...same problem with all the attached files...
...
I attached all the matching files.
More infos:
- checking build system type... sparc-sun-solaris2.9
- checking host system type... sparc-sun-solaris2.9
- checking for non-GNU ld... /usr/ucb/ld
- checking if the linker (/usr/ucb/ld) is GNU ld... no
- checking for /usr/ucb/ld option to reload object files... -r
- SunOS protee 5.9 Generic sun4u sparc SUNW,Sun-Blade-100
- Compiler: /opt/SUNWspro/bin/cc
If it helps and that you need more information, don't hesitate to ask me...
Regards.

* The sonode represents a socket. A sonode never exist in the file system
* name space and can not be opened using open() - only the socket, socketpair
* and accept calls create sonodes.
*
* When an AF_UNIX socket is bound to a pathname the sockfs
* creates a VSOCK vnode in the underlying file system. However, the vnodeops
* etc in this VNODE remain those of the underlying file system.
* Sockfs uses the v_stream pointer in the underlying file system VSOCK node
* to find the sonode bound to the pathname. The bound pathname vnode
* is accessed through so_ux_vp.
*
* A socket always corresponds to a VCHR stream representing the transport
* provider (e.g. /dev/tcp). This information is retrieved from the kernel
* socket configuration table and entered into so_accessvp. sockfs uses
* this to perform VOP_ACCESS checks before allowing an open of the transport
* provider.
*
* The locking of sockfs uses the so_lock mutex plus the SOLOCKED
* and SOREADLOCKED flags in so_flag. The mutex protects all the state
* in the sonode. The SOLOCKED flag is used to single-thread operations from
* sockfs users to prevent e.g. multiple bind() calls to operate on the
* same sonode concurrently. The SOREADLOCKED flag is used to ensure that
* only one thread sleeps in kstrgetmsg for a given sonode. This is needed
* to ensure atomic operation for things like MSG_WAITALL.
*
* Note that so_lock is sometimes held across calls that might go to sleep
* (kmem_alloc and soallocproto*). This implies that no other lock in
* the system should be held when calling into sockfs; from the system call
* side or from strrput. If locks are held while calling into sockfs
* the system might hang when running low on memory.

* The counts (so_oobcnt and so_oobsigcnt) track the number of
* urgent indicates that are (logically) queued on the stream head
* read queue. The urgent data is queued on the stream head
* as follows.
*
* In the normal case the SIGURG is not generated until
* the T_EXDATA_IND arrives at the stream head. However, transports
* that have an early indication that urgent data is pending
* (e.g. TCP receiving a "new" urgent pointer value) can send up
* an M_PCPROTO/SIGURG message to generate the signal early.
*
* The mark is indicated by either:
* - a T_EXDATA_IND (with no M_DATA b_cont) with MSGMARK set.
* When this message is consumed by sorecvmsg the socket layer
* sets SS_RCVATMARK until data has been consumed past the mark.
* - a message with MSGMARKNEXT set (indicating that the
* first byte of the next message constitutes the mark). When
* the last byte of the MSGMARKNEXT message is consumed in
* the stream head the stream head sets STRATMARK. This flag
* is cleared when at least one byte is read. (Note that
* the MSGMARKNEXT messages can be of zero length when there
* is no previous data to which the marknext can be attached.)
*
* While the T_EXDATA_IND method is the common case which is used
* with all TPI transports, the MSGMARKNEXT method is needed to
* indicate the mark when e.g. the TCP urgent byte has not been
* received yet but the TCP urgent pointer has made TCP generate
* the M_PCSIG/SIGURG.
*
* The signal (the M_PCSIG carrying the SIGURG) and the mark
* indication can not be delivered as a single message, since
* the signal should be delivered as high priority and any mark
* indication must flow with the data. This implies that immediately
* when the SIGURG has been delivered if the stream head queue is
* empty it is impossible to determine if this will be the position
* of the mark. This race condition is resolved by using MSGNOTMARKNEXT
* messages and the STRNOTATMARK flag in the stream head. The
* SIOCATMARK code calls the stream head to wait for either a
* non-empty queue or one of the STR*ATMARK flags being set.
* This implies that any transport that is sending M_PCSIG(SIGURG)
* should send the appropriate MSGNOTMARKNEXT message (which can be
* zero length) after sending an M_PCSIG to prevent SIOCATMARK
* from sleeping unnecessarily.
