NL_SET_ERR_MSG_MOD inserts the KBUILD_MODNAME and a ':' before the actual extended error message. The devlink feature hasn't been able to be compiled as a module since commit f4b6bcc7 ("net: devlink: turn devlink into a built-in"). Stop using NL_SET_ERR_MSG_MOD, and just use the base NL_SET_ERR_MSG. This aligns the extended error messages better with the NL_SET_ERR_MSG_ATTR messages as well. Signed-off-by:

In the previous code, TX timestamp accuracy was bad because the irq handler got the timestamp from the timestamp register at that time. This hardware has "Timestamp capture" feature which can store each TX timestamp into the timestamp descriptors. To improve TX timestamp accuracy, implement timestamp descriptors' handling.

In the previous code, the gptp flag was completely related to the !dir_tx in struct rswitch_gwca_queue because rswitch_gwca_queue_alloc() was called below: < In rswitch_txdmac_alloc() > err = rswitch_gwca_queue_alloc(ndev, priv, rdev->tx_queue, true, false, TX_RING_SIZE); So, dir_tx = true, and gptp = false. < In rswitch_rxdmac_alloc() > err = rswitch_gwca_queue_alloc(ndev, priv, rdev->rx_queue, false, true, RX_RING_SIZE); So, dir_tx = false, and gptp = true. In the future, a new queue handling for timestamp will be implemented and this gptp flag is confusable. So, remove the gptp flag. Signed-off-by:

The kernel maintains three markers for the MDB dump: 1. The last bridge device from which the MDB was dumped. 2. The last MDB entry from which the MDB was dumped. 3. The last port-group entry that was dumped. Add test cases for large scale MDB dump to make sure that all the configured entries are dumped and that the markers are used correctly. Specifically, create 2 bridges with 32 ports and add 256 MDB entries in which all the ports are member of. Test that each bridge reports 8192 (256 * 32) permanent entries. Do that with IPv4, IPv6 and L2 MDB entries. On my system, MDB dump of the above is contained in about 50 netlink messages. Example output: # ./bridge_mdb.sh [...] INFO: # Large scale dump tests TEST: IPv4 large scale dump tests [ OK ] TEST: IPv6 large scale dump tests [ OK ] TEST: L2 large scale dump tests [ OK ] [...] Signed-off-by:

Future patches are going to move parts of the bridge MDB code to the common rtnetlink code in preparation for VXLAN MDB support. To facilitate code sharing between both drivers, move the validation of the top level attributes in RTM_{NEW,DEL}MDB messages to a policy that will eventually be moved to the rtnetlink code. Use 'NLA_NESTED' for 'MDBA_SET_ENTRY_ATTRS' instead of NLA_POLICY_NESTED() as this attribute is going to be validated using different policies in the underlying drivers. Signed-off-by: -

The purpose of the sequence generation counter in the netlink callback is to identify if a multipart dump is consistent or not by calling nl_dump_check_consistent() whenever a message is generated. The function is not invoked by the MDB code, rendering the sequence generation counter assignment pointless. Remove it. Note that even if the function was invoked, we still could not accurately determine if the dump is consistent or not, as there is no sequence generation counter for MDB entries, unlike nexthop objects, for example.

To get useful results from the Memory Sanitizer, all code running in a process needs to be instrumented. When building tests with other sanitizers, it's not strictly necessary, but is also helpful.

Memory Sanitizer requires passing different options to CFLAGS and LDFLAGS: besides the mandatory -fsanitize=memory, one needs to pass header and library paths, and passing -L to a compilation step triggers -Wunused-command-line-argument. So introduce a separate variable for linker flags. Use $(SAN_CFLAGS) as a default in order to avoid complicating the ASan usage. Signed-off-by:

skbuff_head_cache is misnamed (perhaps for historical reasons?) because it does not hold heads. Head is the buffer which skb->data points to, and also where shinfo lives. struct sk_buff is a metadata structure, not the head. Eric recently added skb_small_head_cache (which allocates actual head buffers), let that serve as an excuse to finally clean this up :) Leave the user-space visible name intact, it could possibly be uAPI.

Alex Elder says: ==================== net: ipa: prepare for GSI register updtaes An upcoming series (or two) will convert the definitions of GSI registers used by IPA so they use the "IPA reg" mechanism to specify register offsets and their fields. This will simplify implementing the fairly large number of changes required in GSI registers to support more than 32 GSI channels (introduced in IPA v5.0). A few minor problems and inconsistencies were found, and they're fixed here. The last three patches in this series change the "ipa_reg" code to separate the IPA-specific part (the base virtual address, basically) from the generic register part, and the now- generic code is renamed to use just "reg_" or "REG_" as a prefix rather than "ipa_reg" or "IPA_REG_". ==================== Signed-off-by: -
