| 18 | |
| 19 | Security fix: |
| 20 | * make-secnet-sites: Don't allow setting new VPN-level properties |
| 21 | when restricted. This could allow denial of service by |
| 22 | users with delegated authorisation. [Mark Wooding] |
| 23 | |
| 24 | Bugfixes for poor network environments: |
| 25 | * polypath: cope properly with asymmetric routing, by correcting |
| 26 | the handling of late duplicated packets etc. Protocol is now |
| 27 | incompatible with secnet prior to 0.3.0 when either end is mobile. |
| 28 | * Randomise key setup retry time. |
| 29 | |
| 30 | Other bugfixes: |
| 31 | * rsa and cbcmac: Fix configuration error messages. [Mark Wooding] |
| 32 | * Handle IPv4 addresses properly (ie, not foolishly byte-swapped), |
| 33 | when IPv6 is not available. [Mark Wooding] |
| 34 | * Better logging (and less foolish debug), especially about whether |
| 35 | key is set up, and about crossed key setup attempts. |
| 36 | * Internal refactoring and fixes. [Ian Jackson and Mark Wooding] |
| 37 | |
| 38 | Build system and portability: |
| 39 | * configure: rerun autogen.sh with autoconf 2.69-10 |
| 40 | * Avoid memset(0,0,0) wrt st->sharedsecret. (Fixes compiler warning; |
| 41 | in theory might cause miscompilation.) [Mark Wooding] |
| 42 | |
| 43 | Documentation: |
| 44 | * README.make-secnet-sites: new documentation file. [Mark Wooding] |
| 45 | * NOTES: Describe current allocation of capability bits. [Mark Wooding] |
| 46 | * NOTES: tiny fix tot protocol description. |
| 47 | * secnet(8): Delete wrong information about dh groups. [Mark Wooding] |
| 48 | |
| 49 | Administrivia: |
| 50 | * Fix erroneous GPL3+ licence notices "version d or later" (!) |
| 51 | * .dir-locals.el: Settings for Python code. [Mark Wooding] |

| 57 | Security improvement: |
| 58 | * Use `mpz_powm_sec' for modexps. |
| 59 | |
| 60 | Enhancements: |
| 61 | * Implement comm-info and dedicated-interface-addr feature, for |
| 62 | benefit of hippotat. |
| 63 | * Implement `keepalive' site option, to try to keep link always up. |
| 64 | |
| 65 | Build etc. fixes: |
| 66 | * #include <limits.h> (fixes the build on jessie). |
| 67 | * Tolerate building from a git checkout, but with git not installed. |
| 68 | (This can happen in chroots.) |
| 69 | * Turn off -Wsign-compare for bison output. |
| 70 | * Makefile.in: Fix `check-ipaddrset' rule to get reference from |
| 71 | $(srcdir). (Makes out-of-tree builds work properly.) |
| 72 | * Release checklist fixes. |
| 73 | * Burn version numbers 0.4.1 and 0.4.2 due to errors in release prep. |
| 74 | |
| 75 | Bugfixes: |
| 76 | * When printing messages about dropping IPv6, do not print anything |
| 77 | about ihl. (Check the IP version field first!) |
| 78 | * When turning on debug, turn on verbose too. |

| 104 | * Install ipaddrset.py and secnet.8 with correct permissions. |
| 105 | * Fix check for <linux/if_tun.h> and git rid of our copy. |
| 106 | * Use -lresolv only if inet_aton is not found otherwise. |
| 107 | * Use -lnsl only if inet_ntoa is not found otherwise. |
| 108 | * debian/rules: Provide build-arch and build-indep targets. |

| 112 | Copyright updates: |

| 114 | * Get rid of old FSF street address; use URL instead. |
| 115 | * Remove obsolete LICENCE.txt (which was for snprintf reimplementation). |
| 116 | * Remove obsolete references to Cendio (for old ipaddr.py). |

| 120 | secnet (0.4.0~beta1) unstable; urgency=low |
| 121 | |
| 122 | New features: |
| 123 | * Support transport over IPv6. (We do not yet carry IPv6 in the private |
| 124 | network.) IPv6 support depends on IPv6-capable adns (adns 1.5.x). |
| 125 | * New polypath comm, which can duplicate packets so as to send them via |
| 126 | multiple routes over the public network, for increased |
| 127 | reliability/performance (but increased cost). Currently Linux-only |
| 128 | but should be fairly easy to port. |
| 129 | * Support multiple public addresses for peers. |
| 130 | * Discard previously-received packets (by default). |
| 131 | |
| 132 | Logging improvements: |
| 133 | * Report (each first) transmission and reception success and failure. |
| 134 | * Log reason for DNS reolution failure. |
| 135 | * Log unexpected kinds of death from userv. |
| 136 | * Log authbind exit status as errno value (if appropriate). |
| 137 | |
| 138 | Configuration adjustments: |
| 139 | * Adjust default number of mobile peer addresses to store when a peer |
| 140 | public address is also configured. |
| 141 | * Make specifying peer public port optional. This avoids making special |
| 142 | arrangements to bind to a port for in mobile sites with no public |
| 143 | stable address. |
| 144 | |
| 145 | Bugfixes: |
| 146 | * Hackypar children will die if they get a terminating signal. |
| 147 | * Fix signal dispositions inherited by secnet's child processes. |
| 148 | * Fix off-by-one error which prevented setting transport-peers-max to 5. |
| 149 | |
| 150 | Test, build and internal improvements: |
| 151 | * Use conventional IP address handling library ipaddr.py. |
| 152 | * Provide a fuzzer for the slip decoder. |
| 153 | * Build system improvements. |
| 154 | * Many source code cleanups. |

| 171 | * Fix a memory leak in some error logging. |
| 172 | |
| 173 | Other related fixes: |
| 174 | * Two other latent bugs in buffer length handling found and fixed. |
| 175 | * Non-critical stylistic improvements to buffer length handling, to make |

| 180 | secnet (0.3.3~beta1) unstable; urgency=low |
| 181 | |
| 182 | Installation compatibility fix: |

| 184 | incompatible modern ipaddr.py is installed (eg via python-ipaddr.deb). |
| 185 | (Future versions of secnet are going to need that Python module to be |
| 186 | installed.) |
| 187 | |
| 188 | For links involving mobile sites: |
| 189 | * Use source of NAK packets as hint for peer transport address. |
| 190 | * When initiating rekey, make use of data transport peer addresses. |

| 193 | * Provide clean target in test-example/Makefile. |
