* MFaltix:marcel2011-03-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Add support for Pre-Boot Virtual Memory (PBVM) to the loader. PBVM allows us to link the kernel at a fixed virtual address without having to make any assumptions about the physical memory layout. On the SGI Altix 350 for example, there's no usuable physical memory below 192GB. Also, the PBVM allows us to control better where we're going to physically load the kernel and its modules so that we can make sure we load the kernel in memory that's close to the BSP. The PBVM is managed by a simple page table. The minimum size of the page table is 4KB (EFI page size) and the maximum is currently set to 1MB. A page in the PBVM is 64KB, as that's the maximum alignment one can specify in a linker script. The bottom line is that PBVM is between 64KB and 8GB in size. The loader maps the PBVM page table at a fixed virtual address and using a single translations. The PBVM itself is also mapped using a single translation for a maximum of 32MB. While here, increase the heap in the EFI loader from 512KB to 2MB and set the stage for supporting relocatable modules.

* Remove file system support based on the simple file system protocolmarcel2010-01-094-446/+268
| | | | | | | | | | | | | | | | | | | | | | | as this only allows us to access file systems that EFI knows about. With a loader that can only use EFI-supported file systems, we're forced to put /boot on the EFI system partition. This is suboptimal in the following ways: 1. With /boot a symlink to /efi/boot, mergemaster complains about the mismatch and there's no quick solution. 2. The EFI loader can only boot a single version of FreeBSD. There's no way to install multiple versions of FreeBSD and select one at the loader prompt. 3. ZFS maintains /boot/zfs/zpool.cache and with /boot a symlink we end up with the file on a MSDOS file system. ZFS does not have proper handling of file systems that are under Giant. Implement a disk device based on the block I/O protocol instead and pull in file system code from libstand. The disk devices are really the partitions that EFI knows about. This change is backward compatible. MFC after: 1 week
* Enable GCC stack protection (aka Propolice) for userland:ru2008-06-251-0/+2
| | | | | | | | | | | | | | | | | | | | | - It is opt-out for now so as to give it maximum testing, but it may be turned opt-in for stable branches depending on the consensus. You can turn it off with WITHOUT_SSP. - WITHOUT_SSP was previously used to disable the build of GNU libssp. It is harmless to steal the knob as SSP symbols have been provided by libc for a long time, GNU libssp should not have been much used. - SSP is disabled in a few corners such as system bootstrap programs (sys/boot), process bootstrap code (rtld, csu) and SSP symbols themselves. - It should be safe to use -fstack-protector-all to build world, however libc will be automatically downgraded to -fstack-protector because it breaks rtld otherwise. - This option is unavailable on ia64. Enable GCC stack protection (aka Propolice) for kernel: - It is opt-out for now so as to give it maximum testing. - Do not compile your kernel with -fstack-protector-all, it won't work.

* Major rework of the ia64 loaders. The two primary objectives are:marcel2006-11-0514-1318/+530
| | | | | | | | | | | | | | 1. Make libefi portable by removing ia64 specific code and build it on i386 and amd64 by default to prevent regressions. These changes include fixes and improvements over previous code to establish or improve APIs where none existed or when the amount of kluging was unacceptably high. 2. Increase the amount of sharing between the efi and ski loaders to improve maintainability of the loaders and simplify making changes to the loader-kernel handshaking in the future. The version of the efi and ski loaders are now both changed to 1.2 as user visible improvements and changes have been made.

| | | | | | | | | | | | | | | things over floppy size limits, I can exclude it for release builds or something like that. Most of the changes are to get the load_elf.c file into a seperate elf32_ or elf64_ namespace so that you can have two ELF loaders present at once. Note that for 64 bit kernels, it actually starts up the kernel already in 64 bit mode with paging enabled. This is really easy because we have a known minimum feature set. Of note is that for amd64, we have to pass in the bios int 15 0xe821 memory map because once in long mode, you absolutely cannot make VM86 calls. amd64 does not use 'struct bootinfo' at all. It is a pure loader metadata startup, just like sparc64 and powerpc. Much of the infrastructure to support this was adapted from sparc64.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | accept load options (=command line options). The call graph changes from *entry*->efi_main->efi_init, where efi_main is the EFI equivalent of main to *entry*->efi_main->main, where main is what you'd expect. efi_main now is what efi_init was. The prototype of main follows that of C. The first argument is argc and the second is argv. There is no third argument. Allocation of heap pages is now handled by the EFI library and it now deallocates the pages when main() returns or when exit() is called. This allows us to safely return to the boot manager (or EFI shell) without leaks. EFI applications are responsible to free all memory themselves. Handling of the load options is a bit tricky. There are either no load options, load options in ASCII or load options in Unicode. The EFI library will translate the ASCII options to Unicode options as to simplify user code. Since the load options are passed as a single string (if present) and main() accepts argc and argv, the startup code also has to split the string into words and build the argv vector. Here the trickiness starts. When the loader is started from the EFI shell, argv[0] will automaticly load the program name. In all other cases (ie through the boot manager), this is not the case. Unfortunately, there's no trivial way to check. Hence, a set of conditions is checked to determine if we need to fill in argv[0] ourselves or not. This checking is not perfect. There are known cases where it fails to do the right thing. The logic works for most expected cases, though. This includes the case where no options are given. Approved by: re (blanket)
