MFC 246417,247116,248584:
Rework the handling of stop signals in the NFS client. The changes in
195702, 195703, and 195821 prevented a thread from suspending while holding
locks inside of NFS by forcing the thread to fail sleeps with EINTR or
ERESTART but defer the thread suspension to the user boundary. However,
this had the effect that stopping a process during an NFS request could
abort the request and trigger EINTR errors that were visible to userland
processes (previously the thread would have suspended and completed the
request once it was resumed).
This change instead effectively masks stop signals while in the NFS client.
It uses the existing TDF_SBDRY flag to effect this since SIGSTOP cannot
be masked directly. Instead of setting PBDRY on individual sleeps, change
the VFS_*() and VOP_*() methods to defer stop signals for filesystems which
request this behavior via a new VFCF_SBDRY flag. Note that this has to be
a VFC flag rather than a MNTK flag so that it works properly with
VFS_MOUNT() when the mount is not yet fully constructed. For now, only the
NFS clients set this new flag in VFS_SET().
A few other related changes:
- Add an assertion to ensure that TDF_SBDRY doesn't leak to userland.
- When a lookup request uses VOP_READLINK() to follow a symlink, mark
the request as being on behalf of the thread performing the lookup
(cnp_thread) rather than using a NULL thread pointer. This causes
NFS to properly handle signals during this VOP on an interruptible
mount.
- Ignore thread suspend requests due to SIGSTOP if stop signals are
currently deferred. This can occur if a process is stopped via
SIGSTOP while a thread is running or runnable but before it has set
TDF_SBDRY.
