[upstream commit 606bc42] I realized we used camelCase in a tetra subcmd and in the debug API. Changing the debug API should not be a problem as it was not yet released and it's a debug feature. The subcmd has an alias because it was easy. Signed-off-by: Mahe Tardy <mahe.tardy@gmail.com>
[upstream commit 8b2aa36] This allows the command to return != 0 return error code on failure as expected. Signed-off-by: Mahe Tardy <mahe.tardy@gmail.com>
[upstream commit 69ea3f8] When dumping a full process cache (around 65K entries) the gRPC client could not handle a response of this size. This makes it possible to configure it on demand if needed. Signed-off-by: Mahe Tardy <mahe.tardy@gmail.com>
[upstream commit 7e4b379] When running ./tetra dump processcache we can get all processes in the user-space process cache. Out of these, we can use --skip-zero-refcnt to exclude processes with refCnt equals to 0. These are processes that will be removed from the processCache soon. Out of these processes with refCnt not equal to 0, most of them are nornal running processes that also exist in the execve_map. This patch adds another command line option --exclude-execve-map-processes that excludes processes that exist in the execve_map. The remaining processes (if any) have possibly an error in the reference counting. Signed-off-by: Anastasios Papagiannis <tasos.papagiannnis@gmail.com>
