Subject: [PATCH 0/2] net/ice: fix memory handling issues
Date: Wed,  7 Oct 2026 07:58:18 +0000	[thread overview]
Message-ID: <cover.1791356190.git.anurag.mandal@intel.com> (raw)

This patch series addresses two memory handling issues in the ice PMD.

- The first one makes memory allocation and release symmetric. 
  Several buffers obtained through ice_malloc(), ice_calloc() 
  or ice_memdup() were released with rte_free() instead of ice_free(). 
  Both APIs currently map to the same underlying allocator. 
  However, mixing them is inconsistent and would break if the OS 
  abstraction layer ever changes.

- The second one fixes an unchecked allocation in ice_tx_queue_start() 
  which dereferences the Tx time queue context buffer returned by 
  ice_malloc() without NULL check.
  On allocation failure, the E830 send-on-timestamp path therefore crashes
  instead of reporting "No Memory" error, and also the already allocated
  txq_elem buffer gets leaked.

  net/ice: free memory with matching allocator
