Subject: tomoyo: add missing call to cap_bprm_set_creds
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b1338d199dda6681d9af0297928af0a7eb9cba7b;p=linux-beck.git

tomoyo: add missing call to cap_bprm_set_creds

cap_bprm_set_creds() has to be called from security_bprm_set_creds().
TOMOYO forgot to call cap_bprm_set_creds() from tomoyo_bprm_set_creds()
and suid executables were not being working.

Make sure we call cap_bprm_set_creds() with TOMOYO, to set credentials
properly inside tomoyo_bprm_set_creds().
