[PATCH 1/2] ima: Fix warning: no previous prototype for function 'ima_add_kexec_buffer'

[PATCH 1/2] ima: Fix warning: no previous prototype for function 'ima_add_kexec_buffer'

[Lakshmi Ramasubramanian]

The function prototype for ima_add_kexec_buffer() is present
in 'linux/ima.h'.  But this header file is not included in
ima_kexec.c where the function is implemented.  This results
in the following compiler warning when "-Wmissing-prototypes" flag
is turned on:

  security/integrity/ima/ima_kexec.c:81:6: warning: no previous prototype
  for function 'ima_add_kexec_buffer' [-Wmissing-prototypes]

Include the header file 'linux/ima.h' in ima_kexec.c to fix
the compiler warning.

Fixes: dce92f6b11c3 (arm64: Enable passing IMA log to next kernel on kexec)

[PATCH 2/2] ima: Fix warning: no previous prototype for function 'ima_post_key_create_or_update'

[Lakshmi Ramasubramanian]

The function prototype for ima_post_key_create_or_update() is present
in 'linux/ima.h'.  But this header file is not included in
ima_asymmetric_keys.c where the function is implemented.  This results
in the following compiler warning when "-Wmissing-prototypes" flag
is turned on:

  security/integrity/ima/ima_asymmetric_keys.c:29:6: warning: no previous
  prototype for 'ima_post_key_create_or_update' [-Wmissing-prototypes]

Include the header file 'linux/ima.h' in ima_asymmetric_keys.c to
fix the compiler warning.

Roberto posted an equivalent patch "[PATCH 4/5] ima: Include header
defining ima_post_key_create_or_update()" earlier this week.

Compiler warnings don't meet the requirements for stable -
Documentation/process/stable-kernel-rules.rst.

thanks,

Mimi
