From 2cc89f6da424ab503af563e0cc92dda43b8f8432 Mon Sep 17 00:00:00 2001 From: dimitri staessens Date: Mon, 29 Aug 2016 19:49:39 +0200 Subject: lib: Refactor shm_du_map to shm_rdrbuff The shm_du_map is renamed to shm_rdrbuff to reflect the Random Deletion Ringbuffer used in the implementation. The close_on_exit call is removed and SDUs are cleaned up by the application in the ap_fini() call. This required a non-blocking peek() operation in the shm_ap_rbuff. Some initial implementation for future support of qos cubes has been added to the shm_rdrbuff. --- src/ipcpd/local/main.c | 19 ++++++++++++------- 1 file changed, 12 insertions(+), 7 deletions(-) (limited to 'src/ipcpd/local') diff --git a/src/ipcpd/local/main.c b/src/ipcpd/local/main.c index 547e7e28..4fa7e33f 100644 --- a/src/ipcpd/local/main.c +++ b/src/ipcpd/local/main.c @@ -24,7 +24,7 @@ #include "ipcp.h" #include "flow.h" #include -#include +#include #include #include #include @@ -67,7 +67,7 @@ struct ipcp * _ipcp; /* the shim needs access to these internals */ struct shim_ap_data { pid_t api; - struct shm_du_map * dum; + struct shm_rdrbuff * rdrb; struct bmp * fds; struct shm_ap_rbuff * rb; @@ -98,8 +98,8 @@ static int shim_ap_init() return -1; } - _ap_instance->dum = shm_du_map_open(); - if (_ap_instance->dum == NULL) { + _ap_instance->rdrb = shm_rdrbuff_open(); + if (_ap_instance->rdrb == NULL) { bmp_destroy(_ap_instance->fds); free(_ap_instance); return -1; @@ -107,7 +107,7 @@ static int shim_ap_init() _ap_instance->rb = shm_ap_rbuff_create(); if (_ap_instance->rb == NULL) { - shm_du_map_close(_ap_instance->dum); + shm_rdrbuff_close(_ap_instance->rdrb); bmp_destroy(_ap_instance->fds); free(_ap_instance); return -1; @@ -139,8 +139,13 @@ void shim_ap_fini() if (_ap_instance->fds != NULL) bmp_destroy(_ap_instance->fds); - if (_ap_instance->dum != NULL) - shm_du_map_close_on_exit(_ap_instance->dum); + + /* remove all remaining sdus */ + while ((i = shm_ap_rbuff_peek_idx(_ap_instance->rb)) >= 0) + shm_rdrbuff_remove(_ap_instance->rdrb, i); + + if (_ap_instance->rdrb != NULL) + shm_rdrbuff_close(_ap_instance->rdrb); if (_ap_instance->rb != NULL) shm_ap_rbuff_destroy(_ap_instance->rb); -- cgit v1.2.3
