Subject: [dpdk-dev] [PATCH v10 1/3] lib/lpm: integrate RCU QSBR
Date: Fri, 10 Jul 2020 10:22:25 +0800
Message-ID: <20200710022227.103963-2-ruifeng.wang@arm.com> (raw)
In-Reply-To: <20200710022227.103963-1-ruifeng.wang@arm.com>

Currently, the tbl8 group is freed even though the readers might be
using the tbl8 group entries. The freed tbl8 group can be reallocated
quickly. This results in incorrect lookup results.

RCU QSBR process is integrated for safe tbl8 group reclaim.
Refer to RCU documentation to understand various aspects of
integrating RCU library into other libraries.

To avoid ABI breakage, a struct __rte_lpm is created for lpm library
internal use. This struct wraps rte_lpm that has been exposed and
also includes members that don't need to be exposed such as RCU related
config.

 Prefix expansion is one of the keys of this algorithm,
 since it improves the speed dramatically by adding redundancy.
 
+Deletion
+~~~~~~~~
+
+When deleting a rule, a replacement rule is searched for. Replacement rule is an existing rule that has
+the longest prefix match with the rule to be deleted, but has shorter prefix.
+
+If a replacement rule is found, target tbl24 and tbl8 entries are updated to have the same depth and next hop
+value with the replacement rule.
+
+If no replacement rule can be found, target tbl24 and tbl8 entries will be cleared.
+
+Prefix expansion is performed if the rule's depth is not exactly 24 bits or 32 bits.
+
+After deleting a rule, a group of tbl8s that belongs to the same tbl24 entry are freed in following cases:
+
+*   All tbl8s in the group are empty .
+
+*   All tbl8s in the group have the same values and with depth no greater than 24.
+
+Free of tbl8s have different behaviors:
+
+*   If RCU is not used, tbl8s are cleared and reclaimed immediately.
+
+*   If RCU is used, tbl8s are reclaimed when readers are in quiescent state.
+
+When the LPM is not using RCU, tbl8 group can be freed immediately even though the readers might be using
+the tbl8 group entries. This might result in incorrect lookup results.
+
+RCU QSBR process is integrated for safe tbl8 group reclamation. Application has certain responsibilities
+while using this feature. Please refer to resource reclamation framework of :ref:`RCU library <RCU_Library>`
+for more details.
