| | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. separating L2 tables (ARP, NDP) from the L3 routing tables 2. removing as much locking dependencies among these layers as possible to allow for some parallelism in the search operations 3. simplify the logic in the routing code, The most notable end result is the obsolescent of the route cloning (RTF_CLONING) concept, which translated into code reduction in both IPv4 ARP and IPv6 NDP related modules, and size reduction in struct rtentry{}. The change in design obsoletes the semantics of RTF_CLONING, RTF_WASCLONE and RTF_LLINFO routing flags. The userland applications such as "arp" and "ndp" have been modified to reflect those changes. The output from "netstat -r" shows only the routing entries. Quite a few developers have contributed to this project in the past: Glebius Smirnoff, Luigi Rizzo, Alessandro Cerri, and Andre Oppermann. And most recently: - Kip Macy revised the locking code completely, thus completing the last piece of the puzzle, Kip has also been conducting active functional testing - Sam Leffler has helped me improving/refactoring the code, and provided valuable reviews - Julian Elischer setup the perforce tree for me and has helped me maintaining that branch before the svn conversion
* Some libstand/bootp.c extension (written by Danny Braniss, slightlyluigi2008-12-051-0/+328
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | revised/modified by me) to store dhcp options into kenv variables, so the information is available to the boot loader and can be used to customize the boot process. The change is totally unintrusive, essentially made of a single function to be called while parsing a dhcp response, and a couple of tables to classify options. The values extracted from dhcp options are stored in the kenv environment in one of these forms: + options whose name and type is known are saved as dhcp.name = value (string, or number/ip addresses lists) + unknown options are assumed to be strings and saved as dhcp.option-NNN = "value" + options listed as '__INDIR' and sent on the wire as e.g. option unknown-252 "some.name=the actual value" are saved as some.name = "the actual value" + options listed as '__ILIST' and sent on the wire as e.g. option unknown-249 "a.b=foo bar; c.d= 123; e.f=done" are saved as multiple values a.b="foo bar" c.d="123" e.f="done" As you can see there is quite a bit of flexibility on what can be passed to the loader or the kernel. For the time being the vendor-specific table is mostly disabled, because there is no standard set of options for FreeBSD, and I don't know all the pxe-specific vendor options. Also, applications using libstand may live in memory-constrained environments, so it makes sense to keep these tables as small as possible, especially considering that one can generate arbitrary name=value pairs using site-specific options of type __INDIR or __ILIST (there are 4 __ILIST and 5 __INDIR in the table, numbered 246..249 and 250..254). Actually, considering that probably 75% of the standard dhcp options are totally useless, it might make sense to remove them as well. Submitted by: Danny Braniss MFC after: 4 weeks

| | | | | | | | | | | | | | | | | | | | | - 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.

* Fix logical bug in the bzip2 reading code, which results in bogus EIOsobomax2007-12-182-2/+48
| | | | | | | | | | | | | | | | | | | | | returned on a perfectly valid bzip2 stream whose decompressed size is multiple of read-ahead buffer size. Reproduce the problem is easy: create some power-of-two sized file (truncate -s 1m file will do), bzip2 it and try to load it as md_image from loader. See how it fails. The bug doesn't affect gzip code (which most of bzip2-reading code was copied from) probably due to the fact that libgzip doesn't report Z_STREAM_END with the last block, but requires extra call to inflate() to retrieve it and has some extra data in the input stream at that time. However, apply similar fix to gzipfs.c just in the case the API will change in the future to do what bzip2 code does. Add some ifdef'ed code to enable testing bzipfs.c from witin normal FreeBSD environment as opposed to the restricted loader one, so that one can use gdb and whatnot.

* First cut at support for booting a GPT labeled disk via the BIOS bootstrapjhb2007-10-241-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | on i386 and amd64 machines. The overall process is that /boot/pmbr lives in the PMBR (similar to /boot/mbr for MBR disks) and is responsible for locating and loading /boot/gptboot. /boot/gptboot is similar to /boot/boot except that it groks GPT rather than MBR + bsdlabel. Unlike /boot/boot, /boot/gptboot lives in its own dedicated GPT partition with a new "FreeBSD boot" type. This partition does not have a fixed size in that /boot/pmbr will load the entire partition into the lower 640k. However, it is limited in that it can only be 545k. That's still a lot better than the current 7.5k limit for boot2 on MBR. gptboot mostly acts just like boot2 in that it reads /boot.config and loads up /boot/loader. Some more details: - Include uuid_equal() and uuid_is_nil() in libstand. - Add a new 'boot' command to gpt(8) which makes a GPT disk bootable using /boot/pmbr and /boot/gptboot. Note that the disk must have some free space for the boot partition. - This required exposing the backend of the 'add' function as a gpt_add_part() function to the rest of gpt(8). 'boot' uses this to create a boot partition if needed. - Don't cripple cgbase() in the UFS boot code for /boot/gptboot so that it can handle a filesystem > 1.5 TB. - /boot/gptboot has a simple loader (gptldr) that doesn't do any I/O unlike boot1 since /boot/pmbr loads all of gptboot up front. The C portion of gptboot (gptboot.c) has been repocopied from boot2.c. The primary changes are to parse the GPT to find a root filesystem and to use 64-bit disk addresses. Currently gptboot assumes that the first UFS partition on the disk is the / filesystem, but this algorithm will likely be improved in the future. - Teach the biosdisk driver in /boot/loader to understand GPT tables. GPT partitions are identified as 'disk0pX:' (e.g. disk0p2:) which is similar to the /dev names the kernel uses (e.g. /dev/ad0p2). - Add a new "freebsd-boot" alias to g_part() for the new boot UUID.

* - Given that we tell the compiler that struct ip is packed and 32-bitmarius2007-10-211-4/+4
| | | | | | | | | | | | | | | | | aligned, GCC 4.2.1 also generates code for sendudp() that assumes this alignment. GCC 4.2.1 however doesn't 32-bit align wbuf, causing the loader to crash due to an unaligned access of wbuf in sendudp() when netbooting sparc64. Solve this by specifying wbuf as packed and 32-bit aligned, too. As for lastdata and readudp() this currently is no issue when compiled with GCC 4.2.1, though give lastdata the same treatment as wbuf for consistency and possibility of being affected in the future.

| | | | | | | | | | | | | since otherwise the initial seek offset will contain the directory offset of the filesystem block that contained its directory entry. This bug was mostly harmless because typically the directory is less than one filesystem block in size so the offset would be zero.

Also reset the seek pointer when a new inode is opened in read_inode(), though this is not actually necessary now because all callers set it afterwards.
