-Subject: autofs-5.1.7 - use default stack size for threads
|
|
|
-
|
|
|
-autofs uses PTHREAD_STACK_MIN to set the stack size for threads it
|
|
|
-creates.
|
|
|
-
|
|
|
-In two cases it is used to reduce the stack size for long running
|
|
|
-service threads while it's used to allocate a larger stack for worker
|
|
|
-threads that can have larger memory requirements.
|
|
|
-
|
|
|
-In recent glibc releases PTHREAD_STACK_MIN is no longer a constant
|
|
|
-which can lead to unexpectedly different stack sizes on different
|
|
|
-architectures and the autofs assumption it's a constant causes a
|
|
|
-compile failure.
|
|
|
-
|
|
|
-The need to alter the stack size was due to observed stack overflow
|
|
|
-which was thought to be due the thread stack being too small for autofs
|
|
|
-and glibc alloca(3) usage.
|
|
|
-
|
|
|
-Quite a bit of that alloca(3) usage has been eliminated from autofs now,
|
|
|
-particularly those that might be allocating largish amounts of storage,
|
|
|
-and there has been a lot of change in glibc too so using the thread
|
|
|
-default stack should be ok.
