Evgeny 6717c863e7 etcp_router: Ed25519 digital signature for service messages
- Add ed25519_public_key[32] to NODEINFO struct for pubkey distribution
- Add ed25519_public_key[32] to ROUTE_BGP (derived from X25519 privkey at init)
- Add ROUTER_FLAG_SIGNED (0x08) to SVC_ROUTE_HDR flags byte
- router_send_one_flags: when is_signed, sign [hdr][payload] and append 64-byte sig
- etcp_router_recv_cb: verify Ed25519 signature when ROUTER_FLAG_SIGNED set
- New API: etcp_router_conn_send_signed()
- Drop signed packets if sender node not in routing table or no Ed25519 key
- 5 unit tests in test_etcp_router_unit.c covering OK/tampered/unknown/no-key/short

.SH NAME
mdb_copy \- LMDB environment copy tool
.SH SYNOPSIS
.B mdb_copy
[\c
.BR \-V ]
[\c
.BR \-c ]
[\c
.BR \-n ]
.B srcpath
[\c
.BR dstpath ]
.SH DESCRIPTION
The
.B mdb_copy
utility copies an LMDB environment. The environment can
be copied regardless of whether it is currently in use.
No lockfile is created, since it gets recreated at need.
If
.I dstpath
is specified it must be the path of an empty directory
for storing the backup. Otherwise, the backup will be
written to stdout.
.SH OPTIONS
.TP
.BR \-V
Write the library version number to the standard output, and exit.
.TP
.BR \-c
Compact while copying. Only current data pages will be copied; freed
or unused pages will be omitted from the copy. This option will
slow down the backup process as it is more CPU-intensive.
Currently it fails if the environment has suffered a page leak.
.TP
.BR \-n
Open LDMB environment(s) which do not use subdirectories.
.SH DIAGNOSTICS
Exit status is zero if no errors occur.
Errors result in a non-zero exit status and
a diagnostic message being written to standard error.
.SH CAVEATS
This utility can trigger significant file size growth if run
in parallel with write transactions, because pages which they
free during copying cannot be reused until the copy is done.
