Rick Macklem 69527b11bb The problem report was for a crash that happened when smbfs was ... trying to do a mount. Given the backtrace, it appears that the crash occurred when smb_vc_create() failed and then called smb_vc_put() with vcp->vc_iod == NULL. smb_vc_put() subsequently called smb_vc_disconnect() with vcp->vc_iod == NULL, causing the crash. This patch adds a check for vcp->vc_iod != NULL in smb_vc_disconnect() to avoid the crash. It also fixes the case in smb_vc_create() where kproc_create() fails so that it destroys the mutexes and sets vcp->vc_iod == NULL before free()'ing the iod structure. The person who reported the PR tested the patch, but was not able to reproduce the crash with or without the patch. PR: 201912 Reviewed by: jhb MFC after: 2 weeks		2015-11-18 23:04:01 +00:00
