* dropbear: add ed25519 for failsafe keyEtienne Champetier2023-07-261-2/+3
| | | | | | | | | | | | At least Fedora and RHEL 9 set RSAMinSize=2048, so when trying to use failsafe, we get 'Bad server host key: Invalid key length' To workaround the issue, we can use: ssh -o RSAMinSize=1024 ... Generating 2048 bits RSA is extremely slow, so add ed25519. We keep RSA 1024 to be as compatible as possible.

* treewide: add support for "lto" in PKG_BUILD_FLAGSAndre Heider2023-03-211-3/+2
| | | | | | | | | | | | | | | | This reduces open coding and allows to easily add a knob to enable it treewide, where chosen packages can still opt-out via "no-lto". Some packages used LTO, but not the linker plugin. This unifies 'em all to attempt to produce better code. Quoting man gcc(1): "This improves the quality of optimization by exposing more code to the link-time optimizer." Also use -flto=auto instead of -flto=jobserver, as it's not guaranteed that every buildsystem uses +$(MAKE) correctly. Signed-off-by: Andre Heider <a.heider@gmail.com>
* treewide: add support for "gc-sections" in PKG_BUILD_FLAGSAndre Heider2023-03-211-3/+3
| | | | | | | | | | | | | | | This reduces open coding and allows to easily add a knob to enable it treewide, where chosen packages can still opt-out via "no-gc-sections". Note: libnl, mbedtls and opkg only used the CFLAGS part without the LDFLAGS counterpart. That doesn't help at all if the goal is to produce smaller binaries. I consider that an accident, and this fixes it. Note: there are also packages using only the LDFLAGS part. I didn't touch those, as gc might have been disabled via CFLAGS intentionally.

* build: introduce $(MKHASH)Leonardo Mörlein2021-05-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, it was assumed that mkhash is in the PATH. While this was fine for the normal build workflow, this led to some issues if make TOPDIR="$(pwd)" -C "$pkgdir" compile was called manually. In most of the cases, I just saw warnings like this: make: Entering directory '/home/.../package/gluon-status-page' bash: line 1: mkhash: command not found bash: line 1: mkhash: command not found bash: line 1: mkhash: command not found bash: line 1: mkhash: command not found bash: line 1: mkhash: command not found bash: line 1: mkhash: command not found bash: line 1: mkhash: command not found bash: line 1: mkhash: command not found [...] While these were only warnings and the package still compiled sucessfully, I also observed that some package even fail to build because of this. After applying this commit, the variable $(MKHASH) is introduced. This variable points to $(STAGING_DIR_HOST)/bin/mkhash, which is always the correct path.

* dropbear: roll up recipes into mapping listsKonstantin Demin2020-12-111-24/+59
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | this commit removes manual recipes for options and introduces mapping lists: - DB_OPT_COMMON holds option mappings which are common for all builds; - DB_OPT_CONFIG holds option mappings which are depend on config settings. DB_OPT_COMMON is space-separated list of 'words', each of them is in format: 'header_option|value' 'header_option' is added with value 'value' to 'localoptions.h'. if 'header_option' is preceded by two exclamation marks ('!!') then option is not added to 'localoptions.h' but replaced in 'sysoptions.h'. in short: option|value - add option to localoptions.h !!option|value - replace option in sysoptions.h DB_OPT_CONFIG is space-separated list of 'words', each of them is in format: 'header_option|config_variable|value_enabled|value_disabled' 'header_option' is handled likewise in DB_OPT_COMMON. if 'config_variable' is enabled (technically: not disabled) then 'header_option' is set to 'value_enabled' and 'value_disabled' otherwise. in short: option|config|enabled|disabled = add option to localoptions.h !!option|config|enabled|disabled = replace option in sysoptions.h option := (config) ? enabled : disabled If you're not sure that option's value doesn't have '|' within - add your recipe manually right after '$(Build/Configure/dropbear_headers)' and write some words about your decision. PS about two exclamation marks: early idea was to use one exclamation mark to denote such header options but then i thought single exclamation mark may be overlooked by mistake.

* dropbear: Enable Ed25519 for normal devicesPaul Spooren2020-09-062-3/+4
| | | | | | | | | | | | | | | | | | | | The Ed25519 key pairs are much shorter than RSA pairs and are supported by default in OpenSSH. Looking at websites explaining how to create new SSH keys, many suggest using Ed25519 rather than RSA, however consider the former as not yet widely established. OpenWrt likely has a positive influence on that development. As enabling Ed25519 is a compile time option, it is currently not possible to install the feature via `opkg` nor select that option in an ImageBuilder. Due to the size impact of **12kB** the option should only be enabled for devices with `!SMALL_FLASH`. This approach seems cleaner than splitting `dropbear` into two packages like `dropbear` and `dropbear-ed25519`. Signed-off-by: Paul Spooren <mail@aparcar.org>

* dropbear: make rsa-sha2-256 pubkeys usable againPetr Štetiar2020-07-071-0/+40
| | | | | | | | | | | | | Upstream in commit 972d723484d8 ("split signkey_type and signature_type for RSA sha1 vs sha256") has added strict checking of pubkey algorithms which made keys with SHA-256 hashing algorithm unusable as they still reuse the `ssh-rsa` public key format. So fix this by disabling the check for `rsa-sha2-256` pubkeys.

* procd: Add wrapper for uci_validate_section()Jeffery To2019-01-221-7/+4
| | | | | | | | | | | | | | | | | This adds a wrapper (uci_load_validate) for uci_validate_section() that allows callers (through a callback function) to access the values set by uci_validate_section(), without having to manually declare a (potentially long) list of local variables. The callback function receives two arguments when called, the config section name and the return value of uci_validate_section(). If no callback function is given, then the wrapper exits with the value returned by uci_validate_section(). This also updates several init scripts to use the new wrapper function.

| | | | | | | | | | | | | | | Interface triggers are installed by the dropbear init script in case an interface is configured for a given dropbear uci section. As dropbear is started after network the interface trigger event can be missed during a small window; this is especially the case if lan is specified as interface.

As dropbear is started earlier than netifd add a boot function to avoid the usage of network.sh functions as call to such functions will fail at boottime.

* dropbear: close all active clients on shutdownChristian Schoenebeck2018-07-161-0/+5
| | | | | | | | | | | | | | | | | | | | Override the default shutdown action (stop) and close all processes of dropbear Since commit 498fe85, the stop action only closes the process that's listening for new connections, maintaining the ones with existing clients. This poses a problem when restarting or shutting-down a device, because the connections with existing SSH clients, like OpenSSH, are not properly closed, causing them to hang. This situation can be avoided by closing all dropbear processes when shutting-down the system, which closes properly the connections with current clients.
