Pass NCP_PATH_STD to ncp_ns_alloc_short_dir_handle() when the AFP Entry ID
smoke test allocates a temporary directory handle for a VOL: path.
The test already uses libncp to allocate the handle, but it passed the raw
"SYS:" bytes together with an explicit byte length. ncpfs helpers expect
NCP_PATH_STD when the caller wants libncp to encode a normal NetWare path into
the component-counted wire format. Sending the raw VOL: string made the server
reject the handle allocation with completion 0x98 before the AFP endpoint was
reached.
Keep the libncp handle allocation path, but let libncp encode the root volume
path the same way the ncpfs tools do. This changes only the Linux smoke test;
server AFP protocol behavior is unchanged.
Use libncp\047s namespace-aware short directory handle helper in the AFP Entry ID smoke test instead of hand-building the old Allocate Temporary Directory Handle request.\n\nThe smoke test accepts NetWare-style VOL:PATH arguments, but NCP 0x23/0x0c AFP Get Entry ID From Path Name expects a directory handle plus a relative path. The previous test tried to allocate a temporary handle by issuing the old NCP 0x16/0x13 request directly, which failed with Invalid Path before the AFP endpoint was reached.\n\nMirror the ncpfs tools and call ncp_ns_alloc_short_dir_handle() for the volume root in the DOS namespace, then pass only the relative path to the AFP request. Keep deallocating the temporary handle after the request.\n\nThis changes only the Linux smoke test; server AFP protocol behavior is unchanged.
Teach the Linux AFP Entry ID smoke test to treat VOL:PATH arguments like normal NetWare paths instead of sending the full string as the AFP path component.
The WebSDK documents AFP Get Entry ID From Path Name as taking a NetWare directory handle plus a path string. A user-supplied path such as SYS:PUBLIC therefore needs a directory handle for the SYS volume root and a relative AFP path of PUBLIC; sending SYS:PUBLIC as the AFP path with directory handle zero makes the server reject the request with Invalid Path before the actual AFP lookup is useful.
Use the existing ncpfs/libncp request path to allocate a temporary directory handle for the volume root when the test receives a VOL:PATH argument and no explicit --dir-handle was supplied. Keep --raw-path for callers that want to send the path exactly as typed, and add --allow-invalid-path so negative path-resolution tests can distinguish Invalid Path from Invalid Namespace.
Also add failure diagnostics to the server-side AFP path lookup so unsupported-backend, boundary-check, path-resolution, and stat failures are visible in the mars_nwe log.
This changes only the Linux smoke test and debug logging; it does not change successful AFP protocol semantics.
Add an optional Linux-side smoke test for the first implemented NetWare AFP endpoint.
The WebSDK documents NCP 0x2222/35/12 AFP Get Entry ID From Path Name as taking a NetWare directory handle and path string and returning a 32-bit AFP entry id. MARS-NWE now has a guarded implementation of that probe when the optional Netatalk/libatalk backend is compiled in, but exercising it does not require a real AppleTalk workstation.
Use the ncpfs/libncp client library as the test transport. ncpfs is commonly available on Linux mars_nwe test hosts and its NWRequestSimple() helper builds the same length-prefixed subfunction request format used by normal libncp callers. The test accepts standard ncpfs connection options such as -S, -U, -P, and -n, sends NCP 0x23/0x0c, and prints the returned entry id.
Keep the test out of normal builds behind MARS_NWE_BUILD_LINUX_TESTS because it depends on host ncpfs development headers/library and on a running server. Add an --allow-invalid-namespace mode so builds without the Netatalk backend can still run a negative smoke test and verify that AFP remains unavailable.
This adds test infrastructure only and does not change server protocol behavior.
