with a string literal. In such cases, the length of the string car be computed at compile time in order to save a strlen() call at run-time. seq_putc() or seq_write() can then be used instead. This saves a few cycles.

2024-05-02Merge branch 'bnxt_en-updates-for-net-next'Jakub Kicinski
Michael Chan says: ==================== bnxt_en: Updates for net-next The first patch converts the sw_stats field in the completion ring structure to a pointer. This allows the group of completion rings using the same MSIX to share the same sw_stats structure. Prior to this, the correct completion ring must be used to count packets. The next four patches remove the RTNL lock when calling the RoCE driver for asynchronous stop and start during error recovery and firmware reset. The RTNL ilock is replaced with a private mutex used to synchronize RoCE register, unregister, stop, and start. The last patch adds VF PCI IDs for the 5760X chips. v2: Dropped patch #1 from v1.

2024-05-02bnxt_en: Optimize recovery path ULP locking in the driverKalesh AP
In the error recovery path (AER, firmware recovery, etc), the driver notifies the RoCE driver via ULP_STOP before the reset and via ULP_START after the reset, all under RTNL_LOCK. The RoCE driver can take a long time if there are a lot of QPs to destroy, so it is not ideal to hold the global RTNL lock. Rely on the new en_dev_lock mutex instead for ULP_STOP and ULP_START. For the most part, we move the ULP_STOP call before we take the RTNL lock and move the ULP_START after RTNL unlock. Note that SRIOV re-enablement must be done after ULP_START or RoCE on the VFs will not resume properly after reset. The one scenario in bnxt_hwrm_if_change() where the RTNL lock is already taken in the .ndo_open() context requires the ULP restart to be deferred to the bnxt_sp_task() workqueue.

2024-05-02bnxt_en: Add a mutex to synchronize ULP operationsKalesh AP
The current scheme relies heavily on the RTNL lock for all ULP operations between the L2 and the RoCE driver. Add a new en_dev_lock mutex so that the asynchronous ULP_STOP and ULP_START operations can be serialized with bnxt_register_dev() and bnxt_unregister_dev() calls without relying on the RTNL lock. The next patch will remove the RTNL lock from the ULP_STOP and ULP_START calls.

There is no need to call ULP_STOP and ULP_START before and after the L2 reset in bnxt_reset_task(). This L2 reset is done after detecting TX timeout, RX ring errors, or VF config changes.

2024-05-02bnxt_en: share NQ ring sw_stats memory with subringsEdwin Peer
On P5_PLUS chips and later, the NQ rings have subrings for RX and TX completions respectively. These subrings are passed to the poll function instead of the base NQ, but each ring carries its own copy of the software ring statistics. For stats to be conveniently accessible in __bnxt_poll_work(), the statistics memory should either be shared between the NQ and its subrings or the subrings need to be included in the ethtool stats aggregation logic. This patch opts for the former, because it's more efficient and less confusing having the software statistics for a ring exist in a single place. Before this patch, the counter will not be displayed if the "wrong" cpr->sw_stats was used to increment a counter.

2024-05-02mm/slub: remove the check for NULL kmalloc_cachesHyunmin Lee

However, new_kmalloc_cache() itself checks NULL kmalloc_cahces before cache creation. Therefore, the NULL check is not necessary in this function.

For SLAB the kmalloc caches needed to be created in ascending sizes in order. However, the constraint is not necessary anymore because SLAB has been removed and SLUB doesn't need to comply with the constraint. Thus, kmalloc 96 and 192 caches can be created after the other size kmalloc caches are created instead of checking every time to find their order to be created. Also, this change could prevent engineers from being confused by the removed constraint.

'/memory' nodes always have a 'reg' property, and therefore should have a unit-address with just plain hex (i.e. no commas). Fix all the arm64 '/memory' nodes. It's possible that some bootloader depends on /memory (arm32 ATAG to DT code does for example). If so, the memory node should be commented with that requirement.
