Subject [PATCH] crypto: rsa - fix a potential race condition in build
|
|
Date Fri, 2 Dec 2016 15:41:04 -0800
|
|
|
|
|
|
When building kernel with RSA enabled with multithreaded, the below
|
|
compile failure might be caught:
|
|
|
|
| /buildarea/kernel-source/crypto/rsa_helper.c:18:28: fatal error: rsapubkey-asn1.h: No such file or directory
|
|
| #include "rsapubkey-asn1.h"
|
|
| ^
|
|
| compilation terminated.
|
|
| CC crypto/rsa-pkcs1pad.o
|
|
| CC crypto/algboss.o
|
|
| CC crypto/testmgr.o
|
|
| make[3]: *** [/buildarea/kernel-source/scripts/Makefile.build:289: crypto/rsa_helper.o] Error 1
|
|
| make[3]: *** Waiting for unfinished jobs....
|
|
| make[2]: *** [/buildarea/kernel-source/Makefile:969: crypto] Error 2
|
|
| make[1]: *** [Makefile:150: sub-make] Error 2
|
|
| make: *** [Makefile:24: __sub-make] Error 2
|
|
|
|
The header file is not generated before rsa_helper is compiled, so
|
|
adding dependency to avoid such issue.
