2024-11-05The MI boot code used to have an infinite loop trying to boot the kernel,Miod Vallat
which got limited to at most two tries 26 years ago for the 2.3 release, but the documentation was never updated to match this change. Do it now. Reported by Nir Lichtman on tech@
2024-01-28Force -fno-stack-protector on "boot block" that absolutely can't haveTheo de Raadt
a stack protector (probably not even a -fstack-protector-strong) because the bloat would render them unuseable. This also means the system compiler can now take on any more it wants, and all the pieces which can't use the stack protector are properly marked. ok kettenis

2021-10-24For open/openat, if the flags parameter does not contain O_CREAT, theTheo de Raadt
3rd (variadic) mode_t parameter is irrelevant. Many developers in the past have passed mode_t (0, 044, 0644, or such), which might lead future people to copy this broken idiom, and perhaps even believe this parameter has some meaning or implication or application. Delete them all. This comes out of a conversation where tb@ noticed that a strange (but intentional) pledge behaviour is to always knock-out high-bits from mode_t on a number of system calls as a safety factor, and his bewilderment that this appeared to be happening against valid modes (at least visually), but no sorry, they are all irrelevant junk. They could all be 0xdeafbeef. ok millert

2020-12-09Use daddr_t and not daddr32_t in boot media.Kenneth R Westerback
At a minimum, amd64/i386 should now boot from 4TB GPT formatted disks. More daddr32_t terminations with extreme prejudice to follow. Tested by various, in snaps for a few days. ok deraadt@

2020-05-26/etc/random.seed reuse can now be detected. The stat +T bit marks the fileTheo de Raadt
(fchmod +T by bootcode, chmod 600 by /etc/rc). If the seed is reused, and HWRNG isn't available, the kernel won't get RB_GOODSEED indication...

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
2019-04-10change marks[] array to uint64_t, so the code can track full 64-bitTheo de Raadt
details from the ELF header instead of faking it. Proposal from mlarkin, tested on most architectures already
2019-02-24Remove -S from install commandskn
As of usr.bin/xinstall/install.c revision 1.68, -S is a no-op and install(1) will always create files safely, thus clean the option usage from the tree. Diff from Lauri Tirkkonen <lotheac at iki dot fi>, thanks.
