* stand: Add support for 64-bit machines with 32-bit UEFI implementationsAhmad Khalifa2025-03-262-3/+3
| | | | | | | | | | | | | | Some machines have 64-bit capable cpus but are stuck on 32-bit uefi firmware. Add support for them by building a new "loader_ia32" with LOADER_DEFAULT_INTERP along with the 64-bit one. The loader can be disabled using MK_LOADER_IA32.

* loader: Increase buffer size to accommodate longer commandsAhmad Khalifa2025-03-261-2/+3
| | | | | | | | | | | | | | | | The longest command we have is "efi-autoresizecons". That combined with the two spaces before and after the command gives us a total of 23 characters including the null-terminator. Also move the two trailing spaces to their own pager_output call so they don't get truncated if the command is too long and increase the minimum string length to 20 in order to fix alignment issues caused by the increased buffer size.

* stand: module: unlink the entire tail when dependencies fail to loadKyle Evans2024-07-211-5/+26
| | | | | | | | | | | | | | | | | | | | | | | Assume you have loader configured to load linux64, which has a dependency on both linux_common and mqueuefs but neither the kernel nor kernel config in question have the mqueuefs module included. When the load command for linux64 fails to find mqueuefs, it will free both linux64 and linux_common as they were loaded first, but only linux64 gets removed from the module list. As a result, future traversals hit an easy use-after-free with linux_common. Fix it so that we unlink the entire tail of the list. Anything after the initially loaded module is, by definition, a dependency on the loaded module while we're still in the load command, so we can just discard the entire tail. If linux_common were loaded before linux64, it should not move to a position during this load where it would suddenly be missing from the view presented to the kernel.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By default only report unverified files at severity VE_WANT and above. This inlcudes *.conf but not *.hints, *.cookie or *.tgz which get VE_TRY as their severity. If Verbose is set to 0, then VerifyFlags should default to 0 too. Thus the combination of module_verbose=0 VE_VEBOSE=0 is sufficient to make the loader almost totally silent. When verify_prep has to find_manifest and it is verified ok return VE_NOT_CHECKED to verify_file so that it can skip repeating verify_fd Also add better debugging output for is_verified and add_verify_status. vectx handle compressed modules When verifying a compressed module (.ko.gz or .ko.bz2) stat() reports the size as -1 (unknown). vectx_lseek needs to spot this during closing - and just read until EOF is hit. Note: because of the way libsa's open() works, verify_prep will see the path to be verified as module.ko not module.ko.bz2 etc. This is actually ok, because we need a separate module.ko.bz2 entry so that the package can be verified, and the hash for module.ko is of the uncompressed file which is what vectx will see. Re-work local.trust.mk so site.trust.mk need only set VE_SIGN_URL_LIST (if using the mentioned signing server) interp.c: restrict interactive input Apply the same restrictions to interactive input as for unverified conf and hints files.

* base: Remove support for the VTOC8 partitioning schemeMarius Strobl2023-07-262-101/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | The removal of the sparc64 support in February 2020 obsoleted the VTOC8 partitioning scheme as no other FreeBSD platform makes use of it. Moreover, the code is bitrotting as nothing defines e. g. LOADER_VTOC8_SUPPORT any more and, thus, should go now, too. With this change, the following commits are reverted as far as VTOC8 is concerned and parts haven't already previously been deleted along with prior sparc64 removals: 094fcb157d4c98211899cf09d06e2cf19149b7e0 a7d366e9589c95feda6f3bc78c59c6355d51f126 ba8d50d08b9df4e8213f9a6997ff6792ecebcd9b The alignment example d9711c28efc4ec89ba5ea11f8fd63e9d0a7fc81b added to the VTOC8 section of gpart.8 is folded into the MBR one. This should finally conclude the deorbit of sparc64-specific bits. We had joy, we had fun we ran Unix on a Sun. But that source and the song of FreeBSD have all gone.

* loader: always install help filesMitchell Horne2023-02-031-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Address two issues with current help file logic: The existing condition prevents the common help file from being installed when there are no additional help files defined. This results in no loader.help on EFI platforms, for example. Second, due to the fact that we build and install multiple loader types, each successive install will clobber the previous loader.help. The result is that we could lose type-specific commands, or possibly list them in loaders that do not have such commands. Instead, give each loader type a uniquely named help file. The EFI loader will look for /boot/loader.help.efi, userboot will look for /boot/loader.help.userboot, etc. The interpreter variant has no effect on which help file is loaded. This leaves the old /boot/loader.help unused. Some credit for the final approach goes to Mathieu <sigsys@gmail.com> for their version of the fix in https://reviews.freebsd.org/D22951.
