wpa_supplicant_remove_iface() removes the P2P management interface from the global interfaces list before calling wpa_supplicant_deinit_iface(). When wpas_p2p_group_remove() is called from wpa_supplicant_deinit_iface(), the P2P group created on the calling wpa_s was not getting cleared as the calling wpa_s is not in the list of global->ifaces. This results in the P2P management interface being removed without disconnecting the p2p_group created on it. This could result in an illegal access of freed memory, e.g., when a pending eloop task wpas_p2p_reconsider_moving_go() was triggered with the leftover ctx pointer to the removed P2P interface instance. Fix this by disconnecting the P2P group created on interface to be deinitialized before deinitializing the interface. Signed-off-by: Veerendranath Jakkam <vjakkam@codeaurora.org> |

wpa_supplicant and hostapd -------------------------- Copyright (c) 2002-2019, Jouni Malinen <j@w1.fi> and contributors All Rights Reserved. These programs are licensed under the BSD license (the one with advertisement clause removed). If you are submitting changes to the project, please see CONTRIBUTIONS file for more instructions. This package may include either wpa_supplicant, hostapd, or both. See README file respective subdirectories (wpa_supplicant/README or hostapd/README) for more details. Source code files were moved around in v0.6.x releases and compared to earlier releases, the programs are now built by first going to a subdirectory (wpa_supplicant or hostapd) and creating build configuration (.config) and running 'make' there (for Linux/BSD/cygwin builds).
