…nly/IPv6-only networks (#581) * DELIA-70624: updated to reset counters only if gateway is available for ipv6. Signed-off-by: Balaji Punnuru <Balaji_Punnuru@comcast.com> * DELIA-70624: Added debug in the script Signed-off-by: Balaji Punnuru <Balaji_Punnuru@comcast.com> * DELIA-70624: networkConnectionRecovery: presence-aware packet-loss recovery trigger Recovery now fires only when no routed IP stack has acceptable connectivity and at least one routed stack is at/above the reassociate tolerance. This fixes the IPv4-only / IPv6-only case where a stack with no default route left packetsLost at 0 and suppressed recovery. Also folded in reliability/logging fixes: - clear stale gwIp on the V6 test-hook path - guard packet-loss comparisons against unparseable ping output - emit SYST_WARN_GW100PERC_PACKETLOSS to the logs file on every run - ping the IPv4 default-route interface explicitly (ping -I) - log total ipv4/ipv6 packet loss when above threshold - simplify the trigger to anyGood/anyBad classification * DELIA-70624: networkConnectionRecovery: add log() helper and per-call packet-loss fix - Introduce a log() helper that prepends the timestamp and appends to $logsFile, and convert the timestamped echo call sites to use it. - Rename packetsLostipv4/packetsLostipv6 globals to ipv4PacketLoss/ipv6PacketLoss for clarity. - Reset the per-call packetLoss to "" at the top of checkPacketLoss and guard the packet-loss telemetry block with [ -n "$packetLoss" ], so a routeless or unparseable ping no longer reuses the other family's value or triggers integer-comparison errors. - Fix a "[" spacing bug in checkWifiDrvErrors. Telemetry markers and t2CountNotify calls are unchanged. * DELIA-70624: networkConnectionRecovery: log route/loss snapshot on state change Emit a "network state changed" line with the per-stack route-present flags and packet-loss values only when the snapshot differs from the previous run (persisted in /tmp/.ncr_laststate), so field logs capture every transition without printing on every run. Debugging aid for customer-site triage. * DELIA-70624: remove debug logging and make script POSIX/busybox-sh safe - Drop the temporary DEBUG_NCR field-debug logging; retain the "network state changed" transition log (now unprefixed). - checkWifiDrvErrors(): $dir already holds the full debugfs path, so remove the duplicated /sys/kernel/debug/ieee80211/ prefix from the log messages, and capture the cat exit status so the failure log reports the real status instead of the enclosing test's result. - Replace bashisms with POSIX/busybox-ash equivalents: source -> ., [[ =~ ]] -> case, [[ ]] -> [ ], and {1..9} -> explicit list (the brace form never expands under busybox ash, which had left the WIFIV_WARN_PL_20..90PERC packet-loss markers non-functional on target). - Minor whitespace cleanup in checkDnsFile(). * DELIA-70624: restore 100% packet-loss triage marker and fix marker case Reinstate the field-triage log marker for 100% packet loss that was lost when checkPacketLoss() moved to a tolerance-based recovery decision. The new log-only marker "100% Packet loss is observed on all routed IP stacks" fires when every routed IP stack shows exactly 100% loss. It is independent of WifiReassociateTolerance and does not alter the recovery/return path, so recovery behaviour is unchanged. Unlike the legacy dual-stack "...for both ipv4 and ipv6" print, it is also emitted correctly on IPv4-only and IPv6-only networks. Triage associates the old and new strings to the same 100%-packet-loss marker for trend continuity across images. Also capitalise the "Packet loss more than 10% observed" marker (was lowercase "packet loss ...") since triage marker matching is case-sensitive. --------- Signed-off-by: Balaji Punnuru <Balaji_Punnuru@comcast.com> Co-authored-by: Balaji Punnuru <Balaji_Punnuru@comcast.com>
