Martin Schwidefsky 1277580fe5 [S390] vdso: clock_gettime of CLOCK_THREAD_CPUTIME_ID with noexec=on ... The combination of noexec=on and a clock_gettime call with clock id CLOCK_THREAD_CPUTIME_ID is broken. The vdso code switches to the access register mode to get access to the per-cpu data structure to execute the magic ectg instruction. After the ectg instruction the code always switches back to the primary mode but for noexec=on the correct mode is the secondary mode. The effect of the bug is that the user space program looses the access to all mappings without PROT_EXEC, e.g. the stack. The problem is fixed by restoring the mode that has been active before the switch to the access register mode. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>		2009-07-24 12:41:02 +02:00
