Roberto Sassu 4e8581eefe ima: pass filename to ima_rdwr_violation_check() ... ima_rdwr_violation_check() retrieves the full path of a measured file by calling ima_d_path(). If process_measurement() calls this function, it reuses the pointer and passes it to the functions to measure/appraise/audit an accessed file. After commit bc15ed663e ("ima: fix ima_d_path() possible race with rename"), ima_d_path() first tries to retrieve the full path by calling d_absolute_path() and, if there is an error, copies the dentry name to the buffer passed as argument. However, ima_rdwr_violation_check() passes to ima_d_path() the pointer of a local variable. process_measurement() might be reusing the pointer to an area in the stack which may have been already overwritten after ima_rdwr_violation_check() returned. Correct this issue by passing to ima_rdwr_violation_check() the pointer of a buffer declared in process_measurement().
