- Revision 1.156 marked ptrace() SMP safe. Unfortunately, alpha implements

parts of ptrace using proc_rwmem(). proc_rwmem() requires giant, and giant must be acquired prior to the proc lock, so ptrace must require giant still.

Update the statfs structure with 64-bit fields to allow

accurate reporting of multi-terabyte filesystem sizes. You should build and boot a new kernel BEFORE doing a `make world' as the new kernel will know about binaries using the old statfs structure, but an old kernel will not know about the new system calls that support the new statfs structure. Running an old kernel after a `make world' will cause programs such as `df' that do a statfs system call to fail with a bad system call.

Mark ptrace(), ktrace(), utrace(), sysarch(), and issetugid() as MP safe.

The parts of these calls that are not yet MP safe acquire Giant explicitly.

o Remove TDF_NOSIGPOST. o Add a member td_waitset to proc structure, it will be used for sigwait. Tested by: deischen

or unblock a thread in kernel, and allow UTS to specify whether syscall should be restarted. o Add ability for UTS to monitor signal comes in and removed from process, the flag PS_SIGEVENT is used to indicate the events. o Add a KMF_WAITSIGEVENT for KSE mailbox flag, UTS call kse_release with this flag set to wait for above signal event. o For SA based thread, kernel masks all signal in its signal mask, let UTS to use kse_thr_interrupt interrupt a thread, and install a signal frame in userland for the thread. o Add a tm_syncsig in thread mailbox, when a hardware trap occurs, it is used to deliver synchronous signal to userland, and upcall is schedule, so UTS can process the synchronous signal for the thread.

Add system calls to explicitly list extended attributes on a

file/directory/link, rather than using a less explicit hack on the extattr retrieval API: extattr_list_fd() extattr_list_file() extattr_list_link() The existing API was counter-intuitive, and poorly documented. The prototypes for these system calls are identical to extattr_get_*(), but without a specific attribute name to leave NULL.
