* discover: Add DEVICE_TYPE_ANY for matching any deviceJeremy Kerr2014-01-303-1/+5
| | | | | | | | | | Currently, If we want disable all but a specific device type from default boot, we need to add a negative priority for all other devices. This change adds a DEVICE_TYPE_ANY definition, to allow a simpler way to express "only boot a specific type" by default behaviour. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* discover: Make boot_priorities more flexibleJeremy Kerr2014-01-305-9/+30
| | | | | | | | | | | | Rather than rely on the ordering of the boot_priorities array to define which device types have a higher "default boot" priority, this change introduces a slightly more flexible way of priority lookups, by adding a separate priority field to struct boot_priority. This means we can have an unordered array, change priorities without re-writing the array, and implementing a disable mechanism. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* discover/network: Use platform definition for DHCP architecture IDJeremy Kerr2014-01-304-2/+18
| | | | | | | Allow a platform to specify a DHCP architecture ID, as this is platform-specific. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* platforms/powerpc: Check for a powerpc platform in the probe functionJeremy Kerr2014-01-301-0/+15
| | | | | | | | | | Currently, we're always assuming a powerpc platform, as the powerpc probe() function always returns true. This change adds a check for some bits we need to work on a powerpc platform. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* pb-config: Move config storage modules to "platform" modules in discover codeJeremy Kerr2014-01-3017-337/+288
| | | | | | | | | | | | | | | | | | There's no need to include the config storage code in lib/ as only the discover server should be using it. This change moves the config-storage code to discover/, with the platform-specific parts moved to a 'struct platform'. Each platform has a probe function, which is called during init. The first probe function to return a platform is used. At present we only have the one platform, but it's now non-intrusive to add others. We keep an array of platform pointers in a separate ("platforms") section, to allow the test module to drop-in its own test "platform". Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* lib/pb-config: Add config_copyJeremy Kerr2014-01-303-2/+68
| | | | | | | | | | | | | | At the moment, UIs have the config_set_defaults function to estabilish an initial configuration when performing an update. Rather than using the defaults, this change provides a config_copy() function, so that the updated configuration can be initialised from the current config. With this in place, the UI/server-common pb-config module can be reduced to just the one function. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* test/parser: Add Fedora 20 ppc64 parser testcaseJeremy Kerr2014-01-303-0/+54

* discover/grub2: Add support for for-loopsJeremy Kerr2014-01-303-0/+55
| | | | | | | | | GRUB2 syntax allows for for-loops; this change adds supoprt in the parser grammar and script execution code to implement them. In the execution code, we simply update the for-loop variable and re-execute the body statements. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* discover/grub2: Perform word-expansion non-destructivelyJeremy Kerr2014-01-301-99/+83
| | | | | | | | | | | | | | | In order to implement for-loops, we may need to evaluate the same chunk of script more than once, and perform that evaluation in a different context (particularly, with different environment variables). Currently, the process_expansion code destroys the result of the parse-tree (ie, the token list) when performing expansions. This means that we can only perform the expansions once. This change preserves the token list while creating the argv array. This means that we can expand the list multiple times. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* discover: Add support for checking directories in parser APIJeremy Kerr2014-01-305-0/+75
| | | | | | | | | | | | | This change adds a function to the parser API: int parser_check_dir(struct discover_context *ctx, struct discover_device *dev, const char *dirname) - which allows parsers to check for the presence of a directory (path of 'dirname') on the device ('dev'). We use this in the GRUB2 parser to implement the `test -d` check. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* discover/grub2: skip menuentries that don't define a boot optionJeremy Kerr2014-01-301-0/+3
| | | | | | | | | | menuentries may perform arbitrary commands; we only want ones that define a boot option. This change doesn't add a boot option if we haven't seen at least a boot image defined in the menuentry. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* discover/grub: Add feature variable for --id support.Jeremy Kerr2014-01-301-0/+3
| | | | | | | Since we support --id arguments on menuentries, add the corresponding feature variable. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* discover/grub2: Use script_env_set when initialising the environmentJeremy Kerr2014-01-301-6/+2
| | | | | | | | | | No need to duplicate the environment-adding code in init_env, as we can just use script_env_set. Since script_env_set does its own talloc, we don't need to talloc our strings here either. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* pb-config/powerpc: fix default option handlingJeremy Kerr2014-01-231-10/+30
| | | | | | | | | | | Currently, we don't update nvram if an NVRAM parameter is set to the default. This means we can never revert a configuration to its default value. This change fixes the default setting behaviour; instead of checking for a default, we want to check if it's a default and the option is absent. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* discover: Use lowercase hex chars for MAC-address-based conf requestsJeremy Kerr2014-01-224-2/+42
| | | | | | | The de-facto PXELINUX standard specifies lowercase characters for the MAC addresses, so change our reuqests to suit. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* lib/process: Add helper for check process clean exitJeremy Kerr2014-01-214-6/+15
| | | | | | | We have a few incorrect checks for the exit status of a process; this change adds a helper with the correct WIFEXITED && WEXITSTATUS==0 logic. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* discover/paths: Check process exit status when loading URLsJeremy Kerr2014-01-211-1/+4
| | | | | | | | | | Currently, we may report incorrect success when loading a URL, as we only check the return value of process_run_sync() (and not the process exit status itself) in load_process_to_local_file. This fix adds a check to the synchronous load. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* utils/hooks: Add dtb-sort hookJeremy Kerr2014-01-211-0/+12
| | | | | | | The boot hooks may have altered the DTB in various ways, so add a final (90-) boot hook to re-sort the dtb with `dtc -s`. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* utils/pb-udhcpc: Unify references to DHCP bootfile parameterJeremy Kerr2014-01-212-10/+12
| | | | | | | | | | | | | | udhcpc may pass the bootfile parameter as either $bootfile or $boot_file, depending on whether the option is present in the BOOTP header, or as a DHCP vendor option. We have code in pb-udhcpc to unify this to $bootfile, but we only use the unified value in one of the user events. This change uses the correct value of bootfile, and fixes the check to conditionally generate the explicit add event. We also need to update the user-event code to use the right event parameter name. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* utils/pb-udhcpc: Fix incorrect reference to $interfaceJeremy Kerr2014-01-201-2/+2
| | | | | | | | We have a typo in the udhcpc hook, where we're not referncing the interface variable correctly. This means we'll get the same device identifier for all netboot options. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* utils/pb-udhcpc: remove bashism when reading mac addressJeremy Kerr2014-01-201-1/+1
| | | | | | | The $(< FILE) syntax we use to read an interface's MAC address doesn't work in dash or busybox sh. Instead, use cat. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>

* discover: Support DHCP "pathprefix" configuration optionJeremy Kerr2014-01-177-37/+177
| | | | | | | | | | | | | | | | | This change implements support for the DHCP "pathprefix" option. We use the following logic: - If pathprefix is present and a full URL, we base the config file location on pathprefix + conffile - If pathprefix is present but not a full URL, we use it as the path component of the URL, and pick up the host from other parameters in the DHCP response - If no pathprefix is present, we determine the configuration prefix from the DHCP bootfile parameter. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* test/parser: Check for full URLs in parser testsJeremy Kerr2014-01-178-12/+24
| | | | | | | | | | | | At present, we only match the 'file' portion of a URL in the parser tests, so we "serve" a file if just the filename (but not the scheme, hostname or path) matches the file we set with test_read_conf_embedded. This change introduces test_read_conf_embedded_url, which we can use to specify a full URL. In this case, the fake parser_request_file matches the entire URL before returning the file data. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* discover: Don't rely on ctx->conf_url side-effect in user_event_parse_conf_urlJeremy Kerr2014-01-173-5/+11
| | | | | | | | Currently, user_event_parse_conf_url sets dc->conf_url if it detects we have a full URL (rather than a base URL). This is a little too subtle, so replace it with an explicit output parameter. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* discover/grub: Use --id values for default option detectionBen Stoltz2014-01-173-7/+53
| | | | | | | | Fix Petitboot's grub.cfg parser to handle --id=label argument to menuentry, and use it (in preference to the option name) when looking for a default option. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* discover: Bring down configured interfaces on discover server exit.Jeremy Kerr2014-01-172-1/+7
| | | | | | | | We want to down the interfaces that we brought up, so hook up the network_shutdown function to the discover exit path. Also, we only want to down interfaces that we've configured, and exclude lo. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* utils: Add boot hook to set stdout property on DT machinesJeremy Kerr2014-01-151-0/+23
| | | | | | | | | On machines that use device-tree boot, they'll often set an early console, defined by the linux,stdout property in the /chosen/ device tree node. This hook adds a facility for petitboot to set this, based on an NVRAM setting.
* discover: we need stderr for the BusyBox TFTP type checkJeremy Kerr2014-01-141-0/+1
| | | | | | | Busybox tftp doesn't support -V, so prints an error to stderr. We'll only see the Busybox identifier if we capture stderr too. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* lib/process: Add add_stderr flag to process moduleJeremy Kerr2014-01-145-1/+118
| | | | | | | | | | | | For some process execution functions, we'd like to capture stderr as well as stdout. Currently, we unconditionally redirect subprocess stderr to the petitboot log file. This change adds an add_stderr flag to struct process, which indicates to the process library that we want stderr as well as stdout. If this is specified, the subprocess' stderr is captured to stdout_buf. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* test/parser: Add yaboot leftovers testJeremy Kerr2014-01-142-0/+36
| | | | | | | Add a test to ensure that boot option parameters don't leak into later options. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* discover/yaboot: Remove known_names listJeremy Kerr2014-01-141-26/+2
| | | | | | | | | | | The known_names list only duplicates the arg matching we do in the body of the parser, and so introduces a problem when the array becomes out of sync. We drop the priority of the "unknown name" messages to pb_debug, as this isn't really imporant unless we're debugging. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* discover/yaboot: Clear globals_done when we see an image definitionJeremy Kerr2014-01-143-3/+33
| | | | | | | | | | Currently, we have a bug where a 'known_name' that appears before an image section will cause globals_done to be set, and we don't see any further global variables. This change sets globals_done only once we see an image section. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>

* config/powerpc: Always call update_network_configJeremy Kerr2013-12-231-2/+1
| | | | | | | | | | | | | | Currently, we have a bug when setting the default network configuration (ie, no devices have any specific config), as we won't call update_network_config to clear out the value of the petitboot,network parameter. This change always invokes update_network_config, regardless of the number of interfaces configured. This ensures we clear out the petitboot,network param, which is then synced to nvram if the param has changed. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses/nc-config: Add validation for network settingsJeremy Kerr2013-12-181-9/+30
| | | | | | | Use the new widget validators, plus a bit of whole-form logic, to implement some basic validation on the config UI. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses/nc-widgets: Add initial textbox validation functionsJeremy Kerr2013-12-182-0/+68
| | | | | | | | | We'd like to do some validation of the system configuration parameters, so add a few validation types to the widget code. We currently need integer, ipv4 address and multiple ipv4 address types. These are implemented as small wrappers around the ncurses form validator code. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses/nc-config: expand mask fieldJeremy Kerr2013-12-181-1/+1
| | | | | | This makes it obvious if there's more than two characters in the field. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* configure: Use AC_GNU_SOURCEJeremy Kerr2013-12-1833-44/+54
| | | | | | | Rather than #defining _GNU_SOURCE in our .c files, we can define this from config.h instead. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>

* sysinfo: Add interface link status to sysinfo dataJeremy Kerr2013-12-185-14/+38
| | | | | | | | This changes adds a 'link' parameter to the interface information sent in sysinfo messages. The discover network code populates this from the incoming netlink messages. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* test/lib: Add parent stdout testJeremy Kerr2013-12-182-0/+56

* discover/yaboot: Fix assertion failure on empty yaboot filesJeremy Kerr2013-12-103-1/+15
| | | | | | | | | | yaboot configuration files with no option will cause an assertion failure (or segfault), as we unconditionally call yaboot_finish(). Check for the presence of an option in yaboot_finish() instead of asserting. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* discover/boot: Copy local paths before running boot hooksJeremy Kerr2013-12-051-13/+22
| | | | | | | | | | | We're seeing a crash when boot hooks are specifying new resources, as boot_hook_update_param will write to a NULL struct load_url_result. Instead of writing the updated values to the struct, copy the local parts of the result to a separate string, which the boot hooks are free to update. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* discover/boot: Fix condition for updating boot paramsJeremy Kerr2013-12-051-5/+3
| | | | | | | | In commit 823958fb, we change to use struct process, but left in the check for rc == BOOT_HOOK_EXIT_UPDATE. We actually want to check process->exit_status here, not rc. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* discover/udev: Use UUIDs for multipath checkJeremy Kerr2013-12-051-9/+14

* ui/ncurses/boot-editor: Fix (null) when non-device resources are shownJeremy Kerr2013-12-031-1/+1
| | | | | | | | | | | We're seeing the following in the boot editor: image: (null)ftp://... the (null) is due to the sep in conditional_prefix, which should be blank, not NULL. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* discover/grub2: Fixes for bison 3.xJeremy Kerr2013-12-032-7/+7
| | | | | | | | | | YYLEX_PARAM is removed in bison 3.0, so we need to pass the scanner param directly through yyparse (rather than referencing parser->scanner). Unfortunately, we don't have the lexer header available at the time we declare yyparse, so we need to pass a void * here. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
