| | | | | | | | | | | | | Browseable is now set through LuCI per share, so remove it. Same with writeable (inverted synonym for read only). domain master and preferred master seem to be legacy settings for Windows 9x. encrypt passwords defaults to yes. Probably should not be disabled either. Also reordered alphabetically.

* dnsmasq: introduce config support for forced DHCP optionsJo-Philipp Wich2017-07-211-5/+9
| | | | | | | | | | | Introduce a new UCI list setting `list dhcp_option_force` which is available in sections of type `dnsmasq` and `dhcp`. The `dhcp_option_force` setting has the same semantics as `dhcp_option` but generates `dhcp-option-force` directives instead of `dhcp-option` ones in emitted native configuration.

* dnsmasq: make bind-dynamic 'non-wildcard' interfaces defaultKevin Darbyshire-Bryant2017-06-113-4/+6
| | | | | | | | | | | | | | | 'non-wildcard' interfaces enables dnsmasq's '--bind-dynamic' mode. This binds to interfaces rather than wildcard addresses *and* keeps track of interface comings/goings via a unique Linux api. Quoting dnsmasq's author "bind-dynamic (bind individual addresses, keep up with changes in interface config) ... On linux, there's actually no sane reason not to use --bind-dynamic, and it's only not the default for historical reasons." Let's change history, well on LEDE at least, and change the default!

* dnsmasq: add dhcp-script hook conditionallyHans Dedecker2017-06-092-2/+14
| | | | | | | | | | | | Commit b32689afd6a661339861086c669e15c936293cf8 added support for dhcp-script hook. Adding dhcp-script config option results into two instances of dnsmasq being run which triggered oom issues on platforms having low memory. The dnsmasq dhcp-script config option will now only be added if at least one of the dhcp, tftp, neigh hotplug dirs has a regular hotplug file or if the dhcpscript uci config option is specified.

| | | | | | | | | | | | | | | | | | | | | | easy-rsa v3 is now a single script. It expects a 'vars' configuration file which path can be set using easy-rsa options, environment variables or just looking in the current directory. The default usage would be: # cd /etc/easy-rsa # easy-rsa COMMAND [command-options] Following upstream changes, /etc/easy-rsa/pki replaces /etc/easy-rsa/keys directory. The default /etc/easy-rsa/pki dir is marked to be kept during upgrade (WARN: priv keys are saved in the system backup) /etc/easy-rsa/openssl.1.0.cnf is now marked as config file while index and serial got removed.

* dnsmasq: add dhcp-script hook for other packagesNick Brassel2017-05-263-5/+59
| | | | | | | | | | | | | Adds a script which acts as a hook for when dnsmasq creates/destroys a lease, or completes a TFTP file transfer. The hook loops through scripts in appropriate directories inside '/etc/hotplug.d', executing each one with the same arguments supplied by dnsmasq. In case dnsmasq is jailed by ujail the dhcp-script hook will not work as expected as ujail does not yet support executing a script within a jail.

CVE-2017-9078 https://secure.ucc.asn.au/hg/dropbear/rev/c8114a48837c - Security: Fix information disclosure with ~/.ssh/authorized_keys symlink. Dropbear parsed authorized_keys as root, even if it were a symlink. The fix is to switch to user permissions when opening authorized_keys A user could symlink their ~/.ssh/authorized_keys to a root-owned file they couldn't normally read. If they managed to get that file to contain valid authorized_keys with command= options it might be possible to read other contents of that file. This information disclosure is to an already authenticated user. Thanks to Jann Horn of Google Project Zero for reporting this.

* mac80211, hostapd: always explicitly set beacon intervalMatthias Schiffer2017-05-132-4/+3
| | | | | | | | | | | | | | | | One of the latest mac80211 updates added sanity checks, requiring the beacon intervals of all VIFs of the same radio to match. This often broke AP+11s setups, as these modes use different default intervals, at least in some configurations (observed on ath9k). Instead of relying on driver or hostapd defaults, change the scripts to always explicitly set the beacon interval, defaulting to 100. This also applies the beacon interval to 11s interfaces, which had been forgotten before. VIF-specific beacon_int setting is removed from hostapd.sh. Fixes FS#619.

* hostapd: fix reload frequency change patchAbhilash Tuse2017-05-032-7/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When sta is configured, hostapd receives 'stop' and 'update' command from wpa_supplicant. In the update command, hostapd gets sta parameters with which it configures ap. Problem is, with the default wireless configuration: mode:11g freq:2.4GHz channel:1 If sta is connected to 5GHz network, then ap does not work. Ideally with 340-reload_freq_change.patch hostapd should reload the frequency changes and start ap in 5GHz, but ap becomes invisible in the network. This issue can be reproduced with following /etc/config/wireless: config wifi-device radio0 option type mac80211 option channel 1 option hwmode 11g option path 'virtual/uccp420/uccwlan' option htmode 'none' config wifi-iface 'ap' option device 'radio0' option encryption 'none' option mode 'ap' option network 'ap' option ssid 'MyTestNet' option encryption none config wifi-iface 'sta' option device radio0 option network sta option mode sta option ssid TestNet-5G option encryption psk2 option key 12345 This change updates current_mode structure based on configured hw_mode received from wpa_supplicant.
