Subject: [PATCH] x86/fpu: Fix invalid FPU ptrace state after execve()
|
||||
|
||||
commit b22cbe404a9cc3c7949e380fa1861e31934c8978 upstream.
|
||||
|
||||
Robert O'Callahan reported that after an execve PTRACE_GETREGSET
|
||||
NT_X86_XSTATE continues to return the pre-exec register values
|
||||
until the exec'ed task modifies FPU state.
|
||||
|
||||
The test code is at:
|
||||
|
||||
https://bugzilla.redhat.com/attachment.cgi?id=1164286.
|
||||
|
||||
What is happening is fpu__clear() does not properly clear fpstate.
|
||||
Fix it by doing just that.
