2021-12-01Fix booting from an IDE block device on the Sun Blade 100. ApparentlyMark Kettenis
writing to disk using the Open Firmware interfaces is buggy and causes corruption of the disk. While it isn't entirely clear what versions of Open Firmware are affected, but it seems to only affect IDE drives. So if we detect an IDE drive, disable writing to it. This results in a small lose of bootloader functionality (bsd.upgrade loop prevention and flagging /etc/random.seed re-use) but that is better than losing the ability to run OpenBSD at all. Based on a diff by Ted Bullock (who did all the hard work of debugging this and coming up with a viable fix). ok deraadt@

2021-07-28Fix previous: In one spot I incorrectly used Pos (unsigned short) whereTheo Buehler
I should have used Byte (unsigned char) which led to passing twice the correct size to free. Found & tested by bluhm with the sys/netinet/ipsec tests on i386.
2021-07-22Add sizes for free() in zlibTheo Buehler
Rebased version of a diff from miod who described it as follows: This tries to keep diffability against upstream, hence a questionable choice of the size type for zcfree() - but all sizes should fit in 32 bits anyway. Since all zcfree routines used in the tree cope with NULL arguments (including the various alloc.c used by the boot blocks), I have simplified TRY_FREE to compensate for the growth.

2021-07-20Remove unneeded __sync_* library functions from the kernel.Visa Hankala
These library functions were added as stopgaps because GCC 4.2.1 lacks the corresponding __sync_* builtins on mips64. However, the builtins are now provided by Clang.
2021-07-08In recent libz update, tb@ overzealously attempted codesize reduction withTheo de Raadt
option BUILDFIXED -- which is incompatible with kernel hibernate unpack since it places side-effects into BSS, rather than inside z_streamp or using the private allocator. While here DYNAMIC_CRC_TABLE could cause similar problems, so disable this also. Space savings for the media is best done with bootblock-specific libz compile options, coming in the following commit. ok tb mlarkin

2020-07-09Fix a warning false positive from clang 10.Todd C. Miller
blf_enc() takes a number of 64-bit blocks to encrypt, but using sizeof(uint64_t) in the calculation triggers a warning from clang 10 because the actual data type is uint32_t. Pass BCRYPT_WORDS / 2 for the number of blocks like libc bcrypt(3) does. OK kettenis@

2020-05-19If we pass a packet length larger than 2^16, we should panic() insteadPatrick Wildt
of returning -1. With a return type of u_int16_t, -1 is not different to a valid checksum. For incoming packets, the header lengths don't exceed that size anyway, but for outgoing packets it's better to see if our bootloader crafts a broken one. Discussed with gerhard@ ok deraadt@ procter@
2020-05-18Sync in_cksum.c to the same version ospfd has. This fixes problemsPatrick Wildt
with odd packet lengths, which can happen when using TFTP to load a file with an odd length. ospfd actually took dvmrpd's version in 2006 to fix the same issue, and both daemons implementations are the same. For the bootloader we keep the consts from the previous version and replace the fatal with a print and return. ok deraadt@

2020-02-26Remove non-__STDC__ assert macros from <lib/libkern/libkern.h>.Visa Hankala
The macros are defined in a part of the header where a C compiler is required. In addition, the macros expand to C code, so it looks unnecessary to define the asserts with traditional cpp in mind. OK cheloha@, mpi@

2019-11-01Reduce BOOTRANDOM_MAX to 256. naddy pointed out there's no point havingTheo de Raadt
it larger than RC4STATE. A long discussion ensued. In conclusion all entropy inputs are either satisfactory enough, or just as shitty at 512.
2019-10-29Use arc4 to bit-spread the 512-byte random buffer over the .openbsd.randomdataTheo de Raadt
section, which has grown a fair bit with the introduction of retguard. Mortimer discovered the repeated 512-byte sequence as retguard keys, and this resolves the issue. (Chacha does not fit on the media, so 1.5K early drop RC4 is hopefully sufficient in our KARL link universe) Version crank the bootblocks. sysupgrade -s will install new bootblocks. ok djm mortimer

2019-08-03In the bootblocks, after discovering and opening /bsd.upgrade, fchmod -xTheo de Raadt
so the file cannot be re-executed upon the next boot. This provides a stronger one-shot-upgrade model than the upgrade script's rm /bsd.upgrade. Now various forms of upgrade failure will reboot into /bsd, which is probably more recoverable. Performing fchmod -x depends on (1) use of MI boot.c (not alpha/macppc/sparc64/sgi/octeon) and (2) "can write blocks" functionality in the IO layer. Most architectures have this support now. Two diagnostics "fchmod a-x %s: failed" and "/bsd.upgrade is not u+x" will remain in the tree while refinements happen for some of the laggard architectures. based upon a discussion florian tested in snapshots for more than a week without any complaints

2018-08-10Retry on incorrect passphrase for softraid crypto boot.Joel Sing
Historically, the softraid crypto support in the boot loaders has only given one attempt to provide the correct passphrase. There were a few reasons for this, including the fact that pkcs5_pbkdf2() allows an empty passphrase and that returning EPERM allowed for another attempt. With the event of KARL and the need for bsd.booted with hibernate resumption, this becomes much more of an issue - if you get the passphrase wrong you fail to resume. There are also other situations like using /etc/boot.conf to switch serial console, but an incorrect passphrase results in the config not being read. Also, bcrypt_pbkdf() does not permit empty passphrases. This reworks the softraid crypto support in the boot loaders so that it loops requesting a valid passphrase until one is provided, or an empty passphrase is entered (at which point it will abort). ok mortimer@ tb@
